I, too, have children at home.
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.
Defense money is not lost, it pays people within your country. And you can even decide whether it goes to big corps or small companies.
More accurate data here: https://planet4589.org/space/con/star/stats.html
Total down over the past 5 years is 355 over 5200 launched. And definitely not 50-100 satellites were lost in a week.
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.
Sorry, my autocorrect changed its into it’s.
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?
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.
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
Around 20-25% power consumption reduction against native resolution, that’s neat.
