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.

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.

Need to research {$DUPLICATEENABLE ON} further one day, but surely looks useful but is not really documented, not even at the Delphi 2009 documentation where it was introduced: [WayBack] SysUtils.pfIgnoreDupUnits Constant.

Via: [WayBack] MonkeyMixer has just been updated!- I’ve fixed a unit naming collision with Castlia- I’ve added an XE7 project group (which includes both the BPL and… – Simon Stuart – Google+
PS:
A cryptic G+ comment [WayBack] by Uwe Schuster:
DUPLICATEENABLE is old, but since it is something for IDE packages to avoid intersections with user/3rd party packages there is no need for a documentation. I do use it in an IDE package that did use the JCL/JVCL units as well and does another unit with a common name. IIRC I did mention it related to MonkeyMixer.
I think he argues that documentation is both not needed, but the usage of the directive sometimes is. Which somehow feels like a contradiction to me.
PS2: via Stefan Glienke, an error message that is related to this:
---------------------------
Error
---------------------------
Cannot load package 'Package2.' It contains unit 'Whatever', which is also contained in package 'Package1'.
---------------------------
OK
---------------------------

Any good English books similar to the German [WayBack] Agiles Coaching by Judith Andresen [Leanpub PDF/iPad/Kindle]?
Although my German reading is quite OK, it’s not OK enough to fully use this book.
