GitHub Trending: Today — n8n, yt-dlp, Plane, Superset, TinaCMS (github.com)

Today's trending list is a catalogue of escape routes from SaaS bills: n8n (visual workflow automation against Zapier), Plane (project tracking against Jira), Apache Superset (BI dashboards against Tableau), and TinaCMS (Git-backed visual CMS).

But "open source" is doing uneven work here. n8n runs on a fair-code license the OSI won't recognize, Plane gates SSO behind a paid contract, and the one genuinely community-run tool, yt-dlp, just told users they must install a separate JavaScript runtime to keep downloading from YouTube.

Not just a headline — the discussion unpacked

The top HN threads: facts from the discussions, both sides, insider voices. Email, Telegram, or RSS.

Resident Evil Requiem тасует вид от первого и третьего лица, и это работает (store.steampowered.com)

Девятая номерная часть survival-horror от CAPCOM: вы исследуете полузаброшенные локации, считаете каждый патрон и решаете головоломки, а монстры выходят буквально из темноты.

Но не для всех это шаг вперёд. Часть ветеранов соглашается: эффектная смена ракурса хороша, а вот остальное местами откатилось назад относительно прошлых частей.

Самая безумная лига Path of Exile вернулась: классы теперь можно сплавлять воедино (store.steampowered.com)

Path of Exile — глубокая action-RPG от Grinding Gear Games: вы фармите подземелья, выбиваете лут и конструируете билды такой сложности, что новички уходят в гайды на часы.

Но в потоке свежих отзывов громче всех звучат не фанаты лиги, а те, кого внезапно забанили, иногда за чужие нарушения в случайной гильдии.

Sons of the Forest снова на волне: кооп про остров каннибалов опять зовёт компании (store.steampowered.com)

Sons of the Forest — выживание от Endnight Games: вы упали на острове, населённом мутантами и каннибалами, строите базу, крафтите оружие и пытаетесь дожить до утра в одиночку или с друзьями.

Один нюанс: игра почти ничего не объясняет. Многие механики приходится искать в гайдах на YouTube и Reddit, рискуя поймать спойлер.

Subnautica вернулась в топы Steam, пока сиквел заставляет вспомнить оригинал (store.steampowered.com)

Subnautica — одиночная выживалка от Unknown Worlds: ваш корабль рухнул на океанической планете, и вы строите базы, добываете ресурсы и постепенно раскрываете, что случилось с экипажем.

Сейчас вокруг игры снова шум: на фоне сиквела игроки вернулись к оригиналу и поглядывают на вторую часть, которой, судя по отзывам, нужен мощный ПК.

Бесплатные выходные у Sniper Elite: Resistance, а игроки прозвали её «частью 5.5» (store.steampowered.com)

Серия Sniper Elite — это тактический шутер про снайпера во Второй мировой с фирменной «рентгеновской» камерой, которая в замедлении показывает, как пуля дробит кости врага.

Resistance добавляет нового героя и режим пропаганды, но карты стали меньше, а озвучка вызывает смех. Спасает одно: взрывными патронами можно подрывать живых игроков, вторгшихся в вашу кампанию.

Bun is adding real shared-memory threads to JavaScript, and the PR description was written by Claude (github.com)

`new Thread(fn)` runs a closure on another OS thread inside the same heap, no postMessage, no structured clone, no SharedArrayBuffer. It implements a 2017 design that, until now, nobody had shipped.

Buried in the writeup: the garbage collector still stops the world. A VM-internals reader flagged it as the line that will wreck tail latency. Bun's creator, meanwhile, confirmed the whole PR description is Claude-generated.

The UK age-gated social media, kids switched to VPNs, so now the government is eyeing VPNs (birminghammail.co.uk)

Having age-gated social media through the Online Safety Act, ministers are now studying VPNs as the next enforcement gap. The article carrying the story turned out to be a clickbait aggregation a reader debunked on the spot.

A security researcher's counter cut deeper than the tech: the Great Firewall of China is technically beatable and has still achieved exactly what it set out to do.

