I am grieving the barbarism that is going to unfurl from all this. People are going to die. Livelihoods gone. All to feed a corrupt kleptocracy.

I see every day up close how different it is from the first time around. There are no guardrails. A disaster. I’m sorry we have to live through this.

Spain’s high-speed trains aren’t just efficient, they have transformed people’s lives | MarΓ­a RamΓ­rez A fiasco like HS2 could never happen here – our fast train network is so popular that no Spanish government would dare give up on it, says journalist MarΓ­a RamΓ­rez

Spain spent 57 bln euros to build its entire high speed rail network.

Thanks to @jdidion.bsky.social for writing 99% of the tree-sitter grammar at the heart of this extension. I made some modifications to ensure compatibility with Zed's WASM plugin system and fixed a few bugs in the C lexer extension.

For those using WDL for their bioinformatic workflows: I wrote an extension for the @zed.dev code editor enabling syntax highlighting and integration with wdl-lsp. It also supports bash highlighting in command blocks.

Installable through the Zed extensions pane!

Still in beta, so possible minor API changes ... but our Suffix Array library (in Rust) is ready for business. Builds on lovely ideas in CaPS-SA from @robp.bsky.social.

Low mem construction. Spaced seeds. Optional crazy-low-mem search. More info on the horizon.

5/ In my experience, most of the time, you don’t need deep learning.

Often, simple methods like linear regression or random forests work well β€” especially for moderate-sized datasets.

Deep learning excels in image analysis & protein structure prediction.

It took me nearly a week to figure out why the BAM generated by a coworker gave different results than one that I generated myself 😱

To prevent this, we manually specified the fragment length mean with BWA's -I flag in future analyses.

If a downstream task filters improperly paired alignments (which is pretty common), it might filter accurate alignments that just happened to be in a batch with few other reads that aligned.
