alfla··on Show HN: Airmash – Multiplayer Missile Warfare HTML5 Game
Same here! Played it on my dad's old black and white display AST laptop :-)
alfla··on Hello, world: this is WikiTribune
We have a website in Norway that does fact checking of news and statements made by politicians etc in the media: https://www.faktisk.no/om-oss/ (only in Norwegian)

I feel that they have a really meaningful and important role in the political debate today.

alfla··on Tesla Semi
Would be interesting to know how large proportion of trucks were in the 4% largest trucking companies. If that turns out to be a large quantity, then the 96% figure no longer seems that big.
alfla··on What is backpropagation and what is it doing? [video]
I agree. Visualization is often key to understanding and identifying non-trivial issues.

Here's a tool a colleague of mine made for inline "visual debugging" for e.g. computer vision, written in c++: https://github.com/lightbits/vdb. I haven't used it myself, but when he presented it I think it made a lot of sense to have these sorts of tools for processing data in real time.

alfla··on Show HN: Tello, a simple way to manage TV shows – built with React/Redux
No problem. Keep up the good work, I would really like this to work well :-)

Cool. The design is pretty slick, the calendar is currently not working for me. Nevertheless, here are some first impressions:

- When adding shows, why do I first have to select a show and then press "add show"? It would maybe make sense if I could continue searching and add multiple shows, but right now it seems like an unnecessary extra step.

- It would be nice to see some more information about each show. Even though I might remember the title of the show, there are some shows with similar titles, so that I'm not completely sure that I've selected the right one. Just a link to the IMDB page or something would be sufficient. Or maybe just the release year.

alfla··on Why we switched from Python to Go
Could you elaborate on how ROS fits into this framework?
alfla··on Interactive Vim tutorial
Do you mean scrolling with a mouse? It might sound a bit arrogant, but there's rarely any good reason to scroll with a mouse in vim.
alfla··on Show HN: Using LDA to suggest GitHub repositories based on what you have starred
Did not work for me, I have about ~130 starred repos.
alfla··on Global warming may be occurring more slowly than previously thought: study
Original article: http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo30...

Quote from the abstract: "Hence, limiting warming to 1.5 °C is not yet a geophysical impossibility, but is likely to require delivery on strengthened pledges for 2030 followed by challengingly deep and rapid mitigation."

alfla··on Scilab – Open source software for numerical computation
I would suggest you add "Simulink" to the title, i.e. "An open-source alternative to Matlab/Simulink".
alfla··on Scilab – Open source software for numerical computation
I believe Scilab has a Simulink equivalent, whereas I do not think Octave does?

I'm a control engineer by training, and to be honest there's really no equivalent to Matlab/Simulink right now for control system design. Fortunately I'm currently working on statistics/sensor-fusion related stuff, and Python works just fine for that.

alfla··on The software routing 260,000 grocery deliveries a week
The article is quite vague on the problem formulation, other than being somewhat equivalent to the TSP, so I'm just going to speculate a bit onto how they solve it. The TSP can be formulated as an Integer Linear Program (http://examples.gurobi.com/traveling-salesman-problem/). This type of problem is very well studied, and several free and commercial problem formulation tools and solvers are available, some that scale to thousands of variables.

They also probably decouple their problem into disjoint regions before solving it, to reduce the dimensionality of the problem(s).

alfla··on I made my own VPN server in 15 minutes
I guess you risk the same issues when hosting your vpn on a cloud provider though?
