Buying a new TV that won’t kill your electric bill

Last Updated on April 15, 2017 by Dave Farquhar

As television technology improves, they become more energy efficient. Generally speaking, at least. The CRT TV ranging in size from 26-32 inches that was common in living rooms for most of my lifetime used around 130 watts. But some of the monster TVs people are buying these days use more power than the fridge. Read more

I got a new side gig

I’ve been talking a lot with WhiteQueen at Rabbit-Hole lately, and learning a lot. It’s one thing to learn security from textbooks and learn enough to pass a test. It’s one thing to patch servers and make sure my servers pass annual security audits. It’s quite another thing to talk to someone who actively seeks out hackers to study their movements and try to keep them out. Or who stands up servers just to see how difficult it is to get in by force instead of through the logon prompt.

Both WhiteQueen and RedQueen have tons of ideas and tons of knowledge in their heads. But neither likes to write. After I banged out a 600-word article this week based on a five-minute conversation with him, WhiteQueen approached me with the idea of posting security-related articles on Rabbit-Hole. We think having quality, useful articles going up over there on a semi-regular basis will help them build a larger audience, and I’d never attract that audience working on my own. I’ll be learning as I go, and sharing what I learn in the process.

I’ll continue to write here about whatever it is I feel like writing about. I must have a half-dozen things not related to security that I’m working on right now anyway. When I post something over there, I’ll link to it from here to make it all easy to find.

Computer won’t boot? Check your USB ports

Last Updated on October 11, 2019 by Dave Farquhar

A friend called me in panic. A brand-new computer, freshly reinstalled with Windows 7, suddenly wouldn’t boot.

I couldn’t figure it out. I looked up the manufacturer’s 800 number and suggested she call. Sure, I could fix the problem eventually, but the manufacturer would know the quirks of the motherboard they used better than I would. I’ve given up on trying to give anything but the most basic, superficial support of anything I don’t own myself–especially when it’s not sitting in front of me.

He had her change the boot order. For some reason the system was trying to boot off its RAID array before the SSD. That explained why the system took a couple of minutes to get through POST, then spend a few seconds booting. But that didn’t fix the problem. Read more

Attack of the $99 Droid-Pads

A 7-inch, underpowered Android tablet that may or may not be available at your corner Walgreen Drug Store is made some big waves today.  It’s underpowered, but it’s supposedly on sale for 99 bucks. Regular retail price is $129.

Yes, for 99 bucks, it’s a toy. But it could be a fun toy. Read more

Why every sysadmin needs to know how to hack into Windows systems

Last Updated on January 23, 2022 by Dave Farquhar

Yesterday, Lifehacker posted an article called How to Break Into a Windows PC (And Prevent it from Happening to You). Some people weren’t happy that they posted a tutorial on how to hack into Windows systems.

Let me tell you why every sysadmin needs to know how to hack into Windows systems, given physical access. I can give you three scenarios that I’ve run into. Read more

A look back

I don’t remember the specific date anymore, but it was 11 years ago this month that I finished proofreading the galleys for what became my book. And I’ve had several people ask me recently–including my boss–why I haven’t written another one. Read more

Sorry about earlier

This site was down most of the day. The storms that hit the midwest today didn’t do a lot of damage in my neighborhood, but they did cause some power hiccups after I left for work, and my network didn’t completely recover on its own. I had to pick up the pieces when I got home for the day.

Such are the perils of running a site on a budget, at home.

My first Windows 7 build

Last Updated on April 17, 2017 by Dave Farquhar

I rebuilt a friend’s Windows 7 system this week.

The system includes a 30 GB SSD to boot from, and a RAID 1 mirror of 1 TB drives for storage. Aside from the two 1 TB drives, it’s basically a collection of $100 components. $100 Asus motherboard, $100 video card, $100 CPU. It seems like right now, no matter what individual system component you’re looking at, $100 buys you something really nice without going too far over the top. I’m sure certain aristocrats might disagree, but any reasonable person ought to really like using this system. Read more
