Sometimes it takes more time to refute a gcc bug than confirm it. This week I spent most time on https://gcc.gnu.org/PR114872 where sagemath SIGSEGVed on some simple inputs.

Bug updates are a bit hard to read and are missing a bit of compiler-unrelated context. I wrote something more coherent in https://trofi.github.io/posts/312-the-sagemath-saga.html

When you read or write about #Python's init() method, which seems right to you:

Python 3.13 time.time() on Windows now has a resolution of 238 ns (10^-9) instead of 15.6 ms (10^-3): it's 65 500x more accurate! The feature was requested 11 years ago (2013)! Better late than never 😉 https://github.com/python/cpython/pull/116822

If you embed Python in C, please review the latest version of my PEP 741 "Python Configuration C API": https://peps.python.org/pep-0741/ Join the discussion at: https://discuss.python.org/t/pep-741-python-configuration-c-api-second-version/45403/31 I added PyConfig_Set() to set the runtime configuration and removed the Python API.

Just realized that 2024 is of a personal significance.

10 years ago, while depressed (didn't know it at the time) I decided to leave our life in Saskatoon and to move to Vancouver.

Started interviewing at >20s tech companies, got a job offer, and we moved.

First few years were such struggle, but overall moving to Vancouver has been life changing, and for the better.

May 17, 2014 was the date I arrived in Vancouver.

May 17, 2024 I'll be giving the opening remarks at PyCon US 2024.

My main text editor gvim is broken 🤕 It's very annoying. I'm not sure how to debug such issue.

I wrote a second version of my PEP 741: Python Configuration C API: https://peps.python.org/pep-0741/
Discussion: https://discuss.python.org/t/pep-741-python-configuration-c-api-second-version/45403
List use cases, use UTF-8, simpler error handling, API to get the init config, better doc, avoid preinitialization when possible, etc.

La programmation visuelle est et restera un marché de niche.
Le méta-verse est et restera un marché de niche.
La réalité virtuelle est et restera un marché de niche.
La réalité augmentée est et restera un marché de niche.
La blockchain est et restera un putain de scam.

Merci d'être venu à mon TED talk, c'est tout pour moi.

If you embed Python in your application, I'm looking for your feedback for my PEP 741 "Python Configuration C API": https://peps.python.org/pep-0741/ Tell me how you configure Python and if you are using or plan to use the stable ABI (limited C API). Also, reviews of the PEP are welcome 😁

I decided to get my two old desktop computers from the shelf. I don't recall how to connect the monitor: ah yes, VGA! First tower has no disk, the second is the one I'm looking for: 3 disks in RAID. It took me a while to remind the password. Last login in April 2020! Fedora 27!

Apparently, I'm only using a single computer for 4 years: my laptop. I have Nintendo Switch and PlayStation 5 to play video games. I don't know the purpose of these 2 bags full of old cables.

FOSDEM (Brussels, Belgium) event as usual: devroom full, wait 20 min in the hallway, get in and be kicked out. Sit down and try to listen to the live stream but the network loss many packets and has high lag. Wait 40 min, and get it this time.

By the way, the coffee machine doesn't accept cash and the credit card doesn't work (because of bad network?) 😭

I'm doing my best to limit how many Python issues I'm tracking. I learnt to unsubscribe often, but it comes back. Here are my notifications after a weekend. I went through 2 burnouts; still trying different things to make sure that contributing to Python remains fun 🥳

Now this is some cool glitch art right there 🤩

A malfunctioning information display about the next upcoming train at a platform of Düsseldorf main station. The lower half of the display (which is using white on blue pixels) is rapidly cycling through blocky noisy glitches.
