Ooooo. So it'll be slightly faster than the spring melt in Greenland, eh? I have a real problem with languages that try to handle garbage collection for me. "Just let the object fall out of scope and the garbage collector will take care of it," they say; then when my application server is responding to hundreds of requests per minute and the free heap's rapidly diminishing stature signals the garbage collector...
Thanks, but I think I'll stick with an environment that lets me do the right thing and do it quickly.
Oh, and since when is stuffing all of your code into a single file a good idea? Hello? Sometimes 1 file per function makes a lot more sense. C# just sounds to me like a linguistic fashion show that was paid for by Microsoft.
The original question was about a datamart. For production databases, you are absolutely correct. For loading data in and out, however, RAID 5 is perfect.
How do you do that? This is offtopic, I know. But I've just installed ssh on my work servers and I've got it on my laptop. I'd love to be able to use X remotely, but I've no idea how to do it. Where should I go to find some instructions, particularly useful ones detailing what file(s) I need to edit (and what needs to be added/changed) and what program(s) (if any) I need to invoke?
I'm using Sybase ASE 11.9.2 as my company's database, and running it on Red Hat Linux 6.2. We've found that using raw partitions can work, but with this version of Sybase the largest you can get a partition is 2GB so you have to distribute your database across several devices. That's no big deal, though.
Now, if you wanna talk about performance...get yourself a RAID and use a multiprocessor system. Sybase understands SMP systems and the RAID will help you on your I/O.
You can absolutely do this. Now, depending on which version of Sybase ASE you use, you may run into some dumb limitations. For instance, version 11.9.2 has a 2GB limit for the size of a device, so you have to partition your disks into 2GB slices, and distribute your database across multiple devices. I think they increased the size in ASE 12, but I haven't worked with that yet so I don't know what the limit is there.
Stiffed seemed to me to be too little, too late. After reading The Myth of Male Power by Warren Farrell, Faludi's writing just didn't echo with me. I think she wrote about some aspects of "normal" masculinity that need examination, but I couldn't help feeling like she was ignoring some significant phenomena. In the end, although she did have some interesting insights, I found her book less interesting than irritating.
You know, that's a damn good question. I've got a PGP key pair, and I even use PGP to encrypt messages -- but it's a pain in the ass to fire up a text editor, compose the message, save it to ~sbeitzel/tmp/msgXX, encrypt it, then import the ASCII armored ciphertext into my email program. I'm using Linux on the computer from which I read & send email, and I really like having a multi-window mail tool. I like having a couple of composition windows open at the same time that I'm looking at my inbox.
So what can I use as an email client? elm and pine, however handy they are (pretty handy), only let me work on one thing at a time. And elm's PGP integration has left me underwhelmed. pine strikes me as elm, only with more screen clutter. Kmail, the last time I checked, sucked almost hard enough to turn a sheep into haggis. StarOffice and Netscape don't grok passwords with control characters in them (yeah, my passwords look like line noise). I've been using TkRat, which does decoding okay but doesn't do outgoing signatures or encryption at all well.
Lonely Lily was a Usenet spam that came out of some place in China (I think it was China -- maybe Taiwan or Hong Kong). The spam was for a porn site, and the sender spoofed it to look like it was sent from pobox.com. People did track it down to the real originating host and managed to cancel the articles.

Oh yeah. I remember the Green Card spam on Usenet. Wasn't that the one that inspired the CancelMoose? Then we had David Rhodes and his MMF. Then the Lonely Lily spam...
Usenet was so much better back in the 80's. And even then it was mostly crap.
So sorry, but unfortunately I must inform you that it is, in fact, my network of which I speak. I didn't claim to control the office network. I control my network. I have DSL coming in to my apartment, and I have a network here.
This fella sounds okay. Did he omit anything that some of the wonkier suggestions farther up the page might have put in? Okay, here ya go: "Open source GOOD! Censorware BAD!"
What's the matter with this interview? I think it's great that we get a story about a kid who's into a bit of hacking and is acting responsibly. Especially since it wasn't Katz who wrote it!
A few weeks ago I saw a comment from a lawyer who said, if I may paraphrase, "STFU, all you 'IANAL but..' idiots. I am a lawyer and here's the way it really works..."
Okay. I want to see the lawyers talking about this. I don't want bored sysadmins who read a few Nolo Press DIY law books; I want the guys who do this for a living. What do you think? What does this really mean? Is this just smoke-blowing, or should we all start funneling money into the MAPS legal defense fund?
Fine. Then don't subscribe to the MAPS RBL. If your upstream provider is doing so, then see if you can find another one who doesn't...and tell your current provider why you're leaving. It works for the Christian Coalition; if there are enough people who "think" like they do to do it, maybe you can find enough kindred souls to make a difference.
Personally, I think that the RBL is a good thing to have around. There are a lot of people who think that they can do whatever they want with electronic communications because it's their computer. Well, MAPS and the Usenet Death Penalty and subscribers all over the world, as well as individual users with their own filtering schemes are here to say that "your freedom to swing your fist stops at my nose". The spammers can do whatever they want...until their crap hits my network. Then I get to have some say about it. And that's a libertarian sentiment, too.
