  • Voting on Hacker News stories programmatically?

    - by igorgue
    I decided to write an app like: http://michaelgrinich.com/hackernews/ but for Android devices, my idea will use a web application backend (because I rather code in Python and for the web than completely in Java for Android devices). What I have right now implemented is something like this: $ curl -i http://localhost:8080/stories.json?page=1\&stories=1 HTTP/1.0 200 OK Date: Sun, 25 Apr 2010 07:59:37 GMT Server: WSGIServer/0.1 Python/2.6.5 Content-Length: 296 Content-Type: application/json [{"title": "Don\u2019t talk to aliens, warns Stephen Hawking", "url": "http://www.timesonline.co.uk/tol/news/science/space/article7107207.ece?", "unix_time": 1272175177, "comments": 15, "score": 38, "user": "chaostheory", "position": 1, "human_time": "Sun Apr 25 01:59:37 2010", "id": "1292241"}] The next step (and final I think) is voting, my design is doing something like this: $ curl -i http://localhost:8080/stories/1?vote=up -u username:password Will vote up and: $ curl -i http://localhost:8080/stories/1?vote=down -u username:password Down. I have no idea how to do it though... I was planning to use Twill but the login link is always different, e.g.: http://news.ycombinator.com/x?fnid=7u89ccHKln Later the Android app will consume this API. Any experience with programmatically browsing Hacker News?

  • How to show jQuery is working/waiting/loading ?

    - by Kim
    How do I show a loading picture and/or message to the user ? If possible, would I like to know how to make it full screen with grey-dimmed background. Kinda like when viewing the large picture from some galleries (sorry, no example link). Currently do I add a CSS class which has the image and other formating, but its not working for some reason. Results from the search do get inserted into the div. HTML <div id="searchresults"></div> CSS div.loading { background-image: url('../img/loading.gif'); background-position: center; width: 80px; height: 80px; } JS $(document).ready(function(){ $('#searchform').submit(function(){ $('#searchresults').addClass('loading'); $.post('search.php', $('#'+this.id).serialize(),function(result){ $('#searchresults').html(result); }); $('#searchresults').removeClass('loading'); return false; }); });

  • How do I search for a string with quotes?

    - by every_answer_gets_a_point
    I am searching for the string <!--m--><li class="g w0"><h3 class=r><a href=" within the HTML source of this link: http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=Santarus+Inc? this is how I am searching for it: string html_string = "http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=" + biocompany; html = new WebClient().DownloadString(html_string); d=html.IndexOf(@"<!--m--><li class=""g w0""><h3 class=r><a href=""",1); For some reason it is finding an occurrence of it at position 45 (in other words d=45) but this incorrect.

  • CSS column height different on Opera/IE to FF

    - by Infiniti Fizz
    Hi all, Thanks to everyone who helped with my last question but I've got a new browser-independent problem: For some reason, the image navigator (not yet functioning) on a website I'm working on is currently not displaying in the correct place on Firefox. It appears in the right place in IE8 and Opera but Firefox seems to have a problem with it. As can be seen in the below image, the imageContainer div (the image and the left/right arrows) appears on top of the footer, this is how it should look i.e. how it looks in IE8 and Opera. But in the image below, the imageContainer div is cutting into the footer div for some reason, and I don't know why. imageContainer has a margin-top: 110px; to get it in the right place at the bottom of its column. There are 2 columns, the left housing the paragraphs and imageContainer and the right housing the Calendar and contact details. The footer div also has clear: both; Also, it's not just the image that is falling into the footer, it's the arrows as well only they are the same colour as the footer so this isn't immediately apparent. Any ideas why it isn't displaying correctly? Is there a better way of aligning the imageContainer to the bottom of it's column (to keep the box shape of the website) other than using the margin-top to position it? Thanks in advance, infinitifizz

