  • jQuery Autocomplete using extraParams to pass additional GET variables

    - by paperclip
    I am referring specifically to the jQuery Autocomplete v1.1 plugin by Jörn Zaefferer [source: http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/] as there seems to be quite a few variations of this plugin. I'm trying to pass additional parameters to the server when the user starts typing because I have multiple fields that I want autocomplete to provide suggestions for. In addition to the query, I want to send the input name attribute to the server but I can't seem to use $(this).attr('name') within the extraParams. My jQuery: $('.ajax-auto input').autocomplete('search.php', { extraParams: { search_type: function(){ return $(this).attr('name'); } } }) This is my HTML. <form method="post" action="#" id="update-form" autocomplete="off"> <ol> <li class="ajax-auto"> <label for="form-initials">Initials</label> <input type="text" id="form-initials" name="initials" /> </li> <li class="ajax-auto"> <label for="form-company">Company</label> <input type="text" id="form-company" name="company" /> </li> </ol> </form> Any suggestions?

  • Xceed DataGrid SelectedItem issue

    - by Patrick K
    In my project I have an Xceed data grid which is bound to a data source with many records and record details. I am attempting to create a context menu option that will allow the user to search for a specific detail in a specific column. While I have successfully completed the functionality there is a UI part that is giving me some trouble, in that when I select the row in C#, if that row is not in view the row is never focused on. Thus the user has to scroll up and down looking for the row with expanded details. I am able to set the SelectedRow and expand the details like so: this.grid.AutoFilterValues[userColumn].Clear(); this.grid.AutoFilterValues[userColumn].Add(userValue); if (this.creditLinesDataGridControl.Items.Count > 0) { this.grid.SelectedItem = this.grid.Items[0]; this.grid.ExpandDetails(this.grid.Items[0]); } else { MessageBox.Show("Value not found in column: " + userColumn); } this.grid.AutoFilterValues[userColumn].Clear(); where userColumn and userValue are set previously in the method. How can I make the grid focus on the row after I've set the SelectedItem and expanded the details? Thanks, Patrick

  • Help with CSS - getting an element to fill 100% of the remaining vertical space

    - by Jack W-H
    Hi folks I'd consider myself a reasonable standard CSS/XHTML chap but I'm pretty baffled by this. The problem is available here: http://furnace.howcode.com - (note that the site is still in development, most stuff doesn't work, and it's likely to change fairly quickly as it is updated often). Basically I've got a fluid layout that needs to work in the same proportions on any resolution. Here's a screenshot of how the designer invisioned it (I apologise for my Paint-tool anotations): I want the tabs and the search box to STAY at the top of Col2, whilst there should be a scrollable area beneath it where the results are returned. I want NO vertical viewport scrolling, only within the 100%-height area thingy. My problem is this. If you take a look at http://furnace.howcode.com, you'll see that I've got a bit of a problem. I've made a placeholder black-background div which I will turn into the Tabs shortly. However I want the Col2 div to float BENEATH this and fill 100% of the remaining vertical height (i.e. go to the bottom of the screen, nomatter what the resolution is) and Col3 to be in the place where Col2 currently has been put (it normally is there automatically, when Col2 is in the right place!). I hope that makes sense. If you need to me to clarify please just ask. Cheers! Jack

  • I/O error(socket error): [Errno 111] Connection refused

    - by Schitti
    I have a program that uses urllib to periodically fetch a url, and I see intermittent errors like : I/O error(socket error): [Errno 111] Connection refused. It works 90% of the time, but the othe r10% it fails. If retry the fetch immediately after it fails, it succeeds. I'm unable to figure out why this is so. I tried to see if any ports are available, and they are. Any debugging ideas? For additional info, the stack trace is: File "/usr/lib/python2.6/urllib.py", line 235, in retrieve fp = self.open(url, data) File "/usr/lib/python2.6/urllib.py", line 203, in open return getattr(self, name)(url) File "/usr/lib/python2.6/urllib.py", line 342, in open_http h.endheaders() File "/usr/lib/python2.6/httplib.py", line 868, in endheaders self._send_output() File "/usr/lib/python2.6/httplib.py", line 740, in _send_output self.send(msg) File "/usr/lib/python2.6/httplib.py", line 699, in send self.connect() File "/usr/lib/python2.6/httplib.py", line 683, in connect self.timeout) File "/usr/lib/python2.6/socket.py", line 512, in create_connection raise error, msg Edit - A google search isn't very helpful, what I got out of it is that the server I'm fetching from sometimes refuses connections, how can I verify its not a bug in my code and this is indeed the case?

