• What initial modelling/design activities on Agile Projects do you do??

  - by dalton

  When developing an application using agile techniques, what if any initial modelling/architecture activities do you do, and how do you capture that knowledge?? I'm not after a bullet list about XP, Scrum, Crystal, DSDM..etc as I'm familiar with the methodologies. But what do you do above and beyond the guidance given by these. I find I work best by thinking the system through first, but also like the benefits of timeboxing, story cards, pairing, tdd. The closest thing I've seen so far is Scott Ambler's Initial Architecture Modelling, but was wondering what alternatives are used out there?

• how to escape white space in bash loop list

  - by MCS

  I have a bash shell script that loops through all child directories (but not files) of a certain directory. The problem is that some of the directory names contain spaces. Here are the contents of my test directory: $ls -F test Baltimore/ Cherry Hill/ Edison/ New York City/ Philadelphia/ cities.txt And the code that loops through the directories: for f in `find test/* -type d`; do echo $f done Here's the output: test/Baltimore test/Cherry Hill test/Edison test/New York City test/Philadelphia Cherry Hill and New York City are treated as 2 or 3 separate entries. I tried quoting the filenames, like so: for f in `find test/* -type d | sed -e 's/^/\"/' | sed -e 's/$/\"/'`; do echo $f done but to no avail. There's got to be a simple way to do this. Any ideas? The answers below are great. But to make this more complicated - I don't always want to use the directories listed in my test directory. Sometimes I want to pass in the directory names as command-line parameters instead. I took Charles' suggestion of setting the IFS and came up with the following: dirlist="${@}" ( [[ -z "$dirlist" ]] && dirlist=`find test -mindepth 1 -type d` && IFS=$'\n' for d in $dirlist; do echo $d done ) and this works just fine unless there are spaces in the command line arguments (even if those arguments are quoted). For example, calling the script like this: test.sh "Cherry Hill" "New York City" produces the following output: Cherry Hill New York City Again, I know there must be a way to do this - I just don't know what it is...

• using wget against protected site with NTLM

  Trying to mirror a local intranet site and have found previous questions using 'wget'. It works great with sites that are anonymous, but I have not been able to use it against a site that is expecting username\password (IIS with Integrated Windows Authentication).

• Relative Uri works for BitmapImage, but not for MediaPlayer?

  - by Thomas Stock

  This will be simple for you guys: var uri = new Uri("pack://application:,,,/LiftExperiment;component/pics/outside/elevator.jpg"); imageBitmap = new BitmapImage(); imageBitmap.BeginInit(); imageBitmap.UriSource = uri; imageBitmap.EndInit(); image.Source = imageBitmap; = Works perfectly on a .jpg with Build Action: Content Copy to Output Directory: Copy always MediaPlayer mp = new MediaPlayer(); var uri = new Uri("pack://application:,,,/LiftExperiment;component/sounds/DialingTone.wav"); mp.Open(uri); mp.Play(); = Does not work on a .wav with the same build action and copy to output. I see the file in my /debug/ folder.. MediaPlayer mp = new MediaPlayer(); var uri = new Uri(@"E:\projects\LiftExp\_solution\LiftExperiment\bin\Debug\sounds\DialingTone.wav"); mp.Open(uri); mp.Play(); = Works perfectly.. So, how do I get the sound to work with a relative path? Why is it not working this way? Let me know if you want more code or screenshots. Thanks.

• UITextView text disappear

  - by user153412

  Hi, i create an uitextview dynamically then i write my text into it. Sometime, when i create the uitextview, the cursor disappear and i see no text in it. If i run the application again, i can see the text inside the textview that i've created before. I've tried to set the cursor position to zero or scroll the text to the top but it doesn't work... Any suggestion? Here is a screen capture. You can see the gray uitextview, the keyboard (the textview is the firstresponder) but no cursor or text. http://yfrog.com/hqschermata20100325a11213p PS: i'm sorry for my bad english.

