On Infrastructure
-----------------
There is one system, not a collection of systems.
The desired state of the system should be a known quantity.
The "known quantity" must be machine parseable.
The actual state of the system must self-correct to the desired state.
The only authoritative source for the actual state of the system is the system.
The entire system must be deployable using source media and text files.

Example programs and tests for the POSIX Asynchronous file I/O

There are some tests ripped out from git://repo.or.cz/ltp-debian.git/testcases/open_posix_testsuite/conformance/interfaces and made self-containing. They demonstrate and can be used to test the POSIX AIO interface for asynchronous I/O and formerly file IO.

Build with a c compiler (for instance clang or cc):

cc -o aio_read-test aio_read-test.c && ./aio_read-test

Note: Contrary to popular belief, it has been tested and confirmed to actually be asynchronous on Darwin 10.6.0 (xnu 1504.9.26~3).

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

Don't use MongoDB

I've kept quiet for awhile for various political reasons, but I now feel a kind of social responsibility to deter people from banking their business on MongoDB.

Our team did serious load on MongoDB on a large (10s of millions of users, high profile company) userbase, expecting, from early good experiences, that the long-term scalability benefits touted by 10gen
