all about bandwidth

Griping about analog modem speed seems quaint in the era of DSL and cable modems, except of course for those of us who live out of range of DSL and cable. Nevertheless, this article is fascinating: It’s the Latency, Stupid.

On the matter of line speed vs. capacity — the distinction that is rarely made or understood — Cheshire writes:

Would you say that a Boeing 747 is three times “faster” than a Boeing 737? Of course not. They both cruise at around 500 miles per hour. The difference is that the 747 carries 500 passengers where as the 737 only carries 150. The Boeing 747 is three times bigger than the Boeing 737, not faster.

Now, if you wanted to go from New York to London, the Boeing 747 is not going to get you there three times faster. It will take just as long as the 737.

In fact, if you were really in a hurry to get to London quickly, you’d take Concorde, which cruises around 1350 miles per hour. It only seats 100 passengers though, so it’s actually the smallest of the three. Size and speed are not the same thing.

On the other hand, If you had to transport 1500 people and you only had one aeroplane to do it, the 747 could do it in three trips where the 737 would take ten, so you might say the Boeing 747 can transport large numbers of people three times faster than a Boeing 737, but you would never say that a Boeing 747 is three times faster than a Boeing 737.

just another lame excuse

Here’s the thing about being first-time homeowners: you don’t really know how to do anything. You don’t even know who to call. At least, I didn’t, so we suffered with ill-fitting doors, and gross shag carpet, and bathrooms “decorated” in realistic splash patterns in every shade of iron (because that’s what was in the water). But over time we built a team of remodeling and construction experts: electrician, carpenter, painter, landscaper, tiler, etc… even a guy named Vern whose specialty is creating gravel driveways without ever getting out of the dumptruck.

This is only our second time in a used house, but previous experience makes a huge difference. We don’t have the patience, or the zero-balance checking account of first-timers. And now, we know who to call.

So, this time, the faded shag carpet only lasted two weeks. The broken irrigation system was immediately repaired and expanded (you didn’t think I was going to spend an hour a day watering the garden?). The water softener will be installed next Thursday.

None of this frantic activity leaves a lot of time for writing, of course. I haven’t set my drums up yet either, or, I hate to admit, even begun to finish unpacking. On the bright side, I don’t seriously expect I’ll ever finish unpacking — so that’s at least one thing scratched off the list.

Fletch Won

Here’s the book: Fletch Won.

the evil stir stick

(By popular demand, I’ve fashioned another story out of our recent septic tank pumping, an experience rich enough in sensation to spawn entire philosophies. Coming up with a measly journal entry was, you could say, a piece of cake.)

As soon as the “wastewater removal” guy opened the tank, a cloud of foul-smelling air rose up to envelop us both, and indeed all of West Sonoma County. I wanted to ask, “do you ever get used to the smell?” (a Fletch reference, I just realized) but I was too horrified to speak, as the guy had dipped down into the tank with his “stir stick” to break up the floating mass of, err, byproducts. Immediately I realized that Manning The Septic Stir Stick is the worst job in the world, narrowly passing Hot Dog On A Stick Employee, the previous record-holder for stick-wielding professions.

The pumper was talkative, perhaps taking advantage of the fact that he was breathing through his mouth. He delivered an impromptu lecture on the origins and composition of the thin layer of funk coating the inside of the tank. Subsequent research indicates that his explanation was completely incorrect, but at the time, even if I’d known, I would not have challenged him, for he still held the evil Stir Stick.

The actual pumping process is not one you’d have to study long to master. Given my physical proximity to the world headquarters of O’Reilly & Assoc., I feel okay about providing this “Nutshell” reference to septic tank pumping:

  1. Don HEPA air filter or oxygen mask if available (optional)
  2. Apply the Stick: break up any large floating mass. If you spot anything you can identify, civility demands that you not mention it to the homeowner.
  3. Lower a vacuum hose into the soup.
  4. Suck the tank dry.

You’ve just earned $330 — enough to invest in rubbing alcohol, boot covers, gloves, leather aprons, autoclave… a coliform containment system so you don’t contaminate your truck’s interior, your pants, shoes, arms, face, and hands with other people’s feces.

Or, like the guy who pumped my tank, you could disregard the need for cleanup and pocket the full payment, blissfully ignorant of the virulent germs running freely over your entire being. I realized that my pump guy belonged in this category when I saw that he had not marked the “up” end of the stir stick. Think that through.

The worst part was still to come. After the pumper had coiled up his hoses and driven away, I realized that having the septic tank open on a breezy day creates an unfortunate air channel: the pipe that feeds the septic tank terminates, at its far end, in my kitchen sink.

Air moves at the slightest provocation, like, even from the wind. This seems especially true when malodors are present. When I returned to the house, having withstood and, to some extent, habituated the great stink in the back yard, I was bowled over by the far greater stink in my kitchen. I guess that was a little going-away present from the pumper, a virtual prepayment for any future tales told at his expense. (As if I would ever do that!)

impedimenta

Contrary to what I told all the folks I was hoping would help me move, I really do have a lot of junk. It was not a light move in any sense. We’d purged beforehand, shredding years of old credit-card statements and tax returns, and driving two carloads of useful but unloved furniture and clothes to Goodwill and the Salvation Army, but even so we were left with a house full of stuff.

Can a pack rat learn feng shui? A friend opines that by accumulating junk, one is expressing doubt that the universe will provide that which is needed, when it is needed. It seems to me if there’s anyone you don’t want to offend, it’s the universe, and so I immediately pledged to offload a large percentage of my accumulations. That was last December.

I still pledge to do that. Really. Erm, do I have to do it right away?

It’s at this point I tend to use a phrase that makes my pragmatic German relations laugh: I like the idea of keeping only the things I currently use… I’m just having trouble with the implementation. I think I don’t have a ton of certifiably useless junk stored away, but I probably do have a ton of stuff I’m fond of but won’t actually ever use. And hey, my new house has a garage. Maybe this is the universe’s way of telling me it’s OK to keep those 10 cubic yards of chattel.

Somewhere, in three of those boxes, are about 250 old science fiction paperbacks from the 1980s… Heinlein, Harrison, Asimov, Adams and so on. All my life I’ve lugged these books along, from apartment to apartment and house to house, with the idea that I’d eventually have a library where I’d display the collection. I find it ironic that, now that I have a room for such a library, I also have a new design sense, or perhaps a lack of design sense, or maybe it’s a sense of a lack of design. In a word, I demand austerity. I want unadorned space. I don’t want empty shelves — I don’t want the shelves in the first place. So I’m pretty sure I don’t want a room lined with the entire Tor catalog, 1981-1985.

I had never seen the word impedimenta before writing this piece, but it’s so wholly appropriate I may actually go re-label all the boxes in my garage.
