Log Message: ----------- Make use of plancache module for SPI plans. In particular, since plpgsql uses SPI plans, this finally fixes the ancient gotcha that you can't drop and recreate a temp table used by a plpgsql function.
/etc/localtime isn't a symlink because/usr doesn't have
to be on the root filesystem, and thus a symlink
to/usr/share/zoneinfo wouldn't work too well when/usr isn't mounted.
The agent (which is running on your machine) asks for confirmation, not
ssh. Your passphrase and private keys should never leave
your machine when using an agent.
PostgreSQL ignored invalid UTF-8 sequences, meaning a ' character at the end of a incomplete sequence could cause only one ' to be seen by the parser when escaped. See http://www.postgresql.org/docs/techdocs.50 for the details.
And I would guess that the user's
private key is stored on said machine, as well. I don't know that public key
authentication does much in a local context.
The user's private key doesn't have to be on the sudo machine. Something like
ssh-agent could be used, where the user only types their passphrase on their
local machine (or uses a fancy authentication keycard), and sudo could then ask
the agent to sign some random blob of data, verifying that the user has the
correct key.
This wouldn't be too much extra work if users are already used to using
public key authentication for regular logins.
It's important to remember that you don't have to use passwords with sudo when
PAM support is compiled in. You can have sudo use other authentication methods,
including public key authentication.
Try a text-adventure game, such as one of the classic Infocom games or
one of the many text games that others have made since then. That will
exercise the important skills of reading, typing, and the imagination,
and will be pretty fun too.
It is interesting that these rovers have exceeded all initial
expectations. Every once in a while, something happens to one of the
rovers that people say will make it unusable, and the rover has
overcome whatever problem occurred and continue onward.
I wonder how much of this is just because of good engineering by all
the people involved in making the rovers, and how much of it is just
plain luck.
Eventually of course, something will happen to make a rover unusable,
but it is interesting that the rovers have lasted this long.
No, both symbolic links and hard links are filesystem-level under Unix. A hard
link is just an extra directory entry pointing to the same underlying file,
and thus cannot cross a filesystem boundary, while a symbolic link is stored
as a string and can contain any pathname (vaild or not.)
For symbolic links, you are correct that an application may need to be modified when it wants
to remove the underlying file instead of the symbolic link itself. With hard
links, the file will be removed when there are no more directory
entries pointing to the file.
With that approach, wouldn't you have to solve the problem of what to do when
someone is playing and their purchased number of hours run out? Just disconnect
them, possibly during an amazing adventure with a bunch of friends that took
longer than expected?

What's old is new again, eh? That is what MUDs have been doing for years and years (and MUDs are what everyone called "online gaming" for a long time)
/etc/localtime isn't a symlink because /usr doesn't have

to /usr/share/zoneinfo wouldn't work too well when /usr isn't mounted.
Probably because the standard libc functions don't allow for multiple timezones to be queried easily.
You might want to try SETEDIT or RHIDE. SETEDIT is an editor and RHIDE is an IDE, both written using the Turbo Vision toolkit.
True for reiserfs, but XFS only logs metadata to the journal. ext3 also only logs metadata with the default options.
The filesystem doesn't matter, of course, when using shred on the entire drive.

lynx is a good choice for many sites too :)

Perhaps you are thinking of the ANALYZE command (which can be done as part of VACUUM), which updates the optimizer's statistics for a table?
This may not work too well, since the rootkit may be able to detect and prevent the flash utility from working properly

And many of the sites using the new TLDs appear to be spam or scam sites anyway.

Why don't you just use a 32-bit compiled browser/mail program instead of switching computers?
If VMWare could virtualize the processor perfectly, then you wouldn't have to tell it what OS you're going to run, right?
What about starting kids (and maybe adults too) on interactive fiction?

Something like this might be a good start.
The evil attacker would just then load up all the IP address blocks owned by Google into the redirect script and use that instead of the User-Agent.
