Attack of the $99 Droid-Pads

A 7-inch, underpowered Android tablet that may or may not be available at your corner Walgreen Drug Store is made some big waves today.  It’s underpowered, but it’s supposedly on sale for 99 bucks. Regular retail price is $129.

Yes, for 99 bucks, it’s a toy. But it could be a fun toy. Read more

My first Windows 7 build

I rebuilt a friend’s Windows 7 system this week.

The system includes a 30 GB SSD to boot from, and a RAID 1 mirror of 1 TB drives for storage. Aside from the two 1 TB drives, it’s basically a collection of $100 components. $100 Asus motherboard, $100 video card, $100 CPU. It seems like right now, no matter what individual system component you’re looking at, $100 buys you something really nice without going too far over the top. I’m sure certain aristocrats might disagree, but any reasonable person ought to really like using this system. Read more

Upgrade and repair options: HP Pavillion Slimline s7220n

I picked up an HP s7220n dirt cheap, then I found out why. It powers on just fine, boots, runs for a few minutes, then powers itself off. At that point, the power supply is hot enough that you don’t want to touch it. Effectively, it’s a Useless Machine with an Intel CPU and Windows XP. Read more

What burn-in is and why you should do it

A friend bought a new computer this month. It arrived sooner than expected, and she called to ask what she should do. I said, among other things, to set it up and leave it powered on continuously for at least 24 hours.

A coworker who had never heard that advice asked why.

Save money on cables by not buying at retail

Save money on cables by not buying at retail

I’m ashamed to say I own one Monster cable. Hopefully if I tell you I bought it at a garage sale for $2, I’ll regain your respect. But there’s an easier way to save money on cables than buying at garage sales.

Unless you need it immediately, there’s no reason whatsoever to buy Monster and other overpriced cables at big-box consumer electronics stores. Profit margins are really thin on most electronics, even the big-ticket items, and they use the cables to make up for that. That’s the reason nobody includes cables in the box.

SSD myths

SSD myths

SSDs, like most disruptive technologies, face some questions and resistance. People will grasp at any straw to avoid adopting them. Thanks to this resistance, a number of SSD myths arose. Here are the myths I see repeated over and over again, and the truth, based on my experience actually using the things.

Note: I originally wrote this way back in 2010. The drive technologies I speak of as state of the art are rather aged now. But the principles still hold today, and will continue to do so. Hard drives have gotten better, but SSD have gotten better at a more rapid pace.

What to look for in a router

I revisit the topic of what to look for in a router every six or seven years. As important as it always was, I think it’s even more important today, as there are a number of underpowered routers on the market and it’s best to avoid them.

This post originated in 2010. I revised it for 2017 needs, and by the time I was done, I’m not sure much of my 2010 text was left. But that’s OK.

Buy a used business printer and save a bundle

Buy a used business printer and save a bundle

I’m through with cheap consumer printers.

Due to the nature of my wife’s work, we print a lot by home standards. We buy paper by the case, not the ream, and a case of paper probably lasts us a little more than six months.

Our workload just isn’t practical for the kind of printers you find next to the telephones at consumer electronics stores. So I bought an HP Laserjet 4100. And even if a case of paper lasts you a couple of years, you might want to buy an office-grade printer too.

The Revolution of 1985

Twenty five years ago yesterday, a revolution happened. Nobody really noticed, and nobody thinks about it today, but the effects are still here. That we take these things for granted today shows just how wide-reaching the revolution was.

It took the form of a computer with a 32-bit Motorola CPU, full stereo sound, a display capable of 4,096 colors, and a fully pre-emptive multitasking operating system. At a starting price of $1,295, though it rose to closer to $2,000 by the time you added a second drive and a monitor.

The specs on that machine don’t sound all that impressive today, but keep in mind what else was available in 1985. The state of the art from IBM was the 16-bit IBM PC/AT with very limited sound capability, color as an expensive option, and DOS 2.1. Windows at the time was little more than a glorified DOS shell. Apple had its Macintosh, but it cost twice as much as an Amiga, had only slightly better sound than that IBM, and just a tiny black and white display.

Over the course of the next nine years, Commodore sold 3 million Amigas. Along the way, they worked out the early glitches in the machine, and upgraded the capabilities, though not always as quickly as the competition. But the machine aged remarkably well. And ultimately it did for television production what the Macintosh did for publishing, replacing hundreds of thousands of dollars’ worth of specialized equipment with equipment that merely cost thousands, and fit comfortably on a large desk.

The big problem was that Commodore sold those three million machines to one million people, and never really knew what to do with it. It should have been a great business computer. It was the ultimate home computer. It could have been the ultimate education computer. And it was the ultimate video editing computer. But Commodore never marketed it effectively as any of those.

Mostly the company went through the motions while financier Irving Gould lined his pockets with whatever money was left after Commodore got done paying the bills each quarter. Some years, Commodore spent more money on Gould’s and his yes-man company president’s salaries than they spent on Amiga development.

So, slowly but surely, the competition caught up. VGA was better in some regards than the Amiga graphics and worse in others, but over time, the combination of VGA and fast 386 and 486 CPUs became enough to keep pace. Macintosh graphics followed a similar curve. Affordable sound cards for PCs started appearing in the late 1980s and were commonplace by 1992 or 93. It was a lot harder to get it all working on a PC, but when it worked, it worked pretty well. But making DOS boot disks to get it all working was a black art, an art I remember practicing at least until 1998.

It was in the early 1990s that PCs and Macs got multitasking. First it was horrible cooperative multitasking, followed later by pre-emptive multitasking like the Amiga had. Eventually they even added memory protection, something Amiga didn’t have (when it was initially designed with an 8 MHz CPU and 256K of RAM, that was the one thing they had to leave out).

The money ran out in 1994, and the rights to the architecture changed hands more times than most people can count. The Amiga’s days as a mainstream computer–if it ever could claim to be one–ended then.

The rest of the world spent the 1990s catching up. When Windows 95 came out with its promise of Plug and Play, improved multimedia, and pre-emptive multitasking, it was all old news to Amigans. Amigas had been doing all that for 10 years already.

For a long time after 1994, I was bitter. I’m less so now that the rest of the world has caught up. But I still wonder sometimes what might have been, if the industry had spent the 15 years between 1985 and 2000 innovating, rather than just catching up.

How to revive an old PC

Somewhere, stashed in a corner of the basement or a closet, pretty much anyone who works on computers or even has just owned computers for a long time has a stash of obsolete hardware, stashed for a just-in-case moment.
