They [Microsoft] developed some pretty incredible functionality into things like SFU 3.5 (which I just got for free with a systems magazine). [emphasis mine]
Er. I think not.
SFU is a bunch of half-arsed stuff cobbled together from existing licensed products, some of which could be replaced by better Free Software (such as Cygwin).
It's designed to cater to legacy Unix environments -- sites still stuck with NIS, NFS, telnet etc. -- not modern Linux/*BSD environments.
A proper, non-legacy "services for Unix" package would include Cygwin, OpenSSH, encrypted Samba access, CUPS support etc., and it would have the unfortunate but amusing effect of driving the customer away from Windows, not the opposite.
I am guessing you don't live in Europe. I am constantly amused by Americans who think Europe is this backwater continent which is not quite up to date with respect to the rest of the world. It may have been true 50 years old. It's no longer the case.

What exactly does "taking a slice" of a result set mean?
I suspect the poster is talking about linear slicing at the row level; in PostgreSQL, for example, you can do select... where... limit 25 offset 50 to get rows 50-74 of a result set. MySQL has a similar syntax. Oracle supports a size limiting clause, but I don't remember if it has a way to specify the starting offset.
There is no way to help the fearful. Unabated fear of disease or malformation is sort of a narcisistic thing; makes them feel special and the constant complaining is how they gather more attention to themselves than they would normally justify.
That may be true about some people, but certainly not about all cases.
As a sometime hypochondriac, the last thing I want to do is confide in anyone about my fear; I don't derive any pleasure, destructive or otherwise, from fearing that there's something wrong with me or from complaining and extracting sympathy from friends or strangers. I just want the damn fear to go away so I can go on with my life.
Certainly there's something abnormal about my mind since I so easily latch on to and get compulsive about imaginary diseases. Most of all, I think, it is the fear of being ill, of being permanent debilitated, and the social stigmatization and damaged pride that follows.
The only cure is diagnosis; rational, scientific information that will either dispel my fears or confirm them. To this end, searching for medical information on the net is, I have found, harmful to my psyche, precisely as pointed out by the linked article: the information is all too often vague, generic, contextless.

If you're looking for something refreshing, try Tim Powers (The Anubis Gates, On Stranger Tides, Last Call, Expiration Date, The Drawing of the Dark, Declare, others).
I can't praise Powers enough. And yet, the usual scifi/fantasy geeks here on Slashdot and elsewhere, the kind who devours Gaiman, Stephenson, Heinlein, Adams etc., don't seem to be aware of Powers. Are his books hard to find? Badly marketed? Not cool enough?
If anyone can do the disturbing, visceral, gothic and above all surreal magical realism, it is Powers. Gaiman is a good, inventive author. Occasionally in American Gods there are brief flashes of storytelling where situations cohere into solid, memorable set pieces. In Powers' books, the prose feels like magic, like some decisive, pivotal junction of history, on every single page. The characters really stand out, and the narration really reaches for your senses.
The book I would start with is The Anubis Gates, a story superficially about a present-day literature professor who becomes stuck in Victorian-times London. It also involves Egyptian magicians. And time portals. And a cloned Lord Byron. And some business with a huge ape on a rampage. And a guy who switches bodies. And a seriously zonked-out Samuel Taylor Coleridge.
Other relevant names for those who like Gaiman are James P. Blaylock, John Crowley (I particularly like his early The Deep, a strange and fascinating pseudo-fantasy novel) and Jonathan Carroll (just avoid White Apples).
You can't install global (as opposed to profile) extensions in Mozilla Firebird, as/usr/lib/mozilla-firebird and/var/lib/mozilla-firebird modification requires root access. You can change the owner on the directories and files, but that's hardly the right way. Firebird extensions tend to install themselves into the system directory, not the profile.
The folder tree view is broken. Really. It doesn't sync with the file pane. You can't right-click on a folder in the tree to perform actions on it. You can't drag folders around. The only interactivity allowed is on the open/close arrows.
I don't like KDE much, but I do envy KDE users for having Konqueror. It's a great file manager.
TheKompany's Rekall is supposed to be something of a "Microsoft Access for Linux". In other words, GUI-driven database application development: schema, forms, reports, scripting, etc.
Reuters Messaging. Specifically designed for the corporate user, with encryption, logging, resilience, etc etc.
From what I can tell, it's just a rebranded version of MSN Messenger. Same shit, different wrapping.

