MIPS Oxford Hello World

Do you love or would like to learn Assembly? Here is your starting code:


## Methark Technology - MIPS Example
## hello.asm
## Registers used
## $v0 - syscall parameter and return value.
## $a0 - syscall parameter-- the string to print.



la $a0, hello_msg
## load the addr of hello_msg into $a0.

li $v0, 4
## 4 is the print_string syscall.

## do the syscall (print the string).

li $v0, 10
## 10 is the exit syscall.
## do the syscall (close the program).

## Data for the program:
hello_msg: .asciiz "Hello World\n"
## end hello.asm

You can download the Spim MIPS simulator from Source Forge.

Have attention with one image

Doesn't matter what you are posting bellow the image, users will look at it and raise the chance of engage your post.

The secret is to use a great title like "How To", a cool image of what you are talking about (on this case Pinterest) and a sort of character that will intrigue the user.

Color palette is to be used or your image will be confusing.

Your life for Science?

Russian next generation Soyuz

Russia has been working on a new spacecraft to get cosmonauts to the moon and Mars.

Now, the Russian Space Agency revealed images of the new, unnamed spacecraft, which has been under development for around a decade.

It looks remarkably similar to Orion – Nasa's new spaceship designed to carry humans to an asteroid, and eventually to Mars.

It is designed to replace Soyuz-TMA that carries astronauts and cosmonauts to the International Space Station.

RSC Energia says it will test it over the next few months, which the first unmanned orbital test flight of the new spacecraft scheduled in 2021.

Earlier this year, Russia announced plans to send manned flights to the moon by 2030 after reviving its lunar programme with unmanned spacecraft.
It was the first time Moscow had set a deadline for the space plans, hoping to recapture the early glory of the first space race, when they beat the U.S. at getting a man to orbit the earth.

Barack Obama previously wanted to get Americans onto Mars by 2030. 

A Roscosmos spokesman said at the time: 'Close to 2030, the plan is to move over to manned flights to the Moon.'

The agency also announced that it would continue to work with Nasa on the ISS until 2024, when it hopes to build its own orbital station.

It says the station would aim to provide Russia 'with guaranteed access to the cosmos'.

Russian government officials had indicated last year that they may end funding of the ISS in 2020, amid strained relations between the the U.S and Russia over the Ukraine sanctions row. 

Extensive cooperation in space between Washington and Moscow came under renewed pressure after the U.S banned high-tech exports to Russia.

But that proposal appears to have been rejected in favour of keeping it going for another four years, as Nasa had suggested. 

The space industry has been the root of fierce competition between Russia and the U.S dating back to the Cold War.

The U.S and the Soviet Union were locked in the so-called 'space race' for decades.
Russia's Yuri Gagarin was the first man in space in 1961 and Neil Armstrong of the United States was the first man on the Moon in 1969.

But with the Cold War over, competition gave way to cooperation. 

Russia's subsequently deorbited its own Mir space station in 2001 as Moscow sought to concentrate its resources on the ISS.

Aviation Drone Strike

If our new great public technology of drones is generating so many almost air traffic collision problems, there should be some law that states drones to use TCAS sort of automatic collision avoiding system.

One more thing to worry beside bird strike. Now we will have Drone Strike.

Operational Systems War

Before thinking about write this article I was happy with my Win7 for it's user friendly desktop, my GNU/Linux Mint 13 for development, Android for my Sony smart-phone and Apple's IOs for my tablet (or IPad).

For stranger it may seem, the comfort of having so many different resources was given just and only for all options and tools one of those could give exclusively on that platform.

Windows 10 Wave
Not blaming Microsoft, in fact they did what should be done to keep the competition for the market - with is to force the users around the globe to use just their products and services like Apple or Google on it's own way.

With a fair price you can buy a Microsoft's Smart-Phone or Tablet and it's bleak the future between Microsoft and Sony products with is pointing for a new generation of laptops, computers and game consoles.

The Big Picture
Let's see some charts and facts to get a grip of what was going on in July 2015 regarding those systems:

* Chart based on NetApplications via Wikipedia.

What we can see in this chart above is that Microsoft dominate the OS market but with Windows 10 and the probable expansion of Microsoft own devices and computers is a prediction that Google is about to do the same path inverted and also, a response to Apple.

All this unification of services and products and the not so far future of new computers and devices lead us to know that there is a silent war going on and we are the ones who will decide between the easy way (giving away our identity and privacy) or the hard way using alternative systems like GNU/Linux and perhaps, save something private.

Corporations all over the world are giving two years before thinking about implementing the new Windows 10 and Sony itself is discouraging it's users to update till further instructions.

Wikipedia's Depression

There is a lot of great articles Wikipedia can offer in many languages and it is without a doubt the biggest on it's market.

Even with reports along the time of errors, span and even censure; it's huge content kept Wikipedia as a must-have favorite for millions.
Yesterday I went to Wikipedia to ask for an update of a mistaken part of an article and this was what I saw covering the entire top of the page:
 Followed by this:
As a non-profit organization is their legitimate right to ask people for donations of course, but like this, is almost saying: - Hey, pay us or our service will give you adds or worst. Just a PayPal's donate button isn't enough?

Wrong Way of Business
By doing this Wikipedia is showing the world users that it's not a free encyclopedia but a poor business planned organization that even being known worldwide can't raise funds from companies. Instead, they are trying to apply the in-app-purchase politics.

What is the Problem?
Wikipedia's survive and is feed by the worldwide community with gives information, moderation and more.
With this wrong business step, most users will stop to contribute freely since the organization itself showed instability over it's proposition of free on-line materials or even, how far the service will survive as it is.
