  • Rspec Selenium. Test to check certain Ajax functions passes when i expect it to fail.

    - by alokswain
    I am testing a Ajax action using Rspec and Selenium. My story is as follows: it "should create a new User with any input" do @browser.open "/people" @browser.wait_for_page_to_load "2000" @browser.type "user_name", "Alok Swain" @browser.click "user_submit" @browser.text?("Alok Swain").should be_true end The action i am testing is: def add_user @users = User.all User.create(params[:user]) render :update do |page| page.alert "Created User" page.replace_html "users", :partial => '/people/users_list', :locals => {:users => @users} end end The test fails and the error I get is: 'User should create a new User with any input' FAILED expected false to be true. This test should pass right ? I also kept an alert and tried @browser.is_alert_present.should be_true but i got the same error. I tried @browser.is_text_present("test") and this test succeeded. In the test database a record was created for Alok Swain but when I tried the above assertion it passed when i expected it to fail. Is there any thing else to be done here. What am I missing ?

  • Sequential animations in Jquery

    - by Pickels
    I see a lot people struggling with this(me included). I guess it's mostly due to not perfectly knowing how Javascript scopes work. An image slideshow is a good example of this. So lets say you have series of images, the first one fades in = waits = fades out = next image. When I first created this I was already a little lost. I think the biggest problem for creating the basics is to keep it clean. I noticed working with callbacks can get uggly pretty fast. So to make it even more complicated most slideshows have control buttons. Next, previous, go to img, pause, ... I've been trying this for a while now and this is where I got: $(InitSlideshow); function InitSlideshow() { var img = $("img").hide(); var animate = { wait: undefined, start: function() { img.fadeIn(function() { animate.middle(); }); }, middle: function() { animate.wait = setTimeout(function() { animate.end(); }, 1000); }, end: function() { img.fadeOut(function() { animate.start(); }); }, stop: function() { img.stop(); clearTimeout(animate.wait); } }; $("#btStart").click(animate.start); $("#btStop").click(animate.stop); }; This code works(I think) but I wonder how other people deal with sequentials animations in Jquery? Tips and tricks are most welcome. So are links to good resources dealing with this issue. If this has been asked before I will delete this question. I didn't find a lot of info about this right away. I hope making this community wiki is correct as there is not one correct answer to my question. Kind regards, Pickels

  • Where to post code for open source usage?

    - by Douglas
    I've been working for a few weeks now with the Google Maps API v3, and have done a good bit of development for the map I've been creating. Some of the things I've done have had to be done to add usability where there previously was not any, at least not that I could find online. Essentially, I made a list of what had to be done, searched all over the web for the ways to do what I needed, and found that some were not(at the time) possible(in the "grab an example off the web" sense). Thus, in my working on this map, I have created a number of very useful tools, which I would like to share with the development community. Is there anywhere I could use as a hub, apart from my portfolio ( http://dougglover.com ), to allow people to view and recycle my work? I know how hard it can be to need to do something, and be unable to find the solution elsewhere, and I don't think that if something has been done before, it should necessarily need to be written again and again. Hence open source code, right? Firstly, I was considering coming on here and asking a question, and then just answering it. Problem there is I assume that would just look like a big reputation grab. If not, please let me know and I'll go ahead and do that so people here can see it. Other suggestions appreciated. Some stuff I've made: A (new and improved) LatLng generator Works quicker, generates LatLng based on position of a draggable marker Allows searching for an address to place the marker on/near the desired location(much better than having to scroll to your location all the way from Siberia) Since it's a draggable marker, double-clicking zooms in, instead of creating a new LatLng marker like the one I was originally using The ability to create entirely custom "Smart Paths" Plot LatLng points on the map which connect to each other just like they do using the actual Google Maps Using Dijkstra's algorithm with Javascript, the routing is intelligent and always gives the shortest possible route, using the points provided Simple, easy to read multi-dimensional array system allows for easily adding new points to the grid Any suggestions, etc. appreciated.

