Show HN: Radiotron (alpha) a Fast Medical Segmentation and Visualization Tool

Grieverheart — Fri, 12 Dec 2025 15:28:24 +0000

Some years back I was working on a medical imaging project and was frustrated by the lack of available tools for segmentation that are simple to use and fast. Because of this frustration I started working on a medical image segmentation software with a focus on performance and simplicity. It's still early in development but I decided to release an early alpha version and hopefully get some feedback from anyone that might be working in a relevant field. There are several directions I could take, but what would be the minimal set of features that would make this tool useful for you? Any feedback is welcome!

Isn’t 3 frames of latency already way too much? I would say they are both too slow!

Perhaps for understanding the structure itself, but having the structure available allows us to focus on a coarser level. We also don't want to use quantum mechanics to understand the everyday world, and that's why we have classic mechanics etc.

Also similar to temporal antialiasing https://en.wikipedia.org/wiki/Temporal_anti-aliasing .

I don’t completely agree with Rossman here. You are buying the streaming right and not the file. What I agree on though is that they don’t make that clear to their customers.

This. I used to be a multi monitor type of person but when desktop switching became good (I first experienced this in Linux) I started using a single larger monitor and never looked back.

I hadn’t come across the this before, but in Dutch we have the oer- which is spelled out as in poor, so I somehow connected the dots.

New comment by Grieverheart in "Dreams are the default for intelligence"

Grieverheart — Fri, 14 Apr 2023 22:25:44 +0000

I once trained myself to recognise if I was dreaming by looking at something in my dream, looking away and looking back again. If the thing I was looking at had changed in any way, I was dreaming. This allowed me to partly shape my dreams, so I can’t totally buy the conjecture that senses are what’s taking the dream machine. Another thing supporting this is the fact that I could let my body fall asleep while keeping my consciousness awake. Even though the senses are technically shut off (sleep paralysis), I was not dreaming. I think the fact that dreaming is similar to generative models has more to do with how we learn shapes, and that is by learning sub shapes and categories of shapes. My theory is that that’s also how long term memory works. Instead of storing the full senses senses at that moment, parts of those senses are replaced by concepts/sub shapes.

Nothing beats Safari in terms of battery usage, and there are features like the reading list that work really well (for me). For development, yes, I always have Chrome installed in case I needed it.

Grieverheart — Tue, 08 Feb 2022 10:32:36 +0000

This is also the reason many companies rewrite code to new framework because they cannot find developers that know how to program in the old framework. Really narrow-minded if you ask me. You just need a good programmer than can easily learn new languages/frameworks. It might take a good programmer a week to learn a new language/framework.

Naturally I came across Jerobeam's work while conceiving the visuals of my game. You can read more about the process in my blog post http://nicktasios.nl/posts/in-search-for-creativity.html

The paper is a bit over my head. Are there any findings with respect to the phenomenon of Deep Double Descent [0], or the more recent grokking phenomenon [1]?

Thanks! I have already read the 8bitworkshop one, but I was on vacation back then so I couldn't get my hands dirty. The samples are also definitely going to help. I do like the approach of using something like Verilator, though. The barrier to entry for actually doing stuff on the board seems too large for me at the moment -- Need to install and learn software (Quartus), and my everyday computer is a Mac so I have to use a slow VM!

I also have a DE10-nano for running MiSTer cores and I'd like to learn to program the FPGA. Do you have any recommendations on getting started?
