    1. In this project, the data workers serve as community researchers. Every community researcher works for two to four months on their inquiry and is compensated for all their working hours. We collaborate with data workers globally. A decisive sampling criterion is that these are data workers who are already organized in workers councils, unions, communities, or advocacy organizations.

      Coudl this be applied to sustainability working groups, Green Teams, and related ERGs?

    1. On the matter of regulation and legislation, the UK needs to adopt similar legislation to that already in place in the EU namely, the Taxonomy Climate Delegated Act, including the Assessment Framework, the Energy Efficiency Directive and its associated data centre delegated act to collect energy and other environmental data, this could be acheived by simply amending the existing Climate Change Agreement, extending the provisions to all data centres located in the UK and reducing the threshold for compliance reporting to 100kW.

      Interesting - he's 100KW is the value that would cover telecoms as well, I think

    1. Under the report’s net zero scenario, gas use would peak around the middle of this decade before halving by 2050, compared with 2022 levels. But the current trajectory suggests gas demand will continue to grow throughout the forecast, expanding by about a fifth by 2050.In the scenarios, demand for liquefied natural gas, which is cooled to be transported on ships, climbs by 40% and 30% above 2022 levels respectively.

      fall in oil, growth in gas

    2. BP has predicted that the world’s demand for oil will peak next year, bringing an end to rising global carbon emissions by the mid-2020s amid a surge in wind and solar power.

      Oil company says oil demand will peak next year

    1. Putting the various figures together shows that, far from the modest 29% year-on-year increase in the incomplete NBS data, there was a record 78% rise in solar generation in May 2024.

      This was compared to may 2023 - so a nearly 80% jump in a single year, for China (!)

    2. Clean energy generated a record-high 44% of China’s electricity in May 2024, pushing coal’s share down to a record low of 53%, despite continued growth in demand. The new analysis for Carbon Brief, based on official figures and other data that only became available last week, reveals the true scale of the drop in coal’s share of the mix. Coal lost seven percentage points compared with May 2023, when it accounted for 60% of generation in China.

      Next year coal will be below 50% in China if the pace is kept

    1. They present a significant policy opportunity supported by the country’s ongoing efforts to develop the green bond market and can catalyze promoting green and high-quality development, creating jobs, and delivering environmental benefits.The Greenpeace East Asia report analyzed over 8,000 projects covered by newly issued provincial and municipal government bonds in 2021 as a sample and found that one in five could have been issued as such Green and Sustainable Municipal Bonds.2

      so basically, assuming there is a market for green bonds in the private sector, there are loads of 'bondable' projects

    1. “For our customer base, there's a lot of folks who say ‘I don't actually need the newest B100 or B200,’” Erb says. “They don’t need to train the models in four days, they’re okay doing it in two weeks for a quarter of the cost. We actually still have Maxwell-generation GPUs [first released in 2014] that are running in production. That said, we are investing heavily in the next generation.”

      What would the energy cost be of the two compared like this?

    1. As solar is displacing traditional assets, such as gas power plants, we are observing a relatively sharp increase in the price of some of the power reserves, which happens in the opposite direction than the prices on the day-ahead markets.

      This implies a massive rise in value for being able to provide reserve dispatchable power, like from batteries

    1. Germany's coalition government is set to overhaul the way renewable energy is subsidised so that power producers would get one-off support for their investment costs instead of a guaranteed price for power they produce, a finance ministry document showed on Friday.

      So this would either:

      a) reduce the need to borrow so much cash from risk averse bankers b) not really help with the price volatility / merchant risk thing that makes it hard to get finance

    1. Mark Boost, CEO of UK-based cloud company Civo is similarly disappointed in the outcome.Boost said the deal is "not good news" for the cloud industry, and added several important questions still need to be answered."We need to know more about how the process of compensation will work," he said. "Will all cloud providers in Europe be compensated, or just CISPE members? Is this a process that will be arbitrated by Microsoft? Where are the regulators in this?"Boost added that the deal will benefit CISPE members only in the short term, but that the cloud industry and its customers will pay the price in the long-term.

      This is a bit like how AWS will share sustainabilty data under NDA - works for that provider, but not everyone else.

    1. However, EFRAG's move to publish a draft for consultation at the same time as the ESRS at the end of January 2024, which is aimed at SMEs not covered by the CSRD, came as a surprise: With the so-called Voluntary ESRS for Non-Listed Small- and Medium-Sized Enterprises the "VSME ESRS", EFRAG is addressing all those companies that are not covered by the CSRD and thus the aforementioned concretisations (i.e., ESRS and ESRS LSME), but which nevertheless wish to take similar measures.

      So basically this some guidance on what companies who aren't covered by the CSRD ought to cover to demonstrate following the intent of the law

    1. To start, titanium ore is heated to 1,800 degrees Fahrenheit and reacted with chlorine gas and carbon-rich petroleum ​“coke.” This step yields a liquid chemical, titanium tetrachloride, and also produces carbon dioxide as a byproduct (similar to how blast furnaces for ironmaking release CO2).

      I didn't realise Titanium relied on electrolysis like alumnium too

    1. There also exist well-known vulnerabilities for eBPF programs, which can allow attacksto break container isolation [13] and execute malicious code inthe kernel [22]. Since Wattmeter is built on top of eBPF and ac-cesses RAPL information, only privileged users should be allowedto access it.

      So, vulnerable to platypus attack?

    2. Figure 3 shows the effect of EFS on the CPU and energy sharesbetween the two processes

      it shows them using about the same power instead of the visible difference on the charts

    3. Another framework for implementing custom scheduling poli-cies without direct kernel modification is Meta’ssched_ext.sched_extis a Linux kernel patch that proposes a new abstract schedulerclass, which can be instantiated with scheduling programs in eBPFat runtime. There are ongoing discussion of upstreamingsched_extinto Linux. We have chosen to implement the scheduling poli-cies proposed in this paper with ghOSt, but it is also possible toimplement them withsched_ext

      Wow, it might actually be upstreamed into linux proper?

    1. He added that private companies, which will have a significant role in the transition, want to see policy certainty enhanced in the months ahead. The group is awaiting the finalisation of the Electricity Regulation Amendment Bill, which promises to open up the electricity market and put an end to Eskom’s longstanding monopoly, and the Integrated Resource Plan.

      So, a market with more private generation firms, I'm guessing

    1. consumes 19% less energy per event in high performance mode

      in high power mode, it's more efficient for the amount of power it uses?/

    2. %. This shows, that the impact of load shaping heavily depends on the power proportionality53 of the underlying hardware, and that it is not a reasonable measure per se.

      Ah, so assumptions about physical hardware can't be blindly applied to cloud. Assuming the TEADS model is accurate

    3. Although solar forecasts are not very promising this time, it again permits to discharge to 30%, as the carbon intensity during the next day is expected to be especially low. Instead of drawing carbon-intensive grid energy at night, the demand is thereby shifted to the next morning where the batteries are charged to 60% using cleaner energy.

      In this case local generation is low, but the grid is relatively clean (maybe it's v windy, not sunny), so it's ok to run down the local store of greener energy in the battery

    4. Although the carbon-aware experiment uses 2.4 % more energy than the baseline (which is because not all power modes have the same energy-efficiency), its associated carbon emissions through grid power consumption are 35.9 % lower. In the following, we will briefly analyze the two experiments and to demonstrate how our integration enables research and development of carbon-aware applications.

      How much power draw compared to the battery does this set up have? 32,000 mAh would be how long at max power draw for a Pi?

