It is often necessary to run some external command such as a python program or a shell script from inside Caché/Ensemble. There are three ways of doing this:
With the release of Cache 2016.1, JSON support was re-architected and made part of the core object model with the creation of %Object and %Array classes, which allow you to create dynamic JSON enabled objects and arrays.
On a recent demonstration I was working on, I had the need to create a REST web service that returned a JSON representation of a persistent object. After searching for methods that would allow me to accomplish this, ultimately I found none, until now.
The challenge of day 16 is about generating random data using a modified version of a dragon curve (you can find more info on fractal curves like Dragon here : https://en.wikipedia.org/wiki/Dragon_curve).
The challenge today is about some basic cryptography : you will have to generate data for a one-time pad (OTP) (see https://en.wikipedia.org/wiki/One-time_pad for more info).
Today's challenge is about decompressing input that is compressed in an experimental format. In the format, markers indicate how much time a number of characters need to be repeated.
The input in today's challenge consists of an encrypted name, a dash, a sectorID, a dash and a checksum between brackets. A name is real if the checksum is equal to the five most common letters in the encypted name.
The challenge of day 5 is to calculate a password of 8 characters by finding the MD5 hash of the input and an increasing integer index. The password is constructed by taking the 6th character of the first 8 hashes that start with 5 zeroes (in hex representation).
