Here are some really useful utilities to help design wireless networks and to help plot their approximate coverage areas:

Microwave Radio Path Analysis Generates a terrain profile graph and obstruction report for a microwave radio link between two points

Wireless Network Link Analysis Calculates approximate received power level and fade margins for microwave wireless links

Longley-Rice Path Loss Analysis Generates a image showing the estimated Longley-Rice path loss for a given transmitter location

Installing Tomcat on Debian/Sarge in some steps:

1. Go to José Fonseca's homepage and add his repository to sources like he says.
2. apt-get install j2re1.4 j2sdk1.4 (I have no idea whether or not you need the sdk).
3. apt-get install tomcat4 tomcat4-webapps
4. Go into /etc/default/tomcat4 and set JAVA_HOME="/usr/lib/j2se/1.4".
5. Probably do /etc/init.d/tomcat4 restart
6. Point a web browser at http://wherever:8180/
7. Muse on bytecode languages, administration overhead and whether or not they are necessary if we assume the OS actually works.

Goodbye harddrive! The console system I've set up has an *old* harddrive with which I've installed a basic linux system that automounts a network share containing my roms. Plays games well, but the hard drive is dying.

I'm in the process of tearing apart a KnoppixMAME iso as I type - add a script to run after boot and I can finally use the magnet from the old hard drive to cause my BOFH boss to have a really bad day!!! MUAHAHAHA.

I run a mailserver on a dynamic IP (cable modem) with my own domain name. For inbound mail you just need a dynamic DNS service. Lots of large companies block email listed as coming from dialups and cable modems, but relaying your mail through your ISP's smart host is one line in sendmail. Overall, I've found that ISPs are fairly competent if you read their guidelines carefully and are willing to get through voice mail hell when you need something.

bowling for colombine... and bazookas
originally aired nov. 10 2002

there's a good chance that you're one of the people who told - nay, exhorted - me to see this movie. well, i saw it. you can stop nagging now.

i'm not going to discuss bowling for columbine. you've seen it. i've seen it. any review would be little more than intra-referential. instead, i'm going to present a simple plan i've had for some time now. it's called the "bazooka plan"

guns. the good
there's a lot of talk about the "legitimate" uses of firearms: hunting, target shooting &c... all namby-pamby bullshit apalogia. guns are weapons. they're instruments of force and coercion.

now, it's no secret that force is the ultimate source of de facto authority. should the state wish to fine you for, say, traffic violations, they send you a ticket. if you refuse to pay, they send you a summons. if you refuse to appear they send some thugs to get you. if you resist, they attempt to subdue. if you will not be subdued, they apply force - the club initially, the gun ultimately. the fact that we mostly just jot off a cheque for that traffic ticket is a sign that we invest our state with de jure authority. we believe they have justification in sanctioning us, so we go along. if that de jure authority loses its support, however, the state is more than willing to exert it's de facto authority: force. violence and coercion are the gold standard of the currency of authority. mostly we never cash in our fiat currency for gold, but we know that fort knox is full of the stuff... just like we know that cop dinging us for the illegal left is packing a glock.

if a state is to have more than the appearance of citizen control (what we in the west refer to, oddly, as "freedom"), it is necessary that that gold standard be controlled at least in part by the citizenry. authority is only de jure if those who submit to it have the capacity and ability to judge its justness and act accordingly. if the means of coercion are completely controlled by the state, state authority can only be judged as de facto in nature.

this isn't a new idea. those patriarchal, slave-holding early americans knew it. when the second amendment talks about the right to bear arms being "necessary for the security of a free state" they're not talking about the security of the state, but the security of the freedom of that state. mao, put it better with his oft-misunderstood statement that "political power flows from the barrel of a gun." note that, contrary to nra propaganda, mao actually armed the population in the early fifties. he passed out free rifles. obviously mr. zedong was confident in the legitimacy of his party's rule. an armed populace is a voluntarily governed populace.

the capacity for revolution is a necessary prerequisite for the legitimacy of governance. guns good.

guns. the bad
bowling for columbine covers this section quite nicely. the culture of glorified violence, machismo, revenge, power and the worship of instant, pocket-sized and portable de facto authority over fellow citizens has made the arming of the american population an absolute and abject failure.

the part of bowling... that drove this home most succinctly (for me at least), was the interview with the michigan militia. i'm on record all over the place as dismissing the militia movement as being nothing more than a motley and poorly-dressed gaggle of right-wing nuts with zero und

As someone else mentioned, you'll need to forward at least ports 6881 to 6889 (or 6999 if you feel the need) from your router to your PC. Each window you open needs its own port.

You may also need to figure out how to get through your firewall, if you have one.

This site might prove helpful, if it is up.

Regarding your question: BitTorrent does work through routers even if your ports are "closed", but in order for you to download anything, someone else's ports must be open. You are uploading at such a high rate because someone else has their ports open.

If everyone's ports are closed, no one will be able to connect to each other and nothing will happen. If the seeder's ports are open and all of the leecher's ports are closed, the leechers will not share with each other and you'll be back to having a very slow FTP site (basically).

If you open your ports, you will see drastically higher speeds. You may also want to limit your uploads a bit since you need some upload bandwidth to be able to download. Your PC needs to be able to tell the other peers that it got the pieces that they sent.

HTH.

I don't know that I agree with the statement that spammers are stupid - some of their tricks can be quite clever - but it is one of the recognized laws of spam, formulated by the inhabitants of news.admin.net-abuse.email on the basis of their experiences dealing with spam and spammers.

It may be redundant - if it is, just moderate it as such, but here is a Torrent, so that we don't completely destroy the nice BiggestPOS' mirror.
I'll seed it for an hour or so.

OK, the video was stupid, but here is a torrent. I won't be seeding for a long time, though, so get downloading, and seed for a bit!

The actual firewall backend - ipfw, inbuilt and inherited from FreeBSD - is sufficiently sophisticated to enable per interface rules, but to access this functionality you need to completely disable the GUI firewall front-end and configure ipfw yourself using the command line.

Actually, it's slightly simpler than this. You can add rules via the command line interface or via other tools and the Apple firewall config panel simply becomes non-functional with a note added that other firewall software is in use. IOW: no need to explicitly turn the Apple GUI off.

You could have at least shown the imagination required to remove the bit about the "tiny webserver" at the beginning.

You have much to learn, grasshopper.

It's a cartoon.... On TV... On FOX, even...

It's been 15 years. What did you expect, really?

Besides, what else on TV these days is even close to the Simpsons?

Next, people are going to start saying the new Star Wars Series sucks because they're aimed at kids.

Oh, Wait...

Don't you people have any books to read or something?

"Worst Article discussion... Ev-ar!"

Not well documented, but to people who want to "roll their own" knoppix-type CD, there are plenty tutorials out there. Probably one of the more useful steps in remastering your knoppix is using what is unoffically known as a "kicklist"; a file simply listing all the packages you don't want. Then you can issue apt-get remove `cat kicklist` and poof, a great deal of the knoppix cruft removed in a flash. after that it's probably a good idea to run apt-get remove `deborphan` or something like that to further remove cruft.

Now for the interesting part of this story. I learned this because I too am new to debian. Started working with the userlinux project a while back because I thought it was something it most definitely isn't, so I decided to give debian a try. Fell in love quickly. It's really nice to have virtually any piece of software you want at your fingertips, and I feel they've done a great job at this. But having such a user-friendly software installation system, with such a rediculus installer is contradicting. Could *NOT* get the previous installers to work at all, never detected my network card, so I had to swim through modprobe and the like, trying to remember which module was the driver to my network card. After a few days of attempts.. I gave up, returned to redhat and read up on the many other ways to get debian.

Knoppix fell into my lap through discussion... well everywhere. I knew it was linux, but I figured it was Redhat based, since everything this day and age is. WRONG. So I did an HD install and experimented. Removing packages was a bitch for a long time, so much cruft I absolutely didn't want. One of the hardest parts I found was removing KDE *zips on flame retardant body suit*. Finally, after trying a great deal, I thought of just removing everything QT related: apt-get remove `apt-cache pkglist | grep qt*`, and this seemed to do the trick every time.

Long story short, knoppix is a great distro, but I'd love it more if there were a "knoppix lite", which only installed the base system, and absolutely nothing more, allowing users the choice of building an entirely new system on top of it.

*one last note: if you're having trouble removing nedit from knoppix, upgrade to the newest one from unstable, and then uninstall it... works every time.*

ALE is an open source tool that does this nicely. It is normally intended for turning a large number of images of the same thing into one higher quality image, but when you use the --follow and --extend flags. it can turn a sequence of images from a video into a single larger image.

To quote from their site: ALE is a free software program that renders high-fidelity images of real scenes by aligning and combining many similar images from a camera or scanner. The correct similarity between images is roughly that achieved by a somewhat unsteady hand holding a camera.

You should check out ALE then.

Nearly identical? Nope, not to the millions of victims of neurodegenerative disorders who Bush is robbing of a cure with his fundamentalist stance on stem cell research. Not to the millions of elderly who depend on Social Security and Medicare benefits, which will have to be drastically cut thanks to Bush's happy-go-lucky attitude towards the gigantic budget deficit.

Look, real life is about compromise. For better or for worse, we live under a two-party system, just as Americans before us have for close to 250 years. Voting for Nader isn't going to change our system--it'll just make the fringe he represents look even more extremist and out of touch with the needs of everyday Americans.

First off, the handwriting recognition is fabulous. And the assistant is just too cool for words. Write "lunch next Wednesday with Connie" and it'll ask you to pick which Connie is in your address book if there's more than one, then schedule an appointment next Wednesday from noon to 1pm with her. Make a long to-do list of things like "Call Jim". As you're going through your list ticking things off, highlight "Call Jim" and activate the Assistant, which will ask which Jim you want to call from your address book and dial the number through the built-in speaker or PCMCIA modem card, then pull up a call log app with call timer and notepad. Speech synthesis. Audio recording and playback. I've got my Newt MP2100 synced to OS X's iCal and Address Book already. (My wife has her's synced to Outlook at work.) I can connect it into any network (via ethernet or WiFi) and print directly to any networked printer, surf the net, or send an email. I can swap the network card for a modem card and fax or dial in to an ISP. The only problem with the Newton is its size: too big when you're not using it but just right when you are. I have a Palm Vx that I carry with me so I have quick access to phone numbers and (most importantly) my checkbook. But if it wasn't for the checkbook software, I would have ditched the Palm completely in favor of the Newt.

If anyone out there is looking for the best in PDAs, look into getting a MP2100 off eBay... they're only about $100. Once you add a WiFi card, ethernet card, modem card, large-capacity storage card, and a couple pieces of shareware, you'll spend about $250 total, and you'll never regret it. Matter of fact, you'll be wondering why the Newt -- which the last model, the MessagePad 2100, came out in 1997 -- can do so many things that Palms and PocketPCs can't, even today.

FWIW the Newton community is very active and passionate, and there's a lot of support for OS X and iApps, as well as loads of software. Oh, and if you want developer tools, there's plenty to pick from.

True, it's not easy being green. But after using both a Palm Vx and a Newton MessagePad 2100, while it's a bigger thing to cary around, there's no comparison... the Newton rocks.
