i have pilot django project installed on heroku using free tier , free postgres database. due size limitation on heroku, moved database amazon rds free tier offers lot more space , no row limit. after move notice slow performance in django app! there way reconfigure setup make application/database go faster? if it's "free tier" of rds, using small database (in terms of cpu , memory) shouldn't come surprise slow. specifically, free tier t2.micro, has 1 virtual cpu , 1gb of memory. also, storage type (magnetic, ssd, provisioned iops) may make substantial difference. can observe disk stats in cloudwatch rds instance see if that's problem.

i new enums in java , confused why code compiles fine enum scale5 { good(), better(), best(); static scale5 s=good; } but code fails: enum scale5 { good(), better(), best(); scale5 s=good; } and error : illegal reference static field initializer. dont understand reason.i relatively inexperienced in enums please dump down me.thanks lot! the question asked here cannot refer static enum field within initializer? exact opposite of have asked.in case declaring s static compiles code fine. think of enum this: public final class scale5 { public static final scale5 = new scale5(); public static final scale5 better = new scale5(); public static final scale5 best = new scale5(); static scale5 s = good;//works because initialized first; scale5 ss = good;//doesn't work because in order initialize good, //ss must assigned object not yet initialized; }

given 2 pyobject* s, how can compare them in c api? i thought of a == b @ first, it's incorrect since compare pointer , not object. i'm looking a == b (not a b ) python equivalent in python c api. you looking pyobject_richcompare function: pyobject *result = pyobject_richcompare(a, b, py_eq); from documentation : pyobject* pyobject_richcompare(pyobject *o1, pyobject *o2, int opid) return value: new reference. compare values of o1 , o2 using operation specified opid , must 1 of py_lt , py_le , py_eq , py_ne , py_gt , or py_ge , corresponding < , <= , == , != , > , or >= respectively. equivalent of python expression o1 op o2 , op operator corresponding opid . returns value of comparison on success, or null on failure. you might interested in pyobject_richcomparebool function , same pyobject_richcompare returns integer rather pyobject * . specifically, 1 returned true, 0 false, , -1 error.

theoretically, should 65,535 x 65,535 given have enough memory, 17gb. however, creating .net 4.5 console application test out, throws system.argumentexception: parameter not valid. the application built 64bit platform. running on 64bit platform 32gb of memory. maximum resolution i've been able 22,000 x 22,000 pixels. i not find documentation on this. and odd behavior @ 22,000 x 22,000 pixels, doesn't work. works, , throws exception. make me think it's related contiguous memory allocation, there 30gb of free memory. does have experience this? , if wanted work say, 100,000 x 100,000 pixel image , larger, best way besides implementing own bitmap? edit: problem isn't .net maximum object size. can overcome targeting 64bit platforms, , setting gcallowverylargeobjects flag in application config. in way, can application consume on 15gb of memory single array of integers. far, answer seems lie in underlying implementation of gdi+, how around it? this gdi

ok, here's programming/physics puzzle in, let's java (although doesn't matter - consistency, use java). i have array of doubles each element represents successive derivates of object's position. so: d[0] // position d[1] // velocity d[2] // accelleration etc ... there @ least 1 , potentially number of elements (but in practice, not more 5). elements beyond end of array assumed zero. we have double t time. so if d.length 3 specifically: d[0] += d[1] * t + d[2] * t * t / 2 d[1] += d[2] * t but how can write iterative solution (no recursion!) update of elements of array time t length of a? votes should awarded efficiency , conciseness. edit: laws of motion on physics pages of site, each term has form: power(t,n) / factorial(n) so next term of first equation d[3] * t*t*t / 6 if not familiar these equations, please don't ask me explain. a test case: final static double[] d = { 5.0, 4.0, 3.0, 2.0, 1.0 }; double t = 10.0 should give:

our project in agile environment requirements keep changing every sprint. annoying part unit tests keep failing due requirement change. , takes longer fix , maintain them. do have suggestions in general, better approach situation? in advance. this common issue, , related how committed maintaining unit tests. you mention tests break when requirements change, i'm assuming means update code meet changing requirements, you're not updating tests @ same time. a development approach committed benefits of repeatable unit tests update unit test code @ same time code changes made. if don't, how re-test code changes, or how can prove code changes work? if you're not committed maintaining unit tests @ same time code changes, might embrace fact , throw them away code changes, because @ point, you're finding out, tests become useless. it's common problem , 1 many projects struggle with. tests written 1 time test code when written, after point discarded,

i have script checks bools through if statements , executes code. trying make that: if variable true, check if b true , execute code if variable false, execute same code mentioned before a simplified version of have this: if a: if b: print('foo') else: print('foo') is there better way doesn't require me write print('foo') twice? if not or (a , b): print('foo') let's talk step step: when print('foo') executed? when a , b both true . when else executed, else ? opposite of previous if not a . finally wish display 'foo' in 1 case or other. edit: alternatively, simplifying logic equation: note: you might want avoid unless know doing! clarity way better shortness. trust advice! i've been through there! ;) if not or b: print('foo') because if not a not true , a must true (the second part of or ), a , b can simplified in b (because know fact a true