    5. The control unit adaptively adjusts the battery's minimum state of charge and grid charge rate over time. In particular, in case of promising forecasts for solar power production or low carbon intensity, it is able to temporarily deplete the battery to 30%.

      So, PUT ing to the /soc end point with target charge and a new C value

    6. This is especially the case when not testing virtualized applications on powerful hardware but embedded systems that often only run only one energy-hungry process at a time. In these systems, load shaping is likely rather performed on a device level, for example, through DVFS.

      Also with exclusive use of a GPU server, right?

    7. Therefore, if applications under test are deployed on physical nodes like single-board computers, it is recommended to use dedicated hardware for measuring the power usage of these devices. For example, in our experimental testbed we monitor the current and voltage of a RaspberryPi 4b with a USB to USB measuring device equipped with an INA219 DC current sensor.

      What kit has a INA219 DC current sensor these days? How can I buy one?

    8. Note: The physical node's power usage is controlled via DVFS, while the virtual node uses rate limiting on the executed process.

      Ah, two strategies for "Change the speed" of the three approaches I list in this post

    1. “These claims assume that a company that pollutes more now should be able to pollute into the future. This means Global North companies will continue to inequitably dominate use of our remaining carbon budget. These findings should raise real questions for any bodies that claim to set standards for voluntary corporate climate targets,” David Tong, Global Industry Campaign Manager for Oil Change International, said.
    2. A major blindspot is the fact that SBTi does not take into account new companies with their share of emissions coming into existence in the future. In SBTi’s framework, existing companies are allocated a share of the carbon budget without leaving any room for new players, some of whom might be more efficient or even working in the decarbonisation space like solar technologies. This further entrenches fossil fuel developments by existing companies and also raises questions about equity.

      New firms could be better than incumbents as emissions are ring fenced for incumbents

    3. Net-zero corporate pledges are voluntary, which means they can be reeled back in as quickly as they are announced.Shell scrapped its emission reduction target for 2035 when it sought to grow its gas business, for example, and BP walked back on some of its climate commitments when profits hit a record high. An Oil Change International assessment of the climate plans of eight oil majors—Chevron, ExxonMobil, Shell, TotalEnergies, BP, Eni, Equinor, and ConocoPhillips—released this year found that all eight continue to drive fossil fuel expansion and six have explicit goals to grow their total production volume this decade
    4. Not all do so and there is no agreement on what a fair share is, but by claiming an individual target is Paris compliant is implicitly making an ethical claim that this represents your fair share of the global response, without saying how it is fair,” she said.
    5. The Climate Policy paper points to issues that arise when individual countries or companies link their efforts to mitigate climate change to Paris Agreement goals. If such linking is indeed necessary, the authors say that assumptions about time scale, spatial scale and equity must be included in the analysis and presented transparently.The paper is “a welcome contribution” because it asks countries to center mitigation claims in a context of national contributions to global fair shares of the climate response, said Kate Dooley, a research fellow in the School of Geography, Earth and Atmospheric Sciences at the University of Melbourne. At present, many wealthy countries have exceeded their fair share of the carbon budget.
    6. The distribution of emissions over time is not just a question of cumulative global emissions—it’s also a matter of equity. Rich, industrialized countries have already claimed a disproportionate share of the carbon budget that has brought us to around 1.2°C warming today. The U.S. has emitted about 25 percent of cumulative emissions; Europe, meanwhile, has emitted around 20 percent.

      Good point

    1. In fact, capturing CO2 from ethanol production is so easy that ethanol production is the biggest source of purified CO2 in the US, and the second biggest source in Europe. This is where we source the CO2 that we use in fizzy drinks, food production, fire extinguishers, etc.

      Interesting. I thought it was Steam Reformed Methane

    1. it did so by taking some short cuts. Android itself was an acquisition in 2005 (for $50 million, with a keyboard interface) and, in response to the iPhone, a new touch user interface was developed

      I totally forgot that android was an acquisition

    1. In their annual financial report, companies will have to disclose sustainability information in the management report. The details of the sustainability information to be published are set out in Commission Delegated Regulation (EU) 2023/2772 of 31 July 2023, to which the French Decree 2023-1394

      So, 2023-1394 is the thing to keep an eye on

    1. That’s no small task: In 2022, SAP spent approximately €7.2 billion in purchases from more than 13,000 suppliers worldwide, its annual report shows; 30% of that being on cloud services – more on that below.

      7.2bn - nearly 2bn is spend on cloud, all by themselves?

    2. He is referring to a mechanism SAP first tested in 2016 across 10 countries. This prices CO2 (from €40 to €400 per ton; depending on the flight and its distance) to release money for sustainability initiatives, as SAP ramps up not just its own internal decarbonisation programme (it aims to reach net zero by 2030) but continues to build out a suite of sustainability products for its expansive customer base.

      SAP have been using internal carbon pricing, for nearly ten years, and they are sophisticated enough to have different prices even within aviation

    1. As 45% of last year’s record solar additions were distributed generation, the exclusion of small solar installations is affecting these numbers a lot more than it used to.

      Wow, nearly half of China's solar addition is distributed? How is it funded?

    1. If there was one universal piece of advice I had for marketers seeking to broadly improve their organic search rankings and traffic, it would be: “Build a notable, popular, well-recognized brand in your space

      Recognisable brand, over content?

    2. A module on “Good Quality Travel Sites” would lead reasonable readers to conclude that a whitelist exists for Google in the travel sector (unclear if this is exclusively for Google’s “Travel” search tab, or web search more broadly). References in several places to flags for “isCovidLocalAuthority” and “isElectionAuthority” further suggests that Google is whitelisting particular domains that are appropriate to show for highly controversial of potentially problematic queries. 

      We know they whitelist electrion sites. Would they do this with climate science

    1. Our study suggests the transformation pathway will have three main phases.

      peaking (slowing down fossil deployment and ramping up clean gen), then energy revolution (bulk transition), then consolidation (clean up)

    2. Meanwhile, gas does not play a significant role in the power sector in our scenarios, as solar and wind can provide cheaper electricity while existing coal power plants

      This is a surprise. I had assumed China might shoot for gas in as a stop gap too, but it looks like they're skipping it

    3. The upper panel in the figure shows the installed capacity of coal power plants and the lower panel their electricity production from 2021 to 2060.

      Wow, China has more than a terawatt of coal generation in 2024

    1. What is happening in China with electric vehicles is pretty stunning. China is the world’s largest auto market by far — in 2022 China sold 26.8 million vehicles, the U.S. sold 13.8 million and Japan was third with 4.3 million.

      Holy shit.

      If EVs are making half the cars sold in China, then are more EVs are being sold in China than cars and trucks in the USA ?

    1. There is mounting evidence that the demand for imported cooking oil in the UK and Europe is being met with virgin palm oil that has been fraudulently passed off as waste. This would cancel out the fuel’s emissions savings, due to the land clearances for oil palm plantations.

      YIIIIIKES

    1. To produce the 12,750 MWh that will be generated by the data center at full capacity, 2660 t of pellets would have to be burned per year

      This suggests that SIg is buying the heat, which is what makes the whole thing economically workable

    2. Instead of wasting the 45°C hot air from equipment and servers in the atmosphere, the new data center will inject this flow into air-to-water heat pumps; these will raise the temperature from 45°C to 67-82°C in order to adapt to the current requirements of the district heating installations of Services Industriels de Genève (SIG).

      This suggests they are just complying with the law now? Or are they going beyond what is required?

