Problem statement:
Given a string, look for a mirror image (backwards) string at both the beginning and end of the given string. In other words, zero or more characters at the very begining of the given string, and at the very end of the string in reverse order (possibly overlapping). For exampl...
For a web application, I have to transform a LaTeX document on the fly into an HTML string, that is delivered to connected clients via websockets.

While watching this Signal Path video, I came across this shot:
I saw few rigid coaxial cables there and so I started wondering what might their advantages be. I could only find disadvantages:
They're expensive
Limited in available angles 45° or 90°. Otherwise they're not easy to bend compar...

Recently I solved a challenge on abbreviating and expanding IP v6 addresses. For that matter, I had to write two functions, AbbreviateIPv6 and ExpandIPv6. The first function ought to take a character vector of a v6 IP address and abbreviate it like this online tool. The second function ought to u...
I wrote a few separate classes that all read from the same json config file. To minimize redundant code there's a separate module that contains a load(object) method to read from the config file and sets obj.x and obj.y and so on from that info
For at least one class though there are no other va...
The code below reads a json config file listing a series of apis and the base urls, loads a handler script that extends a parent Handler class for each, and then passes a list of the loaded Handler objects back to an Aggregator that goes on to do database stuff with them
The goal (which works cu...
