Change in your pocket

One of my esoteric interests is currency systems.  For example I wish the feds would stop handing the currency system over to Visa and MasterCard.  This posting by Stan Collender provides a treasure trove of insight into how hard it is to understand the forces at work when you try to shift how a currency system works.   And, it finally answers the question: “why do the dollar coins keep failing?”

  • Retailers decline to pay the extra cost to shipping costs (i.e. they are heavier).
  • The paper manufacture lobbies heavily and generates the usual fog of PR disinformation to undermine their adoption.
  • The vending machine industry demanded to be paid to convert their machines.
  • etc…   it’s a fun read, if your into this kind of thing.

Panama II

Another bad day for Panama, the Northwest passage is open again.

The amount of disruption this global warming thing is causing, it just boggles the mind!

Insurance Deductables

My father was wrong.  I learned at my father’s knee that it is wise to self insure for the little things and buy insurance for the big things.  Thus it is clever and thrifty to buy insurance policies with large deductibles.   It is a little odd to notice that poor people should buy more comprehensive, and hence expensive insurance.  Large economic actors can afford to self insure more than smaller ones; so for example a Billionaire may minimal car insurance – since if he can casually afford to replace the car – but he will carry a substantial personal liability policy since replace his wealth would be harder.   Firms often self insure and some even gin up their own employee health insurance systems.

This advice turns out to be wrong, for most of us.  There are three reasons.  The simple reason: people buy high deductible policies not because they can afford to cover the cost of small loses, but because they don’t have a clue what they are buying.   Secondly the marketing of these things is entirely a pure confusopoly; buyers haven’t got a chance.  But the third reasons is interesting.

Insurance has plenty of adverse selection and agency problems.  Nominally a benefit of self insuring is that your less like to engage in some risky behaviors since you will personally bear the cost.  On the other had you remove any incentive for the insurance company to bring it’s scale advantages to into the equation; e.g. the insurance company is likely to work for systemic improvements that reduce risk.

So there is an argument to be made that my father’s advice might be wrong.  I noticed this because I have a few medical bills on next to me.  My health insurance includes a deductible.  What I notice about these bills is that I am not getting the prices the insurance company negotiated with the providers.  I am paying full price!  Note that agency is not all bad; since agency creates a locus for skill.  In this case I have lost access to both of these.  Having taken the choice to self insure for the amount of the deductible I now have the option to simulate the skills of the insurance company – i.e. I can call these providers and attempt to negotiate a discount … or not.

So this is another interesting story about middlemen.  There are three actors in this story; the service providers, the insurance company, and the service consumers.  I’m am fascinated to notice a new move in the game that can takes place during the negotiation between the insurance company and the providers.  In exchange for a reduction in prices the insurance company assures the providers that it will sell more high deductible policies.  That’s great for the providers since they can then charge those consumers the list price.  To fulfill the promises made during this negotiation the middleman may have to set goals to assure he sells enough of the high deductible policies.

That shapes the market in very perverse ways.  The small jobs become the high profit work.  My father’s advise become obsolete.  How weird is it that purchasing high deductible policies is a form of free riding – since as long as the insurance company price control feedback is working effectively you get the prices and quality provided by that loop without paying for it.

This is all marvelously and distressingly perverse.  Since poor and innocent people tend to mistakenly purchase high deductible policies (do to regulatory failure enabling market failure) this process shifts costs onto poor people.  I also think this explains why the last car I bought had a bumper design that was prone to failure who’s repair was just bellow the typical deductible.  The dealers presumably like that.   The usual feedback loop thru the insurance company that would fix it wasn’t just broken – somebody removed it.

ssh secret server

I wanted to set up a n2n vpn and the way n2n works at this point participation in any given requires that you configure the three things, one of which is a password.  Which means that if you want to ostracize a participant to whom you have previously given these facts you need to change one or more them.  That is inconvenient since it effects everybody in current installed base.

This is a tractable problem if you set up the installed base correctly from the start.  If each participant fetches the n2n configuration using ssh and his identity you your all set.  Just set up an ssh persona (<mr_config_provider@myvpn.example.org>) that provides the configuration when asked and add all participant identities to Mr. Config’s authorized_keys.   Then when it comes time to remove a participant you change the configuration and remove that participant’s ssh key from the set of authorized keys.   Presumably you’d also use the “command=…” feature of ssh’s authorized keys.

Of course in the case of n2n using rotating key files and a cron job to fetch and trigger their reload into the edge is probably a better approach.  But this problem, how to get adhoc secrets distributed to community members, comes up a lot.

“you don’t have a self unless you have a secret”

Kieran Healy joins the fun (or is it nervous laughter) of discussing the way our identities are being forced to collapse into a singularity.

But this is obvious, and I don’t think I’ve heard it called out clearly before:

“In a very deep sense, you don’t have a self unless you have a secret, and we all have moments throughout our lives when we feel we’re losing ourselves in our social group, or work or marriage, and it feels good to grab for a secret, or some subterfuge, to reassert our identity as somebody apart,”

The article that’s drawn from is fun too.

