I have been using Bookstack, I like it though it is missing a few features I would love:
As heating network, they are and will be regulated like other energy suppliers: https://www.gov.uk/government/publications/energy-security-bill-factsheets/energy-security-bill-factsheet-heat-networks-regulation-and-zoning
That’s interesting, it looks like I may have a bias on that due to my scientific background.
I always said salt, of sodium chloride for NaCl. Who is using sodium for table salt? The only time I heard that associated was when saying that table salt is a source of sodium, which is true.
Most likely because the news is in English. And why would Natrium be better on an international forum?
It is Sodium in most Latin languages (despite Natrium being Latin), in Hindi and in Arabic. And Chinese has a different root. Among the 10 most spoken languages (according to Wikipedia), only Russian is using Natrium.
The cheapest ICE Dacia is 12000€. I suspect you are comparing a new car price vs a used car price, which is quite unfair.
You can get a used Dacia or a used Zoe for a bit under 10000€, which has probably less km than your car (see this one https://zoomcar.fr/dacia-spring-business-2020-33479218.html, or the numerous Zoe). Now granted these are not great cars: but it is hard to compare a 5-10 year-old ICE with an electric, simply because the electric used market is still small as these cars are new.
Now you raise a valid point on the chargers. But this is coming and that’s why no one (almost no one, I’m sure there are lunatics somewhere) wants to ban ICE right away. You ban new ones in 7 years, and this means that in 17 years a good majority of the cars will be electric. Chargers are quite quick to install, especially low power ones. There are many companies focusing on street light charging and as the number of electric cars grow, public chargers will become more available with a denser network. It’s really a chicken and egg problem - they won’t install massive amounts of chargers for them to stay unused.
Je suis curieux, tu parles de quelles voitures là ?
It’s not really major news because the report is inaccurate and they are not dying at any abnormal rate at the moment. The only news is that one website is having issues updating their data and can temporarily display misleading information.
Be careful about news on this. The data coming from satellitemap.space can be unreliable for recent data.
If you look at he work from Marco Langbroek https://twitter.com/Marco_Langbroek/status/1705562829225410697 or Jonathan McDowell, respected figures in space object tracking, these reports are inacurate.
I agree with you on proxy.
For hub I am not sure, that sounds a bit more mainstream to me, with the caveat that English is not my mother tongue. That gives a nice image that an instance is basically an access hub to a whole universe of data.
Instance are far from being simple proxies. While instances can act as proxies for other instances, the aim is to have each instances to have their own communities and be somewhat self sufficient. If you remove the federation, Lemmy (and other fediverse software) still work, it’s just that it is more difficult in that case to reach a critical mass of users.
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.
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?
Around 20-25% power consumption reduction against native resolution, that’s neat.
