Shit in -> shit out 📤

The reveal came as SAG-AFTRA actors confirmed they were going on strike.

cross-posted from: https://lemmy.ca/post/1418762

I've made a number of improvements since the last time I was posting about my extension. The update is now available on both Firefox and Chrome web stores.

For questions / support: [email protected]

TLDR: See the respective download pages on Firefox & Chrome. The screenshots and features list are mostly self-explanatory.

Note on versions:

• Firefox has a more recent 1.2.1 version, because my build script missed some files while uploading v1.2.0. It doesn't look like Chrome had this issue.
• I'm uploading v1.2.2 to both stores today, which will bring the two missing features to Chrome as well. After 1.2.2, all browsers should have the same features. See below for details.

So how is this different from other similar extensions?

You may have noticed the extension's name changed to be more generic (and include Kbin 🥳). I'm trying to make this a more well-rounded extension, and that means I've incorporated some features from the other extensions, in my own way.

Lemmy Links, Kbin Links, and the other forks:

This is a great extension that replaces links on your page with versions that go to your home instance. However, in order for this to work, it needs to recursively check every element on your page whenever DOM content (the stuff the browser is reading) changes. This is somewhat resource intensive, and while testing I ran into lag and freezing issues. As such, I decided to not include this functionality in the same way.

Instead, I've added a right click context menu that does the same thing. This way the user can pick which links they want the extension to convert, and it's a lot more efficient resource wise. While it's an extra click, I felt this was a reasonable compromise. However, I'm open to feedback!

NOTE: The context menu is available on Firefox, and it will be available in Chrome in about a week, depending on when they approve my update.

Lemmy Home Instance Helper

This is another extension which checks if you are logged in to an instance, and it creates a button to the search page if you are not. As my extension creates a button on any foreign instance, the search page is only helpful when a community hasn't been loaded into your home instance yet (ex. because you're the first one to try accessing it).

To deal with this, my extension modifies the "Community not found" pages with more instructions, as well as buttons to trigger the fetch process or to open the community elsewhere. See this screenshot for an example. Again, open to feedback!

As always, I'd love to collaborate with other people while building this. I'm still cleaning up my code, but feel free to look at the GitHub. If this extension gets popular, I will definitely need help for translations and for things like getting the extension on Safari (I don't have a recent Apple device to sign the extension with).

Note on permissions:

• The current versions request "Access to all sites". This is because the extension needs access to any page that contains "/c/", "/m/", or "/post/" in order to create the sidebar buttons. While the extension only looks for those pages, it will show up as "Access to all sites" when installing. Once I have a proper welcome message and settings page, I plan on making this permission optional so you can just use the popup menu if you would like.

Summary of Recent Changes:

• Added support for Kbin
• Fixed issue where button wouldn't load when navigating to a community within Lemmy (available on Firefox, should be on Chrome in a week).
• (NEW) Right-click context menu on Lemmy/Kbin community links to let you open them directly. You can test them out here: https://lemmy.ca/post/1282303 (available on Firefox, should be on Chrome in a week)
• (NEW) Information and buttons added to "Community Not Found" error pages to let you fetch the community or open it elsewhere.
• Updates to sidebar button to state the current selected instance and provide more detailed instructions as a dropdownList
• Refactored the code to remove more unnecessary permissions.
• Another pile of bugfixes, UI improvements, and better wording for instructions.

Future Plans:

• This is complete and will be in v1.2.2. ~~Bringing over the new changes to Google Chrome. Since chrome requires Manifest 3, I still need to iron out some issues with the service workers. The missing features are all related to the background processes that are running on the Firefox version~~
• Pushing to other browsers: Microsoft Edge & Opera are still reviewing v1.2.0. Unfortunately, I don't have any immediate plans for Safari, as I don't have a device that can sign the extension. I am looking into getting help for that.
• Setting up a proper Welcome page, Settings page, and Options menu to allow users to turn off features that they don't like. This will also let me make "access to all sites" optional.
• Finishing the translations' setup so that people can contribute other languages to the extension.
• Adding an option to save your own instances to the popup, for those that have multiple home instances.

OpenOrca-Preview1-13B Has Been Released!

• https://huggingface.co/Open-Orca/OpenOrca-Preview1-13B

The Open-Orca team has released OpenOrca-Preview1-13B, a preliminary model that leverages just 6% of their dataset, replicating the Orca paper from Microsoft Research. The model, fine-tuned on a curated set of 200k GPT-4 entries from the OpenOrca dataset, demonstrates significant improvements in reasoning capabilities, with a total training cost under $200. This achievement hints at the exciting potential of fine-tuning on the full dataset in future releases.