  • jqGrid local data manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks edit I've solved this with the following code for the delete navGrid button }).navGrid('#pager', {add:true, del:true, refresh:false, search:false}, { ... }, ##edit parameters { ... }, ##add parameters {reloadAfterSubmit:false, clearAfterAdd:false, afterComplete: function () { ## clear and readd the row data so the row ids are sequential var savedData= $("#inputgrid").jqGrid('getRowData'); $("#inputgrid").jqGrid('clearGridData'); $("#inputgrid").jqGrid('addRowData', 'rn', savedData); } } ##delete parameters ); Basically just saving the grid data and then re-adding it so that the rowids are sequential again. For some reason it causes the row numbers down the left side to go start from 2 instead of one. Edit this was solved by using the latest jqGrid code in GitHub (27th April 2010)

  • Oracle & Active Directory : A love/hate relationship

    - by Frank
    Hi SO'ers, I'm currently trying to access Active Directory via the dbms_ldap API in Pl/Sql (Oracle). The trouble is that I'm not able to connect with my own username and password or anynoymously. However, in C# I can connect anonymously with this code : DirectoryEntry ldap = new DirectoryEntry("LDAP://Hostname"); DirectorySearcher searcher = new DirectorySearcher(ldap); searcher.Filter = "(SAMAccountName=username)"; SearchResult result = searcher.FindOne(); If I try to connect anonymously in Oracle, I only get the error(ORA-31202 : LDAP client/server error) when I try to search (and the result code for the bind is SUCCESS)... my_session := dbms_ldap.init('HOST','389'); retval := dbms_ldap.simple_bind_s(my_session, '', ''); retval := dbms_ldap.search_s(my_session, ldap_base, dbms_ldap.scope_subtree, 'objectclass=*', my_attrs, 0, my_message); Why is the anonymous connection is C# works but doesn't work in Pl/Sql? Do you have any other idea to connect to Active Directory via Oracle? Help me reunite them together. Thanks. Edit When I bind with anonymous credentials I get : ORA-31202: DBMS_LDAP: LDAP client/server error 00000000: LdapErr: DSID-0C090627, comment: In order to perform this operation a successful bind must be completed on the connection And if I try to connect with my credentials, which are supposed to be valid since I'm connected to the domain with it...

  • SQLite vs Firebird

    - by rwallace
    The scenario I'm looking at is "This program uses Postgres. Oh, you want to just use it single-user for the moment, and put off having to deal with installing a database server? Okay, in the meantime you can use it with the embedded single-user database." The question is then which embedded database is best. As I understand it, the two main contenders are SQLite and Firebird; so which is better? Criteria: Full SQL support, or as close as reasonably possible. Full text search. Easy to call from C# Locks, or allows you to lock, the database file to make sure nobody tries to run it multiuser and ends up six months down the road with intermittent data corruption in all their backups. Last but far from least, reliability. As I understand it, the disadvantages of SQLite are, No right outer join. Workaround: use left outer join instead. Not much integrity checking. Workaround: be really careful in the application code. No decimal numbers. Workaround: lots of aspirin. None of the above are showstoppers. Are there any others I'm missing? (I know it doesn't support some administrative and code-within-database SQL features, that aren't relevant for this kind of use case.) I don't know anything much about Firebird. What are its disadvantages?