• Jquery and XML - How to add the value of nodes

  - by Matias

  Hi Experts, This may be a simple question though can´t figure out how to do it. I am parsing an XML with Jquery Ajax. It contains dates and rates The XML looks something like <rate> <date>Today</date> <price>66</price> </rate> <rate> <date>Tomorrow</date> <price>99</price> </rate> I simply want to figure out how to calculate the total price of both days Today and Tomorrow. Thought that by using Javascript Number it will simply return the total value of the nodes.. $(xml).find("rate").each(function() { $(this).find("price").each(function() { $("#TOTALPRICE").append(Number($(this).text())); } } //output is: 6699 However, it´s just concatenating the values both not adding them. //output is: 6699 I greatly appreciate your help !! Thanks

• C++ Exceptions and Inheritance from std::exception

  - by fbrereto

  Given this sample code: #include <iostream> #include <stdexcept> class my_exception_t : std::exception { public: explicit my_exception_t() { } virtual const char* what() const throw() { return "Hello, world!"; } }; int main() { try { throw my_exception_t(); } catch (const std::exception& error) { std::cerr << "Exception: " << error.what() << std::endl; } catch (...) { std::cerr << "Exception: unknown" << std::endl; } return 0; } I get the following output: Exception: unknown Yet simply making the inheritance of my_exception_t from std::exception public, I get the following output: Exception: Hello, world! Could someone please explain to me why the type of inheritance matters in this case? Bonus points for a reference in the standard.

• Strange xml/html accent issue

  - by Ayrad

  I have an XML file that contains a message with html tags in it. The XML file is read by a java class that mails it to people. When the mail is received, the accents do not show. For example é doesn't show. I have tried &eacute; in the xml but it gives an error in eclipse saying that the entity has not been declared. I also tried simply inserting &#233; but that shows nothing in the final output. The 3rd thing I tried was using <![CDATA[é]]> but that broke the parser since it didn't output anything after it. However I noticed something weird. When i put something like this in the xml and added UTF-16 encoding <message>text bla bla blaa é&lt; it did ouput the é at the end like this bla bla blaa blaa é. EDIT <message>text bla bla blaa éé&lt; outputs ?é or just one é The file looks something like this: <?xml version="1.0"? encoding="UTF-16"> <message> &lt;b&gt;hello é &lt;/b&gt; </message> </xml> What gives?

• How to write a C program using the fork() system call that generates the Fibonacci sequence in the

  - by Ellen

  The problem I am having is that when say for instance the user enters 7, then the display shows: 0 11 2 3 5 8 13 21 child ends. I cannot seem to figure out how to fix the 11 and why is it displaying that many numbers in the sequence! Can anyone help? The number of the sequence will be provided in the command line. For example, if 5 is provided, the first five numbers in the Fibonacci sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a non-negative number is passed on the command line. #include <stdio.h> #include <sys/types.h> #include <unistd.h> int main() { int a=0, b=1, n=a+b,i,ii; pid_t pid; printf("Enter the number of a Fibonacci Sequence:\n"); scanf("%d", &ii); if (ii < 0) printf("Please enter a non-negative integer!\n"); else { pid = fork(); if (pid == 0) { printf("Child is producing the Fibonacci Sequence...\n"); printf("%d %d",a,b); for (i=0;i<ii;i++) { n=a+b; printf("%d ", n); a=b; b=n; } printf("Child ends\n"); } else { printf("Parent is waiting for child to complete...\n"); wait(NULL); printf("Parent ends\n"); } } return 0; }

• Gallio MbUnit and Team City problem

  - by Bernard Larouche

  I asked a question this morning about an integration problem between Gallio and Team City. I changed the msbuild file to use the proper syntax with the latest Gallio build script API.

• File permissions with FileSystemObject - CScript.exe says one thing, Classic ASP says another...