  • Audio output from Silverlight

    - by leecarter
    I'm looking to develop a Silverlight application which will take a stream of data (not an audio stream as such) from a web server. The data stream would then be manipulated to give audio of a certain format (G.711 a-Law for example) which would then be converted into PCM so that additional effects can be applied (such as boosting the volume). I'm OK up to this point. I've got my data, converted the G.711 into PCM but my problem is being able to output this PCM audio to the sound card. I basing a solution on some C# code intended for a .Net application but in Silverlight there is a problem with trying to take a copy of a delegate (function pointer) which will be the topic of a separate question once I've produced a simple code sample. So, the question is... How can I output the PCM audio that I have held in a data structure (currently an array) in my Silverlight to the user? (Please don't say write the byte values to a text box) If it were a MP3 or WMA file I would play it using a MediaElement but I don't want to have to make it into a file as this would put a crimp on applying dynamic effects to the audio. I've seen a few posts from people saying low level audio support is poor/non-existant in Silverlight so I'm open to any suggestions/ideas people may have.

  • I'm trying to build a query to search against a fulltext index in mysql

    - by Rockinelle
    The table's schema is pretty simple. I have a child table that stores a customer's information like address and phone number. The columns are user_id, fieldname, fieldvalue and fieldname. So each row will hold one item like phone number, address or email. This is to allow an unlimited number of each type of information for each customer. The people on the phones need to look up these customers quickly as they call into our call center. I have experimented with using LIKE% and I'm working with a FULLTEXT index now. My queries work, but I want to make them more useful because if someone searches for a telephone area code like 805 that will bring up many people, and then they add the name Bill to narrow it down, '805 Bill'. It will show EVERY customer that has 805 OR Bill. I want it to do AND searches across multiple rows within each customer. Currently I'm using the query below to grab the user_ids and later I do another query to fetch all the details for each user to build their complete record. SELECT DISTINCT `user_id` FROM `user_details` WHERE MATCH (`fieldvalue`) AGAINST ('805 Bill') Again, I want to do the above query against groups of rows that belong to a single user, but those users have to match the search keywords. What should I do?

  • Why open source it? And how to get real involvement?

    - by donpal
    For me the main goal of open sourcing something is collaboration. If the most that other developers are going to do is take it and use it and report bugs to me, then I might as well close source it. Closed source provides me with all that. I was recently looking at a small javascript library (or more like a plugin, 1000 lines of code) that's actually quite popular. There were some bugs in it because new browsers and browser versions get released everyday and these bugs just pop up as a result. What bothered me is that these bugs would actually be quite easy to fix by even intermediate javascript developers, but for an entire month no one stepped up to fix the bug and submit the fixed version. The original author was apparently busy for that month, but that's the point of open sourcing your code: so that others can use it and help themselves AND the project if they can. So this makes me doubt the promise of open source. If people aren't working on it too, I might as well close source my new projects. And how do you get people involved so that open sourcing is worth it?

  • Building a ctypes-"based" C library with distutils

    - by Robie Basak
    Following this recommendation, I have written a native C extension library to optimise part of a Python module via ctypes. I chose ctypes over writing a CPython-native library because it was quicker and easier (just a few functions with all tight loops inside). I've now hit a snag. If I want my work to be easily installable using distutils using python setup.py install, then distutils needs to be able to build my shared library and install it (presumably into /usr/lib/myproject). However, this not a Python extension module, and so as far as I can tell, distutils cannot do this. I've found a few references to people other people with this problem: Someone on numpy-discussion with a hack back in 2006. Somebody asking on distutils-sig and not getting an answer. Somebody asking on the main python list and being pointed to the innards of an existing project. I am aware that I can do something native and not use distutils for the shared library, or indeed use my distribution's packaging system. My concern is that this will limit usability as not everyone will be able to install it easily. So my question is: what is the current best way of distributing a shared library with distutils that will be used by ctypes but otherwise is OS-native and not a Python extension module? Feel free to answer with one of the hacks linked to above if you can expand on it and justify why that is the best way. If there is nothing better, at least all the information will be in one place.

