How to get the most enjoyment from your
color TV set


Your new color TV incorporates a host of features designed to give you excellent performance. Besides, this model utilizes a highly sophisticated control microprocessor that can give you unprecedented convenience and control in the areas of picture adjustment, channel tuning, monitor operation, on-screen information, and remote control.

We therefore strongly urge that you read all of these instructions before using yourTV for the first time.

Installation

Antenna

Unless your TV is connected to a cable TV system, or to a centralized antenna system, a good outdoor color TV antenna is recommended for the best performance. However, if you are located in a strong signal area that is free from interference and ghost conditions (multipath), an indoor antenna may be sufficient. The two pole antenna packedwith this set is for your convenience only. It is not capable of providing you with the sharp detail and rich color that this televisionwas designed to display.

Location

Select an area where sunlight or bright indoor illumination will not fall directly on the picture screen. Also, be sure that the location selected allows a free flow of air to and fromthe perforated back cover of the set.

Note

Never remove the back cover of the set. This can expose you to very high voltage and other hazards.

If the set does not operate properly, unplug it and call your dealer or service shop.

Informatics education:
Europe cannot afford to miss the boat

Principies for an effective informatics curriculum

        The committee performed a comprehensive review of the considerabie existing material on building informatics curricula, including among many others the (UK) Royal Society report, the CSPrinciples site, the Computing at Schools Initiative, and the work of the CSTA. Two major conclusions follow from that review.

        The first is the sheer number of existing experiences demonstrating that it is indeed possible to teach informatics successfully in primary and secondary education. The second conclusion is in the form of two core principies for such curricula. Existing experiences use a wide variety of approaches; there is no standard curriculum yet, and it was not part of the Committee's mission to define such a standard informatics curriculum for the whole of Europe. The committee has found, however, that while views diverge on the details, a remarkable consensus exists among experts on the basics of what a school informatics curriculum should (and should not) include. On the basis of that existing work, the Committee has identified two principies: leverage students' creativity, emphasize quality.

Leverage student creativity

        A powerful aid for informatics teaching is the topic's potential for stimulating students; creativity. The barriers to innovation are often lower than in other disciplines; the technical equipment (computers) is ubiquitous and considerably less expensive. Opportunities exist even for a beginner: with proper guidance, a Creative student can quickly start writing a program or a Web Service, see the results right away, and make them available to numerous other people. Informatics education should draw on this phenomenon and channel the creativity into useful directions, while warning students away from nefarious directions such as destructive "hacking". The example of HFOSS (Humanitarian Free and Open Software Systems)
shows the way towards constructive societal contributions based on informatics.

        Informatics education must not just dwell on imparting information to students. It must draw attention to aspects of informatics that immediately appeal to young students, to encourage interaction, to bring abstract concepts to life through visualization and animation; a typical application of this idea is the careful use of (non- violent) games.

Foster quality

        Curious students are always going to learn some IT and in particular some programming outside of informatics education through games scripting, Web site development, or adding software components to social networks. Informatics education must emphasize quality, in particular software quality, including the need for correctness (proper functioning of software), for good user interfaces, for taking the needs of users into consideration including psychological and social concerns. The role of informatics education here is:

• To convey the distinction between mere "coding" and software development as a constructive activity based on scientific and engineering principies.
• To dispel the wrong image of programming as an activity for "nerds" and emphasize its human, user-centered aspects, a focus that helps attract students of both genders.

Breaking the teacher availability deadlock

        An obstacle to generalizing informatics education is the lack of teachers. It follows from a chicken-and-egg problem: as long as informatics is not in the curriculum, there is Iittle incentive to educate teachers in the subject; as long as there are no teachers, there is Iittle incentive to introduce the subject.

        To bring informatics education to the levei that their schools deserve, European countries will have to take both long-term and short-term initiatives:

• Universities, in particular through their informatics departments, must put in place comprehensive programs to train informatics teachers, able to teach digital literacy and informatics under the same intellectual standards as in mathematics, physics and other Sciences.

• The current chicken-and-egg situation is not an excuse for deferring the start of urgently needed efforts. Existing experiences conclusively show that it is possible to break the deadlock. For example, a recent New York Times article explains how IT companies such as Microsoft and Google, conscious of the need to improve the state of education, allow some of their most committed engineers and researchers in the US to pair up with high school teachers to teach computational thinking. In Russia, it is common for academics who graduated from the best high schools to go back to these schools, also on a volunteer basis, and help teachers introduce the concepts of modern informatics. Ali these efforts respect the principie that outsiders must always be paired with current high-school teachers.

Eric Schmidt says encryption will help Google crack Chinese censorship and stop the NSA

By Rich McCormick on January 24, 2014 02:08 am Email

Eric Schmidt thinks encryption is the answer to many of the internefs problems. Google's executive chairman said last November that "encrypting everything" could "end government censorship in a decade." Now Schmidt says that in that same decade, encryption could "open up countries with strict censorship laws," giving their people "a voice."

Speaking at the World Economic Forum in Davos, Schmidt said that Google was attempting to strengthen its encryption so the world's governments "won't be able to penetrate it" and obtain private data. Those efforts, Schmidt said, would create particular problems for "governments like China's," which he thought responsible for "80 to 85 percent of the world's industrial espionage." The Google chairman also said he saw the eventual relaxation of Chinese censorship over time as the number of people using social media in the country continued to grow.

Schmidt suggested the debate over the NSA surveillance scandal was good for the world, but also chastised the US government, saying "because you can do this monitoring does not mean you should do this monitoring." He was also asked his reaction to comments made by Microsoft that suggested non-US customers would be able to store their data outside of the US. "I don't understand it," was his reply.
