  • Nuclear plants consist mainly of a shitton of concrete (and only the best sort is good enough). The production of that concrete causes a terrible amount of carbon emissions upfront.

    Actually, if you compare them to solar or wind at equivalent service, it’s not that straightforward:

    Renewables installed capacity is nowhere close to their actual production, nuclear can produce its nominal capacity in a very steady way.

    Wind turbines also need a lot of concrete, and much more metal for equivalent output. Solar panels need a lot of metals.

    Renewables need a backup source to manage their intermittency. It’s most often batteries and fossil plants these days. I don’t think I need to comment on fossil plants, but batteries production also has a very significant carbon emission budget, and is most often not included in comparisons. Besides, you need to charge the batteries, that’s even more capacity required to get on par with the nuclear plant.

    With all of these in consideration, IPCC includes nuclear power along with solar and wind as a way to reduce energy emissions.





  • Inflation reduces the value of money at the bank: the money saved as well as the money borrowed.

    In an ideal world, wages are indexed on inflation (way of calculating inflation in this context can be discussed), and inflation is kept above present targets levels (central banks try to keep it at 2% these days).

    That makes your debts easier to reimburse, and limits returns on savings. Have you ever noticed that people who keep talking about the “value of work” actually push for low wages and no or low taxes on capital gains, so actually wants the capital to make more money than work?

    A low inflation allows big money to hoard more and more. Higher inflation means money that’s not actively contributing to the economy will lose its value over time, and that’s exactly what you, at the bottom of the ladder, want (and considering top of the ladder is hundreds of billions of $, ever 6 figures employees are bottom of the ladder).

    Too high inflation leads to an uncontrolled spiral. Deflation is also very bad (no investment will ever happen if your money just appreciate by doing nothing). But the 2% target is not to protect you. It’s made for money to make more money.

    But about the link between wages and inflation: what we have today is a situation where we let cost of life dramatically outpace wage growth. So where did the inflation come from? Profits! That needs to be rebalanced.

    From 1945 to the early 80’s (before the €), France and some other countries minmum wages were indexed on inflation. If doing so would instantly crash an economy, we would have noticed…



  • All bills targeting your freedom are labelled “child porn” or “terrorism”.

    After terrorists attack in France, state of emergency was declared, special powers to restrainesuspicious powers at home. We MUST protect people frometerrorists, right? If you’re against that, which side are you on? Very first usage of the power: restrain non-violent eco-activists to their home so that they don’t disturb the COP.

    That pattern repeats over and over. They’re counting on you being sensitive to “child porn”, I bet you the initial list will include “eco-terrorists” sites (label used on anyone attending a climate protest they tried to prevent), political activists sites (you try to be anonymous on Internet? That’s SO suspicious!).

    I’m sorry for what happened to you, but ri seriously doubt this bill is really intended to prevent that.


  • I wouldn’t set expectations too high though: for the retirement bill, there were many protests, millions of people in the streets, all surveys showing a very strong reject by the people, and the reaction was basically: “I got elected, I do whatever the f**k I want!”.

    Short of a revolution, nothing can change their mind. I’d rather push other parties to include this in their program for the next elections: repel this absurdity.

    Could we define a trade-off system? Classic broadcasting can take way too long to send out a large catalog. Streaming is, as you say, a heavy resources consuming system.

    So how about a combo of a box or a software that can follow a broadcast N times faster than human, and broadcast N movies/series episodes a day? The application let you pick what you’d like to get on your box/app, and then it’s like classic video recording, but on steroids.

    It would be like live-streaming, but at 2, 3, 10 times the normal speed. No human needs to follow that.

    Of course, you still have the issue of glitches, communication interruption, but we’ve dealt with those for years, and there are certainly ways to indeed stream the missing parts, or use rediffusion.

    You read it first here. I’m off to file for a patent and make billions (or not…)




  • There is pretty much nothing done in Matrix that couldn’t be done with XMPP. But XMPP suffers from multiple issues:

    • The protocol is very well controlled, but the downside is it takes forever to have any extension approved, leaving sometimes features you would want fast in limbo for months, years, and clients/servers dev waiting for the extension to be finalized. The worst example is probably when Google dropped a group video implementation for XMPP in 2005 on the table, (at the time, Google messenging system was using XMPP) with source code, free license and everything. They would just have to take it and use it. Version 1.0 of the protocol extension was released… in 2009! Meanwhile, many clients were just “waiting” for the protocol before starting implementing anything. When the protocol was finalized, XMPP’s world could congratulate itself for being 3-4 years late on every other communication system. This story repeated recently with an encryption extension.
    • There are many clients project, most of them are carried by 1 or 2 devs, each of them almost single platform.
    • As XMPP is “older”, it doesn’t benefit from any buzz effect, and some of the “waiting for features” have worn out many adopters.

    As it was said in another comment, there is a company and some investors behind Matrix, and with that:

    • Protocol can change as fast as they need to implement a new feature. Worst case it is updated again later
    • Having much more resources, they could develop a true multi-platform client with a quite consistent interface. That eases a lot the adoption by non-technical users.
    • Being the new thing and with a bit of marketing, they had a buzz, and that leaded to more servers and more clients developed, though they all have to follow the company’s train.

    Now, from a self-hosting point of view, Matrix has a huge flaw: rooms are entirely copied and synced on all servers from which a user participates. It takes only 1.

    For example: if any of your users join a room with 10k users exchanging thousands of messages per day, your humble server will synchronize the whole flow in a local copy. There is not a chance a small server can take that kind of load. Last time I checked where they were for solutions (it was years ago, might be different today), the proposals were:

    • Option for admins to prevent users from joining room bigger than xxx ?
    • Wait for a new server implementation that’s lighter than the mainstream one? (still not released in prod to date, and won’t really solve the problem)

    And for some positive points about XMPP:

    • It proved its scalability. Whatsapp started as an XMPP server/client with no federation (don’t know how far they drifted from the base protocol now, though)
    • It is extremely versatile. Right now, there are 2 leading project that include blogging/microblogging features and more

    https://movim.eu/

    https://libervia.org/

    The last has microblogging, events, forum, ticket management, file sharing features, etc… Still needs a lot of love but it shows the potential of the protocol.

    There are other projects using XMPP for whole different things (IoT, …)