Denaturing the New

This quote from Alan Kay is very nice.  It explains a lot

It’€™s largely about the enormous difference between “€œNews”€ and “€œNew” to human minds. Marketing people really want “€œNews”€ (= a little difference to perk up attention, but on something completely understandable and incremental). This allows News to be told in a minute or two, yet is interesting to humans. “€œNew”€ means “€œinvisible”€ “€œnot immediately comprehensible”, etc.

So “New”€ is often rejected outright, or is accepted only by denaturing it into “€œNews”€. For example, the big deal about computers is their programmability, and the big deal about that is “meta”€.

For the public, the News made out of the first is to simply simulate old media they are already familiar with and make it a little more convenient on some dimensions and often making it less convenient in ones they don’€™t care about (such as the poorer readability of text on a screen, especially for good readers).

For most computer people, the News that has been made out of New eliminates most meta from the way they go about designing and programming.

One way to look at this is that we are genetically much better set up to cope than to learn. So familiar-plus-pain is acceptable to most people.

I observe this pattern often.  The listener is ready and willing to accept some News, but the story I want to tell is something New.  It remains invisible, and while I can denature it until it is impedance matched to their appetite for News I come away frustrated.  Yes yes, rope is indeed very cool; but you have missed the elephant connected to my tale.

you can never say what you will never do

It makes me physically ill to think that the right wing and the idiot media managed to turn this eloquent beautiful speech into baseless acquisition of racism. It makes so angry that some moron in the Federal government decided to fire this wonderful woman. Shame!

This was not chance. This was a malicious act by those on the right. And everybody who went along with it is guilty of the crime. If you are not livid your not paying attention.

Consider this a warning. This is what we have to look forward to after the fall elections.

Sleep late learn more

The results reported here about this Brown Univeristy study have been known since at least the 1970s.  I think I read about them in the 1980s.   They make for an interesting case study in how hard it is to change some things.

“Starting times were shifted from 8 to 8:30. All class times were cut 5 to 10 minutes to avoid a longer school day that would interfere with after-school activities. Moss said improvements in student alertness made up for that lost instruction time.

The portion of students reporting at least eight hours of sleep on school nights jumped from about 16 percent to almost 55 percent. Reports of daytime sleepiness dropped substantially, from 49 percent to 20 percent.

First-period tardies fell by almost half, students reported feeling less depressed or irritated during the day, health center rest visits dropped substantially; and the number of hot breakfasts served more than doubled. Moss said the healthier breakfast probably aided classtime alertness….”

But it’s not impossible, since a few school districts have managed to make the switch.

Squirrels

Some notes on the ongoing battle: squirrels v.s. houses.

The house should be, to the extent possible, inaccessible to the squirrels.  I.e. cut back the trees.   It is mandatory that your seal any holes the squirrels create or discover.

Squirrels are very territorial.  During the spring they fill out the region in a patch work of territory.  If you manage to keep your home unoccupied in the spring your good for the season.  If you eliminate the squirrel that took up residence in your territory it is unlikely another squirrel will move in until next year.   If you capture a squirrel and relocate it, then the squirrel into who’s territory you move it will kill it or drive it out.

Squirrels reproduce in large numbers.  Far more than the landscape can support; so most of them die young.  This assures they almost always fill all available territory every year.  In following a mast year more die, but they are always dying in large numbers.

Catching a squirrel in a trap is easy, but it demands patience and good practice.  They love peanut butter, maybe with a few raisins and nuts added.  You first need to train them that food is appearing, once a day, at what ever location you plan to trap them.  Then place the trap near that location.  Finally, slowly (over a few days), move the small tray your placing the bait on into the trap and onto the trigger.  Once on the trigger you can expect them to manage to steal the bait once or twice before they trigger it.

The kindest way to kill the squirrel you have trapped is to place the trap with squirrel into a large box.  Then, place a tea kettle containing water and dry ice into the box.  Finally, seal the box reasonably tightly.  The dry ice will be converted into carbon dioxide, which will put the squirrel to sleep, and then kill him.   Of course since you can’t predict what day your going to need the dry ice on, you will want to have already planed out how to obtain the ice quickly.

The most convient way to kill him is to transport him into another squirrel’s territory and delegate the job.

Do not kill the squirrel if you have any reason to believe it’s offspring are currently residing inside your house!  Don’t seal the holes with the squirrel inside!

Finally, watch the funny video.

Happy Birthday Mr. Blog

The Blog was apparently the eight years old on the 22nd.  He has been pestering me for a content distribution network but I’m afraid that will have to wait for another year.

Happy Birthday kid!

I’ve enjoyed having your around more than I ever expected I would.

FYI – I will be in paris tomorrow for a long week.  It looks like it will be over busy, but if anybody would like to hook up maybe we can make that happen.
