What is currently in demand is PHP5 that means OOP, any framework eg CakePHP/Zend or CodeIgniter and Jquery (Javascript) or good enough or on its own the serious Drupal experience.
If you’ve got these you are gold dust, if not you are … dust …
any comments?
Years ago Microsoft announced that Windows would be Data Driven rather than Application Driven. In your Start Menu you could see a list of recent documents worked on images, spreadsheets,databases. You just had to click on one of them to re-open it. Strangely hardly anyone used it, and Microsoft, as is their wont, forgot about it as well. It was however extremely useful, here is how to reenable it in Windows 7.
Right click the Start/Win button, select Properties
Click the Start Menu tab (it should be select as default)
Click the Customize button
Scroll down and check the Recent Items check box
Click Ok
Click Apply
Click Ok
You should now have a “Recent” option in the start menu.

There are two ways:-
$price=~tr/0-9.//cd; # delete anything but 0-9 and a real dot
$row_array[6]=~s/[^0-9.]//g; # clean up price, remove pound/dollar sign etc
the <C-R>a automatically inserts whatever variable you had previously stored in register a
I’d put some new files into a folder before remembering to mothball all the old files:-
Here is a zsh solution:-
>mv *.*(^m-1) ./old
You know the frustration of being able to log into a website because your browser has
remembered the password but you have forgotten it and so cannot login from another pc.
Well FireFox will show them to you
options->security->Saved Passwords then click Show Passwords
You may want to consider the security implications as well, to disable this feature while
retaining the ability of the browser to remember passwords
go to
options->security-set master password
I personally never let a browser remember say my PayPal password
The sed does the filtering, you should be able to see how to adapt this to your own requirements
So I want to duplicate init.php while changing the value of a flag inside it for each copy
cat init.php | sed s/flag=2/flag=3/ > dir3/init.php
cat init.php | sed s/flag=2/flag=4/ > dir4/init.php
If you see the first comment Bawdo suggests rightly that this is a UUOC
sed “s/flag=2/flag=4/” init.php > dir4/init.php
I’ve always underused sed unfortunately
which then can written (zsh)
for i in {3,4}; sed s/flag=2/flag=$i/ init.php > dir$i/init.php
sed stands for stream editor and therefore cannot do an in place edit this is where perl thrives
perl -p -i -e ‘s/\surname\b/form_surname/g’ *.php
or safer
perl -p -i.bak -e ‘s/\b23\b/34/g’ fred.php (creates a backup of each file eg fred.bak)
Today I had to update a 12 year old Higgledy-piggledy Microsoft Access Database application to work with the year 2010 instead of 2009 amongst other things . The original designer had needlessly hard-coded the current year’s and previous year’s date anyway I had some notes from when I did it 12 months ago which described what values need changing, but could I find where those values were defined? My notes were not specific enough. The REAL PROBLEM was that last year I must have altered these values without too much of a sweat and so not taken much trouble to note down exactly.
Fortunately I remembered the wonderful stackoverflow.com website. I posed my question and got several useful pointers in a few minutes and these helped me find the solution which was to set the option search whole project.
This is actually a generic problem in life when we realize that we’ve been doing something automatically and been unconscious of how we did it.
