• Securing User Account Details with MySQL

  - by Antoinette O'Sullivan

  Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures. You can learn more about this and many other topics in the MySQL for Database Administrator course. For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security. The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text. The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a: Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule.

• Easy user management on html site?

  - by James Buldon

  I hope I'm not asking a question for which the answer is obvious...If I am, apologies. Within my html site (i.e. not Wordpress, Joomla, etc.) I want to be able to have a level of user management. That means that some pages I want to be only accessible to certain people with the correct username and password. What's the best way to do this? Are there any available scripts out there? I guess I'm looking for a free/open source version of something like this: http://www.webassist.com/php-scripts-and-solutions/user-registration/

• Lubuntu Desktop messed up for logged in user, but not for guest

  - by RPi Awesomeness

  I recently upgraded my laptop from Lubuntu 12.04 to 14.04.1 and the upgrade process seemed to go fine. However, when I went to login as my normal user, I encountered an issue. The background loaded up, but none of LXDE or LXPanel showed up, leaving me with an empty desktop and nothing else except two errors. I thought that this was weird, so I just figured something had been messed up and would be fixed by a reboot. But it wasn't. I then tried logging in as guest, and it's just fine. I checked the ~/.xsession-errors file (for my main user, not guest, did it via TTY1) and this is what I got: Script for ibus started at run_im. Script for auto started at run_im. Script for default started at run_im. init: Unable to register as subreaper: Invalid argument init: lxsession main process (1649) killed by TERM signal init: Disconnected from notified D-Bus bus init: job dbus failed to stop init: job upstart-dbus-session-bridge failed to stop init: job upstart-dbus-system-bridge failed to stop init: job upstart-file-bridge failed to stop I also read the sometimes removing the ~/.Xauthority file can help, if the ownership is messed up. ls -l /home/MYUSER/.Xauthority tells me -rw------- 1 MYUSER MYUSER 60 Aug 16 09:57 /home/MYUSER/.Xauthority. Should that be root or something else, or should I try deleting that and ~/.profile. Here's what ~/.profile looks like: # ~/.profile: executed by the command interpreter for login shells. # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # see /usr/share/doc/bash/examples/startup-files for examples. # the files are located in the bash-doc package. # the default umask is set in /etc/profile; for setting the umask # for ssh logins, install and configure the libpam-umask package. #umask 022 # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi Should I post the output of dmesg? I'll try and get a screenshot, but does anyone have any idea what could be causing the desktop (LXDE/LXPanel) not to display? EDIT I attempted removing the ~/.XAuthority file, but that didn't seem to do anything.

• When should a method of a class return the same instance after modifying itself?

  - by modiX

  I have a class that has three methods A(), B() and C(). Those methods modify the own instance. While the methods have to return an instance when the instance is a separate copy (just as Clone()), I got a free choice to return void or the same instance (return this;) when modifying the same instance in the method and not returning any other value. When deciding for returning the same modified instance, I can do neat method chains like obj.A().B().C();. Would this be the only reason for doing so? Is it even okay to modify the own instance and return it, too? Or should it only return a copy and leave the original object as before? Because when returning the same modified instance the user would maybe admit the returned value is a copy, otherwise it would not be returned? If it's okay, what's the best way to clarify such things on the method?

• Detail of acceptance criteria in user story

  - by Kai Kramhoeft

  I have the following example for a user story with acceptance criteria. I would like to know if I am allowed to describe how the GUI must be changed to support the new feature. How much detail can acceptance criteria have? This is my example: User Story: As forum administrator I will connect persons in groups, so that people can get organized. Acceptance Criteria: The creation of a person group happens below a person group pool (person group pool is an object also visually available in the current software system) The creation happens with a context menu of the persongroup pool. Below the pool one can create new groups. A person group contains: person group-ID, description, remark May that be relevant an right acceptance criteria? Because I describe how you can create a new group by opening a context menu.