  • C# Process Binary File, Multi-Thread Processing

    - by washtik
    I have the following code that processes a binary file. I want to split the processing workload by using threads and assigning each line of the binary file to threads in the ThreadPool. Processing time for each line is only small but when dealing with files that might contain hundreds of lines, it makes sense to split the workload. My question is regarding the BinaryReader and thread safety. First of all, is what I am doing below acceptable. I have a feeling it would be better to pass only the binary for each line to the PROCESS_Binary_Return_lineData method. Please note the code below is conceptual. I looking for a but of guidance on this as my knowledge of multi-threading is in its infancy. Perhaps there is a better way to achieve the same result, i.e. split processing of each binary line. var dic = new Dictionary<DateTime, Data>(); var resetEvent = new ManualResetEvent(false); using (var b = new BinaryReader(File.Open(Constants.dataFile, FileMode.Open, FileAccess.Read, FileShare.Read))) { var lByte = b.BaseStream.Length; var toProcess = 0; while (lByte >= DATALENGTH) { b.BaseStream.Position = lByte; lByte = lByte - AB_DATALENGTH; ThreadPool.QueueUserWorkItem(delegate { Interlocked.Increment(ref toProcess); var lineData = PROCESS_Binary_Return_lineData(b); lock(dic) { if (!dic.ContainsKey(lineData.DateTime)) { dic.Add(lineData.DateTime, lineData); } } if (Interlocked.Decrement(ref toProcess) == 0) resetEvent.Set(); }, null); } } resetEvent.WaitOne();

  • CSS3 animations - how to make different animations to different elements on scroll

    - by DeanDeey
    I have a question about the doing CSS3 animations on scroll.. I found a code, that shows the DIV element after the user scrolls down: <script type="text/javascript"> $(document).ready(function() { /* Every time the window is scrolled ... */ $(window).scroll( function(){ /* Check the location of each desired element */ $('.hideme').each( function(i){ var bottom_of_object = $(this).position().top + $(this).outerHeight(); var bottom_of_window = $(window).scrollTop() + $(window).height(); /* If the object is completely visible in the window, fade it it */ if( bottom_of_window > bottom_of_object ){ $(this).animate({'opacity':'1'},500); } }); }); }); </script> I'm building a site, which one will have about 5 different boxes, which one will be shown when the user scrolls down to each box. But my question is, how i make the animation inside those boxes. Foe example: in each box there is title, content and images. How do i make all the elements appear after each other, because with this code all the class elements are shown at once. But i would like that if user scrolls down, first the tittle appears, then the content and at the end the images. And then when user scrolls to the next box, the same process repeat's itself. I use some CSS3 delays, but in this case i don't know how long will user take to scroll down. thanks!

  • iOS MapKit: Selected MKAnnotation coordinates.

    - by Oh Danny Boy
    Using the code at the following tutorial, http://www.zenbrains.com/blog/en/2010/05/detectar-cuando-se-selecciona-una-anotacion-mkannotation-en-mapa-mkmapview/, I was able to add an observer to each MKAnnotation and receive a notification of selected/deselected states. I am attempting to add a UIView on top of the selection annotation to display relevant information about the location. This information cannot be conveyed in the 2 lines allowed (Title/Subtitle) for the pin's callout. - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { Annotation *a = (Annotation *)object; // Alternatively attempted using: //Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; NSString *action = (NSString *)context; if ([action isEqualToString:ANNOTATION_SELECTED_DESELECTED]) { BOOL annotationSelected = [[change valueForKey:@"new"] boolValue]; if (annotationSelected) { // Actions when annotation selected CGPoint origin = a.frame.origin; NSLog(@"origin (%f, %f) ", origin.x, origin.y); // Test UIView *v = [[UIView alloc] init]; [v setBackgroundColor:[UIColor orangeColor]]; [v setFrame:CGRectMake(origin.x, origin.y , 300, 300)]; [self.view addSubview:v]; [v release]; }else { // Accions when annotation deselected } } } Results using Annotation *a = (Annotation *)object origin (154373.000000, 197135.000000) origin (154394.000000, 197152.000000) origin (154445.000000, 197011.000000) Results using Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; origin (0.000000, 0.000000) origin (0.000000, 0.000000) origin (0.000000, 0.000000) The numbers are large. They are not relative to the view (1024 x 768). I believe they are relative to the entire map. How would I be able to detect the exact coordinates relative to the entire view so that I can appropriately position my view?

