Solve the NSIS error

nsis_errorI 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.

Origin of CP/M’s PIP command

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?

Digiland DL718M tablet: a review

The Digiland DL718M tablet is an inexpensive (sub-$40) tablet sold at consumer electronics stores like Best Buy. Make no mistake, it’s a basic tablet for basic needs. But given reasonable expectations you can buy one of these and be happy with it.

This isn’t a new market by any stretch. But it seems like tablets in this price range are usually Black Friday specials, or only available on online marketplaces far abroad. The Digiland DL718M is one you can get today if you want.

Commodore 64 vs 64c

The Commodore 64 went through a number of revisions throughout its long life. The most outwardly visible of those revisions was the transition from the tan, boxy C-64 to the thinner, lighter-colored 64c. If you’e wondering about the Commodore 64 vs 64c, here’s what you need to know.

C64 vs. Apple II

The C64 vs. Apple II was perhaps the most epic battle of the 8-bit era. Both companies sold millions of machines, yet both nearly went out of business in the process.

Comparing the two machines with the largest software libraries of the 8-bit era is a bit difficult, but that’s what makes it fun. The two machines are similar enough that some people ask if the Commodore 64 was an Apple product. The answer is no.

As a weird aside, it was possible, with a Mimic Systems Spartan, to turn a C-64 into an Apple II. Not many did, but the reason why is another story.

Linksys EA6200 DD-WRT installation

I picked up a couple of refurbished Linksys EA6200 routers this past weekend. For whatever reason, DD-WRT isn’t officially supported on them, though it does seem to be a popular DD-WRT router. A lot of people make the upgrade far more difficult than they need to. With some simple hacks, Linksys EA6200 DD-WRT installation is pretty straightforward.

I came up with an 18-step process that I simplified just as much as I could. Unlike some methods I’ve seen, I don’t have you editing any binary files or creating custom startup scripts.

Download more RAM — Safe? Scam? Joke?

A software developer asked me today about a website called Download More RAM. I don’t think he heard my other coworkers snicker. He asked if it’s possible to download RAM, then asked if it was a security issue. I said it’s best not to visit it, and spared him the history lesson.

Yes, there’s some history to it.

Commodore 64 vs VIC-20

How do you compare the Commodore 64 vs VIC-20?

The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer.

But even though the two machines are closely related, there are significant differences between them. It’s important to remember that in the 1980s, two years was a comparatively long time because the market was moving so fast. Plus, the VIC-20 was always supposed to be an entry-level machine. In 1982, the 64 was supposed to be fairly high-end. Let’s compare and contrast the two venerable machines.

When will SSDs be cheaper than hard drives?

When will SSDs be cheaper than hard drives? Based on history, it’s possible to make an educated guess, and I’m going to do it.

Back in 2011, I noticed that historical hard drive pricing fell in line pretty nicely with Moore’s Law, and predicted that SSDs would do the same. I predicted that SSDs would reach 25 cents per gigabyte sometime in 2016, and was wrong. They hit that price in 2015. So I was late by a few months.

But I’m still willing to try to predict when SSDs will cost less than hard drives. I’ll predict when they’ll hit parity too.

Here’s a better laptop than the typical Black Friday specials

If you want a better laptop than the typical Black Friday special, I found just the thing: this Dell Latitude E6420 laptop from Newegg, for $225 (the price is good through Sunday, Nov. 22). It has several things going for it: it comes with Windows 7 Professional, so you can upgrade to Windows 10 when you want and you’ll get the better, more-feature-filled, easier-to-secure Professional version; you can upgrade the memory to 8 GB of RAM, and it comes with a 128GB SATA SSD, so you can drop in a bigger, faster SSD at a later date.

Note: When Newegg sells out of these, which happens occasionally, they’re fairly easy to find on Ebay, though some come with conventional hard drives rather than SSDs.
