but why store it as the serialized xml? normalize that poo poo

usually yes, but once in a while you can't normalize it and a serialized object column is the next best option. the alternatives are so much worse

normalized data in atomic columns > serialized object column > entity-attribute-value table > half-assed homemade string concatenation and conversion mess > unspeakable horror that most closely resembles a stack-based Polish calculator for logic rules in the form of indexed sql rows

why would you store serialized data in your database at all?

sometimes you are gonna be storing full xml documents, and there are three places you can do that

the filesystem
an awful nosql/object store
a real database

storing them in the database has the advantage that now in addition to simple search/retrieval, you can also reference xml data from regular old queries that primarily access fully normalised data

it's not an ideal situation but it beats the hell out of the other two options

I'd be down for a new generation of web browsers that are all about static sites with no JS and very limited design capabilities. Bring back document-based web.

good use of SPA - being able to manipulate and maintain page state while also loading new data. like to keep scroll position or user input. e.g. the web app for myfitnesspal would be better with more SPA features. there are forms that include paginated lists I might want to flip through for reference. but if I do I'll lose what I've entered so far in the form on the page.

bad use of SPA - everything else on the web

you jcan make a non sucky SPA where the users cant tell its a SPA. so you just get the pure advantages of partial page updates, async form validation, getting to use react for both partial & full page updates & server side rendering with shared code (rather than some janky combo of jquery and a server side template lang), etc.

ajax was supposed to (and still can) make the web a more responsive ui. its just that spa frameworks dont come out of the box forcing you to do the right thing, so """web""" """"""developers"""""""" half rear end things like handling of all possible async states, proper url routing that doesnt break nav controls and linking, not making dynamic forms janky, etc. you have to come up with all this stuff on your own.
web devs just seem more concerned with coming up with 1000 libraries to not have to type as much (stylus, jade, pug, coffeescript)

update your software OP

More seriously, does -Wconversion catch that on your g++? I would imagine it should, but I could see '\0' implicitly being given a pointer type to begin with and thus not being "converted".

not as big but a huge usability improvement. template parameter deduction has been finally extended to classes, poo poo like make_tuple or make_pair is no longer necessary. tuple expansion is native, no longer a library function. you could already map variadic template argument lists, now you can also reduce with any binary operator. the stl finally has long overdue essentials like optional, any, variant, string_view, gcd/lcm and the filesystem library. parallelized variants of algorithms

some wunderkind on the c++ committee thought that "ptr == 0" looked more aesthetically pleasing than "ptr == NULL"

then everybody else belatedly realized that this person is a loving moron so now there's a built in type called nullptr_t or something

except that the == 0 thing still works and of course '\0' is equivalent to 0

c++ is such a trash fire

lol, no they didnt. its because int* x = NULL doesn't work when you #define NULL (void*)0 in C++, but does in C because you can assign any void* implicitly in C and in C++ you need to explicitly cast it.

I wonder why it took them so long to come up with nullptr. if you wrote a smart pointer class and you wanted to make NULL assignable to it, guess how you had to do it?

C++ code:

fart_ptr& operator=(int) { // ayeeep
    reset();
    return *this;
}

except now you can assign any int to it, variable or constant, zero or not :bravo:

Okay I'm reading through the C++17 changes and a bunch of these are very neat. My favorite so far (that hackbunny didn't mention) is attributes, which I had previously only run into in Rust. Being able to mark intentional switch-statement fallthrough as [[fallthrough]] (to suppress warnings when this is intentional) and being able to mark functions as [[nodiscard]] (to ensure that their return is used) are excellent.
