• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• Emailing smtp with Python error

  - by jakecar

  I can't figure out why this isn't working. I'm trying to send an email from my school email address with this code I got online. The same code works for sending from my GMail address. Does anyone know what this error means? The error occurs after waiting for about one and a half minutes. import smtplib FROMADDR = "FROM_EMAIL" LOGIN = "USERNAME" PASSWORD = "PASSWORD" TOADDRS = ["TO_EMAIL"] SUBJECT = "Test" msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (FROMADDR, ", ".join(TOADDRS), SUBJECT) ) msg += "some text\r\n" server = smtplib.SMTP('OUTGOING_SMTP', 587) server.set_debuglevel(1) server.ehlo() server.starttls() server.login(LOGIN, PASSWORD) server.sendmail(FROMADDR, TOADDRS, msg) server.quit() And here's the error I get: Traceback (most recent call last): File "emailer.py", line 13, in server = smtplib.SMTP('OUTGOING_SMTP', 587) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 239, in init (code, msg) = self.connect(host, port) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 295, in connect self.sock = self._get_socket(host, port, self.timeout) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/smtplib.py", line 273, in _get_socket return socket.create_connection((port, host), timeout) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/socket.py", line 514, in create_connection raise error, msg socket.error: [Errno 60] Operation timed out

• Why aren't google api clients built on top of Apache's Abdera project ?

  - by lisak

  Hey, Could anybody please explain that to me? As far as I can see, the developers of java's google api client library are reinventing the wheel. It's like writing a new JDK for a Java project. I'm aware of the fact that google data protocol is a little specific re atom publishing, but if one needs to use some of the fancy extensions and features that Apache Abdera project offers for this protocol, it is better not to use google api client library and implement the client from scratch with Abdera... And I'm sure that in a lot of cases its features such as Abdera's JCR adapter would become very handy for google docs, google translator toolkit and others. Now it's great that there is a google api client library to be used for google docs, but what am I going to do with the documents? I believe that in more than a half cases there is also a repository or database on the other side. And in that case, abdera is needed, not the simple google api clients that are only marshalling/unmarshalling the feeds... In fact, there is something to persist in all of the google APIs. It would make sense, if google decided to invest the effort into Abdera enhancement... This doesn't... Also for the question to be more specific: How are you developing google api clients, that need entry persistence (JCR for instance) ? What would be the best way to integrate a google api client library with Apache Abdera ?

• Eclipse Maven web application - can not run on server anymore

  I have an maven eclipse webapp project that I was able to right click and 'Run on server' and it would deploy on tomcat.

  - by satyam

  I've simple iphone application. it has 3 views. first view is portrait view that has 3 buttons. second view has a table view which is also a portrait. In first view, on click of a button second view is shown. on click of a cell in second view, thrid view is shown. but third view is a landscape. I'm using "pushViewController" to navigate from each view. When creating views in IB, first two views are portait and 3rd view is a landscape. In 3rd viewcontroller, i'm using following code as well: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { //return UIInterfaceOrientationIsLandscape(interfaceOrientation); return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)); } How can I show first two views in portrait and third view in landscape.

• Cocoa App with Python extension which use Scipy -> ImportError: No module named scipy

  - by Snej

  Hi: I have installed Scipy (via macports) for Python on my Mac and it runs fine when running Python scripts. But now I'm using Scipy (via PyObjc) for calculations embedded in a Cocoa App frontend. The following error occurs: ImportError: No module named scipy I am using the "Python.framework" in XCode. Does anybody know why Scipy module is not found? I even added it manually to the module search path via sys.path.append("/opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/") EDIT: I found the problem myself. The path should be without "/scipy" at the end. But now I got an architecture problem: ImportError: dlopen(/opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/fftpack/_fftpack.so, 2): no suitable image found.

