I implemented a CPU and RAM. In Javascript. For a blog.

Some days are harder than others. But at least today was a beautiful sunrise with the Moon and Venus
Just before the sunrise. Pink and yellow colors under the moon and venus in Lille (french city)

@imartayan.bsky.social pronounced my name incorrectly. Is it wrong of me to hope that generations of students and bioinformaticians to come will continue to do so? www.youtube.com/watch?v=35Yg...

On the number of $k$-mers admitting a given lexicographical minimizer
The minimizer of a word of size $k$ (a $k$-mer) is defined as its smallest substring of size $m$ (with $m\leq k$), according to some ordering on $m$-mers. minimizers have been used in bioinformatics -...

I extended my fast-minimizers blogpost with the lastest results, providing proper deduplicated minimizers and super-k-mers in 1.65ns/kmer, and canonical kmers in 1.90ns/kmer. Or 5.4s and 6.4s respectively on a human genome. Let me know if you want to use this :) curiouscoding.nl/posts/fast-m...

Nice result to end the day (night*): After discussions with @imartayan.bsky.social, the SIMD minimizer code now also does proper canonical (revcomp) minimizers: ~1ns/bp for fwd minis +0.4ns/bp with collect and dedup +0.6ns/bp with canonical hashes. Super happy how it's only 2x slower in the end!

Very excited to see Movi (by @mohsenzakeri.bsky.social) now out in iScience: www.cell.com/iscience/ful.... Movi builds on the "move structure" pangenome index, a compressed full-text index and close cousin to r-index. Compared to r-index, the move structure is simpler and more cache-efficient.

The dpt started a new Primer Method session! The meeting will take place every Monday for 2 months. Today we had @hu-asch.bsky.social discussing interaction effect testing in linear models. Next week @yoann.bsky.social will talk about computing, storing and querying de Bruijn Graph from k-mer!

Salut les amis du ciel bleu. Si demain vous ne faites rien entre 15h et 19h, vous êtes les bienvenus à la Tréso à Malakoff pour jouer à la gameboy avec mon asso Benji et moi. Il paraît même qu'on y fera un tournoi de Tetris avec des cable link !
