• Multiple requests to server question

  - by embedded

  I have a DB with user accounts information. I've scheduled a CRON job which updates the DB with every new user data it fetches from their accounts. I was thinking that this may cause a problem since all requests are coming from the same IP address and the server may block requests from that IP address. Is this the case? If so, how do I avoid being banned? should I be using a proxy? Thanks

• What makes C faster than Python?

  - by Chris

  I know this is probably a very obvious answer and that I'm exposing myself to less-than-helpful snarky comments, but I don't know the answer so here goes. If Python compiles to bytecode at runtime, is it just that initial compiling step that takes longer? If that's the case wouldn't that just be a small upfront cost in the code (ie if the code is running over a long period of time, do the differences between C and python diminish?)

• [Linux] Incremental search on command line?

  - by florianbw

  I'd like to write small scripts which feature incremental search (find-as-you-type) on the command line. Use case: I have my mobile phone connected via USB, Using gammu --sendsms TEXT I can write text messages. I have the phonebook as CSV, and want to search-as-i-type on that. What's the easiest/best way to do it? It might be in bash/zsh/perl/python or any other scripting language. Thanks!

• `export PS1='value'` does not propagate to (Korn) subshells for root?

  - by user319845

  Please consider the following /root/.profile: export PS1=value1 export x=value2 How come the login shell shows the expected prompt (and $x as value2), while the subshells keep showing $x as value2 but $PS1 as '#'? Just in case, I'm trying this under OpenBSD. [Yeah, I know... What on earth am I doing with OpenBSD if I don't know this? Just toying... in an isolated, most definitely non-production VM =).]

• how do i use @var on a function variable?

  - by fayer

  i've got a variable $user that is of data type User (a class). i've got it in a class method so i can't just type: /** * @var User */ $user = Factory::getInstance('User'); because that will work only with class properties, not method variables like in this case. how could i tell netbeans that that variable is of data type User in a method? Thanks!

• XML Document straight to Stored Proc Mapping in NHibernate

  - by ZekeTheGeek

  Hello. I'm building a mechanism to take XML data from a queue and call stored procs to save the data from the XML document directly to the database. This seems like something that NHibernate could address, but of course most of the information I find discusses going from objects to database instead of another data format (XML, in this case). Is there a way to use NHibernate in this fashion or am I barking up the wrong tree? Thanks.

• DirectorySearch.PageSize = 2 doesn't work

  - by Bero

  using (DirectorySearcher srch = new DirectorySearcher(String.Format("(memberOf= {0})",p_Target.DistinguishedName))) { srch.PageSize = 2; SearchResultCollection results = results = srch.FindAll(); int count = results.Count; } count = 3 (THREE) and not 2. Why is that? I don't want to have all results in just one page. I know that PageSize = 2 is silly small but I set that value in this case just for testing purpose (in reality it will be more).

• Jquery live() vs delegate()

  - by PeeHaa

  I've read some posts here and on the web about the differences of live() and delegate(). However I haven't found the answer I'm looking for (if this is a dupe please tell me). I know the difference between live and delegate is that live can not be used in a chain. As I also read somewhere delegate is in some case faster (better performance). So I am wondering is there a situation where you would use live instead of delegate?
