Programming :: Store The Data In Program In A Map Of Priority_queues?
Jul 30, 2011
I am trying to store the data in my program in a map of priority_queues an I am having a bit of trouble doing it. basically I am storing activities (ie watching tv, eating dinner, playing ping-pong, etc) and I want these event grouped by the day that they happened on.
my first thought was to use a multimap where the key is the date, and the value is the activity, however I would like to keep the activities in a specific order. I have tried to find the proper syntax for this but have frustratingly come up empty. Even google provided little assistance.

I am looking for a program to help me store, organise and retrieve information. The aim would be to keep notes from literature, concepts and ideas which i come across during my studies. It's always a hassle to retrieve this information when i have to write a paper for instance. So in fact what i need is a sort of wikipedia-like program where information is searchable and where perhaps hyperlinks could lead me from one word/note to another.

I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?
Quote:
Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
Code:
#include <iostream>
#include <fstream>
#include <strstream>

I have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.
Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.
Where does iTunes store its stuff?
Can I copy its data store to an external drive, and then into a linux home?
Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?
Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?
Supposing they are buying music through iTunes, what will happen to that account?
Finally, one of them has an iphone. Does that work with linux?
Ironic that an apple application is blocking migration away from windows.

I have connected a device to my linux system with a serial cable (rs232). The settings are: port /dev/ttyS0, baud rate=38400, data bits=8, stop bits=1, no parity, no hardware or software handshaking. I wrote a linux program that sends 1 byte to the device, but the device doesn't receive it. I know the serial ports are working because when I use the CuteCOM application to send data, the device DOES receive it, so obviously it is a problem with my code..
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

i wanted to capture the stdout and stdin of a child process within a parent so that any output of child is sent to the parent and any input taken from the parent. code is simple enough and i have followed all code guidlines on the internet (some guidlines do differ also) my select call either hangs if i do not give a tmeout and with a timeout it returns 0 descriptors to be written to or read from:
below is the simple code for parent:
int main(void)
{
int outfd[2];
int infd[2];
[code].....
why select hangs without a timeout ... why can it not detect that the pipe is write ready i.e parent can write to it ... if it does not detect tha read pipe as having data...

After a prolonged absence, version 4.10, I have started dabbling with Ubuntu again. It was a HDD crashing that sent me down this path. Needless to say, the ability to backup my user data to a second HDD is an important task to me. I'm currently using Back in Time to accomplish this and all is well. However, there is one thing missing. I can't locate my Tomboy Notes data within the file system. I expected to see a "hidden" folder in my /home, but do not. Where this information is stored so I can back it up as well?

I am trying to setup my ubuntu machine to automatically log some data I am trying to collect and write the data to a flash drive. I have everything setup so that when the machine boots up it starts that logging process. The problem I am having is that sometimes (not always) ubuntu creates a directory with the same path that I expect my flash drive to mount to i.e., /media/data/ then my flash drive instead mounts to /media/data_/. I need to know the path of the flash drive so I can store my data on it.

In what files/dirs in the home dir does xfce store the user config data?
Or if you like.
What files do I need to restore from backup in order to restore my xfce desktop with all the different settings I made?
Edit: All user config files is usually stored somewhere in /home/$USER/. And since all the programs, kde, xfce and gnome stores their config there, this question is about what files belong to the xfce desktop.
This is my guess of what files belong to the xfce desktop:
.config/Thunar/
.config/xfce4/
.config/xfce4-session/
.config/user-dirs.dirs

I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?

i have a loop which produces new value everytime it runs. i want to store the results in an array. how can i do dat??
loop is like:
a=0
declare v
while ((....))
do
v[$a]="$r"
let a=a+1
done
while doing this it is not treating v as array but as variable and it is overriding the value and old value is lost..i am using bash shell version 3.00.15

Code:
ls Again the command can be stored in a variable and then executed. Like
Code:
var=ls
&var
The above two codes are the same. The problem occurs when we try to pipeline it. Consider the following problem:
Code:
ls | grep *
works fine...but when we try to store it in a variable and run the command there is an error.
Code:
var="ls|grep *"
$var
how to store this kind of commands in a variable?
