  1. Re:Price too high? on Lights On But No One Home At Sun Grid · · Score: 1

    There was a lot of debate the last several times this was posted about Sun's $1/cpu-hour price, how TCO is a lot more than hardware cost, etc. Still, a google search reveals a bunch of other companies who lease out CPU farms (mainly intended for rendering), who charge less than $1/cpu-hour.

    You've also got to consider that Suns are slow, so its even more expensive. I'm not just saying this, I've run tests on everything from an UltraSparc2 @ 333Mhz to an UltraSPARC3 @ 1.2GHz. They are particularly slow in memory bandwidth. They are not as well supported with 3rd party hardware (eg, interconnects) or software as Linux is. Also, their newer processors do not come with as much onboard cache as they used to. I've seen some programs run faster on our slowest machines because of cache coherency. This is a little different now that Sun has gotten on the AMD bandwagon, but those are pretty much commodity that can come from anywhere, and all in all Linux is generally better than Solaris at HPC kind of applications. Solaris is a better operating system in terms of maturity and whatnot, but I and most others agree that Linux is a better choice.

    I was half joking, half speaking in the theory behind the second amendment. And with every incident where someone brandishes a gun, the likelihood that they will die goes up immensely, especially when involving other armed people that are trained to kill.

    Oh, and dying is much more preferable to going to Guantanamo, even though they are almost the same. However, in Guantanamo, there is no paper trail or legal representation, you're more than dead there.

    However, the government gets taken aback when confronted, even if it ends in death. Neither Ruby Ridge nor Waco will happen again. Never. And that was entirely because people were willing to die for their beliefs.

    Something does need to change. It seems that it has become too easy for politicians to give away our rights in the name of fighting terrorism.

    Yeah! Lets write a letter to our congressman. Or at the least be sure to get out and vote for the "right guy". Or donate to the EFF.

    Or were you thinking more along the lines of coup d'état or something?

    Its a shame that our excellent constitution, the longest standing one in the world, will outlive the government and the country that it is supposed to frame. Yes, there are newer political parties that have names like "Constitution Party" and "Libertarian Party", but they get almost no popular support.

    I'm not saying this to be the almighty doom and gloom guy or because it empowers me in some way, but if something does not fundamentally change with the people in the United States in the next 100 years, then they can and will have many changes imposed upon them.

    Historically, dominant societies do not last longer than 200-400 years. So much of our economy and well being is dependent on our country's population growing. We are the only industrialized country that has a significant population growth. We talk lip service, and annoy our own citizens in order to fight the new "war on terror", yet let if not even encourage _millions_ of Mexicans to illegally enter our country every year. Its a good thing that none of the Mexicans are terrorists or terrorist-like and that the real terrorists have never heard of the country either. This growth helps mask our deficit spending, but neither can last.

    Americans should focus on stepping down as the world leader and policeman, and becoming more like the established countries in Europe or similar. Yes, those people live much differently than we do now. Much more modestly and conservatively. We can't afford to hype the bling bling too much longer, because it is setting us up for failure.

    I could be insane, but this is how I see things, and I hear little to no mention of these issues. I have never heard of a country loosing a "war on terror", but I've heard of plenty that have crumbled from within based on their own perpetuation of short-sighted ideals vs gaining new sights. Ever hear of people wallpapering their houses with money because its cheaper than anything else? Or buying a loaf of bread with a shopping cart of money? Think about how that might affect your life or your families. But do nothing about it.

    Bandwidth is very cheap and getting cheaper and faster. It won't be long before it is faster to download a film than it is to walk to the video store and back. In some places it already is that fast. Besides, most people have unlimited bandwidth deals where if you *aren't* using it, you are wasting more money than if you use it to it's full potential. Most programs can download in the background so that they do not disturb your browsing etc.

    Maybe in some places, but it still takes me 2 to 20+ hours to download about a gig of music (legal for whatever its worth). That is also if the download succeeds. I'm not sure how the filesize of movies or TV shows compare to legal music downloads or if they are more heavily seeded or whatnot. But there is no real content that I cannot save on my 80 Gig DVR in up to HD quality for my monthly cable fee or watch on demand or go to a video rental and get a DVD quality copy on the way home from work for $4 and I can return it on the way to work in a couple of days. Its so much cheaper, easier, more reliable, and higher quality for me to do it that way vs fucking around with a download.

