  • Graphical disk surface check tool?

    - by sbergeron
    I need a program that can scan my hard drive for read and write errors so I can partition around them. I REALLY don't do well with numbers but if I can have something that shows an output like the graphical display on gparted that would be perfect. I know a lot of people would recommend replacing the disk but right now I can't as I NEED this laptop for school and can't wait for a hard drive to arrive (I have ordered one, yes, but I don't expect it to arrive for another couple weeks as I only figured out afterwards they still have to manufacture it)

  • Interview Questions [closed]

    - by Pemdas
    Possible Duplicate: What techniques do you use when interviewing developers? Nearly every SE interviewing process has some sort of coding exercise to prove that the interviewee can actually write code. More often then not, the exercise also hopes to demonstrate that the interviewee can solve problems. However, this is often not sufficient enough to determine if the interviewee can actually design software. What are some effective ways to determine if an interviewee understands the basic concepts of design such as abstraction, interface design, thread management, ...ect?

  • Is perfectionism a newbie's friend or enemy? [closed]

    - by Akromyk
    Possible Duplicate: Where do you draw the line for your perfectionism? I see that the development community is very focused on doing things the right way and personally I would like to do the same too, however, is it a good or bad idea for a newbie to focus on design principles, design patterns, and commenting code when getting started, or is it better to let creativity run wild and potentially write sloppy code. Where should a newbie draw the line?

  • Programmatically Getting Name of Front-most (currently running) application in Unity

    - by NHDaly
    I am trying to write a script that executes differently depending on the currently active program, and I am wondering if there is any way to find this programatically. For example, I come from the Mac world, and in Apple's Applescript you can do the following: set appPath to the path to the frontmost application set appName to the name of file appPath and that will give you the name of the currently running application. Is there anything similar that I can do in ubuntu-land? Thanks!

  • How to get the blocks seen by the player?

    - by m4tx
    I'm writing a Minecraft-like game using Ogre engine and I have a problem. I must optimize my game, because when I try draw 10000 blocks, I have 2 FPS... So, I got the idea that blocks display of the plane and to hide the invisible blocks. But I have a problem - how do I know which blocks at a time are visible to the player? And - if you know of other optimization methods for such a game, write what and how to use them in Ogre.

  • why client can not receive message from server (java) [migrated]

    - by user1745931
    I have just started learning java. I modified the client side code for a server/client communication program, by creating two threads for the client side, main thread for receiving user's input, and inputThread for receiving server's response. I am sure that server has sent the response to client, however, no response message is obtain at client. Here is my code. Can anyone help me to figure it out? Thanks package clientnio; import java.net.*; import java.nio.*; import java.io.*; import java.nio.channels.*; import java.util.Scanner; public class ClientNIO { public static int bufferLen = 50; public static SocketChannel client; public static ByteBuffer writeBuffer; public static ByteBuffer readBuffer; public static void main(String[] args) { writeBuffer = ByteBuffer.allocate(bufferLen); readBuffer = ByteBuffer.allocate(bufferLen); try { SocketAddress address = new InetSocketAddress("localhost",5505); System.out.println("Local address: "+ address); client=SocketChannel.open(address); client.configureBlocking(false); //readBuffer.flip(); new inputThread(readBuffer); /* String a="asdasdasdasddffasfas"; writeBuffer.put(a.getBytes()); writeBuffer.clear(); int d=client.write(writeBuffer); writeBuffer.flip(); */ while (true) { InputStream inStream = System.in; Scanner scan = new Scanner(inStream); if (scan.hasNext()==true) { String inputLine = scan.nextLine(); writeBuffer.put(inputLine.getBytes()); //writeBuffer.clear(); System.out.println(writeBuffer.remaining()); client.write(writeBuffer); System.out.println("Sending data: "+new String(writeBuffer.array())); writeBuffer.flip(); Thread.sleep(300); } } } catch(Exception e) { System.out.println(e); } } } class inputThread extends Thread { private ByteBuffer readBuffer; public inputThread(ByteBuffer readBuffer1) { System.out.println("Receiving thread starts."); this.readBuffer = readBuffer1; start(); } @Override public void run() { try { while (true) { readBuffer.flip(); int i=ClientNIO.client.read(readBuffer); if(i>0) { byte[] b=readBuffer.array(); System.out.println("Receiving data: "+new String(b)); //client.close(); //System.out.println("Connection closed."); //break; } Thread.sleep(100); } } catch (Exception e) { System.out.println(e); } } }

  • What is the difference between "data hiding" and "encapsulation"?

