Pengenalan PHP

Data umum boleh diakses oleh semua pihak. Untuk membuat website yang dinamis dan mudah diupdate setiap saat dari browser, dibutuhkan sebuah program yang mampu mengolah data dari komputer klien atau dari komputer server itu sendiri sehingga mudah dan nyaman disajikan di browser. Salah satu program yang dapat dijalankan di server dan cukup andal adalah PHP. PHP adalah salah satu bahasa pemrograman yang berjalan dalam sebuah web server dan berfungsi sebagai pengolah data pada sebuah server. Dengan menggunakan program PHP, sebuah website akan lebih interaktif dan dinamis. Data yang dikirim oleh pengunjung website/komputer klien akan diolah dan disimpan pada database web server dan dapat ditampilkan kembali apabila diakses. Untuk menjalankan kode-kode PHP ini, file harus diupload ke dalam server.


Mengapa menggunakan PHP?
Pemrograman yang berjalan di server banyak sekali. Setiap program mempunyai kelebihan dan kekurangan. Saat ini banyak website yang menggunakan program PHP sebagai dasar pengolahan data. Beberapa keunggulan yang dimiliki program PHP adalah :
- PHP memiliki tingkat akses yang lebih cepat.
- PHP memiliki tingkat lifecycle yang cepat sehingga selalu mengikuti perkembangan teknologi internet.
- PHP memiliki tingkat keamanan tinggi.
- PHP mampu berjalan di beberapa server yang ada, misalnya Apache, Microsoft IIS, PWS, AOLServer, phttpd dan Xitami.
- PHP mampu berjalan di linux sebagai platform sistem operasi utama bagi PHP, namun juga dapat berjalan di FreeBSD,Unix, Solaris, Windows dan yang lain.
- PHP juga mendukung akses ke beberapa database yang sudah ada, baik yang bersifat free ataupun komersial. Database itu antara lain MySQL, PostgreSQL, mSQL,Informix, dan MicrosoftSQL server.
- PHP bersifat free atau gratis.

Southridge Capital Management

Southridge Capital Management
Required a courage in investing, not only that, the necessary experience, expertise and planning before taking action to make decisions and is a very large capital if we want the expected results.

Investments in technology, medicine / healthcare is an option that can provide a promising prospect. As performed by Southridge Partners II. This is a positive step from the policies made by the southridge advisors.

Stephen Hicks, Chairman and CEO of Southridge, LLC (“Southridge”), today announced that Southridge Partners II, an institutional investor, has entered into a $10 million equity purchase agreement with TechniScan, Inc. (OTC BB: TSNI), a medical device company engaged in the development and commercialization of an automated 3D breast ultrasound imaging system.

TechniScan Medical Systems is a public medical device company engaged in the development and commercialization of automated ultrasound imaging systems. TechniScan automated imaging system is designed to assist clinicians in 3D breast imaging.

We are excited to be TechniScan’s equity investor in this major phase of developing better breast cancer diagnostics,” said Mr. Hicks. “Southridge is committed to working with TechniScan in the vital research of this emerging technology.”

Pursuant to a purchase agreement, TechniScan has the right, at its discretion, to sell to Southridge up to $10 million of its common stock over a 24-month period. The Company will have the right, but is not obligated, to sell stock to Southridge depending on certain conditions as set forth in the purchase agreement.

Modern Diesel Engine Maintenance ( Common Rail Technology )

The use of biodiesel fuel for modern diesel engines can still be tolerated. But a consequence, regular maintenance should be a serious concern. That is because the quality of bio-diesel on the market very vulnerable to contamination by water, dirt, high sulfur content. It can directly interfere with or even damage the common rail work.

When initiating service, the most important is to drain the fuel tank and replace the diesel filter. Drain the tank and the replacement of diesel filters is varied depending on the manufacturer's recommendations. However, car owners may have relied on the guide service. Replacement of diesel fuel filter and drain the fuel tank can be done more quickly, or half of the mile by a guide service.

It is easy to calculate. If a guide is recommended for your service to drain the fuel tank and replace the diesel every 20,000 miles, if you use biodiesel, you should drain the fuel tank and replace the fuel filter every 10000-15000 miles.

Periodic maintenance is faster, because the two places where the most vulnerable to water, dirt and sulfur buildup. Dirty diesel fuel filter will make a heap of dirt get into the injector, causing damage to the injector.

By doing a diesel fuel tank drain and replace diesel fuel filter every routine servicing, to minimize dirt, water and sulfur settles longer. Automatically, the possibility of common rail devices contaminated with dirt, water and sulfur are smaller and tools common rail has a longer service life.

Alternative Energy

The energy that we often use more and more reduced or depleted. Because of the wide use of uncontrolled, giving rise to the scarcity or even die out. For that now needs to consider the alternative energy instead of energy which is usually often used. The following are the various alternative energy sources that can be utilized, in addition will help the air to be clean, the savings also will be done.

