What are the dos and don'ts for using public Wi-Fi?




Happy Friday folks! I hope everyone is doing well. This week's topic is on the safety concerns of using public Wi-Fi (wireless fidelity) and was submitted by Margaret. For those of you who are new to using Wi-Fi publicly, pay attention because there is a lot of great information provided by our members that will likely help you learn the dos and don'ts. Let's get started.

Public Wi-Fi access (free or paid) is one of those services that I find invaluable, and I really can't imagine being without it now. In fact, a few times in an emergency, it saved me because I dearly needed Internet access. Margaret, I remember the first time I used public Wi-Fi access. I was skeptical and hesitant and never knew what to expect; after all, it was public and information in the airwaves can be captured. So I'm glad you asked and shared your concerns and want to know more about this topic. While I will let our members' answers address your questions (a few picks below in the Q&A), I do have a few pointers that I'd like to share. Margaret, you ultimately are the first line of defense for staying safe and a little common sense goes a long way. So make sure you have a firewall set up and running. Keep your antivirus protection up to date and your sensitive data secured--even separately on a drive that is not connected to your laptop when accessing public Wi-Fi. Free Wi-Fi service is great. Paid Wi-Fi may be a bit safer (offering you better protection since most have encryption in place), but a wired connection is always best. But then again, wired or wireless--there are no guarantees. And when accessing public Wi-Fi (free or paid), don't transmit anything that you wouldn't write on a postcard and send for the world to see, unless it is absolutely necessary. So with that said, good luck with your first experience, and I hope it is a positive one.

We have many great answers in place for you from our members--ranging from technical setup to ensuring your safety for using public Wi-Fi to some general good practices. So read on up and learn! For all members, if you have any additional dos and don'ts about accessing public Wi-Fi, please join us in this week's discussion and share a little about your public Wi-Fi experiences--good or bad. The more we advise one another, the more we'll all be safer using public Wi-Fi services with confidence. Thanks everyone! And have a great weekend!

Cheap camcorders




If you're accustomed to capturing clips with the movie feature on your point-and-shoot still camera or want something better than gimmick-marketed-for-YouTube models, you might be pleasantly surprised at the quality you'll get from these models. And one thing's for sure: cheap video is (usually) better than no video at all. Read more

What Everybody Ought to Know About Instructional Design




In an earlier post, we looked at how to build better courses by trimming out some of the content. Many of the follow-up comments and questions speak to your role as an instructional designer. In fact, it’s a question I was asked in a recent email:

What is the role of the instructional designer? And how do I convey that to my clients and subject matter experts?

As I was contemplating a response, I stumbled upon this video that does a great job illustrating the value of instructional design. Watch the video first and then I’ve got a few observations. If you don’t have access to YouTube, click the link below the video.

Click here to watch video.

As humans, we’re wired to learn and we’re always learning. There’s really not a time where we’re not learning. Learning is just what we do. And we have a natural way of learning that is not dependent on taking a formal course.

Learning happens through our experiences and through the things we see and hear. We learn in our quiet moments as we reflect on life. And we learn in our social interactions and conversations with others. And sometimes we even learn through elearning courses. :)

A formal course intrudes on the learner’s natural learning path. This intrusion is neither good nor bad. Essentially, we’re just circumventing the natural learning process by not waiting for the learner to stumble upon what we need them to know or do. So we manufacture a learning experience. And in that sense, the role of the instructional designer is to help the learners make sense of the new information they get.

The video above is an excellent illustration of some key points concerning instructional design. Imagine the video was the content of an elearning course. There’s a lot of information and a lot going. If you sat the learner down in front of the video and offered no guidance, who knows what they’d focus on?

Some might try to understand the big picture and spend time figuring out where they’re at and why they’re in two teams. Some might just observe the basketball skills. Still others might try to pick up clues listening in on the conversations.

