The annoying thing about Econ twitter is that when you see a Prof spouting garbage, you can't clap back because that paper will def never get published if you do

Big day for dudes who write all of their passwords down on a slip of paper that they keep at their desk
I cannot stress enough how AI has made teaching so much better. A joy even.
Admin? Automated.
Pulling updated data sets day of class for hot and fresh discussion? Done.
Processing of new papers and materials. Easy peasy
Incredible stuff.
JFC.
🚨 BREAKING: LINUX IS NOW FACING TWO CRITICAL SECURITY VULNERABILITIES, AND THERE ARE NO OFFICIAL KERNEL FIXES YET.
Both rated 9.0/10 in severity.
One could allow hackers to take control of vulnerable servers WITHOUT EVEN LOGGING IN.
And the most alarming part? The flaws were made PUBLIC before patches were ready.
Here's what's happening:
→ TWO CRITICAL RCE FLAWS: Both affect KSMBD, Linux's built-in SMB file server.
→ NO PASSWORD REQUIRED: One vulnerability could allow unauthenticated attackers to execute malicious code on vulnerable servers.
→ KERNEL-LEVEL ACCESS: Successful exploitation could potentially give attackers control within the Linux kernel itself.
→ NO MAINLINE PATCH YET: Both vulnerabilities were publicly disclosed before official kernel fixes were available.
→ DISCOVERED BY AI: Trend Micro's AI-powered security scanner identified the flaws.
→ SERVERS AT RISK: Linux systems running the vulnerable KSMBD service need immediate attention, especially if port 445 is exposed.
First PHP. Then Node.js. Then GitLab. Then Python.
NOW LINUX.
And this time, the vulnerabilities are PUBLIC before the fixes are ready.
If you manage Linux servers, CHECK YOUR EXPOSURE NOW.
Readers added context they thought people might want to know
KSMBD is a rarely used optional in-kernel SMB server distinct from the common Samba implementation; it is not enabled or shipped by default on major distributions like RHEL, and the flaws affect only systems explicitly running it with port 445 exposed.

Philomena: Some people have been writing PHP for over 20 years. Is that because it's particularly difficult to finish?
Expert: No, software is constantly evolving.
Philomena: So they've been writing the same website for 20 years?
Expert: No, different projects.
Philomena: Have they tried finishing one before starting another?
Expert: That's not how software development works.
Philomena: My mate Paul spent 20 years building a shed. Turned out he was just an alcoholic.
Expert: Right.
Philomena: Is PHP like that?
