What is HPET and how to make it speed up your computer

The HPET an acronym for the phrase High Precision Event Timer is a piece Hardware has been developed by Intel Corporation is working on a "clock" Clock (an hour Hardware and not Software) and the role it imposes on operating systems and programs in support of technology High Precision Event Timer use hour instead of using the HPET cpu TSC in Albrosisr or Mistalh it b time stamp counter, so what is available upon the accuracy of HPET more. And make sync work to be successful

Of course here I must point out that Mannih hourly Clock rate is the frequency in which they operate, whether it cut hardware processor or any other piece, and whenever high-frequency hertz, this reflected positively on the speed.
Thus When enabled HPET in the BIOS as well as Windows, we impose on the system and the programs that use the HPET instead use the cpu TSC located in Albrosisr.

How to activate the HPET in the BIOS.


First, it is very difficult to answer this question, because the settings BIOS vary from one computer to another, but on the whole method of access to the BIOS may be after you restart the computer and the emergence of Oڭo device Zguet button F2 or F10 or DEL or thinkvantage If your computer from one type to Inoڤo Lenovo and track Altalmyat , now permeated the emergence of some BIOS Commence in Browse all the settings until you find HPET then activate it and save these settings by pressing the button F10.

Now after restarting the computer and the appearance of Windows, run the command prompt, the command line, type the powers Director was the following line in order to activate the HPET in Windows

bcdedit /set useplatformclock true

In case you wish to stop can write the following line:

bcdedit /deletevalue useplatformclock

Now in order to be sure that he was activating the HPET in Windows, download the program follows the bottom of the entry WinTimerTester, where it should find a frequency of at least 14.3, if it was 3.4 or less is less than this, it means that your computer is either not supporting technology HPET or that the property is disabled properly.


To indicate that the technique HPET is not found in all computers for this you must be sure of their presence in your computer by checking the BIOS, either if you activate it and found that Windows or some of the programs have become unstable, it is very likely just disable this feature through the command line referred him in the top post.

Discover the most powerful Camera in the world

With the tremendous development that we are witnessing today in the industry of high-precision cameras and speed, has been developing very fast cameras can capture millions of images per second, which is used especially in the field of research and Kvezia quantum science for the study of movement and so on.
In this context, we find various students and scholars of major universities in the world are competing to develop and manufacture faster and better camera adoption of techniques and studies very precise, it is imperative and you saw a documentary describes and explains how the explosion occurred given or how "jumped Bergute quickly fictional does not see with the naked eye," and the adoption of imaging techniques is very slow, based on the thousands of pictures taken it in a second, but when I hear about 4.4 trillion frames per second is something chilling.

In this post we'll look at the fastest camera in the world, and would leave the planet Japan, where it was the launch of a huge project by scientists at the University of Tokyo University of Tokyo and Keio University Keio University to create a camera "miraculous" can capture 4.4 trillion (4.4 trillion) images per second! The thing that will make it possible to see what was not seen by humans before, such as a video camera describes the millions of parts from the second occurrence of the phenomenon of lightning, or capture the movement of the fastest bird in the world, where the movement will become very, very slow to make it easier for scientists and researchers to study this type of movement.

 

He has developed these scientists private room camera (large size up to 1 meter), where they can study received act of samples of chemical or biological weapons are very accurate, has been named this technique b STAMP short for (Sequentially Timed All-optical Mapping Photography) where up accuracy current 450 * 450 pixels, this camera is a thousand times faster than high-speed cameras that are currently available.

 

He says Keisuke Goda professor of chemistry at the University of the University of Tokyo and one of the participants in the project, that in the year 2007 they talked about 95 thousand frames per second, and in 2009 the number jumped to reach six million frames per second, up to what it is now something that took three years of development, and Sertqub that there are practical applications in various fields within the next two years Kamiadin Health and laser therapy and ultrasound, will also be a powerful tool for scientists, working on the photochemistry (photochemistry) and quantum physics and plasma (plasma physics) and electrons axial (spintronics), waiting for the development of equipment and techniques currently used by the camera to become smaller and lighter, and when he does not like the cameras manual currently available.