  - by Dylan Beattie

  I have a classic ASP page - written in JScript - that's using Scripting.FileSystemObject to save files to a network share - and it's not working. ("Permission denied") The ASP page is running under IIS using Windows authentication, with impersonation enabled. If I run the following block of code locally via CScript.exe: var objNet = new ActiveXObject("WScript.Network"); WScript.Echo(objNet.ComputerName); WScript.Echo(objNet.UserName); WScript.Echo(objNet.UserDomain); var fso = new ActiveXObject("Scripting.FileSystemObject"); var path = "\\\\myserver\\my_share\\some_path"; if (fso.FolderExists(path)) { WScript.Echo("Yes"); } else { WScript.Echo("No"); } I get the (expected) output: MY_COMPUTER dylan.beattie MYDOMAIN Yes If I run the same code as part of a .ASP page, substituting Response.Write for WScript.Echo I get this output: MY_COMPUTER dylan.beattie MYDOMAIN No Now - my understanding is that the WScript.Network object will retrieve the current security credentials of the thread that's actually running the code. If this is correct - then why is the same user, on the same domain, getting different results from CScript.exe vs ASP? If my ASP code is running as dylan.beattie, then why can't I see the network share? And if it's not running as dylan.beattie, why does WScript.Network think it is?

• Display Image from Byte Array in WPF - Memory Issues

  - by ChrisFletcher

  Hi, I've developed an application to capture and save images to a database, but I'm having an issue with memory usage. On my domain object I have 3 properties: Image - Byte array, contents are a jpg RealImageThumb - The byte array converted to a BitmapImage and shrunk, displayed to the user in a gridview with other thumbnails RealImage - Has no setter, the byte array converted to a bitmap source, this is shown in a tooltip when the user hovers over it. The issue I have is that if a user hovers over each image in turn the memory usage spirals. I realise that as a user hovers over bitmap sources are generated and the memory isn't freed up, I've tried giving RealImage a backing property and assigning this to null after but again the memory isn't freed up (waiting for the garbage colelctor?.

• Regex for capturing numbered text list

  - by crunchyt

  I have a test list that I am trying to capture data from using a regex. Here is a sample of the text format: (1) this is a sample string /(2) something strange /(3) another bit of text /(4) the last one/ something!/ I have a Regex that currently captures this correctly, but I am having some difficulty with making it work under outlier conditions. Here is my regex /\(?\d\d?\)([^\)]+)(\/|\z)/ Unfortunately some of the data contains parentheses like this: (1) this is a sample string (1998-1999) /(2) something strange (blah) /(3) another bit of text /(4) the last one/ something!/ The substrings '(1998-1999)' and '(blah)' make it fail! Anyone care to have a crack at this one? Thank you :D

• Is there a way to use the transactions in TCPDF when extending it with FPDI?

  - by Darryl Hein

  I am using TCPDF with FPDI's bridge. The issue I'm having is that as soon as I use the startTransaction() I get the following error: TCPDF ERROR: Cannot access protected property FPDI:$numpages / Undefined property: FPDI::$numpages and the script ends (because of the die in the TCPDF::Error() method). Here is the code I'm using: $pdf = new FPDI(); // add a page $pdf->AddPage(); $pdf->startTransaction(); $pdf->Cell(0, 0, 'blah blah blah'); $pdf->rollbackTransaction(); $pdf->Output( . time() . '.pdf', 'D'); If I change it to: $pdf = new FPDI(); // add a page $pdf->AddPage(); $pdf->Cell(0, 0, 'blah blah blah'); $pdf->Output( . time() . '.pdf', 'D'); it works fine. Is there anyway to make them work together and use TCPDF's transactions?

• How to add an image when generating a pdf-file with javascript. When adding the imageLoadFromURL no pdf is generated

