Launch: Teaching the next generation of engineers through Mindustry and Factorio
Hello, Hacker News community!

All of us gamers can trace some of the most profound "a-ha" moments to gaming—whether it was mastering resource management in Command & Conquer, solving intricate puzzles in Monkey Island, navigating the economy of WoW's auction house, or spending countless hours building in Minecraft. These experiences didn't just entertain; they were among the most educational of our formative years.

The dream has always been as simple as seemingly unattainable: a game-based education program that works.

That's why we've engineered -pun intended- an educational program that lives up to that dream. Using Mindustry and Factorio as our tools, we're teaching the next generation of engineers to think critically, collaborate effectively, and solve complex problems. The results are insane.

Why Not Just Let Kids Learn On Their Own?

Some certainly can and will! Self-directed learning can yield great results.
Here's our take: if you put ten kids together in a playground and give them a basketball, they might end up playing, but if you put a great coach in the mix, all of a sudden it's a different league.

Our program provides the guidance to focus efforts, accelerate learning, and most importantly, foster a community where kids are inspired to tackle challenging problems together.

We've designed this program for kids aged 10 and up, particularly those with an engineering bent. Our aim is to harness their innate curiosity and inspire them to do hard things. As simple as that.

We're excited to hear what the virtual streets you grew up in are and what your thoughts are on game based engineering education.

What's the smallest diesel generator that can charge an electric car to 20% (in less than a day)?
My next car will be a Tesla but not for the ICE vs Electric reasons.

I am in Toronto and car theft is very common here as our Ports have very lax security. Toyotas top the list for stolen vehicles. And Teslas are the least stolen vehicle. I wish Toyotas were harder to steal.
Me neither. I've rarely felt my M1/M2 laptops getting hot. On the other hand, Windows laptops like my Intel i7 XPS would get hot just from booting.
This is one of those monumental strategic decisions that with the benefit of hindsight seems obvious. No charging infrastructure means no EV market (simplifying).

Boeing and Airbus had a similar situation - increasing passenger numbers to Airbus meant “we need to build giant planes like the A380” (now essentially dead). To Boeing it meant “we better build planes that can service smaller airports because they’ll become increasingly important”.

Mind boggling how the wrong interpretation of the market situation leads to decade-defining trajectories for companies.

I really want to like it. I am well accustomed to dealing with quirky FOSS UIs. But it is so bad. Something that takes one click in Solidworks or Solid Edge takes ten, and at any point if there is an error, there is no feedback.

If it looked like FreeCAD was trying to improve the UI I think I'd be throwing some money their way to fund it. But it appears they're happy with the way it works, as these paper cuts have actually gotten worse over time.

It's just FreeCAD, not FOSS-CAD-as-a-whole. Kicad gets better and easier to use each release and I am well aware what a gift it is to engineering work.

I don't think the use case for this is as general as most RPC systems.

The linked site envisions a situation where you had an app running on one server, now you want to break that workload up while making the absolute minimum number of code changes.

All the clients and code would still be controlled by the same team.

Students enrolled in community colleges also expressed concern that they lost access to their devices immediately before winter quarter finals.

Not exactly a non-story… one women’s prison was put on lockdown so the laptops could be seized.

I still see people, in 2024, writing new software and using XML as the data format. I don't have an example offhand, but I recently saw a hobby game engine using XML to store its engine-specific game object/scene data.

Personally, I like to use TOML for anything that is likely to also be edited by humans and JSON or binary for something that will only ever be used by machines.

> the M3 Air seems like a step backwards

The reviews certainly don't say so.

> The M1 and M2 generally performed the same for light and medium-sized tasks whether they had active cooling fans on them or not, and the M3 acts the same way.

Compared to the M1, a fully enabled M3 with eight CPU cores and 10 GPU cores running some typical benchmarks has roughly 25 to 30 percent faster single-core CPU performance, 35 to 40 percent faster multi-core performance, and between 45 and 65 percent better graphics performance, depending on the test.

The numbers speak for themselves, though—however fast it throttles, a passively cooled M3 runs faster than an M1 or M2, and it stands up well against modern actively cooled laptops with Intel and AMD CPUs inside. But if you regularly stress the CPU and GPU, you're probably leaving a bit of the M3's performance on the table relative to the same chip in the $1,599 MacBook Pro.

