Let's see, perhaps there are other religions that were founded/influenced by other ppl in the last 2K years. And perhaps there are more ppl in the world that are believers of those religions. Muslims, Jews, Buddhists, and Hindi may wonder what is the true meaning of Y2K?
Jesus is just one of many that have had a profound influence on the religions of the world.
I don't say this as total flamebait. Please think about this. If you live in India, China, Japan, Pakistan, to name a few countries, what would your answer be. I don't want you to care about what my religion is, and I don't care to want to know about yours. Whatever it may be, I respect your decision.
Off-topic, but related to VA Linux. I went over to their web site a few minutes ago, and was asked if I wanted a cookie. Okay, that's fine except the cookie would expire on 12/07/99. Kind of strange. Maybe a renegade timed.:-)
Did any of you get an offer to participate in Andover's IPO? They could have offered it up to those with the most/. karma points.:-) I wonder if MEEPT bought Andover stock?
I wonder if my (and another comment) mentioning Andover makes the folks here nervous given the restrictions during the IPO?
Is an IPO the stock market equivalent to a First Post?
You know, there has to been a time when some government 1st authorized wiretaps on telephones. There has to be a time when the physical planting of recording devices was approved. Reading mail, I not sure about this one. Technology advances, and laws naturally adjust. But what remains the same (I hope) are the basic fundamentals that control the rights of the citizens and the role of the government.
The key question is does this new law infringe on the constitution (or whatever they call their basic national laws) of Australia? If it does, then it is wrong and will hopefully be ruled unconstitutional. If it does not, then okay. If the ppl don't like it, then they need to change their constitution.
The same holds true in the US. Remember all the brouhaha over COPA? Ultimately, the high courts started telling Congress that they passed unconstitutional laws.
Some ppl have stated that the gov is doing the same thing as script kiddies. Well, here in the US, law enforcement agencies have been given court approval to break into private property to play listening devices; for instance, this was used in the 80's against New England organized crime. Additionally, wiretapping by the gov is okay if its has court approval. Private wiretapping (like secretly recording telephone conversations) is illegal in many states. Linda Tripp is learning this lesson right now.
The pragmatic purpose of moderation is to allow a reader to filter out useless garbage. As you point out, this was funny. I think that it is absolutely hilarious. I believe that most ppl would also find it amusing. Hence, giving it negative points will deprive others from this very unique and funny post. The other nice thing is that it indicates that Wiechert obviously knows this site. That in itself is Insightful and Informative.
Off-topic? Nah, the interviewee just poked fun at himself. When someone is interviewed, you want to get a sense of his attitude. This showed me that he has a sense of humor.
To me this wasn't elitism in action. It's a great joke; personal self-depreciation. I think that it elitism for the moderators to downgrade this.
What if a Linus interview was posted, or one with RMS? What if they then submitted, "First Post"? That would be ROFL! It would also indicate that they are reading/.
I understand what you are saying about being non-discriminatory, but you sometimes you need to be flexible.
Some ppl have commented about car names. Here's some tidbits from the book, "Eastern Standard Time."
The founder of Toyota is name Toyoda. A fortune teller told him that a name with eight brush strokes (Toyota) would be luckier than one with ten (Toyoda). He was also told that cars with names starting with C would sell better. Camry, Celica, Corolla, Cressida...Tercel?
Nissan (Datsun) was going to sell a car with the name Fairlady. The US division didn't like it so the name was changed to the production code name, 240Z.
Mazda had a van that they didn't import to the US. It would have been extremely popular with a certain group of people. The van's name was, Bongo Friendee.
Nissan came up with the name Leopard J. Ferie, but later changed it to J30.
On a slightly different plane: I always thought that Microsoft was not a particularly "macho" name (if you get my drift).
I enjoyed reading your post. I say this because I am going to nitpick with you some of your points.
The fuse was lit in 1956 when Hungary said screw you. The fuse was lit again in 1968 when the Czechs said screw you. Unfortunately, there was no bomb left attached to the fuse. When Solidarity lit the fuse the bomb was still there. Is the Pope Catholic? Yes, but he is also Polish! Additionally, the breakup of the USSR was starting.
You are correct about Yugoslavia. Ask the average American about the origins and influence of the Ottoman Empire. Ask them about the difference between Roman Catholics and the Orthodox church. Asked them about Sulliman the Great. Like the zones where there are major seismic events, the boundary between Islam and Christians is now the defining boundary. And this line is historical dating back 500 years.
The average American hates each other for many diverse reasons. Other people in this world hate each other for some deep seated, historical reason that is relatively irrational. Choose your poison. All the reasons are irrational.
