Compile with Fil-C and run it a few times. Most of the time, it will trap. However, every few times, it will print "secret password".
This covers the scenario where a malicious user causes a program to leak information using an overflowing offset. Typically Fil-C will mitigate this kinds of thing with a bounds check. However, a data race can cause the bounds on a pointer to be incorrect.

Hybrid (or on-call) working arrangements often cause us to carry an employer-issued laptop between home and work (and wherever else on the way). While they are not very heavy (particularly the 14.1" screen models), they still require a backpack. And in winter, a car, so that the internals don't cool down on a transit stop/while pedalling and don't condensate the vapour from the air after being brought inside a building.
Can it be simpler if one's workflow allows them to turn off the system (instead of putting it to sleep)? Cloud collaboration tools (xDrive, yBox, or zVCS) can help, but they don't cover everything. And if larger files need to be synchronized, it's slow even where Internet connection is fast.

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.
3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.
I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:
By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k
