The March Hare: Oct 15, 2006; _{Je r�ve d'un}
Wayne's World 3; Buglord

If I were to try to make a 'goon auth' system for a website (Like the one on awful yearbook that basically does the following "what is your user id? Here's a randomly generated 20 character code put it in the location field of your profile. [script checks profile if it is there] OK you are a goon, carry on. [if it is not there] try again or get out." How would I go about doing this? I assume its all php. I don't need a full blown script for it I just need to know how it is done. If I have been unclear please ask me to clarify anything.

http://www.awfulyearbook.net/register for reference I want it to be like that.

Just pull in the profile page and search for the string in what you get back. Haven't done php in a long time but I think you can use fopen. The url to use is like

I'm making a web page, but the table borders are somewhat stylized by default. I don't mind the look, but it looks weird colered, and I would prefer to be able to use a 1 pixel colored border if I can. How do I do it? This seems like something that should be obvious (and the default setting :/) border="1" doesn't work.

hey mom its 420: May 12, 2007

I'm doing something for my physics class and it involves a particle in a box problem in 3 dimensions. I have a function that generates further quantum states based on a starting state and a depth.

code:

def quantum_states(start, depth):
    if depth > 0:
        yield start
        for i, x in enumerate(start):
            start_list = list(start)
            start_list[i] += 1
            for state in quantum_states(tuple(start_list), depth-1):
                yield state

So an example of its usage would be

code:

>>> list(quantum_states((1,1,1),2))
[(1, 1, 1), (2, 1, 1), (1, 2, 1), (1, 1, 2)]
>>> list(quantum_states((1,1,1),3))
[(1, 1, 1), (2, 1, 1), (3, 1, 1), (2, 2, 1), (2, 1, 2), 
(1, 2, 1), (2, 2, 1), (1, 3, 1), (1, 2, 2), (1, 1, 2), (2, 1, 2), (1, 2, 2), (1, 1, 3)]

It works as it is, but you have to supply it a depth it's going to traverse. It works much like depth first traversal in a tree.
What I'd like it to do is to generate an unlimited amount of states, not just the amount that is inferred from depth. However, if I change it to this

code:

def quantum_states(start):
    yield start
    for i, x in enumerate(start):
        start_list = list(start)
        start_list[i] += 1
        for state in quantum_states(tuple(start_list)):
            yield state

and then try to get the first 10 states, I get this

code:

>>> list(x for x,_ in zip(quantum_states((1,1,1)), xrange(10)))
[(1, 1, 1), (2, 1, 1), (3, 1, 1), (4, 1, 1), (5, 1, 1), (6, 1, 1), 
(7, 1, 1), (8, 1, 1), (9, 1, 1), (10, 1, 1)]

Which makes sense, because without an edge condition, it just keeps going along the left branch forever. And that doesn't produce very useful results.

So how could I modify this so that it gives me an infinite sequence but doesn't just keep going along the left branch?

What you want in Haskell would be along the lines of:

code:

qstates s = s : concat [ [ (a+1,b,c), (a,b+1,c), (a,b,c+1) ] | (a,b,c) <- qstates s ]

So, by converting to explicit iterators for Python, we wind up with something like:

code:

def quantum_states( start ):
  yield start
  for state in quantum_states( start ):
    for i, x in enumerate( state ):
      l = list( state )
      l[i] += 1
      yield tuple( l )

(completely untested, because I don't like Python)

In Haskell, this code works well because the optimizer does the right thing and builds a cycle in the intermediate graph. I kind of doubt Python is going to be that smart, so you might want to build a wrapper that memoizes an appropriate window in order to avoid going linear in stack frames. Whether or not this is worth it depends largely on how expensive the continuations wind up being.

PHP/IIS/Windows XP

I wrote a simple script in PHP to upload a file with the eventual intent to store it in MySQL as a blob. The script retrieved the file successfully with no error code but the copy was still unsuccessful:

code:

$uploaddir = 'C:\\Inetpub\\wwwroot\\uploads\\\';
$uploadfile = $uploaddir.basename($_FILES['binFile']['name']);
$tempfile = $_FILES['binFile']['tmp_name'];

if (move_uploaded_file($tempfile,$uploadfile))
{  echo "upload successful<br>";  }
else
{  echo "upload unsuccessful<br>"; }

Because print_r($_FILES) shows no error and all of the paths to be correct, I suspect it's a permissions issue. How do I grant PHP (or IIS) the permission to write the file to and/or copy it from C:\WINDOWS\Temp to the uploads directory? Alternatively, if it's not a permissions issue, what is it?

Edit: question withdrawn, Internet Guest account needed write permission to temp directory and destination directory

What's the most efficient operating system for a web server?

I'm running AssetNow CMS on Coldfusion. My current OS is Windows Server 2003 on a shared server.

I'm moving to a dedicated server that I can call my own, and I'm looking for the best solution.

The most meaningful definition of "efficient" is strongly dominated by maintainence overhead, so the answer is "whatever operating system you are most familiar with and takes the least hassle to run the software you are already using."

Operating systems do have different scheduling and memory behaviour, but the differences are going to be overwhelmed by even minor hardware changes like adding RAM. Unless you are in a situation where you need extremely high runtime or will be constantly running at close to 100% load, you shouldn't care. If you are in such a situation, then the solution needs to be finely and particularly tuned to your requirements.

We will be streaming audio to thousands of concurrent listeners 24/7. I am just wondering what will handle the load the best.

I'm thinking it's best to stick with Windows Server 2003 simply for Windows Media Services.

If you are streaming the same audio source to all those clients, then it's hugely unlikely that the scheduling and cache differences between operating systems will be observable. If there are many different sources, then the Linux scheduling and pagecache might perform better, but adding RAM to a Windows-based server would overwhelm the difference. CPU usage is going to be comparable across the board.

It sounds like Windows Server 2003 already has the software and working environment you are used to, and has tools that will work well for your case, so it's obviously the right thing to use. Any money you "saved" over a year by switching platforms would be lost in added wages for programmer and administrator time in less than a week (probably less than a day if you're anything more than a 3-man shop), and migrating would almost certainly take much longer than that.

Is there a way to check if a read in string from fscanf() contains a newline in C? I know it ignores whitespace characters which presumably includes newlines, I just am looking for a way to tell if it has encountered and ignored these characters.

This probably isn't what you want to hear, but fscanf is a really terrible lexer, and when you get to the point of caring if a newline or something is present in the input, you should really consider moving to a lexer generated by lex or some other tool.

Can't you just do strchr('\n') (or strstr("\r\n") on windows)?

No the problem is that when you use scanf it removes the endline characters from the string.

I've been able to successfully load these by just using the assembly class, but I used the easier LoadFile method. This method may be what's tripping me up here.

Yup. Read up on Fusion to understand the semantics of how and where the Framework will look for an assembly to load using the Load() methods vs. LoadFile(). Also, make sure that the DLL's you're loading are valid .NET Assemblies, because I seriously doubt twain_32.dll is .NET

This was indeed true, I went back and rethought my logic. Each of the lines I was looking for was prefaced with a character to mark what the line did, so I just looked for those when I was reading in. The results are quite cool actually as I was reading in OBJ files.

I want to put together a site that will allow me to track fuel economy and maintenance for my car. I would like it to have separate pages for fuel and maintenance and also a couple other car-related costs I want to track, but I want to keep the databases separate from each other (hopefully that makes it less complicated). I want the page to show the data in a spreadsheet type format and at the top of the page it'll have an entry form for the date/#of gal/$per gal/etc... Would PHP work best for something like this? Also, at some point I would like to be able to update this from my cellphone.
