The picture tricked me into thinking it was a Makefile for Tic-Tac-Toe, but it is in fact a 174 kilobyte makefile for Conways’ game of life which proofs that make macros are Turing complete.
Source: Makefile Assignments are Turing-Complete « null program
via: Abusing POSIX make to implement Conway’s game of life to demonstrate that make macros are Turing complete, even if there are no if and loop macros. – Kristian Köhntopp – Google+
While running on my Mac, the recursivity will make it fail on lack of resources though.
If seen both these:
sleep: Resource temporarily unavailable
and
make[119]: /bin/sh: Resource temporarily unavailable
make[119]: *** wait: No child processes. Stop.
make[119]: *** Waiting for unfinished jobs....
make[119]: *** wait: No child processes. Stop.

A while ago I bumped into applications that write alternating UTF-16 and UTF-8 to files without checking what type of encoding the files were using.
So here are some notes to at least save some of the contents.
TODO: figure out how to strip the BOM.

Since Google has a hard time searching G+: [WayBack] Anyone ever encountered a “[dcc32 Fatal Error] F2084 Internal Error: DBG3133″… – G+ – Jeroen Wiert Pluimers:
Anyone ever encountered a [dcc32 Fatal Error] F2084 Internal Error: DBG3133 in XE8 or newer?
I get it in XE8 version 22.0.19908.869 intermittently on a huge* project when compiling or building.
If it occurs, I have to:
- restart the IDE
- delete all DCU files
- build
Without deleting the DCU files, even a build throws the error after restarting the IDE.
The project never throws an AV while compiling as described in [WayBack] QC #127380: F2084 Internal error AV0B8A47D2-R3E1D3CF8-0 when compiling project unless the IDE runs out of memory (which I now resolved with DDevExtensions).
Every now and then on compile it also throws [dcc32 Fatal Error] F2084 Internal Error: MA1243.
For the other error, the same solution applies: if you don’t, then the next one is a [dcc32 Fatal Error] F2084 Internal Error: DBG3133.
Both errors occur during the Linking stage.

*huge as in that I needed DDevExtensions to work around [WayBack] Is there any tool that clears the Delphi memory overhead when a “build all” switches to the next project in a project group? XE8 constantly runs out of memory… – Jeroen Wiert Pluimers – Google+

ILMerge has all sorts of drawbacks with things like XAML, WPF, NHibernate, dynamically loaded assemblies and reflection.
Jeffrey Richter: Excerpt #2 from CLR via C#, Third Edition | Microsoft Press blog has an interesting approach based on adding a callback to the AppDomain’s ResolveAssembly event with some steps so you can embed assemblies as resources which you then – unlike ILmerge- dynamically resolve.
Those steps require a bit of manual labour which is taken away by MiloszKrajewski/LibZ: LibZ, the alternative to ILMerge.
The repository on github even compresses your assembly resources.

As the pull request had been in the pipeline for almost 2 years, I missed it went through:
Before that, Github would not render parts of reStructuredText files at all it could not fully render them. Now it renders them as raw reStructuredText so at least you can see the content.
Examples:
.. function:: code_to_ast(codeobj)
- Compare the different rendering of these two engines on the same file:
