Is it safe to use drain cleaner in garbage disposals? Generally, the answer is no. Unfortunately I speak from experience.

There have been three major types of Lionel knuckle couplers produced since resuming train production in 1946. Lionel knew it would have to make a splash when it brought its trains back after the end of the War, and the knuckle coupler was one of the keys.
Two of these coupler types are compatible with one another, but one has a gotcha.

I was trying to install some software last week and I got an NSIS error like the one to the right. The message certainly suggests corrupt downloads, but corrupt downloads are relatively rare, and when they happen, redownloading it ought to clear that up. Getting two of these failures in a row with different programs is really a freak occurrence, so I started looking for another problem.

I went to install Linux (Debian) on an old Asus socket 775 motherboard (a P5LD2) and had a litany of problems getting my installation media to boot. Here’s how I finally got it installed.

Last Tuesday night my oldest son came into the room and told me he thought one of our computers was being hacked. So I kicked into incident response mode and walked into the other room to be greeted with a computer loudly telling me that Microsoft Security Essentials was unable to clean a virus and to immediately call Microsoft.
Instead I immediately shut down the computer. Here’s why.

I did not invent this technique. Last week Al Osterud, a veteran Marx collector of many decades, shared a technique for removing and installing Marx coupler springs without the skills and steady hand of a microsurgeon.
All you need is a piece of 1/8-inch K&S square tube, which resembles the tool Marx used to install them at the factory, and a toothpick or a straightened paper clip. Marx wouldn’t make anything that wasn’t easy to put together, which made its couplers so maddening to work on. Why was it easy in the factory and nearly impossible at home? With the right tools, it is indeed easy.

In the past, I’ve recommended Secunia PSI as a way to keep your systems up to date. I know from my own experience that it helps, but I also know it doesn’t work 100 percent of the time.
When it comes to security, nothing is more critical than making sure your updates are applying correctly. That’s where my employer comes in, with Qualys Browser Check.

If your router has a USB port and is running DD-WRT, you can turn it into a DD-WRT USB print server. It can still do wireless duty while it allows your computers to print to your wired USB printer over your wired or wireless network. It’s not very intuitive or user friendly, but it works. Here’s how to set it up with Windows 7. Other Windows versions will be about the same.

I met with a client earlier this week who asked me to go over their vulnerability scans for a bit of a sanity check. He asked some important questions, but one in particular seems worth sharing. What can we do with Java? Can we solve the Java problem?
