It has already been christened the Display-Cam, one of the future products that the Cupertino home Steve Jobs patented. It is a device that apparently is like a normal monitor but inside, it has sensors that recognition can capture still images and video.

In Apple have given the code name of sensing display (Literally perceptual display) which has characteristics of the output device to display images, but for the first time the input to acquire the surrounding environment. But let’s see the advantages reported: first, we will finally have the opportunity in a video conference to look into his eyes, which is impossible until now because they usually look in the webcam is directed away from the monitor. There will also be the opportunity to save space dedicated to the webcam which can be used for a larger monitor.

The project will then be passed on the iPhone and iPod Touch to arrive on the Notebook. In fact in the patent it comes to PCs but also PDAs and cell phones. It is rumored that the product will already be presented to WWDC 2009But nothing is official yet.

Yet all unofficial, but with a thread of truth more and more evident. We are talking of launching a new platform for notebook at home AMD which will probably be presented to Computex of June 2009. According to the Chinese newspaper, the Commercial Times, the AMD has completed a project code-named Tigris. It would be a 45-nanometer dual-core CPU “Caspian”, equipped on a RS880M chipset and a GPU at 55 nanometers or 40 nanometers will have a label that stands M9X.

The giant AMD has always competitor of Intel, which continues to churn out news of late, could reveal, always at Computex, the development platform designed for 2010 based on a quad-core 45-nanometer “Champlain” and a chipset with SB8xxM serious. This new platform for the coming year, should support DDR3 memory, a USB 3.0 and a completely new GPU which should be called Manhattan.

The platform Tigris, according to Commercial Times, is aimed at laptops with 14-inch monitor or more, of platforms is expected to be submitted Yokun and Congo covering the range of 13-inch netbook down.

The HD is not enough anymore? No problem. Hypothetically you could soon find full listings to view in 3D. The U.S. market has already been activated in this respect, it is news these days that Direct TV as Sky, will launch in 2010 a channel in high definition and in 3D. The same type that is already occasionally used in some types of film at the cinema.

It was the very success of some films to shift attention among producers and networks to this new technology, which thankfully has nothing to do with the first and clumsy attempts to three-dimensional movies of the 90s. An innovation that threatens to seriously change the conception that we have entertainment and television. A change facilitated by the electronics industry that sees itself first of all, the LG and Sony to focus on 3D as a new target market on which to build new LCD TVs.

The news for both stations, was announced through press releases and some excellent results and enthusiastic persuasive presentations at past CES 2010 in Las Vegas, Nevada. Although the transition to HD seems easier than expected, it should be noted that using this type of transmission will be necessary to have compatible equipment and television special glasses suitable for three-dimensional vision. At the technological level, for the end user, the transition to a 3D entertainment might be rather expensive. One problem that industry experts are already working to solve through the creation of better and less invasive technologies to be used.

The first programs to ferry the three-dimensional technology will be in homes, sports programs, the easiest at the time, to make it suitable for the transmission in 3D. The first to opt for this type of technology will be ESPN. Different matter when it comes to Italy. While in Europe the first experiment in this direction will be conducted this year in Britain, the slow diffusion of HD in our country does not bode well for landing in a rapid three-dimensional television.

Apple, A1080, battery, portable, right for, you,2GB, RAM, LCD,computer

There is a brief guide to buying a laptop. We can divide the notebook into two major categories. Notebooks and Laptops to work for the home. Today the so-called Laptops for the business are sold at affordable prices, which until qulche years ago did not happen. The prices have had a significant decrease, so now you can buy a good notebook to work spending around € 900.

Business Laptops . The needs of those who buy a laptop for work are usually higher than those who use the notebook for the home or perhaps just to study. In general, the performance should be superior, with better screen, because the amount of hours spent at the computer is high, with a good video card, hard drive more ‘roomy, most processors’ performance and, especially with the new operating system Windows Vista, we recommend at least 2GB of RAM, Wi-Fi connectivity. All factors affecting the price. However, before buying a notebook and evaluate the good that we will make specific use, to avoid unnecessary waste of money.

Laptops for home . Who buys a laptop for home needs a PC with a good multimedia: a chance to see the film, perhaps by connecting the notebook to a LCD TV, listening to music, play. Here too we need to evaluate thoroughly before buying a notebook, the specific use in when we’re going to make such a good graphics card for games of last generation has a significant impact on the price or the most ‘demanding want to choose a laptop equipped Blu-Ray technology.

Some questions to the best of the Handset. If we buy a notebook, to avoid unnecessary waste of money, we estimate that we will use it and we always ask:

When you weigh?

Battery Life?

What wireless links?

Processor that has (not recommend-performing processors, specic with the new Windows Vista operating systems)?

