Jakarta, PT Telkom Tbk membukukan 5,1 juta pelanggan Flexi hingga semester I 2007 ini. Namun demikian, jumlah tersebut tak bertahan lama karena sebagian kecil di antaranya telah dihapus oleh Telkom sendiri.Direktur Konsumer Telkom, Ermady Dahlan mengatakan, pihaknya telah menghapus 2% dari total pelanggan Flexi tersebut karena dinilai tidak memiliki data valid dan tidak produktif. Bila tidak dihapus, katanya, hanya akan mengakibatkan penggunaan kapasitas yang sia-sia."Kami sudah memverifikasi pelanggan kami terkait registrasi prabayar, dari total pelanggan tersebut, ternyata hanya 98% yang valid data-datanya, sehingga 2% di antaranya terpaksa kami hapus. Tapi sebelumnya kami sudah memberikan peringatan sebanyak 2-3 kali setiap bulannya," jelas dia usai peluncuran layanan prabayar Telkom Vision, di Gedung Telkom, Grha Citra Caraka, Jakarta, Kamis (26/7/2007).Dengan penghapusan tersebut, lanjutnya, pelanggan Flexi saat ini berkurang menjadi sekitar 5,04 juta pelanggan. Meski demikian, Ermady optimistis pelanggan Flexi akan mencapai angka 7 juta pelanggan hingga akhir 2007. "Sekurang-kurangnya kami yakin dapat mencapai 6,2 juta pelanggan," tambahnya.Ia mengungkapkan, dari total pelanggan Flexi saat ini, lebih dari 80% di antaranya merupakan pelanggan prabayar. Sementara sisanya, merupakan pelanggan pasca bayar, di mana kontribusi terbesar berasal dari pelanggan rumahan melalui layanan Flexi Home. (Dikutip dari Ditikinet)

Google Earth Enterprise Extends to Browser
Berita IT
Google is extending its Earth Enterprise into the second dimension, allowing users to view their organization’s geospatial data within a browser in 2D. “Organizations, such as an oil exploration company, depend on geospatial data to accomplish work. Many people in an organization need access to geospatial information, so allowing them to view 2D images in a browser, in addition to the downloadable Earth Enterprise client, provides more flexibility,” said Noah Doyle, product manager for Google Enterprise geospatial products.
The Google Maps API also now allows administrators to embed a 2D geospatial data into Web applications and to mash up with external spreadsheets and other data sources, according to Doyle.
For example, 2D data from Google Earth can be mashed up with Excel data on to view the geographical distribution of customers and their product preferences overlaid with manufacturing locations. Similarly, a real estate company could distribute 2D images of properties for sale and overlay data about them.
The Google Earth Enterprise service handles data integration and data streaming for companies that need a behind-the-firewall solution for integrating, manipulating and viewing their geospatial data. The downloadable Google Earth client handles 3D viewing, printing, annotating and data authoring. Pricing for Google Earth Enterprise starts at $20,000 and includes the new 2D viewing via the browser and mashup capability.
In addition, the new release of Google Earth Enterprise, which is a good example of consumer technology adapted for the enterprise, integrates with multiple search services, has improved security and is faster in vector processing and server response, according to the company.
While Google’s enterprise-oriented products are a very small fraction of the company’s revenue, the company is continuing to make progress with its search appliances and office applications. Given a few more years, Google’s enterprise division, which could include infrastructure-as-a-service offerings, will be more than a blip on the revenue statement.

NXP steps up research efforts for Wireless USB chips
Berita IT
NXP Semiconductors will invest £90 million (US$124 million) over the next five years to expand the development of Wireless USB products at its research and development (R&D) center in Singapore, the company said Tuesday.
NXP will spend that money to expand the number of researchers working on Wireless USB at the company's Asia Product Innovation Center (APIC), as well as fund those research efforts, said Mark Chisholm, a company spokesman, in an e-mail response to questions. The number of staff that NXP plans to add in Singapore was not immediately available.
"It will be a significant increase to the existing headcount," Chisholm said.
Wireless USB is based on ultra-wideband technology developed by the WiMedia Alliance. The short-range, high-speed networking technology aims to provide transfer speeds of up to 480M bits per second (bps) at a range of 3 meters, and up to 110M bps at 10 meters, although early products are somewhat slower.
NXP is one of the world's biggest providers of USB chips, and the development of those products is led by the company's team in Singapore, due to its geographical proximity to major customers in Asia. The Singapore team will also lead the company's Wireless USB efforts.
"APIC will collaborate with our USB team in the U.S. ... for some aspects of the development, but the majority of R&D will take place in Singapore," Chisholm said.