• Report Builder 2.0 - Creating DataSet - User Not Authorized

  - by Fahad

  Hello, we are currently using SQL Server Reporting Services and we would like to use Report Builder so our customers can create reports themselves. I have created a User on the server. I have added this user to the SQLServerMSSQLUser and SQLServerReportServerUser groups. I have given this User db_datareader access to the required database and to the Reporting Services database. I've also tried giving the User db_owner access to the Reporting Services db's. And on the Report Manager, this User is a System_User, but has all access (every checkbox is checked). When I connect using Report Builder, I can select the Report Model to create a DataSource, but when I try to create a DataSet, I get the following error: An error occurred while connection to datasource 'DataSource1'. The details are: 'User Not Authorized'. Does anyone know what server permissions I forgot to set? I'm assuming it's a Windows permissions issue because I do not see any database login errors in the event logs.

• how do you read from system.out in Java [closed]

  - by Dan

  I'm trying to create a word scramble game and so far I have taken a vector of randomly assorted strings that contains both words and hints and split them into two vectors. I have randomly scrambled the word and set this all up in text boxes. Right now I'm stuck because I have a text box that takes input but I'm not sure how to read that in? I want the user to type the unscrambled word into the text box and have it calculate as correct and move on to the next word immediately. I also don't know how to get the keys working. I want the "?" character to be the hint button that shows the hint. At the moment the hint box works if I type the question mark in using the System.in but it doesn't work if I type it directly in to the text box. The characters are showing up in the text box but nothing is working after that.

• cocos2d-x - object creation and management in game design

  - by Jason

  How do others keep track of everything going on in their games? I am working on a new game and I am quickly realizing everything that I need to keep track of. Example: Maybe a layerManager that keeps track of all the layers and what is happening for a particular scene. Maybe a sceneManager for sharing objects among scenes But then getting to game play itself, what if you have 100 objects on the screen each with its own state and happenings, there needs tobe a way to keep track of all of that. Drawing everything out is really helping me. Can anyone share with me how they go about object tracking/management? I am seeing a few different managers and then maybe even a parent object that manages the managers..is my thinking way off? Any design patterns that may be useful for me to read about? Update: doing some reading and maybe a Factory pattern might apply.

• chrooting user causes "connection closed" message when using sftp

  - by George Reith

  First off I am a linux newbie so please don't assume much knowledge. I am using CentOS 5.8 (final) and using OpenSSH version 5.8p1. I have made a user playwithbits and I am attempting to chroot them to the directory home/nginx/domains/playwithbits/public I am using the following match statement in my sshd_config file: Match group web-root-locked ChrootDirectory /home/nginx/domains/%u/public X11Forwarding no AllowTcpForwarding no ForceCommand /usr/libexec/openssh/sftp-server # id playwithbits returns: uid=504(playwithbits) gid=504(playwithbits) groups=504(playwithbits),507(web-root-locked) I have changed the user's home directory to: home/nginx/domains/playwithbits/public Now when I attempt to sftp in with this user I instantly get the message: connection closed Does anyone know what I am doing wrong? Edit: Following advice from @Dennis Williamson I have connected in debug mode (I think... correct me if I'm wrong). I have made a bit of progress by using chmod to set permissions recursively of all files in the directly to 700.

• bash profile works for user but not sudo

  - by user564448

  I've modified my .profile to include a folder if a flash drive is plugged in. When running the command as the user it works fine but tells me the scrip must be run by sudo (this is what i want). However, when i try to run it with sudo i get "command not found" I have a symlink (flash) in my /var/www folder pointing to my /media/flash drive. (nevermind this setup since is just for dev) this is my user's .profile : # set PATH so it includes flash scripts if [ -d "/var/www/flash/scripts" ] ; then PATH="/var/www/flash/scripts:$PATH" fi when trying to run as sudo i get: sudo: script: command not found any ideas?

• How do game programmers design their classes to reuse in AI, network and play and pass mode?

  - by Amogh Talpallikar

  For a two player game where, your opponent could be on the network, CPU itself or near you where you would play turn by turn on the same machine. How do people design classes for re-use ? I am in a similar situation and have no experience in making such complex games. But here is what I have thought, If I am a player object , I should only be interacting with the GameManager or GameEngine Singleton , from which I will get various notifications about the game status. I dont care where and who my opponent is, this GameManager depending upon the game mode, will interact with gameNetworkManager , or AI tell me what the opponent played. I am not sure about the scenario where we play and pass [turn by turn on same machine]. Hoping for a brief but clear explanation or at least a link to a similar resource.:)

