He is Apache N4SIR. Nearly a month after Microsoft shut down the original Xbox Live, he was one of the Noble 14 who kept their connections running. Their numbers slowly dwindled, and today, he was the last Spartan standing.

At 4 p.m. U.S. Pacific Time, Agent Windex and Apache N4SIR were the last ones left connected to Halo 2 multiplayer – a link kept alive since midnight of April 15. Though Microsoft attempted to lure the Halo 2 diehards away with Halo: Reach beta codes and a pat on the back they stayed in until they got the boot. But then at 4:21 Agent Windex sent this message to the Bungie forums:

I just got kicked off guys.

Good Job Apache, your the last one.

As of 7 p.m. U.S. PDT, Apache N4SIR was still in Halo 2 (see screen) – doing what, who knows. Apache N4SIR had been streaming his play, and now, without an opponent, wondered what he should be doing. Someone suggested beginning the campaign – but not beating the final mission, as it would sign him off.

Others asked that he capture himself signing out of the game and post the video to YouTube. I’m not sure what kind of signoff he could give to do this game justice. It should be something epic. Maybe something along these lines.

Final Update: Shortly before 11 p.m. PDT, May 10, 2010, Apache N4SIR left Halo 2. he says he was booted from the game. This is the end of multiplayer on Halo 2 and the original Xbox Live.

Genre: Video Training | 841 MB

Ruby on Rails aims to make building web applications simpler. in Ruby on Rails Essential Training, expert instructor Kevin Skoglund focuses on the same goal. Kevin explains the complete process—from understanding the fundamental concepts behind any Ruby on Rails project to creating full-featured, easy-to-maintain applications using the Ruby on Rails framework.

Using the practical project of building an online store as an example, Skoglund teaches the basics of the Ruby language. He also covers how to design an application, how to build dynamic interfaces, how to structure and interact with databases, how to create a working shopping cart, and how to regulate user access with passwords. Exercise files accompany the tutorials.

NOTE: Several key features of Rails have changed since the release of Ruby on Rails Essential Training in the lynda.com library. The following link details these changes: _www.nullislove.com.

Last week’s release of MeeGo v1 is an effort by US chip maker Intel and European cellular giant Nokia to enter the mobile OS arena. Will it be able to compete? While Apple and Google vie for market dominance, MeeGo offers itself as a 3rd choice with strong Linux roots.

Merged Linux Projects

MeeGo is a combination of Intel’s Moblin project and Nokia’s Maemo 5, both of which aimed to create friendly Linux-based mobile systems.

Maemo was created in 2005 as Nokia’s attempt at a modern smartphone OS. though its Symbian OS still holds about 50% of the global mobile OS share, begun nearly 30 years ago, the system is showing its age.

Maemo has so far proven popular with developers due to its Debian Linux roots. Because availabilty has been limited to only a handful of Nokia devices, though, it has so far not been allowed to grow outside its niche technical user group.

The Moblin project, which drew heavily from the Red Hat family of Linux, has already been adopted by a handful of device manufacturers, though has also remained relatively low-key.

As isolated projects both of these operating systems lost ground to Android and the iPhoneOS.

MeeGo hopes to spark interest with a largely pure Linux kernel at its core and a range of developers and manufacturers will be encouraged to create apps and a community around the OS much like a typical Linux distribution.

Android, Google’s freely usable and Linux-based smartphone OS, still contains restricted features and 3rd-party software that hold it back from being a fully open and interoperable platform. The iPhoneOS, has also much received criticism for being too tightly controlled by Apple.

Hardware and Software

Maemo made large strides in usability, but the Moblin project brings its optimization for Intel’s Atom low-energy processors to MeeGo.

Many manufacturers have already started incorporating the Atom chips into mobile devices, but both Asus and Nokia are expected to release a line of next-generation netbooks and Internet tablets paired with both Atom processors and the MeeGo OS.

Though MeeGo will be able to combine the best parts from both projects, this has already caused a rift in the community. former Maemo project and application developers are timid to fully embrace MeeGo, mainly because the newer system has chosen to use Moblin’s Red Hat-derived RPM package manager over the Maemo Debian apt-get software manager.

Apt-get application packages will still be installable in the RPM environment, but the fear is that the move will cause the large Debian-family development community to lose interest in the MeeGo project.

What Matters The Most

Though both containing a multitude of new apps, Apple’s and Google’s app stores leave something to be desired. Apple is at times too controlling, and Android’s app store has been called “the wild west”, where developers can expect regulations and compatibilities to change at any moment.

MeeGo’s focus on a wide range of devices will mean that users could be given a choice in sources for applications: netbook users will likely use Intel’s AppUp store while mobile phone MeeGo systems will use Nokia’s Ovi marketplace. Each of these marketplaces offer device-specialized applications.

Early-bird consumers should be cautious not to expect a large offering of applications for MeeGo just yet. While the system promises to be a stable developing environment, neither the Maemo nor the Moblin project had large app stores to begin with.

It is be possible translate vast amounts of native Linux applications to run on MeeGo, but this will take time.

Will it successfully maneuver to become a third choice, or will it end up content in 3rd place? only time will tell if MeeGo can mature responsively enough to compete globally as a leading mobile device operating system.

