i found the titlebar: https://github.com/wezterm/wezterm/issues/6296

it's ugly as hell. but that's partly gnomes fault for not supporting server side decorations. and, at least they are already working on something nicer.

but now i have two sets of titlebar buttons. one set in the titlebar, and a somewhat nicer looking set in the tabbar. but i found a workaround: if i turn window_decorations off, then i get nothing, but i can turn it back on without restarting and then i only get the integrated buttons in the tabbar without the ugly titlebar. now i only need to find a way to script this...

in the meantime i'll just run it without a titlebar. i figured out how to maximize the terminal on startup: https://stackoverflow.com/questions/78738575/how-to-maximize... , that will do for now. i rarely need to resize or close it anyways.

Yeah. This is mostly because of the language syntax scars, and many of them probably will never be fixed. But at the architectural level the request isolation adds a significant robustness. If some request causes crash, infinite loop, chances are the issue is limited to that one request. In NodeJS such issues are much more serious, so coding in NodeJS needs more care and higher qualification.

Here is my opinion on PHP: https://waspdev.com/articles/2025-06-12/my-honest-opinion-ab...

That's fine if the public transport is up to scratch, as well as the cycling infrastructure.

Where I live it's woefully inadequate making driving the only viable option for most journeys.

This has a knock on effect of making cycling down right dangerous in places, because of all the cars + relatively high speed limits, like I wouldn't want to cycle from my house to work, it would be at best unpleasant, and I would be taking my life in my hands on some of the roads.

This was a total game changer for me when running. I would always develop some sort of knee pain at some point but since making a very minor change to how I land my foot, I am running without any.

Make sure to start and transition slowly though as there are warnings about injuring your Achilles and other muscles in your calf if you start off too aggressively.

I live in helsinki and nowhere it is 20 kmh that I know of. Might be some random streets in center. And 30km/h streets are smaller living streets that driving that speed comes almost automatically.

Major ringways and main roads are 80 kmh btw

I have driven in many many countries - Helsinki does not feel slower than any place I have driven, faster in fact because there rarely are traffic jams
by aDyslecticCrow | 2025-08-02 20:34:56+00:00
Most of your commute through a city is turning, accelerating and waiting in traffic. 30km/h or 50km/h makes every little difference in your commute times.

When getting on a larger road with less twists and turns, the speed is higher and the gains of the speed is higher; but the danger is also lower. Any road that may stop to wait for a turn or red light, could probably be capped to 30km/h without much cost to your precious commute time.

i think a large part of this that often goes unstated is the suburban sprawl that causes people to need to drive longer distances near pedestrians to begin with -- do you live in an area with wide streets, many single-family homes, and parking lots? when i've lived in city neighborhoods with dense housing i've only had to drive far/fast to leave, and when i've lived in the middle of nowhere i wasn't at risk of flattening pedestrians

The new huge GM EV & SUV trucks do have way more battery - and weight. The GM Silverado EV Work Truck is EPA 492 miles, tested at 530 by edmonds. So take the common rule of thumb, divide range by half or maybe a little more and you get about 250 miles of towing range. https://news.gm.com/home.detail.html/Pages/topic/us/en/2025/....

In a couple of recent youtube videos, "Aging Wheels" thoroughly tested a variety of trailers towed behind a variety of vehicles and then also added weight to the trailer to see the efficiency impact of towing a trailer with a lot more weight. They found a 4.3% efficiency drop by adding weight to max out the towing, compared to towing without the extra weight. Weight isn't what matters on towing impact, it's the wind resistance of the trailer that matters much more.

They did a long series of comparison drives (in the about 30 mins video) with different trailers and then loaded them with extra weight to see the impact. It was smaller than you expect. The video with all the tests is https://www.youtube.com/watch?v=UmKf8smvGsA.

I heard about this on the batteries included podcast where they interview the author of the video above, and kind of give high level summary with some details, https://www.youtube.com/watch?v=wGJv-xAqcTI.

I've only used the agentic tools a bit, but I've found that they're able to generate code at a velocity that I struggle to keep in my head. The development loop also doesn't require me to interact with the code as much, so I have worse retention of things like which functions are in which file, what helper functions already exist, etc.

It's less that I can't understand, and more that my context on the code is very weak.

