What are the general disadvantages to most frameworks?
- by JamieC
I'm trying to come up with a list of negative reasons for the use of frameworks. I know there are many advantages, such as partially complete solutions (Collections, Exception handling, etc).

Any help would be a life saver! Thanks in advance!Read the article

Help me understand FFT function (Matlab)
- by estourodepilha.com
1) Besides the negative frequencies, which is the minimum frequency provided by the FFT function? Is it zero? 2) If it is zero how do we plot zero on a logarithmic scale? 3) The result is always symmetrical? Or it just appears to be symmetrical? 4) If I use abs(fft(y)) to compare 2 signals, may I lose some accuracy?Read the article

How do you make a wrapped div fill the window horizontally?
- by Alex Parkinson
I have a div which is contained by another 960px-wide centered div. I'm adding a background to the inner div which should expand all the way to the window's edges horizontally, essentially escaping the boundaries of its container. If I apply a large negative margin and equal amount of padding, this works on the left side, but the right side causes a scroll bar to appear. Does anyone know how I can achieve this without causing scroll bars?Read the article

A regex to match a substring that isn't followed by a certain other substring.
- by Rayne
I need a regex that will match blahfooblah but not blahfoobarblah I want it to match only foo and everything around foo, as long as it isn't followed by bar. I tried using this: foo.*(?<!bar) which is fairly close, but it matches blahfoobarblah. The negative look behind needs to match baranything and not just bar. The specific language I'm using is Clojure which uses Java regexes under the hood.Read the article

Android Speed based on accelerometer values
- by fraguas
Hi. I need to obtain the velocity of an android device, based on the accelerometer values. I made a code that allows me to get the accelerometer values, and then I calculate the velocity, using the formula: v = v0 + at. (vector calculation) My problem is that my velocity only increases and never decreases. I think the problem is that the device never gets an negative acceleration. Can you help me with this?Read the article

carry flag and subtraction issue!
- by Zia ur Rahman
If a large number is subtracted from a smaller number then borrow is needed. The carry flag plays the role of borrow during the subtraction operation. Now suppose we want to subtract 56 from 66, obviously the borrow is needed and carry flag will be set. Now how this subtraction is performed to get the result -10, how computer will distinguish that the result is going to be a negative number. Please explain the process.Read the article
