• Change the output of the facebook like button [migrated]

  - by Mechaflash

  I've tied in the code for the facebook like button from the facebook dev site (I currently use the iframe version) directly into the html of a node (or content post). I want to be able to manipulate what text is sent when someone hits the like button. you can see the site and buttons here www.masteringmoneybasics.org I've tried both the iframe and html5 versions of the button and can't see where to alter what is sent. If there is no way to directly alter what is sent, does anyone know what it looks for in content to be sent so I can structure the node correctly? If you notice, when you like the page, it doesn't get the first sentence of the content, but all content after it, and I've tried putting different content in between the two lines (in its own <p>) and it still grabs the latter. Also how it figures out which image to grab from the page? Most times it doesn't take any image, however twice it's grabbed the middle school image.

• Main class passes dbConn obj to all its services, I need to change the dbConn for one of its services. - suggestion for design pattern

  - by tech_learner

  There is this main class and there are several services ( which uses db connection to retrieve data ) These services are initialized in the main class db properties are obtained from the property file and then dbconnection is opened by calling a method dbOpen() written in the main class and the resultant connection object is set to the service objects by iterating through the list of services and by calling setConnection method on the service note: that the services are instantiated in the main class and the main class is not a superclass for services. I also need to mention that there is this recycle db connection scenario only main class is aware of. /** connects to DB, optionally recycling existing connection), * throws RuntimeException if unable to connect */ private void connectDb(boolean recycle) { try { if (recycle) { log.status( log.getSB().append("Recycling DB Connection") ); closeDb(); } openDb(); for ( int i = 0 ; i < service.length ; i++ ) { service[i].setConnection(db); } } One of the service needs to use a different database, what is the best design pattern to use?

• Is there a phrase or word to describe an algorithim or program is complete in that given any value for its arguments there is a defined outcome?

  - by Mrk Mnl

  Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a defined outcome? i.e. all the ramifications have been considered whatever the context? A simple example would be the below function: function returns string get_item_type(int type_no) { if(type_no < 10) return "hockey stick" else if (type_no < 20) return "bulldozer" else return "unknown" } (excuse the dismal pseudo code) No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here: "get_item_type() is ______ complete" ? (The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).

• How to reverse engineer the SEO on a website?

  - by Startup Crazy

  I have read this question. My question is a bit different from it. I want to know how can I reverse engineer another website that is ranking the best for some keywords. For example some website called www.bla.com is there and it ranks high for many keywords and I want to learn from it how can my website be of the same authority and get the same ranking (or probably better ranking if I found something that they are missing). Can anyone enlist it as a procedure, how to reverse engineer a website?

• How can I learn to write idiomatic C++?

  - by yati sagade

  I am a computer science student, and as a result, I was taught C++ as a better version of C with classes. I end up trying to reinvent the wheel whenever a solution to a complex problem is needed, only to find sometime after that, some language feature or some standard library routine could potentially have done that for me. I'm all comfortable with my char* and *(int*)(someVoidPointer) idioms, but recently, after making a (minor) contribution to an open-source project, I feel that is not how one's supposed to think when writing C++ code. It's much different than C is. Considering that I know objected-oriented programming fairly well, and I am okay with a steep learning curve, what would you suggest for me to get my mind on the C++ track when I'm coding C++?

• Efficient Bus Loading

  - by System Down

  This is something I did for a bus travel company a long time ago, and I was never happy with the results. I was thinking about that old project recently and thought I'd revisit that problem. Problem: Bus travel company has several buses with different passenger capacities (e.g. 15 50-passenger buses, 25 30-passenger buses ... etc). They specialized in offering transportation to very large groups (300+ passengers per group). Since each group needs to travel together they needed to manage their fleet efficiently to reduce waste. For instance, 88 passengers are better served by three 30-passenger buses (2 empty seats) than by two 50-passenger buses (12 empty seats). Another example, 75 passengers would be better served by one 50-passenger bus and one 30-passenger bus, a mix of types. What's a good algorithm to do this?

• GUI won't load, but the desktop background loads. Can't access the terminal

  - by Mickeysofine

  Having trouble with the Ubuntu GUI. I can log in just fine (see this)... everything looks normal there. But as soon as I put in my password, I get this. I tried a few different troubleshooting keyboard commands (ctrl+alt+t, crtl+alt+delete), and only the latter worked. I can interact with that window just fine, except I am unable to resize or move it. The first time I logged in, I got a dialog box that said, "Ubuntu has experienced an internal error. Send error report?" Doesn't say anything now. Yes I tried restarting it. Thanks a bunch, Michael EDIT: Trying to start a guest session leads to the same problem.

