Newsletter #16 Understanding buffer overflows using Radare2 Jan 10 2020

Hello,

I’m back, I took a small break last week, no writing and no newsletter. I hope you had a delightful end of the holiday season. I’m ready to get back to my usual routine.

I’ve been travelling across time zones lately and thinking about time. Also, it’s the end of a decade, so we should talk about that. I’m not sure if you remember the Y2K problem, it was caused by representing the year on a date using only the last two digits. That meant that 1997 was represented only as 97, all fine there, but when you get to 2,000 you’ll get 00, and you won’t know if you were talking about 1900 or 2000.

Newsletter #15 - Using radare2 to patch a binary Dec 28 2019

Hello,

I hope that you had a good week, and if you celebrate Christmas, I hope you had a good one. I’ve been enjoying this week playing with binaries.

I sometimes feel like keeping up with high-level languages like Swift and JavaScript is very tiring. There is always something “new” and not all the time easy to grasp the implications of the changes. Anyways, it’s fun to see that the old assembly languages are still there and I can jump back to them after a few years and find them familiar.
