Seven months after Elon Musk announced that Tesla Robotaxis in Austin were operating without human safety monitors onboard, the city's service appears to have finally gone fully driverless. Over the past two weeks, all 170 Tesla Robotaxi rides in Austin monitored by the crowdsourced Robotaxi Tracker were unsupervised, the site's creator, Ethan McKanna, told The […]
Is Amp Crash a guitar amp or a guitar pedal? Yes. Death By Audio's latest is, in fact, both. While it's in a guitar pedal enclosure, Amp Crash is actually a tiny 3-watt amp hooked up to a 2-inch speaker. You can even connect an external speaker if you want. This isn't a digital re-creation […]

I love writing in Markdown. What I don't love is opening a 200MB+ Electron app just to jot down a note. So I built Markify - a desktop Markdown editor that weighs in at under 10MB and still ships a real feature set. Why bother Obsidian is great, but it's heavy, and most of what I actually need day-to-day is simpler: open a file, write, preview, export, done. Every "lightweight" alternative I tried either wasn't actually light, or was missing basics like PDF export or a proper file explorer. So I built the tool I wanted. What's in it Open & save .md , .markdown , .mdx files with native dialogs Sidebar file explorer - browse a whole folder, expand subfolders on demand, just like VS Code Three view modes : Read, Edit, and Hybrid (live side-by-side preview) PDF export with embedded images and proper Unicode font handling Light/dark theme that follows your system in real time 4 languages out of the box: English, French, German, Spanish Native title bar per platform (real traffic lights on macOS, custom controls on Windows/Linux) The stack Angular 22 (with Signals) on the frontend, Rust on the backend, glued together with Tauri 2 . That combo is exactly why the app stays small - no bundled Chromium, no Node runtime shipped, just the OS's native webview. 82 unit tests (Vitest) keep the core services honest. Everything is open source, AGPL-3.0: github.com/Martzcode/Markify Markdown is basically AI's native language now Here's the other reason this project felt worth building right now: every LLM defaults to Markdown. Ask ChatGPT, Claude, or Copilot for anything structured and you get headers, bullet lists, code fences, bold text - Markdown, every time. It's become the de facto output format for AI because it's plain text, unambiguous to parse, and renders cleanly almost everywhere. That shift changes what a Markdown editor needs to be good at: Copy-pasting AI output should just work - no reformatting, no broken tables, no mangled code blocks Code block rendering with copy b
Slack is introducing dedicated channels where teams can vibe-code together with AI agents instead of jumping between different tools and conversations. The Slack Code launch includes open, project-specific code channels with dedicated user tabs, alongside features that compare coding changes and preview HTML output before the project is shipped.

The pianist sits before her instrument. She carefully extends a front paw, pressing gingerly on a key. She presses again, and again. She is composing some soul music, because something terrible has happened to her: The vacuum cleaner has come out of the closet. Yes, my cat is a tortured artist. When Jeeves is moved […]

