How to mute the camera shutter sound on Samsung Galaxy S2

The camera on Samsung Galaxy S2 is amazing, its 8.1MP camera takes HD pictures and videos. I found myself taking more and more pictures with it. However, Due to the privacy concerns, the camera shutter sound can’t be muted and it is really loud. It was bearable with single shot but made my time-lapse video shooting experience bad.

So I decided to mute the shutter sound by myself. After looked around, I was able to mute it completely and here is how I did it.

1. It requires the superuser permission, another word, you will need to root your Samsung Galaxy SII.

2. Use a file manager that can access system folders, I use the Root Explorer.

3. In the Root Explorer, goto the folder /system/media/audio/ui/

4. Within the /system/media/audio/ui/ folder, mount the folder as R/W so we could rename the sound files.

5. Once the system files are editable, look for the file named Shutter_01.ogg and rename it to something else. Just don’t delete it in case you may want to restore the camera shutter sound later.

6. Put the system folder back to R/O then exit Root Explorer.

7. You’re done! Go to camera and enjoy!

How to Fix Blank MMC extended view in Windows

Problem

I ran into a strange problem recently. When I open extended view of Services management console (Services.msc). It shows a blank page, however, the Standard view is functioning well at the same time. I tried to scan and fix the Windows files but the scan doesn’t report anything wrong.

Meanwhile, I am also having problem with IE. When I open a site in IE, all the links to JavaScript scripts are not working while the rest of links are fine.

Something wrong with JavaScript…

Solution

Re-register the JavaScript DLL to fix the problem.

Open a command prompt window, or press <Win>+<R>. Type the following command:

regsvr32.exe jscript.dll

 

Welcome to the real IT world, Obama staff

 

According to the Washington Post, the incoming U.S. presidential administration are upset by the outdated Office running on Windows, no Facebook and no IMs.

 

Well, welcome to the real world. That is exactly how the IT in 95% of corporations and  organizations works.

Here is list of most of common IT policies

  • No Facebook, what so ever. Facebook is simply blocked within the corporation network. Sorry and now get back to work.
  • IM clients, most likely ports are blocked. Unless it is for work.
  • Macintosh is not supported at all because those internal web apps doesn’t run well.
  • Blackberry, now get this, President. You could have blackberry and get emails on your corp. Blackberry. But there’s no way to install 3rd-party apps and they are blocked by IT Policy!
  • Office 2007, Vista? Not right now, because IT department has to test them before rolling out.

Basically that is exactly how people work everyday. Now stop being a baby and go back to work!

 

Fix: Windows 7 Beta gadgets not working issue

After a fresh installed Windows 7 beta on my PC. I am quite happy with the overall performance and features presented by this beta.

However, it seemed Windows gadgets didn’t work. Right click on the desktop and select gadgets but nothing happened. I tried to download some gadgets but it said “unspecified error” when I tried to install gadgets.

First of all, I thought it was a bug so I reported it. However, I found the cause and fixed it.

It was the UAC – User Account Control, causing gadgets stop working. After installed Windows 7 beta, I naturally set the level  of UAC to “Never notify”. Apparently it broke the gadgets. After restored the UAC back to default level or level 1. I am able to install and show gadgets on my desktop now.

Wired but worked, You will have to use default level at least level 1 for UAC to get the gadgets worked.

Read Digital Magazines for Free (iPhone is not Needed)

Apple Iphone owners get to view free digital magazines of 70 or so popular magazines without costs, courtesy of Zinio and Texterity, including Popular Mechanics, PC Magazine, and U.S. News & World Report.

However, non-iPhone/iPod touch browsers can also score free access using the User Agent Switcher extension for Firefox or a simple Safari tweak.

All that needs to be done is change the User Agent in your browser to the one of the iPhone which will trick the website into thinking that you are accessing it with an iPhone. This in turn will give you access to those magazines, among them PC Magazine, Technology Review, Macworld, Lonely Planet and, um, Playboy and Penthouse.

The content is provided in full screen in your browser and you can flip through the pages with a click. It’s probably not the most comfortable way but it’s free and easy enough. Pages are actually shown as images which means they can be saved to the local hard drive.

In Safari, set your browser to the iPhone user agent in the Develop menu, which you can enable at Preferences->Advanced->”Show Develop menu in menu bar.”

Opera users have built-in user agent switching for iPhones

Firefox users can install the User Agent Switcher add-on and configure it with the following User Agent:

Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420.1 (KHTML, like Gecko) Version/3.0 Mobile/4A102 Safari/419 (United States)

 

 

Then switch to that User Agent and visit the Zinio or Texterity.

 

Mac OS X is NOT safer than Vista.

As you surely know by now, the CanSecWest conference was the stage for a contest, PWN to OWN. Three laptops were set up; laptops running Windows Vista, Ubuntu Linux, and Mac OS X. The goal was to hack the computer and read the contents of a file located on each of the machines, using a 0day code execution vulnerability.

During the first day, you can only attack the machine over the network, without physical access. On the second day, user interaction comes into play (visiting a website, opening an email). On the third and final day, third-party applications are added to the mix. Each machine had the same cash prize on its head.

As you all know, the Mac was hacked first, on day two. The user only had to visit a website, and the Mac was hacked. Vista got hacked on the third day using a security hole in Adobe’s Flash, and the Ubuntu machine did not get hacked at all.

when the hacking contest was on its second day. The second day consisted of stock configurations along with browsers and some mail applications. That’s when the MacBook Air laptop was hacked in in about 2 minutes utilizing a Safari vulnerability that Apple has now been notified of.

Technically it wasn’t really Microsoft’s fault that the machine was hacked since Adobe is the one who creates Flash. The MacBook Air vulnerability, on the other hand, was in the Safari browser which ships on all Apple computers.

Gmail Manager Work-around fix for new Gmail

 

recently the Gmail team has been working on a structural code change that we’ll be rolling out to Firefox 2 and IE 7 users over the coming weeks (with other browsers to follow). You won’t notice too many differences to start with, but we’re using a new model that enables us to iterate faster and share components (we now use the same rich text editor as Groups and Page Creator, and the Contact Manager can be seen in several Google apps). A few other things you will notice are some new keyboard shortcuts and the ability to bookmark specific messages and email searches. One side effect of this change is that if you’re using third-party Gmail extensions, they’re likely to stop working. And that is the case for Gmail manager, because this extension no longer shows new messages.

But there is quick fix before the new version:

find your profile folder
browse to the extensions directory
open the folder named {582195F5-92E7-40a0-A127-DB71295901D7}
open the components folder
Open “gmServiceGmail.js” in your favorite text editor (notepad)
Use the find feature to the following text: “?search=inbox&view=tl&start=0&init=1″ (without the quotes)
Append “&ui=1″ to that text (again, without the quotes)
Save the file, and then restart Firefox! It should now show your unread messages!

Hope that helps someone!
