    Isn't this probably the exact same thing that's been done on diesel submarines for the last half a century?


    No, not actually. Submarines (the non-nuclear variety) run on diesel engines while surfaced, but on battery power while submersed. Your typical garden-variety WWII sub could stay underwater for about a day before it had to surface to recharge its batteries. This made German U-boats (and other subs too, I'd imagine) quite vulderable to attack (the surfacing was to the tune of several hours) until a snorkel was developed to allow oxygen to be breathed into the motor without surfacing the whole ship.


    So no, though there is probably a small amount of reuse of some exhaust gasses, previous diesel subs still need to breath air and operate on battery power while under water.

    We do it that way. Once someone applies for and receives his account information, we send them to their floor's RA who has a couple of instruction packet to lend out. The packet walks them through installing basic Windows networking services, then they login with a generic "newuser" account, which automatically upgrades their Novell client to a modern version. We then use Novell's Application Launcher to install Netscape and McAfee virus protection--one click install for each. Netscape settings are downloaded from the login script; DHCP provides IP configuration; and we give them basic email account configuration instructions.

    We leave it up to the user to get their network card installed. Some of them have their friends do it, some do it themselves, and others pay us during our off-time. For those who either can't figure out the packet, or have problems with the procedure, we schedule a time to visit and get things working for them. We update our instructions periodically as we discover common problems and solutions to those issues. I suppose the toughest part--anywhere--is the fact that we're dealing with all sorts of different computer models. Some certainly present interesting quirks.

    We're a fairly small school, and not everybody has computers, so it goes pretty well. There's only a couple of us to handle it all. Word gets around and users help each other out quite a bit.

  10. Here's a couple more on What Makes You "High Risk" For SPAM? · · Score: 3
    In my experience, spam could be delved out a few other ways as well.

    First, I have a hotmail account. When I get mail in my box that is addressed to every variant before and after my name, alphabetically, I figure that's just a buckshot approach to hitting a few addresses that might work. 'Course, I have no scientific way to demonstrate this except the suspiciousness of such CC: headers.

    Second, what about email forwards? My mother-in-law is big on forwarding cutesy stories and inspirational things, as well as those fake virus warnings (when some guy was first telling me about Melissa, before he said he saw it on TV, I thought that was another one of those) and "email tracking for money/candy/cure for cancer/etc" messages. We all know someone who constantly sends stuff like that, likely. While some people even consider that borderline spam, I think the larger problem is the long list of headers, containing addresses, that end up in nefarious hands at some point or another. Again, I have no proof, but I'd bet that this kind of thing is a good way for spammers to get email addresses, when my name has been included in a long string of names on somebody's chain letter.

    The problem with the second method could be greatly alleviated if people would a) clean up messages they forward; b) learn not to forward the obvious junk (a nice story or good joke occasionally is ok); and c) use BCC: instead.

    The article first showed up on the front page, but disappeared sometime while I was reading the comments. However, the topic "slashdot" icon was still on the top of the screen. Strange, but I don't know how the site works in that regard. I thought maybe they reclassified the site and thought it wasn't good enough for the front page.

  14. but the Internet and other media are not the same on Banner Ads: Biggest Advertising Mistake Ever · · Score: 1
    In other domains, no one judges the success of print ads by the number of people who stop reading the magazine and rush to the phones, they judge success by the overall increase in business. Likewise, no one judges the success of billboards by how many cars veer off the freeway and head towards the advertiser's business, nor TV advertisement by how many people shut off the TV and run to the mall. However, that is exactly what is used to judge the viability of banner ads - it is expected to provide instant business, and advertisers are loathe to pay for online ad campaigns that don't have a next-click success.

    Maybe instant business is not the key, but arguably web pages create an environment where it's a lot easier to say, "Hey! I've been looking for one of those!" [click]. It'd be pretty difficult to stop and buy something advertised on the latest billboard if you're on your way to work, but web pages make that quite a bit more convenient--heck, you can do it while you're AT work.

    Moreover, just as easy as it is to click on banner ads and buy something right away, they're also tons easier to ignore. So they fail to create the branding impression in their viewers that TV commercials and billboards are a little more effective at. Sure, you can change the channel, hit the mute button, look away, but if you ask me, banner ads are even more ignored than that. At least, I don't pay much attention to them.

    So while you have a valid point, I don't think the comparision can be complete, as the Internet is a different beast than the traditional media of the past.

  15. Education is one key on Maintaining Computers Donated to Schools and Charities? · · Score: 3
    I realize that this doesn't really answer the question, but from my experience, I'll have to echo Cliff's comments. Sometimes we need to help the less-knowledgable understand that sometimes it isn't worth the trouble to hang onto these old computers.

    Naturally this occurs on two sides: those who are giving and those who are receiving. Companies that can afford to upgrade their equipment probably want to offload their old equipment for a tax write-off. Heck, they probably take a write-off for what they originally paid for the equipment. They need to realize that, depending on the age of the equipment, they really aren't doing the receiving institution any favors by sending them equipment. Sure, a graphics design company might not have much use for last year's P-III 450s, but 486s, early pentiums, Mac classics, and older might prove to be too much trouble for exactly the reason brought up in this question.

