True | skulgnome | null | Granted, this was with Firefox 3.5, but it seemed to munch out on the CPU far more often than Vimperator, making it noticeably less responsive.

True | Pandalicious | null | What the OP was saying is that your link wasn't about programming. It falls under the category of "links that programmers might find interesting or funny", which the subreddit guidelines clearly state is NOT what this subreddit is for. That may sound overly harsh when it comes to stuff that's tangentially related to programming like your link, but it's the reason that /r/programming is basically the only large subreddit that hasn't really deteriorated much over the past 3-4 years as reddit's traffic has exploded.

True | jjo241 | null | Removing the comparison has no effect. It could be that the branch predictor is good enough in this case or since in the test matrix I have about 30 nonzeros per row, its just always assuming that i != j.

True | xcbsmith | null | Honestly, I would argue the opposite. Most devs have an instinct to reimplement systems from scratch. It feels right, but in practice it often is not. A lot of those rough edges come from addressing real world problems, but more than that, when you go back to redesign it all, you usually come up with a whole new set of problems. Working software has the advantage that severe problems have been detected and fixed, and generally it is easier to address at least significant problems on an existing codebase, even if your cut tells you otherwise.
The problem is, as engineers, we naturally want to build things, and we see the flaws in everything that has been built, but we often lack the ability to appreciate all the flaws in everything that *could* be built (really, think of all the OS's that were built *after* Unix that haven't supplanted it and often have had to implement Unix compatibility!). I think without that flaw it might be hard for many engineers to work up the mental fortitude to start building something new, so for better or worse, it is a necessary part of the mentality.
We just need to be careful to fight that urge unless the win of a "build it all over again from scratch" system is big enough. | null | 0 | 1317424128 | False | 0 | c2nwq62 | t3_kwhif | null | t1_c2nwq62 | t1_c2nuiga | null | 1427669948 | 3 | t5_2fwo | null | null | null |

True | jjo241 | null | I didn't profile per se (everything happens in one function), but by commenting out sections, I have a pretty good idea where the time is spent.
If i take three sections:
A: Line 29 (initializing each thread's r to 0.0).
B: Lines 36-43 (r = A * x)
C: Lines 57-61 (summing up each threads copy of r)
Original code: 0.0410
A,B,C commented out: 0.0002 sec
B,C commented out: 0.0084 sec
A,C commented out: 0.0345 sec
A,B commented out: 0.0075 sec
A few notes:
with all three commented out the code runs 205x faster, so thread creation/creation of vectors is <0.5% of the time.
My guess is that I'm bandwidth/cache limited (so that srufest's reply is probably the best suggestion). Vectorization may help... but not by too much. Also - I'm half the speed that Intel's presumably hand-tuned routine is... so maybe this is already pretty good? | null | 0 | 1317424293 | False | 0 | c2nwqwq | t3_kwo7p | null | t1_c2nwqwq | t1_c2nv660 | null | 1427669956 | 1 | t5_2fwo | null | null | null |
True | WestonP | null | Yup, you see the error pretty quick when using 32-bit float operations in loops, or to try to express more than 7 significant digits (GPS coordinates are a good example). Simply doubling the bit count is enough to "solve" it in many cases, but the error is still there and still an issue with a large number of operations.
One workaround that I like is using integers for fixed-precision fractional numbers, which can also be very computationally fast if you do it smartly. For a simple example, if I needed to accurately compute numbers to a precision of .001, I would simply multiply the inputs by 1024 and store them in integers, thereby creating a 1/1024 fraction. This is super quick to convert to/from a whole integer, because divide/multiply by 1024 can be directly replaced by a much faster bit-shift by 10 bits. Rounding can also be accomplished with a bitwise right-shift and add from the highest non-shifted bit. On a 32-bit int, that example can store values up to a little over 2 million (4 if unsigned), but using a 64-bit int gives you coverage into pretty huge numbers with room to increase your fractional precision to much more than 1/1024, so you can devise a good general-purpose scheme with that. | null | 0 | 1317424399 | False | 0 | c2nwrco | t3_kwf95 | null | t1_c2nwrco | t3_kwf95 | null | 1427669962 | 3 | t5_2fwo | null | null | null |

True | SupremeFuzzler | null | I used the eeepc version and it works fine. Some tips: set your sound interface to SoundBlaster 16 in VirtualBox if you want sound. Also, you can use it to develop Bluetooth apps (which is something the android emulator can't do). I haven't tried on a PC, but I think you can just plug in a bluetooth usb adapter and select it in the virtual box usb filter list. On a mac, you have to unload the bluetooth daemon:
$ sudo launchctl unload /System/Library/LaunchDaemons/com.apple.blued.plist
You also have to unload Apple's bluetooth drivers:
$ kextstat | grep Blue
to get a list of bluetooth kexts. The one you definitely need to remove is com.apple.iokit.IOBluetoothFamily, but it may have dependent drivers loaded. It's best to do this after a restart and before using any bluetooth devices. To unload the kexts:
$ sudo kextunload com.apple.iokit.IOBluetoothFamily
etc. I wasn't able to unload the com.apple.iokit.IOBluetoothSerialManager, but it doesn't seem to matter.
Once all the built-in bluetooth stuff is disabled, you should be able to attach the bluetooth adapter to the VirtualBox's usb hub. This should work for the built-in bluetooth adapter on a mac, as it hangs of the usb interface. It definitely works with USB bluetooth adapters. | null | 0 | 1317425191 | False | 0 | c2nwurc | t3_kwv50 | null | t1_c2nwurc | t1_c2nw3ll | null | 1427670007 | 15 | t5_2fwo | null | null | null |

Is there LESS 'language' styling for notepad++?
If not, would you be interested in collaborating on such a project? I estimate the max time for each of us would be 4 hours of work - email me if this appeals; I've already done some things like added CSS3 keywords to N++ (langs.xml?), but I am unclear on how to code/specify variables. Email me.
As for browsers adopting LESS (or SASS), I thought someone submitted it to the W3C, but I will accept I'm wrong since I didn't see it in the last 5 minutes of web searching.

True | cdsmith | null | Yeah, I did read your following comments. None of them support the idea that it's hard to write a program in a modern programming language, with a pre-existing modern graphics API, to draw a maze.
Doing so requires precisely *zero* of the algorithms in the list you posted from Wikipedia. It doesn't require any math at all, except for the basic arithmetic you use to decide the coordinates of the endpoints of your walls. If you want to rotate or scale, your graphics API has functions you call to rotate or scale. You don't need to implement anti-aliasing: it's not necessary anyway, and if you want it, your graphics API will do it for you.
This is getting pretty ridiculous. The original question was about how to get enough display code in place to see the results of maze generation. It wasn't about implementing Bresenham line and circle drawing from scratch, or about ray tracing realistic water effects, or about antialiasing. You're just looking for an argument, when there's none to be had.
