    1. This is a very dangerous practice as each optimization means making assumptions. If you are compressing an image you make an assumption that some payload can be cut out without seriously affecting the quality, if you are adding a cache to your backend you assume that the API will return same results. A correct assumption allows you to spare resources. A false assumption introduces a bug in your app. That’s why optimizations should be done consciously.
    2. In the vast majority of cases there’s nothing wrong about wasted renders. They take so little resources that it is simply undetectable for a human eye. In fact, comparing each component’s props to its previous props shallowly (I’m not even talking about deeply) can be more resource extensive then simply re-rendering the entire subtree.

    1. Forwarding events from the native element through the wrapper element comes with a cost, so to avoid adding extra event handlers only a few are forwarded. For all elements except <br> and <hr>, on:focus, on:blur, on:keypress, and on:click are forwarded. For audio and video, on:pause and on:play are also forwarded.

    1. Even having useCallback() returning the same function instance, it doesn’t bring any benefits because the optimization costs more than not having the optimization.

    1. The deceitful obfuscation of commercial intention certainly runs all the way through the data brokering and ad tech industries that sit behind much of the ‘free’ consumer Internet. Here consumers have plainly been kept in the dark so they cannot see and object to how their personal information is being handed around, sliced and diced, and used to try to manipulate them.
    1. Yes, it’s been deprecated. Why? Because too few people were using it to make it worth the time, money, and energy to maintain. In truth, although I sometimes disagree with the operator changes, I happen to agree with this one. Maintaining ALL of the synonyms takes real time and costs us real money. Supporting this operator also increases the complexity of the code base. By dropping support for it we can free up a bunch of resources that can be used for other, more globally powerful changes.

    1. Hans Moravec argued in 1976 that computers were still millions of times too weak to exhibit intelligence. He suggested an analogy: artificial intelligence requires computer power in the same way that aircraft require horsepower. Below a certain threshold, it's impossible, but, as power increases, eventually it could become easy.[79] With regard to computer vision, Moravec estimated that simply matching the edge and motion detection capabilities of human retina in real time would require a general-purpose computer capable of 109 operations/second (1000 MIPS).[80] As of 2011, practical computer vision applications require 10,000 to 1,000,000 MIPS. By comparison, the fastest supercomputer in 1976, Cray-1 (retailing at $5 million to $8 million), was only capable of around 80 to 130 MIPS, and a typical desktop computer at the time achieved less than 1 MIPS.
    1. Times have changed and today various mobile technologies have enabled startups, SMBs and enterprises to build an app in their budget. Here is an article from explaining current app development processes and costs.

    1. To submit a proposal, a user must bond a set num-ber of Audius tokens (denotedBGP) in the governancesystem, which remain bonded for the duration of theirproposal. Before a proposal's e ective date, the origi-nal submitter can also choose to withdraw the proposalif they so choose, returning their bonded tokens. Thisbond is required as an anti-spam measure and to ensurethat proposers to have a sucient stake in the Audiusprotocol to make changes to it. At the proposal's res-olution (successful, failed, or withdrawn), the bond isreturned to proposal submitter.

    1. The Ferguson Police are told to bring in as much revenue as possible, those that fail to bring in enough revenue are assigned to different positions or receive discipline.

    1. A prolonged walkout can quickly take a financial toll on car companies because they book revenue only when a vehicle is shipped to a dealership. An assembly-plant shutdown can cost an auto maker an estimated $1.3 million every hour, according to the Center for Automotive Research in Ann Arbor, Mich.
    1. But sustained Saudi outage of several million daily barrels would rattle markets, because of the lack of other players big enough to step in and provide enough supply to cover the shortfall longer term. Even if Saudi officials were successful in restoring all or most of the lost production, the attack demonstrates a new vulnerability to supply lines across the oil-rich Gulf. Tankers have been paying sharply higher insurance premiums, while shipping rates have soared in the region after a series of maritime attacks on oil-laden vessels, which the U.S. has blamed on Iran.

    1. Due to its electrical conductivity, copper is used in electronics, cars, and wires. This makes copper critical for highly developed countries.

      true stuuff

    2. Codelco is a state-owned Chilean mining company and the world’s largest copper producer. Based on their annual report and USGS statistics, they produced ~10% of the world’s copper in 2015 and own 8% of global reserves. They are also a large producer of greenhouse gas emissions. Last year, Codelco produced 3,2 t CO2e/millions tmf from both indirect and direct effects, and in 2011 it consumed 12% of the total national electricity supply.

      Goddamn they should start recylcling

    3. What can Codelco do, then? In addition to cost cutting, Codelco could consider entering the recycling copper industry, as energy prices are driving “virgin” copper costs up.

      thats good

    4. copper mining significantly contributes to climate change.

