问题 I was trying to implement simple authentication in R that would store credentials outside of the source code under revision control. I'm aware of the approach using options() and getOption() , but using it would force me to remove project-level .Rprofile from revision control. I prefer to use another approach, based on exporting credentials' environment variables via .bashrc of an R-associated Linux user ( ruser ) and then reading these credentials in project-specific .Rprofile into global

问题 I'm in the process of migrating a 2010 RoR app to Sails.js. From the face of it Sails.js looks like the best framework for migrating the app to Node.js platform. In the process, I came across a limitation - it seems like sails only caters to a development environment through local.js and a production environment. Under RoR, I had a environments folder under config, which contained dev, test, staging, production, etc. ruby files that contained constants, logging levels, etc. defined for that

问题 Some people say that their path is too long, However, the problem is often caused by recurring call of the same batch script with code like set mypath=%mypath%;appendix . People just do not realize that. I proposed a solution to restore the env variables upon exit set old_path=classpath set classpath=%classpath%;appendix java myApp set classpath=old_path But it is tedious and error prone. I may easily forget to recover or fail due to exception, another exit path. Can this be done
