Seems like someone at #microsoft used the wrong .env or something, just got a debug notification from the Defender for Android app 😆

I have OFFICIALLY handed in my bachelor's thesis 🥳

Super relieved to finally be done with this, as fun as it was doing stuff, writing for a specific page count instead of writing until all the information has been presented is just really not my thing.

Jailbreak using kok3shi9 worked like a charm, first try.
I bought an iPad 2 (A1396) for 10,50€ off ebay (Charger included!). I figured there's got to be some use for a 1 GHz core with a Wi-Fi antenna and touch display attached. I'll be using this thread to document things as I figure this all out.

Roughly two years ago I hacked together a small tool to automatically download the
#windows #docker images, extract the ntdll.dll from them and extract the #syscall numbers for that Windows version. This can be used for #shellcode and other #malware dev activities.

All the data is either available in the HTML tables, or as a JSON by appending ?format=json to the URL.

Because it's just been redeployed, it's re-downloading all the images, so it will take a few hours until more Windows versions are indexed. It's now indexed more than 200 different version of ntdll.dll :)

I'm working on a #blog post about measuring the roundness (and sameness) of polygons (because I got nerd sniped and need to prove a point).

To measure the "correctness" of the different measures, I'd like to know: Which of these two objects do you think are more "round" (whatever that may mean to you)?

The poll is right below this post, unfortunately Mastodon doesn't support Polls with Media Attachments right now.

Well, another 5 hours later I managed to port it again, this time to Web Assembly + Rust. And tada, factorizing polyomials over F128 in ~200ms in the browser 🎉

Now all that's left is to build the demos and actually write the article I have in mind...​

A story in three parts
