I know you're joking, but what sort of fool would trust the seller with their own CC#?
Why does the card holder care? Your liability is limited to $50 by law, or zero by many card issuers. Merchants are the ones who lose with fraud, not the card holders or the credit card companies. In fact, the card company profits from fraud by hitting the merchant with a charge back fee in addition to reversing the transaction.
Imaging you have a huge medical database on several servers and are running out of disk space.

With Oracle you can use ASM to manage the raw devices while the database is running. Most real databases including Oracle and PostgreSQL allow you to manage tablespaces online.
And the reason you close the shower curtain after every shower is that it mildews if you don't.... so you either buy a new curtain every 6 months or you close it after you're done.
Walmart sells a commercial / hotel quality shower curtain for under $10. It comes in dark blue, forest green, cream, etc. Ugly, perhaps, but I've had them for years and as the package claims, they never mildew.
I agree with you in general, but isn't it just as easy to ensure data integrity via application logic as it is via triggers and stored procedures?
No. Database constraints ensure data integrity. Application checks can only hope to get it right. Suppose you have a table:
CREATE TABLE foo (x int NOT NULL CHECK (x BETWEEN 1 AND 5));
With that constraint in place, you guaranteed the column contains 1-5. Even if your application is small, you may update that table in multiple places. Are your checks correct in all of those places? What if the constraint needs to change later? What if someone runs some SQL manually and accidentally uses the wrong value?
But, it is an inescapable fact that an incredible amount of porn is sold on DVDs each year, and, it rivals the Hollywood system in terms of volume and moneys involved.
Can you substantiate that statement? The article for this story claims the opposite.
(This might in itself be a stupid example, but this(That mysql will commit, even if the transaction contains error) is a real problem, when doing developing using java/php))
This behavior is perfectly valid. Oracle does the same thing. This is a feature: you, the user, can choose to ROLLBACK or continue on error. Would you want a typo to abort a transaction during interactive use?
SQL> CREATE TABLE t (id int NOT NULL UNIQUE); Table created.
SQL> SET AUTOCOMMIT OFF

How exactly do you as the hosting provider handle such a thing? I believe GoDaddy did the right thing to a point.
GoDaddy was the domain registrar, not the hosting provider. There is a big difference. I would never use GoDaddy or any other domain registrar that would alter a registration without a court order.
I estimate that a 42U rack can fit 240 drives. By the end of this year, that means that a company will fit 240TB in 4.75 cu ft.
With the Sun Fire X4500, a 4U server that holds 24 drives, your estimate is exactly right. However, even with 1TB drives, you have to account for redundancy and other overhead (such as database indexes), so the total usable space is probably less than half that. Fitting a 100TB data warehouse into one rack seems feasible in the near future.
Storage services such as Amazon's S3 makes this very cheap and easy.
When we turned it off, guess what? It turned itself back on. Of course, we had no explicit record to demonstrate this to google, and they had no records of their own. It cost us several thousand dollars in fees to google.
Google tracks all changes made to your account. See Campaign Management -> Tools -> My Change History. I just changed a test campaign from content network to Google search only and it shows in the history:
I know that I don't fully trust AdSense.... It was obvious someone was clicking just to get their sites money from AdWords... I payed what was owed and cancelled all my campaigns, and haven't been back since.
AdWords is for advertisers, AdSense is for webmasters. As an advertiser, you have the option of only paying for Google search traffic (plus optionally partner search like AOL). If you don't like AdSense traffic at all, disable it for your campaigns. AdWords now allows you to block poor converting AdSense domains through the web interface.

Where can I find lists of DNS servers I can use instead of my cablemodem's default from my ISP?
OpenDNS
Maybe because you can simply tie the session to the client IP adress and verify it during each request, which puts an end to the hijacking.
Not with NAT, which is typically when you are most vulnerable (i.e. a shared wireless network).

I have been to several gas stations at which for whatever reason mid-grade/plus was the same as or slightly less than regular.
In Iowa, the mid-grade is mixed with Ethanol, so it is cheaper than the pure gasoline options.
Better long-term would be for people to stop using compilers for user-space applications and write everything in interpreted languages (à la OLPC).
How do you install new libraries / modules / packages for these interpreted languages?

with the other big players being ... AOL
AOL uses Google for search.
Three requires you to realise that the numbers are unique, within a finite range, and you have sufficient *bits* for a radix sort.
If the numbers are unique, you don't need to sort at all. Use a bit vector to store them and print in order.

If you do a spotlight search from the menu bar, items in the drop down list cannot be dragged and dropped or have their path shown.
Hold the mouse over a result item for a second to display a tooltip with the name and path.

The problem is that it also happens under non-interactive use such as from php/java and there it's a real problem..
Is there some reason you can't check the return value / catch the exception and decide how to handle the failure?
This behavior is perfectly valid. Oracle does the same thing. This is a feature: you, the user, can choose to ROLLBACK or continue on error. Would you want a typo to abort a transaction during interactive use?
But to install the Oracle *client* , I need to download 3 ISOs, install Xwindows on the server, tunnel Xwindows over SSH.
Installing the Instant Client involves merely unzipping a file.
Postgres is fully ACID compliant
As is MySQL.
has mature support for just about everything
It lacks anlaytic functions.

Personally, I use directNIC and Domain Contender.

No one trusts automatic C++ code generators. So why do we trust automatic SQL code generators?
We don't. That's why we have explain plans and hints.

No matter how much RAM you have, Windows still seems to need a swap file that is constantly being written to
Nice FUD. You can disable the pagefile in Windows XP.
Add to mean "close the matching element".
You mean like Lisp S-expressions?
Adobe, Google, and Microsoft all use Perforce as their primary source code management solution.
Amazon does too.
