  • Please explain this Rails method to me like I'm a little kid.

    - by Senthil
    I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I see he is saving the user ip, user agent and referrer, but am confused with the req=(request) line. Any help is appreciated. Thanks

  • Why do I get this error when trying to set up a class variable

    - by Jennifer
    I'm new to PHP so maybe I am overlooking something here but the following: class someClass { var $id = $_GET['id']; function sayHello() { echo "Hello"; } } gives the following error: Parse error: syntax error, unexpected T_VARIABLE in C:\xampp\htdocs\files\classes.php on line 13 If instead of $_GET['id'] I set the variable $id to a string, everything is fine though.

  • Ctrl-M chars when transfer files SFTP

    - by eve
    Hi, I am sending files from a windows system to a Unix SFTP server using JSCAPE ftp client. However, I am experiencing the following issue: When uploading a text file from windows to UNiX, each line of text files transferred contains Control-M characters. I did some search and found out that If I use the "ASCII" transfer mode it should solve the issue. But the Ctrl-M is still appearing on the files. Can anyone throw some light in this issue? thanks in advance

    - by roddik
    Hello. I have a Java app that takes pretty much time to be initialized (so I can't use command-line like interface) and I need to pass text and receive the output of a Java method from Python. Is it possible to load the Java application, have it opened all the time the Python script runs and use a method from that app?

  • Compressing an uncompressed MSI file

    - by Noam Gal
    We have a setup project that produces an uncompressed MSI file and no Setup.exe at all, to be later compressed by NSIS. In a special build setting, I want to copy that MSI before it's being wrapped by NSIS, change the copy, and keep it. I would also like to compress it, after it has been created by the msbuild. Is there a simple way (command line tool of some kind, maybe?) I can use to just compress an already created msi file?

    Let's say you're away from your computer and all you've got is a web browser. You'd still like to run a piece of code (e.g. to check an answer on SO). What are your options? Let's create a list of on-line interpreters of various programming languages. Here are some examples: Python: http://try-python.mired.org/ Haskell: http://tryhaskell.org/ Scala: http://www.simplyscala.com/ Many languages: http://ideone.com/ Many languages: http://codepad.org/

  • Suppressing a function's command window output in Matlab

    - by Ali
    A function I'm using has "display()" in it (or other things that display messages on command window), so it outputs a lot of things (x 1200) on command line when I run my code, which makes things hard to track and observe. Is there a way to suppress the output of this specific function? Ending the statement with semicolon obviously doesn't help.

  • Is it possible to convert text to shape in VML /canvas/SVG ?

    - by est
    Hello, I need to display a text in 3D using vml/canvas/svg and do some transformation to the shape of the text like the effect of Ctrl+T in photoshop, even align a line of text to a curve, is there a way to convert text to shape first? The only thing close is getImageData() in firefox which is not ideal but OK. Any better methods? Using browser-specific hacks or voodoo is OK, but no Flash please :)

  • SaveFileDialog problem (C#) (VS2008)

    - by typoknig
    Hi all, I am having an issue with SaveFileDialog for some reason. All I want to do is extract data from a text box line by line and write it to a text file, then save that text file to the desktop. The first bit of code works fine (though it doesn't save to the desktop). The second bit of code is what I want to use, but when it creates the text file the text file is empty. What did I do wrong in my second bit of code? This code works, but it does not save to the desktop and it isn't as nice as the second code. //When the Save button is clicked the contents of the text box will be written to a text file. private void saveButton_Click(object sender, EventArgs e) { int textBoxLines = textBox.Lines.Count(); if (File.Exists(saveFile)) { result = MessageBox.Show("The file " + saveFile + " already exists.\r\nDo you want to replace it?", "File Already Exists!", MessageBoxButtons.YesNo); if (result == DialogResult.Yes) { TextWriter tw1 = new StreamWriter(saveFile); for (int i = 0; i < textBoxLines; i++) { tw1.WriteLine(textBox.Lines.GetValue(i)); } tw1.Close(); } if (result == DialogResult.No) { MessageBox.Show("Please move or rename existing " + saveFile + "\r\nBefore attempting to save again.", "Message"); } } else { TextWriter tw2 = new StreamWriter(saveFile); for (int i = 0; i < textBoxLines; i++) { tw2.WriteLine(textBox.Lines.GetValue(i)); } tw2.Close(); } } This code does not work, but it is what I want to use. //When the Save button is clicked the contents of the text box will be written to a text file. private void saveButton_Click(object sender, EventArgs e) { int textBoxLines = textBox.Lines.Count(); Stream saveStream; SaveFileDialog saveDialog = new SaveFileDialog(); saveDialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"; saveDialog.FilterIndex = 2; saveDialog.RestoreDirectory = true; saveDialog.FileName = (saveFile); saveDialog.InitialDirectory = (Environment.GetFolderPath(Environment.SpecialFolder.Desktop)); if (saveDialog.ShowDialog() == DialogResult.OK) { if ((saveStream = saveDialog.OpenFile()) != null) { StreamWriter tw = new StreamWriter(saveStream); for (int i = 0; i < textBoxLines; i++) { tw.WriteLine(textBox.Lines.GetValue(i)); } saveStream.Close(); } } }

  • Seeing release markers in svn log

    - by chuanose
    Whenever we make a release of a project we'll create a tag to capture the snapshot. It will be very helpful to be able to see which revisions in the trunk history were used in certain releases. I know the TortoiseSVN revision graph shows this information, but I'm wondering if there's a way to see it in the command-line svn log? I'm coming from a Clearcase background where we'll be able to see the release labels in the history.
