David L. Farquhar on technology old and new, computer security, and more
The bane of my existence as a sysadmin was .NET. It would corrupt itself randomly, sometimes taking with it this awful now-defunct product written in .NET that nobody else wanted anything to do with. Those were the bad old days. These days, there’s a better way to go about fixing the .NET Framework when it goes bad.
I’ve written about Truecrypt before. If you need cross-platform full-disk crypto, here’s an alternative I found recently. Veracrypt is based on Truecrypt, but since you can’t fork it without a name change, it has a different name.
I haven’t messed with it yet myself–yet–but if you need this, you probably already know it. And, for the record, I don’t believe there was any conspiracy against Truecrypt.
Apparently, 86% of WordPress blogs haven’t been upgraded yet to version 4.0 or 4.01, because they are vulnerable to a terrible cross-site scripting vulnerability.
If you’re reading this, and you have a WordPress blog, go update it. This post will still be here when you’re done. Read more
Mozilla, Akamai, Cisco, the EFF, and Identrust are teaming up for Let’s Encrypt, an effort to make SSL encryption free and easy.
This is important, because it means mundane stuff will get encrypted. When SSL/TLS traffic are no longer flagged as special, security will increase. Read more
So the sales fliers for the 2014 Christmas shopping season are out, and I’m seeing tons of cheap laptops. If you only have $200 to spend, they have something for you.
Some of them look like they’re even worth having. Yes, I’m shocked too. Here’s how to figure out which ones are worth taking home, and which ones are best left for some other sucker. Whether you’re shopping for yourself or someone else, you’ll probably want to keep the following in mind.
Many resources for up and coming go-getter managers tell managers to subvert or go around processes in order to get things done.
Let me tell you a story about that strategy backfiring.

My garage door wouldn’t go down. You know the drill–you push the button, the door goes down for a few seconds, then reverses course, and maybe your opener blinks at you a few times. Not all garage door openers do the blinky thing though.
The reason is simple. The safety sensors couldn’t see each other, so they assumed something, or worse yet, someone, was in the way, in danger of being hit by the door, and made the opener reverse course. As annoying as a door is that won’t close, a door that mashes stuff is a lot worse.
My sensors couldn’t see each other because we’d moved some stuff around and, I guess we bumped one of them. Read more
The Enerlites Top Greener HOSS is an occupancy sensor switch without ground wire requirements, and it’s pretty cheap too, at $12. A Lutron switch costs almost twice as much.
But the HOSS does come with some compromises. The HOSS does require a neutral (white) wire. But most switch boxes will have the whites in there and accessible, so that’s not a big deal. It’s also a bit trickier to wire than a Lutron, and it doesn’t look as nice.
That said, it’s nice to have an option for older houses that may not have a ground connection available. People in older houses need energy savings too. Read more
This past weekend was the annual Scouting for Food drive. My oldest son participated, and I was proud of him because he complained a lot less than the older kids.
In fact, he was perfectly happy running up and down people’s driveways, picking up bags, and putting them in the trunk of our car as I drove 3 miles per hour with the hazard lights on.
But somewhere along the way, something started to smell funny. Read more
If you’re in the market for some new PC gear, it helps to measure reliability and quality of hardware. How do you measure that? How about buying the one that induces the least buyer’s remorse? That’s an approach you can take with the data from Hardware.fr. It’s in French, but Google Translate works.
This doesn’t measure long-term reliability–only DOA rate and short-term reliability–but it’s data I haven’t seen before, so I think it’s a welcome resource.
