I guess that would be Serbia. But it is a bit pointless to have an alliance with one country.

In my opinion, social media like Facebook and Twitter were (mostly) fine before commercial interests killed them. There are plenty of reasons to connect with a group of people and have asynchronous communication. In many ways, current messa

Technically the packets don't get fragmented. It is the tunnel that fragments. For example, in the bad old days, when there was still a lot of ATM, packets would routinely get transmitted in 48 byte pieces (with a 5 byte header). Nobod

1280 is a guarantee by the IPv6 standard. If you run a VPN over a link with 1280 MTU then the VPN protocol has to have a way of fragmenting the payload (which could be using fragmentation in IPv6, but application specific is likely to work

It seems to me that in every group of people where a certain concept is often used, that concept will get a short name. You are not going to write out many times 'the chief engineer on a project'. So let's take a mostly unuse

It is a function of population density. If the density is low, you need a car. Alternatives don't work. If the density is high, cars don't work. In between there is a bit of a choice, streets that are friendly to pedestrians and b

A long time ago, Finland adopted a policy to not upset Russia. Note that Finland had a lot of trade with Russia and a complex relationship with Sweden.

So in your opinion, the slide said that with the impact of the foam it would have been very unlikely that the tile would have failed? In that case the inpretation by NASA of the slide was correct. Which is weird because slide also mentions

This issue is not that they had to ground the Shuttle until they had the data. The issue seems to be that foam was hitting the tiles with parameters outside their test database. Why didn't they go back and test with 'real world&#x

This seems like a weird argument. Russia was in a great position selling natural gas to Europe. Alternatives to Russian gas are quite a bit more expensive, so they were getting a good price. Russia could afford to limit exports to China. Wi

One thing I wonder about with these kinds of accidents: to what extend does operational experience work its way back to requirements of components. For example, if regularly pieces of foam are hitting the tiles after launch, was that part o

That points to a far more fundamental problem. Related to information processing higher up in the organisation. Just making better slides is unlikely to solve that problem.

Assuming we are talking about boring slides with just a few bullet points, then 99% of work is actually creating the (text of the) presentation. Creating boring slides can be done in a few minutes. Most time when I see a wrong and overful s

This seems to be the kind of slide made by someone without a lot of experience presenting work. The other issue is, some people really, really, don't want to speculate. In this case it seems that the person who made the slide probably

The US has a big military-industrial complex. A capable EU-army might result in a focus on weapon production in the EU. Quite a loss for US industries.

What have seen since WWII is that military attacks are extremely hard. Just about all successful missions have support of the local population in the attacked countries. Yes, the US can take over countries like Iraq or Afghanistan. And then

What does replicated mean in this context? If a room only has a matrix.org name, how do new users connect to it when matrix.org is down? Maybe it is bug, but creating local aliases doesn't seem to work in element web. (Well, creating t

I don't understand this. Older protocols don't keep any state. Many people were quite upset when old Usenet archives came online. IRC, XMPP, by default, servers don't keep any state. So why is that Discord would be required t

The server-to-server part of matrix has to be convoluted because it is poperly distributed and does encrypted group communication. Obviously, if you leave out security, you can come up much simpler protocol. Matrix has also protection again

A problem with IRC is that any individual IRC network is closed. Freenode shows how an IRC network can go rogue, and there is not much the users can do. Matrix is a bit tricky. It is mostly there, but I wonder how many matrix rooms will sur

Yes, the easiest way to get a stable grid with wind and solar is to have natural gas capacity equal to what you need from wind and solar. Gas is not used when there is wind or solar, and is very easy and quick to turn on when needed. In the

For the energy transition, it is not enough to look at the way electrictity is currently generated. All use of fossil fuel needs to go, transport, industry etc. A rough estimate is that the production of electricity needs to double. I'

If we look at CO2, which is far from the only metric, but the easiest to compare, then solar panels make up for their production in a period on months and for wind it is a period of years. Both solar and wind provide a significant net reduc

That's wrong. Germany was significantly reduced the amount of electricity from coal over the last decades. Renewables have picked up both the reduction in coal and the reduction in nuclear power.

Ignoring storage, wind and solar are now very cheap. For example, companies now pay to rent pieces of North Sea to place wind parks there.

The cost of nuclear is also insane at the moment. For example, the Netherlands has plenty of space for wind on the North Sea. But sometimes of course there is no wind. If there is no wind in the Netherlands, there is a good chance there wil

We have plenty of storage options. We can produce various chemicals, hydrogen, methane, ammonia. Production scales, storage scales. But, it is very expensive. At the same time new nuclear reactors are also very expensive. So we just don&#x2
