ragebol··on GPS and the Lost Art of Getting Lost
How does pone drive 20 hours in the wrong direction, when trying to go to an appointment 19km away?

What must go wrong when you are allowed to drive and not realize that mistake after at most an hour or so?

ragebol··on Discovery Loop
Same amount of humans means no cost savings. More science is hard to value, while less salaries paid is easy to value.
ragebol··on Wind and solar overtake fossil fuels in Germany for the first time
Ah, thanks, had to be something like that indeed. Had a hard time imagining putting work into an ICE and getting anything useful out.
ragebol··on Wind and solar overtake fossil fuels in Germany for the first time
I don't see why that would be the case. Why is the 20% of eg. an internal combustion engine coupled to the 500% COP of a heat pump? I see a vague connection as an ICE also uses expanding gasses etc, but that's about it. What am I missing?
ragebol··on Wind and solar overtake fossil fuels in Germany for the first time
True. For residential heating, heat pumps make for a similar ratio as they make 3-5 units of hear for 1 unit of electric energy, depending on conditions.

The challenge in heating is industrial heat, which is much hotter. Can't do that with heat pumps (yet?)

ragebol··on Wind and solar overtake fossil fuels in Germany for the first time
When looking at hat kind of graphs, it's good to keep in mind that burning hydrocarbons is relatively inefficient: only ~20-30% of the energy in the fuel turns into useful work, while electricity is much, much more efficient. So, we need much less of it.

Still a long ways to go regardless, but much less bleak. And also, exponentially growing deployments of wind and solar are harder to spot on this 2-year old graph which goes only up to 2024.

ragebol··on Software for One
Since the advent of these coding assistants, I gathered a list of software tool ideas I usually discarded due to lack of time. No more! Main one on that list: grocery assistant, with a barcode scanner for empty packaging to order new stuff, inventory management, coupling to recipes and most importantly: automatic ordering for delivery.

There's existing stuff for this but making a personal extension to this should be very well possible too.

ragebol··on The AI trade now runs on borrowed money, and the lenders are repricing it
Maybe so. That leaves just the hardware. Deprecates badly. Maybe gamers will take it off their hands gladly?
ragebol··on The AI trade now runs on borrowed money, and the lenders are repricing it
Yes, they have assets: GPUs sitting in datacenters, and data.

Question is: is that worth enough to cover the debt after the market crashed?

ragebol··on A.I. companies are recruiting electricians and carpenters by the thousands
I would have thought this would be about electricians and carpenters with camera's on their heads to train AI. Apparently not yet. Imagine robots (humanoids or something more specialized) building datacenters...
ragebol··on Shinjuku Station in 3D
My wife had a terrible fear of loosing me in this station, afraid she would loose me and never find me back :-) .

It felt like the biggest station we knew before, multiplied by 10 and then molded and warped like a ball of dough.

IIRC there is a multi-level bus terminal at this station too that we had to use to get to Narita airport, which we had never seen before for a bus terminal.

Would love to go to Japan again, but when the kids are a bit older and we don't have to fear loosing them in this station.

ragebol··on Do we just want slaves?
We just want work done we don't want to do ourselves.

Whether it's slaves, animals or dumb to smart machines and anything in between, that is an 'implementation detail'.

ragebol··on OpenAI ‘in early talks to give 5% stake to US government’
Coming back for another 5% seems unlikely. But the whole thing is unlikely and uncommon, so what's it matter?
ragebol··on OpenAI ‘in early talks to give 5% stake to US government’
Exacerbated by nothing being normal with this administration, to say the least.
ragebol··on Why jet engines aren't made in China
> I may have picked a bad example, but the principle stands.

I know electric aircraft are not quite feasible on the same scale as airlines.

On the other hand, China has an extensive high-speed rail network for inland travel. OI have no idea how often the Chine fly inside the country vs how often they use aircraft, but this is the sort of different technology for the same purpose I mean.

ragebol··on Why jet engines aren't made in China
I'd expect the competition for these companies to come in not from someone using the same technology, but a different technology that serves the same purpose. Eg. what happened to Kodak and Nokia.

