Continuing with a very source agnostic digital book strategy, Barnes & Noble has announced it will soon be offering an e-reader app for the Apple iPad.

The app will be designed specifically for the iPad’s tablet form factor, and will join B&N’s existing e-reader app family already available for Mac, PC, iPhone , iPod touch, and BlackBerry.

In other words, although the company is selling its own Nook e-reader device, it doesn’t want to lock potential book customers into a single platform or device. The company saysthat the goal is “providing consumers any book, anytime, anywhere.”

Like the other existing apps, the iPad app will give users access to the Barnes & Noble e-bookstore with more than one million e-books, magazines and newspapers, plus access of course to its existing digital library. The company expects to officially launch the app around the same time the iPad will be available, which should be April 3 if the existing rumor has any truth to it.

As publishers continue to flock to the iPad, what’s your current take on the e-reader versus tablet war that’s brewing? Can the two form factors coexist, or will tablets like the iPad steal the thunder from e-readers?

If you’ve never been to Hong Kong, and you’ve heard legends about the busy streets of the city, you can now see how it looks for yourself without leaving your comfy chair, as Google has launched its Street View service for Hong Kong.

The huge city has been covered extremely well; just zoom out of Street View, pull the little yellow Street View figure on the upper left side of the screen and you’ll see that most of the streets are blue, which means Street View is available there.

In addition to Hong Kong, Google Street View is now also available in the city of Macau, south of Guangdong province.

As conference season we begin thinking about all the things one might need to survive and stay connected with a busy schedule of travel and networking.Here are some of the apps which I believe will help you navigate, stay connected, and meet new friends when you attend a conference.

Accommodations

1. Priceline Hotel Negotiator

If you’re the ultimate procrastinator and you haven’t yet booked a hotel, even on arrival at the conference, the Priceline Hotel Negotiator app is for you. It pairs a great deal-finder with some comic relief in the form of William Shatner, the Priceline Negotiator. Just load up this app and shake — you’ll get a chuckle and some sweet hotel deals within a radius of your current location.

Cost: Free

Connectivity

2. Free Wifi Finder

So you’ve booked a hotel, but the room doesn’t offer complimentary WiFi (grr!). This app will use your location to find some local spots that offer free WiFi access. You can tailor your results from as near as 0.1 mile away, to as far as 40 miles. You can also filter results by categories such as libraries, cafes, airports, and hotels. You could probably couple this app with the Priceline app to make sure you don’t book a hotel room without WiFi in the first place.

Cost: Free

Local Stuff

3. RobotVision

Let’s say you’re in a city you’ve never visited before, and you want to find some cool stuff to check out. Sure, you could use Yelp, but where’s the augmented reality fun in that? My former co-worker Tim Sears created this app, and it’s a neat way to find anything from ATMs, to gas stations, to hospitals, to movie theaters. Better yet, you can also check out who else is tweeting around you locally, who is sharing Flickr images, and learn about local attractions via Wikipedia and Bing search functionality. Note, this app works best with the iPhone 3GS.

Cost: $0.99

4. Foursquare

Foursquare is a great way to see who else is hanging out at the same locations as you, and the gaming element of earning badges for check-ins is just plain fun. You earn points for checking in to multiple places in one day and for being adventurous and going to new places. You can see what your friends have been up to, leave tips and to-do items for other travelers, and tweet out your locations so that others know what’s going on. At any social media-minded conference, there’s sure to be a lot of location-based networking to be done through Foursquare.

Cost: Free

5. Gowalla

Gowalla is very similar to Foursquare in terms of location-based social networking, though I personally like Gowalla’s graphic layout better. Gowalla also allows the creation of user-generated “trips” that you can take, like the SEC Football Stadium Trip, or the Austin BBQ Bonanza (for those headed to SXSW). Again, you can see where your friends have been and also see who else is hanging out at your current check-in location. It’s a great way to meet and make new friends at a conference.

Cost: Free

Pics and Vids

6. TwitPic Uploader

The TwitPic app lets you do this in four simple steps: Choose a picture from either your camera or a photo album; Write a comment; Log into your Twitter account, and; Send away!

