Ask Slashdot: Cross-Platform Internet Telephony?

The Internet | Posted by Cliff on Monday July 10, @08:21AM
from the now-this-would-be-cool dept.
the . Silicon . Dragon writes: "The company I work for is creating a product that we hope to launch on Linux. One of the key features of our product is Internet Telephony where a user can not only call other users on the Internet, but also make and receive calls from standard telephones. We've investigated a number of possible solutions, but they all have shortcomings. The most sour part of the situation is we may have to move our launch platform to Windows if we cannot find an acceptable Internet telephony solution. It'd be highly disagreeable with myself and several others in the company as well if we have to do this, but we can't drop a key product feature and we don't have the time or the resources to develop the technology in-house. Suggestions for Java (preferrably) or C/C++ solutions, and/or references to companies that provide said technology would be extremely helpful." The 'key feature' in question is interface customization. You can find out more in the article.

Intel Tests Show PC133 SDRAM Bests RDRAM

Moreover, Intel has posted those unexpected test results on its Web site, not intending to show PC133 SDRAMs beating the Direct Rambus memory format, which is favored by the Santa Clara chip giant."

Now we can see apples in more movies. Why are all computers in movies apples?

Remember how everybody says the Macintosh has a niche market, and other than that they've got really low market share? Well, guess what that niche market is? That's right - graphics, music, sound, video, film, etc. etc. The people who make movies use Macs.

Of course, it doesn't hurt that Apple often gives computers to movie studios for use in movies. And sometimes they do cobranded marketing, like for Mission: Impossible.

Remember when Forrest Gump bought stock in a fruit company? Apple didn't call the movie studio and ask them to use their logo. The movie studio called Apple and asked for permission.

    There's no way to prevent man-in-the-middle attacks with a truly anonymous protocol as there is no way to verify the authenticity of the server.

    In addition, crypto without a pre-arranged way to mutually verify both parties is trivial to crack. The NSA will certainly not mind you exporting this protocol overseas. :P But that is just a footnote to the above problem I mentioned. You can probably derive the encryption keys by monitoring the beginning of the conversation with the server and thus decrypt the contents of the packet(s). However, I am no expert in this, so I may be incorrect about being able to derive the keys - specifically, I know nothing about the duffie-hellmann(sp?) public key exchange stuff, beyond "it works", so YMMV.

    The other problem I can see is that you're sending up a big red flag saying "Here I am! Look at me, I'm up to no good!" to your network administrators. Net admins are notoriously paranoid, moreso now with the proliferation of scripts. This means that if you use it at work, you stand a good chance of having your network access monitored/revoked and/or you getting your ass canned. Yeah! Go crypto!

    The ideal protocol for this would be one where monitoring would a) do an attacker no good (which means you have to verify the authenticity of the server somehow before you communicate over the unsecured channel (the 'net)) and b) look like normal traffic. This is important - either you encrypt everything, even non-sensitive material, or you encrypt nothing and rely on stenography. I like stenography better myself.. and it'll become more important as governments crack down on conventional crypto - witness new zealand, I believe, which made it a law forcing you to divulge the keys of every encrypted thing on your system under penalty of jail.. even when they can't prove you ever had them!

    Imagine an HTTP request to www.someplace.com where the downloaded JPEG contains the information requested and the POST contents contained the key+query. E-commerce cookies can easily look like crypto keys. Rewrite a few doubleclick cookies and no one will be the wiser.

    Seriously, though, you need to reveal your IP address so the server can send back the information you requested. That's what servers do.

    1) GAC
    by Dungeon Dweller

    I have an active interest in artificial intelligence. I study it as part of my major, and hope to do research in it in the future. As a young man coming up in the world, I am hoping to enter into research eventually, am entering into research at my university (WVU).

    Your project reminds me of several projects/theories that have been discussed before. In the psychological debate, your system depends entirely upon nurture, it would seem. I like that kind of system and research. I do have a few questions.

    1. What separates this from other projects in the field?
    2. Where did you draw your inspiration for this project?
    3. What kind of support staff do you recommend to an individual who has never led research before, but would like to? (I ask this of many of my professors who conduct research)
    4. Where are you getting the bulk of your input for this project?
    5. What do you hope to learn from this project?
    6. At what time will you consider this project a success?
    I know that I posed a lot of questions, but several could be answered in combination, I just didn't want to ask 2 questions at the same time.

    Chris McKinstry:

    Question 1-1:

    There are three primary features of the MindPixel Digital Mind Modeling Project (also known by GAC -- for Generic Artificial Consciousness -- which is public interface to the project) that distinguish it from other large scale knowledge projects such as CYC.

    1. The first phase is a completely public, internet based effort. All the data it will be collecting will come from average people, with no specific training in AI or psychology. It is like seti@home in many respects, except that we're not after your CPU's cycles, but rather your humanness. We're actually seeking to extract the entire content of an average person's mind bit by literal bit from millions of different internet users. We're not trying to write the algorithm for consciousness, but rather create the world's most rigorous fitness test (a Dawkinsian continuous variable) and get it into the hands of researchers who will attempt to make systems that will learn or evolve into consciousness by feeding back against this fitness test. Not only will we be collecting consensus fact, but also consensus emotion. (When the project is fully operational, in addition to collecting information about each MindPixel's truth or falsity, we will also collect emotional data based on Mehrabian's PAD model of emotion.)

    2. The second phase of the project involves releasing the data collected to the scientific community and providing those researchers with some funds (generated by advertising to the people supplying the data) to conduct their research. As a side note, Jeff Elman's page contrains information about recurrent neural networks that are very good at processing just the kind of data that this project will collect and distribute. Specifically his 1990 article, Finding Structure in Time (PDF) is one of the most important neural network papers ever written; it strongly influenced me.

    3. Finally, the project is a meritocracy. People will gain voting rights that will give them a say in every aspect of how the project is run, from data collection and use to the distribution of data and research funds, based entirely on the amount of data they have contributed to the project. The more work you do, the stronger your voice becomes.

    Question 1-2:

    My primary inspiration for the project comes from observation: I observed that computers are stupid and know nothing of human existence. I concluded a very long time ago that either we had to write a "magic" program that was able to go out in the world and learn like a human child, or we just had to sit down and type in ALL the data. When I was studying psychology in the late 80's I wanted to begin to gnaw the bullet and start getting people to type in ALL the data. It was my plan then to get people to enter data as part of an intro psych course, or get the university to allow me ask people for data when they logged on to the university's computer system. I was never able to get permission for either and the idea sat on the shelf until I downloaded my first copy of NCSA's Mosaic in 1994. I saw in following my first hyperlink, a different path.

    I decided to collect my data via the internet. But, the problem was, that I needed to think of a standard format for the data; some way of representing human knowledge that an average person could learn quickly. That idea didn't come to me until I was preparing an entry for the 1995 Loebner Prize. Jackie, my program, was a stimulus response creature. You would ask her a full text question, and she scan her database for a canned full text response. My idea for the Loebner competition was to have her talk to a lot of people a get a lot of canned responses (at the time I was consulting for a large insurance company and brought Jackie to work everyday where she could talk to my colleagues) As well, I stored the responses in a number of different ways: phonetically using soundex, again with all the words in each stimulus sorted alphabetically, and also with a primitive concept token system. So, if there was no direct match, she would look for a phonetic match or sorted or conceptual match. Essentially I was breaking down each stimulus and standardizing it like a Fourier transform breaks down a waveform.

    Then suddenly Hugh Loebner changed the rules. No longer was passing a text based Turing Test good enough for him. Now he would only award his prize if the system passed a full audio/video Inquisition. I hit the roof! Hell, there were tens of thousands of people on the planet that couldn't pass that kind of test! Anyone blind or deaf are just two obvious examples. I withdrew Jackie in a loud protest, stating that intelligence didn't depend on the bandwidth of the communication channel; intelligence could be communicated with one bit! If you locked a person in a box I could detect them with a series of yes/no questions and nothing more. And there all of a sudden, I had my answer (and a quick paper - The Minimum Intelligent Signal Test - An Objective Turing Test in Canadian Artificial Intelligence, issue 41.) There was a minimum intelligent signal, and it was just one bit. I would store my model of the human mind in binary propositions. I would make a digital model of the mind.

    I realized within minutes that a giant database of these propositions could be used to train a neural net to mimic a conscious, thinking, feeling human being! I thought, maybe I'm missing something obvious. So, I emailed Marvin Minsky and asked him if he thought it would be possible to train a neural network into something resembling human using a database of binary propositions. He replied quickly saying "Yes, it is possible, but the training corpus would have to be enormous." The moment I finished reading that email, I knew I would spend the rest of my life building and validating the most enormous corpus I could.

