  • Dynamically pulling images from XML for iPhone App

    - by Simon Hume
    I've got my iPhone app pulling down live data content via XML nicely, and I've formatted the UITableView cells to display the content without too many headaches. However, at the moment, for each cell I'm just showing a default graphic for now, but I want this to be pulled down from my server too. The code snippet that grabs the image (which is actually in my project) is: cell.imageView.image = [UIImage imageNamed:@"TBC.png"]; But that will need to be the dynamic image. In my XML, am I better just returning 'mypic.png' and let the SDK determine the full path, like http://myapp.com/mypic.png or storing the full URL to the image in the XML?

  • Using JUnit as an acceptance test framework

    - by Chris Knight
    OK, so I work for a company who has openly adopted agile practices for development in recent years. Our unit tests and code quality are improving. One area we still are working on is to find what works best for us in the automated acceptance test arena. We want to take our well formed user stories and use these to drive the code in a test driven manner. This will also give us acceptance level tests for each user story which we can then automate. To date, we've tried Fit, Fitnesse and Selenium. Each have their advantages, but we've also had real issues with them as well. With Fit and Fitnesse, we can't help but feel they overcomplicate things and we've had many technical issues using them. The business haven't fully bought in these tools and aren't particularly keen on maintaining the scripts all the time (and aren't big fans of the table style). Selenium is really good, but slow and relies on real time data and resources. One approach we are now considering is the use of the JUnit framework to provide similiar functionality. Rather than testing just a small unit of work using JUnit, why not use it to write a test (using the JUnit framework) to cover an acceptance level swath of the application? I.e. take a new story ("As a user I would like to see basic details of my policy...") and write a test in JUnit which starts executing application code at the point of entry for the policy details link but covers all code and logic down to the stubbed data access layer and back to the point of forwarding to the next page in the application, asserting on what data the user should see on that page. This seems to me to have the following advantages: Simplicity (no additional frameworks required) Zero effort to integrate with our Continuous Integration build server (since it already handles our JUnit tests) Full skillset already present in the team (its just a JUnit test after all) And the downsides being: Less customer involvement (though they are heavily involved in writing the user stories in the first place from which the acceptance tests will be written) Perhaps more difficult to understand (or make understood) the user story and acceptance criteria in a JUnit class verses a freetext specification ala Fit or Fitnesse So, my question is really, have you ever tried this method? Ever considered it? What are your thoughts? What do you like and dislike about this approach? Finally, please only mention alternative frameworks if you can say why you like or dislike them more than this approach.

  • C# - Angle between two 2d vectors, diff between two methods?

    - by Sean Ochoa
    Hey all. I've got this code snippet, and I'm wondering why the results of the first method differ from the results of the second method, given the same input? public double AngleBetween_1(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = Len*b.Len; var divOperation = dotProd/lenProd; return Math.Acos(divOperation) * (180.0 / Math.PI); } public double AngleBetween_2(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = Len*b.Len; var divOperation = dotProd/lenProd; return (1/Math.Cos(divOperation)) * (180.0 / Math.PI); }

  • No norwegian characters in LaTeX

    - by DreamCodeR
    Hi, I have translated a document from English to Norwegian in the LaTeX format, and while using norwegian special characters, I get an error using \usepackage[utf8x]{inputenc} to try and display the norwegian (scandinavian) special characters in PostScript/PDF/DVI format, saying Package utf8x Error: MalformedUTF-8sequence. So while that didn't work, I tried out another possible solution: \usepackage{ucs} \usepackage[norsk]babel And when I tried to save that in Emacs I get this message: These default coding systems were tried to encode text in the buffer `lol.tex': (utf-8-unix (905 . 4194277) (916 . 4194245) (945 . 4194278) (950 . 4194277) (954 . 4194296) (990 . 4194277) (1010 . 4194277) (1013 . 4194278) (1051 . 4194277) (1078 . 4194296) (1105 . 4194296)) However, each of them encountered characters it couldn't encode: utf-8-unix cannot encode these: \345 \305 \346 \345 \370 \345 \345 \346 \345 \370 ... Thanks to Emacs I have the possibility to check out the properties of those characters and the first one tells me: character: \345 (4194277, #o17777745, #x3fffe5) preferred charset: eight-bit (Raw bytes 128-255) code point: 0xE5 syntax: w which means: word buffer code: #xE5 file code: not encodable by coding system utf-8-unix display: not encodable for terminal Which doesn't tell me much. When I try to build this with texi2dvi --dvipdf filename.text I get a perfectly fine PDF, all without the special norwegian characters. When I am about to save Emacs also ask me: "Select coding system (default raw-text):" And I type in utf-8 to choose its coding system. I have also tried to choose default raw-text to see if I get some different result. But nothing. At last I tried \lstset{inputencoding=utf8x, extendedchars=\true} ... a code I came over while trying to google the solution to this problem. Which gives me this error: Undefined control sequence. So basically, I have tried every encoding option I have been able to find and nothing works. I am desperately trying to make this work since the norwegian translation must be published before the deadline. As an additional information I may add that I found out later on that I only had the en_US.UTF-8 in my locale, so I added nb_NO.UTF-8 and nb_NO.ISO-8859-15 and ran locale-gen + reboot without any changes. I hope I provided enough information to get some assistance, the characters in question is æ ø å.

