I'm learning PHP and I was curious about this. I've learnt about cookies and sessions, and I'd like to know - which one do you use for a shopping cart? What's the actual mechanism behind it? As the user builds up a cart full of stuff, is the data for that maintained on the server-side in a MySQL database or something?

View 1 Replies View RelatedI'm about to start a new build for my primary machine at home. The plan is to load up a server/workstation motherboard (ASUS KGPE-D16) with two 8-core chip, as much RAM as it will take (32GB) and to put two graphics cards in it. One to power my main 24" monitor (ideally via HDMI) and the other card to power two screens, one 24" on each left and right side via DVI (unless I can find a dual-HDMI card that meets my needs).
Does that make sense? Here's my question for this awesome group of intelligent individuals: What video card model should I choose? Obviously, I'd like them to match so I can SLI / CrossFire if I really want to, but what setup should I plan on to have a good experience managing multiple displays on multiple video cards?
Oh, and budget is probably up to about $300 per card, maybe a little more if it makes a lot of sense.I'm not alone in having tons of problems with trying to get multi monitor support in the last few versions of Ubuntu, and honestly it's the only reason why I'm still running Windows7: the multi monitor support is just SO DAMNED easy! I shouldn't have to spend this much energy thinking about video card model- it should just work, shouldn't it?
Has anyone ever worked in the development of a cart application able to handle transactions and payment. I am not just interested in the database processing but how the money is being transfered. Do you need some server requirements? Any book(s) that you find useful to read? or online source ?

View 6 Replies View RelatedI just started messing around in Linux programming, and I wanted to create a simple test program to open a file, read to it, and write to it. I can open and read it, but write always gives errno = EBADF. I've messed with file creation permissions and I can figure out why write() thinks it's a bad file descriptor but not read().Here is my code:

View 6 Replies View RelatedI've been working at learning how to write makefiles and I'm a bit stuck.
I've got a fairly simple project that will eventually be a framework for TCP/IP Communications in evolutionary algorithms that I've been using Eclipse to develop.
For personal development I want to learn how to write makefiles by hand but have gotten kind of stuck
Here is the makefile as it stands now:
Code:
Port and Mailbox are a virtual class and a template class respectively.
I get these errors when I run make:
Code:
So for some reason every single function in the Connection class has been defined multiple times. I assume because it's included as a dependency for multiple targets, but I've seen this in numerous examples that apparently work.
Everything in libpthread is undefined because I'm not linking in the library. I've tried adding the library options to the LDFLAGS variable but that doesn't seem to work either.

I am trying to write a gui app with python2.6.4 and wx on win XP. I am attempting to resize an image with Imagemagick from within the program using os.popen and os.system in a thread.
Code:
os.popen("mogrify -resize " + str(x) + "x" + str(y) + "!" + " images/static/" + my_ref + ".gif")
orCode:
os.system("mogrify -resize " + str(x) + "x" + str(y) + "!" + " images/static/" + my_ref + ".gif")
they both work as far as resizing the image but when os.system is used a command shell opens during the mogrify and when os.popen is used the command shell does not show but the rest of the program freezes until mogrify is done.
I would prefer that the program did not freeze during this process and the command shell did not show.I have tried using wx to scale the image but the scaled image looks crappy.anyway is there a way to use os.system and not have the shell show?
I'm trying to write a toy linux shell. For starters this is what I'm trying to do:
1. Start a new process with fork.
2. Execute a program in the new process with execl().
3. Redirect the output from the new process from STDOUT to another file descriptor, using dup2(2).
4. In the parent process, read the output from the child process and write it to the screen.
Creating a new process and executing a program in it is no problems, the problem is that I can't seem to capture the output from it in the parent process.
Code:
//digenv
//C++arl 2011-03-24
#include <stdio.h>
#include <sys/types.h>

I'm trying to write a .sh script that allows me to run multiple other .sh scripts at once.
My problem occurs within a Variable:
I have set
S1 to S7 to be the name of the .sh
A="7"
B="S$A"
C="$S$A" <- and this is where my problem is
I want C to be the content of S7 till S1 but if I run this line it will of course look for the content of S and link it with the content of A.
How can I correct this?
Edit:
WHERE="/home/X/Y/"
SH=".sh";
A="7";
B="S$A";
C="$B";

and my code expects something like [URL] I need to modify the code, such that it will find the actual file.
I know, I know..."How long is a piece of string"?
I have one of these devices:

Of course, it's Windows only, and XP only at that. However, the data that needs transferred between the device and the computer should be fairly basic, unless it offloads a lot of processing to the computer. I'm not a programmer, nor do I play one on TV, but I have written some fairly complicated microcontroller programs and some basic Java GUIs. Besides writing the actual code, how hard is it to do whatever needs done to make a Linux device driver, apart from the code to make the device work?

How do you write a program that is independent of the UI (the functionality is a library, and you have, for example, CLI and GUI interfaces as separate apps). The problem I have is how to report status and prompt the user from within UI-independent code? I could split it into parts that do not require any user interaction, but then most of the functionality will be in the UI, not the backend.
