  • Django Fancy String Diff During Test Execution in Console

    - by Koobz
    Anyone know of any pre-existing tools out there what will highlight differences in output when running Django tests? I'm comparing some JSON output and it's tough to find things like extra spaces. I was about to just copy and paste this into an existing diff tool but I figured this might be on someone's radar.

  • RFCOMM Before Android 2.0?

    - by Brad Hein
    I have several apps which I wrote using the standard SDK. They all connect to RFCOMM devices using bluetooth, so at present, I can only support devices which are 2.0 or newer. What options are available for backporting a bluetooth app to pre-2.0 apps while re-writing as little code as possible? Thank you.

  • how to remove empty tags in input xml

    - by SGB
    My java module gets a huge input xml from a mainframe. Unfortunately, the mainframe is unable to skip optional elements when it is not a leaf node, with the result that I get a LOT of empty tags in my input : So, <pre><code><SSN>111111111</SSN> <Employment> <Current> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Current> <Previous> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Previous> </Employment> <MaritalStatus>Single</MaritalStatus> </code></pre> should be <SSN>111111111</SSN> <MaritalStatus>Single</MaritalStatus> I use jaxb to unmarshall the input xml string that the mainframe sends it. Is there a clean/ easy way to remove all the empty group tags, or do I have to do this manuall in the code for each element. I have over 35 elements in my input xml, so I would love to it if jaxb itself had a way of doing this automatically? Thanks, SGB

  • Skip Lists -- ever used them?

    - by Head Geek
    I'm wondering whether anyone here has ever used a skip list. It looks to have roughly the same advantages as a balanced binary tree, but is simpler to implement. If you have, did you write your own, or use a pre-written library (and if so, what was its name)?

  • Question about POP3 message termination octet

    - by user361633
    This is from the POP3 RFC. "Responses to certain commands are multi-line. In these cases, which are clearly indicated below, after sending the first line of the response and a CRLF, any additional lines are sent, each terminated by a CRLF pair. When all lines of the response have been sent, a final line is sent, consisting of a termination octet (decimal code 046, ".") and a CRLF pair. If any line of the multi-line response begins with the termination octet, the line is "byte-stuffed" by pre-pending the termination octet to that line of the response. Hence a multi-line response is terminated with the five octets "CRLF.CRLF". When examining a multi-line response, the client checks to see if the line begins with the termination octet. If so and if octets other than CRLF follow, the first octet of the line (the termination octet) is stripped away. If so and if CRLF immediately follows the termination character, then the response from the POP server is ended and the line containing ".CRLF" is not considered part of the multi-line response." Well, i have problem with this, for example gmail sometimes sends the termination octet and then in the NEXT LINE sends the CRLF pair. For example: "+OK blah blah" "blah blah." "\r\n" That's very rare, but it happens sometimes, so obviously i'm unable to determine the end of the message in such case, because i'm expecting a line that consists of '.\r\n'. Seriously, is Gmail violating the POP3 protocol or i'm doing something wrong? Also i have a second question, english is not my first language so i cannot understand that completely: "If any line of the multi-line response begins with the termination octet, the line is "byte-stuffed" by pre-pending the termination octet to that line of the response. Hence a multi-line response is terminated with the five octets "CRLF.CRLF"." When exactly CRLF.CRLF is used? Can someone gives me a simple example? The rfc says that is used when any line of the response begins with the termination octet. But i don't see any lines that starts with '.' in the messages that are terminated with CRLF.CRLF. I checked that. Maybe i don't understand something, that's why i'm asking.

  • Including Build Date strings in a C# project

    - by David Rutten
    I'd like to hard code the build date into my application (DD-mmmm-YYYY), but how do I embed this constant into the code? I thought perhaps I could make a pre-build event that executes a *.bat file that updates a textfile which is resourced, but it sounds pretty involved. What's the best approach?

  • CFPreferences for another (or all) users

    - by James Turner
    I'm working on a background service which needs to ask several users' iTunes settings (the users will opt-in via a helper application which they run from their login). Is there an easy way to read the preferences for another user, than the current one, using CFPreferences? The docs, for example for CFPreferencesCopyValue, explicitly state: 'Do not use arbitrary user and host names, instead pass the pre-defined domain qualifier constants.', when passing the 'userName' argument to the various functions.

  • Open and close trac tickets with a single commit

    - by Jerub
    I am looking for a way to add a post-commit or pre-commit hook to my VCS that will allow me to both create and close a trac ticket in one go. The use-case is for when a bug has been found, and corrected, but a single developer who wants to make sure the project manager can see the fix has been done, when it was done and what milestone the fix has been done in. We have a default milestone in trac when creating a ticket, so reflecting that information would be good too.

  • SDL_GL_SwapBuffers Segfault

    - by RyanG
    I'm getting a segfault that GDB says is coming from SDL_GL_SwapBuffers. However, I can't imagine why. The SDL documentation mentions no specific pre-conditions for calling swapBuffers except that double buffering be allowed. Is this an option I have to turn on while initializing OpenGL or is this a hardware capability thing? My code: http://pastie.org/859721 (Ignore the unused variables, strange comments and other things. I haven't prettied this up at all. :P)

  • Small Command line scripter (like Autocad commands) one line editor

    - by Objectsberg
    Basically I don't know from where to start, I need to add a line script for my application that is not so complicated, just to execute pre-defined commands, for instance: command New Invoice -- create new invoice command customer profile -- open customer form where cust id = CustID command run End-Of-Day - run the end of day process command scr 1020 -- open form id = 1020 How can I start? I have no problem of recommending any third party components (parsers,evaluators,etc..). whats missing is the basic structure no details, just a theory for implementation. Thanks, Objectberg

  • When learning C, should one only refer to resources published from 2007 onward?

