DIY Desktop Virtual Reality Display on the cheap (Nintendo WII Only)

Saturday, January 26th, 2008

Johnny Lee, and his WIImote hacking tips has created a way to make 3D games (for the WII) a reality using DIY IR glasses. This is a really cool concept, the software tracks the movement of your head and adjusts the current display accordingly. I am definitely going to experiment with this technology.

Call for help! Ruby - On - Rails Shipping Gem

Wednesday, October 17th, 2007

Hello everyone, I have been programming in Ruby using the Rails framework for a while now. However I have a situation where I am developing a shipping calculator for my applications using the Ruby “shipping gem”. The problem, at least I think, is the account number, username, password or all of the aforementioned attributes are incorrect. I have verified they are indeed correct and valid. I am getting an object returned to me in my code called the Shipping::ShippingError object. I am sure there is some kind of a message stored inside this object but I cannot access it because I think it is actually a Class. In short what I need to know is how do I, if at all extract the error from this Class? Object? so I can display it to the screen. Below is a code example.

The configuration file “shipping.yml”

#../../config/shipping.yml
ups_account: XXXXX
ups_user: XXXXX
ups_password: XXXXX

The Shipping Controller “app/controllers/shipping_controller.rb”

#app/controllers/shipping_controller.rb
class ShippingController < ApplicationController
   def quote
      params = {
                     :zip => 54494,
                     :state => “Wisconsin”,
                     :weight => 1,
                     :sender_zip => 68801,
                     :sender_state = “Nebraska”,
                     :prefs => “#{RAILS_ROOT}/config/shipping.yml” }

      @shipping = Shipping::UPS.new params
      @errors = Shipping::ShippingError
      #in the view we will show price like so @shipping.price
   end
end

The view file “shipping/quote.rhtml”

Test Shipping
This is a test of the UPS shipping code.
Output = [<%= @shipping.price %>]

Preventing Bad Grease Monkeys from changing your prices in eCommerce sites

Thursday, April 12th, 2007

Naughty Grease MonkiesI spoke with Gina Trapani on Wednesday about my concerns on this issue. The problem is that many online shops are using hidden fields in forms to pass information such as pricing, shipping, and quantity to their online checkout systems. Now I love Google Checkout for its sheer simple integration methods, but there is also an option to auto approve the payment and this concerns me. So I am writing to you today to illustrate some of the methods I have came up with which will hopefully prevent this sort of attack. Here are three ways you can circumvent this little flaw in many online stores.

Video wallpaper on any version of Vista or XP with VLC Player

Wednesday, April 11th, 2007

A lot of people are switching to Vista for it’s great features. One of the great features is DreamScene which allows you to play high-definition video as your desktop wallpaper. I am stuck with XP for the time being and won’t be switching to Vista anytime soon. So I began looking around on the internet for an alternative to using videos as wallpaper. I found a quick tutorial on Digg on how to do just that. The best part about this little trick is that it will work on Windows XP, Windows Vista Home, Windows Vista Home Premium, Windows Vista Business Edition and maybe even a few other operating systems. Now I could link to the article and probably should, but that would just cause you to have to reload your browser and it’s really quite simple. So what I am going to do is try to illustrate the basic concept of this trick and also link to the article because there is a more in depth explaination of how to get this up and running. I have mentioned VLC Player in the past and many of it’s great features, but if you haven’t already downloaded your free copy the url is http://www.videolan.org/vlc/. Now to do this all you need to do is install VLC Player, open a video file, and right click and check “wallpaper” and thats it. You now have a beautiful animated background using video from your most recent vacation trip, or maybe your favorite movie. It’s that simple.

Bonus Tip:
More than likely you will not want your video to play just once when you are using it for this purpose. So you will need to tell VLC to loop the video in the playlist interface found under navigation in the toolbar menu. Also you may wish to disable the sound so it doesn’t drive you crazy after playing 99 times over and over. To do this goto audio and select disable. Thats it, you now have the great feature of DreameScene on your non-DreamScene compatible operating system.

Favorite picks for Open Source Applications

Tuesday, April 10th, 2007

It’s no secret I love Open Source applications. Why? Well it’s really quite simple. When an application is Open Source you have much more control over how the application behaves and can easily customize it to your liking. Software that is not Open Source is similar to leasing a vehicle sure you own it, but you don’t have the right to fully pimp your ride. Below I have listed some of my favorite open source apps. Some are more promising than others and I am sure I have not covered all of the great open source apps out there. So to be fair if I missed any good ones please let me know in the comments.

