Setting up Qt Creator for assembly


After fiddling with inline asssembly (not very successfully) ,I recently decided to try writing proper assembly and compiling with NASM in Linux. After writing a hello world using gedit and having a terminal open for compiling,linking and running I had a thought.,there has to be a better way to do this.

So I tried Qt Creator ,because I know it's easy to add custom build and run commands,and what do you know? I got it to work. Here's how,my screenshots and assembly code are in Linux but the set up should be the same regardless of the operating system,if you are not using Linux then just use the same commands you use to assemble in your operating system.

First off ,create a new console application:



I named mine ASM
Rename the main.cpp to main.asm and delete all the text inside.then insert some assembly:



Now open up the “Project” tab and edit the build settings,remove the current build and clean steps and remove the “-build-desktop” from the end of the build directory line.

Now add two custom build steps,these would be the two commands that you would usually use to compile assembly

“nasm -f elf main.asm” and “ld -s -o ASM main.o ” (“ld -m elf_i386 main.o -o ASM” if you are a x86_64 user)

Take note where I used “ASM” this is the name I gave the Qt project in the beginning.

Heres what it should look like,remember to check “Enable custom process step”



And thats it ,now when you hit the run button the assembly is built and run and you can see the output under “application output”.

Running Node.js alongside IIS on Windows

Most of the time when you are looking for a way to run Node.js as a production server on Windows you will just run into IISNode , now IISNode is a great thing ,but I'm a fan of choice and most importantly , not a fan of XML web config files.

I wanted to run my node server on what ever port I wished,or maybe even a different server and just have IIS reroute the traffic from a particular URL to the node process(so a proxy), this allows you to still manage your own load balancing and possibly scale up from that point without having to bother with IIS again.

So first things first you will want to download and install the URL Rewrite and ARR modules for IIS

ARR (Application Request Routing)URL Rewrite Once thats done lets crack open IIS and open up Application Request Routing, then navigate to Server Proxy Settings and Check Enable Proxy and Apply.







Now lets create an an application on our Default Website that will link our url to the node process, here im directing it to an empty direc…

Half-Life 2 for OSX , how well does it run?

Earlier this week Valve advertised Half-Life 2 for the Mac with the best advert I have ever seen. They took the old 1984 Mac advert and re-created it using the source engine and characters from the game. As if the awesome(albeit 35 second) entertainment wasn't enough they offered the game at $3.40 for a limited period. It was not shortly afterwards that I made my first ever purchase on Steam(its kind of strange buying a game and not getting a box with it).




The game purchase actually allows you to download the OSX or Windows version of the game , depending on the platform you are logged in to .This is great , because I have a PC with some decent gaming power and my Mac Mini (which I naturally wanted to test on) and wow ,the OSX version runs pretty darn well,especially considering that my mac mini is running only an intel HD3000.



Performance
I was surprised how well the game performed on high settings , the gameplay was smooth with the default high settings , reaching frame-rates up …

Controlling an LED on an Arduino over HTTP

Prerequisites
You will need node.js and npm installed , and should have at least some knowledge when it comes to node, if you do not , I suggest you try some example code in node before diving into controlling hardware with it. You must have the Arduino IDE installed on your machineYou must know how to get an LED working on pin 13 of an Arduino
Set up the Arduino
Wire up an LED to the Arduino on pin 13 and plug it into your development machine. Now we need to get it ready to talk to johnny-five. To do this simply follow the instructions under johnny-five's readme
Set up the project 

Create a folder on your development machine for the project , in this folder create the server.js and index.html files. Copy the code from the files in this gist to the respective files.

Loading ....
We aren't done yet , we need johnny-five and the narf for this to work. In your project directory run the following command:

npm install narf johnny-five

If that succeeded we now have the johnny-five libra…
