BevMax softdrink vending machine DOES NOT WORK


This is the Bevmax softdrink vending machine. As you can see, it differs from other vending machines in that it has a clear front, allowing you to see the tasty beverages inside. Supposedly, the Bevmax machine increases vending machine sales over the regular, opaque vending machines.

On the surface, it looks like a normal, albeit clear, vending machine. It has a keypad, coin and bill insert slots, and a small readout. HOWEVER, the Bevmax softdrink vending machine has one GLARING design flaw.

There is one of these vending machines in Main Hall near the C3 store and another in the break room in Recitation . The problem with these vending machines is that they are VERY likely to jam. The Plexiglas that shows you the tasty beverages is too close to the racks where the items are stored. When the product is vended, it pops out of its slot, hits the glass, and, if it doesn't fall in a perfectly straight line down, the base hits another rack and gets stuck, wedging the top and bottom of the beverage between the rack and the glass. This makes it almost impossible to shake loose, leaving you out of luck for a $1.50 beverage or more. I have seen this particular type of vending machine jam more times then every other type of machine COMBINED.

To fix this, one of two things needs to happen. Either the glass needs to be moved farther away from the racks to prevent wedging, or a Surevend system needs to be implemented in order to assure you get your beverage, or at least your money back.

Until then, stay away from these machines.

The Glock 26 works for Caboose

As an American citizen and a believer in the Constitution, I also believe in the right of the people to keep and bear arms. In keeping with this belief, I recently purchased a Glock 26 9mm pistol from a local firearms dealer. This was the first pistol I have ever purchased, so I decided to critique its usability.

The Glock 26, pictured here, measures 6.29 in. long and 4.17 in. high and weighs roughly 26 oz. when the firearms is loaded with the standard 10 9mm rounds. This seems very small, especially for a rather large person like myself, but the Glock 26 feels like it was molded specifically for me. My middle and ring fingers fit into the groves of the grip, my index finger can rest comfortably along the triggerguard or on the trigger, my pinkie curls comfortably under the magazine well, and my thumb can easily manipulate both the slide and magazine release buttons, as pictured below.
Once I had taken my Glock to the range and gotten it broken in, everything is very easy to manipulate. The slide release button, located just above my thumb in the middle of the weapon in the picture above. Releases a locked slide with a light press down. The only problem is it is a bit small, which means people with large or sweaty fingers might slip off before it is depressed. The magzine release button, located just below my thumb in the picture, is firm, without being stiff. Its placement makes it hard to accidentally press with the fingers from below due to the trigger guard. The pressure required for magazine release is also enough that it is hard to accidentally eject the magazine with a brush of the thumb.

The trigger of the pistol requires a rather long pull to fire, 5.5lbs of pressure and half an inch of pull, but this only serves to prevent negligent discharges. You have to want to pull the trigger in order for it to move.

As with all Glocks, the Glock 26 has three safeties. A dropped gun safety that prevents the firing pin from moving forward if the weapon is accidentally dropped. A firing pin safety that prevents the firing pin from striking a chambered round without a trigger pull if the pin does move, and a trigger safety, that prevents the trigger from moving unless it is depressed while firing.

While there is no external lever safety, unlike many other firearms, the three of these mean you must want the weapon to fire in order for it to fire. Despite this, however, proper firearm handling should be followed at all times to prevent accidental injury to you or others.

Disassembly of the Glock pistol is very easy. The takedown lever is located just above the triggerguard, and to separate the slide from the frame, only a few simple steps must be followed.

First, the firearm must be completely unloaded. Then the trigger must be pulled so the firing pin is decocked. Once that is done, the slide must be pulled about 1/8th of an inch backwards, easily accomplished with the grip shown in the picture to the right. The takedown lever is then pulled down with the other hand, and the slide can then be slid off. Once that is accomplished, the recoil spring and barrel can be separated with the fingers. That is all the disassembly the Glock needs for cleaning and basic maintenance.

In conclusion, the Glock 26 is a very user friendly firearm, with a great positioning of components, the right balance between safetey and ease of use, and a great combination of concealability, capacity, and firepower.

