Tagging students in schools

This week a school district in San Antonio in Texas USA approved a program for tagging students while they are in school. The students will have to wear a small card at all times while in the school so that their positions can be constantly monitored by the authorities.

The RFID tags will be provided free of charge but if they lose or destroy it the student will have to pay $15 for a new one.

The schools that are implementing the project on a trial basis state that they want to “harness the power of the technology to make schools safer, know where our students are all the time in school, and increase revenues,”

‘Increase revenues’ is the part that catches my eye the most here, why might the project increase revenue? The answer is in attendance, the schools receive state funding based upon attendance and how many special needs children take the school buses, in this case based upon the related Medicare payments.

The schools hope to make about $1.7 million a year, and with the cost of setting up the scheme about half a million and about $135 thousand a year to run they are ‘quids in’ as we say in Manchester.

Rather unsurprisingly some of the parents of the children that attend the 2 pilot schools have expressed some reservations. Privacy issues due to the invasive nature of the idea have been raised, and some argue that kidnapping and related horrors could even be made easier if someone managed to gain access to the system and the real time information that it produced.

This news reminds me of an article that I wrote a few years ago on the Bassetti Foundation website regarding spying technology and later its proposed uses in schools in Italy. Here is a mention on a blog related to the matter in question. As this article suggests, the problem of mobile phone use in schools and particularly for cheating in tests and exams is apparently rife, so one school bought a military jammer that blocks the signal making the phone system non operational.

This event also caused a few raised eyebrows (to say the least) with people claiming the right to contact their children in emergency situations. Problems of overspill and local disturbances were also raised but the school argued that the system was necessary in order to uphold the school rules and quality and reliability of its exam process. The law has now changed so the system is no longer in use but the will and means was there.

Coaxing and encouragement while at school and the notion of doing the right thing seem to be out of the door then!

As a note I was a teacher in an Italian secondary school for 11 years myself, and I don’t think this approach will work. Kids are smart.

Asteroid Mining

Last week an American Venture called Planetary Resources, Inc unveiled a plan to send a fleet of spaceship into near space to review the possibility of mining on asteroids.

Apparently there are thousands of asteroids close enough to make them attractive as they hold treasures worth fortunes in the form of platinum and other metals of the same group.

This one is mine!

Precious metals are not the only riches available however, and strangely enough plans are afoot to look for water. Water is an important material in space flight, because it can be used to produce the hydrogen and oxygen needed to power rockets, so an asteroid could represent a kind of modern day re-fueling station. This could make space travel cheaper because once rockets had left the atmosphere they could be refueled in space, eliminating the need to carry the excess weight during lift off.

All of this is in the future of course, but the project has plenty of backing from among others Larry Page of Google and filmmaker James Cameron.

These unfolding events bring some tricky questions however regarding the exploitation rights of near space objects. At the moment there is actually a subsection of international law called Space Law, governed by the Outer Space Treaty that was signed in 1967.

The writers did not envisage such monumental strides in technological advancement however and although the treaty makes clear that States cannot take celestial bodies as their own, they do retain jurisdiction and control over the object if they are the first to land on it.

A precedent has already been set as articles collected in Space have already been sold to private bidders by the Russian government. An article in this week’s wired goes into much greater detail.

It all looks a bit far fetched at times but supporters claim that the idea is no stranger than deep sea drilling for oil. It reminds me somewhat of the great gold rush events in the US of covered wagons and horses, only this time the means of transport differ and the digging is done by machine. Or maybe they will bring back entire asteroids and break them up on Earth, we will just have to wait and see. This article offers a glimpse at some possibilities.

There are obviously plenty of technological improvements required before any of this becomes concrete, but also a lot of legal and ethical issues need to be addressed. As ever one thing is certain, there’s big money in it for someone if it can be done!

What makes the new iPad different?

The launch of Apple’s latest third generation iPad, the interestingly named ‘The new iPad’, sees more revolutionary technological developments, as Apple updates its iconic tablet. In this article I am going to explore some of the exciting and innovative new features, which make the new iPad stand out from the crowd.

Retina Display

One enhancement that is currently getting a lot of attention is the innovation that is the new ‘Retina display’ technology.

The Retina display focuses on the increased clarity of large format display visuals. The new iPad features a sharply improved image capability which now has a 2048×1536 resolution screen and 44% improved colour saturation, with a superior 3.1 million pixels, within in its 9.7 (24.6com) display. Pretty impressive for a tablet PC.

The third generation of the iPadThis technology means that from normal viewing distance, the naked human eye cannot detect any pixelation, as the screen produced images with outstanding sharpness, colour detail and quality.

The improved display really enhances the viewing experience, and I think that it has set Apple ahead of its competitors, in terms of the quality of screen, at least for the time being.

The tablet is designed to show HD media, and with its new awesome screen quality, the viewing of text, photo and video is to the next level!

5MP iSight Camera

Aside from the Retina update, another key improvement is the 5-megapixel iSight camera – Apple are very creative with their names! The new camera features enhanced optics, auto white balance and a face detection features, turning your tablet into an outstanding digital camera. These updates have significantly improved the  picture and video capture performance. Match that with the new Retina display, and it means that you can capture and play media in outstanding quality.

Wi-Fi and 4G

In the latest model of the iPad, Apple have inbuilt Wif-Fi + 4G technology. This technology helps ensure the tablet is able to get a fast network connection, so you can get a seamless uninterrupted stream. Streaming online video is smoother than ever, and VoIP becomes a more viable method of communication.

Battery Life

Despite the outstanding screen display, the high quality camera, and the improved connectivity, something which many critics believe has let the new iPad down is its battery life. Like its predecessors, the new iPad can only handle 10 hours of media before it runs out of juice. The new features have been designed to be more efficient, however the battery life remains pretty much the same as before. Disappointing, or to be expected?

This latest release of the iPad has given techies a lot to be excited about, which is probably why many people queued for hours to get their hands on one, as soon as they were released.
