Tweaking algorithm: Google gives you a small glimpse behind the scenes

One of the most common complaints of critics (and competitors) have against Google is a company — despite its numerous outdoor products and initiatives is very secretive about the countless algorithms that power their Crown jewels, a Google search. In other words search is a black box. Google's argument was that it should be this way — if he told everyone exactly how the algorithm works, it would be much simpler games and search results will suffer.

In any case, there are a lot of mystery surrounding search, which is why the video is now posted on a blog Google is so interesting: Google gave a quick video guide detailing how its engineers gradually adjust algorithm which — according to the video gets tweaked with more than 500 times per year.

Video is only four minutes and worth watching in its entirely, but here's a quick rundown on how changes to search goes live:

First Google engineers define the complex motivations of sites, which don't work as well as Google would like them to later engineers were trying to identify the different signals (Google doesn't really get into what these signals suggest) that can be used to more effectively respond to this request. these new results are then evaluated by a qualified employee that is not an employee of Google. Further results are pushed live a small number of users. Analyst then assigns objective look at the changes and how it performs in tests.the proposed change were submitted to the Panel, search quality, which approves or rejects it.

The video also turns into a quick joke about what Google calls "full replacement pages. This applies to the times, Google looks at your request, you misspelled words, and then presents the results for the correct spelling, rather than simply offering proper spelling and display results with errors. To test this, Google looked at how many times users clicked on a link to clear the results of their initial request (which, according to Google was a typo), Google decided that until the escape hatch just pressed 1 in 50 times, and good changes. And passed the test.

Kickstarter project gives students plays Mario theme with plasma

This cool Kickstarter allows you to build a working, using the energy of the plasma. This is a bit esoteric, but here's the deal: it's a little Kit that contains everything you need to play music using plasma arc. If it doesn't seem like your idea of a good time, you could read the wrong post.

However, here's how it works: for $ 40 you get the bits that make the arc to vibrate and for $ 80 you get all the bits, including power supply and line transformer. The kit was designed and built in StudentRND group of cool kids in Seattle, which, together with the volunteers, creating wild technical artifacts. It looks like one of their first projects Kickstarter and they are asking $ 2.000 to build multiple packages and support their mission. They have over their minimum, so the project will receive funding, and you can finally play smoke on the water using tiny plasma arc.

Even if you're not down with shooting electricity through the air, StudentRND seems to a large organization and they are clearly having fun with science, something I definitely can get behind.

Google gives Android App inventor of a new home at the MIT Media Lab

In July 2010, Google announced a great educational project called App inventor. Goal? Give programmers a pretty easy way to create their own applications on the Android platform, using the drag-and-drop to add pre-written "pieces" of the code. He has was inspired to study the language scratch, but with an Android.

I ran the platform through its paces soon after its launch, attempting to build some basic applications of my own. It was rough. He was not even close to an easy to use. But it was fun and he's obviously had a lot of potential in a learning environment. A year later, approximately 100 000 persons are using the platform, many of them in the field of education.

Unfortunately last week hack education broke the news that Google is going to shutting down the App inventor, despite the fact that it has received significant traction with the teachers. Apparently this was part of the Google CEO Larry page disk make Google more focused company, which includes assassinations from Google Labs.

Today, Google has some better news: he announced that the inventor of the App is live in the framework of the new MIT mobile learning centre that will be placed in the famous MIT Media Lab and the App inventor creator Hal Abelson and other MIT Professor Eric Klopfer, Mitchel Resnick (both of which were also an important role in the creation of the project).

I really like the inventor of the App is a good introduction to programming, and he also gets students used to programming with mobile devices in mind, which is clearly going to be a big deal, go ahead. And I am glad that MIT agreed to take the torch from Google and save it.

However, I think it's quite funny that Google announced App inventor and then killed him (at least as an internal project) only a year after its launch. There is no way this was a serious burden for the company in terms of resources. And if Google intends to work with one of the universities in the framework of the project, why not do this from the very beginning?

Android is still very early in his life, and some children who cut their teeth on the App inventor want to dive even deeper into the platform. Anyway, I think Google should consider putting more resources into making the App inventor more intuitive, expanding its functionality and then run additional learning tools to help students make the transition by using the drag-and-drop interface to Java and/or HTML5.  I hope that is exactly what will happen at the Massachusetts Institute of technology. But I wonder why Google does not find it necessary to see it through.

Here's an excerpt from Google's post, which was written by Hal Abelson, Professor of computer science and engineering at the Massachusetts Institute of technology:

App inventor for Android is a programming system that makes it easy for students to create mobile applications for Android smartphones — currently supports a community of about 100 000 teachers, students and hobbyists. Through these new initiatives at the MIT Center for mobile learning inventor App will connect to the Prime research at the Massachusetts Institute of technology in educational technologies and MIT'S long record of creation and support of open source software.

Google first launched the App inventor internally in order to move forward with speed and focus and transformed it to the point where he began to gain critical mass. Now, his influence can be compounded by cooperation with top academic institution. MIT Inventor of the App will adopt enriched studies with greater opportunities to influence the educational community. In a sense, the inventor of the App is now full circle, as I actually initiated the inventor of the App by Google, offering it as a project during my sabbatical with the company in 2008. The main code for the application of inventor Eric Klopfer laboratory and inspiration from Mitch Resnick zero project. The new Center is an excellent example of how industry and academia can effectively work together to create change, thanks to technology, and we look forward to what we can do next, however.