    Question 1-3:

    Support staff! I recommend using the entire planet as support staff! Seriously, don't even dream about it. Almost every researcher I know works on their own or with a handful of collaborators. When you're a big cheese you might get a student or two, but other than that you'll get nothing more than shared use of a departmental secretary. You'll definitely be writing all your own code for a very long time.

    Question 1-4:

    I can't tell you that yet because at the time I wrote this, the project was not yet online (should be now though.) What I can tell you is that in 1995 I did try to collect this same data, using a web based form that sent an email back to me. I managed to collect some 450,000 items. This time, I expect to collect more and higher quality data and I expect it to come from a wide cross section of the internet public. I should also note MindPixels will be collected in multiple languages, which opens up the future prospect of mapping the sampled human languages to each other concept by concept. It will be very interesting to see exactly how an artificial consciousness trained in English differs at the conceptual level from one trained in say, Spanish.

    Question 1-5:

    I hope to learn what the human conceptual network looks like. I hope that in a few years I will be able to access a map of all the concepts in the head of an average person or to have learned why I can't.

    Question 1-6:

    I will consider the project a complete success when the cover of Science announces that for the first time in history there exists an artificial system that has passed a scientifically strong form of the Turing Test known as the Minimum Intelligent Signal Test.

    2) How do you guys do it?
    by pc486

    With exptremely high magnification, how in heck do you keep the telescope still enough to take photos?

    The slightest movement ought to mean millions of miles so thoes pesky little earthquakes should be a problem. Not to mention how you guys move the telescope accurately?

    Chris: You're quite right about the system being very sensitive; if I walk on the azimuth platform of a VLT telescope while we're observing, I will destroy the observation. For normal tracking we use a software system called Tpoint written by a well known telescope genius named Pat Wallace (Pat has a wonderful and detailed article about telescope pointing that anyone seriously interested in telescope pointing should read); the same system is in use on telescopes all over the world. Basically what we do is build a pointing model for each of our telescopes. This involves pointing each telescope to a number of different points uniformly covering the sky. At each sample point, we observe a guide star and record how it moves from the center of the field over about one minute of tracking time. After we have collected enough data, we build a computer model of the telescope's tracking error. Then we basically run the model backwards into the telescope control system and thus apply corrections that try to cancel out the tracking errors of the telescope. This of course can't correct for any unusual vibrations, we rely on normal guide star tracking and hydraulic isolation of the telescope for that. And baring a large earthquake, Tpoint, automatic guide star corrections and the isolation work pretty well (In the event of a large earthquake, there are giant airbags that inflate to protect the mirror from damage.)

    3) How can we help?
    by Mignon

    You probably know about SETI At Home, which lets people volunteer spare CPU time to processing radio-telescope data, in a (so far vain) attempt to find extra-terrestrial intelligence. Is there a similar way that we can help process some of the data that you gather?

    As a simple example, one could compute the differences between a sequence of pictures of the same portion of the sky, looking for anomalies like giant asterioids on their way to wiping us all out.

    Chris: seti@home is one of the most impressive demonstrations of how the world of science has changed. There are now over 2 million average people working together for a common scientific goal. I just wish they sold advertising to raise funds for other worthy (meritocratically determined) projects. It really bugs me that my Pentium III 450 which has done over 7000 hours of seti@home processing since last June, hasn't shown me a single science supporting ad. What a waste!

    Now as for your idea of doing the same thing in optical wavelengths, I think in it there is a great deal of merit. There are a whole pile on new survey telescopes coming online soon that will be useful for just what you proposed. And if you read ahead to my answer to question 11, you'll see I do think it is a problem we have to pay attention to. (As well, I know of at least two virtual telescope projects; the NRC's National Virtual Telescope. See NVO White Paper (PDF) and ESO's ASTROVIRTEL which seek to allow data mining of previously collected telescope data.

    In general, I think the future will see a lot more distributed processing projects doing useful science. The question remains whether or not it is more cost effective to build supercomputers for critical projects or harness the CPU's of private citizens, and I think the answer will need to be determined on a case by case basis. As well, there will be some projects (my own for example) where the CPU cycles are incidental; where what we want to harvest is not your electricity and capital equipment, but actually your humanity.

    4) Division between Science and Spirituality
    by ParticleGirl

    I am continuously frustrated that people's general perception seems to be that science and art, spirituality, and so forth are divided by an uncrossable schism. People feel the need to pit science against spirituality; logic against intuition. It is a rare thing that people accept the idea that these are different ways of approaching the same reality. As a dreamer and artist as well as a respected scientist, what do you say to people who doubt that scientists can be spiritual and artistic people?

