  1. What's really needed... on Tutorial on Linux Device Drivers · · Score: 4
    What's really needed is something that an engineer at a random hardware manufacturer can pick up and run with--not so much the why or even the what of Linux devices drivers as the how. Although Linux Device Drivers is a good start, it's getting a little long in the tooth and will rapidly get outdated with some of the resource management changes that will appear in 2.4 (and are already in the development 2.3 version). New device types like USB (a whole suite of issues here), video capture, and so on, need to be treated, along with better coverage of issues like the SCSI interface.

    Ideally, all an engineer should need to do is find a driver for the device most similar to his/her new device, and follow some general steps in indentifying and making the necessary adaptations. In a perfect world, the engineer would understand the Linux kernel inside and out, but chances are he/she will be completely Linux-ignorant, and will have a matter of a few weeks in which to produce the driver. Thus it would be helpful to draw parallels to Windows drivers (which are likely to be already available or at least more familiar to the engineer), and perhaps cookbook methods for translating them for Linux. Put a limit on theory, history, and other details that don't help the engineer get the job done, fast.

    I know that this attitude might be a bit controversial, but in the real world, non- support for a prefered device is a frequent show-stopper for Linux. Let the open-source community work on making the drivers work well--but there has to be a driver in the first place.

    Let's hope Alessandro Rubini, or someone of his knowledge and abilities, can produce such a book. It's one of the more crucial issues blocking Linux World Domination(tm).

    Excluding evidence obtained by illegal means is often the only way of "punishing" such constitutional violations. Unless the violation is exceedingly flagrant or notorious, it's damn hard to get a civil judgement against law enforcement for such violations, much less a criminal judgement.

    Since the media will generally only report the most spectacular cases, both of excluded evidence and of constitutional abuse, it's easy to get a distorted view. The fact is that very few serious criminals "get off on technicalities," and that petty (and occasionally not-so-petty) violations of constitutionality are pretty common in some jurisdictions. You'll only hear about the cases that sell newspapers or raise ratings, of course...

  3. Mind your business: MS can't make you profitable. on What it takes to be a profitable Internet company · · Score: 1

    No one vendor--even MS--will make you profitable. I'll make some suggestions, but first an obeservation:

    Let's see, just how profitable is Microsoft's portal business? Hint: it isn't. Compare them with Yahoo!, which is profitable (and has been for some time). Guess which one uses Unix? (FreeBSD, to be exact.) Guess which one is located in the SF Bay Area?

    Here's my list:

    1. Run lean. Hire self-managing people of proven experience who add directly to your product. If you need to, hire a few managers to make sure these people received what they need in terms of resources and coordination. Don't "bulk up" management until you absolutely have to. Leanness reduces friction, and means you can respond more quickly to opportunities--or problems.
    2. Listen to your customers. They will be a major source of your ideas, and the first to tell you if you're doing something wrong. Respond to them and personalize service, if you can. One reason there is so little brand loyalty is that customer service on the Internet is almost uniformly terrible. But even a fickle customer can give you a really good idea in the brief time they are around. The Internet makes it easier to listen; use this an an edge.
    3. Plan ahead. Establish goals, but don't be afraid to change them as your business and its environment change. Revisit your progress frequently as you go along. "How am I doing today?" "Where will this take me six months from now? A year?" Things like investments or an IPO are steps along the road, things that enable you to reach goals. But focusing exclusively or even primarily on them is a sure way to screw up your business.
    4. Manage risks. Establish contigency plans for when things fail. If you find yourself spending more than a little time in reactive mode (responding to problems as they appear and dealing with their aftermath) you aren't spending enough effort on mapping out the areas of greatest risk to your business and acting preemptively.

    Failing in any one of these areas--hiring, customer relations, planning, risk management--can doom you no matter how good your marketing plan is. Yet the overwhelming number of Internet startups I've seen have come up short in one of these areas--and more than a few are already gone.

