The idea of starting with a number that needs to go down some way or another is an appealing one because it suddenly becomes attainable to find a solution that as some claim to being at least as good as all other solutions.

User recognition without cookies or local storage
...an Artificial Neural Network (which uses fuzzy logic). In either case, the idea is to train your system, and then combine its training with Bayesian Inference to increase the accuracy of your results.
The NeuralMesh library for PHP allows you to generate Artificial Neural Networks. To implement B...
Defeating a Poker Bot
...
Ideally the only valid solution is to create a honeypot logic that lures an engaged bot by providing the temptation of a more favorable logic condition that favors the bot's most ideal behavioral responses. Once the bot is e...

dynamically languages makes them
ideally suited for prototyping systems
with changing or unknown requirements,

What is a “cache-friendly” code?
...are the cache memories, named L1, L2, L3 in decreasing speed and cost. The idea is that most of the executing code will be hitting a small set of variables often, and the rest (a much larger set of variables) infrequently. If the processor can't find the data in L1 cache, then it looks in L2 cache. ...

Sometimes denormalisation is a good idea
Denormalisation is a commitment to a particular join strategy. As mentioned earlier, this interferes with other join strategies. But if you have buckets of disk space, predictable patterns of access, and a tendency to p...
Context switches much slower in new linux kernels
... that setting idle to mwait if supported by your hardware is a much better idea. It seems that the use of the MWAIT/MONITOR instructions allows the CPU to enter C1E without any noticeable latency being added to the thread wake up time. With idle=mwait, you will get cooler CPU temperatures (as compar...