  • Handle row deletion in UITableViewController

    - by Kamchatka
    Hello, I hava a UINavigationController. The first level is a UITableViewController, the second level just shows details on one of the items of the table view. In this detail view, I can delete the item. It deletes the underlying managed object. When I pop back to the view, I have a crash. I understand why, it's because I didn't update the cached array that contains the data. I looked at several tutorials and I don't exactly understand how am I supposed to handle deletion. Maybe I don't understand exactly where I should fetch the objects in the model. Should I do a query for every cellForRowAtIndexPath and take the item in the result at position indexPath.row? It doesn't look efficient. Should I check for changes somewhere and recache the whole query in an array. I would think CoreData would provide something more natural but I couldn't find it so far. Thanks in advance.

  • How-to display a .gif as background image?

    - by Vito De Tullio
    Hi! I have a javascript "loading" function like this: function splashScreen() { var div = document.createElement('div'); div.appendChild(document.createTextNode("some text")); div.setAttribute("style", "position: fixed; " + "width: 100%; height: 100%; " + "left: 0; top: 0; " + "z-index: 1000; " + "background: #fff url('img/loading.gif') no-repeat center; " + "font-size: x-large; " + "text-align: center; " + "line-height: 3em; " + "opacity: 0.75; " + "filter: alpha(opacity=75); "); document.getElementsByTagName('body')[0].appendChild(div); return true; } I use this function in the form action (onsubmit="return splashScreen()") to show a "rotating logo" while the next page load... The problem is in that "img/loading.gif" and safari (on winXP): in ff and ie I have no problems, and I clearly see the animated gif. In safari I can't see it. If I change the image with a (obviously static) png the image appears... Am I doing something wrong? What's the problem with safari?

  • How to shrink the ASPX page

    - by salvationishere
    I am developing a C#/ASP.NET web application in VS 2008. Currently this page is too tall. The buttons appear on top and then there is a large gap between these buttons and the resultLabel text. The following code is from my ASPX file. I have tried switching to the Design tab of this file and manually moving this label, but there is still a large gap. I'm sure this is simple. How do I correct this? Text="Now select from the dropdownlists which table columns from my database you want to map these fields to"     <table align="center"><tr> <td style="text-align: center;width: 300px;"> <asp:Label ID="resultLabel" runat="server" style="position:absolute; text-align:center; top:148px; left: 155px;" Visible="False"></asp:Label> </td></tr></table> <p>

  • How to apply CSS theme to only a specific jQuery-UI element?

    - by Thierry-Dimitri Roy
    I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

  • Risking the exception anti-pattern.. with some modifications

    - by Sridhar Iyer
    Lets say that I have a library which runs 24x7 on certain machines. Even if the code is rock solid, a hardware fault can sooner or later trigger an exception. I would like to have some sort of failsafe in position for events like this. One approach would be to write wrapper functions that encapsulate each api a: returnCode=DEFAULT; try { returnCode=libraryAPI1(); } catch(...) { returnCode=BAD; } return returnCode; The caller of the library then restarts the whole thread, reinitializes the module if the returnCode is bad. Things CAN go horribly wrong. E.g. if the try block(or libraryAPI1()) had: func1(); char *x=malloc(1000); func2(); if func2() throws an exception, x will never be freed. On a similar vein, file corruption is a possible outcome. Could you please tell me what other things can possibly go wrong in this scenario?

