  • Deploying Pylons with uWSGI

    - by Doug Farrell
    Hi all, We're trying to move our intranet to Pylons. My boss is trying to set up Pylons to use uWSGI behind Apache so he can set up multiple, independent applications. However, he's having a difficult time getting it set up, with some apparent code problems in the C source code for uWSGI. Does anyone have any suggestions for how to deploy Pylons applications that might help us out? Thanks, Doug

  • Best programming aids for a quadriplegic programmer

    - by Peter Rowell
    Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

  • How to write an XML file without header in Python?

    - by Nico
    Hi, when using Python's stock XML tools such as xml.dom.minidom for XML writing, a file would always start off like <?xml version="1.0"?> [...] While this is perfectly legal XML code, and it's even recommended to use the header, I'd like to get rid of it as one of the programs I'm working with has problems here. I can't seem to find the appropriate option in xml.dom.minidom, so I wondered if there are other packages which do allow to neglect the header. Cheers, Nico

  • JNLP desktop shortcut creation with Windows 7 : "cannot create shortcut"

    - by Touko
    Hi, we have an Java application deployed with Java Web Start (JNLP) that does a desktop shortcut. One client has issue with Windows 7 : in the end of startup/installation there is a message "cannot create shortcut". With our own Windows 7 machine we don't have problems and unfortunately we don't have much details yet. But if somebody has encountered similar issue or has some ideas to try, they are welcome =) Java version used at the client is 6u18. Br, Touko

  • Easy code-golf challenges

    - by chibineku
    I am interested in trying a few code-golf problems, but of a fairly easy level as I'm only a year old in terms of programming. Simple things, but that will make me think. I am comfortable in JavaScript and PHP at the moment.

  • Question About Example In Robert C Martin's _Clean Code_

    - by Jonah
    This is a question about the concept of a function doing only one thing. It won't make sense without some relevant passages for context, so I'll quote them here. They appear on pgs 37-38: To say this differently, we want to be able to read the program as though it were a set of TO paragraphs, each of which is describing the current level of abstraction and referencing subsequent TO paragraphs at the next level down. To include the setups and teardowns, we include setups, then we include the test page content, and then we include the teardowns. To include the setups, we include the suite setup if this is a suite, then we include the regular setup. It turns out to be very dif?cult for programmers to learn to follow this rule and write functions that stay at a single level of abstraction. But learning this trick is also very important. It is the key to keeping functions short and making sure they do “one thing.” Making the code read like a top-down set of TO paragraphs is an effective technique for keeping the abstraction level consistent. He then gives the following example of poor code: public Money calculatePay(Employee e) throws InvalidEmployeeType { switch (e.type) { case COMMISSIONED: return calculateCommissionedPay(e); case HOURLY: return calculateHourlyPay(e); case SALARIED: return calculateSalariedPay(e); default: throw new InvalidEmployeeType(e.type); } } and explains the problems with it as follows: There are several problems with this function. First, it’s large, and when new employee types are added, it will grow. Second, it very clearly does more than one thing. Third, it violates the Single Responsibility Principle7 (SRP) because there is more than one reason for it to change. Fourth, it violates the Open Closed Principle8 (OCP) because it must change whenever new types are added. Now my questions. To begin, it's clear to me how it violates the OCP, and it's clear to me that this alone makes it poor design. However, I am trying to understand each principle, and it's not clear to me how SRP applies. Specifically, the only reason I can imagine for this method to change is the addition of new employee types. There is only one "axis of change." If details of the calculation needed to change, this would only affect the submethods like "calculateHourlyPay()" Also, while in one sense it is obviously doing 3 things, those three things are all at the same level of abstraction, and can all be put into a TO paragraph no different from the example one: TO calculate pay for an employee, we calculate commissioned pay if the employee is commissioned, hourly pay if he is hourly, etc. So aside from its violation of the OCP, this code seems to conform to Martin's other requirements of clean code, even though he's arguing it does not. Can someone please explain what I am missing? Thanks.

