RDBMS-based job queues have been criticized recently for being unable to handle heavy loads. And they deserve it, to some extent, because the queries used to safely lock a job have been pretty hairy. SELECT FOR UPDATE followed by an UPDATE works fine at first, but then you add more workers, and each is trying to SELECT FOR UPDATE the same row (and maybe throwing NOWAIT in there, then catching the errors and retrying), and things slow down.
On top of that, they have to actually update the row to mark it as locked, so the rest of your workers are sitting there waiting while one of them propagates its lock to disk (and the disks of however many servers you're replicating to). QueueClassic got some mileage out of the novel idea of randomly picking a row near the front of the queue to lock, but I can't still seem to get more than an an extra few hundred jobs per second out of it under heavy load.
So, many developers have started going straight t

| This program is an adaptation of the Mandelbrot program | |
| from the Programming Rosetta Stone, see | |
| http://rosettacode.org/wiki/Mandelbrot_set | |
| Compile the program with: | |
| gcc -o mandelbrot -O4 mandelbrot.c | |
| Usage: |
It is well know that through the ip and ifconfig commands it is possible to change a MAC address temporarily, meaning the change will not persist across host reboots.
But what if you would like to change your MAC address in a more permanent fashion? Is there a way to, through software, permanently change your network interface card's MAC address?
It turns out the answer is yes, and the tool to do so is called ethtool.
Ethtool comes pre-installed on many stock distributions of Linux, but can also be installed from your package manager of choice if necessary.

| * This is an example of a practical encoder and decoder for base-62 data in PHP | |
| * It differs from the majority of examples in that it's fast enough for moderate data sizes, unlike multiprecision converters | |
| * To be practical, base-62 encoding needs to use internal chunking and padding because base-62 does not fit exactly into any integral number of bits | |
| * This means the output is not quite compatible with multiprecision conversions, | |
| * but the encoded data retains all the desirable properties of base-62, so (unlike any base-64 encoding) it's URL, DNS, email address and pathname safe | |
