Flight today is a 777 after a pretty decent stretch of mainly flying 787's and it's really wild how thin the body of the 787 is and how big its windows are.

I was and still am pretty okay at Afrikaans especially given that I barely ever use it but my vocabulary is absolutely getting cannibalized by Czech.

I love how in disney cartoons when a prince is like "father I have met a mysterious forest woman and she is the love of my life and I cannot possibly marry who you wish me to" the king is always like "No!!!!! you can't fall in love with a forest woman!!!!!! you must marry a princess!!!!!" instead of what a king would have said in real life, which is "why are you telling me about the forest woman. this has no impact whatsoever on your marriage to the princess. we all have a forest woman. it's 1183 and we're barbarians"

rescinding most of my previous opinion that kickstart is good. Kickstart is okay but the only option you have for templating is to run a shell script at the top of the file in your %pre and then write a bunch of kickstart instructions to a text file that you can then %include later. AutoYaST lets you run Jinja templates! So handy, so much less room for error. You can access a whole bunch of native ruby datastructures inside YaST instead of having to grep and sed command output for everything.

I guess that is part of why kickstart is popular though, you can implement it without having to convert your distribution into a ruby object.

Saw @faetoothofficial at Casbah in San Diego tonight, absolutely killer set. I tried to get some decent photos but somehow these smeared hazy pictures feel like they capture the vibe better

Do you have thoughts/opinions on implicit modeling for CAD? I know Fusion 360 has an implementation of it, but their add-on packages aren't cheap so I haven't gotten to play with it.

I haven't touched much in the way of implicit modelling, the closest I've probably got is some higher tier programmatic primitives based modelling with things like openSCAD or the much weirder ImplicitCAD that one of my acquaintances was working on.

It definitely seems useful! Being able to define and merge shapes with all sorts of interesting boundary-based effects is a great idea, it's like putting shaders into your modelling system to create fillets. If you want to define a complex space-filling load-aware mesh for 3D-printing the inside of a wing or something you definitely want a tool like this instead of doing it by hand.

it turns out SUMA is not really designed for clustered VM deployments which. okay fine I understand this the thing you're meant to do with SUMA is run five hundred retail kiosks or six IBM mainframes running SAP, but still, annoying.

Moving to OpenNebula which seems neat but doesn't have repos for suse and at the moment I do not feel like repackaging all of OpenNebula on my own.

This is especially a shame because I'll have to migrate my autoyast and Saltstack to Kickstart and Ansible. I will admit that Kickstart is nicer than autoyast but I actually really like Salt.

fine I'll use a redhat derivative

Mood, also jealous about NX, I have really wanted to just try it, just once.

Arguably the thing to improve these days is geometry kernels, almost every major parametric CAD package uses parasolid behind the scenes (except AutoDesk I think?). It's a huge slowdown for big assemblies and complex operations because it's really old and doesn't take good advantage of modern hardware.

There are several companies working on GPU accelerated geometry kernels, the two I know offhand are kittycad and dyndrite, but both of them currently only support direct modelling. Kittycad's main product appears to be a billing model.

I. Look I don't know what the primitives modelling for engineering world looks like. It's definitely real, surely some of the weird blobby shapes I see are smushed out of vertices rather than formed from bezier curves but I still find it hard to believe. Purportedly real engineers use BRL-CAD regularly and I have seen very impressive engineering models of military hardware made in BRL-CAD but I still don't know how you could live like this. How do you convert this pile of cubes into a manufacturing plan? Is this all just for simulation. I genuinely do not know.

KittyCAD has a pitch which is that you can store your models in source control but like. Diffs on your series of operations are not diffs on your models, it's useful but there is something of a reason why OnShape's rollback system is a weird two-tier thing. It's very difficult to talk about "diffs" with 3D models and I feel like all the parts I see in direct-modelling demos are like. Toys? They're so simple. This is what Dyndrite has on their homepage as an example of their product? This?

FreeCAD opens with a model of a radial engine! This is the shit!

Are there any primitives or operations you wished parametric CAD software had?

This is tricky, because parametric CAD is what I learned to design on so its feature set feels "natural".

I don't really think so! Most of the obvious innovations are already covered, SolidWorks can take a model back and forth between parametric and primitives modelling in its own weird way, Inventor has really great design for manufacture features, from what I've seen SolidEdge has done some clever stuff with the solver to help you design parts that are customizable as you go down the chain. Who knows what's going on in NX these days, not me. There's definitely some holes in the sense of individual packages lacking features, but almost anything you can ask has been implemented somewhere, by someone.

Good quality design for manufacture tools really do help, I remember doing sheet metal stuff in Inventor back before they cut off free Inventor access and being able to see your generated sheet and bend allowances so clearly was great, and now even OnShape has pretty solid design helpers.

A thing small shops and hobbyists would probably like is better handling of point clouds and photogrammetry for matching parts, since you're much more likely to be working with parts and projects where you didn't do all the design, I've spent many hours trying to accurately model a mating feature, but even that's like. Pretty good these days, importing 3D scans into an editor is pretty standard and the good CAD packages will even let you pick up holes and clean up point clouds directly from the scan.

I'm not that much of a mech eng, and never really was, my CAD is mostly self taught for simple tasks, real mechanical designers no doubt have better opinions on this, @literallymechanical probably has thoughts on T-splines.
