betteralign v0.12.0 is out at github.com/dkorunic/bette…! A major upgrade for Go developers: improved robustness, faster performance, a completely rewritten & fuzz-tested AST decorator, refreshed docs, and updated benchmarks. Especially effective in large monorepos. #golang #devops
I know it is really hard to understand how much better and improved the proxmark3 has become over the years. Here is a graphic list of the following card technologies that is currently supported in #proxmark.
🔺NEW: Formally verified post-quantum ML-KEM and ML-DSA in corecrypto, with correctness proven from the FIPS spec down to hand-optimized ARM64 assembly — a world first at multi-billion device scale. And we're releasing our Isabelle libraries, ARM64 model, and Cryptol-to-Isabelle translator to advance the state of the art in verified cryptography! security.apple.com/blog/formal-ve…
betteralign github.com/dkorunic/bette…: evolved fork of Go's fieldalignment. Preserves field comments through reordering, skips generated files, atomic writes. Months of allocation profiling baked in. Serious struct padding without wrecking your codebase. #golang #devops
Spent the weekend nights reviving a 15-year-old toy project of mine: a Linux uptime spoofer. Ported it to modern kernels and refreshed the codebase along the way: github.com/dkorunic/uptim… #linux #kernel #devops #security
Tomorrow I’ll be giving a talk at Bsides Varaždin titled "Caveats of Using eBPF in Linux". If you're interested, you can check out the slides here: dkorunic.net/pdf/Korunic_eB… Feel free to stop by, listen in, and join the discussion! #ebpf #linux #sysops #kernel
Astrophotography has a quiet magic I didn’t expect. Valentina and I have been spending our nights under the stars, and this is what came out of it: ~700 frames, 20s each, capturing Bode’s Galaxy. Curious to hear what you think ✨
The latest Proxmark3 release is called BREAKMEIFYOUCAN! Not a random name. That is the actual 3DES factory default key NXP burned into every MIFARE Ultralight C they shipped since 2008. Somebody finally broke it properly. The paper drops the keyspace from 2^112 down to 2^28. Counterfeit cards fall in under 60 seconds from a single card interaction. The tooling is merged: github.com/RfidResearchGr… #Proxmark3 #RFID #NFC #MifareUltralightC #NXP #OpenSource
🦀 Rust: Deadlock-Free Mutexes Instead of hoping lock ordering is correct at runtime, Surelock pushes deadlock prevention into the type system: • invalid lock ordering rejected at compile time • ergonomics that still feel practical notes.brooklynzelenka.com/Blog/Surelock #rust #rustlang
Han Lee: The AI Great Leap Forward leehanchung.github.io/blogs/2026/04/… #ai #programming #devops
Senko @senkorasic has got some clever tricks for AI-driven mutation testing definitely worth trying! 🔍🤖 blog.senko.net/improving-ai-g… #programming #ai #claude #devops
@senkorasic Great idea and it works really well. LLMs are excellent at identifying which parts of code to mutate!
Diving Into Coverage-Guided Fuzzing from @pierrezemb.fr pierrezemb.fr/posts/diving-i… #programming #devops #fuzzing
I’ve updated my iSMC tool github.com/dkorunic/iSMC: It now supports decoding and displaying temperature, fan, battery, power, voltage, and current data on M5 hardware - and should work well with older hardware too. #macos #cli #sysops #monitoring
A tale about fixing eBPF spinlock issues in the Linux kernel rovarma.com/articles/a-tal… #ebpf #kernel #devops #programming
1 million context window: Now generally available for Claude Opus 4.6 and Claude Sonnet 4.6.
In my spare time I’ve been improving the eBPF code in github.com/dkorunic/pktst… . What helped most was a colleague running ancient Linux kernels - it pushed me to go the extra mile working around CO:RE limitations and filling gaps in my own knowledge.
🌟 Go 1.26.1 and 1.25.8 are released! 🔐 Security: Includes security fixes for the standard library (CVE-2026-25679, CVE-2026-27137, CVE-2026-27138, CVE-2026-27139, CVE-2026-27142). 🗣 Announcement: groups.google.com/g/golang-annou… ⬇️ Download: go.dev/dl/#go1.26.1 #golang
