Final WTC Summary

17 01 2012

A few things that I liked about this semester’s WTC class… I liked the variety of the lessons that the teacher gave us. For example, he taught us anything from creating a WordPress Blog, all the way to how to edit a green screen video and how to create cartoons. I also liked how the techer explains the day’s lesson quickly and effectively, then he lets us work quietly on our own until the bell rings.

The aspects that I didn’t like about the class I think were mostly because of my poor class-choosing. When I first signed-up for the class, I expected a more advanced and in depth lessons, like, creating web sites, working with HTML codes and stuff like that, but I guess I was wrong because we spent the better part of the semester creating accounts and signing up for different very basic activities that were assigned to us. I really wanted to take Computer Repair, which I think is also taught by Mr. Reichelt, to learn how computers are built, how they work and also learn more extensive and demanding lessons related to this, but it’s was a period-and-a-half class and there was no way I could fit that in my schedule without sacrificing all of my caf studies, lunch, and free periods, so I took WTC instead and turned out somewhat disappointed (I don’t mean to offend anyone, it just isn’t the class I wanted and expected).

My overall impression with this class is that it’s pretty much intended for people who just want to learn the basics of how to get more involved in the on-line world. Overall, I think it is a well-constructed class, again, for people who don’t want to get too much into all the technical parts of computers. I would definitely recommend this class to a friend. I have no recommendations for the teachers or the creators of this class.





WTC Final Project Script and Video Link

WTC Final Project Script

Me:        Hi, as my Web Tech Connections final project I’m going to create a

tutorial teaching you how to record and edit a green screen video.

For those people who don’t know what green screen is used for,

it’s generally used for adding an image or video to the background

of, for example, a recording of a person interviewing a soccer player,

to create the illusion of being at a different place, or to present the

replay of a good dribble made by the player. This also has some

disadvantages. The worst case scenario is that your clothes or any

other object in the video may bland with the green background and

it might make your final movie seem very unrealistic and made with

very poor quality, but with practice you can

eliminate this as an issue.

All you need is a digital camera with video capabilities, green screen

specialized fabric or any large piece of green fabric, the picture or video

that you want to use as the background, and advanced video editing

software, like Adobe Premiere Pro.

First you will need to hang or tape the green fabric to the wall that is

going to be used as the background for the video (make sure it is well lit).

Then, you have to record the video being careful not to record any part of

the wall that is not covered by the fabric. After that, you have to transfer

the video to your PC as an .AVI file; I have already done this. As you can

see, the file extension is .AVI.

Now we can edit the video. You start by opening Adobe Premier Pro.

Then you import both the recording with the green background and the

video or picture you want to use as the new background. Then you drag

the original recording to “Video 2” and the new picture or video into

“Video 1”. Highlight “Video 2”, click on the “Effect Controls”, click on the

“Effects” drop down arrow, do the same with “Keying”, and drag the

“Chroma Key” icon to “Video 2”. After that, you click on “Chroma Key’s”

drop down arrow, click on the eye dropper and then click anywhere on

the green background in the video. After the color is changed, adjust

“Similarity”, “Blend”, “Threshold” and “Cutoff” to your desired values.

After you’re happy with your video’s new background, finally you can

export your video by going to “file”, “export”, and “movie”.

Thanks for watching!

RSS Feeds

22 12 2011

RSS Feeds are a very simple way to stay up to date with your favorite websites’ most recent posts and updates. They can save you a lot of time and frustation because when you install and use and RSS feed reader, it automatically takes the newest posts from your favorite websites, and what it shows you is the title of the post and a short summary. The good thing about this is that you don’t have to go to every single website and browse through it to see if you like it, but rather you can see part of the article or post and if you are interested in reading it, all you have to do is click on the title. Most popular websites have RSS Feeds in their websites, including you wordpress blogs.

Google Reader is a free RSS Feeds reader created by Google. All you need is to have an existing Google account or sign up for one right on the page. The next and final thing you have to do is to go to your favorite websites, find their RSS Feed, and copy and paste the URL to the subscribe bar in Google Reader. You can subscribe to websites like ESPN, Engadget, Techcrunch and even personal WordPress blogs through Reader.

