Resend's API for sending a templated email is three steps: Create a template Publish the template Send an email using that template Each step depends on the one before it. The template ID from step 1 has to be passed into step 2. The published status from step 2 has to be confirmed before step 3 will actually send. And i...

We Open-Sourced 627,000 Labeled Edge-IDS Verdicts on HuggingFace

Every week someone asks us on Discord the same question: where can I get a labelled intrusion-detection dataset that actually looks like the internet, not a lab? Today the answer stops being "you can't." We just published hookprobe/edge-ids-threats — 627,853 verdicts produced by our production edge IDS, labelled by the SENTINEL ensemble, enriched with country and ASN, and free for academic or comm...

Programming Hopper GPUs: The Memory Consistency Model

You've decided to write fast code for an NVIDIA Hopper GPU. Maybe you want to build a custom attention kernel. Maybe you're trying to understand how CUTLASS and ThunderKittens work under the hood. Either way, before you can use any of the cool Hopper hardware — TMA, wgmma, mbarriers, clusters — you need to understand one thing: how memory works when thousands of threads share it. That's what the ...

Most PDF Redaction Is Broken. Here's What "Real" Redaction Actually Requires.

All tests run on an 8-year-old MacBook Air. Drawing a black rectangle over text is not redaction. The text is still there. Select all, copy, paste into Notepad — it appears. This has leaked classified documents from actual government agencies. Multiple times. Real redaction destroys the underlying data. Here's how I implemented it. What fake redaction looks like PDF structure ...

A Background Job Was Crashing Our JVM Every Week - Until We Taught It to Stop

Some Java services don't fail because of traffic. They fail because background jobs don't know when to stop. A background job should never be able to take down your production system. Ours did. Every week. At SAP, we ran a multi-tenant service processing thousands of tenants. Every morning, a scheduled job kicked off - telemetry, cleanup, routine work. Nothing unusual. Until it overlapped wi...

Local coding with AI: It works… Just not on my laptop

Digression It's been a while since the AI have hit the public in a way that some user use it to plan vacation and do basic addition with it. That pretty much at the same time that we (developer) discover a new tool can help (to ruin the market) to allow us to work a little bit faster. I have a little of a hate/love relationship with this tool mainly because I wonder were (has humanity)...

Raspberry Pi IP Scanner App – Find Your Pi on the Network Instantly

Anyone running a Raspberry Pi in their home network knows the problem: What is the Pi's IP address right now? DHCP assigns a new one after every restart, and digging through the router interface gets old fast. That's exactly why we built the raspberry.tips App for Android — an IP scanner built specifically for Raspberry Pi, combined with all the tools from the website, right on your phone. ...

Everything You Need to Know About Automatic Cipher Suite Ordering

The Go standard library provides crypto/tls, a robust implementation of Transport Layer Security (TLS), the most important security protocol on the Internet, and the fundamental component of HTTPS. In Go 1.17 we made its configuration easier, more secure, and more efficient by automating the priority order of cipher suites.

Is AI Really the New Compiler?

Unlike traditional compilers, AI is not completely trustworthy, and describing what you want in natural language can never guarantee the outcome is exactly what you desire. Therefore, it would be a serious mistake to think you can treat your AI-generated code the same way you treat a compiler's output.Read All

Identity Is the New Perimeter: Managing AI Agents As Digital Actors

As cloud systems, remote work, and AI agents dissolve traditional security perimeters, identity is becoming the new control layer. The article traces the evolution from perimeter-based security to zero trust and now to identity-first architectures, where every actor—human or AI—is continuously verified and governed. With AI agents acting autonomously across systems, organizations must treat them a...

OCR in the Browser: How Tesseract.js Makes PDF Text Extraction Free

You've got a 200-page PDF that someone scanned years ago. It's just images of pages — Cmd-F finds nothing. You need to extract the text, search through it, maybe paste a paragraph into a doc. Five years ago, this meant a cloud OCR API at $1.50 per 1,000 pages, plus uploading your potentially-sensitive PDF to a third-party service. Now it means dropping the file into a tab and waiting two minutes....

Dopamine Isn’t Connection: Why Online Interaction Feels Empty

A Los Angeles jury found Meta and YouTube liable for addicting a teenager. The verdict matters — but the real problem is biological. Dopamine without oxytocin is stimulation without bonding. Until tech companies build business models around real-world connection, the incentive structure won't change. The brain is still waiting.

[AskJS] Why did everyone stop using Meteor.js?

If you used Meteor at some point — for a side project, a startup, at work — and moved on, I’d love to hear the actual breaking point. Not the meme version. The real one. A few things I’m specifically curious about: - Was it a technical limit you hit (scaling pubs/sub, MongoDB lock-in, bundle size, build times)? - Was it ecosystem fatigue — Atmosphere vs npm, fewer packages, slow releases? - Was it...

A reader comment made me realise I'd only solved half the problem

A reader comment made me realise I'd only solved half the problem Last month I wrote about the cron job failure mode nobody talks about: the job that doesn't die, it just drags. The short version: a nightly ETL job at a previous employer took four hours instead of forty minutes for six days before anyone noticed. It ran. It completed. It exited zero. Every dashboard showed green. Downs...
