It must be borne in mind that the tragedy of life doesn’t lie in not reaching your goal. The tragedy lies in having no goal to reach. It isn’t a calamity to die with dreams unfulfilled, but it is a calamity not to dream. It is not a disaster to be unable to capture your ideal, but it is a disaster to have no ideal to capture. It is not a disgrace not to reach the stars, but it is a disgrace to have no stars to reach for. Not failure, but low aim is sin.

IM clients and deleting conversations
- https://en.wikipedia.org/wiki/WhatsApp
- https://en.wikipedia.org/wiki/Telegram_(software)
- https://en.wikipedia.org/wiki/Signal_(software)
I sort of like the feature to edit sent messages. I can somehow tolerate, that some messages can get deleted by the sender at any time. I cannot tolerate at all, that one participant can remove an entire conversation. I think the only one of the above to not support the removal of an entire conversation is Signal.

Go lang: Compiling your Tool for Different Platforms
- https://golang.org/src/go/build/syslist.go
- https://pragprog.com/book/rggo/powerful-command-line-applications-in-go
I like it, that with Go lang you can cross-compile without significant effort and straight away. E.g. I can compile a tool for Linux or for Windows on the Mac.

Mine cost me EUR 300 (+ …). If you are able to switch to it, it solves you a lot of problems. I guess most people would be better of switching to this kind of computer – would you like more explanations? I don’t earn money on this. I do have such a piece and I can demonstrate it to you. It is modern, it is fast, it is nice. Honestly! Give it a try!

Catalina, fink, …
I was quite enthusiastic to install Catalina right after I read the notification of its availability on my MacBook. I installed it right away, but upon completion I got aware of that the fink installation at /sw was gone, because Apple made the root directory read-only. The fink project suggests installing fink at /opt/sw. Installing fink like this did not work on Catalina. I downgraded to Mojave. (I had to erase my disk in order for this to be possible.)
The old /sw fink installation, that I had saved to my NAS and that I restored was (resp. looked) (sort of) worked, but I was tempted to install a new fink to /opt/sw, and I went for it. During this new fink installation (“fink selfupdate-git”) this message showed up:
WARNING: Xcode.app version (11.1) and Xcode Command Line Tools version (10.3)
may not be compatible.
You may experience build errors.Where to find “Xcode Command Line Tools” to install them from?
Go to https://developer.apple.com/downloads, search for “command line tools for xcode” and get the most recent one DMG, and also install it! After installing it I still see that message, but (11.1 vs 11.2) is still better than 11.1 vs. 10.3, I think.
CAVEAT!!! Read this now:
