HOW TO: Install BLTOUCH V3.1 and Marlin 2.0 on Ender 3/Pro With ONLY a mini USB and the included USB ISP cable!

When I say included, I mean the USB ISP cable with the 10 to 6 pin adapter that is included with the Creality branded BLTOUCH kit. I also needed a mini USB to USB type A cable that was not included. If you are well versed in Arduino and flashing firmwares to 3d printers, this write up isn't for you. This is for the total noob (like me) that has never done anything like this before.

I just went through this process, and I could not find a single source that had all of the information I needed to get this done using *only* the hardware I had on hand. I didn't want to buy an Arduino Uno or a Raspberry Pi or anything else, and that seemed to make things harder, but really I just needed to learn a few things about how the Arduino IDE software works. This is being written from a 100% noob perspective, so feel free to correct any faults. Link to BLTOUCH I ordered on Amazon (US)
So, here we go.
First of all, you can follow the included creality manual that shows how to physically install the bltouch kit on the Ender 3/Pro. Ignore the software part, because we will be using a much better version of software called Marlin (version 2.). Once you have installed the bltouch and removed the unnecessary end stop switch, leave the motherboard exposed so you can access the 6 pin connector that you use to flash firmware. At this time your Ender 3 or 3 Pro should be turned off and unplugged-it does not need to be plugged in to the main power cable to flash the firmware.
Once you have that done and the motherboard is exposed, we can start with the needed software. First, download the firmware file for your specific printer (in my case it was Ender 3 pro BL touch +ISP cable instruction") from this website (creality3d.com). Once you do that, unzip the file to a convenient place. Then go in the included folder and un-rar the next folder called ISP.rar, then open the folder called ISP, then unzip the folder called progisp+1.72. zip. In this folder, there will be be another folder called progisp+1.72, but it will have some Chinese characters after the name. You need to rename this folder for progisp to work! Apparently the Chinese characters throw it off or something, and cause an error. So rename it progisp or whatever you want, as long as the Chinese characters are removed. We are not using the included firmware with this package, only the application that is inside your newly renamed filed, called progisp.exe. Remeber the location of this, because we will need it in a bit.
Next, we are going to setup our firmware. Go to this website (github) and click the "clone or download button on the right side of the page, then click "Download ZIP" in the dropdown. This is for Marlin 2.0 firmware that is preconfigured for the Ender 3 and Ender 3 Pro, so you don't have to do any editing in Arduino of this firmware. It makes the process (much) easier in my opinion. You can unzip the downloaded file and put it somewhere easy to access (I used my desktop for everything).
Now, we need to download the Arduino IDE software. Once installed, you can open the program and go through initial setup to get to the software. Close the software when you are at the home screen.
*********I am not sure if this step is completely necessary or not, but this is how I did it:
-Now we flash a bootloader. I used this bootloader file. If you haven't downloaded from github before (I hadn't), right click on the "RAW" button and click "save link as...", then save the file to your preferred location. It will save as a .hex file which we will flash to the motherboard. Now, you can connect the USB ISP cable that came with the bltouch kit to your Ender 3/Pro motherboard, and into your laptop. You will need the cable itself, as well as the 10 pin to 6 pin adapter board that came with the kit. The included instructions show you how to plug it in-in my case, the long gray cable from the USB ISP points away from the motherboard when plugged in correctly. It's easier to plug in if you unplug the screen cable first, which is the large cable right next to the 6 pin connector.
Now, with Arduino closed, we open the progisp.exe file that came with the Ender 3 firmware file we downloaded and unzipped,unrar'ed, and renamed. Progisp will open on your computer. In the upper left hand corner of the display, click the drop down under "select chip", and choose "ATmega1284P". Then click the "..." button in the lower right corner of the screen, and enter these values: Low Value: DC; High Value: D6; EXTValue: FD; and LockValue: FF, then click "write", and close the popup window so you are back at the progisp home screen. In the upper left corner of the screen there is a window that says "Program State"-In the box below that PRG ISP should be in color-this will let you know that the motherboard is connected properly-as well as the blue light on the motherboard. On the home screen select on these options: Chip Erase, Program FLASH, and Program Fuse. Now, in the upper right corner click "load flash", and select the .hex bootloader file we just downloaded from github, and then click the "Auto" button. A green progress bar will show, and you the message box will give you a successful message. For now, you can close progisp (but we will need it again in a moment (my understanding is that you should not run progisp and arduino at the same time, that's why I keep jumping around).
Next, we unplug the USBISP cable, and plug in a mini USB cable directly to the USB port on the front of the Ender's electronics case and into your computer. Then, we will navigate to the unzipped folder that contains the Marlin firmware. It should be called Ender-3-bltouch-installation-master. Open that, then open the next folder called Marlin 2.0-Ender 3 BLTOUCH, and now open the folder called "Marlin". Inside of it there is a file called "marlin.ino". Double click that file and it will automatically open Arduino IDE, and you will be at the firmware editor screen.
From here, go to Tools and Manage libraries and add the U8glib Library (Make sure the library is called U8glib-it was at the bottom of the list for me). Once installed go to Go to Sketch, Include Library, find and select your u8glib. Then go to File, Preferences, select "Show Verbose Output During": Compilation and Upload, and enter this URL in Additional Boards Manager URLs:
https://raw.githubusercontent.com/Lauszus/Sanguino/mastepackage_lauszus_sanguino_index.json 
Click "OK", and click Tools, Board, Board Manager, and search for "Sanguino" and install it, then close boards manager. Now, go back to tools, and select:
Board: Sanguino
Processor: ATmega1284 or ATmega1284P (16Mhz)
Port: Select the port your USB is connected to the printer with-mine only showed one port (COM3 in my case)
Programmer: AVRISP mkII
Once you have done that, click Sketch, then verify/compile. This will take a few minutes, then when it completes go to Sketch, and click "Export compiled binary". When the software says "Done Compiling" at the bottom (the logging area), you need to find the output folder for the firmware. The log will say the following:
Compiling core...
Using precompiled core
Linking everything together...
Directory line 1
Directory line 2
Directory line 3
You need to scroll horizontally on directory line 3 and the last file will be C:/Users.......marlin.ino.hex.
Navigate to that file in file explorer, and copy and paste the .hex file into a place that is easy to find (like your desktop).
Now, we can close Arduino and unplug the mini USB cable and plug the USBISP cable back into the motherboard and computer you are using, and open progisp.exe just like we did before.
Select chip again in the top left if needed, then click the "..." button again, and make sure the same values are input (DC, D6,FD,FF), and click "Write", then close the pop up. Now, select the same options as we used previously (Chip Erase, Program FLASH, and Program Fuse), and click "load flash" in the top right corner, select the marlin.ino.hex file we placed somewhere convenient, and click "Auto". When the program is done flashing, unplug the USBISP cable from the motherboard and you can plug in your printer to the power cable and power it on.
After a few seconds you should boot into the Marlin 2.0 home screen, and you can now configure your bltouch!
If following this guide helps you out, let me know! This is exactly the process I followed and I am now (finally) running Marlin 2.0 with a working BLTouch. If this is horrible, let me know that as well and maybe I can fix it! I know it's a little lengthy, but it's really not a *hard* process per se. Anyway, hope this helps someone.

