Switch from Teaching Word Processing to Teaching Web Processing

If you’re like me, one of the first computer skills you were taught in school is how to use a word processor. We all mastered the art of formatting words for the printed page because we were still using computers in a paper-based world. As more business and education activities move online, we are spending ever more time writing in web-based text editors, where our ideas are being automatically encoded into divs, spans, ps and ems– a language that too few of us speak fluently enough to reset the margins or change the font size.

Take Dramatic 3D Screenshots of Websites with Firefox's Tilt Plugin

If you do a lot of presentations or tutorials about technology, you probably have to take screenshots of websites to illustrate your ideas. I really like to add a “wow” factor to my presentations whenever I can do it gracefully, and I’m already seeing the possibilities with Mozilla Hacks’ new project, Tilt. It uses the very latest in HTML5 WebGL technology to render web pages in 3D, showing its internal structure (the DOM) visually. While that’s all cool and geeky, it also means that you can take dramatic-looking screenshots of websites to show in your presentations.

How do you do it?

  1. Go download the Tilt plugin for Firefox.
  2. Navigate to the website you want to screenshot
  3. Pull down Firefox’s Tools menu and invoke Tilt
  4. Position your website in the most awesome way possible
  5. Shoot and edit your screenshot with your favorite screen capture software like Jing, Skitch, or good ol’ Grab in OSX
  6. Drop that screenshot into your presentation, document, or whatever creative piece you’re working on!

It’s really that simple! I’d love to see what you do with this tool– please leave links to your 3D presentations in the comments!

Make a "Hard to Guess but Easy to Remember" Password for Greater Cloud Security

Remembering passwords

Image by hardeep.singh via Flickr

In my last post, I recommended using a password manager like LastPass to help you create strong, unique passwords for all of the different sites you use. If you don’t like the idea of storing passwords in the cloud, the next best way is to create a mnemonic password formula. The way it works is to create an easy-to-remember “formula” that enables you to use a different strong password on each site. It consists of a strong password that’s the same on every site(so you can remember it) but with a different component for each site.

 

Here’s one method:

Take the first letter from each word in a favorite song lyric. I just happen to have “Panic” by the Smiths on right now. The first line is

Panic on the streets of London/ Panic on the streets of Birmingham

If you take the first letters from each word, you get:

PotsoLPotsoB

Already, that’s pretty cryptic because it’s not a dictionary word and it has both upper and lower case letters. It’s also easy to remember because I can just hum it to myself. Then you can add numbers and punctuation to make it stronger

PotsoL/PotsoB4220

I added a slash where it would come in the lyrics, and I put my dog’s birthday backwards. Now I have a very strong password that’s easy to remember. This is the part I commit to memory. Very strong, but it doesn’t solve the problem of having different passwords on each site.

Next step is to add the first three letters of the site into the password. We’re going to have [memorized password] + [first 3 letters of site name].

My Facebook password would be PotsoL/PotsoB4220+Fac

My PayPal password would be PotsoL/PotsoB4220+Pay

So what you end up with is a very long and secure password that’s different on every site and easy to remember. This is just one way of creating a mnemonic password, but it’s the best way I know to do this. Of course, the trick is that you have to be consistent in your formula. If you don’t stick with the exact formula it’ll be a nightmare to recall it. Not to mention what a hassle it is to have to type this every time.

Good Security Practices Keep You Safe(r) from Hackers when Using Cloud Tools

password

Image by fixedgear via Flickr

Friends and colleagues have been expressing doubt about entrusting their data to “The Cloud”, especially in light of the recent high profile attacks on the CIA, the Senate, and Sony (among many others).  As educators are increasingly adopting cloud-based tool in instruction, it’s very important to have a clear idea of what we’re really talking about here, and to clear up as much FUD as possible.

“The Cloud” is not one thing—while the many recent hacks are being lumped together in the mainstream media, there were different circumstances in each case, and each teaches us a different lesson about online security.

The Sony hack was a particularly bad one because they stored all their users’ passwords in un-encrypted text. Since so many people use the same password for multiple online services, it’s likely that your playstation password is also the password you use for your email, your bank, and your paypal account. Hackers got these poorly-protected passwords, Sony didn’t notify the public for 5 days, so the hackers had a field day with the data and got into several other accounts.