  • Secure web module for paid subscribtion

    - by DarkJaff
    Hello everyone, I'm building a website (a community web site like digg) but we will soon release a new feature that people will need to pay for. Right now, our website is in pure C# in .NET, very simple pages with some AJAX. When the member log in, there is no HTTPS. Everything is check with session and the internal validation that I do. What we need, is that when the people are logged in, they can click on a link a proceed to a payment (Paypal, credit card, etc). After the payment is done, the "billing module" will return a value to my site to validate that the payment is done so the account will be flagged as "paying member". I'm guessing this is the way to do, maybe I'm wrong! So my questions are: -What is the name of this kind of billing module? (I will do some research on that) -Do you know any ready to go module that does this kind of thing? -(I push my luck) Do you know any FREE module that do this kind of things. If something is not clear, don't hesitate to ask question :) Thanks a lot! DarkJaff

  • Catch a thread's exception in the caller thread in Python

    - by Mikee
    Hi Everyone, I'm very new to Python and multithreaded programming in general. Basically, I have a script that will copy files to another location. I would like this to be placed in another thread so I can output "...." to indicate that the script is still running. The problem that I am having is that if the files cannot be copied it will throw an exception. This is ok if running in the main thread; however, having the following code does not work: try: threadClass = TheThread(param1, param2, etc.) threadClass.start() ##### **Exception takes place here** except: print "Caught an exception" In the thread class itself, I tried to re-throw the exception, but it does not work. I have seen people on here ask similar questions, but they all seem to be doing something more specific than what I am trying to do (and I don't quite understand the solutions offered). I have seen people mention the usage of sys.exc_info(), however I do not know where or how to use it. All help is greatly appreciated! EDIT: The code for the thread class is below: class TheThread(threading.Thread): def __init__(self, sourceFolder, destFolder): threading.Thread.__init__(self) self.sourceFolder = sourceFolder self.destFolder = destFolder def run(self): try: shul.copytree(self.sourceFolder, self.destFolder) except: raise

  • ASP.Net MVC: Showing the same data using different layouts...

    - by vdh_ant
    Hi guys I'm wanting to create a page that allows the users to select how they would like to view their data - i.e. summary (which supports grouping), grid (which supports grouping), table (which supports grouping), map, time line, xml, json etc. Now each layout would probably have different use a different view model, which inherit from a common base class/view model. The reason being that each layout needs the object structure that it deals with to be different (some need hierarchical others a flatter structure). Each layout would call the same repository method and each layout would support the same functionality, i.e. searching and filtering (hence these controls would be shared between layouts). The main exception to this would be sorting which only grid and table views would need to support. Now my question is given this what do people think is the best approach. Using DisplayFor to handle the rendering of the different types? Also how do I work this with the actions... I would imagine that I would use the one action, and pass in the layout types, but then how does this support the grouping required for the summary, grid and table views. Do i treat each grouping as just a layout type Also how would this work from a URL point of view - what do people think is the template to support this layout functionality Cheers Anthony

  • Why does Microsoft advise against readonly fields with mutable values?

    - by Weeble
    In the Design Guidelines for Developing Class Libraries, Microsoft say: Do not assign instances of mutable types to read-only fields. The objects created using a mutable type can be modified after they are created. For example, arrays and most collections are mutable types while Int32, Uri, and String are immutable types. For fields that hold a mutable reference type, the read-only modifier prevents the field value from being overwritten but does not protect the mutable type from modification. This simply restates the behaviour of readonly without explaining why it's bad to use readonly. The implication appears to be that many people do not understand what "readonly" does and will wrongly expect readonly fields to be deeply immutable. In effect it advises using "readonly" as code documentation indicating deep immutability - despite the fact that the compiler has no way to enforce this - and disallows its use for its normal function: to ensure that the value of the field doesn't change after the object has been constructed. I feel uneasy with this recommendation to use "readonly" to indicate something other than its normal meaning understood by the compiler. I feel that it encourages people to misunderstand the meaning of "readonly", and furthermore to expect it to mean something that the author of the code might not intend. I feel that it precludes using it in places it could be useful - e.g. to show that some relationship between two mutable objects remains unchanged for the lifetime of one of those objects. The notion of assuming that readers do not understand the meaning of "readonly" also appears to be in contradiction to other advice from Microsoft, such as FxCop's "Do not initialize unnecessarily" rule, which assumes readers of your code to be experts in the language and should know that (for example) bool fields are automatically initialised to false, and stops you from providing the redundancy that shows "yes, this has been consciously set to false; I didn't just forget to initialize it". So, first and foremost, why do Microsoft advise against use of readonly for references to mutable types? I'd also be interested to know: Do you follow this Design Guideline in all your code? What do you expect when you see "readonly" in a piece of code you didn't write?