Find out the first person invented of computer and his technical specifications

The computer has become one of the most commonly used devices in the modern era, no longer limited to the military sphere, but only became used in many personal civic activities.


There is no doubt that any researcher on the subject of the invention of the first computer will find a conflict between those who say that Howard Aiken is the inventor of the first computer and says that Conrad Suzh Konrad Zuse is invented the first computers but on the whole the German Konrad Suzh is the first to ask a computer programmable in 1941 invented for z3.

Which is the first device Negotiable Qaam calculations Atutumetekih and correct and has been working processor frequency between 5 Hz to 10 Hz from a class where I use 22-bit in the Research Institute of the German Air Force to conduct analyzes and statistical disorder aircraft wings. And are programmed by 3 perforated cards (the process of entering information into a computer).


  But in 1944 put Howard Howard Hathaway Aiken Aiken which is an American mathematician invented the Harvard Mark 1, which weighed 35 tons and 800 thread wired and can accurately account until the twenty-third position after the decimal point.

It was used as machine read punched cards to Hulrit and can be controlled through a series of instructions on the perforated paper tape, and that the process of introduction of operations for the device was done by Use perforated cards where the device outputs the results in other papers.

Of course Harvard Mark 1 was not only a series of successes since then has Howard Ekin subtracting the Harvard Mark 2 and Mark 3, which was Bstkhaddm some electronic components with mechanics either Marc 4, all electronic Mkontadth where it will be used for the first time on CD-ROM.

Why we write @ in email and what story about this coding ?

Perhaps you use this code on a daily basis but do you ever wondered why we left no coding @ in email or by logging on when you send e-mail ?

Well in this post'll give about the story and why this coding is used to this day! . The whole story began when he succeeded all of Ray Tomlinson and Beranek and Newman in sending the first email in 1971. But the problem is that Sadfthma is that e-mail was who did not get but one user on one computer so if he wanted Ray Tomlinson sent several e-mails to multiple users at the computer one so that each user reach its mission solo for the rest of his colleagues, and that was not possible, but it requires it to be available each user on the computer of his own, which he can not be available at that time, but after that felt by the inventor of the idea of ​​coded e-mail from which differentiates between the sender's address in the name of the user who wants to convey to him the message that there is a computer and the e-mail program. As the inventors Think he must have this codec is not used in the name.

Thus found Aenahm to encode @ in the keyboard and came to be are used, in order to differentiate between the user name as well as the computer, which resides upon the program of e-mail, and has already managed to send email and one to several users on the same computer so that each name is received Emile solo for the rest of his colleagues even though they are on the same computer .

  And to the limits of time left this codec is that distinguishes between user name and address as well as the Computer [nickname @ host] which it resides e-mail program.

Find out the Lifetime of your computer .

Computer counting device that it indispensable in the home, there are those used for entertainment, and there are those who used to work, and there are those who combine the two. If the computer is a blending between the hardware and the software for the latter period of life, duration of life has meant not only the computer crashes cut hardware, but also when the computer is not able to run the new operating systems and software / games.

For example, companies programmed for programs in each version may add new features and other functions of the program calls with technical specifications especially to run, as is the case as well as for electronic games in each new version requires settings and specifications of a new computer this specification if were not present, computer becomes unable to keep up with this development Kmthela when we say that the Pentium 4 computers is now able to run Windows 7 or Windows 8, these computers have expired old must change.

Microsoft company says in a publication about the life cycle of a computer. The life cycle of a computer is defined in 4 years and this means that when you buy a new computer for the virtual life be 4 years then you will find problems running some programs / games ...


As the duration of the life of a computer is not a hostage only Balsovrudolf but also hardware, for example, the battery in the laptop computers they also have a life span has lengthened or shortened depending on how you use him, but on the whole, the battery life expires completely after two years or four years at the latest estimate by using computer, Mac and reverse battery, which can last 5 years.