Lessons:

1. Use unique strong passwords for all of your different “cloud” accounts. This way if one password gets compromised it does not open up all the rest of your accounts as well. Using a password manager like LastPass can help (I swear by it), or you can also create a hard-to-guess-but-easy-to-remember password formula.

2. Don’t store your passwords in your browser’s memory. Again, LastPass is great for this because it encrypts them.

3. Investigate the security practices of cloud services you trust with your sensitive data.

Some of the most high-profile attacks by LulzSec (like the CIA & Senate website attacks) were Denial of Service (DOS) attacks—meaning that they did not actually gain access to any unprotected data. A DOS basically floods a website with so many requests that it can’t process them all and the website goes offline temporarily. It’s like getting everyone you know to go ring someone’s doorbell one after another until they stop answering the door. It might drive that person nuts, but it also doesn’t open the door. These attacks are now commonly performed with botnets—large armies of computers infected with viruses that allow one hacker to direct millions of computers (often unbeknownst to their owners) to access the target website and bring it down. Large cloud services like Amazon and Google are designed to withstand these attacks by re-allocating their enormous computing resources to meet all the requests and keep the websites up and running during the attack. Smaller servers without as many resources are most vulnerable to DoS attacks.

Lesson:

1. Use virus protection software on your computer and perform all necessary updates as soon as they’re released.

2. Keep your browser & plugins up to date. This tool will scan your browser and plugins for security vulnerabilities.

Of course, LulzSec and others have been perpetrating more sophisticated attacks than DoSes. They have been exposing security flaws in their targets’ websites which will eventually lead to better security practices across the board. I know it has forced me to be more careful with my personal security practices and it has been pretty easy to do. (My data was exposed in the Sony hack and last year’s Gawker hack, but I’ve taken some simple steps to minimize the damage that anyone can do.)

In the meantime, there is a lot you can do to protect yourself online—even in “The Cloud”.

Free Tools, the Distorted Web, Privacy, and Your Students' Critical Thinking Skills

Until I saw this TED talk, I didn’t care much that free Web 2.0 tools like Google and Facebook were collecting massive dossiers of information about my online habits. I thought they were just using it to serve me more relevant ads and improve my user experience. It seemed like a small price to pay for access to the many awesome online communication and collaboration tools they provide.

In this talk, I learned that sites like Google and Facebook actually skew your search results to show you different information based on what they think you’ll like. The speaker shows how different people got different Google results when searching for “Egypt” in the wake of the politial protests there this spring. Rather than giving you an accurate view of hits relevant to your search, these sites favor certain sites over others in an attempt to show you content it thinks you’ll like.

 

Seeing this talk reminded me of the billboard I recently saw near the Bay Bridge in SF, loudly proclaiming:

DuckDuckGo.com Billboard "Google Tracks You. We Don't."

The Experiment

I decided to go Google-free for a week and use DuckDuckGo for all my searching needs to see how different the search results would be.

I did a very interesting little experiment: I searched “income inequality” in DuckDuckGo vs Google (see links for results). I didn’t see much difference in the search results until I noticed a search result in DDG that I don’t agree with– that Income  Inequality “doesn’t matter“. Anyone who knows me (and who knows me better than Google?) would take it for granted that I think income inequality is a problem. Of all the different things one could say about income inequality– I thought we (as a society) were all on the same page that it’s not a good thing. I probably fit squarely inside some Google framework of a Bay Area, liberal educated white middle-class NPR listener who would be shocked and horrified by such callous libertarian thought. I think this is part of what the speaker in the TED talk was getting at– that internet filtering removes viewpoints that challenge our own. My time with DDG is making me wonder if my search results help reinforce my certainty that my view of reality is the correct one.

 

This little revelation led me to try the mother of all divisive search terms: “Abortion”.

The Google Results Page:

abortion   Google Search

The Google results seemed a little too encouraging for me to get out there and get an abortion– a large part of the page was taken up telling me where I can go to get an abortion in my neighborhood right now! I’m just hoping that these search results are calculated based on my liberal politics and not by some measure of my overall value to the gene pool!

The results were heavily oriented to my physical location, giving me news and vendors of abortion in Oakland. There was news about the political struggle around abortion, but they presumed that I had already made my mind up about the issue, and that I’m “pro”.

