TechTips: Google Drive

Posted on April 30, 2012 by eric schnell

Google has finally released their long awaited competitor to Dropbox, SkyDrive, and iCloud, which they are calling Google Drive. Individuals can get up to 5GB of space for free but a premium service is available for 25GB at $2.49/mo, 100GB for $4.99/mo, and $49.99 a month for 1TB.

Users of Google Docs will find Drive very familiar. In fact, Google Docs is built into Drive. Just like Docs, one can collaborate with others on documents, can share content with others, and one can add and reply to comments and receive notifications when others have commented on shared items.

Users can attach photos from Drive to posts in Google+ and will soon be able to attach Drive content into Gmail, which can reduced the reliance on the use of file attachments. Work is also underway to allow third-party apps to access the content.

Drive supports a large number of file formats and includes the Google Drive viewer, which allows one to preview documents in 16 formats. Drive also tracks changes made to content so one view the revision history for the past 30 days.

Like other cloud storage services, Drive provides a single location at which to save and store documents and media content that can be automatically synced across multiple devices. Since Google is also behind Android, it’s mobile version of the service was released first. As of this writing the iPhone/iPad app had not yet been released. Drive also takes advantage of Android’s accessibility features so those with sight impairments can use the mobile app, eyes-free.

The desktop client works just like Dropbox’s. A folder is created locally which is used to store the content to be synced. One simply has to drag and drop an item in the Drive folder. Also like with Dropbox, the contents of the folder can be managed as any local folder. Since the desktop I first installed the client on is located behind a corporate firewall, Dropbox required the use of a proxy to allow real-time syncing. This was not the case with Drive. After installation, I dragged a file into the desktop folder and it showed up on the web client within 3 seconds.

Those with Google/Gmail accounts should visit drive.google.com/start to get set up. It may take a day or two for your account to be setup. There is plenty of online support available.

TechTips: Optimizing the New iPad

Posted on March 27, 2012 by eric schnell

It’s been a few weeks since the release of the new iPad and early adopters have uncovered a few “features” which can be optimized to get the most out of the device.

Data Plan Management

Edward Baid at USA Today wrote about how the new iPad’s 4G service can use up a data plan’s allotment very quickly. In fact, streaming an hour of high-definition video alone on either Verizon or AT&T’s4G data networks can use up an entire monthly allocation. One’s data allocation can also be eaten by using the 4G service to download apps already purchased for another iPad onto the new iPad through Apple’s iCloud. While the new iPad has a 50MB per app download limit on 4G. The data use required to move all the smaller-sized apps to the new iPad collectively using 4G adds up.

Verizon has advised users to use Wi-Fi when it is available to help extend the data plan since the iPad almost always defaults to a Wi-Fi connection when available. To ensure that you don’t use cellular data it would be a good practice to turn off Cellular Data within Settings when you don’t need it. Or, just shut deactivate the LTE service. Since the data plans on both AT&T and Verizon are prepaid one can select only what you think you’ll need and then add on or cancel data plans as often needed under the Cellular Data opinion in Settings.

Battery Life

The retina display on the new iPad is exceptional with great screen resolution and the enhanced color saturation. However, both features also require a lot of battery power. So much so that although the battery on the new iPad has 70 percent higher capacity than the iPad2 it still has the same run time.

Information Week posted several tips for optimizing the battery life:

Instead of using the auto-brightness setting, which adjusts the brightness to match the amount of ambient light, use the manual controls. The suggestion is to set the display set to about 25%-30% brightness, which is still plenty bright for indoor use.
App notifications use battery power even when the device is not being used since they turn on the display and use battery when they arrive, even for 5 or 10 seconds. In the Notifications setting menu, turn Notifications “off” for as many apps as possible. For apps which you must have notifications, turn the View on Lock Screen setting off so the display is not turned on when notifications arrive.
Wireless radios rank second to the display in battery use. The new iPad defaults to using Wi-Fi when available. If you have access to Wi-Fi turn the cellular radio off completely. Turn off Bluetooth unless you’re actively using a Bluetooth accessory, such as a keyboard.
Location services (GPS) also drain battery. Turning location services off completely can extending battery life. If certain apps need location services one can just limit notifications to only those apps that must use them.
The iPad uses battery when it wakes itself up to check for email or other synced data (such as calendar/contacts) To increase battery life turn off push email entirely or sync once every 15, 30, or 60 minutes. Better yet, have it sync manually and it will only check for mail only when the email app is opened. This is also a good strategy for lowering data plan usage.

