  • What is the difference between PS1 and PROMPT_COMMAND

    - by Jed Daniels
    While taking a look at this awesome thread I noticed that some examples use PS1="Blah Blah Blah" and some use PROMPT_COMMAND="Blah Blah Blah" (and some use both) when setting the prompt in a bash shell. What is the difference between the two? An SO search and even a bit of broader google searching aren't getting me results, so even a link to the right place to look for the answer would be appreciated. Thanks!

  • Visual NHibernate from Slyce

    - by dotnetdev
    I found this tool Visual NHibernate at http://www.slyce.com/, but a search on here has not brought anything up for what I would have thought would have been a very popular product, in concept anyway. Has anyone used this product? Any feedback on it? Thanks

    our site is developed in ASP.NET. We want to block Default.aspx page from Google and other search engines. How can we "close" the Default.aspx page so that it is not accessible? Or is there another way to solve the problem so that we don't create duplicate content.

  • Why "Finalize method should not reference any other objects" ?

    - by mishal153
    I have been pondering why it is recommended that we should not release managed resources inside finalize. If you see the code example at http://msdn.microsoft.com/en-us/library/system.gc.suppressfinalize.aspx , and search for string "Dispose(bool disposing) executes in two distinct scenarios" and read that comment, you will understand what I mean. Only possibility I can think of is that it probably has something to do with the fact that it is not possible to predict when finalizer will get called. Does anyone know the right answer ? thanks, mishal

  • Django logs: any tutorial to log to a file

    - by Algorist
    Hi, I am working with a django project, I haven't started. The developed working on the project left. During the knowledge transfer, it was told to me that all the events are logged to the database. I don't find the database interface useful to search for logs and sometimes they don't even log(I might be wrong). I want to know, if there is an easy tutorial that explains how to enable logging in Django with minimal configuration changes. Thank you Bala

  • Detect winning game in nought and crosses

    - by Dennis
    I need to know the best way to detect a winning move in a game of noughts and crosses. Source code doesn't matter, I just need a example or something I can start with. The only thing I can come up with is to use loops and test every direction for every move a player makes, to search for e.g five in a row. Is there a faster and more efficient way?

  • How can I tell [G]vim where to look for python26.dll?

    - by Ariel
    I have a version of Vim compiled with python 2.6 support enabled (from here). however vim cannot find the python26.dll. :version confirms +python/dyn :version and gvim.exe confirms DYNAMIC_PYTHON_DLL="python26.dll" echo PATH confirms python26.dll is in the search path. (both c:\windows\system32, and C:\python26) What could I be missing? Did I skip something silly?

    I read an article around schema-less database which sounds cool. (http://bret.appspot.com/entry/how-friendfeed-uses-mysql) But what isn't clear to me is how do they run search queries on this data? Since the data is in JSON format how do we look for it?

  • Strange problem publishing a fresh Ruby on Rails 3 application on localhost (Apache, Passenger and VirtualHosts)

    - by user502052
    I recently created a new Ruby on Rails 3 application locally on a Mac OS, named "test". Since I use apache2, in the private/etc/apache2/httpd.conf I set the VirtualHost for the "test" application: <VirtualHost *:443> ServerName test.pjtmain.localhost:443 DocumentRoot "/Users/<my_user_name>/Sites/test/public" RackEnv development <Directory "/Users/<my_user_name>/Sites/test/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> <VirtualHost *:80> ServerName test.pjtmain.localhost DocumentRoot "/Users/<my_user_name>/Sites/test/public" RackEnv development <Directory "/Users/<my_user_name>/Sites/test/public"> Order allow,deny Allow from all </Directory> </VirtualHost> Of course I restart apache2, but trying to access to http://test.pjtmain.localhost/ I have this error message from: FIREFOX Oops! Firefox could not find test.pjtmain.localhost Suggestions: * Search on Google: ... SAFARI Safari can’t find the server. Safari can’t open the page “http://test.pjtmain.localhost/” because Safari can’t find the server “test.pjtmain.localhost”. I have other RoR3 applications setted like that above in the httpd.conf file and all them work. What is the problem (maybe it is not related to apache...)? Notes: 1. Using the 'Network Uility' I did a Ping with the following result: ping: cannot resolve test.pjtmain.localhost: Unknown host and I did a Lookup with the follonwing result: ; <<>> DiG 9.6.0-APPLE-P2 <<>> test.pjtmain.localhost +multiline +nocomments +nocmd +noquestion +nostats +search ;; global options: +cmd <MY_BROADBAND_TELECOMUNICATIONS_COMPANY_NAME>.com. 115 IN SOA dns1.<MY_BROADBAND_TELECOMUNICATIONS_COMPANY_NAME>.com. dnsmaster.<MY_BROADBAND_TELECOMUNICATIONS_COMPANY_NAME>.com.

Since I not changed nothing to the new "test" application, I expect to see the default RoR index.html page: 4. It seems that in the 'Console Messages' there is any warning or error

  • Core Data: fetch an NSManagedObject by its properties

    - by niklassaers
    Hi guys, I have an object NetworkMember that has no attributes but is defined by its relationships Person, Network, Level and Role. In my app, I've found all the four relationships, but I want to make sure not to double-register my NetworkMember, thus I'd like to search for this NSManagedObject before instantiating it. How should I write a query that queries for an NSManagedObject just consisting of relationships? Cheers Nik

  • ACCESS/VBA: How to create a ON/OFF type switch to allow record modification on a form ?

    - by Christian M
    I was using a combobox on my search form to select whether to consult or modify a record. To make it more user friendly (IMO), I put a togglebutton on a form, which controls the .AllowEdits property of my form. This way you can easily switch from reading to writing. However I run into a problem; once .AllowEdits is switched to false, the togglebutton is not clickable anymore ! What are my options ?