The DuckDuckGo Results Page:

abortion at DuckDuckGo

By contrast the DuckDuckGo results featured a spectrum of search results from Conservapedia to ProChoice.org, RonPaul.com to the HuffingtonPost by way of a decidedly unfiltered mixture of different viewpoints along the way. It did not presume that I already knew anything about the subject, and so it gave a mixture of search results that offered several different ways to look at the issue.

If I had any uncertainty at all about this important decision, I would rather be looking at search pages that don’t make that decision for me ahead of time, wouldn’t you? Now of course abortion is an extreme example, but the fact that DDG returns such diverse search results gives you an appreciation for how many different perspectives there are on reality, and how that diversity can look in search results.

 

I used DuckDuckGo for a week as my desktop search engine of choice, replacing the default search engines in my Firefox, Chrome, and even my Android phone’s default search engine. Generally the results were relevant, complete, and quick (but not instant like Google Instant). I didn’t feel like I was suffering a performance drag– unless I was looking for something local. When I search for Oasis Market, Google just knows that it’s the one in Oakland, while DDG returns the one in Minnesota. This was especially annoying when searching it from my Android phone– the experience of trying to get directions to a spot in SF via voice search was enough to put me off DDG altogether.
I really fell in love with the !bang shortcuts– they allow you to search many 3rd party sites and topics from DDG just by entering a code like !g or !facebook before your search query. They have shortcuts for almost any major site you can think of, as well as great generic !bang searches for images, file types, and programming languages. The selection is staggering and has revolutionized the way I search the web period. This alone makes it an essential service and the very best way I’ve found to search various sites quickly, all within my search bar.

Eventually, despite its very capable service, I was relieved to get back to my hyper-relevant, instant-searching, location-aware overlord with a capital G. I’ve been playing with it and I’ve figured out a way to easily call up DDG with a keyword in Chrome so I can use it when I want it and skip it when I don’t. Using the technique that I discuss here I made a keyword for DuckDuckGo search in my Chrome Omnibar. This makes it so I can simply type “ddg” before my search terms and Chrome will search DuckDuckGo instead of Google. This is nice because while Google remains my default search engine for when I’m feeling googly, I can just append “ddg” before my search terms and I’ll get DuckDuckGo results. I really think this is the best of both worlds, and it’s the new way I search the web.

 

So What?

Like me, you may not worry much about the profiles that companies are amassing about you. It does seem to be a small price to pay for the incredibly useful tools like Google Docs, Facebook, and Google search. However, these services are making lots of money collecting and selling your personal data to advertisers– Lifehacker aptly puts it: “If you’re not paying for it, you’re the product“. While I have (so far) felt ok opening myself to this kind of vulnerability, it gives me pause to think that I’ve been recommending that my students do the same. Is this responsible for teachers to do when the real-world consequences of exposing personal data are not fully understood? Will we one day find ourselves regretting that we gave up so much of our personal data to cloud companies, and when we do, will we feel responsible that our students did it too? Should teachers seeking students’ liberation and empowerment be on the vanguard of software efforts that preserve and enhance user liberty and control such as DiasporaFreedomBoxLockerProject, and Free/Libre Open Source software?

 

Aside from privacy issues though, the Orwellian issue of how our experience on the web is distorted has implications for students’ development of critical thinking skills. Central to critical thinking is the idea that reality can be viewed from very different lenses and perspectives. If our search engines and social networks (for many, their web portal on the world) provide us with a distorted view of reality, do we lose the ability and the desire to consider divergent viewpoints from our own? If students’ online experience can be tailored to their tastes like an iTunes Genius playlist, what are they missing out on? Where is the chance to see the unexpected, the infuriating, and the serendipitous? Don’t we have a right to steer them towards experiences that push them out of their comfort zones? And if so, should we be starting with the search engines and software tools that they will depend on after they’ve left our classes?

I’d love to hear your thoughts in the comments…

Doit.im > Project-Based ToDo List App for Project-Based Learning #PBL

One of the great strengths of Project-Based Learning (PBL) is that students learn the skills they need to successfully see a job through all the way to completion. They learn to break large tasks into smaller ones, prioritize and sequence those tasks into manageable chunks that can be executed in one sitting. They also learn to delegate tasks to group members and to check-in to confirm that those tasks actually got completed. This is a set of skills that many students (and adults) struggle with, and are skills that turn great thinkers into great do-ers. As students master these skills, it makes sense to introduce them to technology tools that support the kinds of project management tasks they’re doing.