Here is the code: final Spinner hubSpinner = (Spinner) findViewById(R.id.myspinner); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.colours, android.R.layout.simple_spinner_item); adapter .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); hubSpinner.setAdapter(adapter); // hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { //code Object ttestt = hubSpinner.getSelectedItem(); final String test2 = ttestt.toString(); Toast message1 = Toast.makeText(Textbox.this, test2, Toast.LENGTH_LONG); message1.show(); String songtoplay = test2; // Need songtoplay to be available in another 'Public Void' } public void onNothingSelected(AdapterView<?> parentView) { //Code } }); Basically, it gets the value from the Spinner 'hubSpinner' and displays it in a Toast. I then want it to return a value for string variable 'songtoplay' -or find a way to make it global or useable in another Public Void, (Which is will a button, -loading the song to be played) Please help me, Thanks alot. James

  • Where to post code for open source usage?

    - by Douglas
    I've been working for a few weeks now with the Google Maps API v3, and have done a good bit of development for the map I've been creating. Some of the things I've done have had to be done to add usability where there previously was not any, at least not that I could find online. Essentially, I made a list of what had to be done, searched all over the web for the ways to do what I needed, and found that some were not(at the time) possible(in the "grab an example off the web" sense). Thus, in my working on this map, I have created a number of very useful tools, which I would like to share with the development community. Is there anywhere I could use as a hub, apart from my portfolio ( http://dougglover.com ), to allow people to view and recycle my work? I know how hard it can be to need to do something, and be unable to find the solution elsewhere, and I don't think that if something has been done before, it should necessarily need to be written again and again. Hence open source code, right? Firstly, I was considering coming on here and asking a question, and then just answering it. Problem there is I assume that would just look like a big reputation grab. If not, please let me know and I'll go ahead and do that so people here can see it. Other suggestions appreciated. Some stuff I've made: A (new and improved) LatLng generator Works quicker, generates LatLng based on position of a draggable marker Allows searching for an address to place the marker on/near the desired location(much better than having to scroll to your location all the way from Siberia) Since it's a draggable marker, double-clicking zooms in, instead of creating a new LatLng marker like the one I was originally using The ability to create entirely custom "Smart Paths" Plot LatLng points on the map which connect to each other just like they do using the actual Google Maps Using Dijkstra's algorithm with Javascript, the routing is intelligent and always gives the shortest possible route, using the points provided Simple, easy to read multi-dimensional array system allows for easily adding new points to the grid Any suggestions, etc. appreciated.

  • CSS Multiple multi-column divs

    - by accelerate
    I have a bunch of items (text, image, mixed content, etc) that I want to display. The user can define what row and what column that item appears in. For example, in row 1, there could be two items/columns, both images. In row two, there could be three items / columns, one with an image, two others as pure text. Oh, and the user may specify the width of any particular column/image/item. I have a solution that uses multiple tables that works. In essence, each row is a new table. This works for the most part. I'm wondering if I can use just divs? Now my CSS foo is lacking, and I tried to copy examples from the web, and I haven't been able to get it working. Right now I have something like this: `[for each row] [for each column] [content] ` But everything is overlapping each other. I've also tried using "position: relative", but things look even more borked. So can divs actually be used for multiple rows and different number of columns?

  • WPF - How to stop an ItemsControl psuedo-grid's columns from dancing/jumping around during layout

    - by Drew Noakes
    Several other questions on SO have come to the same conclusion I have -- using an ItemsControl with a DataTemplate for each item constructed to position items such that they resemble a grid is much simpler (especially to format) than using a ListView. The code resembles: <StackPanel Grid.IsSharedSizeScope="True"> <!-- Header --> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" SharedSizeGroup="Column1" /> <ColumnDefinition Width="Auto" SharedSizeGroup="Column2" /> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Text="Column Header 1" /> <TextBlock Grid.Column="1" Text="Column Header 2" /> </Grid> <!-- Items --> <ItemsControl ItemsSource="{Binding Path=Values, Mode=OneWay}"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" SharedSizeGroup="Column1" /> <ColumnDefinition Width="Auto" SharedSizeGroup="Column2" /> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Text="{Binding ColumnProperty1}" /> <TextBlock Grid.Column="1" Text="{Binding ColumnProperty2}" /> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </StackPanel> The problem I'm seeing is that whenever I swap the object to which the ItemsSource is bound (it's an ObservableCollection that I replace the reference to, rather than clear and re-add), the entire 'grid' dances about for a few seconds. Presumably it is making a few layout passes to get all the Auto-width columns to match up. This is very distracting for my users and I'd like to get it sorted out. Has anyone else seen this?

