Do any suppliers expose about their stock, so I can query it at home?

I'm looking for the most efficient but still cheap middle-powered warm-white in some form factors.

@dcz@fosstodon.org avatar

@deshipu Close, because I can query it, but the critical part is "at home". In the case of LED

I can filter on luminosity, angle, and current, but I actually want to sort by efficiency: LumAnAn/Vol/Cur.

If I could dump the database, that'd be easy, but I don't see away to do that.

Trying to write a exploration tool. I've been putting it away because GUIs are painful.

Now trying again: looks fine, but not clear how to style tables.

Maybe I'll go back to . The idea of callbacks can be annoying, but at least styling is a breeze. You can even put widgets inside cells!

It turns out that making GUI is hard.

@slint My other problem with slint table was that the process used like 30% CPU when idle. Debug build or not, no interaction should mean no processing.

I'm not sure if that is intended, should I file a bug?

Remember that automation is not about removing effort, it's all about packaging it in convenient ways so that it can be stored and moved around. Sometimes you get some savings due to bunching up of similar things or economy of scale, but most of the time the perceived savings are simply because the real effort is hidden away or deferred. Whether it's Jacquard looms, language models, github actions, self-driving cars, or robot food delivery, someone is doing (or has done, or will do) the work.

dcz,
@dcz@fosstodon.org avatar

@deshipu It is about removing effort. In the case of jacquard loom, someone put in the effort to produce the cards, and the next person doesn't have to do it by hand. And the next one. And the next one. The effort of N people is replaced by 1.

I'm not sure if the others are breaking even, but with time I bet they will.

dcz,
@dcz@fosstodon.org avatar

@deshipu Of course. My bet is that this new effort is typically smaller than the old effort was. Have you tried to sew by hand?
Maybe not automation by your definition, but the sewing machine saves hours and hours of work. If I was serious about sewing, I'd build one just to save my own time.

In another example, using machines for farming made it so that there's less than 90% of the population dedicated to food production.

dcz,
@dcz@fosstodon.org avatar

@deshipu You're completely right. Entropy ensures that no matter what happens, it happens because of some energy being turned into heat.

But I find this definition useless for considering social situations. Here what matters is the subjective effort expended by agents.

dcz,
@dcz@fosstodon.org avatar

@deshipu I agree with the above post, but you're also making a very bold claim I disagree with: that there's some "effort preservation" law.

I think that's an extraordinary claim and it requires extraordinary evidence.

As a basic example, we have many different sources of electrical energy available, with different costs and same labor production: coal, solar, nuclear, water. I'm not going to believe so easily that the ultimate effort per unit of benefit of each is the same.

dcz,
@dcz@fosstodon.org avatar

@deshipu That's why I chose electricity: the unit of electrical benefit can be compared across all of the sources very easily (Joule, Wh). So that's one variable less, it's the "damage" that's still a question, and I'm saying that it varies.

Unless all the sources are net negative (even solar and nuclear), then effort can be saved.

dcz,
@dcz@fosstodon.org avatar

@deshipu That's true, but I chose the example because given two separate sources and used for the same purpose, you get vastly different ratios of input to output effort. And with solar energy, over long enough time, I don't see how solar fails to save effort if it's used to, say, operate a washing machine.

dcz,
@dcz@fosstodon.org avatar

@deshipu True, you did write that.

But then it's really easy to say what things are about: the intention of the washing machine is "about" removing the effort of washing, not "about" expending the resources needed to operate it.

I think you're crossing streams between intention and effect here.

I'll talk about how "My files are a mess!", and how it will stay this way unless we achieve a collective enlightenment.

@publicvoit Reading a bit more of your work (like application-centric systems), I definitely want to have a chat with you. Are you visiting Germany any time soon?

Emotional rollercoaster of starting new projects:

  • This is cool
  • I've spent 18 hours on this
  • This is awful
  • I'm awful
  • The world is awful
  • This is cool (goto 1)
  • ... weeks pass_
  • Wow this is great.
  • Almost done
  • lose interest
  • Project abandonned

@thelinuxcast I hate this, and this keeps happening.

At least I can fix #qtcreator by manually tweaking the style (but why provide "system" if it doesn't work?)

The feeling when 87.5% of the discussion under your contribution is about : unreliable CI and insignificant .

Congrats, the project has created a barrier to entry for anyone who hasn't been into it for years already.

Hint: give everyone a freaking that satisfies your needs and let us move on to actual work, without having to redo the same stuff 8 times. Sheesh.

dcz,
@dcz@fosstodon.org avatar

@deshipu Well, you mentioned effoet, but effort is not knowledge. Then you repeated "You can convey a lot of knowledge" but you skipped what exactly.

Sorry if you feel ignored, I am genuinely curious.

dcz,
@dcz@fosstodon.org avatar

@deshipu Well, i run it through a test suite, and read it carefully for architectural descriptions, and make sure that naming is fine.

If I have to reverse-engineer it to understand, then I take off quality points.

If I can't read it due to formatting, I guess I'd run it through a linter, but I don't think it would affect my impression of quality. Hence - I can't really imagine what knowledge I'd lose.

dcz,
@dcz@fosstodon.org avatar

@deshipu No, but I don't see how formatting it with a linter would make it less possible to understand. Therefore, style doesn't carry any knowledge.

dcz,
@dcz@fosstodon.org avatar

@deshipu The semantics: actual code, comments and variable names. Those are preserved by the linters I know.

dcz,
@dcz@fosstodon.org avatar

@deshipu You can use a tool that removes things that carry knowledge just fine. Just to make it clear, I don't consider comments or names part of style (except whether you use CamelCase or whatever).

But I still don't see what you see: the knowledge thats not in the semantics or naming or comments.

dcz,
@dcz@fosstodon.org avatar

@deshipu I agree with you on variable names. But there's a lot more to linting: spacing, indentation, the placement of brackets. Do you think those carry knowledge?

No linters I know touch names in a meaningful way.

dcz,
@dcz@fosstodon.org avatar

@deshipu If the code has inconsistent indentation, then I let the linter fix it :P

I can see your point: the more sources the author uses, the less likely they are well-integrated, and the more scrutiny they require.

I guess that's a valid point.

In the context of my original complaint, the syntax complaints didn't really lead to more feedback about the content, so I don't think those people were following your observation, really :P Now the question is: what are they trying to achieve.
