http://enthusiasm.cozy.org Ben Hyde Wed, 27 Aug 2008 13:33:34 +0000 http://backend.userland.com/rss092 en I skimmed the book Control through Communication.  The book is about firm size.  As we learned to manage information and communication at larger and larger scales the size of firms grew.  Which is all fine, but the aspect of the book I enjoyed was the schemes and gadgets.  Mostly the gadgets.  At one point the boss managed his communication with grid of pigeon holes, one for each day.  This scheme evolved; getting larger and larger until you could buy single unfolding desks, the size of a modern SUV, with hundreds of pigeon holes. This picture shows the Dupont executive chart room.  Using charts to illustrate the status of the firm's many operation was, at some point in time, an innovation.   About the same time Dupont started to use crude modern financial modeling, ROI and such.  Somebody at Dupont was sufficently enthusiastic about charts to have this marvalous contraption built. The executives would sit in those chairs shown in the foreground, and as each portion of the operations came up for review their assistants would slide forth the handful of charts illustrating what's happening with that.  It reminds me of a dry cleaners. On theme in the book is how the meer idea that information should flow up and down the corporate hierarchy was innovative.  And then that these communications would become formalized was yet another.  I don't know if the word innovation, rather than say enivitable, is the right term.  The book disappointed me, but then I only skimmed it, beacuse it doesn't really engage with the two questions I'm interested in. First how did firms manage the puzzle of how to negotiate out what should be communicated and how hierarchtical that communication ought to be.  It was interesting to realized that the the practice of highly hierarchtical communication may well have emerge almost entirely because that was what the technology could support.  The complexity of printing and it's scaling characteristics meant that the central office could execute communication acts that the periphery could not.  If so the xerox machine must have created a bloom of lateral communication. Second how much did this wipe out smaller businesses.  Was this really a major driver to the condensation where single large firms displaced smaller firms.  The roll up that happened in the telephone industry reprised in multiple other industries; but it's a provocative thought that it happened for almost identical reasons: communication based network effects. These two questions interact in some cases.  When railroads merged the operational rules of the dominate player would have to displace those of the weaker one, and in many case the stronger one had more effective communication and control schemes. Looking at that picture I'm reminded of a reporting framework that a new senior manager once deployed into a firm I was working at.  The frame work was extremely standardized, N slides, M panels in each slide, with rules about what was expected in each slot.  It wasn't a bad scheme, and it certainly made his job much more efficent.  Which was good because ... http://enthusiasm.cozy.org/archives/2008/08/chart-room I've been trying to think about the financial structures around processes that exhibit highly skewed distributions.  The insurance industry is a great place to find the examples.  We buy insurance to hedge against the small but awful.  Most of our houses don't burn down, but it does happen.  The chance of a fire is scale free, the insurance company protects it's clients at the scale they care about, but who protects the insurance company against the rare event the burns down the entire town.  There are three ways the insurance industry handles that scenario: they don't cover it (excluding acts of god for example), they reinsure into a yet larger pool, or they avoid it by not insursing in certain venues. Over here at Bronte Capital is a posting arguing that Warren Buffet, who moved into the insurance industry in a big way over the last few years, has been working this third angle. When process with a highly skewed distribution delivers it's rare but powerful shock into the system, it's black swans, everything designed to work with the median shocks is blows up.  I'd be interested to know how the insurance industry handled the New England hurricane of 1938.  I'd be interested to know how the insurance industry in Thailand handled the AID's epidemic. Another place I've been musing about exceptional, but inevitable, events is where you situate your career planning.  I've a friend who likes to say that almost all the people he knows who made a fortune in their life "fell of a log into a pile of money" thru no special merit of their own except in some cases they consciously picked a good log to sit on.  