  • Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

    - by Jascha
    I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

  • Simplest possible table entry editing / addition / deletion web toolkit (for use with php)

    - by Dave
    Hi, i'm building a website in php and i have tables presented that i need to allow the user to: 1. add new entry (only one at a time, which should appear as a new modal overlay) 2. delete multiple selected entries from 3. edit an existing entry (only one at one time, in a view similar to 1.) 4. re-arrange entries up and down. One by one is fine. Multiple / Grouping rearrangements are not not needed what jquery / js / anything toolkit would be the SIMPLEST to work with? (of course, i should be able to work with it in php). I did try hacking away at: http://www.ericmmartin.com/projects/simplemodal/ but had a terrible time trying to get it to work on editing some existing data (had problem passing data to it).

  • Wifi and 3G same time

    - by Skolleus
    For my App I need Data from both, a local Network and the Internet. The local Network (Wifi) has no connection to the internet so I have to use the mobile connection (3G for Example). But whenever I connect to the local Network, 3G stopps. After asking the Samsung Service, there is no way to change that in the UI. But they couldn't tell me, if there is a programmable Interface for that. There is a mobile access point inside, so there is a way to connect a Wifi device to the Internet (which means that both, a wifi and a 3G connection is possible the same time in that way). But for my App the phone/tab has to connect to the existing Network and use the 3G for Internet. So this is my question here. Is there a way to connect to an existing Network and using 3G for Internet the same time?

  • Allowing threads from python after calling a blocking i/o code in a python extension generated using

    - by SS
    I have written a python extension wrapping an existing C++ library live555 (wrapping RTSP client interface to be specific) in SWIG. The extension works when it is operated in a single thread, but as soon as I call the event loop function of the library, python interpreter never gets the control back. So if I create a scheduled task using threading.Timer right before calling the event loop, that task never gets executed once event loop starts. To fix this issue, I added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros manually in the SWIG auto generated wrapper cxx file around every doEventLoop() function call. But now, I want to do the same (i.e. allow threads) when SWIG generates the code itself and not to change any code manually. Has anyone done something similar in SWIG? P.S. - I would also consider switching to any other framework (like SIP) to get this working. I selected SWIG over any other technology is because writing SWIG interface was really very easy and I just had to include the existing header files.

  • Different formats of OpenIDs

    - by mecablaze
    stackoverflow, I am experimenting with implementing OpenID in my existing site. I have looked at Plaxo's article on this very subject and I'm a mite confused about something. I am using this PHP OpenID library. I have some code running, and I am getting a unique OpenID back. From myopenid.com, I am getting an id that looks like https://mecablaze.myopenid.com/ But from Yahoo and Google, I am getting an ID that much more cryptic, e.g. https://www.google.com/accounts/o8/id?id=AItOawlbp1cxujdJWDnpx72xVROOw-5V_WzIDZA Are Google's and Yahoo's "gibberish" ids unique for every login user, i.e. is this the value that I use to tie in with existing user on my web app?

  • How to Compile Sample Code

    - by James L
    I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File-New-Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error. I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

  • What is the motivation behind "Use Extension Methods Sparingly?"

    - by Robert Harvey
    I find them a very natural way to extend existing classes, especially when you just need to "spot-weld" some functionality onto an existing class. Microsoft says, "In general, we recommend that you implement extension methods sparingly and only when you have to." And yet extension methods form the foundation of Linq; in fact, Linq was the reason extension methods were created. Are there specific design criteria where using extension methods are perferred over inheritance or composition? Under what criteria are they discouraged?

  • turning open source software into a consulting business ?

    - by sofreakinghigh
    just some general and specific questions about running a business which uses open source software and sells training, services, and other value added solutions utilizing the open source asset(s). 1) how much modification do you need to make to an existing open source software/framework to give a new brand ? open source (GPLv3) branding issues here.... for ex) Mambo and Joomla, i think they are pretty much same ? but they have different labels. 2) Is there a disadvantage of promoting open source software/framework/suite in hopes of selling value added services and solutions on top of the Open source asset ? 3) can Open source assets be marketing point for lowered Total Ownership Cost and transparency ? meaning, clients will not be using some mysterious, opaque proprietary asset ? 4) is competition fierce? cost of developing software is non existing because you are using an open source asset. barrier to entry is minimal ??

  • Algorithm for Source Control System?

