A day in the life of...

That's it, I've had enough of Ruby on Rails! I like the rails part, it's a very clever approach, but I really dislike the Ruby part! The final straw occurred yesterday. It's very common in OOP to have the constructor set default values for your object just in case the consumer of your class does not set them. In C# I would do something like this..... public class Post : MyBaseClass { private bool isPost = true; } In Ruby I was trying to achieve this simple behaviour... 01: IsPost is set to true 02: A form is displayed with the default value 03: User changes the value 04: My Post instance is updated with the values from the form I tried to override Initialize() only. def Initialize super is_post = true end Now Post.new(params[:post]) is not reachable for some reason. So in my Post class I did this def Initialize(* params) super(params) is_post = true end The problem here is when I try to initialize the values from the form in my controller class. post = Pos

What a lot of grief! After trying more simple steps on another site (and failing) I eventually managed to get the following steps to work: http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx There were however some changes: 01: Make sure you download TextMate. I kept reading it as TextEdit for some reason, so just be aware of that when "mate ~/.bash_login" wont work. 02: One of the steps tells you to type "make ~/.bash_login". I found that adding the suggested text to that file made no difference when you log out/in or close the Terminal window. This was because a file named "~/.bash_profile" existed. If this file exists then you should modify it instead of the one mentioned in the article. 03: When trying to do "rake db:migrate" I would experience the following error: otherwise you will experience the following error: dyld: NSLinkModule() error dyld: Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib Re

Today I needed to convert an absolute path to a relative path based on a specified base path. E.g. c:\a\b\c -> c:\a\b\c\d\file.txt = d\file.txt c:\a\b\c -> c:\a\file.txt = ..\..\file.txt c:\a\b\c -> c:\a\x\file.txt = ..\..\x\file.txt I am surprised there is nothing in the .NET framework so I had a hunt around and converted the code from the following URL ( http://www.vergentsoftware.com/blogs/ckinsman/default.aspx?date=2006-08-07 ) into C#.... private string RelativePath(string absolutePath, string relativeTo) { string[] absoluteDirectories = absolutePath.Split('\\'); string[] relativeDirectories = relativeTo.Split('\\'); //Get the shortest of the two paths int length = absoluteDirectories.Length < relativeDirectories.Length ? absoluteDirectories.Length : relativeDirectories.Length; //Use to determine where in the loop we exited int lastCommonRoot = -1; int i

I have owned an Acer Ferrari now for approximately 13 months. Previously I had a problem with it freezing randomly. I spent some time trying to reproduce the problem and after a month or two was finally able to reproduce it 100% of the time. I sent my laptop back to Acer armed with exact steps and as a result my laptop was returned to me after only a couple of days. For the past 2-3 months I have been seeing very rare, random resets. Obviously I blamed Windows, as you do :-) Some software I had to convert AVI to MPEG would always reset the laptop, but I just put that down to dodgy software. More recently I noticed that 7-zip would also reset my laptop *only* if I used ULTRA compression on a file larger than 500MB. So I tried Winzip, same problem. I installed Vista and tried both Winzip and 7-zip in there, same problem. With steps to reproduce + proof that it was not the OS I felt I could finally send the laptop back for repair without running the risk of it coming back "No

Someone sent me this on Skype this morning. I think it's really cool, it reminds me of the hardware sprites on the old Commodore 64! 01: Go to any site with lots of images (image search on google is a good one) 02: Once the images appear copy/paste this text into your address bar. javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i<DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(R*x1+i*x2+x3)*x4+x5; DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5 ); void(0);

I've been up quite late working out what I want to cover in the "ECO jump start" document. The trick is to start at a level where the user knows absolutely nothing, and end up where they know enough to decide whether or not they wish to spend some time learning how to use ECO or not. I think I should start off explaining why multi-tiered app development is a good idea; then I think I should go on to creating a package in a DLL; then onto creating a non-persistent WinForm app using that package; then make it persistent; and so on. My problem is that ECO just does so much! I'll paste what I have so far at the bottom of this blog entry to get any feedback. As the list progresses the subjects become more advanced and I am worried that the jump start might actually frighten people off by making them feel overwhelmed. Maybe I should just take it so far and then leave the more advanced items out? Maybe I should just include a section at the end of the document explainin

We use wireless printing through a COM port over BlueTooth. Having BlueTooth on all of the time can contribute towards energy consumption and cause the battery life on the Pocket PC to deplete faster. Now I disable BT when the application starts, and then re-enable it to print and disable it immediately afters. This adds about 1 second to each print job but it should save the battery power. [DllImport("BthUtil.dll")] private static extern int BthGetMode(out BlueToothRadioMode dwMode); [DllImport("BthUtil.dll")] private static extern int BthSetMode(BlueToothRadioMode dwMode); public static BlueToothRadioMode BlueToothRadioMode { get { BlueToothRadioMode result; BthGetMode(out result); return result; } set { if (value != BlueToothRadioMode) BthSetMode(value); } }
