The paths are on a standard Windows 7 x64 machine installed on the C: drive. More recent versions of Windows should use the same place.
I’ve not been able to verify this in a domain situation with roaming profiles and redirected folder paths. If anyone has info on that, please let me know.
Anyway, I’ve made some the constants into a table:
One day I might find time to make this table more complete.
Until then, the code is somewhere around theses pieces of code:

No more issue reporting: tohosokawa/rst-preview-pandoc: reStructuredText preview in Atom using Pandoc
This is a very useful Atom.io package, but it has one big issue: when you close a preview window then re-opening it, the settings are restored to the default -frst -thtml --webtex ones.
As I’m an Atom.io n00b, I need to dig into this another time.
Notes:
I want the defaults to include --standalone --toc --toc-depth=5 or at least --standalone --toc.
For now I’ve hardcoded them.

Learned a few things when modifying https://github.com/gkotian/gautam_linux/blob/master/scripts/colours.sh
Note: `printf` supports emitting `ESC` (ASCII character `\033` aka `27` aka `0x1B`)as `\e` the same way that `echo` does
https://linux.die.net/man/1/printf
https://linux.die.net/man/1/echo
Format strings are at https://linux.die.net/man/3/printf
%-10s means left adjusted (aligned) string of length 10

I was investigating how the colour definitions on my OpenSuSE system actually work internally so I added some extra output: ${TYPE} and ${COLOUR}.

A well worth long rad:
We all recognize emoji. They’ve become the global pop stars of digital communication. But what are they, technically speaking? And what might we learn by taking a closer look at these images, characters, pictographs… whatever they are 🤔 (Thinking Face). We will dig deep to learn about how these thingamajigs work. Please note: Depending on your browser, you may not be able to see all emoji featured in this article (especially the Tifinagh characters). Also, different platforms vary in how they display emoji as well. That’s why the article always provides textual alternatives. Don’t let it discourage you from reading though! Now, let’s start with a seemingly simple question. What are emoji?

Steps:
- Install the Ruby Installer from rubyinstaller.org/downloads
- Add the directory where Ruby got installed to the user PATH (using
"%windir%\System32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables) in my case C:\Ruby23\bin as I installed Ruby 2.3.1
- Install the CA certificates:
- Download https://curl.haxx.se/ca/cacert.pem to the Ruby directory (
C:\Ruby32)
- Add the environment variable
SSL_CERT_FILE with value C:\Ruby23\cacert.pem (again using "%windir%\System32\rundll32.exe" sysdm.cpl,EditEnvironmentVariables).
If you forget step 3, then you get errors like this:
C:\Users\jeroenp>gem install gist
ERROR: Could not find a valid gem 'gist' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
C:\Users\jeroenp>gem update --system
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

Via [WayBack] Graph of programming languages influence poster – nice gift idea for programmers… – This is why I Code – Google+:
A network graph with more than a thousand programming languages connected by influence relations. Highly influential languages like Lisp, Smalltalk, C, Java, Pascal, C++, Haskel or Python are shown as larger circles as compared to languages with little influence on others like PHP or Argh!. / The influence relation data was retrieved from Freebase in 2013. This design available on posters and other products. An awesome gift for programmers who are into digital art. • Also buy this artwork on wall prints, apparel, kids clothes, and more.
[WayBack] “Network Graph of Programming Language Influence – White Background” Posters by ramiro | Redbubble
I wonder how they drew the relations and why certain languages are in certain places.

[WayBack] A colleague and I was just wondering, why was TypInfo.pas not named TypeInfo.pas? The original theory of 8.3 naming convention doesn’t hold as TypInfo i… – Willo “qbitza” van der Merwe – Google+
Because of collision: though hardly documented in the early Delphi days the standard function TypeInfo has been there forever so System.TypeInfo already takes TypeInfo in the global namespace as the System unit is used by default and doesn’t have a namespace prefix.
One more reason to suffix unit names with a word like Unit.
And one more reason to always get a Delphi version with source code for RTL/VCL/…: it’s an invaluable source for not so well documented things.
The TypInfo name was also from an era when some people hadn’t learned yet dat using abbrvtns is a sin. Ken Thompson has learned [WayBack] spell it with an “e” · golang/go@c90d392 but we’re suck with StrPas, StrUtils, IntToStr and others forever like Unix is stuck with creat(2): [WayBack] creat(2): open/possibly create file/device – Linux man page and [WayBack] history – What did Ken Thompson mean when he said, “I’d spell creat with an ‘e’.” – Unix & Linux Stack Exchange.
