ūüôŹ This is an open-source project. Star this repository, if you like it, or even donate to maintain the servers and the development. Thank you so much!

Possible, this mini server, rarely, is down, please hang on for 15-30 minutes and the server will be back up.

All my domains (patrikx3.com and corifeus.com) could have minor errors, since I am developing in my free time. However, it is usually stable.

IntelliJ Speed

Based on: http://sheroz.com/pages/blog/improving-development-performance-moving-intellij-idea-cache-ramdisk.html

After all these tricks I tried to open my current project with IntelliJ IDEA 12 … 
 
Wow!!! It is fantastic! Works like a … sword!!! 
 
Why sword?! I don’t know exactly. May be because of Darcula theme. This is just first thought what came to my mind seeing the overall results. 
 
The Intellij IDEA 12 now works as a lightsaber sword, as a weapon of a Jedi Knight, which you can trust in Java world! 

Features

  • Requires tmpfs, bash, fstab, rsync, memory :)

  • SystemD

    • Service
    • Timer
    • Suspend
    • RAM disk to HDD
  • Linux for sure, easy to extend for Unix, BSD, macOS

    • Should might need some tuning, but the functions are there, I just only tested in Linux.

Intel Optane

I think my ramdisk is faster. :) Ciao!!!

Use case

Speed up IntelliJ and development Node. (Tons of files.)
The result is that the development is many folds faster. No waiting at all.

Do not use the $USER variable, use the actual username, like p3x-robot.

So actual install

patrikx3@workstation ~ $ p3x-ramdisk install --help
 
  Usage: install [options] <uid>
 
  
Install a p3x-ramdisk    
 
 
  Options:
 
    -h, --help               output usage information
    -r, --rampath [path]     The path of the ram disk, default /home/$USER/ramdisk
    -p, --persistent [path]  The path of the ram persistent, default /home/$USER/ramdisk-persistent
    -g, --gid [group]        The gid, it you omit it is the current user
    -t, --timer [minutes]    The timer in minutes, minimum about 10 minutes, Default is 20 minutes, the best
    -s, --size [megabytes]   Ramdisk in size of megabytes, default is 4096 megabytes

IMPORTANT

Trash is disabled in GNOME with p3x-ramdisk. It will ask for confirm to delete data. You might have it in the previous save. It is possible to enable trash bin, but for me is not important now, so I disabled, memory is not cheap.

Setup

Use GitHub for info, NPM hides wide strings.

https://github.com/patrikx3/ramdisk

# of course your data will never be deleted, 
# double persistence (current, previouse, saves every 20 minutes) 
# load on boot, plus at shutdown and suspend it saves 
 
sudo npm install -g p3x-ramdisk --unsafe-perm=true --allow-root
 
# install 
# if you need less/more memory, add -s 1024 or even more, 10GB is good :) 
sudo p3x-ramdisk install $USER    
 
# Get the output, add to /etc/fstab

sudo mount -a
# you should verify the ramdisk is existing now, you might have to reboot 
# on linux it can show your settings, like below: 
df -h
 
# if there is an error, you can  
sudo p3x-ramdisk stop $USER
 
# if all good 
# STARTUP THE RAMDISK PERSISTENT 
sudo p3x-ramdisk start $USER
 
# you can work like here (this a symlink, so you can't accidentally delete 
# so next time boot, it will re-create the symlink ...)

# to trigger a savs 
p3x-ramdisk save $USER
 
# you don't need usually to save 
# the default is 20 minutes 
# the systemd service saves on suspend and shutdown 
 
 
# to stop the services 
# removes sync, so the ramdisk files will be unavailable, 
# only be in /home/username/ramdisk-persistent/current

# your duplicate copies are 
ls -all /home/$USER/ramdisk-persistent/current/
ls -all /home/$USER/ramdisk-persistent/previous/
 
# you are done 
# the default use case is to speed up working with IntelliJ and my projects to ramdisk 
# if you just want persistent folder and that's all 
# there is a special folder, .p3x-ramdisk-link 
# everything there is linked into /home/$USER 
# if there is nothing in .p3x-ramdisk-link 
# no linking is. to test it, you might not need it.
