  • How can you get the first digit in an int (C#)?

    - by Dinah
    In C#, what's the best way to get the 1st digit in an int? The method I came up with is to turn the int into a string, find the 1st char of the string, then turn it back to an int. int start = Convert.ToInt32(curr.ToString().Substring(0, 1)); While this does the job, it feels like there is probably a good, simple, math-based solution to such a problem. String manipulation feels clunky. Edit: irrespective of speed differences, mystring[0] instead of Substring() is still just string manipulation

  • Skip maven2 plugin by default

    - by Octoberdan
    Hello, I am looking for a way to not have a plugin execute on install. More specifically, my scenario is as follows: I am using org.apache.cxf:cxf-codegen-plugin to generate source code. Every time I clean+install the source is generated I only want generation of source code to happen when I explicitly request it. Any and all help would be greatly appreciated!

  • updating a shape in scene with a for loop using javafx

    - by Susanta
    Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

  • Client for restful web service

    - by Ish
    I'd like to create a http-centric client for a restful web service created using CXF. To that end: Does any one know the (maven) dependencies for ONLY the CXF clients (Proxy & HTTP)? Is there any advantage to using CXF's built-in clients over say, Apache HttpClient?

  • What's the silliest programming mistake you've ever done? [closed]

    - by bgo
    Despite not being a professional programmer, i use python or c to accomplish simple tasks. Once I needed a nasty equation to use with various data for physics lab. I thought that it would take a few hours if i used some mechanic calculator. Then i've written a python script to make things easier but something was wrong. After finding my mistakes one of which was forgetting to put ":", i realized that it had already took 2-3 hours, not to mention inventing satanic arithmetic techniques since i thought the errors was caused by my math :) Sometimes when you don't see it, you don't see it! Now i can find the syntax errors without thinking for a moment :) Any similar annoying mistakes that you've experienced?

  • Recursive Functions for Beginners?

    - by cam
    I'm looking for a few recursive function examples, preferably ones that show increase in complexity. I understand basic recursive functions, but I'm having trouble implementing them in my code. I've never used them in my code before, and I know it doesn't always call for it, but I'd like to try. Is there a good resource with examples, and maybe challenges of some sort? Or even some simple math problems (Project Euler-style?) that I could use recursion on? For examples, I prefer C#, but anything works.

  • user specifc maven settings in repository

    - by Samuel
    http://maven.apache.org/settings.html As per documentation the user specific settings can be either copied to the .m2 folder or under the maven installation. If a developer changes a machine or gets a new user id, such properties have to be copied manually to these newer machines. Would it be possible to store user specific setting information in the repository itself (say SVN) and somehow have the mvn scripts load it on startup.

  • Intermittent/staggered loading of an object

    - by cammy
    Hi guys, I've just recently tried my hand at actionscript 3 and have come across a road block. How do I go about rendering the cubes (cube1) intermittently, ie. staggered loading. I need the cubes to load a split second from each other. Below is a snippet of what I have so far: var rows:int = 5; var cols:int = 3; var spacery:int = 100; var spacerx:int = 120; var box_count:int = 8; for(var i:int; i < box_count; i++) { cube1 = new Cube(ml,100,10,80,1,1,1); cube1.y = ((i % rows)) * (cube1.x + spacery); cube1.x = Math.floor(i/rows) * (cube1.x +spacerx); cube1.z = 0; bigBox.addChild(cube1); }

  • github repos cloning, but no tags/branches recreated??!!

    - by deepblue
    I've been cloning a few repos from github that, even though I know they have branches/tags, do not have them once I clone them onto my local drive. strage. I try to list the tags (git tag) but nothing comes up... I would look into .git/refs/tags/ and that too is empty. the repos in question are: http://github.com/jchris/hovercraft.git http://github.com/apache/couchdb.git any ideas? I really need specific tags/branches, and not the HEAD of the master

  • Given a number N, find the number of ways to write it as a sum of two or more consecutive integers

    - by hilal
    Here is the problem (Given a number N, find the number of ways to write it as a sum of two or more consecutive integers) and example 15 = 7+8, 1+2+3+4+5, 4+5+6 I solved with math like that : a + (a + 1) + (a + 2) + (a + 3) + ... + (a + k) = N (k + 1)*a + (1 + 2 + 3 + ... + k) = N (k + 1)a + k(k+1)/2 = N (k + 1)*(2*a + k)/2 = N Then check that if N divisible by (k+1) and (2*a+k) then I can find answer in O(N) time Here is my question how can you solve this by dynamic-programming ? and what is the complexity (O) ? P.S : excuse me, if it is a duplicate question. I searched but I can find

  • Is my code really not unit-testable?

    - by John
    A lot of code in a current project is directly related to displaying things using a 3rd-party 3D rendering engine. As such, it's easy to say "this is a special case, you can't unit test it". But I wonder if this is a valid excuse... it's easy to think "I am special" but rarely actually the case. Are there types of code which are genuinely not suited for unit-testing? By suitable, I mean "without it taking longer to figure out how to write the test than is worth the effort"... dealing with a ton of 3D math/rendering it could take a lot of work to prove the output of a function is correct compared with just looking at the rendered graphics.

  • What is the fastest / best Base64 en/decoder for Java ?

    - by mP
    Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the non fast methods which make assumptions trading possible correctness for pure speed.

(button created via IB) Thanks! mE ps: I have looked at similar posts and my code looks fine but I keep getting zeros (it's an ipad app if matters in any way)
