I've been using SubVersion for a while, several years infact, I use VisualSVN on my server and TortoiseSVN on my machines. Until recently I had never experienced any problems or glitches with it. However at some point within the last two months one of my main repositories started playing up. It's the only repository I have ever branched. The problem occurred when after working on a branch for several months I decided it was time to merge it back into the head. However when I tried to use the merge function and take the branch into the head I was given the following error message: [branch] is not a child of repository root URL [trunk] I tried several attempts at trying to do this, rechecking out the branch and trunk in case they were corrupt but to no avail. I then decided to try creating a new branch to see if the repository was totally broken and I indeed got an error. Repository moved permanently to [svn server address] please relocate; So it looked liked the reopsitory was b...

This weekend I had to reinstall a driver for a laptop touch pad. I went to the Sony site and got the driver, it came in a zip file and looked pretty standard. A load of driver files and an install file. It install all OK and the touchpad started to have its scroll options, however then I rebooted and found each time the laptop started up Windows Vista kept asking to confirm I wanted to run the programs, "This file came from another computer and might be blocked to help protect this computer". Straight away I thought it had to be the file was blocked from running as it came from a download. I went to the files unblocked them all, clicked apply and rebooted again only to find it happen again. Just to ensure I hadn't forgotten to click apply I tried this again only to find the same thing. After Googling for the issue I found the issue was that the installer had simply copied the drivers and files. This meant that the NTFS information was also copied, this information contain...

In this day and age it is very uncommon to not use the internet to research or solve problems. Our reliance on printed reference books and even reference sites has dwindled massively. As developers, especially budding developers, we often just Google our problems, in fact I think most of our senior dev's often say to us "have you Googled it?" When asked about something. Now googling things of course has changed our industry, we can often solve problems or get good starting points within seconds. This on its own is not a bad thing, we google we get the results and we crack on. The problem however is when you pick the first item or a random article and use what someone else has written as FACT. The problem with our "Google" culture, this applys to more than programming, is that we often don't filter what we read. We suffer from fps, first page symdrom. If its on the first page of our results it has to be correct. Sadly though all too often the actual blogs or...

First things first, ignore the random title for this post, it does have a meaning and it's the best I could up with ;) The other evening I was hitting some downtime and rather than carry on playing FarCry 2 I decided I'd write a quick FCKEditor plugin which I've been meaning to write for a while. By default the editor comes with functionality to insert flash files into your content which works well however I wanted to have a way to only insert online videos from Flickr, Vimeo or YouTube. To insert these I was having to manually go into source view, paste in the embed code etc. A chore and a heartache. So enough was enough and I banged together a quick plugin that would take a YouTube Embed URL and then insert the appropiate embed HTML for it. This was actually quite simple. I worked out there was four main steps, 1. Extract the video ID from the URL 2. Create suitable embed markup and insert into the editor 3. Create a preview video so you can ensure it works before click...

Content Management Systems are great, they allow the average Joe to have a great level of control over their website. Gone are the days of clients asking for static pages to be amended, we live in the database powered give the power of editing and updating content to the client Our clients get to use Rich Text Editors like FCKEditor. They look and feel just like Microsoft Word, they can play with text, upload images, resize them simply by dragging them and are very often really happy. However this often comes at a cost. Most RTE's by default simply resize images by sticking on the HTML img attributes height and width. As many people are aware this doesn't actually resize the image, it just simply tells the browser take this massive image and render it smaller. The end user still has to download the huge image, I have seen on some sites 2000px x 1200px images being downloaded and then only shown at 250px x 120px!, which can take a while to load dependant their internet connectio...

Today I had to resolve an issue where in different browsers the filed dynamically generated download worked very differently / at all The setup, we had an xml file with a custom extension, say .mj, which was being served up by ASP. The HTTP Header had a content disposition header and a response type set. Response.AddHeader "Content-Disposition", "attachment; filename=""our file.mj""" Response.ContentType = "text/xml" This worked fine in Internet Explorer, the file was downloaded as "our file.mj". However FireFox and Chrome acted very differently, in FireFox the file was downloaded as just "our", and Chrome as "our file.xml". In FireFox it appears that the issue is caused by having a space in the file name, this forum post by funkdaddu helped me on this, so by removing the space FireFox could now download the file as "ourfile.mj". Chrome however did not want to play ball. It was still insisting on...
