For the last few years my primary source of Industry 4.0 information comes from the publication of a single person.

Industry 4.0 is big, Big, BIG money - if you do not have a few million per year to invest nobody is interested talking to you. So following one or maximum two reliable sources is plenty enough. When millions of dollars involved everyone has something to say, of course, and you can spend your entire life reading about things and concepts which are entirely irrelevant to you.

This I highly recommend:

Now, as I browse the connection suggestions start.hubzilla 404s immediately - what a time-saver! It was frustrating to visit all those abandoned projects.

A few days ago I installed I2P, and spent a weekend on the same thing - browsing all the abandoned pages and links. Finding and maintaining active connections is becoming some sort of currency, the attention you pay and you get is becoming increasingly valuable. Its too easy to waste your resources in overly or scarcely populated communities.

Installing JupyterLab on a remote VPS

Since YunoHost currently fails to run JupyterLab I need to install it manually.. I just posted this on Gab

I would like to install JupyterLab on a remote non-production Debian 10 VPS, staring it automatically, and running any instances or "virtual environments" as non-root. This is what I did so far:

# apt install python3 python3-venv
# apt install virtualenv python3-virtualenv
# apt install pipenv
# pipenv install jupyterlab

At this point I ran these commands I believe show what I wanted to see...
root@remotevps:~# pipenv --venv
/root/.local/share/virtualenvs/root-BuDEOXnJ
root@remotevps:~# pipenv --py
/root/.local/share/virtualenvs/root-BuDEOXnJ/bin/python
root@remotevps:~# pipenv --where
/root

I hope this left the root environment as it should be, nothing is installed or pointing to /root

Part II - Creating a non-priviledged user (but adding it to the sudoers)
adduser remote_user
usermod -aG sudo remote_user
usermod --shell /bin/sh remote_user
su -l remote_user

So my current status is:

$ pipenv --venv
No virtualenv has been created for this project yet!
$ pipenv --py
No project found!
$ pipenv --where
No Pipfile present at project home. Consider running `pipenv install` first to automatically generate a Pipfile for you.

I did not create any virtualenv as root, and nothing is created (yet) for this user. Anyone could explain what is happening so far, and what should I do next?

Thanks!

Benjamin Shelton (I think he is an Arc Linux dev) solved this:

You don't need pipenv to install virtualenvs, not with Python 3, and pipenv is probably going to complicate things. Use the following as the user you intend to run Jupyter as:

$ python3 -m venv .python
$ source .python/bin/activate
$ pip install --upgrade pip # sometimes necessary to upgrade pip first; skip this if it doesn't give you any warnings.
$ pip install jupyterlab

Not working for me. It installs fine, but then it fails to start or "spawn". I get the error:

I am still looking for a Linux VPS provider in Hungary or in Poland, with specific requirements. The physical boxes must be located in those countries, it must have an English language dashboard, should support IPv6, and support update of rDNS for both IPv. I already have Linode and OVH accounts, I need a third one. Any suggestions are appreciated!

hosting.linux.pl is no good, they do not have a control panel in English and I cannot read Polish. I can read Hungarian, but when the DNS administration is shared English is the only language that is going to work for everyone.

Ok, I finally got this this one:
@Anmol Sharma
It failed installation, I used the YunoPaste to send the log to #^https://paste.yunohost.org/raw/vozikatefe

Let me know if you want me to try again, I am keeping that YunoHost instance and a subdomain just for this app.
It seems the installation script rolled back the changes - but I have a snapshot of the VPS and I can start brand new.

The YunoHost VPS passes all diagnostics, and the subdomain is fully RFC-compliant with Let's Encrypt cert.

I still need to figure everything out in Hubzilla, but I have so many projects it has to wait. I am going to try and keep my scheduled events private in the future for sure. I am glad I did not leak my hemorrhoids surgery appointment coming up on the 30th of March at 90:30 AM, that would be really embarrassing!
