Essentially, I want to know how to run 2 (or more) find commands in one - an "or" search rather than an "and":  find . -name "*.pem" find . -name "*.crt"
How is it possible to use the GNU find command to match several file types at a time (one search command)?  The man page says:  -type c     File is of type c:     b      block (buffered) special     c      character (unbuffered) special     d      directory     p      named pipe (FIFO)     f      regular file     l      symbolic link; this is never true if the -L option or the -follow            option  is in  effect,  unless  the  symbolic link is broken.  If            you want to search for symbolic links when -L is in effect, use            -xtype.     s      socket     D      door (Solaris)   and I want to search for files (f) and symbolic links (l) and pipe it to another process. How can I search for both at the same time?  I have tried  find -type fl | … find -type f -type l | … find -xtype f -type l | …   I know a workaround would be to use a subshell  (find -type f; find -type l) | …   but I just want to know if it is possible.
How deterministic is floating point inaccuracy? I've been trying to install 12.04 for a while now, I'm running on Windows 7 and I already made the partition (it's dynamic). I've tried booting from a disc and also the Windows installer. I haven't tried used any repair-boot programs or anything. Every time I tried to load from either, I get an error:  command=C:\windows\sysnative\bcdedit.exe /set {03f9077f-661f-11e1-845a-d08b36406c3d} device partition=U;  retval=1  stderr=An error has occured setting the element data. The request isn't supported  stdout=   Then after that, it makes a log file with information that I don't understand.  If it is simply due to the fact of it being a dynamic partition, someone please help. If it is more extensive, anyone with details on possible solutions or definite ones please express them. Where can I ask questions regarding Electronics? I am currently doing some electronics and microcontroller programming, and I have a couple of questions to ask the people here.    Most of the questions are regarding wiring on breadboards and components.    On which of the websites (Stack Overflow, Server Fault, or Super User) should I ask these particular questions? I understand the reasoning behind the fairly narrow textwidth in a default LaTeX article. 60-80 characters per line and all that. However, I am preparing a document that features many lengthy equations, and it seems silly to me to restrict the equations to fit into the same margins as the text when there's all that whitespace going unused on either side.  I'd like to have equations which are wider than the textwidth do the obvious thing, that is, continue to be centered on the page just like all the other equations, and simply extend into both the left and right margin equally. My equations are unnumbered, so there's no concern about where to put equation numbers.  How might I go about implementing this? Android and getting a view with id cast as a string What is the difference between CentOS "DVD" vs "Everything" ISOs For all $X \geq 1$,$\sum\limits_{1 \leq n \leq X} \mu(n) \left[\frac{X}{n}\right] = 1.$ I'm currently sitting with the following number theory problem:  Prove that for all $X \geq 1$, $$\sum_{1 \leq n \leq X} \mu(n) \left[\frac{X}{n}\right] = 1.$$  A few ideas I have tried: Using that $[x]=x - \{x\}$ which I couldn't make out to bring anything. Switching around on the summation variables, like $$\sum_{d \leq N} \mu(d) f\left( \frac{n}{d} \right) = \sum_{d \leq N} \mu \left( \frac{d}{n} \right) f(d)$$ but that didn't seem to bring anything.  I tried writing out the first few terms, which give $$\mu(1) [X] - \left[\frac{X}{2}\right] - \left[\frac{X}{3}\right] - \left[\frac{X}{5}\right] + \left[\frac{X}{6}\right] - \left[\frac{X}{7}\right] - \left[\frac{X}{8}\right]$$ but I can't seem to find a system where it simply reduces to one!

When should I use mmap for file access? POSIX environments provide at least two ways of accessing files.  There's the standard system calls open(), read(), write(), and friends, but there's also the option of using mmap() to map the file into virtual memory.  When is it preferable to use one over the other?  What're their individual advantages that merit including two interfaces?

I have loads of space on it and it the speeds are great. Where are the necessary places to be appended with % to remove unwanted spaces? I have  experience where empty spaces cause unwanted effects. It is not easy to trace the cause of these unwanted effects.
