• At what point should data be sent back to server?

  - by whamsicore

  A good example would be the stackexchange "rate" button. When a post is upvoted the arrow changes color immediately. However there is a grace period for one to edit one's vote decision (oops! voted by mistake?). Is the upvote action processed immediately or does is only process after a set time period, or when the user leaves the page? How exactly is this rating processed? What is the standard for handling dynamic page edits (e.g. stackexchange rating, facebook posts?)

• Revamped Joomla site to Google search engine

  - by user3127632

  I am about to upload a revamped site of Joomla (update from 1.5 to 2.5 + changes). I currently have a test bed subdomain that I am currently working on. In few days I am about to do the swap and replace the old site with the new one. I am worrying about Search Engines and specifically Google. The site currently has a very good rank (appears 2nd in the search), what actions do I have to take in order to be updated and preserve the rank? (except submitting the new sitemap I guess). It's not a difficult task but because I don't have the option to be wrong or mistakes to be done I an asking for a more "expert" advice.

• Dependency Injection Confusion

  - by James

  I think I have a decent grasp of what Dependency Inversion principle (DIP) is, my confusion is more around dependency injection. My understanding is the whole point of DI is to decouple parts of an application, to allow changes in one part without effecting another, assuming the interface does not change. For examples sake, we have this public class MyClass(IMyInterface interface) { public MyClass { interface.DoSomething(); } } public interface IMyInterface { void DoSomething(); } How is this var iocContainer = new UnityContainer(); iocContainer.Resolve<MyClass>(); better practice than doing this //if multiple implementations are possible, could use a factory here. IMyInterface interface = new InterfaceImplementation(); var myClass = new MyClass(interface); It may be I am missing a very important point, but I am failing to see what is gained. I am aware that using an IOC container I can easily handle an objects life cycle, which is a +1 but I don't think that is core to what IOC is about.

• Website inheritance of ownership question

  - by Adrian Denham

  I paid for a web site for my motel business, then due to my landlord actions I was placed in a position to file for bankrupcy. I asked my IT manager and web developer to close down the web site for the business. He has since then sold my web site to the new owners. I took all the photos myself and I am in at least 4 of the photos on the site. There are no changes to the site as I left it and it now states that it is under the copyright on the new owners? I am not sure what I should do as this happen 10 months ago and I have just found this out. Thank you for your help, I am in Australia.

• Legislative Alert - Payroll for North America

  - by Carolyn Cozart

  We have a Legislative Alert for our customers using PeopleSoft Payroll for North America.   The IRS has made some changes to the FUTA reporting for the tax year 2011.  The IRS requires that all employers complete the 940 Schedule A form when completing the Tax Form 940.  On the Schedule A employers must indicate every state in which you were required to pay state unemployment tax during the year (even if that state's credit reduction rate was zero).  For states with a credit reduction rate greater than zero you must enter the FUTA taxable wages paid in that state then multiply it by the credit reduction rate to report the credit reduction amount for that state.  Please go to Document ID 1371681.1 to obtain additional information on this regulation along with Oracle/PeopleSoft position on this new requirement.

• Has anyone used Sproutcore?

  - by Sam Lee

  Has anyone used Sproutcore for a web application? If so, can you give me a description of your experience? I am currently considering it, but I have a few concerns. First, the documentation is bad/incomplete, and I'm afraid that I'll spend lots of time figuring things out or digging through source code. Also, I'm a bit hesitant to use a project that is relatively new and could undergo significant changes. Any thoughts from people who have developed in Sproutcore are appreciated! EDIT/PS: Yes, I've seen this post: http://stackoverflow.com/questions/370598/sproutcore-and-cappuccino . However I'm interested in a bit lengthier description of Sproutcore itself from someone who's used it for a significant project.

