fart simpson posted:i know, i just want an excuse to try erlang for something https://github.com/ninenines/cowboy/tree/master/examples/static_world is a demo of using cowboy to do that. Unless you really really love makefiles and want to use erlang.mk (the cowboy's author homebrew build system framework made out of makefiles), I recommend you use rebar3 instead (which is the homebrew build system I work on)

Usually you can tell a lot earlier with Valgrind.

update re: butts.mvc i refactores to remove the interface and just piled the properties i needed to bind into the base class regardless of whether the inheritors needed them or not, but i kept the inheritor classes which then have their own methods attached for population so i can still have class specific cshtml editor templates and don't have to maintain one mega editor file. now all i need to do is figure out how to implement lists of checkboxes in razor without it failing to bind. Ps. It it also total bullshit that .net mvc will let you reference an editor via @html.editorfor but not actually error when no editor exists or when you have an editor for that model but the cshtml filename doesn't match the classname. I spent a good hour trying to work out why my breakpoints were invald because there was a silent validation fail on this poo poo.

I think you can manually specify a template for an editor if the class name doesn't match the template name but idr. also if you have a bunch of unused things in ur model u may be overcomplicating something, but if it works it works I guess.

im making some assumptions, but there are maybe a few other ways you could do it. Lets assume we fix the model and have a base butt interface or abstract class and then individual butt types for each butt type in your db. If you have an IEnumerable<ButtBase> or IEnumerable<IButt> in your model you could, inside your view, pick different partial views based on the actual concrete class. The problem here is what happens when the butts are changed and submitted? The default binder wont know how to bind buttbase (and in fact it think it will tell you to get bent if its an interface or abstract class). You could then create a custom model binder that would handle the logic of determining the butt type and desterilizing it from the form input. This would give you very nice clean views and models at the expense of the extra dev time on the custom binder. a really gross other way to do it would be to have in your model a list for each butt type. so IEnumerable<BigButt> BigButts and IEnumerable<LittleButt> LittleButts. then in your view you essentially enumerate all these collections and display them in a way that's transparent to the user. If they can add new butts to the input form you make sure they get added with the input name of the proper butt type list. This way is probably the least effort if you've never done custom model binding before (it really isn't that hard) and the tradeoff is a gross view

Shaggar posted:im making some assumptions, but there are maybe a few other ways you could do it. yeah i've fortunately avoided having list for each type, that wouldn't really work anyway because the mixed types have to be ordered in a specific way. I think I could do it by using a list of <Butts> where Butts can contain ButtType1, ButtType2 etc. but even then a given instance of Butts will have properties that can never be filled so it hasn't really made anything neater in that sense. a custom binder for the interface would probably work if I bound the enum that defines ButtType and seems to have been done before but tbh i think what I'm trying to do is a $50 solution to a $0.50 problem and is putting purity of model over readability of code. Edit: hmmm, on looking into it custom binders might not actually be as bad as I thought because I can add the type enum to the model so potentially all that my binder needs to do is look at that attribute to know what type of class to bind to, but that might be optimistic on my part. edit 2: holy gently caress this person is doing almost exactly what I am i.e. taking a clusterfuck of a form (though not 100 pages of a word form in my case lol wtf) and using an interface to represent the different types of form item that can exist under it, then using a bound "section type" to force the binder to create an instance of the appropriate concrete class. god drat, i knew i couldn't have been the only person that thought that interfaces should be usable in mvc for this exact case.

I have a dumb math question because I'm terrible at both math and programming. I'm doing cryptopals and I'm on challenge 36: http://cryptopals.com/sets/5/challenges/36/ The part I'm having trouble with is that ruby is bitching that my 'u' values and 'x' values are too large to do exponentiation on. With the previous Diffie Hellman challenges this wasn't an issue because I was using modexp. However in the lines below I don't see how I can simplify them because I need to give the output of exponents to my modexp function. There might be some algebraic way I can use modexp to avoid the issue, but I'm too dumb to know how to do it or if it's even possible. quote:Generate S = (B - k * g**x)**(a + u * x) % N

Check out http://math2.org/math/algebra/exponents.htm In particular, y = B - k * g**x Then the first expression is the same as y**a * y**(u*x) % N And y**a * (y**u)**x % N And (y**a % N) * (y**u % N) **x % N Note that you CAN'T just mod N the exponent. See here for more details: http://www.dragonwins.com/domains/getteched/crypto/modular_arithmetic_intro.htm#Modular Exponentiation I know it's not complete (God I hate typing maths on my phone) but it should be enough to get you started. When I get home from work I'll give you a better answer if nobody else has. Honestly the math thread in S, A & L might be a better fit for this question as crypto often passes the nonexistent line from programming to pure maths.

it's 11pm on a Friday night and instead of being drunk I have been fixing mvc binding to an interface, turns out I removed one important line in my lazy C&P of the custom binder so nesting didn't work properly. that said, even though its documentation is basically godawful and things that should logically work out of the box a)don't and b) don't always throw errors when they don't*, .net mvc owns bones *ffs if you're going to make your syntax 100% reliant on filenames matching class names you should at least show an error when @Html.EditorFor points to nothing because you refactored the class but didn't change the template name, instead you just get a "breakpoint won't be hit, symbols not loaded error" which is the Visual Studio equivalent of "gently caress you I hope you enjoy spending an hour loving with settings and running rebuilds to work out why you can't debug dipshit"
