As someone who's put an embarrassing number of hours into Stardew Valley, this all really resonates. Cozy games give you this weirdly powerful illusion of control and calm - your farm, your pace, your little pixelated life that somehow feels safer than the real one. It's not just escapism - it's like a reset button for your brain. I love that the article highlights how these games aren't necessarily "easy," just low-stress. They let you engage deeply without the constant threat-response loop that most traditional games (or life) tend to trigger.

Batteries are cheap. Installing lots of copper lines for trolley buses isn't. That's why trolley buses are pretty rare. Old idea, didn't really take that well. There are a handful of cities that have them. And they've had them for decades. Most of those cities now also have battery electrical buses to service all the areas where the cables don't go. Expanding the network of cables doesn't seem to have a very high priority. Installing chargers (in depots mostly) is much easier and cheaper. And it's not like batteries are that expensive.

With battery prices trending to 50$ per kwh, a decent size bus battery of 250kwh would cost about 12.5K. That's manufacturing cost, not purchase cost. But it drives the point home: long term batteries are going to dip even further. Far below 50$/kwh. It will drive down the cost of battery electric drive trains for everything with wheels to far below that of the traditional setup with ICE engines. And they don't need expensive fuel to run. Or a lot of engine maintenance and servicing.

Currently tens of thousands of electrical buses are produced per year. Most of them in China. Which is of course where they have lots of battery factories. It's a rapidly growing industry.

Confirmed crimes are not allegations. He entered the USA illegally - without "due process". He is a member of a foreign terrorist organization. He was even arrested in the company of MS-13 gang members with long criminal records.

If you are talking about rule of law and "due process", you must honestly bow and congratulate the now effective immigration law-enforcement. Finally "due process" is being followed, after 4 years of being asleep at the wheel, not enforcing federal law, deliberately breaking formal oaths of service and mockingly lying to Congress under oath.

Elizabeth Kessler - the immigration judge declared in charge of his case declared that this man's release in the USA would endanger the public since "evidence shows that he is a verified member of MS-13.". Hell, even an appeals court later affirmed the judge's decision.

A violent gang member was deported to his nation of origin following the ruling made by an immigration judge and even subsequent appeal. The executive branch of the US government then performed according to mandate and deported him accordingly.

Due process was followed.

Its not complicated.

> I'd bet over 50% of the things that you think happened

How and why would that change anything in any way? From a rational perspective 5% of those things are way too much already. Much less even...

In a rational and sane world Trump would have been impeached and possibly imprisoned just over his government funded golf trips that he is using to funnel millions of tax payer money to his own businesses. Just running a car dealership on the white house lawn should have resulted in impeachment. Yet these are the tiniest most insignificant things compared to everything else he is doing.

In our unfortunate reality paying him several hundred millions to just do nothing but play golf for 4 years would seem like an exceptionally good deal..

I mean your argument is basically “well he’s extremely horrible but at least he doesn’t eat babies, so shut up..”

Wasn't there a recent recall of 4a phones that had their battery life killed by an update? My friend could barely keep his on for an hour.

My Pixel 5 also turned into a broken mess in its last year. It was as if I had a completely different phone. I was hoping to keep it for at least two more years but the battery became really bad and the OS became super buggy.

Sometimes it's not about the straw but about the camel's neck, you know, the one thing that was too much. Sometimes the crowd's the one who decides about the next song on the playlist, not the DJ, and it could have been literally any old song.

Do you remember writing the proof for quicksort, which is say 0.1k lines? 15k lines of verified code is a pretty good indication of effort.

But the problem may come from the headline, which is somewhat clickbaity. HN forbids changing it, and then part of the discussion focuses on the literal content of the headline, which is, as you rightly hint, not the best summary of what's interesting here.

Some further context for anyone who reads this and thinks it's a factual or plausible summation of the factors that influence HN moderation:

- Gumroad is not a YC-funded company and its founder has no influence on YC or HN.

- Joe Gebbia is just one of more than ten thousand YC-backed founders and does not represent YC or influence HN.

- Of the other people named, none has any official role or influence at YC, and only one of them has ever had a formal role; a brief, minor role that ended over seven years ago. At least two of those named have had very public, bitterly hostile disputes with former presidents of YC and founders of notable YC companies.

- The only person with any role/influence at YC who publicly espouses any position on U.S. federal politics is Paul Graham, who tweets almost daily in staunch opposition to the current U.S. administration.