• Application use on website

  - by Palmer

  Is there a good way to run a C# application on clientside in lieu of JavaScript? I have done some front end work with JavaScript and backend C# for web developing at an old job, but I am interested in hosting a website myself soon. I have a C# application I would like to be open source, but before people care to download I'd like them to be able to use it. At its basic level it's a simple text editor, but there's much more to it in the nitty gritty. I could write it in JavaScript, but it would require me to keep documentation and up to date changes on JavaScript and C# in that case. I was thinking of creating an AJAX panel and somehow loading my winform application into a frame, but I don't know how or what words to google because I've never done it before except AJAX.

• How to give control over keyboard back to X server after Alt + SysRq + R trick

  - by Øystein Tråsdahl

  Situation: an application freezes the X server and no keyboard input works. So I use Alt+SysRq+R to take the keyboard out of raw mode (make the kernel take control of the keyboard away from the X server). I can then type Ctrl+Alt+F1, kill the bad processes, and everything works again. So far so good. But the keyboard is still in the hands of the kernel, making Alt+Left/Right shortcuts for Decr_Console/Incr_Console. This is annoying, and I want to give control over the keyboard back to the X server. I have tried typing Alt+SysRq+R again, this does not switch things back. I have also tried the command kbd_mode -u, but nothing changes. Any advice?

• Is it a good practice to use branches to maintain different editions of the same software?

  - by Tamás Szelei

  We have a product that has a few different editions. The differences are minor: different strings here and there, very little additional logic in one, very little difference in logic in the other. When the software is being developed, most changes need to be added to each edition; however, there are a few that don't and a few that needs to differ. Is it a valid use of branches if I have release-editionA and release-editionB (..etc) branches? Are there any gotchas? Good practices? Update: Thanks for the insight everyone, lots of good answers here. The general consensus seems to be that it is a bad idea to use branches for this purpose. For anyone wondering, my final solution to the problem is to externalize strings as configuration, and externalize the differing logic as plugins or scripts.

• Is a finite state machine an appropriate solution for this situation?

  - by user1936

  I was writing some test code as an example where I had a washing machine class. It has a door state that should be open or closed, and also a running state, either on or off. I want to prevent the running state from changing from 'off' to 'on' when the door is 'open', and also prevent the door from being set to 'open' while the machine is 'on'. I have this functionality rigged up with a bunch of if statements. It feels inelegant and it could quickly turn into spaghetti code if I want to add another state that puts additional conditions on the changes of other states. I wonder, is a finite state machine a solution for this situation? Would it simplify adding states and defining valid transitions?

• Shelving code in TFS

  - by Mel

  I'm pretty new at using TFS and I'd like to know how you or your team use the "shelve" function of tfs. We have the following guidelines in using TFS: - perform a "Get Latest" before you check in and try to build/compile - do not check in code that does not compile - at the end of the day, if your work is not complete/partially done, you should "shelve" your pending changes The first two make sense but I don't really get the last one. I asked my mgr and he said that its so he knows that you actually did some work for that day, which does kind of makes sense but still, I'm wondering what other teams use the "shelve" function for?

• We have a 200% increase of "organic" search traffic - how to figure out which keyword is causing this?

  - by Robert Grezan

  So our Google Analytics are showing us that 200% increase of "organic" search traffic. Analytics are saying that search keyword is "(not provided)". We are wondering how to find out which keyword is causing this? We are monitoring all important keywords for our website. None of keyword is in first 5, so our "organic" serach traffic is modest. However, today we received 200% increase of "organic" search traffic but none of keywords we can think of moved a bit. We also did not change anything related to SEO. And what is interesting Google Webmaster shows no changes - ~2500 impressions and ~200 clicks. How to find out which "keyword" might be causing this spike?

• What steps/tools/apps are necessary to make local php development on a tablet viable?

