Today I've developed a Proof of Concept #PoC for a Denial of Service #DoS #vulnerability discovered during an investigation into a service issue earlier today. The PoC can reliably trigger either a process crash or an infinite loop leading to resource exhaustion.

Many EU member states are arguing for forcing WhatsApp to inspect all our photos w/AI. If the AI is in any “doubt” if it might be child pornography, your photo, location & other details get reported to Europol and a local police force.

Why is the GRUB 2 menu so slow on a UHD display with an Nvidia graphics card? This, combined with the input lag, creates a maddening effect. After every key press, you have to wait for several seconds, maybe hit backspace, and then wait again... #GRUB #Nvidia #UHD #bootmenu #linux #joy #lag

Is "sovereign washing" the new "privacy washing"?

Microsoft, Google, AWS published “sovereign clouds”.

❌ BUT digital sovereignty doesn’t come from shiny new product names.

✅ Digital sovereignty comes from full European legal and technical control.

A GitHub binary download rate throttled? Has anyone noticed if GitHub implements some kind of download speed limit? And do downloads frequently seem to be restricted to around 100 KiB/s ~1Mbit/s. The speed then constantly fluctuates around that level. #github #download #speed #throttling
