David L. Farquhar on technology old and new, computer security, and more
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?
The Digiland DL718M tablet is an inexpensive (sub-$40) tablet sold at consumer electronics stores like Best Buy. Make no mistake, a Digiland tablet is 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, or today’s equivalent, is one you can get today if you want.
Someone I know got a tech support scam popup that said their computer was being hacked. I said to bring the computer over. I wanted to see it.
I found the malicious site in the browser history–I’ll tell you how to do that after I finish my story–and pulled the page back up. The computer played an MP3 file with a scary-sounding message and urged me to call an 888 number. So I called. I got voicemail. I left a message.
A friend shared something about toxic blogs last week, which got me thinking to a change I made to how I find a writing topic last fall, when I set out to make my own blog less toxic.
When I write, I keep one question in mind: Is this going to help one person a week for the next several years, if not decades?
I had an interesting question come in the other day: What are the differences between Department 56 and Liberty Falls?
There are some significant differences between them but it turns out it’s entirely possible to use them together. Here’s how.
Most buying guides for monitors assume you’re buying a really expensive monitor for gaming. But there’s a lot more to look for than refresh rate and response time.
A good monitor can last 10 years and multiple computers, so it pays to make a good decision when buying one, even when you’re not spending $500. There can be a significant difference even between two $100 models, or between a $60 model and a $70 model, that will save you money in the long run.
If you’re fixing an old train or some other electrical device, some of the wires have crumbling insulation, and disassembly isn’t an option for whatever reason, then you can repair crumbling insulation with a $6 product called Plasti-Dip.
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.
New computer, old monitor: I see questions fairly frequently about using a new computer and older monitor together. More often than not, it’s possible to do, but you may need to know where to look for the cables and adapters you’ll need.
Here’s some help.
If you need to fix a chip, gouge or nick in an LCD display, you can do it with a dab of petroleum jelly and the edge of a credit card.
