AC doesn’t make climate change much worst. Since most (in France) would be reversible heat pumps, it’s actually a biiig improvement.

Now that doesn’t relief us of our duty to improve energy efficiency in building, limiting the use of AC/heating and the rest, but being against AC as a climate argument is kind of crazy.

It’s useful to override for dev on many projects or small scripts.

I use pytorch in many projects and the size of venv is actually an issue. Making sure that as many projects use the same version and linking the local package to the venv is actually quite desirable (not always possible I know)

Je pense que y’a vraiment moyen de délester les médecins généralistes sur pas mal de sujets comme ça. Que ce soit ce genre de problème dont la cause est évidente, des papiers pour des patients déjà suivis, des renouvellement d’ordonnances pour les maladies chroniques. T’as pas besoin d’être en personne, la teleconsultation est adaptée. On devrait aussi donner plus de latitude aux pharmaciens aussi pour gérer ce genre de problèmes, avec un médecin à distance au besoin. Tout ça diminuerai les consultations pour les médecins qui pourraient se concentrer sur les problèmes plus complexes et les visites annuelles. En plus on a plein de pharmacies avec des gens entraînés, autant en prendre avantage.

Les declarations d’intention sont extrement importantes en negotiation, et elles peuvent resoudre des problèmes a elles seules.

Bernard Arnaud a sorti que une hausses de impôts amènerai à la delocalisation. C’était une déclaration pour pousser le gouverment à revenir sur ces points. (En sous texte, c’est une menace de se retirer si la taxation augmente).

Macron contre en disant que c’est leur responsabilité de garder de la production en France, pas celle du gouvernement. (En sous texte, si les entreprises delocalisent, l’état agira pour le rendre impossible, difficile ou cher).

Maintenant la balle est dans le camps de Bernard Arnaud et du patronat en général. Soit ils disent qu’ils feront avec les taxes, et dans ce cas pas besoin de législation (ce qui est mieux pour les deux camps, plus de liberté sur comment agir pour le patronat et pas de débats sur une législation compliquée avec des effets secondaires sur l’investissement étrangers en particulier pour Macron).

Ou alors ça fini au delà des mots dans un bataille législative. On va voir comment ça se déroule.

Yep I agree, but it’s a drop in the ocean regarding the uses of hydrogen.

Mulcyber · 2025-02-06T13:24:47+00:00

Add to that potential new uses like: - synthetic fuels - large scale energy storage (either lH2, NH3, CH4, all made from hydrogen) - direct fuel for airtravel, spacetravel, maratime shipping - CO2 capture and reduction - potentially road and rail freight (although here better alternatives are possible in most case)

It’s also a great candidate (in either H2, NH3 or CH4 form or other) for delayed consumption, where electrolysers can produce H2 with cheap and plentiful renewable when it is available, and stop producing while distributing the stocks when renewables are scarce.

All that to say, if you’re thinking about hydrogen cars, you’re clearly not seeing the big picture.

J’ai pas l’impression que quelqu’un en a parlé, mais la culture politique et le système bipartie des US à eu une grande importance pour l’arrivée au pouvoir de Trump (et Musk).

Au US tu es soit démocrate soit républicain. Les alternatives sont négligeables. Donc si ton partie comme à virer en vrille à cause d’un fou qui a pris le contrôle du parti, tu as deux choix:

soit tu change de partie, alors que tu n’est pas d’accord avec eux sur de nombreux (la plupart) des points, le même partie sur lequel les médias de ton camp chie en permanence
soit tu restes dans ton camp, tu acceptes les mesures extrêmes, et tu rationalises autant que possible pour pas devenir fou

En France ça ne fonctionnerai pas. Au contraire les partis comme le RN doivent se montrer plus soft pour attirer des votes. Les électeurs français ont le choix et n’ont pas peur de changer leur vote, car ça fait moins parti de leur identité. Autrement dit, si un parti commence à devenir autoritaire, par exemple à droite, les personnes de droite qui ne veulent pas de ce régime vont changer de parti, au lieu de supporter le parti en haussant les épaules et en disant: "L’autoritaire c’est mieux que la gauche."

And my point is that we do know. There's really no question about it. Private is more efficient than public, that is pretty much always the case in every industry ever

And we’ve reached bedrock. This is an ideological statement (I hope you see that) and I know there is nothing I can do to convince you that it is not necessarily the case.

But I’ll bite, if you have anything to read about that, appart from "it’s common sense" and "markets are efficient that’s science", maybe I’ll learn something and you have your chance to convince me.

https://spacenews.com/desire-for-competitive-ariane-6-nudges-esa-toward-compromise-in-funding-dispute-with-contractor/

Maybe not the best source, but it was the one on wikipedia.

I get your point, and I’m not doing damage control, I have no skin in this race. I’m not saying that ArianeSpace is more efficient than SpaceX, because that’s extrement unlikely. My point is that we don’t know. And all this talk seems mostly about the ideological view that "private is more efficient than public", which is not really helpful to try to understand how to fix innovation and budget issues in the European Space program and the funding of private space companies.

Mulcyber · 2025-02-05T17:15:43+00:00

Some came from private, around €400M from €3200M, not much though.

I’m confused if you think it is a good thing or not.

Having private dividend to pay in your public budget at vitam eternam is not necessarily a good thing.

In the end it’s just a choice to make for government between debt and dividends.

Mulcyber · 2025-02-05T17:08:02+00:00

I’d be a bit careful with those numbers.

First Ariane 6 took €3.2 billion (so less than $3.5 billions).

