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!
Not many people know it, but you can use “real” getters and setters in JavaScript if you want to.
It’s been some time since the last event, but man, are we making up for it this time! Time for Geek Meet Charity June 4th 2009!
Lately I’ve been investigating newer versions of JavaScript, and what web browser support they have. And, as usual when I create something I find useful, I want to share it with the world.
Just playing around a little, I’ve created a new command for Ubiquity.
One of the most common mistakes I see with web sites is demanding of the end user to know technology.
Let’s talk about what we should know and learn, shall we?
About a couple of weeks ago, I was approached by a Mozilla employee suggesting I talk at one of their events.
I have just released a new version of my Firefox extension Inline Code Finder and made a personal download record!
During the fall, I put a fair amount into writing an article for the Opera Web Standards Curriculum, and now it has finally seen the light: Handling events with JavaScript!
Admit that you have always wanted to know how to develop a Firefox extension but never had the time to learn. Here I will walk you through and at the end of the article we will have created a fully functional Firefox extension!
Most of you probably know about photo sharing at Flickr, and share and/or view your friends’ and families’ photos there. In my humble opinion, though, their set/gallery view could offer a better experience, and therefore I’ve set out to improve it with Flickr Gallery Plus!
Ever felt that you have had the need to enhance your web browser, or the functionality of some web site you frequently visit? Here I will explain how to do that.
The end of 2008 is near, and I felt it was time to summarize the passed year.
When I first coded and released Obtrusive JavaScript Checker, I had some more ideas with it, as well as some great feedback I have received and wanted to see to. The result is Inline Code Finder, which looks for inline styling as well as what the Obtrusive JavaScript Checker offered, and it comes in two versions!
Today I thought I’d introduce you to timers in JavaScript and how to use scope to make your life easier.
When I review web sites, and also in my own projects with a number of different team members, I almost constantly stumble across something web developers should really refrain from: inline styling and inline JavaScript code.
It was time for me to stop being a whiny lazy developer, and instead properly learn to develop Firefox extensions. So. the result is version 0.8 of Obtrusive JavaScript Checker, as a very much improved Firefox extension.
Something which have troubled web developers for a long long time is the proprietary event handling implementation in Internet Explorer. In IE 8, this really has to go.
With the latest release of Obtrusive JavaScript Checker and its cool information and report features, I got the request to make it as a command for Ubiquity as well. So, here you go!
When I launched Obtrusive JavaScript Checker, I immediately felt it had more potential, and I definitely had more features to add to make it even more compelling. Therefore, here comes a new release with javascript: link support, detailed inline event information and a summary report.
In my work, part of it is analyzing both other people’s code as well as my own. Now I have created Obtrusive JavaScript Checker to help me out with that!
I guess some of you hard-core developers and keyboard shortcut lovers out there immediately took Mozilla’s Ubiquity extension for Firefox to your hearts when the first version was released in August. Now I have created a command to perform a search in my own web site with the help of Ubiquity, and naturally I want to share it with you.
When talking about JavaScript and inheritance, something that often go amiss from the discussion is the alternative of using proper namespacing instead.
After my recent posts about JavaScript, there were some people asking for more information about inheritance – intrigued by the concept myself, and also inspired by Andrea Giammarchi’s comment , I though I’d come up with some scary shit.
One of most tricky behaviors by JavaScript interpreters is semicolon insertion.
After reading JavaScript inheritance – how and why and Explaining JavaScript scope and closures, I thought we’d combine the knowledge gained to talk about private, privileged, public and static members (properties and methods) for objects in JavaScript.
I thought I’d try to explain something which many people struggle with: JavaScript scope and closures.
Some time ago, I had lunch with a former colleague I last saw in 2000, when we were working together in a project. We got to talking, and eventually he asked me an interesting question.
Currently I’m working a fair bit with JavaScript and teaching different ways to use it, and what I want to talk to you about is if and how you use inheritance in JavaScript.