Can the iPhone 4S replace a “real” digital camera? Article Summary

14 12 2011

This article found at Ars Technica’s website investigates if a smarthpone’s digital camera can compare to a professional DSLR camera. They start the article by first taking opictures of an object with every generation of iphones, from the original to the 4s, and they compare them side by side. They conclude that anyone who has an iPhone older than the iPhone 4, they will be amazed by how much the iPhone’s camera has improved in the 4s. Then, they compare the iPhones 4S’s video capabilities with a Canon 5D mkII. After a nearly five minute video, it is concluded that under well-lit conditions the iPhone’s videocamera can be compared to a professional videocamera. For the last test, they compared the picture quality of 5 different devices, 3 smarthones and 2 DSLRs, by taking pictures of four different objects in different scenarios. They used the iPhone 4s, the iPhone 4, the Samsung Galaxy SII, the Olympus XZ-1, and the Canon 20D. After taking pictures of a flower arrangement, a building at sunset, two dogs in a poor-lit room, and a glass of beer in a bar with bad, dim lighting, they determine that the iPhone 4s’s camera is overall better than that of both the iPhone 4 and the Samsung Galaxy SII due to the combination of an updated sensor and the dual-core A5 processor making the iPhone 4s much faster to startup and take pictures than the other smartphones, but not as fast as the Olympus XZ-1. With regard to the remaining DSLR cameras, the ZX-1 and the Canon 20D had better image quality, largely due to having a much larger sensor than that of a smartphone and a bright maximum aperture 4x zoom lens.  The final conclusion is that you can do a lot more with a professional DSLR camera and people already used to these, would never change them for the iPhone 4s’s camera but there’s one thing you can’t do with them, put them in your pocket.





Photo Sharing Website Reviews

3 12 2011

Flickr

Flickr is one of the most popular photo sharing sites on the internet. With a free Flickr account, you are limited to upload 2 videos and 300MB worth of photos each calendar month.

While the 300MB bandwidth limit for photos is firm, they will allow a little leeway for video in case you encounter transcoding errors, sound sync weirdness, etc.

On the other hand, with the paid version of Flickr ($24.95 USD) you get: unlimited photo uploads, unlimited video uploads (90 seconds max, 500MB per video), the ability to show HD Video, unlimited storage, unlimited bandwidth, archiving of high-resolution original images, the ability to replace a photo, post any of your photos or videos in up to 60 group pools, ad-free browsing and sharing, and view count and referrer statistics.

Picasa

Picasa is also on the list of the most popular photo sharing web sites on the internet. Picasa was created by Google, which can be a good thing because you can connect your Picasa account with some other Google products to be more efficient.

Picasa is a free service by Google, but limits you to 1 GB of free storage. If you run out of free storage for Picasa Web, you can purchase additional storage that can be bought at a relatively low price and can be shared across various products.

Photobucket

Photobucket is a photo sharing web site which is also somewhat popular. Photobucket’s free service offers unlimited (for non-commercial purposes only) photo uploads and up to 500 video uploads in your account.

Other great Photobucket features include a free photo editor, the possibility of creating personalized gifts like T-shirts and mugs with your digital memories, and the ability to access Photobucket on your phone.

My Choice

If I were to choose from one of these three amazing photo sharing web sites, I would definitely pick Picasa. My decision would lean toward Picasa because although its free storage is limited to only 1 GB, it is one of the most popular photo sharing services out there, and its creator, Google, offers the ability to connect your Picasa account with very popular social services like Facebook, Twitter, Youtube and now, Google Plus. With Picasa, you can do all kinds of editing to your personal memories, including red-eye reduction, rotate, crop etc.

Netiquette Activity

Cyberbullying

Kelly isn’t popular and
a group of other students sometimes make fun of her clothes and accent.
Eventually, a teacher hears their comments and gives them detention. The next
day, Kelly hears that an email is going around school asking people to sign a
petition declaring her “officially worst-dressed,” with pictures from
her Facebook profile attached. The email is sent from an anonymous address but
everyone at school has seen it and is forwarding it to their friends.

If you were Kelly, how would you handle this situation?

I would tell an adult at school.

