Hacker News’ monthly “Who’s Hiring?” thread for January 2026 is live, bringing its usual low-friction, high-signal pulse check on real engineering needs. What’s notable here is the format: hiring managers and founders post directly with concrete details like role, location, remote policy, and application links-without recruiter detours or

If 2019 was the prelude, 2020 made mirrorless the default. Canon’s EOS R5/R6 pushed the RF system into true flagship territory with IBIS, deep-learning subject detection, and-yes-headline-grabbing 8K RAW (with thermal constraints clearly in play). Sony finally delivered the video workhorse creators wanted in the A7S III: 4K/

Finnish authorities have detained a vessel and its crew following damage to a critical undersea cable-an uncommon enforcement step that puts a spotlight on the physical risks underpinning global connectivity. Under the hood, operators detected the fault the standard way: sharp optical power loss and reflectometry pinpointing a break location,

For Python performance, a few implementation constants matter more than micro-bench hot takes. Under the hood, CPython’s Global Interpreter Lock switches threads roughly every 5 ms (sys.getswitchinterval), so thread-based concurrency is bounded by that cadence unless C extensions release the GIL. Lists grow by about 12.5% when

“Linux is good now” isn’t a meme so much as a convergence report. What’s notable here is the stack has quietly matured end-to-end: Wayland is the default in GNOME and KDE, PipeWire unifies pro audio and video routing, and driver support (including NVIDIA’s improved Wayland/GBM path

A new video titled “Bluetooth Headphone Jacking: A Key to Your Phone” demonstrates how a simple Bluetooth accessory can effectively function as a de facto key to a smartphone. What’s notable here isn’t a flashy kernel exploit, but the quiet abuse of convenience features that treat nearby Bluetooth

Reports of pop-up blocking being “over” miss the technical nuance. Modern browsers still block unsolicited windows by default; what’s notable here is that more pop-ups are now riding on legitimate user gestures. Under the hood, Chrome, Firefox, and Safari tie window-opening to a transient “user activation” token (e.g.

I canceled my book deal. What’s notable here isn’t the drama; it’s the economics and control. Under the hood, traditional contracts often bundle print, ebook, and audio rights, set pricing windows, and tie timelines to multi-quarter publishing calendars. Cancelling reverts leverage: I can ship on my schedule,

An “efficient” method to pull CO2 from ambient air only matters if it moves the hard numbers. What’s notable here isn’t the headline claim but the knobs that set real performance: total energy per ton at ~420 ppm, sorbent lifetime and replacement cost, air-side pressure drop, and the

A Show HN project packages a large swath of Hacker News into a 22 GB SQLite database, turning the site’s history into a single-file dataset you can query locally. What’s notable here isn’t just the volume, but the format: SQLite means zero setup, no API rate limits,
