• Test flash notice in layout view spec (rspec2, rails3)

  - by jbpros

  Hi! I'd like to spec the fact that my application layout view prints out flash notices. However the following code does not run, the flash method does not exist in view specs (as opposed to controller specs where it works perfectly): describe 'layouts/application' do it "renders flash notices" do flash[:notice] = "This is a notice!" render response.should contain "This is a notice!" end end Is my code wrong or is it a "not-yet-implemented feature" in Rspec 2? I'm on Rails3 and Rspec2 from its master branch on Git. Thanks!

• Data Integration/EAI Project Lessons Learned

  - by Greg Harman

  Have you worked on a significant data or application integration project? I'm interested in hearing what worked for you and what didn't and how that affected the project both during and after implementation (i.e. during ongoing operation, maintenance and expansion). In addition to these lessons learned, please describe the project by including a quick overview of: The data sources and targets. Specifics are not necessary, but I'd like to know general technology categories e.g. RDBMS table, application accessed via a proprietary socket protocol, web service, reporting tool. The overall architecture of the project as related to data flows. Different human roles in the project (was this all done by one engineer? Did it include analysts with a particular expertise?) Any third-party products utilized, commercial or open source.

• Mixing static and dynamic endpoints in app.yaml file

  - by Greg

  I'm trying to describe endpoints in my App Engine app and am having difficulty for directory structures that mix static and dynamic content. But my yaml rules are conflicting with one another. Before I change my directory structure, does anyone have a recommendation? The goal is to create a directory that contains both documentation (static html files) and implementations. /api - /v1 - getitdone.py - doc.html - index.html What I think I should be doing with my application yaml... - url: /api/v1/getitdone script: api/v1/getitdone.py - url: /api/ static_files: api/index.html upload: api/index.html - url: /api static_dir: api But this causes the dynamic endpoints to fail. I'm assuming the static_dir reference is breaking it. How can I do this without describing every script and static file reference (I have many more than are listed here)?

• How do I create a class associated with a windows form in C#?

  - by xarzu

  Now that C++ development has become second nature to me, do I have to start from scratch with C#? Since the beginning of Visual Studio, there has been easy way to describe the shape of a Dialog (now called a Form) in the resource file and then use a wizard to create the corresponding C++ code. I kind of remember that in MFC it was pretty much a no-brainer to create a custom dialog with all the components you want and then all the associated code. If I have a C# app that has many forms that I want to bring to the screen based on the user's menu selections, how do I create a class associated with a windows form?

• 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

• Difference between 'scope' and 'namespace'?

  - by katriel

  What is the difference, in general, between the concepts of namespaces and scope? To my understanding, both describe the parts of a program in which a variable/object/method/function will be accessible. I understand that 'scope' tends to be a property of the variable (e.g., "This variable has global scope"), while a 'namespace' is a property of the program (e.g., "A Python function creates a local namespace"). Are there other differences? Global scope vs global namespace addresses a slightly narrower question: global namespaces in C++. http://www.alan-g.me.uk/tutor/tutname.htm states, There are a few very subtle differences between the terms but only a Computer Scientist pedant would argue with you, and for our purposes namespace and scope are identical. What are those subtle differences? Under what circumstances or with which kinds of languages do people use each concept?

• How should I compensate for a bad WSDL?

  - by Brabster

  I've come across several examples of SOAP-based web services where automated tooling fails to build a client that works. Investigating these examples leads me to believe that the WSDL the service uses to describe itself doesn't quite match the service that's being provided. Maybe a wrong type somewhere, a different data structure - something. I'm unsure what the most appropriate response is - if we assume that the obvious one (get the provider to fix their stuff) isn't available. Some options I can think of: Make a fixed WSDL? Hack the generated code? Any other options? No good options? What good experiences have people had? What works in a real environment? Thanks

• SQL syntax Newbie student

  - by sammysmall

  Describe the output of the following SQL query: select custId, name from customer where region = "New York" UNION select cust.custId, cust.name from customer cust where cust.custId IN (select cust_order.custId from customer_order cust_order, company_employee comp_emp where cust_order.salesEmpId = comp_emp.empId AND comp_emp.name = 'DANIEL'); My question is: at line from customer cust is cust referring to a column in the customer table... This is a homework question I have identified the components leading up to this line and I think that cust is a column in the customer table... I am not asking for an overall solution just a bit of encouragement if I am on the right track...

• How do I put my return data from an asmx into JSON? I'm having trouble finding decent literature

  - by jphenow

  I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance.

• What design pattern do you use the most?

