Security+ test taking tips

One of my coworkers is being required to get a Security+ certification, and asked me for advice. She’s gone to class, read some books, and she’s going to another class on TCP/IP, but she’s just not comfortable yet. I gave her some Security+ test taking tips.

Since other people might be in her situation, I figure it’s worth writing about. Read more

Is TRIM better than Native Command Queuing?

Another question from the big bag ‘o search queries: When you’re shopping for an SSD, is TRIM better than Native Command Queuing?

It’s an interesting question, and my first inclination is to say no, because TRIM and NCQ solve two similar but distinctly different problems. But the more I think about it, the more I understand why it’s possible to confuse the two.

Living with a past-its-prime computer

I’m playing catch-up a bit. This weekend, Lifehacker ran a guide about living with a computer that’s past its prime.

I’ve made a career of that. One of my desktop PCs at work (arguably the more important one) is old enough that I ought to be preparing to send it off to second grade. And for a few years I administered a server farm that was in a similar state. They finally started upgrading the hardware as I was walking out the door. (I might have stayed longer if they’d done that sooner.) And at home, I ran with out-of-date computer equipment for about a decade, just this summer buying something current. Buying something current is very nice, but not always practical.

So of course I’ll comment on a few of Lifehacker’s points.

Microsoft’s leaked roadmap

Microsoft is getting aggressive with Windows release dates, and I can’t help but wonder if it’s going to put a damper on future sales.

Windows 8 is coming out in August, which was a poorly kept secret anyway. That can’t be helping Windows 7 sales, but at this point I think Microsoft is mostly concerned about new computer sales and corporate sales. What’s more concerning to me–initially–is the revelation that Windows 9 will be out in November 2014.

Pipe output to the clipboard in Windows

Besides all the changes to the GUI that happened post-Windows XP, they also made one useful change to the command prompt. When you run a command, it’s now possible to pipe output to the clipboard.

If you’re like me and write a lot of documentation, or you just take a lot of notes while doing computer maintenance, it’s a big boon.

Don’t use software firewalls: Good advice or bad?

A common piece of good-meaning advice you’ll hear is that you should never use software firewalls. But is that good advice, or bad?

On the surface, it’s good advice. It’s much better to use the firewall built into a cable/DSL router. But the software firewall built into Windows XP, Vista, 7, and (presumably) 8 makes for a good second line of defense, so I don’t recommend disabling it.

I’ll explain further.

Windows shutdown command

Windows shutdown command

Let’s say you need to shut down or reboot your computer from a command line, a batch file, or a desktop shortcut. Maybe you want to shut it down right now, or in an hour. You can do all of that and more with the Windows shutdown command, shutdown.exe.

Toggle between two hosts files with a simple script

A longtime reader wrote in asking if it was possible to easily toggle between two hosts files. There are several possible uses for this. When I’m at home, I need to address my web site by its internal, private IP address. On the road, that private address obviously doesn’t work. He wants something like this for other reasons; I believe he’s blocking ad servers with his hosts file and needs to unblock one or more servers temporarily for select sites to work properly.

This solution would make my Computer Science 203 professor rescind the B I received in his class if he saw it, but it works, and I don’t think he reads this blog anyway.

Windows 8 on a VM

If you’re looking to play around with the Windows 8 developer build that Microsoft pushed out this week, be aware that it won’t run on VMware player or any version of VMware Workstation prior to version 8.

It does, however, reportedly work on Virtualbox if you use the Windows XP compatibility settings. Read more

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.
