Command-line apps with Clojure and GraalVM: 300x better startup times
I am a fond Clojure user, and love to use it for both server-side projects and small command-line tools. I love its expressivity and concision, and I like th...

Native FreeBSD Kerberos/LDAP with FreeIPA/IDM
I want to make this clear in the first sentence because its biggest chance that people will read it – this article is entirely based on work done by Christian Hofstede-Kuhn (Larvitz) that wro…

Why linux doesn't have a "wheel" group
The wheel group is, perhaps, not widely used today, or is seen as “archaic” and irrelevant. Nothing could be further from the truth. The wheel group is a group which limits the number o…

Myths about USB NKRO and how USB HID works
A common myth about USB keyboards is that they can only support 6-key rollover, and not report more than 6 keys being pressed at a time. In fact, this is wholly untrue; the USB HID device class can support full N-key rollover (NKRO). While keyboards which purport to support USB NKRO are now common, some of them have…

Link-Time Optimisation (LTO)
I recently started exploring link-time optimisation (LTO), which I used to think was just a single boolean choice in the compilation and linking workflow, and perhaps it was like that a while ago… I’ve learned that these days, there are many different dimensions of LTO across compilers and linkers today and more…

Fun with -fsanitize=undefined and Picolibc
Both GCC and Clang support the -fsanitize=undefined flag which instruments the generated code to detect places where the program wanders into parts of the C language specification which are either undefined or implementation defined. Many of these are also common programming errors. It would be great if there were…

Why Intel is adding instructions to speed up non-volatile memory
The latest version of the Intel manual has a couple of new instructions for non-volatile storage, like SSDs . What's that about?

Picolibc – Libc for Embedded Systems
I wrote a couple of years ago about the troubles I had finding a good libc for embedded systems , and for the last year or so I've been using something I called 'newlib-nano', which was newlib with the stdio from avrlibc bolted on. That library has worked pretty well, and required very little work to ship.

Linux implementation of Homa, a protocol to replace TCP for low-latency RPC
Programming note: I will be taking a several week break from writing paper reviews for the summer. When we come back, I will be finishing off the papers from Usenix ATC and OSDI , then moving on to the great upcoming conferences (my non-exhaustive list is here ). As always, feel free to reach out on Twitter with…

Everything You Never Wanted to Know About Linker Script (2021)
Low level software usually has lots of .cc or .rs files. Even lower-level software, like your cryptography library, probably has .S containing assembly, my least favorite language for code review.
