There are not many people who can seriously put into question the projected dominance of Google search technology in the future evolution of the Internet. Through his brilliantly engineered software architecture and conceptual maps of its' potential applications, supergenius Tim Berners-Lee, the acknowledged inventor of the World Wide Web, has for years been carrying his message of a "semantic web" that will make the current incarnation of the web seem look like your Dad's Rolodex by comparison.
In Berners-Lee vision, the next generation of web technology will be semantic, i.e. all data will be interconnected and capable of communicating with other "information" through a common language so speak. The following article discusses the development of the semantic web alongside the related, but not parallel development of Google’s search, mapping, and tracking applications. Berners-Lee is not anti-Google, but he is passionately against the centralization of web data and any form of proprietary control over Internet content.
I also encourage you to check out this very insightful video presentation in which Berners-Lee takes you on a virtual tour of the Web from its’ beginnings into tomorrow. This is fascinating stuff. Please share your thoughts with the Ashworth Blog community after brainstorming on your own.

Have you seen the recent commercials from Verizon Wireless touting their wireless service, contrasting their service with the seemingly restrictive confinement of WIFI. This is part of a battle for wireless dominance. WIFI is the current wireless standard leader. If you have a laptop, chances are you have some sort of WIFI router device in your home to provide WIFI access for it and other devices in your house such as the newest IPOD release. You have probably utilized the WIFI offerings of a local coffee shop or hotel (I couldn’t imagine staying in a hotel today that didn’t offer WIFI or at least Ethernet network access). If you download a free program called NetStumbler and install it on a computer that has a wireless card, you can discover wireless access points wherever you are. The program makes a sound every time a new WIFI point is discovered. Driving around with your laptop running NetStumbler can make your computer sound like a video game as it will sound off repeatedly like a machine gun as it find the plethora of WIFE points in the area.
The problem with WIFI is that it is spotty and not predictable. WIFI has a limited range and many WIFI hotspots are now guarded with security such as WPA, disallowing public access. This has created a demand for a more streamlined wireless standard that offers blanket coverage.
One option is the cell phone companies such as Verizon. These services can offer as much as much as 3.5 Gig of network throughput, putting WIFI to shame. WIMAX is another option in which metropolitan areas can offer blanket coverage throughout the area with speeds up to 4 Gig. Both of these offerings work on some sort of subscription plan which can cost as much as $60 a month. Unlike WIFI, each and every device must have a separate subscription, making these alternatives very expensive. Over a dozen metropolitan WIMAX projects have been dismantled over the past year due to higher than predicted costs and a shortage of willing subscribers. WIFI has also fired back with the new 802.11n WIFI standard this year which offers greater throughput and coverage than its WIFI predecessors. The battle has just begun for wireless dominance…
If you are purchasing a PC today over $700, chances are the specs include a dual core processor. Multi-core processors have been thetrend for several years. A dual core processor is a CPU with twoseparate cores on the same die, each with its own cache. It’s the equivalent of getting two microprocessors in one. A typical server today has at least two dual core processors. Quad cores are also very popular too. The organization that I work for typically uses dual quad core processors for any of the servers that will be carrying a processing load such as a database server, email server or a virtual host.
But as you can surmise, it’s not stopping at quad core. Intel will be releasing a six core processor later this year. AMD will be releasing theirs early next year. These will be strictly targeted at the server market since desktop software can barely fully utilize dual core processing. And if 6 isn’t enough, both companies plan on releasing a 12 core processor sometime in 2010.

There isn’t a profitable business segment today that isn’t competitive and that even includes the SPAMMING industry. Two of the biggest Spamming organizations, Nugache and Storm are currently going at each other head to head to dominate the SPAM/malware market. Yes, there is a market for SPAM and malware. Surprised? These organizations are not owned and operated by legitimate business people. No in is yet sure who is behind Storm but many IT security experts feel that Nugache is linked to the Russian Mob, aka the Russian Business Network.
Both of these organizations distribute SPAM through Zombie networks and both have been involved in highly criminal activities. Zombie networks are composed of PC’s across the globe, which have been compromised by some type of Trojan Horse which allows the Zombie controllers to then use them to send SPAM, conduct phishing attacks or other types of illegal activities. Each of these organizations control hundreds of thousands of computers. Take Storm for example. Some IT security experts have estimated that the Storm Zombie network, called the Storm Botnet, runs anywhere from one to fifty million computer systems. Even the most conservative estimates place the size somewhere around 150,000 to one million. The Storm Botnet in 2007 accounted for 8% of all malware on Microsoft Windows computers.
This year, Storm has an extremely viable competitor, Nugache. Although its zombie technology is not as sophisticated as Storm’s (for instance, Storm is somehow able to send SPAM in the native language of the receiver while Nugache cannot) Nugache has a big thing going for it right now, price. In an attempt to unseat Storm from its botnet dominance, Nugache has initiated a price war. Nugache will send one million emails for only $100. For $800 you can send 10 million emails.
It is because of the ridiculously meager amount of money that is required to SPAM a million people that SPAMMING is very profitable, even if the response rate to SPAM is only .01%. It is the sophistication of these controllable zombie networks that worry IT security professionals. Many fear that the current war for control of the malware market is only the beginning of this illegal destructive industry.
Johnny Lee is a brilliant technologist who’s become a YouTube star through his amazing demonstration of Wii remote hacks. After watching this video, you’ll never look at your Wii the same again. I love this video because Lee once again proves how integral human creativity and ingenuity are to the process of technological innovation. In this case, a relatively unknown guy like Lee on center stage at the famed TED conference, reinventing the very essence of what an already popular technology’s applications can ultimately be. These hacks are insane. Don’t miss this one…

