Aaron Swartz

Entropy Overload – Aaron's death has had a larger effect on me than most things I read about on the web. This death is a little closer than most, and very sad. I had a number of email conversations with him about his blog posts. His articles often annoyed me in their naivete, and what I perceived as their ignorance ...

Moving On

Entropy Overload – An update: I've left Embarcadero Technologies. There's a lot of reasons. I was in the same position for more than six years, but I didn't necessarily want to be pigeonholed as a compiler guy. I was working remotely from London, with all the downsides that remote working entails: relative lack of ...

Motorcycling in the Spanish Pyrenees, and sport-touring tips

Entropy Overload – I've just come back from an excellent holiday: a motorbike trip from London to southern Spain, via Llívia and Andorra. The highlight of the trip was the roads in the Spanish Pyrenees. Many almost abandoned (frequently went for 10 to 30 minutes without seeing another vehicle), mostly good surface, ...

Delphi XE2 compiler performance

Entropy Overload – Delphi XE2 introduced namespaces across the runtime library. This stressed unit name lookup inside the compiler, and led to some severe performance regressions in certain cases. So during the runup to the XE2 release, I fired up a profiler and started investigating. It turns out there were numerous ...

An ugly alternative to interface to object casting

Entropy Overload – I was answering a question on Stack Overflow, but the user didn't have the latest version of Delphi. My answer included converting an interface to an object instance, which is made possible with the as cast on interfaces in recent Delphi versions. But there is another way of doing it, exploiting the ...

Scrolling: Chrome vs Firefox

Entropy Overload – I was using the Chrome browser on my laptop the other day (some browser compat problem). I don't normally use it; Firefox is my preferred browser. I couldn't help but notice how peculiarly laggy it felt to use. It came down to vertical scrolling: this highly common task - for any long article you'll ...

CrashPlan manual installation approach on Nexenta

Entropy Overload – I wrote an earlier post about installing CrashPlan on Nexenta. However, it seems that CrashPlan have changed their Linux installer's modus operandi, and it tries to install a (Linux) JRE of its own. Of course, that won't work; it needs the Nexenta JRE (but I get the whole JDK, as you never know when ...

Non-Delphi: Postmodernism, Transformers: ROTF and Baudriallard

Entropy Overload – The simulacrum is never that which conceals the truth--it is the truth which conceals that there is none. The simulacrum is true. (Baudrillard, Simulacra and Simulation) I've just watched Transformers: Revenge of the Fallen, and it got me thinking. It's perhaps the most post-modern movie I've ...

Virtual method interception

Entropy Overload – Delphi XE has a new type in Rtti.pas called TVirtualMethodInterceptor. It was originally designed for use in DataSnap authentication scenarios (though I don't think it's currently being used there), but of course, making it only work for that would have been quite a limitation. What does it do? ...

Memory leaks, log analysis and Unix command-line tools

Entropy Overload – I had cause recently to tackle a fairly tricky memory leak bug in the Delphi compiler as hosted by the IDE. The test case for the bug was complicated: compiling and running a large portion of the IDE itself. After a compile, subsequent debug runs of the IDE kept on increasing the debugging IDE's ...

Android: Momentum and Apps

Entropy Overload – I'm liking the current momentum behind Android. I'm sure Apple will come out with their new phone soon, and the pendulum will swing a bit, but it's definitely a two horse race, and Apple isn't out of sight, not by a long shot. I got my Nexus One from http://www.google.com/phone a few months ago, to ...

Locations vs Values: using RTTI to work with value types

Entropy Overload – Delphi's Rtti unit is designed in substantial part around TValue, a kind of hold-all record that should be capable of containing almost any Delphi value, along with type information for that value. However, this means that when you're working with value types, such as static arrays and records, ...

Programming font for VS2010

Entropy Overload – So, Visual Studio 2010 shipped. Now I have a problem: what font to use? My old standby, Dina, is a bitmap font so it doesn't work with the WPF text editor in VS2010. Some things I look for in a programming font: High information density - vertical height in particular. For example, I use Dina at ...

CrashPlan for Backup on Nexenta

Entropy Overload – For some time, I've been using cron jobs with rdiff-backup on Cygwin for backups. The cron job runs on a Windows server I have on my home network and iteratively mounts remote Windows shares (if they're present) and runs rdiff-backup over them, with the destination also being local. Then the job ...
