Quick-Tip: Solving a problem with Letsencrypt and Python < 2.7

Tuesday, April 9, 2019 at 12:35 AM UTC
I just stumbled upon a problem on my older system as I tried to update my SSL certificate with Letsencrypt. The certbot-auto script stopped working and gave me errors regarding the pip module. As of version 0.32.0 Letsencrypt stopped supporting Python version older than 2.7. There is a solution though: The line numbe [...]

macOS in black and white - WTF?

Wednesday, March 13, 2019 at 8:37 PM UTC
Tonight I sat on my studio iMac to make some music. Suddenly by screen lost colors and turned black and white, preceded by some flickering. I first thought it was Chrome's fault as it updated to version 73 which brings the dark mode to macOS devices but it wasn't. After a restart the color went back. But the problem persisted. After some investigation I found out that this is a macOS ac [...] 

Quick-Tip: Instruments missing in Maschine/Komplete Kontrol?

Wednesday, March 13, 2019 at 8:22 PM UTC
I just stumbled upon the fact that Native Instruments' Maschine and/or Komplete Kontrol plugins won't show up as expected when used in your DAW as a plugin directly. The browser window did not appear and for Mschine it's essential to choose your kit or instrument to work with. Other to when using those programs as stand-alone versions the browser might not show up. But it's easy to [...] 

Some hints for trying out DQL Explorer

Yesterday IBM released the prototype version of the DQL Explorer that was demoed some weeks ago at IBM Think by Luis Guirigay on OpenNTF and Github. Of course the interest was tremendous and so I was enthusiastic to test it out. However, there are currently some caveats to deal with and this post explains what I found so far. There are three different ways to get into the deploying process o [...] 

ADMIN_CLIENT_SKIP_DOMINO not working on Domino 10?

Thursday, March 7, 2019 at 10:52 PM UTC
I just noticed that the server's notes.ini variable ADMIN_CLIENT_SKIP_DOMINO=1 seems not work with Domino 10 anymore. I tested on V10.0.1 and the setting is defined in a configuration document. Maybe someone from HCL can confirm this issue and create an internal "case"? Update: It seems to be Linux only, Domino 10.0.1 on Windows acts as expected. For all who are not aware [...] 

Potential bug in Domino Access Services API

Wednesday, March 6, 2019 at 3:30 PM UTC
Just encountered a problem with Domino Access Services API (DAS). When using the endpoint to get all calendar entries of a given user with https://hostname.local/mail/tbuktu.nsf/api/calendar/events and you don't have any entries in the calendar, the response will be empty. It will be a 200 response though but the expected result would be an empty JSON object {} and not just "n [...] 

Quick-Tip: Starting Domino IAM as a service

Tuesday, March 5, 2019 at 10:46 PM UTC
Today I continued to work on our internal company server which will provide the IAM service. As the service app prompts for the service password when starting it’s not possible to use my favorite process manager for Node.js called „pm2“. Instead a colleague mentioned „screen“, a terminal multiplexer. I knew this little helper before but never used it. Now it comes in [...] 

Domino, Proton, IAM, OAuth - Part 4: IAM service

Monday, March 4, 2019 at 8:51 PM UTC
Sorry, folks, I had a week off but here we go again! Get ready for some console typing action! This is all about signing certs and creating new certs that will be used for the IAM application. You will also setup the IAM service app that has to run in order to setup your apps with OAuth, LDAP and the authentication via OAuth. In the Domino App Dev Pack unpack the archive domino-iam-servic [...]
