  • Should I ditch AJAX in client side web development when I've got a web-socket open?

    - by jt0dd
    I was thinking that maybe I should forget AJAX (HTTP) requests when I've got a web-socket open between client and server, but I decided I should ask here to check if this could be a bad practice for some reason that I'm not thinking of. Once the socket is open, there's less syntax (often meaning simpler error handling) involved in passing information between client and server with Socket.io (just one example of a web-socket). Is there some obvious situation where a web-socket (Socket.io for example) isn't going to be capable of handling a functionality that an AJAX request could do easily?

  • How to fo fluid dynamics like Where's My Water?

    - by Edgar Miranda
    There is a game on the app store called "Where's My Water" that is really fun and uses fluid dynamics in it's gameplay. You can check out a video of the game play here... http://www.youtube.com/watch?v=UnFFWnwOohk. You use your finger to remove dirt from the screen, and then the water just flows to the new area. Anyone know what engine this was made in and how they where able to get the fluid dynamics in there? I'm using the Corona SDK for mobile development and want to do something similar like this (a game with fluid dynamics).

  • How does a search functionality fit in DDD with CQRS?

    - by Songo
    In Vaughn Vernon's book Implementing domain driven design and the accompanying sample application I found that he implemented a CQRS approach to the iddd_collaboration bounded context. He presents the following classes in the application service layer: CalendarApplicationService.java CalendarEntryApplicationService.java CalendarEntryQueryService.java CalendarQueryService.java I'm interested to know if an application will have a search page that feature numerous drop downs and check boxes with a smart text box to match different search patterns; How will you structure all that search logic? In a command service or a query service? Taking a look at the CalendarQueryService.java I can see that it has 2 methods for a huge query, but no logic at all to mix and match any search filters for example. I've heard that the application layer shouldn't have any business logic, so where will I construct my dynamic query? or maybe just clutter everything in the Query service?

  • Google is not treating two Austrailian schools as separate sites when both are subdomains of qld.edu.au

    - by LuckySpoon
    My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

  • Run Oracle E-Business Suite Period Close Diagnostic

    - by Get Proactive Customer Adoption Team
    Untitled Document Be Proactive & Save Time—Use the Period Close Diagnostic During the Month Have you ever closed your books at the end of the month and, due to problems with your Oracle E-Business Suite Period Close, you found yourself working all night or all weekend to resolve your issues? You can avoid issues by running the Oracle E-Business Suite Period Close Diagnostics throughout the month, prior to closing Oracle Financial Assets, General Ledger, Payables, and/or Receivables. You can identify issues that will interfere with your period close early, preventing last minute fire drills. Correct your errors or, if you need Oracle Support’s assistance, attach the output to a service request for faster resolution by the support engineer. Oracle E-Business Suite Diagnostics are included in your Oracle Premier Support agreement at no extra charge. They are proactive, easy to use, tools provided by Oracle Support to ease the gathering and analyzing of information from your E-Business Suite, specific to an existing issue or setup. Formatted output displays the information gathered, the findings of the analysis, and the appropriate actions to take if necessary. These tools are designed for both the functional and technical user, providing no EBS administration features, so you can safely assign this responsibility to users who are not administrators. A good place to start with the Support Diagnostics is the install patch Note 167000.1. Everything you need is in this patch and you install it on top of your E-Business Suite. If you are on EBS 12.0.6 or below, Oracle delivers the diagnostic tests in a standard Oracle patch and you apply it using the adpatch utility. If you are on EBS release 12.1.1 or above, your diagnostics are already there. Oracle E-Business Suite Diagnostics: Prevent Issues—resolving configuration and data issues that would cause processes to fail Identify Issues Quickly—resolving problems without the need to contact Oracle Support Reduce Resolution Time—minimizing the time spent to resolve an issue by increasing support engineer efficiency In the example below, you will see how to run the EBS Period Close Diagnostic step-by-step using an SQLGL Period Closing Activity Test. This allows you to check throughout the month to identify and resolve any issue that might prevent closing the period in the General Ledger on schedule.   Click the Select Application button. Select your Application. In this example, we will use the Period Close test. Scroll down to Period Close Place a check mark in the Period Closing box in the Select column. Click the Execute button at the bottom of the page Input the parameters. Click the Submit button Click the Refresh button, until the Status of the test changes from “In Progress” to “Completed” Click the icon under, View Report to view the test results   The report will complete successfully or show completed with errors. The report will show where the error is located, what the error is, and what action(s) to take for resolution. Remember, if you need to work with Oracle Support to resolve your issue, attach the report to your Service Request so the engineer can start working the issue. Completed with errors Completed successfully with no errors If you have questions, please ask in the E-Business Suite Category’s Diagnostic Tools Community. You may find the answer waiting for you in a prior community discussion or in one of the resources posted by an Oracle Support moderator. Oracle’s Period Close Diagnostic, and the other E-Business Suite Diagnostics, save you time and help keep you on schedule. If you run the Period Close Diagnostic throughout the month, you can identify issues to resolve and get help, if needed. When opening a Service Request, attaching the output from the diagnostic report, speeds resolution. With the issues resolved ahead of time, your Period Close should complete without errors. Avoiding the unexpected, helps to close your books on time and without late nights or working through your weekend. Recommended Reads E-Business Suite Diagnostics Period / Year End Close [ID 402237.1] lists all of the Closing Period Diagnostic Tests. I highly recommend that customers execute these tests prior to closing a period. The period closing tests listed in this document help you identify known issues that prevent a successful period close. Use these tests prior to closing a period. To learn about all the available EBS Diagnostics, please review the E-Business Suite Diagnostics Overview [ID 342459.1].

