I run my own server with dynamic IP address so it may happen that the server can not be reachable for about max 5 minutes due to the dynamic DNS. The server may also be unreachable when I backup the SSD with Clonzilla (very rarely) or an electrical issue (but this should not happen again). When the server is down, please hang on for 5-30 minutes and the server will be back up.

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

# Breaking change ## v1.1 This is only important if you have an older version (1.0.x-y) and/or you use linked folders (like IntelliJ). It will never change anymore, but sometimes I can delete accidentally my data from the ramdisk, so I refactored the name instead of: ```text /home/user/ramdisk/persistence ``` now it is called ```text /home/user/ramdisk/.p3x-ramdisk-persistence ``` (hidden by default). If you are linked to IntelliJ for example, you have to recreate the symlink in your home. For example, migration looks like this: ```bash # exit intellij if you have linked sudo p3x-ramdisk stop

088150dd

rm -rf ~/ramdisk/persistence

3494142c

sudo npm i -g p3x-ramdisk sudo p3x-ramdisk install $USERNAME sudo p3x-ramdisk start # so you are already linked into p3x-ramdisk, here # (if you are not linked, do not delete and # do not execute below, only if the intellij # data is linked and you are sure it is a # symlink ) ll ~/.IntelliJIdea2018.1 ``` Shows: ```text lrwxrwxrwx 1 patrikx3 patrikx3 94 Apr 14 19:34 /home/patrikx3/.IntelliJIdea2018.1 -> /home/patrikx3/ramdisk/.p3x-ramdisk-persistence/content/.p3x-ramdisk-link/.IntelliJIdea2018.1/ ``` **MAKE SURE YOU EXIT FROM INTELLIJ.** If you are sure it is a link, you can recreate like: ```bash rm ~/.IntelliJIdea2018.1 ln -s ~/ramdisk/.p3x-ramdisk-persistence/content/.p3x-ramdisk-link/.IntelliJIdea2018.1/ ~ ``` Now you are safe.

## IntelliJ Speed Based on: http://sheroz.com/pages/blog/improving-development-performance-moving-intellij-idea-cache-ramdisk.html ```text 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! ```

* Requires tmpfs, bash, fstab, rsync, memory :) * Usually, all requirements of every Unix flavor are installed by default * SystemD * Service * Timer * Suspend * RAM disk to HDD

3494142c

* Linux for sure, easy to extend for Unix, BSD, macOS

a7998c18

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

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 ```bash # 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
