I just earned the Active Directory Red Team Specialist certificate from @cyberwarfarelab! I started taking it when I was attending a conference and got impressed by the knowledge I could acquire. Recommended. Next cert: CRT-ID?

the cost of a virtual call was never the vtable lookup. that's just a pointer load, and modern CPUs are very good at loads. what actually matters is the indirect branch that comes after it. the CPU wants to know where execution goes next so it can keep speculating ahead. When the branch predictor gets that target right, a virtual call is often surprisingly cheap. the trouble starts when the same call site sees many different targets. prediction becomes harder, mispredictions increase, and the CPU has to throw away speculative work and start again. that's why a monomorphic virtual call site can be almost free while a megamorphic one can become expensive. virtual calls are slow was always an incomplete explanation. the real question is how predictable the call target is.

hot take: raspberry pis are overrated. you can buy a cheap thinkcentre tiny for well under $100, even though AI has messed up their prices too.
A Raspberry Pi with 16gb of ram costs like a laptop with 8gb of ram. Is the ram the real difference or something else?

You might not believe it, but in the older version of clang, the code on the left produces Hello World!

i was reading the SQLite source and found that DELETE does not actually shrink the database file deleted pages are placed onto an internal freelist inside the file new inserts reuse those free pages before growing the database again the file itself only gets smaller when you run VACUUM delete everything from a 1GB database and the file is still 1GB until you compact it

> Microsoft GitHub repos banned > "Terms of Service violation" > ??? > Look inside > Was compromised ... was Microsoft going to become a victim of a supply chain attack on their own platform via their own product?
🚒More fallout from the Mini Shai-Hulud campaign 49 Microsoft, Azure, and Azure-Samples GitHub repos were removed at 16:00 UTC for Terms of Service violations This is linked to news this morning that attackers had regained access, after the previous durabletask compromise