The hard disk has up his tenure to more than 4 years if the work 24/24 7/7 Aimam given an overall duration of life for a disk drive. The long-term or shorten depending on how the user to deal with the computer and how it is managed. As for RAM, it remains hostage to the extent of the evolution of software and operating systems where you might end up when she becomes a chore and you change one larger capacity and greater frequency speed when they become operating systems, programs and games require you to do so.

Find out 7 other operating systems, that you can try Except (Windows, Linux and Mac)

You can not talk about alternative systems without mention of Linux and of course Linux distributions, such as the most famous (ubuntu or mint), and everyone knows it has many users of open-source enthusiasts, but on the whole we will look for other alternative systems may not have heard of before.
You can try it and taken it through the idea of ​​them installed on your imaginary depending on programs such as VirtualBox or VMware.



SteamOS

 

SteamOS is currently in the pilot phase. It is just a distribution of Linux and includes a lot of Linux software routine but began to deviate from this framework to be a stand-alone operating system.
SteamOS is being developed in order to be a new operating system dedicated to computer games comes with a graphical interface is very powerful.
In 2015, will be the launch of the computers that come with SteamOS preinstalled, known as hardware Steam had been read before the establishment of the Alienware plans to release console her new this system, in addition to many of the leading companies in the field of manufacturing of gaming devices as iBuyPower, Falcon Northwest, Gigabyte and will look to cut off these devices Kconsol hardware too strong to be more of a personal computer.
You can download a trial version from here.

 FreeBSD

System open source and free derivative of Unix system just like Linux system, but more closely related to Unix, Linux, compared with that look completely different from Unix, but both used the graphical interface X-Windows.
System occupies most of the programs Linux, where you will not find a big difference between him and the Linux From this perspective has become his users much lately as unique with some features that are not available in Linux and is considered one of the most powerful systems ever to run servers (servers) It is also very good for computers office.

Chrome OS

Google project that I consider unhelpful is a Chrome OS based on the Linux kernel, comes with a desktop or a custom interface software to run Google Chrome Kmtcefh and applications through a Chromebook.
However, there are ways to install Chrome OS on the computer before embarking on buying a Chromebook by downloading this version that allows you the possibility of experimenting with the system and taken it a preconceived idea about it.

Haiku

Was the brainchild of "John Lowe, Casey" in 1990, which created the first nucleus of the system from scratch, has been head of Apple France wearer where he faced many of the problems of corporate competition Kmaikarosowic that were pressuring manufacturers not to the support system BeOS has mandated that 23.5 million dollars due to the call for judicial filed by Be. Has been a recent revival of this system under the name Haiku is a system open source has been developed depending on the system BeOS you can download it and try it because it contains a set of features and is advised by a lot of old equipment.

ReactOS

ReactOS is an open source system, based primarily on Windows NT (built modern versions of the Windows operating system on Windows NT operating system since Windows XP.). In other words, it's an attempt to re-engineer Windows as the operating system is open source and the system can run software applications and the Windows operating system also supports drivers produced for the Windows operating system.
ReactOS plan stipulates that the future is to strengthen networks TCP / IP as well as full support for the USB, and the development of the current user interface (GUI) as well as add support for multimedia and programming language Java and languages​​. NET.

SkyOS

The back of this system in 1996 by Robert Szeleney where open source was then that he turned into a closed source system. Development on SkyOS ended in 2009, but was released the last beta version available as a free download in 2013.
The SkyOS future good option for those who do not wish to use proprietary operating systems or other open source.
This system supports many features such as multiple processors, virtual memory, memory protection, multiple operations. SkyOS system is based on a graphical interface (GUI) called SkyGI.


Syllable

Is an open source operating system forked from AtheOS, which was supposed to be based on a system of AmigaOS.
It is a lightweight operating system such as the Amiga and me, but it was created with many parts of the GNU Linux project.
But the system has a small number of developers and unfortunately recommended for antique devices

Evolution Of Computers

A computer is an electronic machine that accepts data stored, processed according to the instructions provided by a user evolution of computers, and returns the result. Today we take for granted computers, and became part of our daily activities. While computers as we know them today are relatively new, the concepts and evolution of computers ideas behind computers have a bit of history - time for a whirlwind tour of how we arrived at the age of email,evolution of computers YouTube and Facebook.

