To be fair, I did couch my post right in the first sentence. I wasn’t faulting other devs with it though, not keeping an anti-cheat team or if one exists, not keeping it flush with top notch talent and resources would be the fault of management and the suits at the top, not that of ICs in the trenches like devs.

Maybe I’m misunderstanding, but ECMWF provides a lot of data and forecasts for free [1]. And they are increasing the amount of data that is free [2].

I had a MacBook once that lasted for 13 years, and that's what I used to assume people meant by "crazy good lifespan".

Once on this site I saw someone talking about how the lifespan is so good they only had to replace their MacBook every two years instead of every year, and it just made me realize "crazy good lifespan" is meaningless.

>The same electrical potential may still be present in the clouds

I wouldn't jump to this lemma so quickly. The paper mentions the density of aerosols. Sulfur oxides promote condensation by forming low-volatility compounds like H2SO3 and H2SO4. An increase in the number density of droplets could mean more triboelectric charge transfer between the droplets and the air. That would increase the amount of electric energy in the clouds.

This is also the mechanism by which sulfur has been proposed for geoengineering, but I think the variant that replaces sulfur with terpenes sounds safer.

Tennis requires a certain proficiency to have fun with. Beginners tend to have trouble getting the ball reliably across the net onto the other player. This proficiency takes time to build. Thus, unless one makes a big up-front time investment, tennis is not particularly good exercise. Up-front time investments are expensive.

Also one cannot tennis alone. Anything one must practise with a partner is more expensive due to scheduling requirements.

I spent the last half of the 90's and the first part of the early 2000's building computers. Like the author, it started with a massively thick Computer Shopper catalog. Motherboard from TC Computers, 1.3GB Dirt Cheap Drives, 16MB of 72pin DIMMs from my dad's old Compaq. 486DX4 from some other seller. Man that was such a rush cobbling that thing together. But the bug stuck with me and eventually got me a job - which got me installing Novel, WindowsNT and eventually Linux! Then my boss sprang the big one on me, "you know, the real money is in software development". What a great trip down memory lane.

Intel failed because the Taiwan government started tsmc and supported an amazing business model that turned out to be perfect for SC manufacturing.

Unfortunately, this is in a country that China is threatening to takeover while building the largest bomb shelters and field hospitals right across the strait.

China is forcing us to invest kind of like they are forced to prop up Huawei to make GPUs for deepseek. Conflict makes irrational actions happen.

It takes some sifting to find some really good “making” channels on YT. I’ve watched this video and while I applaud author’s efforts, I don’t consider this type of content “good enough” to be subscribing. It felt overproduced and with too epic tone, while giving too little detail on the process, the experimentation, the actual solution (he said ratios are important, but what ratios did he use) and no thorough explanation of what is happening.

The golden standard is Applied Science channel, of course, but there are some smaller channels with similar vibe.

Your insurance is almost certainly a factor here, in that they require you to see a GP before escalating the issue to a specialist (one of the most highly-paid, I might add, who might have a busy schedule also). But what you've described is not uncommon for any insurance company.

Other countries with "universal healthcare" also have times consuming referral processes and wait lists for stuff. But they have it worse because there are more people seeking service, and less providing it (because profits are capped). I've heard plenty of stories of people in those countries dying on the wait lists for things that sound urgent or mundane, like appendectomy surgery. I even heard a few where people with ordinary problems like trouble walking were offered euthanasia. You should do a bit of research before you whine too much.

So, what would solve the problem of having to wait? Ultimately more supply of service providers, less demand, or an unlimited budget to pay for the scarce ones that exist.

> Do people actually use GitHub copilot?

I use it all the time. I am not into claude code style agentic coding. More of the "change the relevant lines and let me review" type.

I work in web dev, with vs code I can easily select a line of code that's wrong which I know how to fix but honestly tired to type, press Ctrl+I and tell it to fix. I know the fix, I can easily review it.

Gpt 4.1 agent mode is unlimited in the pro tier. It's half the cost of claude, gemini, and chatgpt. The vs code integration alone is worth it.

Now that is not the kind of AI does everything coding these companies are marketing and want you to do, I treat it like an assistant almost. For me it's perfect.

The point is corporate wouldn’t need to replace the Apple MacBooks after 3 years. I’ve got an M1 air bought what feels forever ago and it’s still as fast as I need it to be. I’ve also been using hp laptops in my previous job and they couldn’t even wake from sleep when needed (but would wake in backpacks to the point IT explicitly forbade putting sleeping laptops in bags. Absurd.)

Job's vision was seeing that hardware and software vertically integrated had a strong position in the market, despite being told to sell off the hardware division and focus on OS work. His vision was to never give out dividends or buy back stock: always plough the money right back into the company.