    1. First, it will require the operators of regional grids across the country to forecast their region’s transmission needs a full 20 years into the future, develop plans that take those forecasts into account, and update those plans every five years. In practice, this should mean a more robust consideration of new wind and solar options, as well as greater adherence to the net-zero emissions targets set by many U.S. states.

      how far ahead did they need to forecast before?

    1. Over the past three years, battery storage capacity on the nation’s grids has grown tenfold, to 16,000 megawatts. This year, it is expected to nearly double again, with the biggest growth in Texas, California and Arizona.

      10x in 3 years?!

    1. The critical sixth key was the contest key: Bernie Sanders’s contest against Clinton. It was an open seat so you lost the incumbency key. The Democrats had done poorly in 2014 so you lost that key. There was no big domestic accomplishment following the Affordable Care Act in the previous term, and no big foreign policy splashy success following the killing of Bin Laden in the first term, so there were

      Bernie sanders was the missing key for the Hillary loss then?

    1. Now, the United Nations has taken a first step toward filling in these data gaps with the latest installment of its periodic report on e-waste around the world. Released last month, the new Global E-Waste Monitor shows the staggering scale of the e-waste crisis, which reached a new record in 2022 when the world threw out 62 million metric tons of electronics. And for the first time, the report includes a detailed breakdown of the metals present in our electronic garbage, and how often they are being recycled.
    1. Following an attributional approach, and with the assumptions retained, the Iroco study evaluates the greenhouse gas emissions attributable to one week's use of a mailbox at 63.2 gCO2eq.

      So about 3.5 kg per year

    1. However, corporate governance in the telecoms sector is notconducive to the kind of radical decisions that separationrequires. Decision makers and boards are incentivised onmetrics that require short term continuity, not disruption

      So to make this argument in cloud/AI, you need to make the argument that firms are too conservative in terms of corporate structure, and as a result are missing out on greater value coming from two individually more valuable entities - something that the org or compensation structure is not set up for

    2. Rural broadband in Europe is increasingly deployed in aneutral host model with a single fibre networkconnecting homes and multiple service providersdelivering services over that network.

      This is like the unbundled approach already then

    3. as pure infrastructure players borrow atlower rates and expect lower returns, they will deployinfrastructure where vertically integrated players won’t,and with no (or less) public subsidies;

      Infra with more patient capital isn't chasing such high risk returns like getting everyone to buy into AI

    4. We have one leading example of voluntary structural separationresulting in increased valuation of the separated entities -Telecom NZ, in 2011. Post de-merger, after years of flat marketvaluation, both Chorus (infrastructure) and Spark (services) sawshare prices rise. Between 2015 and 2023, the combined market1 Tower companies (or towercos) are infrastructure companies that managemobile towers for multiple mobile network operators.capitalisation of Chorus and Spark grew by 150%, whereas thatof European and US vertically integrated telcos2 grew only by15%.The plan also delivered full FTTH coverage to 87% of NewZealand homes with 72% adoption.

      So breaking them made led to greater share price raises AND better service in New Zealand

    Annotators

    1. So should we collectively accept a radical shift in our policy and regulatory framework in order to ensure that the beacon of the European economy can deploy infrastructure that Sweden, Denmark, Spain, France, and many of the smaller European countries started successfully deploying long ago? This, in a nutshell, is why the Commission never talks about Germany.

      This appears to be making the argument that rather than admit Germany has underinvestment compared to the rest of the EU, it's easier to change all the entire EU telecom policy so vertically integrated telcos can make a better return.

    1. The article confirms many of my suspicions — that, as The Information wrote, "other software companies that have touted generative AI as a boon to enterprises are still waiting for revenue to emerge," citing the example of professional services firm KPMG buying 47,000 subscriptions to Microsoft's co-pilot AI "at a significant discount on Copilot's $30 per seat per month sticker price." Confusingly, KPMG bought these subscriptions despite not having gauged how much value its employees actually get out of the software, but rather to "be familiar with any AI-related questions its customers might have."

      This seems like spending 17 million a year to help them sell consulting about what AI.

    1. It's important to understand these complexities because they are currently being flattened not just by corrupt government officials in Global South countries or fossil fuel executives in Texas, but also by a whole ecosystem of pundits like Jordan Peterson, Michael Shellenberger, Alex Epstein and even Joe Rogan, who use the idea that fossil fuel development will solve poverty in Africa as justification for continuing fossil fuel's dominance in the world. In fact, fossil fuel development hasn't even solved energy poverty in the African countries that have embraced it; Nigeria has the continent's largest and oldest fossil fuel industry and yet still has the world's lowest energy access rates.

      Wow, I had no idea that energy access was so low in like this.

    1. To plug the financing hole Intel has had to rely on a wide variety of capital sources to fund everything: traditional debt financing, government support, and even more creative financial engineering schemes like the Brookfield fab deal to find a way to pay for everything.

      thisis what? around 60bn of government subsidy?

  6. Mar 2024
    1. As noted by researchers at the University of Oxford and the Mercator Research Institute on Global Commons and Climate Change, carbon-intensive sectors like electricity generation actually contribute relatively little to the world economy, compared to high-value but lower-emitting sectors like IT, real estate, and social work. 

      what? the industries below RELY on electricity!

    1. The above report is an underestimation of datacenter power demand, but there are plenty of overestimates too

      Wow, so semi-analysis is seeing the IEA estimates as a low ball? I did not see that coming

  7. Feb 2024
    1. The FTC, of which Khan is now chair, contends that Amazon has found a way to push up prices after all, without losing shoppers. It does this, the FTC argues, by imposing ever-higher fees on third-party sellers, who have no choice but to pass these costs on to shoppers by raising their prices. If those businesses try to sell more cheaply elsewhere, Amazon throttles their sales on its platform—which, thanks to the central place in e-commerce that Amazon has built up over the years, can be a death sentence for these businesses. So, according to the FTC, sellers generally absorb the high fees by inflating their prices not just on Amazon but across the web—precluding the price competition that could loosen Amazon’s grip on e-commerce.

      This sounds like the "favoured nation status" from Cory's book

    1. The disclosure required by paragraph 33 shall include the total energy consumption in MWhrelated to own operations as follows
    1. and superconductors will at some point do to conventional power cables what fibre-optics did to conventional telephone cables.

      ? I assume this is referring to stuff like graphene.

  8. Jan 2024
    1. Because we use systemd for most of our service management, these stdout/stderr streams are generally piped into systemd-journald which handles the local machine logs. With its RateLimitBurst and RateLimitInterval configurations, this gives us a simple knob to control the output of any given service on a machine. This has given our logging pipeline the colloquial name of the “journal pipeline”, however as we will see, our pipeline has expanded far beyond just journald logs.

      I did not expect to see journald being used as the basic building block

    1. Overall, Iceland produces approximately 20 terawatt hours of electricity per year.

      About the same as Google?

    2. Landsvirkjun built Kárahnjúkar despite protests, it started operating in 2009. But the controversy changed Iceland's energy policy. A fourth aluminium smelter was never finished, and in an announcement made in 2022, Landsvirkjun writes that it "will for the time being not focus on attracting new large-scale customers in the metal industry or other industrial commodities."

      I did now there was push back even power in Iceland

    1. Meta previously bet on CPUs and its own in-house chips to handle both traditional workloads and AI ones. But as AI usage boomed, CPUs have been unable to keep up, while Meta's chip effort initially fizzled.