  • Set focus on textbox in WPF from view model (C#) & wPF

    - by priyanka.sarkar
    I have a TextBox and a Button in my view. Now I am checking a condition upon button click and if the condition turns out to be false, displaying the message to the user, and then I have to set the cursor to the text box control. if (companyref == null) { Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation cs = new Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation(); MessageBox.Show("Company does not exist.", "Error", MessageBoxButton.OK, MessageBoxImage.Exclamation); cs.txtCompanyID.Focusable = true; System.Windows.Input.Keyboard.Focus(cs.txtCompanyID); } The above code is in the view model. The CompanyAssociation is the view name. But the cursor is not getting set in the TextBox. The xaml is as under <igEditors:XamTextEditor KeyDown="xamTextEditorAllowOnlyNumeric_KeyDown" Name="txtCompanyID" ValueChanged="txtCompanyID_ValueChanged" Text="{Binding Company.CompanyId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="{Binding ActualWidth, ElementName=border}" Grid.Column="1" Grid.Row="0" VerticalAlignment="Top" Margin="0,5,0,0" HorizontalAlignment="Stretch" IsEnabled="{Binding Path=IsEditable}" /> <Button Template="{StaticResource buttonTemp1}" Command="{Binding ContactCommand}" CommandParameter="searchCompany" Content="Search" Width="80" Grid.Column="2" Grid.Row="0" VerticalAlignment="Top" Margin="0" HorizontalAlignment="Left" IsEnabled="{Binding Path=IsEditable}" /> Please help

  • How to programmatically start a WPF application from a unit test?

    - by Lernkurve
    Problem VS2010 and TFS2010 support creating so-called Coded UI Tests. All the demos I have found, start with the WPF application already running in the background when the Coded UI Test begins or the EXE is started using the absolute path to it. I, however, would like to start my WPF application under test from the unit test code. That way it'll also work on the build server and on my peer's working copies. How do I accomplish that? My discoveries so far a) This post shows how to start a XAML window. But that's not what I want. I want to start the App.xaml because it contains XAML resources and there is application logic in the code behind file. b) The second screenshot on this post shows a line starting with ApplicationUnterTest calculatorWindow = ApplicationUnderTest.Launch(...); which is conceptually pretty much what I am looking for, except that again this example uses an absolute path the the executable file. c) A Google search for "Programmatically start WPF" didn't help either.

  • JSF invoke backing bean method and reRender components on ENTER key

    - by Markos Fragkakis
    Hi, I have a datatable with as search fields. I want a method on the backing bean to be invoked when ENTER key is pressed, as well as the DataTable to be re-rendered. My approach so far only works in IE 6, and 7, not in FF. This is the inputText: <h:inputText value="#{applicantProductListBean.applicantNameFilterValue}" id="applicantNameFilterValue" onkeypress="submitByEnter(event)"> </h:inputText> and this is the Javascript method I am invoking: function submitByEnter(e){ if(e.keyCode==13){ // alert("Enter was pressed"); e.returnValue=false; e.cancel=true; document.getElementById("applicantProductListForm:refreshButton").click(); } } As you can see, the Javascript method clicks on the button refresh, which exists on the page: <a4j:commandButton value="Refresh" id="refreshButton" action="#{applicantProductListBean.refreshData}" image="/images/icons/refresh48x48.gif" reRender="table, scroller"> </a4j:commandButton> The refreshData method does not return anything. As said before, this only works in IE 6 and IE 7. Does anyone know why it does not work in FF? An alternative I was considering was HotKey, which can indeed catch the event of ENTER, but it can only invoke Javascript, so it isn't appropriate. Is the proper way to do this via RichFaces or plain JSF? Cheers! UPDATE: Slightly modified the answer by BalusC, the script that works is: if (event.preventDefault) { // Firefox event.preventDefault(); } else { // IE event.returnValue = false; }