Musk has the unbound optimism of his ability to succeed. He's good at selling that optimism to others. His decision making is often heavily seated by public opinion and the market.

Also the whole fascism thing.

Of the two Jobs actually accomplished what he sets out to do. Musk's batting record is more spotty. He's got some wins (Falcon 9) but boy howdy does he have a lot of losses, and he's just gearing up to take increasingly more L's

> Why would you care about these kinds of micro-optimizations

it turns out that compiler speed is bound by a bunch of things, and it's death by a thousand cuts. If you have a slow compiler, and it takes forever to compile your compiler, your language becomes scelerotic, no one wants to make changes, and your language gets stuck in shitty choices.

> Because a compiler is not some simple CLI tool with a fixed upper bound on resource consumption

yes. thats right. a compiler is complex and should use several different allocation strategies for different parts. if your language steers you towards using malloc for everything then your compiler (assuming it's bootstrapped) will suffer, because sometimes there are better choices than malloc.

The only meaningful difference between my ThinkPad's trackpad and the one in my work Mac is that the Mac has a bigger one. I don't really get why some people seem to be under the impression that Windows laptops come with trackpads from the twenty years ago.

The CPU architecture is great and I hope Qualcomm will soon be able to replicate it in normal laptops. I don't think desktop users care about that as much, though, and macOS has just as many infuriating particularities as any desktop Linux OS. It just comes with better drivers.

> It wasn’t just harder or more expensive. It seemed like every new build was an adventure.

Not sure how it was in the 90's, if it was harder it was probably because the case designs were much worse, but I think PC building is not at its easiest today either and was probably easier in the mid 2000s or 2010's (but, of course, it's still fun!):

- Graphics cards and CPUs are more power hungry, e.g. there's more fire risk from GPU power connectors now

- Graphics cards are also heavier so physical strain and location/orientation matter, some even come with a "card holder" (a little pillar to support its weight)

- There now exists "RAM training" (which can make the first bootup look as if it's failing) and in general compatibility between RAM's max speed and CPUs seems less guaranteed

- I also think RAM memory is a bit more sensitive to be plugged in perfectly in its slots now

- Storage drives now need to be screwed into the motherboard (in sometimes hard to reach places like under the huge CPU cooler) and possibly need heat sinks

- PCI lanes amount feels more limiting now than it used to (multiple storage drives and GPU fighting for bandwidth on the motherboard, limitations like "if you put an nvme drive here and here, then that will be disabled..."), it seems devices outgrew what even top end consumer CPU's have to offer

That's absolutely hilarious. They take a photo of something approximating your vehicle that shows your plate number, toss it in a mail system that loses more than 0.5% of the class of mail used, then according to another poster in NY they impound your car after all this.

Anyplace with the slightest adherence to the rule of law requires the state to positively identify an actual person, not a vehicle owned by a person, that is responsible for a moving violation. And then personally serve that person rather than just coming up with this absolute bullshit excuse that an unreliable mail system with a letter dropped god knows where somehow is legal service.

I've had both experiences. On some projects concise instructions seem to work better. Other times, the LLM seems to benefit from verbosity.

This is definitely a way in which working with LLMs is frustrating. I find them helpful, but I don't know that I'm getting "better" at using them. Every time I feel like I've discovered something, it seems to be situation specific.

You are repeating a bunch of "talking points" common among systemd-critics, but are not really backed up.

First of all, it wasn't "thrust upon" anyone, it was democratically selected multiple times in a ranked voting setup in case of Debian, and independently by Arch as well. It was simply because maintainers were fed up with the absolutely unmaintainable mess that predated systemd -- it seems random-ass bash scripts are not suitable for such a complex problem as booting up a system, and doing it properly is much better.

Logging sucked great time before, e.g. you didn't even get logs from before the Linux kernel is started - systemd moves it to a single place. And if you are for some reason irritated by binary logging, you can just freely pipe it to text logs.

Authentication is not done by systemd, are you thinking of pam modules? The network service is not systemd, just runs under the same group's name - KDE file browser is also different from their terminal. Also, it's not mandatory to use. Logind is not systemd itself, again. Scheduling services makes absolute sense for systemd's problem domain, so do monitoring and socket activation.

You need some kind of order to build stuff on, the Unix philosophy is more of a feel good convention than a real design guideline (and it doesn't apply in many cases)

Sure, Amazon is fast at returns and usually pretty good about processing them.

But you know what I find even faster? Not having to process a return in the first place because I actually got what I ordered and it wasn't cheap bullshit or counterfeits.

Plus it seems like half the time I'm dealing with their support because they just failed to actually seal the bubble mailer. So that two day shipping that actually took three days to show up really took me nearly a week because of their inability to actually mail things properly. 30% of my orders over the last few years have been this exact problem.

