Simulation and Modeling in Technology Education (SMTE) Project

This is a temp demo video for the Survival Master game for STEM learning - Knowledge and Skills Builder 2B - Surface Area Heat Flow Challenge level. In this single player platformer level, the learner uses knowledge about heat flow for shapes based upon surface area - to negotiate unlocking a series of elevators and catapulting across a pit of solvent hazard to complete the level and earn energy bonus points and achievements.

Simulation and Modeling in Technology Education (SMTE) Project

This is an overview of the design of the Survival Master multiplayer game level, which is a small team survival shelter engineering challenge that incorporates the STEM skills developed in the four single player "knowledge and skills builder" levels for shape volume and surface area, conductive heat flow, insulators, and structural stability and integrity.

WikiLeaks and DNS

[Notes: Click images for higher resolution. This post was originally published on 12/3/10, then edited and repost-ed on 12/7/10.]

We all probably have some idea and opinion (depending on particular sources) about what is going on with WikiLeaks and the exposing of hundreds of thousands of classified US state documents. I'll keep my personal opinions private here. Technically it has been interesting to watch the cat and mouse game and I thought it would be good to diagram how DNS works.

EveryDNS.net, a U.S. DNS provider pulled WikiLeaks from it's database, claiming constant denial of service took the controversial site offline earlier today, claiming that the constant hacking attacks were so powerful that they were damaging its other customers.

What's DNS and why is it so important? I always describe DNS as basically an internet telephone book - it keeps track of site names (URLs) and the IP addresses of the servers hosting those sites. It is something that is not required to access websites but makes it a lot easier because users only have to remember site names and don't have to remember long IP addresses. You get access to DNS with a web connection from your provider. There are also some good alternative DNS providers you can access as long as you have an internet connection. Here's a diagram I made up showing how it works.
Is DNS required to access websites? No. You can still get to a site by typing in the IP address of the site.

I've got an earlier post on DNS linked here that you may also find interesting.

FCC Chairman - Net Neutrality Proposed Rules

I've written here in the past about Net Neutrality and the issues. Yesterday, FCC Chairman Julius Genachowski announced a set of proposed rules to protect the open Internet. Here's a summary of Genachowski's announcement with pieces taken from a post by Nick Farrell:

• Genachowski will present the principle that broadband companies shouldn't block or degrade rival web content, services or applications to a vote that will be held on 21 December.
• The compromise rules in theory mean that US Internet users can use peer-to-peer software and see whatever websites they like and use any equipment they like on their cable or DSL connections.
• Carriers and ISPs will be barred from slowing down or blocking content from competitors. The ISPs will also have to be transparent about how they manage congestion on their networks to ensure that anti-competitive behavior isn't being disguised.

Sounds good so far but is it enough? Carriers will still be allowed to create paid fast lanes on the net and the FCC is not reclassifying the Internet as a "telecommunications service", which would have given the FCC clear authority to enforce its rules.

According to Farrrell, Genachowski has the support of Cisco CEO John Chambers, AT&T senior executive VP Jim Ciccono, and Comcast EVP David Cohen. The Communication Workers of America is also in support with a petition you can sign here. Not everyone thinks it goes far enough though. Sascha Meinrath, director of the New America Foundation's Open Technology Initiative has a post over at Wired. Here's a quote from Meinrath's piece:

Without fundamental changes to the current order, the Chairman’s proposal will be a great victory for the largest telecom corporations and a sound defeat for those working to support innovation and the economic vibrancy that an open Internet facilitates. The New America Foundation is hopeful that the Chairman’s office and Commissioners that support open Internet rules will develop a final order that uphold the FCC’s responsibility to protect consumers and Internet freedom.

In order to take effect, the proposal must be approved by a majority of the five FCC commissioners . Here's how Wireless Week breaks down that vote if it were to happen today.

• There’s no way Genachowski will vote against a proposal he himself introduced and has fought so hard for. He's a YES.
• Michael Copps issued the most carefully-worded statement of the bunch, but so far he’s been a big proponent of Genachowski’s net neutrality push and it’s unlikely he’ll back out now. Also a YES.
• Mignon Clyburn seemed to be in favor of the plan, saying “clear rules of road are absolutely necessary.” Another YES.
• Meredith Baker and Robert McDowell came out against the idea in comments filed today. That is two NOs.

Right now it looks like it would pass 3-2. We'll see what happens on December 21.
