Welcome to my home page. I live in New York, NY and Oak Bluffs, MA;
I'm married to Julie; I'm dad to Hazel. I work as a programmer; I have a
dog, and she has a web site too.
Our TV begs to be fed with an HD signal. I did some frantic research
on satellite TV. DirecTV looks decent; it's somewhat cheaper than
Time Warner Cable for similar channels, and looked like it might have
more HD. I never actually called them, but their customer service
couldn't possibly be as bad as TWC.
But satellite would be a bit of a hassle since we live in a NYC co-op.
Even though we're on the top floor and have easy access to places to
mount a dish, we don't actually own our roof, and there would be some
approval steps involved.
With the Presidential Debate and other TV needs in mind, I figured I
would hedge against the cable going dead. I went to Radio Shack and
bought a set of $15 rabbit ears. They're on a little plastic base and
sit behind the TV, with a coax output that goes straight into the TV.
So here's the thing: rabbit ears are great!!! Thanks to digital
broadcasting, we pay a whopping $0/month to get the major networks in
flawless HDTV (ABC, NBC, CBS, Fox, and couple random local/minor
stations). We get a bunch of other digital TV signals, including a
sightly cheesy, but adequate, dedicated kids network ("Qubo"), and a
lot of Spanish-language stations (sometimes good for soccer coverage).
We get a bunch of analog stations as well, like PBS. The PBS analog
reception is acceptable but very obviously inferior to any kind of
cable or any of the digital formats.
The over-the-air HDTV looks quite awesome, a bit better than on cable.
The over-the-air standard-def DTV looks even better (compared to cable
standard-def). I've heard that the cable networks transcode, and of
course they have to make room for the fricking zillion channels of
total garbage in their lineup, so over-the-air wins on picture
quality.
Rabbit ears win in another seeminingly small, but IMO important way --
the Samsung TV remote controls everything, and the channels are in a
reasonable order. With TWC, you get SD and HD versions of many
channels, with the HD versions off in some region of high channel
numbers. Like if you just tune to channel 2, you get low-res
transcoded awful looking 4:3 CBS. The hi def is on channel 802 or
something like that. With rabbit ears, the HDTV CBS channel is on
"2-1", right next to "2", and you can easily delete "2" right out of
the channel list, so you never see standard-def CBS again.
Digital broadcasting also provides a halfway decent built-in channel
guide -- i.e. you press the "info" button on the remote and the TV
shows the name of the show, summary, length, etc. You can go into the
channel list and see the lineup for the next day or so. The TV's UI
is better than Time Warner's too.
There is also the ancillary bug/feature that I will never end up
watching E! True Hollywood Story or The Girls Next Door past my
bedtime. I feel a little bit sad about The Daily Show and C-Span.
But only a little.
This is pretty interesting reading from Paul Werbos; gives an excellent high-level overview of what we're facing:
http://www.werbos.com/energy.htm
Werbos has some good slides
about the near-term future of electric cars. The battery stuff is
interesting, he points out that the new Lithium Iron Phosphate
(LiFePO4) batteries appear to be a major breakthrough. LiFePO4 has
some great qualities:
long cycle life (~2000 cycles)
safe/stable (they don't burn or explode if abused)
high current capability (good for vehicles; you can draw a lot of power quickly to accelerate)
relatively fast initial charging
made of non-scarce non-expensive materials
The only real technical downside that I know of is that they have
lower energy/volume density than some other Lithium technologies.
Their energy/mass density seems to be on a par with conventional
Lithium-Ion but since they weigh less for a given volume, you need a
physically larger battery for the same energy content. But it's not a
major problem; they're still very good batteries.
It looks as though these batteries will be good enough and cheap
enough to make electric and plugin hybrid cars truly mainstream within
the next few years!
Why I'm Against Nuclear Power
A few otherwise-rational-seeming techies loudly promote nuclear power
as a way out of our oil/climate/etc energy problems. They cite some
impressive facts, like its relatively low cost, proven technology, the
fact that coal-burning plants release more radiation than properly
operating nuke plants (due to the trace uranium in coal going into the
atmosphere), and that nuke power plants use a much lower grade of fuel
than weapons.
But, because I actually read the news, I know they are wrong. We
should not be promoting nuclear power. The two basic problems:
Broken ceiling fan? Like to fix stuff? In my case I needed a particular Rhine remote receiver. Rhine is a Taiwan company that
makes ceiling fan remotes/receivers/motor controllers and only sells
to OEMs. The normal dealers mostly don't list individual parts.
