errata

I use JLS extensively both as a learning and teaching resource, but I've noticed that there are some errors in it. There's the simple typos (e.g. JLS 5.1.4 "convesions"), but there's also some that I consider quite serious errors. For example, JLS 18.1 The Grammar of the Java Programming Language is supposed to be the authoritative reference for the grammar of the Java language, but it contains a production rule that never gets used! (e.g. MoreStatementExpressions ). Surely this is a sign of more serious errors in other parts of the given grammar, right? So is there an errata for the 3rd

G’day All, has anyone purchased the ALPHA of Apress Pro Asp.net MVC Framework 3 and created the SportsStore? I can’t for the life of me edit products and have the DB update successfully? No errors are displayed and unit tests all function, but no successful ‘edit’ i.e. I change some details, click save, it reports successful – I then check the results, and nothing has happened? Did anyone else find this when working through the SportsStore? Any advice will be greatly appreciated. Cheers. The state of the EF object needs to be updated before saving. public void SaveProduct(Product product) { if

In the book, "Understanding and Using C Pointers" by Richard Reese it says on page 85, int vector[5] = {1, 2, 3, 4, 5}; The code generated by vector[i] is different from the code generated by *(vector+i) . The notation vector[i] generates machine code that starts at location vector , moves i positions from this location, and uses its content. The notation *(vector+i) generates machine code that starts at location vector , adds i to the address, and then uses the contents at that address. While the result is the same, the generated machine code is different. This difference is rarely of

In this blog entry by Andrey Karpov entitled, "About size_t and ptrdiff_t " he shows an example, for (ptrdiff_t i = 0; i < n; i++) a[i] = 0; However, I'm not sure if that's right, it seems that should be for (size_t i = 0; i < n; i++) a[i] = 0; Is this correct? I know we should also likely be using something like memset , but let's avoid that entirely. I'm only asking about the type Pascal Cuoq In a blog post , I argue that you should always refrain from allocating memory blocks larger than PTRDIFF_MAX (*), because doing so will make compilers such as Clang and GCC generate nonsensical code
