Lion's eat RAM's

I recently purchased a Mac-mini(Yes I own a Mac now) with relatively the same hardware specs as my(well the one I work with) MacBook pro, Intel Core i5,Graphics 3000(or whatever) etc. The only difference being that the ram in the Mini was only 2GB and the Laptop has 4GB,we will come back to this later.

The MacBook Pro experience: My experience with the laptop has been great,never lagging and I really got used to using a track-pad instead of a mouse and found gestures very helpful for quick desktop management with a small screen.It was also very responsive and I keep tons of windows open all the time without problems.



 When I got my Mac Mini,I popped it out of its box and plugged it in to my standard PC peripherals,switched it on and everything worked fine ,I got a few nice surprises too,I did not expect it to come with a wireless card or built in Bluetooth,just like it does on the MacBook.

Then I tried to run Safari,iTunes and Xcode all at once(I do this often while working on the MacBook) and things where not so fine anymore ,the Dock was slow to respond and animate and everything was sticky.So I downloaded an app that shows memory usage in the finder bar,and Wow was I surprised,20MB free is the kind of thing you expect to see when running a hefty virtual machine,not 3 apps,it's crazy even for a 2 gig machine).

 Some research into the subject revealed that OSX Lion uses as much RAM as it can so that it has quick access to data for applications,making them more responsive,however I was getting the opposite on my Mini with 2GB of RAM,compared to the awesome performance of the 4GB in the MacBook,So to me it seemed that 2GB of RAM just wasn't enough for Lion.

I decided to obtain a 4GB chip to stick along side one of the 1GB chips already in the Mac-Mini and I proved myself right. From startup Lion gobbled up 2 of my RAMs(2GBs of RAM,I'm trying to be metaphorical) but proceeded to be smooth and quick,exactly what I'm used to on the MacBook Pro,after starting up a virtual machine and numerous other applications I noticed that nearly all of my 5GB of ram was gobbled up (I had 10MB free) but I didn't notice a performance drop like I did when I only had 2GB of ram. So whats the point of this story?


 Well the point is OSX Lion is great but if you intend running it,make sure your machine has at the very least 4GB of ram or your experience will be tarnished PS: I realize that I may have written this article badly,but its 12:45AM so that's my excuse.

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 …

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…