Even in a poor economy, the IT job field remains hot. Despite the current economic woes, IT employment for the first quarter of 2008 shot up more than 12% compared with a year ago according to Information Week Magazine. The US added a total of 376,000 IT Jobs, making a total of 3.8 million people in the IT field.
This bodes well for future graduates of Ashworth University’s information technology programs because the biggest increase is in the computer support specialist field which grew by an astounding 41% in the past year, adding 127,000 jobs. Network and system administrator jobs grew by 31%, adding 51,000 jobs total. Despite the sustaining perception that the IT field has been weak ever since the IT bubble collapse and that all the jobs are going to India, the industry has added nearly 600,000 new jobs since its low point in 2002. In a digital and virtual world, the IT labor market is here to stay.
The 2008 Global Information Security Workforce Study was recently released. A total of 7,548 professionals in the field were surveyed. The complete study can be downloaded at https://www.isc2.org/cgi-bin/content.cgi?category=510
The most interesting headline from the study was the fact that 70 percent of all respondents reported that their own employees are the biggest threat to their organization’s security. This is contrary to the common belief that organizations must throw most of their resources at the outside perimeter of the organization’s network to prevent outsiders from accessing their network.
This premise is supported by a recent finding that email is now no longer the number one manner in which viruses access an organization’s network. With the ease at which employers now bring in thumb drives, personal laptops and PDA’s. Network security plans must focus on an umbrella approach that guards the entire network.

Back in 2000, we were constantly told that the world was running out of IP addresses. This was because IPV4, the IP standard we use for IP addresses only has so many mathematical combinations, thus there is a defined limit to the number of IP addresses that can be utilized. Due to the wide spread use of IP in the world, a usage rate far beyond what the creators of IP ever visualized; the IT world was stressing out as to how to address the problem. The solution was a new standard called IPV6 which introduced more bits into the addressing scheme. In turn, millions of additional mathematical combinations were created, resulting in an equal number of additional IP addresses.
Unfortunately, IPV6 is more complicated than its predecessor, requiring a degree of training for networking professionals. We were told back then that IPV6 would be implemented by the middle of the decade and alleviate the crisis.
Well guess what? It’s 2008 and the world hasn’t run out of IP addresses which is why IPV6 is barely used in the industry today. This is because of the wide popularity of NAT, Network Address Translation, which is used by most organizations that have a WAN presence.
For those unfamiliar with NAT, Network Address Translation allows a single device, such as a router to act as an agent between the Internet (or “public network”) and a local (or “private”) network. This means that only a single, unique IP address is required to represent an entire group of computers. This isn’t to say that IPV6 will wither on the vine. As of right now, government offices are required to transition to IPV6 within the next couple of years and other organizations are planning such an implementation in the future, but IPV4 is and will continue to be alive and well for some time to come.
One of the security weaknesses experienced with laptops and other portable computer devices for many years is the simplicity in which their drives could be compromised if the device is stolen. This was especially true before Windows XP and Windows 2000 when a thief could simply install a second operating system on the laptop, logon to the new operating system and gain admin rights to all the data on the drive.
Windows XP and Windows 2000 introduced EFS, Encryption File System, which allowed users to encrypt files of their choosing. Because the encryption was centered on an encryption key based upon the original operating system, an intruder couldn’t access that file simply by accessing it through another operating system. However, this required the user to individually encrypt every file or folder in order to protect all of their data. Needless to say, the majority of users failed to do this.
Microsoft has introduced a new technology called BitLocker with Windows2008 and premium flavors of Windows Vista. BitLocker encrypts the entire drive, including the Windows system files necessary for startup and logon, which could give an intruder the ability to discover passwords and logon information. What’s more, BitLocker utilizes a feature called Integrity checking which analyzes the early boot components and helps to ensure that data decryption is performed only if those components appear unmolested and that the encrypted drive is located in the original computer. This prevents thieves from stealing your hard drive and putting it into another computer to access the data.
It will also make it much easier for organizations to recycle old computers as they will not have to worry about erasing data on machines being decommissioned as the drives will be inaccessible. BitLocker is a great new addition to the Windows operating system and should be implemented by any organization or individual that works with sensitive data.
