svg - Is it a good practice to enable file compression for all file types on a webserver? -

-

do think if practice make file compression on file types on webserver?

i going enable file compression on svg files reduce wait time downloading of font files , other text base file types , thinking if practice enable file compression on types of files or not.

does have bad effect on performance or something?

please let me know experience is.

after searching web hours, found these 2 resources:

http://www.ibm.com/developerworks/library/wa-httpcomp/

and

http://docs.oracle.com/cd/e24902_01/doc.91/e23435/enablecomp.htm

form first resource:

http compression, recommendation of http 1.1 protocol specification improved page download time

and second resource:

regular text , non-image content suited compression. text files can typically compressed 70% or more. compression can save significant bandwidth , enable faster browser response times. effect negligible in high speed lan environments, quite noticeable users on slow wan connections.

compression not recommended files compressed. partial list includes these types of files:

zip

pdf

exe

image files

compressing these file types using mod_deflate can increase size or corrupt files.

there 9 levels of compression available when using mod_deflate. difference between default level (6) , maximum compression level (9) minimal, , cost in cpu time necessary process higher compression level significant , not beneficial. reason, should use default compression level.

so here list prefer compress on server side:

*/*xml* (including application/xhtml+xml | application/xml | application/xml-dtd | image/svg+xml and...)

text/* (including text/html | text/javascript , ...)

message/* (including message/http | message/rfc822 , ...) page's code sample http://www.iis.net/configreference/system.webserver/httpcompression

application/ecmascript | application/json | application/javascript

this may useful someone.

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...
