I have been using Bookstack, I like it though it is missing a few features I would love:

• you cannot insert a video in it
• there is no possibility to comment on a particular text
• the permissions management is only done with roles. That’s fine generally but I wanted to be able to share a specific page with a specific user, and for that I had to basically create a dedicated role for this use.

I, too, have children at home.

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?

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.

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).

This is in line with all the MOND theories. The main problem with MOND theories is that so far we have not found one that would explain things better than dark matter. But this analysis shows that there are some observations were dark matter seems to break while MOND holds up better. This is quite interesting!

One caveat with MOND is that we have to be careful about overfitting the data. You could very well elaborate a very complex model that fits all the observations, but at that point you are basically back to an empirical model.

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

I don’t know if there is any specific utilities for that. You can always export your settings and reimplement them in lldap: this should be doable with a python script.

I never really understand why LDAP was so complicated. There must be needs in big setups that I am aware of but strangely I always found it not intuitive.

Yes, same for me. On android DAVx5 is perfect, and on MacOS, iOS there is native support. For Linux and Windows, your mileage may vary (fairly easy on Linux but very different variations and some require additional software).

It supports a proper sync (my wife’s shared events do show up on my phone and I can modify them there) and the address book is specific to each user by default, but you can create shared address books as well. Again, that is synced two ways.

For LDAP, by default nextcloud only reads it. But you can enable LDAP writing as well.
