We built a CTF challenge designed to be painful to reverse engineer. Then an AI agent solved it in 6 minutes.

Hebrew by Inbal Apr 23

Every method out there teaches Hebrew as if you already think in Hebrew.

I built mine meeting you where you actually are.

Because after decades of living and working professionally in both languages, I know exactly where English speakers hit the wall.

Zatanna — Turn software workflows into reliable APIs for AI agents

Zatanna maps human-only software workflows and exposes them as reliable APIs your AI agents and internal tools can call in production. No browser automation scripts to maintain.

If someone started an #automotive #nonprofit to provide #resources for techs and specialists like key codes, #continuingeducation (with a focus on electrical, programming/coding, embedded systems/networks, and all the stuff you NEED to know for new cars) case studies, #networking events, free classes/videos, #mentorship, would any #embeddedsystems or #car people be interested? Basically building a better #NASTF or one not dependent on dealerships, because they'd #reverseengineer that shit first

Massive thanks to @chrishuck for posting about the @FreeCAD Detessellate workbench... it's super super useful! Just used it to successfully #reverseengineer a deceptively complex seal design! (Everything tapers!)

w.social invite code

So regarding that new EU social network (which is said to be decentralized but unclear if that implies ActivityPub which would make it more relevant in my book); entering a string in the "invitation code" and clicking "continue" does not result in an XHR request to the server and there's a lot of JS on the page to handle the invitation code. This implies the code is checked in the browser so the correct code(s) is somewhere in the JavaScript. So it should be possible to reverse-engineer it, […]

feel like i'm losing my mind, i was under the impression that lc_function_start contents were all uleb128 values, but i've got a valid arm64 macho binary that has different set of offsets than what i would decode with that approach and im not sure why. hopper gives me the right offsets but my code does not, but that same code works fine on other binaries too. this is my uleb128 implementation: https://github.com/samdmarshall/machodiff/blob/master/machodiff/reader.c#L14 #macdev #macho #mach #dwarf #iosdev #apple #binary #re #reverseengineer
