I'm a beginner in Mathematica. Like shown in the image below, I'm trying to put hat and bar to some letters (I just want to write vector notation) but only some letters can have them. What's wrong with how I do?
If you could provide online resource that covers these syntax, that would be more appreciable. Thank you.
(Environment) { Mac OSX 10.7, Ubuntu 11.10, Ubuntu 10.10}, Mathematica 8.0.4 Student Edition
Use OverHat and OverBar:
OverHat /# CharacterRange["a", "z"]
OverBar /# CharacterRange["a", "z"]

I wonder how it is possible to make a visual presentation of algorithm.
I found a very good visualization in Wikipedia like following:
If you know how to make a similar presentation, please let me know.
There are lots of libraries in various languages that can be used to visualize whatever you want, but according to this page:

The picture you're looking at was:
Created with: Ruby 1.8.4, RMagick.
Just for reference.

The following link mentions some types of dynamic programming:
http://www.mii.lt/olympiads_in_informatics/pdf/INFOL056.pdf
one of which is "broken profile".
I am pretty sure it is a valid term since I have seen references to it in other programming competition sites like TopCoder and CodeForces.
But I can't seem to find anything on this topic. This term has been used mostly by Russian sources.
Does anyone what if means, or what kind of problems within dynamic programming it solves? Or even better a tutorial?

How do I use separate synonym dictionaries for websolr?
(There is only one synonym file in configuration panel. I probably need separate synonym set for each language)
Right now we only support the one synonyms file. We've got some ideas for more flexible configuration that may address this in the future. Best to ask us these kinds of questions at our official support channels: http://help.websolr.com/

hello i need to find the decomposition of this matrix
Matrix
but as you can see wolfram dose not solve it.
it is strange because for example it can solve this one:
Matrix solvable
which contains parameters as the same above.
How can i make the decomposition of that matrix with any kind of software ?
I can solve this using Scilab Programming language? (which is open source) or R or Octave or things equivalent...
thank you
Well it can be done with MuPad, but it is not free.
My guess is that this matrix is too big for the free version of W/Alpha.
It can also be done with wxMaxima and it is free.

What does the term "Coding in Vacuum" mean? I have heard the term before but I am unable to find anything on Google that is relevant.
I interpret this as a derogatory comment about someone writing software while not considering the greater context of the project. For example:
"Didn't Bob know that this email client was supposed to handle emails
with images?"
"I guess not, I think he was just coding in a vacuum."
I like this answer from the English Usage StackExchange:
