Unsupported Operating System and Failed to connect to MySQL - installation

I am trying to install MySQL but I get the following warning:
I have a Mac and its installed the latest version 11.6 , so I don't understand why it says its not supported.
After that warning I tried to install a connection to MySQL server and I get an error:

I downloaded not the last version, but the second last and now everything it's fine. I know its not a "nice" solution but now I have no warning message and I successfully made an SQL connection.
The version I downloaded is:

Installing OracleXE 21c through Proxy on Windows

I have trouble installing OracleXE on my company PC, when installing it fails because it can't download the file "exectask.exe" and throws an error later saying, the file is missing.
The Problem seems to be, that the installer don't use the Proxy defined in the system variables. When trying to install an older Version (11g) this Problem doesn't occure.
Is there a way to give the oracle installer the Proxy directly?
Sincerly,

Rstudio not working on my Ubuntu 16 virtual machine

When I try to run Rstudio Desktop (1.4) on my virtual machine (Ubuntu 16.4), Rstudio crashes and gives the error:
ERROR:gl_surface_glx_gt.cpp(141) GLX 1.3 or later is required.
I tried to follow the instructions on this page: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround, but can not get past the meson -D configuration in the Ubuntu terminal. At this point I get the error message: 'ERROR: Problem encountered: gallium-xlib conflicts with any dri driver'
I googled and tried everything that I could possibly find (similar questions as https://community.rstudio.com/t/x2go-and-rstudio/29704/2), but no success yet.
Obviously the upgrade to a higher GLX version is the cause, but I can not upgrade it.
Is anyone familiar with the error and what is actually causing it?
Any help would be greatly appreciated!
I am using R version 3.4.4

Fails Brew Elasticsearch Failed

Upgraded to V7 yesterday via Brew now ES won't start:
OpenJDK 64-Bit Server VM warning: Ignoring option CMSInitiatingOccupancyFraction; support was removed in 14.0
OpenJDK 64-Bit Server VM warning: Ignoring option UseCMSInitiatingOccupancyOnly; support was removed in 14.0

Error: Could not create the Java Virtual Machine.

Tried to reinstall and updated the Developer Tools.
Crazy issue that I finally tracked down - I hope this helps someone else. Edit this file:
/usr/local/etc/elasticsearch/jvm.options
# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=/usr/local/var/log/elasticsearch/gc.log:utctime,pid,tags:filecount=32,filesize=64m
# due to internationalization enhancements in JDK 9 Elasticsearch need to set the provider to COMPAT otherwise
# time/date parsing will break in an incompatible way for some date patterns and locals
9-:-Djava.locale.providers=COMPAT
Then create the /usr/local/var/log/elasticsearch/gc.log file. Restart ES via brew (brew services restart elasticsearch) and you are good to go 👍

postgres create database; column 'dataconfig' does not exist

I've just installed PgAdmin 8.4 on an OSX Lion 10.7.3 pc with Postgres 9.1 installed.
When I try to add a database, I get an error message:
"Error: column 'dataconfig' does not exist"
Does it mean a mismatch between client and server versions? I couldn't find a later PgAdmin version.
If you mean the pgAdmin version that is bundled with some versions of postgresql 8.4 then that version is to old. It is inspecting the system catalogs to figure out the database lay-out but it doesn't support the 9.1 version of the system catalogue. If you used the one click installer you can use the bundled pgadmin. You can find it in Applications/PostgreSQL 9.1/pgAdmin III.app
Otherwise download the latest from here
Try pgadmin3-1.16.1 - it works. I've tried with many other versions (for example pgadmin3-1.8.3 and pgadmin3-1.16.0), but without success.
