VG will soon start adding headers to the GAF files it generates. The specifics are still uncertain, but if you maintain a GAF parser, it may be a good idea to skip lines starting with "@". Here is a draft specification for the vg flavor of GAF.

October 2025 batch of Kraken 2 indexes, including core_nt and many others, available: benlangmead.github.io/aws-indexes/k2
Coming soon to K2: a feature for querying many K2 indexes as though they're a single index. Highly useful if the index you want to query is too big to build and/or fit in RAM.

BTW @jbonfield.bsky.social someone edited Wikipedia's CRAM page a while back to add the unreferenced claim that it stands for Compressed Reference-oriented Alignment Map. Citation needed! As I recall, it officially doesn't stand for anything but is merely reminiscent of compression and references…

If you ever submit on bills, read legislation on legislation.govt.nz or use its RSS feeds to keep track of new bills, please tell the Parliamentary Counsel Office to make sure the new site keeps RSS. We shouldn't need to have an API key.

I'm a bit sad to see the PCO is going to end the Legislation.govt.nz RSS feeds, replacing them with an authenticated API.
www.legislation.govt.nz/news.aspx#rs...
APIs are great, but RSS is widely supported and unauthenticated - a much lower barrier to use than having to develop a custom API client.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Submitted on the Electoral Amendment Bill with 3 minutes to spare! Was reminded at the last minute that this bill has another go at disenfranchising prisoners (as has been shot down in the courts repeatedly)… so forgot to say that the deadline change likely won't speed up getting results anyway. 🫠

Watching talks on CMake while working out. I truly appreciate the work folks put in to keep trying to explain the "modern" CMake way. But in every case, I quit watching in disgust. CMake is an example of how to do everything wrong, and when cutting your losses is the best course of action.

Naively assumed that with the #InternetNZ election over, we wouldn't be hearing from the spaceman again. But I haven't been back there for long; perhaps he's been invested in spamming them with the same opinion over and over for longer than I realise…

Pleased that Debian 13 "trixie" has now been released. Prior to this, by my reckoning Debian was the only remaining major platform that did not package Cython 3.x in its system package repositories.
With Cython 3 available everywhere, pysam can reasonably require it and simplify a few things.

You can lead an open-source maintainer to water (provide a minimal test file exhibiting your bug, already named according to the style of their existing test files), but you can't make them drink (incorporate the new test case into their test suite).

If someone wanted to pay me to give bioinformatics format specifications the time and attention they deserve, I would be very pleased.
Otherwise, the work occurs as academic generosity in odd hours by people who are already oversubscribed in their day jobs.

I think that having a *well-specified* format is the most important part. Writing a binary parser is no harder than writing a text parser, as long as I know exactly what it is that I'm parsing (often it's much easier even). I agree regarding "official" parsers. One way to achieve that may be 1/2
