  1. Re:Portrayals of Woz... on Interview: Ask Steve Wozniak · · Score: 1
    I check woz.com from time to time. I think that Woz said on his web site that the depiction of Jobs in "The Pirates of Silicon Valley" accurately demonstrated ONE facet of Jobs's actions and personality, that Jobs could get pretty driven at times, but that Steve Jobs also had other sides not shown in the movie. Still, his comments seemed to say that the movie as a whole was generally accurate as far as the depictions of the characters went, though he wished the depictions had been a bit deeper.

    Unfortunately, woz.com is slashdotted, so I can't go check my recollections at the moment :-(.

  3. Overhead of socket calls vs. direct calls on New XFree86 snapshot - 3.9.17 · · Score: 2
    One of the design goals of the "X" project was STABILITY. There are calls in the Win32 API that will totally trash the GUI, such as (hmm) TerminateThread (I suggest that you read the documentation on MSDN on that one -- you can actually lock up the entire system by using TerminateThread on a program that has made a Win32 API call, is in a "critical section" i.e. has already aquired a lock, and you terminate it before it releases the lock -- all other processes and threads will lock up because they'll no longer be able to acquire the lock!).

    In addition to reducing fundamental stability, the Windows solution also makes it hard to release resources when a thread or process dies. Windows leaks memory like a seive, whereas all "X" resources are tagged and when the OS sends a SIGPIPE to the "X" server to signal that a socket has closed, "X" can release all resources associated with that socket.

    BTW, if you are running the "X" server local to the machine, the socket can be used only for control commands, not for actual data. Actual data would be sent via shared memory. I suggest that you read up on the SysV IPC spec and see why it's not a good idea to send *ALL* data to the video display via shared memory (basically: shared memory does not go away when the process that allocated it dies, and the "X" server would not be notified if that other process died so it wouldn't know to manually de-allocate that shared memory).

    Finally, regarding the performance argument: SGI. I think that says it all. SGI has graphics performance unmatched by anyone -- and runs "X". SGI is perfect proof that "X" does NOT have to be slow -- if "X" is slow, that's an implementation problem, not a fundamental problem with "X". Yes, it's faster to draw directly into a frame buffer than it is to draw directly into a shared memory buffer and then send a command via the "X" socket -- but not MUCH faster, especially if (as with SGI) you have made some optimizations at the OS level for local sockets. I think they have it down to where sending data on a local socket is actually putting it into a buffer, and then mapping that buffer into memory on the other end, somewhere around 20 or 30 cycles. The only real time consumer is marshalling and de-marshalling (i.e., converting the data to a stream, then converting it back to native-format binary at the other end), but that's hardly a killer.

    Exactly. "anyone who seriously wants to develop or beta test". I'm a busy person. Like many geek types, I often work 16 hour days developing a next-generation product for my employer, in hopes that at its release, I will be showered with praise, bonuses, bigger salary, and stock options. I don't have time to be a "serious" developer or beta tester of anybody else's product. I once thought in the past to join the XFree86 development team, but had the exact same problem (except I was only working 12 hour days back then!).

    I do occasionally fix bugs in other people's Open Source software, but not as a "serious" developer. Rather, I download the latest source, see if it fixes my problem, and patch it if it doesn't (and send the patches to the originator). I don't bother trying to fix the source for the "released" version of the program, because it is a duplication of effort if somebody else has already fixed that problem in the latest source, and I do NOT beta-test software that I do not have source code to -- I want to be able to pop it into gdb and do a stack trace if it core dumps, and be able to send a patch as well as a bug report to the author.

    Not that I beta test things very often. Usually it's on a whim. E.g., I downloaded the KDE 2.0 betas (1.8?) and compiled them with debugging on, simply because I was feeling frisky one Saturday afternoon. I tried it out, said "hmm, nice, we'll see what happens when the rest of the KDE programs are ported to this", and went back to KDE 1.2. But the point is that, by not requiring me to jump through hoops, this was one more eye that looked at the program. Not a seriously deep look, mind you -- I did not (and do not) have time to be a serious beta tester -- but still, eyes are eyes.

    I understand the problems that the XFree86 team faces insofar as NDA's are concerned. After all, the whole reason for forming XFree86 Inc. was to have a corporate entity that could sign NDA's with video card manufacturers. But I am telling you that this IS a reason why the XFree86 project has trouble attracting developers -- the situation adds a hoop to jump through for someone like me, who doesn't have time to be a "serious" developer. Not a seriously high hoop, but hey, I'm not being paid to develop XFree86, y'know, and any barrier at all to participation is too high a barrier for someone who wants to make an occasional casual contribution. I don't have any facile solution to the problem, certainly nothing as simplistic and moronic as "fork the project!" or "boycott NDA-requiring video card makers!". But to deny that it is a problem is to deny reality.

    The words that follow that statement are not law. They are not legally binding. But I still believe that this is truth: that "all men are endowed by their Creator with certain unalienable Rights".

