Today’s Top 10 on Hacker News
1. A recent experience with ChatGPT 5.5 Pro
⭐ 332 💬 186 👤 alternator 🔗 Discuss on HN
I have just made a fairly large revision as a result of ChatGPT 5.5 Pro, to which I am fortunate to have been given access, producing a piece of PhD-level research in an hour or so, with no serious mathematical input from me. The background is that, as has been widely reported, LLMs are now capable of solving research-level problems, and have managed to solve several of the Erdős problems listed on [Thomas Bloom’s wonderful…
2. Google broke reCAPTCHA for de-googled Android users
⭐ 1075 💬 371 👤 anonymousiam 🔗 Discuss on HN
The requirement forces Android users to run Google’s proprietary app framework version 25.41.30 or higher just to prove they’re human. When reCAPTCHA flags what it considers suspicious activity, it abandons the old image puzzles and demands you scan a QR code. That scan requires Play Services running in the background, communicating with Google’s servers.
3. Using Claude Code: The unreasonable effectiveness of HTML
⭐ 163 💬 89 👤 pretext 🔗 Discuss on HN
Thariq (@trq212) shares how Claude Code is particularly effective at generating and iterating on HTML, a format that AI models understand well. The post has generated significant discussion on X with over 8,000 likes, 1,800 reposts, and 15,900+ bookmarks, suggesting broad community interest in using AI coding agents for web development tasks.
4. OpenAI’s WebRTC problem
⭐ 333 💬 83 👤 atgctg 🔗 Discuss on HN
A former WebRTC engineer from Twitch and Discord argues that WebRTC is fundamentally the wrong protocol for voice AI applications. WebRTC aggressively drops audio packets to keep latency low, which degrades prompt accuracy — the opposite of what you want when paying for expensive LLM inference. The protocol’s design for real-time conferencing (no retransmission, small jitter buffers) works against AI voice agents where accuracy matters more than speed. The author advocates for Media over QUIC as a better alternative.
5. Mythical Man Month
⭐ 169 💬 115 👤 ingve 🔗 Discuss on HN
After it was done he penned his thoughts in the book The Mythical Man-Month which became one of the most influential books on software development after its publication in 1975. Reading it in 2026, we’ll find some of it outdated, but it also retains many lessons that are still relevant today….

The royal couple also shared photographs of Sir David, including one of him with a young Prince Charles and Princess Anne in 1958, in which he is introducing them to Cocky the cockatoo, from his BBC Zoo Quest TV series. The King and Queen wished him a very happy birthday, adding: “Enjoy your special celebration this evening!” The veteran broadcaster and environmentalist has said he…
7. What causes lightning? The answer keeps getting more interesting
⭐ 63 💬 9 👤 Tomte 🔗 Discuss on HN
Physicists are using instruments originally designed to study violent cosmic events — like solar flares and supernovas — to investigate the inner workings of thunderstorms. Led by researchers like Joseph Dwyer, the field is experiencing a renaissance: lightning emits X-rays and gamma rays, and high-energy particle processes (more typically associated with black holes than clouds) appear to play a critical role in lightning initiation. After centuries of study, scientists are finally closing in on how the jagged channel of a lightning bolt gets started.
8. Making Julia as Fast as C++
⭐ 8 💬 2 👤 d_tr 🔗 Discuss on HN
Flight, Optimization, and Wind Laboratory Publications © 2026. Making Julia as Fast as C++ 18 Apr 2019, Eduardo Alvarez Introduction The rumor says that Julia can achieve the same computing performance as any other compiled language like C++ and FORTRAN. After coding in Julia for the past two years I have definitely fell in love with its pythonic syntax, multiple dispatch, and MATLAB-like handiness in linear algebra, while being able to use…
9. Wi is Fi: Understanding Wi-Fi 4/5/6/6E/7/8 (802.11 n/AC/ax/be/bn)

Clicking anywhere on a header takes you back to the index at the top of this paper. This paper details how Wi-Fi works in the United States. While most of this paper also applies to other countries, there will be subtle Wi-Fi differences supported channels, Tx power allowed, etc for other countries, for which Wikipedia has the details. ![Image 2: TX-Link Archer…
10. AI is breaking two vulnerability cultures
⭐ 343 💬 136 👤 speckx 🔗 Discuss on HN
In doing this he followed standard procedure for Linux, especially within networking: share the security impact with a closed list of Linux security engineers, while fixing the bug quietly and efficiently in the open. His goal was that with only the raw fix public, the knowledge that a serious vulnerability existed could be “embargoed”: the people in a position to address it know, but they’ve agreed not to say anything for a few days. Someone…
