EDIT 4: We rolled back to VIm 9.1.0, no more AI slop. We kept our EVi changes too!!!

EDIT 3: This is really bad, we've found AI slop from before the AI commits we knew of. Please see codeberg.org/NerdNextDoor/evi/. We're currently discussing the best way to proceed over IRC.

EDIT 2: I forgot to update this, the project is called EVi now.

hard-forked vim at release 9.1.0 (Jan 2024)

maybe we can get a group of people behind this??

Fuck AI.

Ireland shuts last coal plant, becomes 15th coal-free country in Europe

Moneypoint in County Clare, Ireland, joins the ranks of other European nations exiting coal by shutting off power generation at its sole remaining coal plant. Industry observers say Ireland’s increased renewable energy generation in recent years, particularly in wind, has contributed to this milestone. Moneypoint now functions as a backup oil burner under emergency instruction, but it is no longer active in the wholesale electricity market.

RE: mastodon.social/@bagder/116200

💯 I gave them quite a bit of feedback while I was on the Python Software Foundation board. While a few typo-level fixes were implemented, all/most concerns were completely ignored.

This is why I struggle to take these orgs seriously.

Salvatore Sanfilippo (antirez) and Armin Ronacher (mitsuhiko) both argue that AI reimplementation of copyleft libraries is fine. Their legal reasoning might be correct. That's not the point. Legal and legitimate are different things—and both pieces quietly assume otherwise.

I stumbled on an interesting white paper, "Unlocking Python's Cores: Hardware Usage and Energy Implications of Removing the GIL."

Python's energy impact isn't as high on my bingo card, but I thought it was worth sharing because it's relevant to many of you.

Unlocking Python's Cores: Hardware Usage and Energy Implications of Removing the GIL

Python's Global Interpreter Lock prevents execution on more than one CPU core at the same time, even when multiple threads are used. However, starting with Python 3.13 an experimental build allows disabling the GIL. While prior work has examined speedup implications of this disabling, the effects on energy consumption and hardware utilization have received less attention. This study measures execution time, CPU utilization, memory usage, and energy consumption using four workload categories: NumPy-based, sequential kernels, threaded numerical workloads, and threaded object workloads, comparing GIL and free-threaded builds of Python 3.14.2. The results highlight a trade-off. For parallelizable workloads operating on independent data, the free-threaded build reduces execution time by up to 4 times, with a proportional reduction in energy consumption, and effective multi-core utilization, at the cost of an increase in memory usage. In contrast, sequential workloads do not benefit from removing the GIL and instead show a 13-43% increase in energy consumption. Similarly, workloads where threads frequently access and modify the same objects show reduced improvements or even degradation due to lock contention. Across all workloads, energy consumption is proportional to execution time, indicating that disabling the GIL does not significantly affect power consumption, even when CPU utilization increases. When it comes to memory, the no-GIL build shows a general increase, more visible in virtual memory than in physical memory. This increase is primarily attributed to per-object locking, additional thread-safety mechanisms in the runtime, and the adoption of a new memory allocator. These findings suggest that Python's no-GIL build is not a universal improvement. Developers should evaluate whether their workload can effectively benefit from parallel execution before adoption.

“When you create a law, you have to think about what a future government could do with those powers."

Ministers would have unilateral powers to lock what they see as 'harmful' behind digital ID checks.

This could end up being used on LGBTQ+ and reproductive health content.

Every day I’m more convinced that the Fediverse’s slow mainstream adoption isn’t really about usability.

People say it’s because it’s hard to join, the terms are confusing, or the apps aren’t polished enough. Maybe a little. But honestly… look at the platforms people already use.

Finding anything on LinkedIn is painful.
Trying to locate the original video on TikTok is a scavenger hunt.
Facebook is still full of weird bugs and odd UI choices.
Instagram hides posts behind algorithms.
Twitter/X constantly changes the rules of engagement.

None of these platforms are exactly “easy.”

People stay because their friends are there. Because the big creators are there. Because that’s where the conversation already lives.

And, if we’re honest, because these platforms are engineered around a very effective reward loop: notifications, likes, infinite scroll. A dopamine machine. You learn the confusing terms and awkward interfaces because there’s a constant reward for doing so.

So yes, making the Fediverse easier to join absolutely helps.

But what would help even more is something simpler:
more mainstream, recognizable, official accounts showing up here.

That’s how networks grow.
People follow people not platforms.

I've seen people claiming - with a straight face - that mechanical refactoring is a good use-case for LLM-based tools. Well, sed was developed in 1974 and - according to Wikipedia - first shipped in UNIX version 7 in 1979. On modern machines it can process files at speeds of several GB/s and will not randomly introduce errors while processing them. It doesn't cost billions, a subscription or internet access. It's there on your machine, fully documented. What are we even talking about?
