• How can I make the boostrap js carousel automatically cycle as soon as the page loads?

  - by Jonathan Larkin

  Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

• What technology(s)would be suitable for the front end part of a Java web game?

  - by James.Elsey

  As asked in a previous question, I'm looking to create a small MMO that will be deployed onto GAE. I'm confused about what technologies I could use for the user interface, I've considered the following JSP Pages - I've got experience with JSP/JSTL and I would find this easy to work with, it would require the user having to "submit" the page each time they perform an action so may become a little clumsey for players. Applet - I could create an applet that sits on the front end and communicates to the back end game engine, however I'm not sure how good this method would be and have not used applets since university.. What other options do I have? I don't have any experience in Flash/Flex so there would be a big learning curve there. Are there any other Java based options I may be able to use? My game will be text based, I may use some images, but I'm not intending to have any animations/graphics etc Thanks

• What are the Search engine affects of registering the same domain on multiple top level domains (ie. .com, .ie, .nl etc.)?

  - by user1020317

  I'm looking to register a few more domains for my company, I have my-company.com at the moment, but now require my-company.com.au and my-company.nl and some others.. I'm running through my options and wondering what is the best.. Duplicate all the content on the .com package and make a replica at the other domains Buy the other domains but do a 301 redirect back to the .com domain. Create a full new website with different content for the new domains, thus having no text duplication We currently sell over the world so would like to raise our Search rankings in various countries, can this be done by buying the domain in the country, and if so, how will the above methods affect our search rankings. Any other suggestions are welcome!

• Weird keyboard problem

  - by Sebastian

  I just installed Ubuntu on an Acer Extensa 5620 laptop. The keyboard works fine except when I want to type things that require me to use Ctrl+Alt+(any key). I can't use Ctrl+Alt+(any key) shortcuts in any program, but I can open terminal with Ctrl+Alt+T. Ctrl+(any key) and Alt+(any key) shortcuts seems to work though. Also I just installed the game Heroes of Newerth and neither Alt or Ctrl keys seem to work in the game. Any answer would be appreciated!

• jQuery: What listener do I use to check for browser auto filling the password input field?

  - by Jannis

  Hi, I have a simple problem that I cannot seem to find a solution to. Basically on this website here: http://dev.supply.net.nz/vendorapp/ (currently in development) I have some fancy label animations sliding things in and out on focus & blur. However once the user has logged in once the browser will most likely remember the password associated with the users email address/login. (Which is good and should not be disabled.) However I run into issues triggering my label slide out animation when the browser sets the value on the #password field automatically as the event for this is neither focus nor blur. Does anyone know which listener to use to run my function when the browser 'auto fills' the users password? Here is a quick screenshot of the issue:

• Flash Overlapping HTML. CSS Problem In IE??

  - by Jascha

  HELP, this is a very unique problem and I can't for the life of me figure it out. My flash content is overlapping the HTML above it. This only happens if I've just launched IE after being restarted and goes away once I refresh the page. I even added a jQuery $(document).ready function that sets a margin between the html and the flash content to add 1px of space when the page is loaded. It's so hard to figure out, because once I refresh the page, it goes away. Any input GREATLY appreciated. Here is the site. http://www.californiaremodels.com (This only happens in IE) here is a screen shot of the problem.

• MySQL/PHP: How to insert logged in user id into another table that is gathering data from a form tha

  - by Lisa

  For the first time I am needing to join information from two tables and am quite nervous about doing it without any advice first. Basically, I am building a secure site that is accessed by authorised users. I have my login table with user_id, username, password Once the user is on the site, they have the option of inputting data into another table called input. At the moment this table only captures the information that is entered, not the user_id or username of the inputter. I would like the form to be able to input the user_id and/or username from the login table into the input table. Please could somebody talk me through this process? I am sure that once this is amended, I will then be able to use the table to only allow the logged in user to access the information that he or she have inputted, is that correct? Many thanks

• Personal Activity Monitor tracks time you spend using desktop apps

  Up until a couple of years ago, I used to turn to RescueTime to figure out how I spend my time online. Then it got too complex, and I stopped using it. Personal Activity Monitor is like a vastly dumbed-down version of RescueTime, and I mean that as a compliment. It's free and bare-bones -- all it does is track what applications you're using and for how long. A big drawback at this point is that it doesn't integrate with Web browsers to help you analyze how you spend your time on the Web. Still, if your work doesn't require constant Web app use, knowing how long you've used a browser overall might be enough to help you manage your time. This is far from the only application in this space -- alternatives such as Slife and Chrometa are full-featured and impressive -- but PAM is good option for those who want a nice, simple tracker.Personal Activity Monitor tracks time you spend using desktop apps originally appeared on Download Squad on Sat, 05 Mar 2011 10:00:00 EST.

