Ok, I’ll look into that then. Thanks.

Going opt-in instead of opt-out does not change the fact that I would still have to toggle the features manually. To be more specific, my use case is that I have a program to control cameras in my lab. But not all computers have the libraries for all cameras. So, every supported library can be enable/disable using a feature But the program being still in active development, I am frequently using cargo run, cargo check, cargo install, on different computers with different libraries installed. What would be convenient would be to have a configuration file on each computer, specifying that we will build only for PCO camera on this computer, only for Photometrics camera on this one, only Ximea and PCO on this one, instead of having to remember to toggle the relevant features every time. A shell script is not very convenient because I use different commands, run, check, install etc.

This would look like it would be what I am looking for, but the documentation of the configuration file does not mention features.

Thank you very much for your reply. I have tried the approach you explain in your blog post, and it works. Your blog post is useful and clearly written !

At equilibrium, I’d say yes.

I think I once read that when the metric system was first defined during the French Revolution, they also tried to use a decimal system for time, but that was quickly abandoned.

Fascinating. I heard something similar with particle pollution in big cities.

Keep in mind that superconductors have a critical current below which you have to be if you want to stay in the superconductive states. So for a superconductor to be useful for energy transport, this current has to not be tiny. I haven’t had the time to read their paper so I don’t know the value of the critical current. Also if for some reason the current suddenly goes beyond the critical current, the wire will heat suddenly, with possible damage…

My understanding is that they also need low thermal noise to ensure pure states. They cool much below the superconduction threshold temperature (eg typically 20 mK). So I am not sure that this would be useful for quantum computers at the moment. Magnetic field productions such as that in MRI requires high current, so that depends on the maximum current that this material can sustain before that breaks superconductivity. So it could perhaps turn out useful or totally useless. Hard to say at the moment.

I like the Password for Nextcloud app. I self-host mine, but I think there might be Nextcloud instances that you can access. It is encrypted, and has an app for smartphones.

Yes ! This would also be useful on Mastodon.

Do we know that this is the one and only domain that they will use when and if they actually enable federation ?

How do you forward Whatsapp to matrix? Is it two-way?

Very interesting read. Thanks for sharing. I’m curious: have you considered [matrix] nowadays?

I am a scientist myself, and I know what the HCERES says about his institute, and also that his institute no longer had support of the CNRS, which is telling considering that the CNRS only very rarely make such moves, as well as editors no longer accepting his papers leading him to create his own self serving journals. My issues with him are his lack of scientific rigor and lack of scientific ethics. Unfortunately, he’s staining the community as a whole, even though he lost support of several scientific institutions long before the Covid.

This guy is a shame for us all, French academics… sorry World, please know we’re not all frauds….

You can use a third hand, typically like this: https://befr.rs-online.com/web/p/soldering-accessories/1466439

From my limited experience, make sure the things you want to solder are mechanically held together. And heat the pieces you want to solder, and use them to melt the tin. Never melt the tin directly on the iron.

The not so tech savvy family members have trouble with e2e though. They always have problems with device somehow not properly authorized, and some encrypted rooms accessible from the computer but not from the phone. I usually solve it for them regularly, but they still can’t do it by themselves. So I prefer to keep the rooms unencrypted (we are not sharing state secrets anyway), but self-hosted (I don’t want to give away family pictures to big tech companies).

I’ve never bothered to try alternatives to Element. Are they worth trying ?