  • Matplotlib pick event order for overlapping artists

    - by Ajean
    I'm hitting a very strange issue with matplotlib pick events. I have two artists that are both pickable and are non-overlapping to begin with ("holes" and "pegs"). When I pick one of them, during the event handling I move the other one to where I just clicked (moving a "peg" into the "hole"). Then, without doing anything else, a pick event from the moved artist (the peg) is generated even though it wasn't there when the first event was generated. My only explanation for it is that somehow the event manager is still moving through artist layers when the event is processed, and therefore hits the second artist after it is moved under the cursor. So then my question is - how do pick events (or any events for that matter) iterate through overlapping artists on the canvas, and is there a way to control it? I think I would get my desired behavior if it moved from the top down always (rather than bottom up or randomly). I haven't been able to find sufficient enough documentation, and a lengthy search on SO has not revealed this exact issue. Below is a working example that illustrates the problem, with PathCollections from scatter as pegs and holes: import matplotlib.pyplot as plt import sys class peg_tester(): def __init__(self): self.fig = plt.figure(figsize=(3,1)) self.ax = self.fig.add_axes([0,0,1,1]) self.ax.set_xlim([-0.5,2.5]) self.ax.set_ylim([-0.25,0.25]) self.ax.text(-0.4, 0.15, 'One click on the hole, and I get 2 events not 1', fontsize=8) self.holes = self.ax.scatter([1], [0], color='black', picker=0) self.pegs = self.ax.scatter([0], [0], s=100, facecolor='#dd8800', edgecolor='black', picker=0) self.fig.canvas.mpl_connect('pick_event', self.handler) plt.show() def handler(self, event): if event.artist is self.holes: # If I get a hole event, then move a peg (to that hole) ... # but then I get a peg event also with no extra clicks! offs = self.pegs.get_offsets() offs[0,:] = [1,0] # Moves left peg to the middle self.pegs.set_offsets(offs) self.fig.canvas.draw() print 'picked a hole, moving left peg to center' elif event.artist is self.pegs: print 'picked a peg' sys.stdout.flush() # Necessary when in ipython qtconsole if __name__ == "__main__": pt = peg_tester() I have tried setting the zorder to make the pegs always above the holes, but that doesn't change how the pick events are generated, and particularly this funny phantom event.

  • UISearchBar delegate not called when used as UINavigationBar titleVIew?

    - by phooze
    I have a UITableViewController that I have specified as a UISearchBarDelegate. Up until now, I had programmatically added the UISearchBar to the headerView of the table, and there were no problems. I began to run out of screen real estate, so I decided to kill my normal UINavigationController title (which was text), and added the following code, moving my SearchBar from the table to the UINavigationBar: // (Called in viewDidLoad) // Programmatically make UISearchBar UISearchBar *tmpSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,45)]; tmpSearchBar.delegate = self; tmpSearchBar.showsCancelButton = YES; tmpSearchBar.autocorrectionType = UITextAutocorrectionTypeNo; tmpSearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone; [self set_searchBar:tmpSearchBar]; [tmpSearchBar release]; self.navigationItem.titleView = [self _searchBar]; This code works as expected - my UINavigationBar is now a UISearchBar. However, my delegate method: /** Only show the cancel button when the keyboard is displayed */ - (void) searchBarDidBeginEditing:(UISearchBar*) lclSearchBar { lclSearchBar.showsCancelButton = YES; } ...is no longer being called. I've breakpointed, and I've confirmed that the UISearchBar's delegate is indeed self, the view controller. Oddly, this delegate method is still called just fine: /** Run the search and resign the keyboard */ - (void) searchBarSearchButtonClicked:(UISearchBar *)lclSearchBar { _deepSearchRan = NO; [self runSearchForString:[[self _searchBar] text] isSlowSearch:NO]; [lclSearchBar resignFirstResponder]; } Any ideas why UINavigationBar is swallowing my delegate calls?? What am I missing?

  • which language to use for building web application?

    - by harshit
    Hi I already have experience in developing websites using java technologies ... Now i have a task to develop another website and i have the liberty to select technology to built. I dont want to built using Java/J2ee standard technology as i want to learn new language. The specification about website i can give is that: 1) its a real estate based site. 2) so it will have a db of real estate data around million records 3) website will have more than 1000 hits /day and will have various functionality like search, add , delete,generate reports etc. So i mean UI should be good and fast. Technologies i have in mind .NEt( i have already worked on it but it licensed so may not go for it) , Groovy, Ruby on rails ,Play, GWT etc ... I am a college student and the website is again of a student(non techie guy) so i have 5-6 mnths to bring the website up I have read about them but all have adv and disadv but would like to hear from people who have used it and can tell me what they felt about the languages and problems while developing it.. Please feel free to drop any opinion you feel . Thanks