      I did not know they tried to make their own chips

    1. It’s past time for the IT and BPO Services industry to jump to a new S-curve driven by technology arbitrage if they wish to get back to another season of hockey stick growth:

      Yikes. So basically, time to fire the people we outsourced to, and replace them with ChatGPT ?

    1. wrote about this in 2012 in a book called Liars and Outliers. I wrote about four systems for enabling trust: our innate morals, concern about our reputations, the laws we live under, and security technologies that constrain our behavior. I wrote about how the first two are more informal than the last two. And how the last two scale better, and allow for larger and more complex societies. They enable cooperation amongst strangers.

      Morals and reputation

      Laws and tech

    1. They were national strategic programs. The strategic programs were aligned with nuclear weapons programs. The government picked and enforced a single design for all of the reactors. The reactors were GW-scale due to thermal efficiencies required for cost effectiveness. The government ran human resourcing. The programs ran for 20 or 30 years. They built dozens of nuclear reactors to maintain the teams and momentum and to share lessons learned.

      These are 5he seven conditions necessary for nuclear to work, asked on the historical evidence

    2. A key point to remember about the US DOE is that 55% of its budget is related to commercial nuclear generation. The other 45% covers dams, geothermal, wind, solar, tidal, wave, biomass and biofuel energy.

      An! Numbers here! This is super helpful!

    1. A second MoU on gas export partnership was agreed between Riverside LNG of Nigeria and Germany's Johannes Schuetze Energy Import AG. Under the accord, Nigeria will supply 850,000 tons of natural gas to Germany annually which is expected to rise to 1.2 million. The first deliveries will be in 2026, Ngelale said.The deal will help process about 50 million cubic feet per day of natural gas that otherwise would have flared.

      ok, so instead of being flared for no money, it's being bought by German to burn instead.

    1. Volkswagen teamed up with ClimatePartner GmbH to generate offsets so it can be “independent from the market where you can’t control what’s effective and what’s not,” said Esra Aydin, a spokesperson for the automaker. But the credits didn’t materialize in time last year and it ended up going back to the voluntary market where cheap renewable-energy credits were the only ones that worked with its budget.

      "Worked with its budget"

    2. In other words, the companies decided some offsets weren’t good enough to meet their own climate goals — and yet have continued selling them to customers as a feel-good solution.

      That's a quite a quote

    1. In contrast with the precipitous fallings-off of platforms like Myspace and LiveJournal, the decays of which have been clear and irreversible, Tumblr has kept defying expectations and stayed somewhat thriving against all odds. That is, in part, thanks to the guidance and guardianship of Automattic, which acquired Tumblr for the bargain-bin price of $3 million.

      Holy balls. Only three mil?

    1. The two corporations aren’t directly buying fuel from World Energy. Instead, they’ll purchase certificates representing SAF that gets pumped into the larger supply chain — then count the associated carbon reductions toward their sustainability goals. Microsoft agreed to buy certificates representing 43.7 million gallons of SAF over a 10-year period, while DHL signed a contract for 177 million gallons over seven years.

      These are basically like EACs for fuel!

    1. Provided that reliability and supply improve, the grid could become the optimal solution to provide almost 60% of people with access to electricity in each scenario.In the AC, Nigeria achieves universal access by stepping up efforts to provide off-grid solutions to those populations that live far from a grid.

      Wow, really that much off grid generation?

    1. However, some have criticised the CIPP for providing market-rate loans rather than special financing schemes, which will lead to high costs for Indonesia and could deter other countries from accepting similar deals in the future. 

      Ouch! What's the interest rate in Indonesia compared to North America for energy infra?

    1. Here’s another problem: from 2020 to 2022, shopify claims around 31,000 tonnes of carbon removal. But according to the CDR.FYI database, only 4,000 of the tonnes they have purchased have been actually physically removed from the atmosphere

      If you have increases in temporal resolution for electricity, why not for CDR?

    2. Shopify don’t count the emissions footprint of the products sold by merchants in their actual climate data. No shipping, no manufacturing emissions, nothing (Amazon play a similar trick).

      This an interesting point - shopify can argue they do it to avoid double counting, but that’s not really what scope 3 is designed for

    1. It spent just over $5m to advertise its compact Bolt option over the same time period. Ford spent $61.2m (£48.7m) to advertise its electric F150 , and around $9m to advertise its mid-size electric Mustang. Among the top automotive advertisers, only BMW and Hyundai are spending as much or more to market their more efficient EVs.

      the f150 is its biggest selling autombile. I'd assume this would be higher though, surely?

    1. The CDP, previously known as the Carbon Disclosure Project and the most comprehensive global registry of corporate carbon emission commitments, recently said that of the 19,000 companies with registered plans on its platform, only 81 were credible.

      Sheesh, less than half of one percent of the plans shared with CDP were credible?

    1. Over a year that equates to roughly seven million in savings and is precisely why the biggest names in tech are moving to colder, more remote locations.

      How big does a DC need to be for this 7 million?

    2. Downtime costs roughly $10,000 perminute in a hyperscale and is categorised as the highest risk.

      This is pretty wild quote. I wonder what the source is?

    1. CSP makes it possible for server administrators to reduce or eliminate the vectors by which XSS can occur by specifying the domains that the browser should consider to be valid sources of executable scripts. A CSP compatible browser will then only execute scripts loaded in source files received from those allowed domains, ignoring all other scripts (including inline scripts and event-handling HTML attributes).

      I don't think I've come across this before but I did on a recent project. I didni't know you could block inline styles or inline javascript in this way

    1. The approximate cause of power problems often isn’t that hard to find. Fixing them is often the hard part. Good luck.

      Quotable

    2. Intel processors also support multiple P-states. P0 is the state where the processor is operating at maximum frequency and voltage, and higher-numbered P-states operate at a lower frequency and voltage to reduce power consumption. Processors can have dozens of P-states, but the transitions are controlled by the hardware and OS and so P-states are of less interest to application developers than C-states.

      These exist too, but we can only control them indirectly at best.

    3. Intel processors have aggressive power-saving features. The first is the ability to switch frequently (thousands of times per second) between active and idle states, and there are actually several different kinds of idle states. These different states are called C-states. C0 is the active/busy state, where instructions are being executed. The other states have higher numbers and reflect increasing deeper idle states. The deeper an idle state is, the less power it uses, but the longer it takes to wake up from.

      Mental note: Think "C for the CPU cool down"

    1. Even before Hardin’s ‘The Tragedy of the Commons’ was published, however, the young political scientist Elinor Ostrom had proven him wrong. While Hardin speculated that the tragedy of the commons could be avoided only through total privatisation or total government control, Ostrom had witnessed groundwater users near her native Los Angeles hammer out a system for sharing their coveted resource. Over the next several decades, as a professor at Indiana University Bloomington, she studied collaborative management systems developed by cattle herders in Switzerland, forest dwellers in Japan, and irrigators in the Philippines. These communities had found ways of both preserving a shared resource – pasture, trees, water – and providing their members with a living. Some had been deftly avoiding the tragedy of the commons for centuries; Ostrom was simply one of the first scientists to pay close attention to their traditions, and analyse how and why they worked.
    2. The features of successful systems, Ostrom and her colleagues found, include clear boundaries (the ‘community’ doing the managing must be well-defined); reliable monitoring of the shared resource; a reasonable balance of costs and benefits for participants; a predictable process for the fast and fair resolution of conflicts; an escalating series of punishments for cheaters; and good relationships between the community and other layers of authority, from household heads to international institutions.
    3. Among his proposed solutions to the tragedy of the commons was coercive population control: ‘Freedom to breed is intolerable,’ he wrote in his 1968 essay, and should be countered with ‘mutual coercion, mutually agreed upon’. He feared not only runaway human population growth but the runaway growth of certain populations. What if, he asked in his essay, a religion, race or class ‘adopts overbreeding as a policy to secure its own aggrandisement’? Several years after the publication of ‘The Tragedy of the Commons’, he discouraged the provision of food aid to poorer countries: ‘The less provident and less able will multiply at the expense of the abler and more provident, bringing eventual ruin upon all who share in the commons,’ he predicted. He compared wealthy nations to lifeboats that couldn’t accept more passengers without sinking.

