suppose have this: namespace { const unsigned my_uint = 100u; const float my_float = 0.f; const char* my_string = "hello world"; } do expected behavior using auto these? presume improvement, i'm not sure in practice. namespace { auto my_uint = 100u; auto my_float = 0.f; auto my_string = "hello world"; } are 2 code examples semantically same? these const automatically? if not, should specify auto const ? auto 's deduction rules equivalent by-value template argument deduction. creating object value entails stripping references , top-level cv-qualifiers initializer. 2 examples not equivalent. in particular, primitive 100u of type unsigned int , that's deduced as. likewise, 0.f of type float . adding const makes sense if variable itself not modified. if want make constants in program, using constexpr might better.

i'm using php , doctrine orm , here's deal: have product table image field , want event check if image exists in assets cloud storage (amazon s3). if file exists if not return file-path of placeholder image. method perform check existence of image resides in s3service class. is there way me tie event entity such every time call like: $product = $this->em->getrepository('entities\product') ->findby(['id' => $productid]); echo $product->getimagepath(); i able default image if file non existent (by calling method in s3service of course). know shouldn't inject services entities cleaner rest of code if can abstract part entity. that's why i'm looking @ event driven kind of solution. have looked @ life cycle events of doctrine entities don't know if there's event executes entity retrieved. question is: event should looking @ or should looking @ solution altogether? it's not practice injectin...

i've built detail view in interface builder showing informations , photos object. because lenght of informations , number of photos vary, nested in uiscrollview . photos shown in uicollectionview , need show contained photos, disabled scrolling , dynamically changing height constraint of uicollectionview function (called when finishing rendering cells): func resizephotoscollectionview() { photoscollectionviewheightconstraint.constant = photoscollectionview.collectionviewlayout.collectionviewcontentsize() } it works great until uicollectionview needs resize (typically device orientation change). trying use uiviewcontrollertransitioncoordinator in function: override func viewwilltransitiontosize(size: cgsize, withtransitioncoordinator coordinator: uiviewcontrollertransitioncoordinator) { coordinator.animatealongsidetransition(nil) { context in self.resizephotoscollectionview() } super.viewwilltransitiontosize(size, withtransitioncoordinator: co...

i using jquery validator validate form fields. below fields: focus @ third field i.e email 2 want focus on first field i.e fax. error message displayed between text both , other static text due alignment shifts here , there. best possible way display messages. in few scenarios error message displayed not focus due user not aware of error. code: var validator = $("#enrollmentform").validate({ errorelement: 'label', errorplacement: function(error, element) { error.insertafter(element); element.focus(); }, }); can provide solution? your own code causing problem you're describing. errorplacement: function (error, element) { error.insertafter(element); element.focus(); // <- line causing whole problem }, by using element.focus within errorplacement , you're telling focus on element being evaluated right when it's been evaluated. if mutiple elements invalid @ once, focus naturally left...

i'm trying make idris function of type (j : nat) -> {auto p : (j < n)} -> fin n convert nat fin n . z case work (and output fz ), i'm trying prove proof of 0 < n sufficient able make fz : fin n . can't work out how this. i'm open making different function, long can convert nat values fin n values (where exist). goal have other function can convert nat mod n value, that, example, 15 : nat mapped 3 : mod 4 . mod type has single constructor, mkmod : fin n -> mod n . after learning lt : nat -> nat -> type , took different approach. started declaration: nattofin : (j : nat) -> {auto p : j `lt` n} -> fin n nattofin {n} j {p} = ?nattofin_rhs_1 . case-splitting on n , on p in n = z case resulted in: nattofin : (j : nat) -> {auto p : j `lt` n} -> fin n nattofin {n = (s k)} j {p = p} = ?nattofin_rhs_2 , proof asking for. there, case-split on j , filled 0 case, leaving: nattofin : (j : nat) -> {auto p : j `l...
