a bit of time travelling while swimming in Germany is also possible in Munich https://www.muenchen.de/en/culture-leisure/mullersches-volks...

I guess Russia also wants to see what happens in winter when gas resources will be important on several fronts ?

what is the price of a single chip ?
depth of object is impressive - coul make an interesting documentary
started to feel changes in sleep patterns at the end of my 30ies as well... from what i know my eating patterns did not change over the past 15-20 years so much. what are scientific papers on the relation between sleep and nutrition? might be interesting to learn more on this for the future.
Re:A list of useful books for game AI programming (2014) on Wednesday January 02, 2019 @04:32PM (#18810451)
a very useful list, not only for AI game programming
would be nice to see some numbers on chip area of occupied by memory

nice list... wondering what EU unis have to offer in this context

are there any EU equivalents?

Interesting US only is at 3rd (probably less than 15% in total ... )
Re:Show HN: Alan – a low-code application platform on Monday October 08, 2018 @11:13AM (#18168164)
instead of "low-code" maybe "meta-level" or "super-level" programming ... :)
Re:Ask HN: Who was Joseph Fourier? on Thursday September 20, 2018 @04:18PM (#18035138)
thanks, i see... i read about travels to Egypt, and then curiosity on heat transport. back in that time, heat was understood differently than today, but interesting to see how the fluctuations in temperature of day/night of month/year follow a bit of sinusoidal pattern indeed. do you recall what those basic heat equations were back in that time, and why it was different from theories back then? just in case you have some more time to write on this.... thanks!

Ask HN: Who was Joseph Fourier?

Of course, Wikipedia tells us Joseph Fourier lived 1768 until 1830, but what I don't understand is how could he invent the tools that are so important in digital signal processing today?

Re:Gallery of programming UIs on Tuesday March 20, 2018 @06:48AM (#16627354)
right, what did Linus Torvalds use? Emacs or Vim?
interesting project - might be interesting to see a kind of org chart of different parlaments (eu, uk, us). esp eu is confusing with its commissions and parlament and presidents of all.
Re:Aziz V. Trump: CrowdJustice Launches in the US on Tuesday January 31, 2017 @10:45AM (#13531494)
just in general it would be interesting to see a collection of law suits that the billionaire president lost. probably not much of this public (and most processes might have ended with some kind of settlements)
Re:mJS – A new approach to embedded scripting on Wednesday January 25, 2017 @04:20PM (#13486233)
a nice graphic on the layers of an embedded software is this: http://www.limifrog.io/wordpress/wp-content/uploads/2015/07/... - getting the toolchain running to blink a LED takes some efforts. With scripting, you could save time in the context of prototyping a connected experience (networking, hardware, network protocols)
Re:Stepping into math: Open-sourcing our step-by-step solver on Thursday January 19, 2017 @12:08PM (#13437342)
that looks interesting! it engages a lot of senses, trying now to google for something like that on amazon, but maybe i can print those myself with a 3d printer. or, maybe someone has open sourced a design for those cubicles already?

without training, our brains confuses numbers easily from my experience. my niece is learning multiplication tables right now, and she confuses 8 * 7 = 56. we tried to teach her these numbers with a story, or a shortcut, e.g. 5 6 7 8 . see the groups 56 and 7*8. but still she rather found this kind of symbol processing painful and preferred to play with other things. another approach we tried to show her a visual representation of the multiplication but not sure what her current progress is.

that feels like a nice application of AI in a way. we often use a computer that can help in making a plan (e.g. a kind of map or "steps" as here). this might be nice to help understand problem solving in general. also, nice to see the project is in javascript, that means quite a few non-professional programmers could learn from it.

interrupts in out-of-order processors were the topic of last's week coursera comparch course https://www.coursera.org/learn/comparch - nice to see the discussion for a smaller machine

really nice project - i was playing with compilers and javascript a while ago see http://embeddednodejs.com/compiler - as a simple experiment to learn about javascript's role in compilers

Re:Koto.js – A D3 charting framework written in ES6 on Friday November 18, 2016 @02:18AM (#12984977)
indeed, first thought was how does it differ from classic d3 charts ? i like d3 a lot, but usually it takes some boilerplate code to setup charts. when working with multiple datasets the d3 commands look a bit confusing at times, so higher level abstractions are interesting to see
