I really love it, and I read somewhere that it had a terrific graphics processor.. I’m very much into that kind of stuff so las Saturday I decided to write a little Mesh loader.

Here are some of the results:

It seems nice, at least I think so. It is Wavefront’s file format (.obj)

The monkey is Blender’s basic figure, Suzzanne.

In order to use your model with my mesh loader you need to remember a few things when exporting in Blender.

You need to:

Triangulate your model (it can be don from the export Wavefront OBJ dialog), this is a MUST.

Export normals. This is just in case you want lighting to work, if not you can just not export without normals, you’ll notice in that case that you get it with just a color that changes depending on the position you put your finger.

If you want the code.. you can get it here!!  MeshLoader.zip

I would work on the material loader, but I want to write a OpenGL ES 2.0 JNI Library (I am very interested in GLSL).

I know that on android 2.2 this will be available on directly in the Java API… but it seems that Android 2.2 on mainstream is going to take a while…

Meanwhile.. you can expect to have some of my API in github as soon as next week (hey.. I also have a job )

Just one thing, the salt needs to be of EXACTLY 8 characters, if it could be bigger my problem would be solved

SMD5(password, salt):
    hash = MD5(password + salt)
    return '{SMD5}' + BASE64(hash + salt)

Why? Well, it seems like growing up means to become a manager, that was my plan, but the truth is I don’t see myself like that and it’s frightening to think that I’m going to get bored someday (I think it’s important because that’s what I’m gonna do MOST of my time for the rest of my life).

Am I going to get bored? Should I do something different in life?

Before trying to answer that, I should check things that I love from current or past experiences.

From my current job there are two things that I love.

The chance to design great solutions.
Finding out how to do complicated but little things.

From school:

• Mathematics!
• Learning how things work
• Once again finding out how to do little but complicated things.

What I don’t like:

About my current job:

• Most of the apps I write are essentially just databases
• I spend most of the time fixing stuff, explaining stuff or writing documents.

What I don’t like about school:

• Administrative courses
• Bad teachers
• Homework

It seems I’m the academic type, I’m not really sure yet, and I’m going to keep working a while longer, and I’m going to experiment different types of jobs, but I think in the end.. I’ll finish studying a PHD somewhere…..

Just maybe… I dunno yet..

I’ve lived for 22 years, throughout those years… I’ve always had questions.. I’ve always tried to find out how the world should be, how to make it a better world.

I don’t like to judge in advance, I like to believe in people…

I’m a person who likes to analyze everything, and likes to think of better ways of doing things… I enjoy of finding problems and to imagine solutions…

I’m someone who likes  to learn new things, and to try everything… I believe the world is full of incredible things to offer…

I believe I’m full of possibilities and I think there is much to know about myself.

I’m naive.

All of the previous statements describe me, but they don’t answer an important question… who am I?

I think today I started to answer that question…

I’m Eduardo Díaz, a little kid who is anxious to go out and meet the world, who wants to be everything in life, who wants to change the world…

That’s me… and now that I know I’m ready to grow up and start thinking about the real important question..

WHAT TO DO WITH THE LIFE THAT HAS BEEN GIVEN TO ME?

I don’t believe it’s going to be a a short or easy journey… but it is a journey I have to make… and I hope I won’t forget who I am, I hope I can still carry on with my ideals… I can just promise I’ll do my best…

I also tried my first kebab

I was about  going out from a job and going to school fulltime!

I started jogging (which I am not doing now, and I should)

I was about to travel to Canada..

I don’t know what else, but I think it would be interesting to answer the same question in a year… Seems like a lot is going to change this year…

BTW, have you ever been asked how many piano tuners are there in the USA?

