• Determining when database zip is unpacked

  - by adehaas

  I am fetching a db zip on initial startup of an AIR app (after 1st install), which I then unpack via FZip. After this operation I immediately need to load data from the generated sqlite db, which fails since I seem not able to determine when the zip is completely unpacked and/or the sqlite has been created. Any suggestions? Thx!

  - by out_sider

  I'm witting an application based on a server and various client but I'm having a problem with the send command. Whenever I do ctrl+c on the client side the send operation kills the thread which is in and the process running (in order to have multiple clients I set a thread to which one). If the client ends (doing the close socket) properly the server doesn't die, but when I use the ctrl+c combination on the client both exit. What can I do to prevent send commando to have this behavior? Thx in advance

• Easy way to keeping angles between -179 and 180 degrees

  - by User1

  Is there an easy way to convert an angle (in degrees) to be between -179 and 180? I'm sure I could use mod (%) and some if statements, but it gets ugly: //Make angle between 0 and 360 angle%=360; //Make angle between -179 and 180 if (angle180) angle-=360; It just seems like there should be a simple math operation that will do both statements at the same time. I may just have to create a static method for the conversion for now.

• Building up an array in numpy/scipy by iteration in Python?

  - by user248237

  Often, I am building an array by iterating through some data, e.g.: my_array = [] for n in range(1000): # do operation, get value my_array.append(value) # cast to array my_array = array(my_array) I find that I have to first build a list and then cast it (using "array") to an array. Is there a way around these? all these casting calls clutter the code... how can I iteratively build up "my_array", with it being an array from the start? thanks.

• Need a scenario where would fail Array.ConstrainedCopy()

  - by Sir Psycho

  Hi, Just playing around with some of the APIs in .NET and I can't seem to find a way to cause Array.ConstrainedCopy() fail. According to MSDN, it's treated as an atomic operation. If it fails during the copy, the entire call fails resulting in no elements being copied as opposed to its Array.Copy() counterpart. Can someone demonstrate this or tell me how to do this?

• How to map a long integer number to a N-dimensional vector of smaller integers (and fast inverse)?

  - by psihodelia

  Given a N-dimensional vector of small integers is there any simple way to map it with one-to-one correspondence to a large integer number? Say, we have N=3 vector space. Can we represent a vector X=[(int32)x1,(int32)x2,(int32)x3] using an integer (int48)y? The obvious answer is "Yes, we can". But the question is: "What is the fastest way to do this and its inverse operation?"
