  • How to handle the browsers who don't support HTML5/CSS3

    - by Sheikh Aman
    Hi, I have been looking into HTML5 and CSS3 and have been liking it quite a lot. Got around the modernizr API, but am stuck at one point, and that leads to further confusions: How will I write a code that caters to the situation of non-compatibility between browsers ? This leads to the following confusions: if I write the doctype as <!DOCTYPE HTML> and my page is accessed in IE6, then ho IE6 will handle the page? If I try to include <video> tag and the page is again accessed by IE6/IE7IE8 (which don't support this tag), Then how am I supposed to be rolling back to flash for them? Should I use some JS to show/hide the content appropriately? I would love to hear some thoughts of you guys. If needed, please mark this post as a community wiki. Thanks!

  • OptionParser python module - multiple entries of same variable?

    - by jduncan
    I'm writing a little python script to get stats from several servers or a single server, and I'm using OptionParser to parse the command line input. #!/usr/bin/python import sys from optparse import OptionParser ... parser.add_option("-s", "--server", dest="server", metavar="SERVER", type="string", help="server(s) to gather stats [default: localhost]") ... my GOAL is to be able to do something like #test.py -s server1 -s server2 and it would append both of those values within the options.server object in some way so that I could iterate through them, whether they have 1 value or 10. Any thoughts / help is appreciated. Thanks.

  • Seeking through a streamed MP3 file with HTML5 <audio> tag

    - by Kyle Slattery
    Hopefully someone can help me out with this. I'm playing around with a node.js server that streams audio to a client, and I want to create an HTML5 player. Right now, I'm streaming the code from node using chunked encoding, and if you go directly to the URL, it works great. What I'd like to do is embed this using the HTML5 <audio> tag, like so: <audio src="http://server/stream?file=123"> where /stream is the endpoint for the node server to stream the MP3. The HTML5 player loads fine in Safari and Chrome, but it doesn't allow me to seek, and Safari even says it's a "Live Broadcast". In the headers of /stream, I include the file size and file type, and the response gets ended properly. Any thoughts on how I could get around this? I certainly could just send the whole file at once, but then the player would wait until the whole thing is downloaded--I'd rather stream it.

    - by Rees
    i'm trying to create a unordered list in Flex. My issue is that within each line, i want the word NEW to be a different font color and different font size from the rest of the label text.

  • Overtime culture slowly creeping in - How do I handle this?

    - by bobsmith123
    Our company was one of the very few companies that did not enforce overtime. As such, all my team members promptly worked 40-48 hours a week and everything was good. We hired a few new developers and one of them has positioned himself to be a team lead. He has started working overtime, sending emails in the middle of the night which has come somewhat as a shock for the laid back team. Obviously, the higher ups seem to love him for being the "bad guy" enforcing overtime. Before this goes out of control, what steps do I take to stop this from continuing. I would rather not bring this up with the bosses for the fear of being seen as a whining team member. I am not sure if I should reply to his email outside work hours and encourage him to enforce this culture on our team. Thoughts?

  • ODBC Linked server in sql 2005 doesn’t work from remote box

    - by mhj96813
    I have a dev workstation with sql 2005 installed and in it I created a linked server to a odbc connection to a clarion database. I can run select statements against it inside sql Mgt studio. When I take a second workstation and connect to the sql on the first box using sql mgt studio, then try the exact same query I get OLE DB provider "MSDASQL" for linked server "liveclarion" returned message "[SoftVelocity Inc.][TopSpeed ODBC Driver][ISAM]ISAM Table Not Found". Any thoughts? It appears to have the same functionality on a second sql server. No remote sql mgt studio connect success in queries against my linked ODBC clarion DB. All done with windows authentication and the same AD user.

  • How can I implement my own version of a MVC framework in ASP.NET?

    - by ace
    Hi - I would like to know how I can go about implementing my own version of a MVC framework in ASP.NET? I know there already is Microsoft provided ASP.NET MVC framework, but I want to learn MVC and thought the best way would be to implement my own flavor of a MVC framework on top of ASP.NET. Any thoughts / guidance ? Also, can anyone point me to a page where I can learn more about how microsoft implemented ASP.NET MVC ? I'm more interested in learning about the under the hood plumbing that goes on to implement the framework on top of asp.net, do they use HttpHandlers / HttpModules ? Thanks.

