I wonder how many ultra wealthy people there are out there whose wealth and power is FAR higher than their Forbes numbers, they just keep it quiet and do their evil shit through proxies and shell corps. Like what if even Elon had to dance to people's tunes because they could destroy Tesla with a phone call.

I think it's a friendly-feeling smile. I know like I'm not necessarily your friend or anything, but like, it feels friendly. Like I'd feel comfortable and invited to have conversation with you, but I guess that's self evidentin most other animals bared teeth are a threat display.

Here is a fun piece of Linux filesystem trivia that feels like dark magic the first time you see it: rm does not delete files.In POSIX, rm invokes the unlink() syscall. All it does is sever the directory entry (dentry) and decrement the inode's hard link counter by 1. The kernel will only actually deallocate the extents and free the disk blocks when two conditions are met, a.) the hard link count drops to 0 and b.) the open file descriptor (FD) reference count drops to 0.This is why you can rm a 200GB log file and watch df -h stubbornly stay at 100%. The daemon holding that file descriptor is still happily writing to unlinked disk blocks.That said if someone accidentally runs rm on an active, in-use database flatfile or massive dataset, maybe don't panic and don't kill the process. As long as that process is alive, the inode is fully intact. Find the PID and look into the virtual filesystem, ls -l /proc/<PID>/fd/You will likely spot the descriptor pointing to /path/to/file (deleted).You can then resurrect the entire file right out of the kernel's file table by dumping the descriptor back out, try cp /proc/<PID>/fd/4 /recovered_fileAnd if your disk is full because of an unlinked runaway log and you can't restart the daemon, don't restart it. Truncate the inode directly through its descriptor, /proc/<PID>/fd/4Zero downtime while the VFS does its job. Understanding inodes is a superpower that anyone can acquire.#linux #sysadmin #filesystem #kernel #storage #unix #devops #bash #programming

A fire at a Starlink ground station in central Poland on Wednesday night is being treated as deliberate sabotage. The station is state-owned and carries internet traffic onwards to Ukraine, including for its army. It stayed operational.Denmark's intelligence service warned the same week of destructive cyberattacks and sabotage against Nato states in the coming months. Germany has blamed Russia for an attempted drone attack on Leipzig/Halle airport. France has ordered a protection plan for critical infrastructure sites.The practitioner point is not geopolitical. Connectivity to a war zone ran through one commercial satellite provider and one physical building. The same question applies at every scale: where does your traffic go, and what burns down.https://www.bbc.com/news/articles/cmp30r1klk37o#CyberSecurity #CriticalInfrastructure #InfoSec #HybridThreats
