Back in the early '80s (I graduated in 1982), my high school had accounts on an HP3000 at a regional educational serivce center. They had a room with four 300 baud acoustic modems and four DecWriter II printing terminals. The math department folks didn't let us see the deep documentation that let other high schools in the area 0wnz0r the HP-3000, but the password to the school's admin account was public knowledge. During this time I got my first modem, but I didn't want to dial the HP-3000 up because we had assigned phone numbers for each terminal, and I had more fun hacking on my TRS-80 anyhow.
Once I managed to write a chat program that used the message command, but the only time I seriously tried to use it, I couldn't get the guy on the other side to understand the concept of typing in his session ID instead of his logon ID.
This was also the machine on which I first discovered Crowther & Wood's Adventure. Somewhere in a box in storage I still have the printouts of my sessions on it.
Then the school got this stupid TI refrigerator-looking mini which crashed whenever someone turned off a terminal. But I never got to mess with that one.
have a local/etc/hosts file with all existing hosts.
Well, it worked for FidoNet. The FidoNet nodelist was esentially a huge/etc/hosts file with compressed diffs sent out once a week. Fortunately FidoNet started to shrink (due to the rise of the TCP/IP internet) just as the nodelist was starting to get really unmanageable.
Yep, either a Pismo (Firewire G3 Powerbook) or a current (they did finally speed-bump the FSB to 100MHz, right?) iBook is probably the best choice. Plus, it all he really wants to do is emacs, he should get the cheaper 400MHz Pismo, and find some way to leave "processor cycling" (lower CPU speed for better battery life) turned on all the time. If he's willing to run OS X (it's not Linux, but it's still some form of *nix), it should be easy to leave processor cycling turned on all the time for enhanced battery life. Add bash and a rootless X server and he may find himself not wanting to go back to Linux.
Actually, the Pismo has one advantage that even the PBG4 doesn't: you can install two batteries. Sure it's going to weigh a little more than the CD-ROM, but that's at least 8 hours of battery life with proper energy saving settings, which likely can't be beat by anything larger than a PDA. (But the batteries aren't cheap. The third-party PBG3 batteries at Fry's are $200 each.)
Plus, OS X can run MacOS 9 software, and with Virtual PC, Windows software too. (A WINE-like emulator would be better than Virtual PC, though.)
Yeah... uh huh.... admit you just like d/l'ing porn quickly to get your fix;-P
Porn is just so last decade. Besides, porn is mostly interchangable and can be had in nice small doses as.JPG/.PNG files that are possible to download with a modem. My drug of choice is anime (try mainlining some Excel Saga sometime), with little diversions into Red Dwarf/Enterprise/Reboot. Not only do I need moby NNTP bandwidth, I constantly need to keep burning CD-Rs to free up disk space.
It may not be available by FTP, but it will likely be available by NNTP, at least on servers that have good completion and no censorship of binaries groups. This is one series certain to show up on alt.binaries.multimedia, as the animated version of The Tick seems to have been a popular post in recent months. The only reason I never downloaded it myself is because I was getting too much other stuff already. That will have to wait until after I get a terabyte RAID or a DVD-R, if you know what I mean.
I use the oldest P2P file-sharing app of them all: alt.binaries.* in Usenet. Works great, as long as your news server doesn't flake out under the load of the September crowd "giving back" to the group by re-uploading something that's already been uploaded to death, and is already on DVD, too. (my main context here is alt.binaries.anime.)
My second favorite way is to go over to a friend's house and push files at his Hotline server over 100Mbit Ethernet.
Nice sound bite, but completely missing the point behind collecting MP3s vs streaming. The point is to have your own copy, rather than being at the mercy of someone who a) spoon-feeds to you what they want you to hear, and b) can, like the Ministry of Truth (Orwell's, not the band), declare any music that you want to hear as non-music and deny you access to it for all time.
Never forget the fable of the programmers and the ASCII pr0n. When an ASCII picture of a naked woman appeared on the mainframe, all the programmers printed out a copy, except one. He punched a deck of cards. Sure enough, the file was discovered by management and deleted. Then while the other programmers were stuck with their fading printouts, the one programmer still had his deck of cards and could print the naked woman any time he wanted to.
She obviously didn't know how to download stuff from Usenet. An ISP with a good feed and retention on alt.binaries.multimedia.* is enough to make DSL worth dropping cable TV for. And having a fixed IP so you can SSH back home is nice, too.
Especially since I didn't mention the other effect of blocking outbound port 80 SYN packets. "No pr0n surfing from the web server console! Now get back to work!" (And yes, I do frequent The Monastery, how did you know?)
Also, you shouldn't let your webserver send any outgoing packets unless they are originating from port 80.
