AWS WAF now offers in-line regular expressions - devamazonaws.blogspot.com

AWS WAF extends its regular expression (regex) support, allowing regex patterns to be expressed in-line within a rule statement. Previously, you had to create a regex pattern set, which provides a collection of regex patterns in a rule statement, even if you wanted to use just a single regex pattern in your WAF rule logic. With in-line regex, you can now include a single regex pattern directly inside a WAF rule statement, simplifying how WAF rules are expressed within your web ACL.

[MS] Pulling a single item from a C++ parameter pack by its index, remarks - devamazonaws.blogspot.com

In my earlier discussion of pulling a single item from a C++ parameter pack by its index , I noted that with the Pack Indexing proposal, you would be able to write this to pull an item from a parameter pack while preserving its reference category. template<int index, typename...Args> void example(Args&&... args) { auto&& arg = (Args...[index]&&)args...[index]; using Arg = Args...[index]&&; } Why did I need to apply the (Args...[index]&&) cast ? Why can't I just write this: auto&& arg = args...[index]; or possibly decltype(auto) arg = args...[index]; Well, when you write the name of a variable, the result is an lvalue reference, even if the variable is an rvalue reference . Watch: struct S { S(S&); // construct from lvalue S(S&&); // construct from rvalue }; void whathappens(S&& s) { S t = s; // which will it use? } Try it out in your favorite compiler. This code construc...

[MS] Debugger breakpoints are usually implemented by patching the in-memory copy of the code - devamazonaws.blogspot.com

In practice, when you set a code breakpoint in the debugger, the debugger replaces the instruction at that location with a breakpoint instruction.¹ When execution reaches that instruction, it will encounter the breakpoint instruction and break into the debugger. When the program has been stopped in the debugger, what happens next can vary from debugger to debugger. Some debuggers remove all their breakpoints when the program stops, and then restore the breakpoints when the program resumes. Other debuggers leave the breakpoints in place even when the program is stopped. In both cases, if you inspect the memory in the debugger, you will see the original unpatched code. In the first case, it's because the code really is unpatched; the breakpoint instructions are removed. In the second case, it's because the debugger is lying to you and showing you the original bytes even though they aren't what are in memory right now. Most of the time, this deception is insignificant. Eve...
