WPF Tutorial | Dependency Properties

Posted by jpluimers on 2015/03/17

Thanks to the answers for .net – What is a dependency property? – Stack Overflow, I came across this really nice WPF Tutorial | Dependency Properties.

It has one of the best explanations on Dependency Properties I’ve ever seen, and it is available online for free (:

And yes, this post is also tagged Delphi, as DSharp provides http://delphisorcery.googlecode.com/svn/trunk/Source/Core/DSharp.Core.DependencyProperty.pas.

So Dependency Properties are not just .NET any more (:

Patch soon and be careful: A Few Thoughts on Cryptographic Engineering: Attack of the week: FREAK (or ‘factoring the NSA for fun and profit’)

Posted by jpluimers on 2015/03/16

Hmm, I missed this earlier. So: watch your TLS stack (OpenSSL and others), then

Patch soon and be careful.

After that read A Few Thoughts on Cryptographic Engineering: Attack of the week: FREAK (or ‘factoring the NSA for fun and profit’).

Thanks Kristian Köhntopp for sharing.

For those doing dates in M/D/Y format: happy Pi Day

Posted by jpluimers on 2015/03/14

I’m more a Pi Approximation Day person.

But for the few that insist on M/D/Y date format: happy Pi Day.

Jan Wildeboer on G+:

“The American date format I invented”, master Yoda exclaimed, “Pi day they now have! But knowing its power they do not.”

Add an account to use Google Play on your device: can take a while to show up.

Posted by jpluimers on 2015/03/13

It might look simple to Add an account to use Google Play on your device – Google Play Help.

But it can take quite a while for your device to show up so you can add My Android Apps – Google Play to it: accounts – My new Android device not showing up in Google Play – Android Enthusiasts Stack Exchange.

OData: a few notes

Posted by jpluimers on 2015/03/12

You can’t keep track of the whole world, so every now and then I bump into something and think “boy I wish I had known about this years ago”.

The OData (Open Data Protocol) standard by Microsoft is such a thing. It allows to communicate data over the internet in a RESTful way using either JSON or AtomPub based XML, standardized by OASIS who has it’s roots in the SGML world (SGML is one of the predecessors of XML).

There is a rich Ecosystem of implementations in many platforms (including .NET, Delphi, Java, PHP, JavaScript, etc) with public reachable Example Services to test with (not surprising there is a NorthWind service).

Here are a few links of stuff I want to dig deeper into it to grasp it better: Read the rest of this entry »

Interesting presentation at EKON 16: MSBuild Inside the Microsoft Build Engine from Sebastian Gingter

Posted by jpluimers on 2015/03/11

I missed EKON 16 as both they and we moved outside the regular conference season.

So I missed this session: EKON 16: MSBuild // Speaker Deck that has these GitHub source examples: gingters/EKON16_MSBuild.

Thanks Sebastian Gingter for pointing me at this!

msbuild is used by both Visual Studio and Delphi for building projects, and this session gave me some good ideas to improve the Continuous Integration projects I already had into place.

On the research list; XP update failures

Posted by jpluimers on 2015/03/09

I know, I know. But the Olympus P-400 still requires XP.

So here it goes: failed updates.

Update for Microsoft Visual C++ 2012 Update 4 Redistributable Package ([Wayback] KB3032622)
Windows Malicious Software Removal Tool – February 2015 ([Wayback] KB890830)

The Microsoft web update fails to load at all with error [Wayback] 0x80248015, which is logical as officially there is not support any more.

http://www.update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us

Luckily the Windows web update still works: http://windowsupdate.microsoft.com/windowsupdate/v6/default.aspx?ln=en-us

This time the update got simply resolved by rebooting. Hopefully that solved it for good.
