It is kind of obvious but I think it is worth mentioning out loud regarding whether how to classify something as essential or accidental complexity is that where it ends up falling is only easy to tell in hindsight. Recently I finally reali

Maybe with polarization maintaining fiber? If at the gap they are aligned a teist will make them more perpendicular reducing mode coupling. Disclaimer: I know nothing about this field but have spent a lot of time in a dark lab surrounded by

I was refering here to playing competitively, that is, playing with the only goal of winning. Of course, it is perfectly acceptable to play for style or to manage a podium with the worst configuration or anything you fancy [ ]. However, if

Nice article! The resulting Pareto front really highlights how hard game design is. You can get millions of possible combinations but the reality is that only a handful of them will ever happen in a competitive environment.

A fantastic interactive introduction to Kalman filters can be found on the following repo: https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Pyt... It explains them from first principles and provides the intuiti

Absolutely. This is very much like the answer you would get from a politician. It's proof by word count. Q: Why do you think X is Y? A: < 10 minute exposition that doesn't address the question > ... therefore Y.

Maybe for the ladies or the men that pee sitting down, if they manage to make their way to the toilet without rolling down a flight of stairs. However, if I try to pee with one of this on my wife will not appreciate it.

One of the first things most people configure with Vim is a more convenient way to escape (ctrl+[ not withstanding) into normal mode. I don't know enough about Emacs culture, but given how prevalent Ctrl/Meta are I would expect so

Upon a bit of introspection I found that for me, such things were just ways of stroking my ego. I just find it liberating to not really care or give much thought about what my audience cares about or who they are. I write first and foremost

There is no best musician. Not just because there are a multitude of different skills that go into it, but also because nobody agrees on what weight to give to each of them or even what they are. This makes it impossible to make an absolute

At my current company we build satellites with imaging spectrometers as payload and wanted to propose building a bunch of this on our upcoming team day. I was hoping for the non-technical team to get a better feeling of what is that we are

I wrote this because I needed to calculate transformations between two cameras’ point of view and I just couldn’t find something accesible and straightforward. Hopefully somebody finds it useful.

He quotes that you need a lot of points and a fancy transformation to correct images while taking into consideration the differences in elevation within the scene. While it is true that having more points is important, the better way is to

A big part of my day job is to develop an image processing pipeline for a satellite constellation. Using SIFT or another keypoint detector is one of the ways to do georeferecing. You take a basemap and your image and match keypoints on both

This style of doing things is very common in languages with a (good) REPL, think clojure or ipython. You keep sending snippets and iterating on them until they work as intended. For that, you don't need the full context of your program

When 10s of millions of your own money are at stake and depend upon how an industry is regulated you are most definitely not the right person to call the shots on how said regulation should be implemented.

We have a fun way to describe mechanical, word for word translations in Spanish. It's called _from lost to the river_, that's the direct translation of _de perdidos al rio_, which is a saying meaning that once you have embarked on

Im assuming the polygons dont change to often so you can amortize the construction of the quadtree. Depending on your world view the implementation is trivial since Shapely, a dependency they already likely have, has an implementation of it

Rust is great but isn’t the core problem here using the wrong algorithm? It looks like this is ideally suited for a quad tree instead of a naive for loop. I would expect that to pulverise any current benchmark.
