Colorize
Why color? This will increase productivity and reduce eye strain. A quick look and you can get a quick overview of the content being displayed.

Enable colorized file listing (ls) – add “alias ls=’ls -G’” to ~/.bash_profile
Enable colorized vim
1. Run “sudo vi /usr/share/vim/vimrc”
2. Add the following lines to the top:
  syntax on filetype plugin on set ruler

Hash Checking
Add the following lines to your “~/.bash_profiles”:
alias md5='md5 -r' alias md5sum='md5 -r' alias sha1sum='openssl sha1'

[SOLVED] Migrating Google Reader from GMail to Personal Domain Google Apps with Starred Setting

Mr. IT Guy — Mon, 24 Oct 2011 21:55:58 +0000

I was using a mix of personal domain email and GMail for a long time. I now migrate to Google Apps and find that Email and Calendar can be transferred easily. The harder one to figure out is how to export the starred items in my Google Reader. Here’s how to migrate starred items.

Login to your gmail (old account)
Goto Settings -> Import/Export
Export OPML file and save it
Goto Settings -> Folder/Tags
Check the box for “Your Starred Items”
Above that, click on “Change Sharing” and choose “Public”
Click “View public page” (preferrably on a new tab) and click on the “Atom Feed” icon
Copy the URL to the clipboard
Logout of your old account and login to your NEW account (works with account switching too)
Goto Settings -> Import/Export
Import the OPML file you downloaded earlier
Go back to Google Reader main page
Click on “Add a Subscriptions”
Paste the URL from the public page atom feed
You will now have a new feed for all your old starred items. Star each of them now.
After you star each of them, you may remove the atom feed and also delete the other feeds from your old account.

[SOLVED] iPhone 3GS Stuck in DFU (Black/White Screen)

Mr. IT Guy — Thu, 30 Jun 2011 23:41:47 +0000

My 3GS was on 4.0 JB and I tried to update to a clean 4.3.3 using sn0wbreeze. Alas, it went into DFU during the restore and never came back. I have inclination that it may have something to do with boot animation. I tried to use iReb, fixrecovery, redsn0w, limera1n, etc but nothing works. Regular iTunes restore always returns with error code varying from error 21,22, 23, 1600, etc. But, I noticed one thing, when I tried to use redsn0w, it seems that the phone reboots, shows a blank white screen then go back to black screen and stuck there.

I was about to give up when I stumbled upon iRecovery. First try, it doesn’t work. It complains about not finding the phone. So, I tried to use redsn0w to restart the phone and see that glimmer of white screen and see if iRecovery would be able to hook itself to the boot session during that moment. So, I fired up redsn0w and repeatedly run the command “iRecover -s” in the command prompt. I basically pressed up and entery over and over during the process.

The first try didn’t work and I have to redo it again. The second was the charm and it JB properly.

[SOLVED] run32dll.exe Application not found

Mr. IT Guy — Mon, 23 May 2011 21:34:57 +0000

After virus removal using your favorite AV or Anti-Malware, you may run into a problem of missing run32dll.exe. This happened to me after running BitDefender Live CD on a computer infected with MS Tool malware. Other symptoms includes instances where shortcuts to applications not running.

Use notepad.exe (if you’re unable to launch, use another computer or any file that write a text file) and write the following:
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\exefile\shell\open\command] @="\"%1\" %*"
Save the file as fix.reg and run it.
Reboot your computer

[SOLVED] Word 2007 Cursor Constantly Blinking Rapidly Between Busy and Arrow

Mr. IT Guy — Thu, 19 May 2011 01:26:57 +0000

The first symptom I notice is that whenever I open MS Word 2007 is that the cursor would constantly blink rapidly between the busy and arrow. The second symptom I notice is that after a while, I’m getting “There is insufficient memory or disk space” error.

After scouring websites advising about changing the normal.dot file and still having the problem, I found another site that recommends deleting printer from the “Devices and Printers”. Before I tried that, I change the default printer to “PDFCreator” and it solves the problem. I didn’t have the time to troubleshoot it, but it maybe SNMP or network related, but documents actually prints just fine. So I’ll leave it at this for now.

[SOLVED] Logitech SetPoint Stuck Modifier on Keystroke Assignment

Mr. IT Guy — Wed, 16 Mar 2011 17:23:31 +0000

I recently had a problem with some sticky modifier after pressing a button on my mouse with keystroke assignment (even predefined ones like Back and Forward). After some troubleshooting and backtracking, I found that the issue is having Synergy running. After I disabled Synergy, everything works normally. For those who don’t know what’s Synergy, “Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s).” (quoted from http://synergy2.sourceforge.net/).

