[WayBack] TMS Software | Blog | TEncryptedIniFile: easy to use class for handling app settings with encryption
via: [WayBack] A new blog has been posted:TEncryptedIniFile: easy to use class for handling app settings with encryption – Michael Thuma – Google+
I wonder how that works with encryption algorithms based on thin Delphi wrappers around proven open source encryption libraries.

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

Given a variable I: Integer, some people like Inc(I); others like I := I + 1;.
You might think that part of that discussion nowadays should be multithreading.
In practice this does not matter: the compiler will use the same instructions for both statements.
TL;DR: This might make you think they are always atomic. But that’s not always true, as the below differences show. In addition, it can also depend on your processor archicture.
In the Win32 Delphi Compiler, this is how they look:

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).

Chris Rolliston: +Larry Hengen The Kylix IDE was a fork of the Delphi IDE and used WineLib. It was the applications you built with the Kylix IDE that were QT based.

There is a bit of C++BuilderX history as well (which was based on JBuilder).

How I use Linux to write software for multiple target platforms – Kris Kamil Jacewicz – Google+
WINE has come a long way. Many things do not have a native look and feel, but so do many Delphi FMX or Lazarus LCL applications.
In fact I use quite a few tools (including Mikrotik WinBox) through Wine on Mac OS and it runs a lot more stable than quite a few of the FMX applications I’ve tried and ditched.
So for business applications not requiring a platform specific look and feel this indeed is quite acceptable direction to follow.

At the end of April 2014, Roman Yankovsky started a nice [Wayback] discussion on Google+ trying to get upvotes for [Wayback] QualityCentral Report #: 124402: Compiler bug when comparing chars.
His report basically comes down to that when using Ansi character literals like #255, the compiler treats them as single-byte encoded characters in the current code page of your Windows context, translates them to Unicode, then processes them.
The QC report has been dismissed as “Test Case Error” (within 15 minutes of stating “need more info”) by one of the compiler engineers, directing to the [Wayback] UsingCharacterLiterals section of Delphi in a Unicode World Part III: Unicodifying Your Code where – heaven forbid – they suggest to replace #128 with the Euro-Sign literal.
I disagree, as the issue happens without any hint or warning whatsoever, and causes code that compiles fine in Delphi <= 2007 to fail in subtle ways on Delphi >= 2009.
The compiler should issue a hint or warning when you potentially can screw up. It doesn’t. Not here.
Quite a few knowledgeable Delphi people got involved in the discussion:
