China may have hacked US satellites

Author admin    Category Hacking, IT News, Security     Tags

A US congressional commission has confirmed that hackers “interfered” with two government satellites between 2007-2008 via a Norwegian ground station.

According to Bloomberg, the Chinese military is suspected of executing the digital intrusions which targeted satellites used for earth climate and terrain observation.

China may have hacked US satellites

“Such interference poses numerous potential threats, particularly if achieved against satellites with more sensitive functions,” read a final draft report authored by the U.S.-China Economic and Security Review Commission.

“Access to a satellite’s controls could allow an attacker to damage or destroy the satellite. An attacker could also deny or degrade as well as forge or otherwise manipulate the satellite’s transmission.”

Indeed, a Landsat-7 earth observation satellite system experienced 12 or more minutes of interference in October 2007 and July 2008, while hackers tapped into a Terra AM-1 earth observation satellite twice, for two minutes in June 2008 and nine minutes in October that year.

Interestingly enough, the report doesn’t actually accuse the Chinese government of sponsoring or executing the four attacks.

However, it clearly states that the breaches are “consistent” with Beijing’s military doctrine which advocates disabling an enemy’s space systems, and particularly “ground-based infrastructure, such as satellite control facilities.”

In a conflict, the Chinese would try to “compromise, disrupt, deny, degrade, deceive or destroy” US space and computer systems, the draft claims, an act which could “critically disrupt the [the] military’s ability to deploy and operate during a military contingency.”

Sony Beli Saham Ericsson 1 Milyar Euro, Sony Ericsson Tinggal Sejarah

Author admin    Category IT News, Sony     Tags

Masih ingat dengan berita dari 24/7 Wall Stret Journal tentang 10 merek yang kemungkinan akan menghilang di tahun 2012 ? Ada nama Sony Ericsson di sana dan sepertinya prediksi tersebut akan menjadi kenyatan dengan sebuah press release yang menyatakan kalau Sony baru saja membeli seluruh saham Ericsson pada Sony Ericsson hari ini. Pembelian 50% saham tersebut akan memberika Ericsson uang cash senilai 1,05 milyar euro atau sekitar Rp 13 triliun.

Dengan pembelian ini, Sony akan memasukan smartphone sebagai salah satu senjata andalannya disamping produk tablet, laptop, dan konsol game. Perjanjian ini juga akan memberikan keuntungan bagi Sony dalam hal lisensi IP dan kepemilikan dari ”5 paten esensial” yang berkaitan dengan teknologi wireless. Pemisahan Sony dan Ericsson ini akan selesai pada Januari 2012 karena menunggu persetujuan dari regulator.

Berarti tidak akan ada lagi nama Sony Ericsson dan inilah kesempatan untuk penggemar Sony Ericsson untuk mengumpulkan berbagai produk SE sebagai koleksi sebelum berganti nama menjadi Sony.



Apple reportedly planting solar farm at datacenter

Author admin    Category Apple, IT News     Tags

Apple’s plans for iCloud datacenters in North Carolina have been shrouded in mystery for the most part since word broke out about them earlier this year.

The Maiden, N.C. site is reportedly being beefed up with a solar farm, according to The Charlotte Observer, based on permits Apple has secured to reshape the slope of part of the vacant land it owns.

Clues that point toward this assumption include an erosion control permit, notes about retaining soil moved “around the site from washing into creeks and other areas,” and multiple gravel roads for access to solar panels.

Naturally, Apple hasn’t announced anything publicly, and it is unlikely that it will anytime soon — if ever — before Apple files an actual building permit.

Nevertheless, it wouldn’t come as much of a surprise considering Apple’s firm stance on sustainable energy at its plants as well as eco-friendly components in its products. Reports about how much the Maiden location will cost vary between $500 million and $1 billion, and power for cooling systems and their respective servers are certainly going to cost big bucks.

Thus, an investment in solar energy such as this could save Apple more money (not to mention boost its greener image as a great PR move) in the long run.



Father of Artificial intelligence (AI) passes away at 84

Author admin    Category IT News     Tags

Artificial intelligence (AI) researcher John McCarthy has passed away at the age of 84.

McCarthy invented the computer language known as LISP, which uses symbolic expressions, rather than numbers, and was subsequently adopted as the programming language of choice for AI.

Father of AI passes away at 84

The researcher also coined the term “Artificial Intelligence” in 1955 for the first Dartmouth conference.

“I came up with the name when I had to write the proposal to get research support for the conference from the Rockefeller Foundation,” he told CNET back in 2006.

“And to tell you the truth, the reason for the name is, I was thinking about the participants rather than the funder.”

McCarthy firmly believed that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.

“If a machine can do a job, then an automatic calculator can be programmed to simulate the machine,” he wrote in a 1955 research proposal on the topic

“The speeds and memory capacities of present computers may be insufficient to simulate many of the higher functions of the human brain, but the major obstacle is not lack of machine capacity, but our inability to write programs taking full advantage of what we have.”

Noel Sharkey, Professor of Artificial Intelligence at the University of Sheffield, told the BBC that McCarthy was “foundational” in the creation of the discipline of Artificial Intelligence.