    Because drive space is a scarce commodity? All you need is a gigabyte or two free for the twenty minutes it takes to burn.

    Again, in less than 20 minutes and $4 I can have anything I want in at least DVD video quality. Burnable DVDs still cost money don't they?

    Wouldn't it be simpler if the music industry just decided that downloading films via the internet was a viable business strategy?

    Funny! I would love to hear the music industry decide that downloading films via the internet was a viable business strategy!

    I personally believe that all video and audio entertainment should be purchased like the cable TV model or online porn model. You can get basic service, premium channels, all anal, all lesbo, all prego, or nothing -- your choice. The fact is that for a nominal fee I can have more media than I can even justify my time and money to archive, at least not by default.

    Being that this is information and it is a service, it should be marketed and billed as one.

  12. Interesting on Which CPU Is Tops in Price/Performance? · · Score: 1

    Aside from the HPC circles, I've never really seen a price/performance analysis like this before. I was even more surprised at the results. The P4 3.06 GHz processor came out in November of 2002, the Athlon 3000+ came out in February of 2003 and the P4 3.0 GHz with the 800MHz FSB came out in April of 2003. And these were the winners in terms of price performance with not much more raw performance in the newer and much more expensive chips.

    So, what does this say? To me, it says that SMP and mulitcore is here to stay. We've known this for quite some time for servers, higher end workstations, and again in HPC environments. Its cool to see this trickling down to the more basic end user machines. Although the multicore processors are still new, they are really showing promise. At this time, it looks like the PowerPC dual cores are the best in terms of performance and power handling (they are the only ones I know of that can dynamically power down or reduce power to one core at a time), then the Opteron dual core for price performance, and the Intel x86 dualcore/hyperthreading last. Although I don't have the common slashdot attitude towards Intel, I do believe that they have really lost tons of ground over the past couple of years, and their current offerings in the multicore and hyperthreading hack are not much more than blanks to be filled in the current marketers' scripts.

    SPARCs are supposed to be multicore soon, along with Itaniums, and I guess everything else. AMD has the current lead in core/processor to memory path, but that still needs improvement.

    What I want to see, especially for the "business" or "general purpose" type of machine (read NOT games) or even in the server market is to have more cores, maybe 4 to 8 or so, and have them dynamically come to life when needed, and sleep when not needed. Unless your machine is loaded with adware, spyware, and flash advertisements, when you look at desktop CPU utilization, its very bursty. Usually its at 10% or less of use, and at times it can go much beyond that, and the processor and memory systems should be designed to accommodate this kind of use.

  14. Re:Take a class on How To Get Into Programming? · · Score: 1

    Classes cost money, the value from said money could be great or nothing, with my slant towards nothing.

    I can say that I learned to program by reading code (the non-closed source kind) to figure out how existing programs, the Linux kernel, its build system, etc worked. I never took a class.

    If you're interested in programming, then figure out what kind of things do you want to program. Do you want to do dynamic web pages? I did, so I learned Perl and CGI, and then C, C++, and company. I did things like prototype something quick in perl, and translate it into C. I hacked on the ash shell, I wrote a web search engine, after a few years I could DB program, PHP, C, C++, Perl, and I started creating my own state-machine language.

    Basically, my advice is to program towards some end goal and keep that goal in sight. If your goal is to put Microsoft, Oracle, or Google out of business, be patient. If your concerned with a GUI app, be patient. The best instant gratification stuff are commandline utilities and web stuff.

    Other advice, is to know the difference between OOP and non-OOP types of programming. Although I lover Perl, it is the worst to learn OOP. I would highly recommend C, and the "Programming C" book. I would also recommend the "Programming Perl" book as well as the "Perl Cookbook" if you want to go the Perl route. The Python online documentation is excellent, down to the level that you could reimplement the language from it. The online documentation for PHP is pretty good as well. Ruby is also a good OOP language. I would recommend that or Python.

    Its up to you, follow your interests. Programming is very tedious and time consuming, and much more of both at the beginning.

    I'm completely rambling now, but some things to look forward to learning are things like variable scope, instantiation/variable declaration, casting, passing by value and reference, operator and function overloading, code organization, familiarity with compiling code, knowledge of the builtin functions and/or objects, compiletime and runtime errors, etc.

    If none of that seems interesting, pick a platform and learn assembly :)
