Gmail vs. Exchange

My university is using Exchange at the moment and now is deciding whether to continue using it or change to Gmail (for Business/corporate).

To fellow IIUM staff, as far as domain name is concerned we will still be using our extension to the name. I support the migration to Gmail even though I was the strong supporter for Exchange few years earlier. Why?

  1. Today is the era of Cloud computing & between Gmail & Outlook, it’s no brainer, Gmail gets two thumbs up.
  2. The best about Exchange & Outlook is its ability to invite meeting appointment. Now, Gmail can also do that. Having said that how many really use the feature?
  3. Oh I better ask the most important question. How many  really use our IIUM email? Many will give the excuse that IIUM email is not reliable. So it’s another reason to switch to Gmail. Known for its reliability.
  4. How much space you got for Exchange? 1 GB? Oh…it is 500MB…. ha ha ha. And many staff complained that they have to delete & clear many emails in the mailbox. With Gmail you’ll get 25GB.
  5. Security & confidentiality. Hmmm.good question. But how many is using Yahoo or Hotmail or Gmail to send their exam questions to the exam administrator? So don’t talk about security & confidentiality lah. If you want security, use encrypted message. Oh you don’t know what is encryption? So don’t talk about security or confidentiality.

I say, let’s change! I know that UM is using Gmail. And you guys are talking about ownership & security with those top in World University Ranking (compared to us) has been using it for some time.

I am no longer holding any IT post in the university, and this is my personal view.

How to jailbreak iPhone. The beginning.

This tutorial is for those who do not kno what jailbreak (or JB) is but want to try to JB their iPhone.

JB is a way to allow your iPhone to use applications not sold in iTunes Store. There are many apps that are pretty cool but not available in iTunes. Among I like the most are BiteSMS & MyWi.

JB your iPhone also allow you to access the root folder of your iOS. To those Linux geek, they can do magic when they can access the root.

So how to JB?

First, you must know what version of iOS you have on your iPhone. To know that go to Setting > General > About. Just read the ‘Version’ info. That’s your iOS version. Then google for famous jailbreak tools like RedSn0w & Greenpois0n. If your iOS is old enough, you can simply JB your phone using I will not going to repeat the steps one by one as it is usually specific based on iOS version.

One thing to know, there are 2 types of JB. Tethered & untethered. Tethered means you must be connected to your PC, run the specific tool before you can use all the JB apps. Every time the phone reboot, you need to tether back to get the JB.

Untether is the way to go. But sometimes you don’t have the option as the untether may be taking long time to be available.

So before you hit the update button in your iTunes, decide whether you want to use the JB apps or not. Once updated, difficult to downgrade unless you save the SHBLOBS of your phone in Cydia. And later use certain tool (like TinyUmbrella) to downgrade the iOS.

Another thing you need to master before you JB your phone is to enter DFU mode. The steps is pretty easy.

  1. Switch off your phone.
  2. Press the Power button & hold it.
  3. Wait until you see the Apple logo & press Home button while still pressing the Power button.
  4. Once the Apple icon disappear, release the Power button & keep pressing the Home button.
  5. You are now in DFU mode.

So what will happened once you had successfully JB your phone? First and foremost, usually you’ll get Cydia icon in your iPhone. From Cydia you can search & install extraordinary apps not available in iTunes. Some are free & some are paid version. What paid?? Yes. JB does not mean CRACK or illegal apps okay! Even though JB make it possible for your iPhone to be installed with cracked apps…especially when you have added certains repositories.

Now, what is repositories? It is web address to site that store all those apps. Some paid, but many are illegal sites…well…they allow you to install cracked apps don’t they. ;)

Good luck!

Javascript code was missing!

YES! Finally I managed to find the solution of this Photoshop problem that I have been having for months. Suddenly (I believe after I upgraded my MacOSX) few of the default Automate plugins e.g. Fit Image & Photomerge disappeared even though they are all there when I checked the folder. The error code was “Javascript code was missing”.

I searched forums after forums…..and I even reformatted the entire Mac thinking it as a solution.

The solution is pretty simple, rename the default Application (installation) folder to something else! VIOLA! All problems gone & photoshop is now able to locate the file.

BTW I am using CS5 with iMac (MacOSX 10.6.5).
