cycomanic··on The American Healthcare Conundrum
This reminds of a debate in the German parliament 30 years back or so, about the cost for the Eurofighter project (IIRC). Essentially one speaker had argued against the staggering cost, and a second speaker from the government defended the project by saying how many jobs it created. Someone shouted that building a pyramid in honor of Helmut Kohl and it would create a lot of jobs as well, that didn't mean it's a good idea.
cycomanic··on Gitana 18: the new flying Ultim trimaran
Have you watched sail gp or the recent America's cups. The racing is as incredibly exciting to watch and the skills of the sailors is a huge part of it. I'd argue that technology was always a huge part of sailing, but compare that to many of the "old" America's cups and now you'll see the racing is so much more exciting (largely because while technology is at the forefront, the rules make boats technologically advanced, but also comparable enough to each other).

I'd also argue that sailors (and particularly skippers) are still celebrities (within the sailing community). Now where you're right, is that that these boats are not accessible to the average sailors anymore, but it is because they require so much skill to sail.

cycomanic··on Hollywood Enters Oscars Weekend in Existential Crisis
Well at least it's not Amazon prime where they now interrupt the movie for the same ad/trailer 3 for weeks unless you pay extra again.

Fwiw I always enjoyed the trailers at the movies, no the other ads I could very much do away with (and I used to purposefully come late to shows to miss the ads).

cycomanic··on Python: The Optimization Ladder
What is the point of your post? I find it increasingly tedious to read comments about alledged AI use under almost every post. It's like complaining that you didn't want to read the submission because you didn't like their font or website design.

I think almost everyone here agrees they don't want to read AI slop, but this submission clearly wasn't that as you admit yourself.

cycomanic··on Sub-$200 Lidar could reshuffle auto sensor economics
> According to that article, Waymo crashes 2.3x more often than human drivers (every 98k miles vs 229k miles), which is clearly false.

Why is it clearly false? It might be false, but clearly? I would definitely like to see evidence either way.

> I think it's far more likely that humans don't report most minor collisions to insurance, and that both Robotaxis and Waymo are safer than human drivers on average.

That sounds like you are trying to find reasons to get the conclusion you want.

cycomanic··on The dank case for scrolling window managers
I can just give you my view. I've been a TWM user for >10 years than switched to niri via some of the sway/hype land scrolling plugins.

My problem with TWMs was always that depending on monitor size you can open 3-4 windows in a set layout (be it the tradional spirals, or H splits...) before you have to do "manual" window management (i.e. move windows into tabbed layouts, move them to new workspaces,...). So for me that generated a friction, where sometimes I just wanted e.g. to quickly open a terminal do some things but keep the rest the same, but not knowing if the terminal becomes permanent. I other words in TWMs I found myself having to know what exactly I want the window for all the time.

SWMs get rid of that friction, I just open a new window and it gets pushed to the right, while keeping windows at the perfect size and if not I can easily switch between the 3 sizes I want (never found I needed more than fullscreen half screen, third of the screen). So I simply don't have to think what I want the e.g. terminal for (something long term or just quick try) before I use it. While it sometimes makes finding the right window a little more messy (the overview really helps though), I find I end up more organised, because I keep related windows in the same workspace, while on TWMs I ended up with 3 or 4 workspaces just for temporary terminals (which made finding the right one often very messy as well).

cycomanic··on People who know the formula for WD-40
That's not really true. There's lots of research out there showing that waxed chains result in less power loss over longer time compared to no lubrication and most other lubricants (both bicycle specific ones and more general ones). Now waxing your chain is admittedly annoying, but it does work.
cycomanic··on US Places Arctic Airborne Troops on Standby as Greenland Dispute Escalates
Your link actually proves the OP right and you wrong. Look at the graph of the running average of GDP and you see that after a huge spike in the 40s (due to the WW2 effort) GDP growth settles on a new higher average (with significantly less fluctuation).
cycomanic··on If you put Apple icons in reverse it looks like someone getting good at design
Why are people arguing that icons should be intuitively tell you what the app is about? Since when was that the goal of an icon (in paritucal an app icon)? It should be easily distinguishable from other icons. If I don't know what the icon means it will take me exactly 1s to find out by clicking on it, after that I will know what the app icon is for, and I only care if I can distinguish it easily from other icons, so I don't accidentally start a different app.
cycomanic··on On Being a Human Being in the Time of Collapse (2022) [pdf]
This is one thing that I don't understand, take for example Germany, the population barely grew over the last 20 years [1], at the same time there has been a building boom that building costs have risen dramatically (more than doubled between 2010 and 2024). Compare that to the 60s and 70s where population was rising much faster in combination with the rebuilding effort. So is the growth of housing stock lower than the population growth? If yes how come that this was not the case when population growth was significantly faster (even 30 years ago). I don't recall there being more building going on when I was young than now, in fact if anything my impression is it's the other way around.

