I got an email on Friday from a German guy called Bernard. He uses my wiki note-taking app that I wrote to play with the Windows Mobile SDK (that in itself was a surprise!).

He asked if I’d add support for accented characters to it, as he (unsurprisingly, being German!) wanted to use German characters in his notes. That was an easy enough fix – just add a lookup table to the wiki markup parser which replaces characters with their HTML code equivalent.

Hurrah – I could feel suitably smug for making it a little less English-centric.

A guy called Alex brought me back down to earth on Saturday morning with an email pointing out that when he uses my wiki note-taking app (wow – how many people are using this??), it displays the wrong Chinese characters in ‘View’ mode to the ones he enters in ‘Edit’ mode. Chinese? Eeek… this isn’t something I knew about.

Most die-hard command-line fans tend to agree that the Windows Command Prompt isn’t great. When you consider how old it is, it isn’t all that powerful. This isn’t the end of the world, as there is always cygwin.

But now Microsoft have released their new command prompt PowerShell. I tried downloading it this evening, and so far, I really like it.

This might not be earth-shatteringly new to those who have seen my code before, but I was a little surprised. 🙂

A C program that I wrote a little while ago (and has previously worked fine on Windows, Linux, Solaris and HP) failed horribly on AIX. A little digging showed that I had written:

char* thisIsSupposedToBeAString[256];

I guess that at the time I wrote it (presumably early in the morning, and caffeine-fuelled) I had a string (char thisIsSupposedToBeAString[256];) and wanted a pointer to it, so went back and stuck a * on it without thinking.

As I’ve started storing all of my project work and GTD notes in my Wiki program, I thought it might be a good idea to take regular backups of the text files it uses for data. And being a geek, I thought I’d automate it. 🙂

@ECHO OFF
REM this makes the batch file less noisy - dont 
REM  output commands to screen


REM limit scope for environment variables created here 
REM   to within this batch file only
SETLOCAL


REM make a note of where the current directory is 
REM   so we can go back there afterwards
REM  (useful when running this batch file manually)
set DIR_TO_RESTORE=%CD%


REM run the   'date /t' command
REM   this outputs in the format:
REM   19/11/2006
REM  (probably different for people with non-UK regional
REM   settings)


REM Using for to look at bits of date individually...

REM this gives us a numeric date - in the format yyyyMMdd

I read a couple of weeks ago about Google acknowledging that they’d released too many products, and deciding to focus on developing features for existing products where possible in future. With this in mind, this evening’s idea for Windows Mobile development is an extension to one of the core applications rather than a new application.

‘Email Triage’ is my extension to Pocket Outlook. Pocket Outlook comes with Tasks, Calendar and Messaging (for emails, SMS, and MMS). Despite the way the ‘Pocket Outlook’ sounds, these are more or less separate applications, which don’t interact other than sharing a common database to store information. As a user, the common name feels like mainly a branding thing. So I thought I’d try bringing them a bit closer together.

My Thinkpad is full of random bits and pieces of unfinished code. Typically, I’ll have an idea for something, and do enough of it to convince myself that I’d be able to do it. Something like a coding magpie, I then get distracted by something else and never get round to going back and finishing it. Given that, I’m all the more impressed that I got round to finishing the Windows Mobile wiki-based notetaking app that I started last Sunday.

I know about a few little kinks in the code, and I’m sure there are many more. So maybe not completely finished, but it’s in a state where I can start using it, and have made it available to a few other people to use it as well.

Wrote another Windows Mobile app tonight – this time I even tried it out on my phone and not just the emulator!

The idea of this one is an alternative to the built-in Windows Mobile “Notes” application. Instead of single ‘post-it-style’ notes, the idea is to use a wiki approach – a personal wiki, entirely hosted on the PDA. (Partly because it is quicker to use local files, but mainly because I’m too skint to pay the mobile data fees to access an online wiki :-))

I prefer the wiki approach to note-taking – mainly for the quick and easy formatting and the hyperlinks between pages. I’ve used something similar before on Palm OS for a couple of years now – ‘NoteStudio‘ by DogMelon. This is a brilliant app, which I really miss since moving to Windows Mobile as my main PDA. (There has been some talk of a Windows Mobile for a while now, but this is looking a little like vaporware).

When I saw that the .NET compact framework included a web browser widget, I thought I’d see how hard it would be to knock together a wiki tool tonight.
