Christmas Tree-gonometry

Christmas TreegonometryGizmag let us know how to get the perfect Christmas tree. University of Sheffield Maths society students Nicole Wrightman and Alex Craig have developed a formula for the perfect Christmas tree. They developed that formula in response to a challenge by U.K. department store Debenhams.

The formula uses the height of a Christmas tree to get that catalog-perfect look. The height tells you how to decorate the tree. The formula calculates the ideal number of baubles, length of tinsel, and length of lights. It even calculates the height of the star, fairy, or angel sitting atop the tree required to get the catalog-perfect look. “The formulas took us about two hours to complete,” Ms. Wrightmas said. “We hope the formulas will play a part in making Christmas that little bit easier for everyone.”

The “treegonometric” formulas are:

Perfect Chrismtas Tree

For example, a 6 foot tall (180 cm) Christmas tree needs the following decorations. It needs 37 baubles, around 309 feet (919 cm) of tinsel, and 18.5 feet (565 cm) of lights.  The star or angel must be 6in (18cm) to achieve the perfect look.

For those without a calculator at hand, an online calculator can be found here.

Sonya Gillam, Debenhams’ Christmas decorations buyer said, “We wanted to create a way for our customers to save time and money while still achieving the perfect looking tree, no matter what the size.

How To Bake Christmas Cookies

How To Bake Christmas CookiesGerman automaker Mercedes-Benz has created the most expensive way to bake Christmas cookies. PSFK spotted this ad that uses the MB SLS AMG GT3 supercar rather than a kitchen appliance to bake holiday treats while going over the river and through the woods to grandma’s house.

At $500,000 the Mercedes SLS AMG GT3 is probably the most expensive and coolest oven to bake Christmas cookies.

I Survived the End of the World

According to some ‘experts’, the Mayans predicted that the end of the world is on or after 12/21/2012. Well if you are reading this the world did not end.

end of the world,

So who were the Mayans? According to this article, the Mayan civilization flourished in what is now the modern-day Central America region which includes parts of Mexico, Guatemala, Belize, El Salvador, and Honduras. The period of their society lasted from roughly 1800 BC to 800 AD. Why the Maya civilization disappeared is subject to debate among scholars, and includes theories such as a multi-year drought, peasant revolt, disease, and possible overpopulation.

The Mayans left many contributions to the world including their hieroglyphic language, Mayan architecture which includes the famous stepped pyramids, and one of their most famous contributions, the Maya Long Count Calendar.

What is the Mayan Calendar? The Mayan Calendar is actually a collection of several calendars the Mayans used to synchronize events for farming, politics, and astrological events such as the Venus cycle. All of these calendars ranged from as short as 13 days up to 584 days. The Mayans designed their calendar (we believe) to be liner in nature so that it could be extended to any date in the future until eternity. BUT IT STOPS! December 21, 2012 is the last possible day of the current Mayan Calendar.

Did they expect a new, updated calendar would be created?

Are you supposed to re-cycle the existing calendar as the Mayan culture was steeped in the recognition of death and rebirth?

What did they intend when they made the current calendar?

Detroit Leader in Identity Fraud Rings

Detroit Leader in Identity Fraud RingsMotown has a new not-so-good title. ID AnalyticsID:A Labs has identified the metro Detroit area as one of the top areas for identity fraud. According to their research, there are over 10,000 identity fraud rings in the U.S., and the three-digit ZIP codes with the most fraud rings are around Washington DC; Tampa, FL.; Greenville, MS; Macon, GA; Detroit; and Montgomery, AL.

DetroitThe credit rating bureau says an identity fraud ring is a group of people actively collaborating to commit identity fraud. Help Net Security reports this study is the first to investigate the interconnections of identity manipulators and fraudsters to identify rings of criminals working in collaboration.

While many of these fraud rings involve two or more career criminals, surprisingly, others are family members or groups of friends. The article says that ring members operate by either stealing victims’ identities or improperly sharing and manipulating personal identifying information such as dates-of-birth (DOB) and Social Security numbers (SSNs) on applications for credit and services.

Other findings of the study include:

  • States with the highest numbers of fraud rings include Alabama, the Carolinas, Delaware, Georgia, Mississippi, and Texas.
  • While many fraud rings occur in cities, a surprisingly high number were also found in rural areas of the country.
  • A large number of families are working together in fraud rings, even using each other’s SSNs and DOBs. However, rings made up of friends are more common, with the majority of fraud rings made up of members with different last names.