  - by Tchalvak

  I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

• redefine shortcuts for keys being set to default after reboot

  - by MYA

  i am using PHPStorm editor on Ubuntu 14.04. Everything is so smooth that I am loving the experience (especially the workspace experience is amazing) however this bug is giving me headache... some of the editor's short-cuts clash with default Ubuntu keys (Alt + Ctrl + Left,Right,Up or Down arrow keys). I have changed the default keys to (super + Left,Right,Up and Down arrow keys) so they don't collide with my editor but after the reboot, Ubuntu changes are somehow reverting to default. This keeps comming again and again. i am sure there is a way out so therefore need help with that...

• Offline apt-get update to age of cache

  - by James Haigh

  I have a script to quickly upgrade a Live or fresh system from cached files on a flash drive. In essence, it looks like this: # *Code to remove and symlink /var/cache/apt/ if currently empty of packages.* sudo apt-get dist-upgrade # Quick offline cached upgrade; not limited by slow WANs. echo $'\nMake sure Internet is reachable and press enter for complete online upgrade.'; read sudo apt-get update sudo apt-get dist-upgrade # Complete online upgrade. The problem is that the ‘cached upgrade’ seems to ignore the cached pkgcache.bin and srcpkgcache.bin which is where I assume apt-get update stores its changes, so the upgrade completes as if the system is up-to-date. Useless. So in that case, I need some code to apt-get update to the age of the package cache on my flash drive. This code would be placed between the 1st and 2nd lines of the code above.

• Wireless network unstable and often WPA2 protected networks just don't work

  - by Pedro

  I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.

• Unity greeter background not changing for users automatically after upgrade

  - by bioShark

  I have recently upgraded from 11.10 to 12.04. Normal upgrade, no new installation. In 11.10 I was using Simple LightDM Manager tool to set a custom wallpaper on the login screen. This tool unfortunately doesn't seem to do anything since I have upgraded. I have also heard that 12.04 is suppose to have this feature (changing login wallpaper per different user) by default. I have searched in settings but unfortunately in vain. So, to keep it short, could somebody direct me to the option(s) page where I can make the desired changes.

• How do I toggle sound with amixer?

  - by joschi

  Including Natty I was always able to toggle (mute/unmute) the 'Master' sound volume with the amixer sset Master toggle command that I linked to an edge binding in CompizConfig-Manager. Now after installing Oneiric the command only mutes the sound but doesn't unmute it. I even tried it in the Terminal but it also doesn't work. It changes 'Mono: Playback 68 [78%] [-14.25dB] [off]' to '...[on]' but the sound stays muted so that I have to unmute it via the 'sound-indicator' in the panel. How can I get this working again? What did change since Natty? Does anyone know the command the 'sound-indicator' uses to toggle the sound volume?

• Is it possible to transfer Google Authorship?

  - by Stephanus Yanaputra

  Is it possible to transfer Google Authorship from one account to another? Scenario: I have user A who is a legitimate Google Author in my WordPress site. When I search the 'keyword' in Google, his name and photo will show up in the search result. One day A left the company, so we don't want to use his name again as an author, and transfer it to another person which is B. Technically speaking, I can just alter the display name and Google+ Profile URL of A to B. And then I probably can notify Google of the changes happening. But what will happen then? Will Google get confused and think that I'm doing scam? Is doing this action even correct in the first place?

How can I force that text to stay white in the theme files? (See the linked question above for a reference as to what changes I made; everything else is the same as regular Ambiance.)

• How to make Pokémon White 3D effect?

  - by Pipo

  I just wondered how to create a 3D effect similar to Pokemon White/Black? It seems to be not polygon based, but created just with sprites. If the perspective changes the sprites stay sharp and don't get blurred. How can I archive this? Source: https://www.youtube.com/watch?v=fZEPUPYOnRc&feature=youtube_gdata_player Edit: Wow, two downvotes because I used a video instead of screenshots? Don't get me wrong, I thank you, because you want to help me, but the 3D effect can be better understand in motion. Anyway, here is a screenshot: http://wearearcade.com/wp-content/uploads/2011/03/pokemon-black-white-starter-town.jpg So, if this is a hardware limitation, how can I archive this o na different hardware, e.g. a HTML5 game? Thank you.
