Re: Loading webfonts with high performance on responsive websites - http://bdadam.com/blog...
"I'm not sure I agree that "it only takes *a* site to take one for the team" as there's no guarantee that once a font is downloaded how long it will stay in the cache - we're building sites that consume more and more cache, and using many different fonts from many different foundries. Not sure I follow the bigger question of when browsers are going to become more responsible - originally browsers didn't block waiting for the font and display the page anyway until we (devs and designers) complained we didn't like the experience it gave our visitors, so instead they started waiting for font. Ilya's got an interesting proposal to allow us to have greater level of control, but we'll still have a challenge when we choose to use a font - https://github.com/igrigorik/c..." - Andy Davies

"Even with a cache lifetime of a year there's no guarantee that the font file will stay in cache, as depending on how frequently it's uses a browser is likely to eject it so it can cache other content" - Andy Davies

Re: Optimizing the Critical Rendering Path - http://www.sitepoint.com/optimiz...
"Key thing to remember with webfonts is they block rendering in Safari, Chrome, Opera and Firefox - the last three wait 3 seconds before timing out and falling back to a default font, Safari waits longer. But… The browser doesn't know which fonts it needs until the render tree is being built i.e. until the CSS styles are matched against the DOM, and only then does it request them - it's one of the reasons fonts can be such a painful user experience on slow networks. We then get into the tradeoff of base64 encoding fonts which of course results in larger CSS, so longer download and later construction of the render tree, which is why people go down the route of storing them in localStorage. Ilya Grigorik put together a great idea for controlling font-blocking behaviour in more detail - https://github.com/igrigorik/c..." - Andy Davies

Re: One of the most destructive taxes of the past 40 years could soon be axed - http://www.telegraph.co.uk/finance...
"UK manufacturing industry was dead in the 70s, Thatcher's mistake was not to encourage other manufacturing to replace it (we can argue things like encourage Nissan did to an extent)" - Andy Davies

"Why should retired people be given special dispensation - they're amongst the biggest gainers in the property boom we've have, pension costs are the largest component of the social security budget (you don't see politicians mention that), and the cost of supporting ever increasing life expectancy is huge." - Andy Davies

Re: Why is my CDN 'slow' for mobile clients? - http://www.igvita.com/2014...
"A while ago someone in the UK who does network design for operators told me that different operators have different approaches e.g. Vodafone had multiple egress points, and O2 had one. Given the UKs small size and concentration of peering in London not sure one approach really has benefit over the other from backhaul latency perspective." - Andy Davies

Re: On Brighton beach: austerity, alienation and the battle for democracy - http://www.opendemocracy.net/ourking...
"1. So there's nothing wrong with being forced to join a union when you start work somewhere - what every happened to free will? 3. Secondary picketing was a widely used form of intimidation against those who may not have been directly involved in the dispute. As for the current government not being democratically elected, they may not have had a majority, and indeed the Tories may have had less MPs than Labour but Labour could not form a government (or chose not to - if so a clever choice on their part) I prefer to think of the last election as the electorate rejecting both parties (Labour have an inbuilt advantage in the way the boundaries are drawn) If perhaps the unions of the 70's had grasped the modernisation of British industry instead of being so opposed to change then Thatcher may not have won in 1979." - Andy Davies

Re: On Brighton beach: austerity, alienation and the battle for democracy - http://www.opendemocracy.net/ourking...
"Our industrial relations in the '70's were abysmal, yes companies might have been part of the problem but the unions were too - much of the union legislation Thatcher's government introduced is a reaction to that. Would you like to tell me what's wrong with: 1. Removing the closed shop where people were forced to be a union member of they were out 2. Secret ballots, for selecting union officials, and whether to strike 3. Banning secondary picketing Unions dictating to an elected government (as in the 70's) is unacceptable - an often it wasn't the union members doing it but the ego's of their leaders. Whether we like the current government or not, it doesn't remove the fact that they were 'democratically elected' and we'll have the chance to remove them in a few years, we never had that chance with the unions in the 70's The state of the UK economy in the 70's was down to the failings of businesses, government and unions - everyone was stuck in a post colonial past where Britain 'was..." - Andy Davies

Re: On Brighton beach: austerity, alienation and the battle for democracy - http://www.opendemocracy.net/ourking...
"I was with you until you complained about the Unions being muzzled, they were out of control in the '70s and in many ways the controls on them were a reaction to that There's some parts of the union legislation that they resisted but no-one in the right minds can object to e.g. secret ballot, the right for others to go to work without being intimidated by those on strike. Strikers today still have a habit of call those who continue to work 'scabs', it's encouraged by union leaders and it's essentially a form of bullying." - Andy Davies

"I'd love to be able to see SpeedIndex generated in the browser - challenge of course is getting it accepted as a metric to measure. Other challenge I see with SpeedIndex is it's not as easy to grasp as timings in seconds, or sizes in kB, so we have some work to do to enable people to understand it." - Andy Davies

"If you've already pulled down xcode you can use the Network Link Conditioner - Slowy is just a slightly easier to use interface onto the same feature in the OSX network stack. It's also worth mentioning that the mobile agents in WebPageTest (WPT) use the MobiTest agent but you can control the network speeds and latency in WPT. Hoping to get a MobiTest (via WPT) location up and running in the UK in the New Year." - Andy Davies

Re: The pros and cons of using R packages for teaching - http://timotheepoisot.fr/2013...
"I put language in quotes as I meant more than just the basic syntax of R (which is pretty simple really), I guess what I mean is the whole ecosystem, there are definitely packages and methods where the API could have been better designed. I've got a few R books but thanks for the list will check it out." - Andy Davies
