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.

The challenge of today has nothing to do with real two-factor authentication ! (sorry if you came to this article by searching the real thing)

For the complete explanation of the challenge, go to http://adventofcode.com/2016/day/8.

Your input (http://adventofcode.com/2016/day/8/input) consists of a series of three basic instructions to control the display of a screen.

Is there documentation that states %Id() is supposed to be available in %OnBeforeSave()?

I am currently using it in this method without issues, but one of my colleagues is stating it is not supposed to be available for a new object at this point because the object has not been saved yet.  

I tried to implement the Oauth2 in google,

I got authentication, But I unable to read response class.

I got an error as:

I unable to change response Class.

Anyone help me to Change response Class in Client Configuration

                      or

Is there any option to define response URL manually?

Thanks

So we are still fairly new to the ensemble app and getting set up. I have 3 seperate  batch record file services that pull in files and send to 3 seperate processes. there is no real rules other than an when condition=1 use this said DTL and send to operation. all 3 of these routers use different DTL's as they are seperate files but all go to the same operation. for some reason i am seeing the files sit in the Process and say  Delivered. 2 of the three process after up to 10-15 mins of sitting and the third gets an error i am very unfamiliar with, so this post is two-fold.

Hi-

Please excuse my rather limited knowledge of HL7.

In Ensemble, I have a HL7 message that contains several Z segments.  I have created a custom schema to represent the new Z segments along with the new DocType Structure and Message Structure

How does Ensemble/Health Connect know which custom schema to use?  I believe it has to be indicated in the MSH segment somewhere, but not sure where exactly that would be.   Is the version simply updated with the new schema name or is there some other field?

TIA

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.

Hi Community. I have a vendor sending us X12 837 claims, they are sending a mixture of 4010 and 5010 formatted claims. Is there a way I can examine the file contents and determine the message format and route to two separate folders based on format (4010 vs 5010). I've tried setting up a record map, stream container and vdoc services and processes with no luck. Any help would be appreciated.

I am a newbie to Cache and we are using dBeaver product to query against Cache tables. I have the following query which does a GROUP BY to aggregate the columns:

SELECT PtNumber,cpt4_OVR,CollDateODBC, COUNT(*)
FROM site.MGBILL_View 
  WHERE cpt4_OVR IN ('36415', '36416')
     --AND ChargeFlags = '0'
       AND CollDateODBC > DATEADD(DAY,-45,CURRENT_DATE)
  GROUP BY PtNumber,cpt4_OVR, CollDateODBC
  HAVING count(*) > 2

-This returns a count of 3 for each patient (aggregated)

But I need to display the actual 6 rows.

Hi I've created a word macro in order to convert doc to txt via the command line, this works fine via the command line by myself or another user but when I try as an the intersystems user which runs under  LocalSystem it doesn't work. 

So can I change the user, or set the $ZF to run as a different user?

Or do I have to try another way to convert doc to txt - it's looking like libreOffice?

I just wanted to stick with word because I could be guaranteed on the result being accurate.

Thanks

If you want to dynamically serve images as a property of JSON then there is no perfect encoding solution. One method used frequently is to Base64 encode the image. Whilst there are some negatives to doing this, such as data inflation, there are some positives to working with Base64 images inside the browser.

Let's say you have an image placeholder on a web page...

And you fetch a JSON message from the Caché server containing the image as one of its properties...

I have an Ensemble installation with an FTP business operation which I would like to connect to a server over SSL in explicit mode (see also: https://www.rebex.net/kb/tls-ssl-explicit-implicit/default.aspx). I keep running into timeouts while attempting to do this via Ensemble. Does Ensemble actually support SSL in explicit mode??? Because I can't seem to find any setting where to switch it on.

Hi,

Is there a report of ports configured by services?

We have a lot of services, across multiple namespaces, and it would be useful to know what ports are configured, even for disabled services.

Hello, evrybody, I'm writing one project using CSP("OnPreHTTP"), and also REST angular. At the beginning I wrote purely on csp, then I decided to use angular for the flexibility of the client part. Now I can not design logging, I created a table App.

I work in a small development company that uses Caché as a database. In some support cases I have doubts about whether the client's infrastructure environment is not affecting Caché's response time. Reading a bit about comparing installations in different environments, both in production as testing and homologation environments , I understood that the TPC-E is a benchmarking method accepted in the market.
I'm reading the specifications of the TPC-E and I wonder if anyone has implemented or seen something similar in Caché.

Hello; We are managing several Ensemble instances on several servers.  One server has 4 instances, and two other servers have one instance each (those are production servers).  We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

What I'd like to know is what are the best practices for managing encryption keys for separate servers.

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

ClassMethod testInsert()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))
  hang 15
  &sql(ROLLBACK)
}

ClassMethod testRead()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED)
  &sql(select count(*) into :ans from Test.Table)
  &sql(COMMIT)
  w !,ans
}

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live.  Or does this even matter?

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.

 Method SelectPaceartCharges(pRequest As osuwmc.Paceart.DataStructures.SelectPaceartBillingExtract, Output pResponse As EnsLib.SQL.

Hi guys,

     I have accidentally clicked the remember password option in my Ensemble studio. So it is now not asking for username and password and even the authentication popup is not showing every time i open the studio.

    Is there anyway to remove the remember password option for the cache studio.

Thanks,

Hi guys,

   I am trying to run a command line code using $zf(-1) in cache terminal. it is returning access denied error.

I have tried to run the code in cmd itself it is also throwing Access denied error. But if opened cmd as administrator and run the same code it is working perfectly. I am using windows system. 

Hence i need to know how can i run the cmd line code as administrator using our terminal or studio. Please help me out.

Thanks,

Mani

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.
Full description can be found at http://adventofcode.
