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

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 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).

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.

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!)

Question Sergio Martinez · Oct 16, 2017

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

Question Ruslan K · Oct 18, 2017

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.

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.

Question Mack Altman · Sep 26, 2017

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 }

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.

Question Marco Blom · Sep 22, 2017

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.

Question Mack Altman · Sep 6, 2017

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.

Question Conor Browne · Sep 19, 2017

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

Question Mario Birk · Sep 21, 2017

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.

Question Donald Bugbee · Sep 15, 2017

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!

Question Murillo Braga · Aug 31, 2017

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:

w $piece("NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere","NAD+SLA+++",2) > Will ouput TextIsHere
w $piece("NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere","NAD+SLA+++",3) > Will ouput TextIsHere

Thanks!

Question Kevin Furze · Sep 13, 2017

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)