Human attempts to develop a tool to manipulate the data back to 2600 BC when the Chinese came with the abacus. The slide rule was evolution of computers invented in 1621 and has remained largely unused until the advent of electronic calculators in the 1970s These two examples of the first devices were mechanical and human scale.

In 1830, the English mathematician Charles Babbage designed an Analytical Engine could be programmed using punched cards to perform evolution of computers the calculations. He was different from his predecessors, and has been able to make decisions based on their own calculations, such as sequential, Branching and Looping. Almost all computers used today follow this basic idea under Babbage, so it is evolution of computers often referred to as "the father of computers." The scanner is so complex that Babbage was never able to build a working model of their design. Finally was built over 100 years later by the London Science Museum.
The first electronic computers

Many different types of mechanical devices evolution of computers that followed is based on the idea that the scan engine. The first electronic computers were developed by Konrad Zuse in Germany in the period 1935-1941 Z3 was the first programmable digital computer work fully automatic. The original was destroyed during World War II, but a replica was built by the Deutsches Museum in Munich. Because their systems evolution of computers implemented many concepts we still use in our modern computers, Zuse is often considered the "inventor of the computer."

Around the same time, the British built the evolution of computers Colossus computer to break the encrypted codes for the German war effort, and the Americans built the Electronic Numerical Integrator Analyzer and Computer, or ENIAC. Built between 1943 and 1945, ENIAC weighed 30 tons and was 100 feet long and eight feet high. Both Colossus and ENIAC were based largely on vacuum tubes, which can act as an electronic switch that can turn on and off a lot faster than mechanical switches, which have been used so far evolution of computers . Computer systems that use vacuum tubes are considered the first generation of computers.

The vacuum tubes, however, consumes large amounts of energy, transforming a computer in an oven. The first semiconductor transistor was invented in 1926, but was only in 1947 that became a solid and reliable transistor for use in evolution of computers . In a similar manner a vacuum tube, a transistor controlling the flow of electricity, but was only a few millimeters in size and generates little heat. Computer systems that use transistors are considered the second generation of computers.

It took a few years for the transistor technology evolution of computers to mature, but in 1954 the company introduced the IBM 650, the first computer produced. Today, computers are still using transistors, but are much smaller. Was made in 1958, can combine several components including transistors, circuits and connect them in a single piece of silicon. This was the first integrated circuit. Computer systems that use integrated evolution of computers circuits are considered as the third generation of computers. Integrated circuits have been computer processors we use today.
PCs

Computers are fast becoming more powerful evolution of computers . Became possible to squeeze all the integrated circuits that are part of a single unit in a single chip called a microprocessor in 1970. Computer systems using microprocessors are considered the evolution of computers fourth generation of computers.

In the early 1970s, computers were being used mainly by large corporations, government agencies and universities. The first device to be called a personal computer was introduced in 1975 Altair 8800 was made by systems Micro Instrumentation evolution of computers and Telemetry. It included an Intel 8080 processor and 256 bytes of memory. There were no keyboard, and instead of the programs and the data was captured using switches. There was no monitor, and instead the results were read by interpreting a pattern of evolution of computers small red lights.

This equipment is mainly used by hobbyists and hackers who evolution of computers take them apart and build their own devices. Two of the pirates, Stephen Wozniak and Steve Jobs created a personal computer in 1976 which had a storage keyboard, screen and disc. They called Apple I. Around the same time, two other hackers, Bill Gates and Paul evolution of computers Allen started developing software for the Altair 8800 and founded Microsoft.

DNS Propagation

To resolve a domain name should be registered and made at least two name servers that host the DNS zone file for the specific area dns propagation . These servers are authoritative so when someone in the "application" of the Internet to the IP address of the specific area, the application will be first to the root name servers for the requested domain TLD (top level, for example, com, net, org, etc) dns propagation . They respond with authority name servers for the requested domain and the request goes to the server hosting the file with the DNS records that resolve IP.