Intel fires fresh salvo at AMD in price war
Berita IT
The world's largest chip maker slashed prices on a handful of microprocessors after the company's battle to retake market share from rival Advanced Micro Devices Inc. (AMD) took a turn for the worse.
Intel Corp. appears to have undertaken some precision cutting in this round, re-pricing chips likely to catch attention, such as a quad-core microprocessor aimed at desktop PCs. The company slashed the price of the Q6600, a Core 2 Quad processor that runs at 2.4GHz, to US$266, down 50 percent, according to a new price list on Intel's Web site dated July 22.
The company also ventured where rival AMD dared not to when it reduced prices earlier this month, cutting prices on some processors aimed at laptop PCs. Intel reduced prices on two Celeron M processors by 20 percent each, a 1.73GHz Celeron that now sells for $107 and a 1.60GHz Celeron now reduced to $86 per chip. In servers, Intel slashed the price of its X3220 Xeon Server processor, which runs at 2.4GHz, to $266, down 50 percent. The price of the Xeon X3210, a 2.13GHz chip, was lowered 47 percent to $224 each. The prices are all for lots of 1,000 chips.
This round of price reductions by Intel was different than in prior quarters. The company lowered prices on fewer products, but it appeared to take aim more carefully. The difference may be in the fact its own profit margins have suffered during the pricing battles with rival AMD, or it could be in the fact that despite mounting losses, AMD was able to retake some market share from Intel in the second quarter.
Intel's main rival stopped a six month decline in market share during the second quarter, according to preliminary estimates from iSuppli Corp. AMD's market share climbed a half a percentage point in the second quarter to 11.4 percent, while Intel's fell by exactly the same amount to 80.3 percent, the industry researcher said.
"This ended a major resurgence in market-share during the prior two quarters for the microprocessor giant," iSuppli noted.
The price war has been painful for both companies. Stock market investors punished Intel after its second quarter earnings release because the company's gross margin failed to meet expectations. Intel's gross margin fell to 46.9 percent, but the chip maker forecast a rebound to 52 percent in the third quarter. Intel blamed lower average selling prices for the decline.
AMD has also been hurt. The chip maker reported a $600 million loss for the second quarter, which ended June 30. It was the company's third consecutive quarterly loss. AMD reduced prices on some of its microprocessors earlier this month.
The tit-for-tat price war Intel and AMD have fought over the past year has been great for users -- particularly in desktop PCs. Processors are the most expensive part of a PC, so price reductions on this key component really impact the overall cost of a system. Price reductions for microprocessors and other computer components are a natural part of the business. As products age, they lose value, so lower prices are used as a way to entice users to spend less on slightly older technology. But the market share battles between AMD and Intel in recent years have pushed both companies to boost technology and keep pricing down, to the benefit of users.