The Evolution of the Xbox controller

In 2001 Microsoft released their first attempt at console gaming with the mantra "Bigger is better". The original Xbox was a massive black behemoth with an equally huge controller. As was the norm for Microsoft at the time, they released a product with very little usability testing, and then tried to improve upon it. Thankfully, with the release of the Xbox 360, this kind of thinking changed to fit with the console's name, and the company changed the design of their controller for the better.



The first Xbox controller, pictured above, was a nightmare in terms of usability. The Duke, as it became to be called, is bigger than any other hand held controller commercially available. Now, I am a big boy, but the size of this controller was just unnecessary cumbersome, especially to those who had been used to the Playstation's controller. Much of the controller is taken up by the Xbox logo in the middle of the device, which leads me to believe the large size was chosen in order to generate talk about the console.

The controller fits into the hands of an adult reasonably well, but small children, many of whom received Xboxes for Christmas, have trouble using it at all. For an adult, the two analog sticks are in good places; the left in the high position, and the right in the lower position. This allows both sticks to be manipulated with the thumbs in opposite directions without bumping into each other, which could occur on Sony's original Dual Shock controllers. However, the right analog stick is to rounded, which means a player's thumb can slip off during heated, and sweaty, sessions.

The buttons on the controller are another matter, and are the chief complaint about the Duke. Starting on the left, below the analog stick, is the directional pad (D-pad). The D-pad is in the same lower position as the right analog stick and can be manipulated easily with the left thumb. It is oddly shaped with an inverted and rounded design, the directions are sunken into the pad instead of raised above it, but this did not cause many problems.

However, the right buttons, which are used much more frequently, are not designed well. They are small, rounded, and slick, and, while the XYAB buttons are reachable, the black and white buttons are almost untouchable. Finger slips causing erroneous button pushes were a frequent problem, but the black and white buttons are the prime example of why is controller has very poor usability. It is all but impossible to press the buttons without removing your hand from the controller, which is a death sentence in the fast paced world of video games.

The trigger buttons, which are located on the underside of the controller, are great. They are easily manipulated by the index fingers and are in a comfortable position.

While the Duke controller scores poor in usability, it did have one innovative feature that probably saved thousands of dollars worth of damaged Xboxes. The cord for the controller has two parts, the connector that plugs into the console, and the length of the cord. These two parts are joined by break away connector that, when jerked quickly, separates with no damage and can be reconnected easily. This means that, if someone trips over a cord, the console is not pulled forward and should not fall from a shelf or table. This prevents possible damage to the console, saving the customer money.


Shortly within a year of the Xbox's release, Microsoft switched from the Duke to the Controller S, which was originally only available in Japan. Pictured here with the Duke, the controller S is an attempt to address all of the Duke's usability problems, and it largely succeeds.



Obviously, the controller is smaller than the Duke, and fits into smaller hands more easily. The analog sticks are comfortable and have a depression big enough for your thumb to rest in without slipping. The XYAB buttons are larger and spaced farther apart, meaning erroneous button pushes are much harder to accidentally do. The D-pad was changed to the classic raised design, making it much easier to make diagonal presses. However, Microsoft's endeavor to keep the black and white buttons still causes a problem for the controller. While they are able to be pressed now, their position means that the thumb must be cocked at an uncomfortable angle, or they must be pressed with the length of the finger, instead of the tip.

One particular scenario which I experienced illustrates the problems that can be caused by this setup perfectly. In the Rockstar game Grand Theft Auto: San Andreas, when trying to preform a drive-by shooting, the player must press the right trigger to control the car's acceleration, the left analog stick to steer, the white button to look left, the left trigger to fire, and the X button to brake. It took me a long time to even adequately master this control scheme, and I often resorted to just running enemies over instead of trying to shoot them.


The evolution of the Xbox controller occurred with the release of the Xbox 360 in 2005. Microsoft extensively tested their new product, and the result was what might be the perfect videogame controller. When held in the hands, the player's index fingers naturally rest over the triggers, the left thumb on the left analog stick, and the right thumb on the XYAB buttons, as pictured here. The D-pad and right analog stick can be easily and comfortably manipulated with minimal thumb movement, and the improvements to the D-pad and analog sticks found in the Controller S are kept for the 360 model. However, the best increase in the usability of the 360 controller was the replacement of the black and white buttons with shoulder bumpers above the triggers. This allows the buttons to be pressed with just a quick flick of the index fingers, and, if necessary, the middle finger can be comfortably used to manipulate the triggers if both buttons must be pressed in tandem.