Test results from DisplayMate Labs conclude that the battery life indicator on the new iPad displays 100% charged when it is really at about 90%. The labs suggest that if one stops charging the new iPad when the battery indicator says 100% you won’t get the maximum running time. To maximize the battery keep your iPad plugged in for an hour or so more after the display reads 100%. The lab also discovered that when the new iPad is fully discharged it takes 5.5 hours to charge. That’s only if the new iPad is off or in sleep mode. The labs estimates that recharging while using the new iPad, with the display set to maximum brightness, will take about 20 hours. It would be a good practice to charge the new iPad overnight or when you’re not tempted to pick it up while it is charging.

Portable HotSpot

The Verizon version of the new iPad launched with the ability to use the device as a portable WiFi hotspot, allowing other deives to sdhare the network connection. There is an option of sharing the data connection using Wi-Fi, Bluetooth, or a USB connection.AT&T has indicated that they are working on this feature. Setting up the new iPad as a hotspot is fairly simple and requires an active cellular data plan.

Of course, having more devices using the connection will also eat up the data plan allocation.

TechTips: Optimizing EndNote to Access Full Text

Posted on April 28, 2011 by eric schnell

Many researchers take advantage of bibliographic management soft to search online bibliographic databases, organize their references, images and PDFs, and to create bibliographies and figure lists. Although the a central site license provides campus access to RefWorks, many researchers instead use EndNote.

Bibliographic management tools like EndNote can not only help researchers to manage references, they can also be used to search for full text. To increase the liklihood that EndNote will find full text resources requires the proper configuration and an understanding of certain limitations:

Finding full text requires the OpenURL path of http://olinks.ohiolink.edu/olinks.php (see config at right)
Finding full text requires authentication with URL https://library.osu.edu/Shibboleth.sso/Login?target=http://library.osu.edu/ (see config at right)”
Searching and finding full text may work better on campus than off due to different resource authentication methods and licensing agreements.
EndNote offers several pathways to some databases, such as Medline. However, OSU Libraries may not have access through each of these pathways.
Thomson-Reuters offers excellent FAQs, tutorials and webinars at http://endnote.com/support/ensupport.asp
Additional bibliographic styles can be downloaded at http://endnote.com/support/enstyles.asp
EndNote is available at a discount price of $79 at the campus WiredOut store.

TechTips: The “Quora” Question and Answer Service

Posted on January 10, 2011 by eric schnell

One of the hot emerging social media sites is a service called Quora. Started by former Facebook employees, Quora is a “continually improving collection” of questions and answers that are user created, edited, and organized. Quora aggregates all the questions and associated answers while allowing users to collaborate on any of them.

Yes, question and answer services have already been done to death, such as Google Answers and Yahoo! Answers. However, Quora has a much more authoritative tone and has a better understand of the whole social element than the predecessors. Users can follow/be followed buy other users (no spambots!) and one can also follow subjects and individual questions of interest. Since the service does leverage existing social media spaces such as Facebook and Twitter, new users will quickly see familiar faces, which helps to validate the service. As with other social media outlets, contributors can use the service to establish a reputation within specific areas of expertise.

Once logged in (one must have an account to use the service), users type in keywords to find questions on subjects. The search bar provides auto-suggestions that helps to identify questions and topics that have already been asked relating to the keywords. The user interface does take a few tries to figure out in part since the label “Ask Question” makes one assume queries must be in the form of a question.

Since the developers would like new question entered into the system to be properly constructed, the system requires new users to successfully identify properly formatted questions before they can pose their first question. All new Quora users should read this post first before jumping in and answering questions. One of the more interesting features is that any member can edit another member’s question.

Users can not only answer any question as well as comment on the topics attached to the questions and answer other member’s answers. The site suggests that users summarize links and references in a sentence or two. A Digg-like rating system allows the more popular answers to move to the top of the list.

