Pandora’s large database of music and customizable personal stations makes

it a site that any music lover will find useful and engaging – and it’s free!

Pandora.com

Pandora Internet Radio is a digital radio station that allows users to create multiple, personally customized stations that plays only the music that relates to the individual’s own taste, selections and preferences. Users have the option of setting up a free account or purchasing an account (with additional features) for $36 per year. Registering is as simple as entering your email address and selecting a password (and NO, you don’t get any annoying emails!) and creating a station is as simple as selecting a song or artist. Other features of the site include setting up a personal profile, sharing music stations with friends, customizing your stations, meeting people with similar tastes, purchasing the songs that come up in your queue, as well as learning more about the musicians and music that you are listening to.

The Music Genome Project: History & About

The Music Genome Project (MGP) is the fuel that makes the Pandora system run so smoothly, allowing for the efficient and effective personalized musical experience. Born in the year 2000, the MGP is a comprehensive database of artists, songs and albums ranging from the ‘top artist’ of this past week to the Classical and Renaissance composers dating back to the 15th century. Since starting the MGP, Pandora’s 50 staff analysts, comprised primarily of music-loving individuals with 4-year degrees in music theory, composition or performance, have listened to hundreds of thousands of songs to prescribe certain musical attributes (over 400 in the database) to each song. These attributes pertain to the musical identity of the song and highlight specific features that help define it – harmonies, instrumentation, rhythm, vocals, influence, style, genre, etc.

When a user creates a station (more on this to come), let’s say with a ‘seed’ of Burning Spear, the MGP will then play only music on that station that the analysts have determined share similar attributes that are prevalent in Burning Spear’s music. For example, the Bob Marley song Sun is Shining might come up because it “features a reggae feel, heavy melodic ornamentation, a busy horn section, extensive vamping and mixed acoustic and electric ornamentation” – all attributes that are common amongst Burning Spear songs. More About MGP


Creating & Customizing Stations

Creating a station is extremely easy, but exacting your individual customization can take a little bit of trial and error experimentation. Building a station is as easy as selecting a song or artist as the ‘seed’ for your station after clicking the “Create New Station” button (located top left of your main action menu, see below Figure 1) – this triggers the MGP to start finding songs and artists that share similar attributes to your seed selection (as discussed above in the Burning Spear – Bob Marley example). Pandora allows you to build up to 100 stations, which is more than enough, and offers a few different ways to help customize each of them. Let’s take a look at a few of them below in the screenshot of your main action menu. Currently I’m listening to “Burning Spear Radio” as indicated by it being highlighted in orange (Figure 1 left side, Figure 2 condensed view). Here are a few things to pay attention to (see Table 1 below):

Allows you to edit station (delete ‘variety seeds’), rename station, share station or delete the station

Use the edit station function to trim away seeds that you don’t feel fit the station anymore. Use the share station function to give a station to others or find others who have similar tastes.

QuickMix

Figure 2, beneath station listings

Allows you select several of your stations and mix them without altering individual station

I suggest using this feature to add variety to your listening experience. Focus on developing each station individually by using the ‘add variety’ tool, then get good variety on the whole by creating a Quickmix of two or more stations.

Thumbs Down

Figure 3, beneath artist image on left

Tells MGP not to play this song or related songs in this station

Again, be very selective. Don’t simply say you don’t like a song just because you don’t want to hear it – once you give it a thumbs down, your station will alter itself permanently.

Thumbs Up

Figure 3, beneath artist image on left

Tells MGP to play this song and similar songs more often in this station

Reserve the use of this function for songs that you feel define the ‘feel’ that you think this station represents. The MGP will play this song more often and more related songs as well.

‘Menu’ Options

Figure 3, beneath artist image in center

Three station-altering functions:

(1) “I don’t like this song”

(2) “Why was this song selected?”

(3) “Move song to another station

(1) Tells MGP not to play this song on this station for one month

(2) Very helpful in learning how to build a station: tells you what musical attributes of this song made the MGP play it in this station. Study this to learn how MGP works.

(3) Allows you to move this song to one of your stations that you feel it fits better with.


Pandora Community

Pandora allows you to create a personal profile, share stations with other users, find other users with similar music tastes or search for users based on artist or song selections, and participate in a constantly updating blog. This is a valuable feature to the site if you plan on spending a lot of time on here and are curious about new music or the musical preferences of one your friends. I have found that the majority of people tend to ‘stretch out’ their stations too much by adding too many ‘variety seeds’ that don’t match up with the current seed structure of a given station. It can be fun however to learn what other people are listening to, and to find people who might share a similar taste in music. In my opinion, this feature is reserved for those seeking to truly find new music.


