Obsidian for markdown and support for mermaid together with a coding agent has been absolutely wonderful for creating timeplans. The agent pulling data from multiple excel files and creating a unified plan. Also having it update the mermaid Gant charts as people fire off new things in meetings

While I built multiple applications and packages at home and work, this is the first time I pushed something to pypi!🥳 It was inspired by this episode of @pythonbytes.fm: pythonbytes.fm/episodes/sho... Where Michael said someone should build a package based on a blog post covered. Well here we go!

I think this is a really good point from @jamellebouie.net. I find outsourcing the formation of my view on a topic to an LLM a scary proposition. This is also why I'm a bit wary around coding assistants. When am I outsourcing so much of my thinking that it impacts my understanding of the problem?

Thanks to @willmcgugan.bsky.social and the textualize team for this time. Textual seems to be a TUI library that is second to none, python or otherwise. I'm sad that the company didn't work out, but glad that you gave it a go as textual made me fall in love with the terminal applications

Seeing PEP-735, Dependency Groups, included in the latest version pip makes me really happy! With both uv and pip supporting them I'm pretty sure I can move away completely from requirements.txt 🥳

I would generally agree with this perspective on LLMs. To me the aggressive stance against there usefulness looks more like a counter reaction against the hype. Are they as useful as the hype-side tries to tell you, absolutely not. Are they useless, also no.

Tried out asdf yesterday, mainly to manage erlang and elixir. Feels like it would have been nice if plugins could manage build dependencies for you. Copy-pasting the install commands from the readme obviously wasn't hard, but increased the friction slightly

Beside the changing table we have a box of baby socks. I found 3 socks, non of which where equal to the others. Looking around I found another one, which obviously didn't match the other 3. I gave up and started on a new pair, guess I will find 5 non-matching socks the next time ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

Came across a poll on linked-in on how to create private fields and methods in Python. Almost 50% of the over 1100 respondents picked __my_var. The technically correct answer of "private, what do you mean private?" didn't exist 🧐 and _my_var, what I believe is industry practice was way lower 🤔

I felt like I was guided through todays #adventofcode. From the start I knew what bart 2 would be, but the problem felt difficult. So I focused on doing that part and when I came to the second part I could see the solution very clearly. Just build out from the checking code and problem solved 😊

I just want to add that this doesn't make me a die hard fan of DRY (Don't repeat yourself). While generally pretty good advice, it can also lead to you implementing the wrong abstractions. This often manifest in functions with different modalities. I personally like WET (Write everything twice)

Me in the middle of solving #adventofcode: "I will just copy-paste and change this code, that will be much quicker" Me when debugging my solution: "Damn it, I missed to fix this in both places"

For anyone coming across the "ghost engineer" stuff, this is a great take on it. One key thing, currently there is no published paper on the actual ghost engineer things, only a code quality metric predictor thing that they seemed to use for it. Very important difference. youtu.be/_a_Vz2ytVCQ?...

EffVer: Version your code by the effort required to upgrade

Version numbers are hard to get right. Semantic Versioning (SemVer) communicates backward compatibility via version numbers which often lead to a false sense of security and broken promises.

10th anniversary Journey thread, recreated: I was the art director of thatgamecompany's Journey. It set the course of my career and my art. I'm forever thankful to the community of players and their incredible love for the game. This is a thread comparing early dev images and how things shipped.

The intro title shot from the PS3 game Journey. This is from the finished game. The title "Journey" is displayed above a distant mountain, with the player character seeing it from atop a sand dune.

The intro title shot from a work in progress version of Journey. The title's font is different, the composition is asymmetrical, and the distant mountain is not as tall as the final version.

My initial sketch for the title shot for the game Journey. A simple, small line drawing featuring the player character in the foreground and the mountain in the distance.