  • Immediately tell which output was sent to stderr

    - by Clinton Blackmore
    When automating a task, it is sensible to test it first manually. It would be helpful, though, if any data going to stderr was immediately recognizeable as such, and distinguishable from the data going to stdout, and to have all the output together so it is obvious what the sequence of events is. One last touch that would be nice is if, at program exit, it printed its return code. All of these things would aid in automating. Yes, I can echo the return code when a program finishes, and yes, I can redirect stdout and stderr; what I'd really like it some shell, script, or easy-to-use redirector that shows stdout in black, shows stderr interleaved with it in red, and prints the exit code at the end. Is there such a beast? [If it matters, I'm using Bash 3.2 on Mac OS X]. Update: Sorry it has been months since I've looked at this. I've come up with a simple test script: #!/usr/bin/env python import sys print "this is stdout" print >> sys.stderr, "this is stderr" print "this is stdout again" In my testing (and probably due to the way things are buffered), rse and hilite display everything from stdout and then everything from stderr. The fifo method gets the order right but appears to colourize everything following the stderr line. ind complained about my stdin and stderr lines, and then put the output from stderr last. Most of these solutions are workable, as it is not atypical for only the last output to go to stderr, but still, it'd be nice to have something that worked slightly better.

  • $_SERVER['HTTP_X_REQUESTED_WITH'] seemingly not available on PHP 5.1.6

    - by kenny99
    Hi, I've run into a problem on a server running php 5.1.6 - the code i use to detect ajax requests isn't working as the $_SERVER['HTTP_X_REQUESTED_WITH'] variable is missing from the $_SERVER array. The same code works fine on php 5.2 and in firebug i can see the headers include X-Requested-With XMLHttpRequest. Anyone know any more about this issue and how I can get round it? Thanks in advance.

  • Form data sent to Node via Post is undefined

    - by user185812
    I know this has been asked countless times on here, however I tried all the solutions and am still having the issue.

  • Access denied error 3221225578 with file sharing to Windows server

    i'm trying to access the shares on a server. The credential box appears, and i enter in a correct username and password, and i get access denied. The silly thing is that i can Remote Desktop to the server (using the same credentials), and i can check the Security event log for the access denied errors: Event Type: Failure Audit Event Source: Security Event Category: Account Logon Event ID: 681 Date: 3/19/2011 Time: 11:54:39 PM User: NT AUTHORITY\SYSTEM Computer: STALWART Description: The logon to account: Administrator by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 from workstation: HARPAX failed.

What gives that i cannot access the server over file sharing, but i can access it over RDP?

  • Profiling python C extensions

    - by pygabriel
    I have developed a python C-extension that receives data from python and compute some cpu intensive calculations. It's possible to profile the C-extension? The problem here is that writing a sample test in C to be profiled would be challenging because the code rely on particular inputs and data structures (generated by python control code). Do you have any suggestions?

  • How to trim whitespace from bash variable?

    - by too much php
    I have a shell script with this code: var=`hg st -R "$path"` if [ -n "$var" ]; then echo $var fi But the conditional code always executes because hg st always prints at least one newline character. Is there a simple way to strip whitespace from $var (like trim() in php)? or Is there a standard way of dealing with this issue? I could use sed or awk, but I'd like to think there is a more elegant solution to this problem.

  • jsf flash.keep and redirects does not seem to work

    - by user384706
    Hi, I am trying to use JSF 2.0 flash via redirects. I have a class named UserBean (ManagedScoped and RequestScoped). It has a method called getValuesFromFlash which essentially gets the values from the flash and sets the coresponding properties of the UserBean public void getValuesFromFlash() { Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash(); firstName= (String) flash.get("firstName"); lastName = (String) flash.get("lastName"); } In the entry page the <h:inputText> are bound to the flash. Snippet follows: Entry.xhtml <h:form> <table> <tr> <td>First Name:</td> <td> <h:inputText id="fname" value="#{flash.firstName}" required="true"/> <h:message for="fname" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:inputText id="lname" value="#{flash.lastName}" required="true"/> <h:message for="lname" /> </td> </tr> </table <p><h:commandButton value="Submit" action="confirmation?faces-redirect=true" /></p> </h:form> In confirmation.xhtml these values are supposed to be displayed but they are not. Snippet follows: <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{flash.keep.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{flash.keep.lastName}"/> </td> </tr> </table> <h:form> <p><h:commandButton value="Confirm" action="finished?faces-redirect=true" /></p> </h:form> In finished.xhtml I want all these to be displayed so: <h:body> <h:form> #{userBean.getValuesFromFlash( )} <table> <tr> <td>First Name:</td> <td> <h:outputText value="#{userBean.firstName}" /> </td> </tr> <tr> <td>Last Name:</td> <td> <h:outputText value="#{userBean.lastName}"/> </td> </tr> </table> </h:form> </h:body> Instead when I get redirected to confirmation.xhtml neither first nor last name is displayed, despite I used flash.keep Also in finished.xhtml I get org.apache.el.parser.ParseException: Encountered " "(" "( "" at line 1, column 30. Was expecting one of: "}" ... "." If I remove the parenthesis from the expression #{userBean.getValuesFromFlash( )} and make it = #{userBean.getValuesFromFlash} javax.el.ELException: /done.xhtml: Property 'getValuesFromFlash' not found on type com.UserBean But why no property??It is a method! Why is the method not visible? What I am doing wrong here please? I am using JSF2.0 (MyFaces), Eclipse Helios and Tomcat 6 (Have also tried in Tomcat 7 but no luck). Any help is appreciated. Thanks!
