http://bivald.com/lessons-learned/ Lessons learned is where I publish everything from articles, texts and links to project previews, creative ideas and code snippets. Simply my lessons learned. While the portfolio always will be a way for me to publish my finished work, lessons learned is the place where I simply hope to share my experience. en Copyright 2008 Mon, 29 Dec 2008 13:46:06 +0100 http://www.sixapart.com/movabletype/ http://www.rssboard.org/rss-specification www.highscalability.com/ is a great resource for web service (or application) scaling. It collects articles on application scaling that varies from:

• Theoretical scaling
• Hand-on
  
• Statistics and information

The last one takes a look at which scaling solution different large sites uses. A must read.

Javascript gave the following errors:
"MT is not defined"
"JT is not defined"

And so on. After a little searching I came up with this post which states that the problem is due to a corrupt mt.js (in mt-static). If your file is below 10 KB, you have a problem. Simply download the installation files from movabletype.org (matching your version, of course) and replace mt.js. It should now be ~100 KB.

Worked like a charm

For starters, register on Iphone Dev Center and download and install the SDK. Read the objective c primer and at least fast-read through iPhone development guide. Then the fun starts - making your own application.

The absolute best resource for this (IMO) is icodeblog.com (Iphone Programming Tutorial) There you will find step-by-step tutorials on both how to get you started as well as how to use the different components

   Be able to reach files on the computer from anywhere
   Be able to view the screen from anywhere

First one was easy: SCP. Second was more though, while OS X Leopard has the built in screen sharing (vnc) I didn't feel like opening up the screen sharing to the world. Therefore I started looking for resources how to tunnel VNC over SSH and at the same time restrict screen sharing to local IP (without using external firewall to block)

I found what I needed on http://fotinakis.com/blog/blog/2008/secure-mac-screen-sharing/

Basically what I did was:

   1. Changed port on the sshd and then starting the remote login (ssh from system preferences) - I followed http://www.macosxhints.com/article.php?story=20050707140439980 I used 22222
   2. Deny all incomming connections to port 5900 and 88 from everyone but me using ipfw

Then when I want to connect to the shared screen, I open up my SSH tunnel:

ssh username@ip_address_or_hostname -L 5901:localhost:5900

And connects (Finder -> Go -> Connect to server) to vnc://localhost:5901

Note though, you must tunnel it from a port that is not 5900 otherwise you will get a "You can not connect to your own computer"

I will give http://jamieorc.wordpress.com/2008/03/23/setting-up-a-headless-mac-mini-without-a-monitor/ a shot, basically:

1. connect a keyboard to the Mini
2. start the Mini in FireWire Disk Mode
3. connect the MacBook Pro to the Mini with FireWire cable
4. restart the MBP using the Mini as the boot disk
5. setup the Mini with network access and remote management (Sharing)
6. reboot the MBP with its own disk
7. disconnect the Mini and reboot

From the above mentioned source.

(PS: On leopard server? Try http://www.bos89.nl/1218)

In that case, you need to be aware that you need to add a / for it to work, like this:

From http://drupal.org/node/9418:
herefore :
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
becomes
RewriteRule ^/(.*)$ /index.php?q=$1 [L,QSA]
in my case

Second seminar, which I held today, was more in-depth on their upcoming assignments but also gave them a deeper understanding of Javascript and Ajax, "Web 2.0".

Third seminar which will be held on Monday focuses on the actual creation of HTML/CSS/Javascript. How do you make a website?

Fourth seminar will be held on the 8th of October and is when then will be showcasing their experiences. I will update with more information later on..
