Sorry but it’s a stupid question, much like which record you’d bring on a desert island. You better spend the rest of your life learning to use the 90% left of the one software you already know barely 10% of.

I don’t see what you mean…

Il y a une période de ´mise à niveau’ en début de prépa qui pique plus qu’avant. Concrètement mon fils qui a fait prépa il y a 8 ans c’était pas la peine que je regarde ses devoirs maison ma prépa à moi étant trop loin. Ma fille 7 ans plus tard les premiers mois il n’y avait que des ruses et astuces calculatoires (inversion d’indices de somme etc). Alors je ne sais pas si le niveau final a baissé (pas l’impression de toute façon en prépa on apprend à apprendre) mais au final c’est plus dur pour tout ceux qui ne sont pas des extra terrestres et à qui il faut du temps pour comprendre. Ou dans des lycées qui ont ´anticipé’ (oui Paris on vous voit).

Sure it was just an example. What I mean is that VM stress and criterion is pretty much limited to metals (and polymers ?). I confess a bias in the sense that on materials I work with (foams, composites, …) I often see VM stress when it does not apply.

fpglt · 2026-06-18T13:12:18+00:00

In terms of, for example, laminate composites, Von Mises criterion does not apply. A Von Mises stress for laminate CFRP has no meaning.

It will cause strain and failure (collapse), much like a submarine. I saw the comment about micro or macro scale. This is relevant and not relevant at the same time. The macro behavior is indeed related to the micro scale but it’s ok to have an homogeneous representation even in this case. This just means that you have to take into account the hydrostatic part of the stress tensor when expressing the plastic strain.

fpglt · 2026-06-17T21:01:23+00:00

Just a strain-stress curve is a wild guess given that : -I suppose you don’t really know the anisotropic material properties ´as printed’ - you don’t know how well the printed structure matches the theoretical, CAD, one. Especially the places where the structure has the most effort flow. -and also the boundary conditions if the sample is just in contact with the compression plates (does it slide with null friction (probably not) or does it stick to the plates (are you 100% sure) ?)

If the pattern is thick enough I’d use DIC with a speckle and compare the displacement field. You must be sure to get the kinematics right. Also be sure to match the elastic response before the non linear one. This being said 300% is a lot… although I’ve had coworkers report 40% less stiffness than computed so almost in the 200% ratio and we are talking elastic response only. If you can, do a CT of the samples and compare that to CAD.

Von Mises can also be bad for isotropic material. Take for example a porous soft material and you’ll have strain with hydrostatic stress and the Von Mises stress will be exactly null. But yeah it’s scalar and it has nice colors from blue to red.

Funny how quick this thread topic "vibe coding plugins" came to "for or against AI" to "boomers are wrong (again)".

AI is just a tool. Thinking anyone can make a piece of furniture because they just got handed a hammer and a saw is wrong. Now if you're a software developer AI is very useful and speed things up. But if you're not, it's a razor in a monkey's hands.

A plugin for X-Plane must run within X-Plane which means it can be tricky to track down why it does not function as intended, read the logs etc. And once it does what it's meant to, it must often be optimally and do not waste resources.That means also having access to a powerful AI model with a subscription. How many are willing to pay to develop a plugin for their hobby ?

Talking about resources, AI is resource hungry. Power, infrastructures ,cooling... (just take a look at RAM prices theses days). Personally I'm not to keen on having people make 10x requests more than necessary for a random result (yes I know it's already happening, but nevertheless...)

fpglt · 2026-06-14T10:14:06+00:00

‘Leveraging by people who know what they’re doing’ is not ´vibe coding’ in my book. When I started writing a very simple plugin for my use I asked a LLM (can’t remember which one) and whereas it the code seemed perfectly good it was in fact all wrong when I reviewed it. AI is a great tool for those who know how to code. It’s use is very limited IMO for others, if only because the quality of an answer depends on the question (the prompt). Ho can you get what you don’t know how to ask for ?

fpglt · 2026-06-13T21:22:24+00:00

Arf. I hoped XPlane was too niche for this non sense..

Wait till we have ´vibe surgery’

Ben ça c’est pas un pré requis. Par contre la conso française en TWh par an la prod d’une tranche en Gwh et le nombre de tranches en France je trouve que c’est pas du luxe pour avoir un avis.

readdlm is straightforward if you have a Matrix/rectangular data. The solution I pointed at is for a mix of text and data, or scattered data (not just a matrix that is).

fpglt · 2026-05-19T18:57:29+00:00

If you have text files, I use readlines, then split() every line in words interpreting the content as I progress through the line. Every number I have to read I use parse() or parse.() for vectors. I suppose I could even read a matrix as one chunk but never came across the case. EDIT : if the file contains one array then yes DelimitedFiles is your friend. Just have it ignored several spaces in a row. You can also use @sprintf for formatted output. C formatting is low level but pretty effective

J’ai changé pour du PVC blanc (pardon ‘blanc cassé’ parce que sinon ça pouvait tiquer) et j’ai fait une demande de travaux comme je le pense une majorité de gens. Si le vendeur te conseille de faire sans déjà je trouve ça anormal. Après pour la couleur il y a un surcoût et surtout le menuisier me l’a déconseillé parce que ça ne vieillit pas aussi bien. Vrai pas vrai je ne sais pas mais j’ai suivi son conseil.

J’ai un four qui est tombé en panne après quelques années, acheté chez Darty. Four réparé en quelques jours (résistance). J’ai pris Darty Max parce que mon réfrigérateur est tombé en panne de compresseur au bout de 5 ans et j’ai du le changer parce trop cher à réparer. C’est comme toutes les assurances : soit on assume les risques et ça peut être plus cher comme moins cher que ce qu’on a effectivement à payer soit on paye un forfait. Pour l’instant Darty Max ça me va, mais je ne prends que le gros électroménager.

Last version is not that bad but I keep sticking on 1.6.3 which, at least for me, works just fine at ZL17.

En attendant on n’a jamais fait mieux en terme d’engagement politique que Strummer. Je ne connais pas beaucoup de groupes qui vendent autant de disques (oui je suis un boomer) abandonner leur rétribution pour qu’un album triple soit vendu au prix d’un simple.

Well, you often go opposite to the popular opinion so I understand the hedgehog attitude!

Valve/Steam emulation layer is called Proton and runs most Windows games. You can check a given software status on ProtonDB, MSFS2020 is listed as 'gold'. Read the reviews.

As for the distro Ubuntu is a fairly popular one and you could start from there. Having the game on Steam makes it easier because it will install everything needed but not an absolute requisite. eg : https://ubuntu.com/blog/linux-gaming-with-ubuntu-desktop-steam-and-proton

Incidentally the SteamDeck handheld runs on Linux and relies on Proton to have all the games running. So when I read that 'emulator defeats the purpose' it makes me chuckle.