  1. Firefox - Open source web browser with tons of great features, extensions, themes and more.
  2. Democracy Player - Open source media player that allows you to download torrents and play them in the same application. Democracy also supports a number of other great media formats.
  3. RSSOwl - A great little RSS reader.
  4. VLC - Handy video player that supports most video formats including Quicktime, AVI, DIVX, OGG, MPEG, VCD and etc.
  5. Audacity - Free audio editor packed with features. Enables copy and paste, audio filters and more.
  6. Notepad ++ Free full featured text editor. This one is great it supports syntax highlighting for 30 or so programming languages for all you programmers out there. Also see Scite (Ships with ROR) and Programmers Notepad.
  7. 7-Zip - Great little file archive tool that can open just about any archive file you through at it. Think of it as the swiss army knife of file archive utilities.
  8. Greasemonkey - Firefox Extension that allows you to execute your own Javascript files based on url locations. There are a lot of great Greasemonkey scripts already built that make this tool a must have for Firefox users.

Going with the flow via Google TiSP beta?

Google TiSP

I couldn’t believe my eyes this morning when I went to Google and seen a link stating “New! Get FREE breakthrough broadband with Google TiSP (BETA)” So I followed the link and found it to be a system for FREE wi-fi via the toilet. This is obviously somone’s joke but is it Google’s? I strongly doubt this is a real page made by Google. I am not sure whether their homepage was defaced or if this is just some sort of prank from our friends at Google. Regardless I took some screenshots as this page may not be up for long. See the screenshots below.

DIY Tips for a Spam-Free Inbox

Saturday, January 27th, 2007

DIY Tips for a Spam-Free InboxWhether we like it or not, spam is a part of our digital lives. Personally I hate spam in my inbox. Guy Roberts, anti-spam research manager, McAfee, Inc. has some tips to help you avoid getting more spam with his DIY Tips for a Spam-Free Inbox. Some of the tips include …

  1. Never respond to spam. If you reply, even to request removing your e-mail address from the mailing list, you are confirming that your e-mail address is valid and that the spam has been successfully delivered to your inbox. Lists of confirmed e-mail addresses are more valuable to spammers than unconfirmed lists, and are frequently bought and sold by spammers.
  2. When filling out Web forms, check the site’s privacy policy to ensure it will not be sold or passed on to other companies. There may be a checkbox to opt out of third party mailings.

Security Tip: Better passwords with a CueCat (Windows)

Thursday, January 25th, 2007

Cuecat

CueCats are barcode scanners that were given away by Digital Convergence in the late 1990s. They were designed as a way for consumers to scan barcodes from magazines and other media and be directed to a website with more information on the product or service they scanned. The scans were encrypted to prevent law suits based on the DMCA (Digital Millennium Copyright Act) of 1998. However they are still useful today as a low cost barcode scanning solution with a little hardware modification and or some free software known as CatNip which bypasses the encryption. The nice thing about these devices is that they type any scan into any field and press enter which makes them perfect for passwords. In this article I am going to show you how to take your modified or unmodified CueCat and use it to login to your computer via passwords encoded into barcode format.

What you will need.

1. A CueCat USB or PS2 will work.
2. A barcode (You can use one from an existing rewards card or make your own here)
3. An account to test it on before using this as your form of authentication.

Google AdSense banning users from participation

Wednesday, January 17th, 2007

Google AdSense logo

Google AdSense banned me from participation in their program last summer. The resons to me are not clear but there seems to be a number of other people in the same boat. Appearntly I was banned for “fraudulent clicks” which translates into the same IP or computer system clicking on ads published by an AdSense account.

If you create an AdSense account at a public WiFi spot or a public network and someone else accesses your ads from the same network then you may appear to be generating “fradulent clicks” to Google and it wont be long until they ban you even if you did not intentionally click your ad’s. So what can someone do once they are banned from use of Google AdSense. Well according to Google they will not reinstate any previously banned accounts. Well I am banned and I plan to try and get unbanned from the program. I will be posting about it here to keep anyone interested up to date on my progress.

Google Inc.
1600 Amphitheatre Parkway

I plan to call them this week and see what I can find out. If any of my readers have encountered this problem and have any insight on how to correct this issue please feel free to send it to tips@timmatheson.com

HowTo Tell if a DVD or CD disc is blank

Monday, January 15th, 2007

I made a quick video to demonstrate how you can tell if a CD or DVD is blank. If you look on a disc that is not blank you will notice a ring indicating the disc’s contents. The further the ring is to the “outer” edge the more data the disc contains. Pretty simple but useful.
