  1. Re:I've heard this before. on Mandelbrot Suggests A Hunt For Financial Patterns · · Score: 1
    I once spoke with a trader at a major Wall Street firm who believed that prices have "supports" and "restraints" -- i.e. natural floors and ceilings that they don't want to break through. When I asked her what happens if a price breaks through the floor, she responded with the hilariously tautological, "well, it just goes lower until it establishes a new floor!"

    There is actually some truth to that. Don't forget traders are human beings, and humans tend to favor certain numbers. As a very simple example, people tend to instinctively buy and sell at 1.10 1.15 1.20 and avoid 1.16 and so forth. Of course most traders are aware of this, so it gets pretty complex. Anyway, the point is that if a lot of traders are prepared to buy at certain price, the price won't drop easily below that.

    Another thing to take into account - one reason why technical analysis "sort of works" is that so many people look at the same patterns. Which is kind of silly if you think about it.

  2. Re:Too much tech in cars already on Remote-controlled Bolts and Screws · · Score: 2, Insightful

    There's already way too much tech in our cars already. I love technology, but there are some places where it should be kept to a minimum. I long for the days when you could work on your own car with a decent socket set and a few wrenches.

    Well, you still can do a lot. The engines aren't that different. Granted, software problems can be a PITA, but I think people are generally more scared of them than they should. I think intelligent fasteners sound like a good idea; encryption and encoded serial numbers would make selling stolen cars and car parts a nightmare.

  3. Re:46% of music sold? on EC Approves Unconditionally Sony-BMG Merger · · Score: 1

    That is a scary statistic. Even more so if you're a musician.

    It shouldn't be. There are more indie labels at the moment than there ever was before, and I think a part of the reason for the high % is the fact that in addition to their own releases, Sony also distributes a lot of indie stuff. As an example, the band of a friend of mine recorded for a small indie label, but their album is distributed by Sony Music in Europe.

    Well, did you check the Looking Glass video? I really think this could be what eventually kills Windows. I can't wait to see people looking over my shoulder and saying "Wow - where can I get that?". Because I sure as hell am sold.

  5. Re:NULL is a nuisance on SQL, XML, and the Relational Database Model · · Score: 1

    It's a not defined value (comparable with a division by zero). One of the consequences (for example) is that you can't join on NULL columns. Theoretically you can't even sort (ORDER BY) on null values.

    COALESCE(col,0) or something similar works most of the time. If a col is null, it most often also works correctly in queries - the rows that have a null value are simply left out. Logical and for the most part efficient.

    In your example to replace the NULL by an impossible death date (i.e. 31-Dec-9999) and let the application deal with it.

    That's a kludge that sort of works. But it is almost guaranteed to cause problems at some stage. And you could always just say SELECT foo FROM bar WHERE mycol IS [NOT] NULL.

    First, why do researchers assume that blood flow and glucose use equals proof of thought patterns? Now, there may be a correlation, but as my research methods professor loved to say "correlation does not equal causation"

    Doesn't correlation by definition mean that something is only seemingly related? The term would not be used if the cause-effect relationship was known. I don't think anyone in their right mind reads these studies as the ultimate truth. It's just interesting phenomena that can't be explained with chance alone.

  8. Re:Black? on Sony Projector Gets Bright Images From Black Screen · · Score: 3, Interesting

    It seems this is a surface that reflects only very selective frequencies, those used by their emitters. An interesting idea, but calling it black is deceptive.

    If it looks black to the naked eye, isn't it then... black?

    I wonder if it works with any projector, or just some specific kind. I always liked the picture quality of LCD projectors, but the fact that they require a very dark room to get any kind of reasonable contrast has kept me from buying one. Now this might change that.

  11. Re:HA! on Australian Record Industry Has Best Year Ever · · Score: 1
    Yeah, whatever happened to that company that used a file-sharing program to determine what was the new-hotness, and was willing to sell cutting-edge marketing info to record companies, based on actual interest of the target audience?

    I don't think it works that way. People download what's already well-known (i.e. what's currently on the charts etc). I have a hard time imagining someone typing in random keywords just to check out new music. I suppose accidents DO happen, but mostly people just want their Britney Spears fix. The big paradox in all of this is that an artist actually needs record sales in order to generate p2p downloads! I don't know what it amounts to and I doubt if anyone does...

