about half of the posts containing LLM-generated comments were deleted for unknown reasons. “It’s very weird to have basically half of your data go missing after the treatment,” Altay says. “It really prevents causal inference.”

A fully isolated virtual machine means Phoenix.new’s fingernails can get arbitrarily dirty. If it wants to add a package to mix.exs, it can do that and then run mix phx.server or mix test and check the output. Sure. Every agent can do that. But if it wants to add an APT package to the base operating system, it can do that too, and make sure it worked. It owns the whole environment.

This offloads a huge amount of tedious, repetitive work.

At this distance the strain is roughly h≈ 10−5. That means that the structures of the inner ear that are maybe a few millimetres large would move by something in the order of a few tens of nanometres. Not much, but given that apparently our ears can pick up displacements of the ear drum of mere picometres that's probably perfectly audible!

fiat prices would also be super high

Also lovely to see that initial graph, almost a validation of Greater Male Variability hypothesis right there.

In a 1992 paper titled "Variability: A Pernicious Hypothesis", Stanford Professor Nel Noddings discussed the social history which she argued explains "the revulsion with which many feminists react to the variability hypothesis."[40]

In 2005, then Harvard President, Larry Summers, addressed the National Bureau of Economic Research Conference on the subject of gender diversity in the science and engineering professions, saying: "It does appear that on many, many different human attributes—height, weight, propensity for criminality, overall IQ, mathematical ability, scientific ability—there is relatively clear evidence that whatever the difference in means—which can be debated—there is a difference in the standard deviation, and variability of a male and a female population."[41][42] His remarks caused a backlash; Summers faced a no-confidence vote from the Harvard faculty, prompting his resignation as President.[43][44]

In 2017, a mathematics research paper by Theodore P. Hill and Sergei Tabachnikov, presenting a possible evolutionary explanation for the variability hypothesis, was peer-reviewed, accepted, and formally published in The New York Journal of Mathematics. Three days later, that article was removed and replaced by an unrelated article by different authors.[45] This caused debate within the scientific community and international publicity.[46][47][48] A revised version was subsequently peer reviewed again and published in the Journal of Interdisciplinary Mathematics.[49]

Sarah's secret weapon? She batches all meetings after 2 PM and uses morning hours when her cognitive load is lowest.

Marcus discovered that starting before his team's online eliminates external interruptions entirely.

Priya's insight: she noticed her energy naturally peaks in early afternoon, so she optimized her schedule around her biological rhythm.

David's rule: only work on tasks that require genuine problem-solving during this window—no routine maintenance or code reviews.

Alex Thompson, "I learned this from a senior dev mentor: protect your best hours like your salary depends on it—because it does. I use this time for feature development exclusively. Everything else gets relegated to my 'shallow work' hours."

larger companies responded by offshoring R&D to countries with more favorable tax regimes, leading to U.S. job losses. For example, Google reportedly shifted some work to Germany, and Microsoft moved a bunch of research work to China - both because pay rates were better and because the local subsidiary company in that jurisdiction operated under the national laws for that nation, which … were not the US tax laws. They were much more like the previous US tax laws, because the rest of the world had realized “hey, we also want to encourage people to invest in R&D and grow the next trillion dollar company here!” And this new tax ruling doesn’t precisely say “we don’t want to do that” but it does say “we don’t want you to be quick about it” - which everyone who believes in the Amazing Growth Story thinks is anathema to their strategy.

Anyway, the impact of this tax strategy turned out to be: layoffs of U.S.-based engineers while companies restructured operations abroad.

Regenerative braking recovers energy while slowing down.

“Psychology like mine prepares for an end or even for the end. The question is only, what are we going to kill: ourselves or our still infantile psychology and its appalling unconsciousness.”

The fix: From O(N²) to efficient mapping

To resolve this performance issue, we contributed an upstream fix to Git that replaces the nested loops with a map data structure. Each reference is added to the map, which automatically ensures only a single copy of each reference is retained for processing.

This change dramatically enhances the performance of git bundle create and enables much better scalability in repositories with large reference counts. Benchmark testing on a repository with 10,000 references demonstrates a 6x performance improvement.

For some features, vibe coding also simply does not feel responsible. For example, when dealing with money. While the UI of the eCash wallet was largely vibe coded in Chorus, Calle coded most of the actual Cashu implementation by hand to be sure that he knew and could trust that the user's money would be safe with us. However, Jack did also vibe code a working Cashu implementation with Goose — proving that it’s not impossible, just dangerous.
