ibm aix

Maybe this still has a place in today’s tech world, but I think IBM should just give up and move over to working with true *NIX clipped from en.wikipedia.org IBM AIX AIX (Advanced Interactive eXecutive) is the name given to a series of proprietary operating systems sold by IBM for several of its computer system platforms, based on UNIX System V with 4.3BSD-compatible command and programming interface extensions. Latest stable release 6.1 / November, 2007 Source model Closed source License Proprietary

Useful Unix Commands

To backup everything in the current directory, exclude anything ending with jpg: tar cvf mybackup.tar –exclude “*.jpg” . To exclude more than one type, just add another –exclude statement: tar cvf mybackup.tar –exclude “*.jpg” –exclude “*.gif” . Search current directory and sub directories for mp3 files: find . -name \*mp3 Need to Learn: how to get the total size of the files returned by the above search command AIX Those were on RHEL, not aix – they will work for a lamp instance.  With AIX we have to consult the man tar page. This should work: find . \! -name “*.mp3″ > inputfilelist tar -cvf mybackup.tar -L inputfilelist This should also work (in the opposite direction): find . -name “*.mp3″ > excludefilelist tar -cvf mybackup.tar -X excludefilelist . In either case, you can use this to see if there are any mp3 files in the archive: tar -tvf mybackup.tar | grep mp3

Multiple Clipboards

I wish Windows had native capability for multiple clipboards, or clipboard cycling. There are a lot of third party clipboard apps, but I find them bulky and buggy for what they do. But it would be totally easy to hit ctrl+c an extra time to store something, or perhaps ctrl+v twice would past the penultimate item.

Reopen closed tabs – Chrome and Firefox

I love the Ctrl+Shift+T function to reopen your accidentally closed tabs in Firefox and Google Chrome. That’s the other thing that Chrome did right – used intuitive shortcut keys based on good industry standards (ie: Mozilla).

Information Wants to be Free

I think it’s a fantastic philosophy. I agree – it does want to be free.

Google Chrome and Plugins

I really wish Google Chrome allowed plugins. Of course Google is probably not too happy about the idea as it might compromise stability of the browser. Plus it would mean they have less control over things – like greasemonkey scripts removing their clickTracking and sponsored ads. But it’s a shame because the browser is so fast (mainly with Javascript), and it’s also pretty good with standards and features (like moving towards css 3 selectors), but mainly it just loads quickly and it doesn’t take up too many memory problems. (I realize that firefox would also load faster if I disabled some of my extensions, but they really just help speed up my workflow.) Oh yeah, and Chrome’s break-away tab thing is pretty cool. I’d love to be able to move tabs between windows in firefox, or break them out more easily. Oh, and finally it’s pretty cool how the browser has some built-in crash-protection / recovery which will keep the OS out of it. @google – Would love to see a (non-hacked) mac version.

Drupal vs Joomla vs WordPress

I’m trying to get a sense of how these three stack up against each other. It’s hard to know how many installations (worldwide) there are of each, since they are free and available for download, but this is a project of which I’m interested in adding some stats in the future. software # installations user accounts developer accounts annual downloads wordpress 2,600,000 ? ? ? drupal ? 500,000 2000 1,500,000 joomla ? 255,000 ? ? I do have to say that WordPress seems to be the most polished software of the three I’ve seen so far. WordPress won’t create valid html code for my table, so I guess this document isn’t really XHTML 1.o compliant like my theme’s footer says. Sigh.

Xhtml Friends Network

XFN™ (XHTML Friends Network) is a simple way to represent human relationships using hyperlinks. In recent years, blogs and blogrolls have become the fastest growing area of the Web. XFN enables web authors to indicate their relationship(s) to the people in their blogrolls simply by adding a ‘rel‘ attribute to their <a href> tags, e.g.: <a href=”http://jeff.example.org” rel=”friend met”>… To find out how to write and use XFN, or to write a program to generate or spider it, visit http://gmpg.org/xfn/   This is also kind of similar to the vCard and hCard microformats.  Check these out at http://microformats.org/

IE Hack – Hide Text on your Submit Buttons

The Issue: I was not able to hide the text from the button, letting the underlying image to show it’s text. Normally my preferred image replacement technique is to have text in the background image and then use a negative text-indent at a high number like this: background-image: url(‘my-picture-with-text.jpg’); text-indent: -9999px; This works fine with submit buttons on most browsers, except IE. The fix: Add 2 extra lines to your css file: color: transparent; text-transform: capitalize; For some reason the text indent dosn’t work by itself in IE, so after adding these 2 lines it works. It is a hack within a hack though, the color:transparent property should work by itself, but it doesn’t. For some odd reason setting the text-transform to anything (in this case I chose capitalize because I don’t use it very often) makes it magicly work. Anyhow if anyone finds this useful please leave a comment below. Source
