Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

• First Step: Reverse Cipher

  • Reverse the entire input string.
  • Relocate the last character of the original string (now the first character of the reversed string) to the end.

• Second Step: Alphabetic Index Binary Encoding

For my hundredth article on the Developer Community, I wanted to present something practical, so here's a comprehensive implementation of the GPG Interoperability Adapter for InterSystems IRIS.

Every so often, I would encounter a request for some GPG support, so I had several code samples written for a while, and I thought to combine all of them and add missing GPG functionality for a fairly complete coverage. That said, this Business Operation primarily covers data actions, skipping management actions such as key generation, export, and retrieval as they are usually one-off and performed manually anyways. However, this implementation does support key imports for obvious reasons. Well, let's get into it.

I have an Embedded Python method, which is essentially a call to one third-party module.

Most of the time, the method takes <0.1 seconds to execute, but sometimes it takes 30 or 60 seconds.

The server is relatively idle (20-30% CPU load).

How can I debug this issue further? Ideally, I want to know where this library spends the time. The library is mainly Python code (it's boto3, so it's not a Python C API proxy library).

When you deploy code from a repo, class (file) deletion might not be reflected by your CICD system.
Here's a simple one-liner to automatically delete all classes in a specified package that have not been imported. It can be easily adjusted for a variety of adjunct tasks:

set packages = "USER.*,MyCustomPackage.*"
set dir = "C:\InterSystems\src\"
set sc = $SYSTEM.OBJ.LoadDir(dir,"ck", .err, 1, .loaded)
set sc = $SYSTEM.OBJ.Delete(packages _ ",'" _ $LTS($LI($LFS(loaded_",",".cls,"), 1, *-1), ",'"), "/generated=0", .err2)

The first command compiles classes and also returns a list of loaded classes. The second command deletes all classes from specified packages, except for the classes loaded just before that. Any generated classes are also skipped since they won't be in the loaded list.

Today we have an unusual code golf: build a program (using only printable ASCII characters, tabs and newlines) that prints out exactly the characters in the printable ASCII space (characters 32 to 126) that don't appear in your program's source code (in any order, however many times you want).

As usual, the goal is to produce the shortest code to do this.

My (admittedly not very good, but does the job!) entry:

It's Friday and a long weekend is upon us, so let's have a round of code golf!

Nowadays, it's rare to find a text message without at least one emoji. 😃😄😎🙂😊😀😁😆😂
But back in the day, people had to be creative to express their emotions in text. They would use emoticons, which are symbols made up of keyboard characters :^) =] ) B).
Our challenge for today is to create a function that receives a string as argument and returns the total number of smiling faces or happy faces.
Each smiley face must have one smiling mouth, which should be marked with ), ], }, D or >.
A smiley face can have a pair of eyes but it does not have to. Valid characters for eyes are :, ;, 8, B or =.
A nose is optional, and can be represented these characters: -, ^, c, o and ~.

Valid smiley face examples:

    :) :D ;-D :~) :‑) :-] =)    
    :] :-> :> 8-) :D 8‑D )
    8) :-} :} :o) :c) :^) =]
    :‑D 8D =D B^D

Input

"count how many smiley faces are here :)"

​

Output

1

Let's have another round of code golf, with a different signature today!

Write a classmethod that will receive a variable number of parameters containing comma-separated strings and/or positive numbers, and returns one of four possible string values.

Welcome to the next chapter of my CI/CD series, where we discuss possible approaches toward software development with InterSystems technologies and GitLab.
Today, we continue talking about Interoperability, specifically monitoring your Interoperability deployments. If you haven't yet, set up Alerting for all your Interoperability productions to get alerts about errors and production state in general.

Inactivity Timeout is a setting common to all Interoperability Business Hosts. A business host has an Inactive status after it has not received any messages within the number of seconds specified by the Inactivity Timeout field. The production Monitor Service periodically reviews the status of business services and business operations within the production and marks the item as Inactive if it has not done anything within the Inactivity Timeout period.
The default value is 0 (zero). If this setting is 0, the business host will never be marked Inactive, no matter how long it stands idle.

Multi-tap or multi-press is the name given to the historic technique of writing SMS on the first mobile phones with a keyboard of 10-12 numeric keys.
For example, to type LOL you need to press 5 three times, 6 three times and 5 three times again.
Your task is to write a function that takes a string as input and returns the repeated digits associated with each character according to the multi-tap system.