cycomanic··on Why some clothes shrink in the wash and how to unshrink them
Yes completely agree. I always hang up my washing (also in NZ, don't have a dryer) and was recently sorting through my tshirts as we are moving country. I have one t-shirt that is nearly 20 years old and still holds its shape (though the color and print has faded) on the other hand i threw away a bunch of other t shirts which were just over a year old because they developed holes and particularly the collar is completely broken. Funnily their color and print is mostly fine.

I don't think brand is a good predictor either, e.g. the old t shirt is from threadless IIRC while I had many other threadless tshirts which didn't last near as long.

cycomanic··on Statement from Jerome Powell
You're joking right? People got arrested and jailed for posting a Kirk meme https://edition.cnn.com/2025/12/17/politics/retired-cop-jail...

Let's not even talk about all the other rhetoric of arresting and even killing people who voiced different opinions coming from the current regime.

cycomanic··on Meta announces nuclear energy projects
Not sure I understand your point. In the plot you mention what the OP said certainly holds true for China and Europe (less so for the US). Also the Charts plot investments not just new capacity investments, I'm not even sure how you distinguish between the two?
cycomanic··on Meta announces nuclear energy projects
Even China who committed to significant nuclear capacity and wanted to ramp up their nuclear percentage to 20% (IIRC) is slowly moving away. The percentage of nuclear has in fact reduced over the last 5 years and initial commitments/projections of nuclear capacity are likely not going to be med. The whole reason being that solar (and to a lesser degree wind) have become so cheap that nuclear just doesn't make economical sense even for China.

And that is different from more hierarical organisations how? I mean there are plenty of stories about infiting, thiefdoms, manuvering... in hierarical organisations as well. There's also lots of example we're the disconnect between the top and lower tiers of the hierarchy (i.e. the essence of the hierarchy itself) let to the downfall of the organisation. I also fail to see the connection to the article, the organisation did not seem to have failed (in the view of the author at least), due to the failed "democratic" organisation experiments, but due to the leadership in the current hierarical organisation not listening to the "lower tiers". So if anything it seems to be a problem of the hierarical structure.

> Humans are complicated, and we do seem to have a certain amount of low-level social wiring for hierarchy and pecking order, even if it's far from absolute. >

I dislike these generalised statements about "human nature", there is way too much uncertainty and plenty of counter examples.

That said I agree with some of the other points you made, the post reads a bit weird considering that the author essentially gave up his ability to influence the course of the organisation (both by giving up his leadership seat, but also before by disenganging from the process), and the complains that the organisation did not develop how they wanted.

I don't think it is, the aspect ratio seems off, but maybe I'm misremembering (not in Germany right now)
cycomanic··on Murder-suicide case shows OpenAI selectively hides data after users die
I think the difference between sycophancy and NVC (at least how I learned it) is that a sycophantic person just uncritically agrees with you, but NVC is about how to communicate disagreement, so the other person actually listen to your argument instead of adopting a reflexive defense response.

Maybe that was necessary to get it passed their CEO...?
cycomanic··on Python numbers every programmer should know
But these performance numbers are meaningless without some sort of standard comparison case. So if you measure that e.g. some string operation takes 100ns, how do you compare against the numbers given here? Any difference could be due to PC, python version or your implementation. So you have to do proper benchmarking anyway.
cycomanic··on I rebooted my social life
That's interesting, but in my experience cycling groups are the most social individual sports groups (even more social than many team sports even). Even the performance focused groups tend to stop at the coffee shop for some banter after the ride, and some less performance oriented groups seem to be more focused on the coffee than even the ride itself.

