Algorithms for Modern Hardware
https://en.algorithmica.org/hpc/
This is an upcoming high performance computing book titled “Algorithms for Modern Hardware” by Sergey Slotin.
Its intended audience is everyone from performance engineers and practical algorithm researchers to undergraduate computer science students who have just finished an advanced algorithms course and want to learn more practical ways to speed up a program than by going from O(n log n) to O(n log log n).

蓝队的一万道纵深防御都比不上开发的一次真情流露，我觉得安全开发在防护设备走得太远，却连开发跟你说“前端没有调这个接口，没有安全问题”的情况都解决不了。虽然业务逻辑漏洞是不可计算问题，但你们J2EE领域就不能出一点secure by default的框架和方案吗
悲报：这两年经济不好，业务缩水挤走了很多弱智开发，新上的应用少了，洞也就跟着少了
喜报：vibe coding这块给大伙送来了vibe exploiting

不知道是不是错觉，主观感受上，明明电子数据取证和（toC/toB的）数据恢复是同一类技术，但居然是完全两个赛道两拨儿不同的人在干活，后者难度高反而更牛马。或者说，DF的程序正义和证据识别的部分，学习成本其实远比拆盘、扫扇区、重建、仿真乃至在生dump里捡文件系统/文件尸块拼起来要低得多；但是前者toG领域的商业价值远比后者在C/B收的费用要贵，竞赛氛围也更浓厚——然而当代很多取证比赛甚至连“手动利用Android Nday/错误配置越权读/data”之类的都不敢考，还是停留在E01怼到一键仿真，或是Volatility嗯扫内存dump上。

Which Font Makes the Best ⌶-Beam?
I spent three years trying to find out which typeface's capital "I" makes the best I-beam. Along the way I learned how fonts came to be and why I beams look the way they do.

Hi,
We've archived the MITRE CVE database. The CVE DB is free and open source on GitHub. However, we're providing a backup location for the data. We doubt it'll magically disintegrate in ash, but if it does we have a copy.

The United States government is using a fork of Signal called "TM SGNL". TM SGNL is (likely) produced by an Israeli firm (Smarsh) which is (or related to in some capacity) the Israel Defense Forces' Intelligence unit. Although these claims are based on self-described biographies of the creators of TM SGNL and publicly available information. Various journalists and media outlets have reported differently.
TM SGNL is a part of the Smarsh communication suite called TeleMessage hence TeleMessage Signal.
TM SGNL is not publicly available for download.
TM SGNL source code was leaked online May 3rd when an anonymous source tipped journalist Micah Flee about TM SGNL being available for download ... by accident. Smarsh left the source code to their application exposed because they used WordPress and misconfigured directory permissions which looked like so:
/wp-content/uploads/2024/12/Signal-iOS-main.zip
/wp-content/uploads/2024/12/Signal.zip
Journalist Micah Flee has made the source code available on GitHub. The source code also includes hardcoded credentials (and got knows what else)
You can read more about the leak, the contents of the leak, and you can find the link to the source code in the attached article below.