Screenshot of DoIt.im

DoIt.im is the best to-do list manager I’ve found for managing to-do’s as part of larger projects. It allows you to create projects and list out to-do tasks to help you get closer to the goal. It also allows you to enter your group members’ emails so you can send them tasks and see when they’ve been completed. Your tasks can be viewed on a calendar by due date, or in various lists according to different characteristics of the task (due date, context, project, contact, etc).

Doit.im is designed to be compliant with David Allen’s influential productivity manual, Getting Things Done (GTD). It’s a great way to get students interested in this excellent method for handling busy workloads at school and work.

The tool has an HTML5 web app which syncs to apps for iOS, Android, and Adobe AIR (for Mac, Windows, and Linux desktop computers). Its eye-candy UI compares favorably with other attractive new to-do managers like Wunderlist and Springpad, while its feature set is more complete… more akin to my old favorite RememberTheMilk. The thing I prefer about DoIt.im is that you don’t have to dig down too deep into the user manual in order to find a workflow that supports project-oriented workflows. Everything is simple and organized towards that way of working.

I’m also excited about using this tool in an organizational setting– the same project-based orientation can help work departments keep everyone together and focused on shared initiatives.

Cultivate Your Personal Learning Network Part II: Showing What You Know

In Cultivate Your Personal Learning Network Part I, you learned to find and organize information that will teach you, challenge your ideas, and help you stay on top of interesting new developments in your areas of interest. The second part of the Learning Loop is the “Outputs” stage. Here you will need to get in the habit of adding value to the information that comes in to you in whatever way works for you. That could mean writing your reactions to an interesting article you read, making lists of bookmarks you find to make it easier for others to find relevant information, video-ing yourself demonstrating a skill you learned, or sharing resources with people you think could benefit from them. What you do is as unique as your skills and interests are, but the focus should be on sharing your learning with others who could benefit from it. Though this practice can benefit you professionally, think of it as doing well by doing good first. This post will look at why you might do this and how you can do it easily without adding a lot of extra work for yourself.

 

Outputs: Showing What you Know

Not too long ago, I got an appointment with a new doctor, showed up, and was asked to wait in his office for several minutes before he could see me. I noticed that he had many objects in his office that were meant to reassure patients that “he knows his stuff”– his med school diploma and professional awards hung proudly above a bookshelf packed full of thick medical textbooks and antique decorative doctor’s instruments. As I looked closer, I saw that the med school textbooks were dated from the early 1980s and looked like they hadn’t been opened (or dusted) in years. The last of his professional awards was received last century, as the fading ink read 1996 on the yellowing paper. It made me wonder if this doctor was keeping his skills current or if he’s just been going through the motions since the mid- ’90s. Are those antique doctor’s instruments just for decoration or does he still use those?!? I grew more doubtful as my eyes scanned the dinghy artifacts. I realized that even though he had all these symbols of learning, there was no way for me to see what he really knows. I’m just expected to see those items and trust that he learned everything he needed to know to keep me healthy.

Your resume (or your school transcript) isn’t too different from that doctor’s office– they tell others where you got your experience and when, but they don’t show what you really learned from those experiences. This is why many educators are recommending students compile ePortfolios, a culmination of their best work over the course of their educational careers. With an ePortfolio, people can actually look at the very best work you have produced and they can see the quality of thinking for themselves. You can use an ePortfolio to continually develop your ideas over time and engage others in a public discussion about the things you are interested in learning. As you may imagine, this is also good practice for professionals who have left formal education, so they can demonstrate that their understanding of their field is current, complete, and sophisticated. If that doctor had a blog discussing new developments in medicine or showing off the articles he reads, it would have gone a long way towards reassuring me that I would be in good hands under his care.

A personal blog is the perfect tool for an ePortfolio because it allows you to easily post almost any kind of work that you do– writing, videos, audio, photos and more. This gives your readers a clear picture of what you’re working on so they can see for themselves the quality of your work. Blogs also feature tools to help you organize your writing by categories, tags, and pages so your readers can easily find content that interests them. A blog can also be a place where your other outputs– like twitter tweets, bookmarks, RSS feeds, and flickr photos– all come together to demonstrate your many learning pursuits.

