  • function to efficiently check a change of value in a nested hashmap

    - by zcaudate
    the motivation is for checking what has changed in a deeply nest map, kind of like a reverse of update-in. This is a simple example: (def p1 {:a {:a1 :1 :a2 :2} :b {:b1 :1 :b2 :2}}) (def p2 (update-in p1 [:a :a1] (constantly :updated)) ;; => {:a {:a1 :updated :a2 :2} ;; :b {:b1 :1 :b2 :2}} (what-changed? p1 p2) ;; => {:keys [:a :a1] :value :updated) (what-changed? p2 p1) ;; => {:keys [:a :a1] :value :2) I'm hoping that because clojure maps are persistent data-structures, there may be a smart algorithm to figure this out by looking at the underlying structure as opposed to walking through the nested maps and comparing the difference.

  • Recursion function not working properly

    - by jakecar
    I'm having quite a hard time figuring out what's going wrong here: class iterate(): def init(self): self.length=1 def iterated(self, n): if n==1: return self.length elif n%2==0: self.length+=1 self.iterated(n/2) elif n!=1: self.length+=1 self.iterated(3*n+1) For example, x=iterate() x.iterated(5) outputs None. It should output 6 because the length would look like this: 5 -- 16 -- 8 -- 4 -- 2 -- 1 After doing some debugging, I see that the self.length is returned properly but something goes wrong in the recursion. I'm not really sure. Thanks for any help.

  • created persisted computed columns when the user defined scalar function appears to be non-determini

    - by Ralph Shillington
    I have a scalar UDF that I know to be deterministic, however SQL doesn't. Is there a way to declare it as deterministic so that I can then use it in a persisted computed column definition? further clarification: The purpose of this exercise is that I need to harvest out specific values from an XML column on the row. I can't use the value method of the xml column in my computed column definition, but I can use it in a UDF. I know the xpath query in the value method will produce the same output give the same input so while I certainly understand that not all calls to value will be deterministic I want to assert that mine is.

  • AlarmManager Calling Function in Same Class

    - by jsc123
    I am trying to give a LocationClient a two-minute period to connect before calling getLastLocation on it. Initially I implemented this with a Timer (and TimerTask), but because Timers do not work in sleepmode, I would like to translate it to an AlarmManager. However, I am a bit confused as to how to do this, considering an AlarmManager calls another class, whereas I want to remain in the same class and simply delay for a two-minute period. This is how it looks with a Timer. Timer theTimer = new Timer(); theTimer.schedule(new TimerTask() { @Override public void run() { if(checkIfGooglePlay() && checkTime()) { getPostLocation(); stopSelf(); mLocationClient.disconnect(); } } }, TWO_MINUTES);

    Hi, I am trying to use time() to measure various points of my program. http://www.cplusplus.com/reference/clibrary/ctime/time/ What I don't understand is why the values in the before and after are Different? I understanding this is not the best way to profile my program, I just want to see how long does something take. printf ("**MyProgram::before time= %ld\n", time(NULL)); doSomthing(); doSomthingLong(); printf ("**MyProgram::after time= %ld\n", time(NULL)); Thank you.

  • Isn't objective-c function parameter syntax weird? [closed]

    - by Haoest
    Consider the following method: +(void) myMethod:(int)arg1 **argument2**(int)arg2 **argument3**(int) arg3; See how the first argument, unlike the 2nd and 3rd, doesn't have a description, giving it an impression of bad symmetry. Also you would expect the extra typing will provide named argument as you pass it in, but you still have to pass them in the correct order. Can anyone help me make sense of this?

  • arg function not using URL alias

    - by cinqoTimo
    I am running Drupal 6, and I'm using PHP for block visibility. <?php $city = arg(0); $page = arg(1); if ($city == 'tampa' && $page != 'art'){ return 'TRUE'; } else{ return FALSE; } ?> I was having trouble with this block of code, so I decided to insert: <?php print arg(0).arg(1); ?> in my page.tpl.php. What I found was that on some of my pages, arg(0) was showing 'node' when the URL is actually 'tampa', and of course, arg(1) is showing the node ID. However, on other pages, such as my calendar, arg(0) is actually showing 'tampa' instead of 'node'. I have used this a lot in the past, and have never had this problem. Is there a reason why Drupal is disregarding my aliases on certain pages? If so, how can I fix it?

