scala - Could a lazy val be tail-recursive? - 


lazy val seq: unit = {   println("a")   seq }

can call expression above tail-recursively?

i guess argue in sense, yes - when evaluated, seq recursively evaluate itself, , evaluation last action performed.

regardless of whether can called tail-recursive, though, there doesn't seem of point it. there no exit condition nor, if try , keep code purely functional, can there one: there no parameter, means there no "state" pass deeper evaluations , nothing test against break recursion.

also, if indeed tail-recursive, it's not form of tail recursion recognised or supported scala - evaluate seq , stackoverflowerror.

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...