BTW, I'm American and am trying to learn more about world history.
This far down in the comment chain, but I just want to say that my use of time in my programs use a double is due to several reasons. Part of this is because a need to specify decimal time. I guess that I could use timeval, but I've had some problems due to compiling with the _POSIX_SOURCE flag turned on and off. Additionally, I read something a long time age that time_t might be eventually changed to be a double.
The eventual conversion from 32 to 64 bits is going to create some problems. I have gotten a painful lesson about how one declares variables. Size_t used to be 4 bytes, but in a 64 bit world it becomes 8 bytes. Pointers become 64 bits. Byte alignment becomes a problem unless one anticipate this change. Sizeof(of some typedef struct) changes.
The problem is running a program whereby one tries, fread( &utc, sizeof(time_t), 1, stream_id).
I agree with you. It would appear that many ppl that peruse/. don't know how to intelligently comment on an excellent piece of journalism. The article was extremely bittersweet to read as I was unaware that Lions had passed away. However, the last section about how Lions was so pleased by the publishing of the book was very nice to see. That in itself made the article worthwhile.
As for bickering, how can one attack a story about a great OS, a true educator, and a significant series of events, all told superbly. Furthermore, the author actually married a Linux kernel hacker!
BTW, the book is amazing. How many other times do you get to check out code written by the gods of UNIX?
Good reply. However, SGI does not do a very good job anymore of showing off their good stuff to the general public (perhaps this will changeO. I started off when the demos were shown on a PI. Then it jumped to a Reality Engine. Then it jumped to a....(you fill in the answer).
The original post asked, "what do you show in the magic bus?" You show stuff, but some of the answers that we hear concerning hardware, software, and licences do not make us happy.
In the past, SGI could sell me a fine unix box (well, IRIX had major problems, althouht 6.5 is okay), that was a fine workstation. This is no longer the case. The O2 is nice at it's base price. Tack on the licence fees for the compilers, development licences, NFS, etc... and you get an expensive box.
SGI makes state of the art massive number crunching machinces. SGI make awesome graphic machines. Running performer on my linux box reminds me of this. But ultimately, I feel that SGI survives because of the high-end users.
I like SGI. I hate the cost. If I don't serioiuse number crunching, nor do seriouse 3-D graphics, then why should I go to SGI?
Hmm, haven't seen a web site/.ed for a while. Oh well, somebody's ISP is gonna be pissed.
I hate Y2K. I had to certify a bunch of computers this past year. I hate Y2K. On a more serious note, how do you handle time_t? I stopped using this and changed all my time variables to doubles. Hopefully, I will be retired before the next crisis.:-)
I've used SGI's for 10 yrs starting with a Personal Iris up to an Octane. I also remember when I first saw the Performer demo (driving around the town), flight/dog (that was fun), and other demos. Your point is a good one.
I used to go the SGI Magic Bus and other demos to check out the improvements in the hardware and software (wow, flight has much more texture mapping!) and have been "disappointed" in recent yrs. In the past, the capabilities of the SGI that was reflected in the demos/rendering was truly impressive. However, the current stuff does seem rather dated. Unfortunately, SGI raised expectations too high with their earlier computers.
OTOH, it is difficult for them to truly represent the compute speed of their computers. Additionally, the rest of the industry has made great improvements in both hardware and software.
I must say that I d/l the Linux version of Performer and ran the town demo on a Linux box with dual 400 MHz Celeron CPU's and an antiquated graphics board. It was incredibly slow. I'm going to try another linux box tomorrow, one that has P3's and a good TNT.
Much of what you describe is unfortunately incorrect. I suggest you read Wenz, Acoustic ambient noise in the ocean: spectra and sources, J. Acoust. Soc. Am., vol 34, 1962 (note the year!).
Your flow noise exists for flow around a solid body. Elsewhere, this "noise" would be extremely small. But suppose it did exist. Then what a sensor would pick up would be the noise from sources that were close by; remember, your noise source is omnipresent. Underwater acoustic attenuation is a combination of geometrical spreading and absorption loss. For high frequencies, this loss can be described by spherical spreading with the signal loss related to the distance, R. In this case the loss is R^2. IOW, local noise sources will dominate the signal received by the sensor.
There is something else, this noise source may be incoherent. But in this case, there will be noise cancelation by summing the signal received by the many elements of the receiving array. Result: no noise! But then, how would you hear a quiet zone?
Your last part of your comment describes flow noise past a solid object. In this case, your model is more appropriate for describing noise at the sensor, not the source.
