  2. Re:Well.. doesn't the dictionary make it smaller?? on Compress Wikipedia and Win AI Prize · · Score: 1

    The contest requirements add the length of the decompressor program to the size of the compressed file; therefore a dynamic dictionary you build yourself (and store in the file) will be better than using those generic ones. From the faq:

    The typical size of current decompressors is less than 100KB. So obscuring them by making them shorter will give you at most an 0.1% = 100KB/100MB advantage (not enough to be eligible for the prize). On the other hand, for fairness it is necessary to include the size of the decompressor. Take a compressor like PAQ8H that contains 800KB of tokens. Clearly it can achieve better compression than one from scratch. If you're not convinced by this argument, consider a an extreme "decompressor" of size 100MB that simply outputs enwik8 byte by byte (from a zero 0 byte archive), thus achieving a compressed size of 0.

  3. RedHat as a stable platform on Ubuntu to Bring About Red Hat's Demise? · · Score: 1

    There are already plenty of free Linux distributions that work OK. RedHat has two things going for it that keep everyone I know with licenses buying them.

    The web-based management tools that are available as part of the RedHat network are pretty good. You can inventory all your machines, see who hasn't been keeping their systems patched (and push updates to them if you want), find out exactly what hardware is in the system, all sorts of useful things right from the admin web interface. I've even used it to lookup the Dell service tag for a system. One place I worked with found it worth buying the RedHat subscription just because of how much these features reduced their Linux TCO by letting administrators manage more machines efficiently.

    The second thing is the more important one. RedHat puts a lot of work into keeping their Enterprise products stable for a long time period. That's one of the reasons so many application vendors have standardized on them: they don't have to worry about totally uncontrolled package upgrades.

    An example will illustrate what I'm talking about here. Some months ago, I was doing work on a RHEL machine that involved installing some PHP software. When reading through the requirements, I discovered there was a security exploit in the version of PHP installed on that system (php-4.3.9), and got a bit paranoid about it. Upon checking further, I discovered that RedHat had backported the security fixes into the older version of PHP they ship with the system, and the exploit I was concerned about was in fact closed. Most vendors in this situation would have just upgraded everyone to php-4.3.10 because backporting takes considerable resources to do, leaving the customers exposed to whatever functional differences there are between 4.3.9 and 4.3.10.

    It's fine for my PCs, but when I'm in a situation where I'm supporting lots of machines, the thought of users being to get a whole new set of packages with who knows what changes just by running some variant on apt-get gives me the willies. RedHat's pace is just fast enough to stay useful in a corporate environment, while going out of their way not to upgrade any more than is necessary. I'm curious how the Ubuntu server plays out in this situation; the desktop version is clearly far too quick in its pace of upgrades for any of the RedHat customers I deal with to be comfortable with it.

  7. Re:Catastrophic Failure of Flash Memory on The Benefits of Hybrid Drives · · Score: 1

    You're describing this disaster scenario as if it's a new problem introduced by this technology. I've already had plenty of demos I was doing for important people blow up because of a hard drive error (I'm just lucky that way). Which is more likely: that you'll hit the flash write limit, or that the mechnical part of the drive will crash and burn? My experience with hard drives suggests they're none too reliable right now, and anything that can reduce the amount of time they spend moving around has a potential to improve the mechanical failure rate.

    With wear leveling and some spare capacity to replace early bad bits, 100,000 write cycles for each bit works out to quite a bit of data with a decent size chunk of flash. An analysis I liked at http://www.sudhian.com/index.php?/articles/show/68 6/3 suggests a typical office worker will get 33 years out of a hybrid drive, while even someone who writes 6GB of data every day should get 4 years out of the drive. There are plenty of drives out there that aren't even warrantied for 3 years right now.

    As for too much writing induced disasters, you just have the flash part of the drive start throwing SMART errors when it gets low on useful bits, the same way drives right now can report when they're running out of spare sectors to relocate bad drive sections into. That should catch the issue well in advance of a flash crash.

    When you run the numbers it doesn't sound that difficult to create a flash-based design that would likely outlast the mechanical parts of a standard hard drive.

  10. Re:My Advice on Investing Tips for College Students? · · Score: 4, Informative

    I wanted to add some confirmation and some slight different suggestions to this excellent set of advice.

    I've also dealt with ING Direct for a number years (and in real US dollars even!) and they were the first thing that came to my mind as well for the situation asked about here. You can move money in and out of the account as fast as your bank will clear the transactions, making it fine for use as backup cash, and the interest rates soundly thrash most other savings vehicles.

    Comments about clearing debt and such before investing are spot on, but I think the timeline outlined here is a little conversative. It's not that hard to extract money from the stock market when it's in a liquid stock like SPY, where you don't lose much in the buy/sell spread to enter and exit the transaction. If you needed emergency money, you can get it out of a good brokerage account in a few days by closing your position and wiring/ACH'ing the proceeds out. As such, waiting until you have lots of money on top of a large safety net may not be necessary for those willing to tolerate some additional risk. If your debts are paid off, you have a full term worth of cash, and another $3K on top of that, putting that $3K into a relatively safe stock market investment instead of a savings account would be aggressive, but not crazy. Stashing 2-4 terms worth of money probably makes sense to a really long-term student like our poster here, students doing a shorter tour of duty will have graduated before they meet that standard.

    That said, I'm a little torn on the subject of investing in ETFs like SPY right now though. If this were early 2003, where the stock market was fairly priced by historical standards, then I'd say jump on that. But the current S&P is showing a lot of the signs of a peaked market right now; it's been going straight up for over three years, it's already recaptured most of the lost ground from the .com bubble bursting, and there have been some sell-offs on massive volume this summer. There's certainly some room for it to keep going, but I'd hesitate to recommend that as a passive investment vehicle at the moment--there are a lot of signs the best part of the move is now history. You don't want to be one of those people who buys into the stock market just as it hits its peak, only to watch your money get chipped away for years by a bear market.

