  • Intersection of two querysets in django

    - by unagimiyagi
    Hello, I can't do an AND on two querysets. As in, q1 & q2. I get the empty set and I do not know why. I have tested this with the simplest cases. I am using django 1.1.1 I have basically objects like this: item1 name="Joe" color = "blue" item2 name="Jim" color = "blue" color = "white" item3 name="John" color = "red" color = "white" Is there something weird about having a many-to-many relationship or what am I missing? queryset1 = Item.objects.filter(color="blue") this gives (item1, item2) queryset2 = Item.objects.filter(color="white") this gives (item2, item3) queryset1 & queryset2 gives me the empty set [] The OR operator works fine (I'm using "|" ) Why is this so?

  • Peak decomposition

    - by midtiby
    Hi I want to examine a NMR spectre and make the best fit of a specific peak using a sum of gaussians. With the following code it is possible to fit two gaussians to the peak, but can it easily be generalized to n gaussians? freq <- seq(100, 200, 0.1) signal <- 3.5*exp(-(freq-130)^2/50) + 0.2 + 1.5*exp(-(freq-120)^2/10) simsignal <- rpois(length(signal), 100*signal) + rnorm(length(signal)) plot(freq, simsignal) res <- nls(simsignal ~ bg + h1 * exp(-((freq - m1)/s1)^2) + h2 * exp(-((freq - m2)/s2)^2), start=c(bg = 4, h1 = 300, m1 = 128, s1 = 6, h2 = 200, m2 = 122, s2 = 4), trace=T) lines(freq, predict(res, freq), col='red') Another wish is a visulization of the contribution from each of the gaussians to the original peak, eg. the gaussians should be plotted side by side (instead of plotting their sum as done above).

  • VS 2010 Class Diagram Error "The type cannot be edited..."

    - by Eric J.
    A few of the classes on a VS 2010 class diagram are displayed with a red title. The Class Details window shows all of the methods, properties, fields and correctly shows no events. However, there's an entry under each of methods, properties, fields and events that states where the name should be: "The type cannot be edited because the source code file contains an error." However, the source file builds with no errors or warnings. Anyone seen this? Any idea how to fix it?

  • .NET Remoting Client's Problem when running on the machine with Multi NICs

    - by cui chun
    I built a .NET Remoting Client which works quite fine on the machine of single NIC, and lots of testing messages received via remoting event. But when additional NIC was added, the Client seemed to be able to connect the remoting Server, but the testing messages cannot arrive anymore. From debugging, the server end did trigger the event but the client didn't get that. Checking from google and find that a similar problem report: http://www.eggheadcafe.com/community/aspnet/2/10061570/reply.aspx I just wonder if any solutions? Thanks in advance!

  • hg access control to central repository

    - by andreas buykx
    We come from a subversion background where we have a QA manager who gives commit rights to the central repository once he has verified that all QC activities have been done. Me and a couple of colleagues are starting to use mercurial, and we want to have a shared repository that would contain our QC-ed changes. Each of the developers hg clones the repository and pushes his changes back to the shared repository. I've read the HG init tutorial and skimmed through the red bean book, but could not find how to control who is allowed to push changes to the shared repository. How would our existing model of QA-manager controlled commits translate to a mercurial 'central' repository?

  • Give me a practical use-case of Multi-set

    - by Calm Storm
    I would like to know a few practical use-cases (if they are not related/tied to any programming language it will be better).I can associate Sets, Lists and Maps to practical use cases. For example if you wanted a glossary of a book where terms that you want are listed alphabetically and a location/page number is the value, you would use the collection TreeMap(OrderedMap which is a Map) Somehow, I can't associate MultiSets with any "practical" usecase. Does someone know of any uses? http://en.wikipedia.org/wiki/Multiset does not tell me enough :) PS: If you guys think this should be community-wiki'ed it is okay. The only reason I did not do it was "There is a clear objective way to answer this question".

  • What do you use for recurring payments in a Rails Application?

    - by Chance
    I'm fairly new to rails so I'm definitely not up to speed on the community's best practices, tools, etc. So I figure this may be the best place to ask. What do you use for recurring billing in a rails app? From what I can tell, there are a number of options including rolling my own with ActiveMerchant or using one of the SaaS out there. As far as the SaaS recurring billing systems, I've only stumbled upon one thus far (chedder getter) and I'm hoping there are alternatives (if, for nothing else, so I can compare). Additionally, I've seen a few invoice systems but they either do not handle the payment portion, do not seem to fit well with the intention, or are extremely outdated. Thanks in advance!