Cloudflare built throwaway accounts so AI agents can deploy, and humans quietly got free 60-minute previews (blog.cloudflare.com)

`wrangler deploy --temporary` provisions a working account with no registration, live for 60 minutes, claimable into a permanent one via a link. The failure message tells the agent the flag exists, so it self-discovers the path.

One developer called handing deploy control to a non-deterministic process 'madness'. The simpler objection: humans get pushed into endless Turnstile loops while bots get a frictionless lane.

A marketing agency reprinted an entire bestselling book, swapped the art for DALL-E, and outranked the original (waxy.org)

The bootleg sits on thedictionaryofobscuresorrows.com versus the real dictionaryofobscuresorrows.com — full foreword, every neologism, every etymology, with a GPT 'Submit A Sorrow' generator bolted on. Two DMCA takedowns did nothing.

The twist a reader traced: the affiliate link points at the genuine book, tagged promptdigital-20. The theft monetizes through Amazon's own loosely gated program.

A satellite found 'immense' GPS jamming, sold by the company whose new product happens to fix it (space.com)

From 500 km up, Xona says jamming was so widespread that 'as soon as we started doing any operations above Europe, we noticed something going on'. It pitches a stronger LEO signal that would shrink a jammer's reach to about 5% of today's.

A networking engineer's rebuttal was physics: whatever transmitter you bolt to a satellite, a ground jammer has no power or size budget and can simply out-shout it.

South Korea is winning arms deals on a number Politico barely mentions: its howitzers cost half as much (politico.com)

Korean systems run 40-60% cheaper unit for unit: K9 at ~$3.5-4M vs Paladin ~$8M, Chunmoo MLRS ~$2M vs HIMARS ~$4.5M, 155mm shells ~$2k vs ~$3.5k. Seoul fields 2,780 self-propelled guns, third in the world.

The self-reliance traces to Vietnam, where Korean troops carried WW2 rifles and a frustrated President Park spun up a domestic defense agency.

A Tesla on a driver-assist system killed a woman in her own house, and the thread fought over the title (abcnews.com)

No charges yet; the driver was uninjured-ish, cooperative, not intoxicated, and reportedly failed to keep a single lane. Tesla's own site says the feature 'requires active driver supervision and does not make the vehicle autonomous'.

The line that stuck: naming a product 'Full Self-Driving (Supervised)' is like selling 'Healthy Dog Food (Rat poison)'.

Europe wants to build its own social media, and the thread coined a word for the plan: openwashing (european.social)

european.social pledges eight principles across Matrix, the Fediverse and the AT Protocol, plus a 'Eurobridge' and identity tied to the EU Digital ID Wallet. 445 individuals and 67 orgs signed.

An engineer's warning: don't plan a Neuschwanstein castle by committee — build a wooden cabin and expand. Gaia-X is the cautionary tale.

A writer admits he now trusts books published before 2022 more, and the thread split on whether that's wisdom or rose-tint (notes.lorenzogravina.com)

The essayist concedes he discounts post-2022 work 'especially from authors I haven't heard of', while admitting LLMs 'can create great results' and that he has no solution.

The counter that cut deepest: pre-2022 wasn't carved in stone. LinkedIn slop was human-generated before it was AI-generated. The problem was never the author, it was the slop.

History says export controls never stopped crypto. The thread says this time the target is different (techcrunch.com)

Zimmermann beat the 1990s arms-export case by publishing PGP source as a printed book. The article asks if the same futility applies to a model Anthropic was ordered to restrict within 90 minutes.

The correction: PGP ran on any PC. A hosted model's dependence on centralized compute is exactly what makes export control bite.

A Lithuanian startup turns old Android phones into a crowdsourced Shahed-drone listening network (lrt.lt)

Drone Rada wants 10,000 phones across the Baltics and Poland, using devices already sitting in drawers and no technical skill from volunteers.

The hard objection: Shaheds have climbed from ~500m to 2,000-3,000m, with the newest reaching 5,000m — high enough to be near-inaudible from the ground.

Windows 11's media player idles at 377MB doing nothing, and the experts say the real story is older and worse (extremetech.com)

By the article's own figures the modern player idles at ~377MB against ~103MB for the old one. The codecs it locks behind a fee, like HEVC, have been paid add-ons since the Windows 10 era.

