Jenv is great, but the JDKs have to be manually installed. If you need more than just a couple of them, you'll want to be able to install them via command line, and sdkman provides this capability very cleanly for java. So... is it possible to work with both sdkman and jenv? Yes and no. Some tricks will allow you to tell jenv about the java versions that are managed by sdkman, but setting defaults (using jenv local 17.0 for instance) does not work very well. Time for a cleaner solution. Sdkman provides all of the same functionality, with more power and a slightly different (but equally simple) syntax. I've switched from jenv to sdkman. Here's my cheat sheet.
Download and install sdkman. Follow the required instructions after installing. Then, run the config command to enable auto_env support.
echo “Installing SDKMAN"
curl -s https://get.sdkman.io | bash

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.
This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea

| the best way (I've found) to completely uninstall node + npm is to do the following: | |
| go to /usr/local/lib and delete any node and node_modules | |
| go to /usr/local/include and delete any node and node_modules directory | |
| if you installed with brew install node, then run brew uninstall node in your terminal | |
| check your Home directory for any local or lib or include folders, and delete any node or node_modules from there | |
| go to /usr/local/bin and delete any node executable | |
| You may need to do the additional instructions as well: | |
| sudo rm /usr/local/bin/npm |

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