There’s a lot going on and if you just left it up to the learner to figure out, you’d waste a lot of time and probably won’t get the results you need. So, instructional design is more than just an information dump. Instead it’s about helping the learners make sense of the information.

The Rapid E-Learning Blog - Instructional design is more than just putting information in front of the learners.

Fortunately, as you watch the video, the narrator does offer some guidance. He provides a basic objective: “This is an awareness test.” And he gives some direction to look for passes by the team in white. That’s easy enough to do.

For the moment, let’s discount the bear and just look at what happened. There’s so much activity and information that without clear instructions you’d focus on the wrong things. Because he gives clear instructions, you’re able to answer his question. In fact, while the moonwalking bear is obviously intended to catch you off guard, the reality is that the clarity of the instructions helped you see past the bear and focus on the goal of counting the passes. You were able to do what he asked despite the distractions of all of the other activity.

And that’s one of the critical pieces of instructional design. Because you’re manufacturing a learning experience, you don’t want the learners focused on twenty things. Instead, you’re trying to get them focused on very specific pieces of information.

The Rapid E-Learning Blog - Instructional design has clear goals and gets you learners focused on the right things.

Now let’s flip it around a little. Admit it. Unless you already saw this video, it was kind of shocking to think that something as obvious as a moonwalking bear could have passed before your eyes with you completely unaware.

There’s a lesson in there for us all. We can become so intently focused on our perspective that we miss the “moonwalking bear.” This is true of our clients, our managers, our subject matter experts, and even us. We don’t know what we don’t know.

This is why collaboration and good analysis comes in handy. It helps expose us to multiple perspectives and keeps us from counting passes, when the critical information is walking right passed us. And we’re able to pass that on to our learners.

The Rapid E-Learning Blog - Instructional design provides context and perspective.

Make a mental list of everything that is going on in the scene. How many people are there? How many teams? What type of ball? What are the people saying? What is the ethnic makeup of the people? Is that a police siren or ambulance? Which team has the best ball handling skills? The list could go on. And as you can see, there’s really a lot of information to collect and process.

Without instructional design, the learner might or might not get the information they need. Because of instructional design, you can get the learners to cut through a lot of extraneous information and get right to the important stuff.

What you do as an instructional designer is take the information and expertise of a tenured subject matter expert and deliver it to the learner. And in doing so, you compress the learning process saving time and money.

The Rapid E-Learning Blog - Instructional design compresses the learning process.

Now let’s look at the video in its entirety. It’s clever. I’ve watched it a few times and I’ve shared it with others. I’ve reflected on how to use the video as an illustration for this post. I’ve also used it in conversations with my kids and some friends. So the video makers have done a great job engaging me.

There something for us to learn here: good design engages us. When we’re mentally engaged, we’re more apt to remember and learn. And as you can see from the video, it’s not interactive. Yet it is effective.

Not all of our content can be cleverly packaged like this video. In fact, most people would rather have clarity than cleverness to start. And that is the first step in engaging your learners. The information needs to be clear and have real meaning and purpose for the learners. Once they understand why it’s important to them, they’ll be more apt to have a meaningful learning experience.

The Rapid E-Learning Blog - Instructional design engages learners with clear and meaningful content.

Learning is a complex process and there’s a lot more to be said about instructional design. The key point is that instructional designers provide value when they’re able to pull the content together to craft courses that are focused and meaningful. What do you think?

Remote access everywhere




With all of the fancy new portable devices like iPhones, BlackBerrys, and ultrathin laptops that can go anywhere, it's no surprise that VPN (virtual private networking) and remote-access software are booming markets. Products such as GoToMyPC, LogMeIn, and WebEx allow users to read documents, check e-mail, or install and run applications from anywhere in the world. Specialized software Simplify Media allows music fans the ability to listen to their iTunes or Winamp libraries wherever they may roam.

A new, free application called Remobo aims to combine its VPN and remote-access features with screen-sharing functionality found in programs like CrossLoop and Yuuguu. The software is still in development, so there are a few bugs here and there, but the all-in-one remote functionality that offers complete access to off-site PCs and share files with yourself and friends is a sure sign of things to come.

