Re:Only 7 Years?
The article originally said:
...This article should really be called "7 Years of 3D Graphics" because 3D acceleration seemed a suitable starting point...
So yesterday I emailed the author pointing out that accelerated 3d graphics has a 30 year history at Evans & Sutherland and a 20 year history at SGI (see for example this timeline). He replied that this was true and then changed the wording in the article to say:
...This article should really be called "7 years of PC 3D graphics in the home"...

Re:What should they learn from SSN abuse?The Social Security card is a piece of paper which asserts a binding between a name and a number. It's not a reasonable form of identification at all, and that's why it says "not for identification" right on the card.
They said "not for identification" years ago, but the ones being issued now do not, nor have any for at least the last ten years. See this for a little on that.

Re:Taxonomic Database
Many people are dealing with these problems. They are actually relatively easily dealt with in RDMSs...for the most part. Check out the hymenoptera database at Ohio State. There is a data model burried in there somewhere. Also check out Species 2000 (Kansas) or Mandala out of Illionois.
-
Re:indexing the database?
If you were a *entomologist*.
You hit the nail on the head. You have to do *lots* of background of research. Then follow all the rules of the zoological code of nomeclature. MANY MANY species are named more than once, sometimes very many times. To find out the proper name is very taxing (pun intended).
There are numerous databases that are begining to store all this nomenclatural information, its and exciting time to be a taxonomist. The use of DNA will come in time. DNA is completely useless in the field at this time..you still have to know morphology when you are out on the hunt. It is important to note that nobody is going to fund you to develop assays that can identifiy species IN THE FIELD using molecular techniques unless you have very economically important species . This work has to my knowledge actually never been done (for insects). -
CIS at Ohio State
I still am in awe of what our CIS department has done at Ohio State. They handle something like 200 thin clients, plus all the remote sessions.
Basically, you sit down at an old, stripped down HP-UX machine or a thin client that allows you to log into one of their servers. NT and Solaris are the typical flavors--I can't remember what the other option was. Plus, if you log into the Solaris box, you can open a Citrix client and use that to be logged into an NT server. This is really nice for writing code in UNIX land, but using MS Office for the documentation.
I would just love it if the EE department could get a clue and do something similar. It really would give us the best of all worlds. Oh, and you can read more about the CIS setup here. -

CGI existed before the 60s...
You're somewhat misinformed then. Some of the first computer generated images were produced in the early 50s on vectorscopes, and were used in the first CAD at that time. By the 60s, CGI was used for movie intros (Vertigo, 1961.) The first computer art competiton was in 1963, as was the first computer generated film. For more info, see the historical timeline of computer graphics and animation.

Why Toilet Bowl Water Twirls ClockwiseFrom http://www.discovery.com/area/skinnyon/skinnyon97
0 523/skinny1.html:fictitious force, n. Coriolis isn't even a real force, since it doesn't make anything speed up or slow down -- it only explains why things appear to speed or slow as the world spins out from under them. This sort of impostor is known as a fictitious force.
From http://www.physics.ohio-state.edu/~dvandom/Edu/new cor.html:Water in the sink doesn't go far enough to trigger a noticeable north/south deflection. Most often, it simply spirals down the sink the way it went into the sink, and the same is true of things like the famous "demonstration" of the Coriolis force shown at tourist traps along the Equator. Maybe there's a conspiracy to manufacture right-handed sinks in the Northern Hemisphere and left-handed sinks in the Southern Hemisphere?
In any case, don't blame it on the Coriolis force unless your sink [or toilet] is the size of a small ocean. -
Not all uses are medical
Ultrasonic testing uses sound waves to detect imperfections in material and to measure material properties.
Ultrasounds can be used for testing material imperfections in other things besides people (though of course things like x-rays are better and are often used on non-living objects). All the same, I'd be interested in seeing how cheap this is. If it's significantly less expensive than previous ultrasounds (and it looks like it might be) then drop in cost can make a lot of things 'possible' that weren't before. DNA fingerprinting was possible before PCR in 1992, but PCR made it cheap enough for common use.
Ultrasound does have engineering applications
"The comparison between the original and final thickness converted to strain readings and plotted on thickness strain diagrams. The thickness is measured by pointed micrometers, or by ultrasound gage. From the final thickness and original thickness ratio, TF / TO, an actual strain level can be developed based on constant volume and plotted on a thickness strain diagram." (Hogarth, D.J., Gregoire, C.A., Caswell, S. L., 1991, p. 88).
http://nsmwww.eng.ohio-state.edu/Stamping_Glossary /html/t.html
Abstract: Circulation calculations, which have traditionally been performed by taking the line integral of the velocity around a closed path, require detailed knowledge of the flow field. An ultrasound method for circulation measurements has been under development at WPI for several years and it has the advantage of allowing for the direct measurement of circulation without the need for the velocity field data. This time-of-flight method employs counter-propagating ultrasonic pulses. The time difference between the counter-propagating pulses around the closed path is linearly proportional to the circulation enclosed by the ultrasound path. The ultrasound method of circulation measurement does not require any calibration constants and can be non-invasive. The reliability of the method was assessed by comparing the directly measured circulation values with those deduced from the lift of a symmetric airfoil. Examples will also be presented where the ultrasound technique has been applied to the vortical flow over a delta wing and a tip vortex. Owing to its simplicity and ease of operation, the technique may be utilized in the future as a sensor in closed-loop active flow control systems.

