Tips: Download iPhone SDK with wget

zaher14 — Fri, 16 Jan 2009 15:57:00 +0000

Since its final release, I’ve been trying to download iPhone’s SDK from Apple’s website. The whopping 1.6 GB download seems a pretty daunting task in my unstable line, and some of apple’s web sites features made it pretty impossible in no time.

My download failed three times after 50-70% completion, each time either I have manually paused the download for some reason or my connection was having some problem. And apples server did not give me any resume feature in any of the download managers. Downloading 1.6 GB with Firefox’s own download manger seemed an option, but what if Firefox crashes?

At last, I thought of giving good ol’ wget a try and it didn’t fail me. If you are in a similar situation like me, try this.

Downlaod ‘Export Cookie’ addon for firefox from here
Log into iPhone Developer Site using your apple developer account, if you don’t have one, just register, its free.
Export your cookie using the addon to a file named ‘cookies.txt’
Run this from the command line
wget --limit-rate=5k --tries=inf -server-response --continue --load-cookies cookies.txt http://adcdownload.apple.com/iphone/iphone_sdk_for_iphone_os_2.2__9m2621__final/iphone_sdk_for_iphone_os_2.2_9m2621_final.dmg

Now you can pause and resume the download at your will. I have used –limit-rate=5k so that I can also browse without much overhead.

Javascript: Getting Current Window Dimension

zaher14 — Wed, 14 Jan 2009 13:35:00 +0000

Javascript function to get current window height and width. Works with most of the browsers.

// function to get the current width of the windowfunction getWidth(){ var x = 0; if (self.innerHeight){     x = self.innerWidth; }else if (document.documentElement && document.documentElement.clientHeight){     x = document.documentElement.clientWidth; }else if (document.body){     x = document.body.clientWidth; } return x;}

// function to get the current height of the windowfunction getHeight(){ var y = 0; if (self.innerHeight){     y = self.innerHeight; }else if (document.documentElement && document.documentElement.clientHeight){     y = document.documentElement.clientHeight; }else if (document.body){     y = document.body.clientHeight; } return y;}

System Admin: EDGE/GPRS via Bluetooth in Linux Simplified

zaher14 — Mon, 06 Oct 2008 12:28:00 +0000

This is an update to one of my earlier posts. I was trying to find a more portable way with wvdial and came up with this.

Start with the same command,
$hcitool scan
We get some info

Scanning ...
 00:1D:FD:36:9E:DB 3110c Emerald

Here “00:1D:FD:36:9E:DB” is the blue-tooth address of my phone.

Time to put this address into good use. We’re going to bind this blue-tooth address with a specific device identifier.
$sudo rfcomm bind 0 00:1D:FD:36:9E:DB 1
Let me put some light into this command, the second argument in this command (in this case 0) is the device identifier, the third is the blue-tooth address (distinct for each device) and the fourth is the channel number which is typically 1.

After executing this command this mobile phone is directly accessible through /dev/rfcomm0

As said earlier, we are going to use wvdial this time. But we need to do another trick.
$sudo ln -s /dev/rfcomm0 /dev/ttyS4
Now we just run
$sudo wvdialconf
You should see some output in the terminal
Editing `/etc/wvdial.conf'.

Set phone number to *99***1# and Username and Password to anything you like.

$sudo wvdial

MacOS X: iSync AppleScript

zaher14 — Fri, 12 Sep 2008 10:57:00 +0000

I wanted to run iSync Priodically everyday so that my mobile and MacBook get synced regularly, this is what I found after some googling:

tell application “System Events” to set isync_running to (name of processes) contains “iSync”


tell application "iSync"
  activate
  if isync_running is not true then
      tell application "System Events" to set visible of process "iSync" to false
  end if
  synchronize

  repeat until syncing is false
      delay 1
  end repeat

  if sync status is 2 then
      if isync_running is false then
          quit
      end if
  else
      activate
  end if
end tell

save the file with a .scpt extension and add the script in iCal to run every day.

