Reproducing this cheap optogenetic rig to control e. coli gene expression using light.

Thanks, this is very valuable. I sent an email.
Interesting, I think the point about processing with GPT is important. Our thing started as naive narration but many articles are hard to follow when simply narrated.
Hey, we're working on this!

You have to add articles yourself and it does not have any special logic for HN threads yet.

Hey, I'm building something related and would love to get your feedback on it. I can reply with my contact details if you're interested.

We had to restream server events from openai -> our backend -> client. It was pretty simple.

You can return log probs per token generated. This can be used to asses the confidence the model has in handling tasks which involve nominal data.

If that’s not helpful, were you getting at having the model return some rich data about the attention weights that went into generating some token?

They seem to achieve the 'multimaterial' label by soaking different parts of the polymer in exclusive precursors. If you want to create advanced microelectronics using this method, you would probably want to be able to control gel-differentiation process as part of polymerization.
Re:Bonsai Browser is now open source on Friday July 01, 2022 @09:02PM (#31954975)
Whenever I start a project I usually look for some open source equivalent for inspiration even if it's not maintained. We opened up bonsai in case someone else comes along and wants to understand how we did a few things. There are some fun hacks we had to do to make certain things work around overlaying the main window on macOS that might be helpful for other electron apps.
PropelAuth is great and a breeze to integrate! We were dreading building out B2B features like orgs and spending time making login flows for our analytics dashboard product. This was all provided out of the box with Propel.

You can tell Andrew uses it himself from the practical docs and providing nice things like express middleware. I imagine it must be a bit mind bending to dogfood the service.

This seems like a step in the right direction away from sphere-projected 'immersive' video. Very cool and can't wait for the 6dof VR player to be ready!
Re:Ask HN: Why is UI design in Unity so hard? on Sunday February 20, 2022 @08:21PM (#30410938)
We embedded a web browser and wrote our UI in React for a previous VR project :)

Zenith VR might fit your definition of MMO like 3D game.
Re:Session-lived Application Backends on Thursday January 27, 2022 @04:06PM (#30106683)
This looks like the sort of thing we would have needed to build ourselves to take a remote control pixel streaming project from a while back into production.
Re:Yet another hot take on “folders versus tags” on Monday January 24, 2022 @04:56PM (#30064614)
Maybe we can add anon accounts at some point. The main reason right now is to make the feedback process easier since it starts an email chain that we can follow up on. All of the best improvements recently have started with these email chains and follow on conversations.
Re:Yet another hot take on “folders versus tags” on Monday January 24, 2022 @04:17PM (#30064176)
Check out Bonsai Browser [0] if you want to see what a web browser built on tagging rather than folders looks like (disclaimer: co-founder).

I think the main virtue of tagging systems is in the low friction to add info and multiple inclusion.

Tagging also has its downsides and I think we'll probably end up on some hybrid system in the long run.

I take it that you prefer FF over Brave?
Re:An Introduction to Lagrange Multipliers on Sunday November 21, 2021 @11:34AM (#29297499)
One application of Lagrange Multipliers includes deriving the micro, standard, and grand canonical ensembles from statistical physics [0].

These can be used to simulate physical systems like magnets and particle fields.

The Lagrange Constraints are used to constrain things like probability, energy, and particle numbers. What is constrained accounts for the difference between the ensembles listed above.

The derivation of the Support Vector Machine also involves Lagrange Constraints as well!

I'll look into this. We could bundle a terminal emulator like Hyper easily. Ideally we could get access to some sort of frame-buffers for other applications. I wonder how much control apple lets you have.
Re:Show HN: Web browser to help programmers think clearly on Monday September 13, 2021 @08:13AM (#28510486)
One of the things that I found interesting was that as you become more expert in a field you take less notes. At the start of your PhD everything is new but by the end you know the name and research group of everyone in your field.

What does not go away is the need for a flexible and low friction way to collect and organize things like journal articles. Some sort of mental ontology about your field replaces the need for actually writing lots of stuff day to day.

Re:My Room in 3D on Sunday September 12, 2021 @10:42AM (#28501576)
It can be both art and programming! Here's a paper showing how programmers work with artists to develop the classic TF2 half lambert [0]. This shader also makes use of an efficient method for representing diffuse environmental contributions using low order contributions on a spherical harmonic basis which is similar to techniques from quantum mechanics [1].

If anyone's interested, it is likely that the missing traffic is coming from people with blocker scripts that prevent analytics. I've moved the media files from the landing page over to a S3 bucket behind Cloudflare as suggested.
Re:Show HN: Web browser to help programmers think clearly on Friday September 10, 2021 @01:46PM (#28484900)
We're hosting 15mb of video files on that landing page. Netlify says we've had 2.2 TB of transfer out but dividing those numbers gives many more uniques than we've seen in the landing page analytics :/
Re:Show HN: Web browser to help programmers think clearly on Wednesday September 08, 2021 @09:36AM (#28456735)
I'll edit the readme of that repo to make it more clear. We're distributing the browser off of github so we don't have to pay for download bandwidth and because it integrates with our CI.

Our website got 1TB of traffic yesterday (which it turns out I have to pay for) and thats without hosting the binary on our site!

I use a mac so bugs get caught quicker in that version. The Linux and Windows builds are comparatively buggy so we did have not launched them yet.

Here's a cook UX project [0] that shows a potential UI-free operating system like you described.

Not right now. I'll add that to our todo list.

We've not added a hotkey for that, you have to press the button to the right of the url bar. I'll add a hotkey soon!
Re:Show HN: Web browser to help programmers think clearly on Tuesday September 07, 2021 @01:59PM (#28447769)
There's a link to a discord server on the bottom of the landing page. We'll post updates there.