  • how to feed a file to telnet

    - by knittl
    hello community, understanding http and headers i played around with telnet to send requests. to not type everything again and again and again i thought i'd write a small textfile with all the commands i need. my file is as simple as follows: GET /somefile.php HTTP/1.1 Host: localhost i then try to feed it to telnet with io-redirection: $ telnet localhost 80 < telnet.txt but all output i get is Trying ::1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. what am i doing wrong?

  • Performance optimization strategies of last resort?

    - by jerryjvl
    There are plenty of performance questions on this site already, but it occurs to me that almost all are very problem-specific and fairly narrow. And almost all repeat the advice to avoid premature optimization. Let's assume: the code already is working correctly the algorithms chosen are already optimal for the circumstances of the problem the code has been measured, and the offending routines have been isolated all attempts to optimize will also be measured to ensure they do not make matters worse What I am looking for here is strategies and tricks to squeeze out up to the last few percent in a critical algorithm when there is nothing else left to do but whatever it takes. Ideally, try to make answers language agnostic, and indicate any down-sides to the suggested strategies where applicable. I'll add a reply with my own initial suggestions, and look forward to whatever else the SO community can think of.

  • How does Bitmap.Save(Stream, ImageFormat) format the data?

    - by Matt Jacobsen
    I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

  • How can I check that the NSPasteboard is updated?

    - by Ben Packard
    I'm automating a copy command to place some text on the pasteboard every second or so - unfortunately this is my only way of accessing the text, which is in another application. After copying, I access the pasteboard text and process it. Sometimes, the copy command will be sent when nothing is selected - for example in textEdit, if the cursor is at the end of a line (instead of highlighting some text) and you hit copy, you get a system beep because there is nothing selected to copy. The pasteboard does not update and retains its previous data. I can't think of a creative way to identify when this happens. If I send a copy command and the pasteboard doesn't update, is there any kind of time stamp on the pasteboard I can access that will confirm that something has or hasn't been captured? I was looking at the changeCount, but I'm not sure what that is for exactly, and the documentation didn't help me much - red herring? Any simple and effective ideas gratefully received!

  • Will being self-taught limit me?

    - by Isaiah
    I'm 21 and am pretty efficient in html/css, python, and javascript. I also know my way around lisp languages and enjoy programing in them. My problem is that I'm extremely self-taught and not quite confident that I could land a job programing, but I really need a job soon as I've just become a father. I haven't even created a resume yet because I'm not really sure what to put on it except my lone experience. So I wanted to ask, will being primarily self-taught with some experience on small projects I've done for a few clients limit me too much? I mean I know I need some kind of education so I've enrolled part time in a community college to work on a degree in computer science, but it's years till then. And if it will limit me a lot, what kind of skills would be good to work on to make my chances any better? Thank You

  • Speech.Recognition GrammarBuilder/Choices Tree Structure

    - by user2210179
    In playing around with C#'s Speech Recognition, I've stumbled across a road block in the creation of an effective GrammerBuilder with Choices (more specifically, Choices of Choices). IE considering the following logical commands. One solution would to "hard code" every combination of Speech lines and add them to a GrammarBuilder (ie "SET LEFT COLOR RED" and "SET RIGHT CLEAR", however, this would quickly max out the limit of 1024, especially when dealing with number combinations. Another solution would to Append all 'columns' as "Choices" (and filter out incorrect paths upon 'recognition', however this seems like it's processor heavy and unnecessary. The middle ground, seems like the best path - with Choices of Choices - like a tree structure on a GrammarBuilder - however I'm not sure how to proceed. Any suggestions?

  • Attaching events in JavaScript

    - by R0MANARMY
    As comment to one of the questions here a commenter wrote (emphasis mine): ... By using an inline "onclick" you are doing a similar thing, but it is harder to maintain and more prone to issues. The JavaScript community as a whole has been moving away from inline JavaScript for a while now. This was referring to attaching events to HTML elements using $("#someID").click(function(){ do something here...; }); rather than <a id="someID" onclick="someFunction();"> Has there really been a shift away from the old school way of declaring events inline, and if so, what are the benefits of one of the other?

  • What unix text editor should I learn? [closed]

    - by sixtyfootersdude
    Maybe this should be a community wiki page... What unix text editor should I learn? My co-workers mostly use vi. I am thinking about vim because the syntax highlighting seems appealing. Is there any advantage to vi over vim? I know that there are a lot of emacs fans out there too? Is there any reason to learn a specific editor? Can you point me to some good learning references (for your suggested editor)? Thanks!

  • Why are my RSpec specs running twice?