• About Data Objects and DAO Design when using Hibernate

  - by X. Ma

  I'm hesitating between two designs of a database project using Hibernate. Design #1. (1) Create a general data provider interface, including a set of DAO interfaces and general data container classes. It hides the underneath implementation. A data provider implementation could access data in database, or an XML file, or a service, or something else. The user of a data provider does not to know about it. (2) Create a database library with Hibernate. This library implements the data provider interface in (1). The bad thing about Design #1 is that in order to hide the implementation details, I need to create two sets of data container classes. One in the general data provider interface - let's call them DPI-Objects, the other set is used in the database library, exclusively for entity/attribute mapping in Hibernate - let's call them H-Objects. In the DAO implementation, I need to read data from database to create H-Objects (via Hibernate) and then convert H-Objects into DPI-Objects. Design #2. Do not create a general data provider interface. Expose H-Objects directly to components that use the database lib. So the user of the database library needs to be aware of Hibernate. I like design #1 more, but I don't want to create two sets of data container classes. Is that the right way to hide H-Objects and other Hibernate implementation details from the user who uses the database-based data provider? Are there any drawbacks of Design #2? I will not implement other data provider in the new future, so should I just forget about the data provider interface and use Design #2? What do you think about this? Thanks for your time!

• Creating an installer with WPF forms, packaged files and custom setup actions in C#

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• inherit properties and then change some on particular site (css)

  - by Radek

  I have three menus on this test web site. I am learning css and trying all the menus inherit all properties from menu class. The second one looks different and is not clickable. I am happy with the 3rd one, just want to make it horizontal and change its position bit. Could somebody tell me why the second menu is not click-able? how I can make the third menu vertical? I thought that display: block; for li of the 3rd menu would do the trick but I do not know the css path for that li.

• Shibboleth + IIS and Pound Reverse Proxy

  - by boburob

  Having a bit of a problem getting Shibboleth (SSO) working with ADFS and Pound. The main problem seems to be that: The website address will be https://website.domain.com Pound will then terminate the SSL and forward the traffic to the webserver on a different port (http://server.domain.com:8888) I have set up Shibboleth to protect the address http://server.domain.com:8888, which allows me to retrieve metadata and it all seems to be working fine. However the problem seems to be that ADFS is configured to protect the https website, so when Shibboleth attempts to recieve information from ADFS I get nothing except the following error: A token request was received for a relying party identified by the key 'https://msstagrevproxy.cwpintranet.com/shibboleth', but the request could not be fulfilled because the key does not identify any known relying party trust. Key: https://msstagrevproxy.cwpintranet.com/shibboleth I am not really sure how I can work around this as to retrieve the metadata from Shibboleth I have to use the https address but this does not actually exist in Shibboleth or IIS. Has anyone had any experience with this before or using any other SSO with a reverse proxy that works?

• How to override the default init.tcl

  - by Sean Murphy

  I'm working on a project where I want to make use of TCL as the command interpreter. I have a working c library object which I can load from within the tcl shell but my problem is finding a way to automatically do this while starting a tclsh. Essentially my ultimate goal is to be able to run a script and have it load my library and run some initial startup tcl code before dropping me back to the tclsh command prompt in interactive mode. e.g. tclsh -f myscript.tcl --then-switch-to-interactive or EXPORT TCLINIT=myscript.tcl tclsh The basic goal is to avoid having to distribute tclsh but rather rely in local user installations of tcl. All I would like to distribute is my library, a startup script and a shell command to launch the tclsh with the library preloaded. I've tried using the environment variables TCLINIT and TCL_LIBRARY but they seem to have no effect. The only workable solutions I've found so far are to add "source myscript.tcl" to either the end of /usr/share/tcltk/tcl8.5.init.tcl or ~/.tclshrc However both of these "solutions" are non perfect as they require modification of the default users workspace. It strikes me that there must be a way to handle this in TCL, but my research so far hasn't yielded anything. Does anyone have any suggestions?

