Latest FireFox 39.0 LEAKS memory

FireFox

I don't know about you, but the latest Firefox is not working like the previous versions use too. I am running Firefox 39.0 on Windows 7 and it crashed on me few times. If not, it crawls down or completely blacks out so much that I find myself having to restart FireFox every 15 minutes. Well, I found out that it is LEAKING MEMORY really really really really reallllllllllllllllllllllllllllllY BAD. It leaks memory when running idle without going to any website for GOD SAKE. So, I went online for solution and many people have said that they are not having any problem. And then, there are those who are having problem just like me. It turns out that this memory leak has something to do with FireFox Addons.
 
 So, I disabled all the addons on my FireFox. It has helped a lot, but it still crashes or blacks out only that it takes longer.

When I run Firefox 39.0 with all the addons enabled, its crashes with memory at somewhere 1.5GB. And without any addons enabled, it crashes with memory at somewhere 500MB.

What is going on FireFox? Oh well, I guess good things can't last forever.

How to mount your encrypted USB hardrive?

If you are running Linux OS like Ubuntu and you recently try to mount your encrypted USB hardrive, then you probably got error message "Unable to mount." If so, then you probably don't have cryptsetup utility installed on your system. It is needed to encrypt and decrypt device.

To install the cryptsetup, open terminal window and enter the following command as you see it exactly:
sudo apt-get install cryptsetup

Once it successfully installs, then you should be able to mount your USB hardrive after entering your passphrase using GUI or terminal.

How to fix No Sound in Windows 7 Home Premium Edition?

Windows 7 Home Premium Edition No Sound Fix

Before I give you my solution to Windows 7 Home Premium Edition No Sound Fix, lets make sure we are on the same page.

My computer system is Compaq Presario SR1817CL Desktop PC. For audio output, I have AC'97.

When I first installed my Windows 7, everything went well except for the sound. I went all over the Internet in search of fixes and there are plenty of them with different approaches and techniques. Being new to Windows 7 for the first time, I tried my best to follow their instructions and steps but nothing helped. In the process I may have screwed up my Windows 7 installation. However, all along there was a very simple solution to my sound problem.

After messing around with Windows 7 for about 2 hours, I learned that you CAN'T trust what Windows 7 says that it did or is doing. You should always try to enable or disable a process or function to see if the system is STILL having problem. What do I mean by that? Well, since my system was having sound problem, I saw the typical signs.

no-sound-in-windows-7-fix icon

System message: No Sound Device Installed

Windows 7 itself searched online for sound driver for my AC'97 output and it kept reporting that it can't find any driver. I tried to look for sound driver for my computer on the manufacturer website myself and still can't install it. So, I ended up shifting through more websites and then I came upon a piece of information on Windows 7. That is even if your system says no sound driver found or can't update driver, try enabling and disabling the component and then try updating for the driver.

So, this is what I did. I opened my control panel-->device manager. There in the tree view window look for device in the list with yellow warning triangle. Yours might be under OTHERS or Sound, Video and Game controller category. Right click on it. In the popup menu first click on DISABLE and then ENABLE. At this point, Window 7 might start to automatically search and download driver. If not, click on the UPDATE DRIVER SOFTWARE option. Then, another window might open asking if you want to yourself search or the system search online for driver. Just have the system search for the driver. At this point, it should successfully download and install the sound driver and you don't even have to reboot your computer system. For me as soon as it got done installing the driver, my speaker icon red X disappeared. I HAVE SOUND NOW!!!!!!!!!!!

This is what I did and it worked for me and I hope it does for you too. Thanks for visiting my blog.

Cheers!!!!!!!

How to install VitrualBox Guest Addition (VBoxGuestAdditions.iso) on Linux (Ubuntu)?

Honestly, I have to say that I never ever spent this long trying to install a simple ISO file before. I went through so many self-help forums and websites still couldn't get the Guest Addition installed, but there is obviously a simple solution, which I overlooked. The reason I wanted to install guest addition to my VirtualBox was because my virtual machine wouldn't go fullscreen but acted like it was only 1078x768 or something.

Here are the steps in installing Virtual guest addition (VBoxGuestAdditions.iso) on Linux (Ubuntu). I am using VirtualBox 4.3.10 for Linux.

