Nice work this definitely feels like a market gap, for those who’ve been deep enough to experience it.


Thank you!


Great news for all involved. It also would seem to validate Apple’s unified architecture for inference, and imply AMD is getting close…


You mean AMD's unified architecture. They were a founder of the HSA Foundation that drove innovation in this space complete with Linux kernel investments and unified compute SDKs, and they had the first shipping hardware support.


This is a strong take.

AMD's actual commitment to open innovation over the past ~20 years has been game changing in a lot of segments. It is the aspect of AMD that makes it so much more appealing than intel from a hacker/consumer perspective.


Will typically connect Microsoft 365 email to owned domain and pricing is relatively cheap and it works great.


Sharing for awareness in case of value for any HNers, this little app helped get subscriptions online for a hobby project and has now been open sourced (MIT). There are bigger established alternatives and as is explained in the readme, this one is designed to be encapsulated, ideomatic, and end-user privacy-preserving.


Right?!


Anyone know of a similar option for vi/m? (Not neovim etc).

Been searching and have found some but nothing stands out yet.


You could use Emacs in evil-mode.


Seconding this recommendation! I've never been a super advanced vim user, but Evil is the best and most complete vim emulator I've ever used, and I try them on every editor or IDE I ever run.


Seems some of these are for Vim too, but I haven’t tried them yet: https://github.com/jkitching/awesome-vim-llm-plugins Scanning the list quickly, dense-analysis/neural perhaps sticks out since it’s written by the author of ALE, which is a very high-quality plugin.

Another option that is perhaps more the Unix way, is to run an LLM client in a terminal split (there are lots of CLI clients), and then use vim-slime to send code and text to that split.

Personally I’m still using ChatGPT in the browser and mobile app. Would love to try something else, but the OpenAI API key seems to cost extra, and something like llama probably takes time to setup right.


I’ve been happy with vim-ai plugin: https://github.com/madox2/vim-ai


We need a tl;dr on this one!


At a very quick skim, seems she detected and decoded the RDS signal in the 57kHz subcarrier of an FM broadcast.

That Media Realm site is mine. Thanks for linking! RDS is one of those technologies that’s been around for decades and still amazes people. You can buy hardware encoders for about AU$500 these days, and I love introducing stations to it and getting their name and song data to show up on car radios.


This is the blog post[1] from the presenter explaining part of it, with this request in the messages lol:

- Sad to request, but can you take thisoffline. It is kind of our service you hacked :)

Thank you for that! I didn’t have the patience for the video, but I found her pen-and-paper decryption in that blog post absolutely lovely.


That “take this post down on the first appearance of any complaint from any party” tact sure changed in a hurry, huh


1.75x, I can't watch any video at any other speed at this point.


Ever tried with Louis Rossmanns or Network Chuck videos? I can't watch them at more than 0.75.

She was aware but the talk is a walk through how easy hacking is. Not giving up and being interested enough to find out more. Really recommend the talk and her blog.


This!

Unless something is theoretical impossible, the only thing stopping a determined hacker is the amount of time and coffee in reserves.


You managed to be incorrect twice in one sentence. Well done. Actually watch the video. It's quite interesting.


enjoy patronising dont you? not well done

These are great. Having tooling to get stuff out fast and as safely as possible to get to iterating openly.

Here’s a bash script I posted a while back on a different thread that does similar thing if of interest for anyone. It’s probably less nice than op’s for ex it only works with digitalocean (which is great!) - but it’s simple small and mostly readable. also assumes docker - but all via compose, with some samples like nginx w auto-ssl via le.

Imho there is hype and bubble yes but not at the core: at the core is AGI in 5 years and significant change. The bubble/hype is coming from where it seems to always come from - the non-core camp.


LLMs aren't in the direction of AGI. Are you talking about some other branch of AI?


Anyone know of open models useful (and good quality) for going the other way? I.e., Input is a 800x600 jpg and output is 4k version.


Magnific.ai (https://magnific.ai) is a paid tool that works well, but it is expensive.

However, this weekend someone released an open-source version which has a similar output. (https://replicate.com/philipp1337x/clarity-upscaler)

I'd recommend trying it. It takes a few tries to get the correct input parameters, and I've noticed anything approaching 4× scale tends to add unwanted hallucinations.

For example, I had a picture of a bear I made with Midjourney. At a scale of 2×, it looked great. At a scale of 4×, it adds bear faces into the fur. It also tends to turn human faces into completely different people if they start too small.

When it works, though, it really works. The detail it adds can be incredibly realistic.

Example bear images:

1. The original from Midjourney: https://i.imgur.com/HNlofCw.jpeg

2. Upscaled 2×: https://i.imgur.com/wvcG6j3.jpeg

3. Upscaled 4×: https://i.imgur.com/Et9Gfgj.jpeg

----------

The same person also released a lower-level version with more parameters to tinker with. (https://replicate.com/philipp1337x/multidiffusion-upscaler)


That magnific.ai thingy is taking a lot of liberty on the images, and denaturing it.

Their example with the cake is the most obvious. To me, the original image shows a delicious cake, and the modified one shows a cake that I would rather not eat...


Every single one of their before & after photos looks worse in the after.

The cartoons & illustrations lose all of their gradations in feeling & tone with every outline a harsh edge. The landscapes lose any sense of lushness and atmosphere, instead taking a high-clarity HDR look. Faces have blemishes inserted the original actor never had. Fruit is replaced with wax imitation.

As an artist, I would never run any of my art through anything like this.


Here's free and open source alternative that works pretty well

https://www.upscayl.org/


Both of these links to replicate 404 for me



Look for SuperResolution. These models will typically come as a GAN, Normalizing Flow (or Score, NODE), or more recently Diffusion (or SNODE) (or some combination!). The one you want will depend on your computational resources, how lossy you are willing to be, and your image domain (if you're unwilling to tune). Real time (>60fps) is typically going to be a GAN or flow.

Make sure to test the models before you deploy. Nothing will be lossless doing superresolution but flows can get you lossless in compression.



I haven't explored the current SOTA recently, but super-resolution has been pretty good for a lot of tasks for few years at least. Probably just start with hugging-face [0] and try a few out, especially diffusion-based models.

[0] https://huggingface.co/docs/diffusers/api/pipelines/stable_d...


Current SOTA open source is I believe SUPIR (Example - https://replicate.com/p/okgiybdbnlcpu23suvqq6lufze), but it needs a lot of VRAM, or you can run it through replicate, or here's the repo (https://github.com/Fanghua-Yu/SUPIR)


You’re looking for what’s called upscaling, like with Stable Diffusion: https://huggingface.co/stabilityai/stable-diffusion-x4-upsca...


There are a bunch of great upscaler models although they tend to hallucinate a bit, I personally use magic-image-refiner:

https://replicate.com/collections/super-resolution


This is called super resolution (SR). 2x SR is pretty safe and easy (so every pixel in becomes 2x2 out, in your example 800x600->1600x1200). Higher scalings are a lot harder and prone to hallucination, weird texturing, etc.


thank you! will enjoy reviewing each of these
