  • Silence output from SimpleXMLRPCServer

    - by Corey Goldberg
    I am running an xml-rpc server using SimpleXMLRPCServer from the stdlib. My code looks something like this: import SimpleXMLRPCServer import socket class RemoteStarter: def start(self): return 'foo' rs = RemoteStarter() host = socket.gethostbyaddr(socket.gethostname())[0] port = 9000 server = SimpleXMLRPCServer.SimpleXMLRPCServer((host, port)) server.register_instance(rs) server.serve_forever() every time the 'start' method gets called remotely, the server prints an access line like this: <server_name> - - [10/Mar/2010 13:06:20] "POST /RPC2 HTTP/1.0" 200 - I can't figure out a way to silence the output so it doesn't print these access lines to stdout. anyone?

  • Complex Django filter question

    - by HWM-Rocker
    Lets say I have this class (simplified): class Tag (...): children = models.ManyToManyField(null=True, symmetrical=False) Now I already implemented the functions get_parents, get_all_ancestors. Is there a nice pythonic way to just the top level tags? If I had designed my Tags differently (to point to the parents instead) I would just make get_all_parents().filter(children=null). My first thought is to create a new function that will go recursively through all parents and save those that has none. But is there a possibility with filters or Query-objects to do the same (with fewer lines of code)? Thanks for your help. [edit] When it is finished, it should be a hierarchical tagging system. Each tag can have children, parents, but only the children are saved. I want to get all the top level tags, that point through many children / childrens children to my tag.

  • Importing Python module from the Bash

    - by Morlock
    I am launching a Python script from the command line (Bash) under Linux. I need to open Python, import a module, and then have lines of code interpreted. The console must then remain in Python (not quit it). How do I do that? I have tried an alias like this one: alias program="cd /home/myname/programs/; python; import module; line_of_code" But this only starts python and the commands are not executed (no module import, no line of code treated). What is the proper way of doing this, provided I need to keep Python open (not quit it) after the script is executed? Many thanks.

  • Changing text size on a ggplot bump plot

    - by Tom Liptrot
    Hi, I'm fairly new to ggplot. I have made a bumpplot using code posted below. I got the code from someones blog - i've lost the link.... I want to be able to increase the size of the lables (here letters which care very small on the left and right of the plot) without affecting the width of the lines (this will only really make sense after you have run the code) I have tried changing the size paramater but that always alter the line width as well. Any suggestion appreciated. Tom require(ggplot2) df<-matrix(rnorm(520), 5, 10) #makes a random example colnames(df) <- letters[1:10] Price.Rank<-t(apply(df, 1, rank)) dfm<-melt(Price.Rank) names(dfm)<-c( "Date","Brand", "value") p <- ggplot(dfm, aes(factor(Date), value, group = Brand, colour = Brand, label = Brand)) p1 <- p + geom_line(aes(size=2.2, alpha=0.7)) + geom_text(data = subset(dfm, Date == 1), aes(x = Date , size =2.2, hjust = 1, vjust=0)) + geom_text(data = subset(dfm, Date == 5), aes(x = Date , size =2.2, hjust = 0, vjust=0))+ theme_bw() + opts(legend.position = "none", panel.border = theme_blank()) p1 + theme_bw() + opts(legend.position = "none", panel.border = theme_blank())

  • jQuery style Constructors in PHP

    - by McB
    Is there a way to instantiate a new PHP object in a similar manner to those in jQuery? I'm talking about assigning a variable number of arguments when creating the object. For example, I know I could do something like: ... //in my Class __contruct($name, $height, $eye_colour, $car, $password) { ... } $p1 = new person("bob", "5'9", "Blue", "toyota", "password"); But I'd like to set only some of them maybe. So something like: $p1 = new person({ name: "bob", eyes: "blue"}); Which is more along the lines of how it is done in jQuery and other frameworks. Is this built in to PHP? Is there a way to do it? Or a reason I should avoid it?

  • Is there a more efficient way to set variables on a RadioButton's CheckChanged event?