1. Before you begin, you must have already created a virtual machine using an operating system of your choice as shown below. I installed Linux Elementary OS.

   

   Snapshot of Virtual Machine

2. Start your virtual machine(VM) by clicking on the start button. Once it is up and running click on the Devices pull down menu on your VM. In the bottom of that pull down menu, you will see an option "Insert Guest Additions CD Image..." Click on it.                                                                 
   
3. At this point, VM will either tell you that you don't have Guest Additions Image and if you want to download it now. Just go ahead and click on the download button, but if you still have problem, then you need to download Guest Additions ISO image yourself. Then, follow this step. If everything went well you probably won't see anything or even a confirmation saying that Guest Additions is installed. What that means is that it didn't install guest addition yet but you have only mounted the ISO file. Now, if you were like me who ran into "Can't mount Guest Additions Image," then you probably already have Guest Addition Image opened or linked to your VM. Then, you should move on to the next step, but make sure VBoxGuestAdditions.iso is linked to your VM by going to VM->Settings->Storage->Store Tree Listbox. Another way to verify that you have successfully mounted your Guest Additions ISO file to your virtual machine is by opening the VM folder and file explorer like dolphin. Once it is opened, you should see VBoxGuestAdditions.iso listed on the left hand side. Don't close the dolphin file and folder explorer yet. Leave it open for you will be using it in the next step.
4. Now, click on the VBoxGuestAdditions.iso mounted image listed in the left-hand side in the Dolphin files and folders explorer in your VM. When you do that, on the right-hand side Dolphin will display all the files and folders within VBoxGuestAdditions.iso. You will see bunch of .exe files and linux related files. If you are like me running Linux on your VM, then you should look for VBoxLinuxAdditions.run in the list.
5. Now, VBoxLinuxAdditions.run is the file you need to run to install Guest Additions ISO image for your VM. To run the file, first you need to find its absolute path to the file. So, right click on the file and click on properties. Just copy the direct path shown on that popup window. Then, open a terminal window. There type in the following after the prompt sudo ./your-direct-path-to-the-file/VBoxLinuxAdditions.run. Then, hit enter. At this point, it will ask you to enter the password. After that, it will run through the installation.
6. After installing VBoxGuestAdditions.iso, you will need to shutdown and restart your VM for Guest Additions to be applied to your VM. That's all. Now you should see your VM fullscreen.

How to fix no sound on Ubuntu 14.04, 13.10, 13.04 and Older versions

I am a huge fan and user of Linux operating system (OS) especially Ubuntu. And like any other Linux OS, I often find myself trying fix something or other after installing the OS. In particular, I would find myself trying to fix NO SOUND problem. I have found several steps that can help anyone having NO SOUND problem with their Linux OS.

1. Check your volume. By clicking on the speaker icon on the toolbar or opening system setting->Sound Settings, you should be able to adjust your system volume. Sometime user tends to over look this obvious mistakes.

   

   Volume Setting

   

   Linux Volume Setting

2. Check your ALSA Mixer.
   PulseAudio controls underlying ALSA-level volume controls. To change the ALSA-level volume controls directly, you can do the following:
   Open a terminal. (The quickest way is the Ctrl-Alt-T shortcut)
   Enter “alsamixer” and press the Enter key.
   You will now see a user interface like below.
   
   

   

   ALSA Mixer

   
   
   In this user interface, you can do the following:
   
   
   1. Select your correct sound card using F6 and select F5 to see recording controls as well
   2. Move around with left and right arrow keys.
   3. Increase and decrease volume with up and down arrow keys.
   4. Mute/Unmute with the “M” key. An “MM” means muted, and “OO” means unmuted.
   5. Exit from alsamixer with the Esc key.
   
   A caveat here: When you mute or unmute something, pulseaudio might pick it up and mute and unmute other controls, as well as PulseAudio’s main mute.
   
3. Reinstall Alsa and Pulse Audio.
   Try to reinstall pulse audio and Alsa, open terminal and enter the following commands:
   
   Purge Alsa and Pulse audio using the command:
   

   sudo apt-get remove --purge alsa-base pulseaudio

   Now install again Alsa and Pulse Audio:
   

   sudo apt-get install alsa-base pulseaudio

   Then, reload Alsa:
   

   sudo alsa force-reload

   
   Done. Check now the sound if it is working, if not, try step 4.