In the end sure, their support is pretty good and fast. But I've had to get their support on over half the orders I've placed with them because the item arrived damaged, the item was clearly used but sold as new, the item was a fake/knockoff, or I ended up with an empty bubble mailer on my doorstep that was clearly never sealed.

Meanwhile I haven't had to interact with support on any of the other online retailers I've used, and I placed way more non-Amazon orders than Amazon orders.

>Wake up at 4:30am

About that, what hours people that wake up at 4.30 am go to bed? If they're so conscious about their well being I'd assume at least 8 hours of sleep, so maybe they go to bed at... 8~9 pm? my question is what do they do to end their day at 9pm? If you work 9-5, you have just 4 hours left after work. Less if you commute, have dinner and a "go to be" routine of maybe 30 min. How about social life after work? Run errands? In my case, if I need to do anything out of my house it has to be after work hours (because almost everything is closed between 6am and 9am when I start work).

So, what's the secret?
by nulbyte | 2025-08-23 13:45:12+00:00
I...don't have this experience. It doesn't hold true for me, and I suspect I am not alone. There are certainly some online stores that are not very great, but by and large, I just don't have problems with them. I prefer the seller's website over Amazon.

Amazon, on the other hand, is plagued with fake or bad products from copycat sellers. I have no idea what I am going to get when I place an order. Frankly, I'm surprised when I get the actual thing I ordered.

> The file explorer drops frames, scrolling and searching cause lockups.

Yes I noticed today that scrolling a syntax-highlighted file was by far the worst it's ever been. I also noticed that typing a search query into the bar at the top of the page could not even keep up with typing speed.

Not sure about the March timeframe - for me it seems like the site went off a cliff in the last week or two.

So basically, you all looked at the surface. I can imagine some think I'm trivializing or dismissing.

There's a time for every founder where they know that the product concept is deductively right but empirically wrong. There's so much uncertainty around delivering the model to reality.

Not all things proceed from the deductively true stage, where you feel like it makes no sense to give up, to the empirically true stage. Some founders know, and I imagine they are a little bit haunted.

From the trenches, watching your body decay and hoping you can get enough empirical progress to do smart things instead of reluctantly necessary things, you just want punch anyone who has some sage wisdom to re-peddle for the 37th time. Truth, you'd like to offer decent engineers stock that you think is worth billions of dollars, but until and if it ever becomes empirically true, you just suffer and persist while people trade PG articles like cake recipes you can just follow.

This is a moment. I am tactically surrounded on all sides. The only viable option is to make a swift and decisive attack in one direction that breaks through the encirclement and reconfigures the situation. I can't win everywhere, so I have to win somewhere.

There's something to read.

Brings back memories.

But with a focus more on C++ features.

I started with Visual C++ 1.0. There were no templates.

Visual C++ 2.0 had templates.

There was by Visual C++ 3.0. They went to 4.0 to sync the MFC (Microsoft Foundation Classes) versions.

IIRC, you could use a bit of STL with 4.0

Visual C++ 5.0 was mainly optimizer differences.

Visual C++ 6.0 was actually pretty good. However it lacked partial template specialization. I was a Boost author at the time and lots of Boost code had specific workarounds for Visual C++ 6.

Visual C++ 2002 also had no partial template specialization.

Visual C++ 2003 was the first version with partial template specialization and that could compile all of Boost.

Visual C++ 2005 and 2008 did not have much changes.

Visual C++ 2010 tried to get back to 6 in the IDE (there was a deliberate marketing as such). It also had some C++11 features. But no variadic templates.

Visual C++ 2012 had no variadic templates.

Visual C++ 2013 was the first with variadic templates.

Nowadays, Visual C++’is doing much better tracking the C++ standard and often has compiler and library features before clang and GCC.

The biggest issue with Nvidia drivers, the mux chip issue, doesn't seem to be very prominent anymore these days. With modern laptops, you'll probably boot to desktop, though your experience will be terrible and pretty much unaccelerated.

Nvidia remains a problem on Linux, though they're making steps in the right direction. By putting all of their code in the secret and signed firmware, they can actually open source their drivers now, which is a lot better than how things used to be.

Still, I wouldn't buy Nvidia anything with a computer I want to run Linux on, it's not worth the hassle. Sucks that all developments related to AI are using Nvidia APIs though.

Ahh, Egghead, the one time I cracked a password (by lucky guessing).

