Via ZDNet Asia:
Traditional phone operators will be forced to change their approach as wireless VoIP technology surges over the next few years, say analysts.
Sales for wireless VoIP tech for both dual and single mode devices are forecast to generate global revenues of US$82 billion by 2012, according to a report by Juniper Research.
Basharat Hamid Ashai, author of the report, told silicon.com: "VoIP is dramatically changing the service provider market. With the advent of VoIP over Wi-Fi, it will cause providers to rethink how they retain customers."
Ashai added wireless VoIP will reduce demand for landlines, leaving the door open for non-traditional carriers, such as internet or DSL providers, to sell voice services.
He said: "The marriage of VoIP and wireless technology has gained a lot of attention in the last couple of years, with many industry experts believing it to be the next killer application to revolutionize the telecoms space."
Windows Vista is one of the most ambitious software projects that have ever been undertaken by Microsoft. It is more revolutionary than evolutionary, though, in the sense that it is still backwards compatible with most of the previous programs in XP.
This creates a problem for Microsoft as it makes XP the largest competitor of Vista as most users opt to stick with XP or wait a few more months before upgrading to Vista to give Microsoft more time to work out the bugs. Nevertheless, Windows Vista is packed with a lot of new features and upgrades that makes it the definite next-generation OS for computers.
Determining Compatibility and Upgradeability of the Old PC
XP users can check how upgradeable their systems are to Vista by connecting to Microsoft’s online Vista upgrade advisor. Here you can check if your computer has the right hardware (RAM, speed, disk space, etc) to handle at least the Vista Home Basic Edition. Vista Home Premium Edition, Ultimate Edition and Business Edition require a lot more hardware power. Windows XP users can also check out some of the new features or applications of Vista using their current OS by downloading the new Windows Media Player, Internet Explorer 7 and desktop search utility.
Determining Compatibility of Software and Hardware
Some hardware, especially the older models, may fail to work with Windows Vista. To avoid this, make sure that the hardware you install in your computer has a logo or certification from Microsoft that either says “Certified for Windows Vista” or “Works with Windows Vista”.
Hardware that is “Certified for Windows Vista” means that it is optimized to take advantage of the new applications or upgrades of the new OS. The list of hardware, drivers and software supported by Vista is still a bit short at this time but it will definitely get longer as Microsoft works out the kinks in the system and hardware vendors start adapting their drivers to the new OS.
Windows Vista Installation
After making sure that the computer is Vista Upgradeable, Windows Vista may be installed either by clean install which basically wipes out the old OS or by simple upgrade which installs the new OS on top of the older one.
A clean install means that the user will have to back up his files, applications and settings before deleting the old OS. The Easy Transfer tool that comes with Vista, however, enables the user to do this fairly easily.
A dual boot system could be a great way of assessing the new Vista’s features and functionalities while retaining the reliability and familiarity of the old OS. To successfully create a dual boot system, one has to install Windows Vista by booting the computer using the installation disk of Windows Vista as opposed to directly installing it from within windows XP. When Vista is installed from within XP, Vista is assigned to a different drive or partition and this creates confusion for the applications and programs running on the system.
DRM or digital rights management are restrictions on copying, duplicating and sharing of downloaded content such as software, utilities, movies and digital music. DRM enforces the copyrights of companies by forbidding end users to load a software application on more than one computer, sharing digital and protected content through the internet or burning disks containing copyright-protected media.
Companies with DRM or copyright protection systems use the argument that these are to make sure that intellectual property will be protected and quality is maintained. There are cases however when DRM applications may endanger the security of your system or may perform unwanted actions in your computer.
An example of this undesirable DRM result is when installed software takes priority over other programs in order to perform efficiently. Another case may be when end-user license agreements contain clauses that give companies the right to change agreements whenever the need arises. This happened when Apple Computer changed the allowable times a user can burn a song to a CD from ten to seven without the users knowing it.
Security Risks from DRM Applications
Sometimes DRM can also lead the user’s personal information to be sent to the manufacturer or the company where the DRM came from. This may cause security issues in a user’s system. An example of this was when Microsoft released its Windows Genuine Advantage Antipiracy program as an update to Windows Editions. Installation of this program then led to the system’s security features being compromised.
Sony BMG also created software that is designed to protect their newest release of digital music. This led to end-user systems’ reduced efficiency in preventing Trojans from being installed. After several class action suits, Sony withdrew the DRM software from succeeding batches, promised to get an independent assessment of DRM software that will be released with its products in the future and offered free music downloads to all the consumers that were affected by the program.
Laws on DRM and Copyright Protection
The law itself does not help much to protect the end users from these kinds of DRM applications. This is evinced by the large number of cases the Recording Association of America has filed against people who have shared music files over the internet. The law also makes it hard for people and companies to asses the security risks of these DRM applications as the Digital Millennium Copyright Act forbids reverse engineering of these DRM programs.
Avoiding DRM-Related Risks
To avoid the possible security issues a DRM application may cause, users can opt to download or buy CDs that have unprotected MP3 format music instead. Users are also encouraged to carefully read the end-user license agreements before installing software to give them an idea about what the software will do when installed and what the companies can do in the future. A backup library system or backing the files on CD audio format will also be a good investment to make sure that files are insured against any unforeseen actions of DRM applications.