• jquery ajax post callback - manipulation stops after the "third" call

  - by shanyu

  EDIT: The problem is not related to Boxy, I've run into the same issue when I've used JQuery 's load method. EDIT 2: When I take out link.remove() from inside the ajax callback and place it before ajax load, the problem is no more. Are there restrictions for manipulating elements inside an ajax callback function. I am using JQuery with Boxy plugin. When the 'Flag' link on the page is clicked, a Boxy modal pops-up and loads a form via ajax. When the user submits the form, the link (<a> tag) is removed and a new one is created from the ajax response. This mechanism works for, well, 3 times! After the 3rd, the callback function just does not remove/replace/append (tested several variations of manipulation) the element. The only hint I have is that after the 3rd call, the parent of the link becomes non-selectable. However I can't make anything of this. Sorry if this is a very trivial issue, I have no experience in client-side programming. The relevant html is below: <div class="flag-link"> <img class="flag-img" style="width: 16px; visibility: hidden;" src="/static/images/flag.png" alt=""/> <a class="unflagged" href="/i/flag/showform/9/1/?next=/users/1/ozgurisil">Flag</a> </div> Here is the relevant js code: $(document).ready(function() { $('div.flag-link a.unflagged').live('click', function(e){ doFlag(e); return false; }); ... }); function doFlag(e) { var link = $(e.target); var url = link.attr('href'); Boxy.load(url, {title:'Inappropriate Content', unloadOnHide:true, cache:false, behaviours: function(r) { $("#flag-form").live("submit", function(){ var post_url = $("#flag-form").attr('action'); boxy = Boxy.get(this); boxy.hideAndUnload(); $.post(post_url, $("#flag-form").serialize(), function(data){ par = link.parent(); par.append(data); alert (par.attr('class')); //BECOMES UNDEFINED AT THE 3RD CALL!! par.children('img.flag-img').css('visibility', 'visible'); link.remove(); }); return false; }); }}); }

• Convert Form to UserControl

  - by Joe

  I have a 3rd party code library that I'm using; part of this library is a winforms application for editing the configuration files used by this library. I would like to embed their configuration editor app into my application. I have the source code to their library and the configuration editor is (as far as I can tell) a straight forward Winforms app using standard controls. I'm trying to convert the app's main form into a UserControl so that I can host it inside my application which is WPF (WPF's WindowsFormsHost won't host a Form object, I get an exception). I changed the form object to inherit from UserControl instead of Form and fixed all the compiler errors (there weren't many, just property initializations that don't exist on UserControls) but what's happening is my newly converted control is just blank. When I run my test app I don't see any of the controls that make up the original form, just a blank page. Any ideas? I really don't want to have to re-implement their app from scratch, that would suck. Edit: I forgot to mention I'm testing this in a WinForms application, not WPF, to just get the control working before trying to use it from WPF.

• Python import error: Symbol not found, but the symbol <s>is</s> *is not* present in the file

• Monitoring outgoing internet traffic

  - by Frane

  Is there a way to monitoring internet traffic programatically? I would like to log the pages users are visiting on the Internet. Can this be achieved with .NET code, is there a 3rd party .NET component that could be used to retrieved data. Information about Internet traffic must be stored to a database so I cannot use a plugin or something for IE. We are also looking to include this code into our existing product so we cannot use a 3rd party product that cannot be redistributed. It would be cool if this thing could monitor traffic for all browsers but monitoring IE traffic might also be sufficient.

• .NET interop COM DLL behaves differently in VB6 debugger

  - by Aheho

  I have a .NET v2.0 Dll that exposes a few classes to COM. The assembly is called BLogic.DLL I'm calling these classes from a legacy visual basic 6.0 application. I can generate and EXE file and if I have Blogic.dll in the same folder as the EXE, the program runs without a hitch. However If I try and launch the same program within the VB6 debugger I get a: Automation Error The system cannot find the file specified I assume when I'm running in the debugger, the PLogic.dll file can't be found. I tried putting it in the System32 folder, and the same folder as the VB6.EXE file, but I still get the same error. Other facts that may help: PLogic.dll is NOT a strongly-named assembly. It depends on a 3rd party reference that isn't strongly signed so VS doesn't let me strongly sign it. However the 3rd party functionality isn't being called by the VB6 code, and it is not ComVisible.

• How to Use 3 Monitors

  - by The.Anti.9

  Right now my setup has a nice big 24" flatscreen in the center, and a 19" flatscreen to the left. And a big gaping hole on the right. I have a 3rd monitor to put there, but I'm not sure how to get the computer to recognize it. Do I need a graphics card with 3 ports? Or can I span the monitors over non SLI-Linked graphics cards? Is it possible to plug my 3rd monitor into the on-board VGA port and have it work?

• Can I version dotfiles within a project without merging their history into the main line?

  - by istrasci

  I'm sure this title is fairly obscure. I'm wondering if there is some way in git to tell it that you want a certain file to use different versions of a file when moving between branches, but to overall be .gitignored from the repository. Here's my scenario: I've got a Flash Builder project (for a Flex app) that I control with git. Flex apps in Flash Builder projects create three files: .actionScriptProperties, .flexProperties, and .project. These files contain lots of local file system references (source folders, output folders, etc.), so naturally we .gitignore them from our repo. Today, I wanted to use a new library in my project, so I made a separate git branch called lib, removed the old version of the library and put in the new one. Unfortunately, this Flex library information gets stored in one of those three dot files (not sure which offhand). So when I had to switch back to the first branch (master) earlier, I was getting compile errors because master was now linked to the new library (which basically negated why I made lib in the first place). So I'm wondering if there's any way for me to continue to .gitignore these files (so my other developers don't get them), but tell git that I want it to use some kind of local "branch version" so I can locally use different versions of the files for different branches.