  • Compare base class part of sub class instance to another base class instance

    - by Anders Abel
    I have number of DTO classes in a system. They are organized in an inheritance hierarchy. class Person { public int Id { get; set; } public string FirstName { get; set; } public string ListName { get; set; } } class PersonDetailed : Person { public string WorkPhone { get; set; } public string HomePhone { get; set; } public byte[] Image { get; set; } } The reason for splitting it up is to be able to get a list of people for e.g. search results, without having to drag the heavy image and phone numbers along. Then the full PersonDetail DTO is loaded when the details for one person is selected. The problem I have run into is comparing these when writing unit tests. Assume I have Person p1 = myService.GetAPerson(); PersonDetailed p2 = myService.GetAPersonDetailed(); // How do I compare the base class part of p2 to p1? Assert.AreEqual(p1, p2); The Assert above will fail, as p1 and p2 are different classes. Is it possible to somehow only compare the base class part of p2 to p1? Should I implement IEquatable<> on Person? Other suggestions?

    Hi, I am trying to use Ninject 2.0 with Asp .Net 3.5 web application. Following are the DLLS and it's versions I am using. Ninject.dll - v2.0.0.0 Ninject.Extensions.Logging.dll v2.0.0.0 Ninject.Web.dll v1.0.0.0 In my global.ascx.cs I have following method. protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(); kernel.Bind<IDataAccess>().To<DataAccessEntBlock>().InSingletonScope(); return kernel; } When I run the application I get following error. Error activating ILoggerFactory No matching bindings are available, and the type is not self-bindable. Activation path: 1) Request for ILoggerFactory Suggestions: 1) Ensure that you have defined a binding for ILoggerFactory. 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. 3) Ensure you have not accidentally created more than one kernel. 4) If you are using automatic module loading, ensure the search path and filters are correct. I am not understanding even though I am not trying to register Logger, it seems it is trying to create it's own. How can I resolve this error ? Do I have to use any of the Ninject's extension Logger ? Thanks GK

  • VERY strange stack overflow in C++ program

    - by mav
    Hello, I wrote a program some time ago (Mac OS X, C++, SDL, FMOD) and it perfomed rather good. But lately I wanted to extend its functionality and added some more code to it. And now, when I run it and try to test the new functionality, the program crashes with SIGABRT. Looking into debugger, on function stack I see: _kill kill$UNIX2003 raise __abort __stack_chk_fail odtworz <-- my function that was was modified As far as I know, "__stack_chk_fail" indicates a stack overflow. But that's not the weirdest thing about it. In this function "odtworz", I have some code like this: ... koniec = 0; while ( koniec == 0 ) { ... if (mode == 1) { ... } else if (mode == 2) { ... } else if (mode == 3) { ... } } mode is a global variable and is set to value "2" in a function before. And now imagine - if I delete the third if statement (mode == 3) which never gets executed in this mode, the program doesn't crash! Deleting code that doesn't even get to be executed helps the situation! Now, I don't want to delete this code because it's for other mode of my program. And it works fine there. So any hints where I can search? What could be possibly wrong with this?

  • What do you mean by the expressiveness in a programming language?

    - by prosseek
    I see a lot of the word 'expressiveness' when people want to stress one language is better than the other. But I don't see exactly what they mean by it. Is it the verboseness/succinctness? I mean, if one language can write down something shorter than the other, does that mean expressiveness? Please refer to my other question - http://stackoverflow.com/questions/2411772/article-about-code-density-as-a-measure-of-programming-language-power Is it the power of the language? Paul Graham says that one language is more powerful than the other language in a sense that one language can do that the other language can't do (for example, LISP can do something with macro that the other language can't do). Is it just something that makes life easier? Regular expression can be one of the examples. Is it a different way of solving the same problem: something like SQL to solve the search problem? What do you think about the expressiveness of a programming language? Can you show the expressiveness using some code? What's the relationship with the expressiveness and DSL? Do people come up with DSL to get the expressiveness?

