All seats have been taken. Please write a comment to be put on a waiting list, there are always a number of cancellations, so there’s still a chance.
Douglas and I have talked about him speaking at Geek Meet a few times when we’re ran into each other at different conferences in the world, and we’ve said that if he’s nearby Sweden, we just make it happen. Now is that time!
Being able to easily specify what to post with XMLHttpRequest is quite a powerful way of sending things to the server, using key/value pairs and FormData. However, many seem to have missed this gem, so I thought I’d outline it here.
This post was originally published for Mozilla Hacks.
One thing which has been very important when it comes to creating special end user experiences have been the ability to show something fullscreen, effectively hiding all the other content etc.
It’s been a while since I last shared some good reading, but hey, it’s 2012 now, so I thought I’d share my first batch this year!
In the fall of last year I was happy to be interviewed by Helen Emerson for The Developer Book Club.
I will soon start blogging more here again, now that time permits – for now, however, I’d like to share a round of good links I’ve collected recently.
First idea was to publish these posts on a regular schedule, but I’ve realized now it will be when I have enough good links (and time :-). Tons of links now, so, here goes – another issue of Robert’s read!
Forms on the web. They are literally everywhere, and there seem to really be all kind of flavors for them. From day one they have been a great mean for users to input data and information and interact with various services. And what comes with that is every implementation under the sun to offer validation for them, custom display and functionality if they aren’t native in that specific web browser, and much much more. Therefore, during the development phase of HTML5, one of the important things that have been looked into is making forms on the web evolve into what both end users and developers need to make things easier. Why would every web developer have to invent the wheel again or include tons of JavaScript code just to make something very basic like a datepicker work?
When the AJAX wave came in 2005 when Jesse James Garrett coined the term and then everyone wanted it, one of the major shortcomings was that dynamic updates of only portions of a web page lead to inconsistent history handling and back/forward navigation button problems in web browsers and poor end user experiences. Enter the HTML5 History API.
People are creating amazing things with HTML5 canvas, especially combined with other HTML5 features. I thought I’d touch on a handy method that some people don’t seem to know about: canvas clip.
Yesterday I had the pleasure of speaking at the London Ajax Mobile Event in, surprisingly, London.
HTML5 is here to save us all: it has the cool functions, eye-dazzling features and APIs to go around. I get to see a lot of great things developed with HTML5, but I’d like to issue a word of caution as well.
I wrote about it on Twitter last week (follow me on Twitter!), but naturally I should mention it here too, my dear readers. With new input from testing Internet Explorer 9 and from the Opera team, I have updated my HTML5 tests and compatibility tables and CSS3 tests and compatibility tables.
The other day at work we had a discussion about how code should look, or rather, what characters to use.
Geek Meet is now sold out! Please write a comment to be put on a waiting list.
Time for the first Geek Meet of 2011! And man, this will be a great night!
With HTML5 video and the current support in web browsers, we need to cater to different codecs, and fallbacks for web browsers with no native video support. This is where Video JS steps in.
To me, something about HTML5 that makes it quite interesting is all the new support for file interaction. I’ve written about the File API and reading file information before, and I thought I’d expand on that and add uploads and progress bars.
I just encountered the weirdest bug with the HTML5 autofocus attribute in Google Chrome and Safari.
With a blog it’s great getting comments, but as any blogger need to realize, there are other channels that people like to express their reactions in to – especially Twitter.
For a long long time we have tried to be able to push information from the server out to the end users without having to poll the server all the time.
I continually talk about HTML5 and how progressive enhancement is a simple approach to make any new behavior possible in web browsers that haven’t implemented it yet. I thought I’d show you a simple example how to do this with the new placeholder attribute for input elements.
One of the key things to improve performance of a web site, real as well as perceived, is including your JavaScript files at the end of the document (as I described in Improve Your Web Site Performance – Tips & Tricks To Get A Good YSlow Rating). However, there is a drawback to that.
It is soon summer (Yay!) and about time for a last Geek Meet before a summer break!
