First we need to know what a programming language is. At its minimum, a programming language is something that is read by the computer and instructs it to perform certain operations. Many people would also expect a general purpose programming language to be Turing complete. However there could be situations where a domain-specific language isn’t … Read more
The best explanation I heard for Monkey patching/Duck-punching is by Patrick Ewing in RailsConf 2007 …if it walks like a duck and talks like a duck, it’s a duck, right?

This determines how much precision the GPU uses when calculating floats. highp is high precision, and of course more intensive than mediump (medium precision) and lowp (low precision). Some systems do not support highp at all, which will cause code not to work at all on those systems. On systems that DO support highp, you … Read more
“BC break” usually means backward compatibility in a general term, but as David Schwartz said it can be interpreted as binary compatibility break in some contexts.
Grid computing is where more than one computer coordinates to solve a problem together. Often used for problems involving a lot of number crunching, which can be easily parallelisable. Cloud computing is where an application doesn’t access resources it requires directly, rather it accesses them through something like a service. So instead of talking to … Read more
There is also jsonc aka “JSON with comments”, created by Microsoft and used by Visual Studio Code. The logic for it can be found here, alas without exhaustive specification (though I’d like to be proven wrong on this). On top of that there is this project with an actual specification which is also called jsonc, … Read more
Caution, SCM can refer to different meanings about Versioning: Software Configuration Management as explained in JimDaniel’s answer Source Control Management is same as Version Control and Source Control and VCS Moreover, people may use SCM to refer to other naming: Source Code Management as in Source Code Control System Software Code Management but this is … Read more
GUID is the acronym for “Globally Unique Identifier”. A GUID is mainly used to produce hexadecimal digits with groups separated by hyphens for uniqueness purposes, for example: b3d27f9b-d21d-327c-164e-7fb6776f87b0 In postman you can use this to generate and send a random GUID to your api as required: { “id”: “{{$guid}}”, } On Send would produce(with the … Read more
A crawler gets web pages — i.e., given a starting address (or set of starting addresses) and some conditions (e.g., how many links deep to go, types of files to ignore) it downloads whatever is linked to from the starting point(s). A scraper takes pages that have been downloaded or, in a more general sense, … Read more