    1. Most health care programmes in place are designed to fund only a limited intensity of post-acute care, hence households might end up facing significant costs to fund long-term care in the absence of public support, which might end up impoverishing them and eventually even bankrupting them

      The impact on overall household cost accrual should not be overlooked as the implications on already financially disenfranchised groups would impose compounded disadvantage. This 2018 survey conducted by Carescout covered 440 regions and included 15,500 individual surveys which estimate the median cost of adult day care at $18,720. median cost of assisted living at $48,000, and the median cost of nursing home care at $89,297 annually (https://www.genworth.com/aging-and-you/finances/cost-of-care.html) further contextualizing the overwhelming burden of absorbing long term health cost in the absence of public funding

    2. Kim and Norton (2017) find in the context of the Medicare prospective payment system in the US that for-profit agencies are more responsive than not-for-profit agencies to financial incentives, and therefore contribute disproportionately to the increase in Medicare home health spending under the prospective payment system.

      Effectively targeting exploration on the topic of not-for-profit responsiveness may help mediate the disparate costs associated with home health care. The impact of new technologies should be considered when assessing the ability of these organizations to respond. Saxton, Guo, & Brown (2007) found that limitations in design and content availability profoundly affected the responsiveness of non-profit organizations. These structural barriers should be evaluated by providers to enhance financial sustainability.

    3. The policy implications suggest that community services ought to be prioritised, and if cash subsidies are considered they ought to be made conditional on being used on long-term care without substituting pre-existing support

      What we may find through the introduction of conditional subsidies is the impact of cash allowances for mitigating overall household costs in a households with lower socioeconomic statuses. However, varying configurations in the implementation of cash for care models have been shaped by timing, specific regulations and policy context of reforms in European countries currently utilizing these approaches (Roit & Bihan, 2010). This informs perspectives on the generalizability of subsidization outcomes.

    4. One of the particular features affecting the financial sustainability of a publicly funded system is the extent of public subsidisation of informal care.

      The subsidisation of informal care has brought with it ongoing debate on both the efficacy and impact for individuals with varying needs of ADL support. In a study conducted by Kim and Lim (2012) findings suggest that institutional care is most cost-effective for individuals partially-dependent on support for several ADL's in that it led to reduction of informal care and medical expenditures whereas cost benefits for home care were higher among individuals that were completely dependent on ADL support through reduced spending on institutional support. Overall a shift from formal care to informal home care seems to be placated here as a financial target for sustainability.

    1. provisions in the Proposed Rule that would advance these goals. Examples include proposals that would give states more flexibility in designing network adequacy standards that best meet the needs of enrollees, and give states implementingmanaged care programs the option to continue “pass-through

      In the examples provided Matthew Eyles provides a thoughtful consideration of the possible ways enacting these provisions could work to the benefit of patients. The network changes applauded are largely person centered and in the aim of service delivery and access.

    2. Health plans know that Medicaid needs to work for people who rely on it –and the hardworking taxpayers who pay for it.Studies show that the vast majority of Medicaid enrollees have regular access to care and that they are satisfied with their care.1Medicaid health plans focus on detecting and preventing the progression of chronic diseases, coordinating services across the continuum of care, and delivering programs targeted to individual needs

      Operating loosely from the coordinated specialty care approach the ability of managed care plans to secure services for patients across their diverse needs is a central to the quality of public health and underscores the impact that removing such ability would have on the public at large.

    3. Most notably, we are concernedabout proposedtechnical changes in federal rate-setting standards that would be inconsistent with statutory actuarial soundness requirementswhichensure that payments to Medicaid managed care plans are reasonable and appropriate

      This statement seems to hint at the likelihood that proposals would undermine the efficacy of medicaid to secure services and maintain financial viability over time of implementation. As mentioned by AEH (Americas Essential Hospitals) most organization are operating on little to no profit margin: https://essentialhospitals.org/general/statement-on-house-reconciliation-legislation/ which means that cuts such as these could result in reductions to staff and hospital services overall.

    1. will have the net effect of shifting health insurance costs to low and middle-income patients, significantly reduce the standards of what constitutes quality insurance, curtail the Medicaid expansion and over time substantially reduce over-all Medicaid funding.

      The erosion of medicaid program coverage is what we can see in the horizon under these shifts. Reductions in standards of care, quality assurance and government accountability for public health will inevitable lead to the negligence of service availability for low income and high risk populations. The benefit of these changes will be seen mainly among private interest sectors that have customarily re allocated funds from safety net programs into state budget spending.

