The More You Automate, the Less You See: Hidden Pitfalls of AI Scientist Systems
AI scientist systems, capable of autonomously executing the full research workflow from hypothesis generation and experimentation to paper writing, hold significant potential for accelerating scientific discovery. However, the internal workflow of these systems have not been closely examined. This lack of scrutiny poses a risk of introducing flaws that could undermine the integrity, reliability, and trustworthiness of their research outputs. In this paper, we identify four potential failure mod…

Position: Intelligent Coding Systems Should Write Programs with Justifications
Intelligent coding systems are transforming software development by enabling users to specify code behavior in natural language. However, the opaque decision-making of AI-driven coders raises trust and usability concerns, particularly for non-expert users who cannot inspect low-level implementations. We argue that these systems should not only generate code but also produce clear, consistent justifications that bridge model reasoning and user understanding. To this end, we identify two critical…

The theory of open quantum systems is one of the most essential tools for the development of quantum technologies. A particular area of interest is in the optical response of solid state systems, where dissipation is introduced phenomenologically through the relaxation time approximation and its effects are usually gauged perturbatively. Analytical exact results for driven systems under this approximation are scarce and tipically pertain only to the stationary regime. Here, we obtain the analyt…

A distributed network architecture in which flying photons connect individual modules containing stationary atomic qubits is a promising approach for scaling up neutral-atom based quantum-computing platforms. We consider an all-fiber based platform consisting of nanofiber cavity QED systems interconnected via conventional optical fibers. Each nanofiber cavity is strongly coupled to multiple atoms through its evanescent field, and atom pairs within one cavity (local) or two distant cavities (rem…

AP-observation Automata for Abstraction-based Verification of Continuous-time Systems (Extended Version)
A key challenge in abstraction-based verification and control under complex specifications such as Linear Temporal Logic (LTL) is that abstract models retain significantly less information than their original systems. This issue is especially true for continuous-time systems, where the system state trajectories are split into intervals of discrete actions, and satisfaction of atomic propositions is abstracted to a whole time interval. To tackle this challenge, this work introduces a novel trans…

🤚 House at the lakeside with a few metres of private shoreline.
👉 House near a lake where all the shoreline is openly accessible.
Seriously, what's the point of closing up a lake like that, so that you can't even walk up to the shore?

Process Tensor Approaches to Non-Markovian Quantum Dynamics
The paradigm of considering open quantum systems -- i.e. focusing only on the system of interest, and treating the rest of the world as an effective environment -- has proven to be a highly effective way to understand a range of quantum systems, across areas of study such as quantum optics, cold atoms, superconducting qubits, and impurities in solid-state systems. A common approach in many of these contexts has been to consider simplified approaches based on the Born and Markov approximations. …

I've heard that some people are treating soup as a first dish, and then eat dinner proper.
I can't imagine how people can fit another meal after, say, a solid serving of pea soup.

Just released v3.1 of my account.
Bug fixes:
• changed the surname from "⛰" (U 26F0 mountain) to "🏔" (U 1F3D4 snow capped mountain), as the Android font displays the former as a plain triangle, and I looked like an "on demand" stop in a timetable.

Actually, it's completely incomprehensible to me — an atheist, an anticlerical and a leftist — how you could play disco polo music aloud under a church, during a mass.
Okay, I don't listen to disco polo at all. But I wouldn't play solid doom metal from Uganda either, even if "Where they gathered and suffered" seems to describe the situation accurately.
Okay, I don't play music in public at all. But I guess that's a matter of being cultured and respectful to others.

When you're waiting for the aerial map to load finally, the reception is good — and you finally realize that the Polish GUGiK aerial map ends just behind the border, and you need to switch.

Ich bin im Bundesrepublik Deutschland. Or something like that.

A problem: when you say "ich spreche Deutsch nicht", you're lying because you just said something in German.

I'm so tired that I guess I'm going to get up late tomorrow. Perhaps even at 6:30!