How much RAM memory your laptop (with Windows Vista we recommend at least 2GB)?

How many have your notebook’s USB port (we recommend at least 3 USB 2.0)?

What operating system uses the laptop (Vista with the Aero interface suggest)?

The handset has other software (better a PC that already has a good supply of programs)?

How much has the notebook warranty (two years of the European Union is borne by the producer)?

If purchasing online is who will bear the withdrawal and return in the event of warranty service?

It can buy an extended warranty, at what price?

The hard drive is a device still in action. You will hear its noise every time you call a program, start Windows, deleted files and so on. However, it should not “boo” all the time.

If you feel that your hard drive makes too much noise, it might be too close to the exhaustion of the free space that is fragmented or disproportionately.

Excessive hard disk activity is the main cause of failure. If you have a small amount of RAM (remember, stands for Random Access Memory), say 64 MB or less, consider upgrading the system as soon as possible. You should also frequently start Disk Defragmenter at least once a week. Why? Very easy to maintain and / or make your hard drive healthy, faster and more efficient.

Just go to Start menu – Programs – Accessories – System Tools, select “Disk Defragmenter”. It may take some time to defragment your hard (sometimes even several hours) but you’ll be rewarded with faster performance and longer life of your hard disk.

Not negligible for decent performance in a low-end notebook is the type of software installed. First, the operating system, if we can choose what kind of OS include, certainly opt for Windows XP than the heaviest view.

Vista was created with the prerogatives of hardware high-profile, if we look at the amount of resources it uses, we understand that a laptop will find it hard economic hell.

So XP will be the choice where to direct us, be sure to do so prior to purchase for the hardware in your notebook is not missing the driver release for Windows XP.

It is important, because some homes accertatevene release drivers for the operating system only when purchasing, and right now it is almost always the view.

An evaluation of a personal nature, dictated by work, that I just want to share is as follows: my notebook is updated to Service Pack 2 and later updates I chose not to run the Windows XP service pack 3 to my mind slows down not just processes. Block updates to SP2 will certainly have an effect on small leaks in security, but they are a trifle compared with the lightness maintained by the operating system. At this point you are free to decide for yourself.

A note, remember those who did not know that Windows XP (32-bit version) has the limit to “see” and then you can use up to 3 GB of RAM, this should be borne in mind in which case you want to expand this capacity over the ram . To work around this limitation you can install Windows XP 64-bit (normally referred to but are not drivers for the hardware), or alternatively view, although in view of a low-end notebook 3GB RAM really many.

An important hint on other software installed on your laptop, if you opt for older versions. And ‘demonstrated that the same windows media player 10 and 11, has a downloadable web resource consumption much higher than that reported after the default installation of Windows XP.

Same for the office suite of software, older versions (Office XP or Office 2003) are much lighter (just consider the consumption of resources to realize) the latest release. Always performing as openoffice opensource versions instead (which I highly recommend to try sooner or later).

This section ends with the latter that he wanted to be a small guide to the acquisition, evaluation and use of a cheap notebook. All those written not want to be absolute rules on the choice of laptop to buy, but a way to reflect on the fact that you do not need a laptop for over a thousand euro to get a satisfactory product, as this depends entirely on what kind of use we are going to it.

A little as someone who buys a guitar from thousands of euro, and brings together two agreements, who can (economically) and do not want to hear it has all the right reasons, but certainly did not do a deal.

First, we start by saying that the term Virus is an often abused. Unfortunately the same thing that happened with the term “hacker” now in common usage in the sense of crackers.

In common parlance, in fact, many use the term virus to indicate, in fact, an abundance of harmful elements that, instead, should be identified by the term malware (malicious software or Malicios Software) or badware…

This “malware” is nothing but a program (or part thereof) that “does something that if we knew not let them do” as I usually call me.

This “something” can range from simple information gathering to the redirection of web pages visited, the exploitation of our connection to the exploitation of our processor, automatic sending of spam from your computer to download other malicious software in short, nothing pleasant .

Is classified as Malware?

Depending on the function of the modus operandi, the structure of the code used in the Malware can be classified into several categories:

* Virus

* Worm

* Trojan Horse

* Rootkit

* Backdoor

* Keyogger

* Botnet

* Dialer

* AdWare

* Spyware

* Downloader

* Exploit

* Spam

* Hoax

There are other minor categories such as Rogue Software (never heard of the infamous Antivirus 2009?).

Therefore, let’s define what these are and what they do “nice” guests once they have settled into our system.

Definitions.

• VIRUS

A virus itself has the ability to copy itself on a computer without the user’s awareness.

A virus itself has the sole ability to copy itself from one computer to another in the form of executable code (for example through the use of USB drives, CD / DVD or other media over the Internet or a LAN) and attacks another program by copying it in its own malicious code.