Tutorial: Using Borg for backup your QNAP to other devices (Advanced - CLI only)

Tutorial: Using Borg for backup your QNAP to other devices (Advanced - CLI only)
This tutorial will explain how to use Borg Backup to perform backups. This tutorial will specifically be aimed to perform backups from our QNAP to another unit (another NAS in your LAN, external hard drive, any off-site server, etc). But it is also a great tool to backup your computers to your NAS. This tutorial is a little bit more technical than the previous, so, be patient :)
MASSIVE WALL OF TEXT AHEAD. You have been warned.
Why Borg instead of, let’s say HBS3? Well, Borg is one of the best -if not THE BEST- backup software available. It is very resilient to failure and corruption. Personally I’m in love with Borg. It is a command line based tool. That means that there is no GUI available (there are a couple of front-end created by community, though). I know that can be very intimidating at first when you are not accustomed to it, and that it looks ugly, but honestly, it is not so complicated, and if you are willing to give it a try, I can assure you that is simple and easy. You might even like it over time!
https://www.borgbackup.org/
That aside, I have found that HBS3 can only perform incremental backups when doing QNAP-QNAP backups. It can use Rsync to save files to a non-QNAP device, but then you can’t use incremental (and IIRC, neither Deduplication or encryption). It will even refuse to save to a mounted folder using hybrid mount. QNAP seems to be trying to subtle lock you down in their ecosystem. Borg has none of those limitations.

Main pros of Borg Backup:
- VERY efficient and powerful
- Space efficient thanks to deduplication and compression
- Allows encryption, deduplication, incremental, compression… you name it.
- Available in almost any OS (except Windows) and thanks to Docker, even in Windows. There are also ARM binaries, so it is Raspberry compatible, and even ARM based QNAPs that don’t support docker can use it!!!
- Since it’s available in most OS, you can use a single unified solution for all your backups.
- Can make backups in PUSH and PULL style. Either each machine with Borg pushes the files into the server, or a single server with Borg installed pulls the files from any device without needing to install Borg on those devices.
- It is backed by a huge community with tons of integration and wrapper tools (https://github.com/borgbackup/community)
- Supports Backup to local folders, LAN backups using NFS or SMB, and also remote backups using SFTP or mounting SSHFS.
- IT IS FOSS. Seriously, guys, whenever possible, choose FOSS.

Cons of Borg Backup:
- It is not tailored for backups to cloud services like Drive or Mega. You might want to take a look at Rclone or Restic for that.
- It lacks GUI, so everything is CLI controlled. I know, it can be very intimidating, but once you have used it for a couple of days, you will notice how simple and comfortable to use is.

The easiest way to run Borg is to just grab the appropriate prebuilt binary (https://github.com/borgbackup/borg/releases) and run it baremetal, but I’m going to show how to install Borg in a docker container so you can apply this solution to any other scenario where docker is available. If you want to skip the container creation, just proceed directly to step number 2.

**FIRST STEP: LET'S BUILD THE CONTAINER**
There is currently no official Borg prebuilt container (although there are non-official ones). Since it’s a CLI tool, you don’t really need a prebuilt container, you can just use your preferred one (Ubuntu, Debian, Alpine etc) and install Borg directly in your container. We are using a ubuntu:latest container because the available Borg version for ubuntu is up to date. For easiness, all those directories we want to backup will be mounted inside the container in /output.
If you already are familiar with SSH and container creation though CLI, just user this template, substituting your specific directories mount.
docker run -it \ --cap-add=NET_ADMIN \ --net=bridge \ --privileged \ --cap-add SYS_ADMIN \ --device /dev/fuse \ --security-opt apparmor:unconfined \ --name=borgbackup \ -v /share/Movies:/output/Movies:ro \ -v /share/Important/Documents:/output/Documents:ro \ -v /share/Other:/output/Other:ro \ -v /share/Containeborgbackup/persist:/persist \ -v /etc/localtime:/etc/localtime:ro \ ubuntu:latest 
(REMEMBER: LINUX IS CAPITAL SENSIBLE, SO CAPITALS MATTER!!)
Directories to be backup are mounted as read only (:ro) for extra safety. I have also found that mounting another directory as “persistent” directory makes easy to create and edit the needed scripts directly from File Finder in QNAP, and also allows to keep them in case you need to destroy or recreate the container: this is the “/persist” directory. Use your favorite path.
If you are not familiar with SSH, first go here to learn how to activate and login into your QNAP using SSH (https://www.qnap.com/en/how-to/knowledge-base/article/how-to-access-qnap-nas-by-ssh/).
You can also use the GUI in Container Station to create the container and mount folders in advanced tab during container creation. Please, refer to QNAP’s tutorials about Docker.
GUI example
If done correctly, you will see that this container appears in the overview tab of Container Station. Click the name, and then click the two arrows. That will transport you to another tab inside the container to start working.

**SECOND STEP: INSTALLING BORG BACKUP INSIDE THE CONTAINER**
First check that the directory with all the data you want to backup (/output in our example) is mounted. If you can’t see anything, then you did something wrong in the first step when creating the container. If so, delete the container and try again. Now navigate to /persist using “cd /persist”
See how /output contains to-be-backup directories
Now, we are going to update ubuntu and install some dependencies and apps we need to work. Copy and paste this:
apt update && apt upgrade -y apt install -y nano fuse software-properties-common nfs-common ssh 
It will install a lot of things. Just let it work. When finished, install borgbackup using
add-apt-repository -y ppa:costamagnagianfranco/borgbackup apt install -y borgbackup 
When it’s finished, run “borg --version” and you will be shown the current installed version (at time of writing this current latest is 1.1.10). You already have Borg installed!!!!
1.1.10 is latest version at the time of this tutorial creation

**THIRD STEP: PREPARING THE BACKUP DEVICE USING NFS MOUNT**
Now, to init the repository, we first need to choose where we want to make the backup. Borg can easily make “local” backups, choosing a local folder, but that defeats the purpose for backups, right? We want to create remote repositories.
If you are making backups to a local (same network) device (another NAS, a computer, etc) then you can choose to use SFTP (SSH file transfer) or just NFS or SMB to mount a folder. If you want to backup to a remote repository outside your LAN (the internet) you HAVE to use SFTP or SSHFS. I’m explaining now how to mount folder using NFS, leaving SFTP for later.
Borg can work in two different ways: PUSH style or PULL style.
In PUSH style, each unit to be backup have Borg installed and it “pushes” the files to a remote folder using NFS, SMB or SSHFS. The target unit do not need to have Borg installed.
PUSH style backup: The QNAP sends files to the backup device

In PULL style, the target unit that is going to receive the backups has Borg installed, and it “pulls” the files from the units to be backup (and so, they don’t need Borg installed) using NFS, SMB or SSHFS. This is great if you have a powerful NAS unit and want to backup several computers.
PULL style backup: The backup device gets files from QNAP. Useful for multiple unit backups into the same backup server.

When using SFTP, the backup unit has Borg installed, opens a secure SSH connection to target unit, connects with Borg in target machine, and uploads the files. In SFTP style, BOTH units need Borg installed.
SFTP: Borg needs to be installed in both devices, and they \"talk\" each other.

I’m assuming you have another device with IP “192.168.1.200” (in my example I’m using a VM with that IP) with a folder called “/backup” inside. I’m also assuming that you have correctly authorized NFS mount with read/write permissions between both devices. If you don’t now how to, you’ll need to investigate. (https://www.qnap.com/en-us/how-to/knowledge-base/article/how-to-enable-and-setup-host-access-for-nfs-connection/)
NFS mount means mirroring two folders from two different devices. So, mounting folder B from device Y into folder A from device X means that even if the folder B is “physically” stored on device Y, the device X can use it exactly as if it was folder A inside his local path. If you write something to folder A, folder B will automatically be updated with that new file and vice-versa.
Graphical example of what happens when mounting folders in Linux system.
Mount usage is: “mount [protocol] [targetIP]:/target/directory /local/directory” So, go to your container and write:
mount -t nfs 192.168.1.200:/backup /mnt 
Mount is the command to mount. “-t nfs” means using NFS, if you want to use SMB you would use “-t cifs”. 192.168.1.200 is the IP of the device where you are going to make backups. /backup is the directory in the target we want to save our backups to (remember you need to correctly enable permission for NFS server sharing in the target device). /mnt is the directory in the container where the /backup folder will be mounted.
OK, so now /mnt in container = /backup in target. If you drop a .txt file in one of those directories, it will immediately appear on the other. So… All we have to do now is make a borg repository on /mnt and wildly start making backups. /mnt will be our working directory.

