Less Linux, more Windows
I’ve always been a pro-Linux type of guy. I started using Unix back in 1992 (SunOS) and then onto Slackware, Red Hat, Ubuntu. Linux offered so many more features, security, power to do anything and a reliability Windows couldn’t dream of at the time. Linux was a true multitasking OS, had a firewall, and all internet clients and servers one may want or need: pop3, smtp, http, ftp, ssh. All these were virtually impossible to do on MS-DOS or Windows, and I’m not even talking about the various crashes and ridiculous uptimes of the early Microsoft platforms. Since then, and up until a few months ago, it’s always been clear to me: reliability and security on Linux; office work, graphical user interface and leisure on Windows. (Feb 05, 2010)
How would you punish a spammer?
“Last time out I suggested sentencing spammers to some quality time in a maximum security cell with an ex-biker named "Tiny." But I think that's too good for these people. They should be strung up by their thumbs and forced to watch ShamWow infomercials and Rick Astley videos until their ears bleed.” Robert Cringely, InfoWorld 1 (Feb 03, 2010)
Incompetent email security spam filters cause historic business to change name
The Beaver is, at 90 years old, Canada’s second oldest magazine. Founded in 1920 and named after Canada’s symbol and fur-trading history, the Hudson's Bay Company publication is devoted to popularizing Canadian history, aiming to make Canadians more aware and appreciative of their heritage. Two weeks ago, the venerable magazine had to change its name to Canada’s History because its newsletter and emails were being trapped by spam filters around the world. (Jan 29, 2010)

We need spam to sell our anti-spam
The ISP market is a jungle: it’s every man for himself and leave the wounded behind. Some time ago, I subscribed to a big ISP (that shall remain nameless) that was leading the market. When I subscribed, I gave my chosen username for the email address – although it was included with the service I never used it (I didn’t even configure it). The username is a mix of things that make it unique and pretty much unreachable through dictionary attacks, something like 667gptfoo99x@. (Oct 26, 2009)
Drive by Downloads
This is a term I’m seeing more and more frequently in security-related web posts and, frankly, I thought it was fairly new. After doing some research, however, I found an article entitled, Anatomy of a “Drive-by-Download,” that was written in 2004 (!) by Eric L. Howes. Where have I been all this time? (Oct 21, 2009)

Hello my Friend… My name is Irina
Since “Russian wife” spam is on the rise, I’ll take this occasion to tell you a little story. An old colleague (let’s call him John) answered one of those messages about 2 or 3 years ago, just to see how things would go.
