And here I thought it was just an effect caused by the current generation's Short Attention Span Disorder that results in everything needing to be repeated ad infinitum.-4wd (July 15, 2013, 01:23 AM)
In my previous post on shuffling, I glossed over something very important. The very first thing that came to mind for a shuffle algorithm is this:Code: C++ [Select]
It's a nice, simple solution to the shuffling problem:
1. Loop through each card in the deck.
2. Swap the current card with another randomly chosen card.
At first blush, this seems like a perfectly reasonable way to shuffle. It's simple, it's straightforward, and the output looks correct. It's the very definition of a naïve algorithm:A naïve algorithm is a very simple solution to a problem. It is meant to describe a suboptimal algorithm compared to a "clever" (but less simple) algorithm. Naïve algorithms usually consume larger amounts of resources (time, space, memory accesses, ...), but are simple to devise and implement.
An example of a naïve algorithm is bubble sort, which is only a few lines long and easy to understand, but has a O(n2) time complexity. A more "clever" algorithm is quicksort, which, although being considerably more complicated than bubble sort, has a O(n log n) average complexity.
But there's a deep, dark problem with this naïve shuffling algorithm, a problem that most programmers won't see. Do you see it? Heck, I had the problem explained to me and I still didn't see it.

So the first step, in my opinion, is to get a pointing device so I can point it out to others.-Deozaan (July 06, 2013, 03:20 PM)
Uhm, I don't think that laser pointer is going to be powerful enough to mark a star. Plus it would take the laser months to years before it reached the star in question, depending on the distance in light years. If you did get a laser that powerful, it would be military grade and illegal to own. Like, you could shoot down aircraft with it.-Tinman57 (July 06, 2013, 09:36 PM)
the green lasers have been getting very popular in Egypt.-tomos (July 06, 2013, 04:19 PM)
for star identification, in case you are not aware of it, get the software stellarium.

Another one that is very popular at the moment is 'FTL: Faster Than Light' . Set in space. Very basic, very lightweight indie game that I have really enjoyed. Not enough space here to do a full review but check out totalbiscuit's review on YouTube if you want a look at it. Costs about $5 for a DRM free edition or a steam key from ftlgame.com. I'm not affiliated at all just a happy gamer.-nidusin (March 04, 2013, 05:42 AM)
What Amazon is doing is actually likely to encourage the sale of new CDs, which can only help theartistsmusic labels.-xtabber (June 28, 2013, 04:37 PM)
Hi,
Thank you for your feedback. At this time the DNSCrypt client can only be run as an administrator. Our engineers are aware of the behavior with the UAC prompt and hope to have it resolved in future releases. Thanks for your patience while we continue to improve this service.