    3. there are well understood risks of turning unchaperoned engineers loose on social problems. And more so as the engineering tools become more specialized: if your only tool is an abstract algebraic curve, all the world becomes a cryptographic nail. 

      Crypto as the hammer that turns everythign into a nail.

    4. This liminal space, often vaguely described as the “Internet of Things” (IoT) doesn’t hold much resemblance to the Internet, at least as originally conceived. And the “things” commonly encountered are toasters, washing machines, and toothbrushes, with an often inexplicable desire to “connect.”
    5. IoT’s current failures are also an opportunity. Beyond the absurdity of overly chatty microwaves, plugging the physical world directly into extractive (and often tenuous) business models has raised public awareness of the shortcomings of how we currently build digital infrastructure. Whether it’s a bike that stops working when its manufacturer goes bankrupt, or a home appliance with unclear allegiances, it has created real harms from exfiltration of personal data, and unnecessarily reducing the lifespan or increasing fragility of devices we depend on as part of daily life.

      Overly chatty microwaves, and home appliances with unclear allegiances - there are so many quotable bits in this post!

    6. a home appliance with unclear allegiances,

      This is wonderful turn of phrase

    1. For an example of an unintended consequence, let’s say the result of your optimization project is spare capacity at a cloud provider. Then that capacity is then offered on the spot market, which lowers the spot price, and someone uses those instances for a CPU intensive workload like crypto or AI training, which they only run when the cost is very low. The end result is that capacity could end up using more power than when your were leaving it idle, and the net consequence is an increase in carbon emissions for that cloud region.

      This is because capacity, utilisation and power used are related, but different concepts.

      Your capacity, which you share back to the pool is then avaiable to someone else, who ends up buying it to use for a task that has a higher average utilisation, resulting in more power being used in absolute terms, even if less is attributed to you.

      This also raises the question - who is responsible - the customer for making the capacity available, for the cloud provider who accepts this workload?

      The cloud providers get to set the terms of service for using their platform.

    2. Average retail electricity rates in Hawaiian Electric territory are higher today than they were a decade ago, per state data. Kauai’s rates have dropped from the highest in the state to the lowest, as KIUC shifted from costly imported fossil fuels to cheaper solar generation.

      WOW

    1. but also depend on a global renewable energy production whose capacity cannot exceed 30% globally (EIA),

      I don't understand this reference

    2. It should be noted that in France, regulations do not allow this market-based approach when reporting company level CO2e emissions : “The assessment of the impact of electricity consumption in the GHG emissions report is carried out on the basis of the average emission factor of the electrical network (…) The use of any other factor is prohibited. There is therefore no discrimination by [electricity] supplier to be established when collecting the data.” (Regulatory method V5-BEGES decree).

      Companies are barred from using market based approaches for reporting?

      How does it work for Amazon then?

    1. In the end, there was an undisclosed settlement between Verizon and Mozilla, but ComputerWorld later reported that financial records showed a $338 million payment from Verizon in 2019. On top of revenue-sharing with Google, that payment drove up Mozilla's revenue, which in 2019 reflected "an 84 percent year-over-year increase" that was "easily the most the open source developer has booked in a single year, beating the existing record by more than a quarter of billion dollars," ComputerWorld reported. Perhaps that bonus payment made switching back to Google even more attractive at a time when Baker told the court she "felt strongly that Yahoo was not delivering the search experience we needed and had contracted for."

      Wow, it represented a 340 million USD bonus to switch from Yahoo to Google?

    1. Finally, over a longer time frame, novel technologies could drastically lower battery-related mineral demand for nickel and copper in particular, but the mineral intensity of next-generation battery chemistries remains uncertain and could even increase demand for some battery minerals. For example, solid-state battery chemistries could increase lithium demand by up to 28%.11

      Why are we not talking about copper and nickel, and talking so much about lithium and conbalt?

      Is it just the relative novelty?

    2. Figure 1. Comparison of ore extraction in IEA NZE scenario and sensitivity of substantially improved recycling and potential ore grade decline

      This implies that total mining would go DOWN under a transition, possibly by half.

      The ore grade decline is less of an impact than I expected too.

    3. Ore extraction is largest for EVs, growing 55 times from 2021, compared to 13 and 9 times for solar PV and wind power, respectively

      The share of mining going to cars is not really something we discuss in digital technology discussions enough

    4. This means that the high demand for minerals through the energy transition is of a (temporary) stock building nature, while fossil-related extraction is continuous and dissipative. In the longer term, the decommissioning of end-of-life renewable generation provides opportunities for reuse or recycling. This can mitigate demand of primary produced minerals for new renewable installations

      We can use the byproducts of critical mineral mining. Not so much with fossil fuels

    1. For starters, if you are seeking to use a green financial instrument to finance your data construction project anywhere in the world, and have European investors, then the Taxonomy Climate Delegated Act (TCDA) will apply. This requires the operator to implement 106 of the EU Code of Conduct for Data Centre (Energy Efficiency) best practices as well as undertake various other activities

      Oh, this is new to me - if you want the cheap money, yo need to meet the ECOCDC

    1. While it is capable of providing constant power, hydrogen fuel cells are also being considered for providing backup power to data centers. This is greatly appealing to data center operators as a more environment-friendly replacement for traditional diesel generators. This change would see the use of fast-start fuel cells, such as proton exchange membrane (PEM) fuel cells which could take the place of diesel generators.

      Proton exchange membranes are presumably the newer types of fuel cells, that are more flexible and need less heat, but are more pricey

    2. The key benefit and primary motivation for installing hydrogen fuel cells within a data center is to reduce carbon emissions. As stated, some fuel cells, such as SOFCs, can use natural gas. While it is less damaging to the environment than diesel, it still results in significant carbon emissions.

      Is this some of the missing context for the CCS next to datacentre patents from M$?

      If you can capture the CO2, and use the waste heat to separate the CO2 from the absorbing material, then it might improve the economics of the SOFC fuel cells, AND deal with the CO2 emissions problem.

    3. SOFCs and PEM fuel cells differ from one another in their construction, materials, and operation. In a high-level view, the primary differences are the electrolyte materials (where the hydrogen and oxygen react) and operating temperatures. SOFCs operate at high temperatures, requiring longer start-up times and as a result, only being suitable for continuous power supply. PEMs, by contrast, operate at lower temperatures and are capable of fast-start or continuous operation, but are a more expensive option.

      Oh wow, so there are two kinds of fuel cells, and the expensive one is the fast ramp up one

    4. The majority of fuel cells currently in use in data centers are solid oxide fuel cells (SOFCs), providing constant power. SOFCs can generate power through the conversion of fuels such as natural gas and biogas, into hydrogen, which is then reacted in the fuel cell to generate power. While using natural gas still results in carbon emissions, SOFCs are able to generate power with higher efficiency than combustion engines. SOFCs can also be fuelled directly with hydrogen, although this is not the norm due to hydrogen’s cost and availability.

