Wow: I feel like having lived under a stone for 8 years, as RosettaCode has been alive since it was founded in 2007 by Mike Mol.
The idea is that you solve a task and learn from that, or learn by seeing how others have solved tasks or draft tasks.
So in a sense it is similar to the Rosetta stone: it has different languages phrasing the same tasks.
There are already a whole bunch of languages on RosettaCode (of which a few are in the categories below), and you can even suggest or add your own languages.
When you want to solve tasks, be sure to look at the list unimplemented tasks by language that leads to automatic reports by language (for instance two of the languages I use most often: C# and Delphi).
I’m sure there are lots of programming chrestomathy sites, even beyond the ones, and it feels very similar to programming kata sites.

This used to be a great Delphi-only feature that I missed in Visual Studio, but I found the downloadable free extension Favorite Documents extension.
It is a by Sergey Vlasov, who has a whole bunch of free and paid Visual Studio add-ins, extensions and tools.

Once every while you still do WinForms work, and bump into something you hadn’t bumped into before.
This time it was trying to set ForeColor = Color.Red on a ReadOnly TextBox for displaying error messages:
- Using a TextBox means the user can still copy the text to the clipboard.
- Using a Red foreground draws enough attention (it’s was an app with a really busy user interface).
When setting a TextBox from ReadOnly = false to true sets the BackColor from SystemColors.Window (usually white) to SystemColors.Control (usually light grey), and leaves the ForeColor to SystemColors.WindowText (usually black).
Setting ForeColor = Color.Red (funny there is a plural in SystemColors but not in Color) it doesn’t display it as such:
To my surprise, the TextBox had ReadOnly text (you could copy, but not modify it), which showed with a a grey (SystemColors.Control) BackColor and a black (SystemColors.WindowText) ForeColor: the defaults for a ReadOnly TextBox, not using my ForeColor = Color.Red;
I vaguely remembered there was some odd way of solving this, but since I hadn’t written a blog article about it back then (somewhere around .NET 1.x or 2.0 I didn’t have a blog yet), I was glad that Cheetah posted this answer on StackOverflow: Read the rest of this entry »

If you are into serious software development, then this is a 75 minute PodCast you must listen to: Episode 215: Gang of Four – 20 Years Later : Software Engineering Radio.
Abstract
Johannes Thönes talks with Erich Gamma, Ralph Johnson and Richard Helm from the Gang of Four about the 20th anniversary of their book Design Patterns. They discuss the following topics: the definition of a design pattern and each guest’s favorite design pattern; the origins of the book in architecture workshops; the writing of the book together with the community; the rock-star feeling at the release of the book at OOPSLA conference; the influence of the book on the industry; the evolution of the Observer pattern; and new patterns since the book was released. The interview closes with each guest talking about their current projects.
What I liked
Of course I enjoyed the history of the Gang of Four (and am still sad that John Vlissides passed away).

Earlie this month, I wrote a review about Delphi Cookbook.
Well: as of last thursday, you can get that for USD 5 (or EUR 4.80, so better get yourself a USA account: just ensure your address is in the USA).
Heck: until januari 6th, you can get any eBook or Video on Packt for USD 5.
Note there is even an x-Mas countdown on the way (with each day a free book that is readable/downloadable for 24 hours).
There’s over 2500+ books to choose from, so I’m grabbing this chance to learn a few things on OpenCV, Scala, and PowerShell.

I had some excessive CPU usage (30% on a 4-core system) inside WheaAttemptPhysicalPageOffline when using an Intel HD graphics 2500 GPU.
At first I thought I needed to convince IT to update the drivers: Intel HD graphics causing high CPU utilization | Intel Communities.
Then I closed all Visual Studio 2013 instances and the CPU usage went to normal.
So I’m suspecting a WPF issue somewhere.

Last year’s summer, I posted some .NET/C#: some starting posts on the yield keyword and mentioned that async and await might be the most complicated compiler transform.
So here are some posts to learn more about async and await: Read the rest of this entry »
