When I was 19 or 20, I paid a visit to my old grade school to do some computer repair. My fifth-grade teacher dropped in, saw me cleaning up the contacts on a circuit board, and asked why I wasn’t using Everclear. Cleaning electrical contacts with Everclear is, at least, a practice people talk about a lot.
Well, I couldn’t legally buy Everclear yet, for one thing. But let’s talk about why Everclear is good for cleaning electrical contacts but there are other things that can be better.
I’ve been asked a few times now for my recommended DD-WRT settings, or at least my good-enough settings. I think that’s a great idea, so I’ll walk through how I configure a DD-WRT router. Follow these steps and I can almost guarantee you’ll have the most secure network on your block.
For the purposes of this tutorial, I am going to assume you are configuring DD-WRT as your primary router.
I was reading reviews of televisions and found several televisions had negative reviews because they only had a single HDMI port. The guy who bought it had wanted to connect two game systems to it. But you usually can connect more than one game system to a TV with one HDMI port.
I’m not sure who buys a television without first making sure it has all of the inputs you’ll need in order to connect stuff to it. But this problem has a solution other than buying a more expensive TV with two HDMI ports.
I went looking for a reliable, modern controller to use on my Retropie setup. I eventually settled on a Logitech F310, betting the Logitech F310 on Retropie would make a nice combination based on my experience with other Logitech peripherals in regards to their quality and value for the money.
The reviews I found suggested the F310 continued in this tradition, and I found enough people who said they got it working with Linux to feel confident I could get it working on the Raspberry Pi. And sure enough, I did.
I paid $18 for mine, and my first impressions of the quality were good. It’s precise, and button pushes register with a slight click. It’s no worse than a Sony, Microsoft or Nintendo controller, and if anything, I think I liked it a little better. A pair of Logitech F310s costs more than the Raspberry Pi board, but playing games is a lot more enjoyable when the controller does what you want it to do all the time, not just most of the time.
The F310 wasn’t a drop-in replacement for the controller I’d been using, though. I had to configure it for Retroarch, the software that provides most of Retropie’s console emulation.
Rubik’s Cube turned 40 this week. In a reflection of how much faster the world moves today than it used to, I remember Rubik’s Cube from the early 1980s, when it was a big, national craze. I had no idea at the time that it was invented in 1974 and took six years to reach the U.S. market. I asked for one for Christmas in 1981, and so did everyone else I knew. We all got one. And none of us could solve it. Granted, some of that may have been because we were in grade school, and the early years at that. My best friend’s older sister, who was in sixth grade or so, had a book, and she could solve it with the book’s help.
It was even the subject of a short-lived Saturday morning cartoon. I only watched it once or twice. It turns out it’s not easy to make engaging stories about a six-sided puzzle. There were tons of cheap knockoffs out there too, but unlike the knockoffs of today which are generally regarded as better, the 1980s knockoffs were generally worse. After a year or three, the craze died down. We moved in 1983, and I don’t remember anyone in our new town talking about Rubik’s Cube. Mine ended up in a drawer. I’ve looked for it a few times over the years, but never found it. Read more
I’m reading a book called Trade-Off, by former USA Today technology columnist Kevin Maney. It’s primarily a marketing book.
Maney argues that all products are a balance of fidelity and convenience, and highly favor one or the other. He additionally argues that failed products fail because they attempted to achieve both, or failed to focus on either one.
An example of a convenient product is an economy car. They’re inexpensive to buy and inexpensive to keep fueled up, but don’t have much glitz and you probably won’t fall in love with it. A high-end sports car or luxury car is a lot less practical, but you’re a lot more likely to fall in love with it, and gain prestige by driving around town in it. Read more
The smartest guy in the room cited the Commodore command LOAD “*”,8,1 as something he used for years but never understood why it worked except it was the command he used to load games on his Commodore 64.
So I explained it. Now I can explain it to you too. Read more
