Balance of Accounts

With the great disaster in our minds, and the end of the fiscal year looming, now is a good time to balance our accounts.

How much did you spend this year on goods from companies which oppose you? How much did you oppose them?

How much did you do to help yourself? How much did you do to help others?

RPM Database Indices Corrupt

In response to the error message

error: cannot open Packages database in /var/lib/rpm
error: cannot open Packages index using db3 - Invalid argument (22)
error: db4 error(22) from dbenv->open: Invalid argument
no packages
rpmdb: Program version 4.2 doesn't match environment version

do

mv /var/lib/rpm/__* /tmp ; rpm --rebuilddb

The database indices have become unreadable, for the reason given, and need to be rebuilt. In the above command we move the previous versions to /tmp and allow them to be deleted later if they aren’t needed. Wildcats and BOFHs may wish to simply rm(1) the indices.

Ignorance and Want

Ingorance and Want

In A Christmas Carol, Dickens warns to beware Ignorance, for he is the Doom of Man.

“They are Man’s,” said the Spirit, looking down upon them. “And they cling to me, appealing from their fathers. This boy is Ignorance. This girl is Want. Beware them both, and all of their degree, but most of all beware this boy, for on his brow I see that written which is Doom, unless the writing be erased.”

The tsunami killed more because of ignorance. Many wondered at the strange sight of the seas rushing away from land, and children rushed to play in it. And then died.

Add to My Collection

Amazon needs to integrate with AllConsuming.

But the AllConsuming API doesn’t do PUT, and the Amazon webservices don’t permit modification of the wishlist.

The desired feature is the addition of an item to “my collection,” and the removal of an item from “my wishlist.” Now, Amazon could implement this as a new feature of their service, so that I can maintain a copy of my catalog there, or the LazyWeb could tie the two data sets together.

Population Growth

I don’t recall if I’ve mentioned this before, but if you don’t want more people living where you live, don’t pretend to be fair-minded and make zoning changes intended to control the population growth by decreasing housing density. Be straightforward and honest about it: place a maximum on the population of the area, not the housing density. You’ve been trying to control an effect, not the cause.

Old Photographs of Putnam County

I picked up Images of America: Putnam County the other day while Christmas shopping. I find this series from Arcadia Publishing both interesting and depressing. Interesting, to see what was, and depressing to consider how things might have developed differently than they did. I suppose if I were an enthusiastic admirer of our local built environment, then my opinion might be different, but I think that Sturgeon’s Law applies fully to much of anything built since the middle 20th Century.

Or maybe I’m just tired of having to drive everywhere.

A Fair Shake

Joel Spolsky whips out a copy of Visicalc to demonstrate the economics of pricing, its effect on demand, and price discrimination as the road to profit — or to Hell, as the case may be.

Price discrimination involves altering the price of a good for each customer according to their willingness to pay. Bob is willing to pay $50 for the good, but Alice is willing to pay $25. Our costs are under $25, so we’d prefer to sell to both Bab and Alice, thus maximizing our profit. The classic means of price discrimination are bargaining and auctions. More modern means include different media formats, coupons, rebates, brand cachet, and distinguishing between buiness and residential customers. The problem with price discrimination is that customers feel bilked.

Another means is changing the price over time. Early adopters, the least price sensitive, will pay handsomely, while the more price sensitive customers will purchase the good later, after the price drops.

Where Am I?

My wife is lost somewhere in Pound Ridge. The cellular service is only good enough for a few seconds of talking. This is not long enough for me to find out where she is, but plenty good enough to transmit her GPS co-ordinates. But our phones are too incompetent to do that. They know exactly where they are, so they can tell the snoops and E-911, but they won’t tell us.

On my phone, the LG VX6000, location information is revealed to E-911 by default, but it can tell others. The settings option choices are

  • Location On
  • E911 Only

OK. Now WTF did that do? Nothing.

Perhaps what I’m saying is that all phones, by default, if they know where they are, should tell the holder. Not just this or this or this other party.

The Backlist

Over the past few days I’ve seen references to The Long Tail, a nondescript title which reminds me of a rat, but until reading Gordon Weakliem‘s comments I cared not a whit about reading that article. The long tail is not a rat’s, but the 80% of the curve in a Pareto distribution: the long, shallow end.

The article summarizes the observed effects of eliminating the scarcity of a good. The economics of abundance are paying handsomely at Amazon, Google, eBay, and NetFlix. Goods that would otherwise be marginal, with high physical costs for distribution, are found to have high margins, and not insignificant demand, once they’ve been made available.