    Chris: Science for me at least, is concerned with the external, the measurable; while art is concerned with the internal and immeasurable. Every scientist knows measurement can only go so far; that nature at its most fundamental is immeasurable. Unfortunately many scientists turn away from what they can't measure (and conversely, many artists turn from measurement) instead of finding some way, any way to express it. It is this turning away or fear of the immeasurable (or many artist's converse fear of reduction to measurement) that creates doubt; that separates science from art. The scientist can learn that one does not become any less of a scientist for attempting to express the inexpressible or attempting to measure the immeasurable, just as the artist can learn that because we are neurons and our neurons atoms, doesn't mean we are any less human.

    5) CCD or what?
    by paRcat

    What kind of imaging does a telescope of this scale use? Is it an OWLCCD or something else? What kind of resolution? And how far away would an object need to be before the resolution becomes a shortcoming?

    Chris: I actually can't answer this question. I am only aware of one discussion regarding instrumentation for the OWL and I haven't read it yet. See FROM ISAAC TO GOLIATH, OR BETTER NOT!? INFRARED INSTRUMENTATION CONCEPTS FOR 100M CLASS TELESCOPES (PDF) on the OWL project page.

    6) Yeah, they're big ...
    by viper21

    But what do you do with them?

    What kind of work do the telescopes at your facility generally do? Do local astronomers get to come in and do research or are the scopes reserved for some large project?

    Chris: There is a very wide spectrum of observing programs for the VTL; from the study of comets in our solar system to the detection and measurement of objects on the edge of the observable universe. The VTL operates in two primary modes: visitor and service. In visitor mode, scientists actually travel to Chile and execute their observing program interactively with the support of operations personnel like myself who know the telescope and control system intimately and staff astronomers that know the instruments and science. Visitor mode is best utilized when the program contains interactive components, for example when what the observer does next depends on the results of what he has just completed. In service mode, observers don't travel to Chile but instead submit observing programs that don't have a large interactive component. Service programs are executed by staff astronomers and the data is automatically returned to the observer upon completion. Service mode is much like the old batch mode of mainframe computers. In both service and visitor modes, the programs that get time are determined by an observing program committee made up of scientists from all over the world based on scientific merit. And yes, a portion of the time (I believe it is 10%) automatically goes to Chilean astronomers in exchange for Chile's donation of the land for the project.

    7) How parellelizable?
    by Omnifarious

    How parallelizable is the problem of micro-adjusting small portions of a large deformable mirror to correct for atmospheric distortion?

    I remember a Scientific American article stating that you'd have to devote a top-of-the-line Cray to continuously recalculate the deformations needed given data from the guide star, or laser simulated guide star. If this problem is highly parallelizable, you may be able to get away with _much_ cheaper hardware.

    I'm sure the idea has occured to you, but I want to know what your thoughts are on it.

    Chris: My experience with deformable mirrors is entirely practical and I'm really not qualified to comment on the theory behind them. However, speaking from a practical standpoint, the VLT's 450 force actuators (150 per operating telescope) are each activated about 1000 times per night, night after night almost without error (7 non-critical electronic failures up to May of this year). I see no obvious reason why it shouldn't scale smoothly to 130 or 150 meters with current computer technology. And we certainly don't have any supercomputers doing the deformation calculations.

    8) Why single-mirror?
    by jd

    I could have been mis-reading the article, but it seemed to me as though the idea was to build a single-mirror system. On the other hand, in radio astronomy, and in the insect world, arrays are considered the norm. Is there some advantage that a single mirror gives that cannot be duplicated using multiple smaller mirrors? (Simpler optics is an obvious one, paradoxically. :) Or is this (at least in part) NerdTrek III: The Search for Sponsors, where a record-setting single telescope is going to get more interest than a comparable array?

    (A supplementary question, to go along with this. Let's say, for the sake of argument, that optical arrays are practical. Do you see any possibility of optical astronomers adopting the same line as radio astronomers, in trying to build an effective 1Km+ optical telescope, using an array?)

    Chris: Actually, it isn't a single mirror. It is "filled aperture" telescope. The aperture is filled with many smaller mirrors, just like Keck. And as for optical arrays (interferometers), the VLT (called VLTI in this mode) will be the first real large scale test of such a system. But that stage of the project is still a few years away. In short, we'll have to wait and see how effective it is before we even consider giant optical interferometers.

