Meson internals have nothing to do with cmake, and the syntax is not python. If you want to make that comparison, meson is more restrictive than cmake, but tends to have more functionality built-in to make up for it. bazel is more all-encom

The bits of eigen that make it slow to compile are the same bits that make it both easy to use and fast. I'm sure there are improvements that could be made, but ultimately eigen is big and slow to compile for a reason.

Unfortunately our example isn't representative, and avoids a lot of things that make eigen slow to work with. Parsing the header file will take a constant time, but template expansion etc. can take a long time if you have more code. Tr

In the smaller ones, the planar transformer takes up most of the board area, so there's no benefit to assembling two different PCBs. The larger DC-DC converters are not as cost sensitive as a raspberry pi product; they tend to be used

That's not a logical reason. Rules in society are supposed to exist to the benefit of everyone. We can have a discussion about whether this particular rule really does benefit everyone, but clearly the ones that do should be respected,

Do you (or anyone else with the same claim) have a citation for this? I've spent some time reverse-engineering the echo microphone board, and while there is an interlock that prevents recording while the red mute button is lit (just th

It looks like there's plenty of seperation to me. Three things cross the boundary: The main controller has an isolated primary/secondary side, so it's fine for it to bridge. According to the datasheet it's got >4kV of

Yes, but only in one direction. If you low-pass filter a raster scan signal, then the image is blurred horizontally, but retains its vertical resolution. Vertical filtering can be implemented in analogue circuitry using line delays (this wa

This is really cool. When I first saw this, I re-did the 3D reconstruction as a bundle-adjustment problem, which resulted in this model: http://misc.tomn.co.uk/lightning/out.gif To do this, I found point correspondence

I deal with this shape of problem quite a bit. After using scons and make in the past I recently tried using ninja, and it really works well. Specifically, a python configure script using the ninja_syntax.py module. This seems like it'

Ah yes, only supporting constraints on the parameters can be annoying if your problem requires that.

I'm not sure I agree. I use one phone, with many apps, so it's helpful if the common parts of all the apps I use behave in the same way. For example, how do I get to the preferences for this app? Via a hamburger menu on the left,

I think it's just a logical and clear place to set a benchmark -- you can use as much safety equipment as you like to keep yourself safe, as long as you don't use it to help you to get to the top. Historically, climbing safety equ
