Hmm, very interesting! This could definitely go further into the first scenario. Perhaps the summoner is now a "puppet" for the entity, and is trying to trick the more resilient player characters to succumb to the entity's control. Perhaps the first ritual weeded off the weaker candidates, and now the entity is preparing to give them the full course.

I'm curious what you're going to go with :D

The go-to monkey paw scenario could work, where they receive immortality, but have to serve the summoned entity forever as deformed (and perhaps always hurting) "things"? However, that is maybe a bit too predictable. What if they mess up the spell and instead mark themselves for sacrifice?

They slowly realise this due to a symbol appearing on them, which could slowly spread further on their body (maybe hurting too). You could make it more interesting by pitting them against one another by suggesting that only a few have to die for the sacrifice to be complete. If their characters are not that close to one another, it could lead to some interesting decisions on their part, haha.

The process could span a week or more, where their body gets engulfed more and more by the mark. They could use this time to review what went wrong in the summoning process, and how to potentially reverse it. I'll leave those details to you, if you're interested in pursuing this idea :D

I'm really sorry to hear that. I hope you have enough support to deal with it!

Regarding bioinformatics, it doesn't have to be a human-centered job. You can get into the data science aspect of it, and make good money off of helping research diseases, for example. This could also be a remote job, and you'd probably have an easier time getting into it. For data science, you can get quite far with Python, which is easier to pick up when compared with other languages.

You can also explore your options further by just asking ChatGPT, and seeing what the potential job requirements would be. It's decent if you want to brainstorm some stuff, but do look up the information yourself on search engines. Write there your experience, what you'd want, and what to expect if you were to jump in that field. Perhaps this could help you decide better.

I wish you the best of luck!

If you already have medical knowledge, why not look into bioinformatics? Cyber security would be a pretty big jump if you're not into tweaking computers as a hobby. For example, have you ever set up Linux on your own?

Certifications will give you a starting point, but it will take years for all the information to settle properly in your mind.

Piracy. I'd buy albums if I had money, though. I'll slowly phase into getting them once I get some more cash.

I can find most stuff I listen to, and I rarely grow my music library. I mostly listen to 20-30 albums, with some more mainstream music peppered in.

My music library currently sits at 90 gigabytes (mostly flacs), so quite small compared to others I've seen around here. Still, I have plenty of variation to keep me entertained :D

If you have Tidal, aren't there some apps to rip the lossless audio from there? You could get most of the stuff that you need, and then cancel the subscription. If you feel bad, maybe order some merch from the band, haha.

Click for longer opinionIf I remember correctly, even though Fuchsia is used in production, it is mainly targetting mobile or IoT devices. Nevertheless, the underlying micro-kernel, Zircon, is written in C/C++, which differs from Redox. Now, I'm not saying that Redox solves everything by writing the kernel in Rust. It will require plenty unsafe blocks to achieve what it needs, but it makes you aware beforehand that you should be careful about how you implement that bit of code. Having this clear marking could also make the kernel code review process more likely to catch issues.

Disregarding this, if I am not mistaken, Redox aims to be a drop-in replacement for Linux one day, both for desktop and server, while Fuchsia only wishes to be integrated in/replace Android. Linux is perfectly fine for most use cases, I am not suggesting otherwise! However, given how many issues resulted from overflow/memory corruption issues that could have been potentially easier to identify if Rust (or any other memory safe language) was used, you'd think that there is incentive to rely on it for kernel development. Linus himself made this decision as well when allowing Rust to be used in the Linux kernel development (albeit perhaps a bit too early).

The Linux kernel is not flawed, and Redox is probably years away from being even near it. However, having memory-safety from the get-go as a requirement for developing the kernel could lead to fewer exploits, compared to what we have today with Linux. Just as you've said, most users are not aware of it/they don't care, but the big players will care about keeping information safe on their servers. Just to conclude, Redox OS is not just Linux rewritten in Rust, and could potentially have many other benefits that are particularly juicy for data centers. Too bad it's not production ready yet :D

[–] andrew0@lemmy.dbzer0.com 3 points 1 month ago

That's unfortunate :( I think you can still run it in QEMU, if you're interested.