    - by Software Engeneering Learner
    I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you create thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

  • First steps on setting up a query based server [closed]

    - by asghar ashgari
    I got a physical server at home and I want to do the following silly project to learn the concept behind server-backend development, and then do a real project later on: Idea: Turn the server to a calculator. I want any person publicly send a query to the server (i.e., 2+2) from the terminal and the server give me the result. So the question is basically where to start, what sort of software I need to install, and what sort of program I need to write?.

  • Functional vs. Non-Functional Requirements vs Design ideas in an SRS

    - by Nicholas Chow
    For a school project, I had to create a SRS for a "fictional" application. However they did not show us what it exactly entails, and were very vague with explanations. The SRS asked of us has to have at least 5 functional requirements, 5 non functional requirements and 1 constraint. Now I have tried my best to make one however I there are still some uncertainties left, I hope you experts can tell me whether or not I am thinking in the right direction. I will keep on updating this posts as I have questions regarding requirements that are vague to me, thank you all in advance for making SRS more clear for me FR1 Registration of Organizer FR1 describes the registration of an Organizer on CrowdFundum FR1.1 The system shall display a registration form on the website. FR1.2 The system shall require a Name, Username, Document number passport/ID card, Address, Zip code, City, Email address, Telephone number, Bank account, Captcha code on the registration form when a user registers. FR1.3 The system shall check whether the Name, Username, Document number passport/ID card, Address, Zip code, City, Email address, Telephone number, Bank account, Captcha code are filled out correctly within 1 seconds after a user submits the registration form. FR1.4 The system shall display an error message containing: “Registration could not be completed” to the subscriber within 1 seconds after the system check of the registration form was unsuccessful. FR1.5 The system shall send a verification email containing a verification link to the subscriber within 30 seconds after the system check of the registration form was successful. FR1.6 The system shall add the newly registered Organizer to the user base within 5 seconds after the verification link was accessed. Questions: FR1.1 Is this a functional requirement, or have I incorporated design idea in it by using "shall display on website". If so what would be a better way to write it? FR1.2 Is this better written in one requirement, or should I write each condition as a seperate requirement? FR1.3-1.5 Are these functional requirements or did I mix some non functional elements in it? How is it better phrased? FR1.3-1.6 Are these all correct functional requirements? As in free of ambiguity, complete, implementation free etc.

  • Interviewing Process (using blank paper etc)

    - by MJH
    I am curious to know why do companies hand you a blank paper and ask you to write code? This confuses me, because these days intellisense, google, stackoverflow etc are common sources to look up syntax and / or IDE gives you a colored indicator if your syntax is wrong. I usually get stressed out during these situations. I am curious to know opinions of other developers. I am posting this on this forum, hoping to get helpful feedback from other experienced developers.

  • Why do we need to put N before strings in Microsoft SQL Server?

    - by user61752
    I'm learning T-SQL. From the examples I've seen, to insert text in a varchar() cell, I can write just the string to insert, but for nvarchar() cells, every example prefix the strings with the letter N. I tried the following query on a table which has nvarchar() rows, and it works fine, so the prefix N is not required: insert into [TableName] values ('Hello', 'World') Why the strings are prefixed with N in every example I've seen? What are the pros or cons of using this prefix?

  • Where should Acceptance tests be written against?

    - by Jonn
    I'm starting to get into writing automated Acceptance tests and I'm quite confused where to write these tests against, specifically what layer in the app. Most examples I've seen are Acceptance tests written against the Domain but how about tests like: Given Incorrect Data When the user submits the form Then Play an Error Beep These seem to be fit for the UI and not for the Domain, or probably even the Service layer.

  • Should I have a separate method for Update(), Insert(), etc., or have a generic Query() that would be able to handle all of these?

    - by Prayos
    I'm currently trying to write a class library for a connection to a database. Looking over it, there are several different types of queries: Select From, Update, Insert, etc. My question is, what is the best practice for writing these queries in a C# application? Should I have a separate method for each of them(i.e. Update(), Insert()), or have a generic Query() that would be able to handle all of these? Thanks for any and all help!

    I've found this tutorial to install APC on servers with lighttpd + php 5.2 on Ubuntu 10. However, when I run sudo pecl install apc the package is just downloaded and is not installed. (i.e. I'm not asked the next question" and apc.ini file is not created at all. If I run only pecl install apc I get a warning (no permissions to write some files). (I need instructions for both 9.04 and 10.04) thanks