      Wow, greater efficiency than gas turbines / engines?

    1. decade ago, these plants provided “low carbon” electricity in comparison to the grid at the time, but now in many cases, emit more carbon than local grids. Countries that already have decarbonized grids, France, Sweden, and Scotland, for example, will not benefit from a continuous system that uses natural gas to begin with.

      What would the green premium be for bio methane in this scenario? As in Methane from bio genie sources. Supply issues aside, obvs.

    2. One suggestion is for greater integration of energy systems, which would see data centers located adjacent to energy industries or having data centers integrated with hydrogen-generating plants and fuel cells. This solution sidesteps planning problems by locating data centers alongside low-carbon energy industries. A major issue with this (aside from the available land) is blurring the lines between the data center operators, utility providers, and energy companies.

      This flips the assumptions of what a datacentre looks like, if the power density keeps increasing, instead of a DC with on-site power, you might have a power with on-site DC

    3. From a mechanical perspective, designing a hydrogen storage system is significantly more complex than a diesel storage system. Hydrogen has more storage options available however, it presents higher risks than diesel such as greater flammability and explosivity, higher pressures, potential for low temperature, or chemical storage methods which are all hazardous. This therefore requires the mechanical design for such a system to comply with rigorous safety standards.

      Ok, so h2 unsurprisingly is wast more explodey, and hard to store safely and cheaply

    1. And if you look at the total consumption of semiconductors by the Chinese manufacturing industry, then China imports more semiconductors than they import oil.

      China spends more importing semiconductors than on importing oil? really?

      This is from Peter Wennink, CEO of ASML

    1. Google has argued that switching search engines is just a click away and that people use Google because it's the superior search engine. Google also argued at trial that Microsoft's failures with Bing are "a direct result of Microsoft’s missteps in Internet search."

      This is interesting - I wonder how 3rd parties like Mozilla or Vivaldi testify?

      If they say it's hard, they contradict their own marketing, and risk their main source of revenue.

      If they say it's easy, they risk undermining all their own comms around the importance of choice, and the necessity of more diverse ecosystems.

    1. Provide a transitional implementation for network operators and protocols that do not yet support standards-based Layer 2-3

      This suggests to me that there is a lot of proprietary layer 2-3 in IOT. Is this the case?

    1. Despite the unknowns, the technology definitely piques the interest of owners and operators of data center facilities, with analyst firm Omdia noting that more than 80 percent of survey respondents will most likely deploy grid-interactive UPSs within the next five years. As usual for this industry, the technology will require more deployments and for it to mature before it becomes the standard way data centers and other mission-critical facilities will be built.

      I wonder how much extra flex and capacity this would represent?

    2. While exact numbers are not disclosed, such as battery capacity and how much Microsoft is willing to make available for grid interactivity, the company claims that, over the next couple of years, this move will remove about two million metric tons of carbon dioxide emissions that would otherwise be generated from Ireland’s National Grid.

      This is about an eighth of Microsoft's reported emissions in 2022, I think

    1. Let’s just pause to emphasise this point: no amount of R&D, innovation or technology will allow us to remove CO2 from the atmosphere without spending at least 191 kWh per tonne of CO2.

      Even if we acheive perfect efficiency we tax the global economy 10% to remove annual emissions

    1. Table 5.10a. Solar REC prices during the period March 2020 – March  2021 (US$/MWh)

      This are nearly 100x the cost of Hydro RECs in come cases

    1. It should be noted that the third normative approach considers the global need for electricity asoutlined by the International Energy Agency (IEA) for different scenarios and develops an interim1.5DS within which ICT should not expand its current share of electricity. This electricity budgetuses the IEA trajectories for a 2°C scenario (2DS) and a below 2°C scenario (B2DS) to derive a 1.5°Ctrajectory for world electricity usage through doubling the difference between them and subtractingit from the 2DS as described in [IEA ETP]. This is an interim approach as IEA has not yet establisheda 1.5DS. The budget is then used to determine the amount of electricity that could be used by thesector if keeping its share at the current level. As the IEA is planning to include a specific 1.5DS, thetrajectories will be reviewed when the new IEA scenarios are published.

      This is the only mention of a "fair share" of global electricity use by the ICT sector

    1. The VIC system created maintains a list of available URLs or DNS entries for the service requiring computation, each of which live in a different datacenter in a different part of the world. When the service receives a request, it routes that request to the datacenter that best matches the required criteria

      LOL it's DNS again!

    2. A TCP/IP based system was built to investigate the feasibility of a VIC as per Fig. 1. This considers routing Microsoft Azure workloads to datacenters around the world to best satisfy the required criteria. Three criteria were applied: (1) reduce load on a particular electricity grid at peak times, (2) follow green energy and low emissions energy around the world with computation, thus reducing curtailment of renewables and facilitating more renewable energy and (3) take advantage of variable electricity market prices.

      Three criteria reworded:

      (1) reduce peak load on the particular electricity grid (2) reduce fossil generation in the compute (3) reduce cost of electricity use for the compute

    3. Furthermore, many markets grant Capacity Payments to eligible generators and interconnectors for being available to follow dispatch instructions, irrespective of actual generation. VICs would also be eligible to receive such payments but they should be directly to the VICO rather than any users. This allows users to bid without the influence of capacity payments and rewards the datacenters providing the VIC.

      Under this scenario, a grid operator would pay a datacentre to be prepared to switch off local physical load.

      The load would still be served through, albeit on a different grid or grid region where you didn't have the same strains on the electricity network.

    4. Apple, which has a relatively long history of reporting its scope 3 emissions, states in its 2022 Environmental Progress Report that it is actively evolving its scope 3 accounting methodology. “In fiscal year 2017, we started calculating scope 3 emissions not listed above. In fiscal year 2021, these include electricity transmission and distribution losses [...] and life cycle emissions associated with renewable energy. We have not accounted for emissions resulting from employees working from home [...] we are still evolving our methodology.“ Environmental Progress Report (page 84), Apple, 2022
    5. This also explains why, even though Norway’s grid-levelemissions factor is 10 kg CO2/MWh17 (98% carbon-free), the residual

    7. Data demonstrate that many companies do indeed pursue thispractice. For example, Norway was responsible for 43% of allguarantees of origin (GOs) exports in Europe in 2022, many ofwhich were purchased by companies whose operations have noconnection to the Norwegian grid on which these EACs wereproduced.
    1. Wind and solar are, of course, intermittent, but battery costs too are plummeting, to the extent that they often underbid so-called peaking plants burning natural gas

      Where would I look to find public evidence of this?

    1. This article in effect requires local authorities to only use data centres that a fully compliant with the requirements of the specified directives.

      Minimum, mandatory standards for public procurement.

    2. Article 33 Delegated Acts 3. The Commission is empowered to adopt delegated acts in accordance with Article 34 to supplement this Directive by establishing, after having consulted the relevant stakeholders, a common Union scheme for rating the sustainability of data centres located in its territory. The Commission shall adopt the first such delegated act by 31 December 2023. The common Union scheme shall establish the definition of data centre sustainability indicators and shall set out the key performance indicators and the methodology to measure them.

      There's a policy deadline to work - end of this year, so it's likelt there'll be a push to try to weaken it even more.

    3. 5. By 15 May 2025, the Commission shall assess the available data on the energy efficiency of data centres submitted to it pursuant to paragraphs 1 and 3 and shall submit a report to the European Parliament and to the Council, accompanied, where appropriate, by legislative proposals containing further measures to improve energy efficiency, including establishing minimum performance standards and an assessment on the feasibility of transition towards a net-zero emission data centres sector, in close consultation with the relevant stakeholders
    4. . The Commission shall establish a European database on data centres that includes information communicated by the obligated data centres in accordance with paragraph 1. The European database shall be publicly available on an aggregated level.