    No, the USPS is a government corporation, like, for example, the FDIC (Federal Deposit Insurance Corporation), formed by an act of Congress. It's quasi-independent in terms of its operations, but it still must refer back to Congress for significant changes (such as postal rates).

    Note for folks who slept through civics class: the Post Office is actually mandated by the US constitution. Another tidbit: because it is legally required to charge the same rate for first-class mail, regardless of costs, the USPS has been given an exclusive right to carry such mail. Given that the US Senate would have to approve a change in this, and that high-cost states have as many senators (though far fewer people) than low-cost states, you aren't likely to see it happen any time soon.

    Compare that with, say, Yahoo's losses per share.

    Yahoo has generally made a profit for the past two and a half years; it would have again last quarter except for the money it spent on acquiring GeoCities and Broadcast.com. (Since those were one-time charges, technically it was profitable.)

    Of course, Yahoo's stock valuation is a few hundred times its earnings--much higher than almost any non-Internet firm. And certainly much higher than RedHat's will be, assuming it actually does prove profitable. That is, unless investors begin seeing as strong a potential for growth in Linux and open-source as they do in the Internet.

    This was my beef with the article: it said that RedHat was less risky than an Internet IPO (which I agree with) but never quite explained why. They aren't primarily an Internet company, nor are they a traditional OS company, yet those are the two things the article compared them to.

  10. Re:It bears repeating on CNet Article On 2.4 Kernel · · Score: 0

    "Linux is 30 year old technology. It's just a notch above Luddism."
    Bob Metcalfe

    Electronic computers are a 55-year-old technology. What's Metcalfe doing still messing around with them?

    As others have mentioned before, WinNT is based on Dec's VMS, an OS that is of the same vintage as Unix. In fact, Microsoft themselves proudly point to this when touting WinNT's enterprise credentials. Why isn't Metcalfe diss'ing WinNT as "30-year-old technology?"

    Claims such as Metcalfe's assume that those who hear them are ignorant of Unix's history. In 1978, when I first encountered Unix, it had maybe a tenth the functionality it does today, even though it was already nine years old. It was 16-bit, it only supported 64MB filesystems, 20 open files was a kernel-enforced limit, file names could only be 14 characters-- it had no networking, no demand paging or other virtual memory features, no threads, and so on. What it did have was the modularity and elegance that its successors, including Linux, have emulated with greater or lesser success as they have extended its limits and added all the modern features of a 1990's OS.

    So Metcalfe should know better. And so should you.

    Yep. And they've sat through enough rah-rah glossy presentations to be pretty jaded concerning those "comforting things" you talk about. They'll go through the business plan with a microscope (and an accountant) before investing. The purpose of these presentations is to get them interested enough to read it.

    RH doesn't need investers playing "buzzword bingo."

You don't hear about them changing SMTP to block email from competitors. Why should instant messages be any different?

    "Direct connection" is a red herring-- if I send email to someone at AOL, my mail agent is making a "direct connection" to AOL's mail servers. The only substantive difference is that they queue the message for later retrieval rather than generating a screen pop.

    There is little difference between a mail agent and an instant messager. Both request passwords to pass to the underlying server. You aren't "giving your password to Microsoft" by using their messager any more than you are "giving your password to Microsoft" whenever you use Outlook. (All bets are off if your mail agent or messager is a trojan, of course.)

Thus any postal system--even if it consisted of a bunch of private companies--would wind up heavily regulated, and thus expensive to run. The current quasi-indendent corporation is probably the best solution, given this mandate.

    Currently, only the USPS can carry normal letters. The argument is that if competition were allowed, competitors would "cream skim" the profitable routes and services such that the USPS could no longer be self-sustaining (since it must, by law, deliver to each US resident), or alternatively the USPS would have to raise rates for outlying areas. Since congress has to approve rates, the latter simply isn't going to happen; there are too many sparsely populated states with two senators each.
