Going Places Senselessly

I am a driver who is perpetually lost.  I get lost going places I've been to dozens of times; to wit:  last month I got lost en route to my university, from which I drove home on the weekends for four years.

People say, "You know how to get here, right?"

Sheepish silence.

"Well, you've been here, right?"

More sheepish silence.

"Shoedame, you were just here last weekend!"  And they throw up their hands and start talking about landmarks.  Well, do you know where the 50-foot grain silo is?  With the robin's-egg-blue top?  Teenagers spray-painted profane graffiti on it in bright red paint."

No response.

In my defense, if their vehicles were full of my children they wouldn't notice landmarks either.  The Statue of Liberty could be relocated to their neighborhood and they would drive right by without noticing it.  The atmosphere in my minivan is. . .is. . .well, it's like this.  Interruptions are bracketed:

"MOM!  She has my hairbrush in her "[bag MOM!]" will you make them shut "[up I]" don't want to go to the pool, it's "[boring SHE]" still has my hairbrush, make her give it to "[me GET]" your thumb out of your mouth you stupid "[baby YELLOW]" punch buggy no punch "[back! OW!]" MOM! he hit "[me YOU]" said my boyfriend could come over can he come over "[tonight, SHE]" always has people over and I never have anybody over, I've been asking to have Kaitlyn over for a "[month WHY]" do we have to have all these dumb girls over, I want to have boys "[over I'M]" starving can we stop for soda?  Ice cream? "[Chips? I]" wanna make love in this club, in this club, in this clu. . .<click> MOM! why did you turn off the radio?"

Combine this level of distraction with my natural (nonexistent) sense of direction, and you have a family that is rarely where, or when, we are supposed to be.  We've gotten lost in every city, town, and outpost within 200 miles.  For years, I have been allowing an extra 45 minutes to get pretty much anywhere.  I consider this the minimum "getting lost time".  If Columbus had sailed the ocean blue with these five kids he'd have ended up in the Arctic circle.  We'd all be eating whale blubber right now.

So naturally, I've envied people with a GPS device to help them drive where they're supposed to be going.

That is, I envied them until I borrowed these devices and tried to use them.  You might think that with the noise level in my minivan, I wouldn't even be able to hear a GPS, but I actually can.  I can hold a GPS in my lap and turn it up to so many decibels that the polite, firm, schoolteacherish voice is louder than five kids and the radio.  So that's not a difficulty.  However, any GPS is a) hell bent on killing us all or b) gets us even more lost, if possible, than my sorry sense of direction.

I've concluded that the difference between having a GPS and not having one is that you get lost strangling a computer, or get lost not strangling a computer.

My mother's GPS directs me to turn into brick walls, cow pastures, and creeks with amazing accuracy.  It also proclaims that "you are now arriving at your destination" when nowhere within ten miles of the place.  "Turn left," it says.  "You are now arriving at your destination."  You look to the left at a ten-foot pile of mulch and ungraciously lose your temper.  Her GPS takes you to the correct street in a city and then demurs at directing you to the actual street number, which might be 25 blocks away.  Maybe Mom's GPS thinks that would be cheating; making it a little too easy for me.  Famously, Mom's GPS once announced that I had arrived to pick my son up from a college class at the Zippy Clean Car Wash. 

My boyfriend's GPS sounds like Mary Tyler Moore on crystal meth and is also possessed by the devil, or at least one of hell's lower-ranking imps.  It exclaims, in the middle of four-lane highways without so much as a shoulder, "turn right, then turn left.  Recalculating." He calls his GPS by a name I can't repeat and says, "You'd better recalculate, because I can't turn right or left."  His GPS is also confounded by exit and entrance ramps.  Get on a ramp and it freaks completely and the whole system resets.  These are ramps that the GPS actually picks out and directs him onto, and then thinks better of it.

My uncle Bob tells a story of being sent up a mountain road by his homicidal GPS which, due to a rock slide, had only one lane.  He was nearly run off the mountainside by a school bus and sought refuge in a ditch.  When he arrived, traumatized, at his destination, the townspeople asked, "you took the mountain road, didn't you?"  They could tell by looking at him.  "Don't ever," the locals intoned, with wagging heads, "take that road."

Computers, even satellite-directed ones, think drivers should take horrible, even potentially deadly, routes.  We poor human suckers are so used to believing whatever computers say that we might abandon paved roads for dirt roads, or cow paths through the woods, if computerized voices told us to.  Uncle Bob's harrowing journey reminds me of people who show up here on the front porch of the Shoe all sweaty and bedraggled and a lovely shade of "MapQuest Green"—their computers directed them to get here from the south by going over Mount Rogers—Virginia's highest elevation, 5,729 feet. This route shaves 20 miles off their journey and adds an hour and a half, the poor things.  In addition to the folly of Mapquest and Yahoo! Maps, our visitors' brand new, very expensive GPS systems often have no sense of road quality versus mileage, and bring them crawling at 20 mph over fifteen miles of unrelenting hairpin curves. Some turkey hunters arrived here by this method and were too exhausted to aim at turkey one; they pleaded to be directed to the nearest hotel and looked relieved when I pointed in the opposite direction of Mt. Rogers.

I'm not saying I've never gotten anywhere using a GPS.  Once, Mom's GPS directed me without a single mishap to the nearest Golden Corral—where I could have an excellent salad and a sliver of steak and admire the 400-lb diners for a mere $15, counting tax and tip, and do the cha-cha in the double-wide bathroom stall.  However, my bad experiences driving with a GPS far outnumber the good.  I have elected not to ask for a GPS for Christmas.  By gum, á la Frank Sinatra, I'll be lost, but much more than this, I'll be lost my way.
 

