these guys are lemurs 00:19:09 taking hits off of centipedes so they bite centipedes literally get high and they go into these trance-like states I'm sure this is not at all familiar to anyone here 00:19:24 um they get super cuddly uh and then later wake up and go their way but they are seeking a kind of transcendent State of Consciousness Apes will spin they will hang on Vines and spin to get dizzy 00:19:37 and then Dolphins will intentionally inflate puffer fish to get high pass them around in the ultimate puff puff pass right many mammals seek a Transcendent 00:19:57 altered state of being and if they communicate they may well communicate about it

In addition to their high GHG emissions from consumption, high-SES people have disproportionate climate influence through at least four non-consumer roles: as investors, as role models within their social networks and for others who observe their choices, as participants in organizations and as citizens seeking to influence public policies or corporate behaviour

We focus on individuals and households with high socioeconomic status (SES; henceforth, high-SES people) because they have generated many of the problems of fossil fuel dependence that affect the rest of humanity.

people who are wealthy contribute the most to causing climate change, they are unfortunately also in the most ideal position to help us mitigate climate change.

Introduced in September 2017, macOS 10.13 High Sierra brought new updates to the Photos and Safari apps. However, most of the changes happened underneath, including performance improvements and technical updates.

They also highlighted that high emitters live in all countries, but were concentrated in the USA (3.16 million), causing an average 318 t CO2-e per person, Luxemburg (10,000 individuals emitting 287 t CO2-e/year each), Singapore (50,000, 251 t CO2-e/year), Saudi Arabia (290,000, 247 t CO2-e/year), and Canada (350,000, 204 t CO2-e/year)

The long-term goal of public health is to reduce suicide

Wyoming has been aptly characterized as “a small town with very long streets.”

High Country News, Rebecca Nagle reported that for every dollar the U.S. government spent on eradicating Native languages in past centuries, it has spent less than 7 cents on revitalizing them in the 21st century. 

Mirriam also struggled as an adult English learner. A Spanish language teacher and the owner of a Spanish language school for school-age children, Mirriam immigrated to Oregon after completing two years of college in Mexico.

After the first week of the campaign, we realized what are the main problematic pillars and fixed them right away. Nevertheless, even with these improvements and strong support from the Gamefound team, we’re not even close to achieving the backer numbers with which we could safely promise to create a game of the quality we think it deserves.

Consider another example—education. It is true that in most countries, asin the United States, a higher level of educational attainment is typically as-sociated with a lower risk of economic insecurity. But the penalties associatedwith low levels of educational attainment, and the rewards associated with highlevels of attainment, vary significantly by country. Full-time workers without ahigh school degree in Finland, for instance, report the same earnings as thosewith a high school degree. In the United States, however, these workers ex-perience a 24 percent earnings penalty for not completing high school.23 InNorway, a college degree yields only a 20 percent earnings increase over a highschool degree for full-time workers, versus a much higher 68 percent increase inthe United States.24 The percentage of those with a high school degree earningat or below the poverty threshold is more than 4 times higher in the UnitedStates than in Belgium.25

High-poverty neighborhoods arefrequently defined as census tracts in which 40 percent or more of the residentsare living below the poverty line.6

Yes, precisely because I've been involved in maintaining codebases built without real full stack frameworks is why I say what I said.The problem we have in this industry, is that somebody reads these blog posts, and the next day at work they ditch the "legacy rails" and starts rewriting the monolith in sveltekit/nextjs/whatever because that's what he/she has been told is the modern way to do full stack.No need to say those engineers will quit 1 year later after they realize the mess they've created with their lightweight and simple modern framework.I've seen this too many times already.It is not about gatekeeping. It is about engineers being humble and assume it is very likely that their code is very unlikely to be better tested, documented, cohesive and maintained than what you're given in the real full stack frameworks.Of course you can build anything even in assembler if you want. The question is if that's the most useful thing to do with your company's money.
