    [–] Why does sending thousands of files (e.g. mp3) takes so much time than sending (from one device to another device) a single file of the same size as of the total size of those thousands files? daed1ne 0 points ago in askscience

    A number of things come into play here, many of which were mentioned by others. What most seemed to have missed however is your implication of transfer from a computer to an external device.

    There are many ways for such a transfer to happen each having a different overhead. USB has 3 major versions by itself; then you have thunderbolt, IEEE 1394(firewire/ilink), and more each with their own, usually light, overhead. To make matters even more complicated there are several different protocols that can be used to transfer files over those interfaces. USB can act as a raw file system or provide only a basic interface to manipulate files. In the later case the transfer is often hampered by a unidirectional serial transfer protocol. As an example(made up to illustrate) of the later with the computer being required to wait for confirmation of each before continuing:

    1. Create new song
    2. Set song title
    3. Set song artist
    4. Set album, year, etc one by one(newer specs support consolidating this, though it may still require more than one action to set all)
    5. Transfer song data
    6. Repeat all of the above for each song

    Even the more addressed problem of disk to disk within a computer will often have serious overhead per file as opposed to one large file. An example(made up to illustrate) that would also apply to USB mass storage and hidden under the above hypothetical song transfer:

    1. Check permissions on source file
    2. Journal what is going to be done
    3. Locate free space and mark as not free
    4. Create file entry with name, permissions, creation time, space used(not size but the location), and other metadata(usually stored together but can be spread out)
    5. Copy file data
    6. Enter file entry into the appropriate directory entry possibly requiring the extension of the directory entry
    7. Mark journal entry as complete
    8. Repeat all of the above for each file

    Thats just for a basic transfer other activities such as indexing, thumbnail generation, virus scanning, etc can add to this, but the bulk of that work can be done asynchronously.

    [–] Why did the icon on the tabs turn red? Is there a way I can force it back? daed1ne 7 points ago in OutOfTheLoop

    I haven't tried it but this should do what you want. Reddit links a ton of different favicons only one of which isn't red(I looked at 5) but the selection algorithm isn't standardized so I have no idea why your chrome is using one of the reds while mine is still using the white. It could be because my cache hasn't updated, or maybe your running a higher dpi now, or maybe it just knew it would bother you.

    [–] 65 in a 25. Texting. She hit my parked truck. No brakes. Pushed it 20 feet forward. daed1ne 1 points ago * (lasted edited 9 days ago) in pics

    Not sure where to stand on this. On one hand thats far more egregious than anything I ever did as a kid, on the other staying over night in lockup awaiting bail won't do anyone any good. If 65-0 didn't scare her straight nothing will.

    Really what we need is better drivers education with mandatory defensive driving classes. That and swap the minimum ages for driving and drinking. It's pretty clear to me that 16 year olds are not mature enough to drive responsibly, I know I wasn't.

    edit: saw OP saying she was on the phone bragging with her friends further down, maybe a night in lockup would help bring her down to earth.

    [–] Cheerleader does an impressive move Part 2. daed1ne 4 points ago in gifs

    Using data from US Dept. of Ed.:

    • 1837/1951 men's basketball teams are profitable
    • 827/878 men's football teams are profitable
    • 33/2058 athletics departments are profitable

    Initially I subtracted "Not Allocated by Gender/Sport Revenue" assuming it to be mainly the school injecting money into the program. Cross referencing with NCAA Data shows it also included donations. From that data only 13/230 were profitable enough to cover the entire athletics program.

    [–] Man outside Lincoln Memorial wants people to know the American way daed1ne 1 points ago in pics

    I'd agree were it not for the fact that many of the rights opinions/values are founded upon lies. As an example voter fraud is nearly non-existant, 4 documented cases in 2016, yet it is used as an argument in favor of voter ID laws. What those laws would actually do is decrease voting among the poor. It is a bit of a stretch, but I'll admit that at it's core wanting to disenfranchise poor voters is an opinion, and it is their right to believe in it. In this context believing that we need voter ID laws to combat rampant voter fraud is not an opinion.