    - by C Patton
    I have 16 radio buttons in an application of mine.. I have to set a variable based on which one was selected.. and I've produced some very ugly code doing this.. private void Foo_CheckedChanged(object sender, EventArgs e) { convertSource = 1; } private void Bar_CheckedChanged(object sender, EventArgs e) { convertSource = 2; } private void Baz_RadioButton_CheckedChanged(object sender, EventArgs e) { convertSource = 3; } Now, I've been thinking about it and to be honest I thought there might have been a way to do it with a switch.. I just can't conceptualize it in my mind. If anyone could show me a more efficient way of doing this, I'd really appreciate it. It's just really bugging me that such a simple thing as this is taking up fifty to seventy lines of code. thanks, cpatton

  • Silverlight Line Graph with Gradient

    - by gav
    I have a series of points which I will turn into a line on a graph. What I want is to give the area under the graph a gradient fill. It would look somewhat similar to a Bloomberg graph like this; My question really has three parts; First, how should I fill only the area under the graph? Second, how do I fill that with a gradient? Finally, if I have multiple lines on the same graph any area under more than one line should have a greyscale gradient fill, how would you set this up? My biggest problem is deciding on the data structures to use, I could use many multiple sided shapes (One for each line/ data series) and then tell the brush to draw; Transparent if it's not in any shape The colour of one series if it's in one shape (Alpha relative to height to give grad) Black if it's in multiple shapes (Alpha relative to height to give grad) Then I'd draw the shapes' boundaries in white afterwards. Thanks, Gav

  • Formatting code in research reports

    - by RoseOfJericho
    I am currently writing a formal research report, and I'll be including JavaScript and PHP code. None of the sections of code will be more than 25 lines (so they're mere snippets). There will be approx. half a dozen snippets, each of which will have a couple of paragraphs explaining what is happening in the code and a discussion on its pros/cons. Is there an accepted way of displaying code in research reports? I'm thinking in terms of font, spacing, whether the code should be displayed inside the document or in an appendix, and related details. I have no contact with the body the report will be submitted to, and they have no published guidelines on how to format code.

  • I cant really wrap my head around BOOLEAN logic when I use NOT together with AND and OR

    - by Bq
    Im trying to understand how boolean logic works when I use NOT. To give an example using awk I have a text file containing CORE PORT CORE PORT COREPORT CORE COREPORT And I would like to remove all COREPORT lines. The way I thought I would do it was with (NOT CORE) AND (NOT PORT) eg awk '/!CORE/&&/!PORT/{print}' But when I try it out Im actually supposed to use OR instead of AND awk '/!CORE/||/!PORT/{print}' I would be really glad if some one could explain where my thinking is wrong and super glad if it could be visualized with a venn diagram or something like the boolean machine at kathyschrock

  • Customising event delegates in the jQuery validation plug-in

    - by Russell
    I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

  • Visualize compiler warnings

    - by christoffer
    I'm looking for a way to visualize compiler warnings and remarks, by annotating or otherwise showing which lines cause a report. This is much like a modern IDE like NetBeans or Eclipse already does, but I'd like to take output from several compilers (and other static code analysis tools) at once, and create one single annotation in order to get a better overview. The rationale is that we've seen some problems go completely undetected by, say, Visual Studio 2005, but accurately detected with a proprietary ARM compiler, and vice versa. Cross-referencing warnings could potentially locate problems better, but doing so completely manually is infeasible. Have you heard of such a tool? Could an open-source IDE like Eclipse be extended to use several compilers at once, or has it already been done?

