Just experienced one of those bugs that makes you question why we wrote Dragonfly in C++ instead of Rust or Zig... 🦀⚡ github.com/dragonflydb/dr…
The Redpoint InfraRed 100 is now live. These are the companies building the infrastructure that powers everything happening in AI right now, from world models and agent runtimes to the sandboxes, databases, and security tools agents depend on. Congratulations to this year's honorees! Read the full 2026 InfraRed Report: our state of the union on AI and cloud infrastructure 👉 redpoint.com/reports/the-in…
@Google , you got confused! 🤦♂️ Apparently, my "מתכונים" (Recipes) document violates Google Drive’s Phishing policy. I mean, I know my stuffed peppers recipe is a great way to lure people to my kitchen, but I didn't think the Trust & Safety team would consider it actual cybercrime. Watch out, those carbs are malicious. 🛑 🍕
@glcst I am seriously considering moving all our non-necessary workloads from GCP to another cloud. This incident is not about a bug. It's about a faulty process. This company is in full AI mode and frankly I do not want to be the another victim of their next vibe-coded script.
@axboe Are you in an AI-free coding camp? :)
@dragonflydb v1.38.1 patch release 📷 3 fixes: → Fixed O(n) scan in WATCH notification queue — this could stall commands when many keys were watched simultaneously → Fixed journal executor reuse during replication — improves replication efficiency → Fixed socket leak with BLPOP blocking connections Might help with stability around job-management use-cases.
Dragonfly v1.38 is out 🚀 The big one: **up to 26% memory reduction** for TTL workloads! We eliminated the separate expire table entirely and embedded expiry directly into each key. 10M keys: 900 MB → 665 MB. No config changes needed.
I couldn't have solved this alone because the forensic work required ARM64 memory layout depth I don't have. The AI couldn't have solved it alone because it lacked the system-level intuition to pivot away from its own hallucinations.
The Root Cause: A rare execution path where the S3 library combined with DNS resolution consumed more stack space than allocated. On ARM64, this overflow was silent until the corrupted memory was accessed by the next coroutine.
Everyone talks about AI writing code. Nobody talks about the harder part: debugging. Last week, I spent 12 hours hunting a segfault in Dragonfly during S3 backups. Here’s how I used AI as a forensic partner to solve a "ghost in the machine" memory corruption bug on ARM64. 🧵
Europe is in hibernation mode and it's both scary and embarrassing. And unfortunately, it's not clear if it will be able to evolve to save itself in time.
Dear Mr. Armin Papperger, CEO of Rheinmetall, When you referred to Ukrainian drone manufacturers as “Ukrainian housewives with 3D printers” you revealed just how deeply the European defense establishment still fails to understand the nature of modern warfare. This is not about
@dragonflydb @CeleryOrg @laravelphp The feature is experimental, shipping in the next Dragonfly release. Benchmark repo: github.com/romange/python… PR: github.com/dragonflydb/dr…
@dragonflydb @CeleryOrg @laravelphp Not everything compresses equally. RQ, Dramatiq, Taskiq — minimal gains. Different data structures, less redundancy. This is pattern-dependent. But for JSON-heavy list workloads, the savings are dramatic.
Two weeks ago I shared how much memory popular job queues consume in Redis. I said we were working on something at @dragonflydb. Here's what we built. 🧵
I got curious: how much memory do popular job queues actually use in Redis? I benchmarked @celeryorg, @laravelphp, Sidekiq, RQ, Dramatiq, and others — 200K jobs across 10 queues each. The differences are massive. 📷
