I've always been fascinated by the power density potential of the gas turbine. Especially the micro turbine class.

> The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. [0]

> A similar microturbine built by the Belgian Katholieke Universiteit Leuven has a rotor diameter of 20 mm and is expected to produce about 1,000 W (1.3 hp). [0]

Efficiency is not fantastic at these scales. But, imagine trying to get that amount of power from a different kind of thermodynamic engine with the same mass-volume budget. For certain scenarios, this tradeoff would be amazing. EV charging is something that comes to mind. If the generator is only 50lbs and fits within a lunch box, you could keep it in your car just like a spare tire. I think the efficiency can be compensated for when considering the benefits of distributed generation, cost & form factor.

One of the other advantages of the smaller engines is that you can use techniques that are wildly infeasible in larger engines. For example, Capstone uses a zero-friction air bearing in their solutions:

> Key to the Capstone design is its use of air bearings, which provides maintenance and fluid-free operation for the lifetime of the turbine and reduces the system to a single moving part. This also eliminates the need for any cooling or other secondary systems. [1]

America did used to have real diplomacy, in the sense that there was an active dialogue between diplomats in America and their counterparts abroad. During the unipolar moment, they gave that up. That's beyond dangerous and frankly suicidal.
You have to meet your users where they are. Your users are not using nix and bazel, they're using npm and typescript.

If your users are using bazel, it's easy to separate "download" from "build", but if you're meeting your users over here where cows aren't spherical, you can't take security that seriously.

Security doesn't help if all your users leave.
Seriously, I absolutely can't stand the azure ui. I don't think the AWS console is great, but it is definitely better than the Azure one to me.
is it because there are features that AWS provides to you that are not available in GCP, or just the fact that setting up exact replicas of processes is hard for migrations like these?

I disagree. When I prompt for Go, I request that it be written in the style of the Go standard library and Go authors. This very much changes the style of the output.
Exactly.

I feel people/hypers keep rumbling about many things and way too often seem they have no real life experience.

The biggest problem I’ve seen over 20 years long career is people and the games they play (on different levels of leadership and management within an org) and their inability to agree to and then verbalise what on Earth they want. No matter is it a greenfield or some digital transformation project, they a plagued by fear and self-interest (of various kind).

And even if/when they identify a problem (e.g. games players) it becomes a risky cutting the cord since the one needs to identify who to rely on to clean the mess and their confidence caves in (often) while resolving to “let’s layoff x number of ‘leaf’ employees” is safe scared-with-no-vision leader move and it looks good on the stock market.

Software engineers (generally) kept delivering despite all that for years across the board (generally). And, generally, kept their values and principles and that bothers this managerial class a lot it seems and they (in a way) can’t wait to stop paying “those nerds” big salaries and that’s why those often low values and unprincipled people can’t wait to see our backs and are getting hyped about this “AI will replace SD/SE” mantra.

All this above is obviously generally speaking but yeah we people tend way to often to misplace our focus and solve lesser priority problems, and this “ai replacing engineers” is one of them to a good degree.

And for the majority of software developers there is nothing to worry about. The sheer keep-knowledge-up-to-date demand this industry put on us primed us to be by far the most able professional group to jump into a career change in no time.

Which other group in huge numbers can just sit down and learn and work for 10 hours a day 7 days a week and not complain or get emotionally disturbed (too much) and get the thing but us.

So in the worst case scenario we will be fine, others should be scared if we in numbers pick their industry to move into.
It’s a shame that even by living on a deserted island with minimal internet, people are corrupted by politics. I mean all of the earths governments could collapse and this guys life would hardly change, yet he cares about Ukraine and the global economy

Just getting into a home loan pre-rate rises is the biggest advantage, due to the fixed-rate nature of home loans in the US.

This article is another restating of the fact that wealth inequality is the greatest its ever been.
I would also use the axis of how easy it is to tell if it’s wrong. If you ask an LLM for code and you quickly get a syntax error or the wrong result, it’s not going to waste much time or, usually, make you look bad. If you ask it to do some analysis on a topic where you don’t have enough knowledge to tell if it’s right, however, that’s a lot riskier because you get the negative reputation.

