@gnat One more VTD and it's gone.

Hi there, I wanted to know if Microsoft offers any online certification for MSCD as in the exam being done online and since I don't know where to ask this I thought that you guys could perhaps point me on the right direction at least ;)

Hi there, I wanted to know if there are cases where escaping is better than prepared statements since I don't know where to ask this I thought that you guys could point me in the right direction at least ;)

Lambda the Ultimate - Programming Languages Weblog: Howard on Curry-Howard

@Shahar unless you're using ancient version of whatever language that doesn't have a method for prepared statement I can't think of any reason not to use it. You get more safety doing so, and can avoid internal and external inserts from being compromised

@Guapo nice name. They are both equally secure (Shahar (TM) certified), so now the question is which one is more efficient and when.

@Shahar I think that depends on a lot of things aside from the queries itself which do play a big role, but also how fast is that query accessed over and over, are you caching, and several other points would play into it. In the end I think there will be very few cases where you could gain from a millisecond to a second on speed at best

@Shahar not a very good example as there are other things within the code that could potentially generate a difference in the outcome of the result, specially depending on the environment you're testing it for instance a virtual machine.

There is probably an answer to this question on SO or even at DBA already, might be worth searching on those 2 for prepared vs escape

Oh you have no idea how much I searched, but the answers are so diverse

There is also good sides of it like re-usability of queries where as on escaping you did be creating a new query, and several other questions on SO that can point you why use prepared statement over escaping

wow I see so many questions there about it

Q: Who represents Wil Wheaton in "Big Bang Theory"?

5:28 PM

Yes and they all say "prepared statements is ze best" but I don't see it

But what if I'm only executing a statement once? Why would I need to prepare statements

By the way, how is real_escape_string different from addslashes?

Following the aesthetics-challenge my first question on this site: In several episodes of "The Big Bang Theory" Wil Wheaton appears. In the credits it is stated that he plays "himself". But I have problems with that statement. It seems to me that there are two different entities: The A-ctor o...

ontology philosophy-of-language aesthetics

My first thought was "You're way overthinking this." Then I realized it was the Philosophy site.

The celebrity paradox article on TvTropes (linked to by one of the answers) just makes my head spin.

Surely people assume that an actor isn't playing himself (unless he is).

Compiling allows you to fix errors quickly.

about Math.SE apparently hints are for homework level questions:

@RoryDaulton: Don't hesitate to ask because of anyone's reputation (see this meta thread). I thought about this a bit, and often if I feel a question is a homework problem, I leave a hint. However, sometimes I leave a more complete answer when either the hint I'd give would be too cryptic, or if a more complete answer does not give much more away. In this case, the hint would not give much more than cubing of squaring a polynomial. I may have misjudged. Thanks for your comment; it will affect my decisions in the future. — robjohn ♦ 4 hours ago

Math.SE is a strange place... on one hand, they've got nearly as big a homework problem as SO... and they've been arguing about if they want homework questions or not... on the other hand, they allow absurdly non-answers to get lots of up votes in homework level questions and fight tooth and nail to keep them.

@ratchetfreak they also have fun close vote wars: math.stackexchange.com/posts/902015/revisions

@MichaelT probably they can afford more relaxed attitude than Programmers or SO because of a higher barrier to entry. Not as high maybe as Code Golf but still. There's no place in math for bikeshedding like what line do braces go in or what is better of Python and PHP

"sanity checks: when do they become paranoid checks" can't imagine something similar at math. "When strict proofs become paranoid proofs"

@gnat "should I go all the way to the maxims when writing a proof or where should I stop?"

@ratchetfreak "what epsilon do you pick when calculating a limit?"