Fortunately, these guys
are specifically set up for solving the problem, they have all the
spare parts, you just call them up and read off the exact model
number: http://www.eceilingfans.com/order.html
BTW we've been pretty happy with the
Minka
Aire Concept II, except for that one broken remote receiver.
Jersey Beat
turned me on to a band called
Lemuria, from Buffalo NY. I heard
a couple songs on myspace and ordered their album "Get Better". I've
been listening to it a lot. It's wicked awesome, a little bit like
Jawbreaker meets Team Dresch. Not as frenetic as that would be, but
still hits my spot.
I also stopped by Home Depot. Their stuff definitely fits within my
budget, but none of it looked good to me (let alone, Mrs. Thatch).
I figured I would be back online looking at stuff. My last stop
before giving up was a store right around the corner from my
apartment: Lightforms. For some
reason I was biased against them -- I guess I have an inherent disdain
for the general concept of a lighting store, since I have never needed
one before, and resented the fact that they consumed an entire retail
storefront near my apartment.
Anyway, I walked in, gawked at the ceiling for a few minutes, and
suddenly saw something I actually liked! And it was on the cheap end
of the range! The saleslady was very helpful and turned me on to the
square version of the round fixture that was on display, and had some
advice on sizing etc. For the record, I ended up with the
Tiella
90 at around $90 each.
Score one for bricks & mortar. That said, I want to jot down some of
the semi-decent online contemporary lighting stores, for future
reference:
1. Hillary & McCain are falling over themselves to say it shows that
Obama is an elitist. Really? The two filthy-rich candidates,
whose campaigns have literally been run by Washington corporate
lobbyists, think the other guy is an elitist. The half-black dude
from Hawaii, raised by a single mom, who spent his time prior to
politics organizing job training programs, and didn't finish paying
off his student loans until after the age of 40. That guy's an
elitist.
2. Are any of these looked-down-upon voters actually offended? I'm
sure some patch of
astroturf will
complain loudly, but to me, it's pretty cool that a candidate
actually wants to confront the causes of people's bitterness,
instead of distracting them with a bunch of bull, as per usual.
3. Is anybody else appalled that Hillary's taking up the Republican
talking point here? McCain I understand, it's still totally
ridiculous, but expected. But Hillary? Sheesh.
Anyway, unlike the Wright hoo-hah, this one seems like it could be a
political net win for Obama once people are done processing it.
Here's Obama's spin on it:
(* No, I don't really wear birkenstocks or sip lattes, and
I've been known to bowl.)
What does MP3 compression sound like? Kind of a stupid question
considering that many of us listen to it all the time. But it does
have an answer, sort of.
While I was uploading Sinkhole, I tried an experiment. I compressed
the albums at 256kbps which, for me, is basically indistinguishable
from the original. I took one song's mp3 and loaded it into Audacity
(a nice free audio editor). I took the same song's original .wav file
and loaded it into a second track in Audacity, parallel to the first.
Then I inverted one of the tracks (i.e. reversed the polarity). Then
I zoomed way in so I could see individual samples, and found an
obvious peak in the audio (a bass drum hit). I slid one of the tracks
slightly in time so that the extreme value of the peak was at the
exactly same time in both tracks.
Then I played both tracks together. If MP3 were lossless, in theory I
would hear nothing -- the two sounds should perfectly cancel each
other out, leaving silence.
In practice, MP3 is lossy, and so I heard "what MP3 sounds like".
Huh? Yes -- you can think of an MP3 as just the original signal with
some junk added. I was listening to the junk.
In other words:
Let A = original audio signal
mp3(x) is the signal x compressed and then decompressed by mp3.
So:
mp3(A) = A + someJunk (MP3 is just regular audio with some junk added)
someJunk = mp3(A) - A (I isolated the junk)
it contains a snippet of the original so you can hear what it sounds
like, followed by someJunk.
To me, it sounds like music blasting extremely loud, and I'm next to
some newspaper wrapped around a coffee can full of old screws and
nails. The newspaper and stuff rattle in time to the music, but the
music is so loud I can't hear the rattling at all unless the music
stops suddenly.
OR
Think of MP3 as the original signal with some stuff subtracted. The
stuff that's left out is -someJunk.
My old band, Sinkhole, just
released two of our albums under the Creative Commons
Attribution 3.0 license. This pretty much means you can do
whatever you want with them, including use songs as background for
your intermediate falconry tips video, but more to the point, download
and listen to.
These two albums are the ones on Ringing Ear
Records, the label that we (mostly Jon) ran. We also released two
albums on Doctor Strange Records.
We're checking with the Doc to see how he feels about us putting those
online also. No promises.