• Books or help on OO Analysis

  - by Pat

  I have this course where we learn about the domain model, use cases, contracts and eventually leap into class diagrams and sequence diagrams to define good software classes. I just had an exam and I got trashed, but part of the reason is we barely have any practical material, I spent at least two good months without drawing a single class diagram by myself from a case study. I'm not here to blame the system or the class I'm in, I'm just wondering if people have some exercise-style books that either provide domain models with glossaries, system sequence diagrams and ask you to use GRASP to make software classes? I could really use some alone-time practicing going from analysis to conception of software entities. I'm almost done with Larman's book called "Applying UML and Patterns An Introduction to Object-Oriented Analysis and Design and Iterative Development, Third Edition". It's a good book, but I'm not doing anything by myself since it doesn't come with exercises. Thanks.

• Make my website dynamically loaded data available to Facebook Open Graph Object Scrapper

  - by fvaliquette

  Here is the design of my web site: The user enter myWebsite.com/a/1 .htaccess rules redirect to myWebsite.com/b Now the JavaScript ExtJS library is loading. Extracting the value from the URL (in this case it is “1”) Loading ./xml/1.xml From 1.xml setting the Open Graph data (Title, type, image, etc) Loading data that will be shown to the user from 1.xml into the website. My question is: How can I make the Open Graph data available to Facebook? Facebook do not to load my ExtJS JavaScript Library before extracting the Open Graph Object values from the HTML. Is there an easy solution to this problem? The only solutions I found is to make statics web pages or dynamically pages rendered on the server side but I would like to avoid these since my web page implementation is already finished and I would like to avoid re working on it.

• Simulating an object floating on water

  - by Aaron M

  I'm working on a top down fishing game. I want to implement some physics and collision detection regarding the boat moving around the lake. I would like for be able to implement thrust from either the main motor or trolling motor, the effect of wind on the object, and the drag of the water on the object. I've been looking at the farseer physics engine, but not having any experience using a physics engine, I am not quite sure that farseer is suitable for this type of thing(Most of the demos seem to be the application of gravity to a vertical top/down type model). Would the farseer engine be suitable? or would a different engine be more suitable?

• How to make the transition to functional programming?

  - by tahatmat

  Lately, I have been very intrigued with F# which I have been working a bit with. Coming mostly from Java and C#, I like how concise and easily understandable it is. However, I believe that my background with these imperative languages disturb my way of thinking when programming in F#. I found a comparison of the imperative and functional approach, and I surely do recognize the "imperative way" of programming, but I also find it difficult to define problems to fit well with the functional approach. So my question is: How do I best make the transition from object-oriented programming to functional programming? Can you provide some tips or perhaps provide some literature that can help one to think "in functions" in general?

• Dynamic User Specific CSS Selection at Run Time

  I had a cool question while I was at MIX. A developer needed the ability to have his site render pages using a CSS file selected based on some user specific criteria. ASP.NET 4 controls generate CSS friendly output and more and more we web developers are using CSS for layout etc. Using multiple CSS files in our site wide templates we can not only provide different aesthetic experiences but we can chage the style based on the device type (Printer ot Phone) or the special needs of the end user...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• What is Object Oriented Programming ill-suited for?

  - by LeguRi

  In Martin Fowler's book Refactoring, Fowler speaks of how when developers learn something new, they don't consider when it's inappropriate for the job: Ten years ago it was like that with objects. If someone asked me when not to use objects, it was hard to answer. [...] It was just that I didn't know what those limitations were, although I knew what the benefits were. Reading this, it occurred to me I don't know what the limitations or potential disadvantages of Object-Oriented Programming are. What are the limitations of Object Oriented Programming? When should one look at a project and think "OOP is not best suited for this"?

• Using Validation Groups Inside ASP.NET User Controls

  - by bipinjoshi

  Validation groups allow you to validate data entry controls in groups. Server controls such as validation controls, Button and TextBox have ValidationGroup property that takes a string value. All the server controls having the same ValidationGroup value act as one validation group. Validation groups come handy in situations where you wish to validate only a small set of controls from many controls housed on a Web Form. Using validation groups is quite easy and straightforward. However, if you have a validation group inside a user control and there are more than one user control instances on a Web Form you face some problem.http://www.binaryintellect.net/articles/13427d3d-1f98-4dc0-849b-72e95b8b66a2.aspx

• Why are most GNU's software written in C

  - by BallroomProgrammer

  I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?
