How to stop VLC Building font cache again and again

2012-10-30T00:30:00.001+05:30

VLC is one of the best media players available to view videos and listen music. Vlc is having good functionality but sometimes you might be annoyed due its repeated process of building font cache at the time when you start your VLC to play any video files that have subtitles or even while displaying name of the file being played.

What does Building font cache mean ?

Generally whenever VLC is loaded it scans for fonts in the system that are required to display title or subtitles of the movie being played. It finds the fonts and copies it in the cache memory for any further reference.

As it scans whole system it may take time to do this process, but most of users like me gets annoyed by constant rebuilding font cache process, so here's the solution of this problem.

Steps to stop VLC Building font cache.

Goto Tools menu and select Preferences or press ctrl+p.
Select "All" from show setting tab in the bottom left corner.

select "videos" from available list of options and select subtitles/osd option from videos tab
Now select "Dummy font renderer" from Text rendering module
Press on save button.

That is all you need to do to stop VLC to search fonts from the system again and again.The next time you open VLC, you will be free from that annoying cache-building dialog.

2012-04-10T11:21:00.001+05:30

Sometimes we open lot of Windows applications to get our work done. But the main task starts after completing work. The most hectic task is to close those Windows which were opened while working. Closing them one by one involves lot of time and when we are in rush we directly close our Windows which may result in loss of data.

The point is what to do? Even if we use task manager we have to click on ‘End Now’ option. We usually use Alt+F4 combination, but sometimes it also doesn’t work. Tool known as Close All can be used to solve hectic situation.

Close All is a portable tool that allows to close multiple Windows with one click.When we install this application, it creates a small icon of the tool in Quick Launch bar as shown in the screenshot below.

Installing Close All:-

Close All Windows is a very simple utility that doesn’t require installation. No settings are stored in the Windows Registry or file system. Just follow the steps below to set it up on your computer.

Download the ZIP archive and extract it on your hard drive.
Open the extracted folder, right-click CloseAll.exe and choose Send To -> Desktop (create shortcut) from the context menu.(If system you are working is 64 bit then use x64 folder)
Switch to the Desktop and rename the created shortcut to “Close All” or whatever you want.
Now you can drag this shortcut to the Quick Launch Bar or to the Windows 7 Taskbar for quick access.

Advanced Options:-

If you want to prevent certain applications from being to be closed by Close All, you can add a simple exclusion list to the CloseAll.exe command line.

Right-click the shortcut and choose Properties from the context menu:
Go to the Shortcut tab, Target and add -x="app-to-exclude.exe":
You can separate multiple values with “|” (pipe),
example: -x="vlc.exe|firefox.exe|msnmsgr.exe"
Click OK to save the shortcut properties.

Jailbreaking and its Basics

2012-03-04T20:09:00.001+05:30

What is Jalibreaking?
Many smartphone, tablet, and game console makers include a layer of Digital Rights Management (DRM) software on their products. This DRM exists either to limit the software you can run on it, or is there for security reasons. Jailbreaking is the process of hacking these devices to bypass DRM restrictions, allowing you to run "unauthorized" software and to make other tweaks to your operating system.

Technically, jailbreaking can be thought of as the process of installing "a modified set of kernel patches (the kernel being the supervisor of the operating system) that allow you to run unsigned code. It also gives you root-level access, which is otherwise unavailable. The term "root" comes from UNIX, where it is the superuser account that has unrestricted rights and permissions to all files. This provides you with added flexibility, but it also has some inherent dangers.
Why to jailbreak your idevice?

One of the main reasons for jailbreaking is to expand the feature set limited by Apple and its App Store while the other is to customize the look of your device.Most jailbreaking tools automatically install Cydia, a native iOS Advanced Packaging Tool(APT) client used for finding and installing software for jailbroken iOS devices. Since software programs available through Cydia are not required to adhere to App Store guidelines, many of them are not typical self-contained apps but instead are extensions and customizations for iOS and other apps.

Why not to jailbreak your Idevice?

Once you do it, you're on your own. You may have voided your warranty, so you can't rely on Apple, AT&T or Verizon, to fix any problems you encounter. All of the applications that jailbreak your phone are unauthorized and could damage or completely disable your iPhone. Your smartphone could end up as nothing more than a very expensive useless device.

Is jailbreaking legal ?
It depends on who you ask, as far as the US government is concerned, it is legal to jailbreak your smartphone. In 2010, the Digital Millennium Copyright Act (DMCA) recognized the arguments of the Electronic Frontier Foundation (EFF, the international non-profit digital rights advocacy organization) to add phone jailbreaking to a list of exemptions to anti-circumvention provisions.

On the other hand, Apple and some other companies, continue to plead with regulators to outlaw the practice. The best they can do at this point is tell users that jailbreaking defies their terms of use and voids the warranty. In other words, while you don't risk being arrested just for jailbreaking, don't expect any help from the Apple Store genius when your hacked iPhone has a problem.
