    - by Ram Bhat
    Hey guys, Lets say you have a grid like this (made randomly) Now lets say you have a car starting randomly from one of the while boxes, what would be the shortest path to go through each one of the white boxes? you can visit each white box as many times as you want and cant Jump over the black boxes. The black boxes are like walls. In simple words you can move from white box to white box only.. You can move in any direction, even diagonally.

  • What's the primary use of Windows Event Viewer?

    - by james.ingham
    Hi all, Just wondering what everybody's opinion is on the Windows Admin tool Event Viewer? I'm writing a WCF application at the moment and have started logging errors to the windows event viewer when I handle them. I then started thinking, should I be logging more than just errors, such as when a user has logged in or out or would you go further logging even more activity? Or is this a tool that's mainly used for testing without using the debugger? Any input appreciated:-)

  • How do I retrieve program output in Python?

    - by Geoff
    I'm not a Perl user, but from this question deduced that it's exceedingly easy to retrieve the standard output of a program executed through a Perl script using something akin to: $version = `java -version`; How would I go about getting the same end result in Python? Does the above line retrieve standard error (equivalent to C++ std::cerr) and standard log (std::clog) output as well? If not, how can I retrieve those output streams as well? Thanks, Geoff

  • XCode project compiling

    - by n179911
    Hi, I get the chromium source and I am able to compile it fine under MaxOS X. My question is why every time I power off my laptop and then re-open my XCode project and click 'Build and Go (Debug)', XCode recompiles EVERYTHING (even I have not modified any file). Is there any way to config to compile when needed? Thank you for any suggestion.

  • Usage of open source libraries in high governance and risk-averse large organizations (banks, financ

    - by bart
    Does anyone have any good stories of these kinds of organizations being open to using open source dependencies (and also tools). Many staff I've encountered have little or no exposure to open source/systems and open source is treated with great suspicion. Some reasons given for this are lack of support and robustness, which is ironic given the number of end-of-life unsupported vendor products that are in production. I'm also interested in any success stories where you've seen open source go into orgs like this and have a real benefit!

  • urllib2 in Python 2.6.4: Any way to override windows hosts file?

    - by mikez302
    I am using the urllib2 module in Python 2.6.4, running in Windows XP, to access a URL. I am making a post request, that does not involve cookies or https or anything too complicated. The domain is redirected in my C:\WINDOWS\system32\drivers\etc\hosts file. However, I would like the request from urllib2 to go to the "real" domain and ignore the entry in the hosts file. Is there any easy and practical way to do this?

  • FTP files in Windows Scripting Host?

    - by adib
    Hi What is the recommended way to transfer files via FTP and manage (rename, move, delete) files in an FTP server programmatically in a Windows Scripting Host script file (JavaScript/VBScript)? Preferably without requiring 3rd party ActiveX add-ons since these "extra" software will need to go through an approval process that will take a very long time, even for free (as in beer) and/or open source components. The script is going to be run in a Windows 2003 Server in data center environment. Thanks.

  • Can't remember the website for downloading common tools after reinstall

    - by JB
    I remember a while back finding a website for downloading lots of common tools in one go after a system reinstall. It had a dark background and checkboxes for selecting the tools (browsers, editors, readers, im clients, etc.). After selecting the tools it downloaded a file which went away, downloaded everything you'd selected and then performed an install on each of the different apps. Does anyone have any idea what I'm talking about?

  • How does ruby's rb_raise stop the execution of the c function calling it?

    - by Adrian
    If you write a ruby method as a function in C that uses rb_raise, the part of the function after the call will not get excecuted and the program will stop and you will think that rb_raise used exit(). But if you rescue the exception in ruby, like: begin method_that_raises_an_exception rescue end puts 'You wil still get here.' The ruby code will go on, but your function will stop excecuting. How does rb_raise make this happen?

  • How to create a "Clustergram" plot ? (in R)

    - by Tal Galili
    Hi all, I came across this interesting website, with an idea of a way to visualize a clustering algorithm called "Clustergram": I am not sure how useful this really is, but in order to play with it I would like to reproduce it with R, but am not sure how to go about doing it. How would you create a line for each item so it would stay consistent throughout the different number of clusters? Here is an example code/data to play with for potential answer: hc <- hclust(dist(USArrests), "ave") plot(hc)

  • Algorithm for dividing very large numbers

    - by pocoa
    I need to write an algorithm(I cannot use any 3rd party library, because this is an assignment) to divide(integer division, floating parts are not important) very large numbers like 100 - 1000 digits. I found http://en.wikipedia.org/wiki/Fourier_division algorithm but I don't know if it's the right way to go. Do you have any suggestions?

  • SQL Server Indexing

    - by durilai
    I am trying to understand what is going on with CREATE INDEX internally. When I create a NONCLUSTERED index it shows as an INSERT in the execution plan as well as when I get the query test. DECLARE @sqltext VARBINARY(128) SELECT @sqltext = sql_handle FROM sys.sysprocesses s WHERE spid = 73 --73 is the process creating the index SELECT TEXT FROM sys.dm_exec_sql_text(@sqltext) GO Show: insert [dbo].[tbl] select * from [dbo].[tbl] option (maxdop 1) This is consistent in the execution plan. Any info is appreciated.
