point-of-interest

I am wondering why so many examples read byte arrays into streams in chucks and not all at once... I know this is a soft question, but I am interested. I understand a bit about hardware and filling buffers can be very size dependent and you wouldn't want to write to the buffer again until it has been flushed to wherever it needs to go etc... but with the .Net platform (and other modern languages) I see examples of both. So when use which and when, or is the second an absolute no no? Here is the thing (code) I mean: var buffer = new byte[4096]; while (true) { var read = this.InputStream.Read

I currently have a webapp which draws points of interest using the maps api, however I have noticed a small annoyance which I would like to turn off if possible. Right now when the google map is loaded, it will show points of interest and local business (city hall, pizza hut, etc...). I don't mind the wording showing up labelling them, but I do not want these points clickable, as if often happens that people using touchscreens hit these points accidentally Is there a way to turn this feature off? You can turn them off using map Styling . The specific style would be [ { featureType: "poi",

Correct me if I'm wrong. There are three approaches to get the nearest homes, users have created in my website: To create a table with two columns(latitude, longitude) that both of them are float and say: Here it is: $latitude = 50; $longitude = 60; SELECT * FROM my_table WHERE (latitude <= $latitude+10 AND latitude >= $latitude-10) AND (longitude <= $longitude+10 AND longitude >= $longitude-10) that 10 here means 1km for example. In this approach we can also use harvesine formula. To merge those columns(latitude, longitude) to one column named point as POINT type and again search each row one
