(76) Kurt Guntheroth's answer to I've heard that Lisp 'makes you a better programmer'. What is it about Lisp that strengthens your programming skills? - Quora
Having seen LISP probably makes you a better programmer. Seeing how small eval() is is mind-blowing.

Using LISP for anything is another matter altogether. Almost any text with the same number of left and right parentheses is a valid LISP program, which returns ‘F’ (false) when called. So LISP gives you no help at all finding syntax errors. This is a horrible way to learn.

By the same token, LISP tries very, very hard to execute any string of ASCII text you hand to it. It doesn’t give you much clue at run time what’s going wrong. Somewhat counterbalancing that, it’s very easy to call any LISP function, so debugging LISP was easy at a time in the distant past when debugging any other language was hard.

Don’t expect high performance from LISP. Higher than in 1979, but not high. Not many people even try to get performance out of LISP, so there is less effort devoted to making it fast.

LISP doesn’t offer much in the way of control or data structures. It’s like building a skyscraper yourself, out of atoms.

Scheme is a little better, but it isn’t LISP then, is it?

You should be OK *if all files in the backup are part of a single
atomic snapshot*. You can't put pg_xlog or selected tablespaces on
a separate filesystem that has a separate snapshot and expect the
various snapshot to be combined to be used as a coherent backup
unless you are archiving WAL and use pg_start_backup() (before the
first snapshot is initiated) and pg_stop_backup() (after the last
snapshot is completes) to take a PITR-style recovery.



Be sure to follow all the rules for PITR-style backup and recovery,
like deleting the postmaster.pid file and all files under pg_xlog
before starting the recovery. And of course, do NOT delete the
backup_label file created by pg_start_backup().

java 11 - How to install OpenJDK 11 on Windows? - Stack Overflow
Extract the zip file into a folder, e.g. C:\Program Files\Java\ and it will create a jdk-11 folder (where the bin folder is a direct sub-folder). You may need Administrator privileges to extract the zip file to this location.

Set a PATH:

Select Control Panel and then System.
Click Advanced and then Environment Variables.
Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
The following is a typical value for the PATH variable: C:\WINDOWS\system32;C:\WINDOWS;"C:\Program Files\Java\jdk-11\bin"
Set JAVA_HOME:

Under System Variables, click New.
Enter the variable name as JAVA_HOME.
Enter the variable value as the installation path of the JDK (without the bin sub-folder).
Click OK.
Click Apply Changes.
Configure the JDK in your IDE (e.g. IntelliJ or Eclipse).
You are set.

To see if it worked, open up the Command Prompt and type java -version and see if it prints your newly installed JDK.

If you want to uninstall - just undo the above steps.

Note: You can point the JAVA_HOME to the folder where you have multiple JDK installations and then set the PATH variable to a certain JDK. So when you want to change the JDK you change only the PATH variable and leave JAVA_HOME as it is.

IBM Removal of Tivoli Storage Manager V6 server instance on UNIX - United States
Problem(Abstract)
Failed install of a Tivoli Storage Manager V6 instance

Cause
In this case the Instance Install failed due to Tivoli Storage Manager format ran out of disk space

Resolving the problem
Do these steps (they are all examples)

1) Login as the Instance user. If needed CD to your db2 instance directory.
Example:
/opt/tivoli/tsm/db2/instance/
do:
db2start
db2 drop db tsmdb1

2) Do db2ilist to get a list of all the current instance names
Example:
db2ilist
db2stop

3) Change to the root user ID to do the next command (CD back to the instance directory-- Example: /opt/tivoli/tsm/db2/instance/) :
db2idrop <instance name>
Example: If the instance you want to remove is "tsminst1" you would issue:
"db2idrop tsminst1"

4) Delete all files located in the instance directory. Example:
/tsm/<instance_name>

5) Delete all log and DB files for the instance. The location of these volumes was determined at the time of configuration. There is no default location. Example of the directory names:

/tsmdb001
/tsmlog
/tsmarchlog
/tsmlogmirror
/tsmarchlogfailover

Ensure that you are deleting the correct volumes for the instance. If you delete volumes for a different instance than you are removing, that instance will no longer be operational.

6) Verify that /etc/inittab does not have a start tsm server. Remove it if it is there.
You are now ready to run the Tivoli Storage Manager instance configuration again.
