• What is the difference between check and foreign key?

  - by GigaPr

  Hi, i am quite confused about the difference between a FOREIGN KEY and CHECK constraint. they appear to me to achieve the same result. I mean I could create a table and enforce a Foreign key on another table, but i could create a CHECK to ensure the value in in another table. What is the difference and when to use the one or the other? thanks

• how to stop an app on heroku

  - by yuri

  I have an app on heroku which is being used by few users. However, I notice there are some data issues which i'd like to fix and stop the app in the mean time so users don't enter anything new. Is there a way to stop the app on heroku rather than destroying it? I see that restart server command is there ...though I don't see anything like 'stop'

  - by mystify

  ...i mean... will they reject my app if I simply make my own COPY button at the most appropriate place in my app, for copying something to the clipboard? Or must I do that with some standardized ugly way like shaking the luxury device to death for getting some copy/paste overlay?

• Java overloading and overriding

  - by Padmanabh

  We always say that method overloading is static polymorphism and overriding is runtime polymorphism. What exactly do we mean by static here? Is the call to a method resolved on compiling the code? So whats the difference between normal method call and calling a final method? Which one is linked at compile time?

• empty base class optimization

  - by FredOverflow

  Two quotes from the C++ standard, §1.8: An object is a region of storage. Base class subobjects may have zero size. I don't think a region of storage can be of size zero. That would mean that some base class subobjects aren't actually objects. Opinions?

• Complicated programming and math tasks online. Any?

  - by Tom

  Maybe it is not very thematic question in here, but I guess it will be interesting not only to me. I hope. So, I just want to get some cool tasks to do using programming languages or just pen and sheet of paper. I guess it can lead to improving my ability to do better code (more optimal I mean.) Do you know any websites where I can find it? Thanks.

• Why should I use display:table instead of table

  - by nimo9367

  What's the benefits of structuring my site with divs and apply the display:table property ( display:tr, display:tr). Doesn't this mean that the divs will behave exactly like tr and td elements? I know I probably shouldn’t use tables or table behavior for layout at all but I'm just curious if there's a difference and a benefit?

• Difference between macros and functions in C in relation to instruction memory and speed

  - by DAHANS

  To my understanding the difference between a macro and a function is, that a macro-call will be replaced by the instruction in the definition, and a function does the whole push, branch and pop -thing. Is this right, or have I understand something wrong? Additionally, if this is right, it would mean, that macros would take more space, but would be faster (because of the lack of the push,branch and pop instructions.), wouldn't it?

• C++ header file and function declaration ending in "= 0"

  - by Adam

  hi, I have the following code inside the .h file and I'm not sure what does the assignment statement do and how is it called properly? virtual void yield() = 0; I thought that the function returns a value of 0 by default but since this function returns void I am a little bit confused. Can anyone comment on this and maybe say how can I refer to this assignment, I mean how is it called in C++ jargon? Thanks.

• Implemenation of a pass through file system

  - by user3491505

  Can anyone give me inputs on how to implement a pass through filesystem using fuse?? What I mean by this is that you mount your FUSE file system somewhere (say in /mnt) such that the FUSE file system passes all filesystem calls to some other place (say /home/user). For example, when you go into the /mnt directory and run "ls", this would pass the file system calls to execute ls through and run them on /home/user, such that the directory contents of /home/userwould be listed

• Where am I? * (no branch)

  - by Neofizz

  I've been getting familiar with creating, merging and deleting branches. I like to know where I am so I don't commit work into the wrong branch. I use git branch -a to see which branches I have. I think the asterix * shows which branch I'm currently on. What does it mean when I get: * (no branch) master origin/HEAD Because when I $git checkout mybranch I expect to see * mybranch master origin/HEAD