“In this latest research, we have taken a broader approach, looking at connections among bad people rather than studying individual activity,” Dr. Stephen Coggeshall, chief technology officer of ID Analytics said in the post. “This information enables us to build new variables into our fraud models so we can help our customers to make better decisions and improve protection for consumers.

ID:A Labs looked at about 1.7 billion identity risk events including applications for credit cards, wireless phones, payday loans, utilities, and other financial services credit products. It also examined changes in personal identifying information among accounts such as changes in name, address, DOB, and SSN to identity over 10,000 fraud rings in the United States.

VC’s Take on Ed Tech

VC's Take on Ed Tech  at GigaOM reports on an open online course on entrepreneurship in education called Ed Startup 101. During the course, Fred Wilson, a managing partner at Union Square Ventures, gave a little insight into how venture capitalists view opportunities in education technology. Union Square Ventures has invested in education social network Edmodo, Skillshare, Codecademy, and Duolingo.

skip over institutional buyers to target teachers and studentsVC Wilson said that education’s, notorious reputation for bureaucracy and long sales cycles have traditionally turned off VC’s (full video available here). But as startups have attempted new models that skip over institutional buyers to target teachers and students, investors have steadily warmed to the sector, including K-12 education. The blog cites data from GSV Advisors, a Chicago-based investment firm that specializes in education, which says that transactions in K-12 education climbed from just $13 million in 2005 to $389 million in 2011. Funding has been so strong that some have already started asking the inevitable question about whether an ed tech bubble is brewing.

Takeaways from the video

VC's Take on Ed TechConsumer tech offers plenty of models for freemium ed tech startups –The venture capitalist gave several examples in which consumer startups with a free service eventually found a path to profitability after years of venture backing, including Dropbox and Twitter. In those examples, he said, venture capital played a key role in helping them reach the scale that would make a freemium model work.  As the ed tech market expands, he expects models of all kinds – from those supported by advertising to those with enterprise licensing models – to emerge. Both Dropbox and Twitter are problematic to an enterprise network.

  • Someone, PLEASE give me a long-term educational reason to give students on-network access to Twitter that outweighs the distraction and cheating factors.
  • Dropbox is a potential data theft tool if allowed. We have seen 600 – 800 Mb of Dropbox space on user shares, then they complain when they can’t save their work to the network. Dropbox’s network behavior is annoying. Dropbox wants to check in with the mother-ship thousands of times a day. On our network, we block file sharing with the content filter. When a user installs a Dropbox client on their workstation (don’t get me going about local admins) we have seen 60,000 attempts to connect to the Dropbox mother-ship over the course of a week. Dropbox could improve their product by throttling their checking in – the longer it doesn’t connect throttle down their phone homes.

Sell to the learner first, not the institution

Work-aroundMr. Wilson says that ed tech firms should bypass traditional education sales channels. “We should compete with the existing education system as opposed to sell to it,” Wilson said. He thinks that entrepreneurs can make faster progress by bringing their tools straight to the learners and the teachers providing instruction. That’s the way Edmodo has gained its strong traction and the approach Codecademy has taken with its after-school program targeting students in schools without computer science instruction. As students and teachers adopt new platforms, Wilson said, the institutions will come around.

Gee I don’t know, sell to the end-user and then force the entire enterprise to change to accommodate a new toy, how very Apple of him. But VC’s don’t have to do the work. Maybe if he had to make AppleTV work on a network or get iMac‘s to regularly log in to Active Directory.

Vendor exclusivity is a bad thing

Vendor lock-inAs more companies turn their attention to online learning and digital education, Wilson said universities shouldn’t standardize with just one vendor but support the range of tools that faculty members choose. Exclusivity, he said, makes vendors “fat and happy” and less incentivized to innovate.  “I don’t think there’s any benefit anyone would get by standardizing on one platform,” he said.

I agree with him here, the perfect example is Blackboard. They don’t seem to want to make our life easier. The restoration process is stupid. Bring on Moodle.

Other areas of opportunity in ed tech

The VC says that his firm also thinks there are ed tech opportunities include:

  • Credentialing (Grades) Now that plenty of platforms offer courses and instruction, the next step is figuring out whether students are actually mastering the skills and knowledge that they’re setting out to learn.
  • He also said he thinks there are opportunities in peer-to-peer platforms, which leverage online communities to reduce the cost of creating curriculum and learning content,
  • Vertically focused startups, such as those similar to Codecademy and Duolingo.

rb-

freemiumIt’s not only my opinion that the freemium model is a bait and switch scam. It sucks users into a product and then does a switch at some time in the future to a pay model. But that is a VC’s take on Ed Tech, what is yours?
