30 seconds worth of rotation is more than you think. I've tried taking the typical star trails shot by stacking a bunch of 15 second exposures together. I got the star trail alright, but when you look close they're dashed lines. I can see the rotation during the 15 second exposures and then the darkness of the rotation during the 5 seconds that was occurring between exposures. My tails look like "-------".
I believe that the US Post Office should take the lead here. Even 10 years ago, I thought that the USPO was the perfect "official" entity to manage keys. The post office currently serves a sort of official role in guaranteeing safe deliverly of your mail (more or less). If the USPO had official processes for proving you are who you say you are and keeping your public key, then the US Government could safely allow digitally signed emails to represent contracts, etc. Once you reach that point, it seems like signed emails would become the norm for business transactions. Furthermore, once you have all the keys and government endorsement, it seems like encryption would follow very quickly.
Even better, it would become trivial to filter out any non-signed emails as spam, and for any signed spam to be prosecuted.
Why is Email "time sensitive"? I think I can wait 5 more minutes for the next Viagra add to show up. Even if it's important email, who cares if it gets delivered now or 5 minutes from now? In fact, the protocol itself expects to be prioritized low, thus the retries.
I think it's interesting that the lessons you have listed are all about the real world interaction that you had with other players and not about the virtual interactions that your character had with other characters. There was at least one reply which listed lessons from the virtual world and I found myself doubting their validity, because, well, it's not real. Anything someone claims to have learned in the virtual world is questionable because "characters" are NOT "people", "projects" are NOT "raids", "loot" is NOT "cash", and most importantly "losing" is nothing like "dying".
There's a project that does "captcha" with text questions, which makes it usable by the blind, and probably less likely to accidentally deny access to humans. Of course, spammers might be able to attack this as well, but if they can get 90% on an image captcha, then maybe this is worth trying.
I've noticed more and more "product blurring". I'm guessing this is when they couldn't come to an agreement with a product advertiser. This really bothers me when I notice it.
Leapfrog isn't that dumb. We have a centipede that has a letter on each leg. It will pronounce the letter when you touch it or pronounce the sound that it makes. Being creative you can get it to say a couple of words by hitting letters in succession. Being a mature adult, I immediately tried to get it to say dirty words.:-) I was being so clever. "Look honey, I can make words, F U S says 'Fuss'" Then I tried, F U K and it giggled and said "That Tickles"! No kidding, really!
But I have to agree that anything the size of a pen gets lost within a week, even for some adults.
Did anybody else notice the paint job on the demonstrator. It has a black line down the center with an N-shape in the middle. It has a red line down the center with a similar but less pointed N-shape in the middle. Clever. A before and after view of the sonic-boom wave-front.
It seems
like every movie these days has a million
somethings in it just because they can. Think
about it for a moment, I find myself going "Oh
no, not again" everytime I watch a movie with a
million somethings. I think I've started to rebel a bit. I may end up watching chick
flicks just to avoid the overboard effects.
I think this is a repeat of the lessons we've learned
with synthesizers in music and fonts/colors in documents. At first, everyone feels compelled to use them, the result being judged by the quantity
of the effect, then eventually we return to the base skill. Documents rarely use 10 fonts or colors these days. Well, music is still sometimes about who
can make the weirdest sound, but some are finally
returning to making good music.
The referenced articles says "...the number of paying music downloaders doubled in the first half of 2003 -- coinciding with the [RIAA] announcement that they intended to begin prosecuting file-sharers..."
How ignorant. The RIAAs litigious behavior has
nothing to do with it. Paying downloaders increased because
sites offering to sell music increased.

Is there a way to incorporate the techniques of
open source into a CS classroom? Come up with a
program that does one simple thing, then pass it
around the class and assign enhancements to be
added by each person. Perhaps several such projects
circulating simultaneously.
Then again, maybe this would only be appropriate
for higher level courses. In which case you should
give them a CVS repository and have everybody add
their part simultaneously.
Anyway, I'm just thinking of ways to incorporate
modern practice into the classroom. How many
times have any of you started from scratch for
a new program?
I use to work for IBM and they would regularly have the IP lawyer (That's Intellectual Property of course, not Internet Protocol) come around and "beat the bushes" for patents. They'd tout how they have more patents than anybody else and how that gives them leverage at the negotiations table for cross-licensing.