  • Umbraco -- controlling access to media by membership

    - by Ryan
    I need to set up access to media files with the following structure: A media folder is designated as belonging to a specific member group. Then, a sub-folder below that needs to be available to a subset of members from the parent's member group. Any thoughts on how this can best be accomplished? I'll render the actual file download links with a user control, but how should I set up this access control on the back end? I need a member-group picker and a multiple member picker. Do these exist anywhere?

  • Avoiding dispose of underlying stream

    - by danbystrom
    I'm attempting to mock some file operations. In the "real" object I have: StreamWriter createFile( string name ) { return new StreamWriter( Path.Combine( _outFolder, name ), false, Encoding.UTF8 ) ); } In the mock object I'd like to have: StreamWriter createFile( string name ) { var ms = new MemoryStream(); _files.Add( Path.Combine( _outFolder, name ), ms ); return new StreamWriter( ms, Encoding.UTF8 ) ); } where _files is a dictionary to store created files for later inspection. However, when the consumer closes the StreamWriter, it also disposes the MeamoryStream... :-( Any thoughts on how to pursue this?

  • compilation error: request member in something not a structure of union

    - by Fantastic Fourier
    Hi everybody, I'm having the above error request member rv in something not a structure of union. I've googled it and several answers told me it's when working with a pointer but tries to access it as a struct, where I should be using -> instead of . int foo(void * arg, struct message * msg) { struct fd_info * info = (struct something *) arg; int * socks[MAX_CONNECTION]; socks = &(info->_socks); // where int * _socks[MAX_CONNECTION] in struct info // do other things rv = sendto(socks[i], &msg, sizeof(&msg), NULL, &(csys->client_address), sizeof(csys->client_address)); ... } The problem is all of the arguments i have are pointers. i'm confused as to what is wrong. thanks to any comments/thoughts.

  • Visual Editor vs Manual code

    - by Albinoswordfish
    I'm not sure how it is using other frameworks but this questions is strictly regarding Java swing. Is it better to use a Visual Editor to place objects or to manually code the placement of the objects onto the frame (Layout managers or null layouts)? From my experience I've had a lot of trouble using Visual editors when it comes to different screen resolutions or changing the window size. Using manual code to place objects I've found that my GUIs behave a lot better with regard to the screen size issue. However when I want to change a small part of my GUI it takes a lot more work compared to using a visual editor Just wondering what people's thoughts were on this?

  • Python PyQT4 - Adding an unknown number of QComboBox widgets to QGridLayout

    - by ZZ
    Hi all, I want to retrieve a list of people's names from a queue and, for each person, place a checkbox with their name to a QGridLayout using the addWidget() function. I can successfully place the items in a QListView, but they just write over the top of each other rather than creating a new row. Does anyone have any thoughts on how I could fix this? self.chk_People = QtGui.QListView() items = self.jobQueue.getPeopleOffQueue() for item in items: QtGui.QCheckBox('%s' % item, self.chk_People) self.jobQueue.getPeopleOffQueue() would return something like ['Bob', 'Sally', 'Jimmy'] if that helps.

  • Best implementation for MySQL replication with Rails 3?

    - by vonconrad
    We're looking at potentially setting up replication for our primary MySQL database, and while setting up the replication seems pretty straight-forward, the application implementation seems a bit murkier. My first idea would be to set up a master-slave configuration and RW-splitting, with all write queries (CREATE, INSERT, UPDATE) going to master, and all read queries (SELECT) going to slave. Having read up on it, it seems that there are essentially two options for how to implement this with our app: Using an independent middleware layer for all MySQL connections, such as MySQL proxy or DBSlayer. However, the former is in Alpha and the latter has limited documentation. Using a Ruby-based gem/plugin, such as Octopus to achieve RW-splitting in the framework. If we wanted to go with a master-slave setup, what you recommend moving forward? The other thought I've had was to use a master-master configuration, but am unsure about the implementation of such a setup. Thoughts?

