Hello,
I recently converted one of my perl scripts to python. What the script
does is simply search a lot of big mail files (~40MB) to retrieve
specific emails. I simply converted the script line by line to python,
keeping the algorithms & functions as they were in perl (no
optimization). The purpose was mainly to learn python and see the
differences with perl.
Now, once the converted script was finished, I was amazed to find that

I was wondering what the best solution is for making large numbers of
TEXT (or BLOB?) fields searchable. For example, if I have a forum,
what is the best way to be able to search for specific words? How
about exact phrases?
I saw a solution where all words are preindexed in a "dictionary" like
table and then another table stores the word matches. That seems
really fast, but it has two major problems: 1) it can't do exact
matches, and 2)...

Dear experts,
I am new to c++ (arriving from java) and I am having to implement a
data table that contains cells with numbers and cells with text. I
would appreciate any general indications about what would be the best
approach, bearing in mind that performance will be critical.
Many thanks

Hi all,
I need to write a function to search and replace part of a char*
passed in to the function. I came up with the following:
char* search_and_replace(char* source,char search,char* replace){
char* result;
size_t l = strlen(source), r = strlen(replace), i;
int number_of_replaces = 0;
for(i = 0; i < l; i++){
if(source == search)

If I have an array of data that I know to be sorted in increasing
order, and the array is less than 50 elements, and I want to find the
first element greater than a certain value, is a simple linear search
the best here(for loop from beginning to end of array)? It seems like
some other search algorithm like binary or whatever would be of no
benefit on this data set.

What is the *fastest* way in .NET to search large on-disk text files (100+ MB)
for a given string.
The files are unindexed and unsorted, and for the purposes of my immediate
requirements, can't be indexed/sorted.
I don't want to load the entire file into physical memory, memory-mapped files
are ok (and preferred). Speed/performance is a requirement -- the target is to
locate the string in 10 seconds or less for a 100 MB file. The...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