**FOURTH STEP: ACTUALLY USING BORG** (congrats if you made it here)
Read the documentation
https://borgbackup.readthedocs.io/en/stable/usage/general.html
It’s madness. Right?. It’s OK. In fact we only need a very few borg commands to make it work.
“borg init” creates a repository, that is, a place where the backup files are stored.
“borg create” makes a backup
“borg check” checks backup integrity
“borg prune” prunes the backup (deletes older files)
“borg extract” extract files from a backup
“borg mount” mounts a backup as if it was a directory and you can navigate it
“borg info” gives you info from the repository
“borg list” shows every backup inside the repository
But since we are later using pre-made scripts for backup, you will only need to actually use “init”, “info” and “list” and in case of recovery, “mount”.
let’s create our repository using INIT
https://borgbackup.readthedocs.io/en/stable/usage/init.html
borg init -e [encryption] [options] /mnt 
So, if you want to encrypt the repository with a password (highly recommended) use “-e repokey” or “-e repokey-blake2”. If you want to use a keyfile instead, use “-e keyfile”. If you don’t want to encrypt, use “-e none”. If you want to set a maximum space quota, use “--storage-quota ” to avoid excessive storage usage (I.e “--storage-quota 500G” or “--storage-quota 2.5T”). Read the link above. OK, so in this example:
borg init -e repokey –storage-quota 200G /mnt 
You will be asked for a password. Keep this password safe. If you lose it, you lose your backups!!!! Once finished, we have our repository ready to create the first backup. If you use “ls /mnt” you will see than the /mnt directory is no longer empty, but contains several files. Those are the repository files, and now should also be present in your backup device.
init performed successfully
Let’s talk about actually creating backups. Usually, you would create a backup using the “borg create” backup command, using something like this:
borg create -l -s /mnt::Backup01 /output --exclude ‘*.py’ 
https://borgbackup.readthedocs.io/en/stable/usage/create.html
That would create a backup archive called “backup01” of all files and directories in /output, but excluding every .py file. It will also verbose all files (-l) and stats (-s) during the process. If you later write the same but with “Backup02”, only new added files will be saved (incremental) but deleted files will still be available in “Backup01”. So as new backups are made, you will end running out of storage space. To avoid this you would need to schedule pruning.
https://borgbackup.readthedocs.io/en/stable/usage/prune.html
borg prune [options] [path/to/repo] is used to delete old backups based on your specified options (I.e “save 4 last year backups, 1 backups each month last year, and 1 daily last month).
BUT. To make is simple, we just need to create a script that will automatically 1) Create a new backup with specified name and 2) run a Prune with specified retention policy.
Inside the container head to /persist using “cd /persist”, and create a file called backup.sh using
touch backup.sh chmod 700 backup.sh nano backup.sh 
Then, copy the following and paste it inside nano using CTRL+V
#!/bin/sh # Setting this, so the repo does not need to be given on the command line: export BORG_REPO=/mnt # Setting this, so you won't be asked for your repository passphrase: export BORG_PASSPHRASE='YOURsecurePASS' # or this to ask an external program to supply the passphrase: # export BORG_PASSCOMMAND='pass show backup' # some helpers and error handling: info() { printf "\n%s %s\n\n" "$( date )" "$*" >&2; } trap 'echo $( date ) Backup interrupted >&2; exit 2' INT TERM info "Starting backup" # Backup the most important directories into an archive named after # the machine this script is currently running on: borg create \ --verbose \ --filter AME \ --list \ --stats \ --show-rc \ --compression lz4 \ --exclude-caches \ --exclude '*@Recycle/*' \ --exclude '*@Recently-Snapshot/*' \ --exclude '*[email protected]__thumb/*' \ \ ::'QNAP-{now}' \ /output \ backup_exit=$? info "Pruning repository" # Use the `prune` subcommand to maintain 7 daily, 4 weekly and 6 monthly # archives of THIS machine. The 'QNAP-' prefix is very important to # limit prune's operation to this machine's archives and not apply to # other machines' archives also: borg prune \ --list \ --prefix 'QNAP-' \ --show-rc \ --keep-daily 7 \ --keep-weekly 4 \ --keep-monthly 6 \ prune_exit=$? # use highest exit code as global exit code global_exit=$(( backup_exit > prune_exit ? backup_exit : prune_exit )) if [ ${global_exit} -eq 0 ]; then info "Backup and Prune finished successfully" elif [ ${global_exit} -eq 1 ]; then info "Backup and/or Prune finished with warnings" else info "Backup and/or Prune finished with errors" fi exit ${global_exit} 
This script seems very complicated, but all it does is
  1. Define the backup location
  2. Define backup parameters, inclusions and exclusions and run backup
  3. Define pruning policy and run prune
  4. Show stats
You can freely modify it using the options you need (they are described in the documentation).
“export BORG_REPO=/mnt” is where the repository is located.
“export BORG_PASSPHRASE='YOURsecurePASS' is your repository password (between the single quotes)
After “borg create” some options are defined, like compression, file listing and stat showing. Then exclusion are defined (each –exclude defines one exclusion rules. In this example I have defined rules to avoid backup thumbnails, recycle bin files, and snapshots). If you wish to exclude mode directories or files, you do it adding a new rule there.
::'QNAP-{now}' defines how backups will be named. Right now they will be named as QNAP-”current date and time”. In case you want only current date and not time used, you can use instead:
::'QNAP-{now:%Y-%m-%d}' \
Be aware that if you decide to do so, you will only be able to create a single backup each day, as subsequent backups the same day will fail, since Borg will find another backup with same name and skip the current one.
/output below is the directory to be backup.
And finally, prune policy is at the end. This defines what backups will be kept and which ones will be deleted. Current defined policy is to keep 7 end of day, then 4 end of week and 6 end of month backups. Extra backups will be deleted. You can modify this depending on your needs. Follow the documentation for extra information and examples.
https://borgbackup.readthedocs.io/en/stable/usage/prune.html
Now save the script using CTRL+O. We are ready. Run the script using:
./backup.sh
It will show progress, including what files are being saved. After finishing, it will return backup name (in this example “QNAP-2020-01-26T01:05:36“ is the name of the backup archive), stats and will return two rc status, one for the backup, and another for pruning. “rc0” means success. “rc1” means finished, but with some errors. “rc2” means failed. You should be returned two rc0 status and the phrase “Backup and Prune finished successfully”. Congrats.
Backup completed. rc 0=good. rc 2=bad
You can use any borg command manually against your repository as needed. For example:
borg list /mnt List your current backups inside the repository borg list /mnt::QNAP-2020-01-26T01:05:36 List all archives inside this specific backup borg info /mnt List general stats of your repository borg check -v –show-rc /mnt Performs an integrity check and returns rc status (0, 1 or 2) 
All that is left is to create the final running script and the cronjob in our QNAP to automate backups. You can skip the next step, as it describes the same process but using SFTP instead of NFS, and head directly to step number Six.

