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.

Tribute to the Asus SP97-V

Tribute to the Asus SP97-V

In need of an obsolete but reliable PC for a project, I searched a dark corner of my basement, a last stop for castoff PCs before being sent off for recycling. I found one. Predictably, it had an Asus motherboard in it. Specifically, it had an Asus SP97-V in it, a budget Socket 7 board from the late 1990s sporting a SiS chipset with integrated video that worked well with Cyrix and AMD CPUs.

A real world example of TEMPEST

In studying for my CISSP, the topic of TEMPEST came up. TEMPEST is, essentially, interpreting the electromagnetic waves given off by electrical devices to recover the data they contain. This can happen accidentally, or on purpose.

An accidental example of this happened to my neighbors in college.Darren lived directly below me. Scott lived across the hall. Darren had a cheap, no-name 486SX clone, and he lived on it. Problem was, it interfered with Scott’s TV.

One night, Scott got fed up with it and called Darren on the phone. "Get off your computer," he said.

"Can’t. I’m doing my homework."

"No you’re not, you’re playing Solitaire. Cut it out so I can watch TV."

Not only was Darren’s computer interfering with Scott’s TV, but Scott could see what Darren was doing. Not plain as day, but close enough.

The next semester, Darren traded his PC in for a slightly faster Dell, and Darren’s Dell got along just fine with Scott’s TV.

Extreme examples like this are rare, but possible. Even today.

How to buy a laser printer

I had to buy a laser printer in a hurry over the weekend. I bought a Samsung ML-2525, which I believe to be a reasonable choice, but not necessarily the best choice I could have made. It’s tiny, whisper quiet, and very fast, and it was on sale for 70 bucks, though sometimes you can get one for as little as $59. At that price, it’s hard for buying it to be a terrible decision.

Please note that this advice is for home and light small-business use. For business use, scroll to the end.

The joy of monitors

One of my monitors died this week. It doesn’t happen nearly as often as it used to, which is a good thing. Flat panel LCDs are more reliable than CRTs were. The dead monitor is an LCD, but it was a cheap and nasty Dell 15-inch made in 2001. I bought it used, and for much less than it was worth (even if it was made for the modern-day equivalent of Packard Bell), so I got my money’s worth out of it.

This weekend I went monitor shopping, with a budget of one hundred bucks.When buying new or semi-new, $100 is pretty much the lower limit. Nobody wants to sell a monitor for any less than that. Historically that’s usually been the case anyway. What’s amazing is what $100 will buy. 19 inches is pretty standard, although you’ll have to shop around a bit, and what you’ll buy will probably be a closeout.

Still, that’s remarkable. I remember paying more than $400 for a 19-inch CRT that dominated a desk. This would have been in 2001 or 2002.

And I remember talking with a champion Black Friday shopper several years ago bragging about how many LCDs he was able to scoop up for $200 apiece. These would have been 15-inch models, at best.

My timing turned out to be good though, as woot.com was selling a refurbished, debranded HP 20-inch LCD for $99 yesterday. I picked one up. I would have been satisfied with a 19-inch model, but the local stores had sold out of their 19-inch HP monitors. I’m not terribly picky about monitors, but I’ve really come to like the current generation of HP displays.

Will this monitor still work in 2017? I don’t know. But I have two other LCDs from 2001, both of which work fine. So it might.

Back in the CRT days, I wouldn’t buy anything but an NEC, because I’d never seen any other brand consistently last 8 years. It’s nice to be able to buy any old brand and expect that kind of lifespan today.

First impressions: HP Mini 110

I spent a few hours last night with an HP Mini 110 1012NR. It’s a model with a 16 GB solid state drive (no spinning mechanical hard drive) and Windows XP.

My biggest beef is the keyboard. It’s undersized, and I can’t touch type on it. Try it out before you buy one.

The rest of the system isn’t bad, but there are some things you’ll want to do with it.The system acted weird until I removed Norton Antivirus 2009. By weird, I’m talking not staying on the network, filesystem errors, chkdsk running on reboot, and enough other goofiness that I was ready to take the thing back as defective. The system stabilized as soon as I removed Norton Antivirus, and stayed stable after I installed ESET NOD32.

The system also ran a lot faster.

Don’t believe the hype about Norton Antivirus 2009. Use ESET NOD32. This is the second HP laptop in a month that’s given me Norton Antivirus-related problems.

McAfee is better, but only sufficiently better to use if your ISP is giving it to you for free. I still think NOD32 is worth the $40 it costs. The Atom CPU in the Mini 110 feels like a Pentium 4 with NOD32 installed. It feels like a Pentium II or 3 with something else installed.

The SSD isn’t a barn burner. I have OCZ Vertex drives in my other PCs, and this one doesn’t measure up the Vertex. Reads are pretty quick, but writes can be a bit slow. Windows boots in about 30 seconds. Firefox loads in about five. Word and Excel 2000 load in about a second.

So it’s not bad. But an OCZ Vertex would be a nice upgrade. Drop it in, use it for the OS and applications, and use the stock 16 GB drive for data.

A memory upgrade would also be worthwhile. With the stock 1 GB, it’s hitting the pagefile to the tune of 400 MB.

Unfortunately, to really make the computer sing, you’re looking at spending $200 in upgrades ($40 for NOD32, $40 for 2 GB of RAM, and $120 for an OCZ Vertex). Spread it out over the life of the machine and it wouldn’t be so bad though. And you’ll be paying $40 a year for antivirus no matter what you use.

The build quality is typical HP. I have lots of aged HP and Compaq equipment that’s still going strong. I don’t get rid of HP stuff because it breaks, I get rid of it because it’s so hopelessly obsolete as to be useless. I hesitate to buy from anyone else, except Asus. And Asus, of course, is HP’s main motherboard supplier.

If you can get used to the keyboard, I think the Mini 110 is a good machine. It weighs 2 pounds and is scarcely larger than a standard hardcover book, so it fits almost anywhere. And having an SSD, there isn’t much that can fail. The battery will eventually fail, and probably the AC adapter will too, but I think other than that, one of these computers could last 20 years, assuming it would still be useful for anything then.

Saying goodbye to my Lexmark 4039

Today we hauled my trusty Lexmark 4039 off to recycling. Unfortunately its paper handling was shot, and parts and documentation for that model are nearly impossible to find. I found the alleged service manual, but couldn’t make sense enough of the documentation to fix it.
