More Home Depot details emerge

Late last week, Home Depot finally released a statement about its data breach. At least they had the decency to call the attack “custom” and not spin it as “advanced” or “sophisticated.” Even “custom” is really a euphemism, as the attack wasn’t all that different from what other retailers experienced earlier in the year. It may have been as simple as recompressing the BlackPOS malware using a different compression algorithm or compression ratio to evade antivirus.

The breach involves about 56 million cards, making it a bigger breach than Target.  Read more

Happy late birthday, OS/2

Twenty-five years ago this month, on April 2, IBM announced its new PS/2 computers and a new multitasking operating system to run on (most of) them–OS/2. They even lured a bunch of the actors from M*A*S*H to do an ad campaign for them.

It didn’t seem like it at the time, but that was the beginning of the end of IBM’s PC business.

Happy Patch Tuesday, September 2011

Microsoft has five updates and Adobe has two for us on this fine Patch Tuesday, in addition to a patch Mozilla pushed out for Firefox last week.

Don’t get too complacent if you run something other than Windows. If you run Microsoft Office on a Mac, or Adobe Reader or Acrobat on a Mac, or Adobe Reader on Unix or Linux, you’re vulnerable. The vulnerabilities in those affected products are more serious than the vulnerabilities for Windows. So keep that in mind. Don’t be smug about security. It’ll bite you.

So there is a benefit to running Windows Server 2003 and XP

One of the reasons Windows Server 2003 and XP haven’t caught on in corporate network environments is that Microsoft has yet to demonstrate any real benefit to either one of them over Windows 2000.

Believe it or not, there actually is one benefit. It may or may not be worth the cost of upgrading, but if you’re buying licenses now and installing 2000, this information might convince you it’s worth it to install the current versions instead.The benefit: NTFS compression.

Hang on there Dave, I hear you saying. NTFS compression has been around since 1994, and hard drives are bigger and cheaper now than ever before. So why do I want to mess around with risky data compression?

Well, data compression isn’t fundamentally risky–this site uses data compression, and I’ve got the server logs that prove it works just fine–it just got a bad rap in the early 90s when Microsoft released the disastrous Doublespace with DOS 6.0. And when your I/O bus is slow and your CPU is really fast, data compression actually speeds things up, as people who installed DR DOS on their 386DX-40s with a pokey 8 MHz ISA bus found out in 1991.

So, here’s the rub with NTFS compression when it’s used on Windows Server 2003 with XP clients: the data is transferred from the server to the clients in compressed form.

If budget cuts still have you saddled with a 100 Mb or, worse yet, a 10 Mb network, that data compression will speed things up mightily. It won’t help you move jpegs around your network any faster, but Word and Excel documents sure will zoom around a lot quicker, because those types of documents pack down mightily.

The faster the computers are on both ends, the better this works. But if the server has one or more multi-GHz CPUs, you won’t slow down disk writes a lot. And you can use this strategically. Don’t compress the shares belonging to your graphic artists and web developers, for instance. Their stuff tends not to compress, and if any of them are using Macintoshes, the server will have to decompress it to send it to the Macs anyway.

But for shares that are primarily made up of files created by MS Office, compress away and enjoy your newfound network speed.

VMWare is in Microsoft\’s sights

Microsoft has released its Virtual Server product, aimed at VMWare. Price is an aggressive $499.

I have mixed feelings about it.VMWare is expensive, with a list price of about 8 times as much. But I’m still not terribly impressed.

For one, with VMWware ESX Server, you get everything you need, including a host OS. With Microsoft Virtual Server, you have to provide Windows Server 2003. By the time you do that, Virtual Server is about half the price of VMWare.

I think you can make up the rest of that difference very quickly on TCO. VMWare’s professional server products run on a Linux base that requires about 256 MB of overhead. Ever seen Windows Server 2003 on 256 megs of RAM? The CPU overhead of the VMWare host is also very low. When you size a VMWare server, you can pretty much go on a 1:1 basis. Add up the CPU speed and memory of the servers you’re consolidating, buy a server that size, put VMWare on it, and then move your servers to it. They’ll perform as well, if not a little bit better since at peak times they can steal some resources from an idle server.

Knowing Microsoft, I’d want to give myself at least half gig of RAM and at least half a gigahertz of CPU time for system overhead, minimum. Twice that is probably more realistic.

Like it or not, Linux is a reality these days. Linux is an outstanding choice for a lot of infrastructure-type servers like DHCP, DNS, Web services, mail services, spam filtering, and others, even if you want to maintain a mixed Linux/Windows environment. While Linux will run on MS Virtual Server’s virtual hardware and it’s only a matter of time before adjustments are made to Linux to make it run even better, there’s no official support for it. So PHBs will be more comfortable running their Linux-based VMs under VMWare than under Virtual Server 2003. (There’s always User-Mode Linux for Linux virtual hosts, but that will certainly be an under-the-radar installation in a lot of shops.)

While there have been a number of vulnerabilities in VMWare’s Linux host this year, the number is still lower than Windows 2003. I’d rather take my virtual host server down once a quarter for patching than once a month.

I wouldn’t put either host OS on a public Internet address though. Either one needs to be protected behind a firewall, with its host IP address on a private network, to protect the host as much as possible. Remember, if the host is compromised, you stand to lose all of the servers on it.

The biggest place where Microsoft gives a price advantage is on the migration of existing servers. Microsoft’s migration tool is still in beta, but it’s free–at least for now. VMWare’s P2V Assistant costs a fortune. I was quoted $2,000 for the software and $8,000 for mandatory training, and that was to migrate 25 servers.

If your goal is to get those NT4 servers whose hardware is rapidly approaching the teenage years onto newer hardware with minimal disruption–every organization has those–then Virtual Server is a no-brainer. Buy a copy of Virtual Server and new, reliable server hardware, migrate those aging machines, and save a fortune on your maintenance contract.

I’m glad to see VMWare get some competition. I’ve found it to be a stable product once it’s set up, but the user interface leaves something to be desired. When I build or change a new virtual server, I find myself scratching my head whether certain options are under “Hardware” or under “Memory and Processors”. So it probably takes me twice as long to set up a virtual server as it ought to, but that’s still less time than it takes to spec and order a server, or, for that matter, to unbox a new physical server when it arrives.

On the other hand, I’ve seen what happens to Microsoft products once they feel like they have no real competition. Notice how quickly new, improved versions of Internet Explorer come out? And while Windows XP mostly works, when it fails, it usually fails spectacularly. And don’t even get me started on Office.

The pricing won’t stay the same either. While the price of hardware has come down, the price of Microsoft software hasn’t come down nearly as quickly, and in some cases has increased. That’s not because Microsoft is inherently ruthless or even evil (that’s another discussion), it’s because that’s what monopolies have to do to keep earnings at the level necessary to keep stockholders and the SEC happy. When you can’t grow your revenues by increasing your market share, you have to grow your revenues by raising prices. Watch Wal-Mart. Their behavior over the next couple of decades will closely monitor Microsoft’s. Since they have a bigger industry, they move more slowly. But that’s another discussion too.

The industry can’t afford to hand Microsoft another monopoly.

Some people will buy this product just because it’s from Microsoft. Others will buy it just because it’s cheaper. Since VMWare’s been around a good long while and is mature and stable and established as an industry standard, I hope that means it’ll stick around a while too, and come down in price.

But if you had told me 10 years ago that Novell Netware would have single-digit marketshare now, I wouldn’t have believed you. Then again, the market’s different in 2004 than it was in 1994.

I hope it’s different enough.
