justsocrateasin··on How to run 50% faster without external energy (2020)
This is true for certain metabolic zones but not others. If you're sprinting then yes, you get a higher power output while pulling up on the pedal. However if you're going for any kind of endurance (longer than a minute) the limiting factor is not muscular but cardiovascular/aerobic, and using less efficient muscles (the ones used for pulling up) will actually hinder your performance since you'll need to be supplying those with oxygen, thus decreasing total cycling economy.

justsocrateasin··on "Nepo-homebuyers": 38% of young buyers use family money for down payments
Confused why you don't think this is a problem?? just because family will be there for you when no one else will doesn't mean they are financial liquid enough to support you with $50,000-$100,000 in cash. Clearly that is your situation but for the VAST majority of Americans that is not the case.

Average home price in America is over $400,000 which means a 20% down payment is $80,000.

justsocrateasin··on Washington, DC, avoided the worst price rises that have plagued American cities
> DC is horrifically expensive for a small city.

Fully disagree. I lived in a very nice 2bd/1ba apt with a friend just two years ago and paid $1200/mo in rent.

> If you're going to live in Arlington it begs the question of "why even live there unless you have to".You could probably live anywhere else since the character-less high rise apartments and strip malls are copy and pasted for every other new development style in the country. I was just in Bellevue in Seattle and for all I knew it could have been Arlington.

Wow. I disagree so hard here. As someone who grew up in Arlington, sure I'm biased, but also educated on what Arlington is like - there are incredible diasporas from Korea, Mongolia, East Africa, and Central America. Really excellent food, a lot of culture spread throughout. Public school system is amazing, and you're 1.5-2hrs away from some amazing national parks. Sure - it's still a suburb. The Rosslyn/Clarendon strip has some spots that fit the description you're talking about, but also some spots that totally don't. It brings a lot more to the table than most other suburbs I've been to.

justsocrateasin··on I Paid Off $194k in Student Loans in Six Years. It Wasn’t Easy
Congrats!

It feels so good. I paid off about $60k of debt in 1.5 years after college while living at home. It was hard but worth it.

justsocrateasin··on Dementia risk linked to blood-protein imbalance in middle age
Exciting pieces of research coming out right now. I could see using a blood test to find these specific biomarkers, and then getting started earlier on a drug like donanemab that has better results the earlier you start it. Combining a blood test with a preventative/early stage drug like donanemab or lecanemab would have a lot better results than just starting those immuno drugs at the first sign of symptoms.

Reminiscent of a very interesting company I interviewed for last year called Cache DNA

https://www.cache-dna.com/

This is the future. I don't think it will look exactly like this, and I don't think it will be here any time soon, but I'm excited to see these advancements.

What Cache is doing presently is trying to do archival storage in DNA - it has a lot of potential to be cheaper, more energy efficient, and more redundant. But some of the processes still aren't there yet.

justsocrateasin··on Backend of Meta Threads is built with Python 3.10
Could you describe your tech stack more?

I'm a data engineer trying to teach myself React so I can build a full stack app using some APIs and it's certainly a good exercise, but I could also certainly build that in Python. Your app looks great and I'd like to explore that more!

P.S - fellow runner and cyclist and out and I'm checking out the app more now.

justsocrateasin··on Ask HN: Are people in tech inside an AI echo chamber?
Humans are likely to share when they don't know something or to express concern when they aren't positive what they're is correct. LLMs are confident 100% of the time and don't understand when they're wrong. I get what you're trying to say but I don't think this is an instructive example.

both work! I actually think `floundering` works better in context - "men breaking down" versus "men struggling".

justsocrateasin··on The Leverage of LLMs for Individuals
Well, obviously - you need to make money. So if you're not getting paid at your current job, many people can't afford to stay at their current job. If I had UBI or some kind of trust fund, I might stay at my current job. I really do enjoy it and think I'm better off with the structure it provides me.
justsocrateasin··on The Leverage of LLMs for Individuals
I really liked this article overall, but was very confused by this section -

> If you are an individual developer, the leverage it provides might be 10 times greater, but when you work for a company, that number might be only 2.

Where do these numbers come from? Did ChatGPT hallucinate them? I don't understand why both can't be true. Why can't I have 10x leverage in my job and use that productive to unlock more time and then further leverage myself as a personal developer? Very strange sentiment here and also a baseless claim IMO.

justsocrateasin··on Googlers angry about CEO’s $226M pay after cuts in perks and 12,000 layoffs
I don't think this is a good argument. Just because you are at a cost center/not at a profit center doesn't mean you don't have any connection to the profit.

Take HR. Total cost center. By this logic they shouldn't get any piece of the pie. But in reality, without *good* HR, a company can be a shitty place to work. HR is just one example. Many others out there.

justsocrateasin··on US could soon approve MDMA therapy
OK but I don't think chalking it up to 'weather-related reason' is entirely accurate either. That may make up a portion of it [1] but it doesn't make up all of it [2]. And I agree that the US has a high prescription culture, but you could argue too that this is an artifact of having an exceptional health care system by most metrics. Mental health disorders are complex with a multitude of causes and it's rather reductive to say that they're due to "the social aggression inherent in US life".

If this is the case, why don't we see long covid symptoms in certain professions? I spent an internship working in a clean room wearing full PPE including an N95 mask for my entire 9-5. Didn't ever experience long covid symptoms.
justsocrateasin··on Why is sea level rise worse in some places?
Seeing a lot of people talk about how the density of water is going to change with a temperature change. I don't really think that's true. Liquid water density is pretty darn inelastic and almost fully incompressible. It's one of the reasons hydraulics works. Ice on the other hand has a pretty different density.

Water density table - https://www.usgs.gov/special-topics/water-science-school/sci...

If the temperature of the ocean changed by 10°F that would result in a .1% change in overall volume. Obviously that does make a difference because the ocean is so big, but it's a lot less consequential than ice, which is above the water, melting into the water and ice.

justsocrateasin··on Why is sea level rise worse in some places?
Water density is almost fully inelastic w/rt temperature. At 60°F the density is 0.99907 g/cm^3, at 100°F the density is 0.99318 g/cm^3. I think that's something like a .5-1% change in density. Pipes bursting is purely because of the drastic density change from ice crystallization.

not comparable from a climate change perspective, but helps put perspective into just how much CO2 that is. I disagree with you that it's unhelpful, context is always helpful.

justsocrateasin··on UK: Food inflation rises to 18.2% as it hits highest rate in over 45 years
IIRC deflation and inflation are equally as bad. If 'inflation' rates are negative, the economy grinds to a halt. Having an inflation rate of ~2% is widely considered to be beneficially for everyone, since it's in a 'goldilocks' zone, it creates stability.

Inflation of 4% sure isn't as good as 2%, but generally speaking the inflation rate in the UK appears to hover around 2-3% during "stable" periods. https://www.macrotrends.net/countries/GBR/united-kingdom/inf...

justsocrateasin··on That plum job listing may just be a ghost
I've found that there are two approaches - shotgun and sniper.

Shotgun approach - figure out what software speciality and industry you want (for me, it's Data Engineering in Biotech/anything life sciences), and apply to every single job that you seem fit for. I applied to 20, heard back from 2-3.

Sniper approach - if you find a job that you actually really want, work your network as hard as you can. Find a friend who is connected with the company, ask them to make an introduction. Find random people at the company, LinkedIn message the hiring manager, do anything you can to get an interview. Once you get an interview, you have a chance, but the hard part is getting the interview.

Not true. What statistics do you have here? I've been following Jonathan Haidts substack and he researches this extensively. https://jonathanhaidt.substack.com/p/social-media-mental-ill...

He cites multiple studies that talk about how the same trends are going on in other countries, and the same trends are occurring under similar timelines in places that receive high speed internet.

justsocrateasin··on Work less, get more done: Analytics for maximizing productivity (2009)
I totally agree, but OOP said that they refuse to play the politic games. I don't see how you can be 1) a top performer, 2) refuse to politic, and 3) not work hard. I think that's a "pick two of these three" situation.