If you received this email, what would you do?

I would probably forward it. The right thing to do is to delete it.

Jason and Mark get into
an argument at school, and Jason backs down first because he’s afraid of having
a physical fight with Mark. That evening, Jason goes online and writes nasty comments
on Mark’s wall and pictures.

What risks is Jason taking by flaming Mark’s profile?

He’s taking the risk of getting hurt physically by Mark or someone else.

How else could Jason have responded to the argument with Mark?

He could have talked man to man and settle things.

If you were Mark, how would you handle the situation?

I would probably fight him.

Sam’s friend Carly used
a computer in library to check her email and forgot to log off when she was
done. As a joke, Sam used her account to send a crude joke to the principal and
several teachers and signed it “Carly”.

Who is going to get in trouble over this email?

Carly.

What should Sam have done when he noticed Carly had forgotten to log off?

She should have logged her off and told her about it later.

If you were Carly, how would you handle the situation?

I would make it clear, who sent the email, and then talk with Sam.

What could Carly do to protect herself in the future?

Be more careful about logging off in the future.

Too Much Information, Too Many Readers

Angela frequently uses
her personal blog to vent when she is frustrated or upset. She likes writing
about her feelings in her blog, instead of in a paper diary, because her
friends can read the entries and offer supportive comments. After a tough track
practice one day, she blow off steam by writing an entry called “Jill’s
Jiggles,” describing how her heavier teammate Jill looks when she runs and
wondering “why Coach Johnson even let someone that slow on the team.”
Angela doesn’t realize Jill knows about her blog until the next day, when Coach
Johnson calls her in to tell her that her comments were unacceptable, that Jill
is extremely hurt, and that he is suspending Angela from the upcoming meet.

Angela would never have made fun of Jill to her face. Why might she have felt like it was okay to do so
in her blog?

Because she felt she was safe behind the computer screen.

How might Jill have found out about Angela’s blog entry?

Someone in the school might have told her.

What could Angela have done differently to keep from hurting Jill’s feelings?

Tell Jill how she felt about her face to face instead of posting a blog for
everyone to see.

Was Coach Johnson infringing on Angela’s privacy by using the blog entry to suspend her from a track meet?
Why or why not?

No, because that is a valid reason for him to suspend her temporarily.

What are other possible unintended consequences of this blog entry?

A family member of Jill’s might have also seen the post.

Tyler is hoping to get a
summer job as a messenger at a law office, which will pay well and look great
on his college applications. His interview with the office supervisor goes
well. As a final check, the supervisor asks a law clerk with a Facebook account
to check out the profiles of the messenger applicants. The clerk shows her Tyler’s
photo album from the Homecoming game, which has several pictures of him
shirtless and making a rude gesture, with comments that show he and his friends
obviously think they’re hilarious.

If you were the office supervisor for a well-known, respected law firm, would you give Tyler the job?

Probably not.

Tyler’s Facebook profile is how he keeps up with his friends. How is it fair for the law office to judge
him based on it?

It doesn’t say anywhere that you can’t do it.

Who else besides potential employers might draw conclusions about Tyler based on his Facebook
photos? Think of at least three possibilities.

Tyler’s parents, a college or his friends and family.

What could Tyler have done to make a more positive impression with his online image?

He could have made his Facebook account private.

Lisa finds a bunch of
old photos that her mom has been scanning and saving on the computer. There are
several pictures of Lisa with Kristin, who were best friends until Kristin
moved away in 9th grade. For old times’ sake, Lisa decides to upload some of
the pictures to an album on Facebook. She thinks it’s funny to see their
haircuts and middle school fashion sense, and a couple of her current friends
post teasing comments on the pictures. Later, Lisa gets a call from Kristin,
who is really upset about the pictures. “I don’t want people to know what
a dork I was!” she tells Lisa. “I can’t believe you posted those. I’m
totally humiliated now.”

Does Kristin have any control over who posts pictures of her online?

No.

How could Lisa’s photos affect Kristin?

She might not feel comfortable with everyone seeing those pictures.

What should Lisa have done to prevent Kristin getting upset?

She could have asked Kristin if she was ok with her uploading those pictures.
