A nice article [Archive.is] What is thread safety anyway? with a kind reference to the Deadlock Empire translation from C# to Delphi that I made.
In any language, multi-threading is hard, so I really love the quote below:
[WayBack] Multithreading can be hard to do right. The most common point of failure is assuming some code is thread safe when it actually is not... – Dalija Prasnikar – Google+
It reminded me of an old one:
A programmer had a problem. He thought to himself, “I know, I’ll solve it with threads!”. has Now problems. two he

Mads Torgersen shares future thinking of a fast-moving major programming language, C#. Torgersen discusses pattern matching, type classes, discriminated unions and much more.

LINQ is certainly extraordinarily useful. It brings the power of query expressions to C#, allowing an easy way of getting the data you need from a variety of data sources. Up to now, there hasn’t been a VS debugger for LINQ that gives you the means to visualise the data at every point in the chain. Michael Sorens, a keen LINQ user, describes a third-party tool that now promises to make using LINQ something we can all participate in.…

Ah, C. The best lingua franca we have… because we have no other lingua francas. Linguae franca. Surgeons general? C is fairly old — 44 years, now! — and comes from a time when there were possibly more architectures than programming languages. It works well for what it is, and what it is is a relatively simple layer of indirection atop assembly. Alas, the popularity of C has led to a number of programming languages’ taking significant cues from its design, and parts of its design are… slightly questionable. I’ve gone through some common features that probably should’ve stayed in C and my justification for saying so. The features are listed in rough order from (I hope) least to most controversial. The idea is that C fans will give up when I call it “weakly typed” and not even get to the part where I rag on braces. Wait, crap, I gave it away.

I mentioned Asbjørn Heid on wiert.me before. While prepping for the Deadlock Empire workshop at EKON20, I needed a Delphi equivalent for the .NET [Way: Barrier Class (System.Threading)
The game uses that in level deadlockempire.github.io/#H4-Barrier [WayBack].
Edwin van der Kraan found the ThreadBarrier/ThreadBarrier.pas at master · lordcrc/ThreadBarrier implementation via [WayBack] Is there a way to create memory barriers in Delphi? Something like .NET’s System.Threading.Barrier class, java.util.concurrent.CyclicBarrier… – Horácio Filho – Google+
It’s from Asbjoørn who is known as lordcrc on GitHub. Cool stuff!
So yes, there is a Delphi version of If you thought you could do multi-threading, then play “The Deadlock Empire” games. You can find it at https://deadlockempire.4delphi.com/ There are two deadlockempire implementations there:
The workshop was great fun!
This is about a web game focussing on the concurrency issues in multi-threading environments. By the conference there will be a Delphi version of it. At the workshop we will play each round interactively: all attendees play the round followed by a short discussion. This is about collective learning, so the speakers will probably learn… Read More

It might sound like I’m late in the game, but remember that blog posts are usually scheduled like a year in advance.
So I found out a long time ago (I think it’s Matthijs ter Woord who attended me) about Visual Studio Code.
At the start [WayBack] it was more limited (from memory something like C#, TypeScript, Java Script languages and frameworks Node.js and ASP.NET 5) than my other development environments but now it’s much richer.
It’s based on the Electron framework which I kew from the Atom.io editor and Koush‘s framework Electron Chrome that wraps Chrome Apps in Electron so he ensured Vysor would live after Google will kill Chrome Apps.
Oh it’s free and runs multi-platform which I like a lot (and was one of the reasons to start using Atom.io): Mac OS X, Windows and Linux are supported.
So here are a few links to get started:
I got reminded a while back** that it is now supported by OmniPascal [WayBack] which I like because of my Turbo Pascal -> VAX/VMS -> csh -> Delphi -> AS/400 -> .NET background.
Like Visual Studio Code is updated often, the Omni Pascal blog [WayBack] shows regular updates and I like it a lot better than the Lazarus IDE (I’m not a visual RAD person: I’m a RAD code person) especially the refactorings.
So start playing with it. I will post more about my Visual Studio Code experience in due time.

There is so much great stuff in reStructuredText, take for instance [WayBack] reStructuredText Interpreted Text Roles where basically can create your own role (for instance :csharp: or :delphi: roles based on :code: for syntax-highlighted code blocks given the right syntax highlighters).
I got there via this great piece by[WayBack] Chris who answered [WayBack] Inline code highlighting in reStructuredText – Stack Overflow:
Having looked into this some more I stumbled upon the document reStructuredText Interpreted Text Roles. From this document:
Interpreted text uses backquotes (`) around the text. An explicit role marker may optionally appear before or after the text, delimited with colons. For example:
This is `interpreted text` using the default role.
This is :title:`interpreted text` using an explicit role.
It seems that there is a code role, so you can simply type
:code:`a = b + c`
to render an inline code block. To get syntax highlighting you can define a custom role. For example
.. role:: bash(code)
:language: bash
which you can then use like so:
Here is some awesome bash code :bash:`a = b + c`.
Note, the document I link to makes no mention of the version of docutils to which it refers. The code role is not available in docutils 0.8.1 (which is the only version I have to test against).