I'd agree with this....
If it worked both ways. If I owned, say microsoft.org, it would get taken from me even though MS is clearly not a non-profit. The fact is, the original definitions of what TLDs meant is lost in the current system.
See the dispute over WWF.com. The World Wildlife Fund sues the World Wrestling Federation for the domain wwf.com. Now, since the World Wildlife Fund is a non-profit, and already owns wwf.org, and the World Wrestling Federation is clearly for-profit, where's the dispute? Under RFC 1591 each party has the correct domain.
Of course, the WWF (wrestling) has abused the UDRP themselves in the past, but the my point is that actually following the traditional definition of the TLDs is not something the arbitrars care about at all. -
port 59 is the "well-known" port for "NFILE"
which, I might add, I'd never heard of before doing a suitable google search. If you're curious, the NFILE rfc can be viewed at http://www.cis.ohio-state.edu/cgi-bin/rfc/rfc1037
. html. Basically, it sounds like some sort of strange FTP analog (from the glance I took @ the abstract). Publish date was '87, so this is a relatively old protocol, that from the sound of it hit the dustbin of history with a loud "thump!" ;-) (The 'any private ...' bit may be from NFILE's predecessor, QFILE?) -

some similar research at Ohio State

Re:Corporate America steps up to the plate
I would have to say that they do. Librarians are right behind IT professionals in making the information age work. In fact, a good number of IT professionals are IT professionals. Some of them believe in open source too. A great example is the Prospero document delivery system. It's a set of Perl scripts for Apache with a Windows front end done in C. And it saves thousands of dollars over the competition.
Librarians are much more than just little old ladies (and even many who actually are little old ladies have quite impressive computer skills). And they provide a valuable service to keep information--in all of its forms--freely accessible for the public to use now, and for years to come. They are most definitely on our side in this fight.

Re:E in E
Yes, we used those back in my "Gateway Engineering" year at OSU. This is now called "Honors Engineering" One of the elements of this year long integratedengineering first year is a robot design project in which you have to build a robot with an erector set and a handy-board.
There is information and some pictures of erector set based robots
here
Mine was the first year to use erector sets, which were chosen since they were cheaper than lego. I think that my group was the one that fried a handy-board on the robot's frame, then came up with the mandatory cardboard shielding for the boards (non-conductvity would be an advantage of Lego)

Re:Trademark holders are the squattersStrictly speaking, the original intent for the
.org was pretty much "other" To quote from RFC 1032:
"ORG" exists as a parent to subdomains that do not clearly fall within the other top-level domains. This may include technical-support groups, professional societies, or similar organizations.
Although this implies other than corporate, government, educational institution, military, or network op's, the more specific idea of .org being NPO came a bit later. -
Useful stuff
It would be great to know how they implemented the monitoring in order to apply it to other useful daily needs. For example:
- HTCPCP: Hyper Text Coffee Pot Control Protocol (RFC2324)
- Coke machine monitoring: I remember the frustration of being in the computer lab, willing to get a cheap coke and having to go to the next building (coke next to the computer lab was damn expensive) and then finding NO COKE in the coke machine.
-
Re:In what way is it different?TCP can't "broadcast"... it's for bidirectional links.
Yes it can. It's called Multicasting, RFC 1112.
However, multicasting requires cooperation from all the routers between the source and the target audicence, so it doesn't generally work too well over today's internet.

