The brute-force solution is to issue:

make -B
This will rebuild all targets, regardless of timestamps.

Ofcourse, this will get very annoying/timeconsuming when working on large projects, so a...

Your 'highest bit' code doesn't do what you meant it to do; you left out CHAR_BIT:


result = value >> (sizeof(unsigned int) * CHAR_BIT - 1);


The sizeof operator yields the size of its...

Never, ever use gets(), use fgets():


fgets(s, 100, stdin);


Also note the only portable values to return from main are 0, EXIT_SUCCESS and EXIT_FAILURE.

What you should do is remove onclick="validate();" from the submit button, and add onsubmit="validate();" to the <form> tag.
And the validate() function should look something like this:

...

There's not a lot of context to determine what could be wrong, but I'll give it a shot.

Normally when doing client-side form validation with Javascript, you use the 'onsubmit' event of the form to...

The method is called 'next', no leading or trailing underscores.

That's were the error is occuring, like the message said, old-style (pre-ANSI) parameter declarations mixed with prototyped (ANSI) function definition.
Two quick solutions here: either remove the...

I have used both, and I prefer the newer mysqli over mysql. Mysqli allows for an OO approach to querying databases, which leads to cleaner code (IMHO). That said, these days I prefer to use PEAR's...

But it isn't really a leak, the memory is freed by bash when bash exits. Of course, it would make sense to free the memory used by a loop after the loop has finished, but there may be reasons why the...

This issue has been reported on launchpad: https://bugs.launchpad.net/ubuntu/+source/bash/+bug/82123. It seems the bash maintainers don't see this as a problem, so I don't expect this will get fixed...

You can tell find and xargs to use '\0' to delimit filenames, rather than whitespace. Find needs the option '-print0' and xargs needs the option '--null'.

Example:


find /usr/src -name *.c...

Although a simple BBcode parser isn't that hard to write, there are still a lot of pitfalls, such as users embedding html code in their posts (which needs to be filtered out), and...

Don't rely on that. In a boolean context, NULL is indeed false, but NULL isn't always all-bits zero. A implementation is allowed to, for example, declare NULL as (void*)0xDEADBEEF.

A '0' numeric...

Thanks for taking the time to explain your views. The abs guide is indeed very inconsistent in its examples, perhaps because many people contributed code snippets. (it should be the authors job to...

Any particular reasons for this? I know it tends to experiment a lot and isn't very clearly written, but I found it to be quite useful as a reference. It does often fail to mention portability...

Doxygen expects a documentation block to belong to whatever comes after it, so the documentation goes before the function definition. There are exceptions though: preprocessor conditionals. Doxygen...

MySQL doesn't support function calls as default values, only constants. However, for this particular problem, you can change the field type to 'TIMESTAMP':



create table users(

I was playing with the same idea, would work fine for just a few searches on smallish strings. But it would add a lot of overhead for large strings with a lot of searches.

A good example of 'When...

As tomazzi already mentioned, sed has the -i/--in-place option:



for f in * ; do
sed -i '1s/^/Subject:Your Daily Book Part, Tarah.\n/' "$f"
cat "$f"
done

I would also recommend designing the database first, once the database back-end is set up properly, the front-end tends to write itself since the database design dictates the design of the front-end....

Since void is an incomplete type, applying the sizeof operator to void is a constraint violation, which requires a diagnostic. At least that's what I make of it, though I'm not that well versed in...

I assume you mean unsigned char *, which is close to the generic pointer type pre-ANSI, which was char *.

It depends on what you want. As far as I know Awk doesn't have any built-in statistical analysis tools/functions, but since Awk is a full-fledged programming language with support for floating point...

This sed command:


sed -i 's/foo/bar/g' SOMEFILE

can be implemented in awk like this:


awk '{ gsub(/foo/, "bar", $0); print }' SOMEFILE