  • How to send parameters with same encoding from javascript?

    - by nimcap
    I have a javascript file that lots of people have embedded to their pages. Since I am hosting the file, I have control over that javascript file; I cannot control the way it is embedded because lots of people is using it already. This javascript file sends GET requests to my servlets, and the parameters passed with the request are recorded to DB. For example, javascript sends a request to http://myserver.com/servlet?p1=123&p2=aString and then servlet records 123 and aString to DB somehow. Before sending strings I use encodeURIComponent() to encode it. But what I figured out is every client sends the same string with different encodings depending on either their browser or the site they are visiting. As a result, same strings are represented with different characters when it reaches servlet (so they are different strings). What I am trying to do is to convert the strings to one kind of encoding from javascript so when they reach the client same words are represented with same characters. How is this possible? PS. If there is a way to convert the encoding from Java it is also applicable.

  • Git-Based Source Control in the Enterprise: Suggested Tools and Practices?

    - by Bob Murphy
    I use git for personal projects and think it's great. It's fast, flexible, powerful, and works great for remote development. But now it's mandated at work and, frankly, we're having problems. Out of the box, git doesn't seem to work well for centralized development in a large (20+ developer) organization with developers of varying abilities and levels of git sophistication - especially compared with other source-control systems like Perforce or Subversion, which are aimed at that kind of environment. (Yes, I know, Linus never intended it for that.) But - for political reasons - we're stuck with git, even if it sucks for what we're trying to do with it. Here are some of the things we're seeing: The GUI tools aren't mature Using the command line tools, it's far to easy to screw up a merge and obliterate someone else's changes It doesn't offer per-user repository permissions beyond global read-only or read-write privileges If you have a permission to ANY part of a repository, you can do that same thing to EVERY part of the repository, so you can't do something like make a small-group tracking branch on the central server that other people can't mess with. Workflows other than "anything goes" or "benevolent dictator" are hard to encourage, let alone enforce It's not clear whether it's better to use a single big repository (which lets everybody mess with everything) or lots of per-component repositories (which make for headaches trying to synchronize versions). With multiple repositories, it's also not clear how to replicate all the sources someone else has by pulling from the central repository, or to do something like get everything as of 4:30 yesterday afternoon. However, I've heard that people are using git successfully in large development organizations. If you're in that situation - or if you generally have tools, tips and tricks for making it easier and more productive to use git in a large organization where some folks are not command line fans - I'd love to hear what you have to suggest. BTW, I've asked a version of this question already on LinkedIn, and got no real answers but lots of "gosh, I'd love to know that too!"

  • Inconsistent behavior working with "Flex on Rails" example.

    - by kmontgom
    I'm experimenting with Flex and Rails right now (Rails is cool). I'm following the examples in the book "Flex on Rails", and I'm getting some puzzling and inconsistent behavior. Heres the Flex MXML: <mx:HTTPService id="index" url="http://localhost:3000/people.xml" resultFormat="e4x" /> <mx:DataGrid dataProvider="{index.lastResult.person}" width="100%" height="100%"> <mx:columns> <mx:DataGridColumn headerText="First Name" dataField="first-name"/> <mx:DataGridColumn headerText="Last Name" dataField="last-name"/> </mx:columns> </mx:DataGrid> <mx:Script> <![CDATA[ import mx.controls.Alert; private function main():void { Alert.show( "In main()" ); } ]]> </mx:Script> When I run the app from my IDE (Amythyst beta, also cool), the DataGrid appears, but is not populated. The Alert.show() also triggers. When I go out to a web browser and manually enter the url (http://localhost:3000/people.xml), the Mongrel console shows the request coming through and the browser shows the web response. No exceptions or other error messages occur. Whats the difference? Do I need to alter some OS setting? I'm using Win7 on an x64 machine.

