How to Enable / Disable XAMPP mod_rewrite

noreply@blogger.com (James) — Thu, 11 Aug 2016 17:44:00 +0000

For any reason if you need to disable/enable XAMPP mod_rewrite (Enabled by default) , then below are the instructions on how to enable .htaccess mod_rewrite in XAMPP.

1. Go to the directory of installation C:\xampp\apache\conf (default) or your installation directory:\xampp\apache\conf

2. Open and edit httpd.conf in a text editor

3. To disable find the line which contains

LoadModule rewrite_module modules/mod_rewrite.so

and (comment) change to

#LoadModule rewrite_module modules/mod_rewrite.so

4. Find all occurrences of

AllowOverride All

and change to

AllowOverride None

I think it appears 2 or 3 times on the configuration file.

5. Restart xampp

That’s it , Now mod_rewrite is disabled. To enable it just follow the instruction in reverse order.

Some easy ways to boot the computer faster

noreply@blogger.com (James) — Thu, 11 Aug 2016 12:19:00 +0000

Slow boot speed is a common problem that a user faces on a daily basis while using computers. This problem can be occurred in computers without virus.

You do not have to worry about such problems. Ways to solve this problem is simple.

Those are:

Keep the Desktop Clean

The easiest way to reduce boot time is to keep your desktop clean. The more files, folders, and programs on computer desktop the longer boot time. You may think that a little folder on the desktop is nothing, but it creates pressure of your computer's boot sequence as well as on RAM and slows down the whole process. However, You do not need to remove everything from the desktop. You can pin your favorite programs on the task bar.

Stop Unnecessary Start Up Programs

Some applications start automatically while the computer is turning on. This is another reason behind longer boot time. So, stop unnecessary start up program.

Clear Temporary Files

Delete the cache and cookies from browser and remove temporary files from your computer.

Android getDrawable() deprecated API 22 Alternative

noreply@blogger.com (James) — Thu, 11 Aug 2016 12:14:00 +0000

There are several options to handle getDrawable() deprecation (the right and future proof way), depending on which kind of drawable is being loaded:

A) Drawables without theme attributes

ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

For unstyled drawable the old way. This is probably what is needed.
Please note: ResourcesCompat.getDrawable() is not deprecated!

B) Drawables with theme attributes

ContextCompat.getDrawable(getActivity(), R.drawable.name);

For a styled Drawable as the Activity theme instructs.
C) Drawables with theme attributes from another theme

ResourcesCompat.getDrawable(getResources(), R.drawable.name, anotherTheme);

Explanation:

Android 21 (5.0 Lollipop) introduced some new theme attributes such as android:colorAccent that modify the appearance of drawables that hold references to those new theme attributes values.

The AppCompat library handles pre and post-Lollipop drawable styling for you.

If the deprecated getDrawable() method is used to obtain a drawable resource with theme attributes, A partially-styled drawable and a logcat warning will come as output. It can be seen in API 22 android.content.res.Resources source code:

@Deprecated
@Nullable
public Drawable getDrawable(int id) throws NotFoundException {
final Drawable d = getDrawable(id, null);
if (d != null && d.canApplyTheme()) {
Log.w(TAG, "Drawable " + getResourceName(id) + " has unresolved theme "
+ "attributes! Consider using Resources.getDrawable(int, Theme) or "
+ "Context.getDrawable(int).", new RuntimeException());
}
return d;
}

Comparison Between Android & IOS

noreply@blogger.com (James) — Mon, 06 Jun 2016 07:14:00 +0000

Android and IOS are the most popular mobile operating system nowadays. Sometimes it's became so confusing to choose one of them. Here a comparison has been made so that it become easy to choose one of them.

Keys	Android	IOS
Type	Mobile OS	Mobile OS
Licence	Apache License 2.0 GNU GPL v2 for the Linux kernel modifications	Proprietary software except for open-source components
Developer	Google Open Handset Alliance	Apple Inc.
Written in	C (core), C++, Java (UI)	C, C++, Objective-C, Swift
OS family	Unix-like	Unix-like, based on Darwin (BSD), OS X
Source model	Open source and in most devices with proprietary components	Closed source
Initial release	September 23, 2008; 7 years ago	June 29, 2007; 8 years ago
Platforms	32- and 64-bit: ARM architectures, x86, x86-64, MIPS and MIPS64	64- and 32-bit ARM architectures: ARMv8-A (iOS 7 and later) ARMv7-A (iPhone OS 3 and later)
Kernel type	Monolithic (modified Linux kernel)	Hybrid (XNU)
Default user interface	Graphical (Multi-touch)	Cocoa Touch (multi-touch, GUI)

The above comparisons are only the technical comparisons. According to the User Experience it is seen that android is a bit slower then IOS . The reason behind this is, Android uses java and java is excellent but a bit slow. On the other hand IOS use a language named swift which has been designed for speed. Android gives you the opportunity to tweaking your OS in every ways whereas you cannot even use IOS without Apple's permission. If you need a independent mobile os with unlimited features and you will consider the speed a little bit then Android is here but if you think that you need a OS that will give you ultimate speed and you will consider some feature limitation then IOS is here. This is my opinion. May be your opinion is different then mine and Always the Choice is Yours.

noreply@blogger.com (James) — Fri, 22 Apr 2016 16:09:00 +0000

After clicking the Send button if you think that there was a mistake in the email and now you want to undo send or delete the mail. If you are a Gmail user, then you can get at least a little bit of time to get back the message that you have sent. 'Undo Send' is a feature of Gmail that gives the facility to stop/delete mistaken e-mail immediately after cliking send button. Gmail Lab have included this feature six years ago, but it was experimental. However, If you want to activate this feature, then follow the steps below.

Gmail Sign (login).
Click the gear icon in the upper right hand corner of the screen.
Select Settings.
Go to the Undo Send part under General tab.
Click Enable Undo Send-.
Select duration from the list.
By clicking on the Save Changes button located at bottom of the screen save the new settings.
From now each time after sending an e-mail you will see the "Undo button" next to the text "Your message has been sent".