Each ISP manages its own DNS server storage cache /  dns propagation . These DNS servers records stored in its local cache to store the voting servers network traffic authoritative name every time they receive a request for a given domain dns propagation . So when you ask your domain name in their browser, the request is sent to the server name of your ISP. The IP address of your domain's authoritative name servers is resolved and the file is stored in the local memory of the ISP name server.

The record remains stored in memory local name server with the settings applied to the DNS zone file, and in particular dns propagation , the TTL parameter in the SOA (Start of Authority) record. This value is set by default to 14,400 seconds (4 hours) in the BIND nameserver. Often, this value increases to a day or two, again due to the economy for  dns propagation traffic.

So when your local name server caches a record of your DNS zone file, holds the record in your memory as long as specified in the TTL parameter its zone file dns propagation . When you make a new application for the same record before the TTL time passes, your ISP name server will respond with the appropriate register, instead of re-interview an authoritative name server and will do so far reaches a lifetime. After reaching life will return dns propagation to your DNS zone from the authoritative name server for the domain and begin using the updated records.

That's why you have to wait until one day dns propagation , when you make changes in the DNS zone.

While waiting for an updated record of spreading dns propagation , it's a good idea to remove the system of local DNS resolution on the PC, because the DNS records can be cached there too. Check out the following links for more information about how to delete DNS cache instructions

What is Samba ?

Samba-server provides a SMB server that can be used to provide network services to what is samba. Samba uses NetBIOS over TCP / IP protocols and does not need NetBEUI what is samba protocol. Samba-2.2 features working SWAT capacity control andincludes NT domain allowing samba smb.conf to be managed remotely through your favorite web browser. For now, it is enabled on the TCP port 901 via xinetd what is samba . SWAT now includes own initialization packet. We encourage users to use what is samba as a Windows domain controller as the networks that do not have a domain controller in Windows NT what is samba . This press release does not yet have the backup control capability field. Please refer to the information what is samba whatsnew.txt fix. This release adds support binary encrypted password. Please read  what is samba the smb.conf file and what is samba  in the docs directory for implementation details.

Samba is a suite of free programs that work together to allow customers to access filespace and printers from a server via SMB what is samba . Originally written for Unix, Samba now works on NetWare, OS / 2, OpenVMS, and a variety of other operating systems. It is especially popular as a set of Linux servers.

Programs in the Samba suite are used to integrate Unix servers with client computers running Windows 95, 98, Me, NT, 2000 or XP or integrate Unix client computers with a Windows server. They are also used to replace protocols such as NFS or Novell NCP, especially where computers are used. In many cases, Samba can completely replace Windows NT, Warp, NFS or NetWare servers.

Samba came from a what is samba mix of musical styles from Africa and Brazil. Samba is played with percussion instruments what is samba and accompanied by guitar and cavaquinho. Generally, the words of what is samba are about romance or what is samba daily life of those living in cities, especially the poor. The word samba is of African origin and its meaning is attached to the typical dances of the continent.

The roots of samba were conducted in Brazil during what is samba the colonial period in Brazil, with the arrival of slave labor in the country.
The first recorded samba in Brazil was "Pelo Telephone" (by telephone), in 1917, and sung by Bahian samba words that were written by Donga and Mauro de Almeida. Samba to the streets and later spread to the carnivals of Brazil what is samba . In this period, the main samba composers were Ismael Silva and Heitor dos Prazeres.

In the 1930s, radio stations began broadcasting Brazilian what is samba to their audiences. The most important composers of this period were samba Christmas Rose, "Bar Talk" Cartola, "As Rosas Não Falam" Dorival Caymmi, "O Que É a Quebec Bahia Tem?" Ary Barroso, "Aquarela do Brasil" and Adoniran Barbosa, composer of what is samba.

In the 1970s and 1980s, a new generation of composers emerged. Paulinho da Viola as Jorge Aragão, João Nogueira, Beth Carvalho, Elza Soares, Dona Ivone Lara, Clementina de Jesus, Chico Buarque, João Bosco and what is samba.

