angular-cli resolves this by providing an –output-hashing flag for the build command (versions 6/7, for later versions see here). Example usage: ng build –output-hashing=all Bundling & Tree-Shaking provides some details and context. Running ng help build, documents the flag: –output-hashing=none|all|media|bundles (String) Define the output filename cache-busting hashing mode. aliases: -oh <value>, –outputHashing <value> Although this … Read more
There is a common pattern that solves this problem quite well. Use sorted sets, and use a timestamp as the score. It’s then trivial to delete items by score range, which could be done periodically, or only on every write, with reads always ignoring the out of range elements, by reading only a range of … Read more
Memoization is a specific form of caching that involves caching the return value of a function based on its parameters. Caching is a more general term; for example, HTTP caching is caching but not memoization. Wikipedia says: Although related to caching, memoization refers to a specific case of this optimization, distinguishing it from forms of … Read more
The benefit of write-through to main memory is that it simplifies the design of the computer system. With write-through, the main memory always has an up-to-date copy of the line. So when a read is done, main memory can always reply with the requested data. If write-back is used, sometimes the up-to-date data is in … Read more
The cache is there to reduce the number of times the CPU would stall waiting for a memory request to be fulfilled (avoiding the memory latency), and as a second effect, possibly to reduce the overall amount of data that needs to be transfered (preserving memory bandwidth). Techniques for avoiding suffering from memory fetch latency … Read more
I noticed it myself, and found the files inside the backup folder. You can check where it is using Menu:Settings -> Preferences -> Backup. Note : My NPP installation is portable, and on Windows, so YMMV.
Redis is a remote data structure server. It is certainly slower than just storing the data in local memory (since it involves socket roundtrips to fetch/store the data). However, it also brings some interesting properties: Redis can be accessed by all the processes of your applications, possibly running on several nodes (something local memory cannot … Read more
For Development you can also deactivate the browser cache – In Chrome Dev Tools on the bottom right click on the gear and tick the option Disable cache (while DevTools is open) Update: In Firefox there is the same option in Debugger -> Settings -> Advanced Section (checked for Version 33) Update 2: Although this … Read more
I believe that must-revalidate means : Once the cache expires, refuse to return stale responses to the user even if they say that stale responses are acceptable. Whereas no-cache implies : must-revalidate plus the fact the response becomes stale right away. If a response is cacheable for 10 seconds, then must-revalidate kicks in after 10 … Read more
No, Redis is much more than a cache. Like a Cache, Redis stores key=value pairs. But unlike a cache, Redis lets you operate on the values. There are 5 data types in Redis – Strings, Sets, Hash, Lists and Sorted Sets. Each data type exposes various operations. The best way to understand Redis is to … Read more