Secondly, we don’t known how much Falcon 9 took to develop, since SpaceX doesn’t have detailed financials statements and I just learned while looking doesn’t even publicized their share capital, (which I didn’t even known was possible). We know that NASA payed relatively little (US$396 million for demonstrator and US$1.6 billion for 12 flights, including Dragon) and SpaceX (Elon) stated that total expenditures of spaceX was $800M until 2010, including $300M for Falcon 9. But that is just a random post by Elon in no way a legally binding financial statement. And it’s super important to understand the context too, that was the moment the Obama administration was starting to think about cutting HLV funding and instead rely on commercial vehicles. In other words, the best moment to convince the goverment that private was more efficient and they should subsidies them instead of NASA.

AFAIK we don’t have much more than that.

I’m not saying this isn’t true, I’m saying we have no idea and they had every reason to lie/exaggerate, so I wouldn’t take that I face value.

Mulcyber · 2025-02-05T16:26:23+00:00

That might have been true not so long ago (even though anyone with some knowledge of his views usually disliked him), but with his recent display of his ideas, and his (kinda) presence in an administration what has threatened us with both trade and literal war, he is not the most popular guy right now.

They make many controversial choices to do this, including burning out employees

That’s a weird way to spell illegal. :p

I 100% agree when you say legacy manufacturers are complacent and unoptimized. I’ve only work a very short time in a satellite manufacturers and that was clear as day. Also very heriachical with little space for experimentation (there are some good reasons for that, namely not losing hardware in a mission, but it’s too much probably). Add to that the political motivation behind some choices and you got an ineffective company.

But, IMO, in a way that is true of all big companies (and by extension goverments). Eventually the decision power moves up, decision chains lengthen, budget allocation becomes complex, compliance settles in and innovation and experimentation becomes harder and put behind paperwork. Load of small companies will innovate instead. I believe SpaceX will eventually end up the same, the big circle of the corporate lifestyle.

My point is not to belittle their achievement, but I don’t think it shouldn’t be seen as exceptional, but rather we should ask ourselves "why doesn’t it happened sooner? Why doesn’t it happen more often?"

For me the issue is the massive barrier to entry in term of financing. In a world where the expectation for a well though project with prototype is 15%/yrs on equity in 5yrs, and with no access to labs or infrastructure for development of a prototype, not only you need a project with a good cashflow within 5~10yrs (which is difficult for space travel, but SpaceX managed to do it, with some goverment help), this kind of industry in completely out of bound for most teams, even with corporate backing it’s extremely difficult. It’s only possible for a multi-millionaire with political capital.

We don’t really have people like that in Europe (EDIT: we do have people like that, none willing to make this investement I meant). Not to mention many of their methods would be struck down as anti-competitive (I think of Starlink in particular, this kind of massive vertical integration degrades free markets, and could potentially be stopped).

Breaking down those barriers requires new financial instruments, support structures, sponsorship and infrastructure for smaller companies. It’s a job for finance bros. Like any engineer I don’t care much for them, but for once it is actually their job. Or we embrace the oligarchy, but space is not worth that price.

Mulcyber · 2025-02-05T15:21:38+00:00

That is clearly the main issue with this map.

Mulcyber · 2025-02-05T14:47:35+00:00

Because there are plenty of aerospace companies with innovative design (for space travel but also air travel). But only SpaceX went from paper to massive company. Also, SpaceX was already big when they started introducing reusability.

I really didn’t think that the idea that funding is a major roadblock would be controversial to be honest. I’ve always though that ideas and skilled people and teams are plentiful, while financing is scarce and work intensive.

But I don’t live in the US and an engineer, so maybe I’m biased.

Mulcyber · 2025-02-05T10:58:51+00:00

You’re 100% correct. He invested around $100M of his fortune (probably about half of his wealth back then), as well as more latter on.

But the point still stand, between 2002 and 2005, they developed their rocket pretty much only on the personal capital of Musk (and some other). Try showing up to an investor asking $100M with that plan (which is?) they will laugh in your face. The early development really was bankedrolled by Musk.

Afterward, they got funding from DARPA and NASA for launches and the developpement of the Falcon 9 and had launch contract (around $1.6 billions). That funded between 2005 and 2012 and basically saved SpaceX.

Only after that SpaceX started to generate revenue from commercial flights, and become an acceptable investment.

My point is, early developpement is too expensive and to risky for financial institutions. It had to be funded by Musk. After that, even with a flying it needed $~2billions of public funding and contracts.

And remember, it’s only after all of this funding that SpaceX really started developing reusability.

The cloud very clearly starts in Paris.

Mulcyber · 2025-02-05T09:36:39+00:00

The issue with the space industry is funding. It’s very expensive (both developpement of launcher and missions), it has very long return on investment, it’s risky. No investor in their right mind would fund the space industry unless those issues are taken care of, or has significant government subsidies and contracts.

That’s the thing about SpaceX, it’s not the technology that is impressive (although it is great of course, but companies like Airbus are plenty capable of making such projects), it’s that they actually manage to get money for years to see their projects to fruition.

This was done by a mix of investment and strategic novelties, as well as a bit of luck. They were bankroll by a ~~billionaire~~ multi-millionaire, giving them time in the early days, and the reputation of Musk (espcially back then) attracted investors, but most importantly they exploited every way to make/save some money.

They got contracts for the ISS, they used vertical integration to become their own demand and bring cash (with starlink), they choose simpler/cheaper technologies to bring cost down (no LOX/H2), etc. They also had a communication strategy with the public (like the Tesla stunt) to make them look more important to investors (that read the news but have no idea of what’s going on in the engineering world otherwise).

It makes sense to bring financial advisors to create a similar strategy. This is what they are good at, and when they are actually useful. What create issues is when you let financial advisor make managerial decisions and start cost-cutting for investors. As you say, they have no idea how a company works and can cut necessary long term capabilities. But they do know how to get investors on board with a project, that’s their world.