This is the big problem with Google’s AI results: before, the wrong answer was from seoscum.com and people would learn to ignore them. Now the wrong answer is given Google’s corporate reputation and also there’s no way to conditionally distrust it so you learn not to trust them for anything.
It's "facts don't care about your feelings". As the originator of the quote shows himself, his feelings are still very important and must be cared for.
It may be relevant that Mozilla recently acquired a Meta-created ad tracking company and is now awash with Meta ad execs. [0]

It may also be relevant that Meta is recently upsetting people in Europe for tracking and targeting people in spite of Europe's data protection rules [1].

My guess (and this is just speculation at this point) is that Meta and Mozilla think they're being clever and getting away with some "private" ad tracking and are underestimating how much damage they're doing to Mozilla's reputation.

I doubt the Anonym tech has been built into Firefox yet, but it's clear that the corporate strategic direction is to bet on some concept of "acceptable ads" like Google did in the 90s.

HPC was always a tough sales area for Red Hat and RHEL.

In general, while RHEL is obviously still an important revenue source, there's also a lot of focus on OpenShift going forward which has done of pretty good job of covering (and more) inevitable RHEL declines moving forward.

Mozilla can't be trusted to spend their money in a way that improves their browser or their market share. We will never know, but I think Mozilla would squander $100M/year from users. It makes me sad because I have been a fan of Mozilla and Firefox for most of my life.
Your story reminds me of when Microsoft acquired Hotmail in the '90s and they tried migrating from FreeBSD & Solaris onto Windows NT/IIS. Having the world's largest email service running on the Windows stack would have been a huge endorsement. It took years until they were successful.

Show HN: Start GPT threads in ChatGPT (& other sites)
I noticed current LLM chat apps don't support threads for follow questions, but instead they're one long conversation. Often when I'm digging into a topic and GPT responds with a book, I want to ask follow-ups in "side chats" that I'd prefer to be inline and in context rather than jumping to bottom of the page, so I created GPT threads.

It's a chrome extension where you can highlight some text and start a chat focusing on that text and incorporating surrounding context. You can have multiple threads on a page, and the extension has configurability like surrounding context size, response lengths, chat box positioning.

I've found it useful for other sites too to quickly ask questions about news articles, docs, or HN threads!

If they would simply tell us what part of Firefox is affected by the CCPA's definition of "selling user data", there would be no room for misinterpretation and this would be over.

If it's as innocent as "Firefox has to send HTTP packets to arbitrary web servers to achieve the fundamental function of loading a page" and that web server is considered 3rd party by CCPA, then everyone would understand... this is either poor communication or they are hiding something else (which everyone should rightly assume in this day and age).

Just tell us already Mozilla!
> People with houses today will be the aristocracy in a few decades

Not really. Peasants were mostly owning their houses, that did't make them aristocracy.

I genuinely do not see how owning a 1970s-built bungalow translates me into the aristocracy in a few decades.
Brits and Europeans died for America's last two wars, on a percentage basis more Dutch and Canadian troops died than Americans. Nearly 500 British troops died for your war.

Next time America asks for assistance, whether it's troops or firefighters I hope the attitude is reflected back and it comes with a costs+ invoice due up front.

It’s a JavaScript/node-like environment only right now no? I love it for my svelte site but it’s a massive limitation to be locked in based on language and request-response based constraints right now.

You need at the very least containers and persistent volumes to be interesting to me at least.
So this friend escaped from the ephemeral container VM into the build host which happened to have a private SSH on it that allowed it to connect to a bastion host to... go back to the build host and debug a failed build that should be self-contained inside the container VM which they already had access in the first place by the means of, you know, running a build on it? Interesting.

I agree. I think he meant Rc/Arc.
You don't have any confidence beyond what lockfiles give you (which is to say the npm postinstall scripts could be very impure, non-hermetic, and output random strings). But if you require users to vendor all their dependencies, fully isolate all network traffic during build, be perfectly pure and reproducible and hermetic, presumably use nix/bazel/etc... well, you won't have any users.

