  1. Re:News for who? on Return of the Vacuum Tube · · Score: 1

    All the top guitar-amplifier makers' top-of-the-line pro-level models brag of being "all tube". DSP has not yet been able to equal the tone, "feel", and response to the player's nuances that vacuum tubes exhibit. It's really, REALLY hard to model all the variables that affect the sound of an electromechanical device like a vacuum tube with digital signal processing.

    It has more to do with reputation than with "can't be done otherwise". A 50 cent-a-pop DSP probably has enough power to simulate the good ol' vacuum tube sound. Of course, that's today's reality, and not when transistorized power amplifiers started to be common. At that time, many respectable brands did produced superior high-power amplifiers using vacuum tubes, and people liked their sound. It also helped that most of those brands produced crappy transistorized amplifiers (often using generic switching power transistors, instead of high-quality audio ones), so the warm sound of tubes caused even more contrast with the metallic sound and lack of dynamic range of transistorized versions.

    I build and sell custom vacuum-tube guitar amps myself, as well as provide service and repair for vintage & modern tube guitar and bass amps. I can also occasionally be found on a stage in a club, or on a festival stage somewhere, playing guitar. I've been doing both for about 4 decades now.

    And yes, I do prefer the vacuum-tube amps, not only because of the sound, but also the warm feeling of old electronics :)

    So, why not combine dozens (or hundreds) of transistor output stages to get the equivalent of a single valve-based amplifier?

    To a smaller scale, that is already done. A darlington configuration will give you a nice amplifier (given that you don't mind about distortion). Class D amplifiers will usually have 2 symmetrical darlington sets that drive the output, but with a ton of other issues. Multi-stage darlington (H configuration?) will often give you a pretty powerful noise generator.

    Smart investors will not buy on IPO. Smart investors will _sell_ on IPO (there are a lot of investors shielded as a single entity that will get a piece of the pie). Other smart investors will wait (at least)a week or two until the price settles and there is a clear tendency (both to buy or to decide to sell). Lots and lots of investment portfolio subscribers will make their money (or lose their money) on high-frequency trading and short-selling. Either way, there is plenty of money to be made.

    I'm afraid you have #2 backwards friend, as in 2002 the FPS genre combined with the MHz wars was causing PC gaming to explode

    From http://en.wikipedia.org/wiki/Game_Developers_Choice_Awards:
    2002: GTA III - PlayStation
    2003: Metroid Prime - GameCube
    2004: Star Wars: Knights of the Old Republic - XBox

    2008: Portal - Windows/Xbox360
    2009: Fallout III - Windows/Xbox360/Playstation
    (...)

    Do you see a pattern? I do. And, in 2002, you did have awesome games for PC, if you forked over about the price of a console for a graphics card that would become obsolete 6 months later. So, not that different from today.

    whereas the consoles at the time were looked at as more "toys for teens" than for serious gaming.

    You mean those state-of-the-art, almost noise-free entertainment boxes with a bundled ethernet connection, that people could use to play CDs, DVDs, play games and that didn't catch any of those nasty virus? And didn't took forever to boot?Those systems that a 3-year old can operate?

    One could argue that this is one of the reasons for the design of the original Xbox which was nothing but a highly specialized Windows gaming PC

    The problem was that DirectX, while a superior technology at some levels, wasn't that useful for gaming companies if you couldn't also use it on a console. And the competition (mostly OpenGL) not only was quite simple to program to (DX5 was fully OO), but easier to port to other platforms.

    In any measure if you look at Ballmer's reign, even if you give him the Xbox as a success (which it is still debatable if they are in the black on the X360) and compare successes to failures most would say he has been a terrible CEO.

    I did not say anything otherwise. I was just merely debating the "obvious fiasco of XBox". I do agree that Microsoft has, once again, missed on a gold mine by not being able to innovate. Maybe that's Ballmer's fault, but I've seen companies innovate the last decade and - while creating brilliant and inovative products - they failed miserably as a company. Yahoo and SUN are good examples of that.

