Pinned toot

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!

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

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.

"Okay, here's the scenario. You are a crew member on a starship."
"Space travel is slow, you'll be stuck with your crewmates a long time."
"So we must get along."
"Yes. Communicate, listen, share limited resources."
"I can do that. What's the starship called?"

I really needed a logo for Kydara. This is what I came up with. Simple and sharp. What do you think?

Hui, and more fancy open source software:

Advanced grammar help, sponsored by the European Union, published as free software. And free to use in the basic configuration, with some additional, more business focused tools which are available at a higher price tier.

During these times of quarantines and self-isolation, I'm challenging all my contacts with Apple Watch to a 7-day competition. Send me your iCloud e-mail address or phone number, and I will send you the invitation.

I have been struggling with this for a while, and can't manage to find an explanation or a fix for it. My Alpine machine isn't running crontabs for non-root users. Why does this happen? Also, how can I make a script in root's crontab be run as a different user?

There's a way to unblock a reported user? I would like to follow a user from that someone reported and blocked of

I've noticed some of my .one domains failing to resolve intermittently. Has any of you experienced the same? It's pretty weird. Huge, very easy to exploit MediaTek vulnerability leaves Android devices completely unprotected, and it is being used in the wild right now.

Did you know that, before being able to swap out the optical apparatus of the Hubble telescope, a temporary fix was applied using the Fourier Transform by means of modelling the image transformation on Earth, and just reversing it?

Computer Science is fascinating indeed.

If you know any authors, please encourage them to adopt one of the models on 馃槉

16-22 really *really* irk me because I see peers believing in those every damn day and the instructors don't tell them any differently

My cellphone carrier doesn't offer a free API for programmatically sending SMS messages. Or at least not for free, they do have an option for businesses but it's extremely expensive.

I have an old Android phone I could keep in a drawer with a SIM card to act as an SMS gateway. My question is: Is there a service that allows me to expose an HTTP REST endpoint for (securely) sending (maybe receiving too) SMS messages? Better if it's FOSS. Thanks!