i updating custom cms codeigniter laravel. uses custom masks (currently in single curly brackets) allows user entered content dynamically updated values entered elsewhere. codeigniter gave neat way of doing the page parser passed associative array (such favouritefruit=>'apple') - replace relevant masks on entire page prior output. meant masks used anywhere. trying find neat way of doing in laravel 4.2. ->render() view variable , str_replace prior controller returning it, wondering if there 'native' way perhaps using blade. in short trying run mask replacement twice on same data. thanks! a string replace on whole view pretty easy actually. call render() , view string: $view = view::make('view.name')->render(); $view = str_replace('{mask}', 'value', $view); return $view;

when use java's maven , gradle, can download source code artifacts. way can inspect source code , debug it. useful, libraries poor documentation. i'm using xamarin studio , nuget packages , xamarin components. for example, add sqlite-net component project , able browse source files. you try .net reflector. remember had while ago , allowed me see source of libraries. can't remember if there special libraries (debug mode or something).

i have 2 radio buttons have changed clickable images using label , working great. problem is, when 1 label checked, second not unchecked. here code of 2 functions : var $radiobuttons = $('input[value="2"]'); $radiobuttons.click(function() { $radiobuttons.each(function() { $(this).parent().parent().toggleclass('checked11', this.checked); }); }); var $2radiobuttons = $('input[value="5"]'); $2radiobuttons.click(function() { $2radiobuttons.each(function() { $(this).parent().parent().toggleclass('checked12', this.checked); }); }); you need interlink radio buttons. giving them name attribute. in example i've added 2 sets of radio buttons. changed selector of jquery function select on name attribute. name attribute can same multiple elements in contradiction id attribute must unique throughout entire document. can use advantage when selecting elements usi

i know has been asked before answers given did not work me , scenario in case different. i starting evaluate nanogallery, looks requirement run slideshow of inline image references. want run slideshow link rather having display set of thumbnails , clicking/tapping on 1 start slideshow. doesn't seem me particularly unusual requirement, large slideshow set of thumbnails occupy far space on screen. my html simply: <a id="startlink" href="javascript:void(0)" style="margin-bottom: 40px;">run slide show</a> <div id="nanogallery"> <a id="first" href=... data-ngdesc=... /> ... so have tried: $(document).ready(function () { $("#startlink").click(function (e) { $("#nanogallery").nanogallery({ slideshowautostart: true, ... }); $("#first").trigger("click"); }); }); i have tried various alternatives, including

i'm trying assess fastest solution sharing state across single-writer, single-reader scenario, reader consumes latest value of state variable assigned writer . shared state can of managed type (i.e. reference or value types). ideally synchronization solution work fast naive non-synchronized solution possible, since method used both single-threaded , multi-threaded scenarios potentially thousands of times. the order of read/writes shouldn't matter, long reader receives latest value within time frame (i.e. reader ever read, never modify, update timing doesn't matter long doesn't receive future value before older value...) naive solution, no locking: var memory = default(int); var reader = task.run(() => { while (true) { func(memory); } }); var writer = task.run(() => { while (true) { memory = datetime.now.ticks; } }); what issues naive solution? i've come these far: no guarantee reader sees latest valu

i'm trying operations on matrices using matrix library named, "eigen library". i've 50 x 100000 matrix in size , want find covariance matrix. so, can built_in function to find covariance matrix? c++ sample code: #include "eigen/core" #include "eigen/dense" using namespace eigen; using namespace std; int main() { matrixxf my_matrx = matrixxf::random(50,100000); //now, want find function find covariance matrix of "my_matrx", below: matrixxf my_cov_matrix = any_function(my_matrx); }

why able access enum constant hot directly in code below: enum spice_degree { mild, medium, hot, suicide; } class switchingfun { public static void main(string[] args) { spice_degree spicedegree = spice_degree.hot; //unable access hot directly switch (spicedegree) { case hot: //able access hot directly here system.out.println("have fun!"); } } } it's way language defined - when case labels enum values, means switch expression must enum of type, specifying enum type everywhere redundant. from jls 14.11 : every case label has case constant, either constant expression or name of enum constant. and if type of switch statement's expression enum type, every case constant associated switch statement must enum constant of type.

all divs used web page layout specified own widths , heights, heights different widths same: 1000px. media query @media screen , (max-width: 1000px) { #container { width: 100%; } #desktop_ul { width: 100%; } .desktop_li { margin: 0 0.5%; } #article { width: 100%; } #footer { width: 100%; } } is supposed make these divs transform percents when browser window shrunk down 1000px or less, when shrink down window, horizontal scroll bar brief second, or 20px , disappears once reach 980px. why doesn't media query activate @ 1000px, why have shrink down window 980px activate?
