问题 I started to use AWS Elasticache with my django web app. I started by setting the cache location to the unique endpoint using the auto-discovery feature, but it doesn't seems to work.

How can I enable it? 回答1: Quick answer Yes for django: django-elasticache Long Answer ElastiCache provides memcached interface so there are three solution of using

问题 I’ve recently found out an odd thing. It seems that calculating Collatz sequence lengths with no caching at all is over 2 times faster than using std::unordered_map to cache all elements. Note I did take hints from question Is gcc std::unordered_map implementation slow? If so - why? and I tried to used that knowledge to make std::unordered_map perform as well as I could (I used g++ 4.6, it did perform better than recent versions of g++, and I tried to specify a sound initial bucket count, I

问题 I am using IIS 6 and IIS 7 as a web server. After running Google page speed online , it remarks that I should be: Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network. And it lists a lot of plain images , my javascript files and the style sheets . How can I set this expiry date for these static files ? I thought this was done automatically by the browser ? 回答1

问题 In my app I build a list of objects using data from Firebase. Inside a StreamBuilder, I check if the snapshot has data. If it doesen't, I am returning a simple Text widget with "Loading...". My problem is that if I go to another page in the app, and then come back, you can see for a split second that it says 'Loading...' in the middle of the screen, and it is a bit irritating. I am pretty sure it is downloading the data from Firebase, and building the widget every time I come back to that

问题 I want to create an application wide feed on my ASP.net 3.5 web site using the application cache. The data that I am using to populate the cache is slow to obtain, maybe up to 10 seconds (from a remote server's data feed). My question/confusion is, what is the best way to structure the cache management. private const string CacheKey = "MyCachedString"; private static string lockString = ""; public string GetCachedString() { string data = (string)Cache[CacheKey]; string newData = ""; if (data
