I’m a little embarrassed to say that I only looked this up for the first time today. Although, I’ve been programming in JavaScript for so long that I must have known this years ago, but “forgotten” as I haven’t done much JavaScript programming in the last few years. Hey, at least I retained that niggling feeling like I had to look that up!
Important: JavaScript does not have block scope.
Basically:
var x = 1;
{ var x = 2; }
print( x ); // outputs 2
I’ve been working my way through the Code Igniter documentation and have the basic framework properly configured in Pcphpjs now.
I worked through the Getting Started with Doctrine guide this evening, putting my content in the Pcphpjs project. There were a few hurdles to jump over, but in the end I got the sample application working in PHP with SQLite.
Recently after my hosting provider hard-booted one of my machines the MySQL service started to complain “Failed To Read Auto-Increment Value From Storage Engine” when an insert was issued to any table with an auto increment field. I found the solution here, and it basically requires you to reset the auto increment key on the table, like this:
ALTER TABLE `table_name` AUTO_INCREMENT =1
I had to do that on all of my tables that had auto increment keys to resolve the issue.
I found the configuration setting in the documentation that will force phpMyAdmin to automatically track tables during and after creation. It is:
$cfg['Servers'][$i]['tracking_version_auto_create'] boolean
And the default value is ‘false’. I updated:
/var/www/www.progclub.org/pcma/config.inc.php
With the line:
// JE: 2011-09-07: force tracking $cfg['Servers'][$i]['tracking_version_auto_create'] = true;
Linus has moved Linux to GitHub.
Found this article today, How does “this” keyword work within a JavaScript object literal?. It describes various ways of calling a function in javascript, and explains what the ‘this’ context will be in each case.
A pretty nifty feature of MediaWiki tables is the class=”wikitable sortable” specification. Adding the ‘sortable’ class automatically makes the table sortable. Handy!
I’ve updated our Members table as well as a few other tables on the wiki to use the ‘sortable’ feature.
I was doing some research about free software licenses as a part of developing ProgClub’s terms and conditions, and found this list of free software licenses from the FSF, and the same list of FSF approved software licenses on Wikipedia. I noticed the cool table sorting facility they have on the Wikipedia page, and wonder if that’s built in to MediaWiki..? It would be cool if it only required a class specification to have it work like that.
I’m working through Zed Shaw’s Learn Python The Hard Way, and I’m up to exercise 5. Doing the extra credit 3 involved searching online for Python format strings, and I found that there is the old way, which is presumably what Shaw wanted me to find, and also the new way in which a new scheme for string formatting is provided.