>Not half the country, not even a majority of voters.

Not voting was a vote for fascism. It's not up for debate at this point.

>I think a lot of those voted for the racism not the economic collapse.

Um, having grown up in the south I can assure you a lot of these people are full of spite and love to see other people hurt.

They definitely voted for the economic collapse, they're just too stupid to see that it will affect them too.

That's because the Russian alphabet is phonetic (in one direction). So you just need to learn the sounds corresponding to the letters and a handful of rules used to combine them. After that, you can sound out the words aloud, and then it's just a matter of practice.

English is not really phonetic anymore, so this approach doesn't quite work well.

But at the same time, English teachers don't want to go the full Chinese route. Because if learning letter combinations is somehow "colonizing" ( https://time.com/6205084/phonics-science-of-reading-teachers... ), grinding through thousands of words to memorize their pronunciation is probably something like torture and genocide.

I don’t have a source to hand at the moment, but when I looked into the famous Delayed Choice Quantum Erasure experiment the consensus seemed to be:

- The double slit experiment’s conclusions still hold, but:

- The particularly exciting and stark results of the Quantum Erasure experiment may have been misinterpreted or miscommunicated to the public, in particular:

- The presenter of PBS SpaceTime has said that he regrets certain things about how he worded his video on the Quantum Erasure experiment, and I think may have left a comment on the video to that effect.

Every time I look into QM, I keep coming back to the same fundamental axiom: “Quantum Mechanics’ weirdnesses can make otherwise straightforward things frustrating, but will never make interesting inventions possible.” Like how entanglement is able to break locality (which is frustrating) but without breaking causality (which would be interesting). If you hear about a quantum principle and think “Wow, I could use that to build X,” then it’s more likely that you’re not fully understanding the principle (not “you” specifically, I’ve fallen for this myself countless times).

The only exception seems to be Quantum Computing, but even that only arises out of a deep deep mathematical analysis (you can’t get to QC on your own from the things in popular science books) and is only applicable to really niche applications.

I don’t know about major math achievements- the n is pretty small- but homeschooled kids are overrepresented in geography bees, spelling bees, and other academic competitions at the high school level.

https://readlion.com/homeschoolers-dominate-inland-northwest...

It appears that homeschooling enables students to pursue singular passions further than students in schools. It’s not for everyone though.

My point was just to note some other interesting characteristics beyond the age and gender that show up in coverage.

> People who are likely to have crashes are likely to be able who ignore the limit.

... which is why you have to do actual road design. You can't just put up a speed sign and hope people will magically abide by it. Roads need to be designed for the speed you want people to drive. When done properly the vast majority of drivers will follow the speed limit without ever having to look at the signs, because it'll be the speed they will feel comfortable driving.

I do know that because I see the same trucks driving around my neighborhood with Jerry cans and recovery boards 7 days of the week!

Best case you’re looking at 28.5% weekend utilization which isn’t that bad, much better than the 1% I joked with, but how many people do you know taking an offroad adventure every single weekend?

So what? Yeah I don’t really care. It’s mostly hilarious watching them try to park.

It is sort of funny that the one type of software that manages to get any momentum behind it for this sort of thing—games—is really pointless (I enjoy games too, I just don’t think preserving most of them is a big deal).

For work software, it definitely should be able to run locally and without any license server or whatever. I’m baffled by people who don’t feel the need to own their tools. Open Source software mostly seems to fill this gap for me, but like most of the folks here, I only really need programming tools, which are over-represented in the open source ecosystem for obvious reasons.

Proprietary “freehold” software, I dunno. It could be interesting. I guess I kinda feel like: if your software isn’t going to do DRM, talk to license servers, or whatever, I guess your business model must include the fact that people will probably make unauthorized copies of your software. So, maybe just open source it? Then you have the classic “building a business on my open source library” problem, which is very hard, but at least you have lots of company.

Iunno, whatever you can afford?

Nvidia hardware is cheap as chips right now. If you got 2x 3060 12gb cards (or a 24gb 4090), you'd have 24gb of CUDA-accelerated VRAM to play with for inference and finetuning. It should be plenty to fit the smaller SOTA models like GLM-4.5 Air, Qwen3 30b A3B, and Llama Scout, and definitely enough to start layering the giant 100b+ parameter options.

