Lossless Float Image Compression
Back in 2021 I looked at OpenEXR lossless compression options (and I think my findings led a change of the default zip compression level , as well as change of the compression library from zlib to libdeflate . Yay blogging about things!) . Then in 2023 I looked at losslessly compressing a bunch of floating point data…

The importance of offtopic
My first big job in the industry had me as one of two people in Warsaw, with the rest of the team in Oslo. I’ve never seen any of my Norwegian co-workers at that point, but one the first pieces of direct feedback I got from my manager was: “the teammembers like you; they feel like you’re part of the team.”

Generic Containers in C: Safe Division Using Maybe
Martin Uecker, 2025-08-10 I discuss the implementation of type and bounds safe generic containers in C. Previously, I discussed a span type , bounds checking using arrays . and a a vector type . This time, I will discuss maybe inspired by Haskell. This type can used to return a value that may not exist, e.g. because…

Implicit ODE solvers are not universally more robust than explicit ODE solvers
A very common adage in ODE solvers is that if you run into trouble with an explicit method, usually some explicit Runge-Kutta method like RK4, then you should try an implicit method. Implicit methods, because they are doing more work, solving an implicit system via a Newton method having “better” stability, should be…
