AMD vs Intel: Resistance A Tough Processors

0 komentar
Inevitably, the processor market competition more recently heated up with two camps as a major player competition, which Intel has long dominated the market and AMD has recently launched many products that work performance is threatening the dominance of Intel.

Impartially on the Intel and AMD, and let you know as a consumer, the tough competition these companies to dominate the market from one season to the next does not always make a product from one company to be better than other company's products and vice versa.

Actually it would be better if it had a third option, but unfortunately all the technology

As we know now, Intel dominates the processor market, both in terms of price, performance, and of course in terms of quality assurance. Of course this opinion arises regardless of AMD in it.

So far, AMD has been slow in handling the 'rigidity' in technology development, slipping the launch date of AMD may have caused death in the face of competing measures, and the results that have made AMD's $ 5 billion owed to the ATI at the beginning of this year.

AMD 690G chipset is one famous example of success, and if Intel has taught us anything, it's all the way to generalize the chipset dominance in the PC market. AMD did not fall asleep in the wheel rotation processor technology. Maybe a lot of late, but not dead. Currently AMD has prepared a powerful processor called 'K10', and a processor improvement of 'Barcelona'. Not much is known about the performance of AMD's desktop processors to come (K10 Phenom X2 and X4) now, but we must find out quickly whether 'Agena' and 'Kuma' this will make Intel a loss.

While many successful AMD products lately, it will be a lot of his colleagues who follow him, while ensuring that the success of Intel Core 2 Duo processors will be perfect design for a future chipset. As they say, "This is the name chipset".

Intel Core 2 Duo is a very efficient processor, the value of the TDP (Thermal Design Power) is only about half of which used a series of Pentium 4 / D, and in actual usage tests showed that the computer systems that use Intel Core 2 Duo did save a lot energy.

That all is good, this is lifted Intel not because the velocity within a few points, but because the Core 2 Duo is much faster and very competitive price. Perhaps the value of a processor is still often we look so far. To remember is that although Intel's Extreme Edition are still highly valued, but still considered very reasonable for a desktop CPU innovation. Compare with AMD processors with relatively the same price, Intel would still be on it.

So, as already discussed above, actually When does the time for AMD or Intel? Intel still wins this round. The point is that the maneuvers are still exceeds AMD Intel, also a whole generation of multiple processors available. Performance Core 2 Duo is very satisfactory, which is why many recommend it.

But before closing this discussion, there is one more thing to remember. Throughout our comparison based on brand loyalty and performance test only, then there would not be much of a choice of the latest technology and best. The most important thing now is if you use the computer now able to meet all your computing needs, then you no longer need to bother choosing between Intel and AMD. (Dna) Transmeta best of disputed legitimacy of his intellectual property. Still just about the energy savings that are considered more important in any comparison of the performance of day to day.

Maybe this is the super-powerful notebook that Apple ever offered in its history. MacBook notebook at a low price is inspired from the ultra-thin laptop brand Hewlett-Packard and Asus, which dibandrol prices range between $ 600 to $ 900.

So what's different with Apple MacBook laptops this?

Existence processor ULV (Ultra Low Voltage) from Intel such as SU4100 or SU7300. Both processors are a power laptoplaptop white MacBook 13-inch polycarbonate is used high performance Intel processors in up to 5 hours.
The latest MacBook and will support the extra battery life, which claimed Apple could last up to 10 hours. As for performance

This may be an opportunity for Apple to enter the low cost laptop segment, prior to the media plus the netbook market next year pad. Although the price of the MacBook Air earlier reached $ 1,500, and the MacBook Pro reaches $ 1,199, the new Apple MacBook will dibandrol for less than $ 999.
Meanwhile, AMD processor could be eliminated forever from the MacBook? AMD's own laptop is now focused on ultra-thin dual-core processors with MSI's ATI graphics, with prices starting at $ 500, cheap enough price for a netbook.

Masalah Potensial Keamanan iPhone

0 komentar

iPhone sebagai produk keluaran terbaru dari Apple telah banyak mengundang perhatian para hacker untuk mencobai keamanannya. Yang unik dari iPhone adalah bahwa produk ini tidak dilengkapi dengan software pengaman. Namun di lain pihak, Apple juga tidak mengijinkan pemakai iPhone untuk menambahkan software pengaman sebagai langkah antisipasi untuk menghindarkan iPhone dari infeksi virus-virus software. Namun saat iPhone terhubung ke Internet, kemungkinan tersebut tetap saja terbuka, kata Marius van Oers, seorang peneliti security dari McAfee's AVERT Labs di Amsterdam. Dia sendiri tidak mau menyebutkan secara spesifik celah keamanan yang dimaksud, namun dia menyebutkan beberapa cara untuk menemukan jalan masuknya.

