I'm currently teaching myself perl. I'm trying to write a program that unscrambles words by comparing each element in the array. There is an input file where you type the words to be unscrambled and there is a word list file containing approximately 1300 words. After everything has been processed the program is supposed to paste those words to an output file.
Code:

#use strict; #always add this in the beginning of code.

#open(INFILE, '<', 'sample.txt'); # For reading

I have two questions - is there a more compact way to strip off the process names? usalso i want to get rid of the errors after extracting the hostname. It is complaing about $arry[1]. using my $arry[1] is not allowed. Assigning the slice to a value, as is 'my $sliced_arry = $arry[1]; print $sliced_arry , does not work either.

Use of uninitialized value in pattern match (m//) at newcomm_stats.pl3 line 7, <NEWCOMM> line 16 here i get what i want - just the host name, but still get those nasty errors. assigning a value to $1 does not work, and localizing $1 with 'my' is not allowed.

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
I'm looking for a function (prefer POSIX, but Linux specific would do if it has to) to get the current timezone offset. For my location, eastern USA, that should be -14400 when daylight time is in effect, and -18000 otherwise.
View 1 Replies View RelatedI'm using pyqt3 for my app and am lost on even how to attempt this task... On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.

create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

I have a clean install of Fedora 12 and trying to mount a second hard disk with data created under Fedora 8. Nautilus lists the hard disk and can see all the folders and files under Places > Computer. However, Nautilus only lists hte hard disk (/dev/sdc) but no partitions (e.g. sdc1, sdc2) under Filesystem. LVM shows Partition1, Partition2 and UnPartitioned space under /dev/sdc. LVM shows Partition2 as 'uninitialized Disk Entity /dev/sdc2'. If I try to 'Block Initialize' Partition2 (which is the largest listed partition), LVM warns all data in the partition will be erased. A partition with all the data is on the hard disk because Nautilus can see it but the partition is not listed under /dev/sdc so I can mount it.
View 7 Replies View RelatedWhen I run ddclient with an existing ddclient.cache file I get errors saying "uninitialized value" and the remote IP address does not get updated. This pretty much renders ddclient useless. If I delete the cache file then things work fine and the IP address *does* get updated (if need be). I happen to be running version 3.7.3 of ddclient but I've tried this with ddclient 3.8.0 and the result is exactly the same except that the line number in the error changes to line 2030.
Here's the code at that line number :

I always manually check Update Manager and there are updates, but I never received any kind of notice indicating such. I thought some sort of popup or notice was supposed to appear in the panel or something to alert me that updates are available? Am I mistaken? Is there a setting I need to activate be alerted that updates are available?
