Memo to self: do not put a glass which has been used for measuring dish washing liquid into a dishwasher without rinsing. No photo, because I was frantically getting towels to stem the frothy overflow!

Critical #NGINX #Vulnerability Can #Crash Workers and May Allow Remote Code Execution

The #overflow lives in nginx's #script engine, the code that assembles strings from directives at request time. It only surfaces under a specific #configuration: a regex-based map whose output variable is referenced in a #string expression after a capture from an earlier #regex match.

Sorry, #Fedi - Mastodon was telling me "999 new posts", so I just skimmed everything. If I missed something cool, one of the cool people I follow will probably boost it.

(Does Mastodon's default web client cap the number displayed to 999? Or did I just hit it by coincidence?)

THANK YOU ALL!!! - what errors should I check for and handle?

Thank you all for your kind, patient and educative responses when I obnoxiously post amateur questions! 💙 While I cannot make any promises because of how my brain works, I am almost ready to continue reading *The C Programming Language, 2nd Edition”. I just want to experiment a little bit with error handling, specifially how to handle wrong input (char VS. int, etc.) and also to learn to indentify code that runs the risk of overflow/underflow.

Question: what errors do you recommend checking for and handling?

Meanwhile, thank you all! 🥰

//Function declarations  
int newPin();  
int checkPin(int i);  

//Program that prompts for, verifies and saves pins temporarily into an array

In Java unterscheidest du grob zwischen primitiven Datentypen und Referenztypen. Primitive Typen sind die Basis: Sie speichern den Wert direkt, ohne Objekt-Hülle. Das macht sie schnell, vorhersehbar und speichereffizient. Wichtig ist dabei: Die Größe der primitiven Typen ist in Java fest definier

Security Patches

InfoSec

Regardless of which Operating System you run, it is important to keep up with the critical updates to keep your machines as safe as possible

• Realize that by the time a critical bug has been reported, verified, patched and delivered to your distribution of choice, a significant amount of time has passed...
• From the first day the bug has been discovered [zero day] to the day you patch your computing machine, you've had a vunurable open machine in that one respect.
• Keep the amount of time between the availability, of patches & the update of your machines, especially your VMs (Qemu et al) & physical servers as short as possible
• Make sure to always use manual updates on your server VM's!
• I shall not explain why, start reading on Wikipedia and furthe, the explanation is too long for this short post

Notes:

• every OS can have vunurabilities
• Security in obscurity does not work!
• you are not secure because you run obsolete AmigaOS QNX or cool and niche *BSD as an OS
• buffer overflows hide everywhere
• I reguraly find them!

Wow. An important monitoring tool for #Nvidia #GPUs, nvidia-smi hangs indefinitely after ~66 days of uptime. Corresponding to when a count of "jiffs" (750 Hz) would overflow a 32-bit unsigned number.

Hi, Mastodon 🦣 can you help me out?

If you can test in actual Safari, what do you see for this demo?

https://codepen.io/thebabydino/pen/EayKKjQ??editors=1100

Is it the result in the first screenshot? (what I get in Chrome & Firefox)

Or the result in the second screenshot? (what I get in Epiphany)

If you cannot test yourself, boosts appreciated. 🙏

Thank you!

CASTing huge number to INT causes overflow! SQL doesn't error, it wraps around or returns NULL. This breaks number conversion! Watch!