  - by Angu Handschuh

  I've got a problem with adding an image when generating a pdf-file with javascript. Here is my code: <!DOCTYPE html> <html> <head> <script type="text/javascript" src="base64.js"></script> <script type="text/javascript" src="sprintf.js"></script> <script type="text/javascript" src="jspdf.js"></script> <script> function demo1() { var name = prompt('Name: '); var nachname=prompt('Nachname: '); var doc = new jsPDF(); doc.setFontSize(22); doc.text(20, 20, 'Der eingegebene Text'); doc.setFontSize(16); doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); doc.text(20, 30, 'Name: ' + name); doc.text(20,40,'Nachname:'+nachname); // Output as Data URI doc.output('datauri'); } </script> </head> <body> <h2> Ein Document </h2> <a href="javascript:demo1()"> PDF erstellen </a> </body> </html> Before adding doc.imageLoadFromUrl('image.jpg'); doc.imagePlace(20, 40); the code runs without picture. It starts with a demand note for the name and the second name, after this it generates a pdf-file. But when adding the imageLoad-Method there is no pdf-file generated. Does anyone konws how to solve this problem?

• Code Golf: Tic Tac Toe

  - by Aistina

  Post your shortest code, by character count, to check if a player has won, and if so, which. Assume you have an integer array in a variable b (board), which holds the Tic Tac Toe board, and the moves of the players where: 0 = nothing set 1 = player 1 (X) 2 = player 2 (O) So, given the array b = [ 1, 2, 1, 0, 1, 2, 1, 0, 2 ] would represent the board X|O|X -+-+- |X|O -+-+- X| |O For that situation, your code should output 1 to indicate player 1 has won. If no-one has won you can output 0 or false. My own (Ruby) solution will be up soon. Edit: Sorry, forgot to mark it as community wiki. You can assume the input is well formed and does not have to be error checked. Update: Please post your solution in the form of a function. Most people have done this already, but some haven't, which isn't entirely fair. The board is supplied to your function as the parameter. The result should be returned by the function. The function can have a name of your choosing.

• emacs tramp performance

  - by Oleg Pavliv

  Is there a way to improve emacs tramp performance? For me it's faster to open an external ftp client (filezilla), transfer files to the local disk and open them in an external editor (notepad) than open them with emacs. I use emacs23.1 under windows xp. I tried different tramp-default-method (telnet, pscp, ftp), all of them have the same performance. Profiling results with elp-instrument-package are the following (I opened 3 remote files of 1.5 MB each one) tramp-file-name-handler 1461 350.41599999 0.2398466803 tramp-sh-file-name-handler 1461 350.02699999 0.2395804243 tramp-send-command 227 179.63400000 0.7913392070 tramp-send-command-and-check 205 177.77600000 0.8672000000 tramp-wait-for-regexp 227 176.47800000 0.7774361233 tramp-wait-for-output 226 176.40000000 0.7805309734 tramp-barf-unless-okay 18 133.46699999 7.4148333333 tramp-handle-insert-file-contents 3 132.046 44.015333333 tramp-handle-file-local-copy 3 131.281 43.760333333 tramp-accept-process-output 2375 112.95100000 0.0475583157 So, actual file transfer takes 132 sec, about 1/3 of total time. Why does it spend so much time in tramp-sh-file-name-handler? I tried to advice a function tramp-sh-file-name-handler to store and return cached results but it does not work, probably this function has some side effects. Any ideas how to improve tramp performance? (I use emacs 23.1 under WindowsXP)

• How to replace openSSL calls with C# code?

  - by fonix232

  Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python. I don't know neither language too much (had some basic experience in Python though, but mostly with PyS60), so I would like to ask you to help me convert this python app to a C# code that doesn't depend on external programs. Also, here is the source of crxmake.py: #!/usr/bin/python # Cribbed from http://github.com/Constellation/crxmake/blob/master/lib/crxmake.rb # and http://src.chromium.org/viewvc/chrome/trunk/src/chrome/tools/extensions/chromium_extension.py?revision=14872&content-type=text/plain&pathrev=14872 # from: http://grack.com/blog/2009/11/09/packing-chrome-extensions-in-python/ import sys from array import * from subprocess import * import os import tempfile def main(argv): arg0,dir,key,output = argv # zip up the directory input = dir + ".zip" if not os.path.exists(input): os.system("cd %(dir)s; zip -r ../%(input)s . -x '.svn/*'" % locals()) else: print "'%s' already exists using it" % input # Sign the zip file with the private key in PEM format signature = Popen(["openssl", "sha1", "-sign", key, input], stdout=PIPE).stdout.read(); # Convert the PEM key to DER (and extract the public form) for inclusion in the CRX header derkey = Popen(["openssl", "rsa", "-pubout", "-inform", "PEM", "-outform", "DER", "-in", key], stdout=PIPE).stdout.read(); out=open(output, "wb"); out.write("Cr24") # Extension file magic number header = array("l"); header.append(2); # Version 2 header.append(len(derkey)); header.append(len(signature)); header.tofile(out); out.write(derkey) out.write(signature) out.write(open(input).read()) os.unlink(input) print "Done." if __name__ == '__main__': main(sys.argv) Please could you help me?