All of which was of the utmost importance for subsequent developments in the medicine of the mind. In its positivist incarnation, this was little more than the combination of the two experiences that classicism had juxtaposed without ever joining them together: a social, normative and dichotomous experience of madness that revolved entirely around the imperative of confinement, formulated in a style as simple as ‘yes or no’, ‘dangerous or harmless’, and ‘good or not good for confinement’, and a finely differentiated, qualitative, juridical experience, well aware of limits and degrees, which looked into all the aspects of the behaviour of the subject for the polymorphous incarnations that insanity might assume. The psychopathology of the nineteenth century (and perhaps our own too, even now) believes that it orients itself and takes its bearings in relation to a homo natura, or a normal man pre-existing all experience of mental illness. Such a man is in fact an invention, and if he is to be situated, it is not in a natural space, but in a system that identifies the socius to the subject of the law. Consequently a madman is not recognised as such because an illness has pushed him to the margins of normality, but because our culture situates him at the meeting point between the social decree of confinement and the juridical knowledge that evaluates the responsibility of individuals before the law. The ‘positive’ science of mental illness and the humanitarian sentiments that brought the mad back into the realm of the human were only possible once that synthesis had been solidly established. They could be said to form the concrete a priori of any psychopathology with scientific pretensions.

Can trolls live under viaducts in addition to bridges?

Polish people: "no, we can't shorten the work time, the economy will fall, there will be crying and gnashing of teeth!"
Also Polish people: "a new holiday? but of course, another day free of work is great news."
So, rather than 4-day work week we need to pursue 3-day weekend!

Yeah, so the GNU #make jobserver protocol is trivial, which can be a blessing and a curse. It puts the job management entirely on the clients, which means that they must reliably return job tokens, or otherwise the jobserver will be left with no jobs available and everything will hang. The make documentation is clear on this:
> Your tool should be sure to write back the tokens it read, even under error conditions. This includes not only errors in your tool but also outside influences such as interrupts (SIGINT), etc. You may want to install signal handlers to manage this write-back.
#NinjaBuild jobserver implementation may not handle this correctly, but fortunately it does. The irony is, it turns out that GNU make does not…

Totally normal night:
1. Scratching the cat.
2. The first continuous sleep, ending with a #nightmare. I've dreamt that my first return train was delayed, and I'm likely to be stuck in Głogów. On top of that, the train looked looked like a nightmare contraption, with a sequence of cubic compartments with no seats, and weirdly shaped holes in the walls instead of doors.
3. Toilet.
4. Checking blood sugar, just in case.
5. Looking for a spot in the bed that's free of sweat.
6. Scratching the cat.
7. A series of nightmares. The most interesting one was about getting up in the morning, in middle of a gale. The mains voltage was so low I couldn't turn the lights on, and instead of getting myself ready to go out, I was trying hard to measure it, helping myself with a flashlight.
My working theory is that these are side effects of my current medication. One week to go.

Is that sacrum – profanum thing when you hear organs from within a church, and disco polo from the building workers outside it?

Being me in the summer:
• no clothes left that can be removed
• keep cooling yourself using water
Being me in the fall:
• keep changing between summer and fall clothes (and carrying two sets on me)
• but at least I can cool myself using air
• regularly suffering a cold

The existence of Świdwin implies the existence of Świdloss.

On one hand, I feel that I should stay in the family house, because it'd be a waste to abandon it. On the other, living with neighbors regularly reminds me that I should live in the middle of a forest, separated from the nearest neighbor by at least 3 km of trees.

If someone wants to try Steve the Jobserver out, I've added a live ebuild in dev-build/steve. It installs the needed service files and suggests how to configure #Portage to use it as a global jobserver for all builds.

Doing #Gentoo these days feels like being a small cell of unpaid volunteers opposing the enshittification of software. On one side, we're put up against a horde of full-time corporate developers. On the other, against young ambitious volunteers with lots of free time. And both can rapidly spew tons of mediocre code, and doing things wrong is so much easier than doing things right.
(Just to be clear, I'm not saying every corporation or every youngster does things wrong — there are people who care on the other side too.)

Oh, the #PKP #InterCity seat reservation system. First, it doesn't let me finish the reservation because the seat I chose was just taken. Then, it doesn't let me do choose another seat because supposedly I have reservation at the time. It will reset it in a few hours, but still annoying.

Sequoia PGP exemplifies everything that's wrong about #RustLang (don't mean this against Sequoia). It features a bunch of different CLIs, which is a reasonable design.
If Sequoia were written in C, these CLIs would probably be using some shared library. If Sequoia were written in Python, they would probably use a shared Python package. However, it's written in Rust, so every CLI is a huge binary with its own copy of subset of shared Sequoia code, built separately:
