#facebook is embedding tracking data inside photos you download.
I noticed a structural abnormality when looking at a hex dump of an image file from an unknown origin only to discover it contained what I now understand is an IPTC special instruction. Shocking level of tracking..
Can you guess when is the deadline?
Yes. It's this week. Tomorrow, actually.
Please kill me.
Thanks.

I just learned Eduard Punset passed away.
Many Spaniards know him as the host on a program called “Redes” on national television, with the intention of bringing science to everyone.
Punset was a very passionate and intelligent person, and even got involved in Spain’s politics in the 80s.
Thank you for all your efforts 🙏🏻, Punset. May you rest in peace, and may you be remembered for all eternity.
RIP 1936-2019
MUY IMPORTANTE - SE RUEGA DIFUSIÓN
Algún ser incivilizado se dedica a cortar los cables de frenos de los patinetes eléctricos compartidos. Esto es el colmo.
Si eres usuario de estos patinetes, COMPRUEBA LOS FRENOS ANTES DE DESBLOQUEAR, tu vida y la de los demás depende de ello.

Okay I don't understand what's going on.
This guy https://github.com/alirezasmr/Dragon-Book-Solutions/blob/master/ch05/5.4/5.4.md (first picture) claims to have solved an exercise, yet his solution pretty much looks recursive to the left to me anyway.
I solved it on the second picture. Am I correct or what?
Just finished my custom made keyboard. Starting small. Just a keypad. Cherry Red Silent. Looking good?

Ever since I deployed this on my server https://l1cafe.blog/2018/06/14/defeat-spammers, I have banned quite a few incoming addresses... And it's been barely a year.
So apparently I can make good-looking handwritten notes. Who would’ve known.
I’m helping scientists understand AIDS, cancer, and Zika. I donate my idle computing time so they can take advantage of my CPU and GPU. It costs me a few cents in electricity, and I help scientific efforts that take mankind forward. Care to join me? https://join.worldcommunitygrid.org?recruiterId=1012755
Hey @Tutanota, that’s a great way to avoid spam! Is this system developed in-house? I would love to learn how it works. Do you use Postfix?
This is from the #HackerOne #Hacker101 CTF challenge.
What does this mean? When can I expect an invitation? I've read their documentation at https://docs.hackerone.com/hackers/hacker101.html but they don't explain what private programs are...