If you want a perfectly secure system with 0 users, it's pretty easy to build that.
>People in advanced economies stand to inherit around $6trn this year—about 10% of GDP

this is mixing apples and oranges. Let's say the stock market yields 10% annual returns on average (it doesn't, but it's a round number in the ballpark). Let's say you inherit a million dollars. That million dollars invested in the stock market would return $100,000 to you as annual income. THAT number is comparable to GDP which is a measure of income. So, in other words, "people in advanced economies stand to earn annually from their inheritances less than 1% of GDP (yawn) not 10%"

other nits, the baby boomers were an unusually large population group in an unusually prosperous and healthy period of history: we've known they would die for quite some time and we've known they would leave a lot of money. It's not "a trend" and it's not "news". It's a well known anomoly, a blip/bulge passing through the system. It's interesting but it's not alarming.

The commanders estimated that 50 to 70 per cent of new infantry troops were killed or wounded within days of starting their first rotation.

So if they don't have manpower OR enough weapons, maybe when their head of state comes to ask for support from their biggest benefactor, he should, I dunno....not piss off his host? Wouldn't that help him get what he wants?
> What's your argument, that it shouldn't count because it probably didn't affect the outcome very much?

No. My argument is that "being in favor of prop 8" is a defendable PoV.

Firing someone for political/religious views much less so.

> You don't think it creates a hostile place for workers when their CEO is trying to deny them basic right?

1) No. Calling state sanctioned marriage a "basic right" is IMO a stretch in the first place, but lets put that aside: Say Eich had voted for a proposition that was actually in favor of taking basic rights, like raising voting age to 21. Would that have been a reason to cancel his career five years later? Don't think so; does not affect work at all. Its your CEO, not your drinking buddy, and even in drinking buddies someone with conflicting or opposite political views can make for more interesting discussion; I see no appeal in spending life in an echo chamber.

2) It was not a cancel campaign championed by people actually affected, but "white knighting" instead (people very publicly advocating for issues that don't affect them, frequently without even any feedback or involvement from the actual victims). Might be wrong here and dont know everything about everyone involved, but thats what it looks like to me (judging mainly from John Lilly).

3) Running a cancel campaign like this is not gonna make everyone feel safe. People are just gonna try very hard to never be in the "outgroup" instead, with all the detestable social maneuvring that brings. No thanks. Would rather face honest bigotry than fake smiles, a bunch of lies and raw contempt behind the back.
Think of it this way, if I took 1lb of air on the ground and put it into a box that box would have sides of x. As I go up x gets bigger because pressure is dropping with altitude so to get the same mass of air I need a bigger box. When you burn fuel you need a ratio of fuel to air that is determined by mass, not volume so I need to take that really big box at altitude and squeeze it down a lot to get the same density as at sea-level (and then squeeze it even more to get the right mixture in the combustion section). The thing is though, 'hot air rises' so just squeezing down to 1 atmosphere of pressure air at altitude is way hotter than the air on the ground and then you squeeze it even more to get it to the density you need for the engine and it is -really- hot. Engines are generally torque limited on the ground and TIT limited at altitude because as they go up you are power limited by TIT (turbine inlet temp, or some other temp limit related to the engine) because of this compression. Designing engines that can handle that massive heat and that massive force is really hard, but electric has the huge benefit of just needing to produce torque so it is way easier to build and can keep producing power at much higher altitudes. There are definitely challenges there, but they are likely much easier than solving both the heat and torque problems that jet engines have.
Facebook is sort of tech’s Enron / McDonnell Douglas.
this is not true. There was Svoboda and Azov, and very little else.
If Google didn’t tell you the job involved unpaid overtime before you accepted, they’re giving you a pay cut now. Like any other business deal, that should happen in writing.

Even tech workers who mistakenly thought they were “too smart” to need a union actually need a union to balance out the uneven negotiating power. The house always wins.
You can't since a large number of npm post-install scripts also make random arbitrary network calls.

This includes things like downloading and compiling pre-compiled binaries for the native architecture hosted on random servers.

npm is really cool.
Hey, congrats! Spent a good chunk of time fiddling with indie games… as some others have mentioned Jesse Schell is cool, also Ralph Koster. I know you’re looking for communities/resources, been there! But the best thing to do, is make games repeatedly. Apologies in advance for the length, but this is a part of my life I genuinely wish I could reset and retry w/ hindsight bc it feels so obvious now!

I found trying to make demos of individual mechanics pretty critical. Like any design process: high volume, low(er) fidelity until you find a meaningful direction (best case: lots of play testing from folks who are not the creators)

Even really abstract approaches for balancing XP a character, or moving on screen in a unique/tricky way can be useful to look for a signal of enjoyability (which option do folks want to replay, which do they seem less interested in… and why?)