LEGO Killed the Erector Set
I'm just barely old enough (okay, I'm old) to have missed LEGO's for the most part. I got to play with Erector Sets! Now those were Real Toys (TM). We were too poor to buy the one with the motor, but I got the one just below it for Christmas. Started out building the stuff in the pictures in the instruction book, but ended up making spinning fan-like objects that could cut fingers in a flash. Oh, and guns, of course...
OMG, it looks like it's coming back!
This page brings back memories... oh yeah... -
Re:What's new?
Forget ten years ago. Ameritech messed something up in the 614 area code and several number ranges (614-45x-xxxx, 614-26x-xxxx, and 614-29x-xxxx, check here). I'm lucky NOW to get a 9600. Usually it's about 7200. Yes, bps. And then only to one ISP.
(Perhaps someone else has had similar problems. It's been like this for over two weeks.) (OT: Where's my sig? Maybe stuff's still messed up in Banjo or I need to enable something.) -
Umm...what's all the hubbub?
How to do this is already public knowledge and it's being implemented on a wide scale. Even Windows can do it (though no one knows when it will be able to do it correctlye. Look here.

Non-IssueI'm a Verizon DSL customer, and this is an utter non-issue. For ~ $25/year, I have my own domain through a DDNS provider and I just run my own mail server. No sweat, and a good deal more reliable than Verizon's has been over the past year.
For the students who are suffering because they can no longer claim to be @foobar.edu when sending through @verizon.net, may I suggest a quick look at RFC2822? Mail programs don't respond to the "From" address, they respond to the "Reply-To" address.

I am tending to agreeI just bought a new iBook as well, for the same reasons on the referenced page. I couldn't find a comparable x86 laptop in the same price range, and being a poor college student price was critical.
Since this is my first PPC machine, I chose to take the easy path and install a PPC-only distribution... I chose Yellow Dog 2.0, and I had an easier time installing than Mr. Moffitt indicates. Everything worked "out of the box" for me (pardoning sound, which as he mentions is still forthcoming) except for suspend, which locked up the laptop on resume. A little bit of web research revealed that resuming the new ATI Mobility chipsets was more difficult than some other chipsets, but the problem had been solved in 2.4.x; I snarfed one of BenH's fabulous kernel trees and built 2.4.6. Suspend was fixed, just like that.
Yellow Dog isn't as up-to-date as the distros I'm used to using on x86, but with a little legwork I'm getting it pulled into mid-2001. ;-) The Ximian LinuxPPC 2000 RPMs work fine (although the installer and Red Carpet do not), and a quick rebuild of the jed RPMs got me up and running with a good editor.
I haven't found any documentation on how to turn off the AirPort card when it is not in use (I'm not sure about these 802.11 cards, but I know that regular 802.11 cards suck battery power like its their job; turning the slot off when they're not in use is a big bonus), but the battery life still seems to be 4 hours or so of light usage, less under heavy load.
I don't have the latch problems Mr. Moffitt mentions, either... The magnetic latch thing is SUPER cool in my opinion. It's cool just to mostly close the lid and watch the hook jump out. ;-)
All in all I'm very pleased. Time will tell if my pleasure is well-placed, I guess.

Re:tracking what
I agree that the US money is primativly easy to fake, but there are loads of steps which could be taken without microchips. Without being an expert in printing, I'd say that Australian plastic bills are probably the hardest to fake, as the transparent windows will defeat most methods of copying.

RESOLVE/C++
Nobody has mentioned learning with RESOLVE/C++ yet. I have taken the first 2 classes of this 3-class series at Ohio State, and although I know most of it from AP high school, I think it's a great way to learn programming.. even though many people think it's ridiculous.

power savings by blocking radiationThere's actually a perfectly good reason to block the cell-phone radiation from going into your head, and that is to save power. With current cell phones, about half of the signal is absorbed by your head (hint: water is a very good absorber at microwave frequencies) as useless (but harmless) heat.
(I know of at least one project with Conexant and UCLA directed at using photonic crystals to point cell-phone antenna output away from the head for just this reason.)