Operating System Upgrades
Perhaps the most glaring change users will notice in the new Windows Vista is the increased security on all levels of the OS especially the OS kernel. The new Windows Vista comes with its own Windows Defender and Firewall to secure a computer from hackers, viruses and spywares through limiting access to the critical parts of the OS to windows programs. Vista has also increased capabilities in hardware and drive management as well as application programming interfaces.
Enhanced I/O scheduling, multi-processor sync and memory management through OS kernel changes are also available with the new Vista. Other low-level function upgrades also improve some basic tasks or functions such as task switching, security, performance and reliability of the system. Vista’s SideShow makes it possible for devices with auxiliary screens to display pertinent information without the need for the system to be powered on
Networking Upgrades
The new Windows Vista will also have an upgraded networking capability with its auto-tuning means through TCP window scaling and IPv6 native support in the new TCP/IP stack.
Performance Enhancers
Performance enhancers are also a part of the new Vista package. SuperFetch monitors frequently used programs and preloads them for faster user access. ReadyBoost permits faster flash memory data transfer through high-speed USB drives; this makes it a very effective supplementary swap file. ReadyDrive allows faster data transfer for hybrid hard drives as it has built-in flash memory caches and low priority I/O mechanisms that enable maintenance and security checks without excessive operations disruption. This means that you can run the anti virus or defrag applications in the background without noticing any degradation in the system’s performance.
NET 3.0 Framework Incorporation
The new Vista also incorporates the NET 3.0 framework. This extends the capabilities of Windows API such as Windows CardSpace known formerly as InfoCard, Windows Communication Framework known formerly as Indigo and Windows Presentation Foundation or Avalon. Central RSS store and native RSS support allows the users to detect RSS feeds through an RSS reader sidebar in the new Internet Explorer 7.
Hardware Support and Capabilities
The new Windows Vista is compatible with the new computer devices coming out of the market today. Furthermore, more realistic simulations and games are possible with graphics hardware virtualization, graphics memory paging, supporting geometry shaders, DirectX10 and a lot of other features integrated in the OS. This upgrade in graphics capability is also readily evident through the live previews of windows and documents, scalable icons, animations, flip 3D view in switching windows and glass-window frames that Vista users will see on their desktops.
Vista is also capable of supporting newly released computer technologies and peripherals like Blu-ray and HD DVD devices, HDTV cards, etc. Architecture of drivers for the printer and Audio were also upgraded along with the integration of Media Center in the Vista Edition (for tablet PC and laptop users) for stability and enhanced performance. Further upgrades to Tablet PC and laptop users includes personalized handwriting recognition, improved pen navigation and touch screen support.
I just installed a replacement keyboard in my Dell Latitude D800.
I called up Dell yesterday and told them that I had lost a keycap. The replacement keyboard arrived this morning.
The replacement was amazingly easy. It required removing only two screws, and Dell even sent me the screwdriver.
My Latitude gets a lot of abuse and the old keyboard was filthy. I’m glad I don’t have to clean it now.
Dell Customer Service is top notch!

I recently purchased a Buffalo Terastation HS.
I bought the 1GB model, which contains four 250MB ATA drives. I configured them as a RAID 5 array, which gave me a total of 750MB of disk space.
I’ve downloaded replacement firmware for the device from the dedicated fans at Terastation.org. This firmware adds the ability to telnet to the device. Once you do that, you can access the embedded Linux upon which the device operates.
Theoretically, I could replace the 4 250GB disks with larger drives, but 750GB fits my storage needs — today.
The real downside to the device is performance. The unit is CPU bound and that limits the speed at which you can copy data to and from the device.
Performance of a NAS device will never quite equal performance of DASD. I chose to go with a NAS solution because I wanted RAID 5 and I wanted a central storage device which would not be reliant on any of our computers.
The best feature of this NAS solution is the price. This is an awesome price for a home of SMB NAS solution.
If you don’t need high-performance file copies, this device is highly recommended.
Product Features
- Four operational modes: Standard, Spanning, Mirroring and RAID 5
- Removable hard drive rack allows quick swapping of hard drives should a drive fail
- 10/100/1000 Gigabit Ethernet port and Jumbo Frame capability for higher transfer speeds
- Four USB 2.0 ports, allowing 4 simultaneous USB connections
- Built-in print server for sharing and managing a USB printer on the network.

The CEO of T-Mobile says that VoIP service will be far less disruptive on mobile devices than it has been on fixed line telephony:
VoIP (voice over Internet Protocol) services provided over mobile phone networks will have “far less impact” than those offered over fixed-line networks, Akhavan said Tuesday on the sidelines of a news conference at the 3GSM conference in Barcelona.
“There are all sorts of technical issues that make mobile VOIP services difficult to implement,” he said. Technical issues related to how networks pass on IP addresses of mobile users have not been completely resolved, he noted. “Take reachability, for example: How can the call come to me?”
Akhavan also said emergency phone service and “always on” connectivity are also big issues, since staying online takes up bandwidth on pricey mobile networks.
And then there’s price: “When people talk about VOIP, they think free,” Akhavan said. “With any mobile service provided over the Internet, you’re going to need to buy a data package.”
Mobile VoIP “will take a small share” of revenue generated by mobile voice services, he said.
