Re: Warming up PRNGs

and ran PractRand a few times with the 1KB switch and got no anomalies with the early numbers generated. Further tests see the odd small anomaly creeping into the early generations, so I have increased the warm up to 8192 ( 32KB ). Sebastian Vigna will think me mad but 8192 is still costing me a ne...

Re: Warming up PRNGs

I listen to music on my PC, mostly mp3/4 from YouTube. OK, mp3/4 is not as good as CDs but the sound isn't too bad. I use Sennheiser HD 600s, but they are too good for the cheap DAC in my PC, so I got an AudioQuest DragonFly DAC USB - Cobalt. I could have spent a lot more on the DAC, pretty close to...

Re: Warming up PRNGs

When I say 'source hardware' I mean a stylus or a DAC. Any distortions in them will get amplified.: Rubbish in, rubbish out. Many years ago I had a bog standard CD player which compromised transport and DAC in one. I bypassed the DAC with a better quality replacement and it made a world of differenc...

Warming up PRNGs

There is a lot more about warming up random number generators on the internet than there used to be. [1], (2010), is a good general read and mentions warming up. With Hi-Fi if we spend very little on the source hardware and a lot on the speakers then we will not get good audio. We need to spend more...

Re: Getting old

Unless, indeed, we find other places (planets) where we can live. For humanity to survive, even with a life expectancy, that has been put forward quite a few times over the years. Stephen Hawking was a great advocate. There is nothing in our solar system worth populating, in so far as an off the sh...

Re: Getting old

How would we know the the difference? What, between an alien race and some deity? Well, that is easy enough. If an alien race is capable of correcting us there would be a strong likelihood of them being without sin. Some, if not all, of deity are riddled with sin and spend an inordinate amount of t...

Re: Getting old

So you will continue to eat dogs and cats? He probably will if he still has some Infinity Gems left. He will run out which will be a blessing for cats and dogs and the rest of us I shouldn't wonder. I have no objection to an alien race correcting us but the thought of some deity getting involved ma...

Re: Getting old

It you know the full state of the universe, location and speed of every existing particle, then there are probably no random numbers. I think that may be true of the relativistic universe but not of the quantum universe. Maybe only an older person can understand the extent of the damage, also, most...

Re: Getting old

What is the opposite of random numbers? Chaos theory. Randomness is deterministic. Take RND for example. If we calculate the average it will tend to 0.5 as we increase the number of samples. Well, not quite 0.5 as RND is within [0,1). It doesn't matter what the starting position is, the seed, we st...

Your passion with random number generators It is not a passion with random number generators, per se, but a passion with random numbers. What interests me with generators is how authors go about minimizing the correlation between the latest number generated and its predecessor. With Sebastion Vigna...

Re: Getting old

@marcov I have seen that list and others as well. Like most people I have had my 'ups and downs' and during my downs resorted to writing quips. I knocked out quite a few over the years and eventually put them altogether on my Atari computer in the eighties and added to the list as time went on. I ma...

That made me chuckle but I suspect many will not understand it. If it is any consolation I suspect that it made Oscar Wide chuckle as well.