Make it Easy

Many of the tools we use for getting new information allow us to create a digital “trail” for others to follow without any extra effort. Google Reader, which we discussed last time, has a Share button that allows you to publish interesting posts to your followers as you read. Articles you share go up onto a special public page (here’s mine) which has its own RSS feed so you can feed your shared links into other tools. MY Google Reader list feeds into a widget on the right hand side of TedCurran.net so people can see what I’ve been reading. I also use the sidebar of my blog to show off my most recent twitter tweet, my Diigo bookmark collection, and the podcasts I listen to. I share these because the people who appreciate my writing would probably also appreciate the other articles I’ve been reading on similar subjects. By reading through and picking out the “best of the best” among my inputs, I’m sharing my perspective on what’s important with my readers without actually doing all that writing and reviewing myself. This helps me provide a valuable experience to my readers in a way that doesn’t add extra work for me.

I recommend this method to small business owners working in competitive fields (I do a little web design on the side) so they can demonstrate their expertise to potential clients. It also becomes a tool to educate your ongoing clients around issues that will help them get more out of the services you provide.

I did this as a classroom teacher too– I used a tool called Google Notebook (RIP) to clip little snippets of information that I would find as I was researching new lessons or units for my students. Sometimes I would clip articles expressly for them to read as assignments, but other times I would just add interesting readings to the feed for them to explore independently. Often they were readings that had informed my understanding of our projects but that I couldn’t find a way to work into the flow of our daily assignments. (If you’re interested in this sort of workflow, I’d recommend using Diigo for Educators nowadays).

Using these little tricks means that showing what you know does not require doing a lot of extra work– if you can’t find the time to write periodic blog posts, think about just sharing a steady stream of interesting articles with your chosen audience. Next, I’ll talk about another tool that helps make showing what you know easy.

Shareaholic

Shareaholic is a great little browser plugin for most major browsers that makes it easy to share webpages on almost any social network you can think of. If you’re like me you have different types of friends on each social network– professional contacts on LinkedIn, close friends and family on Facebook, work colleagues on Diigo, and those people who still only do email– and Shareaholic makes it easy to share content on whichever “output” works for you. This way, you can create several different “channels” of information that can be customized to the different audiences and social networks that make up your Personal Learning Network.

shareaholic

Engaging with Your Networks

One mistake that many people make with social media is that they try to use it as  a megaphone– to post in as many different social networks as possible in the hopes of reaching more people.  Tools like Shareaholic and another favorite, Ping.fm, make it easy to blast your tweets into every social network at the same time, but I was surprised to find that this doesn’t translate into increased traffic. The same way you shouldn’t trust SEO gurus who will promise to get you to the top of Google searches in a week, you simply can’t game social networks to promote your content. The Internet has a way of rewarding content that is actually relevant and useful to people, so you have to put in the work to find out how your ideas fit into the larger conversation.
The best way to get people to pay attention to your blog is to genuinely engage in conversations with other people. Most of the traffic that comes into my blog now comes from comments I’ve made on other people’s posts– posts that are on the same topic as mine, where my blog can serve as part of the larger conversation on this topic. Finding like-minded people who are writing and tweeting about your topics of interest and asking questions, sharing ideas, and moving ideas forward is at the heart of building your Personal Learning Network. It has the added benefit of driving web traffic towards your work– traffic that you can then figure out how to turn into dollars and cents.

Please Share Back Your Experiences!

I have been very heartened and grateful at the way Part I of this post has spread across Twitter and the personal blogs of many of my own heroes on this subject. I’d love to hear your reactions as you try these techniques or compare my ideas to your own ways of managing your PLN. Feel free to use the comments below (which can cross-post to your favorite social networks as well).

f.lux– A Plugin To Save Your Eyes

A couple months ago I added a free, open source plugin to my Mac called f.lux that promises to relieve eye strain and insomnia caused by blue screen glare. It adjusts my screen’s color temperature based on the time of day to reproduce more natural lighting conditions.

It turns the whites on my screen to more of a peachy glow as I geek into the night. I haven’t noticed any performance hit on my MacBook Pro so I’m just going to tell myself that I’m adding years of good vision by using this app. Also works on Windows and Linux.
