I have a graph with weighted edges. I want to remove edges to make the graph colorable with N colors (e.g. N=40) such that the total weight of removed edges is minimized. If I'm able to solve this problem, that will complete a project I've been working on for years now to make a working keyboard for a person I know that has cerebral palsy.

Graph coloring can mean vertex coloring, edge coloring, or total coloring. These are 3 different problems.

Regardless on the answer, I think this gonna be way too slow for your use case. Especially if you want the global optimum. Wikipedia says the current state-of-the-art is randomized algorithms, I don’t think these algorithms are looking for global optima.

I don’t recommend solving that, I think you’ll waste your time. How’s that related to the keyboard anyway?

I want to bring back old school distributed forum communities but modernise them in a way that respects attention and isn’t a notification factory. Mastodon is a pretty inspirational project but the Twitter influence shows, I miss the long form writing that was encouraged before our attention spans were eroded. Not at all close to solving it, but it’s been on my mind for a long time. Would love to hear if there are o…

I am building a project ( https://linklonk.com ) that does information discovery in a way that respects your attention. In short, when you upvote content you connect to other people upvoted that content and to feeds that posted that content. So to get your attention other users need to prove to be a good curator of content for you. I'm planning to do a "Show HN" post next week for it and would appreciate any feedback…

Seems good but the UI can be improved IMO.

I have two questions please:

- Is there a list of all the feeds used by LinkLonk?

- How many users are there today?

https://free-visit.net : Like Matterport but with an FPS game engine. I am looking for my first client: Ideally someone in charge of a Museum/gallery or other grandiose indoor space.

Agree with another commenter about camera height. Couple more things.

1. Your demo level suffers from Z-fighting in a few places on the floors and walls. https://en.wikipedia.org/wiki/Z-fighting

2. When viewed full-screen on a 4k monitor, textures are too low resolution. A handwritten note on the wall is unreadable.

3. Lighting is too simple. Because that’s not an FPS shooter you probably don’t need dynamic lightning nor day/night cycle, but it’s still hard. Ideally you need these multiple PBR textures everywhere, and correspondingly complicated pixel shaders.

I have posted this here before- hexafarms.com. I am trying to use ML to discover optimal phenotype for growing plants in vertical indoor farms to a. have the higest quality produce b. to lower the cost of producing leafy green/med plants, etc. within cities itself. Basically, every leafy green (and herbs, and even mushrooms), can grow in a range of climatic condition (phenotype, roughly) ie temperature, humidity, wat…

You need to sequence the plants otherwise you will waste too much time on tuning hyperparameters.

When and how are you planning to change your Terms of Use / Privacy Policy? That kind of information should be in the documents. Your privacy policy is currently insufficient. > We only collect your information for the purpose of providing this service. Okay, but what information do you collect? “Your information” is too broad; if you're collecting my retinal scans or matching me to a behavioural analytics profile, y…

I share your concerns about user privacy. The information LinkLonk collects is what you explicitly provide (ratings, etc) and the regular server request logs (which include your ip address, user agent). I clarified this in https://linklonk.com/privacy

I do want to add functionality to download your ratings. I'm thinking of exporting the ratings data in either the bookmarks format (ie, the format that browsers use to export bookmarks: https://support.mozilla.org/en-US/questions/1319392), csv or json. Please let me know what format would be most useful.

One time.

Also... is it possible for you to add nodes? Ie split a N>40 node into two nodes.

No, though nodes can be deleted -- at a cost equal to the total cost of all the edges that contain it.

I want to improve parts of online professional networking, specifically to be more about self-mentoring/shared learning, as opposed to sales connections. This is ever more important with the onset of remote hiring, remote work, and the isolation/depersonalization it brings to newcomers to the industry. There's also an "evil" momentum in remote hiring -- some companies _need_ asynchronous interviews to support their s…

This is a nice idea, to talk about and get thinking about these "soft" questions that people often struggle with. One feedback about the homepage: show a few examples of how people have answered questions, below the prompt. That's more helpful to get us thinking about our own answers, compared to a blank field. (Also, it's not clear what the percentages are meant to represent there. And I'm guessing the number next t…

Your guess is close! It is the total numbers, and the green/blue ratio indicate how many people answered the prompt publicly vs privately.

My intention was to show the general comfort level of answering the prompt in public. Looking back, I wonder if I was being too quirky.

I’m thinking the same on needing UI tweaks, I’m planning for major rearrangements.

Thank you for your interest. Please feel free to reach out via the contacts if you’d like an invite.

Do you have any specific suggestions on how to UI? Small tweaks would be most appreciated as I could implement them before the upcoming Show HN post.

To answer your questions:

1. The list of all feeds used by LinkLonk is not publicly accessible through the website. They are feeds that users explicitly submitted through https://linklonk.com/submit or feeds that LinkLonk parsed from the meta tags of the links that users submitted.

2. The number of active users has been about 4 for the last few months. I'm hoping to get it to 10 this year.
