🦘 Jump into the repositories (git, mercurial…) of your filesystem with telescope.nvim, without any setup
Hi, it’s Clément! 👋
I’m currently working as a software engineer at Paxos in London, building exciting things with blockchains. Before that, I was part of the DDoS protection team at Cloudflare, using technologies like eBPF or Rust. Previously, I worked on non-intrusive performance analysis at the SnT, a lab part of the University of Luxembourg.
In my spare time, I enjoy writing and contributing to open-source programs. Most of that activity is visible on GitHub and Stackoverflow. I blog mainly about performance and tools I use (like NeoVim, Hugo or SQLite). Some of my writing made it to the front page of HackerNews or Lobsters, sparking fruitful discussions in the comments. See the blog roll for my curated selection of blogs. I sometimes talk in conferences.

Should I Compress My Initramfs?
TL;DR As a small start-up time optimization, you can pick the best suited compression algorithm for the initial ramdisk. The Initial Ramdisk When a Linux system boots, it needs to mount the root filesystem /. This may be relatively complicated, as it may be on a software RAID, on LVM, encrypted… To keep things manageable, an initial ramdisk can be used to get a small environment that has all the required modules and configuration to load the root filesystem....
Generating Snippets with LuaSnip in Neovim
TL;DR When you have many variations of the same snippet, one option is to generate those with Lua code. The complete example is at the end. I’ve recently moved to LuaSnip as my snippets plugin for Neovim. When I first started, I sticked to the simplest features of LuaSnip, in particular the SnipMate-like syntax for snippets. But I have now started to explore the more distinctive features of LuaSnip, like Lua-defined snippets....
Rust Default Values for Maintainability
TL;DR The Default trait can enhance the maintenability of your code. Default values for common types are listed at the end. A PR Review Recently, while reviewing a PR1, I noticed that part of the patch was introducing a new field to a struct: 1diff --git a/src/lib.rs b/src/lib.rs 2index eba9a3a..8619e06 100644 3--- a/src/lib.rs 4+++ b/src/lib.rs 5@@ -106,8 +108,9 @@ use std::{ 6 #[derive(Debug, PartialEq, Clone)] 7 pub struct M<'u> { 8 up: &'u str, 9 down: Option<&'u str>, 10+ foreign_key_check: bool, 11 } 12 13 impl<'u> M<'u> { 14@@ -137,8 +140,9 @@ impl<'u> M<'u> { 15 pub const fn up(sql: &'u str) -> Self { 16 Self { 17 up: sql, 18 down: None, 19+ foreign_key_check: false, 20 } 21 } That prompted me to reflect on the code I had initially written....