    In general, legally-guaranteed rights are not subject to contracts. Many neighborhoods here in Phoenix, Arizona, are deed-restricted with wording along the lines of "you may not sell this property to those of Spanish blood, or to Negros, or Irishmen." This is a contract that is agreed to when you buy the property, and that before the passing of various civil rights laws was enforced regularly. But a contract cannot be enforced if it violates the Constitution or the laws of the United States of America, such as the 1st Amendment right to freedom of the press as was exercised by Slashdot's editorial staff when they posted links to the DeCSS program.

    We once had an institution in this country called slavery. It was legal. Most slaves had been legally sold to slavers under the laws of their home country, and the slavers then legally re-sold those slaves to landowners in the Americas. I mention this fact to go one step further than the legalistic argument, which is to say that there ARE rights granted to us by our Creator, and among those are freedom of speech and of thought, freedoms which are being violated every day via "contracts" in which we voluntarily enter servitude in exchange for a livelihood. I could be working for twice the money today if I were willing to sign contracts granting my employer ownership of all ideas and software written while I am in their employ (even ideas thought at home, and software written at home, on my personal time). I will not do that, thus I work for small businesses that are grateful for quality people (grateful enough to overlook my refusal to sign such contracts) but which cannot afford to pay real money.

    Enough meandering. But the point is this: That laws and contracts which violate the rights and freedoms granted to us by our Creator exist, and that we are right and just when we protest and try to overturn these laws and contracts, whether they be deed restrictions which prevent Hispanics from buying houses in choice neighborhoods, or a frivolous lawsuit intended to impede free speech on the Internet.

  13. Capitalism vs. corporatism on Pick Your Own Net Person Of The Year · · Score: 2
    There is a big difference between capitalism and corporatism. Capitalism is a system where buyers and sellers meet and exchange goods and services. Corporatism is a system where state-sponsored "limited liability corporations" are given the right to behave like "artificial people" but where the individuals who own and/or run said business are not held individually responsible for their conduct. Corporatism is a system where these artificial state-created entities are granted special rights by the state at the expense of the rights of individuals. Corporatism is a system where a mid-level executive can decide to poison the water and not be charged with murder when a child dies as a result of that decision but instead, be given a bonus because the out-of-court settlement was cheaper than upfitting the factory would have been. In short, it is a system where individuals are forced to enforce the laws by sueing criminals in civil courts, rather than having the government that we elect protect us from those criminals.

    So please, do not confused capitalism and corporatism. Capitalism existed before corporatism, and the only "plus" of corporatism is the same "plus" as fascism (which is a version of corporatism with the state more directly tied to the corporations) -- it's a great way for increasing the wealth of the individuals in power.

Then you can mix it down using any digital mixer software (all of the professional-quality software runs under Windows or Mac, sigh, but you can get decent software for well under $500) and voila!

Having attempted to do some recording myself, I can attest that it takes a LOT of work to make it come out right... e.g., a typical problem is "too hot" miking (clips your input) or, more insidious, "too cold" miking (ends up sounding muffled because you lose some of the dynamic range). The problem is that the "heat" varies depending upon your playing style, placement of microphone, mixer settings, and sound card input settings, and getting all of that right is a pain in the @%@!.

The worst mix I ever heard was for a South Louisiana band called "The Bluerunners", which played "accordian grunge" (my best estimation of what they played). I'd heard them live at the Breaux Bridge Crawfish Festival and loved their sound, which was hard-driving, distorted, and mixed to perfection -- think grunge before grunge was cool. Then I bought their CD. *BIG* mistake -- the mix was clear, put the vocalist up front instead of as a background to the driving guitar and accordian (he was NOT a good enough vocalist to be up front!), and it would have been a great mix for Simon and Garfunkel but *NOT* for the BlueRunners, who needed a grittier, grungier mix to duplicate their live sound.

    Anyhow, the expertise of a good recording engineer, as noted above, is probably the only thing you can get by going to a studio that you can't cheaply do at home with your PC, but as the BlueRunners example shows, it doesn't always result in a good mix (grin).

    2. Once they had their excuse, rioting was deliberately provoked by the police using tear gas, rubber bullets, and pepper spray in an effort to get an excuse to invoke martial law.
    3. Once the corporate media had compliantly reported that all of the protesters were "rioters" (rather than the 40 or so black-clad punks who were the only rioters in the area), the mayor and governor declared martial law (or, rather, "a state of emergency"), and dispatched the National Guard to clear the streets. Possession of a gas mask was also declared criminal intent, and you were immediately arrested if you had one. National Guardsmen and police officers blocked all entrances and exits from the area and stopped all who wanted to get in to ask them for identification and about their business in the area (shades of USSR!).
    It was not reported on the national media, but one of the so-called "riots" was actually residents of the Capitol Hill neighborhood protesting the police presence in their neighborhood.