Pundits will likely view Quora as they did Wikipedia in its early days since Quora also relies on the users for quality control. The primary difference being that the answers in Quora are directly attributable to specific individuals.

As was the case with Wikipedia, Quora has the potential to turn into a useful starting point for any line of query and result in a new type of search engine. Or, it could turn into ” a continuously spamming collection of unanswered questions created, answered, and organized by no-one that uses it”.

TechTips: Read It Later With Instapaper

Posted on October 21, 2010 by eric schnell

How many times a day do you come across articles or interesting items online that you don’t have time to read at that moment?

The most common method of saving such content is to create browser bookmarks. However, over time browser bookmark lists can become very long and unorganized. Another common approach to saving content is to drag shortcuts to the desktop. Again, over time the desktop can become loaded with shortcuts. Another challenge is that if you happen make use of several web browsers, or computers, the content saved one one is not available on another. In the end, what was once interesting content eventually gets lost in the clutter.

instapaper logo

One solution to addressing this problem is Instapaper, a “simple tool to save web pages for reading later.” This service allows one to save content accessed on one browser or device for later reading on a different browser or device.

After creating an Instapaper account, the user installs a browser ‘bookmarklet.’ When content is being view, one clicks on the Read Later bookmarklet button. A “Saved!” message will briefly appear in the corner of the page as a link to the content is save on the users’ account.

All saved content is saved and accessed from the Instapaper site or app. An RSS feed is also available for all the items that have been saved allowing the content to be accessed from any RSS reader.

Some additional features:

If you use folders, each folder has a bookmarklet to save pages directly into it under the Folder Tools section in the sidebar.
Provides Kindle-compatible files containing the text versions of your saved pages that can be transferred via USB.
The bookmarklet also works on Apple mobile devices: just add it to your bookmarks in Safari, and it will be synchronized to the bookmarks folder. Many Apple applications make use of their API to provide support for sending pages directly to Instapaper.
Other Instapaper users can subscribe to a folder of your Starred items if they know your username.

As with many cloud-based services, Instapaper has no outside funding or corporate backing. So, although the service is free, it is ad-supported.

TechTips: URL Shortening

Posted on July 19, 2010 by eric schnell

URL shortening is the process of taking a long URL and turning it into, well, a shorter one.

For example, instead of using the 168 character URL http://library.ohio-state.edu/search~S7/?searchtype=a&searcharg=+gee+e+gordon&searchscope=7&SORT=DZ&extended=0&SUBMIT=Search&searchlimits=&searchorigarg=ae+gordon+gee, one could use the 27 character shortened URL of http://tinyurl.com/geebooks.

The mechanism for resolving a shortened URL is relatively simple. The long URL must first be registered with a URL shortening service. The service either generates a random shortened URL or the user could enter a custom ‘alias.’ The service maintains a database that contains the long URL and the shortened URL. When a web browser is directed to go to the shortened URL, the service performs a redirect of the shortened address and the browser is sent to registered long URL. There are many, many services that create shortened URLs, most notably TinyURL.com.

Shortened URLs are essential in communication channels where there is a limit to the number of characters that can be used, such as with Twitter. Shortened URLs can be useful when reading longer URLs aloud to customers over the phone, including URLs in printed materials, or when adding URLs to video displays or embedding them within presentations. Shortened URLs are also much easier to enter into mobile devices.

One concern with URL shortening is that the domain of a URL plays an important role in identifying the authority of a resource. Which URL would you trust: http://tinyurl.com/geebooks or http://osu.edu/geebooks? Simply put, brand/name recognition – the authority of an organization - disappears since the domain is hidden behind the shortened URL. Web users must select the shortened URL and actually visit the redirected site before discovering the site’s authority.

One solution to this authority issue is the growing use of branded URL shortening services. An example is Flickr. Each photo page also get a shortened Flickr URL. The domain flic.kr is owned and operated by flickr.com so the shortening service is as reliable as the Flickr service. Therefore, when someone navigates using a link with the domain flic.kr they know they will get a Flickr photo page, not a redirect to a site containing malware.