    The other people that need to be educated are the people accepting the equipment. I can't think of how many times we have had to explain to the administration around here that those old computers just weren't worth it, and that we couldn't make them good for anything. If they *could* be upgraded, and we were going to try, our money would be a lot better spent on purchasing newer machines.

    Also, those who donate equipment, as this article mentions, need to donate it right away. In the given example, I wonder how many companies had computers sitting in back rooms and closets for over a year? I realize that donation can't always happen right after they upgrade to new eqipment, but all too often, stuff probably just gets forgotten about and then a year later it's even less worth the upgrade. At least the eqipment might be old when they donate it a little earlier, but it might still be viably (is that a word?) useful for someone, and there still may be some old accessories and software available.

    Ok, maybe I should throw in some suggestions for use, too, if people really do want to hang onto this old stuff. I have seen smaller computer stores (not Best Buy or Wal-mart, mind you) and especially salvage parts suppliers carry older hardware and software that perhaps these old machines can use. If it's a school or other non-profit institution, and one copy of an older, useful application could be obtained, I bet if they'd write the software company, they could get permission to install older software. The software company could even consider it a donation, and it wouldn't even cost them anything. Also, older programs might be available via online auctions as well. Or even those reverse auctions where you mention what you want. I imagine there's tons of people out there that have old stuff sitting around in their basements, they just don't know anybody wants it.

  19. Macs and NetWare != convenience on How Viable is a MacOS-to-NetWare Connection? · · Score: 2
    Let me explain some of our situation in connectiong the few Macintoshes we have left to our NetWare network. First, the details: we have a small NDS tree including a NetWare 5 fileserver running ProSoft Engineering's NetWare 5 Services for Appleshare, which (in theory, and in the past for us) allows Mac users to access the fileserver and its volumes through the chooser. We also have a NetWare 5 server running BorderManager 3.0 as our firewall/proxy.

    Sometime around service pack 5, ProSoft's product stopped working for us. We really didn't notice too much because our Macs are not that active, so we were slow to respond to their reports of it not working. By the time we got service pack 6 loaded, Novell made some key changes which convinces me it's not GOING to work until ProSoft releases some more patches. Long story short, we don't have that working any more. It's been a nightmare. There is a separate IPX client, however, requiring a separate login, also from ProSoft. In the *past* it has worked fine for us, but our Mac people insisted on being able to use the chooser, so we haven't pursued it that much. But for someone that's willing to be reeducated a little, there's nothing wrong the the native Mac client.

    Maybe you're not interested in accessing files on any of those servers (and from the sound of it, the state network is not about to load a 3rd party product). But if you want Internet access, that works well, most of the time. Now depending on how they have their firewall and proxy configured, there's not much more to it to get a Mac connected other than get an IP address and configure your browser for the proxy server, if there is one (you can pretty much duplicate the settings from Netscape for Windows). YMMV, but here's the quick rundown on how we have our Internet access configured. We use a proxy server and block quite a bit via our firewall (both incoming and outgoing), and track proxy/web usage via NDS username. Thus, when we configure a browser to use the BorderManager proxy server, it tries to figure out who is requesting access. With Windows, there is a nice little utility that works in conjunction with Client32, clntrust.exe, that will tell the proxy server who the logged-in user is. If that isn't loaded--it's not available for Mac--it brings the user to a secure web page and asks them to enter their NDS username and password. That's all there is to it, and it works fine. Any trouble we have is usually NDS, not Macintosh related.

    Now as for the stories you get about why the powers that be don't want you to hook your Macs up: (I assume you don't have them networked at ALL?) I admit I'm no Mac expert but this is what I've heard and experienced. Appletalk is a chatty protocol, but it doesn't bring our network to a halt. I wouldn't say it's any more chatty than SAP and other IPX related traffic, so if they still use IPX, who cares? Plus, if you're speaking of a multi-site WAN, aren't there firewalls and routers that would filter some of this out? If you're using TCP/IP from the Mac exclusively to get on the Internet, the rest of the WAN won't see the Appletalk traffic.

    As for MacOS being unstable or hackable, well, I find it kind of unstable too sometimes, but so is Windoze. It's really the user's concern if his machine crashes while he's using it. I *don't* think it's all that prone to being broken into. Windows machines are probably worse off in that arena. And again, so what? Don't they have firewalls from the outside world preventing this kind of thing?

    As for them having a personal vendetta against Macs, well, my department and I have the same vendetta against the remaining Macs we have on campus. :-) But I bet if you have enough control to get some IP addresses (we use DHCP, which helps) and configure the machines, they probably won't even notice. Your Macs will function safely, securely, and unnoticably on their network, even if Novell is involved (not that that even makes a difference). I don't have any sort of research to prove it, but I do have similar experience to share.

    Hope that helps.
