First Alpha of Public Sector Linux Deployment System 84

New submitter mathiasfriman writes: SverigeLinux (SwedenLinux in Swedish) is a project financed by the Swedish Internet Fund that is developing a Linux deployment system for the public sector. It is based on DebianLAN and has just released its first public early alpha version. This 7 minute video shows how you can deploy up to 100 workstations with minimal Linux knowledge in under an hour, complete with DHCP, DNS and user data in LDAP, logins using Kerberos and centralized storage. The project has a home on GitHub and is looking for testers and developers. Don't worry, no Björgen Kjörgen; it's all in English.

Comment Re:My Kingdom for a Datagrid Element! (Score 1) 541

When's the last time you laid out a site without a table element on every page?

Thursday. I was off sick yesterday.

"Oh, I want this box to highlight red when this happens!" a user might say.

Custom Events are your friend, and a sound basis for designing any complicated user-interface or series of interactions: http://developer.yahoo.com/yui/examples/event/custom-event.html So your problem above boils down to:

YAHOO.util.Event.on(thisBox, thisHappened, updateBox)

  • thisBox being a DOM reference to your table cell
  • thisHappened being the custom event you've defined as "this happens"
  • updateBox being the function or method that probably just adds a class name to the table cell, letting the CSS apply the necessary style changes

Another good writeup of custom events is: http://nefariousdesigns.co.uk/archive/2007/07/ajaxevent-using-yui-custom-events-with-ajax/

Having some sort of online presence is a great way to control (or at least influence) the image about you online. There's a heap of stuff on google about personal brand management. This one looked like it had a lot of relevant points regarding why you should consider this to be important: http://www.bruceclay.com/blog/archives/2008/04/building_personal_brand.html

Tim Bray on the Birth of XML, 10 Years Later 260

lazyguyuk writes "Tim Bray posts a lengthy blog on the birth of XML, formalized as 1.0 in Feb 1998. 'XML is ten years old today. It feels like yesterday, or a lifetime. I wrote this that year (1998). It's really long. The title was originally Good Luck and Internet Plumbing but the filename was "XML-People" and I decided I liked that better. I never got around to publishing it, so why not now?'"

Then there's Digg; Digg's pages are such a load on the visitor's CPU that I have to click "script not responding, continue?" three times on a page with 800 or so comments with Firefox and a dual-core 2 GHz CPU just to get the page to completely render.

Sounds like Digg is attaching events to every show/hide link instead of using event delegation and using only one event listener. Browsers can't really handle hundreds of attached event listeners, it is a known performance issue.

Now using event delegation instead of attaching hundreds of events should definitely be in a set of web development best practices.

Tech Magazine Loses June Issue, No Backup 245

Gareth writes "Business 2.0, a magazine published by Time, has been warning their readers against the hazards of not taking backups of computer files. So much so that in an article published by them in 2003, they 'likened backups to flossing — everyone knows it's important, but few devote enough thought or energy to it.' Last week, Business 2.0 got caught forgetting to floss as the magazine's editorial system crashed, wiping out all the work that had been done for its June issue. The backup server failed to back up."

Is Vista a Trap? 559

logube writes "BBC has up an article about the trap of installing Vista in your existing desktop. Written by Tim Weber, a self-confessed 'sucker for technology,' this article is a good introduction to the pain and extra money required to get going with the newest version of Windows. See how you can spend an extra 130 british pounds, and still have no working webcam! Says Weber, 'It took me one day to get online. The detail is tedious and highly technical: reinstalling drivers and router firmware didn't work, but after many trial and error tweaks to Vista's TCP/IP settings, I had internet access. Once online, Creative's website told me that my sound card was a write-off. No Vista support would be forthcoming.'"