      It will be law to collect this data now, so we know orgs will have to have it in structured form.

      If it's gonna be in the public domain anyway, there's a good argument for paving a path to make it easy to look transparent, by making it easy to disclose this info in a well presented way human readable way

    5. We think that the threshold for reporting being 500kw is too low, as it will not pick up aggregated edge sites (organisations that have multiple facilties that individually are below the threshold but aggregated would be considerably higher), Mobile Phone basestation sites and Points of Presence (PoPs)

      So ths lobbying will have now effectively hidden 4G/5G infra, as well as a lot of edge

    6. This links back to the lower limit for reporting of 500kw, clearly the EC see no reason to collect data from 'distributed compute' such as individual server rooms (at this time)
    7. This is very interesting, we've seen some national government initatives in various countries relating to the collection of data centre energy data, in the UK we have the Climate Change Agreement for Data Centres which started in 2014 and according to the latest figures (4th Period) indicated that total UK energy use of the period for commercial data centres (colocation sites) was 12TWh. Back to the EED and the very interesting thing is the mention of 'interventions' will this mean the imposition of fines for poor energy performance?
    8. This introduces the requirement for a data centre register and the rating of data centres for sustainabilty, this could become an utter bag of worms, as sustainability is closely linked to the amount of renewable energy systems on an individual country grid, the 'grid mix' and could favour those countries and data centres that are directly linked to low carbon energy sources (Norway, Sweden, Finland (Hydro), France (Nuclear), Spain (Solar/Wind) & Denmark (Wind).

      This also means that though that countries ought to be less keen on selling their EACs though

    1. It’s pretty simple: don’t let carbon removal excuse ongoing or worsening emissions. That means no deal with fossil fuel majors. And if you really must sell carbon credits, here’s my idea: they can only apply to the earliest emissions first. Once we’ve dealt with the ~2,500 ish human-added CO2 gigatonnes in the atmosphere, THEN you can apply credits to new emissions. We go from oldest to newest, not from newest to oldest.

      What about the compounding of warning for these tonnes?

    1. This approach results in our Scope 2 market-based emissions being greater than zero, per the Greenhouse Gas Protocol Scope 2 Guidance, despite us achieving our 100% renewable energy match globally.

      I think is the first time Google has mentioned this in texr that's the same szie as their regular copy.

    2. Electricity purchased from renewable sources (%) is calculated on a calendar-year basis, dividing the volume of renewable electricity (in megawatt-hours) procured for our global operations (i.e., renewable energy procured through our PPA contracts, on-site renewable energy generation, and renewable energy in the electric grids where our facilities are located) by the total volume of electricity consumed by our global operations. This metric includes all renewable energy purchased, regardless of the market in which the renewable energy was consumed

      I read this to mean that they purchase energy for the same calendar year - so usage in 2022 ought to have corresponding environmental attribute certificates for 2022 as well.

      It may be the case that the date of retiring is 2023, because I know that some clodu providers purchase certificates, then sell ones they don't need on the market if they were able to adjust their energy usage to no longer need the same number of cerrtificates.

  14. letsencrypt.org letsencrypt.org
    1. Will Let’s Encrypt issue Organization Validation (OV) or Extended Validation (EV) certificates? We have no plans to issue OV or EV certificates.

      This here is the gap

    1. If the signature over the nonce is valid, and the challenges check out, then the agent identified by the public key is authorized to do certificate management for example.com. We call the key pair the agent used an “authorized key pair” for example.com.

      OK, that's how signing the nonce with the private key helps.. Lets Encrypt already has access to the public key, and so once if has the nonce signed with the private key, it has a way to check the it that the server has both parts of the key pair without needing to see the private key

    1. Reverse proxy implementation in nginx includes in-band (or passive) server health checks. If the response from a particular server fails with an error, nginx will mark this server as failed, and will try to avoid selecting this server for subsequent inbound requests for a while.

      Handy!

    1. Without having to take any risk themselves, they collect increasing profits that are indirectly paid for almost entirely by the European taxpayer. At the current interest rates, this costs the European treasuries 135 billion annually. Dutch banks receive about 11 billion of that sum, of which only 8 billion – 5.8 per cent of total payments – is being borne by Dutch taxpayers. The rest is being paid for by the taxpayers of other European countries, because the interest payments of all central banks within the Eurosystem are mutually settled via a fixed capital key.

      What is a fixed capital key?

    1. WattCarbon decarbonization projects are measured using official government grid data1, site level metered energy data, and open source avoided energy use methodologies2, which provides the highest degree of transparency and integrity for every project on our marketplace.

      This appears to use the open source OpenEEmeter, to figure out a baseline that any interventions would be measured against. This is written in python, so the code can be examined, but it's not obviosu to me how well this would work outside of California

    1. Players confront challenges mirroring those in the real world: they extinguish forest fires, obstruct illegal logging, replant native trees and clean up rivers.

      And destroy mining equipment in the video - amazed an ad agency would let that through

    1. It proved to be so effective that criminalisation spread across Latin America and is now deployed globally as part of a playbook of tactics to divide communities, and detract attention away from legitimate debate and protests about environmental and climate harms.

      Uh, yes, it seems.

    2. Experts say that what happened here helped to establish criminalisation as a go-to tool for polluting industries and governments seeking to discredit and silence activists. Guatemala was a textbook example of a draconian crackdown, becoming a laboratory of sorts, with arbitrary charges used against countless community leaders opposing environmentally destructive projects.

      So this essentially created a playbook for extractive industries to use the law to stifle resistance from local communities?

    1. As plaintiffs’ counsel Nate Bellinger, senior staff attorney at Our Children’s Trust, stated in his closing: “It’s worth remembering other times in our nation’s history when the political process didn’t work to protect people’s basic human rights. Segregation, women’s rights, equal and adequate public schooling, marriage—time and time again, the political will of powerful majorities was struck down by courts, based on the compelling evidence before them, courageously correcting the injustices thrust on the people. Today, the injustice squarely before this Court is the proven harms of these young people wrought by climate change caused by a fossil fuel-based energy system imposed and perpetuated through the law.”

      YES BRUV

    2. But as climate policy analyst Peter Erickson explained during his expert testimony on the plaintiffs’ side, Montana’s total annual CO2 emissions – 166 million tons (based on 2019 data) – are on par with annual emissions of entire countries like the Netherlands and Pakistan. “To call [Montana’s] emissions miniscule is then to call the emissions of over 100 countries of the world miniscule,” Erickson said. “Montana’s emissions matter”, he emphasized.

      Wow, the same as a country with hundreds of millions of people? That seems high

    1. You may have heard of the 3-2-1 backup strategy. It means having at least three copies of your data, two local (on-site) but on different media (read: devices), and at least one copy off-site.

      TIL

    1. The value of provenance information  Adding provenance information to media to combat misinformation is not a new idea, and early research seems to show that it could be promising: one project from a master’s student at the University of Oxford, for example, found evidence that users were less susceptible to misinformation when they had access to provenance information about content.

      How computationally expensive is this to tag content in this way?

    1. They also worked their media mogul pals, like Mike Bloomberg, who added their names to the "Friends of Mike" list that Bloomberg reporters were required to consult before writing negative coverage

      Wow, there’s a friends of Mike?