“John McCarthy’s main contribution to AI was his founding of the field of knowledge representation and reasoning, which was the main focus of his research over the last 50 years,” said Sharkey.

“He believed that this was the best approach to developing intelligent machines and was disappointed by the way the field seemed to have turned into high speed search on very large databases.”

Author admin    Category IT News, Twitter     Tags

Selama ini untuk berkomunikasi melalui Twitter yang bersifat personal hanya bisa melalui Direct Message. Untuk Teknokerz yang menginginkan pilihan lain selain Direct Message, kini hadir pesan instan dengan konsep mirip Facebook bernama Bonfire.

Bonfire diklaim akan mengubah pengalaman Teknokerz dalam hal bertwitter-ria. Kita dapat berkomunikasi secara personal melalui ruang chat yang akan hadir pada bagian bawah halaman website, sama halnya dengan konsep ruang chat pada Facebook. Selain itu kita juga dapat mengetahui apabila teman kita sedang online. Bonfire yang dirilis mulai hari ini juga memiliki plug in untuk Chrome dan Safari, tentu nilai plus inilah yang diharapkan pihak Bonfire untuk bekerja sama dengan Twitter.

Bonfire sendiri beroperasi dengan cara mendeteksi browser yang kita pakai, dan secara otomatis menyuguhkan plug in yang sesuai. Setelah terinstall, kita dapat berchatting-ria dengan teman di Twitter, tanpa harus ‘mention’ teman dan membanjiri lini masa/timeline. Untuk berkomunikasi, pengguna harus di-follow, dan me-follow balik pengguna tersebut.

Teknokerz tertarik pada Bonfire?

Linux kernel 3.1

In May Linux finally saw the release of kernel version 3.0, an evolutionary update to the popular open-source platform that was nearly 15 years in the making. Today, version 3.1 is making its debut, once again primarily offering small tweaks like better support for Intel’s Ivy Bridge and Cedar Trail chips and improved power management. But there are some new features getting baked in, including support for NFC and drivers for Wiimotes. The brave amongst you can download the sources from Git now (it hasn’t been posted to just yet), but we suggest you hold out until your distro of choice releases an official update.



Worldwide, Broadband demand & speeds are zooming

Author admin    Category IT News     Tags

Netherlands, one of the most progressive countries when it comes to broadband has now become a nation with the highest broadband connectivity, according to Akamai’s The State of the Internet report for the second quarter of 2011. Akamai data shows that the unrelenting march of broadband continues unabated all across our planet. Not only are the number of broadband subscribers on the up, but so are the average speeds.

Akamai reports are based on connections to Akamai’s global network from both wired and wireless networks. The data collected by Akamai shows that nearly 27 percent of all connections to Akamai’s network are at speeds in excess of 5 megabits per second (Mbps.) Nearly 68 percent of broadband connections in Netherlands exceed 5 Mbps. Hong Kong and South Korea are next with 59 percent and 58 percent.

  • Europe dominates the list of top ten countries with the highest broadband connectivity.
  • However, Asian cities dominate the list 100 fastest cities in the world, with Japan alone having 59 cities and 10 South Korean cities.
  • Brno of Czech Republic is the fastest ranked city in Europe and is only ranked #55.
  • Eighteen US cities are on the top 100 list with San Jose being the fastest -ranked 9 out of 100. Average speed in San Jose was 13.7 Mbps. San Jose also had the highest peak speed in the US of 38.7 Mbps.
  • South Korean city of Taegu is the fastest city in the world with average Mbps of 15.8 Mbps. South Korea’s Taejon had the highest peak speed of 55.3 Mbps.

Global broadband speeds are getting faster and faster, the data reveals.

  • After growing nearly 10% in the first quarter of 2011, the global average connection speed once again saw another significant quarterly increase, growing 21% to 2.6 mbps.
  • Global average connection speed grew significantly year- over-year as well, increasing 43%.
  • Globally, year-over-year increases in average connection speed were seen in 128 countries/regions, with yearly growth of over 100% seen in 17 countries, while an additional 102 grew 10% or more over the prior year.
  • Global peak speed was 11.4 Mbps, up 7.4 percent from the first quarter of 2011 and 67 percent from Q2 2010.
  • US which is ranked 12th by average measured connection speed had an average speed of 5.8 Mbps, up 9 percent from the first quarter of 2011 and a whopping 26 percent from Q2 2010. The availability of higher speed tiers (30 Mbps or higher) from cable companies is behind this boost.

The biggest growth has been on the mobile networks according to Akamai’s data.

  • Average measured connection speed for known mobile providers worldwide ranged from a high of slightly more than 5 Mbps to a low of 209 kbps.
  • Approximately three-quarters of the surveyed providers had average connection speeds above 1 Mbps.
  • For the 108 mobile providers worldwide for which Akamai analyzed data, three boasted average peak connection speeds above 20 Mbps, 27 achieved average peak connection speeds above 10 Mbps and 47 recorded average peak connection speeds greater than 5 Mbps. Only one mobile provider (located in South Africa) did not record an average peak connection speed above 2 Mbps.
  • Users at 74 of the surveyed providers consumed greater than 100 MB per month of content from Akamai. According to Ericsson, the volume of mobile data traffic in the second quarter of 2011 doubled year-over-year and grew eight percent quarter-over-quarter.