Pandora vs. XM/Serius Radio

Although Serius/XM Radio can be a great way for fans to find particular stations that meet their own individual tastes, Pandora Internet Radio is the next and more refined version of that. Serius Radio boasts over 69 music channels on their website, ranging from country, reggae and jazz, to jamband, classical and rock. With Pandora however, you have the ability to focus in on one certain part of a genre (rather than having to listen to a lot of music that you may not be interested in. For example, Burning Spear and Bob Marley would be under the reggae subgenre, “roots reggae,” a very different side of reggae than “ska,” “island” or “dub-step,” all of which would be incorporated into Serius’ one, all encompassing reggae channel – Pandora is the personally filtered version of Serius Radio.


The Downsides

Pandora offers a lot to its users, but there are certain limitations to the site that might disappoint a few of you out there. First of all, due to their licensing agreement, Pandora doesn’t allow you to select a specific song to hear at a given time – it will play only songs that are related to your station seed. Second, although only one ad pops up every seven songs or when you change stations and only lasts 15 seconds, some people might be annoyed. Sign-up for the $36 a year account if you love Pandora but just can’t handle the ads. Third, you can only skip six songs a day, again due to licensing agreements, but you can always switch stations if you don’t want to use one of your skips up. Also, as discussed above, it can be difficult to build a ‘successful station,’ but in my opinion that’s one of the more fun parts of the site – learning how it works by learning more about the music.

Grooveshark.com


The availability of music on the Web has completely changed the way we share, explore, and purchase it. Many file-sharing sites have emerged that allow users to illegally download music. However, a new site called Grooveshark.com emerged in 2006 and is attempting to create a legitimate online music streaming-site. Sam Tarantino, Founder and CEO of Grooveshark.com, began developing the site to improve the legal accessibility of music and to engage users in what some would call a “social networking site for music.” In a YouTube interview, Tarantino explains the basic functionality, objectives, and future goals of Grooveshark.


Purpose

Grooveshark is an online music database that enables users to purchase, download, share, and listen to music—relying on users themselves to upload and share their own music, much like Wikipedia relies on its users to add and edit information. Grooveshark VIP offers a membership for $3 a month, which removes advertisements and has other bonus features.


Getting Started

Creating an account is free and easy. Go directly to Grooveshark.com and click “Sign Up.” Then follow the directions by providing first and last name, user name, password, and email address. After logging in, the initial homepage offers some simple icons to get users started (see above).


User-Friendly Features

Clicking autoplay automatically recommends songs that are similar to your initial selection upon entering the site. Users can click on the album work of a song to rate it: a sad face to reject the song, a smiley face to keep it, or a heart icon to add the songs to favorites. After stopping autoplay, users can save that queue sequence as a playlist.

The queue (é) is a feature that stores songs in the order they were added and plays them in sequence. Users can also click and drag a playlist into the queue to listen to music non-stop.


Much like an online iPod, users can also customize their own widget and post it on any external website that provides permission. By clicking the middle “embed” button (é) located to the right of the queue, users can transfer songs and playlists to their widget.

Social networking capabilities enable one to connect with other users by searching for others that are Similar to Me, People Who Love Me and People I Love. All users can share music and playlists with each other via Grooveshark, Twitter, Facebook, StumbleUpon, and email.

Grooveshark offers a “Peer-to-Peer” (P2P) payment plan. If a user decides to pay for a song and download it, the price is divided and distributed so that profits not only go to the record label and Grooveshark, but also to the user. On a blog review of Grooveshark, Chris Morrison explains, “Of the 99 cent charge, 70 cents goes to the record label, 25 cents to me as a credit toward future music purchases, and the remaining 4 cents to Grooveshark” (Morrison).


Trouble Shooting

Although Grooveshark has begun tapping into the idea of legal music sharing, the interface design of the site itself is confusing:

1. Numerous clicks are required to access songs, artists, and playlists. As shown on the right, there are several pages of options that appear before the desired media becomes available.

2. Searching songs can produce an immense amount of related and semi-related results. Furthermore, some have different spellings and capitalization characters depending on how different users upload each song.

3. It is difficult to figure out how to delete playlists and songs from playlists.

4. There is no way to fast-forward through songs using a free account.

5. The autoplay feature recommended many songs that I had no interest in and the queue feature took a considerable amount of effort to figure out.

