Alright, really dumb and most likely easy HTML question, but I don't know much of any html and our web guy doesn't know how to do this off the top of his head:

I need an easy web submission form for service requests, and we have everything flushed out except I want some of the text boxes to contain that grey, italic text that goes away when cursor focus is brought to the box or something is typed in to it. I have no idea what this element property is called though, and googling a general description of it turns up a mess of garbage. Can someone point me in the right direction or give me some quick example code to give to my web guy?

CSS:

code:

.something { color: gray; font-style: italic; }

HTML:

code:

<input type="text" value="some text" class="something"
  onfocus="this.value = ''; this.setAttribute('class', '')">

Tested once in Firefox, but should work. May not be the best solution, though.

edit: table breaking is always fun.

I am currently running GHCi on Windows, the version is 6.8.2 and I seem to be missing some functions that I find around in various Haskell references. For example when I try using nub, sort, or groupBy it says that they're not in scope. It looks like about 25% of functions are missing. Am I using an older version or do I have to import some modules for those functions to work or what?

The three functions you mentioned are all in Data.List. To import modules in GHCi you use :m +<name>.

The first line of the loop is for i in `seq 0 1000000`, and you need spaces before the ]s (also, you might want to use elif instead if fi/if). Otherwise, what poopiehead said.

Edit: I can't read.

Edit 2: vv Use `seq 0 20 1000000`.

Is there any way to get sh, in the context of a shell script, to interpret a given string as a variable name. I'm trying to do an assignment like:

var1=\$$var2

Where var2 will be a number, so I want to get the var2-th command line argument and store it in var1, yet the code as written acts like var1='$var2'

Is there any way to get around this?

eval "var1=\$$var2" works, but I'm sure there's a better way.

You can use GHCi for debugging, which would be simpler than trying to coax gdb into it. I don't know about Hugs or whatever, though.

I don't know C# that well, but a Dictionary<char, int> would work, with something like

code:

var d = new Dictionary<char, int>();
foreach (char c in str) {
  if (d.ContainsKey(c))
    d[c]++;
  else
    d[c] = 1;
}

Alternatively, you could probably do in one line using LINQ.
