I'd call it more interesting than helpful (not that it's not helpful). It gives insight into how a web page is actually built -- while I'm sure most readers here understand it, that's not true for the general population.
It might make developers think twice about how they build sites if they could see how overly complex they get. As I mentioned, the Houston Chronicle site used to require about 4x the number of requests as it does now so someone did some optimization.
Not sure if you are asking me or heipei. For my project, it shows the requests on a map, where the requests in dev tools aren't geolocated and mapped. Same basic principle, just a different view.
What it does is show where every asset on a web page is loaded from. It allows you to visualize how many different requests go into building just one web page. While it's gotten much better, the Houston Chronicle (https://chron.com) used to make about 500 individual requests to build its home page. It's down to about 125.
It's best to run it across two different monitors, with IP Request Mapper on one monitor and your "normal" browser window on another. Then enter any URL and watch the map start populating based on the geolocating every request made by the page.
But it's projects like ipinfo.io that make these other things possible. Standing on the shoulders of giants and all that...kudos to you, coderholic.
Believing that the last digit of primes is evenly distributed overall is not the same as thinking they do not exhibit patterns when viewed sequentially. I'm surprised by neither.
It's not an unexpected property to me. In particular, I would never have assumed an even distribution of last digit of primes. I'm not sure why this is so magical. It's only so if you assumed it should be evenly distributed to begin with, and there's no particular reason I can think of why this would be so.
Very cool. I've been doing this for about 3 years in Las Vegas for the VegasTech community. It is definitely a great way to meet other people and it keeps you from getting too focused on your own thing and not getting other perspectives.
I've also signed up for startuptravels as it looks to be a great way to create conversations.