For jet engines, the only thing that comes to mind is electric aircraft. No single-crystal turbine blades needed at all.

I may have picked a bad example, but the principle stands.

EDIT: China has an extensive high-speed rail network. While those don't quite cover intercontinental flight, it is the sort of paradigm shift I mean.

ragebol··on OpenAI ‘in early talks to give 5% stake to US government’
Besides direct control, what could a dividend on the profits do what a well-proportioned corporate tax on profits cannot do? The state would only get dividends assuming it would not sell shares.

And the state can exert control much more fairly (ie. to all competitors as well) with regulation and laws.

Regulations and taxes are seen as 'un-american' I suppose, while giving stock to the government is not somehow?

ragebol··on GLM 5.2 beats Claude in our benchmarks
I'm using DeepSeek v4 Flash through OpenCode and OpenRouter, and works just fine. It's not the bottleneck, I am, for what I'm building. That involves understanding the problem I'm solving, checking correctness

Meanwhile, it's such a cheap model that I've spent not even $25 over 3 weeks.

ragebol··on Show HN: Are You in the Weights?
According to Kimi, I'm a Dutch robotics engineer. Got that part actually right! Not so much for the rest, about First Lego League. But I did RoboCup, so close enough I guess.

The other models think I'm Dutch (I guess the 'van' gives that away?) and am a soccer/football player. I don't know anything about soccer though

ragebol··on Challenging the Narrative of European Decline
It will be a spectacular crash if/when it crashes. But there is this old adage of 'the market can remain irrational much longer than you can stay solvent'.

I'm not holding my breath for this bubble.

ragebol··on Challenging the Narrative of European Decline
> 10% of the US economy is IT

The US is the IT-supplier of the world. I don't know how large a % of that comes for outside the US. But with all the 'shenanigans' of the Trump regime and the trust the US has lost due to that, that should lead to losing IT business from the rest of the world.

In other words, If Europe would disavow using US IT, as would be the wise choice I think, then Europe might close the gap.

I just hope this is not just wishful thinking though.

ragebol··on Qwen-Robot Suite: A Foundation Model Suite for Physical World Intelligence
How many people have homes that require chores to be done? Laundry, cleaning, setting/clearing tables, yard work, some consider cooking a chore.

If I could get an affordable robot to do a subset of them, I'm in the market for one.

ragebol··on How JPL keeps the 13-year-old Curiosity rover doing science
If a few years it'll be old enough to drive a car. That'll help exploration!
ragebol··on Ask HN: What are tools you have made for yourself since the advent of AI?
If anyone wants to play, go to https://live-battlefield.ngrok.app/join/uag-fav-dzs and if there's a bunch of players I'll start a game sometime this evening (some 8 hours from now).

I had OpenCode with DeepSeek V4 Flash create a quiz about the HN FAQ, so use that to earn bombs :-)

You will need to place some ships (or have them auto-placed) before the game can start.

ragebol··on Ask HN: What are tools you have made for yourself since the advent of AI?
Made a multi-player Battlefield game for my scout group: up to 6 players set up ships like in the classic Battefield game. But you can try to hit any of the other up to 5 enemies and each team can see who hit them.

And instead of turn-based, you have to hike to/visit a physical location, fill in a code you found there to get bombs for the game. Or do a quiz and get the answers right.

Great fun so far!

ragebol··on The EU Open Source Strategy
All laudable efforts, but I'd love for my Dutch govt to actually use these broadly. With the support behind it to file down those rough edges for the benefit of all.
ragebol··on The EU Open Source Strategy
All great, but I would love EU and (national, local, ...) governments in the EU simply use the open source stuff already available.

Often there is an 'you must open source, unless you explain why not' and then there is some faff about why they really need to be buying more stuff from Microsoft (which is more and more cloud stuff and thus under the CLOUD act etc.)

Time to get rid of the 'unless' bit.
