Ever since I was 7 years old, I've been interested in computers, the Internet, and more recently, cybersecurity and social engineering.

I strive to become an excellent cybersecurity engineer. I'm always eager to learn and love meeting new people with similar interests. Feel free to drop me a DM!

For more information, please check out my personal blog: L1Cafe.blog.

Friendly reminder: is a great project to contribute your otherwise idle computing power.

boinc.berkeley.edu

You can set complex scheduling options, either by time of day, battery level, non-BOINC CPU usage, mouse and keyboard activity and so on. This way, it won't take up all your resources when you're compiling or playing videogames.

You can also configure it to only take a percentage of the CPU, a specific core count, or only allow it to run in bursts.

Contribute today!

I liked this article on the failures of the Boeing 737 Max. Very well written and detailed technical and administrative explanations on what went wrong.

My gf's learning html. Nobody told her that vim's a strange tool for genius programmers, so I just told her it was a normal tool, showed her insert and escape, then let her get on with it.

Half an hour later, I showed her another vim command.

Someone with almost zero education, who can't type properly, is programming in vim because nobody told her it was difficult. I know people who can program in Haskell who aren't sure if they can do vim.

there were some things i ddn't knew about raspberry pis:

"Linux runs on that ARM CPU, we know that, but we might be surprised to learn that Linux on this device is only a second class citizen. The GPU cores run a real time operating system called ThreadX. This operating system is closed source and rules the system without the open source Linux Kernel being aware of it."

and guess who bought the ThreadX operating system last april?

Another privacy win from Apple as they take a firm no-exceptions policy to all tracking practices in Safari.

Their newly-announced policy states that "tracking users 'without' consent... will [get you] kicked off the platform, treated like malware." forbes.com/sites/zakdoffman/20

This is the exact same reason why I switched to iPhone. iPhone SE too!

Great article, @kev, good job.

I ended up scrapping my progress and started from scratch. I'm testing and developing my blog's new design at testing.l1cafe.blog. I used mmistakes.github.io/jekyll-the as a base.

Let me know your thoughts!

Holy dang. Not only can the DMCA be used to bogusly take down someone's content, it can be used to get their address too.

@ultem Seems like this instance doesn't have this post for some reason, but yeah, that sounds like a good idea! I'm not an expert by any means but I'd love to have someone to play with.
