I don't understand the 'never gotten usb-C' part. Modern phones have more than enough space for two connectors. So usb-C next to a micro-B charging port is no problem. After a while, almost all phone also have usb-C, most peo

I doubt there is any text that browsers have to enable those certs by default outside the EU. It could weaken protection for people in the EU, but then the way forward is to make requirements for root certs mandatory in the EU. Maybe I miss

I wonder why QWACs are less secure than DV. There is an argument why EV should be treated the same a DV I'm not buying that argument but for the moment let's accept it as true. However, now Mozilla is arguing that EV is less secur

Yes, because if you web server publicly reachable, letencrypt can be automated easily. And there is plenty of letsencrypt software that does fully automates this. A public web server is the easy part if you want to do letsencrypt.

Receiving mail is also not hard. You may have to deal with the bonus mail (spam). But that's it.

Close to none. Just a letsencrypt cert and not completely outdated ciphers is enough.

I recently updated an old MacbookPro6,2 from Yosemite to High Sierra and that was a complete disaster. Took me a huge amount of time. I think there two problems: the upgrade could not handle the way the disk was partitioned (or something el

I think you underestimate how much green hydrogen is going to cost. Yes, it would be great if green hydrogen is going to be as cheap as petrol today. No need to worry. However, that is just very unlikely. Just basic physics how much energy

People will quickly figure out what is cheaper. And that is using electricity as it is generated. Second best, if it is predictable, store electricity in batteries. Most likely a home that has enough solar panels, can store energy temporari

by phicoh 5y ago
That is unlikely because cheap hydrogen can be used to stabilize the grid. So with green hydrogen, the grid consists of cheap green energy or electricity from hydrogen. In areas with lots of solar, you can charge your car during the day and

Any FCEV is basically a hybrid EV. The obvious reason is that the fuel cell doesn't generate enough power. So you need a battery as buffer. When it comes to fossil fuel, any ICE is cheaper than FCEV based on grey hydrogen. It is very u

by phicoh 5y ago
Maybe there is the thing that hardly any hydrogen is created from non-fossil sources. Given the challenge of bringing enough green electricity online, producing enough green hydrogen for industry, it is extremely unclear how we can afford t

I wonder how this will work if they can sell the hybrid cars only in Japan. A hybrid is a good idea as long as the ICE plus associated mechanics is cheaper than the bigger battery pack you need for a BEV. However, as soon as the battery pac

There is a huge number of technical people needed for the energy transition. If everybody starts driving EVs, who installs the chargers? Who upgrades the grid? Who installs new heating systems in homes (and upgrades the electrical installat

I agree that the 386 was realitively rare. I still have one. And I remember how long it was between Intel's original announcement and 386 class becoming mainstream in PCs. However, at the time the 386 was announced I read an article ab

In 2050, you need to heat your house with something that is not fossil fuel. Realistically, that requires electrical connections to be upgraded anyhow. No problem adding a bit extra for EV. Assuming that cars are used on average 20000 km pe

One way would be to have a ban of exporting ICE cars after 2050.

According to wikipedia, China added 71.6 GW of wind power in 2020 and now has a total of 281GW. Note that 71 GW is more than the electrical power usage in Germany as a whole. And they just added that in one year. Of course, China is a very

In my opinion, we need stop burning things. When we have the technology to heat, cook, or move without burning stuff we need to use it and kill the old technologies. In theory, hydrogen fuel cell is perfectly fine. But then we reach the oth

ICE is quite horrible. The situation now is a lot better than in the past. But still compared to electric vehicals, they should be banned immediately. The other part of the equation is that the selling of ICE vehicles will happen in poor co

So you propose to power all of Germany from the North Sea area? In theory it's possible, the North Sea is big enough. But transport costs maybe become an issue.

I think the problem with storing energy in western Europe, is that you need most energy for heating in winter, when there is hardly any solar power. So any convenient daily pattern doesn't work. For wind, you can probably heat up durin

Why do you say that China does not have the land for renewables? Population denstity in China (145/km2) is less than for example Germany (232/km2).

The 286 could still run at a low enough clock speed that changing the clock frequency made sense. On the 386 that didn't work anymore, but there was an external cache. So typically, the turbo button would disable external cache. Then t

I'd say that revealing a phone number is probably worse than a matrix ID. But indeed, it would be nice if miatrix clients from element would support multiple identities. Then you can join a room with a disposable account.

While it is techically true that Germany is the biggest natural gas consumer. The difference between Germany, UK and Italy is very small. ( https://www.worldometers.info/gas/gas-consumption-by-country... ) And for exampl

The problem is that hardly anybody does a clear cost calculation of a nuclear powerplant. We know roughtly what it costs to build solar or wind. There is a bit of subsidies and commercial parties take care of the rest. In the short term we

It strikes me as weird to blame a lack of natural gas all over Europe on Germany.

As far as I know, Matrix wants to do something similar to this. They want user IDs to be public keys. A user ID can be bound to a name, but can change the name over time and keep your connections. I'd say the big problem at the moment
