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.

I am trying to make Caché perform certain actions depending on whether a particular property of the object was changed using triggers.

For example, say I have this class:

    // ...

Today, you need to make a compiler for the language assembunny.
Luckily, this language has only 4 instructions :

cpy x y copies x (either an integer or the value of a register) into register y.
inc x increases the value of register x by one.
dec x decreases the value of register x by one.
jnz x y jumps to an instruction y away (positive means forward; negative means backward), but only if x

The challenge today is about microchips and generators. A microchip belongs to one particular generator, and the two can be on the same floor, or in the same elevator. But if a microchip is with another generator on the same floor or elevator, it will get toasted, except if his own generator is also on the same floor/elevator.
The elevator has only room for two items (can be mix of

In today's challenge, you have to execute instructions that control how bots are handling microchips.

The input contain instructions that can be something like this :

value 5 goes to bot 2
bot 2 gives low to bot 1 and high to bot 0
value 3 goes to bot 1
bot 1 gives low to output 1 and high to bot 0
bot 0 gives low to output 2 and high to output 0
value 2 goes to bot 2

Initially, bot 1

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.

For example :

A(1x5)BC repeats only the B a total of 5 times, becoming ABBBBBC for a decompressed length of 7.
(3x3)XYZ becomes XYZXYZXYZ for a decompressed length of 9.
A(2x2)BCD(2x2)EFG doubles the BC and EF,

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.

For example : 
aaaaa-bbb-z-y-x-123[abxyz] is a real name because the most common 5 leters are a,b,x,y,z (sorted by numer of occurences and alphabetically)

The challenge is to output

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).

For example : if the input would be 'abc', the first hash that has 5 zeroes would be by MD5 hashing abc3231929 : the hex

In today's challenge, you have to repair the communication with Santa : messages are coming in, but jammed.
By using repetition code (see also https://en.wikipedia.org/wiki/Repetition_code), you can find out what's in the message : by sending the same message a number of times, you can calculate which characters are most frequent on each position and find the most likely message.

For example,

Today's challenge on http://adventofcode.com/2016/day/7 is about checking for valid IPv7 addresses with TLS support. (No, it has nothing to do with real ip addresses which are at most ipV6 or real TLS, but just a way to keep you busy coding & hacking!)

The imaginary ipV7 addresses support TLS if they contain an ABBA sequence outside square brackets and no ABBA sequence inside brackets.

I am trying to replace one of our SQL Integration Service jobs with Ensemble and I am running into an issue executing a query against a MS SQL database using JDBC drivers.

My SQL Outbound code looks like this.

In this challenge, you need to find a password using instructions to move on a keypad.
Instructions can be U(p), D(own), L(eft) and R(ight).

You start at button 5 on a keypad like

1 2 3
4 5 6
7 8 9

each line of instructions lead to one digit of the password.

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/.

To help you get trained for this year's challenges which start at December 1st, we* will try to solve and comment the puzzles from 2016.

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

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

• Lot's of $c(10) control characters
• Multiple whitespaces

Here's an example of the text extracted from HTML page:

set text = " "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" Word1"_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_"

Example :

set property.Name = element.LocalName
set property.Type = "%Library.String"
set property.Parameters = ???

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

Class User
{

.....

Property Name as %String;

Index NameInd On Name;

.....

}

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.

And this way index ^GLNameIndex is always actual.

But in my program new user entry can be added

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.

Hi, Community! 

Please welcome a new session recording from Global Summit 2017:

A Mocking Framework: Laugh at Unit Tests

Recently, we scheduled two tasks (1008 and 1009) within Task Manager. Task ID 1008 is set to run after Purge Tasks (%SYS-ID:3), and Task 1009 is set to run at 7:00:00 each day.

In attempt to provide as much detail as possible, each of the tasks are as follows:

• Task 1008WHILE (($p($h,",",2) < $ZTH("10:00 PM")) && ($P($g(^Task.1008(+$h,$j)),"^",1) = +$h)) { J ^ROUTINE, ^ROUTINE2 D SUB^ROUTINE3 H 5 }
• Task 1009WHILE (($p($h,",",2) < $ZTH("10:00 PM")) && ($P($g(^Task.1009(+$h,$j)),"^",1) = +$h)) { d ^ROUTINE4, ^ROUTINE5 J SUB^ROUTINE6 }

The two tasks both reach an UNDEFINED error, which seems

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.
If you arrived here without checking the Part 1, I'd recommend you doing so, because Part 1 covers the essential for getting started with Frontier routers.

I have a tablepane which uses Sql to get his data:

As you look at the ''Business" column i have to type a number (key Value) to get the [Fashion Retail] value.

How do I have to modify the Built WHERE clause in order to filter on name /description of  the Join Fields instead of the key value? I would like to filter on name/description rather than a key value. Some sample code is appreciated! Thanks in advance.

Dear Developer Community!

My name is Maks.

I developed DeclarativeCOS framework for declarative programming on COS.

Today I want to ask you about New Programming Language.

I have an idea to create new programming language which could be translated to COS classes / routines or even to int-files.

So, lets suppose it is happened. What do you want to see in such language?

Please feel free to say your minds. It is open discussion.

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

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.

Your support and suggestions will be greatly appreciated. Thanks.

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!