  • Scrolling issues with GridView in Android

    - by Jared Thigpen
    I am having weird scrolling issues in my pretty simple GridView. Each item in the Grid is simply and ImageView and a TextView. The activity itself is simply an application selector. It looks like a rough version of the basic App Tray in Android. The issue is that after spending some times scrolling through my view, it will inevitably allow me to continue scrolling past the top row of icons, to a blank screen, and the scroll bar will disappear, leaving me stuck. It doesn't happen every time I go to the top of the view, only sometimes, and usually only after some excessive scrolling. If I happen to notice the problem and catch it before the top row disappears off the bottom of the screen, I can usually scroll back through the view and spot some icons missing. There are empty spaces in the grid, and I can only assume that those icons have been moved to some bizarre position, which is allowing the view to scroll past the top. This is my first Android app beyond a basic Hello World, so it's likely that I've just screwed up something in my layout files. I also realize that this is probably a pretty confusing description, so I'm hoping someone has experienced this and my search abilities simply were unable to find it. I can post my layout files or other code if someone thinks that's useful. Oh, and the program is built against 1.5, but is running on 2.2 (whatever state of 2.2 that was that snuck out last week) on my phone. I don't have enough apps to test this on an emulator, but could probably set something up if someone felt it necessary. Thanks in advance for any help on the issue.

  • Nesting gridview/formview in webuser control inside a parent gridview

    - by Stuart
    Hi, I'm developing an ASP.net 2 website for our HR department, where the front page has a matrix of all our departments against pay grades, with links in each cell to all the jobs for that department for that grade. These links take you a page with a gridview populated dynamically, as each department has a different number of teams, e.g. Finance has one team, IT has four. Each cell has a webuser control inserted into it. The user control has a sql datasource, pulling out all the job titles and the primary key, popuating a formview, with a linkbutton whose text value is bound to the job title. (I'm using a usercontrol as this page will also be used to show the results of a search of all roles in a range of grades for a department, and will have a varying number of rows). I've got everything to display nicely, but when I click on the linkbutton, instead of running the code I've put in the Click event, the page posts back without firing any events. Having looked around, it looks like I have to put an addhandler line in somewhere, but I'm not sure where, could anyone give me some pointers please? (fairly numpty please, I'm not too experience in ASP yet and am winging it. I'm also using VB but C# isn't a problem) This is how I'm inserting the controls into the parent grid, have I missed anything obvious? For row As Int16 = 0 To dgvRoleGrid.Rows.Count - 1 tempwuc = New UserControl tempwuc = LoadControl("wucRoleList.ascx") tempwuc.ID = "wucRoleList" & col.ToString tempwuc.EnableViewState = True dgvRoleGrid.Rows(row).Cells(col).Controls.Add(tempwuc) CType(dgvRoleGrid.Rows(row).FindControl(tempwuc.ID), wucRoleList).specialtyid = specid CType(dgvRoleGrid.Rows(row).FindControl(tempwuc.ID), wucRoleList).bandid = dgvRoleGrid.DataKeys(row)(0) CType(dgvRoleGrid.Rows(row).FindControl(tempwuc.ID), wucRoleList).familyid = Session("familyid") Next

  • Is there a perfect algorithm for chess?

    - by Overflown
    Dear Stack Overflow community, I was recently in a discussion with a non-coder person on the possibilities of chess computers. I'm not well versed in theory, but think I know enough. I argued that there could not exist a deterministic Turing machine that always won or stalemated at chess. I think that, even if you search the entire space of all combinations of player1/2 moves, the single move that the computer decides upon at each step is based on a heuristic. Being based on a heuristic, it does not necessarily beat ALL of the moves that the opponent could do. My friend thought, to the contrary, that a computer would always win or tie if it never made a "mistake" move (however do you define that?). However, being a programmer who has taken CS, I know that even your good choices - given a wise opponent - can force you to make "mistake" moves in the end. Even if you know everything, your next move is greedy in matching a heuristic. Most chess computers try to match a possible end game to the game in progress, which is essentially a dynamic programming traceback. Again, the endgame in question is avoidable though. -- thanks, Allan Edit: Hmm... looks like I ruffled some feathers here. That's good. Thinking about it again, it seems like there is no theoretical problem with solving a finite game like chess. I would argue that chess is a bit more complicated than checkers in that a win is not necessarily by numerical exhaustion of pieces, but by a mate. My original assertion is probably wrong, but then again I think I've pointed out something that is not yet satisfactorily proven (formally). I guess my thought experiment was that whenever a branch in the tree is taken, then the algorithm (or memorized paths) must find a path to a mate (without getting mated) for any possible branch on the opponent moves. After the discussion, I will buy that given more memory than we can possibly dream of, all these paths could be found.

