We will compare ASP.NET and Node.js for backend programming.

async/await. yield and await are used almost in the same way, so I see no point to rewrite the examples.
About my endeavor to automatically retrieve grammar of CPython .pyc-files bytecode from Python's sources itself (success) and build parser on them (failed).
Most recent version of this article is always on GitHub
In 2011 as part of my diploma thesis I came up with an assembler language for .pyc files and wrote a simple proof-of-concept assembler for it based on ANTLR3 parser generator. Back then I stumble upon the issue that CPython bytecode is somewhat not stable and differs from version to version. I.e., as of Python from 3.0 to 3.4 there are 28 incompatible bytecode versions (you may find all bytecode versions with their descriptions in Python34/Lib/importlib/_bootstrap.py).
So, if we aim to devise an assembler or disassembler not for one bytecode version but for many, we face a routine of retrieving out these bytecode differences. This task strikingly
We will consider C and Java implementations for DFS and BFS graph traversal algorithms (4 programs) and compare their source codes and binaries to figure languages shortcomings and fortes in application to the given task.

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).
The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

Though Windows update program is over, you still may use old Windows product keys from license stickers to install Windows 10 on old machines.

This note/example shows 3 different ways of handling promise rejections in JavaScript.
Before we start you may want to refresh in your mind that:
.then(...) takes two arguments: MDN..catch(...) is a syntactic surgar around .then(...) with two arguments: MDN.Exceptions that are thrown in the callbacks of then() and catch() are passed on to the next error handler, as rejections