  • Multiple page technique

    - by the Hampster
    Six years ago I wrote an large web application. It was my very first php program, and it grew, and grew. I used a lot of forms, and some very (atrocious) techniques to give an AJAX "look" to the site, and to handle multiple users with various permissions. I am looking to expand this, and sell it to other companies in the field, but I need to seriously modernize it. Currently, it loads index.php where you log in. The user can then select from various "students" or "participants" (We work with people with disabilities). From there, you can select different lesson plans or life skills that are being worked on. There are many other branches as well. At each stage, a different page is served: Sel_Paricipant.php, Sel_Program.php, etc. Are there any fundamental problems with doing it this way? If so, what are some good techniques for eliminating this, so that people only see the TLD in their address bar? Thanks in advance. --Dave

  • Why would this Lua optimization hack help?

    - by Ian Boyd
    i'm looking over a document that describes various techniques to improve performance of Lua script code, and i'm shocked that such tricks would be required. (Although i'm quoting Lua, i've seen similar hacks in Javascript). Why would this optimization be required: For instance, the code for i = 1, 1000000 do local x = math.sin(i) end runs 30% slower than this one: local sin = math.sin for i = 1, 1000000 do local x = sin(i) end They're re-declaring sin function locally. Why would this be helpful? It's the job of the compiler to do that anyway. Why is the programmer having to do the compiler's job? i've seen similar things in Javascript; and so obviously there must be a very good reason why the interpreting compiler isn't doing its job. What is it? i see it repeatedly in the Lua environment i'm fiddling in; people redeclaring variables as local: local strfind = strfind local strlen = strlen local gsub = gsub local pairs = pairs local ipairs = ipairs local type = type local tinsert = tinsert local tremove = tremove local unpack = unpack local max = max local min = min local floor = floor local ceil = ceil local loadstring = loadstring local tostring = tostring local setmetatable = setmetatable local getmetatable = getmetatable local format = format local sin = math.sin What is going on here that people have to do the work of the compiler? Is the compiler confused by how to find format? Why is this an issue that a programmer has to deal with? Why would this not have been taken care of in 1993? i also seem to have hit a logical paradox: Optimizatin should not be done without profiling Lua has no ability to be profiled Lua should not be optimized

  • Multi-account sync with Dropbox API

    - by Dan
    I'm trying to create a web app that lets users share files with each other through Dropbox. At the moment, Dropbox handles all the sharing, and there's one central Dropbox account running on the web server that shares the folder with the people who want it. I'm trying to change it so people don't have to accept a new folder invitation each time. I'd like to have them authorize my app to access an app folder in their Dropbox account, and all their shared folders would go inside there. Any changes they make would get noticed by the app on the server and synced to everyone else's folders. There's a couple things I'm having trouble figuring out to make this work: Do I need to make repeated calls to /delta for every account? I can't think how else I'd do this, but that sounds like it would quickly turn into thousands of requests a minute just polling for updates. When someone adds a file, do I have to upload it once for each account? That seems like a huge waste of bandwidth. I've looked into using /copy_ref, which I think would add a file to another user's account without my app ever touching it, but my app's web interface also allows users to upload files directly to my server, which would then need to be synced with everyone else's folders. That file isn't on Dropbox's servers yet, so /copy_ref obviously wouldn't work. For a little extra context, my app is written in node.js, and I've been playing with this library to interface with Dropbox, which uses their REST API.

  • Webforms vs. MVC. Once you start using MVC.. Do you ever go back to webforms?

    - by punkouter
    I checked out MVC months ago and didn't really get it.. but recently as I have become a better programmer I think it is making sense.. Here is my theory.. tell me if I got it Right In the 90s for Microsoft Devs we had Classic ASP. This mixed VBscript and HTML on the same page. So you needed to create all the HTML yourself and mix HTML and VBScript. This was not considered Ideal. Then .NET came along and everyone liked it because it was similiar to event driven VB 6 style programming. It created this abstraction of binding data to ASP Servier controls. It made getting Enumerated data easy to get on the screen with one line. Then recently Jquery and SOA concepts are mixed together.. Now people think.. Why create this extra layer of abstraction when I can just directly use .NET as a data provider and use jquery AJAX calls to get the data and create the HTML with it directly .. no need for the Webforms abstraction layer.. Sowe are back to creating HTML directly like we did in 1999. So MVC is all about saying Stop pretending like WEb programming is a VB6 app! Generate HTML directly! Am I missing anything? So I wonder.. for you people out there using MVC... is it the sort of things that once you get used to it you never want to go back to webforms??