  • ie8 breaks with asp.net ajax

    - by Amadeo Torese
    Hello, When using asp.net ajax (scriptmanager, timer, updatepanel) with ie8, after certain time (~3h) IE breaks with null object, constructor, or paramArray (depending on the asp.net code). Even with the simplest timer (no ajax, no updatepanel) ie8 still breaks. On every other browser it works fine, and if I code the ajax myself it works. Since google and msdn forums turned up nothing I'm wondering if anybody here has had similar problems with ie8 browser.

    This is my first silverlight Application. I am trying to use Rating Control from 3.0 Toolkit with VisualStudio 2008 Here are the problems: I am unable to see designer view after adding Rating Control and few other controls. I am not getting any errors or warnings on markup or while compiling. Trying to access Property window for any control is giving me this message " Property Editing not available". Is this the way silverlight was made available with Visual Studio or is there something I am missing here?

  • Backgroundworker abort

    - by MazarD
    Hi, I recently tried to use backgroundworker instead of "classic" threads and I'm realizing that it's causing, at least for me, more problems than solutions. I have a backgroundworker running a synchronous read (in this case from serialPort) and getting blocked around 30 seconds in 1 code line, then cancellationpending isn't the solution. I'm seeing that if the application gets closed at this point (either with the cross button and Application.Exit()) the process keeps zombie forever. I need a way to force abort or to kill the backgroundworker thread.

  • php includes that include another php file

    - by Emma
    I'm getting really muddled up now and my brain hurts! :( lol Root: index.php Includes: cat.php dog.php index includes dog: include("includes/dog.php"); dog includes cat: include("cat.php"); When I run index, for cat it says: A link to the server could not be established Access denied for user ... However, if I run dog, I get no problems... I'm guessing its the path, but i've tried ./includes/cat.php to no joy...

  • Decimal point issue on cocoa app

    - by Manuel Rocha
    I there, I'm trying making my first cocoa app, but I'm having problems with float numbers because of the regional settings. If I write on the TextBox the float number 1.2 I only can get the number 1, but If I write on the same TextBox the same float number but this time with the ',' sign instead (1,2) I can get the right float value. How can I bypass the regional settings? Kind Regards, Manuel Rocha

  • Node.js as a custom (streaming) upload handler for Django

    - by Gijs
    I want to build an upload-centric app using Django. One way to do this is with nginx's upload module (nonblocking) but it has its problems. Node.js is supposed to be a good candidate for this type of application. But how can I make node.js act as an upload_handler() for Django (http://docs.djangoproject.com/en/1.1/topics/http/file-uploads/#modifying-upload-handlers-on-the-fly) I'm not sure where to look for examples?

  • Android Programming: Stay with CyanogenMod?

    - by Android Eve
    My new Nexus One came pre-installed with CyanogenMod. It's great so far, but since I bought it for software development purposes (initially just learning how to program for Android), should I stay with it, or install the official Android OS? If the latter, 2.2 or 2.3? My main concern is compatibility issues with documented API, that is wasting time on debugging problems that shouldn't have been there in the first place.

  • Jython webapp performance

    - by DrPep
    I'm currently building a Jython web app but am concerned about Jython application performance. I take some comfort in that any compute intensive tasks I can write in a separate Java jar and invoke them from Jython. Has anyone had problems doing this, or forsee issues with such a setup?

  • fork() in perl on windows

    - by Darioush
    I'm using fork() on PERL in windows (activeperl) for a basic socket server, but apparently there are problems (it won't accept connections after a few times), is there any workaround? while($client = $bind->accept()) { $client->autoflush(); if(fork()){ $client->close(); } else { $bind->close(); new_client($client); exit(); } } is the portion of the relevant code.

  • Drawing scaled emoji icons on iOS

    - by Eimantas
    I'm trying to implement my own emoji icon keyboard and have some problems. I'm trying to draw emoji icons at the same size as on native iOS emoji keyboard, but when doing simple drawing (standard unicode characters like "\ue415") icons always appear at original size. When trying to increase the font - emoji icons stay of the same size. When applying CGAffineTransform for scaling - drawn icons are bigger, but pixelated and blurred. How should I go about drawing emoji icons bigger, but sharper?