Another problem with using cloud-based services is when the services die, as tr.im almost did in August ’09, all the shortened links would break. The person relying upon the service would have to re-enter each URL into yet another shortening service, which could also die. This would be a big problem if the shortened links generated by the service were to be included in printed publications.

Work is underway on an OSU branded URL shortening service that not only helps to promote and support the institutional brand by creating authoritive shortened URLs, but also increases the chances that carefully crafted custom links will live a longer life.

TechTips: Extending Cellphone Battery Life

Posted on June 16, 2010 by eric schnell

I recently purchased a new Android-based mobile phone. I spent the first day checking out all the features and options, downloading a bunch of applications, and experimenting with the GPS and location-based services. It didn’t take very long to notice the battery drained relatively quickly.

The problem with the current generation of phones is that all the neat features also eat away at the battery. They have large bright screens. They have connections for 3G, Wi-Fi, and GPS. They connect to the Internet. They have applications that run in the background to provide alerts.

Simply put, cellphones spend a lot of time connected to their chargers these days.

Here are a few things one can do to extend cellphone battery life:

Check the settings of your background applications and notifications: Having email, Twitter messages, Facebook updates, and calendar appointments delivered minute-by-minute is perhaps the largest battery drain. Resetting the email polling interval from every 5 minutes to an hour will do wonders for battery life. If you keep multiple applications “open” for quicker access or alerts, run them only as needed. There is no need to get storm alerts if it is going to be 80 and sunny.

Turn off roaming/3G/4G when not needed: If you have good coverage and are mostly usind the phone for talking, or get only occasional email updates, there isn’t a need to keep such a wide wireless connection open.

Use location-based services onlt when needed: Having the phone constantly look for new Bluetooth devices, Wi-Fi hotspots, GPS positions definitely eats up battery. Find out how to turn these things off on your phone, or automate their use. Add shortcuts and widgets to the homescreen to make it easier to control the radios.

Play with screen time-outs, brightness, and backlight: Adjust the setting for how long the screen stays lit after a quick check of the clock. Turn on automatic brightness so the screen auto-adjusts in light and dark environments rather than having brightness turned all the way up. Alternatively, lower the default screen brightness.

Keep it cool: Avoid keeping the battery at full charge and high temperature. This is the case when placing a cell phone or spare battery in a hot car. Keep it out of your pocket and away from your body heat whenever possible.

Turn off live wallpapers and vibrate; lower ringer volume: They do use processing power and eat into the battery life.

Please leave a comment if you have any other tips for extending smartphone battery life.

TechTips: What is Website Clickjacking?

Posted on May 22, 2010 by eric schnell

Clickjacking describes a Web page / browser attack where user initiated mouse clicks trigger an unintended action, such as disclosing passwords and other confidential information. This action is done primarily by hiding clickable Web page elements inside an invisible frame. Clickjacking can affect all the major Web browsers — Internet Explorer, Firefox, Safari, Chrome, and even Opera by exploiting vulnerabilities in embedded code or a script on a Web site.

For example, the attacker may create a set of “dummy” buttons that are loaded transparently on top of another page. The visitor thinks that they are clicking on the visible buttons when, in reality, they clicking on the buttons located on the hidden page. Another technique is known as text injection, where attacker controlled text is entered into a field on a Web form.

One of the more recent clickjacking attacks was made on Facebook in 2009.

In a recent white paper, Paul Stone, researcher for UK-based Context Information Security LTD, discusses new attacks that dupe users into activating malicious links on websites without their even knowing it. website developers should read the paper. There is also a browser-based clickjacking tool available to show website owners how easy their site could be clickjacked.

While much of the management against the risk against clickjacking involves best practices by site developers, there are a few things the Web user can do.

Firefox users can download the “no script” plug-in. It allows JavaScript, Java and other executable content to run only from trusted domains of your choice, guarding your browser from some clickjacking attempts.

Internet Explorer 8 users can also mitigate the impact of attacks by logging out of sensitive websites when not in use or by using independent InPrivate Browsing sessions, which lets the user control whether or not IE saves browsing history, cookies, and other data.

Google Chrome now supports a security feature that helps sites defend against clickjacking attacks

While not immune to clickjacking attacks, Opera appears to have a decent built-in prevention.