    9) funding
    by jmayes

    What's the biggest hurdle to hop over in getting funding for projects like OWL? And how did you pull it off?

    Chris: The biggest hurdle for getting funding for projects like OWL, is getting funding for construction! Construction of OWL hasn't been funded, so nothing has really been pulled off, yet. But, if the public really wants projects like this to go ahead, then they need to be active about it. If you're in Europe, write your representatives and mention OWL by name and direct them to the OWL project page. If you're not in Europe, urge your representatives to find some way to participate in this project or projects like it.

    10) Terrestrial Optical Telescopes
    by pb

    What are the benefits of having an Earth-bound, optical telescope? Or rather, what can a larger optical telescope find better from Earth that we can't already find on other wavelengths and from other venues (i.e. The Hubble)?

    If there are no advantages here, is it more cost-effective, or what?

    Chris: What you should actually ask is what advantage does a space based telescope have over a ground based telescope? The only thing you gain from being in space for an optical telescope is better image quality due to lack of atmospheric turbulence. By for every other measure (maintenance, support, materials, etc.) being in space is much, much more expensive and limited. Which is why the Hubble and it's 2.4 meter primary cost a number of times more than the projected cost of of the 100 meter OWL. Recent advances in computer technology (adaptive and active optics) have greatly reduced the advantage that being in space provides at optical wavelengths. For some non-optical telescopes (x-ray, IR, gamma ray) there will always be an advantage to being in orbit.

    11) might as well ask it now..
    by Blue Lang

    I noticed in your 'fave books' section that you have the blind watchmaker, et al.

    so, with an eye towards dawkins' views on evolution, what's your personal take on the probability (not the possibility) of humans locating extraterrestrial life without going outside the solar system?

    Chris: Actually I'm quite pessimistic about the prospects of us locating ETL, AND independently about leaving the solar system. My main reason for this is that I doubt our civilization can last long enough. Not that I think we're going to self-destruct, but rather I think that nature is going to do it for us. It is my opinion that it is much more PROBABLE that we are driven into or close to extinction by an asteroid collision, than it is we will detect ETL or travel outside the solar system. This is one of the major reasons I strongly support construction of self-supporting Lunar and Martian colonies (and sky survey telescopes!) I just don't like us having all our eggs in the one basket called Earth. Having said all that, if we survive, I am confident we will eventually detect ETL, and that we will leave the solar system.

    Question 4: what do you say to people who doubt that scientists can be spiritual and artistic people?

    I would say, go meet some real scientists!!!

    I am an astronomer, and I would say that my colleagues are pretty average Americans in terms of their religious outlook. In fact, some see a very strong connection between their religion and their research: both are searches for the truth.

    I am reading an interesting book called Brother Astronomer, which is the memoirs of a Vatican astronomer (most people don't know that the Catholic church pumps a fair bit of money into astronomical research). Some chapters are rather boring, but others are very enlightening, particularly the chapter about the church and Galileo: the church is actually quite a bit more pro-science than most people allow.

    Science, like spirituality, is an investigation into the nature of the universe. Both are continually evolving as we learn more. For both, what we don't know is much larger than what we do know.

    Voice over IP has been a hot subject for quite a while now, but till now we've never seen it being realised on big scale. First I think it has been marketised too much. Voice over ip is not rocket science. For me, it doesn't say more than 'telnet over ip'. Classic telephony calls are practicaly 100% reliable. TCP/IP connections are too unexpectuous: theres a big risk on delays, that are not important for data, but are so for voice. With TCP, you're sure your packets arrives, but it is too slow for voice packets. UDP hasn't this checking, is fast enough, but you are not sure the packets are delivered. How many times we like to see realaudio clips, but that we can't get a connection. Internet telephony is super for applications like netmeeting etc, but when somebody with a real telephone calls another , he expects that his call arrives, not that it is in a jam. People are used to this. So, in my opinion their will not be evolution to internet telephony as long their is no protocol redesign.

    Actually, with a good compression codec (which are quite common), VoIP can take up less bandwidth than a regular analog call. For instance, with CELP compression it's possible to have a full-duplex communication channel in 9600bps (600Bps * 8b/B * 2directions) + protocol overhead (IP + UDP header lengths anyone?) so on a typical 33600bps connection you could likely squeeze 3 simultaneous conversations. IMHO this is why there was a big push in the wireless telco industry to move to digital (what do they really care about call security?).

