I should add that while the possibility of becoming a supernode is a real
possibility for Larry and machines that are connected all the time, for most boaters it is not really a problem. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Intentionally so to prevent it being blocked. Cable and Worthless BVI has successfully blocked vonnage because the source IP is easy to detect but have not found a way to block Skype. As I understand it, if Skype runs into a block it will try connecting through a series of different "supernodes" until it finds one that can sneak around the block. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

If Don is on a cable, Skype software may identify his connection as a supernode, thus Don's $50/mnth bandwidth is used to route calls for Skype, not that they let Don know that that's what could happen nor does Skype reimburse Don for the use of a service that Don is paying for. Not true. actually Larry what I wrote is true Skype uses your connection to route your connection data through and passes those connected through you their contact list and who's online. It does NOT, route any calls, whatsoever through your system. actually Larry, the software does use your connection to route calls and if you are unlucky enough to be tagged as a supernode, the system will use your bandwidth -the bandwidth _you_ pay for, to route _many_ calls. This seems simple to me. Mine's been on it for a long time. It's bandwidth usage is undetectable, even on limited bandwidth DSL. I'm on a 7Mbps cable connection through a wired/wifi router, sometimes with 3 Skype devices running at once. Perhaps reading more carefully might assist. Your connection -fast as it is- probably has not been co-opted as a supernode -without your knowledge or informed consent- which is the way Skype works. It has made NO difference in my constant usenet downloading or it would have been gone long ago. well then, perhaps you've been lucky 2. Proprietary software/encryption/protocols that according to the head-honcho at Skype "will not pass OpenSource auditing for security". AS I don't send state secrets over Skype's connection, I doubt anyone will become enthralled with my Skype conversations with Skip aboard Flying Pig about...snip that isn't the point is it, but then it seems that while you resent "state-snooping", other forms of snooping -or the potential for it- are alright with you. Seems a contradiction to me. Whatever makes you happy. |

I'm sure it takes more bandwidth to become a supernode than is available to most boaters. Even if you're getting full wifi bandwidth both ways, it's likely your wifi connection is hooked to a cable, DSL, or ISDN line with no more than 128k upstream, if that. Even with 256k upstream on a cable connection, I never went "super." I wouldn't worry about it. Matt O. |

I'd prefer Mac or Linux too, but boats usually need a Windows system aboard to run navigation software. I do wish there was a good nav package for Linux. Matt, Check out http://www.vmware.com They have an alternative OS solution, but it costs money - not a lot, but enough to warn you about. They make a Virtual Machine simulator that runs as an application on most of the common operating systems, including Linux. The advantage here is that you can run Linux (for free) as your host OS, then have one or more "virtual machines" running as applications that could run a full Windows2000, Windows98, WindowsXP, MAC, etc., each independent of the other and unaware that they aren't the primary OS. VMware also allows the virtual machines to have (at your choice) network connects (via the host OS) to the outside world - or not. So, if you want to use MicroSloth products (because your favorite apps don't support Linux yet) but you don't want to expose yourself to the vulnerabilities of such a buggy and unsafe OS, you can install them without network availability, run your favorite application, and eliminate the security risks that networked Windoze systems impose, all the while using Linux connected to the outside world. Amusingly, when one of these virtual OS's decides to crash, your computer (and its native OS and any other VMs) keep working along merrily. So, although you may be used to the blue screen of death from Mr. Gates, all that happens when your VM version crashes is that you "reboot" that particular "application". Another huge advantage is that each VM can be assigned a fixed amount of disk space (I tend to make these separate partitions on the native OS but you don't have to) and you can "back up" the entire VM (as one single file - think of it as a full disk copy of a traditional system. The only down sides I can think of are 1) you need to buy VMware, 2) that VMware tends to need a lot of memory, so you pretty much want to max out your RAM (which is nowadays very cheap), and 3) that you need a stand alone install disk for any "client" OS's you want to install. The last bit is true independent of VMware. It was a dirty trick MS started using when they realized that folks might want to "reuse" their software on other machines. What most folks didn't realize is that when that bought that laptop or desktop "bundled" with Windoze, the OS that came with it is "hacked" to only run on that specific machine. If your laptop or desktop died, that OS disk that came with it can not be used to install Windows on another machine. So, get a decent laptop or desktop, max out the RAM, install a 40gig (or more) disk, install Linux as the native OS, purchase VMware, create one or more Virtual Machines (allocate 3 gigs of disk space to each) onto which you then install one or more versions of Windows or MAC OS. This approach, BTW, is also very useful for being able to maintain applications that are no longer supported on newer versions of your OS. Just run both OS as VMs, and when you need to use an older application, switch to that virtual machine. Cheers, Robb |

