(Is it because this is Java and therefore I shouldn’t be doing evil nonportable obsolete things like touching my environment?) I think you’ve hit the nail on the head. A possible way to ease the burden would be to factor out a method and pass any ProcessBuilders through it before starting them. Also, you probably already … Read more
Whatever you do, make sure not to trust data sent from the client. $_SERVER[‘REMOTE_ADDR’] contains the real IP address of the connecting party. That is the most reliable value you can find. However, they can be behind a proxy server in which case the proxy may have set the $_SERVER[‘HTTP_X_FORWARDED_FOR’], but this value is easily spoofed. For example, … Read more
4 steps npm install dotenv –save Next add the following line to your app.require(‘dotenv’).config() Then create a .env file at the root directory of your application and add the variables to it. Finally, add .env to your .gitignore file so that Git ignores it and it never ends up on GitHub. If you are using create-react-app then you only need step 3 and … Read more
Hmmm — since this is handled by the JVM, I delved into the OpenJDK VM source code a little bit, thinking that maybe what’s done by OpenJDK mimics what’s done by Java 6 and prior. It isn’t reassuring that there’s a way to do this other than on Windows. On Windows, OpenJDK’s get_temp_directory() function makes a Win32 API … Read more
I got a new laptop with Windows 10 and I want to set it up so I can use java and javac from the command line. I have searched online but all the guides are for previous versions, and I don’t want to mess around with something I don’t understand.
One difference (observed in Python 2.7 and 3.8) between getenv() and environ[]: os.getenv() does not raise an exception, but returns None os.environ.get() similarly returns None os.environ[] raises an exception if the environmental variable does not exist
If you set LD_PRELOAD to the path of a shared object, that file will be loaded before any other library (including the C runtime, libc.so). So to run ls with your special malloc() implementation, do this:
it turns out I was mistaken. Solution is: in anaconda (as well as in other implementations), set the path environment variable to the directory where ‘python.exe’ is installed. As a default, the python.exe file in anaconda is in: after you do that, obviously, the python command works, in my case, yielding the following.
Before running your app, you can do this in console, Or if you are in windows you could try this: for PowerShell: or you can run your app like this: You can also set it in your js file: But I don’t suggest to do it in your runtime file, since it’s not easy to … Read more
Environment variables must be strings, so use to set the variable DEBUSSY to the string 1. To access this variable later, simply use: Child processes automatically inherit the environment variables of the parent process — no special action on your part is required.