You did get a whole bunch of karma for your comments!:-)
Now I'm convinced that the majority of ppl here at/. don't understand the fundamentals of privacy rights. If you screw up, then you should be punished and severely flamed. No exceptions! Once you start to make exceptions, one starts the stone rolling down the hill.
Problem in the readme file? Sorry, why should I believe that this is the true answer. Perhaps we should demand that the collection of data should be stated in broad big letters. Forget the small print. BTW, how many of you knew that ID was collecting info. This would be a good/. poll.
Should Nazi supporters be allowed to march in your neighborhood (like in Skokie, IL). If it is an expression of free speech, then yes. This is a painful decision to make in support of the 1st Admendent. Should companies be allowed to collect info from you without your knowledge? No, and no exceptions. I must repeat, no exceptions!
Woops, I should have pointed out that from a tactical perspective, one seeks out places where the noise level is high (reduction in the S/N ratio). Variability in the ambient noise level is common. Hence, a drop in the ambient noise level is to be expected. Ambient noise level in the oceans is not a constant.
Your wind model would seem plausible if the wind were a constant source of noise. If natural fluctuation occur, then how do you differentiate betweeen natural fluctuations and the "silence" of a sub?
What are the sources of ambient noise in the oceans? There are several to be considered; rain, biologics, breaking waves, and shipping. These are a combination of low, mid and high frequency sources. I'm going to assume that you are talking about high frequency sources, given that you allude to blockage.
Waves, shipping and rain are sources that originate close the sea surface. This energy needs to be transmitted to the depth of the sub in order for the signal to be blocked. This does happen due to the changes in the vertical sound speed structure in most of the oceans. However, the propagation paths will be complicated due to the vertical sound speed structure and the variablity of this function. Note that rain and breaking wave sources will be broadly distributed (including those close to the sensor).
Biological noise is common in many places, although it is more common in shallower waters. In deeper water, biological noise from marine mammals is observed. For the tooth whales, these signals are high frequency. Certainly, the movement of a vocalizing dolphin that passed behind a sub would be a suspect signal. However, one should not have to depend on this happening.
If you are talking about low frequency signals, then the dominant source is shipping, earthquakes, and whales. However, the longer wavelengths will be more difficult to block.
For something to be more silent than it's surrounding environment means that it absorb energy, block noise from another source, or be surrounded by a sufficient number of noise sources. Without getting into details, this is not the case for the Typhoon.
The Typhoon survives because of several reasons. One it is constructed to withstand punishment. Second, it operates in a friendly environment; under the Arctic icecap or close to protected Russian waters.
Acoustic stealth for subs depends on several factors. For low frequencies that travel a long distance, this achieved by improvements in the sub's props. For high frequencies, this is achieved by isolating internal noise (power plant) from the radiating outer hull.
If you want to play around with 1st principles, consider that underwater sound travels at 1500m/s. At 10 Hz, the wavelength is 150m, while at 1KHz, it is 1.5 m. Consider the receiving array size needs to be several wavelengths long in order to get any directional info. Additionally, most acoustic source need to be about the same magnitude in size as the transmitted signal.
Many ppl here have defended ID as the info collected is relatively harmless. I disagree.
I sometimes deal with civil rights issues and have often been required to use the following type of argument to stop the use of so-called non-PC terms; substitute another offensive term that the person understands. In this case, substitute MS for ID and think about whether or not you would be offended.
Perhaps you may argue that ID is a different company than MS. Yes, you are correct. However, you must apply judgement on an impartial basis without considering the company. In many ways this is the basis of the 1st Admendment.
The transmission of info without the knowledge of the person is wrong. We are going to see this more and more. We must draw the line and say no, this cannot continue. Accepting this type of action only makes other companies view this as accptable.
Another tempest in a teapot. Corel can easily save face and win nex converts if they respond to this "crisis" in a the proper manner. If they made a mistake, the they should say so in a gracious manner. Like Bruce said, mea culpa. If Corel has a legitimate point, but if it is not in keeping with the spirit of the GPL, then they should explain their decision. A stupid mistake would be to hide behind the wall of the legal system. If Corel mainly uses this, then they don't understand, nor appreciate, the open source concept.
If Corel does the right thing, then could come out of this thing like angels. Remember when IBM went after CmdrTaco for trademark violations? After the storm receded, IBM clearly explained their view;/.'s logo was not correct. But here's the correct logo, and/. is clear to use it.
