• python how to find the median of a list

  - by user3450574

  I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))

• Open source web cam conference software

  - by BasicallyBoredWithoutAnOffice

  Quick question, has anyone ever come across either a web cam API or an open source alternative that can be easily integrated to a site without having any Flash or ActionScript experience. I should probably say what I'm trying to do.... The idea is to create a Facebook app that lets friends communicate (and meet new people too) in real time over web cam. However I don't have the required experience to write the Flash part so any help would be appreciated.

Complete the definition def constrainedMatchPair(firstMatch,secondMatch,length):

• Disable a button on click

  - by Hitz

  I have a button control. Once the user clicks on it, the click event should fire and then the button should get disabled. How can I do this? I have the option to use JQuery or JavasSript or both. Here is my button declaration: <asp:Button ID="Button1" runat="server" Text="Click Me" onclick="Button1_Click" /> On the button click code behind, I have added a Response.Write(). That should get executed and then the button should be disabled

• Resize form objects in Java

  - by PeerFull

  I have a Java applet, which is a form that draw shapes into it (Rect, Oval, Line). Each shape is represented by 2 points and can draw itself to the form. When the JApplet form resizes, I need to resize the shapes also while keeping the aspect ratio. I didn't find an high quality solution for doing this that solves this problem. Tried to write a solution from this, but it came up as lousy when tested, Can someone publish an example code for doing that please?

• How do I list all the files for a commit in git

  - by Philip Fourie

  I need to write a script that retrieves all files that were committed for a given SHA1. I have difficulty getting a nice formatted list of all files that were part of the commit. I have tried: git show a303aa90779efdd2f6b9d90693e2cbbbe4613c1d Although listing the files it also includes additional diff information that I don't need. I am hoping there is a simple git command that will provide such a list without me having to parse it from the above command.

• mvc create my own html helper, how can i access httpcontext?

  - by rj

  Hi, I've come across two recommendations for creating custom html helpers: either extend an existing one, or write your own class. I'd prefer to keep my custom code separated, it seems a bit sloppy to extend helpers for a decent-size application. But the benefit I see in extending is that 'This HtmlHelper helper' is passed as a parameter, through which I can get ViewContext.HtmlContext. My question is, how can I roll my own helper class and still have ViewContext.HtmlContext available to me? Thanks!

• Fast response on first Socket I/O request but slow every other time when communicating with remote serial port

  - by GreenGodot

  I'm using sockets to pass Serial commands to a remote device. And the response to that request is sent back and printed out. However, I am having a problem in that the first time it is instant but the rest of the time it can take up to 20 seconds to receive a reply. I think the problem is with my attempt at threading but I am not entirely sure. new Thread() { @Override public void run() { System.out.println("opened"); try { isSocketRetrieving.setText("Opening Socket"); socket = new Socket(getAddress(), getRemotePort())); DataOutput = new DataOutputStream(socket .getOutputStream()); inFromServer = new BufferedReader( new InputStreamReader(socket .getInputStream())); String line = ""; isSocketRetrieving.setText("Reading Stream......"); while ((line = inFromServer.readLine()) != null) { System.out.println(line); if (line.contains(getHandshakeRequest())) { DataOutput.write((getHandshakeResponse()toString() + "\r").getBytes()); DataOutput.flush(); DataOutput .write((getCommand().toString() + "\r").getBytes()); DataOutput.flush(); int pause = (line.length()*8*1000)/getBaud(); sleep(pause); } else if (line.contains(readingObject .getExpected())) { System.out.println(line); textArea.append("value = " + line + "\n"); textAreaScroll.revalidate(); System.out.println("Got Value"); break; } } System.out.println("Ended"); try { inFromServer.close(); DataOutput.close(); socket.close(); isSocketRetrieving.setText("Socket is inactive..."); rs232Table.addMouseListener(listener); interrupt(); join(); } catch (IOException e) { e.printStackTrace(); } catch (InterruptedException e) { System.out.println("Thread exited"); } } catch (NumberFormatException e1) { e1.printStackTrace(); } catch (UnknownHostException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }.start();

• .bat file to update loopback controller to external ip

  - by cable729

  Okay, so I've figured out how to get my external ip using wget: wget -q -O - http://whatismyip.com/automation/n09230945.asp that outputs the ip to the command console. adding currentip.txt to the end will write it to a text file. But what I want to do is use netsh interface ip set address name="Local Area Connection 2" source=static addr=[WHAT DO I PUT HERE] Also, a way to make the command prompt not flash would be nice too :)

• Ant: Create directory containing file if it doesn't already exist?

  - by Benny

  Basically, I get a path like "C:\test\subfolder1\subfolder2\subfolder3\myfile.txt", but it's possible that subfolders 1-3 don't exist already, which means I'd get an exception if I try to write to the file. Is there a way to create the directory structure the target file is in, either by using some task that creates the structure when it outputs to the file and then deleting the file, or by parsing the directory part of the path and using the mkdir task first? Any help is appreciated. Thanks, B.J.

• Writing " to a file in bash.

  - by S1syphus

  Simply I need to write "echo" t${count} = "$"t${count}" To a text file, including all the So the output would be something like: echo " t1 = $t1" With " as they are. So I have tried: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}" do echo "echo" t${count} = "$"t${count}"" (( count++ )) done >> long1.txt And variations on this such as: echo "echo" """"" t${count} = "$"t${count}"" But I guess the wrapping in double " is only for variables. Ideas?
