Fixing the .NET Framework when it b0rks on you

The bane of my existence as a sysadmin was .NET. It would corrupt itself randomly, sometimes taking with it this awful CA product written in .NET that nobody else wanted anything to do with.

In my day I’d reinstall service packs and the latest patches and one of the six things we tried would fix it. I rarely knew which one. But that was five years ago. Today, as long as you’re running .NET 4.5.1 or earlier, Microsoft has an automated tool that repairs it. You can run it as a GUI app or from a command line or script. Curiously, it doesn’t support 4.5.2 yet–maybe that means 4.5.2 doesn’t break. We can dream, right?

Normally I’d say upgrade to 4.5.2 since its end of life is in 2023, as opposed to 2016, but until the fix gets revised to support 4.5.2, I won’t blame you for staying back on 4.5.1. Availability is 1/3 of security, after all.

Removing the Windows XP Repair scareware

Windows XP Repair is a fake system optimization and repair tool. It takes over the computer almost completely, and it’s a pain to remove. Worse yet, there’s at least one version floating around right now that standard no antivirus/antimalware tool I threw at it recognized.

Here’s how I removed it for someone.

Upgrade and repair diary: IBM Thinkpad T30

I picked up an IBM Thinkpad T30 this week. People ask me occasionally to keep an eye out for an inexpensive used laptop, and Thinkpads from 2005 or earlier are a good choice because they’re generally well built, easy to find, and most importantly, parts and information for them are plentiful if anything goes wrong.

In the case of this particular model, that’s a good thing.

Glue for plastic models and buildings

I saw a question for the millionth time on a forum about what glues to use on plastic models and buildings. So I’ll cover the topic here, where it won’t get purged after 8 months.

Ask the question at a hobby shop, and the answer comes down roughly 50/50 whether to use some type of super glue (cyanoacrylate, often abbreviated CyA or CA), or some type of MEK-based plastic weld, such as Tenax 7R. Every once in a while, someone pipes up about the tube cement I used as a kid. You don’t want to use that stuff. If you’ve ever tried, you know why–it’s messy, dries slowly, and the bond isn’t as strong as it could be. Read on and I’ll give you the advantages and disadvantages of both alternatives, plus some secrets.

Super glue tips and tricks

Super glue tips and tricks

If you want some secret super glue tips and tricks, I have you covered.

I just read a great tip about how to store Cyanoacrylate for long periods of time without it drying out on you. Cyanoacrylate (often abbreviated CA or CyA), sold under the Krazy Glue, Super Glue, Superglue, and a number of other brand names, is cured by the moisture in the air. Moisture in the air also causes a tube or bottle to dry out quickly after you open it.
