You can list a directory containing 8 million files! But not with ls.
You can list a directory containing 8 million files! But not with ls. I needed to list all files in a directory, but ls, find, and os.listdir all hung. This is my story. NOTE: there is no good reason that you should ever have 8 million files in the same directory, but if you do, this is your solution :-). TLDR: Write a C program that calls the syscall getdents directly, with a large buffer size, i
Operating Systems: Timeline and Family Tree
Includes about 1,240 operating systems so far Last updated: July 2025 In this post you'll find a family tree and timeline of operating systems. I have tried to include all operating systems, no matter how old or obscure. Of course, a complete list is virtually impossible, as there is no way to catalogue all the tiny hobby and embedded systems that may exist somewhere. Please also note that I only
DragonFlyBSD: DragonFly BSD
DragonFly 6.4.2 released DragonFly version 6.4.2 is released. The 6.4 series has hardware support for type-2 hypervisors with NVMM, an amdgpu driver, the experimental ability to remote-mount HAMMER2 volumes, and many other changes. 6.4.1 brings a number of bug fixes and driver additions. 6.4.2 adds fixes for the installer, ipv6, and for userland programs that create many subprocesses. Go to the 6.
The Story of the PING Program
Yes, it's true! I'm the author of ping for UNIX. Ping is a little thousand-line hack that I wrote in an evening which practically everyone seems to know about. :-) I named it after the sound that a sonar makes, inspired by the whole principle of echo-location. In college I'd done a lot of modeling of sonar and radar systems, so the "Cyberspace" analogy seemed very apt. It's exactly the same paradi

Pass: The Standard Unix Password Manager
Introducing pass Password management should be simple and follow Unix philosophy. With pass, each password lives inside of a gpg encrypted file whose filename is the title of the website or resource that requires the password. These encrypted files may be organized into meaningful folder hierarchies, copied from computer to computer, and, in general, manipulated using standard command line file ma