I often try to think about the “play” part (pure delight/fun) vs the “game” part (winning conditions, confounding advantages, etc) separately

Last, I enjoyed talking to people (including myself) and trying to dissect WHY they like the games they like. There are genres and typologies that can be interesting creative inspiration (a game with a sudden-death condition mixed with the thrill of a race)

Try to make COMPLETE demos (beginning, advancement, winning conditions) and also honestly concept art (tell the visual story, we eat w our eyes first)

And just have fun! Man I am jealous, no time for games these days :/
That doesn't follow: Ukraine has the international legion (probably about 3,500 people in country last I checked) and a number of Russian groups fighting on behalf of Ukraine.

The only thing Chinese nationals fighting for Russia tells us is that China is not expressly limiting freedom of movement to do so...but there has also been at least 1 American who tried to join Russia to fight Ukraine (and was tortured to death by the Russians on suspicion of being a spy for his trouble).
There's a world of difference between what Erdogan says and what he does. And you should only look at what he does.

For example, since October 7, Erdogan made lots of statements about how he was upset with the Israeli treatment of Palestinians. That was all for show. Something like 40% of Israel's energy comes from Azerbijan and transits through Turkey. Turkey could've cut that off. But they never would.

Likeise, Erdogan's family continued to trade with and make money from Israel.

Turkey buys a Russian anti-missile defense system [1] while selling Bayraktar drones to Ukraine and hosting US (technically NATO) nuclear weapons.

Turkey is consistently aligned with US foreign polciy with some minor exceptions that are really deviations tolerated because of Turkey's strategic importance and recognizing the need for Erdogan to maintain power.

There is no "fascination." Many people have political and cultural views which are commonly considered to be "leftist," as we live in a (supposedly) democratic republic in which people have the right to express their views and have them represented in government. In the common American parlance that term is so broad (because it's mostly used as a pejorative) and the overton window has shifted so far to the right that "leftism" now encompasses most of the ideological and political spectrum.

But I could tell by your second sentence that you're neither willing nor able to engage with nuance and have an intelligent conversation on the matter. We wouldn't even be speaking the same language, so I'll leave it be.
I can't post things like "what a bunch of clowns" due to hacker news guidelines so let me go by another more productive route.

These people, the ones who install dependencies (that install dependencies)+, these people who write apps with AI, who in the previous season looped between executing their code and searching the error on stackoverflow.

Whether they work for a company or have their own startup, the moment that they start charging money, they need to be held liable when shit happens.

When they make their business model or employability advantage to take free code in the internet, add pumpkin spice and charge cash for it, they cross the line from pissing passionate hackers by defiling our craft, to dumping in the pool and ruining it for users and us.

It is not sufficient to write somewhere in a contract that something is as is and we hold harmless and this and that. Buddy if you download an ai tool to write an ai tool to write an ai tool and you decided to slap a password in there, you are playing with big guns, if it gets leaked, you are putting other services at risk, but let's call that a misdemeanor. Because we need to reserve something stronger for when your program fails silently, and someone paid you for it, and they relied on your program, and acted on it.

That's worse than a vulnerability, there is no shared responsibility, at least with a vuln, you can argue that it wasn't all your fault, someone else actively caused harm. Now are we to believe the greater risk of installing 19k dependencies and programming ai with ai is vulns? No! We have a certainty, not a risk, that they will fuck it up.

Eventually we should license the field, but for now, we gotta hold devs liable.

Give those of us who do 10 times less, but do it right, some kind of marketing advantages, it shouldn't be legal that they are competing with us. A vscode fork got how much in VC funding?

My brothers lets take arms and defend. And defend quality software I say. Fear not writing code, fear not writing raw html, fear not, for they don't feel fear so why should you?
What's the history of this model? Was it organic, or was it planned from the beginning (or maybe a bit of both)?

It's impressive when relatively small rules can so effectively set the vibe. I suppose you could claim you set rules that are well aligned with the eigenvectors of a nerd.
You seem to be confusing the concept of "ownership" with that of "private property" (on immovables, especially). The "Marxist notion" of personal property still requires the concept of ownership.