There was a floor display computer at the shop with some random demo presentation, and to exit the program you needed to enter the password. I guessed 'egg' and it worked! I was then able to play one of the Leisure Suit Larry games which was installed on it. Fun times.
Show HN: Built a stock screener after getting frustrated with expensive tools
by tchantchov | 2025-08-23 13:49:44+00:00
After years of using screeners that were missing features or were expensive, I built this free alternative available on desktop and mobile. You can filter and sort by all the essentials:

Symbol, Name, Price, Market Cap, Change %, Change, Volume; P/E and Forward P/E ratios

Real example that saved me hours: I was searching for (cheap & solid) stocks to sell options. I filtered with PE and Forward PE under 25, volume above 1 million, price minimum $25, and market cap over $10 billion and discovered a lot of new stocks that nobody talks about on youtube or elsewhere.

Also I tried to make the design as good as I could because a lot of financial website are totally outdated in term of styling. Would love feedback from the HN community - contact us through the website if you have suggestions or need specific tools that would be useful to you

Thank you for reading & I hope you get some value from it :)

I've owned several laptops over the years and have come to regret each of my non Apple laptop purchases which never got more than 3-4 years life without some hardware failures, Surface was the worst which died after 10 months of low sporadic usage.

Whilst my gen 1 MB Air has been too slow for anything, my 2013 MB Intel still looks and runs great which the kids still make good use of. My latest M2 MB is by far the best I've ever owned with great build quality, performance, battery life where it's the first time I can confidently travel without a power brick.

Whilst Apple's non-Desktop hardware is always best-of-class, I've become increasingly dissatisfied with the direction of macOS and Windows which IMO have both become power-user-hostile and have switched to a Linux desktop full-time. Everyone's been predicting the year of the Linux Desktop for 20+ years, but I believe we're at a turning point for Linux adoption with Windows 11 becoming an intolerable ad/spyware infested marketing platform and Apple's continued ignorance of developers and ambitions of turning its neglected macOS into a locked down appliance.

Hopefully Valve can continue their investments in Steam Deck and Arch Linux to accelerate the adoption, their contributions to Proton have already IMO unblocked the biggest barrier to adoption. Whilst currently a happy Fedora user I like the direction, taste, philosophy and community behind Omarchy from what I've seen after kicking the tires in a VM, will look into switching over after they bring out their ISO.

In my ongoing solo project OS Yamato, one of the more unusual apps is Hanaco Weather — a poetic weather SNS that lets users post thoughts tied to temperature, weather conditions, and time of day.

But here’s the fun technical part: When you open the app, it fetches the real-time weather (via OpenWeatherMap API) and shows you messages from other users that match your current conditions — such as rainy mornings in Spanish, or snowy nights in Japanese.

Interesting Google-Gemini-2.5-pro seems to bias towards artists early in the alphabet and artists who’s names are alliterations.

And yeah, grok-3 seem reasonable if not boring and grok-4 is bananas.

moonshotai-kimi-vl-thinking seems to like longer names with & in them.

But what’s interesting is that the results show very shallow thinking. Either the model is trained on top ten lists somewhere, or the model is optimized for something about text of the name, it doesn’t seem like any have any kind of sophisticated understanding of what “music” is.

> probably not too dissimilar from the skill floor required to play baseball

I think baseball requires significantly more coordination than tennis.

Moreover, baseball (as opposed to just playing catch with a baseball) requires two whole teams, whereas tennis can be played with only two people.

> ice hockey

[John McEnroe voice] You cannot be serious

Ice skating by itself is difficult for beginners. They fall all over the place. Ice skating while trying to follow and control a moving puck is even more difficult.

> it's not about fitness

Ok, but in the current context, the ROI of exercise, it's all about fitness. What's the fitness ROI from table tennis or badminton? Even pickleball tends to be less exercise than standard singles tennis. And in baseball too, there's a lot of standing around and sitting (when your team is at bat). I would say that in terms of exercise, singles tennis has one of the best ROI. (Doubles not so much.)

Matching logic (simplified) • It uses currentWeather.main, description, temperature, time of day, and language. • Filters local DB messages (listWeatherComments) using: • Weather match (e.g. “Clear”, “Rainy”) • Temp range (±3°C) • Time window (±1.5h) • Language match (e.g. locale.value) • Also pulls from iOS App data (via GraphQL endpoint) and merges results. • Adds createdAtMs and sorts descending. • All matching posts are shown in the main feed — beautiful short messages from strangers in similar weather.

Two factors are at play.

This looks like it just reimplements a few Roblox APIs in an open source engine. It would of probably made more sense to just create a Roblox to Godot translator or something.

Second, your poking a multi billion dollar bear. If this project ever takes off Roblox will take action, right or wrong that's enough to stop most small projects. You can be right, but you don't have millions to fight non stop lawsuits.

In reality this is a cute proof of concept. It's never going to compete with the actual product. If it does Roblox will have it stopped in 72 hours
