@freemo It worked out okay. I struggled to keep my RF and power grounds separate, and I learned about stitching capacitors. I made a board with a 16-way splitter and a variable phase shifter on each output. Went 6 layer PWR,GND,Input,Output,GND,PWRGND. The input and output will both resemble microstrips with their adjacent GND planes.

@EVoCeO @design_RG PyCharm is great, but perhaps not easy to use. It is built from the ground up with things like virtual environments and reproducible builds in mind. If you're just getting started, I can see that being somewhat overwhelming. I would personally suggest that something like spyder might be better, for somebody getting started. It also has syntax highlighting and code completion, but will just use your default python installation and pip installs. I would also suggest that you go back to pycharm when you're thinking of starting your first serious project.

@freemo I'm learning to make multilayer PCBs with KiCAD. Never used PCB software before. Seems like I'm going to need to start making some footprints.

@freemo I'm usually an open source fan, but nothing comes close to sublime text. It is similar to atom, but its a native application and so speedy; you'll never want to touch an electron editor again.

@freemo @M0YNG Indeed, so I suppose the original post was valid. Even in academic environments I hear people say "books? I don't use books I use google" it's something that concerns me, so I suppose I jumped to make it about that.

@freemo @M0YNG Papers are generally expensive if you aren't at an academic institute and they are also not a great place to learn a new topic. I often find technical information on places like wikipedia either totally inaccessible or so simple its unusable.

Honestly I don't think I've seen anything that comes close to replacing a good textbook. The information is probably all there on the internet, but not nearly as accessible or curated.

Thanks =]

I will eventually make my dipole magnet post.

Just made a short post about how to simulate electrostatic nonuniform charge density distributions with FEniCS; that is spatially varying charge density distributions. This could be useful for simulating things like particle beams which are commonly assumed to have Gaussian (or similar) distributions. This is a small extension of a previous post about how to simulate uniform charge density distributions.

@Rovine you could use node if you've already looked at JavaScript.

@freemo works for me too now, thank you very much :)

@freemo I'm getting a gitlab 404 on video.qoto.org I'm afraid.

@mngrif nim is pretty interesting, you write something with a python-like syntax but its converted to c and compiled.

@freemo @freemo I'll sign up & upload my geometry making videos here, the instance I used originally has been down for a while now.

@Rovine well my aim isn't really to learn about blogging platforms so I wouldn't try anything too experimental, although I would consider a self hosted WordPress blog. Do you have a preferred host?

@Rovine @freemo I do this for physics and maths, if I want to learn a new subject I essentially copy a whole chapter out by hand. I often derive the results rigorously though, where books just quote an answer and I attempt some problems. I have found this to be very effective.

@freemo When I first saw this all I could think was "this is why nobody uses the divide symbol", all ambiguity disappears when it's written as a fraction.

@mycroft@mastodon.social I suppose in some areas of education its necessary, I'm coming from a physics & math background.

@mycroft@mastodon.social I wish people wouldn't use PowerPoint for teaching, I understand that its easier for teachers but I find it very unhelpful for actually learning.

@piggo Which of these features is Firefox lacking?
