Specman macro to do set subtraction with int_range_list objects |

I work with a bunch of sets in order to generate constrained random traffic, but I want to be able to call a Specman macro that computes the complement of a set with syntax like:
COMPLEMENT begin

complmenting_set=[2..3,27..30]

If there is a cookie set for a subdomain, metric.foo.com, is there a way for me to delete the metric.foo.com cookie on a request to www.foo.com? The browser (at least Firefox) seems to ignore a Set-Cookie with a domain of metric.foo.com. |

Shocking, but almost every response here included some form of CAPTCHA. The OP wanted something different, I guess maybe he wanted something that actually works, and maybe even solves the real problem.

The drive where the script is : ~d0

It is a condition you know to always be true at a particular place in your logic and can check for when debugging to work out what has gone wrong. |
`%~d0` gives you the drive letter of argument 0 (the script name), `%~p0` the path. |
I have used Ironspeed extensively for the past two years for most of our ASP.NET forms over data projects.

I usually view them more in terms of algorithms or structures.

Use [str_replace()][1]:
$text = str_replace('http://stackoverflow.com/xyz1', 'http://yahoo.com/abc1', $text);
That will replace the first URL with the second URL in $text.

The only layout manager that I have found, that I actually **like** is the [Relative Layout Manager][1].

GCC is smarter than most of us in producing machine code from our source code; however, I shiver if it was smarter than us in re-arranging our structs, since it's data that e.g. can be written to a file.

You may also want to consider the [csv](http://docs.python.org/lib/module-csv.html) module. I haven't tried it, but it looks like your input data is closer to CSV than to shell syntax (which is what shlex parses). |

I'd avoid using toString() on objects other than the basic types. toString() may not display anything useful. It may iterate over all the member variables and print them out.

No standard and portable way.
Some implementations provide [itoa()](http://en.wikipedia.org/wiki/Itoa), but it's not going to be in most, and it has a somewhat crummy interface. But the code is behind the link and should let you implement your own formatter pretty easily. |

An invariant is more "conceptual" than a variable. In general, it's a property of the program state that is always true. A function or method that ensures that the invariant holds is said to maintain the invariant.
For instance, a binary search tree might have the invariant that for every node, the key of the node's... |

MyISAM tables already store the row count, so "SELECT COUNT(*) FROM table" on a MyISAM table simply reads that value. It doesn't scan the table or the index(es). So, it's just as fast or faster than reading the value from a different table. |
Just to be clear, the index is on the (presumably varchar or nvarchar) field in the table, correct? Not the PK? |

According to one of our senior developers VS2008 features extended support for multicore compilation ( file-wise instead of project-wise I'm told ), so there might be a reasonable performance optimization for your project. |
Generally source control systems merge on a line-by-line basis by default. I have found that merging Python code is no different from merging any other source code that is reasonably indented. If one programmer wraps a block of code in an `if` statement (indenting the whole block), and another programmer modifies somet... |
To add to the previous answers, I would recommand also the obvious (but they should be made explicit) advices:

- create immediately a label (or tag in SVN), once the import is done and 'checked' (like 'does it compile ?'... |
My first thought is that the second version might be infinitessimally faster than the first, because no reference is pushed on the stack as an argument. However, this would be very compiler-dependant, and depends for instance on whether the compiler performs Named Return Value Optimization or not.

If the function is inlined at compile time, the cost of the function becomes equivelant to 0.
0 of course being, what you would have gotten by not having a function call, ie: inlined it yourself.
This of course sounds excessively obvious when I write it like that.
