由 人盡茶涼 提交于 2019-12-20 09:37:57
问题 I have a query that attempts to find things within a certain geolocation, but the results that it brings back are a little bit... strange. I had previously posted this thread and the community helped me find a formula that I needed: Querying within longitude and latitude in MySQL but the query now gives really wacky results. My data is surrounding the city of San Francisco which has the lat/lng 37.780182 , -122.517349 Query: SELECT id, hike_title, lat, lng, ( 3959 * acos( cos( radians(37) ) *

由 倖福魔咒の 提交于 2019-12-20 05:47:07
问题 So, I was told in my previous question that I can use the databases provided by MaxMind to determine locations. So, I got their databases downloaded from their site.

Can't turn on location on android api23?

问题 I have used the following code and the dialogue that asks for permission shows as expected. But when I click "allow" it doesn't do anything. The log message doesn't appear as if the permission wasn't granted so I went to my parameters to verify if location is "on" and it was "off". Wasn't it supposed to be on because I granted the app access to my location ? If I manually turn it "on" and then run the app again, once it asks for my permission, it works and shows the log message but isn't the

Global location input autocomplete

由 杀马特。学长 韩版系。学妹 提交于 2019-12-20 02:34:26
问题 I was looking for a plugin to create a smart location form field which has a suggested autocomplete. I was unable to find anything suitable (Google Geocode is too unreliable on its own, and it isn't designed for this) so I built my own. I thought it was crazy that in 2011 an open-source global location input plugin like this didn't exist so set out to give it a go. The demo is here http://labs.unxposed.net/unxposed/geocode/ and is working on Chrome and Firefox 4. Download is here https:/