• Triple Monitor Setup with Nvidia and Compiz

  - by AndrewX192

  I have a triple monitor setup with two video cards on Ubuntu 10.04. I have the monitors and graphics cards currently setup as follows: Nvidia Geforce 210 #1 - 1920x1080 Monitor (Twinview) [Center - Monitor #1] - 1920x1080 Monitor (Twinview) [Right - Monitor #2] Nvidia Geforce 210 #2 - 1920x1080 Monitor (Separate X Screen) [Left - Monitor #3] This works fine, except when I open a program, it shows up in between monitor #1 and #2 - meaning I have to drag it to one screen before I can use the window. Gnome2's gnome-panel also does not work on the twinview setup; it spans between both monitors, but it does not redraw (ex: the clock never changes). In addition, when I maximize an application, it spans both monitors, which is not acceptable. When I enable Xinerama for my setup, gnome-panel no longer spans two monitors, and applications maximize as expected, but compiz does not work, as X11 compositing is not available. The lack of desktop compositing causes problems with dragging windows between screens (redraws take forever). Is there anything I can do to fix these issues without opting for different graphics cards?

• Many ui panels needs interaction with same object

  - by user877329

  I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

• Creating several instances of the same object, and selecting only one

  - by hustlerinc

  I'm playing around with making a puzzle game, haven't done that much before I run into my first problem. Basically, I want to create a certain amount of the same object/function. But without hardcoding the different instances. I think maybe an array is a good idea? and then a for loop to push the objects in? And then I need to be able to select one of these objects by clicking on it, how would I do that? How do I know which ball in the array was clicked? A loop again? I made a jsFiddle example (you need to click the orange ball to select, then you can move it around by clicking the canvas). This is what I want to do, but with more balls. How would you solve this? Help appreciated.

• Segment subdomains with Google Analytics?

  - by andrewpthorp

  So, when a website has multiple subdomains: www.example.com foo.example.com bar.example.com What is the best way to use Google Analytics to segment the data? I would prefer have access to 'All Data', 'Data from foo.example.com', and 'Data from bar.example.com'. I tried setting up 3 different views, and setting a filter on the foo/bar views that says: Include only traffic from the ISP domain that are equal to foo.example.com. However, I am not seeing any data collected into that View. I do, however, see all data in the 'All Data' view, but I can't figure out how to segment the data. I am including the analytics.js in the application.haml layout, which is always loaded in this app. Thanks!

• Installing multi-boot Linux system

  - by user94924

  I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

• wordpress login encryption

  - by tech

  I am running wordpress with woocommerce and theme_my_login plugins. When a user registers on my site it sends them a confirmation email and then they can click to activate account. Problem is when the user goes to login they get an error of incorrect password. If the user uses the forgot password link and resets the password then they can login without any errors. What might cause this problem? Is the password being encrypted with the wrong method? I went through the registration process and checked the string in the php users table. password in php table after registration: $P$BF/gIt6dFfBBuNx6rP41Qv3i71TUie1 password in php table after change password to same password: $P$BxpByDbNU3vr3sytTOcbzttp1tOodH1 Do Theme my login and either woocommerce or wordpress use different encryption methods?

• SIP clients not working on Ubuntu 12.04

  - by Xlearner

  I am trying to find a SIP client that works on Ubuntu 12.04. I have an account on voipdiscount (www.voipdiscount.com) and 12voip (www.12voip.com) Earlier on Ubuntu 11.10, I was able to use SIP clients: Twinkle, SFL Phone. Using these clients, I was able to access my account and make the phone calls to different destinations. But after I installed 12.04, Twinkle, SFL Phone and Ekiga stopped. Whenever I try to make a phone call using one of these software, for some reason they are not able to register. They are failing. Any suggestions as to what I can do? Is there any SIP client that works on Ubuntu 12.04? Thanks!

• usb keyboard stopped working in terminal window after update from 13.04 to 13.10

  - by Jim

  When I start the computer, I am logged in automatically. Using the keyboard, I type Ctrl+Alt+t, which brings up a terminal window, just like it should; however, nothing happens when I attempt to type into the terminal. If I change over to the guest account, I can type into the terminal, but (different problem here, I'll ask it separately unless someone is kind enough to answer it here) my password doesn't work for sudo or anything else. Elsewhere I read that Language support could fix it, but that won't accept my password either - and no, I haven't changed it lately. Also, my Plex Media Server seems to have disappeared. I'll re-install everything if necessary, but I sure would rather avoid that if possible

• How to deploy a single website to multiple physical servers.?

  - by user70122

  I want to deploy my PHP and Ajax based Dating website to multiple physical servers. Does anyone know the method. Is there possible any method to save the files and setting (and also the user input), on all of the physical server, so that the servers do the following jobs. Servers used as a network, speeding up the process giving a robust thing to the end user. Data to be stored on all the servers' hard drivers, and Every server have the internet connection from different provider, so for example a. if any of the internet providers gets down, or b. there occur any hardware or power failure, the website still runs, without a break and without any data loss. Does anyone know about some online course, or some comprehensive tutorials about this topic ?

