This is the Remoting exception IIS was consistently giving me after a deep search. The search was returning some mammoth blob's and failing after a few minutes.

I thought it might be an IIS error, sure enough after firing up TCPTrace and sniffing around, I found

So rather than throwing a relevant HTTP response code, we get a html error page that can't be serialized. Hopefully this saves fellow insane technologists a little time.

Returning lambda's from a ternary in C#

In the midst of some mad refactoring I came across something similar to the following snippet:

 1 if (count == 0)
 2   choice.Finish = result => { return; };
 3 else
 4   choice.Finish = result => { letter.MailMerge(result); };

Looked like a decent candidate for refactoring with a ternary / conditional operator:

 7 choice.Finish = (count == 0) ? result => { return; }
 8                              : result => { letter.MailMerge(result); };

Type of conditional expression cannot be determined because there is no implicit conversion between 'lambda expression' and 'lambda expression'

Hold your horses, say what?

For some reason the only way to fool it through the compiler is to cast one of the expressions (it doesn't seem to matter which one) to the expected return type.

11 choice.Finish = (count == 0) ? (TypeDelegate<int>) (result => { return; })
12                              : result => { letter.MailMerge(result); };

Go figure!

VIM on OpenVMS

This is a note to future Dan and anyone else that may have file permission problems when running VIM on OpenVMS.

Define this logical:

Dan$ define DECC$ACL_ACCESS_CHECK ENABLE

Apparently when disabled the access function only checks the UIC protection and not the OpenVMS ACL's.

There are all other kinds of goodies here

SVN 1.5.1 / Ruby bindings on Windows

Rather than messing around with compiling swig bindings etc:

1. Download the ruby bindings from the svn site: (http://subversion.tigris.org/files/documents/15/43245/svn-win32-1.5.1_rb.zip)


2. From the zip - copy ruby\lib\svn into c:\ruby\lib\ruby\site_ruby\1.8\svn


3. From the zip – copy ruby\ext\svn\ext into c:\ruby\lib\ruby\site_ruby\1.8\svn\ext


4. copy libeay32.dll and ssleay32.dll from your subversion 1.5 directory into c:\ruby\bin


5. run irb and test with: require ‘svn/core’

Why?

css:

.mainMenuHeader {color:#FFFFFF;}
.mainMenuHeader:hover {color:#F26540;}

xaml:

<Style x:Key="mainMenuHeader">

  <Style.Triggers>
    <Trigger Property="Control.IsMouseOver" Value="True">
      <Setter Property="Control.Foreground" Value="#F26540" />

Home Town Hero - That's How I Know

Hopping back in the time machine to 2002 a slightly rockin' album came out - Home Town Hero - Self Titled. It sounds a little grungy like The Exies and a little power-poppy like Rooney.

They had some minor successes opening for STP, Incubus and Weezer. Since then, they have completely fallen off the radar. Apparently there was some unpleasantness with their record label and they are now back under the moniker: Under the Influence of Giants. I gave their new LP a listen, i just couldn't get into it. I think it has validly been classified as disco-rock :)

Nick and I were giving it a thrash this week, so as an ode to the good old days I tabbed out the secret/bonus/acoustico track, as it appears no-one else has.

It ain't the most complicated tune on the planet but stay tuned for Niccolò Paganini's 24th Caprice next week :)

bon appétit!

Fixing the Teac HDB820 C.100 Error

The other day I mentioned I was feeling slightly hot and bothered. Well, so was my Teac HDB820.

I woke up this morning and I was greeted by the dreaded C.100 error. I tried turning it on and off, no go. I´ve had it for about 2 years so warranty was no option. On cracking it open one of the 1000uF 16V capacitors had a slight eruption. There are 3 in total and with the weather we´ve been having; i´m not suprised it gave up.

After I got home from work I ducked into DSE and grabbed 3 of these chunky bastards - 1000 uF 35 WV caps. I then whipped out the soldering iron (i knew doing year 11 electronics would pay off one day) and 10 minutes later I was back in sweet sweet HD heaven.