    If you think about it, VoIP is more efficient than your "honest" + "proper voice line".

    Honestly, scanning your identity this way is about the last thing you should be worried about. The main goal of testers like these is to be able to scan people rapidly, like the metal detectors at airports. They want to be able to tell if someone is trying to smuggle bombs or drugs onto an airplane. That means that you need to know the answer from your test now, not in an hour or two when the guy's already had a chance to pass his stuff to some third party.

    At the present, and for the forseeable future, it's just not possible to make a DNA-based individual ID in anything like real time. Even in the lab with nearly ideal samples doing that kind of thing takes time, and a lot of that is not something that can be easily reduced; certain chemical and physical reactions take time and can't be sped up. That puts a pretty strong damper on using this as a DNA vacum to violate people's rights.

    OTOH, you can bet that the war against drugs and the war against terrorism will be used as excuses. Pretty soon you won't be able to get on a plane without being subjected to a battery of tests to make sure that you're not trying to put anything illegal onto the plane. Oops, you're a mining engineer who uses explosives at work? Prepare to be hassled every time you try to fly. Your pot smoking brother came over to visit?

    Now, i can't naysay how he sees thing. Currently the money is definitly more likley to come from a company hiring an Open Source programmer who's got a good track record writing free software, but I'm hoping (and betting on) ESR's services-based model. Allison says it breeds non-user firendly code. Hogwash. Only if your company or programming team is unscrupulous or lazy.

    I am hoping that most leading OSS companies like VA and Red Hat don't fit into that particular category. We've all had enough of unscrupulous and lazy software companies. Or at least I have.

    So yeah, Warrick is right about why he got a job, but by saying that's the way it should work, he may be pronouncing self-fulfilling prophesy.

    I hope not. We all have too much to lose if OSS can't make the big leap to big business.

    You know, i'd like to see some hard numbers as to just how many people have actually purchased a Qt License from Troll Tech.. And, more specifically, if that number is sufficiently large enough to really warrant keeping Qt something other than GPL'ed.

    The only thing standing in the way (as I see it) of KDE being the dominant desktop for Linux is this persistant, irritating, annoying, pointless debate over the nature of the Qt libraries. Its a boat anchor that has been dragged behind KDE for far, far too long. Get it over with, guys.

    Its only by pure luck that GNOME development has been centered more on building pointless foo-foo options as of late, rather can concentrating on basic usability issues. Both efforts have boat anchors. One has to do with politics, the other has to do with direction.

    Want KDE to win? Make Qt free. Game over.

    It is encouraging to see a success story about making money in the open source world. I believe that the industry should move towards open source as much as possible, and I completly understand how companies withstand the urge to go open source.

    I have planned on going the same route that the author took in my software developement career. I am planning on doing some development work on some open source projects as an experience and resume builder so that I can fill in the part that talks about experience on my resume. It is a perfect place for new programmers to gain useful experience programming, but I have concerns about a market that is totally open source.

    For all products to be open source is scarey. Now I know that open source doens't necesarily mean free. It means letting everyone know what your software is doing, possibly fixing it for their own use. This type of use is great. But what should a company do if they are making some true innovations. Release that software for the world to look at.

    For example, Oracle may or may not have the most scalable and fastest database. But lets say that their programmers have developed some new methods that enable there database server to be faster and more scalable than the competition. How do the open source gurus claim that opening that software up would help Oracle. This is precisely the part that I have yet to understand. It is the same as patenting a new device. It lets the inventor or inventing company protect there investment for awhile so that even doing the research to begin with is worth it. The patent gives the garantee that the innovation is protected.

    The article didn't help clarify my view of the issues with open source either. There method of dealing with the problem is by having some products open source and free and other products closed source and for sale. This doesn't really answer the question of how to deal with open source software and make money, unless this happens to be the final solution.

    For example, Microsft opens the source to DirectX, IE, etc.. but keeps the source on NT and Office. Of course, this isn't really the core of what they do, it would be like giving out some toys, but not the real thing. Do people think this is the answer to the open source questions, or do people really think everything can go open source?

    Because those weren't available on all platforms when Qt was written (it has always been cross platform, earlier versions had both macro- and template-based containers, for those compilers that didn't support templates back then).

    Besides, QString is UniCode (while std::string is not, since it's just std::basic_string) and reference counted, so you get a performance bonus as well.

