Windows Kernel object names are optional. Don’t give them a name unless you intend them to be shared. (via: The Old New Thing)

Very interesting:

Kernel object names are optional. Don’t give them a name unless you intend them to be shared.

Scala programming language and Venkat Subramaniam videos

Posted by jpluimers on 2015/06/30

A long while ago, someone (it was too long ago, so I sincerely forgot who, it probably was in the JBuilder era) told me that I should try out Ruby and Scala.

I did take a short look at Ruby back then, but since Ruby was so focussed on Web Development, and my heart really wasn’t there, postponed it to the times that the Web would be hot for me.

Then I should have taken a look at Scala (which compiles to Java bytecode), but since I abandoned Java (JBuilder wasn’t nice, Java programming was slow and modern IDEs like IntelliJ IDEA and Eclipse weren’t there yet).

Now that I’ve done truckloads of work in the .NET and Delphi world (including domain specific languages and Pascal based products), I bumped into these Scala videos by Venkat Subramaniam:

Boy, I should have taken a look earlier: like Delphi and C# it is a statically typed compiled language, but it is on steroids.

Yes, I know it leans on the Java bytecode as a run-time platform, but so does the Android SDK as one of the Java Platforms. Contrary Ruby, which with IronRuby runs on .NET and RubyMotion runs Mac and iOS, Scala does not run on the .NET platform any more.

Given the witty way of presenting I’m surely going to follow Venkat Subramaniam and watch some of his other videos too.

Shortly after watching the above I bumped into this video by Steve Yegge (Google): Dynamic Languages Strike Back – YouTube.

20 years ago today: Here’s a nickel kid. Go buy yourself a real computer.

Posted by jpluimers on 2015/06/24

An eternal Dilbert strip that is based on the tiny Here’s a nickel kid. Go buy yourself a real computer fragment from single.h:

#if _FP_W_TYPE_SIZE < 32
#error "Here's a nickel kid. Go buy yourself a real computer."
#endif

Aspect Oriented Programming in Delphi

Posted by jpluimers on 2015/06/24

I’ve been doing Aspect Oriented Programming (AOP) in .NET for a long while, mostly using PostSharp LAOS as that was the first AOP .NET library I encountered (5 years ago it became PostSharp 2.0, now it is already at its 10th anniversary!).

AOP allows you to perform separate of concerns (SoC) in your application, especially in the area of cross-cutting concerns like for instance logging, authorization, monitoring, etc.

It took a while in Delphi to allow for AOP, but the TVirtualMethodInterceptor (that introduced in Delphi 2010) can be used to do AOP (only for Virtual Methods, which is still way better than having no AOP at all).

The code requires a lot of manual labor. so I was glad that DSharp (a great library by Stefan Glienke – one of the leading Spring4D contributors) contains a nice wrapper around TVirtualMethodInterceptor so you can use AOP in an attribute based fashion.

Nick Hodges recorded a good introductory video on AOP in Delphi with slides and demo code:

Note that besides DSharp, also MeAOP and Infra provided support for AOP in Delphi, but these haven’t had updates since 2010.

Yahoo Pipes Blog – Pipes End-of-life Announcement

Posted by jpluimers on 2015/06/05

Too bad. It was fun while it lasted: Yahoo Pipes Blog – Pipes End-of-life Announcement (thanks to Dennis for reporting this).

Which means that in a few months time, this pipe will be gone: Delphi Pipe – Delphi related RSS feed running on Yahoo Pipes – via twm’s blog « The Wiert Corner – irregular stream of stuff.

There is an alternative: http://www.beginend.net/

That redirects to https://www.beginend.net/ which works fine from home, but at the client for I the McAfee gateway currently cannot handshake to it:

Host: http://www.beginend.net

Reason: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

Anyone who knows what that is?
