(oh and forget about other better browsers) yay for killing progress<br /> [*] This will kill new browsers (in the long term), because they not only have to implement the current standards, but the behavior of every older rendering engine to have web compatibility.<br /> [*] IE8 won't support Acid2 on release, because the Acid2 site doesn't choose a rendering engine :---o<br /> [*] embedded content, what happens if a widget is designed for the latest IE/Firefox/Opera, and then the host webpage is turned onto IE3 computability?, this just means developers will have to support rendering engines way past their time <img src='http://blog.thedt.net//content/plugins/emoticons//msn_sad.gif' alt=':('/><br /> [/list]<br /> <br /> <br /> Links to blog posts which explain this issue way better than me <img src='http://blog.thedt.net//content/plugins/emoticons//msn_tongue.gif' alt=':P'/><br /> <a href="http://robert.accettura.com/archives/2008/01/22/meta-stupidity/">http://robert.accettura.com/archives/2008/01/22/meta-stupidity/</a><br /> <a href="http://lists.w3.org/Archives/Public/public-html/2007Apr/0279.html">http://lists.w3.org/Archives/Public/public-html/2007Apr/0279.html</a><br /> <a href="http://ventnorsblog.blogspot.com/2008/01/meta-better.html">http://ventnorsblog.blogspot.com/2008/01/meta-better.html</a><br /> <a href="http://weblogs.mozillazine.org/doron/archives/2008/01/whats_up_doctype.html">http://weblogs.mozillazine.org/doron/archives/2008/01/whats_up_doctype.html</a><br /> <br /> <br /> edit:<br /> <br /> pft list bbcode broken<br /> <br /> <span style="color:red">*me will fix later...</span> Wed, 23 Jan 2008 06:53:53 America/Los_Angeles dt http://blog.thedt.net/post/7/IE's_new_meta_tag http://blog.thedt.net/post/6/new_dtblog_feature New dt blog feature <img src='http://blog.thedt.net//content/plugins/emoticons//msn_grin.gif' alt=':d'/> editing comments without being a registered member <img src='http://blog.thedt.net//content/plugins/emoticons//msn_happy.gif' alt=':)'/><br /> <br /> =p though... its not like anyone comments here anyway.... o; Tue, 15 Jan 2008 22:04:29 America/Los_Angeles dt http://blog.thedt.net/post/6/new_dtblog_feature http://blog.thedt.net/post/5/New_year So its another year another year of nothingness and uni : <<br /> <br /> dt is currently working on big things though....<br /> <br /> <span style="font-weight: bold;">Happy New Year crazy internet people</span><br /> <br /> <random><br /> I've decided if i ever have a daughter her name will be <a href="http://www.thinkbabynames.com/meaning/0/Arianwen">Arianwen</a> because its an awesome name <img src='http://blog.thedt.net//content/plugins/emoticons//msn_happy.gif' alt=':)'/><br /> </random><br /> <br /> Mon, 31 Dec 2007 01:51:49 America/Los_Angeles dt http://blog.thedt.net/post/5/New_year http://blog.thedt.net/post/4/Messenger_Plus_Script_update_checking_tutorial <span style="font-weight: bold;">This is a tutorial on Script version checking and updating</span><br /> tutorial by -dt- (Matt Labrum)<br /> <br /> <br /> So you've made a script, and you want to make sure your users have the most current version of your script.<br /> Well you've come to the right place. This tutorial is about exactly that!<br /> <br /> Now I'm going to assume a few things<br /> 1) you're not a complete noob<br /> 2) you're not segosa<br /> 3) you have a script (If you don't just create a new one)<br /> 4) the script must have a ScriptInfo.xml file<br /> 5) somewhere online where you can upload files<br /> <br /> Now that thats out of the way, we can get to the fun part <img

what the hell are all those tags" well <img src='http://blog.thedt.net//content/plugins/emoticons//msn_sad.gif' alt=':('/> I'll explain each one<br /> <br /> ScriptInfoUrl - the location of the updated scriptInfo.xml (our checker will download this file and compare it to the current one)<br /> PlscLocation - Plsc to download if our update checker detects that we need updating<br /> ReleaseNotes - optional, the changelog to display to the user<br /> DateReleased - optional, the date the new version was released<br /> <br /> <br /> Now i bet you're wondering how the update checker will work. Well, inside your script's OnEvent_Initialize you'll trigger UpdateChecker.Check(), which will then download the update xml (gets this value from Update/ScriptInfoUrl).<br /> Once the updateXML is downloaded it will trigger UpdateChecker.parseUpdate() which then compares the local ScriptInfo.xml <version> tag with the downloaded ScriptInfo.xml <version> tag.<br /> If it's a newer version then the script will display a dialog to the user asking them if they want to update, if they say yes then your script will download the plsc file and run it.<br /> <br /> Diagram of how all this fits together<br /> <a href="http://random.thedt.net/tutorial/scriptUpdating/tuturialDiagram.jpg"><img width="650" height="210" src="http://random.thedt.net/tutorial/scriptUpdating/tuturialDiagram.jpg"/><br /> (click for a bigger image)<br /> </a><br /> Now to make the javascript for the above process<br /> <br /> Create a new
