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).

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)

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

Regards

Richard

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...

Logging

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.Log with properties

TPC-E in Caché

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.

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.)

How to avoid dirty read

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?

Greetings to all! Faced with such a problem, I ask for help, someone with great practical skills I think has already implemented this. The task was not to delete any objects from the database, but somehow mark this data deleted by client, because of this, I added Property Deleted As% Boolean [InitialExpression = 0]; in the class. And in the redefined method %OnDelete:

I want to limit the length of the value of a textarea in Zen. In HTML the textarea element has a 'maxlength' attribute, but the Zen component doesn't have an equivalent property. Is there any way to add a maximum length in Zen short of creating my own custom component?

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