I second the Jabber recommendation. "Homegrown" is a strange term to use for this technology, as there are many implementations, including mature, commercial products.
My only problem with Jabber is the lack of a good MacOS X client. The only mature client, Psi -- which I use on Windows -- is a Qt app hastily ported to MacOS, and so it neither looks nor behaves like a native app. Not a big problem for me, personally, but my colleagues refuse to go near it.
He denies all claims of wrongdoing and suggests that if the pieces of code are the same, perhaps they were leaked from Kiss Technology and were then used by the Mplayer group.
This is an interesting problem that will require a solution. Can the Mplayer people prove that their code existed before it existed in Kiss' source tree? Certainly the contents of version control systems could be compared, and release repositories such as SourceForge could be used as evidence, but a more formal system is probably needed.
I imagine a system similar to copyright registration and escrow services, where a neutral third party would receive code checkins/snapshots that would be time-stamped, "sealed" as evidence (and compared against SCO sources, natch). Then the owner would stand on more solid ground, and even unpaid open-source developers would have a chance to protect their work. Of course, such a service would have to be highly affordable, perhaps even free, SourceForge-style; in fact, this is something SourceForge ought to support and promote.
Funny I was thought the same thing, but that wasn't in the post at all. My original post was mostly about how weird of a question, if it even is a question, this posting was.
I don't think it's a weird question. A lazy and ill-formulated question, to be sure, but not weird.
For my current project I will need to apply a caching reverse proxy myself, just so I can support the expected traffic.
The "10-30 users" metric is useless without knowing the output of the web server. If the web server is able to sustain an output of hundreds of pages per second, you don't need a caching web server.
He said users 10-30 users not requests, stop changing the posts meaning. 10 - 30 users on any site is nothing. Think those ten users hit refresh every goddamn second of their lives to fill 300 KB/sec of bandwidth?
How does he know there are 10-30 users doing nothing? He doesn't. You don't. Nobody knows. It's a nonsensical metric.
To illustrate, I could tell you my web server got a million users per second, only they weren't doing anything. See how meaningless this is as a statistic? You can only realistically track the number of page views.
10-30 users per second means 10-30 users are at any time accessing the site. And accessing the site involves downloading a document or other page-related asset, not just sitting there doing nothing.
Translating this into 10-30 requests per second gives you a useful lower bound. Graphics and other assets such as CSS further add to the numbers, but I was making a point.
If your web server can't handle 10-30 users, a cache isn't going to help much.
Depends on what the "web server" is; it might be expensive SQL stuff, for example. Or it might be a heavy-weight CMS thing; Plone's default skin gives me less than 10 hits/sec on a very fast SMP box, and the lack of speed is, amazingly, mostly in the templating system. This is a case where caching would help.
10-30 concurrent users I interpret as meaning 10-30 requests per second. To put it in perspective: 10 req/s is 864,000 req/day. 30 req/s is 2,592,000 req/day. If every page in your system is 30 KB in size, then 10 req/s is equivalent to a constant bandwidth usage of 300 KB/s.
Squid is a very good, well-designed, highly configurable proxy server implementation. I have not gauged its performance against other implementations, but performance, at least on Linux, seems entirely reasonable. It is popularly used to cache Zope sites.
Being a relatively ancient open-source Unix program, it adheres religiously to standards, and will correctly use headers such as Expires and Cache-Control to maintain cache coherence; Squid will correctly cache anything with a Last-Modified header.
Additionally, it supports upstream commands allowing your web server to tell Squid to invalidate cache records when content changes; you can implement this easily in server-side languages such as PHP, Java or Python (Zope's caching machinery supports this transparently).
I second the H.323 recommendation. On Windows you can use NetMeeting or OpenPhone. On Mac OS X you can use ohphoneX.
This being a standard protocol, these apps will communicate with each other. However, H.323 relies on UDP communication, which is always a problem with routers. Many routers (such as the 3Com OfficeConnect broadband router) come with built-in "NetMeeting support", ie. H.323 support.
But the nagging, unanswered question I have is this: isn't "I am become death" ungrammatical or am I missing some fine point. I can understand "I am death" (present tense) or "I have become death" (past perfect? -- I am not up on grammer), but I always thought "I am become death" was the result of some mistranslation on the order of "all your base."
It's just an archaic, poetic way of saying things. The Bible is a good example: "I am become a stranger unto my brethren, and an alien unto my mother's children" (Psalms 69:8, which later goes: "My time is not yet come", another antiquated phrasing).
The download pages do not work with Mozilla Firebird 0.7 -- I get the 404 after going to the pages and asking to download. It works fine with IE, so they're obviously checking the User-Agent header. Stupid, stupid admin (or is it AOL exec?) creatures!
I haven't read the "Third Manifesto" book, only skimmed through it at the book store, and my impression is that it's not relevant for a database course.
There's algebra, and then there's math. Relational theory is about the algebra, database systems are about math across different domains, using that algebra.
That doesn't make sense. Algebra is math -- it's a branch of mathematics. Database applications implement the relational model.
