Bitwarden

Consider this a general admonition to learn to use a password manager and a specific comment on such manager – Bitwarden. I have an account with a different manager (LastPass), but Bitwarden is available at no cost and I wanted to explore for myself just how easy it was to use. This investigation came about after online discussion I had with an ex-LastPass user who objected to a change LastPass had made in its pricing model. LastPass still has a free version, but this version is only available for one category of device (phone, laptop, computer) and this makes it impractical for most of us who use multiple types of devices to stick with the free version. Bitwarden has a personal paid version ($10 a year) that offers some premium features, but the free version seems perfectly acceptable to me. Ten dollars is significantly less than the amount I pay for LastPass so some may consider exporting their collection of passwords and migrating to Bitwarden.

I will not attempt to provide a complete tutorial here because Bitwarden offers some great video tutorials and why duplicate their work.

Bitwarden functions as an app or a browser based extension. You need a general account (the online system that allows you to synch multiple devices) and then whatever number of apps and browser extensions you find necessary. I rely on browser extensions.

The key to understanding password managers is to understand that you want lengthy and complex passwords and you want a unique password of this type for each account you access. With a passward manager you need to learn (remember or store in a secret place) one such password and then you use the manager to remember the other complex passwords for you.

The general storage site for such passwords looks like this. This where you add items to your collection. You can launch accounts from here or the manager will launch items automatically if the manager is active when you go to a site that demands a password.

One nice feature of a password manager is the option of you asking it to generate a complex password for you (see the icon enclosed in the red box below). You likely already have accounts with existing passwords so one solution is to create the new item in the password manager, connect to the existing account with the old password, and then changing the password of that account to match the password created in the password manager. Finally save and then test the new item from the password manager. Yes, there may seem an element of risk in this process, but I assume you know the old password and have the new password (unsaved) in the manager and temporarily saved if you copy and paste it to create the new password on the site you want to update.

Start slowly if you feel uncertain of the process. Use one site with an existing password, upgrade the password in the manager, and then see if you the site works with the new password and not the old.

Discovery with the Amazon Show

We often end up giving ourselves technology Christmas presents. This year it was the 15 inch Amazon Show. At $250 or so, this is a very impressive device. The quality of images and video is great and of course, you can ask questions to search.

The Show runs the Amazon Silk browser. It is easy to enter text searches from the screen and use Silk on the Show pretty much like you would use Chrome on an iPad.

As an example, I thought I would examine some of the tutorials I had created on YouTube. I tried searching for Mark Grabe and found something I had never seen before. In 2014, I did an interview on a local television channel and searching my name brought up this video (for anyone interested in watching me talk about cyberbullying here you go). I had no idea this interview had been preserved.

For the classroom – this device would be an interesting addition to classrooms. It is large enough for a group of students to view and it is inexpensive.

BTW – I had forgotten about the app I described in the interview. Here is a link to StopIt.

Both Sides Now

The Polarization Lab at Duke University has been investigating how social media exposure increases or decreases existing political extremism. I review some of the tools they make available and some of the research they have conducted in an earlier post.

One of their more interesting experiments involves the use of bots they have created to forward the input from moderate liberals and conservatives. They propose that exposure to extremists of either orientation leads to greater polarization, but exposure to moderate positions taken by those with a different position than your own may lead to a lessening of polarization.

I have been following both Twitter bots for several months now. You can participate as well. If you don’t want to participate, you call always search for one of the bots just to see how the feeds from moderates of both perspectives differ.

@Polly4Conserv – for liberals to learn about moderate conservatives

@Polly4Liberals – for conservatives to learn about moderate conservatives

Educators looking for an interesting project might ask students to come up with a system for studying political orientation and apply this system to the two different sets of tweets.

Both Sides Now (with apologies to Joni Mitchell). I guess Phil Collins Both Sides of the Story also works.

Don’t repeat your passwords

Anyone online is only as secure as the quality of their passwords and even with a good password they can be vulnerable. I pay for LastPass to protect access to the multiple sites I use. I was alarmed to see reports that LastPass users may be vulnerable. The following explanation offers me some relief and I hope the explanation is accurate. Don’t use a password for a password manager you have ever used elsewhere.

LastPass breaches appear due to credential stuffing.

‘A credential stuffing attack is when hackers take username and password combinations leaked through data breaches and attempt to use them at other online services, hoping that some users reused credentials across different sites.”

Sal Kahn on mastery learning

Most educators are familiar with the Kahn Academy, but may not appreciate the overall structure of the Academy for student learning. There is a big difference between using the resources provided by Kahn to address a specific need and the use of the curriculum of the Academy and the focus on mastery learning.

Here is a short post from EdSurge that contains an audio interview with Sal Kahn. The focus on this post is mastery learning. Mastery learning has been a personal focus since the late 1970s. As I became interested in technology, I was convinced that technology provided opportunities to make mastery concepts practical. Here is my take on mastery learning (more about the origins and components) and how it relates to the model in Kahn’s approach.

Tools and tactics tutorials

As a class project, I have students in my graduate instructional design class generate tutorials for educational relevant apps or online services. These tutorials may offer useful information to K12 educators interesting in exploring new tools for their classrooms.