  • Automating Visual Studio 2010 from a console app

    - by JoelFan
    I am trying to run the following code (which I got from here). The code just creates a new "Output" pane in Visual Studio and writes a few lines to it. Public Sub WriteToMyNewPane() Dim win As Window = _ DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput) Dim ow As OutputWindow = win.Object Dim owPane As OutputWindowPane Dim cnt As Integer = ow.OutputWindowPanes.Count owPane = ow.OutputWindowPanes.Add("My New Output Pane") owPane.Activate() owPane.OutputString("My text1" & vbCrLf) owPane.OutputString("My text2" & vbCrLf) owPane.OutputString("My text3" & vbCrLf) End Sub Instead of running it as a Macro, I want to run it as an independent console application that connects to a currently running instance of Visual Studio 2010. I'm having a hard time figuring out how to set the value of DTE. I think I may need to call GetActiveObject, but I'm not sure how. Any pointers?

  • How to create an exception folder in a django site?

    - by ninja123
    There are a few folders where I house my django site that I want to be rendered as it would on any other non-django site. Namely, forum (vbulletin) and cpanel. I currently run the site with fastcgi. My .htaccess looks like this: AddHandler application/x-httpd-php5 .htm AddHandler application/x-httpd-php5 .html AddHandler fastcgi-script .fcgi Options +FollowSymLinks RewriteEngine On RewriteBase / AddHandler application/x-httpd-php5 .htm RewriteCond %{REQUEST_URI} !(mysite.fcgi) RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L] What are lines I can add so www.mysite.com/forum can not be picked up by django url and be rendered as it would do normally. Thanks.

  • Prototypes Object.extend with multiple objects that contain there own functions.

    How would I achieve something along the lines of this.. var Persistence = new Lawnchair('name'); Object.extend(Lawnchair.prototype, { UserDefaults: { setup: function(callback) { // "save" is a native Lawnchair function that doesnt //work because // "this" does not reference "Lawnchair" // but if I am one level up it does. Say if I defined // a function called UserDefaults_setup() it would work // but UserDefaults.setup does not work. this.save({key: 'key', value: 'value'}); // What is this functions scope? // How do I access Lawnchairs "this" } }, Schedule: { refresh: function(callback) { } } }); //this get called but doesnt work.

  • Stretch column table in Primefaces

  • Which thread invokes SensorEventListener.onSensorChanged

    - by Christoph Heindl
    From my records it seems that SensorEventListener.onSensorChanged callback is called by the same thread that registered the callback. I.e there must be some message-queue synchronization going on in the background which allows the activitys UI-Thread to handle the callbacks. That leads to my question: Is there a need to synchronize SensorEventListener.onSensorChanged with the activitys UI-thread, assuming that the activitys UI-thread registered the SensorEventListener? I cannot find any documentation references, but can see various examples calling invalidate() unsychronized or synchronize the entire callback. I used something along the lines of Log.i(TAG, "" + Thread.currentThread().getId()); to retrieve threading information. I'm running android 2.1 update1. Best regards, Christoph

  • Emacs CEDET and system include paths

    - by synasius
    Hello everyone, I'd like to add path to the openMPI library headers. So, after i found all openMPI headers are in /usr/lib/openmpi/include/* i added these two lines to my .emacs: (semantic-add-system-include "/usr/lib/openmpi/include" 'c-mode) (semantic-add-system-include "/usr/lib/openmpi/include" 'c++-mode) I think this is ok, but it's not working! This is the result of semantic-c-describe-envirnoment command: This file's system include path is: /usr/include /usr/local/include/ /usr/lib/gcc/i486-linux-gnu/4.4.3/include/ /usr/lib/gcc/i486-linux-gnu/4.4.3/include-fixed/ /usr/include/ Can't figure out what's wrong or what i'm missing Thanks

  • Modifying a model and texture mid-game code

    - by MicroPirate
    Just have a question for anyone out there who knows some sort of game engine pretty well. What I am trying to implement is some sort of script or code that will allow me to make a custom game character and textures mid-game. A few examples would be along the lines of changing facial expressions and body part positions in the game SecondLife. I don't really need a particular language, feel free to use your favorite, I'm just really looking for an example on how to go about this. Also I was wondering if there is anyway to combine textures for optimization; for example if i wanted to add a tattoo to a character midgame, is there any code that could combine his body texture and the tattoo texture into one texture to use (this way I can simply just render one texture per body.) Any tips would be appreciated, sorry if the question is a wee bit to vauge.

