Today's challenge is a variation on the White Elephant gift exchange (https://en.wikipedia.org/wiki/White_elephant_gift_exchange), in this case, by a bunch of Elves where only one can have all gifts.

Each Elf brings a present.They all sit in a circle, numbered starting with position 1.Then, starting with the first Elf, they take turns stealing all the presents from the Elf to their left.

You walk into a room, step on a tile and hear a loud click...

Traps !

The challenge is about avoiding traps.

You can recognise if a tile is a trap by following scheme :

The first row is a given : a safe tile is shown as . and a trap is shown as ^
For the next rows, the state of a tile is calculated related to the tiles in the previous row (same position, tile left and tile right).
If the tile is

The challenge today is again a-maze-ing (as a wellknown president would say).

The maze has a bunch of doors ( | and - on the drawing), but they can be locked depending on a hash that you need to calculate every step.

I'm trying to write a method to Export SQL Privileges from an instance by namespace, user, or roles. I've found two classes that might work:

• ##class(Security.Users).Export
• ##class(Security.SQLPrivileges).Export

One (Security.Users) exports an XML file and the other (Security.SQLPrivileges) exports an SQL file.

Neither of these options allows me to specify specific users or roles to export so I'll have to use them in tandem with something else. Is there something else that I should be using or do I need to find a way to filter on the backend with regular expressions or the like?

Any suggestions on the most efficient way to convert yyyymmdd string to mm/dd/yyyy?

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).

First you need to generate data in a loop as follows :

Call the data you have at this point "a".Make a copy of "a"; call this copy "b".

I'm looking for information, suggestions, video (courses) on make a lot more use of the documatic system already built into Cache,

Probably talked of before within this forum, but after an hour or two of searching, can't find the articles that I mmay have seen before.

I want to do a lot more documenting of my installation, we use and actively comment classes and methods, but I want to take it further by actually documenting the "why" and high level "how" my system works. Documatic seems a good place to put that knowledge.

This may, but probably not after your suggestions, involve creating a

Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Hello Caché Guru,

I'm new to Cache system. I'm trying to do something like saving meta data in Relational DB:

I could use "management portal" -> System Explorer->SQL to view individual table's catalog details or print out the column definition. However I need to gather those information for several hundreds of tables in the DB. Is there a way to do it using command line in kind of batching mode?

Any hint and tip is very much appreciated!

Thanks in advance!

One for Luca, perhaps?

Interesting article here:

Would this be a fit for Cache / IRIS containerisation?

Not sure I fully "get" what's being proposed in the article, mind you.

The challenge for today consists of capsules that bounce through a maze of spinning discs.
The capsule can fall through a hole of each disc if they hit the disc at position 0,  each disc has a fixed amount of positions that rotate every second.
The distance between the release and the first disc is one second, as is the distance between each consecutive disc as well.

Hi everyone,

I started working on Ensemble this year so maybe I am not implementing the right way. I'm trying to connect a Welch Allyn monitor to TrakCare. The workflow is the following:

- User scans patient number with the monitor.

- The monitor sends a QBP_Q22  message to request patient information

- Ensemble (or TrakCare) sends back a synchronous RSP_K22 containing the patient data (name, dob, sex)

- The user checks the patient's information displayed on the monitor, takes vital signs and sends them to TrakCare (via Ensemble)

I designed a DTL to build the RSP_K22 message using a query that

I am using Cache FTP classes to download from a FTP site files, that include zip files.

Hello,

I'm looking for a way to programmatic ally add the parameter 'VALIDIFNULL' to classes that extent %SerialObject.

This to hopefully resolve the validation errors I'm getting  on webservice request messages, where certain properties are not required, but lower down the tree some properties are.

I have too many classes to do this manually and with the next SOAP wizard run I probably loose the added parameter.

Some help would be very much appreciated.

I searched fror "documenting classes" from the search button with no filtering. it naturally came back with 559 responses, but to me, the responses (and therefore the search)  came without context.

for instance,  one of the texts came back with:

Hi, folks!

Consider I need to perform some logic which should fire because values of object properties has been changed.

Is there ANY reason for using class callbacks %OnBeforeSave or %OnAfterSave instead of Trigger?

I have a couple of new namespaaces/databases that are read-only.  I don't remember changing them to read-only, and although my username has %all (I installed the system), I am unable to change the "Always mount as read-only" property.

What am I missing?

Thanks,

Laura

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).

You need to generate keys by taking the MD5 of a pre-arranged salt (your puzzle input), and an increasing integer index starting with 0.

Only those keys are valid which have :

Hi communauty

I’ve hit the wall. I’m a one person shop who wants to start developing Cache on a mac using Eclipse/Atelier, after using Studio for the last 5 years. I’ve installed the 1.1 beta plugin, watched 6 or 7 videos from the September conference, tried several times to work through the cheat sheets, only to have connection issues or compilation issues, so at this point, I’m feeling very frustrated. The videos were interesting, but generally didn’t work as tutorials for fundamental programming operations, for me.

I feel comfortable with Objectscript and Zen development in

Hello guys,
I'm having a problem on a sign-up screen, what happens is that this screen is not reloaded after clicking save, and that's where the problem arises, on that screen it is possible to upload images, but as everything is loaded withsubmit, the record would have to be updated so I had all the information, which does not happen.
With this I'm trying to find a way to get the information from the file loaded in the "file" component to get the data in "% request.MimeData".
The only way I've found it so far has been to reload the whole page, but that's all I do not want to do.
This page has

A third party developer has asked for access to the documentation of my classes so he can understand my tables/classes better.

• How do I give access the the documentation of my classes (single namespace)  and secondary, do I need to give  him access to %system. (and others)
• Is it possible to block the likes of ensemble, Iknow, deepSee etc. I don't use those, and I don't want him to waste time (and my money) exploring areas that simply not necessary
• what privilege roles do I need to give him  whilst still maintaing security.

Today, you have to find a path through a maze. To know if a coordinate is a wall or an open space, you will have to do a calculation like this :

Add the office designer's favorite number (your puzzle input).Find the binary representation of that sum; count the number of bits that are 1.  - If the number of bits that are 1 is even, it's an open space.
