SIG representatives argue that new modules can provide data rates up to 24 Mbps (ie eight times more abundant now, Bluetooth 2.1 + EDR), with the battery module, fed with the standard battery type CR 2025, can reach to several years. Range is 100 meters and more. It is also reported to increase security when transmitting data through the use of protocol encryption AES 128-bit key.

Through the application of new energy technologies, Bluetooth 4.0 modules can be implemented in low-power devices with low power. Thus, it becomes possible to use them in electronic devices in various spheres, including medicine, entertainment, sports, safety, and others.

All team members will be able to live Bluetooth SIG acquainted with devices equipped with Bluetooth technology modules fourth version of the conference, which is scheduled to start on October 4 this year. It is expected that upon closing, device manufacturers can begin active implementation of a new type of communication modules in their own products.

Washington is working on the defense program, Perfect Citizen

July 18th, 2010 admin Posted in News | No Comments »

Wall Street Journal reports that the U.S. federal government is working on the defense program, known as the Perfect Citizen technology. The objective is to create a means of detection of cyber attacks on private companies and government agencies that control critical infrastructure such as electricity, nuclear power, chemical and biological industries, and t n.

Supervises the draft U.S. National Security Agency. Now running the NSA is already in the lion’s share of the government and military networks of the U.S. technology. The new project is planned to create interfaces for the partial merger of government and corporate networks and on all the networks put the sensors, which will fulfill the role of early detection of attacks. The sensors will continuously monitor the state of networks and listen to them for “atypical” activity. Through such “points of interaction, can be avoided the need to monitor all networks at once, at a cost of enormous resources.

Sources familiar with the implementation of the program, said that recently an American defense contractor Raytheon Corp won a government tender closed at $100 million. Now the company to design a monitoring system to protect against hacker attacks. Implement a system will most likely other contractors. From the official comments so far and representatives of the NSA and Raytheon refused, wrote CyberSecurity.

However, WSJ notes that the program in its current form quite flawed and American business is not burning with desire to take part in it, believing that Perfect Citizen – this is another attempt of intrusion “Uncle Sam” in the privacy of companies and citizens. There are, however, and the company that called the program an important and say they are ready to cooperate. Sources in the WSJ Raytheon argued that the system is constructed so that the government simply wants to ensure the security and critical infrastructure to get into the personal affairs of the companies it did not intend.

Independent military experts in Washington say that the need for the program has long been evident, and the probability of invasion of privacy is comparable with the probability of invasion of privacy from the outdoor surveillance cameras, which had been long established in the city streets. “This (program) is a logical extension of the federal agencies, done in the past to protect critical infrastructure” – said in Washington.

In this case, an unnamed military official said that while the system is still very far from complete, and even in the States at the level of the federal government has no common vision and understanding of the system.

This malware is a script that is added to the Web page and automatically redirect visitors to infected sites. After this occurs downloading and execution of malicious code on vulnerable computers. This threat, known as specialists ESET as JS / TrojanDownloader.Pegel.BR, distributed throughout Europe very rapidly. As a percentage equivalent to the total number of infected computers, its share is already 2.29%, which ensured Troyan fifth place in the world ranking of threats. Despite the fact that malware JS / TrojanDownloader.Pegel.BR had not yet spread in Ukraine, experts strongly recommend ESET Ukrainian users to be extremely careful when downloading files from the Internet network.

In June, the family Conficker continues to be active. Win32/Conficker which holds monthly palm among malicious software in the world (9,79%) and Ukrainian (19.42%) ratings of threats. This worm spreads through the vulnerability of Windows, which is located in the subsystem RPC (RPC), as well as through unprotected public folders and removable media. Also widespread is the threat of INF / Conficker – another representative of the famous family. Using the file autorun.inf, this malware is circulating last variation Conficker worm to infect PCs. A large number of infected computers around the world and in Ukraine, including (1,47% 1,66%, respectively, and) provides this threat lidiruschie positions in ratings of malware.

Experts strongly recommend ESET users to reliably protect personal data, because they do not concede its position such threats as Win32/Agent, Win32/PSW.OnLineGames and Win32/Tifaut, designed to steal confidential information. Users should also beware of malware INF / Autorun, which uses the opportunity to autorun on removable storage media and runs malicious code every time you connect a removable storage media to the computer, as well as “novelty” of last month – Win32/Sality, predstavlyauschuyu a polymorphic virus that modifies the EXE and SCR files and disables antivirus programs.

The beginning of summer could not “please” users with new viruses. In the top-10 world ranking of threats in June, presented two “novelties» – Win32/Qhost (1,16%), and HTML / ScrInject.B (0,84%). Trojan Win32/Qhost distributed via e-mail and gives hackers access to infected computers. Before starting this threat copies itself to the folder Windows% system32%, and then modifies the host file to redirect traffic to the domains of the attacker. The threat of HTML / ScrInject.B detects HTML web pages with confusing scripts or IFRAME tag, which automatically redirect to malicious software downloads.