- HN moderators and YC management know that HN is only valuable if it is a place where people can find content and discussions that engage intellectual curiosity, and the surest way to destroy its value is to allow it to be captured by any political or ideological agenda.

On one hand I'm tempted to say: "yes of course". On the other hand I feel like saying: even a slight amount of accuracy would be very out of place for claims involving Tesla, wouldn't it?

> In the airline industry they have checklists

Yes, and The Checklist Manifesto (which is a fantastic book) was published in 2009; yet it seems little progress has been made since.

It's not just checklists, though, it's also basic CRM. If the lead surgeon is God, and you're a nurse, you don't speak up -- you probably don't even believe your own senses when they tell you something's wrong.

A fundamental change is sorely needed -- not sure what will make it happen.

It does feel a bit similar to sitting down with a good book and taking things ahead at your own pace, quite zen.

I will say that personally even the more action/goal oriented games can be quite enjoyable as long as they’re not too difficult, it’s the online PvP ones that get the most stressful for me. I don't really play many of those anymore, it feels like other players are just better and I don't want to have to be on the edge all the time.

Oh also it’s a really nice site!

This math is for future busses designed for city use - so batteries will be much smaller and therefore lighter, and the bus construction itself will be much lighter because, as you point out, with a city bus pulling away ~5 million times in its lifespan, the cost of energy lost when stopping and pulling away far exceeds the cost of upgrading the frame to aluminium and other weight saving measures.
Show HN: Undercutf1 – F1 Live Timing TUI with Driver Tracker, Variable Delay
by deltaknight | 2025-04-19 07:50:36+00:00
undercutf1 is a F1 live timing app, built as a TUI. It contains traditional timing pages like a Driver Tracker, Timing Tower, Race Control, along with some more detailed analysis like lap and gap history, so that you can see strategies unfolding.

I started to build undercutf1 almost two years ago, after becoming increasingly frustrated with the TV direction and lack of detailed information coming out of the live feed. Overtakes were often missed and strategies were often ill-explained or missed. I discovered that F1 live timing data is available over a simple SignalR stream, so I set out building an app that would let me see all the information I could dream of. Now undercutf1 serves as the perfect companion (like a second Martin Brundle) when I'm watching the sessions live.

If you want to test it out, you replay the Suzuka race easily by downloading the timing data, then starting a simulated session:

1. Download undercutf1 using the installation instructions in the README.

2. Import the Suzuka race session data using `undercutf1 import 2025 -m 1256 -s 10006`.

3. Start the app (`undercutf1`) then press S (Session) then F (Simulated Session), then select Suzuka then Race using the arrow keys, then press Enter.

4. Use arrow keys to navigate between the timing pages, and use N / Shift+N to fast-forward through the session.

If you want to test it out during this weekends Jeddah GP, simply install as in the README then start a live session by pressing S (Session) then L (Live Session).

The app is built for a terminal of roughly 110x30 cells, which probably seems an odd size but just so happens to be the size of a fullscreen terminal on a MBP zoomed in far enough that the text is easily glanceable when the laptop is placed on a coffee table some distance away from me :) Other terminal sizes will work fine, but information density/scaling may not be ideal.

If you're using the TUI during a live session, you'll want to synchronise the delay of the timing feed to your TV feed. Use the N/M keys to increase/decrease the delay. During non-race session, I find it fairly easy to sync the session clock on TV with the session clock on the bottom left of the timing screen. For race sessions, synchronisation is a little harder. I usually aim to sync the start of the race time (e.g. 13:00 on the timing screen clock) with the start of the formation lap, where the live feed helpfully shows the clock tick over to 0 minutes. I usually delay the feed by 30 to 60 seconds.

It's good to be aware of the likelihood of astroturfing. Everytime there's a newthread like this for one of the companies, there's a suspicious amount of similar plausible praise in an otherwise (sometimes brutally) skeptical forum.

The best way to shift or create consensus is to make everyone think everyone else's opinion has already shifted, and that consensus is already there. Emperor's new clothes etc..

I've upstreamed patches too and I increasingly feel like it's a waste of time and that it requires far more effort than it's worth. Good maintainers who work with you are rare. I remember the ones who do.

> Nobody ever said no to genuine high quality bug reports that were coupled with good fixes.

Uhuh.

> ask how receptive they are

Doesn't really help much. It's entirely possible for people to tell you it's fine then change their minds after you actually do it and send the code in. Seriously hope you never have to experience anything of the sort.

