Basic Computer Skills



Technology plays a major role in School Library Media Centers.  The following list of suggested skills are those most frequently used by media specialists.  This is by no means intended to be inclusive, nor mandatory, however it is a self-evaluative tool that can be used to determine the skills one has, needs, and is willing to learn.  There are many books, free online tutorials, and computer classes offered by various districts, community colleges, etc.  The skills listed were selected based on frequently asked questions and tasks media specialists' perform for faculty, staff and students.
Check  (ΓΌ) the skills you feel you have mastered.

How is radiation effect to eyes between CRT, plasma,& LCD TV?

Electron tube screens found in classic TVs use high voltage in vacuum capsules just as the classic X-ray machine does.
But x-ray emission has several frequencies, the higher being the problematic (energetic) ones.
B&W TV's didn't have emission problems because the high voltaje used was under 10000 volts, and at that voltage no X-ray is produced.
Color TV's, use 21000 and even 22000 volts. More is prohibited, as at that voltages X-rays are produced in huge quantities.
At 21000-22000 volts the X-rays produced are low power and rather scarce, but if next to the screen, where they're concentrated, it's been suggested that they might be harmful to health. Which it is.
Plasmas are made out of low emission cells, and no radiation is generated toward the viewer.
LCD's are almost powerless, except for the fluorescent tubes used as backlight, which make no problem at all.
Mind X-rays don't harm eyes only, but every cell they can reach.
Then, you can watch closer Plasmas and LCD's with no risk, except for visual fatigue.

Snapchat hack affects 4.6 million users


Snapchat logo Gibson Security said it had warned Snapchat about vulnerabilities in its app
The usernames and phone numbers for 4.6 million Snapchat accounts have been downloaded by hackers, who temporarily posted the data online.
A website called SnapchatDB released the data but censored the last two digits of the phone numbers.
It has since been taken offline but a cached version is still available.
The hack comes days after an Australian firm, Gibson Security, warned of vulnerabilities in Snapchat's app which it said could be exploited by hackers.
Gibson Security said it was not involved in the hack: "We know nothing about SnapchatDB, but it was a matter of time till something like that happened," the firm tweeted.
The hackers behind the website that published the data said they had exploited the security flaw highlighted by Gibson Security.
"We used a modified version of gibsonsec's exploit/method," they were quoted as saying by tech blog, Tech Crunch.
Stronger safeguards?
Their latest changes are still not too hard to circumvent”

Snapchat has grown in popularity as an app that allows people to share pictures, safe in the knowledge they delete themselves after being viewed.
It has a feature called Find Friends, which allows users to upload their address book contacts to help find friends who are also using the service.
In its report published on 25 December, Gibson Security warned that a vulnerability on the Snapchat app could be used to reveal the phone numbers of users.
The firm said it had first warned Snapchat about this four months ago, adding that "nothing had been really been improved upon".
Vulnerability Gibson claimed that it had been able to crunch through ten thousand phone numbers of Snapchat users "in approximately 7 minutes on a gigabit line on a virtual server".
In response to the Gibson report, Snapchat acknowledged a potential vulnerability but said it had taken measures to protect user data.
"Theoretically, if someone were able to upload a huge set of phone numbers, like every number in an area code, or every possible number in the US, they could create a database of the results and match usernames to phone numbers that way," it said in a blogpost last week.
"Over the past year we've implemented various safeguards to make it more difficult to do. We recently added additional counter-measures and continue to make improvements to combat spam and abuse."
However, the hackers behind the SnapchatDB, the site that published the phone numbers, said the measures were not strong enough.
"Even now the exploit persists. It is still possible to scrape this data on a large scale," they claimed.
"Their latest changes are still not too hard to circumvent."