6. While using autoplay, I did encounter several bad quality files.


The Red Flag

Although Grooveshark offers users a legal way to listen to music, there is concern over the site turning illegal music into profit. Since it does not monitor uploaded content, files that were downloaded illegally from one source can then be uploaded as legitimate files and turned over for revenue on Grooveshark.


The Competition

Pandora is an online music recommendation site that allows users to create their own music stations and listen to others’ stations as well. After a particular song is entered, the site recommends similar music; however, it does not offer on-demand artists. Pandora, unlike Grooveshark, limits the amount of free listening to 40 hours per month and also limits the amount of times a user can skip a song to 12 every 24 hours. However, Pandora is accessible via smart phones.

Imeem is another popular site that links users together through “meems,” or groups of users that have similar interests. There are various types of media available: video, music, photos, and blog posts. The site also has a rating and flagging system for the media that is uploaded to keep low quality files at a minimum.


The Nitty Gritty

Despite the shortcomings of Grooveshark, it does offer a “no strings attached” experience to account holders—free, on-demand music. Although there is controversy over its legitimacy, the site remains available.

Scale: 1-5

Rating: 4

Nikon D300 DSLR Camera

A review by Cheri Falkner

Introduction
As technology continues to ease the entry into to digital photography, more and more consumers are entering into the world of digital SLR (single lens reflex) cameras. The camera manufacturers have found it necessary to change the way they think about the average consumer.

In July of 2009, Nikon introduced their latest model of DSLR camera into the market: the Nikon D3000. At a suggested retail price of $599 US, this camera delivers an great entry-level option for the beginner at a reasonable price point.

Features

While the D3000 may not offer as many features as the Nikon D5000 (such as video or live view), it offers plenty of features that are perfect for the beginner.

The D3000 offers:
  • A large 3.0 inch LCD screen
  • 11 auto-focus points allowing for auto-focus capabilities regardless of the image composition
  • 6 automatic modes that control settings specific to a certain composition. These include: landscape, portrait, child, sports, close up and night portrait
  • P, S, A and M modes to allow the user more creative control over the image results
  • A Guide mode that allows the user to capture an image and improve it using the on-screen guide suggestions
  • A burst mode of three frames per second capturing a series of high speed events
  • ISO sensitivity range of 100 to 1600

As Easy as 1, 2, 3…
When photographers are approached regarding a particular brand of camera one should buy, most will say that it is a matter of personal preference. Some will say that Canon cameras are easier to use – especially for the novice. The Nikon D3000 breaks that barrier by providing a user interface that is easy to understand and easy to use. The graphical representation of the aperture is especially helpful. In photography, as the f-stop number increases, the amount of light that hits the sensor decreases. This inverse relationship can be very confusing to the beginner, but this camera shows the user in graphical form the relationship of the f-stop to the amount of light allowed. As the f-stop is changed, so does the graphical interface.

A Picture is Worth a Thousand Words
One might think that the image quality on an entry-level DSLR may be compromised given the lower price point. That is not the case with the Nikon D3000. This camera provides excellent detail quality in the images produced. An example is shown below.

This image was taken in Close Up mode from approximately six inches from the subject. The camera picked up the small details of the cat such as the whiskers and individual strands of fur. The D3000 accurately captured the incandescent lighting in the room giving the subject a warm cast.


Figure 2: Sample photo taken in Close Up mode

Out of the Box Thinking
Another positive thing that Nikon did with this model is how they chose to group the product. With most DSLR cameras, one must purchase the camera body and the lens separately. The D3000 comes prepackaged with almost everything a beginner needs to start shoot as soon as they open the box.

In addition to the camera body, the camera comes with a 18-55 auto focus lens and a rechargeable LI-ion battery with a quick charger. Other accessories are included in the box such as a camera strap, eyepiece cap, software CD-ROM, a quick start guide and a reference manual CD-ROM. A printed reference manual that can be tucked in the camera bag was not included.


What Should I Do?
If you are in the market for a new camera and have been considering moving from your point-and-shoot camera to a DSLR, this camera should definitely be on your list of those to consider. Granted, it’s missing the live view and video offered by the Nikon D5000, but it is also less expensive. With the money saved, you could purchase a lens that could be used with future Nikon brand cameras you purchase in the future when you decide you are ready for an upgrade due to further advancements in digital photography technology.

Overall, this camera is top notch. While there are a few additional features that could be included, this is a great camera for the beginner. For that reason, the Nikon D3000 receives a ranking of 4 out of 5. Some additional features and a printed manual would have raised the ranking to a 5.

