• OnEdit / OnFocus Hook or Similar in Bespin Embedded?

  - by Don Albrecht

  I'm trying to implement a hook when text is edited in a bespin embedded instance. Ideally, I'd simply like to know when the instance has gained or lost focus to capture the user action.

• Most hazardous performance bottleneck misconceptions

  - by David Murdoch

  The guys who wrote Bespin (cloud-based canvas-based code editor [and more]) recently spoke about how they re-factored and optimize a portion of the Bespin code because of a misconception that JavaScript was slow. It turned out that when all was said and done, their optimization produced no significant improvements. I'm sure many of us go out of our way to write "optimized" code based on misconceptions similar to that of the Bespin team. What are some common performance bottleneck misconceptions developers commonly subscribe to?

• How to set up Atana Studio 3 Themes in Pydev

  - by willy1234x1

  I've installed the Aptana Studio 3 preview and noticed it has support for themes (such as a bespin style or Ruby envy) and I'd love to use the Bespin one in Pydev but so far I've had no luck getting it to work, anyone have a clue as to how to get it to work? Video showing the themes in action.

• Cloud9 IDE : première offre Cloud de Développement-as-a-Service open-source, issue d'un projet de la fondation Mozilla

  Cloud9 IDE : première offre Cloud de Développement-as-a-Service Open-source, issue d'un projet de la fondation Mozilla Ajax.org vient de lancer une nouvelle plate-forme de développement entièrement Cloud écrite en JavaScript et HTML5 : Cloud9 IDE. La nouvelle plate-forme, issue de la fusion avec le projet Skywriter (ex. Bespin) de la fondation Mozilla est destinée à faciliter et accélérer le développement, le test et le déploiement des applications Web et mobiles. En plus des standards Web, l'IDE-as-a-Ser...

• Which mobile device is appropriate as a utility tool for a web master?

  - by Kayle

  Basically, I'm looking for a device to use on the road and I would prefer to not have to sit down for the majority of the tasks (which rules out netbooks, in my mind). I'm also hoping to spend less than $500. This is what I'd like to "capably" be able to do on the device: Browse the web in non-mobile format, flash is a plus Email, chat, etc Have access to a decent text editor and ftp OR a browser that supports BESPIN/ACE Some sort of SSH support I'm looking at rooted Android phones and iPhone/iPads... though the phone aspect is only icing (it would be cool to consolidate the two devices and have net access through cell networks, but I'm not married to the idea). Are there cheap linux tablets that are ready for prime-time yet? I suppose that would be ideal. All suggestions welcome!

• What web based programming environments exist, on which to learn?

  - by jjclarkson

  I loved appjet (the programming environment) before it was taken over by Google. What other web based complete programming environments are out there? Which one do you think is best for starting to do real world coding the fastest? I really think coding from your browser will make programming more accessible to the public. Are there any out there that use a vim style, (e.g. jsvi) in combination with free server side hosting? The last time I looked at Bespin it was a little green. Are there others?

• Calculating usage of localStorage space

  - by WmasterJ

  I am creating an app using the Bespin editor and HTML5's localStorage. It stores all files locally and helps with grammar, uses JSLint and some other parsers for CSS and HTML to aid the user. I want to calculate how much of the localStorage limit has been used and how much there actually is. Is this possible today? I was thinking for not to simply calculate the bits that are stored. But then again I'm not sure what more is there that I can't measure myself.

• What are the advantages / disadvantages of a Cloud-based / Web-based IDE?

  - by Gabe

  I'm writing this as DevConnections in Las Vegas is happening. Visual Studio 2010 has been released and I now have this 3GB beast installed to my machine. (I'll admit, it has some nice features.) However, while the install was monopolizing my computer's resources I began to wish that my IDE worked more like Google Documents (instantly available, available anywhere, easy to share, easy to collaborate, naturally versioned). A few Google (and StackOverflow) searches led me to : Coderun Bespin I'm well aware that these IDE's are missing a lot of what exists in VS 2010. However, that isn't my question. Instead, I'm wondering what benefits a web-based IDE might have? Assuming a company invests the time to create the missing features, what is the downside?

• Will html5 and Javascript replace native applications?

  - by nimo

  I recently attended a conference on future of the web and web development and it was a lot of focus on HTML5 and how it will impact the way we look at the web and how we will use it. The majority of the speakers meant that it will replace native application on your desktop as well as in your mobile phone. I agree that you will be able to make a lot of great stuff with the new technology take bespin for example and the <video> and <canvas> tag will be amazing, but will it completely remove the need for native applications? Is there something you cannot do with Javascript and HTML5?

• Structuring input of data for localStorage

  - by WmasterJ

  It is nice when there isn't a DB to maintain and users to authenticate. My professor has asked me to convert a recent research project of his that uses Bespin and calculates errors made by users in a code editor as part of his research. The goal is to convert from MySQL to using HTML5 localStorage completely. Doesn't seem so hard to do, even though digging in his code might take some time. Question: I need to store files and state (last placement of cursor and active file). I have already done so by implementing the recommendations in another stackoverflow thread. But would like your input considering how to structure the content to use. My current solution Hashmap like solution with javascript objects: files = {}; // later, saving files[fileName] = data; And then storing in localStorage using some recommendations localStorage.setObject(files): Currently I'm also considering using some type of numeric id. So that names can be changed without any hassle renaming the key in the hashmap. What is your opinion on the way it is solved and would you do it any differently?

• Suitable data structures for saving files in localStorage (HTML5) ?
