windows 7 - Machine continues to freeze -

-

as of lately, desktop has been freezing @ seemingly random times under no extraneous workloads. believe issue being caused firefox, unsure , need debugging situation.

the machine has 2 hard drives; ssd partitioned dual-boot windows 7 , ubuntu 12.04, , standard hard drive partitioned hold basic windows documents (documents, desktop, downloads, etc.) , /home , /usr/local ubuntu. applications (at least windows) installed on ssd.

the freezing issue on windows 7. seems occur randomly when browsing web using firefox. unsure if due filesystem setup have desktop or possibly corrupted installation of firefox (or other?). have never had issue before (on machine). should noted never experienced issue on machine before repartitioning ssd dual-boot. if there information can provide debug situation, please let me know.

i have had problems in windows 7. used use firefox time lately seems firefox causing more , more memory issues. browsing in chrome never gives problems. had these problems when watching video`s in firefox. did (only usefeull if system 64 bit) install waterfox. firefox, build 64 bit systems (non official build).

firefox memory issues solved ever since.

also, because regularely had whole pc crash (my screen show brigh color of pink or blue , totally stop working), have installed avg pc tune up. since then, haven`t had crash anymore. see reply on question: https://stackoverflow.com/questions/28791468/windows-7-frequent-computer-crashes-blue-screen/28807578#28807578

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