Large Ruby on Rails resouce for all levels w/ Articles, Tutorials & more

Forewordby Brett Thomas
If you’re anything like me (even before I got really involved with bit-tech.net), you’ve got spare parts everywhere. you know what I mean – systems that you have put aside as you’ve upgraded over the years, like Northwood P4s and Athlon XP boards that have gone the way of the dodo. They aren’t your top gaming rig – they don’t even need 200W to run, much less have 200W for the graphics card.

In my goal of helping you find new and useful ways to use that old crap, it dawned on me – everyone I know complains about files on this computer or that computer, or not being able to get the things they need or want while they’re out or away from their home desk. They needed a file server – a REAL file server, with web interface and bit-torrent and the capacity to not tie up your precious screens and keyboards, which are (at least in my house) in less supply than motherboards and hard drives.

It needs to be fast, extensible, flexible, run on old spare parts, and be completely headless after about two hours. It needs to be Linux. and apparently I need to be our resident Linux expert, Ken “Glider” Gypen…

IntroductionAfter showing that one of the known pitfalls of Linux isn’t as bad as most expected, it’s about time to get things into gear and show one of the strengths of Linux. It’s a known fact that Linux (or any other flavour of ‘Nix) is a great OS to run on that low power, the-day-before-yesterday’s-generation hardware. That’s because the strength of Linux lies in its Command Line Interface (CLI). While scary to those who are used to point and click, CLI offers a no-nonsense, straight to the point and low-overhead powerhouse.

Many accustomed to graphical interfaces find the CLI old and obsolete. but they just don’t grasp the strength of the interface. since most things in Linux are done through the manipulation of (small) files, there often is no need for some eye candy. With a relative small number of commands you can totally change the functioning of a Linux system. CLI isn’t hard to learn and Linux offers a great tool for learning it, the “man” pages.

But enough of the chatting, Brett asked me to write a guide on how to install a home file server, with a GUI (sigh). In addition to that, he wanted it to run headless, thus requiring a remote administration. also, a web-based P2P solution was offered to run on the box, so that you can shut down your power hungry workstation, and leave the downloading for the economic box. and to finish things up, I’ll briefly touch the area of scripting. Scripting is the edge that Linux has to offer over Windows – Mac users will know of it a bit if you are familiar with Automator. most tasks can be automated through scripts – a (lesser) known saying in the Linux world goes: “If you need to do something more than 3 times, you should write a script for it.”

But enough of the chatting, lets get this party started…

HardwareAs already touched in the introduction, Linux needs next to no hardware to run on. I know plenty of people who run a Linux gateway on a old 486. that is an impressive clock speed of 16MHz! Unfortunately we aren’t building a gateway right now. given the requirements of this article, we need something a lot more beefy. Certainly things like an X- and web-server require a fair bit more power. Certainly the X server.

That’s why I chose Xubuntu. Ubuntu is considered as one of the most newbiefriendly distributions out there, but it uses the heavier Gnome window managers, while Xubuntu uses XFCE. Minimum requirements for Gnome are a 500MHz CPU, opposed to the 133MHz needed for XFCE. However, since our box will be multi role, the minimum specification of 133MHz might be a little low. Don’t get me wrong, all will work, but not as smoothly. anything 750MHz or up will do just fine.

RAM wise, Xubuntu once again is the limiting factor. The install requires 192MB to complete. Afterwards, the system isn’t as RAM hungry, so 192MB should be plenty. In the area of disk space, we are building a file server so the more the better. The OS doesn’t require a lot, about 2.5GB. Disk space is considered to be cheap, so nothing problematic on this front either.

Basically, anything halfway decent from two years ago will do. Maybe you could use that hardware you had to throw out to run Vista? In case you have some lesser hardware lying around, don’t fear. By letting go of the GUI you can lower the requirements quite a bit. also, all Linux flavours are different, yet so similar. to get the requirements down you can just use the “Ubuntu Server” install. then you won’t get the GUI, but none the less all will function. if you want even more control, try another distribution, like Debian or Gentoo if you are feeling lucky.

Personally, I’ve ‘assembled’ a virtual PC, thanks to the guys over at VirtualBox. The system has 256MB of RAM and 10GB of disk space at its disposal. for those of you working on a real machine, here’s a tip – the first thing I do when I build a server is walk around in the BIOS. I then disable all unneeded things that I discover on my journey.

If it isn’t needed, turn it off. that way it can’t break.

Please accept the terms of service and privacy policy

If you need users the accept the terms of services and privcay policy or your rails application there is a simple way to handle this without a database field or javascript. It’s using the validation methods built into rails. Simply add the following code to your User model for example

validates_acceptance_of :terms_of_service

Then in your view add the following to your view and you will get a checkbox on the page that users will be required to check.

<%= check_box :user, :terms_of_service %>

This will then add this validation rule to your models validation rules and when you try to submit the form without checking the checkbox you get a nice little validation message letting you know hey you need to accept this.

Of course you can have your own validation message displayed like so

validates_acceptance_of :terms_of_service, :message => ‘ and the privacy policy must be accepted’
