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.
CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example. Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?
Someone asked me recently for a cost comparison of MTH Realtrax vs. Lionel Fastrack. Both are similar O gauge track systems with plastic roadbed. MTH’s system has been on the market a few years longer, but Lionel’s is more popular, in spite of being more expensive.
Let’s figure out just how much more expensive it is.
A week or two ago, a stranger approached me with some advice about securing routers: move SSH off port 22.
Since arguing with strangers is what the Internet was apparently invented for, I’ll argue against the benefits of moving SSH off port 22.
Windows 10 uses homegroups, but if you have systems that don’t understand homegroups and want to share a Windows 10 printer by UNC (the old school way to share a network printer), it’s not obvious how to go about doing it.
I couldn’t find a way from the GUI, but it’s still possible to share the printer from a command line.
One of the new features of Windows 10 is better file compression, which was intended to help Windows fit better in low-resource devices like tablets. But it’s helpful on computers with SSDs too. But for whatever reason that option doesn’t show up on mine.
But you can still compress your system files even if the Disk Cleanup utility (which you can also launch from the Free up disk space by deleting unnecessary files control panel) doesn’t show the Compress system files option.
Train transformer starting voltage is a harder question than it necessarily needs to be–because it’s varied over the years. Part of that is because intent has changed over the years.
Someone asked me recently about the Lionel CW-80 and how it compares vs older transformers. That’s a fair question, and one that tends to stir up a lot of emotions on train forums. So I’ll try to present the pros and cons in a fair manner.
Train transformers have one pair of screws for each output, which is generally enough for a simple layout, but once you have more than one accessory or building with lights in it, you’ll find it’s difficult to attach all of the wires to the transformer posts.