[–] andrew0@lemmy.dbzer0.com 11 points 1 month ago (2 children)

I see your point. However, integrating Rust properly in the Linux kernel is an uphill battle. Redox OS is not at all close to being stable, but it showcases that you can build a Rust kernel from scratch, and integrate it into an OS that meets some of the requirements of a modern one. Of course, considering it a toy project and glancing over its potential doesn't help with adoption. They even mention in their description that currently they can only support a community manager and a student developer with the current donations. When you compare that to the amount of money and developers involved in the Linux kernel, it's insignificant.

I was not suggesting that the Rust For Linux devs jump ship, but it could be beneficial for the investors behind the project to look at alternatives. Heck, the Linux kernel started as a toy project itself. I believe that a team focused solely on such a Rust-only kernel could spearhead needed changes to reach something stable, as opposed to investing time and money into fighting established C developers to integrate a memory-safe language in the kernel fully.

I recently discovered that Redox OS got a new release earlier this month. I'm quite surprised how far they managed to get, given that only a handful of people are working on this project (compared to the Linux kernel).

Now, I'm curious what it would take to get bigger players to focus on this project. Given the recent Linux + Rust drama, it would surprise me if the backers of Rust for Linux would not give this project some attention.

If I am not mistaken, the difference was that the Internet Archive was distributing books with a DRM that would make the PDF unusable after a certain time. You could relate it to how a physical library offers books for a limited time, for free. Now, of course, one could bypass the DRM or copy the contents differently, but so can another person photocopy a book they borrowed physically. Meanwhile, other physical libraries are allowed to distribute e-books, but I'm not sure if that's made possible due to licensing fees.

I'm not saying that they approached this well, especially given the copyright laws in the US, but it was indeed a good thing for the normal person at the time. Too bad that the judicial system in the US is biased towards leeching companies. I really can't wait to see the AI vs publishers fight, though. Let's see who has deeper pockets and better plants in the courts :D

~~I think it might be Magic Research 2?~~ Nevermind, I couldn't find that review on the Steam page, so it must be another game.

Organic Maps. Make sure you download the areas beforehand. The resolution for walking paths is much nicer, and you can clearly see the routes of temples and other points of interest.

It also shows data about drinking faucets, toilets, and other things provided by users.

You're right. I read past the "I want to learn ML" and went straight to "do something useful with the data".

If the goal is to understand how modern LLMs work, it's also good to read up on RNNs and LSTMs. For this, 3Blue1Brown does an amazing job, and even posted an in-depth video about transformers. I'd watch that next, followed by implementing a simple transformer in PyTorch (perhaps using the existing blocks).

You could argue that it's important to design everything from scratch first, but it's easier to first go high level, see how the network behaves, and then attempt to implement it yourself based on the paper. It is up to OP how comfortable he is with the topic though 😁

 

Hello everyone! I've been playing around with Wayland for a bit and was hoping to start learning some more about it. For example, I would be interested in making a lock screen, similar to Swaylock, as a toy project.

What GUI toolkit would you use to develop apps on Wayland? I've added a little poll below with some of the popular choices I've seen thrown around. Feel free to add your own suggestions and maybe leave a comment as to why you'd use that!

Hi! I am trying to automate my install process by creating a json file that can be used by archinstall (example). One of the example shows how you can run custom commands to get paru (yay, but written in Rust):

"custom-commands": [
        "cd /home/devel; git clone https://aur.archlinux.org/paru.git",
        "chown -R devel:devel /home/devel/paru",
    ]

However, their example doesn't provide any further information about installing packages with paru. I would like to install some stuff just for my user.

