David L. Farquhar on technology old and new, computer security, and more
Many years ago, I wrote something titled Memory Buying Secrets. That post is lost to history, thanks to migrations in this site’s early years, but there are a number of things you need to know when you’re buying memory that can save you money and frustration, so I figured I would revisit that topic today. Here are my tips for buying computer memory, based on decades of experience. Read more
Lionel used 15 different types of light bulbs in its O gauge electric trains in the postwar era, but in most cases–87% of catalog numbers, and a lot more than that in actual number of items produced–you can get by with two. Since knowing when can be difficult, here’s a Lionel train light bulb chart.
Lionel almost always specified 14 or 18 volts. Using an 18-volt bulb in place of a 14-volt original, or a 22-volt bulb in place of an 18-volt original results in longer service life. And there were two base types that Lionel used more than any other. Read more
One of my college buddies (Hi Christian!) shared my previous post on Facebook, pointing out that I’m a long-suffering Royals fan in Cardinals country, and adding that what I said was balanced and dispassionate.
I’m normally anything but dispassionate. But in this case, it’s not a baseball matter–it’s a business matter, and neither my employer nor any past employer is involved, so it’s easy to be detached and dispassionate. I guess you can say my take on hacking has changed. I was going to say “evolved,” but “changed” is more dispassionate.
The now-infamous breached Houston Astros database sounds like a classic case of what security professionals call Shadow IT: a project that the business needs, done without adequate involvement from security and, most likely, from the IT department as well.
These kinds of things happen a lot. A go-getter implements it, cutting through red tape to get a useful project done in record time, and it’s great until something goes wrong.
In this case, “wrong” meant a competitor got into the database and stole trade secrets.
So, about a year ago, the Houston Astros announced their internal player database had been breached. This week, more details emerged, pointing right at the St. Louis Cardinals.
It wasn’t a terribly sophisticated attack. You knew I’d write about this, but I’ll explore it from an IT security perspective more than from a baseball perspective.
Most of us have an old router like a Linksys WRT54G laying around, or if we don’t, it’s very easy to find one–the nearest garage sale or thrift store is a good bet–but sometimes all we need is a switch, to hook up a couple more computers or other devices to a wired connection. Using a router as a switch wastes some of its capabilities, but it’s easy to do. Here’s how to use a router as a switch.
Friday I saw a story from a financial publication suggesting that DDR3 DRAM prices will be increasing soon due to increasing demand for PCs, thanks to Windows 10’s release and the back-to-school season.
That got me thinking, and while memory prices aren’t at an all-time low right now, they are pretty cheap. A Crucial Ballistix Sport 16GB kit runs about $105 right now. About two years ago, I paid $99 for the same kit. According to the pricing history available to me, the cheapest it’s ever been was $70, and the highest it’s been is $160.
Years ago, I brought a Lionel 2026 locomotive in for repair that had belonged to my dad. It ran poorly, and either dad or his kid brother had taken it apart at some point and lost some of the parts, including the front truck.
And then, when I got the locomotive back and I put it on the track for a test run, it derailed constantly. The front truck just wouldn’t stay on the track, no matter what I did.
If you’re thinking about canceling your cable TV subscription to save money, you might be worried about buying an antenna, only to find your TV isn’t capable of receiving over-the-air broadcasts.
If you live near a major metro area though, you can test it with a one-cent paper clip.
I’ve read a few things here and there about Waze, a crowdsourced GPS that runs on smartphones, including those that run Android, Apple, and Windows. Its premise is simple: Based on how traffic is moving, it figures out the fastest way to get where you want to go. It adds intelligence to the GPS.
The trade-off, of course, is that it’s tracking you too. The data is anonymized, they promise, but it’s up to you to decide whether it’s a showstopper.