  • Static IP for dynamic IP

    - by scape279
    I have a dynamic IP address. I would like to have a static IP, but Virgin Media don't allow static IPs for residential broadband services, even if you ask them really nicely and offer to pay for it without switching to a business tariff. I am already registered with a dynamic DNS service which is updated by my router eg me.example.com will always resolve to my dynamic IP. This is fine for some circumstances, but not if you can only enter an IP address into configuration files/hardware etc like firewalls, subversion services etc etc. Is there a way I can have a static IP address 'forwarding' to my dynamic IP? Would a possible solution involve tunnelling? Setting up a private proxy? Please note the following: I am able to buy an IP address from my web host. I have access to a webserver and I am able to create custom DNS zones. I'm happy to have a webserver running at home if necessary also. I do not wish to change broadband providers. I have zero control over the services that require the IP address entering so I cannot tackle the problem that way round (services I need to access are at work). PS I've tried googling this issue, but it is very difficult to search for as most results are related to dynamic dns (which I already have set up and isnt quite what I'm after)

  • Trouble using ‘this.files’ in GruntJS Tasks

    - by whomba
    Background: So I’m new to writing grunt tasks, so hopefully this isn’t a stupid question. Purpose of my grunt task: Given a file (html / jsp / php / etc) search all the link / script tags, compare the href / src to a key, and replace with the contents of the file. Proposed task configuration: myTask:{ index:{ files:{src:"test/testcode/index.html", dest:"test/testcode/index.html"}, css:[ { file: "/css/some/css/file.css", fileToReplace:"/target/css/file.css" }, { file: "/css/some/css/file2.css", fileToReplace:"/target/css/file2.css" } ], js:[ { file: "/css/some/css/file.css", fileToReplace:”/target/css/file.css" }, { file: "/css/some/css/file2.css", fileToReplace:"/target/css/file2.css" } ] } } Problem: Now, per my understanding, when dealing with files, you should reference the ‘this.files’ object because it handles a bunch of nice things for you, correct? Using intelliJ and the debugger, I see the following when i watch the ‘this.files’ object: http://i.imgur.com/Gj6iANo.png What I would expect to see is src and dest to be the same, not dest ===‘src’ and src === undefined. So, What is it that I am missing? Is there some documentation on ‘this.files’ I can read about? I’ve tried setting the files attribute in the target to a number of other formats per grunts spec, none seem to work (for this script, ideally the src / dest would be the same, so the user would just have to enter it once, but i’m not even getting in to that right now.) Thanks for the help

  • Need help understanding "TypeError: default __new__ takes no parameters" error in python

    - by Gordon Fontenot
    For some reason I am having trouble getting my head around __init__ and __new__. I have a bunch of code that runs fine from the terminal, but when I load it as a plugin for Google Quick Search Box, I get the error TypeError: default __new__ takes no parameters. I have been reading about the error, and it's kind of making my brain spin. As it stands I have 3 classes, with no sub-classes, each class has it's own defs. I never use def __init__ or def __new__, but I have gotten the distinct feeling that these are the functions (or the lack thereof) that would be giving me the error. I have no idea how to summarize the code down to a snippet that would be helpful here, since I'm a bit over my head, but the entire script can be found at github. Not expecting anyone to bugfix my code for me, I am just at my wit's end on this. A simple (plain english, not the quote from the python docs which I have read 20 times and still don't really understand) explination of why this error would pop up, or why I should be, or not be, using the __init__ and/or __new__ functions would be seriously appreciated. Thanks for any help you can give in advance.