    It is like arguing that the world is round to a flat earther(I'm still not convinced they really exist in numbers but I think that is just misplaced faith in humanity). They don't care what evidence you have, you're wrong. Nevermind the idiocy of praising free speech and then turning around demanding that it be illegal to burn the flag.

    Personally I like when something I'm wrong about is pointed out to me, because then I can stop being wrong about it, but when most people are shown to double down when their inaccuracies are pointed out I don't know of any meaningful response.

    [–] Is a blank 15 minute MP3 the same size as a 15 minute MP3 of music? daed1ne 2 points ago in askscience

    Assuming your music comes from the itunes store it is actually 256kbps VBR AAC(as of 2014, may have changed) so the silence should be a miniscule portion of the file size.

    [–] Does it take a computer more time or resources to compute 17*7 compared to 2*3? daed1ne 1 points ago in askscience

    Multiplication is implicitly a parallelizable operation. For a 32bit multiply in psuedo-code since I can't think of a clearer way to prepresent it:

    r = 0
    do 32 times:
     if(1 & y):
        r += x
      x << 1
      y >> 1

    Neither of the shifts are "real" in a circuit just lots of traces and diodes. All thats really needs to be done are the parallel sums 16, 8, 4, 2, and 1. Most modern CPUs manage that in 3-5 cycles, not varying based on input, but the exact instruction used.

    Link explaining it and with an interactive demo to test your keyboard. If you play with it you will see it isn't a hard number limit rather certain combinations will fail. For example, when pressed and held in order "asdfghjkl"->"asdf" but "asdfhl"->"asdfhl" and "sdfg"->"sdf", my ancient keyboard does not like "g".

    edit: forgot to mention there are a few pricier keyboards that support many more keys, MS apparently made one that can report any combination of 17 standard keys up to 26 including modifiers like shift.

    [–] Can alcohol intake during early pregnancy affect the embryo/fetus before the umbilical cord is developed? If so, how? daed1ne 1 points ago in askscience

    I think what /u/stefantalpalaru was saying is that the confounders included things such as smoking during pregnancy and whether the mother currently drinks. Adjusting for those is likely to adjust for drinking during pregnancy leaving little significance to the results.

    [–] What do the comments mean by "stop outing the immortals they'll come out when they're ready"? daed1ne 1 points ago in OutOfTheLoop

    I don't think it references anything. The painting is from 1891 and the girl in the foreground looks similar. Thus she is the girl in the painting and is immortal.

    [–] Our Trade Site and Manifesto daed1ne 6 points ago in pathofexile

    Yeah, I follow this sub just in case they do something to warrant my coming back. It's disheartening to see them spend a year to implement what I hear is a shitty imitation of Sure, the AFK distinction is kinda nice, but where is something actually meaningful like cross-instance trading? Oh, thats right can't actually have anything to make trading less of a pain in the ass(not sarcasm or joking, just read the new trade manifesto).

    Googled postage rates in Australia, didn't explain it. Mailing would be less than $10 million. Quick and reliable counting would be another $10 million, or a few hundred thousand if you were patient since precision accuracy shouldn't be worth millions for a poll.

    edit: forgot printing and stuffing, but that should only be $2-3 million, far short of the missing $100 million.

    Made me curious so I googled a bit trying to get an idea of how many slippled through this way and couldn't find anything. Your license doesn't have a LOFS(licensed driver over 21 in passenger seat) restriction does it?

    [–] He has no excuses to give daed1ne 1 points ago in gifs

    I guess I was over generalizing a bit. I just meant that unless you have taken a defensive driving course or practiced most people make things worse rather than better by swerving.

    [–] He has no excuses to give daed1ne 1 points ago in gifs

    I guess it's more that I don't trust other drivers to be able to safely do that in the first place.