Royaltek GPS Mouse RGM-3600

Royaltek GPS Mouse RGM-3600

I have and use a Garmin Nuvi 350 for car navigation. It's a wonderful tool. Garmin is not a wonderful company to deal with.

I spent a day and a half trying to use the Nuvi with Kismet - a Linux war driving application. I finally managed to stream data from the Nuvi to my PC but I never managed to get it working with the application itself.

Sanity returned and I ordered this device off the 'net and it showed up in my mail box three days later. Plugged it in my laptop and the device ttyUSB0 showed up.

One line change to the configuration of GPSD - a program which makes may GPS devices look the same to other programs - and I could talk to and receive data from the GPS Mouse.

A one line change to the configuration of Kismet - a Linux war driving application - and I was logging latitude, altitude, elevation, time and mac address of every access point I drove by.

TP-LINK TL-WN422G Wireless USB Adapter

Plugged this device in my workstation, clicked the network manager application, selected my AP and it connected instantly on Ubuntu. Windows may harder but this looks like an easy alternative to running wires around the house.

You can pull the cap off the top and connect with the USB extension cable supplied.  A small strip of double sided tape would enable mounting to a wall or window for better connections.

The 4dbi antenna is removable and can be replaced with a 10dbi panel with an RPSMA connector.

TL-WA501G 54Mbps Wireless Access Point

If you are looking to add or expand wireless to your network, this is the device.

  1. Remember this is an Access Point not a router. You plug this device into your network, not plug your network into this device.
  2. It wirelessly connects everything to anything. It's an access point, client, repeater, bridge.
  3. Zero configuration as an access point. Plug it in, fire up your laptop and connect to the strongest signal you see. That will be this device. It outperforms routers costing triple the price.
  4. Learn how to configure the device using the simulator. Choose security from sharing to paranoid.
  5. Learn wireless networking essentials at the best FAQ in the business.
  6. Forget about DD-WRT and OpenWRT. This device has all the functionality you need (except maybe VLAN).

TP-Link is the largest manufacturer of SOHO (small office home office) in China and is rapidly expanding into International markets. After sampling a few of their products, the reason is clear - superb hardware at rock bottom prices.

Lazarus - Come Out

It stinketh. Entombed for over four days with no sign of life there was little hope.

The drive was recognized by the host machine but the data partition showed no sign of life.

Try #1. Boot the machine with UBCD4WIN (Bart'sPE). The data partition was viewable but files kept disappearing before my eyes. Within minutes, the partition disappeared like a ghost.

Try #2. Using a USB to ATA adapter plugged into a normally forgiving Ubuntu machine. It said the file system (partition) was corrupt.

Try #3. Booting Knoppix on the machine with USB to ATA adapter, the data partition reappeared but had no data.

Try #4. Put the drive in the "fridge" and went to bed. In the morning, both data and recovery partitions had vanished. After several minutes of power applied to the drive, both partitions returned and the data was successfully copied to another USB hard drive. Split the archives in two and burned to DVD.

We need another host computer and disk drive for the data, the original body is hazardous waste, but this data will live on.

Building a high-performance inexpensive PC

A few times each year, Woody, Jeff and I are called upon to come up a cost-effective upgrade or "new" PC. Not nearly often enough to be an economic venture in itself, but sufficiently often to keep our nose in the market for "best of class" products. A few people have asked recently what we would build "today" (one week before Christmas).

Wireless Internet - A View From the Bottom

We have been blessed with wireless ideas of great promise for a decade beginning with LMDS and Virginia Tech up to the Wired Road and Blue Ridge Crossroads Economic Development Authority. Hope still flickers obstacles remain.

Intel Little Falls Mini ITX Motherboard

Intel Little Falls Mini ITX Motherboard

It's small - 17cm x 17cm (Mini-ITX), green - about 2 amps, capable - 1.6GHz Celeron (Atom) and costs less than $100, With a special north bridge heat sink, it will fit in an extruded aluminum case (suitable for a car also about $100) and can be powered by a wide input DC power supply (6-24v - about $70). You will need a stick of PC2-5300 DDR2 RAM (<$40), a laptop hard drive ($50 and up), a slim CD/DVD (~$30) and the most expensive single component, a touch LCD screen ($300 and up). So for about $800 you can build a rugged, under the dash, car powered, touch screen PC. Geeky teenage offspring or neighbor required.

Ethernet Aliasing for Fun and Wireless Survival

I had a small Technical Epiphany the other day that I wanted to share. I got Ethernet Aliasing to work with Ubuntu Gutsy Linux and it turns out to be quite simple in retrospect. Why might you want to do such a thing? In my case, to tweak my Wireless settings while I used the Internet. My Buffalo AirStation Wireless Bridge was working poorly and I needed status to help debug it. I really wanted to access two different IP networks, without routing, on the same physical wire at the same time without buying a new Ethernet card - which in the dark past would have been the "proper" way to do this.

Knowing alternatives

Knowing alternatives -

Most people wander through life without a sense of living. Sufficient said, "Charles Shaffer is different."

There is strength in numbers. The strong are more than men of might; they are also: the meek, the curious and the cautious, the promising and the pale, the rich and the ragged, and the visionaries. There are not many like Charles; he isn't overly quiet, but there are times when his audience should listen. Charles listens to a different voice — Mr. Shaffer's voice is prophecy.

Wireless Bridging with Buffalo

Everyone seems interested in routers these days. But often Bridging can be so much more satisfying. At home I run a Motorolla DD-WRT wireless router as the firewall and gateway to our cable provider. But how to connect wired Ethernet Computers to this Wireless network .. computers seperated by several hundred feet .. all the way across the house.

One way would be to run wired cables. .. too difficult. Another way would be to buy wireless adapters for each machine .. too expensive. But the way I finally came up with was to run a Wireless Bridge. It happens to be from Buffalo. They make good gear.
