Cool math game for Android

I have played a cool math game called "Match The Math" in my Android devices, I have one small smartphone (Galaxy Y) and a 7" tablet.

The game has different adjustments for larger screens as presented in following images, available in Google Play page's of the game: https://play.google.com/store/apps/details?id=com.engcross.matchthemath

The game begins giving you a target and some numbers, your objective is to get the target handling given numbers with math operations.

You should be able to get the target with a unique expression, for example:

Target = 10

Numbers
2 | 3 | 5
25 | x | x

Your solution may be:

2*5  = 10

or

2 + 3 + 5 = 10

or

2*25/5 = 10

or

25/5 + 3 + 2 = 10


Take a look that there is a bar at the bottom of the screen, it's a timer that finishes in 40 seconds, so you have this time to find a solution for your target.

Match The Math  has 4 different levels, each one will be available for playing when you gain enough experience in the easier level. Your experience is known by your ranking of trophies and medals.

You gain trophies and medals when get a good result, if your result is exact you will gain a trophy but if you get a close result, you gain a medal

Following image is a screenshot for a small screen, which has a black area that adjusts to your device and gives you the same experience.

Now, try this cool math game in your Android device, improve your math skills and have fun!

Image processing in batch

I don't have very free time (because I'm doing my mastering qualify), thus this post will be small.

I want show the Phatch.

It's a software for image processing in batch. I don't know how that works, but I believe that it makes the same processing for all images (in a sequence).

Some examples of operations in the Phatch:

• Resize;
• Water mark;
• Smoothing of boundaries;
• Rotate.
  

The Phatch has more complex operations, but I don't use it yet, so I cann't talk about them.

Control the ball with your hands - Game

Using the segmentation of hands, I developed the game Control the ball with your hands.

This a video for show the game:



This game was developed in the Scilab, using the SIVP toolbox, thus it's a simulation algorithm.

I develop games like this because I like it.

If anyone wants talk about this game, or others things, may send me e-mails.

apt-get

De tanto ver tutoriais (on-line) e dicas e eu mesmo tanto falo no apt-get que resolvi fazer um post sobre este software maravilhoso.

O apt-get, da forma que me refiro, consiste em um pacote de vários aplicativos:

• apt-cache
• apt-extracttemplates
• apt-key
• apt-cdrom
• apt-ftparchive
• apt-mark
• apt-config
• apt-get
• apt-sortpkgs
  

Mas de todos estes, acho que só o apt-cache e o apt-get são realmente necessários (talvez o apt-config também, mas eu nunca o usei) corriqueiramente.

Cada aplicativo por sua vez tem seus parâmetros específicos.

Parâmetros do apt-cache:

• add
• dump
• madison
• rdepends
• showpkg
• unmet
• depends
• dumpavail
• pkgnames
• search
• showsrc
• xvcg
• dotty
• gencaches
• policy
• show
• stats
  

Pelos nomes é possível deduzir o que cada um (não necessariamente todos) faz, mas eu costumo usar apenas o search.

Então agora temos o comando apt-cache search *****************, em que a sequência de asteriscos (*****************) representa o que você está procurando, por exemplo vamos procurar algum programa relacionado a P2P:
Observa-se que existem vários programas disponíveis envolvendo P2P.

O apt-cache mostra tanto o nome do programa como uma pequena descrição do mesmo.

Agora para instalar o programa nós usamos o apt-get.

Os possíveis parâmetros do apt-get:

• autoclean
• check
• dselect-upgrade
• remove
• upgrade
• autoremove
• clean
• install
• source
• build-dep
• dist-upgrade
• purge
• update
  

Neste caso, eu costumo usar os comandos remove, upgrade, updade e install.

O remove vai desinstalar o software indicado.

O upgrade vai atualizar o software indicado.

O update vai atualizar a lista de softwares disponível.

O install vai instalar o software indicado.

O apt-get também suporta manipular vários softwares al mesmo tempo.

O comando update é feito da seguinte forma:
Observando que o apt-get precisa da permissão de super-user (sudo, su, root) para ser executado (é só colocar "sudo apt-get update" no terminal).

Estes endereços que aparecem são os repositórios de software, no caso, do Ubuntu.

E para trabalhar com um aplicativo, seja para instalar, atualizar ou remover, é só digitar "sudo apt-get {parâmetro} {nome do software}" no terminal.

No caso, a gente (usuários do apt-get) costuma sudo apt-get update para atualizar a lista de softwares, depois usamos o apt-cache search {palavra relacionada ao software desejado} para identificar o que buscamos (a busca também é feita na descrição do software) em seguida usamos o sudo apt-get install {software desejado} para instalarmos o software nosso de cada dia.

Free Games

Games, or any entertainment aplication, ever are questioned in Free Software, because when someone is talking about GNU/Linux and others free systems other one be the question: "I will can play the game {X}??". So is necessary to cite the incompatibilities between the systems (GNU/Linux and Window$, for example). Sometimes the emulators (as the wine) can resolves the problem, but the games are a big problem to use free software, for domestic users.

Currently exists many free games, or compatible with free enviroments, that are very interesting, for example:

• Nexuiz;
  
• Super Tux (similar to Super Mario of SNES);
• America's Army;
• Open Arena;
• Tremolous;
• Tux Racer;
• Alien Arena;
• The Open Racing Car Simulator;
• Frets On Fire;
• Scorched 3D;
• Mania Drive;
• FreeCraft;
• Cube.

List with many games here.

I believe that money is the biggest complicating for free game developers. But I find some answers to this question:

Publicity - a company can pay to the developers and the game could have advertisements of that, for example a car company (Ferrari, GM, Toyota, etc...) paid for a racer game, and all cars will be of this company.
"Closed" games - the game is free, so the source-code just together the program, but is possible to develop specific hardware to game and to market hardware and software together, or only the hardware, could be possible, too, make a portal with tutorials, tips, upgrades, device drivers, multiplayers games, etc...
Games to mobile devices (or embedded systems) - charge a fee by acess the site, download a program, upgrade, any resource, etc... And yet, the users could be tools to develop levels, for example.

Make money with free games is possible, invent your way!

Other big problem of game market is the developer's (programmers, game designers, graphic artists, etc....) greed, because many developers want be rich with only one game and live of this game forever.

Is better to do some games and make few many in each game than to do one game and make US$ 1,000,000.00 from it.

Today, most players can't pay for expensive games, but they can pay some cents for "simple" games.

Ok, it's all! Come on, let's to develop free games!!
