Using gRPC for (local) inter-process communication (2021)
Using a full-featured RPC framework for IPC seems like overkill when the processes run on the same machine. However, if your project anyway exposes RPCs for public APIs or would benefit from a schema-based serialisation layer it makes sense to use only one tool that combines these—also for IPC. Microservices for…

Quicksort with Jenkins for fun and no profit
I first encountered Jenkins in 2007 while contributing to the Apache Nutch project. It was called Hudson back then. The nightly builds for the project ran on Hudson at that time. I remember sifting through my emails and reviewing build result notifications to keep an eye on the patches that got merged into the trunk…

Fast Shadow Stacks for Go
tl;dr : Software shadow stacks could deliver up to 8x faster stack trace capturing in the Go runtime when compared to the frame pointer unwinding that landed in go1.21. This doesn’t mean that this idea should escape from the laboratory right away, but it offers a fun glimpse into a potential future of hardware…

Emacs commands I got by with for years
As far as I know, the next meeting of EmacsATX, the Austin Emacs Meetup group , has a planned topic: Org mode . I was going to make a post about the common Org functions I use frequently, but I thought that I should start with common commands I used for generic Emacs when I started using it more than twenty years ago…

Taming floating-point sums
Suppose you have an array of floating-point numbers, and wish to sum them. You might naively think you can simply add them, e.g. in Rust:

Zero or Sign Extend
A while back I had to deal with a bit-packed format that contained a list of integer values encoded in one of a pre-defined sets of bit widths, where both the allowed bit widths and the signed-ness…

Why it's hard to trust software, but you mostly have to anyway
My long-time collaborator Richard Barnes [1] used to say that "in security, trust is a four letter word" , and yet the dominant experience of using any software-based system—which is, you know, pretty much anything electronic—is trusting the manufacturer. Not only is there no meaningful way to determine what software…

A beginner's guide to constant-time cryptography (2017)
For programmers new to cryptography, there are plenty of “known unknowns” – unfamiliar terms like “elliptic curves” and “random oracles”, and unnecessarily long acronyms (“RSASSA-PKCS-v1_5”, like really?). But what really gives cryptography its reputation is the unknown unknowns. The things that catch even experienced…

The C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…
