Even with the current state of AI, I still think WinDBG's Time Travel Debugging (TTD ) is the most time saving tech when reversing. Been using it for some years now, and I continue to be impressed by how my workflow has improved. 🤙

One of my favorite books!
2010: The 25th anniversary edition of Steven Levy's book "Hackers: Heroes of the Computer Revolution" was published. The cover art and tagline of the first edition published in 1984 make for a far superior cover.

This intro really captivated me with its vibe back in the day on DOS. Adlib music, sine-controlled amazing logo, starfield, and cool font for the scroller. Brought together with an awesome flair and style that, for me, is #TheScene .

I don't want to get into it, but I don't think Travis is quite right. I mean, the original 25million view tweet is full of fail and you should always assume Tavis is right .... ...but I'm seeing things a little differently. 🧵1/n
This strange tweet got >25k retweets. The author sounds confident, and he uses lots of hex and jargon. There are red flags though... like what's up with the DEI stuff, and who says "stack trace dump"? Let's take a closer look... 🧵1/n

Reading the latest book from @microzeit about the flame war between Amiga and the ST. Jumped right to the story, as told by Galahad. His way of writing is so good. Had to laugh, when his dad tells him; "all right, go pack that shit up and we'll take it back tomorrow". 😂👍