Cost: Free

7. Ustream Live Broadcaster

You want to share a really fun moment from the conference, but a still photo simply won’t do it justice. Or perhaps you want to share a little taste of a presentation, or do a live interview with another attendee. This app lets you stream live video from your iPhone directly through your Ustream channel. You can set it up to automatically tweet when you are live, as well as take instant polls from viewers. It’s an easy way to share some live moments with those who could not be there.

Cost: Free

Social

8. Facebook

This one’s a no-brainer. Who doesn’t have the Facebook app on their iPhone? Use it to keep up with your friends back home and share updates about your trip. Made a new contact at the conference? Just search for them in the app and add them as a Facebook friend.

Cost: Free

9. Brizzly

With Brizzly, you can connect to up to five Twitter accounts, as well as Facebook, and keep on top of everything. You can also save searches and upload photos. The only functionality I miss is the column layout from TweetDeck, but Brizzly certainly gets the job done.

Tip: Create your Brizzly account on a computer before you download the app, as it makes for quicker set-up on the iPhone.

Cost: Free

10. Glympse

Glympse is a really cool app that lets you share your location with others. But it’s more than just a geo-tagger — it shares your ongoing location. Basically, you can create and share your own “breadcrumb trail.” You can set it so that people will be able to access your location and follow your movements from within five minutes, and up to four hours. This is a great way to share which sessions you’re in with fellow conference-goers so they can easily find you.

Cost: Free

11. WordPress

This app works with both .com and self-hosted WordPress blogs. You can moderate comments as well as add and edit your posts from this app. It’s a nice little travel tool for bloggers who may not always have access to laptops or WiFi.

Cost: Free

12. beamME pro

You want to stay connected with your fellow conference-goers, but you a) Forgot to bring enough business cards, or b) Decided to “go green” and skip the paper cards all together. BeamME lets you e-mail, text, or tweet all of your contact information to someone instantly. BeamME users can easily reciprocate and shoot their information right back. Plus, your contact info arrives in a manner which can be downloaded in a nice, tidy vCard format.

Cost: Free

Google has just released an alternative player for Google Reader that gives those with a penchant for browsing news the ability to do so in an image-heavy, TV-like fashion.

Dubbed Google Reader Play, the new tool is an experimentalGoogle Labs project that presents stories one by one — based on their Recommend Items technology — using enlarged photos and auto-playing videos (in lieu of text) on a black backdrop. Viewers can redefine categories and star, like or share stories, with those behaviors further contributing to what Google displays.

Google Reader Play could be both an entertainment utility for browsing the web and a complement to yourGoogle Reader experience. Actions that you take in Reader or Reader Play are shared between the two products, and the recommendations in Reader Play are personalized based on the people you’re following in Reader.

Google Reader Play is certainly eye-catching, but it’s more pop than it is substance. In fact, given that Google Reader appeals to fairly narrow audience today, we believe the product was intended to up the entertainment factor and introduce Reader-esque features to a much broader set of users.

It’s nice to look at and worth a try; whether or not that’s enough to attract the attention of those outside the web/tech realm remains to be seen. We do, however, think that Google Reader Play on an iPad or actual TV set, say via something like Boxee Box, would be worth watching.

Bikers rejoice, Google has just added intelligent biking directions for more than 12,000 U.S. bike trails as a new option inside Google Maps.

The company writes that the new biking features will “include as much bike trail data as possible, provide efficient routes, allow riders to customize their trip, make use of bike lanes, calculate rider-friendly routes that avoid big hills and customize the look of the map for cycling to encourage folks to hop on their bikes.”

The new option now sits next to the current Google Maps standbys — car, public transit and walking — for online routing options, so users can select the new option from the dropdown menu to uncover a Google-recommended bike routes (likely sans big hills!).

You can also turn on a “Bicycling” layer via the “More” tab when zoomed into a particular city inGoogle Maps. The trails’ green hues should indicate terrain and road type. Dark green equates to bike-only, light green means there’s a bike lane, and dashed green means it’s a decent biking path but one without a bike lane.

Before you get too excited, we should note that as of right now biking is not an option in mobile apps, so make sure to plan ahead before you hit the pavement.