In my opinion, the 360 controller is the best controller manufactured to date, and if Microsoft produced all their products with as much usability as it has, Apple would have never had the resurgence that it did.

Domino's Pizza Online Ordering Works!

As a college student, I like pizza. A lot. More then I should in fact, and therefore I order it more then I should. When I started my academic career at West Chester University, the first thing I did was look for a pizza place. What I found was a local Domino's franchise. In my experience, this Domino's has been the best national pizza chain location I have dealt with in terms of quality, consistency, and courtesy. Their food is good, consistent, and their employees are courteous and helpful.

One time when I called Domino's I listened to their recording detailing their specials, and I heard they now have online ordering. I checked it out and got hooked - now I only order online. Recently, however, Domino's did an overhaul on their online ordering system and now it is even better then before!

You start by making an account. To make an account, all you need is an address, phone number, and Email account. The phone number is so the store can confirm that this is an actual person and not a bot, and to call if there is any questions about your order. The address is the default delivery address, and the email is for order confirmations. Once you make an account, the site will suggest local store locations for you to choose from. Once you have selected a store, you can begin your order.



Once you've registered, you can start to order.

The Getting Started Screen allows you to choose whether you want to make a pizza, order a specialty pizza, order a sandwich, order sides, or use or select a coupon.

Each selection is very user friendly, and today we're going to follow a typical order of mine.




So we click on "Browse all Coupons" and we are brought to this screen.


There are usually around a dozen coupons to choose from, ranging from single person deals to enough to feed a party. Clicking on the tabs at the top lets you browse by the number of people, or you can just scroll down.

I'm going to select the 1 Large American Legends Pizza, an 8 piece bread, and a 1 liter for $18.99




Once selected, it adds the coupon to the sidebar and brings you to a screen where you can make your pizza.


Since I chose an American Legend's pizza, there are already toppings on it, but if you had chosen a regular pizza, it would just be cheese. Here you choose the type of crust you want (I'm going to choose Classic Hand-tossed) and the size (Large, since that's the coupon).

Once selected, it brings you to the topping screen.



Here I have selected the Ultimate Pepperoni Feast pizza. If this were a regular pizza, you could select the topping you want by checking the boxes to the right. If you look closely, you can see pepperoni is checked and the extra tab is chosen.

Because I have a coupon, the site automatically takes me to the next item on the coupon, but if this were a regular order, you would be taken to a page that listen all available sides to choose from. IE: Wings, breads, salads, and soda.

Here I can choose which bread I want, regular bread sticks, or cheesey bread. I'm going to get cheesey bread.



The bread is not added to the sidebar, and I have the option to remove it if I change my mind, or change sauce if I wanted to. I also now choose my beverage, which will be Coke.




Now that that is done, I'm still at the sides page, but that is just for if I wanted to add more items to my order, however, I am done, so I click "Price order" on the right under the list of my items and am given the total of my order, which is $21.98.



Once I'm sure of my order I hit "Checkout" and am brought to the final screen. This being a commercial company, they try and get me to add another item, but I refuse and just click on continue.

Here I review my order, and select payment method. You can pay by cash, credit, or with gift cards. I select my method, then scroll down and hit "Place Order" at the bottom.



After my order is processed, an Email is sent to my account confirming the order, and I am brought to this screen.






This is Domino's pizza tracker. It tries to show you the process and time it takes for your pizza to be made and deliver. It's a neat system, but only an estimate. I've had pizzas get here after it's said it was delivered. The average time it takes for a pizza to get to me is about 45 minutes. Though I've seen as short as 30 and as long as 1 and 1/2 hours, it just depends on the business of the store.

So there you go, I hope I've convinced you to try Domino's online ordering. Just be aware, your experience may very, I have a very well run franchise here.
