A great table with comparison of various constructs in Lightweight Markup: Markdown, reStructuredText, MediaWiki, AsciiDoc, Org-mode – Hyperpolyglot
It works much better than the examples in Lightweight markup language – Wikipedia, the free encyclopedia (which does include more languages).
As I’ve switched to “all source – including docs – should be in text format” years ago, I’m a heavy markdown user, but also use reStructuredText, so this table is of great help.
Reminder to self: reStructuredText does not support strikethrough out of the box.

Not sure what the cause and effect are, but various people are having issues running Delphi versions on Windows 10 Creators update. Debugging takes an exceptional long time to load the debuggee.
According to Marco Cantu, it is not limited to Delphi:
“It looks like a change in libraries code relocation, and it affects all debuggers — not just ours.”
A roll-back does make them work again but … there is only a very limited time frame to roll back from Windows 10 Creators update (think days, not weeks).
So for now: if you use Delphi do not install the Windows 10 Creators update unless you:
- can revert back to a full system backup
- can roll back in time
Examples:
The the last link cannot be archived, not is publicly accessible, I’ve quoted some parts:
The debugger goes haywire for everyone in our organization with Creators and Tokyo/Berlin. Reverting to Windows Anniversary brings back the sanity.
Debugger problems with Tokyo/Berlin and Creators:
- App takes a long time to load with modules loading and unloading and re-loading many times
- IDE freezes
- Memory consumption of bds.exe explodes, sometimes (> 3GB)
I will attached before and after screenshots showing how modules load and unload and re-load with Windows 10 Creators.
I presume these problems have the same root cause(s) than those in https://forums.embarcadero.com/thread.jspa?messageID=884382
Note that Microsoft is still fledging out issues in Windows 10 Creators Upgrade despite pushing it to more and more Windows 10 machines: [WayBack] Windows 10 Creators Update rollout: First phase update – Windows Experience BlogWindows Experience Blog

Sometimes msbuild will throw an error like this for an x86 project:
"C:\Users\Developer\Versioned\libssh2\build\libssh2.sln" (default target) (1) ->
(ValidateSolutionConfiguration target) ->
C:\Users\Developer\Versioned\libssh2\build\libssh2.sln.metaproj : error MSB4126: The specified solution configuration "Debug|X64" is invalid. Please specify a valid solution configuration using the Configuration and Platform properties
form="Any CPU") or leave those properties blank to use the default solution configuration. [C:\Users\Developer\Versioned\libssh2\build\libssh2.sln]
Cause:
vsvars64.bat will set the environment variable Platform=x64 but vsvars32.bat will not empty this environment variable.
Easiest is to run set Platform= then run vsvars32.bat.
Adopted from MSBuild creating an x64 solution configuration via sln.metaproj – Stack Overflow [WayBack]:
If you are running this in the Visual Studio x64 command window it will set an environment variable Platform=x64 that will be used by msbuild. You can verify this by running echo in the command prompt you are using.
echo %platform%
So you will need to override the default when using x64 cmd, or run from the x86 cmd.

To get to the compare view, append /compare to your repository’s path.
This brings you the basic comparison interface which is very flexible: just enter a branch, tag or history marker in the dropdowns for base and compare.
Examples from the user docs:

The story isn’t a catch-22, but it is still fun to read:
SSH port is 22. The history of how I (Tatu Ylonen) got it. How to configure it through firewalls and iptables.
It also shows how agile the Internet was back then.

Nice find:
Stefan Glienke+4
Look into the initialization block of FMX.Dialogs. The call to ActivateClassGroup(TFmxObject); turns off all the TRegGroups that don’t contain at least one type that inherits from TFmxObject which also happens to be the group that you register your form class to. GetClass then ignores such groups.
I don’t have the slightest idea what the intention behind all that code is but it certainly is one of the reasons why you cannot mix FMX and VCL officially.
In response to:
I have an VCL application. I need to register some form classes at run time. This is done in the form’s unit implementation section :
Initialization
If GetClass(‘TfmConnectiondialog’) = Nil Then
Classes.RegisterClass(TfmConnectiondialog);
Suddenly my class wasn’t registered anymore. GetClass(‘TfmConnectiondialog’) was always nil and Classes.RegisterClass had no effects.
After some long search, I’ve found that I’ve inadvertently added an FMX.Forms in one of my unit. This was the culprit. Replacing FMX.Forms with VCL.Forms solved my problem.
Behaviour is really strange, why Classes.RegisterClass didn’t throw any exception ? Is this a “Bug” or is this “as expected” ?

Printing Markdown with GitPrint
Simply view any Markdown file on GitHub, then in your URL bar replace the github.com part of the URL with gitprint.com — your markdown file will be rendered to a beautiful, printable PDF.
Try an example https://gitprint.com/jquery/jquery/blob/master/README.md
Every once in a while I feel like I’ve been living under a stone for years. Today is such a day as gitprint has been around since 2014 and I only noticed it until now.
It’s cool as it prints any github page (including Markdown, RestructuredText, etc) as a PDF file.

Geek pr0n on the C64:
Making a demo in just 256 bytes would be a formidable challenge regardless of platform. A Mind Is Born is my attempt to do it on the Commodore 64. In the absence of an actual 256-byte compo, it was submitted to the Oldskool 4K Intro compo at [WayBack] Revision 2017, where it ended up on 1st place.
