  • Indexing one-dimensional numpy.array as matrix

    - by Alain
    I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

    Binary search follows Divide and Conquer method where as linear Search doesn't follw.The time complexity of Binary Search in O(log n) but incase of linear search the time complexity is O(n). Thats way Binary search is having bettr prior than linear search. But it is true when the list of items is large incase of smaller list linear is best(i.e.- it is only when the Best Case concern)

    - by Pindatjuh
    Is there a benchmark available how much relative time each instruction costs in a single-thread, average-case scenario (either with or without JIT compiler), for the JVM (any version) by Sun? If there is not a benchmark already available, how can I get this information? E.g.: TIME iload_1 1 iadd 12 getfield 40 etc. Where getfield is equivalent to 40 iload_1 instructions.

    - by meo
    Given is a form that is followed by a confirmation page where you have to confirm you entered data of previous form. Now if the user refreshes this recapitulation page, the data form the previous form reposts. Is there a way to prevent that in JavaScript? I know its not a ideal solution, it should happen on the server side. But i have no choice in this case.

  • can I have an abstract base class with the key attribute being generic

    - by Greg
    Hi, I want to create a re-usable library. I was going to use extension methods however I run into some issues in some cases for the client to have to specify in the calling method the types. QUESTION - If I use an abstract base class as the basis, can I specify an attribute/property in the class to be generic (e.g. the key property might be an 'int' in one case, or a 'string' in another)?

  • Python - How is this snippet working?

    - by orokusaki
    For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

  • Tracking SVN changes through multiple merges

    - by Paul D.
    At work we use a branching strategy where all changes start off in a development branch, then subsequently make their way through one or more integration branches, and finally end up in a release branch. Occasionally (more often than I'd like) I find myself needing to figure out where a particular change originated (which development branch). In this case I have to spend a considerable amount of time playing detective to trace a change backwards through 2-3 merges. Am I missing an easy way to do this?

  • Meteor Deps - Running a Client Side Func

    - by Andrew Plummer
    I'm struggling to get a handle on Meteor deps, in order to be specific my use case is: 2) When collection is changed, I want to run a jQuery function on the client side I think deps are what I'm looking for, but at the moment I have only just used: Template.templateName.set () -> return Set.find({}) ...in terms of reactivity. A solution which simply console.log's the collection each time it is changed would be more that enough.

  • Determine opencore or stagefright framework for mediaplayer?

    - by user415422
    I need to determine if a mediaplayer is using the opencore media framework, so that I can disable seeking for my streams. The opencore framework appears to fail silently with seeking, which I am having a hard time believing they allowed into production, but that seems the case nonetheless. I wish it were as simple as determining their SDK version, but droid phones that have api 8 seem to use opencore still, so doesn't seem to be a good option. Any ideas?

  • Does the compiler optimize the function parameters passed by value?

    - by Naveen
    Lets say I have a function where the parameter is passed by value instead of const-reference. Further, lets assume that only the value is used inside the function i.e. the function doesn't try to modify it. In that case will the compiler will be able to figure out that it can pass the value by const-reference (for performance reasons) and generate the code accordingly? Is there any compiler which does that?

  • How could I pass the float number by value in obj-c?

    - by user313439
    - (void)applicationDidFinishLaunching:(UIApplication *)application{ // Override point for customization after application launch [window makeKeyAndVisible]; [self printFloat:1.3f]; } - (void)printFloat:(float)f { NSLog(@"%f",f); } I passed the "1.3f" to printFloat, but it was the wrong value (in this case, -2.000000) after "f" received. And there is a warning that "AppDelegate may not respond to -printFloat:" Where did I get it wrong? Thanks.

  • CSS: right wrapper dropping off the end of the page

    - by user310606
    I have an issue with a site I am working on where the right wrapper keeps dropping down below the site. Obviously I want it to stay on the right hand side. I've coded up a test case which shows my issue (I think) and I'm wondering if there is a better way to do things. The website url is http://www.musicworkshop.co.nz/ Below is the test case which (I think) is the cause of my issue, however it may not be. The pink box drops down if it does not fit within the page width. Is there a better way to do this? John <html> <head> <title> Test page </title> <link rel="stylesheet" href="test.css" type="text/css" /> </head> <body> <div id="superbox"> <div id="box1"> </div> <div id="box2"> </div> <div id="box3"> </div> <div id="box4"> </div> <div id="box5"> </div> <div id="box6"> </div> </div> </body> </html> #outsidebox{ width: 100%; } #superbox{ width: 1000px; height: 100px; margin: 0 auto; } #box1{ height: 100px; width: 200px; background: red; float: left; } #box2{ height: 100px; width: 200px; background: yellow; float: left; } #box3{ height: 100px; width: 200px; background: blue; float: left; } #box4{ height: 100px; width: 200px; background: green; float: left; } #box5{ height: 100px; width: 200px; background: grey; float: left; } #box6{ height: 100px; width: 200px; background: pink; float: left; }

  • Why can operator-> be overloaded manually?

    - by FredOverflow
    Wouldn't it make sense if p->m was just syntactic sugar for (*p).m? Essentially, every operator-> that I have ever written could have been implemented as follows: Foo::Foo* operator->() { return &**this; } Is there any case where I would want p->m to mean something else than (*p).m?