I'm not opposed to "folks" in the abstract, but I would honestly say the opposite of what you just said: "people" is entirely neutral, while "folks" is often used specifically to signal which side of the culture war the speaker is on.

It's a shibboleth that says to others that you've been told that "people" has negative connotations and you are willing to adjust your speech based on what you've been told, but said negative connotations are not actually present in any dialect of English I've ever heard spoken.

It does sound very much like an overreaction, from the manufacturer of these devices.

"The man who made the devices said there’s little someone inside could actually do with a hacked Securebook. They’d need to fashion a USB port, be able to install another operating system, and get access to a docking station, said Jeremy Schwartz, Justice Tech president. Even when the devices are docked, they’re not connected to the wider internet. "

The throttling can be problematic when you’re doing all of those things plus attempting to screen share on a video call, in my experience.
It's not even just that people are only willing to buy Toyota hybrids. In some places in the US Toyotas are just about the only hybrids one can easily buy. Good luck buying a Ford hybrid if you're not in California, practically none are allotted to my area.

For me, it’s a provider installed ONT on the side of the house. This converts fiber to Ethernet that runs inside my house. I then have just a port to plug my router into.

Now, the provider trying to bundle a router is another question… but the ONT isn’t something I’d like to buy. And on my invoice, it isn’t even listed as something that I rent.
It might be exaggerated, and the Apple Silicon MacBooks still fall behind as soon as gaming or other GPU-centered tasks come up.

No connection to either company, but for what it’s worth I’d never in a million years consider Windmill and this product to be direct competitors.

We’ve had a lot of pain with celery and Redis over the years and Hatchet seems to be a pretty compelling alternative. I’d want to see the codebase stabilize a bit before seriously considering it though. And frankly I don’t see a viable path to real commercialization for them so I’d only consider it if everything you needed really was MIT licensed.

Windmill is super interesting but I view it as the next evolution of something like Zapier. Having a large corpus of templates and integrations is the power of that type of product. I understand that under the hood it is a similar paradigm, but the market positioning is rightfully night and day. And I also do see a path to real commercialization of the Windmill product because of the above.
Thank you for the steer to that article, it has some errors.

ECN is not in use at starlink (yet), so far as I can tell. The AQM in place just uses conventional - and timely - packet drop, which is the principal signal for congestion control across the internet. (so I would say " alternatively" in the Wikipedia article about ECN, and drop principally)

To this day, so many people (including the early engineers at starlink), do not get that dropping packets is how we manage latency across it for greedy flows. I have given so many talks about how this works - lose 2 minutes of your life to this, please: https://www.youtube.com/watch?v=TWViGcBlnm0&t=995s

Starlink folk now deeply get that buffering for 100s of Ms is counter productive, and have put in play many "bufferbloat" mitigations over the past year, focusing on P99 metrics in particular.

...

More importantly than AQM, their stuff does "flow isolation" and "Fair queuing" so that fat flows interfere with lighter weight flows less. https://en.wikipedia.org/wiki/Fair_queuing

The starlink wifi now does fq_codel in particular, which combines fair (flow) queuing with the codel AQM. While I do not have any benchmarks of their implementation it should show up on tests where two or more stations are trying to "do stuff" at the same time.

...

There has been a lot of hype about ECN lately (because it does not require dropping packets) but it needs to be enabled at the endpoints, and at the congested routers in-between running an AQM algorithm that also has it turned on. I do keep hoping more enable it on their OSes (apple has it on for some sites, Apple Quic does now), and more routers enable it also.

Stunningly widely supported is RFC3168 ECN across 68% or so of all websites, but few clients turn it on. Here's how you can try it:

If you have a supported router leveraging SQM ( on any tech, fiber, docsis, what have you) : https://openwrt.org/docs/guide-user/network/traffic-shaping/...

I note that ECN has some major drawbacks vs a vs drop - a bad guy can abuse it, in particular, which is in part why it is not on by default. If

As someone with relatively little knowledge of machine learning, an overview of mvs systems and a desire to understand what these people have done, does anyone have any suggestions on where to start learning so that I could play with the ideas within one lifetime?

