• Most appropriate diagram for GUI button design?

  - by JustADude

  What is the most appropriate diagram for GUI button design? Specifically, I have numerous buttons that will be changing color based on state information from operator input and input from various subcomponents and sensors. I would like to use UML or some other type of design diagrams to be able to capture the color transition. Some folks have suggested sequence diagrams, but I haven't been able to find any good examples that show how to incorporate this design artifact. I would really like to head in this direction to help developers. Thanks a ton for feedback and insights.

• Why is Prolog associated with Natural Language Processing?

  - by kyphos

  I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

• How to fend off external interuptions?

  - by Demian Kasier

  I want to keep my focus at work, but I am constontly interupted. examples: - the boss asks something to the whole team. - a coleague asks something about a piece of code I wrote - something funny on the radio - smalltalk among coleages with a joke in between. - ... As extra info: We are a team of 6 developpers in one room, with sales and suits constantly coming over to ask and tell us things we must and mustn't do. So how do you keep you focus and attention to your work? so you can get some things done, instead of answering to everyone and everything that interupts you?

• DMCA in Europe - EUCD?

  - by rlcabral

  There is a site to where I need to send a takedown notice. However, this site is hosted in Europe with an offshore hosting company that says clear in its TOS that they will not do anything if they get a DMCA complain, giving freedom to clients to host whatever copyrighted material they want. Is EUCD the correct way to deal with this? Where can I find an example of a EUCD complain or even a form? DMCA has all types of examples and places to get a sample form, but EUCD has none.

  - by LostInLib

  I'm trying to develop a desktop application which is similar to CCleaner. But I'm having problems with R&D resources... I can't find good books about Windows Operating System Programming Topic Examples; Explaining Windows 7 (or even 8) registry. Which registry entry turn on/off "showing desktop icons" Or, What is Windows registry defrag?, How can you defrag registry?, How can you optimize windows startup for( Windows 7 ) etc. I googled my questions, find msdn-some stackoverflow topics etc. But I can't find a book about low-level explaining current windows 7 operating system... What I'm missing ? Thanks for your any input... and sorry, I don't know is this the right place to ask that question, but I asked anyway...

• What things to take into consideration when refactoring code?

  - by JustaPro

  Code refactoring is a "disciplined technique for restructuring an existing body of code, altering its internal structure without changing its external behavior" Could anyone explain this definition? I find it kind of blurry. Which is the best technique to do it? Are these the only ones? Which are the obstacles one would meet when refactoring code? What to take into consideration when switching between IDEs? Do tools which help refactoring exist? If yes, which one would you recommend using? Any references to links where I can find out more on this subject or to books that have been written are welcomed. The questions above are for any programming language, but specific examples are appreciated. Anything that would clarify this for me is.

• Separating merged array of arithmetic and geometric series [closed]

  - by user1814037

  Possible Duplicate: Separating merged array of arithmetic and geometric series My friend asked me an interseting question. Given an array of positive integers in increasing order. Seperate them in two series, an arithmetic sequence and geometric sequence. The given array is such that a solution do exist. The union of numbers of the two sequence must be the given array. Both series can have common elements i.e. series need not to be disjoint. The ratio of the geometric series can be fractional. Example: Given series : 2,4,6,8,10,12,25 AP: 2,4,6,8,10,12 GP: 4,10,25 I tried taking few examples but could not reach a general way. Even tried some graph implementation by introducing edges if they follow a particular sequence but could not reach solution.

• Which tasks should a beginner, intermediate and advanced rails developer be able to complete?

  - by raouldeveloper

  I have been programming ROR for about a year now, and I think I am ready to start working on a project for someone else. The problem is that job postings for contractors don't really tell you which specific tasks you should be able to do at different experience levels (in rails and other technologies), so I don't know where to pitch myself. I think I am somewhere between junior and mid-level, but who knows? So my question is: Which actual tasks should an junior programmer be able to do at, say, $35 an hour, which actual tasks should an intermediate programmer be able to do at, lets say, $75 an hour, and which actual tasks should an advanced programmer be able to do at, oh say, $140 an hour? One or two examples should suffice.

• GMail API for a small app (Rails? Javascript? PHP?)

  - by kurtybot

  I want to create an app that accesses the GMail API, but I'm finding that it isn't as simple as I thought it might be. I'm hoping somebody in the community here might have some experience working with one of these API's and could not only recommend the right solution, but also show me to some tutorials or examples that could help me get up and running. Here are some of the requirements of this app: Preferably in Rails or Javascript or even PHP. I am open to other technologies as well, but hope they'd be easy to implement. Connects to gmail via Oauth Can read who emails have been sent to and received from. Basically would like to perform some analytics on who emails are sent to, when and how frequently. I've read that one reason why this isn't easy, and why there isn't an official javascript API provided by gmail, is that google is concerned it's going to make their service less performant for their users.

• What's the difference between set, export and env and when should I use each?

  - by Oli

  Every so often I'll bash out a bash script and it strikes me there are a few ways of setting a variable: key=value env key=value export key=value When you're inside a script or a single command (for instance, I'll often chain a variable with a Wine launcher to set the right Wine prefix) these seem to be completely interchangeable but surely that can't be the case. What's the difference between these three methods and can you give me an example of when I would specifically want to use each one? Definitely related to What is the difference between `VAR=...` and `export VAR=...`? but I want to know how env fits into this too, and some examples showing the benefits of each would be nice too :)

• Point and click synonym replacement in text area with Javascript

  - by SilentD

  I am trying to create a site that will allow you to type a sentence or passage of text, then click on words to bring up a list of synonyms (from an online API) and possibly authorized abbreviations from a list that I provide, then once clicked on it would replace that word with the word that was clicked on. It would function kind of like After the Deadline or a Javascript based spell checker. Are there any libraries set up to make something like this easy, or what kind of Javascript do I need to be looking at? Are there any tutorials or examples for this kind of thing? I am aware that the source code for After the Deadline is available, but I only need a small portion of their technology, not all of the actual grammar and spelling check technology.

• Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?

  - by Andy Harglesis

  I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however. 2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up: 1.When the pixels touch; 2.when a rectangle range is exceeded; 3.when a pixel object is detected near another one in a pixel-based rendering engine. But 3-D is different with one dimension, but complex in many more so ... what are the general, basic understanding/examples on how 3-D collision detection can be implemented? Think two shaded, OpenGL cubes that are moved next to each other with a simple OpenGL rendering context and keyboard events.

• Ubuntu 12.04 appearance

  - by lightnight

  I have just updated my old Ubuntu 11.04 to the 12.04 version and I really dislike the new appearance. Is there anyway I can go back to the old appearance? Here are some examples of the things I would like to change: the omnipresent orange colour (for example, colour of the folders, colour of the little x on the top right of the window etc.); used to be blue. The icons on the right vertical bar are unreadable: the dropbox icon has become a light grey shapeless blob, the battery icon does not indicate, as it did before, when electricity is plugged in and when it isn't. everything is just grey and orange (I chose the Radiance theme, the other ones are even worse). There used to be a lot of options choosing the shape of the windows and so on, where has all that gone? Thanks for your help!

• Creating an OpenGL FPS camera: I have the position and orientation vectors, now what?

  - by Synthetix

  I have been struggling to create a first person camera in OpenGL ES 2.0 without using gluLookAt(). I grab the camera's orientation vectors (the way it's looking) from the current modelview matrix, and use that to calculate the new forward/backward (Z) translation value. I then calculate the strafe (X) value from the dot product of Z and Y (which is always 1.0). So, I have all the information I need to create a view matrix, but how do I do that without using gluLookAt? Almost all the examples I've seen use gluLookAt, but no such function exists in OpenGL ES 2.0. Besides, one of the moderators on cprogramming.com mentioned that gluLookAt is not appropriate for FPS cameras: http://cboard.cprogramming.com/game-programming/135390-how-properly-move-strafe-yaw-pitch-camera-opengl-glut-using-glulookat.html I am really confused by all the conflicting information I'm getting. I just want to create a first person camera that goes forward (W,S keys), side-to-side (A,D keys) and rotates around its center (Y axis only), Wolfenstein style. Any help on this would be much appreciated!

• Is it normal to feel bad when someone insults a programming language? [closed]

  - by iammilind

  Few examples before the question: "A language is just a tool; Better to worry only about the concept." "C++ is just an object oriented language." "Java is more about the libraries and less about programming." "C# is just a Microsoft's version of Java with some extra things from C++." "Python is a scripting language used mainly for testing purpose." ... All these statements are made knowingly or unknowingly from my colleagues/friends and I often get to hear them. I feel bad when someone brings down any programming language. I don't know how to respond. Is there any one liner to enlighten those people?

• What do Embedded Software Developers do on a day to day basis?

  - by afree100

  Edit: I am not asking how to program embedded systems. I am asking how it is done in a practical business setting. I have searched for hours for information on what software developers actually do. More specifically, what coding challenges would one experience daily (e.g. code examples (although obviously not too large), specifics)? I am interested in Linux based embedded systems mainly, but any software development would be helpful (in the C/C++/Assembly areas). Also, regarding this, a distinction between junior, intermediate and senior developers would be helpful. Also, what is the best place to prepare for such things before getting a job for the first time?

• Are nested classes under-rated?

  - by Aaron Anodide

  I'm not trying to say I know something everyone else doesn't but I've been solving more and more designs with the use of nested classes, so I'm curious to get a feeling for the acceptablilty of using this seemingly rarely used design mechanism. This leads me to the question: am I going down an inherintly bad path for reasons I'll discover when they come back to bite me, or are nested classes maybe something that are underrated? Here are two examples I just used them for: https://gist.github.com/3975581 - the first helped me keep tightly releated heirarchical things together, the second let me give access to protected members to workers...

• How can I convince a project manager that there is no way to solve all the compatibility issues?

  - by SAFAD

  I have been working on this project for more than a year now, and we are close to release, the project manager wants the product to be perfect and working in every single aspect. I like that and I love working under the perfection idea, but it seems he is delaying the launch too much because of compatibility issues, he wants the product to work in every single installation, every single configuration possible, and in most cases, the product just works without issues when it's on the hands of the client. UPDATE : yes the product doesn't work properly when there are conflicts, for example, other products that don't use guidelines nor standards to load libraries (causes double library load which leads to failure), cache is another example and so on..... but we warn the clients about the conflict before purchasing and help them fixing it after purchasing I've tried to explain it by giving some examples on major products, he understands the situation, but can not believe that it is near impossible (if it is not impossible) to do what he wants. Hope it is clarified enough for the community to answer.

• Should I pass an object into a constructor, or instantiate in class?

  - by Prisoner

  Consider these two examples: Passing an object to a constructor class ExampleA { private $config; public function __construct($config) { $this->config = $config; } } $config = new Config; $exampleA = new ExampleA($config); Instantiating a class class ExampleB { private $config; public function __construct() { $this->config = new Config; } } $exampleA = new ExampleA(); Which is the correct way to handle adding an object as a property? When should I use one over the other? Does unit testing affect what I should use?
