Caching in ASP.NET MVC with uncachable forms
asp.net,asp.net-mvc,caching,donut-caching,child-actions
Found a way. Not sure if it's optimal, but it works. Instead of making the form the "donut hole", I make the anti forgery token itself the donut hole.

Caching issue in angularJS application
angularjs,caching,orm,eloquent,slim
Unless you state it, angular will not cache your $http requests, so most likely the values are being cached by your server. There are a couple of things you can do: Pass a header to the server to ignore the cache (assuming your server will react to that header appropriately)...
How to implement immutable cache in Scala?
scala,caching,concurrency,future
If you want to use only things within scala collections, scala.collection.concurrent.TrieMap is a decent choice. However, please be aware that TrieMap#getOrElseUpdate had a thread safety bug that was only fixed recently in 2.11.6. If you can afford the additional dependency, guava cache is quite good for writing such caches. Especially...
With the MESI protocol, a write hit also stalls the processor, right?
caching,architecture,multiprocessing,vhdl,mesi
Do not confuse latency with throughput. Invalidation messages will take multiple cycles to complete but you can pipeline the process. It is possible to built a pipelined cache, that is able to start the processing of new invalidation messages before the previous ones have been completed. The MESI protocol does...
Low level caching for collection
So should I use a cached_books method in the controller like this: Yes, you can. Although there's some gotchas you have to be aware of. Book is ActiveRecord. When you call Book.something (e.g. Book.all, or just even Book.order(:title) it returns you a ActiveRecord::Relation, which is basically wrapper for array...
android - best way to load multiple images locally
Most image loading libraries support multiple sources, not just http. Both Glide and Picasso allow you to load images from file paths, content Uris, resources, assets, and more. See Glide's RequestManager class for all of the available types Glide currently supports. Don't re-invent the wheel, use a library....
How to divide the L2 cache between the cores on a ARM Cortex-A7?

Are CDNs that don't cache useful?

Hibernate Query cache invalidation

The query cache is not useful for write-mostly applications, as you probably figured out yourself. There is no write-through query caching option, so you need to question why you are using this feature in the first place. The entity caching is useful when you plan on changing those entities you’re...

Why does the expiration date of the request cache lie in the past?
If the Expires header is set to 0, the browser interprets it as 1 January 1970, which relates to the Unix time aka POSIX time. Because this date lies in the past, this means that the request is not cached. The Expires header is defined within RFC 7234, which includes...
