I couldn't be more confused by this launch...

I had gpt-5 only on my account for the most of today, but now I'm back at previous choices (including my preferred o3).

Had gpt-5 been pulled? Or, was it only a preview?

Same here.

Do you have any links to those studies? Because the ones I've seen indicate the exact opposite. You only need 2-3 days of storage or so at most.

Tony Seba has some presentations on this topic. His argument is that renewables is getting so cheap that you can build so much that the minimum production covers all days with few exceptions. I guess that might assume some reasonable grid upgrades as well.

Marc Z Jacobsen has some fairly detailed studies for going 100% renewables. He doesn't generally assume any improvements in technology, so his estimates are conservative. I don't remember seeing anything about seasonal storage.

You may ask about colder regions. Seems like the solution there will be 1. Trash burning (getting common in Scandinavia.. you could even do it with CO2 capture as a power plant in Oslo, Norway is developing), with district heating 2. Geothermal for district heating 3. Nuclear for a bit of extra baseload (UK, Sweden and Finland are all building nuclear)

Also keep in mind that to go zero-carbon, we need to make a hell of a lot of hydrogen, ammonia, e-fuels, biofuel/oil/coal (I just read news about a Danish company starting commercial operation of a giant microwave reactor that can efficiently make bio-oil/coal from sewer sludge).

All these solutions will imply a lot of storage capacity. If you're making enormous quantities of hydrogen you're going to have buffers at both the production and consumption side. Production can probably be throttled if needed.

I'm guessing that the hydrogen power plants we already have will also be kept around to serve as backup. There's some pretty serious talk about switching the natural gas pipelines from Norway to Europe from gas to hydrogen. First making hydrogen with carbon capture and storage, then green hydrogen made with off-shore wind.

And off-shore wind is another thing that's getting more common. If you build really big off-shore wind turbines the production is very reliable.

huh, I thought Telegram was still stationed in Germany. I wonder what made them move.

chmars · 2 years ago
They have never had a domicile in Germany. In Dubai, there is basically an empty office room used as their domicile.

Hah, I think I hit a nerve there. I hear you. Overall I'm actually super happy with my Macbook. Luckily for the most part no one is forced to use the Apple eco system.

CCC for system backups. Tresorit for backing individual directories with a bit more privacy and flexibility than Dropbox.

I don't think it's self-sabotage to keep using apple software, but more a case of people not having been in the situation where things go wrong and there is nothing you can do :)

How do you use Tresorit for backup?

India suffered a 28% increase in excessive deaths from 2020-2021:

https://www.medrxiv.org/content/10.1101/2021.09.30.21264376v...

In line with many first world countries: https://ourworldindata.org/grapher/excess-deaths-cumulative-...

Notably, sub-Saharan Africa did not suffer greatly from Covid.

Sub-Saharan Africa has of course also suffered greatly from SARS-CoV-2, they just have not the means to count their cases. SARS-CoV-2 does not behave differently in Africa than in other regions of the world, especially not in low-vaccination (or even no-vaccination) countries.

«Rather than an ‹African paradox,› the far simpler explanation is that COVID-19 has affected African countries just as the virus has everywhere else, but has gone undocumented.»

https://www.bu.edu/sph/news/articles/2022/morgue-data-reveal...

In countries with a younger population, less deaths from acute COVID-19 are expected, although the number of additional direct deaths from COVID-19 is still substantial. The disease burden burden, i.e., morbidity, also remains high, maybe even more given the sub-par health infrastructure.

The advertisers pulled before any layoffs. Actually they started pulling the day before he took over.

The teams he cut are mostly silly teams. A climate team? At twitter? AI Ethics? He has to stop burning money.

He is moving twitter from ad funded (which never paid the bills) to subscription funded (which might pay the bills? $8/mo is nothing. It will certainly make bans hurt more. It will significantly help spam.)

Do you have a source for those 'silly teams'?

I also tried it and yet I cannot follow the criticism of the UI. The one thing that is bad about mastodon is that it goes like: "cool, you wanna join? Here is a hundred choiced where to join and you better make the right one."

The interface is something I actually like better than the twitter one. I can actually see content from people I follow instead of weird "engaging" content. The website definitly is more usable than e.g. Instagram, which belongs to a multinational megacorp.

There is many clients but none of them seemed nightmarishly bad. The things the clients I tried offer work and are self explainatory.

The thing is: I tried mastodon years ago for a day and did also not grok it, but this had nothing to do with the UI, and everything with the people I followed and the instance I have been on. Then it is pretty much like twitter with multiple federates servers.

According to German law, executives can be held responsible anyway …
