This might be a dumb question, but if anyone here has used by : is there any way to host more than one bot without using different subdomains?

I'd like to self-host more than just my Ralsei bot and, as far as I know, an easy way to do it would be to use different subdomains for each one. However, right now I only have access to neofox.dedyn.io and no way to register/use other subdomains through my DDNS (and I'd like to keep using that for the time being)

From what I understood through the docs there might be a chance to achieve what I'm thinking about by using a custom Bot.fetch() method instead of passing the built-in one to Deno/Bun, but I'm not too sure, and that's why I'm asking here first :neobot_think:

Salvatore Sanfilippo (@antirez) and Armin Ronacher (@mitsuhikoArmin Ronacher) both argue that reimplementation of 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.

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.

EDIT: I updated the fork to last commit before the AI slop. It's now relatively new.

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 Moneypoint now functions as a backup oil burner under emergency instruction, but it is no longer active in the wholesale electricity market.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.

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.

arxiv.org/abs/2603.04782

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.