    2. Moreover, reduced federal funding combined with state-specific eligibility and enrollment restrictions will likely result in fewer cancer patients accessing needed health care. For low-income individuals these changes could be the difference between an early diagnosis when outcomes are better and costs are less or a late diagnosis where costs are higher and survival less likely.

      Reducing availability of funds for individuals needing treatment adds overwhelming weight to the public health crisis and early intervention leads to reduced health costs and improved overall outcomes. For minority populations these changes could present compounded risk due to already existing disparities in treatment : https://www.cancer.gov/about-nci/legislative/hearings/2000-ethnic-minority-disparities-cancer-treatment.pdf as black americans already face higher rates of overall incidence of cancer and higher rates of death than their white counterparts.

    3. In 2015, approximately 1.5 million people with a history of cancer between 18-64 years old relied on Medicaid for their insurance.  Nearly one-third of childhood cancer patients are insured through Medicaid at the time of diagnosis.

      The implications of lesser coverage would be vast particularly for children insured through medicaid during their time of diagnosis. These individuals may face additional risk to their healthcare assess due to changes in regulatory protections currently being proposed (i.e. protections for pre-existing conditions).

    1. 2003 amid the push for quality and safety. And while the specialty’s early adoption of those initiatives clearly was a major reason for the exponential growth of hospitalists, Dr. Gorman doesn’t want people to forget that the cost of care was what motivated community facilities.
    1. First, because of cost pressures,managed-care organizations will reward profession-als who can provide efficient care. In the outpatientsetting, the premium on efficiency requires that thephysician provide care for a large panel of patientsand be available in the office to see them promptlyas required. There is no greater barrier to efficiencyTin outpatient care than the need to go across thestreet (or even worse, across town) to the hospital tosee an unpredictable number of inpatients, some-times several times a day. There are parallel pressuresfor efficiency in the hospital. Since the inpatient set-ting involves the most intensive use of resources, itis the place where the ability to respond quickly tochanges in a patient’s condition and to use resourcesjudiciously will be most highly valued. This shouldprove to be the hospitalists’ forte.
    1. Koh et al. (11) detailed a cycle of crisis care elaborating the nature of high medical costs, possibly resulting from fear and denial. First, an individual is in need of medical help, so he or she goes to a physician's office where the staff asks the individual to fill out a complex and confusing form. The physician examines the patient and explains the condition and treatment options using medical jargon. Numerous prescriptions, laboratory tests, and referrals are given without confirmation of the patient's comprehension. The staff sends the patient home with complicated instructions. Inevitably, the patient may consume medication incorrectly or miss follow-up appointments, and his or her condition worsens. Eventually, the patient presents to the emergency department, and the hospital staff develops a new treatment plan. Again, no one confirms the patient's understanding. When the patient is discharged, he or she is likely to get sick again and repeat the cycle (11)

    1. So & Doering (2016) reports that 75% of 1500 students at the University of British Columbia said they had gone without purchasing a textbook for at least one course. The research on cost reveals that the price of commercial textbooks is affecting students not just financially, but also in terms of their learning.
    2. Jhangiani & Jhangiani (2017) report that of over 300 students in British Columbia, 54% said they had not bought a textbook for a course at least once due to cost, 27% said they had taken fewer courses, 26% said they did not register for a particular course because of the cost of the book(s), and 17% said they had dropped or withdrawn from a course.

      Of course they do - but benefits like this cost money. Publishers run businesses; businesses need profits 2 keep shareholders happy. But, so far, the platforms make learning more costly for students.

    1. On the cost rejected papers add to the peer review system (p. 119): "The cost to the academic community of refereeing was estimated by Tenopir and King in 1997 to be $480/article (based on an average time 3–6 hours per article by each of 2–3 referees). At 2004 levels this is approximately $540 per submitted article. Clearly,the percentage ofpapers which are rejected makes a difference to the over- all cost to the journal; in a reasonable quality journal at least 50% of papers will be rejected, while some top journals (e.g. Nature) may reject as many as 90%. Most articles get published somewhere, and as they work their way through the system, being refereed for different journals, they accumulate additional cost; indeed, it couldbe said that a poor (or, at least, inappropriately submitted) article costs the system much more overall than does a good one."

    1. This article included an estimate from the system that further backs up the $530 – $640 figures. [Hanley’s] rough estimate: As of a few years ago, learners at the 23-campus, 460,200-student university system were spending $300 million a year on course materials — about $651 per student per school year.

      This graph is the kicker. It is NOT about textbook costs, it's about how much students can afford to spend. The amount hasn't changed, or has gone down, since '02!

    1. If we can’t keep raising costs for students (we can’t) and if no one is coming to save us (they aren’t), then the only remaining way to help these students is to make a cheaper version of higher education for the new student majority.
