“Head-Up Displays Get Second Chance”

January 12, 2004 - Categories: -Uncategorized

Carmakers and suppliers expect head-up display (HUD) technology to get a
new lease on life with the advent of multicolor light-emitting diodes
(LEDs), smaller liquid-crystal displays, and windshield optics innovations.

committing

January 12, 2004 - Categories: -Uncategorized

The proper thing to do when C-x v v is called and files are modified
depends on whether or not multiple files had been changed. If multiple
files would be committed in a single patchset, one should bring up a
dired buffer containing the modified files, allowing the user to
unmark a few. When the files have been selected, a log window should
appear. C-c C-c in this window should commit the patchset.

I suspect my computer does _not_ keep time in GMT, annoying as heck.

Oh, it does that on suspend.

On technology and lifestyle

About my father

Perhaps he and I are more similar than we thought. I know I am cross
and irritable when my computer malfunctions, particularly when I need
it most, and profoundly grateful to those who help me restore it to a
working state. Yesterday it was my turn to rescue a computer, and at
no time have I been more grateful for the opportunity to be of help. I
saw my father’s face light up when the Vaio slept and woke at his
touch. I heard him laugh appreciatively as the Vaio chimed to indicate
an increase or decrease in volume. I felt the life flowing back into
him, the accustomed excitement returning to his voice. He lived,
loved, _was_ – and I was no longer afraid.

About passions

It is important to me to find a friend with similar dreams. I need
someone I can compete and cooperate with, someone who will help spur
me to heights of greatness. Hacking on Emacs is so much more fun when
I can tell stories about it – another reason why open source community
is so important to me. Trying to improve my teaching is easier when
there’s someone who’ll be ecstatic when I have great class days and
sympathetic when I wonder if we really make a difference.

I want international prominence, and by that I mean I want to
contribute to major projects and get to meet people who are really,
really into working with technology. I want to help people mix. I want
to promote technology. I want to promote _social_ technology,
technology that helps makes people’s lives better.

I thought about crossing fields and helping Eric out, but my heart’s
not really into graphics. I am, however, into funky devices, so am
exploring gesture-based Linux. wayv looks potentially useful, although
still a little raw. Last active development was 2001. Might go into
alternative input and output devices; close enough to my wearables
interest.

A little note about gadgets

I am not into gadgets for gadgets’ sake, and personally I find it hard
to understand why people are into the latest phones “just because”. I
don’t see technology as a way of separating myself from other people.
In fact, I prefer to see it as a way of connecting me to others. I
guess that’s why I prefer my unassuming headphones+audio getup to that
visually impressive but technologically aloof head-mounted display
that people like focusing on so much. With a HMD, other people focus
on technology. When technology disappears into the background, they
can focus on me – and I like that. ;) That’s why I take notes with my
computer under the table. My focus is on the other person, not on the
computer.

Knowing one’s self

January 12, 2004 - Categories: -Uncategorized

Yesterday found us at the Greenbelt mall. Kathy wanted to watch
Buffalo Soldiers – she heard it was a comedy. My dad hadn’t watched
LOTR yet, but tickets were impossible to get, so we all settled for
Buffalo Soldiers instead.

Fifteen minutes into the film, I leaned over and asked my parents if
they minded me going off to Timezone or Powerbooks, as I’d probably
enjoy myself better there.

Got up and left.

After I met up with my family again, my father told me I’d made a good
choice. I told him I’d learned how to cut my losses and run. ;)

I guess that means I’m getting to know myself pretty well. I know what
movies I like and don’t like. I’m not afraid to miss out on a
surprisingly cool movie by walking out on it. I figured that if it was
_really_ good, then they wouldn’t mind seeing it again.

Glad I followed my instincts.

Note to self: It would be really cool if I could rig up a weekly
script to scrape the movie titles from http://www.sureseats.com and
look up reviews in the Internet Movie Database. This script could run
every Wednesday – that’s when they change movies. If I brought my
computer along, then I could just flip it open, check the plot summary
and the ratings… Hmmm. Ideas, ideas.