[SOLVED] App2SD Missing Apps after restore – nandroid-mobile.sh to /sd-ext shows Read-Only file system

Mr. IT Guy — Tue, 08 Feb 2011 05:41:46 +0000

On Friday, I finally pulled the trigger and moved to CM7 Nightly. That night, I also found wildmonks kernel for CM7 Nightly, so I run nandroid backup before installing the kernel. Everything seems good and peachy. I also really liked the new animation for screen on and off.

Today I received notification of a new nightly available. Since ROM Manager works best with ClockworkMod recovery, I flashed it and do a full backup. When I moved to the new nightly built #34, I found that Tasker crashes all the time. So, I restored to my backup from this morning. Alas, the restore procedure always got stuck at the “Dalvik-Cache”.

I tried to do wipe cache and dalvik-cache and restart. The CM7 loaded, but all my App2SD installed apps are missing. After probing here and there, I finally decided to switch back to Amon Ra recovery, adb into the system and perform the nandroid restore manually.

Everytime nandroid try to restore the sd-ext partition, it always shows that the tar unable to create directory because the partition is mounted as read only. After forcing an rw mount and the problem persists, I finally was about to give up. Then I was thinking if it’s possibly due to the ext4 filesystem. Finally I reformat the partition using ext2, upgraded to ext3 and perform the manual restore (using tar) and it works.

Finally I got my system back to the Friday midnight backup. I flashed my new kernel and got everything back working.

So, if you find yourself unable to restore ext partition when using App2SD and ext4, try to revert back to ext3.

[HOWTO] Unstuck between 3.1.3 and iOS4

Mr. IT Guy — Mon, 28 Jun 2010 22:57:34 +0000

I was trying to upgrade to custom iOS4 right after the release of Pwnagetool 4.01, but got stuck with error 1600 and 1604. Apple stopped signing 3.1.3 so, I can’t get back to 3.1.3 to get the phone unlocked. Basically the phone is stuck in restore mode. Here’s how i manage to get out of the restore mode and use 3.1.3.

Download Blackra1n
Run blackra1n. If you have ASL.DLL error, make sure you copy blackra1n.exe to
C:\Program Files (x86)\Common Files\Apple\Apple Application Support
When the device reboot, pay attention to the screen. Once it get out of the restore mode, quickly unplug the data cable. If not, repeat again.

Once done, you may want to upgrade to iOS4 the right way

[HOWTO] From iPhone 3GS 3.1.3 Spirit Jailbreak to iOS4 Sn0wbreeze

Mr. IT Guy — Mon, 28 Jun 2010 22:39:53 +0000

WARNING: NO warranty is provided with this guide. Follow at your own risk.

A lot of info that iPhone 3GS 3.1.3 with Modem Firmware 05.12.01 can only be jailbroken using spirit jailbreak and no way to upgrade to iOS4. Here’s a full unlock of iOS4 when you’re stuck at 3.1.3 spirit jailbreak.

Restore to default with 3.1.3 and JB using spirit
(if can’t activate, then you can try without restore)
Use Cydia to install the following packages: afc2add, openSSH, MobileTerminal
Download Spirit2Pwn and extract
Get sn0wbreeze 1.5.2
Get 3.1.3 ipsw and 4.0 ipsw
Create a 3.1.3 Customer firmware using sn0wbreeze. Ignore the warning (if any) and just create the firmware. We’re not going to restore using this firmware anyway.
Firmware should be put on Desktop. Go to desktop and rename it to something that identify it as 3.1.3 Sn0wbreeze firmware. Also, change the extension to zip.
Extract the zip file
Connect your iPhone to your WiFi. Use SFTP and login to your iPhone. If you have no SFTP client, you can use FileZilla. Default username/password combo is: “root”/”alpine” (without the quotes)
Copy all the files you find in “Firmware/all_flash/all_flash.n88ap.production” (from the extracted custom firmware) to iPhone’s “/tmp”
Copy all the files you extracted from spirit2pwn_r2.zip to iPhone’s “/tmp”.
NOTE: Some reports error, so you may want to make another copy of “pwn_old_boot_r2.sh” on the /tmp named “pwn_old_boot_r1.sh”
Once done, SSH into the phone using PuTTy or use MobileTerminal on the phone
Use the same credentials as the SFTP credentials. Then run the following commands:
cd /tmp chmod 755 pwn_old_boot_r2.sh chmod 755 pwn_old_boot_r1.sh ./pwn_old_boot_r2.sh
Wait for the process to say “SUCCESS”
type “reboot” and let the phone reboot
Download sn0wbreeze 1.6.1
Create custom firmware for iOS4
Use the Shift+Restore (on Windows) or Alt+Restore (on Mac) and point to the custom iOS4 firmware.
NOTE: If you’re not using iTunes 9.2 at this point, an error (13) will be raised
After complete, use Cydia and install the same packages again (openSSH, afc2add, MobileTerminal) and add another repository: http://repo666.ultrasn0w.com
Find Ultrasn0w and your phone is now jailbroken and unlocked on iOS4