Ask HN: Your opinion on Edge Computing and Servers
Hello everyone! I'm sorry in advance if the same question was asked and discussed before, but I'm genuinely looking for your thoughts and experience.

I'm working on a project for simplifying architecture and deployment approaches and workflows, very similar to railway.app, but with more focus on freedom of building more customizable architectures, while being open-source and easy-to-use without touching terraform, k8s, aws and stuff like that (could be described better, I know, but not that important for this topic).

The point is, lately, everything seems to shifting to the "edge", at first I thought of it as a very cool way to do frontend, then, all your computing and now with things like turso and FLAME by fly.io you can theoretically forget about servers in more classic definition at all.

Another thing is more abstraction, perhaps we should treat it like going from actual hardware to VMs back in the day, but something rubs me the wrong way, when I think about deploying everything on some infra, that is very hard to replicate on your own, instead of having almost identical linux boxes available from numerous providers.

Don't get me wrong, I'm really happy that we as an industry are moving forward and coming up with new cool things, but what are your thoughts on the near future? Will "classic servers" be treated like php (still used a lot, but not by new projects)? Or will we have another throwback, like what happened with SSR, htmx and statically typed languages?

I know that all we can do is speculate, but I think that insights from different people can help us build a more solid picture of what's going on today and why.

Please keep in mind, that I'm not rooting for crazy micro-services, 10 year old monoliths or huge dev-ops teams, I prefer simplicity, performance and generally always excited about new ideas. I don't know if my brain is acting defensive about the things I'm working on, or is it my linux-user soul ranting about "proprietary XYZ", or it's just the way things go and I should stop bothering?

Thanks to everyone in advance for your thoughts and opinions! And again, sorry if this post is repeating older discussions (I'm not a HN regular).

> They're much better at not emitting CO2, for example.

They are better, but not necessarily much better. A Toyota Prius Prime can get 39 to 44 miles in electric mode [1]. That's good enough for the average person's daily commute or weekend errands, which constitute the vast majority of the miles driven by people. The end result could be a reduction in emissions by 95%. Not 100%, true. But that 100% reduction of an EV is mostly a shifting of emissions to some central power plant, and since electricity is fungible, one can't really say that that particular power plant is solar. In other words, the difference between the overall emissions of an EV vs a good plug-in hybrid (like the Prius Prime) is negligible.

lastly, it is not just TCP that AQMs can control, but any TCP-friendly congestion control - Quic - which is udp based - plays by those rules. Most of our videoconferencing applications in their bandwidth seeking phase, also.

I think you've done well.

Personally my Model S had all sorts of issues, I sold it before the warranty period ended as I knew that I didn't want to pay dealer prices for everything and deal with the bottlenecks.

I just can't see a Model S actually being on the road when it's 15-20 years old because no-one is going to want to pay Tesla prices to maintain it.

The relevant comparison is with a ~2020 Civic i.e. when both cars are 20 years old, which one will still be going.

> For instance, maybe thinking-about-meaning isn't such a bad distraction, and if that's the distraction I pick, we're back where we started.

In particular, concern that taking on a great task might demote the prominence of or drive for thinking-about-meaning in one’s life seems to me a sign of having gotten a bit lost in the woods and seeing only trees, if you will.

I think that sort of activity makes a better prologue and occasional footnote than it does a story, and that doing is both greater and much harder than thinking—which is why centering thought per se is such tempting bait. Many great thinkers warn of this :-)

Having meaning beats seeking meaning—the latter’s not much of an end, and doing less of it for having occupied oneself with meaning isn’t a loss.
I strongly agree that there is a difference between science and "science".

>Science can be trusted. Measurements and the testing and retesting can be trusted.

I still wouldn't go so far. Science doesn't provide a pure understanding of the world it produces at best a model based on observations and axioms. These both can be wrong without politics,money, or personal bias. Our senses are fallible and sometimes you measured the wrong thing with the wrong tool. You shouldn't trust science, you scrutinize it and use what you find works until it doesn't (and then publish that).