On the other hand a lot of people just fall off a log sooner or latter.  It would be nice if, as you plan your career, you had a better sense of what the chances are in the trade you pick, in the economy at large.  The fetish people have for presuming that career path probablities are entirely a matter of personal merit seem wreckless.  I was quite impressed when an acquantance of mine with a degree in biology explained he was moving into lawyering because, well he didn't put it this way, the climate was more predictable. Recently I've been trying to explain how wily US cell phone pricing is.  They sell monthly plans with N minutes and then when the exceptional crisis comes down the pike, you fall in love example, they charge you huge over charges.  The typical plan delivers minutes at about five cents each and forty cents a minute.  Better, at least for them, is that as little crissis come and go your start changing your plan to buy more minutes, which in the absense of a crissis you don't use.  That in turn raises the real cost of even you noncrisis minutes.  It's a very impressive pricing scam isn't it!  I recomend prepaid (t-mobile for gsm, pageplus for cdma on verizon). If we ignore prepaid cell ... http://enthusiasm.cozy.org/archives/2008/08/blow-up-rich WANs are wide area networks, like the internet, and LANs are, local area networks, like the wifi in your house.  PANs, personal area networks, are - i thought - a joke.  Presumably each Borg has a PAN so his headset, pda, cell phone, and ankle bracelet can talk to each other and when he sits down in his car the engine, radio, gps all join in. So imagine my surprise when this weekend I found I was creating a PAN using Bluetooth.  Bluetooth is a standard full of promise which seems to specialize in delivering a frustration.  Two things lead to that frustration.  First there is lots of bad hardware.  Chips that don't work very well, headsets that sound awful for example or software stacks that are buggy.  Second the standard has volumes of optional bits and peices; so usually it turns out the two devices you want to talk to each other don't happen to support the necessary bits.  Sometimes that's intentional, for example you can't use your phone as a handset to talk to your computer since that would let your route around the cell phone company using voice IP.  The structure of the Bluetooth standards with all those optional bits and peices is typical of telco standards. The fun I had this weekend was discovering that this phone I got and some of my Macs support Bluetooth PAN, one of those optional bits.  Using this it was trivial to let my Mac talk connect to the internet connection that the phone provides.  One, two, three: Do the usual bluetooth pairing, select connect to network from the bluetooth menu, oh ... there is no step three. In theory Bluetooth PAN supports multiple devices sharing the internet connection, but apparently my phone doesn't do that. This worked trivially on a MacBook Pro running Leopard.  But sadly it does not work on the MacBook Air - which in a typical Bluetooth user experiance - pretends to support Bluetooth PAN but it is unusable slow.  So for that machine I'm forced to switch back to more traditional Bluetooth DUN (dialup networking - a simulation of the dialup modems of my childhood). I got into all this because I've been wanting to try AT&T's $20 a month "unlimited" prepaid internet.  Right now you can buy a Z750a for $60 from their prepaid store - and if you poke around you can find online sites that will send you a rebate (after 90 days) of $25 or $30.  If you pop in $100 then the phone is good for year (buy from CallingMart with a coupon). I don't intend to make any phone calls so that's five months of internet access.   The Z750a supports Bluetooth PAN, DUN, and it can be a remote control for you Mac (I recommend declining all the options you don't need).  If you buy the USB cable it's a bit faster; but the G3 HSDPA over bluetooth is pretty nice as it is.  The USB cable appears to charge the phone as well. This ... http://enthusiasm.cozy.org/archives/2008/08/bluetooth-pan Evernote is a cool idea.  They want to enable you to keep copy of all those random notes.  In this example I drew a quick sketch on an index card (on this topic).  I held it up to the little video camera on my Macbook and took this picture. Then I dragged the resulting image into their application, and sychronized to their server.  Less than a minute later I syncronized again and they had run a bit of hand writting recognition over my sketch.  Not all, but some of the text was now searchable. It works pretty well for business cards too.  Fun. http://enthusiasm.cozy.org/archives/2008/08/evernote From Chapter 2 of the "Transportation Energy Databook" from the US department of Energy (with slight format changes).  The Commercial air numbers maybe high do to freeloading cargo.