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• quickest way to research a set of pages backlinks

  - by JeremyB

  I have a list of 300+ pages (they were chosen based on which pages rank for a keyword I'm interested in) and I want to compile a list all the (known) inbound links to those pages. What's the fastest way to do this? It seems like the only tools out there-- Yahoo Site Explorer, SEOMoz, Majestic, require you to either a) manually export each set of links by hand, or b) get data at the domain level (e.g. Majestic's clique hunter). Does anyone know of any efficient way to do this? I ask because I'm about to write a bunch of code and I don't want to waste my time if there's another tool that will work. I know SEOMoz and Majestic have API's but I'm wondering if there's a more user-friendly option.

• conditional while loop in php?

  - by julio

  I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

• Can a domain specific language be used to representing the Open SRD

  - by NeoModulus

  I am in the early stages of creating an open source C# library that would allow developers to drop in the open SRD (http://www.d20srd.org/) into an existing project. Abstracted it is a complex set of tightly coupled business rules. Having previously worked on an adaptive object model project for health care risk management I began with that pattern in mind. Due to the high coupling of rules it is becoming apparent that the project may require some kind of scripting. Have started researching DSL implementation I am now considering scraping the adaptive object model for a domain specific language. I have not work with domain specific languages so my question is it reasonable to assume a domain specific language can be used to representing the open SRD?

• Static variable for optimization

  - by keithjgrant

  I'm wondering if I can use a static variable for optimization: public function Bar() { static $i = moderatelyExpensiveFunctionCall(); if ($i) { return something(); } else { return somethingElse(); } } I know that once $i is initialized, it won't be changed by by that line of code on successive calls to Bar(). I assume this means that moderatelyExpensiveFunctionCall() won't be evaluated every time I call, but I'd like to know for certain. Once PHP sees a static variable that has been initialized, does it skip over that line of code? In other words, is this going to optimize my execution time if I make a lot of calls to Bar(), or am I wasting my time?

• What Does It Usually Mean for a Feature to be "Supported"?

  - by joshin4colours

  I'm currently working some testing for a particular area of an application. I had to write some automated tests for a particular feature but due to the circumstances, this was not easy to do. When I asked one of the other testers about it, he mentioned that the same features exist in a sister application our company produces but isn't documented anywhere (end-user documentation or otherwise). He also said that the feature doesn't typically get tested at all in the sister application and isn't usually tested in the application I work on. Apparently this feature isn't heavily used but removing it would require a fair bit of work so the benefit-cost ratio doesn't work out. All of this has left me with some questions. Other than "The documentation says so" or "We told the client it is", what usually makes a feature "supported" versus an unsupported feature?

• Classless tables possible with Datamapper?

  - by barerd

  I have an Item class with the following attributes: itemId,name,weight,volume,price,required_skills,required_items. Since the last two attributes are going to be multivalued, I removed them and create new schemes like: itemID,required_skill (itemID is foreign key, itemID and required_skill is primary key.) Now, I'm confused how to create/use this new table. Here are the options that came to my mind: 1) The relationship between Items and Required_skills is one-to-many, so I may create a RequiredSkill class, which belongs_to Item, which in turn has n RequiredSkills. Then I can do Item.get(1).requiredskills. This sounds most logical to me. 2) Since required_skills may well be thought of as constants (since they resemble rules), I may put them into a hash or gdbm database or another sql table and query from there, which I don't prefer. My question is: is there sth like a modelless table in datamapper, where datamapper is responsible from the creation and integrity of the table and allows me to query it in datamapper way, but does not require a class, like I may do it in sql?

• Restricting A Directory Through .htaccess

  - by Whitechapel

  I'm trying to put all of my FTP accounts into a folder on /public_html/ftp and password protect it so search bots can't crawl their private files. I'm also trying to redirect all site traffic from the non-www to www. I keep getting 500 errors when accessing the site, and I need to point it to www.vivalanation.com/ftp to www.vivalanation.com/ftp/, because the /ftp just errors out, you need the trailing slash. Here is my .htaccess in the /public_html/ftp folder: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] AuthName "FTP Access" AuthType Basic AuthUserFile /home1/vivalst/.htpasswds/public_html/ftp/passwd Require valid-user I created a passwd file in /.htpasswds/public_html/ftp And here is my basic .htaccess in the root of /public_html/: RewriteEngine on RewriteBase / RewriteCond %{HTTP_HOST} !^www\.

