This wastes no more than > 50% of the memory needed for that list, but has various advantages > -- and I'm damned if I can remember exactly what those advantages > were. Allocating extra memory usually requires the following steps: - Allocate more memory - Copy all data from old to new memory - Deallocate old memory That second step requires N actions if there are N data items in the list. If you add one 'block' of memory to the list for each item you add, you waste no memory, but every item added requires N steps to copy all the old items. That means that after you've added N items, N**2 steps have been taken. That's very bad for performance. If, on the other hand, you double the memory every time you run out, you have to copy much less data, and in the end it turns out you need roughly N steps to add N items to the list. That's a lot better, isn't it? Sybren -- The problem with the world is stupidity.

I thought the same thing after spending two hours removing some adware I found. > Ever since Win2K got rid of the constant blue screens, the reasons > for switching over to Linux have grown less and less urgent. One thing in Linux (Gnome actually) that I miss in Windows, is that in the latter you need to grab the title bar of a window to move it, and the edge to resize it. In Gnome, I can press the ALT key and drag the window with the left mouse button and resize it by dragging with the right mouse button. When moving, it doesn't matter where your cursor is, as long as it's inside the window. For resizing, it grabs the closest corner and moves that. It's like having a scrollwheel on your mouse. If you've never used such a thing you don't miss it, but if you're used to it, it's a major annoyance when it's gone. > The 'Nix desktop environments are growing visibly more mature with > each passing year, but device support in Linux is still decidedly > inferior and it still takes far too much time to do some things you > take for granted under Windoze. When I replaced my CPU, motherboard and RAM, I had to reinstall Windows and all applications. Linux just booted. When I upgrade my video card, Linux just accepts it without even a single message. On Windows I have to do a reinstall of the video drivers. I think that everybody is influenced by their own experience. Here are a few of my reasons to run Linux, besides the ones already mentioned: - Window management in Linux is separate from the application. That means that a non-responsive (crashed or just very busy) application can still be minimized or moved. - If I log in and my desktop is shown, I can start working immediately. No need to wait for all sorts of things in the system tray to start up first. - Software installation on Linux usually works via the distribution's package manager, so it's one application for almost every software install. It also automatically downloads and installs all required libraries etc. - No need to defragment my harddisk. - No viruses/spyware. There are only two downsides I notice: - There are some games I want to play which aren't available on Linux. That's the only reason I run Windows, btw. - I have to be a little more picky about the hardware I buy. Sybren -- The problem with the world is stupidity.

If you notice yourself using such functions, it's ususally a lot

A better way is to use a queue. I had the same problem with a similar piece of code. The only thing why you're using a stack is to move to the "next" point, without going back to a visited point. The non-recursive solution is to mark all visited points as such, only consider non-visited points, and then append the coordinates to a list of points yet to visit. Then keep looping over your code until either you found the solution to the maze or there are no points left to visit. Sybren -- The problem with the world is stupidity.

OPs way is faster. A 'try' block is very fast, but trowing & handling
an exception is slow.

I think this has the potential of being faster than OPs method,

Check the web server's error logs. My solution was to take a look at Cheetah. It's a template engine that's written in Python. I've written a mod_python handler for it so I can easily create & edit my website using Cheetah as a template engine. Check out http://www.unrealtower.org/mycheetah if you want to read more about the handler & other stuff I wrote. Perhaps you can even help me improve it!

Re: Should I use "if" or "try" (as a matter of speed)?
Steve Juranich enlightened us with: > Without fail, when I start talking with some of the "old-timers" > (people who have written code in ADA or Fortran), I hear the same > arguments that using "if" is "better" than using "try". Then here is the counter argument: - Starting a 'try' is, as said somewhere else in this thread, a single bytecode, hence simple. - Those old-timers will probably check the data before they pass it to a function. Because their function has to be stable and idiot-proof as well, the function itself performs another check. Maybe the data is passed even further down a function chain, making checks before and after the function calls. After all, we want to be sure to only call a function when we're sure it won't fail, and every function has to gracefully bail when it's being passed bad data. This means that there will be a _lot_ of checks in the code. Now compare this by setting up a single try-block, and catching the exception at the proper place in case it's being thrown. The important part is this: those old-timers' "if" statements are always executed - it doesn't matter whether the data is correct or incorrect. The "heavy" part of exceptions only comes into play when the data is incorrect, which by proper design of the program shouldn't happen often anyway. As far as I see it, try/except blocks are "cheaper" than "if" statements. Sybren -- The problem with the world is stupidity.

Why aren't these enlightened-by-the-gods > know-it-alls as profitable as these obviously ignorant companies? They write software with huge security holes. Direct3D still isn't as stable as OpenGL. It takes ages for them to create security patches. The things I mention are *not* caused by their nice and clean way of coding. As a matter of fact, they use goto to jump from one function to another! And to make sure a 'return' doesn't return to the last call, but to some other, they combine this awful use of goto with manual stack manipulation. And they do all of this in C (or some derivative) so if one function changes it's parameters, all the manual stack modifications and gotos need to be checked for correctness. I'd rather use an exception, or better even - write small functions so I can call 'return' instead of doing 'goto EXIT'. Sybren -- The problem with the world is stupidity.