IEEE group settles on faster Ethernet plans
Berita IT
A technical group working on the next generation of Ethernet has agreed to disagree and will now work on a single standard that covers both 40G bps (bit-per-second) and 100G bps speeds.
The Higher Speed Study Group (HSSG), part of the IEEE (Institute of Electrical and Electronics Engineers Inc.), made the decision last week at its meeting in San Francisco after months of debate between backers of the two speeds. If the IEEE approves the move late this year as expected, a standard may be completed by mid-2010, said John D'Ambrosia, chair of the HSSG.
Ethernet has sped up by a multiple of ten several times, from 10M bps to 100M bps and ultimately from 1G bps to 10G bps, the current fastest version. Some HSSG members backed a similar boost this time and that 100G bps plan appeared to have won out late last year. But others pushed for a 40G bps standard.
Different applications were at the heart of the disagreement, according to D'Ambrosia. The need for speed is growing everywhere, but at different rates. While the data output of servers doubles roughly every 24 months, the amount of traffic on carrier networks is doubling every 18 months, according to D'Ambrosia. Members more interested in faster server-to-switch applications pushed for a 40G bps goal, while those aiming at network aggregation and backbones favored 100G bps. The higher speed means more expensive and power-hungry equipment.
"I wouldn't say there was a fight. I would say there was an education going on and it got heated at times," D'Ambrosia said.
Now a single standard, to be called IEEE 802.3ba, will include specifications for both speeds. Each will offer a selection of physical interfaces: There will be specifications for 40G bps links up to 1 meter long for switch backplanes, 10 meters for copper cable and 100 meters for multimode fiber. For 100G bps, the group will standardize 10-meter copper links, 100-meter multimode fiber links and 10-kilometer and 40-kilometer distances on single-mode fiber.
It's the first time an Ethernet standards task group has pursued two speeds in one standard, according to D'Ambrosia. "One size doesn't fit all, in this case," he said

Mobile broadband facing a revolution
Berita IT
Next-generation wireless technologies hold the promise of transforming the mobile broadband landscape, according analyst firm Frost & Sullivan.
Only a third of the world's population is connected to a cellular network, and wireless technologies such 3G Long Term Evolution (LTE), xMax and Mobile WiMax are set to make major inroads into the market.Current mobile WiMax standards are not yet optimised for mobile VoIP at vehicular speeds, so mobile WiMax will initially target the ultra mobile PC or tablet markets rather than the mobile smartphone market.But emerging technologies such as xMax will potentially enable service providers to promote unlimited local and long distant voice calls as well as unlimited text messages at very low monthly prices.XMax is considered by some to be the first 4G technology likely to be commercially available in 2008 and, once 3G LTE is a ratified standard, its performance characteristics will be superior to Mobile WiMax."A major portion of existing cellular networks would need a hardware upgrade to support 3G LTE," said Luke Thomas, programme manager at Frost & Sullivan."Service providers are still undecided as to whether they need to completely shut down circuit switched networks with the deployment of 3G LTE networks." These carriers are increasingly investigating the potential to sustain their profitability and boost average revenue per user (ARPU)."European carriers' dependence on voice to increase ARPU can no longer be a driving factor given the saturated market and various alternatives such as VoIP and reduced local and roaming call charges due to regulatory policies," said Thomas."As a result, carriers are now looking at various next-generation mobile broadband technologies to increase their ARPU in data applications and remain profitable in the long term."These long range, low cost wireless data transmission services are set to open up huge new markets for service providers in the future, according to the report, although they will require significant investment to fully reap the benefits.

Toshiba, Fujitsu, NEC Elec in talks to develop chips
Berita IT
Japan's Toshiba, Fujitsu and NEC Electronics, are in talks to jointly develop advanced 32-nanometre chips to better keep up with rivals, the three companies have said.
The companies aim to set up a joint venture to mass produce chips used in flat TVs and other high-power home electronics as early as 2010, with Toshiba expected to hold a leading non-majority share, the Nikkei business daily said the same day.The joint venture idea and other schemes have been discussed but nothing has been decided, the three companies said."If this is all that's being talked about, it's not enough," said Macquarie analyst Yoshihiro Shimada. "They need to spell out how they will work with technological standards being set by TSMC and IBM, and they need to start developing and manufacturing chips together now, not wait until 2010."Chip makers are racing to halve the production cost per function of a chip every year or two -- a trend known as Moore's Law, named after a co-founder of Intel Corp. Samsung Electronics, IBM, Chartered Semiconductor Manufacturing, Infineon Technologies and Freescale Semiconductor said in May they would work together on 32-nanometre chips. A nanometre is a billionth of a metre.STMicroelectronics, which on Tuesday said it plans to work with IBM to develop next-generation chips, may also join the group, according to Gary Patton, vice president of IBM's semiconductor research and development centre.Such moves have worried Japanese chip makers, which have been talking about but not acting on how to share the estimated 100-200 billion yen (US$830 million-US$1.66 billion) costs to develop the new chips, which would require less power to run more applications on cellphones, PCs and other electronics.Toshiba, NEC Electronics and Sony. had previously teamed up to develop chips with 45 nanometre features.Toshiba was the world's No.4 maker of chips in terms of revenue in 2006, NEC Electronics ranked No.11, while Fujitsu ranked 27th, according to research firm iSuppli.Shares of Toshiba were down 0.3 percent, while Fujitsu fell 1.3 percent and NEC Electronics dropped 1.7 percent at 0152 GMT, compared with Tokyo's electrical machinery subindex, which fell 1.64 percent.