Historically, other important samba composers of all time:what is samba, Ataulfo ​​Alves, Carmen Miranda, Elton Medeiros, Nelson cavaquinho, Lupicinio Rodrigues de Almeida da Demons Aracy Garoa, Isaura Garcia, Candeia, Elis Regina, Nelson Sargento Clara Nunes Wilson Moreira, Elizeth Cardoso and Jacob do Bandolim Lamartine Babo.

The best known of the samba, and those who are the most famous types are Bahia, Rio de Janeiro and what is samba .

Samba is influenced by Bahia and what is samba, in simple words, rapid and repetitive rhythms. Lambada, for example, is similar as it comes and Maxixe. However, the samba de roda that emerged in the nineteenth century Bahia, including Afro-Brazilian cultural elements. With cheers and chants, the dancers dance in a circle of people. The music is played by a band using guitar, conga, what is samba, tambourine and rattle.

In Rio de what is samba, samba is linked to life in the slums, and the words speak about urban life, workers and the difficulties of life in a nice way and often with humor.

In São Paulo, samba is influenced by the many cultures that have made the city their home, as with Italian influences, the lyrics are more sophisticated what is samba and is practiced by workers and humble people of what is samba Paulo.

For many children, so what is cyberbullying .the Internet is not just a convenient what is cyberbullying way to research or fun extracurricular activities - it's a large part of their social life. Emailing and chatting with friends are the most common activities online in children, what is cyberbullying after studying and playing games. But like many other social situations children bully other children online.

Cyberbullying is similar to other types of harassment, if it is not done online and through text messages sent to cell phones messages what is cyberbullying . Cyberbullies can be classmates, online dating, and even anonymous users, but most often they do not know their victims.

Some examples of ways kids bully what is cyberbullying online are
       * Sending someone mean or threatening e-mails, instant messages or text messages
       * Excluding someone from a list of IM contacts or block their e-mail for no reason
       * Deceive revealing personal or what is cyberbullying embarrassing information and send it to someone other
       * Breaking into an email or instant what is cyberbullying message account to send cruel or happen to someone making false messages that person
       * Creating websites to make fun of another person such as a classmate or a teacher
       * The use of websites to assess his peers as prettiest, ugliest, etc.

Children sometimes bully online and also bullying face-to-face, tend to do it in different ways. Children most commonly bully by sending messages of a sexual nature, or threatening to fight or hurt someone. Girls more often bully what is cyberbullying  by spreading rumors and sending messages mocking someone or exclude others. Also tell secrets. Victims of cyberbullying may experience many of the same effects as children who are bullied in person, such as a drop in grades, low self-esteem, a change in interest, what is cyberbullying or depression.

What is Open Source Software ?

We often heared about the programs open source Open-Source Soft for much deeper in this subject should read some books that talk about in detail, but in this article I try to explain that a little bit of this concept for the Arab rounded to the user.


Open source software programs are relevant Code Source or the source code is open and free, where anyone can take the original copy and modifies them whatever Haelaket makes its own version of the program.
Users can also open source software that used for any purpose, without restrictions or fees, and that trumps them all what he wants.


As an example of these programs, we find: Ubuntu Linux where it can be downloaded for free from the official website and the establishment of a large number of copies to your friends as you can enthroned in an unlimited number of computers. And thus can be downloaded to your source code and modify Ubuntu and making your own copy.

Unlike open source software, are closed source software (Closed-Source Software), which has a license and shut down its own source code and keep him out of users.
Firefox, Krouom, Android of the best examples of open source software, and is regarded as the default Windows caption and Office of months Amoelloukh source software.

Of the benefits of open source software it first often free. And secondly it's more flexible in use and as an example, we find, for example, in Aleuendwoz 8 new interface Metro is what distinguishes this version, but there are some users who Oahbu and the default Windows caption 8 but they did not crawl this interface and the program that folds must be closed source can not Nakhadd code source for the interface Aleuendwoz 7 and addressed to Oandwoz suitable for 8 and even tried one that will find it very difficult to do so. On the contrary, we find, for example, in the ubuntu if released a new version has not lived up fronted for users such as the issuance ubuntu gnome 3 where taking Almstkhadddhun source code for the interface Gnome 2 and Adloha to become compatible with the new version.