**FIFTH STEP: HTE SAME AS STEP 4, BUT USING SFTP INSTEAD**
If you want to perform backups to an off-site machine, like another NAS located elsewhere, then you can’t use NFS or SMB, as they are not prepared to be used through internet and are not safe. We must use SFTP. SFTP is NOT FTP over SSL (that is FTPS). SFTP stands for Secure File Transfer Protocol, and it’s based on SSH but for file transfer. It is secure, as everything is encrypted, but expect lower speed due encryption overhead. We need to first set it up SSH on our target machine, so be sure to enable it. I also recommend to use a non standard port. In our example, we are using port 4000.
IMPORTANT NOTE: To use SFTP, borg backup must be running in the target machine. You can run it baremetal, or use a container, just as in our QNAP, but if you really can’t get borg running in the target machine, then you cannot use SFTP. There is an alternative, though: SSHFS, which is basically NFS but over SSH. With it you can securely mount a folder over internet. Read this documentation (https://www.digitalocean.com/community/tutorials/how-to-use-sshfs-to-mount-remote-file-systems-over-ssh) and go back to Third Step once you got it working. SSHFS is not covered in this tutorial.
First go to your target machine, and create a new user (in our example this will be “targetuser”)
Second we need to create SSH keys, so both the original machine and the target one can perform SSH connection without needing for a password. It also greatly increases security. In our original container run
ssh-keygen -t rsa 
When you are asked for a passphrase just press enter (no passphrase). Your keys are now stored in ~/.ssh To copy them to your target machine, use this:
ssh-copy-id -p 4000 [email protected] 
If that don’t work, this is an alternative command you can use:
cat ~/.ssh/id_rsa.pub | ssh -p 4000 [email protected] "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys" 
You will be asked for targetuser password when connecting. If you were successful, you can now SSH without password in the target machine using “ssh -p 4000 [email protected]”. Try it now. If you get to login without password prompt, you got it right. If it still asks you for password when SSH’ing, try repeating the last step or google a little about how to transfer the SSH keys to the target machine.
Now that you are logged in your target machine using SSH, install Borg backup if you didn’t previously, create the backup folder (/backup in our example) and init the repository as was shown in Third Step.
borg init -e repokey –storage-quota 200G /backup 
Once the repository is initiated, you can exit SSH using “exit” command. And you will be back in your container. You know what comes next.
cd /persist touch backup.sh chmod 700 backup.sh nano backup.sh 
Now paste this inside:

CTRL+O to save, and CTRL+X to exit. OK, let’s do it.
./backup.sh 
It should correctly connect and perform your backup. Note that the only thing I modified from the script shown in Fourth Step is the “BORG_REPO” line, which I substituted from local “/mnt” to remote SSH with our target machine and user data.
Finally all that is left is to automate this.

**SIXTH STEP: AUTOMATING BACKUP**
The only problem is that containers can’t retain mount when they reboot. That is not problem if you are using SFTP, but in case of NFS, we need to re-mount each time the container is started, and fstab does not work in container. The easiest solution is create a script called “start.sh”
cd /persist mkdir log touch start.sh chmod 700 start.sh nano start.sh 
and inside just paste this:
#!/bin/bash log=”/persist/log/borg.log” mount -t nfs 192.168.1.200:/backup /mnt /persist/backup.sh 2>> $log echo ==========FINISH========== >> $log 
Save and try it. Stop container, and start it again. If you use “ls /mnt” you will see that the repository is no longer there. That is because the mounting point unmounted when you stopped the container. Now run
/persist/start.sh 
When it’s finished, a log file will appear inside /persist/log. It contains everything borg was previously putting in the screen, and you can check it using
cat /persist/log/borg.cat 
Everything is ready. All we need to do is is create a crontab job to automate this script whenever we want. You can read here how to edit crontab in QNAP (https://wiki.qnap.com/wiki/Add_items_to_crontab). Add this line to the crontab:
0 1 * * * docker start borgbackup && docker exec borgbackup -c /bin/bash “/persist/start.sh” && docker stop borgbackup 
That will launch container each day at 1:00 am, run the start.sh script, and stop the container when finished.

**EXTRA: RECOVERING OUR DATA**
In case you need to recover your data, you can use any device with Borg installed. There are two commands you can use: borg extract and borg mount. Borg extract will extract all files inside an archive into current directory. Borg mount will mount the repository so you can navigate it, and choose specific files you want to recover, much like NFS or SMB work.
Some examples:
borg extract /mnt::QNAP-2020-01-26T01-05-36 -> Extract all files from this specific backup time point into current directory borg mount /mnt::QNAP-2020-01-26T01-05-36 /recover -> Mounts this specific backup time point inside the /recover directory so you can navigate and search files inside borg mount /mnt /recover -> Mounts all backup time points inside the /recover directory. You can navigate inside all time points and recover whatever you want borg umount /recover -> Unmounts the repository from /recover 

I know this is a somewhat complicated tutorial, and sincerely, I don’t think there will be a lot of people interested, as Borg is for advanced users. That said, I had a ton of fun using borg and creating this tutorial. I hope it can help some people. I am conscious that like 99% of this community's users do not need advanced features and would do great using HB3... But TBH, I'm writing for that 1%.
Next up: I’m trying a duplicati container that it is supposed to have GUI, so… maybe the next tutorial will be a GUI based backup tool. How knows?

NOTE: The performance tied to the desktop view and resolution are IDENTICAL to Fallout:4 vr's release for precisely the same reasons. Except, the fix will be even better! Some improvements here:

This is another edit, Thursday the 22nd "I need to qualify this" edition.

Final edit, Tuesday's coming edition, did you bring your coat?

I am a banana, interloper.
Many things have changed and you can get away with a lot more now since the fixes are fast and furious.
Here's a concise step by step guide to improve performance in no Man's Sky VR (and some things will work even without vr). Not everything will work for everyone. Some fixes may make your particular system worse performing.Rift + Intel seems to have more trouble than Ryzen + SteamVR native devices. I'm not responsible if your computer starts repeating 16's at you.
here's what is possible: Does elements look sharper to you? I'm running global HMD in 130% SS and game at 100%. Motion smoothing off. https://i.imgur.com/Jkzf7MN.png
  1. DRIVERS. Update your Nvidia and Intel and AMD Chipset & GPU drivers.
  2. Get the latest vulkan runtime: https://vulkan.lunarg.com/sdk/home#sdk/downloadConfirm/latest/windows/vulkan-runtime.exe
  3. Install NMS, hopefully on steam. Run it in desktop mode, once, and get it smooth there. You can probably max almost everything. You may need to do a thing or two in desktop mode once and a while so it's good to have set up.
  4. Opt into the experimental beta for NMS. The fixes there are huge. To play in Experimental, right-click on No Man’s Sky from the Steam library page and select “Properties”. Among the available tabs will be the “BETAS” tab. Enter “3xperimental” in the textbox and press “CHECK CODE”, and it'll let you in, then select it from the dropdown menu.
  5. in yourdrive: \steamapps\common\No Man's Sky\Binaries\ find "NMS.exe" . Right click it, and click properties. Click "compatibility" and click "change high dpi settings" click "override high dpi scaling settings" and set it to "application controlled". This removes a layer that windows puts on 3d apps now, and since the game is not in a pure "direct mode" (yet) this removes that latency and helps frame-rate. This is similar to how Elite Dangerous was on the dk2 in the early days of windows 10. This also may improve fidelity of menu items depending on your monitor.
  6. Turn off windows "game mode" by searching for the settings in the start menu. This is normally a good thing for most games but it throttles background processes it thinks are not the main game thread. No man's sky has custom threading and this lassos it, which is bad.
  7. Install SteamVR beta and Steam Client beta. No exceptions. There's a specific fix for no man's sky in the latest update.
  8. I recommend only having one other monitor active. If you have a high hz monitor, use that one.
  9. in nvidia and amd gpu control panels, force off Vsync, always, turn on "prefer maximum performance". Set "vr precomputed frames" to application controlled instead of 1, (which is for some crazy reason still the default for nvidia. Newer games override this setting, but games built "the old way" like no man's sky do not)
  10. If you're on Nvidia turn off threaded optimization "auto". Set it to off instead. They're doing this directly and there might be some kinda conflict. If it makes it worse, force it on. These settings reduce shimmer for me: https://imgur.com/a/p9ZmcDq
  11. For both Nvidia and AMD, I recommend MSI Afterburner or just AMD drivers and setting an aggressive fan curve and power limit. You don't want to be throttling down if the card warms up. Your CPU should also be staying cool. You need to be hitting turbo cores.
  12. You can now use as of the latest patch, "motion smoothing" in steamVR with no problems most of the time, so leave it on unless things seem worse. (You're on the steamvr beta like I said in step 7, right?) If you keep going above 11ms in 90hz, turn it off.
  13. Set your application specific steamvr resolution for no man's sky to 100%
  14. Turn off Advanced Supersample filtering in steamVR dev options. Do not turn on gpu profiling, it causes slowdowns.
  15. On the video tab, use manual resolution. Change your global steamvr application resolution to something like 100% for now. IF YOU CHANGE THIS, you need to restart No Man's Sky to see the changes. It DOES NOT work on the fly like other games. I get away with 130-150% with a 1080ti and Ryzen 2700x.
  16. Go to C:\Program Files (x86)\Steam\steamapps\common\No Man's Sky\Binaries\SETTINGS and edit TKGRAPHICSSETTINGS.VR.MXML and TKGRAPHICSSETTINGS.mxml and set numhighthreads 4 and numlowthreads 2. Big improvement on the cpu side. Try 2 and 1 if you have a quad core. If you're on intel and things still suck, try 0h 0l. 0/0 may prevent you from leaving the starfield at the beginning of the game. If that happens, just set it back.
  17. Okay, go ahead and and load the game now. This imgur link has my in game settings, I recommend using these. Don't use TXAA unless you find it "clearer" It's a blurry mess for me, use FXAA. https://imgur.com/a/NkUSrMd I can also get away with hbao standard, but maybe you can't. These are something you can fiddle with, everything but planetary will work without restarting the game. I also recommend turning off vignette and scanline effects in some of the other setting menus.
  18. The game now must remain in focus. It cannot have anything on top of it or not be the active window, or you'll lag. OVR Toolkit/OvrDrop might give you issues.
  19. Optional: you should be good with the above, but you can try turning off HPET (high performance event timer) in your UEFI(bios) which can help cpu bound applications like this one.

-------------------Everything below this line is the old thread with various things I've tried. This gigantic thread is me just dumping my brain on the page with various things I know work based on years of knowledge on how VR can be tweaked, generally. Feel free to read it, but my mind tends to redline the troubleshooting but this thread spins the tires, if you know what I mean-------
happy friday! 8-16-2019:
Things have changed since the last beta patch. I'm testing on a stormy planet with lots going on right next to activity on the map to make sure settings are valid. I'll provide more screenshots.

**The app now needs to stay in focus for the best performance. It needs to be on top. Nothing else can be on top. Disable overlays if you're using them, like ovrdrop or ovr toolkit.*\*
0.5) DISABLE GAME MODE IN WINDOWS 10. You can find it in the start menu by typing "game mode". Mine was already off and I didn't realize you guys might need to know that! - This is universally good for vr since it uses a lot of background processes, I've found. as always, if you find it worse turn it back on.
  1. you should still do the cpu changes in the config files (try 4high and 2low if the game doesn't load fast)
  2. still do the "high dpi" override on NMS.exe
  3. still do the nvidia control panel overrides for NMS.exe, but I'm adding new two: turn off threaded optimization "auto". Set it to off instead. They're doing this directly and there might be some kinda conflict. If it makes it worse, force it on. These settings reduce shimmer for me: https://imgur.com/a/p9ZmcDq
  4. Set the in game framerate on the video tab to UNDER your desktop HZ but over your hmd if you have gsync/144 hz adaptive sync, or max it. I just set mine to 160 now. Consider playing with your adaptive sync/gsync settings.
  5. I recommend turning on fxaa now, either in control panel or in the game. Both work. Leave TXAA off unless you find it sharpeclearer. It's blurry for most people.
  6. Anistropy 16x all day every day. Yay.
  7. HBAO standard looks great too, no real noticeable difference in perf for me
  8. making sure no man's sky is set to 100% application render scale in steam vr, but you can now set the global video setting to auto or like 120% or more. Motion smoothing still off. You can leave interleaved re-projection on if you want, it doesn't kick in as much now, or just force it off as before if you're on amd.
  9. https://imgur.com/a/NkUSrMd here's my in game settings now, storm rolling in, getting 9.6ms frame timing. Use Fullscreen True.here's what it looks like now- my frame timing graph. I put the screenshot on a delay so that the game would be in focus for a bit, everything to the right of the red line is valid: https://imgur.com/NE6oqvX and here's with some MAJOR edits to the resolution to match the vive. Does elements look sharper to you? I'm running global HMD in 130% SS and game at 100%. Motion smoothing off. https://i.imgur.com/Jkzf7MN.png detailed advanced frame time graph. It's getting better!Oh wow, check it out: https://i.imgur.com/D55yu4S.png look at the resolution I'm using in the config file. I'm kinda blind to the visual changes now, I've been fiddling for 3 hours. You tell me which looks better, but the second one has a better frame graph.
Experimentation:Something is pretty screwy with the way the game is rendering both eyes in the HMD.
*NumGraphicsThreadsBeta value 2 completely knackers the hmd btw. Flickery mess, crash. I still don't know what it does.*I'm also going to try setting the "desktop resolution" in TKGRAPHICSSETTINGS.VR.MXML to the total resolution of the vive later on, 2160×1200, or instead a single eye, 1080×1200. This requires borderless windowed which may reduce performance over fullscreen even though it's not "fullscreen".EDIT: this seems to work at 2160x1200. At least, the game doesn't overwrite the file on me. Same 9.6ms frame timing in "windowed" The menus and other text overlay elements seem much sharper but maybe I'm fooling myself. Gonna try 1080x1200.
Of note it seems that using fullscreen gives the game higher windows application priority.Edit: Here's some proof these settings work, 1080ti, ryzen 2700x, x470 chipset, 32gb 3200mhz ddr4 cas 16, windows 10 1903 insider "fixes/drivers" only.
https://imgur.com/a/rh7ceyb
This is not a unity or unreal app and uses a -native- implementations of OpenVOVRuntime. (and on Vulkan to boot! It's amazing!) The perspective is that hello games has their own game engine, so they don't get the plug and play drag and drop implementation and bug fixes that come with the developer supported plugins for those game engines.
Serious Sam Fusion and Talos Principal are the only other games I know of that work in Vulkan/DX12 and simultaneously steamVR with a native implementation. This is an accomplishment.
The performance is due twofold to differences in 3d on earlier builds of windows 10 differing in the way it handles 3d now, your desktop resolution, your desktop monitor's HZ, and a few other things. Remember this game is fast enough to run on intel embedded graphics now. It just needs tweaking. For one, it appears the Anti-aliasing is done via forward rendering, and instead-computed on the desktop view at the desktop framerate BEFORE pushed to the hmd, along with anistropy which I suspect is why it's blurry, the "pixels" are being effectively smeared out. It's not appearing to be applied directly to the vr compositor view, or there some in between step.
Also, please opt into the experimental beta branch via the password, and consider installing the update to Vulkan via the runtime, just to make sure you're on the current version!! https://vulkan.lunarg.com/sdk/home#sdk/downloadConfirm/latest/windows/vulkan-runtime.exe update your drivers, including chipset!
First, all of this is being done from their experimental fixes branch: To play in Experimental, right-click on No Man’s Sky from the Steam library page and select “Properties”. Among the available tabs will be the “BETAS” tab. Enter “3xperimental” in the textbox and press “CHECK CODE”, and it'll let you in, then select it from the dropdown menu.
Do the following and the game will look better than ever, and you'll get 90hz and stay out of re-projection 99% of the time. The steps are similar to the early days of FO:4.go to C:\Program Files (x86)\Steam\steamapps\common\No Man's Sky\Binaries\SETTINGS and edit TKGRAPHICSSETTINGS.VR.MXML and TKGRAPHICSSETTINGS.mxml and set numhighthreads 8 and numlowthreads 0. Big improvement on the cpu side. Try 4 and 2 if the game doesn't load.
  1. in nvidia and amd gpu control panels, force off Vsync, turn on "prefer maximum performance". Set "vr precomputed frames" to application controlled instead of 1, which is the default for nvidia. For newer games this setting does nothing, but I can confirm this game DOES listen to this (like it does/did in fo4) and it breaks re-projection. In windows, I recommend only having one monitor active especially if they have different refresh rates and/or resolutions, make sure it's set to it's maximum refresh rate. I also recommend maxing your fans so your video card doesn't go into a lower boosted state and flap between them.
  2. yourdrive \steamapps\common\No Man's Sky\Binaries\ find "NMS.exe" . Right click it, and click properties. Click "compatibility" and click "change high dpi settings" click "override high dpi scaling settings" and set it to "application controlled". This removes a layer that windows puts on 3d apps now, and since the game is not in a pure "direct mode" (yet) this removes that latency and helps framerate. This is similar to how Elite Dangerous was on the dk2 in the early days of windows 10.