    - by Michael Stum
    I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

  • Building a complete online payment gateway like Paypal

    - by John Stewart
    So this question isn't about integrating an existing payment gateway into my site. This is more of a architectural question. I want to build a system similar to Paypal. Now I understand that Paypal offers a lot of features under the roof and I can't implement all of them at once. I want to implement the core functionality of Paypal and other such services. So my question is (rather discussion is) around how would one go about building such a system. Some points to discuss: Handle payments through existing banks. I am guessing that I would need access to local bank protocols to get this. Allow users to securely store and process their payments How does Paypal handle the transactions? Thoughts?

  • ASP.NET - fast Segmented downoad of file through webservice

    - by H4mm3rHead
    Hi, Im doing this project where i need to download files through a webservice (images, videos). The download MUST go through an existing webservice. The existing webservice was made when there were no need to upload and download files but the project has changed and now we need to do It through a webservice. Right now I have implemented the download as a method that returns a byte[], I open a streamreader and resds the entire file into a byte[] and returns it to my method. This is working file on small files <~1Mb, above it takes too long time. I want to show some progress (e.g. when the user downlaods a 20Mb video) which i cannot do right now. And i want to make it download much faster (is a strategy to use multithreading and several threads that downloads a part of the file?). It is within a WPF application i need to do this. Any ideas on how to approach this?

  • Android P2P Multiplayer game (with a) XMPP/Google talk b) JXTA peerdroid c) other way)

    - by Kristof
    Hi, I am an android developer and I made some board games. Now i want to make some of my board games multiplayer. I don't want to create and host my own web service, so i thought about P2P. The first thing i found was the XMPP protocol, however it's not real P2P, but if i can use the existing google talk service, i'm ready to go. Is this possible while using your existing google account without interfering with the normal working of your google talk client? Then i heard about JXTA, a real P2P solution, and it's already ported from J2ME to Android (http://code.google.com/p/peerdroid/). Maybe i am overcomplexing things here (as i do sometimes) I just want to know the easiest way to do simple P2P for a boardgame. All your opinions are welcome! Thanks in advance

  • Scala class to implement two Java Interfaces - how?

    - by puudeli
    Hi, I have just started learning Scala and I'm now wondering how I could implement two different Java interfaces with one Scala class? Let's say I have the following interfaces written in Java public interface EventRecorder { public void abstract record(Event event); } public interface TransactionCapable { public void abstract commit(); } But a Scala class can extend only one class at a time. How can I have a Scala class that could fulfill both contracts? Do I have to map those interfaces into traits? Note, my Scala classes would be used from Java as I am trying to inject new functionality written in Scala into an existing Java application. And the existing framework expects that both interface contracts are fulfilled.

  • Selecting a radio button when a dropdown value changes

    - by Tim F.
    My setup is something like this: radiobutton1 - selection1 radiobutton2 - selection2 textinput1 I want radiobutton1 to be selected whenever selection1 is changed, and I want radiobutton2 to be selected whenever either selection2 or textinput1 is changed. There has to be a simple javascript solution here... I just can't find it. Here's my actual code ("$semopt" is a string holding the html code for the options on the first selection input): <input type='radio' name='semester' value='existing'/>Existing semester: <select name='sem_id'">$semopt </select><br/> <input type='radio' name='semester' value='new'/>New Semester: <select name='sem_name'"> <option value='Fall'>Fall</option> <option value='Spring'>Spring</option> </select> <input name='sem_year' value='$thisyear' size='5'"/><br/>

  • PL/SQL Package invalidated

    - by FrustratedWithFormsDesigner
    I have a script that makes use of a package (PKG_MY_PACKAGE). I will change some of the fields in a query in that package and then recompile it (I don't change or compile any other packages). I run the script and I get an error that looks like ORA-04068: existing state of packages has been discarded ORA-04061: existing state of package body "USER3.PKG_MY_PACKAGE" has been invalidated ORA-04065: not executed, altered or dropped package body "USER3.PKG_MY_PACKAGE" ORA-06508: PL/SQL: could not find program unit being called: "USER3.PKG_MY_PACKAGE" ORA-06512: at line 34 I run the script again (without changing anything else in the system) and the script executes successfully. I thought that when I compiled before I executed the script that would fix any invalid references. This is 100% reproducible, and the more I test this script the more annoying it gets. What could cause this, and what would fix it? (oracle 10g, using PL/SQL Developer 7)