  • Logs overwritten in CruiseCControl.NET when there is multiple MSBuild Tasks.

    - by James Poulose
    I have two MSBuild tasks in my CC.NET config. In the end of the execution, i can see two blocks of warnings/errors in the log and published email. But the problem is that the contents of both the blocks are the same and that is from the second MSBuild task!! In another way, the second MSBuild task overwrites the first log, and then creates another one for itself effectively creating two exactly identical block!!! Do anybody have any thoughts on this? I am happy to provide more information if you require about the environment and configuration. Thanks, James Poulose

  • .Net User Messaging System

    - by bechbd
    I am wondering if there is a framework out there for .NET to help me with sending messages to users. I would love to be able to write all my messages to a single repository. I would then like to be able to send these messages out to a user based on preferences that they set. e.g. I would like to be able to send a Notification A out to user A via email and text message and send Notification B to user B via SMS and IM. Any thoughts on if something like this exists or would I need to write it?

  • MYSQL Convert rows to columns performance problem

    - by Tarski
    I am doing a query that converts rows to columns similar to this post but have encountered a performance problem. Here is the query:- SELECT Info.Customer, Answers.Answer, Answers.AnswerDescription, Details.Code1, Details.Code2, Details.Code3 FROM Info LEFT OUTER JOIN Answers ON Info.AnswerID = Answers.AnswerID LEFT OUTER JOIN (SELECT ReferenceNo, MAX(CASE DetailsIndicator WHEN 'cde1' THEN DetailsCode ELSE NULL END ) Code1, MAX(CASE DetailsIndicator WHEN 'cde2' THEN DetailsCode ELSE NULL END ) Code2, MAX(CASE DetailsIndicator WHEN 'cde3' THEN DetailsCode ELSE NULL END ) Code3 FROM DetailsData GROUP BY ReferenceNo) Details ON Info.ReferenceNo = Details.ReferenceNo There are less than 300 rows returned, but the Details table is about 180 thousand rows. The query takes 45 seconds to run and needs to take only a few seconds. When I type show processlist; into MYSQL it is hanging on "Sending Data". Any thoughts as to what the performance problem might be?

  • Why OpenGL ES texture mapping is very slow?

    - by Cinar
    I have an Android application that displays VGA (640x480) frames using OpenGL ES. The application reads each frame from a movie file and updates the texture accordingly. My problem is that, it is taking almost 30 ms. to draw each frame using OpenGL. Similar test using the Canvas/drawBitmap was around 6 ms on the same device. I'm following the same OpenGL calls that VLC Media Player is using, so I'm assuming that those are optimized for this purpose. I just wanted to hear your thoughts and ideas about it?

  • [BUG] Bus Error - What causes this in Ruby?

    - by viatropos
    I have run into this error 5 or 10 times over the past few years and have never found a clear answer to this problem. Here is the error: $ rake db:migrate /usr/lib/ruby/gems/1.8/gems/libxml-ruby-0.9.5/lib/libxml_ruby.bundle: [BUG] Bus Error ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0] Abort trap The app I am running this in is using RMagick. I have run into this problem when installing ImageMagick a while ago, and when installing Nokogiri, and when installing MySQL. For Nokogiri it was because I needed a more recent version of libxml. What are your thoughts on this? Any fixes? How can I check the version of RMagick the project is loading? I am on a Mac, 10.5.8. Thanks for the help, Lance

  • GameKit peer to peer wifi without wireless router?

    - by Tim
    Hi all! Thanks in advance for any thoughts about this. I'm looking for a way to do realtime inter-app communication in iOS via wi-fi (I need about 150 ft range and don't think bluetooth offers this) and wonder about the peer-to-peer connectivity offered by GameKit which, apparently offers both bluetooth and wi-fi connectivity. My question is: must participating devices be members of an available wireless network (via a wireless router) or is this connectivity truly peer-to-peer requiring no router? I understand Wi-fi Direct is coming and would likely be an option. Just wondering if I can do this utilizing services available in iOS today. Thanks! Tim

  • iOS CollectionView with horizontal paging instead of vertical scrolling

    - by Nico Griffioen
    I'm working on a project for a client. It's an iPad pdf reader. The client wants a collection view, but instead of scrolling vertically, he wants it to use a page control. It's pretty hard to explain, but what I basically want is all the PDFs on the device in a grid, like on the iBooks app. When that grid overflows, I want to use a page control to display the extra elements on a second page (like in the weather app). My thoughts on this were: - Create a page control with one page. - On that page, create a UICollectionView. - If the number of elements is greater than 9 add a page to the page control and add another UICollectionView, until there are enough pages to display all elements. However, this seems horribly inefficient, so my question is if there's a better way to do this.

