Just what is a regular expression, anyway?
Take the tutorial to get the long answer. The short answer is that a regular expression
is a compact way of describing complex patterns in texts. You can use them to search
for patterns and, once found, to modify the patterns in complex ways. You can also use
them to launch programmatic actions that depend on patterns.
A tongue-in-cheek comment by programmers is worth thinking about: "Sometimes you
have a programming problem and it seems like the best solution is to use regular
expressions now you have two problems." Regular expressions are amazingly
powerful and deeply expressive. That is the very reason writing them is just as
error-prone as writing any other complex programming code. It is always better to
solve a genuinely simple problem in a simple way when you go beyond simple, think
about regular expressions.

多項式曲線擬合 任意介數 Purpose - Least-squares curve fit of arbitrary order
working in C++ Builder 2007 as a template class,
using vector<FloatType> parameters.
Added a method to handle some EMathError exceptions.
If do NOT want to use this just call PolyFit2 directly.
usage: Call PolyFit by something like this.
CPolyFit<double> PolyFitObj
double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A)
where X and Y are vectors of doubles which must have the same size and
A is a vector of doubles which must be the same size as the number of
coefficients required.
returns: The correlation coefficient or -1 on failure.
produces: A vector (A) which holds the coefficients.
Siproxd is a proxy/masquerading daemon for the SIP protocol.
It handles registrations of SIP clients on a private IP network
and performs rewriting of the SIP message bodies to make SIP
connections work via an masquerading firewall (NAT).
It allows SIP software clients (like kphone, linphone) or SIP
hardware clients (Voice over IP phones which are SIP-compatible,
such as those from Cisco, Grandstream or Snom) to work behind
an IP masquerading firewall or NAT router
Please unzip the file and make the file under linux with version 2.6 or above. The function is just like the utility traceroute in linux or tracert in windows.
These listed libraries are written in WTL. But it s really hard to mix both MFC & WTL together. Obviously, it s not reasonable to ask a developer or a team to giving up MFC and move to the WTL world just because there were some great controls or visual Frameworks written in WTL (there are many things that should be considered especially in a company with hundreds of developers like the company I work for). Unfortunately, there was no such good and free visual Framework in MFC until now. Whatever difficulties there are, I still desire to be able to use them and now my effort is here to be shared with you.

Expert C Programming: Deep C Secrets
By Peter van der Linden.
Have you ever noticed that there are plenty of C books with suggestive names like C Traps and
Pitfalls, or The C Puzzle Book, or Obfuscated C and Other Mysteries, but other programming
languages don t have books like that? There s a very good reason for this!
New training algorithm for linear classification SVMs that can be much faster than SVMlight for large datasets. It also lets you direcly optimize multivariate performance measures like F1-Score, ROC-Area, and the Precision/Recall Break-Even Point.
Excellent Bootloader with a lot of features for arm, can be used for homebrew applications or for learning how a bootloader works, it has support for networking and yet has a very small size. support for filesystems, flash disk, flash, cf etc present. ideal when you would like get ur board up and running quickly.
