  • In Java, how do you parse through a single word string?

    - by Fraz
    I'm trying to parse though a string made up of a single word. How would you go about assigning the last letter of the word to a variable? I was thinking of using the Scanner class to parse the word and make each letter an element in an array but it seems Scanner.next() only goes through whole words and not the individual letters. Any help?

  • Python: How can I override one module in a package with a modified version that lives outside the pa

    - by zlovelady
    I would like to update one module in a python package with my own version of the module, with the following conditions: I want my updated module to live outside of the original package (either because I don't have access to the package source, or because I want to keep my local modifications in a separate repo, etc). I want import statements that refer to original package/module to resolve to my local module Here's an example of what I'd like to do using specifics from django, because that's where this problem has arisen for me: Say this is my project structure django/ ... the original, unadulterated django package ... local_django/ conf/ settings.py myproject/ __init__.py myapp/ myfile.py And then in myfile.py # These imports should fetch modules from the original django package from django import models from django.core.urlresolvers import reverse # I would like this following import statement to grab a custom version of settings # that I define in local_django/conf/settings.py from django.conf import settings def foo(): return settings.some_setting Can I do some magic with the __import__ statement in myproject/__init__.py to accomplish this? Is there a more "pythonic" way to achieve this?

  • How do I pass a multi-dimensional array as a GET parameter in PHP?

    - by Onema
    I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for the url? if that is the case how? Thank you

  • Rails 3 full-text search options (gems, plugins, etc)

    - by shiftshane
    I was wondering if there were any suggestions for how to best roll with full text searching in your Rails 3 apps? Thinking Sphinx and acts_as_ferret aren't updated for Rails 3 yet, and even basic activerecord search helpers like Searchlogic also aren't there yet. Any thoughts? Are you using any forked versions of the above gems that have been updated to Rails 3?

  • How is the Viewflipper handling the back button in Android?

    - by Janusz
    I'm thinking about using a ViewFlipper for an Wizard like Activity. But I see one problem with this approach. The back button. Will the back button go back to the last shown activity or will the the Viewflipper somehow catch the back button event and only change to the last shown activity? I suspect the ViewFlipper to be treated as one Activity on the BackStack so is seems that is the wrong aproach for a wizard. Is this correct?

  • ASP.NET MVC Route based on Web Browser/Device (e.g. iPhone)

    - by Alex
    Is it possible, from within ASP.NET MVC, to route to different controllers or actions based on the accessing device/browser? I'm thinking of setting up alternative actions and views for some parts of my website in case it is accessed from the iPhone, to optimize display and functionality of it. I don't want to create a completely separate project for the iPhone though as the majority of the site is fine on any device. Any idea on how to do this?

  • encryption of a single character

    - by SystemicPlural
    What is the minimum number of bits needed to represent a single character of encrypted text. eg, if I wanted to encrypt the letter 'a', how many bits would I require. (assume there are many singly encrypted characters using the same key.) Am I right in thinking that it would be the size of the key. eg 256 bits?

  • How to get data source for Spring Security Web in Java code

    - by user1443689
    I'm creating a ZK Web application which uses Spring Security for authentication and I'm trying to implement a create user function, where the administrator supplies the details and the user account is created. I've got to the part where I want to put this data into the database, but now I'm thinking I shouldn't hard code the connection to the database, there must be a way to get the connection details from the Spring Security configuration. Is there? If so how?

    - by user146780
    I was wondering, since things like display lists are now deprecated, I'm thinking the GLU polygon tesselator is probably also deprecated. What is the new and correct way of creating concave or complex polygons and complying with the new GL 3 standard? Thanks.

    - by Sandeep Bansal
    Hi, I currently have a JSP page with a Form for the user to enter their name, but what I want is to get the user forwarded to a different JSP page after form submission and to carry on their name to be used. I don't want to use JSTL EL just simple JSP uses. I was thinking of using a bean storing the detail in a session but how would it work. Thanks.

  • Object responsibilities - list and item

    - by Mark Tyler
    My question is more like a theoretical. Say you have an object, that represents the list of something (articles, pages, accounts etc.) class ObjCollection You have a class, that represents a specific item in collection: class objItem I have a problem thinking of a basic responsibilities of each object. Which class is responsible for creating a new objItem? Which class is responsible for deleting a objItem? Should it delete itself as a method?

  • 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.

  • Does it make sense to have several UDP ports ready? Will packets be dropped?

    - by Gubatron
    I'm coding a networking application on Android. I'm thinking of having a single UDP port and Datagram socket that receives all the datagrams that are sent to it and then have different processing queues for these messages. I'm doubting if I should have a second or third UDP socket on standby. Some messages will be very short (100bytes or so), but others will have to transfer files. My concern is, will the Android kernel drop the small messages if it's too busy handling the bigger ones?

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

  • CPU ordering in Linux (with hyper threading)

    - by Jason
    I'm curious what the CPU ordering is in Linux. Say I bind a thread to cpu0 and another to cpu1 on a hyperthreaded system, are they both going to be on the same physical core. Given a Core i7 920 with 4 cores and hyperthreading, the output of /proc/cpuinfo has me thinking that cpu0 and cpu1 are different physical cores, and cpu0 and cpu4 are on the same physical core. Thanks.