Wind. Kinetic wind power is now already widely used as a wind player using wind turbines for home or for business purposes. Just one turbine can support up to thirty houses, but because the wind is always blowing, backup power must always remain available.

Sun. Sun-rich tropical countries seem to be very suitable to use this resource. Try using a roof made of solar systems are called photovoltaic cells.

Biodiesel. The basic ingredients of this fuel made from plants like soy, coconut and the like, biodiesel is non-toxic fuel that can be blended with regular diesel or used as is to reduce emissions.

Nuclear. With uranium fuel, metals found in rocks, and processed in a nuclear reactor, the heat energy will be used as an ingredient to turn turbines that exist. These energy sources do not release greenhouse gas emissions. 20% of the power source in the U.S. have nuclear fuel.

Hydrogen. How do you create a resource that did not remove anything but clean water? The answer is hydrogen fuel cells. The problem now is to separate hydrogen from a composition, such as carbon chain or water, means using other resources. Storage of hydrogen is also not easy, because its density is very low, it is very difficult to put hydrogen in large quantities in a narrow room. Hence, although many vehicles began using hydrogen as fuel, it is still difficult to set up hydrogen filling stations.

The difference between analog and digital?

Digital
As a technology, analog is the process of taking an audio or video signal (human voice), and translated into electronic impulses. Violation of the second digital signal into a binary format where the audio or video data represents a series of "1" s and "0" s. Quite simply, if the device is an analog or digital telephone, fax, modem, or wise, that not all the converting for you.

Digital vs analog indicate that the method of input, data storage and transfer operation of the internal device, and the nature of the display. The word comes from the same source as the word and the number DIGITUS.
The digital technology breaks your voice (or television) signal is a series of binary 1 and 0 at the other side, where another device (phone, modem or TV) takes all the numbers and putting them in the original signal. The beauty of digital that he knows what must be, if at the end of your transmission. Thus, if a fault occurred in the data transfer. What does this mean for you? Clarity. In most cases you'll get distortion-free conversations and clearer television images. The nature of digital technology makes it possible to cram together many of those 1 and 0 in the same space an analog signal. As a button-rich phone at work or in the 200-plus digital cable service, means that multiple functions crammed into a digital signal. Digital offers better clarity, but analog gives a richer quality. Like a digital VCR or CD is the cost of everything from cell phones coming out and the satellite dishes.

Telephone lines

The digital telephone lines are big business. Though digital lines carry lower voltages than analog lines, still pose a risk to the analog equipment.

The analog lines are also known as POTS (Plain Old Telephone Service), support standard phones, fax machines and modems. These lines, which are characteristic of your home or small office

There are digital-analog adapters that not only allows you to use the analog devices in the digital environment, but also protection against frying the internal circuits of the telephone, fax, modem or laptop.

Cordless Phone

The nature of digital technology, breaking the mark of a binary code and recreating the host endgives it clean, distortion-free wireless calls.

Cordless phones, digital technology is able to encrypt every 1 and 0 during the transfer, so the conversations secure from eavesdropping. Plus, more power can be applied to digital signals, so you will have a wider range of wireless phone conversations to enjoy.

The advantage of the analog cordless products? Well, they are a bit cheaper. And the sound quality is richer. So, if the digital security, why not save a few bucks and go with an analog phone line? Indeed, in the home or small office environments where you may be the only wireless user, you will not be disturbed.

Keep in mind when talking about the digital and analog cordless phones, talking about the transmission of signals between the handset and the base. The phones themselves are analog devices, which are exclusively on analog lines. The range of analog or digital wireless phone is always willing to depend on the environment.

Cell Phones

Perhaps the most effective against the analogue to digital technology in the growing mobile market. Activate the new phone is growing exponentially, quickly realized the limits of the analog.

Digital cellular lets significantly more people use their phones to a coverage area. Further information is transmitted and received simultaneously on all telephone users. Plus, transmissions are more resistant to static and signal fade. And the all-in-one nowphone phones, pagers, voice mail, internet access, digital phones with more features than the analog predecessors.

The analog sound quality, some users still superioras dual transfer switch in the right-hand phones with analog sound, when not busy with a full coverage areabut digital is quickly becoming the standard in the mobile market.

Better sound
Digital provides better sound quality. Supporters of digital claimed too that because digital scrambled up the signal bursts, it is more secure than analog and can help to thwart "cloning" an act of grabbing phone account information over the air, and then copy the sales data for the purposes of piracy. Some industry estimates, nearly $ 650 million in wireless services to their large ears coveted criminals, adding that the bottom line of the operating costs are eventually transferred to the buyer. Digital battery is stronger than analogue, and most, better, more advanced phone services.
