jessfyi··on Large Language Models Encode Clinical Knowledge
Tested against dataset consisting of only multiple choice questions and was only able to achieve 67% accuracy on MedQA (the medical licensure examination.) LLMs alone are not the way forward in this area (and in this instance not generalizable, nor capable of handling necessary edge cases the job demands.)

These are far inferior to professionals and just like what we saw with Watson, hyping them up as job replacements or assistants when they're clearly not up to snuff is not only foolish for the perception of the industry as a whole, but wildly irresponsible.

jessfyi··on Dwarf Fortress – randomly generated, persistent fantasy world
The version being released on steam also includes extensive UX/UI updates, OP just left that out.
jessfyi··on Removing SMS support from Signal Android (soon)
The idea that they can't improve the UI/UX to better inform to the people who repeatedly, accidentally send insecure messages/sms (ignoring the existing words "Unsecured SMS" in the chat field, the unlocked lock near messages, the unlocked lock next to the phone, or the giant banner that occasionally drops down that tells you the % of secure messages you can be sending if you pester a contact into grabbing signal) as one of the reasons for this change is frankly bullshit.

Changing the Send button's icon to "SMS" or a color/border change ala iMessage are ideas off the top of my head and I'm sure they've got designers significantly more talented than I am that can think of better ones. We've seen very little iteration there that's indicated the significance of that problem...and frankly if they highlighted this as a tactic vs endless spam texts more people would be receptive to this news. As it stands I think this is going to significantly reduce their number of casual users. In fact I'm willing to bet that the cohort of users who are used as justification are the least likely to convince their contacts to switch to Signal.

Don't get me wrong, their real desire to increase the amount of people sending secure messages via Signal alone + resource mgmt in the face of a recession are valid. But acting as a unified messenger (with better link unfurling, threaded replies, and reactions after Google killed Allo vs the default messenger that spent years getting them) was the trojan horse onto many of my friends' and colleagues' phones. Now that there's parity I can see more people just opting into the default messenger/FB Messenger + Whatsapp combo because more people exist there and we're all just lazy.

jessfyi··on AWS doesn't make sense for scientific computing
I've followed Hail and applaud the Broad Institute's work wrt establishing better bioinformatics software and toolkits so I hope this doesn't come as rude, but I can't imagine an instance in a real industry or academic workflow where you need 300ms feedback from an experiment to "maintain flow" considering how long experiments on data that large (especially exome sequencing!) take overall? My (likely lacking) imagination aside I guess what I'm really saying is that I don't know what's preventing the usecase you've described from being performed locally considering there'd be even less latency?
jessfyi··on GeForce RTX 40 Series
These prices are beyond insulting and frankly I'm glad they're going to take a hit competing with the flood of miner cards entering the market.

Also note that nothing is preventing Optical Flow Acceleration [0] (and subsequently the DLSS 3.0 models that they claim are exclusive to the 40 series) from running on either 2/3 RTX cards. Just like RTX Voice and other gimmick "exclusives" I expect it to be available to older cards the moment they realize their backlog of 30 series cards aren't clearing as quickly as they thought.

They're competing against an over-bloated secondhand market, AMD, Intel, much better integrated GPUs, and comparatively cheaper consoles that maintain sky-high demand with subsidized games via new subscription programs. They're vastly overestimating their brand loyalty (think Microsoft v Sony after the 360) and EVGA's exit makes more sense now than ever.

jessfyi··on Ask HN: What are the best-designed personal blogs you’ve come across?
https://maggieappleton.com/ for her take on a digital garden. She also compiled more below [0] if opening your thought process to the public is your thing (adopting the concept actually got me to add more structure to my serious notes and actually post more)

https://brianlovin.com/writing/how-my-website-works because of how in-depth he went with hosting his notes, bookmarks, and other projects.

https://wattenberger.com/ for its reactivity/place for her d3.js experiments.

and here is a general collection of dope blog additions: https://brainbaking.com/post/2022/04/cool-things-people-do-w...

My overall advice is unless you're a designer flexing your skills is to focus less on the design and more on the actual writing! The internet is littered with the emaciated husks of nice good looking sites hosting nary an entry beyond "How I Made My New Blog With X"

jessfyi··on Most Texans pay more in taxes than Californians, data suggests
I mean your "data" will be particularly skewed towards one end of the argument seeing as you deal with people with millions and are literally incentivized to note it as a bigger problem than it is. Differences in housing and job availability are bigger differentiating factors when "normal" people decide to move.
jessfyi··on Julia 1.8
No, because of lack of progress in areas I care about. It's just a tool that currently doesn't fit my most crucial needs, so I picked up other tools.