  • Using Multiple Foreign Keys to the same table in LINQ

    - by Graeme
    I have a table Users and a table Items In the Items table, I have fields such as ModifiedBy CreatedBy AssignedTo which all have a userId integer. The database is set up to have these as foreign keys back to the Users table. When using LINQToSQL, the relationships which are automatically built from the dbml end up giving me names like User, User1 and User2 e.g. myItem.User1.Name or myItem.User2.Name Obviously this isn't very readable and I'd like it be along the lines of myItem.CreatedByUser.Name or myItem.ModifiedByUser.Name etc I could change the names of the relationships but that means I have to redo that every time I change the db schema and refresh the dbml. Is there any way round this?

  • Assigning a default value to a final variable in case of an exception in Java

    - by frenetisch applaudierend
    Why won't Java let me assign a value to a final variable in a catch block after setting the value in the try block, even if it is not possible for the final value to be written in case of an exception. Here is an example that demonstrates the problem: public class FooBar { private final int foo; private FooBar() { try { int x = bla(); foo = x; // In case of an exception this line is never reached } catch (Exception ex) { foo = 0; // But the compiler complains // that foo might have been initialized } } private int bla() { // You can use any of the lines below, neither works // throw new RuntimeException(); return 0; } } The problem is not hard to work around, but I would like to understand why the compiler does not accept this. Thanks in advance for any inputs!

  • Accurate Timings with Oscilloscopes on PC

    - by Paul Bullough
    In the world of embedded software (firmware) it is fairly common to observe the order of events, take timings and optimise a program by getting it to waggle PIO lines and capturing their behavior on an oscilloscope. In days gone by it was possible to toggle pins on the serial and parallel ports to achieve much the same thing on PC-based software. This made it possible to capture host PC-based software events and firmware events on the same trace and examine host software/firmware interactions. Now, my new laptop ... no serial or parallel ports! This is increasingly the case. So, does anyone have any suggestions as to go about emitting accurate timing signals off a "modern" PC? It strikes me that we don't have any immediately programmable, lag-free output pins left. The solution needs to run off a laptop, so using add-on cards that only plug into desktops are not permitted.

  • Move constructor and assignment operator: why no default for derived classes?

    - by doublep
    Why there is default move constructor or assignment operator not created for derived classes? To demonstrate what I mean; having this setup code: #include <utility> struct A { A () { } A (A&&) { throw 0; } A& operator= (A&&) { throw 0; } }; struct B : A { }; either of the following lines throws: A x (std::move (A ()); A x; x = A (); but neither of the following does: B x (std::move (B ()); B x; x = B (); In case it matters, I tested with GCC 4.4.

  • How can I add an Items-like property to my User Control?

    - by Dan Tao
    It's pretty straightforward to add simple properties to a User Control that will appear in the desired categories in the Windows Forms designer, e.g.: [Category("Appearance")] public Color BackColor { get { return _textBox.BackColor; } set { _textBox.BackColor = value; } } What if I want to expose a more complex property, such as a collection of items of a type I define? I'm thinking something along the lines of the ListView.Items property, or the DataGridView.Columns property -- where the user of the control can access this complex property via a more specialized pop-up form (as opposed to a simple TextBox or ComboBox). Even a simple nudge in the right direction would be much appreciated.

  • Using PIG with Hadoop, how do I regex match parts of text with an unknown number of groups?

    I'm using Amazon's elastic map reduce. I have log files that look something like this random text foo="1" more random text foo="2" more text noise foo="1" blah blah blah foo="1" blah blah foo="3" blah blah foo="4" ... How can I write a pig expression to pick out all the numbers in the 'foo' expressions? I prefer tuples that look something like this: (1,2) (1) (1,3,4) I've tried the following: TUPLES = foreach LINES generate FLATTEN(EXTRACT(line,'foo="([0-9]+)"')); But this yields only the first match in each line: (1) (1) (1)
