ixtjpf | Why do download speeds always seem to drop-off towards the end of a download? | It seems like any time I download a file, it always slows to a complete crawl for the last few percent of the download. When downloading a game through Steam for example, I can get speeds of up to 30MB/s, but the last 5ish percent of the download seems to take as long as the preceding 95 percent. Why is this? I have a ... | Technology | explainlikeimfive | {

ixws9f | Why are most older music videos on YouTube uploaded all around the same time? | I’ve noticed there is a whole host of music videos uploaded in late 2009. These were all music videos released prior to this day. Did the music rights on YouTube change on this day? Why was everything uploaded then and not earlier? | Technology | explainlikeimfive | {

"Most of them are under VEVO so my educated guess would be that VEVO was created around this time, and acquired the rights to upload the videos then. Don't forget that YouTube wasn't the behemoth that is today before the 2010. Right at the 2010-mark was when YouTube expl... | [

ixwtv5 | How are bots utilized by scalpers able to avoid failsafes most websites have in place today, such as captchas & active fingerprinting? | Given all the news about bots snatching up the PS5 & Xbox preorders that recently went on sale, I think it would be very beneficial for more of us to understand these kinds of things.