• can the python wave module accept StringIO object

  - by user368005

  i'm trying to use the wave module to read wav files in python. whats not typical of my applications is that I'm NOT using a file or a filename to read the wav file, but instead i have the wav file in a buffer. And here's what i'm doing import StringIO buffer = StringIO.StringIO() buffer.output(wav_buffer) file = wave.open(buffer, 'r') but i'm getting a EOFError when i run it... File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/wave.py", line 493, in open return Wave_read(f) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/wave.py", line 163, in __init__ self.initfp(f) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/wave.py", line 128, in initfp self._file = Chunk(file, bigendian = 0) File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/chunk.py", line 63, in __init__ raise EOFError i know the StringIO stuff works for creation of wav file and i tried the following and it works import StringIO buffer = StringIO.StringIO() audio_out = wave.open(buffer, 'w') audio_out.setframerate(m.getRate()) audio_out.setsampwidth(2) audio_out.setcomptype('NONE', 'not compressed') audio_out.setnchannels(1) audio_out.writeframes(raw_audio) audio_out.close() buffer.flush() # these lines do not work... # buffer.output(wav_buffer) # file = wave.open(buffer, 'r') # this file plays out fine in VLC file = open(FILE_NAME + ".wav", 'w') file.write(buffer.getvalue()) file.close() buffer.close()

• BeautifulSoup HTMLParseError. What's wrong with this?

  - by user1915496

  This is my code: from bs4 import BeautifulSoup as BS import urllib2 url = "http://services.runescape.com/m=news/recruit-a-friend-for-free-membership-and-xp" res = urllib2.urlopen(url) soup = BS(res.read()) other_content = soup.find_all('div',{'class':'Content'})[0] print other_content Yet an error comes up: /Library/Python/2.7/site-packages/bs4/builder/_htmlparser.py:149: RuntimeWarning: Python's built-in HTMLParser cannot parse the given document. This is not a bug in Beautiful Soup. The best solution is to install an external parser (lxml or html5lib), and use Beautiful Soup with that parser.

• AJAX Autosave

  - by antony.trupe

  What's the best javascript library, or plugin or extension to a library, that has implemented autosaving functionality? The specific need is to be able to 'save' a data grid. Think gmail and Google Documents' autosave. I don't want to reinvent the wheel if its already been invented. I'm looking for an existing implementation of the magical autoSave() function. Auto-Saving:pushing to server code that saves to persistent storage, usually a DB. The server code framework is outside the scope of this question. Note that I'm not looking for an Ajax library, but a library/framework a level higher: interacts with the form itself. daemach introduced an implementation on top of jQuery @ http://ideamill.synaptrixgroup.com/?p=3. I'm not convinced it meets the lightweight and well engineered criteria though. Criteria stable, lightweight, well engineered saves onChange and/or onBlur saves no more frequently then a given number of milliseconds handles multiple updates happening at the same time doesn't save if no change has occurred since last save saves to different urls per input class Updates I've stabilized a solution. See my answer below for links.

• Tunneling HTTP traffic from a particular host/port

  - by knoopx

  Hello, I'm trying to figure out how to access from my development machine (Devel) to a third party web service (www.domain.com) which I am not allowed to directly contact using my office IP address. Here's a basic diagram (i'm not allowed to post images...): http://yuml.me/diagram/scruffy/class/%5BDevel%5D-%5BA%5D,%20%5BA%5D-%5BB%5D,%20%5BB%5D-%5Bwww.domain.com%5D The only machine allowed to access that service is B (production server) but I do neither can directly access it from my development machine (Devel). So in order to access the web service I have to ssh into A, and then from A to B to access www.domain.com Is there any way of tunneling traffic from B to A and then back to my development machine so I can directly access www.domain.com without having to ssh into every box? Devel: My development machine. A, B: Linux servers. I own root access on both. B: Production server www.domain.com: Third party HTTP API production server uses.
