HTTP Polling vs. HTTP "pushing"
Polling creates requests, one per second, 5 per second, whatever you regard as an acceptable latency. This can be rather cruel to your infrastructure if you do not configure your (Apache?) and (php?) well...
Try-catch speeding up my code?
...ssumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a...

Currently, the JVM does more aggresive runtime profiling and optimization (i.e. Hotspot). CLR currently does JIT optimizations, but not runtime optimization (i.e. replace code while you're running).

What is the difference between LR, SLR, and LALR parsers?
...
The basic difference between the parser tables generated with SLR vs LR, is that reduce actions are based on the Follows set for SLR tables. This can be overly restrictive, ultimately causing a shift-reduce conflict.
An LR parser, on the other hand, bases reduce decisions only on the se...