I was riding a late N-Judah train home some months ago, and a kid got on at the Embarcadero station. He looked kind of nervous and was carrying a rucksack with an SFO luggage tag on it. I asked him if he needed directions, and he turned out to be going almost as far out as I. So I told him where his stop was. He sat next to me and we talked a little.
After a few minutes of conversation (Where ya from, whatcha do...) he laughed and said, "I'm a hacker." I replied, "Yeah? What have you done?" He told me about some DoS stuff. I told him I wasn't all that impressed, that basically any system can be cracked, given time and ingenuity. I told him that what really impressed me was creative, constructive work. He then told me that he and a couple of buddies had gone into security consulting, setting up defenses against "hackers" like him. I told him that was a lot more impressive, that by contributing something real, by making people's lives better, he'd get real respect.
I don't know if what I said made any real difference -- certainly, he'd already started to walk away from script-kiddie stuff -- but I think that the search for recognition and respect was a significant factor in his life; I think that as he finds acknowledgement for constructive behavior, he's going to be less and less interested in k1dd13dom.
As you come into town from the airport, there's a big sign proclaiming that you are now entering the Silicon Valley of Mexico.
Guadalajara has a couple of high tech plants there (disk drives, I think -- I'm not entirely sure). When I was there in January, I was surprised by the Internet connectivity. Walking around town, there were Internet cafes and computer stores every couple of blocks.
You'll want to pick up some Spanish for living in Mexico, that's for sure. But most people in Guadalajara speak a little English -- they've got the university there, plus there's a community of about 2,000 American expatriates living on the outskirts of town. I found it a little frustrating since I wanted to practice my Spanish and everyone kept trying to talk to me in English.
Finally, the cost of good tequila is very low there, as the town of Tequila is only 60km away.
The people are very friendly, the cost of living is really low, and it's a major city so there's lots going on and the populace is used to foreigners. What more could you want? A tech job? They've got those, too!
I was basing my reply on conversations I've had with felons and the limitations they faced. I was unaware that these restrictions varied state by state.
they get bonus points... for being the enemy of our enemy
I have this saying: "The enemy of my enemy is occupied." Just because somebody's gonna beat up your oppressor doesn't mean you should give them ammo or cozy up next to 'em. Your first point is great: if they GPL it, then well and good. But I think it's wise to go slowly and be skeptical whenever a traditional corporation (do they get more traditional than Big Blue?) says, "Hey, I've got a deal for you!"
in VSS you have to lock the file before you can can change it
Not necessarily true. When the administrator sets up a VSS database (repository) s/he can enable multiple checkouts, so multiple developers can have concurrent modify access. When this happens then the conflict resolution is the same as in CVS: the second and subsequent checkins have to do a diff to resolve the possiblity of conflicts. The builtin diff tool is pretty cool, but it doesn't let you make decisions in situ. Still, I worked at a shop where there were 5 developers working on the same codebase and the automatic merging worked very well for us. Note that this works fine for things like C, where local changes tend to be locally scoped, but it is lousy for things like HTML or PostScript where local changes tend to have global scope.
I have used both systems, so I'll comment on my experiences. I haven't administered a CVS repository, so some of my knowledge will be incomplete there.
The migration process question is easy to answer: when you migrate, you're gonna lose all your history. So when you do, I recommend you burn a CD with your VSS repository on it and archive it on a server somewhere. Then, do a complete checkout of your source tree into a fresh location. From there, do a massive add to your CVS repository and boom, you've got your source migrated over. One thing you may want to do is write a script that will insert an $Id:$ tag in a comment up at the top of each of your source files before they get added; I find it awfully nice to have the revision number right there so that when somebody asks me what version I'm working on, I can tell 'em.
On the differences, an exhaustive list would be really long. You might take a look at the FAQ for comp.software.config-mgmt as a starting point. In brief, though, CVS has these advantages over VSS:
The repository doesn't automatically get corrupted by usage. (VSS does this.)
Checking in and out don't get exponentially slower as the repository gets big.
There are clients for just about any development platform -- so your Mac HTML/Graphics people don't have to have CodeWarrior and the VSS plugin in order to check in their work.
It's free
Actually, if you can afford the package, I'd suggest looking into Perforce. It's very similar to CVS (including the variety of platforms for which it has clients - although the Mac client is an MPW tool, which is great for programmers but icky for designer types), and it introduces a couple of very nice features: atomic changes (so when you check in a bunch of files, the commit doesn't happen until they're all in) and a really slick use of the filesystem so that with really huge repositories it's still lightning fast.
Sure you could use a laser. But forget about actually moving bits across the link whenever it rains or snows or there's a high pollen count or there's blowing dust or fog or...
No, they're not describing cookies. Cookies only get sent back from your browser to the issuing domain. So, for instance, your slashdot.org (or slashdot.com) cookie can't be read by cnn.com servers. The C|Net patent is talking about doing something similar to cookies, but doing it in such a way that the browser ID can be read across domains. I'd guess this is something they developed to handle the fact that they've got tens of domains (see other comments about news.com, download.com, etc.) and their marketing department surely wants to track user sessions across those different domains.

I paid $49 for my 2x LS-120 drive. That's not much more than the cost of a plain ol' 1.44MB diskette drive.
When was the last time you shopped 1.44 disk drives? The Chip Merchant will sell you a 1.44 drive for $12US plus shipping.
