Fixing Ollama Installation on Manjaro + NVIDIA
Tags: ollama, manjaro, nvidia
Published: 2024-07-11 11:54:12

The current Ollama version in Arch is outdated (`0.1.44` vs `0.2.1` latest). The official install script doesn't support some Manjaro configurations, but don't worry—I've got the fix!

## The Problem 🤔
When I tried running the install script, I got hit with this:
```sh
curl -fsSL https://ollama.com/install.sh | sh
# sh: line 252: VERSION_ID: unbound variable
```

This cryptic error just means you're missing those NVIDIA drivers, and Ollama can't sort that out for you.

## Step-by-Step Fix 🏌️
**step 1**: find your linux kernel verion:
```sh
uname -r
# 6.9.5-1-MANJARO
pamac search "linux.*header"
# linux69-headers  6.9.5-1 [Installed]
```

**step 2** install everything you need
```sh
pamac install nvidia nvidia-utils cuda linux69-headers
```

**step 3** you might want to restart your Linux just to be on the safe side

**step 4**  Now, run the install script again:

```sh
curl -fsSL https://ollama.com/install.sh | sh
# ollama successfully installs on your Manjaro system!
```

🏆 Boom! Done!

## Troubleshooting  🕵️‍♂️
Here's how you can check the successful installation:

1) Run `nvidia-smi` and your video card should show up.
2) Make sure that your video card and its device ID are in the OLLAMA's logs

```sh
journalctl -u ollama | grep "id=.*NVIDIA"
# ollama[2174]: [...] id=GPU-3a31a7cb-e46b-458c-9a92-ea9708b0c7fa library=cuda compute=8.9 driver=12.4 name="NVIDIA GeForce RTX 4090 Laptop GPU" total="15.7 GiB" available="15.5 GiB"
```

## Quick Note for Wayland + GNOME Users
Even after I installed drivers, my Wayland still uses integrated video graphics.

BitPower's mechanism:
Published: 2024-07-11 11:59:54

BitPower Loop automates all transactions through smart contracts, eliminating human intervention and ensuring security and transparency. Users do not need to trust third parties, reducing the risks caused by trust issues. Borrowers can provide crypto assets as collateral to increase lending capacity and reduce interest rates. Interest rates are calculated dynamically based on supply and demand, and the process is transparent and fair. Users can also receive referral rewards by inviting new users and earn multi-level rewards based on the newly added circulation amount.

In addition, BitPower Lending is based on BSC (Binance Smart Chain), uses algorithms to determine interest rates, and establishes a transparent public ledger to record all transactions and historical interest rates to ensure fairness. BitPower provides services worldwide, simplifies the loan application process, improves efficiency and convenience, and becomes a leading decentralized financial platform.

A new project for Rust Developers??
Tags: programming, opensource, rust, beginners
Published: 2024-07-11 12:25:19

## Announcing Rustcrab: The Repository for Rust Developers That Isn't Crap

You might think I'm diving deep into Rust with what I've done so far, but that was just the beginning. Trust Francesco.

## It's Time for an Announcement

I've officially started a new project called:

**"Rustcrab, the repository for Rust Developers that isn't crap"**

This project aims to create a free, open-source resource dedicated to the Rust programming language.

I will only share meaningful information about the Rust community, resources, news, projects, dev tools, and as much as possible. The project is 100% open-source and free.

### What I've Done So Far:

- Bought the domain using NameCheap
- Created a Next.js project and deployed it to Vercel
- Linked the custom domain to Vercel
- Created a very minimal page that includes light and dark modes, real-time GitHub stars, and social profiles
- Integrated Substack email (it might be improved in the future, but for now it works)

Thanks to AI's support, all this was done in just a few hours. It's incredible how AI can speed up the process if you know what you're doing but want it done quickly.

This is how it looks right now. It's pretty basic, and not much on it, but I will keep working on it.

### What's Next:

- Add more sections
- Promote the project
- Send email updates
- Create some live events about this

Feel free to check the GitHub repository: [Rustcrab GitHub Repository](https://github.com/FrancescoXX/rustcrab)

### Why All of This?

Well, because this is basically what I have been doing every day for more than six months: checking @dailydotdev, organizing things, making private lists and notes, and so on. I think it's time for this project to be more open and accessible to everyone.

I will also create a separate channel on Discord for discussions.

If you are interested in this project, subscribe to the newsletter and star the repo (only two stars now).

I will update you in the next few days.

The project aims to make your life easier if you want to get involved with the Rust community, resources, and updates. Rust is not for everyone, but if you want to make a bet on the future of your tech career, this is a great opportunity to stop making excuses and get started.

### Disclaimer

For now, it's not even worth checking, but I've learned that the sooner you launch, the better. Feel free to add issues in the GitHub repository, and I will work on that. I can also do some work live.

Well, that was a long post.

If you reached the end, that already means a lot to me.

Thank you