  - by spoon16

  I'm interested in understanding what design patterns people find themselves using often. Hopefully this list will help other recognize common scenarios and the associated design pattern that can be used to solve them. Please describe a common problem you find yourself solving and the design pattern(s) you use to solve it. Links to blogs or documentation describing the pattern are also appreciated. Edit: Please expand on your answers a bit, I would like this to be a useful reference for someone who wants to learn more about design patterns and is curious on what situations a specific design pattern might be used. Nobody has linked to any "more learning" resources.

• How To Make NHibernate Automatically change an "Updated" column

  - by IanT8

  I am applying NHibernate to an existing project, where tables and columns are already defined and fixed. The database is MS-SQL-2008. NHibernate 2.1.2 Many tables have a column of type timestamp named "ReplicationID", and also a column of type datetime named "UpdatedDT". I understand I might be able to use the element of the mapping file to describe the "ReplicationID" column which will allow NHibernate to manage that column. Is it possible to make NHibernate automatically update the UpdatedDT column when the row is updated? I suppose I could try mapping the UpdatedDT property to be of type timestamp, but that have other side effects.

• Writing a simple RSpec test to check that Rake tasks are correct

  - by John Feminella

  I'm trying to be diligent about checking my rake tasks with RSpec tests, but in the process of feeling my way around I seem to have hit a wall. I've got a really simple RSpec test that looks like this: # ./test/meta_spec.rb describe "Rake tasks" do require 'rake' before(:each) do @rake = Rake::Application.new @rake.load_rakefile # => Error here! Rake.application = @rake end after(:each) do Rake.application = nil end it "should have at least one RSpec test to execute" do Rake.application["specs"].spec_files.size.should > 0 end end I have a simple task called "specs" defined in ./Rakefile.rb which has an RSpec task that includes all the *_spec.rb files. If I put the @rake.load_rakefile method in, I want that Rakefile to load. But instead it just bombs out. If I comment it out, however, the test fails because the "specs" task is (understandably) not defined. Where am I going wrong?

• http_post_data basic authentication?

  - by kristian nissen

  I have a remote service that I need to access, according to the documentation it's restricted using basic authentication and all requests have to be posted (HTTP POST). The documentation contains this code example - VB script: Private Function SendRequest(ByVal Url, ByVal Username, ByVal Password, ByVal Request) Dim XmlHttp Set XmlHttp = CreateObject("MSXML2.XmlHttp") XmlHttp.Open "POST", Url, False, Username, Password XmlHttp.SetRequestHeader "Content-Type", "text/xml" XmlHttp.Send Request Set SendRequest = XmlHttp End Function how can I accomplish this in PHP? When I post data to the remote server it replies: 401 Unauthorized Access which is fine because I'm not posting my user/pass just the data. Bu when I add my user/pass as it's describe here: http://dk.php.net/manual/en/http.request.options.php like this: $res = http_post_data('https://example.com', $data, array( 'Content-Type: "text/xml"', 'httpauth' => base64_encode('user:pass'), 'httpauthtype' => HTTP_AUTH_BASIC ) ); the protocol is https - I get a runtime error in return (it's a .Net service). I have tried it without the base64_encode but with the same result.

• Modeling software for network serialization protocol design

  - by Aurélien Vallée

  Hello, I am currently designing a low level network serialization protocol (in fact, a refinement of an existing protocol). As the work progress, pen and paper documents start to show their limits: i have tons of papers, new and outdated merged together, etc... And i can't show anything to anyone since i describe the protocol using my own notation (a mix of flow chart & C structures). I need a software that would help me to design a network protocol. I should be able to create structures, fields, their sizes, their layout, etc... and the software would generate some nice UMLish diagrams.

• 3D effect to distort paper

  - by donpal

  This may be a little hard to describe since I don't have a sample. I'm trying to find a math function or full 3d function in php or a similar language that can help me with the following effect: imagine if you were to take a flat sheet or paper and glue it on a glass of water. It wouldn't be flat any more. It would have a curve, and one of its sides might end up being slightly hidden. Anyone can refer me to a good library or resource on the web where such functions can be found?

• elisp newbie question: Can't find 'filename' function definition in org.el?

  - by Dave Paroulek

  I really love org-mode in emacs and want to customize a few things. While reading thru org.el, I'm finding several references to filename but can't find filename using describe-function? I'm sure there's a simple answer, but I'm just learning elisp and it's not obvious. Any insight into where filename is defined? And/or if it's not a function, what is it? For example, filename on line 25502: (filename (if to-buffer (expand-file-name (concat (file-name-sans-extension (or (and subtree-p (org-entry-get (region-beginning) "EXPORT_FILE_NAME" t)) (file-name-nondirectory buffer-file-name))) "." html-extension) (file-name-as-directory (or pub-dir (org-export-directory :html opt-plist))))))

• How to find a duplicate element in an array of shuffled consecutive integers?

