Why a 15-pixel JPEG can look different in Chrome and Firefox
A tiny logo rendering differently leads into Skia and libjpeg-turbo, where Chrome can decode a JPEG directly at a fraction of its original size.
Shipping Fresh on Linux pushed its author toward building a tiny package manager
Fresh tried npm, Cargo, Nix, Flatpak, AppImage, AUR, deb and rpm before moving back toward a self-updating static binary.
This robot finger sees pressure in color instead of reconstructing touch
A mechanochromic skin turns deformation directly into colors a camera can read. The prototype reaches 100-micrometer resolution without a heavy reconstruction pipeline.
A 3 kB Windows game saved space by embedding its own virtual machine
For Langjam, Laurent Le Brun built a language, a VM and a shoot ’em up in an executable of roughly 3 kB. The constraint ends up shaping the game design too.
Why the same Chromium can use 900 MB or 278 MB of RAM depending on the counter
In our test, the same Chromium process tree showed about 899 MiB as summed RSS and 278 MiB as median PSS. memftprt is most useful for explaining why both figures can be true at once.
Kafka already stores the value. rpkv keeps only its address
rpkv stores only each key's partition and offset, then fetches the value from Kafka. A very young experiment that makes the storage-versus-latency tradeoff unusually visible.
Old YouTube videos become thumbnail experiments
Hardisk launched Reflare to generate and automatically test new thumbnails on old videos. The useful idea is treating a back catalogue as something that can still be worked on.
Giving a coding agent an LSP does not automatically make it better
Ian Barber tested LSPs, type checking and diagnostic timing with coding agents. The useful result is less about adding a tool than deciding when to enforce it.
Canario closes its source because generating a PR is cheaper than reviewing one
Raphael Amorim still maintains Rio as open source but is closing Canario. AI-generated PRs amplify an older problem: the human cost of review.