  • NerdDinner difficulties

    - by George
    Hello guys, I'm having a problem with the Create method of the NerdDinner tutorial, which is very good BTW. As you can see here http://nerddinnerbook.s3.amazonaws.com/Part5.htm in the Create method, he removed the ID field of the aspx page. I did that too, but I cannot add any dinners because I get a primary key violation. How is NerdDinner controlling the ids of each dinner? I revised the tutorial and could not see any references to identity fields on SQL database. I even created a method to get me the highest id in the table: public int GetHighestDinnerId() { int resultado = (from dinner in dataContext.Dinners select dinner.DinnerId).Max(); return resultado; } which does not work either. Any thoughts? Thank you

  • Best practice. Do I save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

  • Help me understand Rails eager loading

    - by aaronrussell
    I'm a little confused as to the mechanics of eager loading in active record. Lets say a Book model has many Pages and I fetch a book using this query: @book = Book.find book_id, :include => :pages Now this where I'm confused. My understanding is that @book.pages is already loaded and won't execute another query. But suppose I want to find a specific page, what would I do? @book.pages.find page_id # OR... @book.pages.to_ary.find{|p| p.id == page_id} Am I right in thinking that the first example will execute another query, and therefore making the eager loading pointless, or is active record clever enough to know that it doesn't need to do another query? Also, my second question, is there an argument that in some cases eager loading is more intensive on the database and sometimes multiple small queries will be more efficient that a single large query? Thanks for your thoughts.

  • Why is sql server giving a conversion error when submitting date.today to a datetime column?

    - by kpierce8
    I am getting a conversion error every time I try to submit a date value to sql server. The column in sql server is a datetime and in vb I'm using Date.today to pass to my parameterized query. I keep getting a sql exception Conversion failed when converting datetime from character string. Here's the code Public Sub ResetOrder(ByVal connectionString As String) Dim strSQL As String Dim cn As New SqlConnection(connectionString) cn.Open() strSQL = "DELETE Tasks WHERE ProjID = @ProjectID" Dim cmd As New SqlCommand(strSQL, cn) cmd.Parameters.AddWithValue("ProjectID", 5) cmd.ExecuteNonQuery() strSQL = "INSERT INTO Tasks (ProjID, DueDate, TaskName) VALUES " & _ " (@ProjID, @TaskName, @DueDate)" Dim cmd2 As New SqlCommand(strSQL, cn) cmd2.CommandText = strSQL cmd2.Parameters.AddWithValue("ProjID", 5) cmd2.Parameters.AddWithValue("DueDate", Date.Today) cmd2.Parameters.AddWithValue("TaskName", "bob") cmd2.ExecuteNonQuery() cn.Close() DataGridView1.DataSource = ds.Projects DataGridView2.DataSource = ds.Tasks End Sub Any thoughts would be greatly appreciated.

  • What should be done first: Code reviews or Unit tests?

    - by goldenmean
    Hello, If a developer implements code for some module and wants to get it reviewed. What should be the order : *First unit test the module after designing test cases for the module, debugging and fixing the bugs and then give the modified code for peer code review (Pros- Code to be reviewed is 'clean' to a good extent. Reduces some avoidable review comments and rework. Cons- Developer might spend large time debugging/fixing a bug which could have pointed/anticipated in peer code reviews) Or *First do the code review with peers and then go for unit testing. What are your thoughts/experience on this? I believe this approach for unit testing, code reviewing should be programming language agnostic, but it would be interesting to know otherwise(if applicable) with specific examples. -AD
