i wrote cellular automaton program stores data in matrix (an array of arrays). 300*200 matrix can achieve 60 or more iterations per second using static memory allocation (e.g. std::array ). i produce matrices of different sizes without recompiling program every time, i.e. user enters size , simulation matrix size begins. however, if use dynamic memory allocation, (e.g. std::vector ), simulation drops ~2 iterations per second. how can solve problem? 1 option i've resorted pre-allocate static array larger anticipate user select (e.g. 2000*2000), seems wasteful , still limits user choice degree. i'm wondering if can either a) allocate memory once , somehow "freeze" ordinary static array performance? b) or perform more efficient operations on std::vector ? reference, performing matrix[x][y] == 1 , matrix[x][y] = 1 operations on matrix. according this question/answer , there no difference in performance between std::vector or using pointers. edit: i...

i deploying flask app uwsgi multiple servers. different server should run same app read different config file. there 2 config file used in app. 1 'config.py' read flask: app.config.from_object('config') another 'uwsgi_config.ini' used when starting uwsgi: uwsgi uwsgi_config.ini since have several server, must write several config files like: config.dev.py config.test.py config.prod.py uwsgi_config.dev.py uwsgi_config.dev.py uwsgi_config.prod.py so question how can switch different tiers when starting uwsgi without hacking source code every time ? i think key thing should run uwsgi this: uwsgi uwsgi_config.dev.ini and flask can read 'dev' tier uwsgi_config.dev.ini. there simple way ?