Apple sendiri bergantung pada pengembang dalam menciptakan aplikasi Web-based yang akan diakses secara langsung menggunakan Safari Web Browser. Menurut Oers, browser Safari ini sendiri diklaim mempunyai kelemahan yang dapat membuat hacker mendapatkan kode ilegal dari sistem yang sedang berjalan.

Masih menurut Oers, “Adalah wajar bagi seseorang untuk berkirim SMS maupun email dengan menggunakan link web. Dan sekali terkoneksi dengan link web tertentu, server dapat menyusupkan kode ke dalam iPhone, jika sekali saja hal ini terjadi maka kendali Anda akan segera berpindah”.

Hal yang terjadi pada browser Safari tersebut ditemukan oleh Independent Security Evaluators, sebuah perusahaan yang hadir pada Konferensi Keamanan Black Hat bulan Agustus yang lalu. Dari sebuah situs, para peneliti memasukkan kode ke dalam iPhone dan menyerobot pesan text, nomor telepon serta email terbaru yang masuk. Sejak saat itu Apple memperbaiki kekurangannya tersebut.

Oers memaparkan pandangannya mengenai iPhone ini pada Virus Bulletin Security di Vienna. Apple juga mengjinkan pemakaian Javascript pada saat iPhone terhubung ke Internet. Lebih lanjut, aplikasi multimedia Apple, QuickTime juga cenderung mempunyai kelemahan dalam konsep eksploitasi web.

Namun begitu, iPhone tetap populer di pasar Amerika dan Eropa dalam 6 minggu terakhir ini, sehingga Apple mungkin dapat mengharapkan lebih banyak campur tangan hacker untuk mengganggunya.

Hacker yang mengganggu ke dalam sebuah peralatan memang relatif lebih sedikit dibandingkan dengan yang mengganggu sistem komputer desktop. Namun beberapa aplikasi hacker kini telah dibuat untuk peralatan mobile, termasuk diantaranya untuk menghubungi ulang nomor telepon atau mengirim text ke nomor-nomor telepon milik hacker yang mendapatkan penghasilan darinya.

Mungkin kesempatan para hacker saat ini kecil, namun di masa yang akan datang kesempatan seperti itu bukan tidak mungkin akan meningkat, walaupun kita semua tidak mengharapkannya.(dna)

Internet applications for the Blind

0 komentar
People who suffered blindness in his eyes, when he will be using computers in general is assisted by a screen-reader software. But to buy a screen-reader software cost is quite expensive, about more than USD 1000, so sometimes they can not sit like a normal person in a library or Internet cafe (cafe). Now, a program with the latest web base will help the blind people to change the situation.

Programs on the web is called WebAnywhere. WebAnywhere was developed by computer science graduate student from the University of Washington, Jeffrey Bigham. Unlike other software to be installed on PCs, WebAnywhere is an Internet application that can make the Web accessible to people who are blind.
Bigham hopes that the people who are blind will be able to check flight departure time on the computer Airport, planned to take a bus to a desired route through the computer in the library, or typing a quick email over the Internet. To get WebAnywhere, people who are blind should be set to online, which will collide with mugkin computer is not ready to give verbal feedback again. However, Bigham found in his research, that WebAnywhere, specifically used by blind people, would know the keyboard tricks and when to ask for help.

Once WebAnywhere online via the Internet, people who are blind can surf using WebAnywhere browser, which can be connected to the web page and then voiced content of the article in these pages with hard, as long as computer has speakers or headphones. WebAnywhere program can also jump section titles, tab, charts or read the page from top to bottom.

Lindsay Yazzolino, coed 19-year-old blind man from Brown University, who worked part time at the University of Washington, revealed that a large improvised WebAnywhere is the total lack of public access for this. Yazzolino, very pleased with the features and some WebAnywhere owned keystroke navigation pages in it, mainly because the program is free WebAnywhere used.
Bigham expect others to make improvised WebAnywhere program, by making it as open source that will invite people who like to play with the code and open to programmers from anywhere. Richard Ladner, a professor of computer science faculty of the University of Washington, want a commercial search engine will adopt WebAnywhere module, and one day hopes Ladner, also blind people can design their own web pages.