I’m not sure I understand this argument. Anything that runs in a lambda can also be run outside of a lambda. You just need to give yourself a way to invoke it or access it.

One setup I’ve used with a previous client was deploying many FastAPI lambdas, wrapped in Mangum. You can even in the same code base expose both. This way, you can deploy to a container and a lambda without changing any code.

In one case, we used APIGWv2 to give the lambda an HTTP endpoint, in the other, it’s the container that provides it. You can throw in IPv6 support by having a CF distro in front of both.

Yeah, I like gathering/crafting mechanics but it has to be a focused experience, either I'm out on an adventure and happen to pick up some useful things on the way, or the whole point of the adventure is to pick up one or more things I need. Either way, the movement still has to be slick enough to not be boring, and the world has to be engaging enough to warrant caring about moving through it.

There absolutely exist checklists for safe surgery as well, most famously the WHO Surgical Safety Checklist [pdf]: https://iris.who.int/bitstream/handle/10665/44186/9789241598...

It's definitely widely used in Germany, where I work. I don't know how common it is in the US, though.

I often think about what makes medicine so different from aviation and your other examples, culture-wise. It's not like there's no safety culture at all in medicine, but clearly these kinds of structures are deployed to a much lower extent.

One major reason might be the far larger diversity of possible situations in medicine. It's possible to make a checklist for surgical safety because every surgery is similar, same to how every plane flight is similar. But if I think about, for example, harm due to adverse effects from medications, or missed abnormal values in blood tests, it feels very difficult to create a checklist to prevent those that would be specific enough to be useful, but also general enough to capture all important situations these might arise in.

In this sense, I think certain “low-hanging fruit” of safety culture improvements have already been captured in medicine. Apart from surgical safety, I can think of check lists for chemotherapy administration, for blood transfusions, for management of a severe allergic reaction, and other specific individual things. Pointing and vocalizing is also done in surgery, albeit in a less formal way. “Two sets of eyes” policies exist in e.g. pathology for more certainty in diagnosis of cancer.

Nevertheless there is clearly room to improve, as evidenced by the continuing occurrence of “never events” such as retained foreign bodies in surgery. There are certainly economic factors at play here as well: unlike in the free market, in the medical system there is often very little economic incentive for quality, and the same principle I mentioned before — of the immense diversity of possible situations — makes top-down regulation very tricky.

Maybe part of it is also that the potential harm from a retained foreign body is much lower than the potential harm from a plane crash. And maybe medical care is so much more common than plane flights that by base rate alone, mistakes in the former will be much more common. Yet I still think there is much that can be done, and I am unsure what exactly is preventing that from happening.

Actually all the vehicles you mention are already available in battery electric form and typically already far more common than their hydrogen equivalents. Everything from mining trucks to scooters. Batteries are cheaper than fuel cells. And electricity is cheaper than hydrogen. You are right that there's a lot of potential for further cost reductions with battery electric through innovation and numerous paths for doing so.

With hydrogen there simply isn't any obvious path forward. Hydrolyzers are inching closer to their theoretical maximum efficiency. Same for fuel cells. A few percent improvements here a few percent there. End to end battery electric wastes far less electricity. So it's inherently cheaper to charge a battery than it is to fuel a hydrogen vehicle. This is a gap that cannot be bridged.

With batteries we're looking at steep increases in energy density by multiple factors, new chemistries based on commonly available materials, cost reductions, etc. They are already competitive now. But it's going to get far worse for hydrogen very quickly.

Simply put, hydrogen is dead as a door nail for anything with wheels. There's a lot of subsidized inertia in the market. But without subsidized hydrogen, there is no business case to use hydrogen. None whatsoever.

> Hydrogen is a quicker refuel

Only slightly. It's not that fast actually. The naive notion that you just slosh some hydrogen in a tank like you would with diesel is not based in reality. Pumping compressed gas through narrow hoses takes time and hydrogen has a lot of volume. 10-15 minutes to refuel a truck is pretty normal. Charging can take a bit longer; depending on the size of the charger. And there is a path to making that quite a bit faster.

Agreed. I used to race on a one design 34ft boats (steward 34s for the kiwis here). For the Thursday night rum racing they always casually divided up sailors amongst all the available boats and therefore the yacht squadron would refer people in town to them. So naturally we got a lot of cruisers on there around the world trips who wanted to try out racing. The most striking was the lack of urgency. Even though many were quite experienced sailors they were often worse than people who never sailed before. The newbies could be told to which as if your life depends on it and they would go full out, some of the cruisers not so much.

