We did use actual data from existing lines to measure the gap between our models and reality. We were +/- 5% accurate.

Ahoi! Participated to the development of a simulation tool for that purpose. Many factors need to be taken into account: - The gradients of the track - How agressively you want to …

What else is new? This was already well known among grad students in the late 90s. We even knew there was some kind of hierarchy, with one of the student acting as «political offic…

Unrelated question: how did you manage tabular data in git? It’s always a struggle to diff and merge changes.

I will just chime in to mention Draftable ( https://www.draftable.com/compare ). It really works well. It’s not so easy to have a visually comfortable diff of two PDFs.

Well. First, the goal is precisely to remove wayside balises and replace them with gnss for resetting of the absolute loc. You can parse the last section of this: https://www.ct5we…

I cannot agree more with the author’s point of view. As an illustration, many people want to use GPS for the safe positioning of trains in the European Train Control Systems. This …

I concur. I broke my wrist.

This correct. Power lines wear induced by pantographs is the limiting factor for TGV top speed. The engineer that can solve this problem will allow top speeds in the range of 400/5…

There is something very wrong going on in Germany AND France where, despite the nice speeches, investment in railway infrastructure is being run into the ground. If nothing changes…

You have to live in a world where there is no Netflix and no Disney/Pixar yet. Where the standard for mass-media japanimation is Dragon Ball Z. People had to wait for each episode …

Smart and productive people are happiest when they are free to do whatever they feel is worthy of their time and attention. One of the key to their productivity is that they don’t …

The behaviour described in the article makes me think of a goal-oriented AI. It does not require a lot of complexity and can exhibit very advanced and quite surprising behaviour.

Dude. TI-81 was my high school calculator. I got pretty famous at some point for managing to squeeze into it a decent RPG with monsters, health points and some story line. Other ge…

Negative in my case. It’s functioning properly.

The point seems missed to me. Like any serious collaborative undertaking (movies, buildings, complex systems development, scientific collaborations, etc), successful software needs…
