You cannot really hide it. The launch has to be public to warn airplanes and ships so they can avoid the area. And once the launch is public, such a failure is quite evident to anyone who was interested in following it, so you might has well publish the news instead of trying to hide the unhidable.

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.

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.

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

How were you even able to cross the parking lot? It's not like the Toyota Camry can ever return the salute so would you basically become stuck in a salute forever?

I'll provide an ELI5, though if you actually want to use it you'll have to go beyond ELI5.

You contact a web service via a combination of IP address and port. For the sake of simplicity, we can assume that domain name is equivalent to IP address. You can then compare domain name/port with street name/street number: you need both to actually find someone. By default, some street numbers are really standard, like 443 is for regular encrypted connection. But you can have any service on any street number, it's just less nice and less standard. This is usually done on closed networks.

Now what happens if you have a lot of services and you want all of them reachable at address 443? Well basically you are now in the same situation as a business building with a lobby. Whenever you want to contact a service, you go to 443, ask the reception what floor they are in, and they will direct you there. The reception desk is your proxy: just making sure you talk to the right people.

I don't understand your graph. It says you are measuring gigabit/sec but shouldn't the true performance rating be gigabeans/sec for a Lemmy instance?

[-] marsokod@lemmy.world 30 points 1 year ago

The world produces 15Mt of beans every year. The average shit post with beans has 700g of beans in it. This means Lemy can scale to around 22 billions shitposts/year. We have some margin.

Before the API pricing change, the Reddit app could be considered an internal hobby project made by a handful of employees on their spare time.

Now that this one is mandatory, it can be rated for what it is.

The cap was reduced to 30p/kWh for electricity and 8p/kWh for gas. If you are not on a smart meter, you should submit a new reading as soon as possible to make sure your costs are computed as accurately as possible.

This is a shameless inspiration from this reddit post.

Hello everyone, I would need some advice on my setup.

I had an ISP with basic DSL 60/20Mbps and I was hosting my services at home with SWAG as a main proxy, opening the ports. I ordered 2 days ago a plan with a new ISP for a 1Gbps line, that offered port forwarding as well. The installation was done today and it turns out they retired the port forwarding on my offer yesterday.

I can see potentially 3 choices:

  1. stay with the old ISP and the slow-ish line. My main issue was the uplink speed that made off-site backup a pain
  2. go with the new ISP but order the higher speed plan that is £25/month more expensive, and without a proper guarantee that they will keep offering the port forwarding
  3. use the non-port forwarding option, but rent a small VPS that would act as a front-end (through zerotier/tailscale/direct wireguard), paying a small latency cost when accessing remotely.

I am not fully sure about the pros and cons of the different ways on the last option. I would be kin on keeping my home server fully capable, the point of me self-hosting being to cope with temporary disconnection at home. But then you can either have an IP table routing in the VPS to forward everything on the used port, or have another nginx proxy there to redirect everything. And I am not fully sure VPS providers are generally OK with this kind of use.

Has anyone got a similar setup to option 3 and would have some advices?

Edit 1: Thanks a lot for your comments everyone!

I got a small VPS (not the cheapest one yet) and setup a wireguard tunnel following this principle and it seems to be working so far. I'll monitor a bit the situation as I have 14 days to cancel my plan. I'll also see how it works for gitea running in docker in the NAT and ssh forwarding, I suspect this will be a fun endeavour.

I decided to avoid using cloudflare tunnel. And I am avoiding using a nginx proxy at the moment as I would need to ensure the certificates are properly synced between the two (or maybe letsencrypt allows you to have two certificates for the same domain?)

Some exceptions seems to be accepted as long as it involves Wales and France (Wales being Pays de Galles in French).