Web-based Twitter client Brizzly has three major developments to report: a new free iPhone app, a new Brizzly Guide (which gives trending topics on Twitter their own hub pages as permanent resources for information on the top Twitter discussion items over time), and the acquisition of WikiRank.

The Brizzly Guide is a user-editable area that fleshes out the backstory and adds contextual information to Twitter trends. Loading up the Guide shows the top 10 current trending topics at the left, and either a description of that topic or a prompt to be the first to explain the trend.

Taking cues from wiki-style user-editable sites like Wikipedia, the Brizzly Guide encourages users to curate the landing pages that will act as resources for current and past Twitter trends over time.

The free Brizzly iPhone app is available now in the App Store, featuring multiple account support, lists, photo uploads, saved searches syncing, classic-style retweet functionality, and support for the new Brizzly Guide with user-editable trends and news topics.

Further evidence of Brizzly’s adoption of wiki-style philosophy comes with the announcement of the company’s acquisition of Wikirank, an app that visualizes Wikipedia data and will soon, presumably, help visualize Brizzly data and build out a more robust Brizzly Guide. Wikirank displays popular and trending pages in a clean and easy-to-use interface. CEO Jason Shellen said of the acquisition, “We will be integrating Wikirank technology into the Brizzly Guide over the coming months,” so we should expect to see more from the Twitter client surrounding trending and data visualization in the near future.

Are you a Brizzly user? What do you currently use to monitor Twitter trends?

A new study from security firm Barracuda Labs provides some interesting insights into the state of the Twitterverse. Unfortunately for the microblogging startup, the stats say that most of its users aren’t very active.

The study looked at around 19 million Twitter accounts (PDF) in order to figure out how people are using Twitter. It started with one assumption: an active or “True” Twitter user has at least 10 followers, follows at least 10 people, and had tweeted at least 10 times. By that definition though, only 21% of Twitter users are active users.

There’s a great deal of interesting data in the breakdown. Only 26% of Twitter users had 10 followers or more by December 2009, while only 40% were following 10 people or more (in fact, a majority of Twitter users, 51%, were following less than five people).

In terms of tweets, the report estimates that 34% of Twitter users hadn’t tweeted even once, while a whopping 73% of Twitter’s users tweeted less than 10 times. That means nearly all of the tweets on the social network were coming from about 1/4 of the userbase. Power users dominate.

Barracuda Labs also analyzed Twitter’s growth over time, and the numbers are consistent with previous reports that show while Twitter grew like wildfire in early 2009, it has dramatically slowed down in recent months. Going back further to early 2008, the report estimates that the microblogging tool grew by just 0.31%. However, with the quick rise of media coverage and the influx of celebrities such as Oprah and Shaq, Twitter use grew by 20% in April 2009 before dropping off to 0.34% growth in December 2009.

While the news isn’t stellar, it isn’t all bad for Twitter — these metrics are moving in the right direction. A full 79% of users had less than ten tweets in June 2009, but that number dropped to 73% by December. 80% of users had less than 10 followers in June 2009, but that percentage dropped to 74% by December. If that trend continues, you’ll hopefully see a more diverse and active Twitterverse going forward.

Over half a million votes were cast to decide Barbie’s newest career. But even though Computer Engineer Barbie was developed in consultation with the Society of Women Engineer sand the National Academy of Engineering, the new doll’s appearance has sparked controversy.

While some have embraced coder Barbie, others have attacked the concept, saying that her pink laptop, sparkly leggings, and trendy glasses are “too feminine” to be realistic.

The critics imply that real coders aren’t feminine, and feminine coders aren’t real. But women shouldn’t feel like they have to stop being feminine to work in technology.

The First Computer Programmer Was a Fashionista

That’s right. The first coder was a lady. Ada Lovelace, over a century ahead of her time, is widely considered to be the first computer programmer. She was the first person to conceptualize and articulate what computers were capable of doing, and the first to foresee that computers could create artificial intelligence, generate graphics, and create music.

So, is Barbie’s outfit really that unrealistic? If the very first person to conceptualize a computer did so while wearing a girly up-do and a frilly gown, why can’t someone write great code while wearing pink platform crocs and a t-shirt that spells “BARBIE” in binary?

