Firefox 32-bit Linux Support to End in 2026

news.ycombinator.com Julien Cristau 2025-10-02 17:07:07

For many years, Mozilla has continued to provide Firefox for 32-bit Linux systems long after most other browsers and operating systems ended support. We made this choice because we care deeply about keeping Firefox available to as many people as possible, helping our users extend the life of their hardware and reduce unnecessary obsolescence. Today, however, 32-bit Linux (on x86) is no longer widely supported by the vast majority of Linux distributions, and maintaining Firefox on this platform

Mathematical secrets of ancient tablet unlocked after nearly a century of study (2017)

At least 1,000 years before the Greek mathematician Pythagoras looked at a right angled triangle and worked out that the square of the longest side is always equal to the sum of the squares of the other two, an unknown Babylonian genius took a clay tablet and a reed pen and marked out not just the same theorem, but a series of trigonometry tables which scientists claim are more accurate than any available today.

Court Records Reveal Sig Sauer Knew of Pistol Risks for Years

A court exhibit recently published online summarizes Sig Sauer’s internal P320 testing and shows that the gun maker and U.S. Army were both aware of serious safety risks with the pistol since at least 2017, years before it was fielded to soldiers as the full-size M17 and compact M18. The document — prepared as a part of Sig Sauer’s contracting process with the U.S. Army — outlines multiple ways the pistol could fire without an intentional trigger pull.

Faster substring search with SIMD in Zig

Faster substring search with SIMD in Zig I’ve been learning a lot about low-level programming languages lately, and for a long time there has been one thing that has interested me: SIMD (or ‘single instruction, multiple data’) code. I’ve seen a lot of articles about having massive performance gains by utilizing SIMD and wanted to learn how to do it myself. This article is a journey into implementing ~60% faster substring searching compared to Zig’s std.mem.indexOf using a SIMD-friendly algorit

Efficiently Generating a Number in a Range (2018)

news.ycombinator.com M.E. O'Neill 2025-12-06 05:38:14

The vast majority of my posts about random number generation have focused on looking at the properties of different generation schemes. But, perhaps surprisingly, the performance of your randomized algorithm may hinge not on the generation scheme you chose, but on other factors. In this post (inspired by and building on an excellent recent paper by Daniel Lemire), we'll explore a common source of overhead in random number generation that frequently outweighs PRNG engine performance.

Debian plots fix for Y2K38 bug by upgrading to 64-bit timekeeping

techspot.com Alfonso Maruccia 2025-12-20 03:13:00

The big picture: On January 19, 2038, at 03:14:07 UTC, certain Unix-based computer systems will encounter a critical timekeeping failure. Due to a software flaw known as the "Y2K38 bug," 32-bit Unix-like operating systems will reset their internal clocks to the start of the Unix epoch – January 1, 1970 – and begin counting time from there again. While the consequences could be widespread, developers are already working on fixes to ensure systems continue to track time correctly. The Year 2038 p

Venerable Linux distribution Debian is side-stepping the Y2K38 bug – also known as the Unix Epochalypse – by switching to 64-bit time for everything but the oldest of supported hardware, starting with the upcoming Debian 13 "Trixie" release. "[We will] use 64-bit time_t on 32-bit architectures to avoid the 'year 2038 problem' when the existing 32-bit signed int rolls over (potentially setting time back to 1900)," the Debian maintainers say of the move and the problem it aims to fix.

Breaking the WASM/JS communication performance barrier

news.ycombinator.com Unknown 2025-12-17 10:11:31

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline

Properly seeding random number generators doesn't always get the attention it deserves. Quite often, people do a terrible job, supplying low-quality seed data (such as the system time or process id) or combining multiple poor sources in a half-baked way. C++11 provides std::seed_seq as a way to encourage the use of better seeds, but if you haven't thought about what's really going on when you use it, you may be in for a few surprises.
