For a simple comma separated list (no quotes), I was expecting a sed script (and indeed it is possible), but tr is more elegant:
Use
trto change , into newlines:
tr , "\n" < list.txt
Source: [WayBack] bash – convert comma separated values into a list of values using shell script – Stack Overflow.

git diff --no-prefix @~
Via various sources:
@~ syntax to get the previous commit
--no-prefix to make the patch svn compatible

Some links for my research (when writing this a few years back, I had not done a lot of SQL Server BLOB work for a while, so I missed a lot of interesting progress).
As of SQL Server 2008, one can use FileStream, which SQL Server installs on an NTFS file system local to the SQL Server instance, but is accessible over the SQL Server API. It benefits from a lot of SQL Server features (including transactional and backup related).
As of SQL Server 2012, FileTable has extended FileStream, which makes it even easier to access the files from Windows applications.
Over the years, FileStream and FileTable has improved a lot.
Some links to get a feel:

Wondering how far Mike Versteeg has gotten in the mean time with the newer versions of Delphi that have come up: [WayBack] I’m having a go at multi monitor high DPI support for my styled 64 bit VCL app, which is still not supported in 10.2. Using Scaled and ScaleBy I can com… – Mike Versteeg – Google+

I wanted to undo a commit, but forgot how to do that.
[WayBack] undo – Can I delete a git commit but keep the changes – Stack Overflow mentions to use
git reset HEAD^
However, on Windows, the ^ caret is an escape character, so there you have to use a ~ tilde instead:
git reset HEAD~
The last one is used in [WayBack] Git – Reset Demystified, and shorthand for
git reset --mixed HEAD~
The differences between --soft, --mixed and --hard is even better explained in [WayBack] The difference between git reset –mixed, –soft and –hard. From http://stackoverflow.com/questions/3528245/whats-the-difference-between-git-reset-mixed-soft-and-hard · GitHub.
In short:
--soft keeps the changes of the undone commit in the index (or staging area)--mixed (default) keeps the changes of the undone commit in the working directory--hard deletes the changes–jeroen

A long while ago, Kristian Köhntopp explained most of the categories in [WayBack] Cynefin framework – Wikipedia using very simple terms, which I have translated like below.
I like the bigger picture below a lot better, as it at least names the “Disorder” middle section which is not in the summary diagram on the right. “Disorder” is exactly the place you want to get and stay out of.
All pictures from WikiMedia.

(“Tickle Me!” “Tickle me, but only until I stop calling!” “Tickle me, but only until I call Stop! And under the blanket, I’m safe!” “Tickle me, but only until I call Stop! And under the blanket, I’m safe! And pulling away the blanket is forbidden!” The son is bound to become a software developer.)
“Obvious” is what a lot of (government) organisations think you and they are in when applying regulations. In reality, “Complex” likely applies best.

Interesting consensus at which is very similar to my experience: [WayBack] I’ve inherited a project and the developer uses lots of interfaces (All good here!). Then when they develop the interfaced classes, the methods from th… – John Kouraklis – Google+
Some go even further and even declare the classes in implementation sections, but for me that gives too much RTTI hassle:
Private types (types in the implementation section of units) do not get qualified names.

Still an interesting question: [WayBack] hash – Why is Git not considered a “block chain”? – Stack Overflow.
With my limited knowledge of both, I think git is a Merkle tree without both a proof of work and consensus system. That would make it the chain part of block chain, and the without bits the block.
How wrong am I?
It seems I still have a lot to learn about Merkle tree related stuff, so on my research list:

On the generics side, I have wrote a few bits in my blog before, often pointing to information by others (many by Stefan Glienke as his skills on this topic are beyond excellent):
And on records:
There are some very good books on Delphi though that dig deeper than the documentation:
