sawaruna··on Erythrocyte omega-3 index, ambient fine particle exposure and brain aging
Not sure if I'm getting enough omega-3 as a vegan but hopefully. Eat quite a bit of nuts, and ground flax every morning. I take an algae-oil supplement for EPA and DHA, but not sure if there's some other easy addition to my diet.
sawaruna··on Worst- and Best-Case Scenarios for Warming Less Likely, Study Finds
For those looking for the changes: >The metric has existed for decades now. In 1979, a groundbreaking report led by Massachusetts Institute of Technology scientist Jule Charney—dubbed the “Charney Report”—suggested the planet’s climate sensitivity probably fell within a range of 1.5 to 4.5 degrees Celsius for a doubling of CO2.

>The new study narrows the range at both ends, particularly the lower end. It finds there’s a 66% chance that the sensitivity range falls between 2.6 and 3.9 C of warming (4.9 to 7 F).

Also the article mentions analyzing how the Earth reacts to change being a big reason for the update, particularly clouds:

>Perhaps most importantly, the new study investigates multiple lines of evidence when it comes to climate sensitivity. It uses global climate models, which simulate large-scale processes across the whole world. It also uses detailed, process-based models, which can simulate fine-scale events related to the formation of clouds.

>The new report devotes a large chunk of its analysis exclusively to clouds. It examines the growing body of science on how different types of clouds respond to climate change, and how changes in these clouds may affect future climate change.

Not only with clouds but feedback loops in general are the most interesting aspect of these predictions for me. I'm sure it's insanely difficult to calculate all factors, but I wonder how all-encompassing these models tend to be. The article mentions this being a type of meta analysis, but for a single study looking at clouds, for example, is the lowering of Earth's albedo due to melting ice typically something they would take into account when studying cloud predictions or not?

sawaruna··on I Switched from LastPass to 1Password (and You Should, Too)
I actually did the same, but then (as I commented on in a hn post yesterday[0]), I switched to BitWarden as I couldn't find anything that 1Password offered to make me want to pay for it over BitWarden. Not to say that 1Password doesn't have anything worth paying for, but for my personal use, BitWarden has been the ideal so far.

sawaruna··on An Introduction to the Resource Description Framework (1998)
I wouldn't say I have an uncommon take on RDF. I feel it gets more focus (maybe too much) in semantic web related academia and research than it does on the general web. And the substantial thing wasn't meant to be that harsh of a critique, but like another comment mentioned, sometimes these 'introduction / wiki articles about __' are a bit of a tease, and I wish someone were posting something more novel.

As for what I'm doing, it's a project that is taking various siloed fan-created data on the web and collecting, aggregating, and transforming it into RDF for the purpose of being queried by researchers. I think RDF and RDF-adjacent things (e.g. knowledge organization, ontology application) are useful here, but the actual querying / data analysis requiring an RDF transformation is maybe questionable.

sawaruna··on An Introduction to the Resource Description Framework (1998)
As someone still using RDF in research / work, always nice to see it pop up on HN. Even if it is nothing particularly substantial.

sawaruna··on Google's Recommendations AI now in public beta
>Recommendations AI is based on technology that Google says it uses to deliver recommendations on its own products, including YouTube and Google Search. The cloud company says retailers can use the tool to replace or complement existing recommendation models.

Hopefully some people write their thoughts on this after exploring the API. I have a rather general interest in algorithimic-powered recommendations when compared to human curated, so it should be interesting to see how this functions. This is assuming that, despite Google using it across a number of service types, Recommendations AI is not solely aimed at product purchases.

sawaruna··on Bitwarden second security audit report
BitWarden. Used to use 1Password, and while I don't mind paying for a service, especially a 'security' related one, I couldn't see the benefit over what I was getting with BitWarden.
sawaruna··on Bitwarden second security audit report
Good to see. Aside from the Apple ecosystem's password management, Bitwarden is what I've been using.
sawaruna··on GraphQL Query Generator
I'm working on a project right now that's applying RDF metadata schemas to some pop culture data, and while it's not GraphQL, the idea of random queries being generated is really interesting. Our output is aimed as researchers in certain domains, and while we have researchers onboard developing use-cases, the idea that some new ones could be imagined by viewing randomized queries sounds possible.
sawaruna··on Show HN: Dendron – a roam like open source markdown note taking app
These tools (this, foam, obsidian, remnote, supernote, etc.) seem interesting but I've been hesitant to try any. This HN comment[0] on a Foam post a few weeks ago resonated with me. I feel like my ideas and personal knowledge base in my mind is really dynamic and that the constant addition of information and rearranging or establishing of new relationships between entities will be too much effort.

I think, at least for my use, a more simply knowledge base (e.g. zotero, are.na, etc.) where I'm able to store, categorize, and search for things is the best option, and I'll leave the establishment of relationships to my mind.

sawaruna··on 'Doomscrolling' breeds anxiety – how to stop the cycle
It does and it's important and I'm not suggesting people purposely ignore it, I just don't know how you get to the point where it's saturated your social feeds so much that you get this kind of phenomenon. I get a lot of news or people posting political commentary, which I enjoy seeing, but it's also mixed in with a lot of music or design or game dev stuff or whatever.

Like another comment here mentioned, the diversity of content (and maybe slightly less political news) is why people like HN, so maybe I've just been lucky to be able to 'curate' my Twitter similarly.

sawaruna··on 'Doomscrolling' breeds anxiety – how to stop the cycle
Maybe people should utilize social media for things they enjoy instead of solely sources of news. Of course people you follow will end up posting news anyway but it won’t be solely stream of ‘doom and gloom’.

sawaruna··on Göbekli Tepe
People see Graham Hancock on Joe Rogan and think those are the extent of his beliefs. Watch his other talks where he ponders of ancient Egyptians used some kind of telekinesis to move stones and build pyramids.

sawaruna··on A man who can't see numbers between 2 and 9
In that second video in the article, he's holding a cutout of the number 9. I wonder if he put it on the paper and traced the outline, including the inner circles, what he'd see. Would the lines be accurate until the pen strokes connected to make an '8' and the result would suddenly scramble?

Also, is it the shape itself or the fact that the shape is a number? In other words, if you put a random cutout of the number 8 on a tree branch rather than have him look at a sequence of numbers, would that make any difference?

sawaruna··on Ask HN: How to deal with mechanical keyboard users in an open office plan?
Ask them to get a desk or keyboard mat. Alternatively get a keyboard with even louder switches. Model M, Gateron blues, Kailh Box Navy, etc.

I sure hope so.

sawaruna··on Ask HN: How do you store, index, tag papers?
Mendeley sadly. Something with a better iPad app would be nice.
sawaruna··on Study casts doubt on carbon capture
>"All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution," said Jacobson, who is a professor of civil and environmental engineering. "Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. Wind replacing fossil fuels always reduces air pollution and never has a capture equipment cost."

Isn't the idea to use both renewable energy sources AND co2 capture where possible? I'm not sure I've heard capture proposed as a replacement for renewable energy and that we should just continue using fossil fuels while capturing co2.

>This research is based on data from two real carbon capture plants, which both run on natural gas.

This is related to the last point. Assuming capture plants were run using renewable energy, I'm not sure if there is a net environmental negative from using both together.
