Tools for Critical Thinking and Skepticism


Relevant to our discussion on Tuesday night, an online article by Alan Henry.

How to Determine If A Controversial Statement Is Scientifically True
(introductory excerpt)
Every day, we're confronted with claims that others present as fact. Some are easily debunked, some are clearly true, and some are particularly difficult to get to the bottom of. So how do you determine if a controversial statement is scientifically true? It can be tricky, but it's not too difficult to get to the truth.
Every internet user has developed a healthy dose of skepticism that keeps us from being duped by things that don't pass the smell test, but it's not enough to just think something might not be true. What if you think the statement might be true and you want to learn more? What if you want to respond to the assertion or engage in conversation but you don't know enough to do so?

Assignments for Tuesday

I've neglected you all this week.  Other than reviewing three new technologies*, the only other assignment was to continue developing your technology-integrated lesson ideas, maybe using the template I offered: goo.gl/hBJnY

* Remember you are not restricted to the Top 100 slideshare.  Consider also CNET, the Department of Ed Resources, or any other source you find.  (Free is good!)

Touring the labs at the Arlington Career Center (Arlington Public Schools).

Perfect Passwords

I'm sharing  Alexandra Petri's funny blog post on passwords, which will be a topic of discussion on Tuesday night.

JAE

========================

After the Linkedin hack, how to pick the most secure password of all time


Paul Sakuma - Associated Press)



The perfectly secure, perfectly memorable password is absolutely pure and rarer than the unicorn. It is like the Holy Grail, the Fountain of Youth, the philosopher’s stone, or a model that will get users on the Internet to pay for curated content. That is to say, no one has ever found it, and some doubt whether it exists at all.
Recently Linkedin.com announced that something like 6.5 million passwords had been hacked. If you have a Linkedin account, you had better act quickly and come up with something secure before your identity gets stolen! Or you could just quit Linkedin. That might be easier. Coming up with a secure password is harder than it sounds. And it sounds hard!

Tips abound, but they are even worse than the problem.

The usual rules for picking a password go something like this: Combine a whole bunch of letters and numbers in the precise order you are least likely to remember. This forces you to write them down on a sticky note somewhere visible in your office, defeating the point entirely. (On the bright side, this makes it easier for the investigators to find out about your extramarital affair if you are ever murdered.)
As XKCD points out, this situation is absurd.

I spent the past several months in prayer and meditation on the subject, and finally inspiration struck. Here are some of the Internet’s top tips for secure passwords — and what to do about them.

    1. Use a combination of alphanumeric characters and symbols that does not depend on actual words.
A Web site billing itself as “Perfect Passwords” suggested this one: BD052EA025643096595CD1A217658B10374242DC59DB397D9088C24DAEAF9059.
Perfect!
 
 2. Use the first letters of the lyrics of a song that you like. For instance, “Billie Jean is not my lover” becomes “bjinml.”

This assumes a great deal — for instance, that you actually remember the lyrics of the songs you like. I love “Smells Like Teen Spirit,” but for years I thought the lyrics were “Awastuuuka, keratin augh, amakneeler, zindahealer! YAEERGH.” And I am still not convinced that they aren’t.

I also like that new Rihanna song, but lyrically it has little to offer. Here is the main line of the chorus in its entirety: “cake cake cake cake cake cake cake cake cake cake cake cake cake cake cake” (“ccccccccccccccc”).

And if your favorite song is “La Bamba,” you might as well turn in the keys now.

3. Use phrases that speak to you but no one else, like “My ’94 Hyundai Excel Is Blue.”
Look, if you are still driving a ’94 Hyundai Excel, I doubt anyone wants to steal your identity.

4. Mix two memorable words together. They suggest dcoagt.
This is easier if you are dyslexic, I think. I tried this and got whorewantstoseeyou, combining the two familiar words “woe” and “hr wants to see you,” and now HR wants to see me.

