What is a Botnet anyway?

Sometimes, those of us in the computer biz get so wrapped up in the techie details that we forget that many people don’t know what we think are the basics. For example, a really smart, computer-savvy friend of mine recently asked me, “What is a botnet anyway?” Whoops! Clearly, it’s time for me to do some explaining.

So, to start with his question, Botnets are networks of Windows PC, which have been taken over by malware programs. While it’s theoretically possible that a Mac or a Linux desktop PC could get a botnet malware bug, in practice, their better security makes them harder targets for botnet creators so they avoid them.

Your computer typically gets infected by botnet malware by a virus or worm. You get these by opening up an infected attachment or by visiting an infected Web site. Most modern anti-viral programs like AVG, Norton Anti-Virus, or Kaspersky Anti-Virus, will keep your machine safe from these attackers. If, that is, you keep your security programs up-to-date. Stale anti-viral software is worst than useless.

Steven’s handy desktop Linux guide

With so many desktop Linux distributions, unless you’re an expert it’s hard to know what’s what. Since I’ve been using desktop Linux almost since day one, and I’ve used every major distribution out there and many of the minor ones. I think I qualify as a desktop Linux expert, so here’s my quick and dirty guide on picking out the right desktop Linux.

You’re sick of Windows, but you don’t want to spend a lot of time learning Linux. If that’s you, get a pre-installed Ubuntu Linux PC. Ubuntu is easy to use, and you can get ready-to-go laptops from Dell and System 76 among other companies.

You no longer want Windows, or you’re not interested in ‘upgrading’ to Windows 7, on your business PCs, but your office is using a Windows-based server infrastructure. If that’s you, you’re in luck. While some people really dislike Novell for partnering with Microsoft, if you want a Linux desktop that will work hand-in-glove with Microsoft servers and AD (Active Directory), Novell’s SLED (SUSE Linux Enterprise Desktop) 11, is for you.

Seven reasons to skip upgrading to Windows 7

My colleague Preston Gralla came up with seven reasons to move to Windows 7. And, they are pretty good, but good enough to switch away from XP, or to skip Mac OS X Snow Leopard or desktop Linux? I don’t think so.

Let me open up by saying though that if you’re using Vista-you poor, poor person-yes, you should migrate to Windows 7. After all, Windows 7 is really just Vista without the warts. Otherwise, no, I don’t see any compelling reason to switch.

I say this as someone who’s also been running Windows 7 since the late betas and I’m currently running the RTM (release to manufacturing) version. I like Windows 7, but if you were to ask me what the big feature, the ‘wow’ that would make you want to go to the trouble of moving to Windows 7, I’d be left without anything to say. Heck, look at Gralla list, number one on the list is the new taskbar. Microsoft wants me to spend big bucks for a new taskbar!?

OK, on with the list.

Security is a process

I often point out that Windows is insecure. It’s so insecure, in fact, that I, in all seriousness, propose that ISPs (Internet Service Providers) should start forcing users to secure Windows-since neither users or Microsoft will do the job, Windows PCs should be banned from the Internet. That said, nothing, and I mean nothing is really secure.

People keep having this delusion that security is a product. That, if you just buy some magic box, you’ll have a program or an operating system that’s as secure as Fort Knox. Or, if they just use a Linux desktop or a Mac, they’ll be safe. I wish!

It doesn’t work that way. Security is a process, it’s not a product. Some systems are more secure than others. Linux, as anyone who pays any attention to security news knows, is a lot more secure than Windows. If we were talking cars, Linux would be an Audi A4, the Mac, BMW 330 and Windows would be a mid-70s Ford “Hit here to blow up” Pinto.

Microsoft banned from selling Word

It sounds like a joke. But, it’s real and it’s anything but a joke for Microsoft. Judge Leonard Davis, of the U.S. District Court for the Eastern District of Texas, has issued an injunction (PDF Link) that "prohibits Microsoft from selling or importing to the United States any Microsoft Word products that have the capability of opening .XML, .DOCX or DOCM files (XML files) containing custom XML."

