code

i have tried keep wkhtmltopdf file in zip package , upload returns same error.

is possible aws lambda? have tried out ec2 instance , works fine.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
