Play Low Quality Videos in Gome Flytouch

One of the common problems of Gome Flytouch is its inability to play high quality videos. Here is a trick by Kiarov for converting videos to a lower quality in order to be playable - Gome Flytouch Video Encoding Tutorial. Do not forget, you must have your tablet overclocked to 400MHz.

The software used for conversion was HandBrake but you can use any converter of your choice. The converted videos work well with Meridian Player.

Here’s the settings:

Type: MP4
Size: 480x320
Video Bit Rate: 384 kbps
Frame Rate: 25 fps
Video Encoder: XVid
Audio Encoder: AAC
Sample Rate: 44.1 KHz
Audio Bit Rate: 64 kbps

G Sensor and Camera Fix for Gome Flytouch

Some Gome Flytouch tablets have their G sensors and cameras inverted by default. There are two ways to fix these.

1. If you’re creating your own firmware, it’s better to include the fix right on the scriptcmd file.

For the G sensor, add this line:

setenv gsensor_axis 0,-1,1,1,2,1

and for the camera:

setenv camera_rotate 270

2. If you had your device rooted, just execute the commands above on any Android terminal as root.

Android 1.6 Firmware Default Wallpaper

The default wallpaper file is:

/data/data/com.android.settings/files/wallpaper

It is a JPEG file format without the .jpg extension.

My Android Splash Screen

I just want to share my Android Splash Screen. Credit goes to the original artist. I just modified some part of it.

If you have an 800x480 pad, make sure your bitmap is 24-bit and of course the resolution must be 800x480.

Active Directory with JXplorer

For folks who do not read the manual. If you encounter this error using JXplorer:

[LDAP: error code 1 - 00000000: LdapErr: DSID-0C090627, comment:
In order to perform this operation a successful bind must be completed
on the connection., data 0, vece]

Do not use your login name. Use your full name instead.

On an obsolete road

I have already forgotten these things.

1. Inner join versus outer join
2. Simple select statement for getting the max value of a column + another column
3. Definition of Object Oriented programming
4. Exact figure of the limitation of HTTP GET.
5. Differences between GET and POST.
6. The default method of an HTML form when submitted.

I have made time to review them. Here they are.

1. Inner join will return matched results between two tables while outer join will return all regardless if there is a match or none between the two tables. Here’s a good article by Jeff Atwood, A Visual Explanation of SQL Joins.

2. Given a table Person with two columns, Name and Age. To get the eldest,

SELECT Name, Age FROM Person WHERE Age = max(Age);

3. Object oriented programming is a programming paradigm that uses objects. These objects consist of fields, methods and their interaction.

4. 256 characters.

5. Given the size limit of GET, POST is used to overcome that. POST is used if you want to submit data with non-ASCII characters. If you want to hide data you’ll prefer POST than GET since it hides hidden fields in the URL but it’s not enough since you can view the source or use browser debugging tools such as FireBug and Chrome Developer Tools.

6. If you have an HTML form with no method defined, GET is the default.

There goes my hopes and dreams. The road less traveled.

Casting to a Boolean in JavaScript

I came across with this expression,

button.enabled = !!enable

!! is just a double not. This is just obscure.

HTML5 Web SQL Database

HTML5 has a bunch of cool APIs. In one of my previous posts, I have written a simple demonstration of the Web Storage JavaScript API. In this post I will be showing another demonstration, the Web SQL Database JavaScript API. What is so fascinating about these APIs is they are “crash-safe.” Now you can lessen the load of your web servers and perform SQL tasks like, sorting, joining, etc. on the client side.

Removing while Iterating a Collection in Java

Let us say you have a list and you want to remove items while iterating through it if a certain condition satisfies.

for (Object object : listOfObjects) {
    if (isConditionSatisfied) {
        listOfObjects.remove(object);
    }
}

What is wrong with this code above? Try it and you will get this,

Exception in thread "main" java.util.ConcurrentModificationException

You might want to do this instead,

Iterator<Object> iterator = listOfObjects.iterator();
while (iterator.hasNext()) {
    Object object = iterator.next();
    if (isConditionSatisfied) {
        iterator.remove();
    }
}

Have a nice day.