OpenOrca-Preview1-13B has shown impressive performance on challenging reasoning tasks from BigBench-Hard and AGIEval, as outlined in the Orca paper.

Even with a small fraction of the dataset, it achieved approximately 60% of the improvement seen in the Orca paper, offering encouraging insights into the scalability of the model. Furthermore, the Open-Orca team has made their Nomic Atlas Dataset Map available for visualizing their dataset, adding another layer of transparency and accessibility to their work.

I for one, absolutely love Nomic Atlas. The data visualization is incredible.

Nomic Atlas

Atlas enables you to: Store, update and organize multi-million point datasets of unstructured text, images and embeddings. Visually interact with embeddings of your data from a web browser. Operate over unstructured data and embeddings with topic modeling, semantic duplicate clustering and semantic search.

You should check out the Atlas for Open Orca. Data is beautiful!

Here are a few other notable metrics and benchmarks:

BigBench-Hard Performance

AGIEval Performance

Looks like they trained this with Axolotl. Love to see it.

Training

Built with Axolotl

We trained with 8x A100-80G GPUs for 15 hours. Commodity cost was < $200.

We trained for 4 epochs and selected a snapshot at 3 epochs for peak performance.

What an exciting model! Can't wait to see the next wave of releases. It's worth mentioning orca_mini, which is worth checking out if you like this new open-source family of LLMs.

The/CUT (TLDR)

The Open-Orca team has made a groundbreaking open-source breakthrough, creating a cost-effective AI model, OpenOrca-Preview1-13B, that thinks and reasons better using only a tiny portion of their data. This work not only highlights the power of community-driven innovation, but also makes advanced AI accessible and affordable for everyone.

We're happy to announce the release of BusKill v0.7.0!

Most importantly, this release allows you to arm the BusKill GUI app such that it shuts-down your computer when the BusKill cable's connection to the computer is severed.

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Watch the BusKill Explainer Video for more info youtube.com/v/qPwyoD_cQR4

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

Upgrading

You can upgrade your BusKill app to the latest version either by

1. Clicking "Update" in the app or
2. Downloading it from GitHub

Changes

This update includes many bug fixes and new features, including:

1. Adds support for 'soft-shutdown' trigger to GUI
2. Adds a new buskill.ini config file
3. Adds a new "Settings" screen in GUI
4. Merges kivy & buskill config files into one standardized location
5. Fixes in-app updates on MacOS
6. Fixes lockscreen trigger on Linux Mint Cinnamon
7. Fixes background blue/red disarm/arm color to propagate to all screens
8. Fixes --run-trigger to be executed inside usb_handler child process and communicate to root_child through the parent process

You can find our changelog here:

• https://docs.buskill.in/buskill-app/en/stable/changelog.html

Documentation Improvements

We've also made many improvements to our documentation

1. Updated the Software User Guide to include how to arm the BusKill app with the soft-shutdown trigger in the GUI
2. Added a manpage
3. Better documentation on how to build your own USB-C BusKill Cable
4. Better documentation on how to test the buskill app
5. Fixes in Release Workflow
6. Added some additional related projects to our documentation

Soft-Shutdown Trigger

This release now allows you to choose between either [a] locking your screen or [b] shutting down your computer when you arm the BusKill app from the GUI. By default, the BusKill app will trigger the lockscreen. To choose the 'soft-shutdown' trigger, open the navigation drawer, go to the Settings Screen, click Trigger, and change the selected trigger from lock-screen to soft-shutdown. For more information, see our Software GUI User Guide.

• https://docs.buskill.in/buskill-app/en/v0.7.0/software_usr/cli.html

BusKill Now in Debian!

We're also happy to announce that, with the release of Debian 12, it's now possible to install BusKill in Debian with Apt!

sudo apt-get install buskill

Testers Needed!

We do our best to test the BusKill app on Linux, Windows, and MacOS. But unfortunately it's possible that our app doesn't fully function on all versions, distributions, and flavours of these three platforms.

We could really use your help testing the BusKill app, especially if you have access to a system that's not (yet) listed in our Supported Platforms.

And in this release, we specifically would like you to help us test the new soft shutdown feature. Please let us know if it does or does not work for you.

Please contact us if you'd like to help test the BusKill app :)

Textual words from them:

It’s our first step towards a more modern, more beautiful, and more customizable Thunderbird experience. We think you’re going to love it, and we are endlessly grateful for all of your support throughout the years 💙