  3. adjust the in-game framerate limit to be 5-10fps above your HMD's, to allow re-projection to do it's thing. Edit: you can try setting this EVEN HIGHER if you think your system can handle it. This gives less overhead for re-projection, and decreases input delay, but YMMV. It's part of the reason that most people don't see 100% gpu usage, truth be told the game is gimping itself to your display's framerate cap, not the hmd for any post processing done on the desktop view before being sent to you.
  4. Go into the game's Video settings: Switch the game to fullscreen (it won't do anything visually but might as well), and consider reducing or increasing the resolution here. Edit for clarity: This does not change the resolution in the hmd, but it might be fiddling with AA and post processing's resolution, since it seems to be calculated like that, based on what I'm seeing. If you recall, FO4:VR had the same exact issue, everything was blurry as hell on launch day. EDIT: GET THIS, The lowered desktop resolution also seems to effect some things in the UI as they calculate off the lower resolution at the desktop resolution! Not the headset rendered resolution, which is really not good and super weird! It makes the scanner UI flicker and get bizarre and jumpy, which is a big problem! This is confirming my theory. I now think setting the desktop resolution higher is even more important. Get it just over your HMD resolution and leave it there. There's issues if your monitor refresh rate and resolution is below your HMD refresh rate, just like fo4vr. It does seem like the resolution is per-eye, even though it should be full-field. The vives per-eye resolution is 1080x1200, but you can't select that resolution so just set it close to that (or higher if you want SS on top of your SS for at least UI elements in game in steamvr. 1080p is fine for me. You could try making a custom virtual super resolution that matches your HMD if you're feeling industrious.
  5. under graphics, turn off all antialiasing and potentially anisitropy since it appears it's calculated from the -desktop resolution- (unless you're going beyond it for double SS, and even then, it looks better off imho. You can leave everything else on ultra at this point except maybe shadows I've found, with most GPUS, even like a rx480 8gb because Vulkan is awesome.
  6. ninja EDIT: I've determined the below is more important than I thought for performance. No longer optional!
  7. Since this is a native openVR app, if you click on the game window while it's running and press "shift+a" it SHOULD disable interleaved re-projection, which seems to be on as a fallback if you disabled motion smoothing. This helps cpu usage a TON. You can also do this with the native steamVR vr view window for most apps.
  8. finally, turn off advanced super-sampling filtering in steamvr if you're not already out of re-projection by this point. Set manual resolution settings in steamvr, and start reducing from 200% SS until the latency graph on the bottom left is under 11ms or whatever it is for your HMD and you get out of re-projection. That should solve it! and the game will run like it should and look great too. Now that I'm home, I realized something: You have to restart the game entirely for this change to work!! This could be due to the older OpenVR SDK.
  9. TURN OFF AA and do it on your gpu's control panel and turn off scanlines and post processing to get rid of the shimmer. That seems to be done on the DESKTOP resolution and not the game.
  10. DOUBLE CHECK THAT THE APPLICATION RESOLUTION OF NMS is where you want it. You may have overrode it from the global setting.
optional:
try turning off ASW if you're on a rift (can you even do that anymore?)
in your steamvr.vrsettings file in your root steam install directory also try adding "allowAsyncReprojection" : false, (comma is important unless it's the last entry) as one of the options. They pulled it. I use the following:
},
"steamvr" : {
"allowDisplayLockedMode" : false,
"allowSupersampleFiltering" : false,
"basestationPowerManagement" : 1,
"enableHomeApp" : false,
"installID" : "18309934490580095554",
"lastVersionNotice" : "1.7.4",
"lastVersionNoticeDate" : "1565657139",
"mirrorViewEye" : 3,
"motionSmoothing" : false,
"supersampleManualOverride" : true,
"allowAsyncReprojection" : false,
"supersampleScale" : 1.2
},
enjoy! if you made it this far, awesome. I haven't even dug into the game's config files, I'm reading that you can improve threaded optimization in the same way so that the cpu load is good too.
edit: here's how to do that - go to C:\Program Files (x86)\Steam\steamapps\common\No Man's Sky\Binaries\SETTINGS and edit TKGRAPHICSSETTINGS.VR.MXML and TKGRAPHICSSETTINGS.mxml and set numhighthreads 8 and numlowthreads 0. Big improvement.
also, a new setting has appeared called " " in the files on the beta. I have no idea what it does. yet.
Interestingly this reminds me a lot of the way NMS was first released, planet loading was timed to spinner hard disks or something and having an SSD actually made going from space to planet real fast kinda laggy. Really interesting how software development works. (It's what I do for a living, actually! I'm paid to find the reasons for, and the solution to, bugs in software ;) )
edit 2, I'm home from work edition: one very confirmed oversight right now is that they're not opting to cull the render of the nose cutout for your specific hmd. This results in roughly 20% performance loss off the top, confirmed by valve engineers. They're using an old version of the runtime.
as confirmed by Alex himself, the principal graphics software developer for steamvr at valve. https://twitter.com/AlexVlachos/status/1161871180103421952
edit 3, happy weekendhttps://imgur.com/a/p9ZmcDq this settings has reduced some shimmering for me.

MAME 0.216

MAME 0.216

With the end of November in sight, it’s time to check out MAME 0.216! We’ve addressed the reported issues with last month’s bgfx update, and made a whole lot of little improvements to MAME’s internal user interface. In particular, setting up controls should be easier, and several issues affecting macOS users with non-English number format settings have been fixed. Some of the issues caused bad settings to be written to INI files. If you still don’t see the filter list panel on the system selection menu, try removing the ui.ini file.
This month, we’re able to present two unreleased 1970s prototypes from Italian developer Model Racing: their internal code names are Cane and Orbite. With the assistance of former Model Racing employees, the source code was extracted from the original disks. These games are incomplete, but they provide a unique look into early CPU-based arcade development. Game & Watch titles continue to be emulated, with the addition of Mario The Juggler, and the panorama screen Mickey Mouse and Donkey Kong Circus games in this release.
This release brings GameKing emulation to MAME. The system-on-a-chip used in this low-cost, low-resolution hand-held console from the early 2000s has been identified and emulated. Games for the colour-screen GameKing III are also playable. Acorn BBC Micro emulation has been re-worked to support internal expansion boards, and a number of additional peripherals are now available. ZX Spectrum emulation has been enhanced with better open bus read behaviour and support for two Miles Gordon Technology peripherals.
Of course, these are just the highlights. You can get the source and Windows binary packages from the download page.