I run self-hosted Chatwoot as the WhatsApp inbox for a dozen or so small Israeli businesses. Two servers, a few thousand conversations a week, a drip-sequence engine bolted on the side. Chatwoot is good software. The self-hosting docs will get you to a running container. What they will not tell you is which failures actually happen at month six, when you have real customers and real volume. These five all bit me in production, and none of them looked like what they were. 1. Your disk fills from somewhere Postgres never sees I got a disk alert at 86 percent and immediately went looking at the database. That was the wrong place. DB (postgres): 680 MB chatwoot_storage_data: 17 GB Attachments live in ActiveStorage, on a Docker volume, not in Postgres. Every image, voice note, and PDF a customer sends is a file on disk, and none of it shows up when you check database size. If your monitoring watches the DB, it will report everything is fine right up until the container cannot write. The growth curve is a function of how many accounts you host, not how busy any one of them is. Mine sat at roughly 0.05 GB a month until I onboarded seven new businesses over two months, and then it hit 16 GB a month. Check the right volume: docker system df -v | grep chatwoot_storage_data 2. Forty-four percent of my outbound storage was duplicate files This is the part that surprised me. When I actually measured what was on that volume, almost half the outbound media was byte-identical copies of the same file. One 14.5 MB video was stored 48 separate times. One image was stored 325 times. Chatwoot creates a new blob and a new file on disk on every send, even when the bytes are identical. That is correct behavior for a chat app where every message owns its attachment. It becomes expensive the moment you have anything that fans one file out to many conversations. In my case it was not campaigns at all, it was the drip engine sending the same media to 48 separate conversations as ordinary outbo
Sources tell WIRED that Elon Musk is expected to spend up to $200 million in the midterms. It could be a big boost for GOP Senate candidate Ken Paxton, who’s struggled to raise cash.
This is a writeup of building a required CI gate for degraded-network behavior. The system under test is a robotics fleet substrate, but the finding applies to anyone shaping networks in CI. Ganglion exists to reach robots on networks nobody controls. Warehouse Wi-Fi, carrier CGNAT, a hospital VLAN, a customer firewall that was configured once in 2019 and has not been touched since. Until this week that claim was a sentence on a website. CI ran on clean loopback, everything was green, and the failure modes that actually matter in the field were the exact ones the test suite could never produce. That is now a required gate. Every push to main runs the full deploy, invoke and verify round trip over the relay against five shaped network profiles, and all five have to pass before anything merges. I build Ganglion, so treat the enthusiasm accordingly. The part worth your time is not that it went green. It is what I got wrong on the way there. The five profiles clean : baseline, no shaping. If this one fails, something else is broken. lossy : packet loss with light reordering. high-latency : 250ms round trip. asymmetric : plentiful downlink, starved uplink. This is the one nobody tests and the one teleop actually dies on, because control acknowledgements go the starved direction. nat-relay : endpoints with no route to each other at all, forcing hole punching to fail and relay fallback to carry the session. The last two are the ones I care about. Loss and latency are what people imagine a bad network is. Asymmetry and no-direct-route are what a bad network usually is. What I got wrong The original design assumed you can pin netem's seed and get a repeatable lossy run. Two profiles: a pinned-seed one that gates the build, and a nastier randomized one that runs nightly and is allowed to fail. You cannot pin netem's seed. Its loss and jitter draw from the kernel RNG and there is no seed parameter to set. A "deterministic lossy netem profile" is not a thing that exists. This m
During a recent visit to Generalist AI, I watched a robotic arm improvise and use a banana as a tool.

What if deciding what to eat felt as exciting as winning a championship? It's 2 AM. You're hungry. You open your favorite food delivery app, convinced you'll order something in two minutes. Thirty minutes later, you're still scrolling. Pizza? Burger? Pasta? Fries? Momos? Ice cream? Suddenly, every option looks equally good, and now you're questioning your entire existence just because you wanted dinner. I have this problem almost every time I order food. So when I saw the DEV Challenge, I wanted to build something fun around this tiny but painfully relatable problem. Unfortunately, I couldn't finish it before the deadline, but I still wanted to share the idea because it's one of those projects that made me smile while building it. Meet Foodwars . Instead of endlessly scrolling through hundreds of dishes, why not let your favorite comfort foods battle each other until only one champion remains? What I Built We've all watched cooking shows like MasterChef and somehow turned into professional judges sitting comfortably on our sofas. "That steak is overcooked." "The sauce needed more balance." "I would've plated it differently." As if Gordon Ramsay personally asked for our opinion. Foodwars lets us finally put those imaginary judging skills to good use. Instead of comparing hundreds of dishes at once, the platform randomly pairs comfort foods against each other in head-to-head battles. You become the judge. Pick the winner, move on to the next matchup, and continue until one food survives the tournament. No endless scrolling. No decision fatigue. Just a series of fun, quick decisions that eventually crown your Ultimate Comfort Food . And once the champion is decided... Go order it. Or cook it. Either way, dinner has finally been decided. Demo comfort-foodwars.vercel.app Features of Foodwars Foodwars isn't just a random food picker. Every round is designed to make choosing food feel like a game instead of a chore. 1.
