fransje26··on Diesel prices in U.S. top $6 a gallon for first time
> Gemini says since Russia attacked Ukraine in 2022, so another thing to blame Putin for), now it's about 5% more expensive...

No. That's not correct. It got more expensive than gasoline since the attack on Iran.

Nice concept! Do you have any problems with mold build up?

Interesting! Is there some sort of filter system you can easily clean out, to avoid any issues?

fransje26··on Hitachi launches CO2 heat pump water heaters with solar-friendly tariff controls
From French, tarif, a table showing the amounts of payable fees, or a list of prices set for certain goods or services (1572), via Spanish tarifa, from Arabic ta'arifa, meaning notification, coming from 'arrifa, to let know.
fransje26··on What do Visa and Mastercard do? An intro to card networks
> the French CB network is 0,17 €.

No, that's not right. The CB interchange fees are 0.2% + 0.0011€ network fee.

Therefore for 1€ : 0.002 + 0.0011 = 0.0031€, not 0.23€

So you have 0.2269€ of fees coming out of left field, with someone else making a massive profit.

fransje26··on Ask HN: Are others seeing Google's reCAPTCHA rejecting Firefox users?
I also have the same issue in Firefox, Chromium and Vivaldi on Linux.

I tried searching the interweb for a cause/fix, but couldn't find anything sensible in the flood of low-quality SEO hijacking webcrap returned by multiple search engines. So I asked AI.

The claim is that it could be caused by the blocking of some DNS providers (NextDNS, Quad9, ..), and it suggested using a VPN or phone tethering.

And lo and behold, both suggestions worked, without any browser setting changes.

It's very annoying and inconvenient.

fransje26··on How bicycle coaster brakes work (2018)
> or do you also have a front brake with these?

No, not necessarily.

I've been using bikes with only rear brakes for years and years as city bikes, and never had a braking problem.

On the other hand, I've borrowed many bikes with conventional rim brakes and invariably had (serious) braking issues because they would be badly adjusted.

> Once you overlook a section of black ice, not even the nicest hydraulic disc brakes will be gentle enough.

My experience with black ice and bikes, is to unexpectedly fall flat on my face because the front wheel loses all grip. Without even getting to the point of trying to brake..

fransje26··on The Dutch are filling gas wells with cement
During my holidays this summer I met, by happenstance, an expert specialized in forecasts modeling, who has been involved in this very problematic, advising the dutch government.

He told me that the problem had been forecast and known since the early 2000s, and that basically nothing was done about it until very recently (think less than 5 years).

The problem was made worse with the privatization of the electricity network, as the incentive to invest in primary net infrastructure was very low.

So it's the classical case of a known problem with no will to invest, combined with successive governments that wash their hands saying "it's privatized, we cannot interfere". (so also with no will to invest)

The problem was foreseen, the plans were made and proposed with actionable steps and real deadlines, and nothing was done because the costs were too high.

And now the short-to-medium term prognosis is bleak, with blackouts a real possibility.

fransje26··on The Dutch are filling gas wells with cement
If it's only airco it's perhaps not too bad, as your airco usage will most often be aligned with good solar capacity, and you can compensate with solar panels. (if that's possible for you...)

For solar, starting next year, you'll get less and less money for the energy you give back to the net, so you might as well us it and store it for yourself instead of letting the energy shareholders get rich with your production.

If your unit is also to be used as heat pump, well.. ..things look bleaker globaly in the Netherlands.. Especially if more and more people step over from gas to electric. No sun + cold wave (and therefore an inefficient heat pump) is going to put some people in the cold..

A smarter network could help, if the investments were sufficient. But the problem has been known since the early 2000s, and nothing has been done about it until recently.

fransje26··on The Dutch are filling gas wells with cement
No, the problem is that the Dutch grid cannot cope with its own internal demands.

fransje26··on The Dutch are filling gas wells with cement
Yes, but contrary to the Netherlands, France has an electrical network that is able to cope much better with the demand of heat pumps, as many houses have traditionally been heated by electricity.

If anything, using more energy-efficient heat pumps might even decrease the load on the network.

From a Wikipedia comparison

- https://en.wikipedia.org/wiki/Stuttgart#Climate

- https://en.wikipedia.org/wiki/Climate_of_Budapest#Data

(I took Budapest, for the sake of generality, from [1] it is clear that there are significant variations in Hungary)

You can see that the mean temperatures from April to October are about 2 degrees higher in Budapest than in Stuttgart, which is really significant. To give you an idea, that's a lot closer to Avignon (France) [2], which is a Mediterranean climate, than to Stuttgart which is considered oceanic.

I also remember people saying that they could get 2 harvests of figs a year in Moravia (CZ), which you will not get in Germany. Moravia is not Hungary, but it's getting there, climate-wise, and it illustrates nicely the difference a few degrees (mean) make.

fransje26··on Hybrid-Electric Aicraft Engine Targeting 30% Fuel Efficiency
So, for a Dash 8-100, at 13,000 kg, disregarding drag, engine efficiency, etc, to take-off and climb to 1000m and accelerate to 150 knots (77 m/s), you will need:

- 13000 * 9.81 * 1000 = 127.5 MJ, to reach your altitude

- 0.5 * 13000 * (77)^2 = 38.5 MJ, to accelerate to your climbing speed.

Total: 127 + 38.5 = 166 MJ, or about 46.11 kWh

For a go around, re-accelerating from 1.3 * stall speed (85 knots / 44 m/s) to your climbing speed, and going to your missed approach altitude of 1000 m, you will need:

- 13000 * 9.81 * 1000 = 127.5 MJ, to reach your altitude

- 0.5 * 13000 * (77^2 - 44^2) = 26 MJ to accelerate back to your climbing speed.

Total: 127 + 26 = 153 MJ, or about 42.5 kWh

> This is the new reality for all airliners now that there are much more rigorous mandatory safety analyses in place.

That's an interesting roundabout way of saying that they were not following the certification requirements before, and that it now takes much longer for them to actually conform to the rules they should have followed in the first place.

> The 777-9 just happened to be on the edge of certification when they came along.

Yeah, killing 346 passengers due to extreme negligence will do that to you.. These pesky FAA requirements standing in the way of business..

And more generally, door blow-outs during pressurization tests and engine pylons failing are maybe not things that can be blamed on certification rigorousness..

fransje26··on Airport Simulator
Great little game! Thanks for sharing!

Just two little niggles:

- I feel like I should be able to fly over a runway without crashing in a landing/taking-off airplane. The vertical separation would allow for that.

- It would be nice to have an (optional?) zoom-out level, to have a bit more space for routing.

But a lovely little game, thanks again.

> And I was in Serbia lately [..]

With OP postulating that it is to enable corruption, and a sub-reply affirming that it is therefore the trait of a country in decay, bringing in Serbia as a counter-example is hilarious.

Serbia ranks 116th in the corruption perception index, Germany 10th. (Lower is better)