Netdata, the open-source real-time performance and health monitoring, released v1.18!

Hi all,
Release v1.18.0 contains 5 new collectors, 19 bug fixes, 28 improvements, and 20 documentation updates.
At a glance
The database engine is now the default method of storing metrics in Netdata. You immediately get more efficient and configurable long-term metrics storage without any work on your part. By saving recent metrics in RAM and "spilling" historical metrics to disk for long-term storage, the database engine is laying the foundation for many more improvements to distributed metrics.
We even have a tutorial on switching to the database engine and getting the most from it. Or, just read up on how performant the database engine really is.
Both our python.d and go.d plugins now have more intelligent auto-detection by periodically dump a list of active modules to disk. When Netdata starts, such as after a reboot, the plugins use this list of known services to re-establish metrics collection much more reliably. No more worrying if the service or application you need to monitor starts up minutes after Netdata.
Two of our new collectors will help those with Hadoop big data infrastructures. The HDFS and Zookeeper collection modules come with essential alarms requested by our community and Netdata's auto-detection capabilities to keep the required configuration to an absolute minimum. Read up on the process via our HDFS and Zookeeper tutorial.
Speaking of new collectors—we also added the ability to collect metrics from SLAB cache, Gearman, and vCenter Server Appliances.
Before v1.18, if you wanted to create alarms for each dimension in a single chart, you need to write separate entities for each dimension—not very efficient or user-friendly. New dimension templates fix that hassle. Now, a single entity can automatically generate alarms for any number of dimensions in a chart, even those you weren't aware of! Our tutorial on dimension templates has all the details.
v1.18 brings support for installing Netdata on offline or air-gapped systems. To help users comply with strict security policies, our installation scripts can now install Netdata using previously-downloaded tarball and checksums instead of downloading them at runtime. We have guides for installing offline via kickstart.sh or kickstart-static64.sh in our installation documentation . We're excited to bring real-time monitoring to once-inaccessible systems!

Part 2: Tools & Info for Sysadmins - Mega List of Tips, Tools, Books, Blogs & More

(continued from part 1)
Unlocker is a tool to help delete those irritating locked files that give you an error message like "cannot delete file" or "access is denied." It helps with killing processes, unloading DLLs, deleting index.dat files, as well as unlocking, deleting, renaming, and moving locked files—typically without requiring a reboot.
IIS Crypto's newest version adds advanced settings; registry backup; new, simpler templates; support for Windows Server 2019 and more. This tool lets you enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows and reorder SSL/TLS cipher suites from IIS, change advanced settings, implement best practices with a single click, create custom templates and test your website. Available in both command line and GUI versions.
RocketDock is an application launcher with a clean interface that lets you drag/drop shortcuts for easy access and minimize windows to the dock. Features running application indicators, multi-monitor support, alpha-blended PNG and ICO icons, auto-hide and popup on mouse over, positioning and layering options. Fully customizable, portable, and compatible with MobyDock, ObjectDock, RK Launcher and Y'z Dock skins. Works even on slower computers and is Unicode compliant. Suggested by lieutenantcigarette: "If you like the dock on MacOS but prefer to use Windows, RocketDock has you covered. A superb and highly customisable dock that you can add your favourites to for easy and elegant access."
Baby FTP Server offers only the basics, but with the power to serve as a foundation for a more-complex server. Features include multi-threading, a real-time server log, support for PASV and non-PASV mode, ability to set permissions for download/upload/rename/delete/create directory. Only allows anonymous connections. Our thanks to FatherPrax for suggesting this one.
Strace is a Linux diagnostic, debugging and instructional userspace tool with a traditional command-line interface. Uses the ptrace kernel feature to monitor and tamper with interactions between processes and the kernel, including system calls, signal deliveries and changes of process state.
exa is a small, fast replacement for ls with more features and better defaults. It uses colors to distinguish file types and metadata, and it recognizes symlinks, extended attributes and Git. All in one single binary. phils_lab describes it as "'ls' on steroids, written in Rust."
rsync is a faster file transfer program for Unix to bring remote files into sync. It sends just the differences in the files across the link, without requiring both sets of files to be present at one of the ends. Suggested by zorinlynx, who adds that "rsync is GODLY for moving data around efficiently. And if an rsync is interrupted, just run it again."
Matter Wiki is a simple WYSIWYG wiki that can help teams store and collaborate. Every article gets filed under a topic, transparently, so you can tell who made what changes to which document and when. Thanks to bciar-iwdc for the recommendation.
LockHunter is a file unlocking tool that enables you to delete files that are being blocked for unknown reasons. Can be useful for fighting malware and other programs that are causing trouble. Deletes files into the recycle bin so you can restore them if necessary. Chucky2401 finds it preferable to Unlocker, "since I am on Windows 7. There are no new updates since July 2017, but the last beta was in June of this year."
aria2 is a lightweight multi-source command-line download utility that supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. It can be manipulated via built-in JSON-RPC and XML-RPC interfaces. Recommended by jftuga, who appreciates it as a "cross-platform command line downloader (similar to wget or curl), but with the -x option can run a segmented download of a single file to increase throughput."
Free Services
Temp-Mail allows you to receive email at a temporary address that self-destructs after a certain period of time. Outwit all the forums, Wi-Fi owners, websites and blogs that insist you register to use them. Petti-The-Yeti says, "I don't give any company my direct email anymore. If I want to trial something but they ask for an email signup, I just grab a temporary email from here, sign up with it, and wait for the trial link or license info to come through. Then, you just download the file and close the website."
Duck DNS will point a DNS (sub domains of duckdns.org) to an IP of your choice. DDNS is a handy way for you to refer to a serverouter with an easily rememberable name for situations when the server's ip address will likely change. Suggested by xgnarf, who finds it "so much better for the free tier of noip—no 30-day nag to keep your host up."
Joe Sandbox detects and analyzes potential malicious files and URLs on Windows, Android, Mac OS, Linux and iOS for suspicious activities. It performs deep malware analysis and generates comprehensive and detailed reports. The Community Edition of Joe Sandbox Cloud allows you to run a maximum of 6 analyses per month, 3 per day on Windows, Linux and Android with limited analysis output. This one is from dangibbons94, who wanted to "share this cool service ... for malware analysis. I usually use Virus total for URL scanning, but this goes a lot more in depth. I just used basic analysis, which is free and enough for my needs."
Hybrid Analysis is a malware analysis service that detects and analyzes unknown threats for the community. This one was suggested by compupheonix, who adds that it "gets you super detailed reports... it's about the most fleshed out and detailed one I can find."
JustBeamIt is a file-transfer service that allows you to send files of any size via a peer-to-peer streaming model. Simply drag and drop your file and specify the recipient's email address. They will then receive a link that will trigger the download directly from your computer, so the file does not have to be uploaded to the service itself. The link is good for one download and expires after 10 minutes. Thanks to cooljacob204sfw for the recommendation!
ShieldsUP is a quick but powerful internet security checkup and information service. It was created by security researcher Steve Gibson to scan ports and let you know which ones have been opened through your firewalls or NAT routers.
Firefox Send is an encrypted file transfer service that allows you to share files up to 2.5GB from any browser or an Android app. Uses end-to-end encryption to keep data secure and offers security controls you can set. You can determine when your file link expires, the number of downloads, and whether to add a password. Your recipient receives a link to download the file, and they don’t need a Firefox account. This one comes from DePingus, who appreciates the focus on privacy. "They have E2E, expiring links, and a clear privacy policy."
Free DNS is a service where programmers share domain names with one another at no cost. Offers free hosting as well as dynamic DNS, static DNS, subdomain and domain hosting. They can host your domain's DNS as well as allowing you to register hostnames from domains they're hosting already. If you don't have a domain, you can sign up for a free account and create up to 5 subdomains off the domains others have contributed and point these hosts anywhere on the Internet. Thanks to 0x000000000000004C (yes, that's a username) for the suggestion!
ANY.RUN is an interactive malware analysis service for dynamic and static research of the majority of threats in any environment. It can provide a convenient in-depth analysis of new, unidentified malicious objects and help with the investigation of incidents. ImAshtonTurner appreciates it as "a great sandbox tool for viewing malware, etc."
Plik is a scalable, temporary file upload system similar to wetransfer that is written in golang. Thanks go to I_eat_Narwhals for this one!
Free My IP offers free, dynamic DNS. This service comes with no login, no ads, no newsletters, no links to click and no hassle. Kindly suggested by Jack of All Trades.
Mailinator provides free, temporary email inboxes on a receive-only, attachment-free system that requires no sign-up. All @mailinator.com addresses are public, readable and discoverable by anyone at any time—but are automatically deleted after a few hours. Can be a nice option for times when you to give out an address that won't be accessible longterm. Recommended by nachomountain, who's been using it "for years."
Magic Wormhole is a service for sending files directly with no intermediate upload, no web interface and no login. When both parties are online you with the minimal software installed, the wormhole is invoked via command line identifying the file you want to send. The server then provides a speakable, one-time-use password that you give the recipient. When they enter that password in their wormhole console, key exchange occurs and the download begins directly between your computers. rjohnson99 explains, "Magic Wormhole is sort of like JustBeamIt but is open-source and is built on Python. I use it a lot on Linux servers."
EveryCloud's Free Phish is our own, new Phishing Simulator. Once you've filled in the form and logged in, you can choose from lots of email templates (many of which we've coped from what we see in our Email Security business) and landing pages. Run a one-off free phish, then see who clicked or submitted data so you can understand where your organization is vulnerable and act accordingly.
Hardening Guides
CIS Hardening Guides contain the system security benchmarks developed by a global community of cybersecurity experts. Over 140 configuration guidelines are provided to help safeguard systems against threats. Recommended by cyanghost109 "to get a start on looking at hardening your own systems."