The discussion was further evidence of the reality that I'd already come to terms with; the lack of inroads in building a larger community and general ecosystem is partly because of a lack of focus on things like tooling, linting, documentation standards, etc and partly because of a weird amount of disdain for the language. I can help with the former, but I don't have the time or energy for the latter because it's actually a set of large, long-term marketing, organizational, and psychological problems to overcome. Maybe someday down the road I'll be back, but I've given it a shot for about 8-9 years now.

jessfyi··on Julia 1.8
I mean if you go through them yourself and you'll see most (if not all) of those are closed. And the majority of the others dealt with composability issues between custom packages/libraries and not base Julia. Honestly it's a tooling + linter problem, and the lack of progress there (plus the general adversarial/celebratory tenor of that thread) made me pretty glad I've just moved onto Rust + python again. It's just too demoralizing from a dev's perspective to see.

Don't get me wrong, I love multiple dispatch and Julia's composability + speed make it a no brainer for science/quant econ teams to adopt (and using it to train models on TPUs is a actually a sneaky way to save time + $), but they've lost the "culture" war and I can't see the entrenched masses here or elsewhere changing their minds on it. Not sure whether it's for job security sake or they got sick of all the "Julia is faster than/will replace X" evangelism or Plots loaded too slowly the one time they tried it years ago or a combination.

jessfyi··on Show HN: Search engine for finding the best of anything
Love that more of these little search alternatives are cropping up. Try suggesting search queries that do perform well on the page or as a watermark in the search box if you're currently that limited. One thing that definitely turned me off were the silly graphics over the picture under the privacy pledge; it makes it look like a joke when it should be serious because people who care about it really care.
jessfyi··on Open-source rival for OpenAI’s DALL-E runs on your graphics card
Hasn't been updated since 2020, but Tim Dettmer's guide [0] is pretty much the gold standard for optimizing what to buy for which area of DL/ML you're interested in. The pricing has changed thanks to GPU prices coming back down to earth a bit, but what to look out/how much ram you need for which task hasn't. Check out the "TL;DR advice" section then scroll back up for detail info on why and common misconceptions. For the tips on a RAID/NAS setup alongside it, just head to the datahoarders subreddit and their FAQ.

jessfyi··on I wish I could organize my thoughts
I'm so tired of these "infinite canvases" being proposed as solutions for organization without any second thought to how you'd retrieve any information. Minimaps are a possibility, but there are no shortage of ways to get ideas down both linearly and nonlinearly.

I thought the Zettelkasten hype would show more people that when it comes to organization and notetaking we need better ways to get things out than in. And when comes to the idea of "automatically linking" notes and ranking concepts within those notes based on importance or value there's no such thing as "one size fits all." Ideas and innovations in that area, maintenance, search, and surfacing relevant (forgotten) notes are far more interesting problems.

jessfyi··on Emoji Kitchen
The magic wand turning emojis into their old blob-style representations (https://en.wikipedia.org/wiki/Blob_emoji) is actually an amazing little easter egg.
jessfyi··on Former U.S. congressman, operative pleads guilty to election fraud charges
It becomes a partisan issue when one party conflates the two in order to write and pass laws to disenfranchise voters under the false pretense of securing elections while people parrot their (erroneous) factoids and talking points.
jessfyi··on Former U.S. congressman, operative pleads guilty to election fraud charges
Except the entire process was being recorded and that never happened. https://www.reuters.com/article/uk-factcheck-philadelphia-po...

Love how temp accounts can post partisan hackery (and post a comment noting they have an obvious agenda), so we get to hear all the old, lame conspiracy theories from twitter on hn.

jessfyi··on OpenAlex: The Promising Alternative to Microsoft Academic Graph
Meta only focused on biomedical information. This is explicitly based on Microsoft Academic Graph which was all encompassing. They did remove patents, tag papers with fewer topics/subtopics, and don't index as many conferences, but they did add a couple of nice things like ORCID. [0]

jessfyi··on Sony AI and Gran Turismo developer announce new groundbreaking racing AI
I would've linked the Nature article and study[0][1], but of course it's paywalled. The blog does however have a video of Emily Jones finding new lines with it, and I've seen her put in some stunning times in both iracing and GT Sport.

EDIT: Oh and here's [2] a (long) video of the agents in action...their racing lines and aggression are genuinely impressive.

jessfyi··on Ask HN: What Has Happened to Twitter?
Nothing about this requires blockchain. There are plenty of Twitter archive sites like nitter.net that are not only open source, but also have plenty[0] of distributed instances on good old "web 2"

jessfyi··on Parrots will share currency to help their pals purchase food (2020)
I wasn't aware ETH Zürich was considered the Ivy League!

But all jokes aside I think you should give these professionals a little more credit--they also factored that possibility into their experimental design and included tests for "useless" token transfers [0]. While parrots would often transfer tokens to empty compartments (for when they knew their neighbor was missing and lacked tokens), these same parrots did not when there was a completely empty partition [1]. Further even the article notes they didn't just hand out tokens automatically or willy-nilly, but were more or less willing depending on the bond.

Personally I think the most interesting thing about the study is not that non-mammalian animals have the capacity for altruism or prosocial behaviors, but that Blue Headed Macaws (despite being extremely intelligent as well) were not willing and the difference is that their general populations form smaller (though equally cohesive) flocks compared to AGPs.

EDIT: and the reason why they used tokens vs direct walnut transfer is that these birds were trained in a prior experiment (with an equally interesting premise) [2]

jessfyi··on Modern mainboard for traditional T60 ThinkPad
As someone who's gotten both X2100 and X300 mods from Xyte (a much smoother process than what originally was dropping 1k+ into a random person's account on a forum and hoping you actually got your custom motherboard months later) I just love that they're still trying to expand on this concept and recognize the lasting fervor around OG Thinkpads.

Personally I just want a Ryzen-powered mainboard, but figure there's sourcing reasons for why they're sticking to this intel generation.

jessfyi··on Chan Zuckerberg Initiative sunsetting science research platform meta.org
Regularly check on meta, saw the announcement, and figured they'd change the name so they can transfer the .org and .ai names to the main company. Didn't expect them to just shutdown the team altogether. With their May/June updates (where they started to track and index beyond just papers) I thought they were actually onto something.
jessfyi··on Chan Zuckerberg Initiative sunsetting science research platform meta.org
Uh meta is (was) just a version of Google Scholar with an emphasis on biomedical publications and better tools for scientists and clinicians to keep track of it all. Not sure that warrants your conspiratorial rant?
jessfyi··on Raspberry Pi Zero 2 W
Ah thanks! I also just realized other vendors would likely ship later. Wish they mentioned them in the official blogpost as well.
jessfyi··on Raspberry Pi Zero 2 W
The US vendors linked on the official site sold out in less than an hour...really wish they enforced a limit per person like pihut did. Anyone else starting to notice that buying any new tech on launch with enthusiast levels of hype (the past 2 years, even prior to the supply chain slowdown) requires spinning up a bot?
jessfyi··on Connect: A New Chapter for ReMarkable
So they've increased the price for their "pro" stylus which you need to erase (now the same as the 2nd gen Apple Pencil), their screen sharing has a large border to accommodate their logo, and the only way to get your handwriting converted to text (one of the key features they've advertised since the days of RM1) is to pay for $8/mo plan.

I don't see any reason why a company or school would buy these over iPads (guessing they're banking on outlets not updating their already middling reviews and the "discount" obscuring these changes). I'll personally grab Sony's new e-ink tablet, but I'm still holding out hope for another company to jump into this space with a competitive product for general employees/consumers. Frankly, the quality of the RM2 isn't good enough to justify this kind of "premium" subscription service.

jessfyi··on Star Citizen Progress Tracker v1.0
I don't know how you can seriously mention Freelancer without mentioning that it was completely taken out of the over-promising grip of Chris Roberts. Great game, but I despise the fact that people attribute the work of those programmers who worked to actually put the thing out (when he got his golden parachute and all they got was more crunch) to that huckster.
jessfyi··on Ask HN: College name vs. education
In terms of CMU, I'd say your first point is short-sighted. Because of the relatively large Design/Art, Architecture, and Business programs, the generic freshman orientation/prereqs, a surprisingly inclusive Greek presence, and the small social scene there's plenty of opportunity for mixing with different people.

In fact, I'd go so far in saying that meeting people outside of your typified social circle isn't institution dependent, rather an individual preference (so I wouldn't be surprised if your generalization isn't applicable to MIT either).
