"Testing for Navigation Timing API is a pretty easy was of verifying if the browser is Safari - Chrome, Firefox and IE 9 all support it - Opera, Android Browser, Safari don't" - Andy Davies

"There are spare rail terminals under T5 that were put in for a link from the West" - Andy Davies

"You obviously never tried flying into Schipol on a foggy day, it's chaos with four to six hour delays. Even though aircraft can land in foggy conditions, their separation distance has to be extended etc." - Andy Davies

"I'm missing how a larger initcwnd is relevant to the beacon collector - surely it's just getting requests and serving a 204 back - or is there more to it?" - Andy Davies

"Thx, can see how that would be smaller, it's a perfect case for a icon font - all monochrome images of various sizes" - Andy Davies

"Is there a link to the ~650KB image that was removed anywhere - one problem I see a lot is people not optimising images" - Andy Davies

"Yes, it should work on a 32bit version of XP, there's nothing that limits this to Win7 (I've never installed one on XP myself though)" - Andy Davies

"Unless its "exams are not an effective way of measuring some kids knowledge and skills" so they should do apprenticeships" I don't understand your point. And as professional apprenticeships e.g. with KPMG require A levels the statement doesn't make much sense to me eitherSchool seems to be the are where we want to concentrate solely on high stakes testing, written assignments become equally as important when people go to university and...What about experience? I certainly wouldn't want to be operated on by a doctor who's only ever passed exams and had no practical knowledge!" - Andy Davies

"It's easier to change the exam system than it is to fix education... What about all those people who exams aren't the right way of testing their knowledge and skills? The quality of education varies enormously and changing the exam system for 16 year olds isn't going to fix some of the problems caused by poor junior schools. "The emperor fiddles while Rome burns" springs to mind" - Andy Davies

"Fun an Anglo-French competition may be but perhaps the English sides need to look at why they don't do so well in the H Cup at the moment..." - Andy Davies

"4. Not sure - which is canonical, the URI or the hash? 5. They are a URI based on the specs as they currently exist though aren't they?" - Andy Davies

"1. It's not just custom libraries, people just don't upgrade the versions of common libraries that are in use e.g. back in February a two year old version of jQuery was the most widely used from Google's CDN (based on data in the HTTPArchive) 5. In what way are we treating different URIs as the same at the moment? 7. Caches are space limited particularly on phones and other devices, we will always need browsers to expire content from them." - Andy Davies

""The Heineken Cup is not an equitable share up of the rewards and the Celts benefit disproportionately." Of course they don't, the whole attraction of the Heineken Cup is that it included teams from across Europe, if the Celts and others aren't in it then it's no longer a European cup and doesn't have the same appeal or revenue opportunities." - Andy Davies

"It's an interesting idea but I can see a few issues with it... 1. Common versions of libraries etc. may be much less common than people might expect. A while back I analysed the versions of jQuery loaded form the Google CDN that the HTTPArchive project have come across crawling sites (http://www.slideshare.net/Andy..., the number of versions of jQuery in use is quite wide and this excluded all the custom builds. 2. Presume you would rely on the hash of the uncompressed version of the file? 3. The hash has to be calculated and inserted into the HTML element, every time the source file changes this hash would have to be inserted again - yes this can be automated into build processes etc. 4. What's the behaviour if someone inserts an incorrect hash for their own resource? 5. It breaks URI conventions by treating two different URIs as the same 6. Why just <link> and <script>, why not the other external resources too? How would you manage a font referenced in a stylesheet though? 7. I..." - Andy Davies

"No it's here http://eoin-clarke.blogspot.co..." - Andy Davies

"Profit of £30,000/year per employee - figures are out there somewhere but can't remember where (Tim Harford perhaps)" - Andy Davies

"There are plenty of regular fliers from outside the city.  Even decent transport links will make a estuary airport at least an hour further away than Heathrow. At that point it becomes easier to fly long haul from places like Birmingham via Paris or Dubai that trek out to the Thames marshes" - Andy Davies

"The Thames estuary is the wrong place - it has flocks of birds, ships full of explosives and the flight path clashes with Dutch and Belgian approaches The other things that's wrong with the Thames estuary is it's on the wrong side of London for most people." - Andy Davies

"I specifically wanted to move the attribute setting out of the javascript for a couple of reasons 1. Many people pull in jQuery to do it which although easy seems overkill from a performance / battery life perspective 2. The attributes and conditions in which they are altered gets buried in the JS - I can imagine a nice JS library to help with this so might start work on it (if I get time) 3. As someone who's been writing code for a long time I like the simplicity and clarity of a declarative approach Idea was driven by what I see in the real world, doing performance audits on real sites and see how they were managing it or not! If you've not ready it Tab and Fantasai's proposal is well worth a read." - Andy Davies

"Yeh, would be really good if disqus supported limited MD" - Andy Davies

"Thanks for the comment and sorry about your lack of sleep! I tried hard to just to stick to presentational use-cases but yes the idea would be open to abusing separation of concerns, but then we can do that now with JS and there are times when it's the right thing to do. Tab and Fantasai's Cascading Attribute Sheets specifically promote the setting of non-presentational attributes i.e. for ARIA I'd have to re-read the CSS vars spec as I don't know if it allows the use of vars in media-queries e.g. you could have a slim set of MQs in the HTML that set a viewport alias e.g. S/M/L that can be used in other MQs in the CSS (that's just come of the top of my head so no idea on the practicalities or problems of this approach)" - Andy Davies

"Is the server reverting to the internet template rather than the custom one, or is the custom template using it's ICW=10 setting?" - Andy Davies

"I've had a look at it and the other ideas floating around on custom properties but none of them seem to quite fit these cases." - Andy Davies

"I've got friends in Holland who watch the BBC via Satellite who found they are unable to buy a TV Licence when they tried. Enjoy our TV but remember the BBC can be a bit full of themselves at times!" - Andy Davies

"Nice piece of work... There is some stuff on fallbacks for unsupported image types in the CSS3 Images spec - http://dev.w3.org/csswg/css3-i..." - Andy Davies

"Interesting article... But if you're going to post a waterfall can you use one that's from a realistic scenario rather than a local HTTP server? How do things like requirejs handle merging of JS requests?" - Andy Davies

"Before you get too excited that faster connection speeds might bail us out I'd recommend reading "More Bandwidth Doesn't Matter (Much)" by Mike Belshe - http://www.belshe.com/2010/05/... We need lower latency as well as more bandwidth..." - Andy Davies

"You forgot the stats comparing mobile browsers over cellular and non-cellular connections" - Andy Davies

"I flew back from the US on Saturday and landed around 1pm. There were virtually no queues in terminal 3 and I cleared immigration in about 5 minutes." - Andy Davies