    - by James A. Rosen
    I have the following RSpec (1.3.0) task defined in my Rakefile: require 'spec/rake/spectask' Spec::Rake::SpecTask.new(:spec) do |spec| spec.libs << 'lib' << 'spec' spec.spec_files = FileList['spec/**/*_spec.rb'] end I have the following in spec/spec_helper.rb: require 'rubygems' require 'spec' require 'spec/autorun' require 'rack/test' require 'webmock/rspec' include Rack::Test::Methods include WebMock require 'omniauth/core' I have a single spec declared in spec/foo/foo_spec.rb: require File.dirname(__FILE__) + '/../spec_helper' describe Foo do describe '#bar' do it 'be bar-like' do Foo.new.bar.should == 'bar' end end end When I run rake spec, the single example runs twice. I can check it by making the example fail, giving me two red "F"s. One thing I thought was that adding spec to the SpecTask's libs was causing them to be double-defined, but removing that doesn't seem to have any effect.

  • Collaborative localization website supporting Android strings.xml?

    - by Nicolas Raoul
    My open source Android application has internationalization done the Android way, with strings.xml files. The community has many people from many countries, and they are willing to contribute/improve translations using a collaborative website. There is Launchpad but it only supports the gettext format so we would have to use scripts, not very convenient. There is Crowdin but somehow this website seems dead, nearly no projects, and the download links do not work. Actually we started using Crowdin but all download links fail to give any strings.xml file back, see here. What website is convenient for translating open source Android applications?

  • Php PEAR, Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a special-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: 1.) Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? 2.) Can PEAR interface with the MySqli prepared statements I currently use? 3.) Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) 4.) Will it slow down my site once I have a significantly large member base?

  • Qt: Printing pageRect and paperRect issues

    I have following printing code: void Print(QPrinter *printer) { QPainter q(printer); q.setRenderHint(QPainter::HighQualityAntialiasing, true); q.setPen(QPen(QColor("red"))); q.drawRect(printer->pageRect()); q.drawLine(printer->pageRect().topRight(), printer->pageRect().bottomLeft()); q.setPen(QPen(QColor("blue"))); q.drawRect(printer->paperRect()); q.drawLine(printer->paperRect().topRight(), printer->paperRect().bottomLeft()); } The result is different with QPrintPreviewDialog, rendered PDF, output to printers (HP LaserJet, PdfFactory, PdfCreator). Most of time the resulting rectangle is out of paper. What to do so the output is similar to all printers?

  • Initialize window code Mac OS X

    - by Jarle
    I'm currently reading "the red book" for learning OpenGL properly, and in one of the first examples, the author writes a line that says "InitializeAWindowPlease();" as a place holder for the code that will make a window to draw the OpenGL content in. Since I'm using Xcode for my programing, I know that I "get" a window to work with automatically (and that I have to make my own OpenGL view in interfacebuilder). How can I make this with pure code? I'm trying to learn programming, and I'm not to happy about taking "shortcuts" all the time. How can I make a window to draw my openGL stuff in? With Objective-C and C code I would love to see it. My goal is that I can make it without opening interface builder at all:)

  • Is it possible to put binary image data into html markup and then get the image displayed as usual i

    - by Joern Akkermann
    It's an important security issue and I'm sure this should be possible. A simple example: You run a community portal. Users are registered and upload their pictures. Your application gives security rules whenever a picture is allowed to be displayed. For example users must be friends on each sides by the system, in order that you can view someone else's uploaded pictures. Here comes the problem: it is possible that someone crawls the image directories of your server. But you want to protect your users from such attacks. If it's possible to put the binary data of an image directly into the HTML markup, you can restrict the user access of your image dirs the user and group your web application runs of and pass the image data to your Apache user and group directly in the HTML. The only possible weakness then is the password of the user that your web app runs as. Is there already a possibility?

  • What things on a job listing should be avoided?

    - by Earlz
    Hello, I'm looking at trying my hand at a bit of freelancing. And looking at some of the listings, I can tell some of them are definitely, obviously wrong. "A web application mimicking youtube. Project must be completed in 2 weeks. Flat payment of $200. If you are not willing to do things this fast paced then do not apply" But some of them are more subtle and they give me a red flag inside, but I'm not sure to avoid them. What are some things in job listings to avoid for freelance programming jobs? What is the reason for avoiding that?

  • Metadata requirements for developers

    - by Paul James
    I'm tasked with providing a list of metadata requirements our data warehouse developers might need. This is not the business metadata (nice descriptions etc), but rather data required for change management (also known as impact assesment), data lineage etc. I've seen this article Meta Meta Data Data - Ralph Kimball but as I'm not the first person to do this I'm throwing it to the SO community. The actual question is this: What metadata do datawarehouse developers require to design, develop and manage change in ETL routines? PS: I'm trying to keep the answer platform agnostic but for context this is an Oracle database with PL/SQL and Datastage.
