  • Designing exceptions for conversion failures

    - by Mr.C64
    Suppose there are some methods to convert from "X" to "Y" and vice versa; the conversion may fail in some cases, and exceptions are used to signal conversion errors in those cases. Which would be the best option for defining exception classes in this context? A single XYConversionException class, with an attribute (e.g. an enum) specifying the direction of the conversion (e.g. ConversionFromXToY, ConversionFromYToX). A XYConversionException class, with two derived classes ConversionFromXToYException and ConversionFromYToXException. ConversionFromXToYException and ConversionFromYToXException classes without a common base class.

  • How many tiers should my models have in a DB driven web app?

    - by Hanno Fietz
    In my experience, the "Model" in MVC is often not really a single layer. I would regularly have "backend" models and "frontend" models, where the backend ones would have properties that I want to hide from the UI code, and the frontend ones have derived or composite properties which are more meaningful in the context of the UI. Recently, I have started to introduce a third layer in between when database normalization created tables that did not really match the conceptual domain objects anymore. In those projects I have model classes that are equivalent with the DB structure, these become components of objects that represent the domain model, and finally these are filtered and amended for displaying information to the user. Are there patterns or guidelines for how, when and why to organize the data model across application layers?

  • Live-Ubuntu 12.04 ran fine, now stopped booting!

    - by user89743
    I've seen similar problems to this several times in the forum, but mine is a bit different, so the other posts I saw were no help to me. When I boot Ubuntu 12.04 64-bit from live-SD-card (3GB persistence) I suddenly get this error: (initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Invalid argument Can not mount /dev/loop/0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs (it says I can type "help" for commands, but I don't know anything about how to go from there, totally new to linux) The reason I say my case is different is because my Ubuntu worked fine for over a week, even pretty fast, and now this problem happened. Before that I used to run my live ubuntu from USB sticks but that was slower (especially when booting which took 15 minutes from USB stick!). Also I kept getting the same above problem after a while when booting and had to re-create a live USB linux several times. Installing on harddrive is not an option because my harddrive has physical damage and getting a replacement will take a while, therefore I can only use live-USB or live-SD-card Ubuntu. As I said I used Ubuntu without problems for more than a week, before that as well for several weeks on USB sticks, but the above problem occured sooner or later. This time I paid attention to when it happened: I was rebooting my computer (HP 620 laptop, 4 GB RAM, 64 bit system) from SD flash card and when I was booting I selected F6 and then the first option "no acpi" or something like that...I had used it before and noticed it slowed down the time it took Linux to use. This time it caused this error. Now even when I boot normally/default I get this error. Now I'm accessing Ubuntu from my USB stick without persistence file, when I check my SD card, all the files mentioned in the error message are there and the filesystem.squashfs is 691.2 MB so nothing seems to have been deleted by accident. (I have already made many changes/downloaded programs to my SD card persistent Ubuntu and would hope to loose them, since downloading is expensive for me, and since the problem seems to re-occur...) Can anyone help me, preferably without having to create another startup disk on my SD card? I'm totally new to this. Sorry for the long posts, just didn't know what info is relevant and what isnt!

  • Truly useful UML diagrams

    - by eversor
    UML has a jungle of Diagrams. Profile Diagrams, Class Diagrams, Package Diagrams... However, (IMH-and-not-too-experienced-O) I quite see that doing each and every diagram is overkill. Therefore, which UML Diagrams are more suitable in a web context, more expecificly a blog (we want to build it from scratchs). I understand that just because I used UML Diagrams does not imply that our code would be great and brilliant... but, it certainly would be better than just unplanified code...

  • php application deployment to redhat [closed]

    - by Subhash Dike
    I am a .net background person with most of the work with Windows environment and IIS etc. I have been given a task to deploy one php application on RedHat Linux box. All I have is the credentials and the server IP of that box. Can someone help about how to get started creating a new website on Apache 2.0 on redhat box and then putting php code over to that. I do not have physical access to that server as well. I know it's very basis question, but I am in dark for these things. Even if you can point me to some documentation that's fine or else at least the analogy with IIS should also help to certain extent.

  • Not Quite Multiseat

    - by user2773520
    I am attempting to create a pair programming environment sort of set up like multiseat: https://help.ubuntu.com/community/MultiseatX[1] or https://help.ubuntu.com/community/MultiseatOneCard[2] (as the standard issue boxes only have one graphics card) The thing is, I only want one login session, just with 2 monitors, keyboards, and mice. As well as having 2 active applications (so 2 people can be typing independantly). They should ideally be able to mouse over and click & type in the other persons monitor, as well as move windows between the montors. Does anybody know of anything like this that will work? We are running Ubuntu 12.04.

  • Cannot connect to Internet on 11.04 using BSNL EVDO Prithvi Card

    - by Joy
    I cannot connect to Internet using BSNL EVDO Prithvi data card. Went through some websites that offered help, installed wvdial package and tried again, but was unsuccessful. I have Read that, Ubuntu 11.04 automatically detects Data Card, You only need to configure "Network Manager" and it will work, I did exactly that, but the result is same. The OS detects the data card, and the presence of network , but it cannot login. I have read in some forums that Ubuntu 11.04 does not have support for BSNL EVDO Prithvi, is it true? I re-checked the "User ID" and "Password". Its working on Windows. Please help me fix this.