  • C# class design - expose variables for reading but not setting

    - by James Brauman
    I have a a polygon class which stores a list of Microsoft.Xna.Framework.Vector2 as the vertices of the polygon. Once the polygon is created, I'd like other classes to be able to read the position of the vertices, but not change them. I am currently exposing the vertices through this field: /// <summary> /// Gets the vertices stored for this polygon. /// </summary> public List<Vector2> Vertices { get { return _vertices; } } List<Vector2> _vertices; However you can change any vertex using code like: Polygon1.Vertices[0] = new Vector2(0, 0); or Polygon1.Vertices[0].X = 0; How can I limit other classes to be able to only read the properties of these vertices, and not be able to set a new one to my List? The only thing I can think of is to pass a copy to classes that request it. Note that Vector2 is a struct that is part of the XNA framework and I cannot change it. Thanks.

  • Prevent comment form re-submission

    - by Rob
    I'm got a comment form for an article and i'd to prevent re-submission. I notice that Worpdress handles this very well (going back doesn't cause the browser to request a form re-submission), but I can't figure out how they do it, even though our methods are very similar. My Script User visits mydomain.com/article/1/article_title.html Fills in a form which posts to mydomain.com/addnewcomment/1.html I then do a 302 redirect back to mydomain.com/article/1/article_title.html Now if I press back from this position it doesn't request a redirect. However, if I go to another page e.g. mydomain.com/tag/1/my_tag.html and press back it does resubmit the form. Obviously I want to prevent this. What Wordpress does User visits mydomain.com/?p=1 Fills in a form which posts to mydomain.com/wp-comments-post.php This then does a 302 redirect back to mydomain.com/?p=1 Pressing back or visiting another page and pressing back doesn't cause a re-submission. I've had a look through the WP code but I can't see how they manage this. Obviously it's something i'd like to achieve. Does anyone have any thoughts on where I may be going wrong? (I'm only using Wordpress as an example to prove that it's possible, obviously i'm not trying to exactly duplicate WP, that would be pointless)

  • Date Picker Control Not Displaying Proper Date (Access 2003)

    - by JPM
    Hi everyone, I just have a quick question. I am maintaining an app for my summer co-op position, and a new requirement came down today where the user requested to have a date control added to a form to mark the date of when an employee is "laid off". This control is enabled/disabled by a toggle button, and has its control source bound to a field that I added in the database. All the functionality has been added and tested, but.... The issue I am having is that the date picker is on a tab control (the 2nd page) and I am having problems trying to get the control to display the date that is stored in the field I created. I know the control is storing any changes made using it, but since the user asked to move the control over to the 2nd tab (it was on the first), it just shows today's date, not the date entered using the control. To make things a little more strange, if I place the control anywhere except the tab control, it seems to be working fine. I've even placed a textbox on the tab and set its control source to the database field, and it displays just fine. What gives? And I have registered the .ocx with Access, and as I mentioned before, the actual database is storing the data. Just not displaying it. Any ideas as to what I am doing wrong?

  • What is the scope of TRANSACTION in Sql server

    - by Shantanu Gupta
    I was creating a stored procedure and i got stuck in the writing methodology of me and my collegue. I am using SQL Server 2005 I was writing Stored procedure like this BEGIN TRAN BEGIN TRY INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH And my collegue was writing it like the below one BEGIN TRY BEGIN TRAN INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH Here the only difference that you will find is the position of writing Begin TRAN. According to me the methodology of my collegue should not work when an exception occurs i.e. Rollback should not get executed because TRAN does'nt have scope. But when i tried to run both the code, both was working in the same way. I am confused to know how does TRANSACTION works. Is it scope free or what ?