  • Disable link in UIWebView in appearance and function

    - by Peter
    Hello, I wish to disable the href links on a UIWebView. First, I want the look of the link to change so the user doesn't think it is clickable. Second, I want the actual link to not be able to be tapped. I do not want to try webView:shouldStartLoadWithRequest:navigationType: since that not change the appearance of my links. I found this answer: Disabling visible links in UIWebView But the above hasn't worked for me. This is my code: NSString* s=[[NSString alloc] initWithFormat:@"for (a in document.getElementsByTagName(\"a\")) {a.href = \"\";}"]; [myWebView stringByEvaluatingJavaScriptFromString:s]; I've been working on this for hours, any suggestions are appreciated! Thanks!

  • calling a function from a set of overloads depending on the dynamic type of an object

    - by Jasper
    I feel like the answer to this question is really simple, but I really am having trouble finding it. So here goes: Suppose you have the following classes: class Base; class Child : public Base; class Displayer { public: Displayer(Base* element); Displayer(Child* element); } Additionally, I have a Base* object which might point to either an instance of the class Base or an instance of the class Child. Now I want to create a Displayer based on the element pointed to by object, however, I want to pick the right version of the constructor. As I currently have it, this would accomplish just that (I am being a bit fuzzy with my C++ here, but I think this the clearest way) object->createDisplayer(); virtual void Base::createDisplayer() { new Displayer(this); } virtual void Child::createDisplayer() { new Displayer(this); } This works, however, there is a problem with this: Base and Child are part of the application system, while Displayer is part of the GUI system. I want to build the GUI system independently of the Application system, so that it is easy to replace the GUI. This means that Base and Child should not know about Displayer. However, I do not know how I can achieve this without letting the Application classes know about the GUI. Am I missing something very obvious or am I trying something that is not possible?

  • How to use a Visual C++ .Net String type as argument in a function

    - by stefangachter
    Probably this is not a difficult question, but I am always a little bit confused on how to treat String type as an argument in Visual C++. I have the following to functions: void function_1(String ^str_1) { str_1 = gcnew String("Test"); } void function_2() { String ^str_2 = nullptr; function_1(str_2); } After calling function_1, str_2 is still equal to null, but what I want to achieve is that str_2 is equal to Test. So, how can I achieve that the content of str_1 is passed to function_2? Thanks for any advice.

  • Deeper function profiling/emulation

    - by Syntax_Error
    Hello everyone Merry Christmas I need an advice I have the following code: int main() { int k=5000000; int p; int sum=0; for (p=0;p<k;p++) { sum+=p; } return 0; } When I assemble it I get main: pushl %ebp movl %esp, %ebp subl $16, %esp movl $5000000, -4(%ebp) movl $0, -12(%ebp) movl $0, -8(%ebp) jmp .L2 .L3: movl -8(%ebp), %eax addl %eax, -12(%ebp) addl $1, -8(%ebp) .L2: movl -8(%ebp), %eax cmpl -4(%ebp), %eax jl .L3 movl $0, %eax leave ret If I run it through gprof I get that main executed the most, which is quite obvious! Yet I want to go a step further and be able to know if L2, or L3 executed the most. here it is obvious that L3 executed the most. yet is there some kind of profiler, emulator that can give me that data for an entire code?

  • Use a function in a conditions hash

    - by Pierre
    Hi, I'm building a conditions hash to run a query but I'm having a problem with one specific case: conditions2 = ['extract(year from signature_date) = ?', params[:year].to_i] unless params[:year].blank? conditions[:country_id] = COUNTRIES.select{|c| c.geography_id == params[:geographies]} unless params[:geographies].blank? conditions[:category_id] = CATEGORY_CHILDREN[params[:categories].to_i] unless params[:categories].blank? conditions[:country_id] = params[:countries] unless params[:countries].blank? conditions['extract(year from signature_date)'] = params[:year].to_i unless params[:year].blank? But the last line breaks everything, as it gets interpreted as follows: AND ("negotiations"."extract(year from signature_date)" = 2010 Is there a way to avoid that "negotiations"." is prepended to my condition? thank you, P.
