Inspiring Adventures in SF Wireless Networking

JimDog writes "Here's a description I wrote of how I set up a point-to-point 802.11b link over 3.5 miles for Internet access at my house. The link runs at 3.5 Mbps, which I barely make a dent in, and I'd like to offer the rest of the bandwidth to anyone who's got line-of-sight to my location in San Francisco." The great thing about this story is both his terrific exposure to different parts of city and his willingness to share. It also makes it clear just how easy it is to set up a long distance link.

    28 DAYS UNTIL LNUX IS DE-LISTED FROM NASDAQ!!

    Subject: When times get hard

    It hit the papers today that VA Linux Systems is going to have to cut 25% of its staff. The press release, as usual, was bland and neutral,
    emphasizing our healthy revenue growth and our bright prospects -- the kind of corporate-speak everybody expects, and that VA has to
    generate. It's part of the game.

    It's no secret that I'm on VA's Board of Directors. I was at the board meeting where the five-odd people who have the responsibility to advise
    Larry Augustin told him what he had to do. I was part of that decision, and it was not an easy one.

    I'm not speaking for VA now (I basically never try to do that anyway; it's not my job). I'm speaking for myself. It was a weird, wrenching feeling
    to wander around VA headquarters that afternoon, talking with good friends of mine, knowing in a few cases that they were likely to be canned through
    no special fault of their own.

    What VA is going through now is a sort of ritual bloodletting. The logic of the market is pitiless; when you don't make your numbers, the investors
    want to be appeased by evidence that you're doing things to raise your profitability. That means making more dollars per employee, and the
    fastest way to get there, the way investors effectively *demand* that you get there, is by laying off your least dollar-yielding employees.

    Otherwise, you get what is politely called "loss of investor confidence". Companies go on life support when that happens -- they
    can't get capital by selling shares, and that has ripple effects -- it tends to make potential customers bolt. When the customers bolt, the company runs out of money and die. Or it gets acquired, either by a large competitor or (worse) by a slice-n-dice artist who will sell off the assets and shitcan the company.

    I went along with the 25% cuts because I understood the possible alternative: no company. And no employees. And no possibility that
    my friends will ever be able to come back to work for a company they still love and care about.

    I think VA's problems are solvable ones. The company got rocked by the popping of the dot.com bubble and the economic downturn we're in.
    But we know what we have to do to deal with that. In order to avoid making what the SEC calls "forward-looking statements" I'm not going
    to talk about our strategy or future prospects here; you can go ask VA's corporate-communications folks about that.

    But the real reason I'm writing this little broadside is larger than VA; it's about the state of the open-source community, and the things
    we need to keep in mind when times get hard.

    VA, along with Red Hat, is one of the two bellwethers of the open-source business community. Some people are going to freak out
    and think this setback is a harbinger of doom, that it means our community's game is over. Some people, especially at certain
    monopolistic closed-source competitors I don't need to name, know better -- that troubles like VA's are pretty common in a market
    downturn
    -- but they'll use it as ammunition in a FUD campaign anyhow. Expect to see Steve Ballmer and Jim Alchin quietly gloating at any
    trade-press reporter they can collar. Brace for it.

    And, as it says in large friendly letters on the back of the Hitchhiker's Guide, DON'T PANIC! What we're seeing now is entirely
    normal.
    It's the long, dizzy boom time that has just ended, all smiles and champagne and venture capital sloshing around looking
    for business plans, that has been exceptional. Business cycles happen, there are layoffs and retrenchments all over the economy --
    and this, too, shall pass. Things will get better.

    There is actually one good thing for us about economic slumps. During them, IT departments and software users in general feel pressure to cut costs. That makes low-cost and free software more attractive. Over the next few months you can expect to see a lot of submarine Linux deployments suddenly surfacing as managers realize that they'll look *good* on their quarterlies if they cut their licensing and service costs, and as the techies working for them get that message
    and fess up to how many NT boxes they've been replacing by stealth.

    So the downturn isn't all bad news for us, by any means. We just needto keep doing what we're doing, the best work we can. And when the
    economy picks up again, we will have gained by it.

    Back at IPO time I wrote an essay called "Surprised By Wealth" in which I tried to deal with how weird it felt to have a theoretical net
    worth of $41 million.
    Am I upset that all that "wealth" is gone, at least until the stock bounces back? Well...yes and no. As a member
    of VA's Board, it's my job to worry about our stock price, on behalf of all of our stockholders. So I care about that.

    But personally? Nah. I wasn't in this for the bucks then, and I'm not now. Like most hackers, I do what I do for love and I thank the
    gods that I can occasionally talk people into paying me money for it. Feels almost like taking advantage of them sometimes, doesn't it?

    All the corporate stuff is not, after all, the point -- the point is to change the world, to do better software and give users more
    choices. It's been a nice party, but some of us did get a little distracted by all that easy money flowing around. If the slump does
    nothing else but take our eyes off those dollar signs and put them firmly back on the work, maybe it will have been the best thing for us
    after all.

    I'd imagine that the Howard area has something similar to this considering the kind of government grants they get to promote the Computer Science department at the historically black university.

    Frankly, Howard's got the best CS program in the DC area.

    The funding's a good idea, that's for sure. Minorities are severely under-represented in the programming field.

    I just switched to winXP. Can anyone imagine how fast it is. Reading ./ I was under impression that XP is an eye candy only. No TRUE. It rocks. It needs just couple seconds to start. It beats Win2000 like a roadrunner.
    To fully utilize this bandwith you might need WinXp.
    My download speeds are 10%-20% faster since then. So before you start with this wireless internet, make sure to have right software for it.

      I don't get it. that doesn't have much to do with the article...

      Besides, I've seen XP run slower than other MS operating systems. IMHO, Win2K is the best of MS's offerings so far.

      In reality, I use Linux and Mac OS X, both of which run much more stable, secure, and efficient than anything Microsoft has come out with.

      Getting back on topic, I have an 802.11b card for my PowerBook. It's not an AirPort card, it's one of those Orinoco cards. Nobody makes OS X drivers for any of their cards except Apple. In order to get this card to work, I had to get open source drivers from http://wirelessdriver.sourceforge.net/ and it works quite well. Compared to the Orinoco drivers under OS 9.2.2, I don't see a difference. So, perhaps before your switch to WinXP there was something misconfigured, or perhaps bloatware or spyware or a virus taking up bandwidth and whatever it was got wiped out during the upgrade. Just a theory.

      Hmmm, still not on topic. OK lets try this... This guy in SF is crazy, but in the good way. Maybe someday I'll set up a rediculously-long-distance WAN just for kicks. Hmmm I'm supposed to move within a few months, maybe then ;-}