I sure felt like they were asking for you to patent stuff that shouldn't be patented. At least, they were asking you to put in the paperwork if there was any doubt and they'd decide.
I got a bonus because a coworker did all the legwork and filed on my behalf (so he'd get a bonus too). But the whole time I was just shaking my head and saying "This would be obvious to anybody that encountered the same problem."
It's sad that x10 can only make money on cameras
(and using sleazy advertising). www.smarthome.com
is more focused on home automation but it's still cool.
I've seen the "ultimate linux box" articles
before. What I wish they'd write is the
"affordable and reliable linux box". In
other words, just tell what's a good sound
card for linux, a good video card, etc.
We seem to value things similarly so I'll
share my reasons for buying a PS2.
Nintendo seems to have really raunchy
business policies. Suing people, compromising
design decisions to protect license fees, etc.
X-Box is...well... Microsoft.
The PS2 plays PS1 games. This alone is such
a novel thing in the video-game market that
I want to vote with my dollars for them. And
they seem to be more welcoming to developers.
And they seem to be prepared to make the PS2
integrate with the rest of the entertainment
system and with a home network.
My "why" is because it's in my living room,
next to my stereo and my TV. If I can get
it connected
to Ethernet, wired to my home network, and
playing mp3's off of a samba mount, I'll have
my networked jukebox without buying any new
hardware. It'll be a game machine,
a dvd player, a cd player, a networked mp3 player,
a web-browser, and even a home-automation terminal.
We need a better plan. I've heard the arguments
(legal, ethical, etc) against retaliation,
auto-patching worms, etc., but the same old
passive way of dealing with this aint working!
Here's a plan: How hard is it to set up
collaborative filtering? If.1% of us setup
some software to report infected (and attacking)
machines to a central location. Then when we
get several reports on an IP we just need to
find the closest router to him that is
cooperating with us and black hole him. Okay,
maybe just for a few hours at a time.
For the time being, I'm sending URLs back to
the originator that might disable him, might
fix him, or might just notify him. Then I
black-hole him on my server. This seems to
be helpful because it's frequently a repeated
attack.
Someday, will it be acceptable to make an
anti-virus? That is, a good virus which infects
and fixes vulnerable and/or compromised systems.
Clearly an anti-virus could be made friendly so
as not to do undesirable things, but currently
this would be frowned upon (and probably illegal).
It seems like this would be the quickest way to
put a stop to worm after worm after worm.
I do not have a NN running my house but I do
have some X-10 stuff being coordinated by my
linux box. I use the
MisterHouse
software, which has plenty of unused potential
in my case. Although my system is currently
pretty simple, I have spent plenty of time
thinking about the system I want to build.
I envision a system largely based on states and
transitions. I.e. if no one is home, the next
logical transition is someone arriving home. In
the evening when watching TV, the next logical
transition is everyone goes to bed. Then what
happens when motion is detected in the hall is
based on whether we were watching TV, in bed,
or out of the house, etc.
I can easily see the application of fuzzy logic
to detect these states and transitions. I have
some code which you might be able to call fuzzy
logic already that decides whether or not hall
lights are necessary, but this clearly doesn't
approach the complexity of neural nets.
The problem as I see it is the writing of the
rules to detect these states and transitions.
I'm a bit overwhelmed by the prospect of writing
rules to predict "bedtime" when it might involve
season, holidays, tomorrow's appointments, the
activity level of the previous day, etc. Can't
a neural net be used to infer the relationships
between all these things?
Another thing that I thought NNs were good for
is coping with unreliable inputs. You can read
with only one eye, you can walk with a bum leg,
you can understand speech even in a loud room,
etc. This aspect of NNs seems applicable to
home automation. If I have a NN trained to
recognize when I'm watching TV, maybe it won't
freak out when I get up and go to the bathroom.
Maybe it'll figure out that I went to bed
even though the battery is dead in the hall-way
motion detector, or more likely with X-10, the
indication of motion was the victim of an X-10
collision.

Except that now the movies that show on the premium movie channels have product placement in them.
It was funny and sickening at the same time, but The Truman Show made light of product placement.
