multithreading - Have these two java.io.File thread safety issues been evaded? -


assuming win32filesystem , beginmultithreading runs many times simultaneously on shared multithreadingclass object, possible way can cause data-race or other threading issue? know not thread safe, because (1) argument setpath gets reused. see (2) path not final variable in java.io.file. however, can't seem find part code error out on own due threading issue. 

public class multithreadingclass {     private holder h = new holder();     private string path ="c:\\somepath";      public void beginmultithreading(){         h.setpath(new file(path));         h.begin();     } }  public class holder {     private file path;     public void setpath(file path){         this.path = path;     }     public void begin(){         system.out.println(path.getcanonicalpath()+"some string");     } }

your example code has no multi-threading @ all. i'll assume either multiple threads operating on own multithreadingclass instance, or sharing common instance between them.

either way, code thread safe. shared state private string object, not adjusted part of methods.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