Are you talking about road cycling or mountain biking? My experience is definitely with the former. I think it helps that in group rides you automatically end up riding next to someone new and chatting along. Easily breaks the ice.

cycomanic··on I rebooted my social life
I can only speak to my own experience, but for the last 1 year I have been by myself and my 2 younger daughters in a new town. I work remotely, but also have some very good friends that I can rely on when I need. Those friends are distributed all over the world and while I can call them any time off the day or night, there is a fundamental difference how I feel after a phone/video call to after a conversation over e.g. drinks/dinner. In fact I found that I sometimes avoid calling my friends because the phone call makes me feel lonelier.

So for me online communities can be a great thing, but they can't replace IRL communities, because the interactions make you feel different. I suspect that the social needs that evolution has imprinted on us can't just be fulfilled by online interactions, they require more senses than just hearing and seeing.

cycomanic··on What an unprocessed photo looks like
That comment does not make sense. Do you mean the sun emits it's peak intensity at green (I don't believe that is true either, but at least it would make a physically sensical statement). To clarify why the statement does not make sense, the energy of light is directly proportional to its frequency so saying that green is the highest energy light the sun emits is saying the sun does not emit any light at frequency higher than green, i.e. no blue light no UV... That's obviously not true.
cycomanic··on Apple releases open-source model that instantly turns 2D photos into 3D views
> Not sure I've met one of those people in... a decade or so? Loving apple products has been an uphill road for a long time (and increasingly more so post-Jobs)

You either a deliberately misrepresenting the facts or been livoning under a rock. I mean read any discussion about M laptops and you see apple fanboys noncritucally declaring them a revolution in computing.

cycomanic··on Apple releases open-source model that instantly turns 2D photos into 3D views
This bugs the hell out of me, somehow these companies argue that training on all sort of content without is fine because reasons and then have the audacity to attach a new proprietary licence to it.
cycomanic··on Researchers develop a camera that can focus on different distances at once
I doubt resolution is a limiting factor LCoS (transmissive ones are lower resolution typically though, but you could build reflective) phase modulators are available in 4k resolution (and maybe even higher). And I don't know if you need that much resolution because the regions you're trying to focus are quite broad, in fact I suspect the resolution of your phase modulator would not limit resolution but the max distance between focused regions, because it would set the max phase ramp you can achieve.

Loss, i.e. equivalent aperture is a different matter and I think this would imply quite a light loss.

cycomanic··on Splice a Fibre
I did my PhD on fibre lasers, 0.1 DB would have been considered a ver bad splice and I would have recut and respliced (if you have 1-10W in your cavity that 0.1 dB loss would risk burning and the fuse propagating through your cavity destroying everything in its path (as a side not look up Videos of fibre fuse, looks fascinating). In my experience 0.01-0.02 is much more typical than 0.1 dB loss.
cycomanic··on Rob Pike goes nuclear over GenAI
I would argue that Google actually has had a comparitively good track record on the environment, I mean if you say (pre AI) Google does have a bad track record on the environment, then I wonder which ones do in your opinion. And while we can argue about the societal cost/benefit of other Google services and their use of ads to finance them, I would say there were very different to e.g Facebook with a documented effort to make their feed more addictive
cycomanic··on Phoenix: A modern X server written from scratch in Zig
> I didn't think my explanation implied how you interpreted it. > > I thought everybody knew Wayland was started by some people working on Xorg already; I did not mean to imply otherwise. Many or all were paid for their work. They believed Wayland was a better approach, and, AFAIK, at some point switched to be paid full-time to work on Wayland instead of X. Which, sounds a lot like they convinced their employer (or a new employer) to pay them to work on Wayland instead of X. Do you believe this is a fair summary of the situation?

Sorry for my combatitive before. I definitely interpreted your previous post differently and I think your clarification is a fairer assessment of the situation. I would still argue that the majority of people implementing the wayland protocol are not paid by their employers to do so (this might now have changed a bit with smithay, which is sponsored by system76 I believe).

cycomanic··on Who Watches the Waymos? I do [video]
Not sure if it's sold in the US (assuming you are from there), but the Kia PV5 is probably your best bet. On top of that it's very reasonably priced (in contrast to the ID buzz)
cycomanic··on Phoenix: A modern X server written from scratch in Zig
So what is it, in one comment you say there were plenty of x11 devs who objected to wayland (please name and show the posts) and on the other hand you say there were not enough to keep an xorg fork going?

People are arguing that fixing the issues in X11 would have been much easier and less work than making wayland. So why could those half of x11 developers who left make wayland while the other half that was left over could not even make one release?