Motherboard ASUS Crosshair IV Formula chipset AMD 890FX

July 5th, 2010 admin Posted in Computer Hardware | 1 Comment »

Issue-One “Southbridge” AMD SB850 allowed the company to upgrade the entire line of chipsets. Upgrading is a modification of the seventh family (770, 780G, 790GX, 790FX), which resulted in the light of an eighth – 870, 880G, 890GX, 890FX. And if the “north bridge” with integrated graphics core, AMD engineers have something to do, the creative freedom for discrete chipsets, they have proved very little. However, nothing is perfect, and some work on the bridge 890FX still were. Surely the developers with some of the shortcomings 790FX chip at the hardware level, which allowed a modest increase in productivity. The fact is that any chip (chipset, processor, video core) of any manufacturer has minor errors that the user never sees, thanks to the additional program code in the drivers. And, as a rule, these errors are eliminated in the next stepping chip, resulting in an additional code is not needed, and the system works a little faster. Therefore we can say that, despite the almost complete identity specifications “northern” bridges 790FX and 890FX, the last chip – better.

system diary technology news blog, computers internet blog, computer hardware reviews

The only significant difference between these “bridges” is a new version bridge compound A-Link Express 3 with a capacity of 4 GB / c. This is logical, since the “southbridge” SB850 adds support for interface SerialATA 6 Gbit / s, and the increased capacity of the disk subsystem must meet the bus bandwidth between the “south” and “north bridge”.

Purpose of chipset AMD 890FX completely changed compared to the 790FX. This chipset is still designed for high-end motherboards, which are three or four slots PCI Express x16. However, we note that in the version with four PEG-slots on each of them stands out for eight lines of tires, but thanks to the support of PCI Express v2.0 specification with double bandwidth (compared to v1.0), about any performance drop it no go.

Motherboard ASUS Crosshair IV Formula is based on chipset AMD 890FX, and, as you guessed, it is the top product in the range of AMD-cards from this manufacturer. Incidentally, the family of motherboards ASUS Crosshair Formula very rich past. In particular, the first generation of this board (more on the chipset NVIDIA) was considered the best of all AMD-products, and third-generation (already on chipset AMD 790FX) showed record results in the field of overclocking. We are therefore very interesting to see how the fourth generation motherboards ASUS Crosshair Formula will be consistent with such a high fence, given predecessors.

Motherboard Gigabyte X58A-UD9 on chipset Intel X58

July 3rd, 2010 admin Posted in Computer Hardware | No Comments »

Gigabyte company released a very interesting motherboard X58A-UD9 on chipset Intel X58, which immediately attracted the attention of the whole IT-industry. The reason is quite clear – on this board is installed, seven (!) Slots PCI Express x16, and board size exceeds the size of a standard form factor ATX.

system diary technology news blog, computers internet blog, computer hardware reviews

Of course, the market already present on board chipset Intel X58, which has four PEG slots, in particular – a model ASRock X58 SuperComputer, which is made in a standard form factor ATX. However, the fundamental difference between these boards are. The standard Intel X58 chipset provides for the needs of developers of 36 lines, bus PCI Express v2.0, that in the case with four PEG slots for maximum configuration of 4×8. At the same time, the motherboard Gigabyte X58A-UD9 for each of the four “core” PEG slots allocated to 16 lines of tires, that the amount required to 64 lines. Gigabyte engineers have additional lines PCI-E by installation fee of two chips NVIDIA NF200, in this case is a “core” PCI-Express slot with alternation, which allows you to install four video cards with dual slotted cooling system.

Between these slots are “additional” PEG slots, which are allocated to eight lines of bus PCI-E. Moreover, the data lines are collected “from the” core “slots, and the final distribution lines, PCI-Express bus is as follows – 8 8 8 8 8 8 16. It is clear that the installation of two additional chips NVIDIA NF200, as well as other essential elements, has led to the need to increase the size of payments to the form factor XL-ATX – 262 mm x 345 mm.

The motherboard X58A-UD9 is the flagship product line Gigabyte, so it is not surprising that the developers have set her a large number of additional controllers. The most powerfully realized disk subsystem, which includes 10 (!) Channels SerialATA 3 Gb / s and two channels SerialATA 6 Gb / s. In this case the engineers left the support of one channel ParallelATA, that allows you to connect to the board a total of up to 14 drives! Other possible extensions are also made at a high level, as a set of overclocking tools. Therefore, the reasons for the hype around the board Gigabyte X58A-UD9 become so understandable.
