From the article, it seems they using a clause allowing them to terminate the contract after transfer of ownership.

This clause probably has a expiry date and they are saying “we are trying not to be jerks here by waiting until the last second to trigger it”.

As long as you are not running a paid bounty program. Otherwise now you are getting 40 per day.

It doesn’t make sense to do that, hardware deprecates in 5years (it used to be 3) and is currently very expensive. So by using this approach you double the average cost of hardware per unit of compute completed.

If there wasn’t such a hardware squeeze and electricity was a higher percentage of the cost, yes, it would have made sense.

There are rumours that Polish GROM has been taking “vacations” in Ukraine. As in “we cannot officially approve your presence there but we won’t stop you either”, from the government.

Because Shahed 131/136 are large, way larger than surveillance drone/quadcopter. We are talking 2-3m wingspans and 130-200kg launch mass.

Kubuxu — Sun, 26 Jul 2026 10:42:46 +0000

I use SQLite history to have context aware line suggestion in my shell. So the command that gets ghost displayed (and can be expanded with right arrow) depends on the current working directory, its parents and recency. This is fast enough using SQLite to just dump all commands into it and query on each typed letter.

The DB is at this point 10years old. I use it to evaluate my work habits and patterns. More recently I have started transitioning to a different shell and I used it to move only the functions and aliases I still use, instead of the full collection.

> So you read an article "China disappears random person" and then at the end you click a button and bet whether that person is alive or dead or whatever.

Congratulations, you just created a murder market. Create “Is person X dead?”, and put a large limit order buying No. Anyone with means can capitalise on it by fulfilling the physical obligation of the market and buying up the limit order. Don’t create the murder market.

It would be a stupid thing to do given the trail, bit it gives the person ordering it sort of plausible deniability.

I have TDD flow working as a part of my tasks structuring and then task completion. There are separate tasks for making the tests and for implementing. The agent which implements is told to pick up only the first available task, which will be “write tests task”, it reliably does so. I just needed to add how it should mark tests as skipped because it’s been conflicting with quality gates.

Kubuxu — Fri, 10 Apr 2026 03:43:18 +0000

That somewhat existed in servers in the past, my R720xd had RAM mirroring mode. IDK if it used it for reducing latency, but you could take out a stick and the server would continue running as normal and report an alarm in iDRAC.

Just try using Claude with API for an hour and you will see that the subscriptions are definitely not profitable (unless they percent off “partying but dormant” is very high).

A paper on the same topic: On the Expressiveness of Softmax Attention: A Recurrent Neural Network Perspective, Gabriel Mongaras, Eric C. Larson, https://arxiv.org/abs/2507.23632

Video presentation if someone prefers it: https://www.youtube.com/watch?v=PN3nYBowSvM

Linear attention is a first-degree approximation of Softmax attention, and model performance gets better as you increase the degree of the Taylor approximation.

I'm thinking about adapting an existing model to Taylor-approximated attention. I think it should be possible with some model surgery and rehabilitation training.

Definitely agreed, that is what I do as well. At that point you have good understanding of that code, which is in contrast to what the post I responded suggests.

I don’t see how I would feel comfortable pushing the current output of LLMs into high-stakes production (think SLAs, SRE).

Understanding of the code in these situation is more important than the code/feature existing.

For 8+ bays you just need a SAS HBA card and one free PCI-E slot. Not to mention that many motherboards will have 6+ SATA ports already.

If anything, 2nd hand AMD gaming rigs make more sense than old servers. I say that as someone with always off r720xd at home due to noise and heat. It was fun when I bought it during winter years ago, until summer came.

New comment by Kubuxu in "Disrupting the DRAM roadmap with capacitor-less IGZO-DRAM technology"

Kubuxu — Wed, 10 Sep 2025 03:00:58 +0000

Traditional CMOS D-flipflop takes 16 transistors, SRAM cell takes 6 (two looped inverters and two data-line selection transistors).

The capacitor in DRAM is usually realised as an enlarged gate of a transistor AFAIK.