• How can a regular user be notified of a required reboot?

  - by Andre

  I am administrating multiple machines on which I am admin and the users have not admin-rights. The machines are configured to pull and install updates automatically. A new kernel will require a reboot. On Ubuntu Precise this was made visible to the user through the color change of the shutdown-menu in the upper right corner (it turned red). Now, on Ubuntu Trusty, there is not color change anymore. Also, the Update Manager will not pop up for regular users reminding them of an outstanding reboot. How can a regular user know that a reboot is required?

• Do ALL your variables need to be declared private?

  - by shovonr

  I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly loose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

• Button in App on iOS 4.2 won't work properly

  - by MatthiasC

  My app, written for the iPad contains several UIButtons. One of them starts and stops an AVAudioPlayer: hitting the button once starts the player, hitting it again stops it accordingly. Rinse and repeat. This all works nicely on iOS version pre 4.2. When installing the App on an iPad with iOS 4.2, the button turns on and off the audio player exactly once, then stops working properly: after hitting the button, it turns into its selected state, but it does not start the audio player (as it should) and hitting the button again doesn't return it to its default state, either. As previously said: it's all fine and dandy pre 4.2, the problem only arises on the most current OS version. XCode 3.2.4 iPad with iOS 4.2

• How would you tackle a pattern-finding program?

  - by Neil

  Just to be clear, I don't think this should be question better suited for stackoverflow.com simply because there's not a single answer but a wide range of possible solutions, making this question far more subjective in nature. I was curious how you guys would tackle a pattern-finding program, which is to say I'd do the following operations: I enter in some input. Program predicts my next input based on all previous inputs. Rinse. Repeat. Since the amount of input I could provide is so varied, including empty strings, conventional means such as switches or regular expressions are out, since it would require you to have an inkling of information about what to expect. I was thinking about some form of genetic algorithm, yet even then I don't have a clue as to how to approach a problem of this caliber. I think some feedback mechanism would be necessary as well as to let the program know how close it was. Anyone had to do a similar type program before?

• system-wide hook for 64-bit operating systems

  - by strDisplayName

  Hey everybody I want to perform a system-wide hook (using SetWindowHook) on a 64bit operating system. I know that 64bit processes (= proc64) can load only 64bit dlls (= dll64) and 32bit processes (= proc32) can load only 32bit dlls (= dll32). Currently I am planning to call SetWindowHook twice, once with dll32 and once with dll64, expecting that proc64s will load dll64 and proc32s will load dll32 (while dll32 for proc64s and dll64 for proc32s will fail). Is that the correct way to do that, or is there a "more correct" way to do that? Thanks! :-)

• getting rid of repeated customer id's in mysql query

  - by bsandrabr

  I originally started by selecting customers from a group of customers and then for each customer querying the records for the past few days and presenting them in a table row. All working fine but I think I might have got too ambitious as I tried to pull in all the records at once having heard that mutiple queries are a big no no. here is the mysqlquery i came up with to pull in all the records at once SELECT morning, afternoon, date, date2, fname, lname, customers.customerid FROM customers LEFT OUTER JOIN attend ON ( customers.customerid = attend.customerid ) RIGHT OUTER JOIN noattend ON ( noattend.date2 = attend.date ) WHERE noattend.date2 BETWEEN '$date2' AND '$date3' AND DayOfWeek( date2 ) %7 >1 AND group ={$_GET['group']} ORDER BY lname ASC , fname ASC , date2 DESC tables are customer-customerid,fname,lname attend-customerid,morning,afternoon,date noattend-date2 (a table of all the days to fill in the blanks) Now the problem I have is how to start a new row in the table when the customer id changes My query above pulls in customer 1 morning 2 customer 1 morning 1 customer 2 morning 2 customer 2 morning 1 whereas I'm trying to get customer1 morning2 morning1 customer2 morning2 morning1 I dont know whether this is possible in the sql or more likely in the php

• what is main focus for a developer when coding?

  - by ajsie

  i read a lot of books about how to code right and usually the are talking about all these techniques from a point of view i can't understand. eg. lets consider the singleton pattern. i'm restricting so the class can only be instantiated once. but since it's only me creating the application, if i know that the class only should be instantiated once, then why would i create it a second time? i feel like missing the big picture. what is my main goal when coding an application? how should i think? thanks