  • creating the nodes for path finding during run time - more like path making and more

    - by bigbadbabybear
    i'm making my 1st game. i'm using javascript as i currently want to learn to make games without needing to learn another language but this is more of a general game dev question its a 2d turn-based tile/grid game. you can check it here http://www.patinterotest.tk/ it creates a movable area when you hover a player and it implements the A* algo for moving the player. The Problem: i want to make the 'dynamic movable area creation' already implement a limited number of steps for a player. The Questions: what is a good way to do this? is there another algorithm to use for this? the A* algorithm needs a start and destination, with what i want to do i don't have a destination or should i just limit the iteration of the A* algo to the steps variable? hopefully you understand the problem & questions easily

  • Is an 'if password == XXXXXXX' enough for minimum security?

    - by Morgan Herlocker
    If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

  • Why write clean, refactored code?

    - by Shamal Karunarathne
    Hi programming lovers, This is a question I've been asking myself for a long time. Thought of throwing out it to you. From my experience of working on several Java based projects, I've seen tons of codes which we call 'dirty'. The unconventional class/method/field naming, wrong way of handling of exceptions, unnecessarily heavy loops and recursion etc. But the code gives the intended results. Though I hate to see dirty code, it's time taking to clean them up and eventually comes the question of "is it worth? it's giving the desired results so what's the point of cleaning?" In team projects, should there be someone specifically to refactor and check for clean code? Or are there situations where the 'dirty' codes fail to give intended results or make the customers unhappy? Do feel free to comment and reply. And tell me if I'm missing something here. Thanks.

Cyber Monday is only a scant six years old, an invention of online retailers looking to create a shopping day to compete with the in-store frenzy of Black Friday. Although quite a few retailers offer online Black Friday deals, Cyber Monday is a the biggest day for online deals–many shoppers fail to find the things they were looking for on Black Friday and turn to online sources.

  • Why is Google Webmaster Tools crawling invalid URLS and showing 500 errors?

    - by Amos Kane
    Google Webmaster tools is reporting 12k+ 500 errors. Eeek! None of the URLS are valid- they all contain www.youtube.com. First, why is Google crawling these URLS if they don't exist? I supplied a sitemap, and they are of course not in the sitemap. I don't have a robots.txt blocking anything. I've checked for invalid redirects--none, and checked for unclosed tags or something that would throw www.youtube.com into the URL by accident--none. In every 'linked from', the referring URL is also a bad URL, with www.youtube.com in it. The Google Tools report no malware, and I can't check the server logs because the host won't give me access. Really stuck!! Any ideas appreciated!

  • Where to find a mentor?

    - by Fanatic23
    I have been looking around for resources that discuss about mentors, including questions in the stackexchange network. I see that the general response has been to join open source projects and/or check out local user groups if there exists any. Are we sure that joining open source project can get me a mentor? It can grab eyeballs, yes, if the project is exciting enough but a mentor? I am not so sure. What do you guys think? Finally, I'd want my mentor to be in a specific domain as opposed to just being a coding wizard and that makes the search even more difficult. Suggestions?