  I'm checking into upgrading to VS2010. Our production servers only have 3.5 Framework and it will be 6-9 months before they are updated. We also have a Continuous Integration Server, running CruiseControl.NET (CC.NET). It has the 3.5 Framework on it as well. Our implementation of CC.NET mainly calls msbuild.exe MySolution.msbuild. (We encapsulate most of the build logic into .msbuild files fyi) Inside the .msbuild file, the following is the "Build" syntax: < Target Name="Build" DependsOnTargets="Checkout" < MSBuild Projects="$(WorkingCheckout)\MySolution.sln" Targets="Build" Properties="Configuration=$(Configuration)" < Output TaskParameter="TargetOutputs" ItemName="TargetOutputsItemName"< /Output < /MSBuild < /Target (A few spaces added to make it display here) =========== I know the VS2010 can "Target" the 3.5 Framework. My question is what happens when I have a VS2010 dev machine, and I check the VS2010 .sln and .csproj(s) files into source control (svn, btw).....will the CC.NET machine ~~which only have the 3.5 Framework installed on it........be able to build the .sln ? I guess I could test it, but the catch22 is that I don't have VS2010 (yet). So I'm asking before I try (the trial or a real install. ............. Any ideas what will happen? I guess the crux question is, what will happen. c:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe "MyVS2010SolutionFile.sln" ?? My hopeful goal would be, allow the developers to have VS2010 (now!), and it still be "ok" for the CC.NET machine and the Production Servers which will only have the 3.5 Framework on them for the foreseeable future. Just to be clear, developers NEVER create deployable builds. Only the CC.NET machine produces builds that will be pushed as production builds. Any help?

• configure batch to sent minute info instead of entire stdout

  - by Daniel

  Hi all, I am working on a RedHat server along with several other users. We use the batch utility to set a job queue. Some of the programs that I use write stuff to stdout during the run, with info on who much data has been processed to far and estimated time until completion etc. batch -q z at> myScript -i somefile -o someotherfile By default, the batch util send an email to me (since I configured it using .forward) with the entire output from stdout. Since the scripts writes something to stdout a few times each second, the amount of log-stuff I get from a two-day script can be ˜20 Mbs. Clearly not what I want. I can of course pipe stdout to a file like so batch -q z at> myScript -i somefile -o someotherfile > myscript.stdout.log but then I get a blank e-mail from the util. So to my question: Is it possible to configure batch so that it sends time the job started and ended, or run time or some oth valuable information to me, instead of a 20 Mb mail or a blank mail? Note that the scripts that I use are binaries and I cannot customize the code to output less info in the first place (which would be the optimal solution I guess). Thanks /Daniel

• IIS7 Custom Errror Handling Troubles for Classic ASP Website

  - by Eaphis

  I recently upgraded a web server from IIS6 to IIS7 for a classic asp application and now experience a bizarre error. In the IIS6 set up there was a custom 500-100 page that functioned properly by capturing errors and delivering an email with error code, error source and error type values. That same structure was set up on the IIS7 machine but now the error emails contain no error information at all. They all come through values such as 'NO SPECIFIC ERROR CODE', 'NO SPECIFIC ERROR DESCRIPTION', 'NO SPECIFIC ERROR SOURCE'. Any one have some thoughts on why my custom error page cannot capture the error information?
