Paired Programming

Have a day off today and just having a quick sit at the pc. Have been doing paired programming at work. Something I have been reading about in Extreme Programming Explained by Kent Beck.

I think it has been working out really well. We took it in turns to write code with one doing the the tests and the other satisfying the tests. Whilst this is undoubtedly good practice I find it strange that it has to get a special mention in programming circles in a way. When I was doing CAD and estimating work we would always sit together, work out the costs, draw it up together and talk about what we were doing ect. I think that was one of the fundamental reasons why I learnt so much about construction in a small space of time.

I definitely think the paired programming gave me a better understanding of how to approach Test Driven Development. Up to now I have approached unit testing the other way round by writing my code and then writing unit tests to cover it. I think that is the main reason why my unit tests did not have full code coverage. The other great thing about paired programming is the confidence it gives you in your code. You have written your tests, they pass and someone has looked over it at the same time. Gives you a very good feeling that nasty defects aren't going to bite you in the ass in 3 months time. I hate that question around the office "who wrote this crap piece of code" and all you can do is close your eyes and say "please don't make it me!"

Motorola MC65

We have a new PDA in town now. As a replacement for the army of MC9000 and MC70s that are in the field and are being discontinued, we now are moving up to the Motorola MC65. I have had the new handheld for about a week now and have been impressed so far. It's a great improvement over the MC70. I have no idea how the numbering system of the Symbol / Motorola devices works. I assume there must be several ranges such as the 50s 60s and 70s.? Anyway the?PDA?has windows mobile 6.5.3, a better touch screen and is faster. Much faster. The skin that has been put on the OS has also applied to our software and I think it makes it look much cooler. We had several problems in adjusting our software so it would work with the new MC65. First was the change in resolution. The MC70 has a much lower resolution than the MC65s and as some of our screens were not using the auto scale settings in the form and some of the buttons on our forms were created at run time rather than design time, this posed

Accessing the UI Thread with Tasks in F#

I have a Windows Forms program written in F# that can deploy a code base to n number of sites at once (you select the sites you would like to deploy to and it goes off and completes a number of tasks (backing up current sites, various unpacking and moving of files etc... ). Once you start it, it begins it's merry journey and begins to update the UI with what has happened. At the moment this method of updating the UI is not pretty because the threads I am doing the work on can't update the UI so I perform some fiendery to make that happen (don't ask). I knew there was a better way using some newer .NET features but I just hadn't got round to having a fiddle yet. I have now found that if you use the built in Task class but break your code up in a nicer way and then chain the tasks together you can then pass the correct context into the task that you want to talk to the UI. Here's a little script to give you a feel for it. You can press the "start" butt

Cab Control

Received another call today from a company interested in my  Cab Control Software . Basically it's taxi management . The software needs a re-write to get it from Windows Forms onto the web. I have great hopes for the software. It really just needs to time and ingenuity pouring into it. I have loads of ideas for it but just have so little time.  It currently has this functionality which I'll need to get across:  Add drivers and Taxis and keep track of their contact details, addresses, licence details, CRB checks and eligibility to work in the UK. Basic account management functions, such as creating a customer account and putting the account on hold.  Add Bookings for drivers and customers Creating reports for customer accounts that could be exported as a CSV file for billing purposes.  Creating reports for drivers to know how many pickups the drivers had made. Query the bookings for enquiries and police check up reports. Provide management tools to check MOT and Service details