• Accessing Master Page Controls

  - by Bunch

  Sometimes when using Master Pages you need to set a property on a control from the content page. An example might be changing a label’s text to reflect some content (e.g. customer name) being viewed or maybe to change the visibility of a control depending on the rights a user may have in the application. There are different ways to do this but this is the one I like. First on the code behind of the Master Page create the property that needs to be accessed. An example would be: Public Property CustomerNameText() As String     Get         Return lblCustomerName.Text     End Get     Set(ByVal value As String)         lblCustomerName.Text = value     End Set End Property Next in the aspx file of the content page add the MasterType directive like: <%@ MasterType VirtualPath="~/MasterPages/Sales.master" %> Then you can access the property in any of the functions of the code behind of the aspx content page. Master.CustomerNameText = “ABC Store” Technorati Tags: ASP.Net,VB.Net

• How to install ubuntu 12.04

  - by William A. Jordan

  I've had ubuntu on my pc for about 5 years,after the new 12.04 version and a day and a half trying to get it to just boot up. I will take it off my pc and rely on windows. I have 5 pc's which I built and am not an amateur, After installing it numerous times and even to run it from your webpage (to no avail). Granted I do have nvidia drivers on it, but after I went to their webpage and downloaded and installed the linux driver it,it still would not boot, by the way I took 2 different pc's apart and used what I thought were compatible (I shouldn't have to do this) parts. I have it on a seperate hd which I will remove and format. Have a nice day and so long (2 much trouble).

• Ubuntu 13.10 Installer freezes on partition recognition on Alienware M17x

  - by Mutewinter

  I'm trying to install Ubuntu 13.10 on an Alienware M17x, after bypassing the graphical problems with "nomodeset" (annoying!), I'm facing a rather different problem: I click on "Install Ubuntu", the guided installation progress reach the point where the partition, mount point etc. needs to be selected and...nothing. In the partition selection menu it sees only dev/sda, but in the window where the actual way the disk is partitioned should appear nothing shows, it's blank. I've tried to click on "change..." to try to force it to read something, but the installer simply quits. The button "change partition table" etcetera are greyed out (well, obviously, since no partition table has been read). What's that? The Alienware has Windows 7 and legacy BIOS (so no UEFI here). Anyone has an idea? Thanks for your time and help!

• Is How the Company Makes Its Money One of The Most Important Determining Factors in their work environment, culture, etc

  - by programmx10

  This is a viewpoint I've started to realize recently about some companies that I have worked for. They had their own software product that they developed in-house but most of the focus was on building an in-person sales team to push their product to businesses throughout the country. I figure that companies that are exclusively "online", meaning that their revenue source comes from online transactions where there is no "face" of the company to the customer would have a different work culture. Just curious if anyone has worked for both types of companies and notices a difference. I myself am hoping to get more into contract programming and figure that companies that don't have to employ a sales-force and things like that would be more focused on technology and maybe even willing to be flexible on partial telecommute, etc

• Rythmbox library set to: multiple locations and no way to edit/change

  - by Pierre

  I previously set Rhythmbox to include a few different locations. Now following changes to my directory structure, I'd like to reflect these changes in Rhythmbox. But when I go to "Library Location", I see "Multiple locations Set" and I can only add to the list; no way to edit/remove. I Googled this problem and the only relevant results I get date back to 2006, probably referring to a previous version of Rhythmbox and specifying components/locations that I can't find on my system. Give a look at the documentation...kind of minimal. Any clues? Ubuntu 12.04 Rhythmbox 2.96

• Is there any map maker for javaME game?

  - by user1494517

  For the past two weeks I was trying to make a map maker for my java ME 2D RPG game. I failed because i get errors using slick TWL and the forum for this is inactive. So I just wondered is there anyone that knows slick TWL (Themable Widget Library)? Or maybe do you know a good MapMaker where i could upload my map elements build a map and get numbers to use them for building map with LayerManager class? Already found one http://sourceforge.net/projects/tilemapeditor2d/. But the thing is my map elements are in different .png images. In one of those images there is 16 elements (trees water and etc) and those kind of images are 29. So it would be hard to build a map with LayerManager Well I was thinking putting everything into one image and that way it would be simplier.

• Help! Installer crashing

  - by Mike

  I had ubuntu 12.04 installed on a Satellite l635. I wanted to start over with a fresh install because I had experimented with a bunch of different things, and computer was getting glitchy and random freezes. I used the same iso I used for original install, and it keeps say the installer crashed with a erron5 input/output error. Tried an older iso for 11.10 I had used in the past with same issue... To see if it was disc or computer (not a great idea) I tried the 12.04 iso on another laptop. Now I have 2 laptops with no os. Both discs however live boot on both systems. PLEASE HELP! I've searched forums and can't find the same problem.