    As for bidirectional scripts: there's some support in KDE I think, but as I don't speak any of the involved languages I'm not too sure about it, ask someone. Heck, write to Trolltech and ask them to pay you for writing it!

    A major contributing factor is that developers recklessly chop down trees to make room for suburbs, the scientists said. Trees provide shade from the heat and absorb many of the sun's harmful rays. Without them, the effect is a sort of urban desert.

    I come from a very rural part of Canada--the smallest province in fact, and on Prince Edward Island we have lots of trees, and not much in the way of urban sprawl.

    My first experience in the big city came quite a few years back when I moved to Calgary, Alberta, and in retrospect I feel very lucky. Calgary has an imense amount of greenspace within it's limits--heck we still see deer and get the occasional bear in the 'berbs.

    However, coming from the countryside as I do, I have to say I do miss the trees. If I lived in a larger or more urban city, I'd likley have worse bouts of homesickness :)

    People who grow up in cities often don't see nature the same way I do. Parks are very organized in comparison to raw Canadian wilderness. That said, I'd love to see more green in the urban landscape--and there does seem to be a larger move towards this kind of 'greening of the urban jungle.'

    I remember a report several years back about a high-tech company in Toronto adding an atrium to their front lobby--one that was essentially a giant watershed (read swamp). A fascinating concept--no less than the idea of planting trees and creating parks on the roof's of office buildings.

    I guess what I'm saying is that it's nice to see everyone--urban pesant and country hick living in the big city, see the benefits of greening our cities.

    Maybe one more would be weather moderation. With the thunderstorm raging outside my window right now, that would be a welcome change :)

    The problem with doing this sort of research is the tremendous amount of variables (it's why we can't forecast the weather more than a few days in advance); how exactly it changes seem to differ from region to region. Some industrial cities in Britain show cool islands, presumably from the water released by industrial processes. Cities in western desert areas often have lower temperatures due to increased vegetation and surface water (though the increased humidity often makes it more uncomfortable). If you have access to a good library, Robert Balling is probably the best known researcher working on it today; for fundamentals on urban climate, anything by Helmut Landsberg on the subject would probably be informative.

    The problem is really, what are we going to do about this? A few storms are one thing, but a lot of cities are probably going to be running out of water in a few decades due to the fact that nobody wants to tell people things they don't want to hear; things like maybe the environmental health of a region is more important than having a really nice lawn or golf course, or that just because you've had a constant supply of water for the past 100 years, that it's going to continue. There's a very good reason that only recently have desert areas started attracting real estate development; through most of history they haven't been sustainable. And just because we have better plumbing and air conditioning that didn't exist a hundred years ago doesn't mean the environment has gotten better for us on an environmental level.

    I guess I'm seriously off-topic, but I sometimes obsess with this subject the way some people obsess with the GPL license or open source...

    Cities are a minor effect on the weather when it comes to man made alterations. The weather is "critically dependent on initial conditions" (chaos theory) So, to find the things that man has done you need to look far into the past and find the event with the greatest impact in its time. I believe it is sheep grazing. In Kuwait the US Army has a firing range where no Bedouin shepherds are allowed. The Impact area is verdant and lush. It looks a lot like the great plains (USA) do. Outside of the impact area sheep over graze, ripping vegetation out by the roots, leaving baked dust and sand. This has gone on for thousands of years. Kuwait is very near the Tigris and Euphrates rives, the cradle of civilization. The entire middle east is man (domestic sheep) made desert. About the time god cast man out of Eden he also decided that being a shepherd was better than being a farmer(Cain and Able). I speculate that early man even in Africa domesticated animals and possible even created the Sahara. The loss of Eden was not from god, but man destroying Eden. Cities are recent have a small effect compared to the thousands of years man made deserts have had to work their magic on the environment.

    When I came here from Cali, the first year I was here (1991, fresh outta high school), we had an awe inspiring monsoon season. That was the last good monsoon I remember (though there was one a couple of years later that literally turned the street in front of my employer's office into a river, but a I digress).

    I remember extreme thunder and lightning, and super heavy rains for many days straight (not constant rain, just rain that when it came down, it came down HARD) - the kind of storm where you turn out the lights, go outside, and watch.