That's what I'd get, at least.

EVs are scam of the century. They have diverted so much economic resources into an end product that isn't even reliable let alone having a long life.

Yet to talk about the amount of mining, its carbon footprint and pretty much irreversible or really high cost extraction/restoration of batteries apart.

Longevity and carbon footprint - If that's not your yardstick than other than that the EVs are great. Have more power than any combustion engine can ever have, have more torque, more acceleration and pretty much zero maintenance as far as the "engine" is concerned. No noise, no emissions, no vibrations either.

Jesus said "sell your possessions, give to the poor and you will have treasure in heaven".

I didn't read the whole article, but it's a great question.

On my religious journey, I have read things like this:

"You cannot serve God and money".

Ultimately, the smartest people, if they are Christian, will actually get rid of their money.

I asked God about it and he told me this:

"There's not enough money for everyone. A truly good person lets everybody else have the money, and just lives on charity".

It shocked me, but Jesus told me this:

"You can get more done without money than with it".

He pointed out the queen of england will never know her true friends, as everybody acts like it.

But if you are poor, you have that knowledge, and can thus live a healthier life.

Ultimately money is based of terror. It is literally based on the terror that if you counterfeit it you go to jail.

So I think that good people would not want to use a medium that requires terror to function.

This may sound crazy, but I think, as a programmer, it is the truth!

But maybe I'm wrong?

So far I've noticed that the actual consulting firms aren't fairing as well. They have to get really lean and focus less on being a body shop and more focused on the high-value delivery -- on what can be very short projects.

I've noticed, however, freelancers do quite well. A lot of this is personality driven. People build good personal brands and they do well, firms want those people and will pay good $$ for them.

Most scooter and bike deaths are from being ran over by a car going too fast for the zone. If you take that into the equation of the car (instead of the scooter or bike); then you probably only have heart attacks from warm weather left as a mortality cause for the bike.

So no, even per mile driven, cars kill people and bikes pretty much don't. And you should take the buss or train everywhere if you follow that logic to the extreme.
by orwin | 2025-08-02 20:40:51+00:00
So, for the records, when epidemiologist say "speed kills", the fact that high speed are more dangerous for your health is not the point.

The main cause of mortal accidents is loss of control, way over attention deficit (depend on the country, in mine its 82% but we have an unhealthy amount of driving under influence, which cause a lot of accident classified under attention deficit. I've seen a figure of 95% in the middle east). The majority of the "loss of control" cases are caused by speed. That's it. Speed make you loose control of your car.

You hit the break at the right moment, but you go to fast and bam, dead. You or sometimes the pedestrian you saw 50 meters ago. But your break distance almost doubled because you were speeding, and now you're a killer.

Or your wife put to much pression in your tires, and you have a bit of rain on the road, which would be OK on this turn at the indicated speed, but you're late, and speeding. Now your eldest daughter got a whiplash so strong they still feel it 20 years after, your second daughter spent 8 month in the coma, and your son luckily only broke his arm. You still missed your plane btw.

I don't know all the answers, but I can tell you that cutting doctors and services is not what I had in mind. Mainly the behemoth that is everything tangential to that, namely insurance and pharma, for two. I worked on the insurance side(in tech), and most people wouldn't believe the number of people involved between the doctor getting money from the patient.

On the contrary of your statement, I would also do everything I could to allow more (capable, of course) people to become doctors each year, though I'm not sure what all that would entail. It feels criminal to me that we limit residency while a) every doctor I've ever visited is way oversubscribed and in a hurry, and b) specialist appointments are months out.

In my experience, Gemini is pretty good in multishotting. So just give it a system prompt, some example user/assistant pairs, and it can produce great results!

And this is its biggest weakness for coding. As soon as it makes a single mistake, it's over. It somehow has learned that during this "conversation" it's having, it should make that mistake over and over again. And then it starts saying things like "Wow, I'm really messing up the diff format!"
by danielbln | 2025-08-02 20:42:03+00:00
Well, yes there is that.

I'd like to say I'm praising the paradigm shift more than anything else (and this is to some degree achievable with smaller, open and sometimes local agentic models), but yes, there are definitely nasty externalities (though burning VC cash is not high up that list for me). I hope some externalities can be be optimized away.

