There is a new technique that allows an attacker to unlock a Windows machine or login without a password. This vulnerability also affects OS X. Right now the hack currently requires a Linux laptop, but it could conceivably make its way to modified iPods.
To protect yourself you’ll need to disable Firewire in your PC BIOS, or on the Mac you will need to set the Open Firmware password.
When we first started recommending Firefox, one of the first features that the students found was the ability to change themes. Unfortunately, changing a theme is a pretty heavy weight process, requiring a restart of Firefox. Mozilla Labs has been working on a different theming process, Personas, which doesn’t require a restart:
Features
- You can select a Persona from the dynamic menus and see results instantly without having to discover, select, download or install a separate bit of software or code.
- Personas can be added, removed or updated by their designers at any time, without requiring a software update.
One caveat, the theme can be changed by the designer at anytime, which means there is a chance that something inappropriate may be viewed.
The Our Stories™ project helps people share the stories of their lives, no matter where they live or how their stories unfold. We’re providing resources to create and share personal stories from all over the world, starting with children in developing countries who are using One Laptop per Child (OLPC) computers or those who are working with UNICEF radio producers to record and share interviews. Children are asked to record the stories of elders, family members, and friends.
Take a $40 Wiimote, an infrared emitting pen and you have the makings of an interactive whiteboard (No Nintendo Wii required). Johnny Chung Lee has been experimenting with the Wiimote. The Wiimote connects to the computer over bluetooth, and inside it is an infrared camera that can track up to 4 LED sources.
Check out the video of it in action:
Now to find a source for some infrared penlights or make my own and try this out. With projectors costing less than $800-$900 this would be a very inexpensive way to bring interactive whiteboard technologies into the classroom.
Reading over at Slashdot.org and the original article at ScienceDaily it appears that film enjoyment can be contagious:
Over the course of the film, movie-watchers influence one another and gradually synchronize their emotional responses. This mutual mimicry also affects each participant’s evaluation of the overall experience — the more in sync we are with the people around us, the more we like the movie.
Can this research be applied to the classroom? We’ve all taught at least one lesson where it seems like everything clicked. The students were engaged, on task, and excited. Even the most prepared teacher can have a lesson go south, but it appears that a lesson might be saved by “groupthink”. By slowly bringing the class on task, it can cause a snowball effect, not only increasing the enjoyment of the students but also increasing their retention.
I’m reminded of this post by Miguel Guhlin
In my early years of working with adult learners, I facilitated a workshop that was everyone’s nightmare class–a cafeteria technology inservice. In the morning, provide inspiring words about using technology. In the afternoon, hands-on tutorial. The morning went well since we had cooperative grouping, activities, etc. The afternoon was focused on how-to, but I had some physical education coaches that whipped out newspapers. I was supremely irritated and felt powerless. It was my first solo workshop for the Education Service Center, and I wasn’t sure what to do…if I’d been working as a school district facilitator, I know exactly what I would have done–I’d asked them to leave. Instead, I put up with them.
Although a teacher can’t “fire” their students, a teacher needs to be aware of the negative influence those off-task students are having on the rest of the class.
From PayScale Meeting Miser - Meeting Cost:
Are your meetings worth every penny? Find out with the new Meeting Miser. Just enter the attendees and start the timer. This handy gadget knows that time is money and will calculate exactly how much you’re spending … or wasting.
The site uses actual salary info for your area to calculate the cost per meeting. I tried it with a typical scenario, 3 elementary teachers and a principal meeting. The cost came to $1.41 a minute, or $84.60 an hour. An administrator meeting with 4 principals and the superintendent jumps up to $2.84 a minute ($170.40 an hour!). Might be something to bring up the next time you are sitting in a meeting that isn’t accomplishing anything.
