the basic difference in approach was to switch the earlier approach of if (conditionA && conditionB && !conditionC) cache_it() to hey look, an item with featureset X is cacheable while one with featureset Y is not. This refl

To add to Vlad's comment above: The major win was in being able to create a simple API which inherently computes update -> cache invalidation probability taking into account the semantics of the item being cached and its relevance t

Thanks! Working on the timeline feature. The temporal data and diet/size tags need some clean up - a tedious work via an offline tool with RegEx and some nltk elbow grease :)

now i remember why I went with the old linked list implementation. with the std::list, everytime I refreshed a node... i did a copy. basically to the tune of list.push_back(*iter) where as I wanted to keep it as a simple unlink and relink o

ah, now I remember why I had carried on with the linked list from the old c++ codebase https://gist.github.com/Quinny/09e34afb1d187e43dea2f3c3b0c04... the key refresh in std::list required a copy of the std::pair, wher

thanks. fixed

yeah, saw the gist posted by quinnftw. that actually is a better way to do what I'm doing. Will update that along with the cache.remove(const Key& k, F deleteCallback) method. Thanks for the feedback

the naked pointers are inside an internal kv namespace and are a convenience/carry over from the previous implementation (I've covered the justification for the way it's written in a comment above). the TL;DR is that it is wr

by mohaps 10y ago
the kv::List is not intended as a generic linked list implementation like std::list. The reason for the specific implementation is to get constant time removal and remove-add_to_end operations. Truth be told, it is a hold-over from the prev

mostly: yes! :) Also, keep in mind that most of the library is templates, which need to go in the header files. BTW, most of boost is header-only :) e.g. boost/noncopyable.hpp would give you a header only equivalent of the NoCopy cla
25.
by mohaps 10y ago
header-only usually means there's one or more .h/.hpp files that you can include in your source. There's no source file or library to compile and include e.g. if I had Hello.h and Hello.cpp, you'd need to either add Hell

Good work on the lib. I think EchoSim is provided by iQuarius media and not Amazon.