Legitimate Patent UsageActually, this is relatively legitimate usage of patent rights. If companies like Magnequench (oi, what a name -- I'm thirsty, anyone want a big glass of magnet?) spent 50 million dollars developing a technology, and everyone else in the world were allowed to simply use it, no one would ever spend any money developing technology, since everyone else in the world can produce it cheaper than them, for not already being $50mil in debt. We might still very well be driving around in horse and buggies to this day, and you can be pretty sure that no computers would exist for the home.
I don't necessarily agree with who they're going after, I seriously doubt that Compaq et al. are manufacturing these magnets in secretive magnet plants hidden deep in the mountainside, in order to avoid the snooping eyes of Magnequench (hahaha, that name doesn't get old), but rather they're just buying magnets from a parts supplier. The reason, however, that Magnequench is going after these big names is simple -- press coverage. I seriously doubt that the equipment manufacturers will have to destroy devices already made, but what would probably happen in stead is that they or their parts suppliers would have to pay damages to Magnebeverage.

Re:"That's where the money is!"
Hey, I remember a similar thing. This girl at school asked me what I wanted to do later in life. I wasn't sure, but I knew it would involve computers (this was around '98-'99). She said something like what people said to you. "Oh, wow, that's a good business to be in. You can make a lot of money." And yes, you can. Computer programmers can get paid a lot of money. Just like, say, car mechanics or engineers. These people make a lot of money, not just because people like to throw money at them, but because they do a job that people want and, these days, need.
I had thought about this response before, so I was a little prepared for it. I replied with something like "Well, yeah, but it's a very volatile market. What if people just decide that they do not need computers any more? They are not a necessity. It might be better to be in, say, the food industry. People will not up and decide that they do not need food."
All in all, I'm aiming to go into a tech-related field (nearing the end of my second year in a university pre-ECE program) because I think it will be fun. Sure I might stand to make a sizeable amount of money, that certainly has kept my attention. But even when I was in 5th grade, I had this feeling that I wanted to do something with electronics*.
In order to keep this post ontopic I'd like to say that I agree with the general point of the story (not that I read it, I can just get the gist of it from the post's title :) ). I've learned a lot by 'playing' with computers. I've wasted a lot of time with them and I think I now have a valuable skill. Hopefully someone else will think so, too, heehee :).
*A little anecdote. On a 'career day'-like thing in 5th grade, other people were dressing up as teachers and doctors and sports players ("I want to be a pro-basketball player!"). I just wore some comfortable clothes ('grubbies', you might say). When we were announcing what we were supposed to be dressed as, I said that I didn't know what I wanted to be but I knew it would deal with electronics. I still find it funny to consider that I knew that and now am aiming to enter a College of Electrical Engineering. Not that it matters to you at all...

Re:Blame the Puritans
Wow, what a simple viewpoint.
First, define "drunkeness". What do you mean? The 13 day moving average of my blood alcohol content? Perhaps you mean the amount of alcohol consumed?
Check out this link and you'll see that beer consumption did go down, but the hard liquor consumption was unaffected.
Check out this link and you'll see that consumption has far exceeded in the years after prohibition any level seen before prohibition. Do you still think we're on the fast track to the level of drunkeness only seen in Russia (ha ha)?
Sorry to interrupt this discussion with some FACTS. I know that sort of behavior is considered rude by some. -

Perhaps consider a CSE program...If you're not completely sure that you wish to pursue one path or the other, don't choose. Do both. Of course, I'm hyping my own school's program, but the Computer Science & Engineering curriculum at Ohio State is broad enough to give you both the science aspect of the CS world as well as the engineering background to be able to apply that science background towards the development of real world things.
Check out their offerings at http//www.cis.ohio-state.edu
I chose the CSE track with a specialization in Information Systems which means that I have the science, engineering, and business backgrounds on my resume, and although this is a LOT of work to accomplish, the applications of that path are very rewarding.
Most of all, do whatever you want to do. At some point, you'll probably change your mind on what you like doing, so also try to make sure that your studies are broad-based enough to give you options to pursue if/when that day comes.

Live Video Solutions
I've done a lot of work in this area. Here's what I think:
Rule 1: don't use real. They have very good audio codecs, but the video stuff isn't worth it because you have to pay for everything.
If you are looking for quality, go with Windows Media. Get a Quad processor beast with an Osprey 500 and serve live MPEG 4. All the software is free if you don't count the operating systam costs.
If you want an Open Source solution use Vic with Darwin Streaming Server I think an Osprey 200 is your best bet for a capture card, but I haven't actually tried this out yet. Note that this uses the H263 codec which isn't much to talk about. If you want to use sorenson codec to stream live to quicktime, well good luck. There's something called LiveIce but it costs 6 grand and it only runs on NT, but you might want to look into that.
Here's some good links to get you going:

Re:This disrupts the voluntary IETF standards proc
