The future of big cameras

D800

Yesterday Nikon announced their new D800 digital SLR.  The headline feature that everybody is talking about is the 36 megapixel 135-format (36x24mm) sensor.  If it performs as expected, it’ll offer image quality comparable to a $15000 digital medium format system, in a camera half the size and 1/5 the cost.

The D800 is of course the slightly-delayed successor to the D700, a camera I’ve been happily using for more than 3 years.  My D700 has been up dozens of mountains, seen hundreds of trails and been to Europe twice in that period, wracking up a little more than 60000 shots in that period.  In addition to offering triple the pixel count of its predecessor, the D800 adds high definition video capture, dual memory-card slots and a 100% viewfinder and even manages to lose 10% of the D700’s weight.  All for the same official price that the D700 sold for when it came out.

The D800’s problem, if it can be called that, is that there are a lot of good cameras available these days.  Not that the D800 won’t sell tremendously well of course, but the fact of the matter is that for many, I daresay most, applications, the existing options are well past the point of ‘good enough.’  The main advantage of 36MP over 16MP or 12MP is that you can print larger, or crop more.  Don’t do either of those?  Then a camera half the price and half the weight will likely serve just as well.

For my part, much as I’ve enjoyed my D700, I’ve gotten somewhat tired of lugging it around.  With a good lens, the kit is over 4 pounds, which is to say too much to bring along casually.  The size also makes it intimidating.

Looking ahead, it’s fairly clear that smaller cameras are going to continue to improve.  While the absolute gap in quality and capabilities between small and large cameras may remain the same, the relative difference will continue to become less important.  The number of people who want to print 11×14 is larger than those who want to print 16×20, and that still larger than 24×36.  Likewise, the number of people willing to pay for a camera that goes to ISO 25k, 50k, 100k and 200k drops substantially at each step.  The cost and convenience of the smaller cameras at a certain point will be compelling enough that all but the most die-hard technology junkies will jump off the upgrade bandwagon.

So in some sense, I see the D800 as the beginning of the end.  It’s a great camera, but an evolutionary dead end.  In a future where quality requirements have been met, convenience and connectedness will be the most important metrics, and in that future there will be only a small niche for the large black bricks that we call cameras today.

Installing xv6 on MacOS X

Qemu

For the OS course this semester, we’re using xv6, a simple operating system based upon Unix System 5, but rewritten from scratch for modern hardware and compilers.

The process for building xv6 on MacOS X is slightly more involved than on other systems.  It took me a few tries to get it right, so here it is.  These instructions are for MacOS X 10.7 (Lion), although they should be similar for other versions.  They’re based on the original MIT instructions.

Behind Schedule

After a surprise storm in late October, downstate New York hadn’t seen any real snow until yesterday.  Admittedly many people prefer it that way (it sure makes driving easier), but I’m of the view that you can’t have a genuine east coast winter without the stuff.  Besides, without the snow the countryside just looks bare and dreary.

For now though, winter is back on schedule.  There were even people out skiing at Rockefeller State Park.

In Memory of Carol

Today I went to the memorial for Carol, one of my grandmother’s best friends.  Carol passed away last month after a long illness.

It’s hard to know what to say at such an event.  Words seem painfully inadequate.  She was an extraordinary person in many ways, but above all she had a knack for bringing cheer and joy wherever she went.  In our hurried, impersonal world, that is indeed a rare gift.

One of the more poignant moments at the memorial came when her close friend explained that Carol had said previously that she didn’t want any memorial to be held.  “I know.  But it’s not for you.  It’s for us,” the friend replied.  And it was.

Goodbye Carol.

Site anniversary

It’s hard to believe that I made my first post to this site’s predecessor (myownlittleworld) exactly ten years ago.  The site has had its ups and downs since, much the same as its author, but I’m hoping it will still be going strong ten years from now.

Looking back at old posts and the memories they conjure up, I recognize the skinny, sharp, cynical, occasionally confused kid who posted his musings on these digital pages.  I’m not sure quite what he’d think of the current version of me, but I hope wouldn’t be too terribly disappointed.

And if I could send a message to that fellow (not that he would have listened!) what with hindsight being a benefit and all, it would have been: Don’t take yourself (or anybody else) so seriously.  Life is just too short.*

*Seriousness is a leading cause of chronic overcautiousness among other damaging neuroses.  Such a condition, if untreated by ample quantities of levity and silliness, frequently degenerates into a state known as ‘being a tiresome bore.’

They Deserve to Lose

I try to avoid saying too much about politics.  This is partly because most of the time others have already said what I would have said, and said it better than I could have.  In truth though, I steer clear of political posts because I really have nothing nice to say, and who wants to be Cassandra anyway?

Still, given that the 2012 ‘election-cycle’ is almost upon us, and given the absurd spectacle we are now greeted with, now seems as good a time as any to say what I think, and what I think (writ large) is:

The Democrats deserve to lose this election.

Winter Daze

In spite of the early snowstorm at the end of October, it’s actually been a very warm winter here in New York so far.  Feels a lot like winter on the west coast, except warmer.  On the bright side, the days are starting to get longer, albeit very slowly.

Here is the view from lower Manhattan on a gray, blustery morning.

Stormy skies

Air Travel

It’s no big secret that air travel in general has become a lot less fun than it used to be.  Shrinking seats, escalating fees, and of course the ever-increasing list of ‘security’ procedures foisted upon us by the good folks of the TSA and the Department of Hopeless Stupidity.

The whole situation seems to have disintegrated long past the point of parody, with disabled toddlers being groped by TSA agents and holiday cupcakes being confiscated as contraband, but there we are.

strlang

strlang – a simple language for string manipulation

strlang is a programming language I created with the goal of making string manipulation simple and straightforward.  It is an imperative language with a minimalist syntax.  The language and its compiler were written as part of the Programming Languages and Translators (COMS 4115) course at Columbia University in Fall 2011.

Features

  1. Basic data types are strings, numbers and maps (sets of key-value pairs)
  2. Full-set of operators for arithmetic, string manipulation (including basic regular expressions) and map construction
  3. C-like structure including functions, loops, conditionals and expressions
  4. No keywords

Winter Revisited

White Mountains

This photo is from last year, descending White Mountain Peak in eastern California in the middle of October.  Meanwhile it’s 50 degrees and sunny outside my window here in New York in mid-December.

One of the benefits of being on the east coast is that we do have four full seasons.  Of course as my photo suggests, you can have seasons in California too.  You just may need to drive to a different part of the state to see them.
