• Does it make sense to have more than one UDP Datagram socket on standby? Are simultaneous packets dr

  - by Gubatron

  I'm coding a networking application on Android. I'm thinking of having a single UDP port and Datagram socket that receives all the datagrams that are sent to it and then have different processing queues for these messages. I'm doubting if I should have a second or third UDP socket on standby. Some messages will be very short (100bytes or so), but others will have to transfer files. My concern is, will the Android kernel drop the small messages if it's too busy handling the bigger ones?

• C# Number of days between two dates problem

  - by Jamie

  Hi all, I have a small problem with the code below, the 'days' variable always seems to be 0 no matter how far apart the days are. Can you see anything obviously wrong?

• PhoneGap iPad lauch screen does not fit

In my Ressorces folder there is only the iPhone launch image which is to small for the iPad, how can I add an other one for the iPad?

• Is there a good library/way to split a big task in as3/flex?

  - by mkorpela

  As flashplayer has only one thread and is event driven, big tasks have to be divided to smaller tasks so that the application stays responsive. For now I've done this with the Timer by doing a small part of work in every TIMER event. Is there a better way of doing this (some library maybe)? What is your recommendation?

• How do you test the usability of your user interfaces

  - by Martin

  How do you test the usability of the user interfaces of your applications - be they web or desktop? Do you just throw it all together and then tweak it based on user experience once the application is live? Or do you pass it to a specific usability team for testing prior to release? We are a small software house, but I am interested in the best practices of how to measure usability. Any help appreciated.

• Lazy non-modifiable list in Google Collections

  - by mindas

  I was looking for a decent implementation of a generic lazy non-modifiable list implementation to wrap my search result entries. The unmodifiable part of the task is easy as it can be achieved by Collections.unmodifiableList() so I only need to sort out the the lazy part. Surprisingly, google-collections doesn't have anything to offer; while LazyList from Apache Commons Collections does not support generics. I have found an attempt to build something on top of google-collections but it seems to be incomplete (e.g. does not support size()), outdated (does not compile with 1.0 final) and requiring some external classes, but could be used as a good starting point to build my own class. Is anybody aware of any good implementation of a LazyList? If not, which option do you think is better: write my own implementation, based on google-collections ForwardingList, similar to what Peter Maas did; write my own wrapper around Commons Collections LazyList (the wrapper would only add generics so I don't have to cast everywhere but only in the wrapper itself); just write something on top of java.util.AbstractList; Any other suggestions are welcome.