I have to try this out. We have been updating our computer monitors because we had some end of fiscal year money to spend, and it was unanimously decided that newer monitors were a very high priority. BTW, I work for The Man! Of course, we selected monitors that we thought were a good combo of quality/price. Needless to say, our purchasing office initially questioned our decision because they could buy cheaper monitors. We could only justify our decision by writing up some plausible reason.
Now I can just say that these monitors are ergonomic. In fact, I can now buy even better monitors (assuming we have the money). And if someone complains, we might have to get even better monitors. The next thing will be that we have to get LCD flat panel displays as CRT are too heavy to move around.
BTW, we got Viewsonic PS790's as we liked the overall quality, price, and short-neck design. Please, no flame wars about what monitor you like.
Your points are well taken. However, do you foresee a day when there will be no floppy disk? Support and need for legacy devices is a touchy subject. But nothing pushes forth improvement as the cutting off of old legacy devices. Apple did this and the eventual result is the appreciation/support of USB devices. Linux support for USB needs to be improved. How long will the serial port be around?
Their was a time when 9 track tapes ruled the world. A lot of these tapes still abound. But obviously this technology is obsolete. So is the floppy.
The best way to maintain job security is to have legacy code written in an out-dated programming language. And as far as obscure coding goes, what is better than writing in a language that is no longer taught to the kiddies that may take your job away.
You may laugh at this. I don't. We have a Fortran programmer that wrote a lot of legacy production code (for the Vax). I know fortran (at least up to fortran77) although I haven't written in this language for a long time. Some of the younger ppl trying to port the code to newer systems have had a miserable time. But, hey, no problem! This guy is going to port his code to run on a unix system and will rewrite in C. No wait, he decides that he will skip c and rewrite the code in a new language that he hears is all the rage; c++. Two years go by.
He gives up learning c++ and ports his code to c. Another two years go by. If you know fortran, then you know that character manipulation is a bitch. I check his code and realize that he does not know the rudimentary aspect of c. He has essentially rewritten the function atoi. yikes.
On a side note: Obscure variable names is nothing new. Take a look at old fortran code written for a system with a 8 character limit.
On another side note: Many, many moons ago in my 1st computer class (fortran), I wrote a program that used the variable names kitty, cat, meow, and woof. Kitty was the integer equivalent to cat, and meow was the integer equivalent to woof. The prof was not pleased despite my explanation of the brilliance of my choice of variable names.:)
I'll state many things without explanation, which opens me up for questions.
Wait for the POP mobos.
The ppl working to get linux running on the PPC are incredible. A relatively small cadre of ppl have done an outstanding job. And no, I won't kiss you.
Apple zealots have many simularities to Linux zealots. They both passionately believe in their OS and platform in a sense of loyalty that is beyond the normal realm of normality. Why do they have this similar passion? Could it be the Devil?
MicroCenter this past weekend has clearly shown the true path for Apple.
Back on subject. USB on linux is a priority for Mac users. It was not a priority for linux before then. The floppy disk as we know is going to be gone eventually. Do you have a 5.25" disk drive on your computer? Hmmm, that was available a few years ago.
I'm going to make the big assumption that this chip is geared for mobile computing devices. Then there are several key factors. Power consumption is obviously extremely important. To cut down on power, one needs to reduce the instruction set and associated circuitry to it's bare minimum. In a rather simplistic way of thinking, this imposes greater burden on the OS to efficiently handle the computations. Yes, Linus is concerned with power consumption on his laptop, but is he more power consumption concieous now?
But what OS? One one hand, one has to consider a Linux variant because Linus works there. Hmmm, RedHat purchased Cygnus who has expertise in...? This would raise colusion concerns (nah, why should it). Linus has also said that he wants better power management with linux. No surprise there, just look at what Apple has been working on with OS with regard to the iBook and PowerBooks. And to those that wonder about X Window, yea what about it? Linus may remember a time when Linux was not totally tied into X.
OTOH, Paul Allen is a serious investor in Transmeta and would not benefit from a diminishing of his stock valuation in MS. OTOH, Allen marches to a beat of a different drummer. Also consider what else Allen has been investing in.
Okay, speculation. Scaled down cpu with a scaled down OS that doesn't cause one to wince. If they do it right, it will be a scaled down merging of an OS with a CPU.
Flat panel screens are amazing. Keep in mind that there is a difference between analog and digital screens. Digital screens are amazing when you 1st see them, but commonly have a fixed ideal resolution, and are too sharp (?) when they are viewed for a long period of time. OTOH, analog screens are more familiar but may be "fuzzy".
