I want to specify about 10 tables that should be checked before the application starts, since if they are empty the results are not so good!
Here is what I have so far:
//specify what tables we want to check
$db_array =
array("attendance_codes","ethnicity","generations","grades","grade_terms","health_codes",$
//walk the array checking each table for more than 0 records

it's not working,
To do this, can I do this?:
if (@ary = ""),
or is something more needed?
So I didn't notice when I setup my CentOS 5.5 server that I left / as RAID 0 on md1. All the rest are RAID 1. Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

I have trouble converting a short array to a char array
Code:
short pShort[4] = { 0x41, 0x42, 0x43, 0x44 };
How to convert this to a char array?
I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';
Can't single the cause of the error.

View 1 Replies View RelatedI'm writing an interpreter and it used simple association lists for mapping varaible names to their values. Here's the code:
Code:
#include "assoc_array.hpp"
#include <string.h>
using namespace LANG_NAMESPACE;
[code]....
I thought that I would replace it with a hash table to increase performance. Note that I decided to store linked lists in the buckets instead of the actual values, in case the hash function outputs the same index for multiple variable names:
Code:
#include "hash_table.hpp"
#include "assoc_array.hpp"
#include <string.h>
[code]....
It runs in about 0.333 seconds on my machine. Since I'm using git version control, I decided to bring back the old version that used association lists. To my amazement, it ran 3 times faster, completing in 0.116 seconds! Is my hash table implementaion really that bad, or is this a really poor benchmark (and real-world code actually will be faster using the hash table)?
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.

View 1 Replies View RelatedI have one hard disk for my root partition and a disk array on a separate mount point. I rebuilt my disk array, but I didn't delete my original mount points beforehand because I was hoping it would just "pick up". So now when I boot up, the OS tells me that the filesytem check fails because it can't find the array to map to the mount point. I know that I need to edit my /etc/fstab and remove the line that defines my mount point on the disk array. But it appears to be read only filesystem when I am in repair mode. I can't force the write with vi.

I have a GeForce 8600M GS card in a Dell Vostro 1710, which has appeared to be playing up lately, but I'm unsure whether it's the hardware itself or have I not properly set things up.
I have Ubuntu 10.04 installed with compiz, and 'rotate cube' enabled. The 'deformation' is set to cylinder. I recently tried using rss-glx (really slick screensaver) when the slow-down and screen freezes happened.
The symptoms:
Odd behaviour begins after attempting to log in after the screensaver has blanked the screen, i.e. screensaver ran for a while then the screen blanked. When logged back in, a 'cylinder' rotate freezes and the screen does not refresh. Clicking around the screen refreshes it somewhat. Switching between screens becomes next to impossible and a restart is required.
In general rotating the cube is OK, rotating the cylinder seems a task on the video card and rotating the sphere is horribly slow.
Things done so far:
Each time I log in, I need to open the NVidia settings and change the powermizer to 'prefer maximum performance'. On next reboot I will try this in xorg.conf code...
My questions are:
- How can I verify the card is working correctly, enough to be able to decide whether it's hardware or software at fault?
- If the hardware is proven to be OK, what am I then leaving out?
We've just set up 3 Dell systems with 64 bit Red Hat Enterprise Workstation 5. As part of our system configuration we point the user authentication to our LDAP server, and automount people's home directories from our fileserver. At this point, our security people do some configuration and we get it back.
We are typically running KDE. On all three machines, when you plug a USB stick into the system, the familiar window pops up asking you what you want to do - open the contents in some program, open a file viewer, etc. and the stick shows up in /media When you stick a CD or DVD into the drive nothing happens - you don't get the options window and nothing appears in /media I'm trying to get an idea of how the automount process works, and where I may have stepped on it. We've got three more identical machines that haven't been installed yet, so my plan is to check the ability to automount CDs at various stages of our setup process.
I have a text file from which i read a number of names with their lengths at the run-time.Now i want to created a char array having the length and name as already read from the text file at the run-time. There is no compilation involved. Every thing is happening at the run-time. I tried using STL like map along with malloc but i am unable to name an array at run-time. I can keep some type of mapping with previously created arrays