The detail that stung an ex-Microsoft engineer: it's a native app with no web version that Microsoft still chose to build in HTML and JS.

Mammals didn't lose the ability to regrow limbs, they switched it off, and two growth factors can switch it back (sciencedaily.com)

The finding: the regenerative cells are already there, you just have to make them behave. After wound healing, FGF2 redirects cells toward a blastema-like structure, then BMP2 tells them to build new tissue.

A reader with permanent retinal damage noted the same trick in retinas often triggers tumors, the recurring asterisk of the whole field.

Wired exposed a secret network of tech elites planning the future, and the most damning detail is that it runs on Airtable (esquire.com)

The leaked 'Dialog' network, linked to Peter Thiel, kept returning to one theme: AI will reorder work, war, education and belief within a few years.

The puncture line: a secret cabal running the world, on AirTable. Wired never used the word 'cabal' that Esquire's headline did.

A free 'AI-powered' Crunchbase alternative listed Anthropic at an $18B valuation. The real number was off by 50x (startupwiki.tech)

The maker pitches AI agents plus community contributions and an 'agent ledger'. Commenters found stale figures, missing companies and badges that link to nothing.

The most useful fix offered: federate with Wikidata, which would pull in connections back to Crunchbase and other sources for free.

Ask HN: will the RAM shortage finally make programmers write lean code? The thread's answer is a tired 'no' (news.ycombinator.com)

The recurring diagnosis: the bloat is architectural, not algorithmic. Bundling Chromium to ship a chat app is the problem, not your choice of data structure.

Where optimization will actually happen, per a big-tech engineer in the thread: server-side, where RAM is a line item, and mostly by 'stop doing stupid stuff', not fancy algorithms.

Linux finally deleted strncpy after six years and 360 patches, and a programmer who saw it born called it 50 years late (phoronix.com)

strncpy was killed for 'counter-intuitive semantics' around NUL termination and wasteful zero-filling. The '360 patches' figure is 360 uses converted to safer calls, not 360 bugs.

The origin: it was written to copy 14-byte, zero-padded-but-not-terminated filenames out of early UNIX directory entries. It was never meant for strings.

He stored a whole web page inside a favicon. The thread had three older, cleaner ways to do it (timwehrle.de)

The method: encode bytes into RGB channels with a 4-byte length header. A 208-byte page fit in 71 pixels, inside a 9x9 image, using 87% of capacity.

The reveal that one-ups it: PNG already has tEXt comment chunks built for stuffing arbitrary text into a normal-looking image.

Someone turned the Apple Vision Pro into an X11 server, and the thread bet X11 will outlive visionOS (lispm.net)

It accepts X11 connections over TCP, renders framebuffers at native resolution, does MIT-MAGIC-COOKIE auth, and even ships experimental GLX so OpenGL clients work 'as reliably as they did in the 2000s'.

The line the room loved: does anyone else suspect X11 will outlive visionOS?

A 1989 flight sim is being rebuilt from its DOS binaries, and they need pilots who still own the original to find the bugs (neuviemeporte.github.io)

The pipeline: full reverse to assembler, then assembler to byte-identical compiled C, all still on DOS, then the Linux and Windows port begins.

The catch that makes testing hard: it's a bug-for-bug reconstruction, so original quirks like disappearing objects must be preserved, not fixed.

Finnish libraries lend sewing machines, and the thread did the math on why it works there and stalls in Denver (bbc.com)

55% of Finns visit a library at least monthly; the UK manages 30% on yearly figures. One commenter called a sewing machine 'a space ship' next to a book in terms of skill and fragility.

The blunt consensus line: this only works in a high-trust society.

The most artificial color on Earth is a green laser, because nature almost never makes pure 520nm light (moultano.wordpress.com)

Three cone types and three display primaries mean every screen is trapped inside a triangle on the CIE chart; pure cyan would need physically impossible 'negative red'. Around 500 bird species exceed sRGB.

The kicker: nothing in nature reliably makes saturated ~520nm light, so a green laser is 'the most artificial color in the world'.