A Quick Android 4.0 Ice Cream Sandwich Feature

Author admin    Category Android, IT News     Tags

While hardware junkies like myself may have spent the past few weeks drooling over the Galaxy Nexus, the onstage demo of Android 4.0 Ice Cream Sandwich proves that the software powering the device is just as impressive (if not a little moreso).

Our hands-on with the Galaxy Nexus and Ice Cream Sandwich will be coming shortly, but here’s a quick rundown of what Android 4.0 will be bringing to the table come November.

  • Roboto: Goodbye Droid Sans, a new typeface called Roboto is here to rule the roost.
  • Landscape Controls: We knew that the Galaxy Nexus opted to move the classic Android buttons onto the screen, but they smartly disappear when viewing video or in widescreen mode.
  • Flexible Widgets: Ice Cream Sandwich’s stock widgets are resizable and more robust than previous versions. They also now occupy their own separate space in the app drawer.
  • Folders: Dragging apps and contacts on top of each other create re-arrangeable folders a la iOS.
  • Favorites Tray: Users can stow their favorite apps, links, and folders into a new Favorites tray for quick and easy access.
  • Taking Screenshots: This one has been a long time coming. Hold down the power button and the volume down button to snap a screenshot.
  • Notifications: Hefty revamp here, as the contents are much more customizable. Music controls have been integrated, and notifications are also easily dismissed with a quick swipe left or right.
  • Improved Copy & Paste: Copying and pasting content is made much easier, as you can now move around entire blocks of text. Very useful.
  • Face Unlock: One of the most ambitious is Ice Cream Sandwich’s new Face Unlock feature, which allows users to unlock their handsets just by looking into the front-facing camera.
  • Enhanced Talk-to-Text: Voice input seems much smarter this time around, as it’s more accurate, requires less time, and even accounts for pauses.
  • Browser: The stock browser now sports tabs, and it maxes out at 16. Web pages can now also be saved offline for later perusal, and users can directly request the desktop version of a site.
  • Gmail: Gmail now supports two-line previews, and sports a new context-sensitive action bar at the bottom of the screen. Gesture support allows you to swipe left and right between emails.
  • People App: A new spin on the contact list. The phone’s owner has their own profile, and people’s contact details are sourced from Google+, Facebook, Twitter, etc. Users can define favorite contacts, and individual people can be placed on the homescreen or in folders for quick access.
  • Calendar: Features a redesigned UI and includes pinch-to-zoom to vary the level of detail on a calendar page.
  • Data Usage: Users can now drill down into their data usage over a certain period of time, including the ability to see which apps are the biggest data hogs and the ability to limit data usage to a certain threshold.
  • Camera: There’s a lot to love here. It features image stabilization, improved autofocus, and integration with other apps for sending photos or instant upload to Google+. Oh, and who could forget built-in face detection, panorama and time lapse modes, and on-the-fly photo retouching and enhancements.
  • Android Beam: An secure NFC-powered sharing platform that lets users share nearly any kind of content, save for applications (in that case, a link to the Market is sent instead)



Video Promo Galaxy Nexus Officially Announced

Author admin    Category Android, IT News     Tags

There’s still half an hour to go until the Galaxy Nexus officially takes the stage in Hong Kong, but the official spec sheet has already begun to make the rounds.

The Galaxy Nexus is, of course, the first device to run Android 4.0 Ice Cream Sandwich, but the spec sheet has confirmed a few nifty features we were hoping would make the final cut.

One long-awaited example is the ability to take screenshots by holding down the power and volume down buttons. The device also adds support for a novel “face unlock” feature that (what else?) allows users to gain access to their handsets just by flashing their pearly whites. The new People app also makes an appearance, complete with Google+ integration. The notification and multitasking systems have also been revamped to allow for quicker info and app management.

As far as hardware goes, the Galaxy Nexus is set to impress. It packs a 4.65-inch Super AMOLED display running at 1280×720, 1GB of RAM, and a 1.2 GHz dual-core processor. Sorry folks, no word on the exact make of the processor, but the night still is still young and someone is bound to give out details sooner or later. The Galaxy Nexus indeed sports an NFC chip, as well as either an LTE or HSPA+ radio depending on your particular locale. It’s also being reported that the device will come in both 16 and 32GB variants, which likely won’t do much to appease those in search of microSD card slots.

For better or worse, the 5MP camera that was hinted at in an earlier leak has been confirmed, although Samsung mentions that the camera will take photos with virtually no shutter lag. On the flip side, users will find a 1.3MP front-facing camera ready that’s ready for a bit of face time. Samsung has managed to squeeze all of that into a body that’s just 8.94mm thick — not quite Droid RAZR territory, but impressive nonetheless.

The Galaxy Nexus is due to launch early November in the United States, Europe, and Asia.