  • Non-english domain naming issues in programming

    - by Svend
    Most programming code, I imagine is written in english. But I'm curious how people handling the issue of naming herein. Alot of programming is done within some bussiness domain, usually with well established terms for certain procedures, items. I'm from Denmark for instance, and something I work alot with has a term called "indblikskode", which sorta translates to "insight code". So, do I use the line "string indblikskode = ..." in the C# code for some webservice related to this? Or do I try to use a translation, such as "insightcode"? The bussiness I'm in isn't even consistent in it's language, for instance using the term "organisatorisk enhed" (organizatorical unit), but just as often using the abbreviation "OU", which is obviously abbreviated from the english. How do other people handle this naming issue, while keeping consistent, and sane (in everything from simple variable names in your code, to database tables, to server names)? Duplicates: Should identifiers and comments be always in English or in the native language of the application and developers? Do you use another language instead of english ?

  • Is there a practical benefit to casting a NULL pointer to an object and calling one of its member fu

    Ok, so I know that technically this is undefined behavior, but nonetheless, I've seen this more than once in production code. And please correct me if I'm wrong, but I've also heard that some people use this "feature" as a somewhat legitimate substitute of a lacking aspect of the current C++ standard, namely, the inability to obtain the address (well, offset really) of a member function. For example, this is out of a popular implementation of a PCRE (Perl-compatible Regular Expression) library: #ifndef offsetof #define offsetof(p_type,field) ((size_t)&(((p_type *)0)->field)) #endif One can debate whether the exploitation of such a language subtlety in a case like this is valid or not, or even necessary, but I've also seen it used like this: struct Result { void stat() { if(this) // do something... else // do something else... } }; // ...somewhere else in the code... ((Result*)0)->stat(); This works just fine! It avoids a null pointer dereference by testing for the existence of this, and it does not try to access class members in the else block. So long as these guards are in place, it's legitimate code, right? So the question remains: Is there a practical use case, where one would benefit from using such a construct? I'm especially concerned about the second case, since the first case is more of a workaround for a language limitation. Or is it? PS. Sorry about the C-style casts, unfortunately people still prefer to type less if they can.

  • Code smells galore. Can this be a good company?

    - by Paperflyer
    I am currently doing some contract work for a company. Now they want to hire me for real. I have been reading on SO about code smells lately. The thing is, I have worked with some of their code and it smells. Badly. They use incredibly old versions of MSVC (2003), they do not seem to use version control systems, most code is completely undocumented, variable names with more than three letters are a rarity, there is commented out code all over the place, some methods take huge amounts of arguments, UI design is seemingly done by blind people... Yet they seem to be quite successful with what they do and their actual algorithms seem to be pretty sound and rather sophisticated. Since they mostly do DSP stuff, I am willing to ignore the UI side of things, but really these code smells are worrying. What would you think of a company that doesn't seem to value readable code? The people are nice enough and payment would be good. How much would you value code smells in this context? You see, this is my first job and SO got me worried, so I turn to you for suggestions ;-)

  • Developing Job References

    - by Joe Smith
    How do you develop references for jobs? I have 6 years of programming experience spanning two jobs, but sadly I don't have a lot of people I can draw on as references. It's been several years since I left my last job, which was at a small company, and I've lost touch with the few people I knew there. I now work at another small company. I think I've gone as far as I can in my current position, and would like to look for greener pastures, but I can't exactly use my current boss as a reference, even though I have a very good repore with him. I'm sure he'd make a great reference down the road, but I'm afraid I'd insult him or jeopardize my current job by mentioning that I'm thinking of leaving and would like him to help me. I've applied to some jobs, and I have gotten several replies like, "Oh, you're exactly what we're looking for. Send us a couple references and we'll schedule an interview. Oh, no references? You must be a psychopath, nevermind." I've tried doing some small freelance work on the side, just so I can have a contact who can vouch for my work, but the competition for even small projects is pretty fierce and I can rarely devote adequate time to freelancing while holding a full time job. In addition, I often encounter a Catch-22 where a lot of freelancing jobs also require references. So how do programmers maintain existing references and develop new ones, especially while holding a full time job?