• WORM

The Worm (worm) is similar to the virus and also has the ability to spread in a network without user intervention or knowledge, but is not included in the code of other programs being himself an executable program.

Tended harm to a network (bandwidth consumption, packet collision, etc.) and not to computer files as it does a Virus.

• TROJAN HORSE (or Trojan)

The word itself (Trojan Horse) gives some idea of what a Trojan: A program that promises one thing (pleasant, desirable) and does another (unpleasant, undesirable).

Usually they are voluntarily downloaded from the Internet consciously by someone ignorant of the ultimate goal of the application that can range from destruction of data to an attack DoS (Denial of Service).

Typically has a catchy name and / or harmless:

screensaver.exe – sex.exe – telefonogratis.exe – downloadWindowsMediaPlayer.exe

• ROOTKIT

I will not elaborate on the explanation of the origin of the name for which refer to reading this article.

A rootkit is a malware (the above categories are not exclusive) with the ability to completely hide the system (can not find the files that make up the processes, registry keys etc. ..).

• BACKDOOR

A Backdoor (back door) denotes a secure access to those who have already made a connection to a goal (our computer, unfortunately).

Once you open this door (it may be a program as an inherent vulnerability of a system or software) the attacker is always the door open to come back and do more “damage.”

• BOTNET

A botnet is a network of computers (called zombie) compentence controlled by a remote user.

It is used to attack other systems through a node system on the botnet so attacked the attack is detected as having been made by one of these (ignorant) nodes.

• KEYLOGGER

A keylogger is a program that can intercept keystrokes pressed to rebuild the user’s typing and send it to a remote user or save it locally for future reference.

There are also hardware keyloggers.

• DIALER

A dialer creates, without your knowledge, a new telephone line connection or ISDN and consists, in general, premium rate number that drives the phone bill.

With the spread of DSL connections are gradually disappearing.

• ADWARE

Adware will go with the term to refer to all those who view software, download it or play advertisements.

They are considered dangerous because many of them are also Spyware.

The advertisements, however, are used by developers to keep the costs of software production. The most popular programs are Adware: eMule_Adunanza, Eudora, Daemon Tools, RealPlayer and Messenger Plus! Live.

• SPYWARE

We identify with this term all the programs that gather information on uses, customs and user data without his consent and transmitted through the Internet.

The most popular spyware consist Zango Search Assistant and SonicMail

• DOWNLOADER

As mentioned in the category of programs that perform all the Downloader to download other malware on the target computer.

• EXPLOIT

Exploit The term refers to a program (or part thereof), a set of data, especially sending packets over the Internet or a sequence of commands that could exploit a vulnerability in a target system or software installed on it.

In December 2005 it was discovered a vulnerability in Windows Metafile that allowed the attack with the simple insertion of a clip in this format in an email, it was not necessary that the user opened or i ran no content: the simple view of ‘preview of the email in question caused the exploit in the target system by installing a Trojan.

• SPAM

The Spam is the so-called “junk mail”. It may contain other types of Malware.

• HOAX

This is called “Buffalo” or false information in attempting to mislead with aspects of verosomiglianza facts or actual things and tends to throw into confusion the recipient of the information.

I have received email according to which the famous MSN Messenger would become “paid” by one of my contacts (which I promptly rebuked and informed)!

Conclusions

I tried to make this series definition as accessible as possible to those of computer security and knows very little, hoping to shed light on some little known aspects.

A quick debunk some myths about Virus, Antivirus, and Security.

Working with half as multifunctional and chameleonic as the computer can lead to a duty not to focus on the tasks to be performed, to lose too much time with applications that you should not even open every day and find themselves overworked because of too many delays.

The remedy to this situation is constantly monitoring the time spent in carrying out various activities to the computer and one of the best ways to do this is Grindstone, a free program that allows you to set up a comprehensive list of things to do full time, date and time within which to complete the work.

The software comes with a user interface easy and quick to use (if you know a little ‘in English), which set up through their activities, set a deadline and start the timer that will reveal how and how much we spent our time.

Among the main advantages of this program a bar across the top of the desktop with which to monitor the status of various activities, move from one engagement to another, and pause the timing used to do the job, and recognition Automatic time spent away from the computer which makes it ideal for the Grindstone “measure” the commitments undertaken with the PC.

The program includes a comprehensive system of reminders, supports the management of multiple users and includes a timer for general use in the conduct of business “mixed” (eg, reading e-mail, access to certain Internet sites, etc.)..

In short, if you were looking for a companion work that would allow you to organize and monitor the time it takes to do your job to the PC, look no further.

Grindstone is free to download from the Download section of all notebooks by clicking here.
