Correct you can set it to maximum reliability mode which ensures the the redo logs are written to all sites as the transactions are performed and before they are committed. This can be a big performance killer as you are adding network round trips.
It can also save quite a bit of IO.
Assume all fields are 1 byte, now say you have a table called person which has many to one relationships to 10 other tables. Each of those 10 tables has ten fields. Fully normalized this table is 11 bytes per row. Fully denormalized it is 101 per row. For any query that needs to read more than a small subset of the data (so that an index is not the most efficient path) this means roughly 10 times the IO cost. Even for queries that are more efficient with an index, you still have a large increase in IO because you have less chance that the rows needed will be in the same blocks. Also consider that you might be able to get by without some indexes that you might otherwise need. This frees up the memory used to cache that index for caching other data which could result in a better performing system overall. Throw in the performance impact of the integrity constraints or cascading updates for the denormalized table and you can really end up with terrible performance. It is a more complicated issue than it seems on the surface.
Yes they are. I think it has to do with the influence from all the binary devices they interact with causing them to never develop more than two shades.
I'm 27 and I must be somewhere in the middle because I don't seem to have enough shades to grok the use of the word "preciously" in your post.
It was stolen by white robots and subsequently lost, falling into the slipstream and eventually landing in England where it was used as a cricket trophy for some years before being recovered.
Scary, this is exactly what I would have posted, with the possible exception of the example. There were just so many horrid bugs to work around. I actually heard my boss make the comment that programmers are only worth a third of the time they bill for. I corrected her saying that we were only worth a quarter of the time we billed for and the joy of having an app done in access was worth the other three quarters.
I think my most annoying bug in terms of shear stupidity was "if (bVar)" as apposed to "if (bVar = True)" causing access to go into a tight little loop doing nothing but minimizing the window. Of course this did not happen when debugging.
However, that said, you've just pointed out a situation where your set of hydrodymanics equations fail to fully describe reality.
Nice subtle jab there.
I've seen a few. I was certainly less civil after the DMCA passed.
More seriously, how can you be sure. Any number of the insane things going on this day could spiral into us wiping each other out.
You don't need a fancy computer program to tell this is a forgery. The originals use of bold strokes to emphasize importance is completely missing in the copy.
No, win2k is much too recent. What you need to do is get a version of windows that is old enough to no longer be targetted. You still want something with a fairly comprehensive feature set, so I'd recommend Windows ME.
This may happen sooner than you think. My girlfriend is participating in a limitted beta of a service that does just that. I was watching her yesterday and it kept returning just one result - a sound clip of a cat being tortured. Seems pretty accurate to me.
If you are running a commercial linux then those command line tools provided by the vendor will be supported by them. I've worked for a company where I was able to use awk, but not gawk, because of the support issue

Any relation to Required technologies? Unfortunately, that's what I think of when I hear about a column store

yes, it has been a very frustrating week

Yes, lesser magnetic fields appear to cause brain damage and powerful ones can cause some permanent skin problems.
Cue the spaceballs references ...

Isn't that the spinoff of Cat-Dog where poor Dog has a much rougher go of it?
Nothing says "Good Italian food" to script kiddies like 133758

Gonna be tough to drive. Unless you get Scotty to come back in time and whip up a batch of transparent aluminum foil.
No, no, I'll call Guinness. I have the world's heaviest 20lb sack of barley. You call Smirnoff. Salut

If the stations are 1 mile apart then the maximum hike is 1/2 mile.
I gotta wonder, is that twice as expensive per mile or half
You must be the guy that writes my specs. Please go home, thanks.
check out Theseus Logic. They have a process using m-of-n gates with hysteresis which works with existing (or slightly modified ) vhdl tools.
ever recorded in recent history
I've always loved this phrase, at least since I first heard it yesterday.

With the amount of sugar we use, you could use earl gray or cow patties and nobody would know the difference
