A while ago, I had requested help with using LLMs to manage all my teaching notes. I have since installed Ollama and been playing with it to get a feel for the setup.

I was also suggested the use of RAG (Retrieval Augmented Generation ) and CA (cognitive architecture). However, I am unclear on good self hosted options for these two tasks. Could you please suggest a few?

For example, I tried ragflow.io and installed it on my system, but it seems I need to setup an account with a username and password to use it. It remains unclear if I can use the system offline like the base ollama model, and that information won't be sent from my computer system.

I am an EU citizen and I was informed that my EURAXESS account was breached. They informed me that while the password wasn't stolen, all of my personal data including addresses, IDs from the CV was stolen and made available on some website.

They say that they're working towards making the site secure, etc., but I know that my personal info is out there. They have even told me to watch out for scams and phishing attempts over the next few months to come.

I am a bit shaken. Please tell me what steps I can take to gain back some control over this situation?

I have received a lot of PDF documents that I wish to convert to text formats such as docx/doc/odt.

I know there are some online tools that will do it for you, but some content may be sensitive with people's names and addresses and I'm not sure I can trust these websites.

Are there software that will convert a PDF to odt?

Things I know and tried:

1. Asked a friend to open PDF in Microsoft Word: Their license expired last month, so it doesn't let you save the file!

2. Tried to do the same on my LibreWriter: It doesn't support that format.

3. Tried to open in LibreDraw: untenable as I want to type more things in the document.

P.S: I use Linux, but reckon solutions for platforms would be fine.

There are many corrupt people in the government, both elected politicians and unelected officials. Many are p#do***les, other launder money, some rig elections, while others surveil and harass innocent people.

To protect our Parliament, and Constitution, all these politicians and their families should come under public scrutiny. All their financial records, their communications, their online search histories, should be in the public domain.

In other words, we need parity of privacy between the State and its People.

This sounds hair-brained and extreme, but the public is already under intensive surveillance. I think experience needs to be felt by the officials as well so they finally begin to value the fundamental right to privacy.

I rarely use my smartphone and find it a bit annoying to have to use it for 2FA through apps. I wish to get physical passkeys that will allow me to login to my laptop.

I have heard of YubiKey although I haven't given it any serious consideration since it is closed source. (My super-tin-foiled friend who introduced me to this world of privacy taught me to never trust a closed-source solution... _long _ story).

Are there any FLOSS versions of Yubikey? Can they be used to log into a Linux machine? Or for banking?

I understand that people enter the world of self hosting for various reasons. I am trying to dip my toes in this ocean to try and get away from privacy-offending centralised services such as Google, Cloudflare, AWS, etc.

As I spend more time here, I realise that it is practically impossible; especially for a newcomer, to setup any any usable self hosted web service without relying on these corporate behemoths.

I wanted to have my own little static website and alongside that run Immich, but I find that without Cloudflare, Google, and AWS, I run the risk of getting DDOSed or hacked. Also, since the physical server will be hosted at my home (to avoid AWS), there is a serious risk of infecting all devices at home as well (currently reading about VLANS to avoid this).

Am I correct in thinking that avoiding these corporations is impossible (and make peace with this situation), or are there ways to circumvent these giants and still have a good experience self hosting and using web services, even as a newcomer (all without draining my pockets too much)?

Edit: I was working on a lot of misconceptions and still have a lot of learn. Thank you all for your answers.

I am working on a simple static website that gives visitors basic information about myself and the work I do. I want this as a way use to introduce myself to potential clients, collaborators, etc., rather than rely solely on LinkedIn as my visiting card.

This may seem sound rather oxymoronic given that I am literally going to be placing (some relevant) details about myself and my work on the internet, but I want to limit the websites' access from bots, web scraping and content collection for LLMs.

Is this a realistic expectation?

Also, any suggestions on privacy respecting, yet inexpensive domains that I can purchase in Europe would be of super great help.

I am a teacher and I have a LOT of different literature material that I wish to study, and play around with.

I wish to have a self-hosted and reasonably smart LLM into which I can feed all the textual material I have generated over the years. I would be interested to see if this model can answer some of my subjective course questions that I have set over my exams, or write small paragraphs about the topic I teach.

In terms of hardware, I have an old Lenovo laptop with an NVIDIA graphics card.

P.S: I am not technically very experienced. I run Linux and can do very basic stuff. Never self hosted anything other than LibreTranslate and a pihole!