    1. Full text seach is a way to avoid these two issues. With SQLite, you enable full text search by creating what is called a "virtual table" using one of the FTS engines included with SQLite: FTS4 or FTS5. FTS5 support is the most recent and has more advanced searching features, including ranking and highlighting of results and is what is described here.

      This is the advantage of using FTS5 - it'you get the ranking and highlighting that you might otherwise assocaite with Postgres or other bigger databases that have search capabilities

    1. Let’s dissect this piece of Mojo code. First, you'll notice that we have new variable declarations let and var which may look odd at first glance since this is not familiar Python syntax. Mojo offers optional (except in some cases, more on that later) variable declarations to declare variables as immutable with let (i.e. cannot be modified after creation) or mutable with var (i.e. can be modified).

      this is the opposite of javascript. why not make use 'const'?

    1. P-States

      What is a P-State?

    2. In this example we have run sysbench --cpu-max-prime=25000 --threads=1 --time=10 --test=cpu --events=0 --rate=0 and put a CPU % limiting on the process and increased that in 10% increments. The blue curve has been done with the schedutil CPU frequency govenor which dynamically scales the CPU frequency. And the red curve has been done with the performance scaling govenor which scales the CPU frequency to a maximum as soon as even a minimum amount of load happens on a core.

      In addition to all the stuff above, there are also governors, who decide how a CPU's frequency is scaled in the face of new load being introduced.

    3. Suprisingly we see that on an unloaded system the energy actually increases! The assumption made here is that the cost per instruction goes down. This is an effect that can also be seen in SPECPower benchmarks where the sweet-spot for a system is typically somewhere around the higher third quarter of the peak performance.

      This is weird - basically the energy per instruction is lower under load, because systems are more efficient when they are at around 3/4 peak performance, a bit like a car engine can be more efficient at a specific RPM compared to others

    1. The legislative proposal risks rendering obsolete such ambitious and holistic industry-led initiatives that provide a tool for more informed consumer decisions, encourage improvements by manufacturers and demonstrate European leadership on sustainability questions. The Regulation should instead enable such schemes (which go beyond environmental claims, and consider aspects like durability, recyclability, etc.) to continue being used.

      OK, so this paper is essentially arguing "please use our industry approved way to rate kit, and do not regulate us"

    1. These companies start with people who have the least agency and social power and wreck their lives, then work their way up the privilege gradient, coming for everyone else. It's called the "shitty technology adoption curve":

      "Work your way up the privilege gradient, coming for everyone else." Yeesh

    1. Funneled into the colocation space, this rising demand has almost completely saturated Tier I data center markets like Ashburn, Dallas, and Silicon Valley. As a result, hyperscale workloads are driving growth in Tier II and Tier III markets, occupying existing capacity and spurring new developments.

      I hadn't realised this was such a trend - I was aware the older centralised approaches might not work as well as they used to, but it hadn't occured to me that the hyperscalers were behind the push in the other areas too

    1. New technologies can change who holds power and threaten how things work. Decisions about technology become wrapped up in fights to preserve or change political culture. When thinking about technological changes, we can’t just approach it as a project of modernisation – we need to have a view on the culture we want to create.

      What a quote

    1. As it stands, Intel will walk away with the lion's share of the funding for its Magdeburg megafab, where it plans to produce angstrom-class parts beginning in 2027. After months of negotiations over rising operating and materials costs associated with building in the region – the facility is now expected to cost €30 billion to complete – the x86 titan received commitments from German officials in June for €10 billion in support.

      10bn is about the same as the 9 euro ticket would have cost for all of 2023

    1. Storage –Increasing solar penetration causes the number of high-load hours (within 5% of peak) to decline from seven hours in the Base scenario to just two hours in the Accelerated scenario.

      More solar on roofs means the number of high loads hours is 3 times smaller

    1. Decarbonize Alibaba (Scopes 1 and 2): By 2030, we will achieve carbon neutrality in our own operations.Green the value chain (Scope 3): By 2030, we will collaborate with our upstream and downstream value chain partners to cut emission intensity by 50% from the base year of 2020. Alibaba Cloud will achieve Scope 3 carbon neutrality during the same period.Enable a low-carbon circular digital ecosystem (Scope 3+): Beyond our own operations and direct value chains, we pledge to leverage our digital platforms to encourage even broader participation by stakeholders that can be reached by our efforts. By 2035, we will facilitate 1.5 gigatons of GHG emission reduction over 15 years across Alibaba's digital ecosystem.

      These are the three high level commitments.

      Carbon neutrality, which is as close to Net Zero as I can find, but they include "Scope 3+".

      This isn't a term in the GHG Protocol lexicon that I know of.

    1. In 2021, Alibaba set ambitious targets of achieving carbon neutrality in our own operations and halving the energy intensity across our value chain by 2030 and driving emission reduction of 1.5 gigatons over 15 years in our platform ecosystem

      There's a 2030 end goal target

    1. Not that an E2E rule precludes algorithmic feeds: remember, E2E is the idea that you see what you ask to see. If a user opts into a feed that promotes content that they haven't subscribed to at the expense of the things they explicitly asked to see, that's their choice. But it's not a choice that social media services reliably offer, which is how they are able to extract ransom payments from publishers.

      I don't understand how you could audit this, unless you had to force a default of chronological presentation of posts etc.

    2. This is nonsense: when users are given the choice to block surveillance, they overwhelmingly do. Apple's iOS devices offer users a one-click opt-out from app-based surveillance. Ninety-six percent of iOS users have opted out (presumably the other four percent were confused — or on Meta's payroll).

    1. First and foremost, where will a largely desert country source the water for electrolysis? Secondly, will Namibia export only hydrogen, ammonia, or some of the industrial products made with the green inputs? It would be advantageous for Namibia to develop a heavy-chemicals and iron-smelting industry. But from Germany’s point of view, that might well defeat the object, which is precisely to provide affordable green energy with which to keep industrial jobs in Europe.

      This is an interesting point - shipping the gas vs shipping the higher value products enabled by the gas

    1. The Lyubchyks estimate that the levelised cost of energy – the average net present cost of electricity generation for a generator over its lifetime – from these devices will indeed be high at first, but by moving into mass production, they hope to lower it significantly, ultimately making this hygroelectric power competitive with solar and wind. For that to work, though, they’ll need investment, access to raw materials and the equipment to process them.

      How high?

    2. They’ve come a long way since then, with Catcher and related projects receiving nearly €5.5m (£4.7m) in funding from the European Innovation Council. The result is a thin grey disc measuring 4cm (1.5in) across. According to the Lyubchyks, one of these devices can generate a relatively modest 1.5 volts and 10 milliamps. However, 20,000 of them stacked into a washing machine-sized cube, they say, could generate 10 kilowatt hours of energy a day – roughly the consumption of an average UK household. Even more impressive: they plan to have a prototype ready for demonstration in 2024.

      Waaaaaaaaat

    1. The arrangement will see Contact provide Microsoft with all the renewable energy attributes generated by Contact’s new 51.4MW Te Huka Unit 3 geothermal power station.

      But not all the power?

    1. Tonne-for-tonne offsetting has historically relied upon the cheapest possible carbon credits that do little to benefit the climate and represent no real pollution cost for companies. Polluters should move to money-for-tonne contributions instead, based on an internal carbon price (WWF recommends $50-250), which would encourage the purchase of higher quality carbon credits with co-benefits. The internal carbon price in turn could be proportional to companies’ revenues or profits. 

      Buying carbon credits with co-benefits, not offsets