HTML5 Web Storage

Here is a simple demonstration of HTML5’s Web Storage. The code is quite straightforward. One thing to experiment is after entering any string and hitting save, try closing the browser entirely and opening it again visiting the same page to see if the data persisted.

Click [here] for the demonstration.

Just for fun!

It has been a while since I have written something about Javascript. You need to copy and paste this to your browser’s address bar to see how it works.

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200;
DI=document.getElementsByTagName("a"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style;
DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=
(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',50); void(0);

Enjoy!

Performance of null checks in Java

Which one is faster? a == null or null == a?

This is the method of the former.

    public static boolean firstNullCheck(Object a) {
        if (a == null) {
            return true;
        }
        return false;
    }

and the method of the latter.

    public static boolean secondNullCheck(Object a) {
        if (null == a) {
            return true;
        }
        return false;
    }

Here’s the disassembly of the former.

public static boolean firstNullCheck(java.lang.Object);
  Code:
   0:	aload_0
   1:	ifnonnull	6
   4:	iconst_1
   5:	ireturn
   6:	iconst_0
   7:	ireturn

and the disassembly of the latter.

public static boolean secondNullCheck(java.lang.Object);
  Code:
   0:	aconst_null
   1:	aload_0
   2:	if_acmpne	7
   5:	iconst_1
   6:	ireturn
   7:	iconst_0
   8:	ireturn

The former saves you a bytecode. Anyone who can explain further since I am not sure whether if_acmpne is faster than ifnonnull?

Google over SSL

If you do not want your search queries to be compromised, use Google SSL. However, there is one thing I discovered though, if you click on a cached link, it’s not encrypted, it goes back to HTTP from HTTPS making the protected search useless. Just be aware.

Importance of daily meetings

Why are daily meetings important? Yes I know what you are thinking, to check if the schedule is on target, to spot showstoppers, roadblocks and whatnots. But aside from those, there are things that make daily meetings rewarding.

Let’s face it, some people (including me) find it hard oftentimes to achieve a certain level of focus at work especially when multitasking is inevitable. Meetings will remind us of our commitments infront of our peers. Since most of us will be ashamed of not making any progress, it will trigger ourselves to do something about it.

In my opinion, having daily meetings typically before the shift starts will help a lot of peers suffering from bad habits - procrastination. It is one way of invigorating those who have not found their way out yet.

“Keep each other in the zone, what are teammates for?”

Endianness of Java

In Java, multibyte data items or streams are stored in big endian order.

Using Java to write bytes directly to the wire will require byte-order transformation if the recipient talks in little endian. The same is true if you are reading directly from the wire from a sender who talks in little endian.

If you are using a byte array wrapped in ByteBuffer,

byte[] data = new byte[] { 12, 19, 83, 05, -05,  55, -55 };
ByteBuffer byteBuffer = ByteBuffer.wrap(data);

Transforming from big endian to little endian is easy,

byteBuffer.order(java.nio.ByteOrder.LITTLE_ENDIAN);

If you are unsure of the endianness of the underlying platform, just invoke the native order method.

java.nio.ByteOrder.nativeOrder();

Aside from streams, operands in classes that are above 1 byte in size are in big endian order.

Java Lambda Expressions / Closures

Lambda expressions are just (anonymous) functions.

f(x) = x can be expressed as x→x
f(x, y) = x*x + y*y can be expressed as x, y→x*x + y*y

In simple Java terms,

1. Return an int 23 with a void argument

int j = { => 23 }.invoke();

2. Closure with 1 argument, convert 23 kilograms to pounds

double j = { double kilograms => kilograms*2.2D }.invoke(23);

3. Closure with 2 arguments, get the sum of the 2 squares

int squareSum = { int x, int y => (x*x) + (y*y) }.invoke(2,3);

4. Closure returning an instance and invoking an instance method

{ new RocketLauncher() }.invoke().fire();

Every time a closure is created at compile time, an interface is automatically created for each expression having an invoke method with a signature depending on the number of arguments, then an anonymous subclass of this interface is constructed.

Enjoy!
