  • When is a glue or management class doing too much?

    - by jprete
    I'm prone to building centralized classes that manage the other classes in my designs. It doesn't store everything itself, but most data requests would go to the "manager" first. While looking at an answer to this question I noticed the term "God Object". Wikipedia lists it as an antipattern, understandably. Where is the line between a legitimate glue class, or module, that passes data and messages from place to place, and a class that is doing too much?

  • Grid Game Algorithm

    - by 7Aces
    Problem Link - http://www.iarcs.org.in/inoi/2009/zco2009/zco2009-1a.php You have to find the path with the maximum weight, from the top-left cell to the bottom-right cell. It could've been solved with a simple Dynamic Programming approach, if it were not for the special condition - you are allowed at most one move that can be either to the left or up. How do I now approach the problem with this special case? Also, I'm looking for a time-efficient approach. Thanks!

  • What is your opinion of Ext js?

    - by marko
    I'm thinking of pushing my javascript skills further and learn something new. Is Ext JS a good framework to program to work in or is it a pain in the ass? I would consider ext js for making awesome looking business applications, and the framework is huge, but to use a big library I have some fears that it's difficult, buggy and time-consuming. My fear is that I wouldn't want to use some bloatware.

  • Sempron 145 core unlocking

    - by Grant
    Call me a cheapskate looking for performance, but I have a Sempron 145 processor that has been unlocked to an Athlon II X2 4450e with a GIGABYTE GA-990FXA-UD3 motherboard, but only one of the two processor cores can be used at a time. If both of the cores are enabled in the BIOS the kernel will hang during boot, If I reboot the system and disable the second core (but not re-lock the processor), it will take me to the grub and then start normally. Is there a way to enable both cores and boot without kernel hangs?

  • Is using dirname(__FILE__) a good practice?

    - by webose
    Looking at the code of Joomla I see that in the first line of the index, it defines the base path of installation with dirname(__FILE__). Is this a possible risk for the site? If a non controlled error message show the internal path of the Joomla directory, because of, for example a failed include, can it be used to perform some kind of attack to the site? If yes, is it convenient to use this function?

  • Are all View Models supposed to be accessed through the Main View Model in MVVM?

    - by chustar
    I am currently working on a WP8 application. My current design is to have each view bind against a specific view model directly. Looking through the samples though, it seems that another way is to have all the view models accessed through the Main View Model and then have all the views to their view models through the MVM. Is this the correct way to do it (So that it doesn't cause flexibility and other issues in the future)?

  • Java Grade Calculator program for class kepp geting the error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." [migrated]

    - by user2880621
    this is my first question I've posted. I've used this site to look at other questions to help with similar problems I've had. After some cursory looking I couldn't find quite the answer I was looking for so I decided to finally succumb and create an account. I am fairly new to java, only a few weeks into my first class. Anyway, my project is to create a program which takes any amount of students and their grades, and then assign them a letter grade. The catch is, however, that it is on a sort of curve and the other grades' letter are dependent on the the highest. Anything equal to or 10 points below the best grade is an a, anything 11-20 points below is a b, and so on. I am to use an array, but I get this error when ran "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." I will go ahead and post my code down below. Thanks for any advice you may be able to give. package grade.calculator; import java.util.Scanner; /** * * @author nichol57 */ public class GradeCalculator { /** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter the number of students"); int number = input.nextInt(); double[]grades = new double [number]; for (int J = number; J >=0; J--) { System.out.println("Enter the students' grades"); grades[J] = input.nextDouble(); } double best = grades[0]; for (int J = 1; J < number; J++) { if (grades[J] >= best){ best = grades[J]; } } for (int J = 0;J < number; J++){ if (grades[J] >= best - 10){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "A"); } else if (grades[J] >= best - 20){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "B"); } else if (grades[J] >= best - 30) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "C"); } else if (grades[J] >= best - 40) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "D"); } else { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "F"); } } // end for loop for output }// end main method }

  • A list of the most important areas to examine when moving a project from x86 to x64?

    - by AbrahamVanHelpsing
    I know to check for/use asserts and carefully examine any assembly components, but I didn't know if anyone out there has a fairly comprehensive or industry standard check-list of specific things at which to look? I am looking more at C and C++. note: There are some really helpful answers, I'm just leaving the question open for a couple days in case some folks only check questions that don't have accepted answers.

  • High-Powered Sites for low Cost

    - by HighAltitudeCoder
    Ahh, I am experiencing the intimidation of my very first post - visible by the whole world. Ok, here goes.   This first post is nothing exceptional.  It is simply a recommendation based (fittingly, I suppose) upon the job search you may be gearing up for.  I find myself in this very situation right now.  And, I will take my own recommendation after posting this entry. Job-Seekers: To the left you will notice two links under "Recommended Learning".  I have found these links to be invaluable when it comes to re-tooling, re-familiarizing, or otherwise resharping my skills when looking for that next job. Often, you will find job-postings with the text, usually posted after a laborious list of qualifications indicating the company's desire to hire candidates who know what they are doing: "...Looking for a candidate who can hit the ground running...".  The interesting thing about this post to me is I've encountered many individuals who, after speaking and working with them for some time, I've realized are perfectly capable of hitting the ground running - and FAST.  But what if they speed off in the wrong direction? The next time you spearhead a major task in your job, ask yourself: Am I headed in the wrong direction?  There are many ways to do this.  In fact, I've found in this new field there are more tempting ways to steer your project in the wrong direction than there are good ones.  I don't want to suggest that every one of my posts will fall into the "right direction" category, however I do think a healthy dose of introspection of the pros and cons will always be beneficial before you set off. That said, allow me to expound on the previously mentioned links. These web sites are invaluable.  They demonstrate the capabilities of existing as well as new and upcoming tools available in several IDE's.  I've viewed many tutorials in LearnVisualStudio.NET, and only one or two so far in TrainingSpot, however I've been delighted in their simplicity and straightforward approach to proper usage of the particular tool or concept being discussed.  They have not (so far in my experience) demonstrated ways in which to use the tools that become cumbersome, impractical, or error-prone. Each website has step-by-step videos that can be paused, replayed, and most importantly, they are done in real time.  As the author is typing, the viewer gets to experience the coding experience from a first-person perspective, including syntax errors, unexpected behaviors, IDE setup idiosyncracies, everything.  A subtle value I've gained from these videos is that a certain degree of confusion and introspection is normal when working with new tools and exploring new paths.  They (as well as your own experience) are not to be feared, but enjoyed.  I highly recommend them. Good work, guys!

    Alright, so I have a user table and would like to get the max value for the user with the highest amount of points divided by a score. Below is a rough idea of what I'm looking for: SELECT MAX(SUM(points)/SUM(score)) FROM users I'm not interested in adding up both columns and dividing, rather I'm interested in dividing the points and score for each user and retrieve the highest value out of the lot.

  • How does ReSharper V7 compares against V5? [closed]

    - by Alex. S.
    I was told by my boss we need to buy some more licenses of ReSharper and getting the quote of that we also received the quote of an upgrade to the newest version (v7) for everyone here. We are a small shop of 20 C# developers working with VS2010 We previously were working with an older version (v5) so I wondered what are the key differences between both versions, from a practical point of view, because the upgrade fee is greater than zero. I reviewed the website and of course it seems interesting, and I'm looking for arguments if it's a worthwhile investment upgrade.