Tips: Run Linux apps in Mac OSX Seamlessly

zaher14 — Sat, 19 Jul 2008 04:04:00 +0000

I have been using Vmware Fusion to run Ubuntu 8.04 and Windows XP for a while. I really like the idea of Unity while using Windows in Vmware as it seamlessly integrates Windows and Mac OSX apps.

I was a little sad to find out there is no such feature for Linux. Guess what, I was wrong. While I was fiddling with different ssh options, I came across a feature called X11 forwarding. With the use of X11 forwarding, its easy to accomplish the same effect. All you need is just add ‘-X’ option while you ssh and make sure you have a working X11 environment installed in your Leopard.

$ssh -X zaher@172.16.90.128

Its as simple as that. After login, just run any graphical program you want like a native application. You can also disable X11 in your VM since it has the added benefit of using low memory than usual as no X11 us running in your Virtual Machine.

Here is a screenshot of Firefox, Gimp and OpenOffice.Org running from my Ubuntu Hardy Heron in Leopard.

Mission: Recover Disk Space: Part 2

zaher14 — Fri, 18 Jul 2008 04:36:00 +0000

Hmm, the mission is going pretty well, next step download Monolingual. This cool Open Source tool checks your MacOSX system for redundancies like localized documentations, not platform specific apps and gives you a choice to remove them selectively.

I was able to about 2.8 Gigs from my last run, as I only kept English and Bengali localizations and Intel specific installations.

I love the icon of this app very much,

Mission: Recover Disk Space: Part 1

zaher14 — Fri, 18 Jul 2008 04:16:00 +0000

This was getting more and more annoying day by day. My hard drive was getting full day by day as i kept installing new apps but somehow the rate of hard drive usage wasn’t matching the applications installed. Something was wrong and something need to be done.

I installed OmniDiskSweeper and gave it run. I noted a folder called /cores which was taking a whooping 5.4Gigs. Suspicious, I looked it up and came to know that this is the folder where my Leopard keeps its memory dump files after any system crash for debugging purposes. Since it didn’t concern me, I just safely deleted these annoying core.xxxxx files to reclaim my precious 5.4 Gigs.

So if you are also running out of space, don’t forget to check that folder.

Debug PHP scripts in Netbeans IDE

zaher14 — Thu, 03 Jul 2008 16:57:00 +0000

Are you having problems in finding pesky quirks in your PHP scripts and swelling your fingers by writing print_r in almost every lines? This tip is just for you …

Download and install “Early Access for PHP” bundle of Netbeans from http://download.netbeans.org/netbeans/6.1/final/ .

Download and install an appropriate PHP-Mysql distro. I’m using MAMP in my Mac OS. Another good platform independent option is XAMPP.

Download the appropriate version of xdebug from http://www.xdebug.org/ matching your php version (use phpinfo() in your web server to grab that). In my case there was no Mac OS binary, so I had to download the source. If you are downloading binary package then you can skip to step 7.

Unpack the source and open a terminal in that folder.

Now run [Note: make sure phpize and php-config is in your path]:

$phpize


$./configure --enable-xdebug

$make

A file called xdebug.so (in Linux and Mac OS) or xdebug.dll (Widows) will get created. If you have downloaded binary package, your package will contain this file.

Now copy this file into the extension folder of your server. In my case it was like this

$cp modules/xdebug.so /Applications/MAMP/bin/php5/lib/php/extensions

Now open your php.ini file and add entries for this new extension

zend_extension = "/Applications/MAMP/bin/php5/lib/php/extensions/xdebug.so"

xdebug.remote_enable=1

Now fire-up Netbeans and create/open your php project. Now insert a breakpoint by clicking anywhere in the left margin, now try to debug the file by selecting debug from context menu. You should see your web browser being fired and probably a blank web page. Now press F7 to step into your code and see it execute step by step. Try adding some watches. As the whole page finishes executing, you get to see the result in your web browser.

Happy Debugging!!!

Update 5 July 2008:
Just found out this link for configuring xdebug with netbeans in Ubunutu 8.04.