    So I'd say by whatever metric you use simply by the huge amounts of capital he has blown on one failed venture after another should put him squarely in the top 5 worst CEOs.

    I don't know if you are aware that it was usual for game studios to have exclusive contracts with a given console brand. Before XBox, you didn't get many cross-platform titles, but now you do. There is the early release date (usually for a specfied console), but after a period of time, you usually can get a release for at least other platform (usually windows). I'm not aware of the exact fee for driver certification and to be able to display the Windows Logo on the box, but I'd say that probably a big chunk of those losses have been covered by graphic cards manufacturers.

    I'm not really into gaming, nor am I familiarized with the details of the consoles available, but it was expected from the start that XBox would not be a money maker. The way I saw it, the two main goals were 1) to get a foot on the home entrertainment business (and avoid colossal mistakes like the Microsoft Network thinggy) and 2) keeping game development companies interested in the Windows/PC market. 10 years ago, the tendency was that "top of the line" games would come out for consoles, and then several months later (if ever) to PC. In many cases, porting to PC wasn't a trivial task (because by then, OpenGL was already a second-class citizen), and many gamers were fond of the simplicity of the consoles (cheap big screen TVs and good sound systems also helped).
    The royalty policies were (probably still are) quite appealing - specially when comparing to Sony, the SDK is full-featured and cheap (I'm not shure if it is free, but even if so, you'd pay the VS suite to get all the features), and developers can target multiple devices with almost no effort. So, to calculate the actual cost of XBox, you need to factor in the value of the development community, hardware certification fees and online services revenue.

    Well they can continue to watch Microsoft and Apple pilfer their software stack usually giving nothing in return

    You sound very worried about that. There are other cases, such as the ton of Linux distros that use BSD software (the big example is probably OpenSSH) and give nothing in return. Other companies (such as Apple and iXsystems), employ BSD developers and sponsor - directly and indirectly - development. What is your point?

    while they can use GNOME or KDE or whichever other GPL or LGPLed project exists on their system (takes only a recompile)

    I'm a BSD user, and I only have a (development) VM with X and Gnome. Every other system doesn't even have X installed. And if you think that running Gnome on BSD is a recompile away, you are sadly mistaken. Just because there is a port of it, doesn't mean it doesn't take a lot of effort (and in some cases, loss of funcionality). Also, many BSD desktop users are "advanced" users - I'd say it's way more common to see minimal/tab based windowmanagers than Gnome or KDE.

    they don't have a useable desktop

    What is a useable desktop? Because many opensource desktop applications aren't GPL, so the same principle applies to Linux. Because, you know, X/Xorg itself isn't GPL. And most of Mozilla Firefox. Did Microsoft and Apple also pilfer it?

    Apple just wants to clamp down everything to be BSD so they can batter down all hatches eventually for the day when they give nothing back.

    Yes, because BSD developers are usually paranoid about the possibility of maybe some evil company use their code. Or they just don't care, and choose a license that expresses that.

    There has been some effort in replacing GCC in BSD systems at least since the 2.95 shift. The GPL licensing of GCC was always obviously a problem, but the discarding of some architectures and the bloat of the latest versions did not help either. A couple of years ago the OpenBSD team did a port of PCC to replace GCC as the base compiler for the system, and for a "big" operating system like FreeBSD, compile times do make a difference.

  17. Re:What's wrong with GCC? on FreeBSD 10 To Use Clang Compiler, Deprecate GCC · · Score: 2

    No only licensing issues, but also performance. While CLANG may not have all the bells and whistles of GCC, it does a good job compiling C code - and given that the base system is mostly C, even a small improvement in compile time (and memory usage) can make a big difference, specially for those who - like me - prefer to build and upgrade from source.
    Another motive to seek alternatives (but not directly related to FreeBSD) is the lack of support of some architectures. Some "obsolete" architectures were removed post GCC 2.95, but some BSDs still support them today. Having a easy to port, actively developed, BSD licensed compiler is way better than to rely on some archaic GCC version.
