Do NOT delete the folder "C:\ProgramData\Package Cache".
But you can move it to another storage and link to it so when you change/update/remove Visual Studio 2012, you still have access to it.

Since they’re hard to find on-line, and sometimes I need them when not having access to my collective browser or email history:

To get going for my special case, I watched some sample videos (which I did get to work in Internet Explorer but not in Chrome forty-something):
I needed it to do some profiling comparisons of services running under different configurations.

I needed to find the symlinks in /etc pointing to directories and know both the name and place they point to.

For my link list as one day I will surely need a tool like this:

Always handy to have at hand as the git-reset documentation is toooooo long:
Undo a commit and redo
$ git commit ... (1) $ git reset --soft HEAD~1 (2) << edit files as necessary >> (3) $ git add .... (4) $ git commit -c ORIG_HEAD (5)
- This is what you want to undo
- This is most often done when you remembered what you just committed is incomplete, or you misspelled your commit message1, or both. Leaves working tree as it was before “commit”.
- Make corrections to working tree files.
- Stage changes for commit.
- Commit the changes, reusing the old commit message.
resetcopied the old head to.git/ORIG_HEAD;commitwith-c ORIG_HEADwill open an editor, which initially contains the log message from the old commit and allows you to edit it. If you do not need to edit the message, you could use the-Coption instead.

Thanks Adrian W for providing the below example in your answer about obtaining GLUE record information for a domain.
It is an excellent showcase for the $IFS Internal Field Separator available in any nx shell.
In this case it is used to get the TLD (top-level domain) from the domain name specified at the command-line.
After that, it obtains the name servers for that TLD, and queries the glue records there, both using dig.
Here is a little shell script which implements Alnitak’s answer:
#!/bin/sh S=${IFS} IFS=. for P in $1; do TLD=${P} done IFS=${S} echo "TLD: ${TLD}" DNSLIST=$(dig +short ${TLD}. NS) for DNS in ${DNSLIST}; do echo "Checking ${DNS}" dig +norec +nocomments +noquestion +nostats +nocmd @${DNS} $1 NS donePass the name of the domain as parameter:
./checkgluerecords.sh example.org

There are so many ways to view the last Git commit on the command-line.
On the one hand this shows the versatility of Git. On the other hand there are so many trees in the forrest, that it is hard for people to find how to do simple things.
The one I like most is this:
git show --name-status --oneline
Others:
git log --name-status HEAD^..HEAD
git log -1
git show
git diff
git show --name-status
git log --stat -n 1

The background here was a quick project at a client where many .dproj files were in the same directory, but they suffered from conditional define differences. Which meant that even if they were all using the DEBUG configuration, some defines in the .dproj directories were different therefore poisoning shared .DCU files (as Delphi does not automatically rebuild them when the sources have not changed even though the IDE switched to a new project).
There was no quick possibility to reorganise the project structure (a combination of a version system history being problematic and potentially lots of relative path references in the .dproj and .dpr files could still be broken) so I wanted different “Unit Output Directories” for each project preferably using non-hardcoded project name.
So I tried putting $(PROJECTNAME) in a “Unit Output Directory”. But unlike build-events – where that one has a value – in the Directory it hadn’t.
To cut things short, Uwe Raabe did some spelunking in the .dproj file and found that $(SanitizedProjectName) was recognised so I switched to .\$(Platform)\$(Config)\$(SanitizedProjectName).
Putting it in the OutputDirectory (where your .EXE gets emited) fails for most part. Yes, the .EXE gets put in the right directory. No, the debugger cannot find it as it thinks it needs to use %SanitizedProjectName%. No for TestInsight: it cannot find the EXE either because of the % expansion.
Based on SanitizedProjectName, I did some more spelunking coming with the below list. Remember though:
Only tested for
Win32applications for Delphi XE8
I assembled the list by doing a quick sed on a Delphi XE8 Win32 .dproj file transforming all XML element names to $() form then running it through a uniq like script. After that I added each of them in a “Unit Output Directory” prepended with .\_\ (well I cheated a bit, I did them in groups separated by a back-slash and went back to single items in case of failures. A kind of ‘binary search’).
Ensure the ones you use, are defined before you use them. For example: the definition of SanitizedProjectName need to be in the .dproj file before actually using SanitizedProjectName.
These expand to empty strings:

Verily, they did make support for the Internet of Things.
As always, brilliant writing. For instance:
