Short of frequent blood donation, is there any reasonably adoptable life change a person can make to meaningfully reduce expected PFAS intake, or is it best to try not to think about it?

Ha55ii's powder game is perhaps the best of the genre, and the ease of sharing made for a pretty cool online community circa 15 years ago. I remember various calculators / computers created in powder game, along with a bunch of artistic efforts.

Though I agree that inequality is less important than the quality of life of the poorest people, this article explicitly tries to characterize the latter, so even though this is done in the name of discussing wealth inequality, I'm not sure your comment applies here.

I was just starting a comment on this but you beat me to it! I believe

  contain: strict;
on the parent element would have been sufficient here.
How does this compare to relace, which I believe is also a YC company? They seem to have very similar functionality [0]

The linked article covers this - the main innovation is neither the HIV activation treatment nor the general mRNA-wrapped-in-lipids (LNP) delivery mechanism. Instead, it's a new form of LNP which works on specific white blood cells that were hard to target before.

  It was “previously thought impossible” to deliver mRNA to the type of white
  blood cell that is home to HIV, said Dr Paula Cevaal, research fellow at the
  Doherty Institute and co-first author of the study, because those cells did
  not take up the fat bubbles, or lipid nanoparticles (LNPs), used to carry it.

  The team have developed a new type of LNP that those cells will accept, known
  as LNP X. She said: “Our hope is that this new nanoparticle design could be a
  new pathway to an HIV cure.”
I built a similar thing that includes forces between particles meant to simulate a sort of fluid or, as you scroll down, a gelatinous solid. There’s a bit of free energy injected to keep things moving so it’s actually a very bad fluid sim, but I think that makes it a better interactive toy in exchange.

One of the fun parts of naively n^2 particle simulations is trying to find ways to reduce the algorithmic complexity of collision detection. I remember messing with sweep lines and similar, though I don’t remember what optimizations made it into the final code. [0]

I have a particle simulation type thing on my website: https://omrelli.ug/

It was supposed to be a fluid simulation, but it’s slightly broken in ways that I thought made it more fun. I made as a hobby project many moons ago.

These days there are similar looking things you can add to a site with a line or two of includes, but I think mine remains a little more sophisticated.

It’s interactive, and scrolling changes the simulation parameters.

Re:Manifest v2 is now removed from Chrome canary on Friday October 11, 2024 @03:04PM (#41812422)
I've finally switched (back) to firefox today.

I switched from firefox to chrome for their superior devtools a few years back, but hopefully firefox has had time to catch up.

Everything old is new again!

I'm not super familiar with KYB, so it could be that this would pass a human check as well, but I got in with a couple of mostly-blank utility bill / AOI templates and a pastebin saying 'this is the company x website, we do business y' as the official company website.

In any case this is a cool demo, and the type of thing that I expect to be mostly solved as LLMs get better. Good luck!

Re:FTX bankruptcy examiner's report [pdf] on Thursday May 23, 2024 @06:51PM (#40460846)
If you generated this with an LLM, you might consider labeling it more clearly. Wrote copy-and-pasting of llm outputs seems contrary to the ‘thoughtful and substantive’ north star of hacker news comments. And just in case I’m wrong, apologies - it would be a good bit of irony if I turned out to be the one hallucinating.

For the intrepid, especially those annoyed with the purported input-sluggishness of musescore et al, an interesting text-based alternative is LilyPond https://lilypond.org/

My dad wrote an opera using LilyPond in vim, though I believe these days he's actually doing more with supercollider, which skips sheetmusic and goes right to sounds: https://supercollider.github.io/

Re:My ranking of every Shakespeare play on Thursday June 22, 2023 @06:48PM (#36440252)
This Voltaire quote is misleading. He continues: “… one would imagine this piece to be the work of a drunken savage. But amidst all these vulgar irregularities, which to this day make the English drama so absurd and so barbarous, there are to be found in Hamlet, by a bizarrerie still greater, some sublime passages, worthy of the greatest genius. It seems as though nature had mingled in the brain of Shakespeare the greatest conceivable strength and grandeur with whatsoever witless vulgarity can devise that is lowest and most detestable.“

So while he is pointing out the crassness of the work, he does think it’s great. Voltaire was very interested in the English, and pointing out the contrast here was definitely coming more from curiosity or even admiration than from dislike.

Farallon Capital | Full Stack Software Developer | Full-Time | San Francisco ONSITE | https://www.faralloncapital.com

Join a small team including me and https://news.ycombinator.com/user?id=antimatter15 [0]!

We're working on an ambitious software project to revamp the investment research and monitoring experience at a storied financial firm with $40 billion of assets under management.

We iterate quickly, in close consultation with our users, and typically deploy multiple times a day. Our day-to-day challenges include implementing complex financial concepts and interfacing with everything from legacy financial software to cloud-based apps and services. We develop on Windows but come from Mac / UNIX backgrounds, and favor a more functional-programming style, though we value flexibility over dogma.

Most of our codebase is in Typescript/Node.js/React (excepting a few python components and some C# code that talks to Bloomberg).

We're offering all-cash comp (base+bonus) competitive with FAANG total comp at similar levels, with great benefits.

No idea if this could be financially viable. It’s essentially free to host so profit hasn’t mattered much so far.
Re:Show HN: WallSmash – An Infinite Brick Breaker Game on Sunday January 16, 2022 @06:07PM (#29961366)
Hi HN! A few friends and I created WallSmash years ago for our own amusement. We've been occasionally tweaking it ever since, and recently it has picked up a few regular players.

Probably the most interesting parts were working out the collision physics to be frame-rate-independant, making the drawing loop, and playing with the particle effects on collisions. Happy to answer any questions or entertain feature requests here :)