    At the time, I was living downtown. There wasn't a whole huge amount of development around the city like there is today. This year, I moved to a house north of the city - out in the more desert area (you know, we have like - coyotes, rabbits, ground squirrels, bats, birds by the ton - and saguaros in the front yard). This season hasn't been any better. Sure, it has been cooler (we are in our monsoon season right now), but it hasn't been rainy. On the days where it seems like it would rain, the clouds appear to part, and go "around" the city.

    I blame it on all of the development - the leveling of desert to put in homes (the house I am in is close to 30 years old - when it was built, the desert was all around it, and the edge of Phoenix was a good 10 miles or more away), getting rid of foliage and scrub, leaving pavement, and a kind of "designed" desert area (where all the saguaroes are "just so" - and things are arranged "just right" - and no cholla allowed, lest someone get hurt!) - none of which helps to prevent what I think of as a "heat bubble" effect - which the clouds drift around.

    Only on days where the cloud buildup has happenned in the previous night do we have any chance of a good rain during the monsoon. Even then, it is only a trickle...

    I want my thunder and lightning back - dammit! (hey, I got UPS's on my system - come and get me!)...

    The built-up area of cities produces 'islands' of higher temperatures, for a number of reasons, among which are:

    Manmade materials like concrete, asphalt, bricks, etc. absorb solar energy much more readily than vegetation.

    Water almost completely runs off because there's so much concrete everywhere, instead of standing around and slowly evaporating. Evaporation can make a significant contribution to cooling.

    Waste heat from vehicles, residences, etc. doesn't help the situation.

    Urban heat islands are pretty well understood. You can get nice images of them--temperature contrasts, that is--from AVHRR (Advanced Very High Resolution Radiometer) remotely-sensed imagery.

    cf. W.B. Myer, "Urban heat island and urban health: Early American perspective", Professional Geographer 43, 1991, p. 38 if yer curious for a little more.

    Throw more heat up into moist summertime air and that's a good prescription for thunderstorms.

    There seems to be lots of evidence in Oklahoma that manmade stuff effects the weather. For example tornados will follow highways. A picture taken on the founding day of Ponca City shows no trees at all. The land was thick grass at the time (the bufflo had not been clearing it for years) but that was cleared to farm. The result was the dustbowl. The solution to that problem was lots of trees. In Kansas now you can see lines of trees along the edge of the farms on the section line roads. Its amazing how well a few trees stop the wind from building up. The large number of man made lakes in Oklahoma have also increased the rainfall in the area.

    As far as dropping something from a plane into a tornado, I don't like the idea of that. The tops of the cloud cells that make tornados in Oklahoma are offten 50,000 ft and have large amounts of windsheer. Flying in a huracane is one thing but a tornado is just too intense. When the F15s get retired nasa may try to adapt one to radio control for just this theory but I think the current plans involve the plane not getting back.

    Intel Tests Show PC133 SDRAM Bests RDRAM

    from the obligatory-note-benchmarks-=/=-real-world dept.
    SteveM wrote citing an Semiconductor Business News article which begins: "SANTA CLARA, Calif. -- Here's a surprise. Benchmark test results from Intel Corp. show its new 815E chip set with PC133 SDRAMs beating the performance of its 820 chip set with Direct Rambus memories. Moreover, Intel has posted those unexpected test results on its Web site, not intending to show PC133 SDRAMs beating the Direct Rambus memory format, which is favored by the Santa Clara chip giant." The results actually show some fairly unspectacular differences, but those differences lean overwhelmingly in favor of the SDRAM. Surely someone will come up with a benchmark that always makes RDRAM look better.

    Tom's Hardware did a moderately detailed benchmark of SDRAM vs. RDRAM a while back.

    Which is better? It depends on both the montherboard configuration and on what you're doing.

    Intel's high-end RDRAM motherboard beat the hell out of SDRAM systems. It had two interleaved RIMM slots, doubling effective bandwidth.

    Intel's more recent SDRAM offerings have generally been pretty bad. Via chipsets put out a good effort, but were still beaten out by the high-end RDRAM systems and the BX board.

    The best SDRAM offering was a 440 BX board overclocked to 133 FSB. Tom swears it's stable. YMMV.

    As far as load is concerned, RDRAM is optimized for throughput, SDRAM is optimized for latency. Something that hits many cache rows in more or less random order taking only a little data from each will work well with SDRAM. Something that processes large amounts of data in more or less linear order will work well with RDRAM. It depends on what you're doing.

    My personal opinion? RDRAM is a bad implementation of a good idea. In five years we might see something better. For now, by DDR SDRAM. YMMV.