  • [EF + Oracle] Intro

    - by JTorrecilla
    Prologue I have a busy personal and working time, and at this moment that I start to get more free time, I decided to start a Serie about Entity Framework with Oracle. A few time ago, I got my first experience with EF and Oracle with Oracle 10 g express and Oracle 10 g with the same results, Doesn’t work. Now I download Oracle 11 g to Test again. Tools To start using EF with Oracle we need the following: 1. Visual Studio 2010. No Express Edition 2. Oracle 11g 3 Oracle Driver for EF (ODAC) Intro People, who are starting with EF developments, I recommend to take a look into Unai Zorrilla’s Blog, the post were written in Spanish but they are great! To this Serie, we are going to define the DB from the Oracle administrator. For that we need to follow the next steps: 1. Create a User with a PassWord. In my example the user will be Jtorrecilla 2. Create a TableSpace 3. Define some example tables   (Image1) When we have created the DB, we are going to start a new project in VS 2010. I will start a C# Project. To start with EF, we need to add a new objet to our Project “ADO .NET Entity Data Model". (Image2) The next step will be to indicate that our model will be based on an existing DB, and indicate the connection string (Images 3 and 4): (Imagen3) (Imagen4) Once we selected the connection string, we will need to indicate that in the connection will be saved “Sensitive” data (Image 5), and in the next step we are going to select the DB objets to use in the project(Image 6).   (Image 5) (Image 6) A the end of the selection, we will press Finish button, and it will generate a EDMX file to add to our solution, and in the IDE will appear the DB Schema with the selected Tables and Relations. (Imagen7) One Entity is composed by a set of properties (each matches with a column from the Table in the DB) and Navigation Properties that represents any relation with other Entities.   Finally With this chapter we have installed the environment, defined a DB and configured the solution to start using EF with Oracle. In the next chapter we are going to see What is a Entity and how it works. I hope you enjoy this Serie!

  • Broken Links in different browsers

    - by kdorival
    Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???

  • pointer jumping about Lubuntu 12.04

    - by Gary Kirkpatrick
    Using 12.04 on a Samsung NC110. If I disable Touchpad, the cursor does not jump about while typing. This is very very annoying. Tried this tutorial, but this does not help. The problem occurs even when my fingers are well away from the Touchpad. I wonder if another key or key combination causes this problem? I sure could use some help on this. I have had this problem with various versions of Ubuntu and now Lubuntu.

  • Kernel Panic Fatal Machine Check

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(

  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • Which are the most frequent exceptions thrown in Java applications? [on hold]

    - by Chris
    1. Do you know of any statistics about the frequency of exceptions (checked and unchecked) thrown at runtime in typical Java applications? for example: NullPointerException: 25% of all exceptions ClassCastException: 15% of all exceptions etc. 2. Which are the most frequent exceptions according to your own experiences? 3. Would you agree that the NullPointerException is generally the most often thrown exception? I am asking this question in the context of the compiler development of the PPL programming language (www.practical-programming.org). The goal is to auto-detect a maximum of frequent exceptions at compile-time. For example, detecting all potential NullPointerExceptions at compile-time leads to null-safe software which is more reliable.

  • SEO Mapping, Tracking and Reporting

    Linking the pages of a website is done because search engines will be more aware of a site's presence when its pages are found at the other end of industry terms in anchor text contained with content at other locations. The total and quality of those links are factors that help promote rankings; when placed for SEO purposes they should be one-way links rather than reciprocal since reciprocal links are not any help in ranking brownie points and it is prohibitively time-consuming to administer a thousand of them. This is not to be confused with link exchanges; when you can...

  • Right-click acts too fast - No Fix Yet, Any Workaround?

    - by Aahan Krish
    When I click the right mouse button (anywhere, be it - desktop, browser, console, etc.), the right-click context menu pops up so quickly that the very *first* option in the menu gets clicked. This happens too often to take it easy. This issue has been brought up a couple of times on Ask Ubuntu, but with no fix whatsoever. This is a very low priority issue for the Ubuntu team, I believe? (How could they?!) Is there at least a workaround for the issue? Ubuntu is almost unusable for me as it is now. PS: I have a new mouse. So, please don't go about suggesting that I get a new one - - everything's working fine on Windows 7, so should be the case with ubuntu 11.10, which it is not.

  • How can menu bars that require a right click be activated like Ubuntu versions <10.10?

    - by Amos Annoy
    I've noticed that NetworkManager only has a single, left or right, click menu and no longer has an About menu option to show it's splash screen. In fact all the top bar mini short cut icons have been amputated and crippled leaving them with no rights. This severely impacts on our custom aps., similar to FireFox bookmarks, which can no longer be right clicked to bring up a context menu. It is possible to disengage FF's File|Edit|... menu bar from the top by running it in safe-mode so the menu bar is resident in a window, restoring right clicks, but our aps. do not have "safe modes". How can right clicks in menu bars be restored? reference

The reason why I am asking for help now is that I don't have a clue why my newly added accordion(s) do not expand upon being clicked. I've got a feeling it may be due to the newly added code as I was having problems using my code in the file so instead I looked at the source and copied the accordion level to be used and all appears to look fine apart from them not expanding. Thank you for any help in advanced, Best Regards, Tim
