I haven't found any backend developer that has labelled himself/herself "fullstack". In my country, so far the "fullstack" developers i've seen are the JS frontend guys that learnt how to do server dev in

Really cool pictures! Light bulbs are sometimes used for stabilizing oscillators. I think it works like an (audio) volume "compressor" would. For example the Thorens TD125 turntable uses a light bulb as part of the oscillator circ

The article is a well written, well illustrated guide to programming under Javascript using an event loop, callbacks, etc. Which I personally find awkward to do in 2017 where the OS or the language runtime should give me better concurrency

Thanks! You made my day!! And the "burgled-batteries" name was a good laugh! (If Python is "batteries included", let's steal those batteries!)

The only problem is that everytime he/she wants to execute Hy (Python in s-expression syntax) code, he will invoke the macro "org-babel-execute:hy", and this runs Hy as a shell command. So Common Lisp objects can't be qu

Really big apps have existed since the early 70s. I'd argue that the average application size gets lower every year due to the increasing number of specialized libs every year. And C++ has supported generics long before the boom in pop

I also find the opposite to be true, as you do. The human mind and human problems, operate more like a dynamic language. To put it in a simple, silly example: When i tell you to "cut something with a scissor", the scissor doesn&#x