    It's also worth noting that while Graham's "Intelligent Investor" is a great book, it's hard to follow some of its principles while trading ETFs. Compared to the relatively easy way you can characterize the intrinsic value of a regular stock, it's not as clear what the intrinsic value of a an ETF like SPY is.

We'd gotten in some samples of DVDs where the manufacturer was touting the high video production quality of the product, all the way to using a higher than average bit-rate when encoding; none of this soft focus stuff. My boss wanted to know whether there was a big enough difference there that it would make for a good demo (the real money in hotel video on demand is all in the porn). As a single guy who had a 65" HD-capable Toshiba rear-projection CRT setup at home, I was the obvious flunky to check that out. I watched for a bit that night and brought the DVDs back the next morning, frown on my face. When asked "what's the problem?", I said "two words: razor bumps. I don't need to see that much detail."

    Fast forward to last year. My sister had a nice HD LCD TV, so she jumped at the chance to get her cable upgraded with Comcast's HD box ("The Sopranos" in HD was the big draw). Late one night I stopped by, wired up the component video, sorted out the surround sound issues, and went browsing around the channels for good HD content to show the result off. After going through a few channels of "HD" that was obviously just upsampled junk, I found an unexpected source for some great quality video obviously shot in real high-def: HBO's "Cathouse", a documentary series about the goings on at a Vegas brothel.

  19. Re:They put a lot of stress on your knees. on Do Ergonomic Chairs Really Work? · · Score: 4, Informative

    Years of leg-heavy sports and weight lifting had made my knees very strong. So when I found myself having posture trouble when working on my computer too much, I switched to one of these kneeling chairs and never had any problems with knee pain.

    That lasted about a year. The position you're put in with a kneeling chair shifts a lot of the weight your back would normally bear onto your hips. One day I found that my hips hurt when I walked; it was obviously getting much worse when I was kneeling in the chair so I stopped doing that. It was too late to reverse the damage by then. It's been 18 months since, and I still haven't completely recovered use of my hips.

    If your posture is bad, and your back is bothering you, you can play with chairs all day; all you'll do is shift where you're putting the pressure at to some other part which will then buckle eventually. You need exercise that targets that specific weak area to correct this. Archery is better than nothing, I guess, but I wouldn't expect that just focusing on posture alone would give great results. You need to force your muscles to bear weight beyond their normal range to get them to grow, and my recollection of archery mechanics recalls it only really works the upper back muscles.

    Since my case was bad by the time I had the resources to address it, the only thing I found that worked was combining ideas from my doctor, a physical therapist, and a personal trainer until I had a back workout routine that really made me feel where the back muscles that bear weight were at. Once you achive that, you can practice flexing them and train them properly to support more of your weight. I can now sit up perfectly straight just by tightening that part of my back and all sorts of problems have gone away. I find myself arching my back over the top of crappy chairs when I have to sit in them, not even using the back of the chair if it's not the right shape.

    Check out the fun list of exercises at http://www.thetrainingstationinc.com/back-exercise s.html

    It's the lower-back section that mirrors what I ended up doing. My doctor recommended against Hyper-Extensions as being too stressful, and my hip issues made Deadlifts difficult. The Lower Back Machine exercise has worked wonders for me (in my gym as the Icarian "Low Back Extension" machine), and I'm hoping to introduce the Good Morning exercise in the near future.

Russia is still working out some issues there.

I think that stretching laws aimed at people bringing stuff back in a suitcase or shipping through the mail into downloads is just that, a stretch; I find the moral position very clear even if the legal one isn't. This will work its way out in the courts eventually, both here and in Russia. If instead you went to one of the Asian countries where DVD bootlegging is rampant because of weak copyright enforcement, bought some movie on the street, and brought the disc back in your suitcase, you'd probably get away with that too.

    The position of the Russian ROMS system that collects royalties seems to be that their members can sell just about any music they want, and it's the copyright holder's job to make sure they collect their fair share of the royalties for it. Clearly this is backwards; they shouldn't sell anything until they've obtained those rights first. If they were properly licensing music so that US artists were compensated properly for it, that money would be returning to the US via organizatios like the IFPI. Their press release at http://www.pro-music.org/musiconline/news060602a.h tm says that's not happening, and summarizes things nicely with:

    "The site claims to have a licence from ROMS, a Russian organisation that claims to be a collecting society. Yet ROMS has no rights from the record companies whatsoever to licence these pieces of music. ROMS and allofmp3.com are well aware that record companies have not granted authorisation for this service."

    If you look at the Museekster link above, I think the Beatles/Metallica situation highlights best the problems with allofmp3. From that site: "under Russian law a collecting society like ROMS automatically has the right to license ANY intellectual property to Russian distributors, even if the author is not subject to Russian law." This is a good summary of what I've read in several places, and this situation is obviously nonsense. If I own the copyright on something, you can't just decide that it's OK to distribute it. Tell me how those two artists can possibly be compensated for their work properly when it's their position that no one in the entire world is even allowed to sell their works on-line. The only legal way to own the Beatles or Metallica music is to purchase their CDs (or LPs, 8-tracks, etc.), period. If you don't like that, don't listen to them. It obviously follows from this fact that anyone distributing those artist's music via other means is a criminal, no matter what lame "it's legal here!" nonsense they spew.

    If you're already aware of all this, and consider yourself clean anyway, well good for you. I occasionally socialize with people who worked on Beatles albums and I like feeling comfortable when I talk to them. I don't pick their pockets when I see them, and I'm not real fond of thieves who do.
