random - Does any software exist for building entropy pools from user input? -


For some purposes, it would be good to bypass the random number generated from any type of algorithm in favor of natural input --- Dice rolls, for example, cryptographic key generation kills me as a condition where sufficient data needs random data, and it is necessary that the data is actually random, it Gaddafi's more, it can be a very desirable thing to do.

So what do I want to know, before I go and get my hands dirty, is this: Is any software available directly from the random number input to make the entropy pool? Note that this is not enough to convert things from Radix R to Radix 2; For example, for example, 3 and 2 are relatively prominent, changing radix-3 (or radix-6) numbers into binary numbers is not entirely straightforward when capturing maximum entropy in the original input.

The device does the same on Linux - maybe this source is worth seeing?

Edit:

As Joit David says, if enough randmans are unavailable, then / dev / random will be blocked Monitoring external devices for entropy will await "build up" (like a mouse, disk drive), or it may be what you want if you do not want to wait anytime, and possibly less- Are satisfied with quality randomness, instead of / dev / urandom Use - This is a non-blocking pseudo-random number generator which makes available <0> / dev / random whenever available, to make it more random than simple deterministic PRNG (For more information, See man / dev / urandom .)

html - CSS autoheight, but fit content to height of div -

I have a div in which there are three children- div in the left and middle div: float: left while true: float: true because it is my layout Actually will spoil, I've used ClearFix Hack: .cf {zoom: 1; }. Cf: First,. Cf: {content: ""; Display: Table; }. Cf: After {clear: both; } It still works, but I want to be the right div an indicator. So it should fill 100% of the parent unit of height. How can I complete this? PS is the full code: & Lt; / Div & gt; & Lt; Div class = "mobile_content" & gt; & Lt; H5 & gt; {{Data.titel}} & lt; / H5> & Lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Komponist: & lt; / Th & gt; & Lt; TD & gt; {{Data.komponist}} & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Th & gt; Instrument: & lt; / Th & gt; & Lt; TD & gt; {{Data.instrumente}} & lt; / TD & gt; & Lt; / TR & gt;...

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName (). ToUtf8 (). ConstData () & lt; & Lt; Std :: endl; QAudioInput * default_device = new QAudioInput (device_info, format); QIODevice * default_io_device = default_device-> Start (); a QAudioInput.setVolume () method is not you I ...