The Broadcast Storm is a podcast for Cisco networking professionals. BluePieceOfPaper suggests it "for people studying for their CCNA/NP. Kevin Wallace is a CCIE Collaboration so he knows his *ishk. Good format for learning too. Most podcasts are about 8-15 mins long and its 'usually' an exam topic. It will be something like "HSPR" but instead of just explaining it super boring like Ben Stein reading a powerpoint, he usually goes into a story about how (insert time in his career) HSPR would have been super useful..."

Tips
Here are a couple handy Windows shortcuts:
Here's a shortcut for a 4-pane explorer in Windows without installing 3rd-party software:
(Keep the win key down for the arrows, and no pauses.) Appreciation goes to ZAFJB for this one.
Our recent tip for a shortcut to get a 4-pane explorer in Windows, triggered this suggestion from SevaraB: "You can do that for an even larger grid of Windows by right-clicking the clock in the taskbar, and clicking 'Show windows side by side' to arrange them neatly. Did this for 4 rows of 6 windows when I had to have a quick 'n' dirty "video wall" of windows monitoring servers at our branches." ZAFJB adds that it actually works when you right-click "anywhere on the taskbar, except application icons or start button."
This tip comes courtesy of shipsass: "When I need to use Windows Explorer but I don't want to take my hands off the keyboard, I press Windows-E to launch Explorer and then Ctrl-L to jump to the address line and type my path. The Ctrl-L trick also works with any web browser, and it's an efficient way of talking less-technical people through instructions when 'browse to [location]' stumps them."
Clear browser history/cookies by pressing CTRL-SHIFT-DELETE on most major browsers. Thanks go to synapticpanda, who adds that this "saves me so much time when troubleshooting web apps where I am playing with the cache and such."
To rename a file with F2, while still editing the name of that file: Hit TAB to tab into the renaming of the next file. Thanks to abeeftaco for this one!
Alt-D is a reliable alternative to Ctrl-L for jumping to the address line in a browser. Thanks for this one go to fencepost_ajm, who explains: "Ctrl-L comes from the browser side as a shortcut for Location, Alt-D from the Windows Explorer side for Directory."
Browser shortcut: When typing a URL that ends with dot com, Ctrl + Enter will place the ".com" and take you to the page. Thanks to wpierre for this one!
This tip comes from anynonus, as something that daily that saves a few clicks: "Running a program with ctrl + shift + enter from start menu will start it as administrator (alt + y will select YES to run as admin) ... my user account is local admin [so] I don't feel like that is unsafe"
Building on our PowerShell resources, we received the following suggestion from halbaradkenafin: aka.ms/pskoans is "a way to learn PowerShell using PowerShell (and Pester). It's really cool and a bunch of folks have high praise for it (including a few teams within MSFT)."
Keyboard shortcut: If you already have an application open, hold ctrl + shift and middle click on the application in your task bar to open another instance as admin. Thanks go to Polymira for this one.
Remote Server Tip: "Critical advice. When testing out network configuration changes, prior to restarting the networking service or rebooting, always create a cron job that will restore your original network configuration and then reboot/restart networking on the machine after 5 minutes. If your config worked, you have enough time to remove it. If it didn't, it will fix itself. This is a beautifully simple solution that I learned from my old mentor at my very first job. I've held on to it for a long time." Thanks go to FrigidNox for the tip!

GullibleDetective tells us it offers "free PDF files from a WIIIIIIDE variety of topics, not even just IT. Only caveat: as its a vendor-supported publishing company, you will have to give them a bit of information such as name, email address and possibly a company name. You undoubtedly have the ability to create fake information on this, mind you. The articles range from Excel templates, learning python, powershell, nosql etc. to converged architecture."
SS64 is a web-based reference guide for syntax and examples of the most-common database and OS computing commands. Recommended by Petti-The-Yeti, who adds, "I use this site all the time to look up commands and find examples while I'm building CMD and PS1 scripts."
Phishing and Malware Reporting. This website helps you put a stop to scams by getting fraudulent pages blocked. Easily report phishing webpages so they can be added to blacklists in as little as 15 minutes of your report. "Player024 tells us, "I highly recommend anyone in the industry to bookmark this page...With an average of about 10 minutes of work, I'm usually able to take down the phishing pages we receive thanks to the links posted on that website."
A Slack Channel
Windows Admin Slack is a great drive-by resource for the Windows sysadmin. This team has 33 public channels in total that cover different areas of helpful content on Windows administration.
Blogs

An Infosec Slideshow
This security training slideshow was created for use during a quarterly infosec class. The content is offered generously by shalafi71, who adds, "Take this as a skeleton and flesh it out on your own. Take an hour or two and research the things I talk about. Tailor this to your own environment and users. Make it relevant to your people. Include corporate stories, include your audience, exclude yourself. This ain't about how smart you are at infosec, and I can't stress this enough, talk about how people can defend themselves. Give them things to look for and action they can take. No one gives a shit about your firewall rules."
Tech Tutorials
Tutorialspoint Library. This large collection of tech tutorials is a great resource for online learning. You'll find nearly 150 high-quality tutorials covering a wide array of languages and topics—from fundamentals to cutting-edge technologies. For example, this Powershell tutorial is designed for those with practical experience handling Windows-based Servers who want to learn how to install and use Windows Server 2012.
The Python Tutorial is a nice introduction to many of Python’s best features, enabling you to read and write Python modules and programs. It offers an understanding of the language's style and prepares you to learn more about the various Python library modules described in 'The Python Standard Library.' Kindly suggested by sharjeelsayed.
SysAdmin Humor
Day in the Life of a SysAdmin Episode 5: Lunch Break is an amusing look at a SysAdmin's attempt to take a brief lunch break. We imagine many of you can relate!
