I was called a few times, but the last 3 or 4 times it happened always at the exact same hour when I was putting my kid to sleep so I could not answer. And now I am not called anymore... 😥

Sorry, my autocorrect changed its into it's.

Overlay it with a map of electricity emissions and it will fit nicely with a few small exceptions (like any small country neighbouring Poland, they will have bad air regardless of their own production).

Tailscale surprisingly was the fastest, even faster than plain Wireguard, despite being userspace. But it also consumed more memory (245 MB after the iperf3 test!) and CPU.

Do we know if this is a variation due to the test protocol or Tailscale is using wireguard with specific settings to improve, slightly, its speed?

Even as a slave, the cost of a human work is magnitudes above the cost of using a pump with petrol. A slave may be able to output ~1kWh per day, that's mostly a few 10s of cents anywhere. Can you feed anyone on that?

I actually would not be surprised if SpaceX starts using Starling for one of their thrusters in the future. I'll keep the typo.

If you have fiber, it's unlikely you will benefit from something like Starling. Transfer data wirelessly through a constellation of satellites will have running costs much higher than just having a fibre. That is unless you have to dog a trench or run a fibre on mast for km for just one customer, which is where Starling starts making more sense.

Starling is for rural customers, mobile customers, and possibly an option to counter monopoly abuse by some Telco companies. But if you are in a city with fibre, then do use the fibre, that's your better option.

It's not a contradiction if you put my whole sentence. When it is really cold, a heat pump will be more expensive than a gas boiler. But over a full winter (hence "overall"), the period where it is more efficient make up for it, especially since that when it is bad, it is not that bad.

But you are right to mention the high cost of heat pumps. I would not advise anyone to get a heat pump with a goal of saving money, the return on investment is slow and rather small.

With Tailscale and other mesh VPN, by default all your machines are client and servers. If you have 3 machines A, B and C, when machine A wants to send something to B it will connect to the server that B has.

These mesh VPN have a central server that is used to help with the discovery of the members, manage ACLs, and in the case one machine is quite hidden and not direct network access can be done act as a relay. Only in that last case do the traffic go through the central server, otherwise the only thing the central server knows is that machine A requested to talk to machine B.

You still have to trust them if you want to use their server, but you can also host your own server (headscale for Tailscale). Though at this point you still need to somewhat trust Tailscale anyway since they re the ones doing the client releases. They could absolutely insert a backdoor and it would work for a while until is is discovered and would then totally ruin their reputation.

The Oxford study is really good. But I can't say the same about this article.

A COP of ~2 is not great for a heat pump, calling this a triumph is really weird. But from a journalist saying that a COP above 1 means the heat pump "creates energy", I am not sure I should have expected more.

But what's great is that this COP of 2, while bad, is not catastrophic. That's still in territory where gas boilers are more cost efficient that a heat pump, but unless you are living in a place that is consistently under -10C for several months, then a heat pump has overall lower running costs than a gas boiler. And you are starting to hit pretty northern territories with this.

What's important is also to be able to store heat during the day so that the heat pump runs at its most efficient time. But that can unfortunately coincide with the higher consumption time, so the timing needs to be adjusted properly to avoid using it during consumption peaks.

It depends on what you value. For performance and power density, nothing really beats lithium at the moment.

However, for grid-scale battery these parameters are not necessarily very important. What matters most is cost over the lifetime, and that's wher zinc batteries could be useful. They have the potential to be much cheaper than the cheapest lithium batteries.

I think that's unlikely. The nigerien force would encounter a lot of resistance, and this is likely to escalade the situation with ECOWAS and the African Union.

This is a game of chicken and the junta has very few good cards to play right now. Strategically, their only option is to wait until people are forced to accept them. But that option is extremely difficult given the current economical situation and blocus. They have almost no allies around them

They are rated for the temperatures, if you use the right duct tape. We flew one here: https://m.dpreview.com/news/7371388799/nanoavionics-captures-first-4k-resolution-satellite-selfie-in-space-with-customized-gopro

There are less guarantees regarding life time due to radiations, but they are surprisingly good on this and the one in the link still work to this day (525km orbit)

It goes much more into details than that. Math comes very fast into play (and yes, simple sums is math and many people struggle even for that unfortunately) and if you want to avoid it, you have to trust other people to do it for you. And that comes with a small or very high price, depending on how well you are able to judge them.

For example, if you want to build a fence around your house, paint your walls a new color or with a design, or sew yourself a new outfit or quilt, all of those activities require knowledge about measurement and scaling. More complicated construction projects, such as building a treehouse, require lots of mathematical problem-solving skills.

Once you’ve laid out the plans for one of these projects, you need to buy all the materials. Percentages – which are special kinds of fractions – are especially important to understand when managing money. Understanding percentages can help you budget your money and increase your net worth.

Beyond budgeting, you might find yourself using percentages when cooking a double batch of brownies, determining how much medicine to take when you’re sick or understanding the weather forecast.

One thing to keep in mind is that the websocket sync is not straightforward to set up with vaultwarden and the proxy. If you don't have it working, then your client does not necessarily sync on every change.

Maybe this is related to this, with sync not being performed by the client you were using for modification?

If you are in an enterprise environment, it is easier to sell Ubuntu - at least there is a company that can provide support for it behind. Companies want to make sure someone is on the hook to fix an issue that would be blocking to them, and this is much harder with something like Debian.

That's why Red Hat is used that much in companies, and what Canonical main revenues are coming from.

But as a selfhoster, I use Debian by default for my servers. Only if there is a very specific need for Ubuntu would I switch, and I am frankly tired of the Snap shenanigans on my desktop (thinking of migrating to PopOS or KDE Neon).

If you don't have it on your device, you can install this open source app instead: https://github.com/seemoo-lab/AirGuard

There a nice reaction from Bjorn Nyland sharing his thought about this: https://www.youtube.com/watch?v=yYSOGCrAGAw

TLDR: Tesla's software is probably confusing and Tesla should have addressed the software issue instead of trying to bury it, but overall the article seems to be confused about a lot of things and the cars are still among the best, if not the best, on the range aspect.