Always one of the first downloads





I recently got a new test Mac here at work. It's a MacBook Pro, which I'm using for our First Look video shoots (expect many new First Looks of Mac software in the coming weeks). People often ask me what is the first program I download on a new Mac, and the last few times it has been Adium X. Adium X is a solid chat program that can connect to multiple chat clients simultaneously. Once set up, I can chat with the IT folks if I'm having problems with my new machine, and I can quickly send messages to co-workers about what we're working on. The chat client is an indispensible tool in many users' working environments and Adium X is the best option for Mac.

Also this week, we have OmniGraffle, which helps you make flowcharts, graphs, diagrams, and just about any presentation, easy to understand and elegant. Our game this week is "Midnight Mansion," the popular 2D arcade platformer that's fun for all ages.

Alternative music software




There's been a lot of hype about the new iPhone and iTunes updates, but for those of us who don't use Apple portable devices, there's no reason to care. Frowny face.

However, aside from the leading music player software on Download.com--iTunes and Windows Media Player, at 58,707 and 44,495 downloads last week, respectively--there are a bevy of alternative digital music players/jukeboxes on the site. For example, user favorites Winamp and Foobar 2000 both work with the recently revamped Web service Last.fm.

Check out this week's collection of alternative digital-music players to see the other three that made the Top 5. (Hint: Zune didn't, and neither did Songbird.)

Integrating my computer as part of the entertainment center

Happy Friday folks! Many years ago the topic of integrating your computer as part of your home entertainment center was a fairly uncommon practice, and for the few folks who did it at the time, there were a lot of ooohs and ahhhs! All because back then broadband was not readily available. Hard-drive storage was at a premium, video cards with video connections were very limited and costly, and let's not forget the 2.0 sound cards. This short list of hurdles mentions just a few of the many that existed back then.

Today, the whole landscape has changed. Many prepackaged computer systems are meant to hook up to your home entertainment center, and operating systems are written specifically for the media center. The necessary hardware to hook it all up is now readily available and ranges from large capacity hard drives to video cards with an analog connection, and DVI and HDMI to cover the HDTVs, all the way to 7.1 channel surround sound cards. And with broadband available to most people, online purchasing of music and movies couldn't be easier, and it only takes seconds to minutes to download the content. With all this media at your fingertips ready to be viewed, played, and listened to from a computer and enjoyed as an integral part of your entertainment center, who wouldn't want to look into setting this up?

However, the question from member Phil is: Is it still expensive to do this? Is it difficult to build or set up? Is it possible to eliminate the physical media and incorporate it into the computer so he won't have to put up with the space that it all takes up? And last but not least, are there any new technologies or methods that he may not be aware of? Well, Phil, I've gone through the answers and let me tell you that while we didn't get the sheer volume of answers as we normally get for certain topics, we sure have a lot of great informative suggestions and answers from our members that we hope will give you and all the folks out there an idea of what is involved in integrating a computer into your home entertainment center. I have selected a few member answers to get you started in the Q & A section, but please read all the advice from our members. So grab a seat, read up, ask more questions if you have any, discuss, and learn from our helpful members. For those of you who have a computer as an integral part of your home entertainment center, I urge you to join us in the discussion and describe your system to us and how you got started and all set up. We are all here as a community to learn from one another, so your contribution to the discussion is appreciated! Have a great weekend everyone!

Onkyo's new receiver is even better

Do you know this free bird?

Is iTunes not your style? Just because it comes on your Mac doesn't mean you have to use it. The great thing about working with software is that there are many options available if there's some feature you wish you had, or another you could do without. Songbird is the open-source answer from Mozilla that offers tons of features to make music and media management easy. If you're looking for an alternative to Apple's popular media player, check out Singbird.

