Back in the past there was something called hyperthreading where a single CPU core acted like two cores. But is it possible to merge two CPU cores to an single one to improve performance on programs that doesn't use multiple cores decently? (from old games to the X Plane 11) Answer Short answer: No. Somewhat longer answer: Cores on a multicore chip are basically separate physical processors. Hyperthreading allows you to split one physical core into, e.g., two threads. The advantage of this is that the single core can swap back and forth between threads so that when one thread is waiting (for I/O, for example) the other thread can be resumed. Two threads on one hyperthreaded core share resources, allowing for very efficient context switching between threads. So why can't you do the opposite? Well, just picture it. You have two physical cores but only a single process. There are two possible scenarios: The executing code can be run in parallel. In this case, you would just have...

I'm using a Core2Duo Mac mini with the latest OS X 10.6 version. Though the option "Use LCD font smoothing when available" is selected in the System Preferences, Appearance page, when I take a screenshot and zoom-in only gray text is shown, no colored borders on the fonts. How I can activate LCD sub-pixel antialiasing on OS X 10.6? Answer OK, I've found the solution at welp's blog : just execute following command defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

Is it possible in linux to determine how long a file has been open for? I have a process I suspect is performing long running operations on some files, but I'm unsure how to check.

On my computer or on the router? Or both? I know how set them on each, I just need to know which one, or if I really need to bother.

What I want to do is, if a table is split into two or more pages, add the original table caption with the word "continued" attached.  Like this: What I do now is add a caption, then cut & paste it into a no-border header table row.  Select the first two rows and set them to "repeat" when the table is broken into multiple pages. But how can I add additional "continue" word at the beginning? Could I use any "field" that indicates page of table, and use "if" to determine whether to show the word?