    - by Adam Siddhi
    I ask this question because the international standardization subcommittee for programming languages, or ISO/IEC JTC1/SC22 Programming languages, states on this page: http://www.open-std.org/JTC1/SC22/WG14/www/standards that Technical Corrigendum 3, the latest one, was published in 2007. Now I take it that this means the C language it self was changed and that the books and tutorials pre-2007 may contain outdated information. Please correct me if I am wrong. Thanks, Adam

  • First Year Computer Science Programming Languages

    - by Jon
    I was reading this article earlier regarding C/C#/PHP being dropped as first languages in Advanced Level (pre-university) Computer Science courses: http://www.theregister.co.uk/2010/05/12/aqa_c_php/ It also goes on to say: Teachers planning to use Java are warned that many universities are considering dropping it from their first year computer science programmes, "as has happened n the US". Does anybody know, what the language predominantly used in US first year Comp Science programs is currently?

    Just like using the many twitter or facebook widgets out there that pull the feed and display it in a nice widget, I want to create a "widget" that pulls a feed from a wordpress blog that I have, and displays it on a static, non-wordpress page. Before I try getting my hands dirty with jquery, do you know if there is any pre-existing code or plugins out there that I can use?

  • Uninstall Rails 3 with dependencies?

    - by Trevor Burnham
    I like that Rails 3 is so easy to install: gem install rails --pre, and all of the dependencies are automatically installed for you. But, what about uninstalling it? If I just do gem uninstall rails, I still have actionmailer (3.0.0.beta3) actionpack (3.0.0.beta3) activemodel (3.0.0.beta3) activerecord (3.0.0.beta3) activeresource (3.0.0.beta3) activesupport (3.0.0.beta3) which I want to get rid of. What's the easiest way to do so?

    I don't want to write my own boot loader -- happy to use Grub. I just want to implement pre-emptive multi threading, a basic file system, and virtual memory. I want something that can run on top of qemu. What's a good resource (book / tutorial) for accomplishing this goal? Thanks!

  • Python: How best to parse a simple grammar?

    - by Rosarch
    Ok, so I've asked a bunch of smaller questions about this project, but I still don't have much confidence in the designs I'm coming up with, so I'm going to ask a question on a broader scale. I am parsing pre-requisite descriptions for a course catalog. The descriptions almost always follow a certain form, which makes me think I can parse most of them. From the text, I would like to generate a graph of course pre-requisite relationships. (That part will be easy, after I have parsed the data.) Some sample inputs and outputs: "CS 2110" => ("CS", 2110) # 0 "CS 2110 and INFO 3300" => [("CS", 2110), ("INFO", 3300)] # 1 "CS 2110, INFO 3300" => [("CS", 2110), ("INFO", 3300)] # 1 "CS 2110, 3300, 3140" => [("CS", 2110), ("CS", 3300), ("CS", 3140)] # 1 "CS 2110 or INFO 3300" => [[("CS", 2110)], [("INFO", 3300)]] # 2 "MATH 2210, 2230, 2310, or 2940" => [[("MATH", 2210), ("MATH", 2230), ("MATH", 2310)], [("MATH", 2940)]] # 3 If the entire description is just a course, it is output directly. If the courses are conjoined ("and"), they are all output in the same list If the course are disjoined ("or"), they are in separate lists Here, we have both "and" and "or". One caveat that makes it easier: it appears that the nesting of "and"/"or" phrases is never greater than as shown in example 3. What is the best way to do this? I started with PLY, but I couldn't figure out how to resolve the reduce/reduce conflicts. The advantage of PLY is that it's easy to manipulate what each parse rule generates: def p_course(p): 'course : DEPT_CODE COURSE_NUMBER' p[0] = (p[1], int(p[2])) With PyParse, it's less clear how to modify the output of parseString(). I was considering building upon @Alex Martelli's idea of keeping state in an object and building up the output from that, but I'm not sure exactly how that is best done. def addCourse(self, str, location, tokens): self.result.append((tokens[0][0], tokens[0][1])) def makeCourseList(self, str, location, tokens): dept = tokens[0][0] new_tokens = [(dept, tokens[0][1])] new_tokens.extend((dept, tok) for tok in tokens[1:]) self.result.append(new_tokens) For instance, to handle "or" cases: def __init__(self): self.result = [] # ... self.statement = (course_data + Optional(OR_CONJ + course_data)).setParseAction(self.disjunctionCourses) def disjunctionCourses(self, str, location, tokens): if len(tokens) == 1: return tokens print "disjunction tokens: %s" % tokens How does disjunctionCourses() know which smaller phrases to disjoin? All it gets is tokens, but what's been parsed so far is stored in result, so how can the function tell which data in result corresponds to which elements of token? I guess I could search through the tokens, then find an element of result with the same data, but that feel convoluted... What's a better way to approach this problem?
