Tuesday, February 13, 2024 By Pierre-Étienne Meunier An underappreciated aspect of Pijul is its backend, Sanakirja, which is easy to confuse with a mere key-value store.

In this article we'll discuss how to achieve the speedup below for UTF-8 to UTF-16 conversion, using the RISC-V Vector extension. I excluded the plain ASCII case from the graph above because it made the other results less readable, the speedup was: 8x for C908, and 11x for C920. More comprehensive measurements are a...

Frame pointers vs DWARF – my verdict

A couple of weeks ago I wrote a blog posting here about Fedora having frame pointers (LWN backgrounder, HN thread). I made some mistakes in that blog posting and retracted it, but I wasn’t wrong about the conclusions, just wrong about how I reached them. Frame pointers are much better than DWARF.

Running shared cloud infrastructure is tricky. One challenge that we have at DigitalOcean is striking the right balance between packing as many Droplets as possible onto our servers, and making sure those Droplets remain performant and available.

What if I told you that someone hid some weights in your shoes?Not massive weights that would make your shoes unliftable, but many tiny lead balls, hidden everywhere. Just enough lead balls so you can still walk, but the shoes feel heavier and walking feels harder today and, oh wow, I’m tired, this short walk really...
