As a 12-year veteran Sybase DBA and programmer, I doubt that I have the proper perspective to debate most of your points. However...
3. Table-level locking by default. This one just blows me away; Sybase didn't support row-level locking until somwhere around version 11, and table-level locking is still the default. If you're DBAs aren't on top of things, you'll have deadlocks all over the place. They still haven't enabled it for the system tables, so make doubly sure you don't do any long-running code that touches them, or you'll have deadlocks for sure.
Not quite. Page-level locking was always the default, where a page is 2k bytes (by default; up to 16k in current ASE.) This was never a really big problem for Sybase performance, except for applications with small very-active tables, but it always sent Oracle programmers into fits. So starting with ASE 11.x , alternative locking schemes are provided, including datapages-only locking (index pages are not locked) and row-level locking. Promotion of a page lock to the full table can happen if a significant fraction of the table is being altered in a transaction, however it's not very common.
Current versions of ASE allow the default locking scheme to be set on a database level, and the locking scheme on each table can be set independently.
On Pacifica Radio, I've heard the term "web maestro." I never realized why they did that until I read this discussion...
Of course, that raises the question: is it sufficient to just translate the terms "master" and "slave" to another language, which doesn't have the same semantic associations for politically-sensitive (and mostly foreign-language-ignorant) Americans?
However, even if it had gone into the right inclination for a station rendezvous, it still couldn't have made it to ISS with its very heavy payload on this mission. This was to have been the heaviest shuttle landing ever.
I swear... back in MY day, it took my buddies and me hours of backbreaking work with ropes and planks to make these. Nowadays any punk with a pirated copy of Photoshop can do it...
As a sysadmin at another major metropolitan newspaper website that has seen the "Slashdot effect" firsthand, I can tell you that it's just a blip on our logs. A few tens of thousands of page views, tops.
We see much more traffic when we get Drudged, and even that doesn't really stress our servers (no noticeable difference in response time).
Any major newspaper site is going to have way more than enough server capacity and bandwidth to handle front-page links from Slashdot, thank you very much. And almost all of us beefed up our spare capacity significantly after 9/11...

With or without your permission.
Perhaps by then someone will offer a service where you can pay your $600K to PREVENT everyone from getting your gene sequence...
I've tried the first one, it doesn't work. Of course, maybe I should have tried it more than a couple of miles away from JSC... local women just aren't impressed by that.
Unfortunately the STS has a rough time making it into the ISS' orbit because it doesn't get a easterly boost from the Earth's rotation because it is launching itself so steeply northward to hit the ISS.
Not true. It is no more difficult for STS to achieve the ISS's orbit from Canaveral than it is for Soyuz to achieve the same orbit from Baikonur. The easterly vector provided by Canaveral's latitude (1337 ft/s) is much less than the easterly vector required to insert the ISS orbit, and is thus helpful. In fact Baikonur (45.6 deg N) pays a significant penalty compared to Canaveral (28.5 deg N) in reaching that orbit. The problem is the additional northerly vector that's required. But launching into a high-inclination orbit always incurs a penalty compared to minimal-inclination orbit (equal to your latitude) -- so STS can't launch nearly as much into 51.6 deg as it can into 28.5 deg.
Yes, the 51.6 deg inclination was selected so that the Russians could launch to it from Baikonur, though another argument made for it is that it's better for earth observation.
One of the reasons Skylab was scrapped was its orbit was not very easy for the STS (then in develpement to be an adjuct system to a space station) to hit.
No. Skylab was scrapped because STS didn't get off the ground until 2 years after Skylab's ashes were scattered over Australia. NASA had plans to try to reboost Skylab on one of the earliest shuttle flights, but STS was delayed and simultaneously the predictions of atmospheric drag were incorrect due to high solar activity (which expanded the atmosphere.)
Now, Skylab wouldn't have been a walk in the park to use -- it wasn't really designed for on-orbit servicing and resupply -- but it could have been useful, if only to study the effects of long-term exposure to the space environment. It's true that its 50 degree inclination orbit would not have been as good for STS as 28.5.
Jim Oberg wrote an interesting article about the fate of Skylab... and yes, he says that the 50 degree inclination was a mark against Skylab, but not a fatal one.
Yes. And SQL has nothing to do with Verity. Verity is a full-text search engine, not a relational database management system. Verity's query language looks nothing like SQL.

Also probably would have resulted in demotion and reassignment for the navigator of the Enola Gay.

Are you sure you're not holding it backwards?
I suppose it goes without saying that this is for people who sleep alone.

Well, AFAIK the Wachowski brothers were "lesser known directors...who could use the exposure" before The Matrix. At least, I hadn't heard of them.
But maybe I live under a rock.

Just no appreciation for the craft anymore...
You mean James "Kibo" Perry?
...by the Internet of 2003?
Kind of like the unfrozen guy on South Park, who was from a time when the Internet was slow and hard to use (1996)...
Yeah but they'd need another 3 discs to list all the bugs they don't know about.

However, Anne Frank's diary was published posthumously, so the Nazis couldn't sue her for violating her NDA.

I believe the correct phrase is "hookers and blow."
And, of course, NOBODY ever posts to Slashdot from work.
Buy them and lay everyone off.

or, indeed, to capitalists...
One at a time, not all at once.
I think you're confusing "fantasy ISS" with what's going to be left when "Slasher" O'Keefe gets finished with it...
