  • Static Variables in Overloaded Functions

    - by BSchlinker
    I have a function which does the following: When the function is called and passed a true bool value, it sets a static bool value to true When the function is called and passed a string, if the static bool value is set to true, it will do something with that string Here is my concern -- will a static variable remain the same between two overloaded functions? If not, I can simply create a separate function designed to keep track of the bool value, but I try to keep things simple.

  • Javascript new object (function ) vs inline invocation

    - by Sheldon Ross
    Is there any considerations to determine which is better practice for creating an object with private members? var object = new function () { var private = "private variable"; return { method : function () { ..dosomething with private; } } } VS var object = function () { ... }(); Basically what is the difference between using NEW here, and just invoking the function immediately after we define it?

  • pthread and child process data sharing in C

    - by mustafabattal
    hi everyone, my question is somewhat conceptual, how is parent process' data shared with child process created by a "fork()" call or with a thread created by "pthread_create()" for example, are global variables directly passed into child process and if so, does modification on that variable made by child process effect value of it in parent process? i appreciate partial and complete answers in advance, if i'm missing any existing resource, i'm sorry, i've done some search on google but couldn't find good results thanks again for your time and answers

  • How do I set up an email server that automatically maintains a list of previous recipients?

    - by hsivonen
    I want to set up an email server with the following characteristics. What software (besides bogofilter and clamav that I'm naming) should I use and what HOWTOs should I read? The server should run some flavor of Linux that's as low-maintenance as possible and self-updates for security patches in a timely fashion. (Debian stable?) When email is sent, all the recipients are stored in the list of previous recipients maintained by the server. Scan incoming messages with clamav and treat as spam if it contains viruses. When email arrives (if it passed clamav), if the sender is on the list of previous recipients, bypass spam filter. If the List-Id header names a mailing list on a manually maintained list of known-clean mailing lists, bypass spam filter and deliver into a mailbox depending on the mailing list name. Email that wasn't from previous recipients, manually white listed domains or mailing lists gets filtered by bogofilter. Spam goes into a spam mailbox. Email considered to be ham should automatically be fed to bogofilter training as ham. Email considered to be spam (incl. messages with viruses) should be automatically fed to bogofilter training as spam. There should be mailboxes for false ham and false spam that an IMAP client can move email into so that the server retrains bogofilter appropriately. Email sending requires SMTP over SSL. Email reading requires IMAPS. Should I also want to use SpamAssassin in addition to bogofilter?
