  There is a simple application written in C, which uses only standard C library functions (from stdio, stdlib, etc.) and Makefile+GCC to build it. Now, I wanna port it to iPhone OS for iPhone/iPads. Will it be seamless or are there any possible incompatibility issues?

• echo that outputs to stderr

  - by BCS

  Is there a standard bash tool that acts like echo but outputs to stderr rather than stdout? I know I can do echo foo 1>&2 but it's kinda ugly and, I suspect, error prone (e.g. more likely to get edited wrong when things change).

• Online Hotel Booking System, Simultaneous Booking?

  - by KiiroSora09

  I'm asked to create an online booking system with online payment and I'm wondering what to do in the case when 2 customers booked for the same room(s) at the same time. For Example: At the same time: Customer1 and Customer2 booked for a standard room which only has 1 room available. (The Room availability will display that there is still 1 room available). And then they hit the 'confirm' button at the same time.

• C++: Initialization Order for Member Classes

  - by Nikhil

  In the following code, when the ctor of X is called will the ctor of A or B be called first? Does the order in which they are placed in the body of the class control this? If somebody can provide a snippet of text from the C++ standard that talks about this issue, that would be perfect. class A; class B; class X { private: A a; B b; }

• samsung netbook OS for clean install

  - by Alex

  Hello - I recently had a problem with a corrupted registry on a samsung N120. When all else failed i reformatted the drive. However having bought the machine with windows home ed pre-installed, I didn't have original windows disck for the clean install. So I managed to install another edition of windows XP (PRO this time). Now windows opens, but several key functions are missing. e.g.: screen resolution - will not allow me any but 800x600 resolution native buttons - such as the fn + screen brightness is not working at all. Any suggestions please? ? Is there a way to get the samsung OS online (since I do have the manufacturer's/installed product key)? thanks PS: It has been my intention to install ubuntu, but i need to know i will not lose functions like screen brightness, volume, and the trackpad's scrolling function. I'd be happy to bypass the windows option if i was sure to have full keyboard/samsung functionality

• How do I set up a mailing list for over 2000 people?

  - by John Hoffman

  I manage IT for a large organization with over 2000 people. The administration would like to send an email (often with up to 5 word document attachments) about once per week. They also want to categorize people. For instance, about 40 people are "teachers," about 1800 people are "students," and about 10 people are "board members." They may send an email to any combination of these categories. Here's what I have tried: I bought a server, installed Ubuntu server edition on it, and wrote a python script to send out their emails. However, pretty soon, mail services such as Gmail and Yahoo began to treat the mail I send out as SPAM. I'm guessing this is because I am sending an email with 2000+ people in the "bcc" field. Maintaining this server also takes a lot of time. How do I set up a mailing list for over 2000 people? Must I defer to paid services?

• Sorting MySQL table by next due date

  - by Zagga

  Hi folks, I have a MySQL table that stores (amongst other things) a persons date of birth. Is there any way to sort the table so the next due birthday is at the top? I have the date stored in standard yyyy-mm-dd DATE format and seperate year, month and day fields so I can sort it by the first birthday of the year (ORDER BY month, day) but I can't seem to get any further. Any help would be greatly appreciated. Zagga

• possible to create custom scrollbar graphics without flash?

  A friend is wanting me to help her convert her flash based website to html. She has an embedded textbox with a scrollbar that is using a flower instead of a normal scrollbar.

• Postion of & to denote reference type

• Regular expression - skip string in quotes using sed

  - by milano

  I have string like this: "Some standard text CONST_INSIDE_QUOTES" blah blah CONST "There might be another quotes" The thing is, that i want to replace all constants in string with some text, but it mustn't be applied on constants inside text in quotes. I have this regex: sed "s/([A-Z][A-Z0-9_]*)([^a-z])/<span class=\"const\"\1<\/span\2/g" which of course works for all consts. Any ideas how to exclude its apply on quotes constants?

• Usage of peripheals (special hardware) to make programming more efficient?

  - by John M

  Outside the standard mouse/keyboard combination are there any other peripheals that you use to make you programming more efficient? One option that I have considered is using AutoHotKey to script the buttons on a Logitech Wingman to run different functions/keystrokes that are not available on the keyboard.

• Where namespace does operator<< (stream) go to?

  If I have have some overloaded ostream operators, defined for library local objects, is its okay for them to go to std namespace? If I do not declare them in std namespace, then I must use using ns:: operator <<. As a possible follow-up question, are there any operators which should go to standard or global namespace?

• Safe division function

  - by bugspy.net

  I would like to define some kind of safe division (and modulo) function, one that would return some predefined value when attempting to divide by zero. I don't want to throw exceptions, just to return some "reasonable" value (1? 0?) and continue the program flow. Obviously there is no correct return value, but I wonder if there is some standard or known approach to this
