This is a series of programming challenges for beginners and experienced Caché programmers.

For an introduction : goto to article https://community.intersystems.com/post/advent-code-2016-day1-no-time-ta...

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).

Advent of Code is a series of 25 small programming challenges, it's an ideal way for beginners to start learning a computer language, and for advanced people to sharpen their programming skills.

There are small and bigger puzzles, which you can solve typically in half an hour to a few hours. (Looking at the leaderboard, the top aces can do them in less than 10 minutes.)

Advent of Code is created by Eric Wastl, you can find all info on https://adventofcode.com/.

Hi,

I know you're doing a big effort to build a new IDE in Eclipse ecosystem but Visual Studio Code is a new an even better and faster tool for coding... did you have any plans to release any COS extension for it in the near future? There you can already find extensions for all current more common progrmaming languages and it would be great to have COS as one of them.

Thanks

Rebuild class index

I have a class. In class there is an index. This index is for quick search on name property.

Class User

This class is mapped to some global ^GL(userId) = "Name*other data....****"

And there is also index global ^GLNameIndex(Name, userId) = ""

When I add new User entry through class, f. i.

S user = ##class(User).%New()
S user.Name = "Some name"
​D user.%Save()

calling method %Save() adding new entry to index automatically.

Hello again and welcome to the next tutorial on this series: Part 4 - Sharing data across router methods. Here we are going to learn how to share a object containing data that is available for read across every router methods.

You're required to complete at least the Part 1 before entering this one. Still, this is supposed to be a really short tutorial, since there isn't much to be said about data sharing.

Hello again and welcome to the Part 3 - Using the SQL API!

If you have been wondering about how to use SQL along with Frontier, you came to the right place. That's because since Frontier wraps the common Caché SQL API within it's own, you need to use the API provided from it. But you don't need to worry about its learning curve, because the Frontier SQL API is really simple.

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.

Hoping someone can help.

I need to convert a timestamp from the following format (YYYYMMDDhhmmss e.g. 20160105125915) to UTC time in the same format.

I presume I need to convert it to the system format ( like $HOROLOG ) and then use something like ConvertTimeStampToHorolog or perhaps LocalWithZTIMEZONEtoUTC but not sure of the syntax.

Thanks,

Conor

Searching Refactoring tool

Hello everybody,
we would like to be able to analyze a rather complex software application, which has been programmed in “M” for a number of years by different developers, by means of a tool.
Our goal is to find a starting point for a code refactoring process. In the long run we would like to gradually eliminate the code growth points.
Does anyone know of a tool that can help us to do this?
So far, we have only found "RE / m" etc. by George James Software, but we do not yet know if these tools will help.

Hi all.

I have been using a command pipe to open/run UNIX scripts for months without issue. We recently installed the 2016 Caché Upgrade and now I'm getting the following error when opening the pipe:

<PROTECT> *OPEN[Q](|CPIPE|)

I assume some security or permission setting is to blame, but I'm not sure exactly what. Here's the snippet of code...

s cpipename="|CPIPE|"
s filepath="/path/script"
​o cpipename:(filepath:"R"):10

Any feedback would be greatly appreciated!

Extract piece of string

Hello guys,

I was wondering whether there is another alternative to extracting a certain string out from a bigger one, rather than using the function $piece.

Maybe regular expressions? Another specific function?

Example:

Big string:

NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere

String I want to extract:

TextIsHere

Function I'm already using:

Cache 2016.2.1

the system offers $LISTNEXT as a way of looping in $LISTs and the documentation says this is much more efficeint than writing

for i=1:1:$LISTLENGTH(myList) { set value = $LIST (myList,i) }

I want to walk backwards in the list,

is there a $LISTPREVIOUS or do I have to use the followng syntax to achie

 for i=1:-1:$LISTLENGTH(myList)

Level up your XDATA

XDATA is used for a whole host of ISC libraries to store things like Zen pages, BPL logic and DTL transformations.

XDATA is the equivalent of XML config files of the JAVA world and JSON config files of the JavaScript / NPM world.

Whilst Atelier looks to shift source code to the disk, XDATA will remain a key component to source control our projects config / meta data.
