What it does
MechanixCalc runs the actual governing standards — ISO 6336 gears, ISO 281 bearings, VDI 2230 bolts, DIN 743 shafts, ASME VIII vessels, EN 1993-1-8 welds and more — in your browser. What's different: every one of the 50 tools cites its standard, shows the formula and a worked example, and exports a branded PDF report a reviewer can follow. It's the bridge between a free single-answer calculator and $10k desktop software like KISSsoft/MITCalc. No install; free 30-min preview, no sign-up.
50 standards-based mechanical engineering calculators — gears, bearings, shafts, beams, fatigue, welds, pressure vessels and pipe flow — each citing the standard behind the result (or flagging it as an engineering estimate), with one-click PDF reports and a built-in AI assistant. 39+ ISO, DIN, EN and ASME standards. 14-day free trial, no credit card.
50 standards-based mechanical calculators — gears, bearings, shafts, beams, fatigue, welds, pipe flow. Every result cites the standard behind it, or says plainly when it is an engineering estimate. PDF report in one click. A calculator is easy. A calculation someone else can check — with the clause, the assumptions and a report attached — is the hard part. That is the part this does. Each result says which clause it came from — ISO 6336 for gear tooth stress, ISO 281 for bearing life, VDI 2230 for preload. Where a panel is an engineering estimate rather than a coded standard, it says so on the panel instead of implying a standard it does not run. One click turns any calculation into a…from mechanixcalc.com

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
