• Cleaning up images in matlab

  - by Taegeuk

I've got fuzzy square images about the same size and then inside the fuzzy square there's smaller fuzzy squares, and I want to clean up the larger squares - not the smaller ones - so that they are no longer blurred. It looks like I'd have to make some type of morphological mask, but I'm not sure how in this case.

• 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

  - 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 =).]

• What is the rationale for difference between -> and . in c++ ?

  - by Good Person

  I know the difference between the member operator (.) and the member by pointer operator (-). Why did the c++ designers create a different operator for this access? Why can't the compiler figure it out on its own? If you always used a . does any case exist where it is ambiguous whether you mean a member or a member by pointer?

• 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?

• Combine file transfer dialogs

  - by SamuelDavis

  I am considering upgrading my work computer to use windows 8 as the new file transferring feature seems very useful. Unfortunately after installing windows 8 on my home pc to test it out, the files are being transferred in separate dialogs as opposed to this image provided by microsoft. As I am transferring files constantly a single transfer dialog would make things much less confusing. Does anyone know what settings to change to make file transfers appear in the same window?