When writing JavaScripts for a web page, since the beginning of time, web developers have had the need to store extra data for HTML elements. I remember reading about custom data attributes in HTML5 some time ago, and recently Remy reminded me about them – they are here to save us!
A constant drag when developing web sites have been when the end user wants to upload files to it. Luckily, though, those problems are to come to an end due to the File API.
When performing advanced load-heavy operations in a web browser, both the web page it is run in as well as the web browser UI becomes unresponsive till it’s finished. However, there’s a way to address that with HTML5 Web Workers.
Ever had the need to communicate between windows or the current window and an inner iframe? Across domains as well? I bet you have, but now we have a nice option for doing that!
At MIX10 yesterday, Microsoft announced IE9 and spoke about its upcoming features. And, lo and behold, they released a Internet Explorer Platform Preview for anyone to download and play around with!
More and more services around us focus on where we physically are located at the moment, and how we can be assisted in the best fashion depending on that. Today I’d like to introduce the geolocation possibilities we developers have, and also play around a little with Google maps.
To follow up on the topic of cutting down the number of HTTP requests that I mentioned in my posts How to improve your web site performance – tips & tricks to get a good YSlow rating and How to reduce the number of HTTP requests, I wanted to put together a good list of tools and approaches to concatenate and minify CSS and JavaScript files in different developing environments.
I hope you are all having some nice time off; I just wanted to take the time to reflect on 2009 and what it was like for me.
I had the pleasure of spending last week in Lisbon, Portugal, for the Codebits conference.
Next stop on my little European tour is Codebits in Lisbon, Portugal!
I’m (almost) just back from Full Frontal 09, and man, did I have a good time! 🙂
About a week and a half ago, I had the pleasure of speaking at JSConf.eu!
Week before last, I had the pleasure of attending and speaking at two conferences. With even more conferences in the pipe, last week was pretty intense, work-wise, to cover up for that, but now I thought I’d take the time to talk about them, starting in this post with the Øredev 2009 conference.
I’m very happy to say that I will speak at at, and participate in, JSConf.eu in Berlin this upcoming weekend!
Soon time for me to go on the road, and I’ve gotten the honor to speak at the Full Frontal – JavaScript Conference, 20th November 2009.
It seems like everyone is talking about HTML5 now, but the discussion is spread out and seldom gives the background, explanation what HTML5 really is and if/when it’s usable.
In November, more exactly Wednesday November 4th, I will be speaking at the Øredev 2009 Developer Conference.
Last weekend, I had the pleasure of being invited by Mozilla to Prague to, amongst other things, discuss the future of Firefox.
Late last night I came home from the fantastic event that was Mozilla Camp Europe Prague, 3-4 October 2009, and I thought I’d tell you how my Prague visit was, what I thought of the event and my thinking about the sessions.
When a developer writes code, it is usually for the challenge, the obstacles to beat and the rush of solving a problem. But also, when your code becomes popular is quite a kick as well.
When I released Firefinder back in May, I had some ideas with what more I wanted to do with it. Now I can happily say that I have implemented those ideas!
Firefox 3.5 was released yesterday, and it has already reached 5 and a half million of downloads (at the time of writing). Therefore, I thought I’d answer some common questions, especially from a web developer perspective about the new version and which web developer extensions which will work with it.
I’ve had a few versions of my PictureSlides to create JavaScript slideshows, but now it has been completely rewritten and jQuery-optimized with some new control and features.
With the impending release of Firefox 3.5, I thought I’d cover the new things in JavaScript 1.8.1 – part of that is the very exciting support for native JSON, and you know what? They’re not the only ones supporting it!
Saving state or values have never been easy on the web, especially on the client-side, and using cookies have been far from ideal. Enter DOM/Web Storage!
I meet lots of developers working with different technologies and tools, and one thing that interests me is which, if any, JavaScript library they use.
Yesterday we had Geek Meet Charity in Stockholm, and in my opinion, it was a great success!
