The 15-second rule and other (non) myths

The 15-second rule and other (non) myths

Cnet investigated some computer wise tales, myths, conventional wisdom, or whatever else you want to call it. The one I take the most issue with is the 15-second rule. They asked Geek Squad, and, as a long, long-ago Best Buy employee, the answer they gave to the 15-second rule is, well, what I would expect. Read more

How to connect Commodore disk drives

How to connect Commodore disk drives

Connecting a single drive to a Commodore C-64, 128, or VIC-20 is pretty easy: Plug a 6-pin serial cable from the port on the back of the computer to one of the two ports on the back of the drive. It doesn’t matter which port you use. The second port is for “daisy chaining” additional peripherals, such as a printer, or multiple drives. And even though a fast load cartridge speeds up the drive, it plugs into the computer.

Older drives like the 1540, 1541, and 1571 are self-contained. Plug a power cable (which, conveniently, is no different from the power cable used on a most desktop PCs) into the back and power it on. Later 1541-IIs and 1581s use an external power brick. The two drives’ power bricks are interchangeable; however, they do differ from the power brick used by the computer itself. Fortunately, the original power bricks are labeled with the compatible devices, either on a silver sticker on top or molded into the underside.

It’s multiple-drive setups that get trickier. Read more

How to connect a Commodore 64 or 128 to a modem

I guess it’s not exactly obvious, to someone looking at a Commodore 64 or 128, how a modem plugs in. Commodore modems plugged into the port on the far right hand side, looking from the back. If the port is labeled at all, it will be labeled “User port.” Although it had other uses, that port was used for modems far more than for any other purpose.

They used the modems to call a BBS, and what they did on the BBS wasn’t always legal. But that’s another story.

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

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

Of politeness and consideration in the connected age

I’ve quit several online forums in recent months, and lately I’ve been noticing a lot of Facebook wars–discussions that just got out of hand too fast. All of this makes me extremely nostalgic for the days of Commodore 64s and 128s, dialup modems, and hobbyist-run BBSs. It was hopelessly primitive compared to what we have today, but for the most part it was polite, and it certainly felt more like community.

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.

Dinosaur hunting

Today I slipped over to Laclede Computer Trading Company for the first time in many years. I was in search of an ISA parallel card. They’re not easy to find these days, mostly because they aren’t particularly useful to most people these days, but I figured if anyone would have one, it would be them.

No dice. But man, what memories.

The rise and fall of Shack, and how to fix it

Wired has a nostalgic piece on the not-quite-late, not-quite-great Radio Shack. I think it’s a good article, but it glosses over part of the reason for the store’s decline.

It blames computers.But blaming computers ignores Tandy’s long and successful run in that industry. Most Apple fanatics and other revisionist historians conveniently overlook this, but when Apple launched the Apple II in 1977, Tandy and Commodore were right there with competing offerings. I don’t know about Apple, but Tandy and Commodore were selling their machines faster than they could make them.

Why don’t wins count anymore?

In Kansas City, baseball fans are celebrating. In St. Louis, they’re fuming.

It’s usually the other way around. Right now, Royals fans are celebrating Zack Greinke’s highly deserved Cy Young Award. In St. Louis, fans are complaining that Chris Carpenter and Adam Wainwright, expected to finish 1-2 in the voting, got "snubbed" and lost to San Francisco’s Tim Lincecum, who won a total of 15 games.

Greinke, for what it’s worth, won 16.The Cy Young Award usually is "the pitcher with the most wins" award. And that makes a little sense–Cy Young won 511 games in his career, the most all-time. And that itself shows the problem with wins.

Cy Young is the winningest pitcher of all time, but he’s not the best. Walter Johnson won 417 games pitching mostly for last-place Washington Senators teams. Put him on the teams Young pitched for, and he would have won more than 511 games. Win 110 games over the course of your career and you’re considered a pretty good pitcher. Johnson pitched 110 shutouts.

I learned playing Micro League Baseball in the mid 1980s that wins are an overrated statistic. Cy Young was an outstanding pitcher, but Walter Johnson and Lefty Grove could beat him most of the time. Advanced baseball statistics barely existed in the mid 1980s and my Commodore 64 sure didn’t know anything about them, but I quickly started paying attention to WHIP–walks plus hits per innings pitched.

In their best seasons, Johnson and Grove permitted fewer than one baserunner per inning. And they permitted fewer baserunners than Young. Fewer baserunners means fewer chances to score, which means a better chance of winning.

Greinke and Lince*censored*won on the strength of their advanced statistics. Carpenter and Wainwright were very good this year. But they gave up more baserunners per inning than Greinke and Lince*censored*did, and other advanced statistics also indicated that Greinke and Lince*censored*were the better pitchers last year.

In the case of Greinke, the Royals lost six games in which he gave up one run or fewer. Yes, you read that right. Six times, Greinke took the ball, pitched seven or eight innings and gave up one run, or zero runs, and the Royals still lost.

So it’s easy to imagine a scenario where Greinke would have won many more games. Had Greinke pitched on a team that could consistently score more than two runs, had the Royals had more than one reliable relief pitcher to back him up, and had he had more than one above-average fielder playing the field behind him, for example.

Greinke realized he only had one guy behind him who knew how to catch the ball, so he would intentionally pitch in such a way as to make them more likely to hit a fly ball to wherever David DeJesus was playing, usually left field.

Lince*censored*suffered from less bad luck than Greinke did, but still won his 15 games while pitching for a weaker team than the Cardinals.

According to Baseball-Reference.com, pitching for a team with average offense, Lince*censored*and Greinke each would have won 18 games. Under the same normalized conditions, Carpenter would have won 15, and Wainwright would have won 17.

Both pitchers had good years, and admittedly they played for a team that had problems. But Tim Lince*censored*pitched for a team with even bigger problems.

I see the words "which pitcher gave their team the best chance to win every fifth day" thrown around by St. Louis fans a lot. The answer, when you normalize the statistics, is Lincecum.

Or, to look at it another way: Carpenter’s and Wainwright’s win totals showcase just how good Albert Pujols is.

The case for Tim Lince*censored*was less clear than the case for Greinke, and that was why the vote ended up being so close.

But it’s obvious to me that the voters got it right in both cases. And that’s good.

Twenty five years ago, it wasn’t as easy to go much deeper than conventional statistics like wins, losses, and ERA. Today it’s simple, so there’s minimal excuse to pay attention to them.