5. Don’t use a phrase that is popular or common.
So a good, secure password might be, “That Michael Buble is so edgy” or “I have few qualms about the quality of Fox reporting” or “The Washington Redskins are uniquely competent.”

6. Use your anniversary as a password. “That way, you’ll never forget either!” the people who write this sort of advice say, a little too optimistically, I think.
Who are these people, anyway? You have the sense, reading their advice, that they have beautiful, organized homes and children whose names are good, sturdy, alphanumeric blends, and they seal all their leftovers in carefully labeled plastic containers. They amuse themselves by reciting long strings of numbers and song lyrics to their spouses while sitting in their blue Hyundai Excels. We are not like them.
For most real people, using your anniversary as a password guarantees that you will forget both. “Honey,” you will be forced to say, “I can’t seem to get into our bank accounts.”

“What’s the password?”

“Our anniversary.”

“So what’s the problem?”

“Well,” you say. “I think perhaps a malicious time traveler changed the date in my timeline, and I was wondering if you would tell me if it is the same day that I remember?”

This will be the best you can do under pressure, and it is not enough. You’ll wind up on the street without access to funds as someone cries and flings Tupperware containers of leftovers at your head.

7. Use something memorable, like a historical date.
This would be good advice if I had not been in conversations where people asked, with no irony whatsoever, “When was the Compromise of 1850?”

The memorable things are never the things you actually remember. Your anniversary? Your child’s birthday? Of course not. You are too busy remembering all the lyrics to a song about recycling that you were forced to memorize as a small child, or the fact that Michael Fassbender and Zoe Kravitz briefly dated, or anything negative anyone has ever said about you.

And the sad, specific sentences aren’t even unique. At least one other person, Buzzfeed found, has “foreveralone” as a password.

If there is one thing I have learned in all this research, it is that there are memorable passwords and secure passwords, and never the twain shall meet. No, the only thing to do is try to get the sympathy of the hacker. My password is “Pleasesirormadammyidentityisworthlessbutitisallihave8.” (They make you put a number in.)

TinEye Reverse Image Search


As a former field biologist, friends often ask if I recognize this or that critter.  The one pictured here was new to me.  But after down;loading the photo or copying the URL, I went to tineye.com and within a minute or two I found the same picture labeled, "Blue Seaslug".  A wikipedia search confirmed it was Glaucus atlanticus.


Location Change - June 12

After reading this - please use the embedded form below acknowledging the change, so I know you're aware!  Click on the map for more details, or directions from your location.

On June 12 we'll meet in an Arlington school building, the Arlington Career Center.  This building is home to many special programs, but also the Governor's STEM Academy in Arlington.  Not only do I want you to see the labs, but I want to give you some experience with a variety of interactive whiteboards.

We may get shuffled around, and we'll begin with a tour of all the special labs and classrooms, but we'll meet initially in Room 114, the Engineering and AutoCAD lab, visible from the front doors.

Parking is free.  The building is connected to the Columbia Pike Branch of the Arlington Public Library, and across from Patrick Henry Elementary, at 816 S. Walter Reed Drive.  If you need any sort of help getting there, indicate that below or in an email to me at Jim.Egenrieder@gmail.com.  I can meet you at a metro stop and drive you if that's helpful.

Try Dropbox

Google Drive (formerly Google Docs), Dropbox, and iCloud have similar functions.  They provide "cloud" storage for your documents so you can access them from work, school, home, libraries or cybercafe's, and other Internet-connected computers.

Google Drive has the advantage of Google searches within your documents, but Dropbox allows for a very Windows-friendly integration and interface. Both are free up to a specified level of storage.  I use all three: Drive for collaborations and documents I create; Dropbox for MS Office documents shared with me, or when I need the extra formatting abilities of MS Office; and iCloud for iPad / iPod files and syncing those Apple products with iTunes.

Use this link for Dropbox:  http://db.tt/EHDhJJo