  • Password reset by email without a database table

    - by jpatokal
    The normal flow for resetting a user's password by mail is this: Generate a random string and store it in a database table Email string to user User clicks on link containing string String is validated against database; if it matches, user's pw is reset However, maintaining a table and expiring old strings etc seems like a bit of an unnecessary hassle. Are there any obvious flaws in this alternative approach? Generate a MD5 hash of the user's existing password Email hash string to user User clicks on link containing string String is validated by hashing existing pw again; if it matches, user's pw is reset Note that the user's password is already stored in a hashed and salted form, and I'm just hashing it once more to get a unique but repeatable string. And yes, there is one obvious "flaw": the reset link thus generated will not expire until the user changes their password (clicks the link). I don't really see why this would be a problem though -- if the mailbox is compromised, the user is screwed anyway.

  • Gridview delete/edit not working when using select parameter

    - by Brian Carroll
    new to ASP.NET. I created a sqldatasource and set up basic select query (SELECT * FROM Accounts) using the wizard. I then had the sqldatasource wizard create the INSERT, EDIT and DELETE queries. Connected this datasource to a gridview with EDITING and DELETING enabled. Everything works fine. The SELECT query returns all records and I can edit/delete them. Now I need to send a parameter to the SELECT command to filter the records to those with the user's id (pulled from Membership.GetUser). When I add this parameter, the SELECT command works fine, but the EDIT/DELETE buttons in the gridview no longer work. No error is generated. The page refreshes but the records were not updated in the database. I don't understand what is wrong. CODE: <% Dim u As MembershipUser Dim userid As String u = Membership.GetUser(User.Identity.Name) userid = u.ProviderUserKey.ToString SqlDataSource1.SelectParameters("UserId").DefaultValue = userid %> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1"> <Columns> <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" /> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" /> <asp:BoundField DataField="UserId" HeaderText="UserId" SortExpression="UserId" /> <asp:BoundField DataField="AccountName" HeaderText="AccountName" SortExpression="AccountName" /> <asp:BoundField DataField="DateAdded" HeaderText="DateAdded" SortExpression="DateAdded" /> <asp:BoundField DataField="LastModified" HeaderText="LastModified" SortExpression="LastModified" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:CheckingConnectionString %>" DeleteCommand="DELETE FROM [Accounts] WHERE [ID] = @ID" InsertCommand="INSERT INTO [Accounts] ([UserId], [AccountName], [DateAdded], [LastModified]) VALUES (@UserId, @AccountName, @DateAdded, @LastModified)" SelectCommand="SELECT * FROM [Accounts] WHERE [UserId] = @UserId" UpdateCommand="UPDATE [Accounts] SET [UserId] = @UserId, [AccountName] = @AccountName, [DateAdded] = @DateAdded, [LastModified] = @LastModified WHERE [ID] = @ID"> <DeleteParameters> <asp:Parameter Name="ID" Type="Int32" /> </DeleteParameters> <InsertParameters> <asp:Parameter Name="UserId" Type="String" /> <asp:Parameter Name="AccountName" Type="String" /> <asp:Parameter Name="DateAdded" Type="DateTime" /> <asp:Parameter Name="LastModified" Type="DateTime" /> </InsertParameters> <UpdateParameters> <asp:Parameter Name="UserId" Type="String" /> <asp:Parameter Name="AccountName" Type="String" /> <asp:Parameter Name="DateAdded" Type="DateTime" /> <asp:Parameter Name="LastModified" Type="DateTime" /> <asp:Parameter Name="ID" Type="Int32" /> </UpdateParameters> <SelectParameters> <asp:Parameter Name="UserId"/> </SelectParameters> </asp:SqlDataSource>

  • ORM framework that extends base class with database-implementation.

    - by aioobe
    I have a game consisting of a client / server + a webpage. A central notion in both client and game-/webserver is an Account. Accounts are stored in a database thus I'm in need of some ORM and recently had a look at Hibernate and Cayenne. My understanding however, is that both frameworks provide an "DatabaseBackedAccount"-class which I extend with my other Account methods. My problem is that the Account class is reused heavily on the client side, and I would obviously not want to include database-related code on the client implementation. My current solution is to have an Account class (shared by server and client) and extend this with a DatabaseBackedAccount (overriding setter-methods and providing a commit method) on the server side. I find this quite natural and nice, however I've had to implement all gory sql-details and ORM myself. Is there any way to "turn the table" in any existing ORM framework, so that the generated classes extend my existing class?
