Happy new year everyone :)

i realize this isn't the appropriate mailing list and i risk being
black-listed (flame, defamed, ignored, etc.).
i occasionally use temporary emails when registering for forums or to get
some shareware (we've all done it, don't give me that look, i have given
what i could, when i could) and while i like the way mytrashmail.com works,
i don't like having mytrashmail.com as part of the temp addy.
does anyone know of a similar service that uses a more enticing domain?
thank you,
jason

you-can.diy
a domain costs pennies and all the required software is free.

jason:
A couple ideas:
1. I've used the same email address (my name) for almost 12 years.
It's on more spam list than I care to count, but that doesn't brother
me because I filter all my email through spamcop.net. My spam count
is below 5% of total email received BY ME. You might consider their
services for $35US pr year.
2. You can always buy domains (<$10 per year), set them up via cheap
hosting (<$10 per year), and have as many addresses as you want.

PS: I've never used temporary emails for anything other than testing.

As much as you make it use.

It's impossible to correct remove semaphores with sem_remove function
when I use them to provide execution of concurrent processes.
When the last process releases the semaphore I should be able to remove
it. But I don't know if another process haven't acquired the semaphore.
For safety reasons I don't remove released semaphores from system.
Now, If I get 128 semaphores and I execute sem_get one more time I will
get warning.
So, I can't remove semaphores (because I don't know if another process
is using it) and I can't get next semaphore.
I will try to tell about my sugestion.
I assume that I have a function my_sem_remove($sem_id):
function my_sem_remove($id) {
if(Semaphore $id isn't acquired and its FIFO is empty)
sem_remove($id);
}
None of instructions in this function can be interrupted.
So, now the problem is simple to resolve:
$id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
sem_release($id);
my_sem_remove($id);
But now, two instructions: sem_release and my_sem_remove are not needed.
It's simple to replace them by one function my_sem_release:
function my_sem_release($id) {
sem_release($id);
my_sem_remove($id);
}
For reasons which about I will write later those instructions can't be
interrupted.
So, my example look like this:
$id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
my_sem_release($id);
But let's imagine two concurrent processes executing code above:
PROC1: $id = sem_get(ID);
<--- interrupt
PROC2: $id = sem_get(ID);
sem_acquire($id);
CRITICAL REGION
my_sem_release($id);
<--- interrupt
PROC1: sem_acquire($id); <--- Uuups!! Error: semaphore doesn't exists,
PROC2 has removed it.
My solution:
Instructions sem_get and sem_acquire can't be interrupted.
So, I assume that there is a function my_sem_acquire:
function my_sem_acquire($key, $max_acquire = 1, $perm = 0666,
$auto_release = true) {
$id = sem_get($key, $max_acquire, $perm, $auto_release);
sem_acquire();
return $id;
}
None of instructions in function above can be interrupted.
And finally correct example:
$id = my_sem_acquire(SEMKEY);
CRITICAL REGION
my_sem_release($id);
It's the best solution, without danger of operating on not existing
semaphores. Also, unused semaphores are automaticcally removed. The
problem is, that functions my_sem_acquire and my_sem_release can't be
witten in PHP so it must be done in C inside source of PHP.Wojciech Malota

Hi gang:
I've just noticed that the php.net logo changes with the seasons -- I
think that's neat, in fact, I do a similar season change with my site.
However, does the php logo change for those in the southern
hemisphere? In other words, for oz programmers, do they see a
different logo? If so, how does one (or can) detect the user's
hemisphere?
Thanks.

Detecting a user's geographical location is a bit hit and miss, but there are
some databases (both free and paid for) that you can use to map an IP address
to a country and at that level it's usually fairly accurate (the further you
try to narrow it down, the less accurate your results will be). Have a look at
these databases, and a search for 'geoip' or 'libgeoip' on Google should get
you some more results:

Hope this helps.

Hello Everyone,
I'm trying to write a PHP script that opens a binary file, reads the
binary in chunks, checks those chunks for a certain binary string, and
then if the string is found, it replaces the string with another binary
string. The script should then a copy of the file, including the
changed bits. But for some reason, the script is not replacing the
binary string.
Here's the source code:
<?php
$in = fopen("C:\NeighborhoodManager.package", "rb");
$out = fopen("C:\NeighborhoodManager2.package", "w");
$count = 0;
while (!feof($in)) {
$count++;
$buffer = fread($in,50000);
if
(eregi("0101001101110100011100100110000101101110011001110110010101110100011011110111011101101110",$buffer))
{
$buffer2=eregi_replace("0101001101110100011100100110000101101110011001110110010101110100011011110111011101101110","0101011001101001011000110111010001101111011100100110100101100001",$buffer);
}
else
{
$buffer2 = $buffer;
}
fwrite($out,$buffer2);
}
fclose($out);
fclose($in);
print("About ".($count*50000)." bytes read.\n");
?>
The resulting file is not changed at all, the size, md5 sums, and
contents are the same as the original file. The original file is only
40,960 bytes on the disk, so the script reads the file in one pass. I am
sure the binary string is in the original file, and I have tried reading
the file into chunks as small as 64 bytes. I am at a loss as to what is
happening, so I would appreciate any help.
Sincerely,
Philip W.