Microsoft had been sued by i4i, a collaborative content solution and technology company. Its founder, Michel Vulpe, owned a patent covering a way of reading XML (Extended Markup Language) documents. XML is the basis of Microsoft’s controversial Open XML document formats. The U.S. District Court for the Eastern District of Texas is infamous for supporting patent lawsuits and fast-tracking them. In intellectual property law circles, this Court has become known as "A Haven for Patent Pirates."

In this case, though, i4i isn’t a patent troll. It’s a real company that uses its patented technology in real products. It also believes that Microsoft has used its patent in Word. And, what’s to the point, they convinced Judge Davis of this.

On May 20th 2009, Judge Davis and his court’s jury ruled that Microsoft owed i4i a $200 million patent infringement verdict for having infringed on i4i’s "A system and method for the separate manipulation of the architecture and content of a document, particularly for data representation and transformations," patent # 5787449.

Microsoft didn’t settle. Boy, was that a mistake.

As lawyers who have dealt with Judge Davis before know he doesn’t suffer fools lightly. So on August 11, he signed the order that blocks Microsoft from selling Word. According to the document, "This injunction becomes effective 60 days from the date of this order." So, on or about October 12th, Word, and Microsoft Office since all versions contain it, will go off store shelves.

Some people, like Michael Cherry, an analyst with Directions on Microsoft, don’t think that Microsoft will have to stop Word sales. Sorry. Microsoft may very well have to stop sales or disable Open XML, Word’s new standard document format. This injunction will not be easy to dodge.

Nick Eaton at SeattlePI reported that, Microsoft wants to fight this out. Eaton wrote that Microsoft spokesman Kevin Kutz said, "We are disappointed by the court’s ruling. We believe the evidence clearly demonstrated that we do not infringe and that the i4i patent is invalid. We will appeal the verdict."

Good luck with that Microsoft. No, I’m not being sarcastic.

Now, I am not a lawyer, but I know something about IP law and a fair amount about markup languages since I’ve been covering them since SGML (Standard Generalized Markup Language), showed up in the late 1980s and before anyone had dreamed up the Web’s HTML (Hypertext Markup Language) or XML. To me, the i4i patent reads like a classic, over-reaching patent that covers prior art, which should have prevented it from ever becoming a patent. It’s these kinds of patents, and courts like the Eastern District of Texas, which approve these IP patent lawsuits almost as a reflex, which harms everyone in the technology business.

As anyone who reads my stuff knows, I’m no fan of Microsoft. I also think Open XML is a junk standard. But, that said, while Microsoft’s legal team certainly mishandled this case so far, Microsoft doesn’t deserve this kind of punishment for this particular misdeed.

This time it’s Microsoft’s turn to be bashed, but next time it may be an open-source company, or your company. Many big technology companies pay up to patent pirates,

Obama, open source & healthcare

Linux-based and open-source healthcare software has been around for years. Unless you were in health IT, however, chances are you never even heard of it. It’s time to pay attention, because it may soon be tracking your medical records.

With the passage of ARRA (American Recovery and Reinvestment Act of 2009), $19-billion dollars has been ear-marked for Medicare and Medicaid technology incentives over the next five years. Collectively, this program is known as HITECH. If open-source, medical software advocates have their way, some, if not most, of that money will be going to free software and open standard based EHR (electronic health records).

The most important of the open-source EHR systems are the ones built on VistA (Veterans Health Information Systems and Technology Architecture), the US Veterans Administration’s public domain EHR. Don’t let the name fool you. VistA has nothing to do with Microsoft Vista. The core, open-source VistA code is called WorldVista.

Like Linux with Canonical and Novell, WorldVista has been commercialized by ISVs (independent software vendors). The best known of these suites is Medsphere’s OpenVista.
