There's no functor like Hom

Update for the blue sky world. In the time passed since my last Skeets I have:
- Found a job as a #C++ developer. The codebase is dogshit but me and another colleague are trying to improve it bit by bit
- Haven't done much cyber security related
- Started learning #Haskell and having a lot of fun

(please re-post for reach - thank you!)
Learned a cool new Linux trick? Know an interesting quirk in a network protocol? Or have something else to share?

Write a 1-page article for the #6 issue of Paged Out! :)

Soft deadline is Feb 1st.

You go all the way to infect a popular npm package and then deploy xmrig

my blog now has a dark mode so at night you dont hurt your eyes anymore

found that 44 percent of the top 100 most-followed accounts on Bluesky had at least one “doppelganger,”

That isn't how statistics works, you don't take 100 accounts and see that 44 of them follow some property and then say 44 percent

My latest blog post is live! nastystereo.com/security/cro...

Read how to send a cross-site POST without including a Content-Type header (without CORS). It even works with navigator.sendBeacon

i added a skeet button to my blog to allow people to easily share content on Bluesky. See it for example here lucabtz.com/blog/pwning-...

Someone needs to make an app to make it easy to follow people you follow on X also on bluesky. Or if it exists already I would like to know the name

turns out BlueSky is pretty good: it is similar to what Twitter used to be before becoming X.

X sadly became a MAGA place, my For You page is unusable, filled with posts of Musk and other MAGA accounts which I don't care to read.

I wish my mutuals and the accounts I follow there would move here

finally a reasonable take

Optimist: the cup is half full
Pessimist: The cup is half empty
Topologist: the cup is a donut

Why on earth did I decide to attempt a pwnable.tw challenge with only 29 solves. Been reversing for a while and cant really see the bug. Various parts of the code look fishy, but then they also seem safe

Hello I'm new to Blue Sky, I'm a theoretical physics master who is switching to cyber security because I've always been passionate about computers. I blog monthly here lucabtz.com about any projects I'm onto.

Looking to connect with some people to make my feed more interesting.