Also this week, we have AppCleaner, so you can make sure when you uninstall an application, you uninstall all of its associated files. Our game this week is "In-Poculis Mahjong Mac," a tile-matching game with a few twists that make it stand out from the rest of Mahjong game genre.

CNET TechSpecials

Happy Friday everyone! This week's topic is external hard drives and how to use them to back up your data. Before I start, I'd like to point out a few things about this topic. While Ben's questions do ask for recommendations on what external hard-drive brands are reliable and durable, it's almost a moot point to say one brand is better than another, because everyone will have an opinion on their favorites. And we could probably go in circles trying to debate what company has a better hard drive. So, for those of you seeking a brand-name external drive, read what has worked for our members and keep those thoughts in mind, stick with a well-known brand, and run with it. The second point I have to share (which is mentioned in many of our members' answers) is if you are planning on using an external hard drive to back up your important data, you better darn well have another backup of that backup--meaning do not trust your data on your external hard drive to be foolproof, because hard drives can and will fail. And if your only backup fails, you will be miserable! I cannot express this enough. Here is a post by member and forum moderator MarkFlax, on why external hard drives aren't the best backup.

In this week's topic of discussion, a lot of ground is covered by our member answers to Ben's questions--the answers range from brand recommendations and the methods folks use to back up their own data to many great software recommendations to synch up your data for backing up. For instance, member kknudson posts his advice on having a backup plan in place, whereas member rlessmue advises on the simple balance of life regarding storage volume. These are only a few samples of what has been brought to the table. All in all, with this information at hand from our member contributions, it's a great starting point to get a glimpse of what external hard drives are available and what are some available solutions to back up your data. So pull up a comfy chair, and digest and discuss this with your fellow members. I've picked out a few great answers in the Q&A section to get you started, but if you have additional experience or advice to share, bring it on! Thanks everyone for your awesome contributions. Have a great weekend! And don't forget to play it safe and back up your data if you haven't already!

Vizio's smallest plasma TV

Vizio is taking the flat-panel HDTV market by storm, slashing the dollar signs off its televisions, and becoming one of the best-selling names in the country. The VP322 continues this trend, sporting the smallest plasma screen available at 32 inches. While the set is not a particularly good performer, evincing inaccurate color and lighter black levels, it does avoid the uniformity and off-angle problems of similar-size LCDs. Read more

Better image browsing with PicLens

I've often said one of the greatest things about Firefox is the ability to use add-ons to improve your Web-browsing experience. I can't think of a better example than one of this week's download picks, PicLens. With this add-on for Firefox, whenever you perform a search for images on Google, Flickr, and many others, PicLens displays the results on a browseable 3D wall. Now offering video browsing on YouTube as well as shopping by image on Amazon, PicLens is the free add-on every Firefox user should check out.

Also this week, we have Pixelmator, an excellent image editor featuring filters, effects, a layer manager, and much more at a relatively low price. Our game this week is "Vendetta Online," a massive multiplayer online game in which you pilot your spaceship, explore, and fight your way through an enormous online universe.

Power up your photos with PicLens

Digital photos are one of the lifebloods of the Internet, and regular newsletter readers know that I'm always looking for new ways to manage my pictures and show them off to friends and family.

Users who are accustomed to the new iPhone/iPod method of "swiping" their way through photo albums and other jazzy Web 2.0 forms of navigation should take a look at PicLens, a collection of photo slide show tools that let users browse or create 3D slide shows that can include photos and video.

The PicLens browser add-ons--for Internet Explorer and Mozilla Firefox 3--highlight the image content of Web sites to let users whip back and forth through 3D galleries using mouse gestures instead of clicks. They also recently added support for Amazon and YouTube for 3D video galleries.

Even cooler, two free tools let you create your own digital photo slide shows for the Web. With PicLens Publisher, you simply select the photos you want to use, and the tool creates all the HTML and components you need to upload to your site. The PicLens Plugin for WordPress lets bloggers using the popular publishing platform easily add integrated, immersive slide shows.