Women and Tech Today

This false dichotomy — that you have to choose between being feminine and “looking the part” of a mathematician or scientist — might be part of what turns girls off from math and science in the first place.

Or maybe girls don’t aim for careers in math and science because they don’t see role models. Even Ada Lovelace had role models. Her mom, the “Princess of Parallelograms,” loved math and gave Lovelace a very intensive math education. And Lovelace was also mentored by legendary female science writer and polymath Mary Somerville.

Or maybe girls are afraid of being the only woman in their technology courses or workplaces. If that’s the case, their concerns are certainly warranted. Not only are fewer women entering the information technology field, but more women are leaving the field mid-career.

A recent Harvard Business Review report, The Athena Factor, notes that “52% of highly qualified females working for SET [science, engineering, and technology] companies quit their jobs, driven out by hostile work environments and extreme job pressures.” These women report that they lack mentors and feel intense isolation in the workplace.

Coder Barbie and the Future

In 2010, maybe Computer Engineer Barbie would feel uncomfortable writing code on a pink laptop that matched her glasses in a workplace where she was outnumbered by men 25-to-1. But perhaps we should aspire to create a world where Computer Engineer Barbie and her gloriously pink accessories could realistically exist. Allowing a vision of an ultra-feminine computer engineer might, even subconsciously, open girls — and the rest of society — up to the possibility.

As a female math tutor, I used to feel the need to “tone down” my feminine style. I’d wear black slacks when working with my students for fear of appearing “unprofessional.” But then I decided to show my true fashion colors and wear my homemade dresses and sparkly barrettes when tutoring.

Since then, some kids have been openly relieved when they met me and found I didn’t look like their stereotype of a math tutor. The “math geek” stereotype in their brains was more intimidating and less fun than the real-life tutor wearing fuzzy pink boots.

You don’t have to choose between looking feminine and being good at math, science, and engineering. We need all kinds of people, all kinds of minds, and all kinds of geeks to solve our technology problems.

Facebook’s move into location has seemed inevitable for some time, and it now appears that the company will officially reveal its plans at next month’s Facebook developer conference.

According to The New York Times, the social network will incorporate location in two ways: (1) its own features for sharing location and (2) APIs to let other apps — like Foursquare and Gowalla –- offer location services to Facebook users.

Presumably, Facebook will make sure to address privacy issues with its location features — for example, perhaps with settings that allow you to share your location only with a select group of friends. The Times’ report doesn’t detail the specifics of such features, though it notes that the social network updated its privacy policy late last year in preparation for a location launch.

Facebook will be rolling out its location features to an enormous user base — there are now more than 400 million users of the social network in total, 100 million of which access the site via mobile regularly. The company also has its own native apps for all of the major mobile platforms. All of this gives Facebook’s location features an enormous edge over the competition.

The Times’ report suggests that the competition isn’t the likes of Foursquare and Gowalla, however, but rather Google and its huge base of local small business advertisers. Of course, the startups aren’t ignoring this opportunity either — earlier today, Foursquare shared details of upcoming features it plans to release tohelp local businesses utilize checkin data.

With Facebook entering the space, though, the other players will need to look to create value in ways beyond checkins and knowing where your friends are located at any given point in time. That’s why Foursquare seems to be so focused on partnerships and gaming, while Gowalla is making moves (as recently as last night) in virtual goods.

In any event, location remains the huge trend so far in 2010, and literally each day seems to bring new indications of which way it will all play out.

Spam and phishing have been ongoing problems at Twitter for some time, and tonight the company announced that it is stepping up its efforts to stop them with some new features, described as being able to “detect, intercept, and prevent the spread of bad links.”

In a blog post, Twitter writes that the protection works by “routing all links submitted to Twitter through this new service … even if a bad link is already sent out in an email notification and somebody clicks on it, we’ll be able keep that user safe.”

How exactly they do that, we’re not sure, but Twitter notes that you’ll start seeing short links using its own “twt.tl” URL shortener in direct messages and email notifications. As users who have been victimized by phishing scams (and those annoyed by the constant barrage of dodgy DMs) can likely attest, it’s a feature whose time has most certainly come.
