Recently I already mentioned project Cube for macOS, which can be used to easily get access to Management Portal and terminal

I have not touched Trak before, but I'm sure they don't use plain CSP pages and use at least CSP classes. Why do you need CSP files?

I have configured automatic deployment of the application to Kubernetes with Helm from GitLab as a part of CI/CD process.

I would not say that I had some specific issues, just well configured Kubernetes cluster with the right storage driver. Any InterSystems products supports devicemapper and aufs right now, yet. So, of course, better to have devicemapper available server, and use this possibility. AUFS already deprecated by Docker and will disappear in the next major release.

Do not forget that $lb is just a list, concatenated list of single $lb, and $lb is a string in binary format.. So, just $replace, will work

USER>set list = $lb("stri,ng", $c(0), 2)

USER>set list = $replace(list, $lb($c(0)), $lb())

USER>zw list
list=$lb("stri,ng",,2)

You can specify /nodelete qualifier when you run your tests.

Do ##class(%UnitTest.Manager).RunTest("testspec","/nodelete")

Look at the documentation for other options.

Well, now a few questions.

Does it mean that any new requested features will be declined to implement?

Any possibility to implement new features by own?

How about the future of Atelier API?

If InterSystems not going to extend Atelier anymore, maybe it's time to open sources Atelier or at least Atelier API.

Currently, it sounds like Atelier will get the same future as Studio, it means no future. Or am I wrong?

In addition to other answers, if want to operate with bits, you can use functions:

• $zhex - converts integer to hex and vice versa, be careful with type of variables. If you pass string it will convert from hex to dec, if you will pass integer it will convert from dec to hex.
• $factor - converts integer to a $bit string
• $bit (with bunch of $bit* functions) - operates with bitstrings.
• You may possible need some encryption functions, you can find
• And possible zlib, $system.Util.Compress and $system.Util.Decompress from class %SYSTEM.Util 

If you are going to work with H.264, I would not recommend to try to implement it in COS, it will not be fast enough. I'm not very know with this technology but I'm sure I know, it is too complicated and encoding should work in GPU. But it is impossible with Caché. I don't know why exactly do you need it, but I would recommend you to look at external tool ffmpeg, which is very useful and leader on work with video. And I think you can connect ffmpeg.dll, to work from Caché with $zf functions.

This format does not contain information about timezone, so, you don't have any direct way how to convert it to the local time. You can use DATEADD function, to correct time, but you should use constant correction, or in another field.

SELECT DATEADD(hh, 3, CreationTime) FROM Table

Like, here I just add 3 hours.

If you work on versions 2016.1 and later you can use native JSON.

KILLdes only happens during transaction, so, it will be able to revert changes.

And it happens when you kill some node with existing subnodes. So, it will kill each subnode separately with KILLdes

And it works exactly as it should be. I the first example it as a Boolean, and next as a string. What would you do if you would need literal "true", if it would converted to Boolean all the time?

Such message can be shown when you don't have enough license units. Do you have activated license there?

As you trying to install 2018.1.1, I suppose that you trying to connect it to IRIS, and maybe you just don't have a license for IRIS.

Is this error happens only once, or you can reproduce it?

you said that classes not compiled after that, but what said $system.OBJ.Load, is there were some errors, too?