But a fair comment.
by mtrovo | 2025-08-02 20:42:22+00:00
Your example is definitely not a good example of global policies for a local problem. In Wales it was up to the local councils to identify areas that under proper safe circumstances would keep their different limits, defaulting to being reduced to 20mph if nothing was done. That's a very sensible way of handling it.

I have no idea about your stats on driving without a licence being more of a problem than speeding, accidents on roads that got the speed reduced to 20mph or 30mph decreased by 19% YoY, that's a big impact for mostly no additional policing needed.
Show HN: Mathpad – Physical keypad for typing math symbols
by MagneLauritzen | 2025-08-02 20:43:07+00:00
Here's something different than your usual fare: A physical keypad that lets you directly type math!

Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text. It uses Unicode composition, so it works everywhere: Browsers, chat apps, code editors, Word, you name it. Basically, anywhere you can type text, Mathpad lets you type mathematics.

I built Mathpad after getting frustrated with the friction of typing equations in e.g. Word, and what a pain in the ass it was to find the specific symbols I needed. I assumed that a product like Mathpad already existed, but that was not true and I had to build it myself.

It turned out to be pretty useful! Three years of solo development later, I'm launching on Crowd Supply. One of the trickiest parts of this project was finding someone who could manufacture custom keycaps with mathematical symbols. Shoutout to Loic at 3dkeycap.com for making it possible!

Fully open source (hardware + software): https://github.com/Summa-Cogni/Mathpad Campaign: https://www.crowdsupply.com/summa-cogni/mathpad Project log: https://hackaday.io/project/186205-mathpad-the-math-keypad

Not what I meant really. antirez is not a junior yet codes with LLM assistence.

Not sure why this gets downvoted but since when is it illegal to ask whether people actually use intellisense? I mean - what’s wrong with being interests how ppl bootstrap and get to thousands of LOCs in practically no time.

Just for the record - I never said vibecoded.

This guy did tests in a different EV truck https://www.youtube.com/watch?v=UmKf8smvGsA

The results were:

1. Adding weight to the bed, if it doesn't affect aerodynamics, doesn't affect highway range much. For stop-and-go traffic I assume the range would get worse, but he didn't test it.

2. Adding a big air pusher to an otherwise empty trailer murders the range

3. Adding an aerodynamic car or truck on a trailer is better for your range than the air pusher

I do wish it was a hybrid. Maybe small companies don't have the knowledge built up to make a good hybrid drivetrain but hell, Edison is going for it. They're planning to build logging trucks with a diesel generator under the hood as prime mover for a series plug-in hybrid drivetrain. It looks very practical and their initial tests show it tows great. (Since that's their entire selling point, they'd have to fold if it couldn't haul logs)

It is sort of an aquihire:

Mr. Deitke, who recently dropped out of a computer science Ph.D. program at the University of Washington, had moonlighted at a Seattle A.I. lab, the Allen Institute for Artificial Intelligence. There, he led the development of a project called Molmo, an A.I. chatbot that juggles images, sounds and text — the kind of system that Meta is trying to build.

Probably Zuck is trying to prop up his failed Metaverse with "AI". $250 million is nothing compared to what has already been sunk into that Spruce Goose.

Here's a number that should make you vomit: IQ explains about 21% of income variation. That's it. Four fifths of why someone makes bank has nothing to do with their brain. Nobel economist James Heckman ran the numbers harder and found IQ accounts for 1-2% of income variance when you factor in everything else. One to two percent. Your SAT score is basically a rounding error on your paycheck.

he's ignoring individual preferences. In the context of a career setting, making a lot of money is conditional on passing the screening and interviews, which are indirectly IQ filters. So people who are smart and whose preferences are aligned towards wealth accumulation are at an advantage. You don't get into Jane Street unless you're smart.

No, it doesn't. Those low speed limits are only used for smaller residential streets. It only impacts the part of your journey from your home to the edge of your neighbourhood, and the same at your destination. Regardless of journey distance, the vast majority of your trip will be spend driving on roads intended for through traffic - which will of course still have a higher speed limit.

Percentage-wise it is only going to meaningfully impact your travel time if you stay within your own neighbourhood. At which point the only logical response can be: why are you even taking the car?