Nikon is definitely headed in the right direction with the release of this camera.

MacBook Pro vs. HP 6230 Series PC Notebook Computer Review












When getting a laptop for college, there are a number of things to consider, usually price is a huge factor, but quality and overall comfort is also a big concern. Carful consideration should also be given to the two major types: PCs or Apple.

As a student at the University of Wisconsin-Stout, I have had the opportunity to work with both of laptop computers, the Hewlett Packard (HP) 6230 Series PC and the Apple MacBook Pro. I will briefly review aspects of both laptops that I found to be important to me a as a student. Since each computer was pre-loaded with software suites required by the university, I won’t be discussing software applications. However, regardless of the brand of computer, certain requirements as a student and laptop user were more important to me than others.

Features

I have found that some features were more important to me as a student than others, most people immediately think about the memory and processor, but don’t give much thought to the “details” that make the computer more personal. Included in this review are the features I think are important considerations.

Screen

The HP series laptop has a 14-inch XGA matte screen, while the MacBook Pro features a 15.4 inch glossy LED-backlit display. Although both displays are adequate, I prefer the HP’s screen because of its matte finish, which provides the user with a clearer screen picture, resisted fingerprints and was easy to clean with standard screen cleaners.

The Apple’s glossy screen is tough on the eyes especially when forced to sit in a classroom with your back to the windows, a glossy screen can be tough to see because of the extreme glare and is nearly impossible to clean fingerprints off with standard screen cleaners. Popular Mechanics discussed the topic, so you can understand the difference between matte and glossy screen differences and see how others weigh in.

Weight

Lugging a stack of books, notepads and a laptop from one end of campus to the other can be tough on the back, so weight is a big factor in determining the preferred notebook. The HP laptop’s weight stacks up at 5.2 lbs, while the MacBook Pro we

ighs in at 5.5 lbs. However, I like the feel of the MacBook better than the HP because the weight feels more evenly distributed throughout the machine. HP’s feels heavier on one side, but that could be just my imagination. Although the MacBook adds another .3 pounds to my backpack, the discrepancy is minor. The laptopauthority.com website cites additional information on the positives and negatives of different laptop sizes and weights.

Available Slots



Side view of the HP


Plugging in USB storage, printers, mp3 players, digital cameras and an external mouse all at the same time is a monumental task for any computer, but hands down the HP takes on what a student would throw at it. The HP offers a power port, Ethernet, phone connection, SD, SC and SV ports, audio in and out, 3 USB ports and DVD drive. The MacBook Pro offers a power port, Ethernet, FireWire, Mini Display Port, 2 USB ports, SD card, and audio in and out, battery indicator lights and DVD drive.

Side view of the MacBook

Most students need a bunch of USB ports for printers, USB drives and an external mouse and clearly the MacBook fails. The MacBook struggles to offer students variety, neglecting other video card slots besides the SD and forgot about those still trying to get their parents to upgrade from dial-up internet. The HP laptop has all the bases covered.

Battery Life

Power outlets are scarce around most campuses, so battery life is another huge consideration. The HP laptop features a battery life of 4.5 hours and offers the option of swapping out with another external battery. The MacBook Pro, however, does not offer this option, but offers an internal battery with an impressive 7 hours of life.

For me, this issue is a bit of a toss-up. Although the MacBook has a longer battery life, there are consequences for only having an internal battery-namely the cost of replacing it when it eventually loses its ability to keep a charge, which is usually about 300 “cycles” for this computer. (See MacRumors.com for more info.) The benefit of the HP is that replacement batteries are relatively inexpensive and easy to install.

Price

It looks good. It has the basic criteria, so how much? The HP 6230 Series PC reigns in at $1709 at the manufacturer’s website. The MacBook Pro, from Apple’s website, claims they start at $1199, but while doing my research, didn’t actually find one at this price. I consulted a major electronics retailer, Best Buy and found they average about $1700, the same as the HP.

HP offers a 3 –year limited warranty on their laptop, quite lengthy for a manufacturer (HP). Apple offers a one-year limited warranty on their laptops, so you may want to consider additional coverage. Extended warranties may also be available, so consider the continued coverage and shop around, different retailers offer extended warranties, and verify that you understand what is covered and any deductibles you may be liable for.

All things considered, both computers have their advantages and disadvantages. Each student needs to carefully evaluate their needs and preferences before taking the leap to by a new laptop. Students should take plenty of time to familiarize themselves with the features of the laptop and ensure that they are comfortable before the semester begins. Other advice on selecting a new laptop is offered at howtodothings.com.