  - by SysAdmin

  I recently came across a question somewhere Suppose you have an array of 1001 integers. The integers are in random order, but you know each of the integers is between 1 and 1000 (inclusive). In addition, each number appears only once in the array, except for one number, which occurs twice. Assume that you can access each element of the array only once. Describe an algorithm to find the repeated number. If you used auxiliary storage in your algorithm, can you find an algorithm that does not require it? what i am interested to know is the second part. i.e without using auxiliary storage . do you have any idea?

• Error in writting a class.

  - by Richard

  I am running through a tutorial online at http://www.sthurlow.com/python/lesson08/ and I believe I understand how classes work in python, at least to some degree but when I run this code: class Shape: def init(self,x,y): self.x = x self.y = y description = "This shape has not been described yet" author = "Nobody has claimed to make this shape yet" def area(self): return self.x * self.y def perimeter(self): return 2 * self.x + 2 * self.y def describe(self,text): self.description = text def authorName(self,text): self.author = text def scaleSize(self,scale): self.x = self.x * scale self.y = self.y * scale I get this error: Traceback (most recent call last): File "Y:/python/Shape.py", line 1, in -toplevel- class Shape: File "Y:/python/Shape.py", line 17, in Shape self.y = self.y * scale NameError: name 'self' is not defined Any Help would be great Thanks Richard

• Code completion in NetBeans' python plugin does not work properly

  - by T.K.

  I am asking on StackOverflow because surely I am doing something completely silly and I hope S.O. might provide me with a quick answer. I've installed the latest stable Python-plugin for NetBeans. It works great, and I tested code completion with various packages such as sys, os and so on. It works beautifully. However, it does not seem to pick up the code completion for the code in my own project. I created a package called mypackage (it has _init_.py as well), and in it I have a module called mymodule.py. Inside mymodule I've put a class called MyClass, complete with doc-strings and all. Please refer to this screenshot to describe what happens in code-completion: As you see, it's suggesting irrelevant things, as opposed to just MyClass. (Note that if I execute mymodule.MyClass() it works 100%, it's just that I would really like code completion on my own code) Hope I'm just doing something silly here... Any ideas?

• Specification: Use cases for CRUD

  - by Mario Ortegón

  I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

• Can one TabBarItem be used for two different ViewControllers?

  - by Kash

  I am creating an app with three tabBarItems, but I want to control four ViewControlers with three tabBars. I am trying to use one tabBar for two different viewcontrollers. I am able to change the tabBartitle and icon upon tap, but I cannot reset it so it can go back to it's previous status with previous title and icon. Also, I am confused about using the tabBarController or just tabBar and to call what function to reload/refresh the tabBar status and where exactly? I am fairly new to the iPhone SD, please describe your answer clearly any help will be highly appreciated.

• AVPlayer seeking to a different point after app resume

  - by CGuess

  I have an AVPlayer, the video in it is ~2 seconds long. After the video plays, if the app goes to the background and reenters the foreground I need the video to still be shown exactly as it was when the app was exited. The AVPlayer sticks around just fine, however when I reenter the app from the background the video appears to be seeked to the middle of the video. However, if I just play the video, it starts from the beginning, so it doesn't seem like it actually seeked and is just showing a preview image. I've tried to auto-seek the video to the end on relaunch but nothing happens . Nothing I can figure out or find in the docs would describe this behavior. Any tips on having the video launch either at the beginning or end?

• How to loop an executable command in the terminal in Linux?

  - by user1452373

  Let me first describe my situation, I am working on a Linux platform and have a collection of .bmp files that add one to the picture number from filename0022.bmp up to filename0680.bmp. So a total of 658 pictures. I want to be able to run each of these pictures through a .exe file that operates on the picture then kicks out the file to a file specified by the user, it also has some threshold arguments: lower, upper. So the typical call for the executable is: ./filter inputfile outputfile lower upper Is there a way that I can loop this call over all the files just from the terminal or by creating some kind of bash script? My problem is similar to this: Execute a command over multiple files with a batch file but this time I am working in a Linux command line terminal. Thank you for your help, Luke H

• How to build a programmer's wiki

  - by Llistes Sugra

  For years I've missed a wiki so everyone could describe the new tools programmed, the servers where they are running, svn information, the internal rules of programming, how-tos, code samples, etc. The wiki might be used for the dozen of programmers in the company and the externals. I've been using a pmwiki (easy install) and now I want a better approach. What wiki do you use? What plug-ins? Do you think there are better systems than wiki for this?

• Available message types in JMS?

  - by Caylem

  This is based on a past exam question. The question is asking to describe the four types of message available using JMS. The problem is it says the four, not just four. So it assumes their is only four, no more no less. However according to this site their seems to be five; streams maps text objects bytes *Another book states that XML is another potential type in future versions of JMS. Is XML already available? Am I missing something or is the question just wrong? Thanks.
