I have taught on zoom. Even with highly-motivated, well-prepared college students who wanted to be there, leading discussion sessions was hard. Keeping the conversation moving took so much more energy than in the classroom, and those great "aha!" moments, when things click for all the students together and the conversation takes off, just never seemed to happen. Those are the moments when the most learning happens the fastest. Yea, we got through the material, but the joy was gone...and so was a good chunk of the learning. The idea of trying to do that with literal twelve year olds just feels absolutely ridiculous.

Preserving Virtual Worlds 122

Posted by Soulskill from the how-will-they-play-starcon-2-in-2150 dept.
The Opposable Thumbs blog has an interview with Jerome McDonough of the University of Illinois, who is involved with the Preserving Virtual Worlds project. The goal of the project is to recognize video games as cultural artifacts and to make sure they're accessible by future generations. Here McDonough talks about some of the technical difficulties in doing so: "Take, for example, Star Raiders on the Atari 2600. If you're going to preserve this, you've got a couple of problems. The first is that it is on a cartridge that is designed to work on a particular system that is no longer manufactured. And as long as you've got a hardware dependency there, you're really not going to be able to preserve this material very long. What we have been looking at is how feasible is it for things that fundamentally all have some level of hardware dependency there — even Doom has dependencies on DLLs with an operating system, and on particular chipsets and architectures for playing. How do you take that and turn it into something that isn't as dependent on a particular physical piece of hardware. And to do that, you need information about that platform. You need technical specifications that allow you to basically reproduce a virtualization that may enable you to run the software in its original form in the future. So what we're trying to do is preserve not only the games, but preserve the knowledge that you would need to create a virtualization platform to play the game."

New Estimates Say Earth's Oceans Smaller Than Once Believed 263

Posted by timothy from the deeper-than-my-love-for-you dept.
Velcroman1 writes with this snippet from Fox News: "Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big? As long ago as 1888, John Murray dangled lead weights from a rope off a ship to calculate the ocean's volume — the product of area and mean ocean depth. Using satellite data, researchers from the Woods Hole Oceanographic Institute set out to more accurately answer that question — and found out that it's 320 million cubic miles. And despite miles-deep abysses like the Mariana Trench, the ocean's mean depth is just 2.29 miles, thanks to the varied and bumpy ocean floor."

The Parking Meter Turns 75 Today 126

Posted by samzenpus from the thanks-a@#hole dept.
nj_peeps writes "75 years ago Carl Magee filed a patent application for what would become one of the most hated inventions in history: the parking meter. From the article: 'Magee's brainwave was to install a device that had a coin acceptor and a dial to engage a timing mechanism. A visible pointer and flag indicated the expiration of the paid period, meaning you either had to move, put in more money, or face the wrath of the local constabulary. The design continued largely unchanged for more than 40 years.'"

Cassandra and Voldemort Benchmarked 45

Posted by timothy from the rifling-the-file-cabinet dept.
kreide33 writes "Key/Value storage systems are gaining in popularity, much because of features such as easy scalability and automatic replication. However, there are several to choose from and performance is an important deciding factor. This article compares the performance of two of the most well-known projects, Cassandra and Voldemort, using several different mixes of access types, and compares both throughput and latency."

TSA Worker Jailed In Body Scan Rage Incident 352

Posted by samzenpus from the checking-out-your-package dept.
A TSA worker in Miami was arrested for aggravated battery after he attacked a co-worker for making fun of the size of his genitals. Rolando Negrin walked through one of the new body scanners during a recent training session and a supervisor started making fun of his manhood. From the article: "According to the police report, Negrin confronted one of his co-workers in an employee parking lot, where he hit him with a police baton on the arm and back."

Beaver Dam Visible From Space 286

ygslash writes "The Hoover Dam no longer holds the title of the world's widest dam. Satellite photos of northern Alberta, Canada, show that several families of beavers have apparently joined forces to build a dam 850 meters wide, more than twice as wide as the Hoover Dam."

MIT Unveils First Solar Cells Printed On Paper 125

Posted by timothy from the let's-give-them-some-post-unveiing-privacy dept.
lucidkoan writes "MIT researchers recently unveiled the world's first thin-film solar cell printed on a sheet of paper. The panel was created using a process similar to that of an inkjet printer, producing semiconductor-coated paper imbued with carbon-based dyes that give the cells an efficiency of 1.5 to 2 percent. That's not incredibly efficient, but the convenience factor makes up for it. And in the future, researchers hope that the same process used in the paper solar cells could be used to print cells on metal foil or even plastic. If they're able to gear efficiencies up to scale, the development could revolutionize the production and installation of solar panels."