If you're really paranoid, you also shouldn't let your web server send any outgoing SYN packets from port 80. This will help prevent web-exploit worms like Code Red and Nimda from spreading.
I'd love to see a plugin for apache that allowed a central server fingerprint database for new exploits.
Then we could couple it with my favorite idea for an Apache module: mod_labrea. This way any 'undesirable' HTTP exploit could be given a reverse DoS by keeping the connections alive and stalled for as long as possible.
As a bit of perspective, I used up about 1/3 mile (most of two 1000 foot boxes) of cat-5 wiring up my house. (eight six-wire bundles of cat-5, plus 300 feet more of RG-6) They used up fifteen times that. Of course it's a little easier to label the ends when you're only pulling six at a time.
Wow, there's nothing like a picture of a Cat-6500 switch full of ethernet. Except maybe a Cat-6500 full of gigabit fiber.
Those of you drooling to order one should keep in mind that this "Q" (ooh, shiny) will likely only play region 2 DVDs. And for you European folks, there's not even a guarantee that it'll play R2 PAL either.
Ooooooh, it's got a shiny 56k modem in it! Fsck me harder. No Ethernet, no chance. I'm tired of all these consumer electronics devices without even a simple cheap-ass 10 mbit Ethernet port. Maybe they don't want to deal with user interface issues of configuring it, but DHCP isn't exactly rocket science, and they could simply require DHCP. I don't need yet another damn modem to fight over my analog lines when I and many others have a perfectly decent LAN behind a NAT/DHCP box with a live internet connection.
Besides, running things over Ethernet means I can run protocol analyzers and proxies and such to help hack a device.:-)
Open source. Burn a copy of the source to libjpeg, and an ascii text copy of the JPEG spec to every CD-ROM if you're really paranoid. If you're truly paranoid, burn a one-bit-per-pixel.BMP of the spec with a prime number of pixels in each dimension.
I just thought of an interesting way to help insure the validity of digital photos.
First, you have the camera itself generate a pair of random prime numbers. Then have it generate an MD5 checksum of each image it takes, and digitally sign the MD5 checksum, including a copy of the public key in every signature for reference (and to make it more obvious if and when it changes).
Of course this is subject to the usual crypto problems such as finding an efficient prime factoring method or of tampering with the camera (either by loading a known key or extracting the existing key, which could be deterred by using tamper-proof hardware).
While it doesn't transfer the signature to legitimate edits of the picture such as cropping or re-compression, it would ensure the validity of the original file.
Ah, for the good old days when people had to copy books by hand, and the words were sacred. Now they can print millions of copies of any old junk, most of which gets thrown away. And they can change it any way they want when they print it, instead of the One True Copy chained to the bookshelf in the abbey library. Heaven forbid years from now when some archelogist digs up a Harlequin romance novel and the reader actually thinks the story was real.
You still can't edit a copy that has been burned to CD-R, except by destroying the CD-R itself.
What I see here is not a technology problem of digital vs analog, but an attitude problem of "save everything" vs "cull the best".
In the past it's been harder to cull because you would have to cut frames out of strips of negatives. And you couldn't seamlessly put the other frames back together into a single strip after you did it. And just as that discourages culling, it also seems that preview and instant review of digital photos encourages culling.
In the long run, as long as you take the same attitude about preserving "bad" pictures (and I'm not talking about out-of-focus or otherwise spoiled pictures, but the merely "uninteresting" ones), digital will win out because it's possible to losslessly copy them over and over on to the format-du-jour.
Since I still haven't taken enough digital pictures to fill up a CD-ROM yet, my idea is to keep at least two master copies on live file systems (one of which is my laptop), and simply record EVERY picture to a fresh CD-ROM every now and then. This can have the effect of spreading copies like seeds on the wind, especially if you stash your copies of your collection at various locations, like your parents' house, your cubicle at work (unless you like taking those kind of pictures, that is) etc. It doesn't take too many widely scattered copies of an entire photo collection to ensure that at least the older ones have sufficient redundancy to ensure their survival.

Small problem: how are you going to get the heat sink to fit with an adapter board between the CPU and the socket? I think you could actually increase the chance of frying your CPU because you'd have to have a more complicated (and therefore more failure-prone) heat sink mounting mechanism.
Yes, I do. Eventually, this site will have a whole section devoted to aspiring actors. My immediate advice is: study, study, study. Read the classic plays and see the great movies. And for the love of Bob, study!And read Backstage. Get yourself into some sort of acting program or workshop. Just avoid anything that tells you they'll give you a free book by L.Ron Hubbard. It's a scheme to recruit you into Scientology.

Wasn't that the trick behind figuring out the other important code the Germans had? The one which was basically a binary XOR with a key?
