Poor conversion factors may still be viable if the electricity can be bought cheaply enough and the hydrogen sold at a high enough price.
Ask HN: What's your opinion on different PaaS which keep coming up?
There have been a lot of PaaS in the past - Heroku, Netlify, Vercel, Render, Supabase etc.

Yet, new PaaS keep coming up. Some recent ones which caught my attention are - coolify.io, porter.run, ubicloud.com, etc.

Can someone who uses PaaS explain what's the rationale behind this? Which use cases are these new PaaS solving which the previous ones failed to solve?

Eventually, it seems like all these companies want to start as PaaS but get into end-to-end cloud business (including their own hardware).

Can you also comment what is preferred these days - coolify.io, porter.run or ubicloud.com - with pros and cons? If pricing is significant part of the game, how is their positioning different from cheaper clouds like Vultr.com who are also building their PaaS layer but has advantage of end-to-end control over hardware layer too?

I guess I asked more than one question but greatly appreciate an insightful answer which can help me understand this. Thank you so much.
'leather' is sufficiently unique in characteristics that there exists no better thing to compare it by which to convey the physical properties to another.

What are physical tests that are actually important to a modern day human? I don't think there's anything that can be taken to an extreme that is a good measure of an activity that is valuable to modern society.
This seems like a good trade compared to wasting hundreds of hours on a failed migration because Vercel decided beta features are ready for production.

Not to mention you’re learning transferable skills and not a proprietary stack from a company that may not exist in ten years.
If the article is anything to go by, the clue isn't as much the fuel cell itself, but the idea of having an engine that can be powered by any source of electricity. So instead of swapping out the engine for a different type, you only swap out the power storage method. If they have lithium and fuel cells now, but something else comes along later, it means a very localised change is all it takes to try it out and if feasible, put it in production.

For ICE propulsion you'd have to change a ton of things if you were to switch fuel types as the engine, the pumps, the tank, the hoses, sensors are all over the place and all have to change when you need to support a different fuel. (i.e. when switching from say, a liquid fuel to a gas or something like that) If I'm not mistaken, that's also why all the changes (not even innovation) have such small impact so far, because all they really can do is make sure that 'new' fuels behave the same way as old fuels, and new engines behave the same on the fame fuel as old engines. It's a deadlock.
This idea + Domain modeling go together like peanut butter and chocolate. The idea that an invalid state in your Domain is unrepresentable takes so much work off the database and API, and makes programs so easy to test-- since an invalid Domain representation simply will not parse, and can never make it to your API or DB, taking so much logic out of the parts of a software stack that are hardest to test.

I have never actually heard that term, and it makes me think of a custard that's been frozen, which appears to be wrong. Freezing a custard would ruin it.

But on the assumption that you mean ice cream with eggs in it, in the US that's called "ice cream", though only the flavor called "french vanilla" would usually include eggs. The eggs are the distinction between "french vanilla" and "vanilla".

Yes, because evolution, no?

Anyway, the article seems to overlook the Sixties:

> The counterculture of the 1960s was an anti-establishment cultural phenomenon and political movement that developed in the Western world during the mid-20th century. It began in the early 1960s, and continued through the early 1970s. It is often synonymous with cultural liberalism and with the various social changes of the decade. The effects of the movement have been ongoing to the present day.

It's hard to describe how crazy things got and how we live in a different world now, even the people who were there can barely articulate what happened.
The predecessor anti-virus to Windows Defender was originally meant to be released in-box with Windows XP. Due to pressure from both the US and the EU (themselves pressured by massive lobbying by Mcafee and Symantec/Norton) Microsoft was not allowed to ship the anti-virus with XP and had to release it separately on a web page as an "optional" download. This gave the anti-virus vendors an additional "free decade" (just about exactly) of being able to advertise that Windows was insecure by default and pretend like this was Microsoft incompetence.

Today a lot of average users (and as CrowdStrike has indicated, many large enterprises) still believe that Windows doesn't have built-in anti-virus because of "Microsoft incompetence" despite Defender having been bundled with Windows since Vista (2007).

Microsoft has spent decades removing security holes but doesn't get even half the credit for it because it still has to deal with an open Kernel because people want to pay for security blanket "products" like CrowdStrike's and Symantec/Norton's bloatware. That's in part because the US DOJ and the EU in trying to do the "right thing" for anti-trust reasons did the exact "wrong thing" for consumer protection reasons and left all these shady vendors with too much "everyone knows Windows has no anti-virus out of the box" PR based on Microsoft forced to remove it from Windows XP to an "optional download" and that still being the benchmark version of Windows in many minds.
There is hydrogen airport infrastructure under development, with this project aiming for commercial flights by 2035:

But it takes a decade to design and test a new airliner, so of course we should expect to hear mostly about the startups developing planes at this point.

I don't know about planes, but fuel cell cars have batteries, although smaller ones that EVs, which are actually used for the motors. HFC cars are basically EVs plus the hydrogen system.
> A few years ago, if you said you buy AMD, people would think you are hallucinating

I always bought AMD. You have to look at the (actual) numbers.

AMD was looking bad in some benchmarks due to the icc issue but the price was just better.

Intel has (had) some good stuff, but it was very expensive.
Yes, I felt the same. While the TFA highlights the "low tech" approach, and it is is undeniably cool, it looks to me more like a successful proof of concept, duct tape and all. The second video shows more detail on the attachment mechanism and my first thought was there are impressively low-friction sleeved bearing mechs which would likely broaden the performance envelope substantially. Also, I thought it would be good to have a snap-in bearing detente with a safety interlock.