Well, I don't wish to make absolute claims here, but I very much doubt
it. One reason being that MS (unless installed from a stand alone version) is hardwired to run on the specific hardware it came bundled with, but MS restrictions not withstanding (I also don't believe) there is any utility that currently does this within VMware. A better approach might be to copy everything of interest off to an external drive, then attach that drive to the new Virtual Machine and copy everything from it onto the local drive. This would work fine for data files and such, but MicroSloth goes out of its way to make the applications (unlike Linux) difficult to install. My guess would be that you need to rerun the installer programs - and some of the new application installers might object to being installed on a machine (virtual or otherwise) that wasn't connected to the network. Of course, the best approach is to avoid using such a blatantly inferior OS in the first place, and there are free utilities such as "wine" that supposedly can run Windoze binaries directly from within Linux, but I personally do not have any experience with them. I would suggest asking one of the Linux support groups about that. If you do go with Linux as your base OS, I think you should make sure to download the Mozilla "FireFox" browser and "Thunderbird" emailer apps, as well as the free "Open Office" suite of tools (an editor that can handle almost any standard file type including the various MS Word files, a spread sheet that can handle Excel as well as other file types, Drawing programs, photoshop like programs, etc. All for free. Oh, BTW, there are MS based version of all these tools as well. Check out http://www.mozilla.org and http://www.openoffice.org (be sure to use the .org ending) Also, as for particular versions of Linux, I would recommend the Redhat Fedora Core4 version. If you decide to go that route, I suggest you download the DVD install disk (instead of the 4 CD ROMs). I found this to be far easier when installing the system. Check out http://www.fedora.redhat.com/download/ One warning. If you start using a UNIX based operating system for any length of time you will find yourself wondering why it isn't crashing periodically. Do not be alarmed, there is also an MS crash simulator that you can install which will randomly put of a simulated blue screen of death allowing you to feel more at home. Over time you can ween yourself off of the need to see this pacifier. In a world without fences, who needs Gates?

Fortunately, stability is not a big issue for me using a fully updated and protected Win 2K. I can't remember the last time I got a "blue screen". Just lucky I guess. |

I'm well aware of VMware, having used it since pre-1.0 beta for testing web platforms. It works great, and is the basis for most web hosting companies offering VM hosting. It's overkill for personal use though. By the time you buy a VMware license plus a Windows license for your Linux laptop, you could almost have bought a new laptop which comes with Windows anyway. A desktop might actually be cheaper. Even under VMware, Windows still has to restart when it crashes. Maybe it does a little quicker but not much. And you're still stuck with Windows' cluttered interface when running your Windows programs. So you don't gain a damned thing by doing this. Engineering issues aside, I much prefer the interface of Mac OS or Linux desktops to Windows. Also, if nav software were developed for these platforms it's likely we'd get better designers and smarter programmers than the ones working in the Windows realm. I'm convinced Maptech's current developers do not even operate boats. Matt O. |

Investigate OS X on Mac -if money is no object- or Linux which is free. Both will run Skype software and neither will leave you feeling like you're walking around with your pants down around your ankles every time you log on. |