As for laptops and notebook computers, the current pragmatic issue is size, weight, and power consumption. Obviously, you do not want to lug around a heavy piece of fragile equipment, nor want a power sucking hog when one is truly mobile. And the best thing since slice bread are laptops with DVD drives and decoding. If you travel, there is nothing better than to pop in a movie when your flight has been delayed/cancelled, while your fellow travellers bitch and moan. One thing that I learned is that one should travel with at least one good PG or PG-13 movie as you don't know who you will sitting next to on your flight. I learned this while watching Aliens while sitting in an aisle seat. woops:-)
Now I will admit that I'm a mac-addict. I have a lombard powerbook (dual boot, macos and linuxppc). Some ppl that I work with just got a IBM 570 notebooks but realize that there is no composite S-Video output. Some with Dell laptops realize that their batteries don't last that long.

Now I can just say that these monitors are ergonomic. In fact, I can now buy even better monitors (assuming we have the money). And if someone complains, we might have to get even better monitors. The next thing will be that we have to get LCD flat panel displays as CRT are too heavy to move around.
BTW, we got Viewsonic PS790's as we liked the overall quality, price, and short-neck design. Please, no flame wars about what monitor you like.
Their was a time when 9 track tapes ruled the world. A lot of these tapes still abound. But obviously this technology is obsolete. So is the floppy.
You may laugh at this. I don't. We have a Fortran programmer that wrote a lot of legacy production code (for the Vax). I know fortran (at least up to fortran77) although I haven't written in this language for a long time. Some of the younger ppl trying to port the code to newer systems have had a miserable time. But, hey, no problem! This guy is going to port his code to run on a unix system and will rewrite in C. No wait, he decides that he will skip c and rewrite the code in a new language that he hears is all the rage; c++. Two years go by.
He gives up learning c++ and ports his code to c. Another two years go by. If you know fortran, then you know that character manipulation is a bitch. I check his code and realize that he does not know the rudimentary aspect of c. He has essentially rewritten the function atoi. yikes.
On a side note: Obscure variable names is nothing new. Take a look at old fortran code written for a system with a 8 character limit.
On another side note: Many, many moons ago in my 1st computer class (fortran), I wrote a program that used the variable names kitty, cat, meow, and woof. Kitty was the integer equivalent to cat, and meow was the integer equivalent to woof. The prof was not pleased despite my explanation of the brilliance of my choice of variable names.:)
Wait for the POP mobos.
The ppl working to get linux running on the PPC are incredible. A relatively small cadre of ppl have done an outstanding job. And no, I won't kiss you.
Apple zealots have many simularities to Linux zealots. They both passionately believe in their OS and platform in a sense of loyalty that is beyond the normal realm of normality. Why do they have this similar passion? Could it be the Devil?
MicroCenter this past weekend has clearly shown the true path for Apple.
Back on subject. USB on linux is a priority for Mac users. It was not a priority for linux before then. The floppy disk as we know is going to be gone eventually. Do you have a 5.25" disk drive on your computer? Hmmm, that was available a few years ago.
We need universal firewire support.
But what OS? One one hand, one has to consider a Linux variant because Linus works there. Hmmm, RedHat purchased Cygnus who has expertise in...? This would raise colusion concerns (nah, why should it). Linus has also said that he wants better power management with linux. No surprise there, just look at what Apple has been working on with OS with regard to the iBook and PowerBooks. And to those that wonder about X Window, yea what about it? Linus may remember a time when Linux was not totally tied into X.
OTOH, Paul Allen is a serious investor in Transmeta and would not benefit from a diminishing of his stock valuation in MS. OTOH, Allen marches to a beat of a different drummer. Also consider what else Allen has been investing in.
Okay, speculation. Scaled down cpu with a scaled down OS that doesn't cause one to wince. If they do it right, it will be a scaled down merging of an OS with a CPU.
As for laptops and notebook computers, the current pragmatic issue is size, weight, and power consumption. Obviously, you do not want to lug around a heavy piece of fragile equipment, nor want a power sucking hog when one is truly mobile. And the best thing since slice bread are laptops with DVD drives and decoding. If you travel, there is nothing better than to pop in a movie when your flight has been delayed/cancelled, while your fellow travellers bitch and moan. One thing that I learned is that one should travel with at least one good PG or PG-13 movie as you don't know who you will sitting next to on your flight. I learned this while watching Aliens while sitting in an aisle seat. woops:-)
Now I will admit that I'm a mac-addict. I have a lombard powerbook (dual boot, macos and linuxppc). Some ppl that I work with just got a IBM 570 notebooks but realize that there is no composite S-Video output. Some with Dell laptops realize that their batteries don't last that long.
Subject says it all.