Beats me, I don’t know

What it does is send a command string through the socket, the command gets executed on the other end and returns the answer.

import os
import socket
 
host = "127.0.0.1"
port = 1234
 
def execute(command):
    result = ""
    args = command.split(" ")
    if args[0] == "cd":
        os.chdir(args[1])
        return "Dir changed"
    pipe = os.popen(command, "r")
    for line in pipe.readlines():
        result += line
    return result
 
def get_and_obey():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((host, port))
    while True:
        command = ""
        while True:
            temp = s.recv(1024)
            command += temp
            if not temp or len(temp) < 1024:
	        break
	if command == "exit":
	    break
        result = execute(command)
	if not result:
	    result = "Error with command"
        s.send(result)
    s.close()
 
if __name__ == "__main__":
    get_and_obey()

import os
import socket
 
host = ''
port = 1234
 
def recv_and_command():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((host, port))
    s.listen(1)
    conn, addr = s.accept()
    print "Receiving and commmanding", addr
    while True:
        command = raw_input("remote>>")
        conn.send(command)
	if command == "exit": 
	    break
        result = ""
        while True:
            temp = conn.recv(1024)
	    result += temp
	    if not temp or len(temp) < 1024:
	        break
        print result
    s.close()

I want to write a version that uses the http protocol, and maybe someday I’ll write my own http server

In this case we are simulating three devices:

• An internal memory, written in objective C.
• An LCD device, written in python.
• A joystick driver, written in python.

The interface to the programs is through the memory, and we can add the configuration through a simple file:

[dataflash0]
lib = at91sam9260
sym = dataflash
model = objc
base = 0
size = 2097152
 
[control1]
lib = at91sam9260
sym = Control
model = python
base = 8587830276
port = /dev/input/js0
 
[lcd]
lib = at91sam9260
sym = LcdMx
model = python
config = images.cfg
base = 4294963716

#include <controller.h>
#include <lcd.h>
 
void main() {
	unsigned char *lcd = (unsigned char *)4294963716;
	unsigned char *control1 = (unsigned char *)8587830276;
	unsigned char *control2 = (unsigned char *)8587830272;
	int i;
	char id1;
	char id2;
	char move1;
	char move2;
	id1 = createObject(lcd, 1, 1, 1);
	id2 = createObject(lcd, 2, 1, 1);
	put_char('0' + id1);
	put_char('\n');
	put_char('0' + id2);
	put_char('\n');
	while(1) {
		move1 = readControl(control1);
		move2 = readControl(control2);
		put_char('0' + move1);
		put_char(' ');
		put_char('0' + move2);
		put_char('\n');
		if(move1 != 8)
			move(lcd, id1, readControl(control1), 1);
		if(move2 != 8)
			move(lcd, id2, readControl(control2), 1);
	}
}

I dream of a world where people really know themselves, their dreams, their abilities, their capabilities and also believe in themselves. Imagine a world where you are free to have your beliefs, your opinions and your ideas without fear.

In such a world, everyone would follow their dreams to the last consequences. In such a world people would regret doing things, not letting things go..

But I don’t believe in such a world, I don’t believe it’s possible. It’s not human’s nature. I can just dream of it, and dream of becoming a citizen of my world… meanwhile I’m just a radical dreamer.

So here’s my list of interesting things that I want to try:

• Notion Ink Adam

A new tablet, it looks very very interesting (not like the iPad), it features an ARM processor by nVidia, the nVidia Tegra 2. It is a Dual Core ARM Cortex with integrated video controller, it must be pretty good as it supports HDMI.

I want to get my hands into one of those processors! And I have a new personal project, writing the device simulators of the nVidia Tegra for armycreator (part of my thesis project). It will go very slowly but hopefuly someday I’ll be able to run Android on armycreator.

• HTC Desire

Another device which I’m very interested in because of my obsession with ARM processors. It has an awesome ui, based on Android. I must admit.. I didn’t believe in Android at first, but at least to me it looks very very interesting.

• Cassandra

As it looks to me the future of databases. Cassandra is an apache project which aims to build a distributed database,  it features high availability, and it reduces bottlenecks as every node of the cassandra cluster has the same information.

Based on Amazon’s Dynamo and Google’s BigTable it looks like a very good option for a high available, high performance database.

• Lustre

Sun’s distributed fs, the wikipedia states that 15 of 30 of the fastest clusters in the world use lustre. I looks promising and a major improve over older distributed fs.

Maybe I’ll get an opportunity to work with lustre and cassandra in a project here at javanes, if so.. I’m looking forward to it!

As for the ARM projects… I don’t think I’ll have enough time, if you want to help you’re free to do it, contact me and I’ll help you too.