I haven’t seen those theories before. The first one seems intuitively apt.

If you are overwhelmed the first thing that goes is your leisure and creativity. Say if you used to play piano or did any hobby, and you stopped, it means you lacking bandwidth to relax. After that, and you don’t correct your brain starts changing until it breaks : a burn out, or even further along : PTSD.

So to counter it, is to bring back leisure and your hobbies.

If someone burns out right next to you (I have had that happen to a colleague) is a couple of things : you can ask them if possible to focus on deep breaths, or ask them to call out the name of objects and ask them to describe them. Another strategy is deprive them of sensory overload. Have them put the hands on their face and hunch over so they are in their own cocoon. Stay with them and soothe them until you get a professional over.

I am not sure if this is the most current view, but this is from my direct experience.

>That's because I've had to conclude two things: First, the Russian economy is even more opaque to western analysts than the analysts already admit it is.

Or it's not all that opaque and you've been reading tons of propaganda disguised as economic analysis in order to manufacture support for the war in the West. "Just 50 billions more for Ukraine and it's going to win."

YouTube's algorithm has created over the last ~5 years an entire cottage industry of click-maximizing content creators who take any interesting scientific discovery or concept, turn it into the maximally hypey claim they can, and make that the title of their videos with a "shocked-face" thumbnail.

E.g. imagine an arxiv paper from French engineer sebastiennight:

Using quantum chips to mitigate halting issues on LLM loops

It would result the same day in a YT video like this:

Filters. If you can come up with a problem where incorrect solutions can be filtered out, and you accept that LLM outputs are closer to a correct answer than a random string then LLM's are a way to get to a correct answer faster than previously possible for a whole class of problems we previously didn't have answer generators for.

And that's just the theory, in practice the LLM's are orders of magnitude closer to generating correct answers than anything we previously had.

And then there's the meta aspect of them: they can also act as filters themselves. What is possible if you can come with filters for almost any problem a human can filter for, even if that filter has a chance of being incorrect? The possibilities are impossible to tell, but to me very exciting/worrying. LLM's really have expanded the realm of what it is possible to do with a computer. And in a much more useful domain than fintech.

Yes, there is no state and state transition matrix, really.

Kalman filters are good where you have a system with a state, and an estimate of the state, and you act on the system, and then you measure the outcome, repeatedly.

Acting on the system and propagating your estimate forward "one step" increases the uncertainty of your estimate, and measuring decreases the uncertainty of your estimate.

There's a similar danger with very quiet and/or electric cars where people near the school barely hear them coming and need more attention to keep themselves safe. Avoiding an older gas or diesel car is practically automatic as you can hear their speed, acceleration and location comparatively far away. I think EV manufacturers have added some sort of noise to low speed driving, but I haven't heard anything beyond one being right behind me

This is very interesting! I enjoy playing Gran Turismo 7 and often find it very calming; especially when I'm in a flow state and can get through a tricky part of the track very quickly without any mistakes.

I wonder if this is a case where both theories apply - the rhythmic, controlled driving stimulates the 'soothing system' while the challenge of maintaining control at high speeds provides that 'risky play' element.

> To do so, we must solve (1+r2)^12 = (1+r), which requires logarithms

No, it doesn't. r_2 = (1 + r)^{1/12} - 1. Compound interest looks like (money) = (money_0)*r^t; you'd only need logarithms if you were trying to solve for time.

> Now, it might be natural to ask what about for continuous compounding?

I can't tell what you're getting at here. Once you've written down the equation (1 + r_2)^{12} = (1 + r), you've already provided a complete solution for continuous compounding. If the time you want to compound over is t, and Y is one year, then the solution is always given by (1 + r_2) = (1 + r)^{t/Y}. Nothing goes to infinity.

You can put effort into all that, observe all the best practices, follow all the rules, try your very best and still end up with literally nothing to show for it simply because the other guy doesn't want to.

vi and the UNIX shell are just beautiful tools.

It always amaze me that I was only introduced to them in my adult life way after Windows, but still for me they are the definition of what computer is.

So this is not really about (personal) nostalgia.

Also in the age of 8K screens, VR, AI and AI ready computers, a lot of people still use and love vi.

Call me crazy but my guess is there might still be vi users in 50 years.