The body harness isn't shown but it looks jury-rigged and bulky. There are a variety of low profile harnesses designed for stunt performers doing wire work which could be adapted. I also wondered about reducing friction at the ground plate through flattening the bottom side of the pipes and polishing both surfaces. Applying teflon sheet and/or a light coat of lubricant might further enable substantial rotational velocity to be built up. Perhaps giving the top of the ground plate a slight bowl shape would help keep the pivot point centered at higher speeds.

I think there's a lot of interesting potential with the concept and I hope this artist or others continue to explore it.

Lennart is talking out of his ass, as the implication with CrowdStrike is that the Falcon module would have been running well for a while before the content update, and would only have fallen over once the agent looked for the new content update on system and tried to load it.

Any assessment systemd could have done would see failure to boot, and would either try to roll back to a kernel with an old agent module version, which would probably do the same thing, or go back to a kernel without the Crowd Strike Module at all if available.

Computers aren't magic. They don't know things. They can't bisect their own configuration or intuit what subcomponent caused what behavior. That's your job.
Since she said she was in charge of Google Cloud's docs:

This was my recent experience when trying to use Google GCP to deploy a simple node docker application:

1. Google search, wade though SEO spam, 3 links on companies trying to sell me deployment products built on top of GCP, 2 paywalled Medium articles, and 3 out of date blog posts. Nothing I tried worked. -3 hours

2. Go to the GCP Developer documentation and feel like I'm opening up a course. Spent 2 hours looking around and reading, can't find the right commands, and the tutorial I found is out of date and doesn't work. -2 hours

3. Come back from lunch and decide to ask Google Gemini, who promptly replies with what looks like the answer but is really just made up. I correct it, and it even admits it made up an API and command line switch, only to give me more fake info. -30 min

4. Head to ChatGPT, which couldn't give me the right info (out of date from last year and obviously scraped from prior blog posts I read). -20 min

> When I see the term "ice-cream", I think of cold white creamy thing on a cone that you can buy from fast food chains. That is different from what we call "dondurma" here in Turkey. That is much softer and more creamy than "dondurma".

What you get from fast food chains would be called "soft-serve ice cream" in the US, if you want to be explicit about it. (If you want a shorter term, then "ice cream" if you don't care about the distinction, but "soft-serve" if you do.) It is not the standard form of ice cream - ice cream stores don't sell it - but it is included within the term "ice cream".

Without having specific numbers in front of me, yes fuel cells are delivering comparable power as batteries. Plus the hydrogen is lighter than batteries.

Combusting may save on some of the complexity fuel cells but you are losing efficiency in heat losses, both from the act of combusting and with gears that deliver the power to your wheels or propeller.
Woah, much appreciated! Thanks :-)
There are YouTube influencers for every niche interest.

Ask HN: Tech Jobs with Minimal Screen Time?
Writing software brings me a lot of joy, but now five years out of school, I'm starting to worry that I've made a huge mistake choosing a career that will keep me chained to a desk, staring at a screen, mostly not speaking with anyone all day.

For me, remote work has made the situation even more unbearable -- all human interaction at work is now through Zoom calls and GitHub issues. It's like pulling teeth getting coworkers to stop by the office.

What tech or tech-adjacent careers are out there that involve a better balance of screen time / physical activity / in-person interactions / impact on my local community?

history? atuin has been great.
Evangelicals think a serial killer goes to heaven if he asks God for forgiveness when the executioner throws the switch.
interestingly almost all of the original aircraft conceptualizations had a lot of props -- they got simplified due to the realities of drivetrain complexity pre-electrification.

redundancy is one reason, weight is another, cost is another. Lower amperage smaller motors require less copper and battery capacity, they're cheaper to produce, they can be placed opportunistically to maximize wing efficiency, and they're quite nearly COTS.

bigger props necessitate more power in a singular spot, bigger heavier motor and cooling solutions, so on and so fourth. lots of motors at lower duty cycle can reduce these burdens, and if done right may even be able to get rid of the cooling systems and associated weight entirely.
I would guess there also may be a difference between the two cases in that the force needed to break a leg wasn’t measured by compressing it, but by exerting force perpendicular to its length.

Even if it isn’t, there are so many ways to measure breaking strength that it’s unlikely the two cases are perfectly comparable.
> Hydrogen is a terrible battery. Best case conversion to H2 is ~80%, while best case fuel cell efficiency is ~50%. That's 40% round trip while most batteries can do 90%.

While there's no arguing with the physics here, don't forget the economics either. The price of electricity in Denmark on a cloudy, windless early evening can easily be 10 or more times the price in Newfoundland. Then start factoring in that a plane carrying hydrogen is significantly lighter than a plane carrying batteries.

While you might be using 10x as much electricity at the point of generation, you're paying a lot less for it, and you're using it more efficiently.
Yeah, Apple doesn’t allow any user code to run in kernel mode without significant hoops (the kernel is code signed) and tries to provide a user space API (e.g. DriverKit) as an alternative for the missing functionality.

I mean, you could say the same thing about art. What value does art provide? We don't need it for survival.

Alternatively, look at Olympic weightlifting. While the weights used in the clean and jerk and snatch are less that used in the squat in powerlifting, the instantaneous forces are much greater. I don't think 1300 lbs is anywhere near enough to break a human femur if we're talking compressive forces, lateral force is a different story.

I doubt rewriting the Linux kernel to "fix the efficiency and scaling issues of threads" is possible, but even if it is, the Rust experts who figured out how to get Pin to work are presumably not the same as the set of kernel experts who would be capable of doing so. So what do you think they should have done, concretely? Just thrown up their hands and said "well, we won't add async to our language, because in theory someday someone might fix Linux to make threads magically fast" ?
So they don't have to pay the license.