  12. Another Real World Observation on SCSI vs. IDE In The Real World · · Score: 1

    For what it's worth, I am the chief recording engineer of a professional recording studio. All our multitrack recording goes to hard drives these days. DSP and streaming 80 tracks of 192 kHz 24-bit data are both I/O and CPU intensive - continuosly reading data from all over the disks and processing it.

    Now, what I've noticed in a lot of SCSI vs. IDE speed tests is that most ignore two very important things: CPU consumption and continuity of throughput, both very important for our purposes. I've done a lot of comparisons of my own, and unlike the reviewer, I've actually always used the same exact drive in both SCSI and IDE versions when testing. The conclusion? SCSI sweeps the floor with IDE. IDE requires a lot more CPU (all pro audio apps have CPU and disk throughput meters so this can be measured easily) and there are many more problems with them in general.

    For example, I've witnessed cases of an IDE drive introducing crackles and pops in the audio (as if it's not keeping up with the data stream) when a SCSI drive with the exact same specs from the same manufacturer works perfectly. Let alone the ease of setting up SCSI RAID arrays etc.

    This may not be very important to a home user, but to me it seems there is never enough power in any computer or mass storage device.

  13. Prior art...? on Online Auctions Patented, eBay Sued · · Score: 5, Informative

    University of Turku has had an online aucion server for 10 years or so. They used to e.g. auction all their old computer gear, instead of throwing them away. It was pretty popular, although I think they have taken the service offline now.

  15. Wondering again on Attack Of The Dreamcasts · · Score: 2, Insightful

    Almost all companies I have visited have had the opposite 'problem'. To get an Internet connection up n' running, you need to phone a sysadmin to patch the ethernet socket to the switch (most often, the spares aren't connected at all) and then give them a MAC address so the dhcp will give the box a legitimate IP address in the correct space. (Also, Dreamcast?? Suspicious, no?!)

  16. Re:High Frequencies on Using Your Computer to Repel Pests · · Score: 3, Informative

    Mosquitos have no such hearing capacity

    A simple Google search found this at Earthlife.net: Sound is very important to mosquitos for a number of reasons one of these is the location of mates. The antennae of male mosquitoes are sensitive to the sounds created by the beating wings of females of the same species. Because females are usually larger than the males, the wings of males and females beat at different frequencies. This makes it possible for males to distinguish females from males based on the sound of the beating wings and helps in the detection of females of the right species

    So they do hear high sounds (and probably very faint sounds, too), though there is no mention of them actually recognizing their enemies from sound. There are lots of those electronic gadgets available, though.

  17. High Frequencies on Using Your Computer to Repel Pests · · Score: 2, Interesting

    The electronic mosquito repellents use ultrasonic sound, i.e. sound that is so high that it can't be heard by humans. Basically, they emit similar sounds as the natural enemies of mosquitos. I really wonder how well such sounds can be reproduced using regular computer speakers that can barely reproduce the frequencies we hear.

  18. It's Really A Good Thing on Smart Mobs, Swarms, and Flash Crowds · · Score: 2, Interesting

    I like cell phones, SMS, PDA's whatnot. I like the fact that I can be reached and I can reach my friends most of the time, and I like a calendar that beeps an hour before an important meeting etc. I think currently we are seeing a lot of people overusing their newly discovered communication media which has spawned the inevitable anti-cell phone movement. Eventually, however, I am sure what will happen is what has happened with every other new technology, i.e. these tools will become part of our everyday lives and the novelty will wear off. People will get used to all their toys and will discard the features they don't need. Not every celebrity sighting will be SMS'd to everyone at that point anymore. I think it is not a coincidence that only the 'social' side of the mobile technology has really caught on. People want to talk to other people, either via SMS 'chatting' or regular calls, download ring tones (so their *friends* will hear them when the phone rings!). The faceless 'mobile Internet' seems to Interest very few people. Contrary to many people, I also tend to think that the fact that people have the guts to talk about their private lives in public is a good thing. It's almost like free counceling. Of course, there is a limit to what I want to hear... - FF