My idea was the following:

  • using archinstall, install everything according to the config
  • disregard the "custom-commands" option in the config and create a separate custom script
  • get all the users from the system and allow user to choose which one to chroot as
  • run all commands as the chosen user ( e.g., install Rust with curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh )

I need to install a few packages that are not in the official repository, as well as moving my dotfiles in /home/user/.config and making sure everything is accessible by that user. If there are any better approaches to this, I would be glad to hear them!

An example of the script I am planning to use after running archinstall:

spoiler

#!/bin/bash

# Find all users on the system
for user in $(ls /home); do
    if [ "$user" != "lost+found" ]; then
        users+=($user)
    fi
done

# If there is more than one user, ask which user to install for
if [ ${#users[@]} -gt 1 ]; then
    echo "Multiple users found on system. Please select a user to install for:"
    select user in "${users[@]}"; do
        if [[ " ${users[@]} " =~ " ${user} " ]]; then
            break
        else
            echo "Invalid selection"
        fi
    done
else
    user=${users[0]}
fi

echo "Installing for user $user"

# chroot as the user
arch-chroot -u $user /mnt/archinstall # This only opens bash, but I am working on it :D 
cd /home/$user

# Install paru
git clone https://aur.archlinux.org/paru.git
cd paru
makepkg -si

# Install stuff with paru
paru -S tlrc --noconfirm

 

Server performance is not very good with so many mods, and I have been looking into ways to fix this. One of the latest comments on the ATM8 page on CurseForge is from XZot1K, and says the following:

After lots of testing I resolved most of my issues by installing the following mods to the server (Ensure to install the correct versions, as of writing this the version is latest of each for 1.19.2):

https://www.curseforge.com/minecraft/mc-mods/too-fast

https://www.curseforge.com/minecraft/mc-mods/smooth-chunk-save

https://www.curseforge.com/minecraft/mc-mods/chunk-sending-forge-fabric

https://www.curseforge.com/minecraft/mc-mods/packet-size-doubler

These mods will resolve larger packet disconnect issues, chunk lag, and irregular movement rubber banding.

In addition to these, for further improvement, set the tick rate to -1 in the server.properties file.

Paste the following into the bottom of your "user_jvm_args.txt" (change the 6GB and 256m to your liking


Xms must be less than Xmx):

-Xmx6G -Xms256m -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=32M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true

Please note that while these additional mods do work on the client the major improvement comes from the server-side.

I've already used those jvm arguments, but I didn't look for performance mods before. Now, after fiddling a bit around with them, the server feels much snappier (and I don't have to install anything client side)! I'm hosting on Azure, with a Standard D2s v3 (2 vcpus, 8 GiB memory) VM, and when I would do a /home from a far away place it would take a few seconds to load. Now, it's almost instantaneous! Thanks XZot1K! :)

The server also used to crash whenever multiple people entered the Nether, but I haven't been able to test this yet with the new configuration.

If you have any tips to improve performance, please share them here :)

Jump from Arch to NixOS? (lemmy.dbzer0.com)
submitted 1 year ago* (last edited 1 year ago) by andrew0@lemmy.dbzer0.com to c/linux@lemmy.ml
 

As the title implies, should I do it? I love Arch so far, and I can fix most issues that pop out. However, I sometimes wish to start fresh without too much hassle, but I get a feeling NixOS isn't as mature as Arch.

Have any of you used both, and if so, what do you miss from Arch? What are you grateful for in NixOS?

Hi everyone! I'll soon take the DP-100 exam for Microsoft Azure, and I was interested in finding more leaked exam questions. At the moment, I was using examtopics for this, but it sucks because it basically cuts you off halfway through.

I heard there are some private trackers that specialize in exam questions, such as LearnFlakes, but I do not have anyone that can invite me to them. Therefore, I was wondering if there is another way to find the information I need for this exam.

Do you know any other sources that are fully free?