Revolusi Chip “Punch Card”, 1 Terabit per Inci Persegi
Posted by Berital IT
Sejumlah peneliti IBM tengah mempersiapkan revolusi penyimpanan data pada skala terabit di atas keping chip yang tidak lebih besar dari sebuah perangko. Mereka menyebutnya dengan chip Millipede, yang menggunakan prinsip "punch card", atau jejak halus berukuran mikro untuk melambangkan satu bit data. Bagaimana cara kerjanya?
Peneliti IBM yang mengerjakan proyek ini berada di Zurich, Swiss. Mereka berhasil memanfaatkan "jejak" halus hasil indentasi pada permukaan chip yang bisa ditulis, dihapus, dan dibaca. Prototipe chip "1024 arms" telah mereka buat, ciptakan indentasi berukuran 40-nm menyilang. Chip tersebut memiliki kapasitas 200-GB per inci perseginya.
Nah, kini mereka sedang berjuang membikin piranti indentor "one arm" yang lebih kecil hingga bisa mencapai kapasitas hingga 1 terabit. Kapasitas sebesar itu setara dengan 10-15 kali kapasitas penyimpanan data chip yang ada saat ini. Satu terabit setara dengan informasi yang tersimpan dalam 200 CD.
"Teknolofi ini sangat potensial untuk aplikasi piranti bergerak semisal handheld," ungkap Peter Vettinger, pimpro Millipede. Karena kapisitasnya yang besar misalnya, piranti saku bisa menyimpan banyak album musik dalam format file MP3.
Prinsip Kerja Prinsip kerja penyimpanan memori "punch" ini sesungguhnya tidak terlalu rumit. Permukaan dari chip tersebut harus terdiri dari beberapa lapisan plexiglass di atas lempeng silikon. Menulis atau "writing" data membutuhkan pemanasan pada ujung indentor hingga 400? celcius. Hanya dengan temperatur setinggi ini saja jejak mikro bisa muncul di permukaan plexiglass.
Untuk membaca chip, indentor yang juga berperan sebagai sensor itu panasnya harus dikurangi menjadi 300? celcius. Nah, perubahan temperatur inilah yang diterjemahkan sebagai data.
Sukses dengan prototipe pertama, dikabarkan tim akan mengembangkan prototipe keduanya, chip dengan "4096 arms" yang akan rampung tahun depan. Menurut para penelitinya, penemuan mereka masih bersifat riset dan masih jauh untuk diimplementasikan.

Proteksi JavaScript Yahoo Otomatis Rubah Tampilan Kata
Posted by Berita IT
Untuk melindungi pengguna dari kode jahat yang mengincar komputer pengguna lewat kiriman e-mail, Yahoo menggunakan metode proteksi yang memanipulasi tampilan lewat JavaScript, beberapa pesan jadi tampil aneh.
Dengan proteksi tersebut maka mail server Yahoo akan secara otomatis mengganti beberapa jenis kata yang didapati dengan kata lainnya sebelum meneruskannya ke penerima. Hal itu dilakukan untuk melindungi penerima e-mail dan sistem milik Yahoo sendiri dari serangan kode jahat yang biasa diselipkan oleh hacker maupun terbawa oleh worm maupun virus. Akibat dari metode proteksi seperti itu tak jarang beberapa tampilan kalimat baik lewat e-mail maupun halaman situs yang diakses lewat Yahoo akan terbaca aneh.
Diantara sejumlah kata yang mendapat perhatian dan akan otomatis dirubah oleh Yahoo adalah "mocha" yang bakal ditampilkan menjadi "espresso".
