Page Speed Score: 93/100

Google made a post the other day about “Me and site performance, sitting in a tree…” so I thought before we get to the “…k, i, s, s, i, n, g!” I should give her a run for her money, check she is good enough for me.

First thing the post suggest is to check out Site Performance in Webmaster tools, so off I went. When this first appeared in the Labs section of webmaster tools it was updating pretty regularly and was quite useful and as the graph shows helped me tweak a few things and improve the load time of the server. But it hasn’t been updated in a while now so isn’t very relevant or useful to me.

Next thing it suggests is to install Page Speed for Firebug and test my site. So thats what I did and I got Page Speed Score: 93/100! which is pretty impressive. So I thought next, 7% to go, what can I do to get to 100/100. Nothing it seems… All the suggestions the tool gave me were unsolvable and prevent anyone from getting top marks.

The first suggestion is to Leverage browser caching,
the file it advises me need to do this too is “http://www.google-analytics.com/ga.js” which I cant do anything about.

The next suggestion is to Defer loading of JavaScript, “66.4% of the JavaScript loaded by this page had not been invoked by the time the onload handler completed” is smugly informs me.
- http://gavtaylor.co.uk 24 functions uncalled of 25 total functions
- http://www.google-analytics.com/ga.js 154 functions uncalled of 243 total functions.

On closer examination the functions it reports on my site are actually from Firebug, which must be open for the test to run? catch 22 there!
And the analytic code again is from Google and I cant do anything about that.

The final suggestion is to Use efficient CSS selectors,
http://gavtaylor.co.uk/core/styles/styles.css has 12 very inefficient rules, 27 inefficient rules, and 0 potentially inefficient uses of :hover out of 101 total rules.

This I can do something about and when I get a moment I will be re-coding my CSS file. But this wont improve my results more than 1 or 2 points.

So this unreachable target of 100/100 appears to be impossible. I could remove the Google code from my site which would resolve the Google plug-in issue but I cant run the test without having Firebug open so there will always be 24 out of 25 uncalled functions reported keeping me away from that 100/100 score.

So… will I be sitting in that tree, doing things I should not be?… No, not until they fix the issues with their testing tools anyway…

Update 4/4/11:

On Thursday (31st March), Google released an online version of their page speed tool, This new test works in the same way to the Firebug plugin but uses a version of webkit installed on a server. I have written a quick follow up post with links and my initial thoughts here.

01100001011011100110010001110010011011110110100101100100

For a while now, I’ve been wanting to learn how to build and develop mobile applications on Android, I made a start using Appcelerators Titanium, but not long after during a press conference, a certain fruit seller announce his phone was banning apps developed using 3rd party tools. While this didn’t affect me directly, as I have no interest in the iPhone or developing for it, this news meant that the future of Titanium has been thrown into doubt and I don’t want to learn and start developing with a product that may not be around in a years time.

With this in mind, this last week or so I have been dipping my toes into the wonderful world of native Android development.I have gone for the setup advised in the SDK documentation, Eclipse with the ADT plugin. Quickly passing over the Hello World app, as a developer its a task I must complete before doing anything else, I started on my first application. I decided that for my first attempt I would stick to something I know and rebuild a web based tool I help develop for a well known Manchester server hosting company.

Its been a long time since I last did anything in Java so was a little rusty, but after a few lunchtimes and couple of late nights I have managed to cobble together something that resembles and could just about pass for an Android Application.

So what is it you ask, this wonderful app you have been building up (wont shut up about if you follow me on twitter)? Well I can now tell you, its a speedtest. Not for how fast your mobile connects to the internet, I’ll leave that to the guys at speedtest.net, but to test the speed your website can deliver files to your visitors, now I cant provide you with a link to download and install it as its not really finished and as its not an officially sanctioned app, but I can show a couple of screen-shots from the current alpha version.

This is probably as far as this application goes, unless the boss asks me to continue with it, as although its quite basic and there isn’t all that much to it, it has served its purpose and helped me to figure out how an application should work, its activity life-cycle and how to correctly put one together.

The next step is to think of that award winning, must have, how did we live without it idea that will make me millionaire… any suggestions?

Missing TortoiseSVN Shell Icon overlays

This has been bugging me for weeks and today I finally found and resolved the problem so thought I should share in case anyone else has this problem too.

I couldn’t remember when I first noticed they were missing but when ever I checked a working folder on my laptop the tortoise svn icon overlays were missing. When I edited a file the red cross would appear as expected, but the green tick to say a file was up to date or the question mark for non-versioned files were missing, meaning I didn’t know if a file was up to date with the repo head or an ignored/non-versioned file.

This morning I came across a post on stack overflow that suggested modifying the registry to over-right the usual Microsoft default setting cock-up. In Windows, for memory reasons Im guessing, they have limited the number of allowed Shell Icon overlays to 11. Now at first this seems like a logical way to stop memory abuse in Explorer. But for some stupid reason (most likely so their overlays come first), they are actioned in alphabetical order, so any overlays in position 12+ are ignored. With M being in the middle of the alphabet this results in the majority of these slots being allocated by Microsoft Products. In this case Tortoise SVN (obviously starting with a T) was being pushed out of the allowed slots.

I found this out by doing a search in the registry for ‘ShellIconOverlayIdentifiers’ (NOTE: only open regedit if your comfortable using it, we don’t need to change anything just taking a peek so you should be ok). This reviled that most of the Shell Icon slots were being taken up by something called Microsoft Groove. Not having a clue what this is I turned to a popular search engine to find out.

Microsoft Groove is the name for their multi-user document collaboration tool, which makes sense that it would need some icon overlays as it is essentially the same thing as Tortoise SVN. I don’t do any online document collaboration so re-searched for how to remove it. The Microsoft knowledge base article advised to remove the feature from Office via the add/remove programs control panel but when I looked I couldn’t find anything that mentioned Groove but after a further search or two I found that it has now been renamed to Microsoft SharePoint Workspace, which was listed in my version of Office. I disabled the feature and restarted my laptop and I now have my overlay icons back.

Verify your domain via DNS

Google have announce another way to verify you own a domain in their webmaster tools, via a DNS TXT record.
This solves a problem I have had many times in that it verifies the whole domain.

Until now, you had to verify you owned every sub-domain on a domain before you could use webmaster tools for it, while for most sites this is fine, you verify the www. version, sometimes there are a couple more that need to be done.
for example on my site, I use the non-www domain, also there is a dev. and a api. that also need their own verification meta tag/html file. If I want to use webmaster tools on another sub-domain I have to verify again… this becomes a tiresome process.

Enter the new DNS verification. You now add a TXT record to your dns and it automatically covers any sub-domains you add.
That’s it… done! There is of course the usual dns propagation you have to worry about so it may not be a quick as adding a meta tag, but it defiantly saves time in the long run.

You can find out more by visiting the Google Web master tools or popping over to the Webmaster Central blog.

First IE9 Platform Preview Available for Developers

Microsoft’s IE development team have announced their first developer preview for the latest version of Internet Explorer.

IE9 is rumoured to include several <html5> and CSS3 elements, making it a real contender in the new range of “modern browsers”.

You can read more about the release on the IE Blog, or jump straight over to the resources and “test drive” the new release.

I will update this post with my thoughts on the preview, once I’ve had a play with it.