4. Install Ubuntu Audio Development Team Driver

   Note: This PPA is not updated to 14.04 yet.
   
   Upgrading your sound drivers may fix the nosound issue, you will need to make sure to uninstall the previous override before trying a new one.
   Open terminal and enter the following PPA:

    sudo add-apt-repository ppa:ubuntu-audio-dev
    sudo apt-get update
    sudo apt-get dist-upgrade 

    
5. If all else fails, try the following command.
   
   

   alsactl -F restore 

Hope this helps someone. That's all for now....Cheers...

How to change Blogger line spacing?

Blogger Line Spacing

I recently needed to change the line spacing for my blog. Everywhere I searched online, their information seemed to be outdated. In my quest to change the line spacing for my Blogger blog post, I figured out how to do it. So, I want to share this new information with the world.

Line spacing in blogger blog:

How to  Change Line Spacing in blogger blog :

step 1 : Go to Dashbord
step 2 : click on template 
step 3 : click on Edit HTML

Search for line-height within #main in that template html code. You need to change line-height number as you like it. The higher you go the more spacing there will be between lines of a main body of your blog. It is by default set for 1.5em. You might want to change it to 1.8em. Just change the number and leave the "em" at the end.

#main {
  float: $startSide;
  width: 460px;
  margin-top: 20px;
  margin-$endSide: 0;
  margin-bottom: 0;
  margin-$startSide: 0;
  padding-top: 0;
  padding-$endSide: 0;
  padding-bottom: 0;
  padding-$startSide: 1em;
  line-height: 1.9em;
  word-wrap: break-word; /* fix for long text breaking sidebar float in IE */
  overflow: hidden;     /* fix for long non-text content breaking IE sidebar float */
  }

 

Apple Will Let Mac Users Try Out OS X Betas (Finally!)

Apple OS X Beta

Good news for early adopters. Will iOS be next?

If you’ve got a Mac and like trying out new software, Apple has a proposition for you. Join its new OS X Beta Seed program, and you’ll be able to download free test versions of future editions of OS X from the Mac App Store, before they’re released to the general public.

As with all beta programs, what’s in it for the software developer in question is real-world testing. Apple will be able to get feedback from program participants while it’s still possible to fix any glitches which turn up.

With any other product and any other company, this wouldn’t be news: It’s the way things work, generally speaking. For instance, Microsoft released a free consumer preview of Windows 8 in February 2012, months before the final operating system shipped in October.

Apple, however, has usually held its betas close to the vest. It’s distributed them to people who pay $99 a year to register as an OS X or iOS developer, but doing so has required those folks to sign an agreement saying they won’t discuss the pre-release software in public.

Actually, that mandate is still in place: As the Verge’s Chris Welch points out, signing up for the Beta Seed requires you to agree that you won’t blog, tweet, share screen shots or otherwise spill the beans.

The Beta Seed site never says that signing up for the program entitles you to get every new version of OS X early. In fact, the only version of OS X it mentions by name is Mavericks, the current major release. So I don’t think it’s a given that Beta Seed testers will get immediate access to the next version after Mavericks when it comes along, possibly at Apple’s Worldwide Developer Conference in June. But it would be nice if they did: It will have major new features, and any further Mavericks updates probably will not.
It’s traditional in stories such as this one to include a stern disclaimer that installing beta software can cause major problems and therefore isn’t for the faint of heart. I guess that’s true. Full disclosure, though: For years, I’ve installed most betas the moment I can get my hands on them. So far, I’ve lived to tell the tale. It may be risky, but it can also be a rewarding experience.

How about iOS? Apple isn’t making any mention at all of its mobile operating system, and it would be a much bigger decision for it to let consumers install such betas. Early versions of smartphone operating systems are far more likely to have crippling problems than desktop ones, and it’s tougher to reverse the process if you regret installing them
 
I can’t imagine that Apple wants to provide tech support for people who install an iOS beta and then discover that their phone no longer functions as a phone. Maybe the company will cautiously provide seeds of very late, almost-done betas–also known by names such as “release candidates,” and typically just about as polished as final software. Here’s hoping.
