SQLite's documentation about its durability properties is unclear

news.ycombinator.com Andrew Ayer 2025-10-20 14:30:29

One of the most important properties of a database is durability. Durability means that after a transaction commits, you can be confident that, absent catastrophic hardware failure, the changes made by the commit won't be lost. This should remain true even if the operating system crashes or the system loses power soon after the commit. On Linux, and most other Unix operating systems, durability is ensured by calling the fsync system call at the right time. Durability comes at a performance cost

Income Equality in Nordic Countries: Myths, Facts, and Lessons

news.ycombinator.com Mogstad 2025-10-21 16:03:33

Abstract Policymakers, public commentators, and researchers often cite the Nordic countries as examples of a socioeconomic model that combines low income inequality with prosperity and growth. This article critically assesses that claim by integrating theoretical perspectives and empirical evidence to explain how the Nordic model functions and why these countries experience low inequality. Our analysis suggests that income equality in the Nordics is largely driven by a significant compression of

This ‘Magical’ Material That Dissolves Like Candy Is Exactly What EVs Have Been Missing

gizmodo.com Gayoung Lee 2025-10-22 00:40:05

The irony of eco-friendly electric vehicles is the mountainous load of electronic waste they produce. So far, most targeted efforts to recycle EV batteries have been expensive and chemically toxic—and they haven’t stuck. That could change soon, however, thanks to a promising breakthrough from MIT. In a Nature Chemistry paper published August 28, researchers describe a new type of self-assembling material that easily dissolves in organic solvents.

Qualcomm’s next Elite processor could have a ridiculously confusing name

androidauthority.com Unknown 2025-10-22 22:02:12

C. Scott Brown / Android Authority TL;DR A leaker has claimed that the next Snapdragon 8 Elite chip could be called the Snapdragon 8 Elite Gen 5. This is a major departure from the expected Snapdragon 8 Elite 2 or 8 Elite Gen 2 names. We’re guessing this is because Qualcomm is readying an apparent Snapdragon 8 Gen 5 chip as well. Qualcomm launched the Snapdragon 8 Elite late last year, and this represented a change in naming convention after the Snapdragon 8 Gen 3. We were expecting the Snap

You know what’s wrong with people? They’re too sure of themselves. Better to be wrong and own it than be right with caveats. Hard to build a personal brand out of nuance these days. People are attracted to confidence — however misplaced. But can you blame them? (People, that is) Working in software, the most annoying part of reaching Senior level is having to say “it depends” all the time. Much more fun getting to say “let’s ship it and iterate” as Staff or “that won’t scale” as a Principal.

Satellite Companies Like SpaceX Are Ignoring Astronomers’ Calls to Save the Night Sky

There are more than 12,000 active satellites circling Earth at the moment, a growing figure that has nearly doubled in less than three years. This recent boom in the satellite industry has been a major headache for astronomers, with bright satellites appearing as streaks in telescope images of the universe and tarnishing views of the night skies.

But in 2019, SpaceX began deploying its internet-beaming Starlink constellation, and the astronomical community started to sound alarm bells. The satellites were orbiting too low and reflected too much sunlight, leaving bright marks in telescope images. A year later, Rawls and a handful of her colleagues were the first to make a scientific assessment of the satellite streaks’ effect on astronomical observations, using images from the Víctor M.
