jyu··on Ask HN: Why aren't you starting your own company?
Opportunity costs get higher as your compensation goes up. Usually you don't start a company yourself, so you also need to consider your immediate network's increasing opportunity costs.
jyu··on Ask HN: Has anyone here successfully earning side income from an app?
I use side projects to figure out the next place to put my 100% full time effort. This way the side project does not need the unnecessary pressure of making money, having customers, a worthwhile use of time, etc.
jyu··on Ask HN: Did I make a mistake jumping on the homestead bandwagon?
Homesteading is a modern day algo trap. As a concept it's so tantalizing that once you watch one video, the algorithms feed you endless hours of other homesteaders pretending for the cameras, asking you to smash the like and subscribe. It's much like the tiny house movement, or van dwellers, or professional gaming.

Be suspicious of any hobby where there are hoards fat margin advertisers.

jyu··on Career advice nobody gave me: Never ignore a recruiter
You know how everyone hates real estate agents? Imagine if a real estate agent did not need to take courses, become licensed, and face repercussions for unethical and illegal conduct.

That's what a recruiter is.

jyu··on Urea prices increase 270% in 1 year
Real interest rates are still massively negative and will not change much if our total 2022 hikes are 1%. It seems like monetary policy will result in financial crashes (like you allude in that comment) or potentially even more inflation crashing certain assets upwards, or a slight possibility of hyperinflation.

Curious what odds you assign for each outcome?

jyu··on Ask HN: How do you validate demand for your side-project?
Don't overcomplicate things. Ideally you or someone you know is willing to pay for said product. Then you find other people like you or someone you know who are also willing to pay.
jyu··on You block ads in your browser, why not in your city?
Have you run into the IRL pop up ads? People walking in front of you, interrupting your UX for a quick "5 min conversation" about their chosen cause? These pesky ads get through my blockers no matter how often I update my filters.
jyu··on Reddit files to go public
If you thought site performance is bad now, wait a few quarters when there are grey beard investors pressuring leadership to wring out the last shekels from this carcass.
jyu··on Ask HN: Trying to explain NFTs to family on Thanksgiving – am I wrong?
You're wrong. Look at the history of digital gaming and people trading in game items for real money. Look at the whole swath of digital art, music, nba game moments, etc that could not be certified and now can be. Look at how major game studios were silent about NFTs and now all announced in their recent earnings reports that they are at least investigating blockchain and NFT and soon incorporating them into their futures. If you do any bit of shallow research, you'll stumble into several multi billion and soon to be multi trillion dollar market cap plays.

Look back at this comment in five years.

jyu··on What I learned from teaching the children of the 1%
If you have money it's easier to make many more meaningful bets. You don't need to aim for epoch changing discoveries, just use money to become a benefactor of them.
jyu··on Tell HN: I've been using Brave for a solid month
FWIW brave on mobile allows me to navigate websites without half the screen blocked by ads. Pages seem to load faster, battery life isn't randomly drained and helps avoid a lot of dark patterns found commonly on "news" websites.

Sure I guess some combination of pihole + vpn could also work, but using Brave is a lot less hassles.

jyu··on How Google designed its wildfire feature for Maps
Is there an alerts feature for this, similar to Ring neighbors?
jyu··on Ask HN: Is working on an old front end stack going to hurt my career
Front end is mostly a young person's game, and most subject to changes in fashionable trends.

React and Vue seem to be the current winners in this space. Prepare to retool yourself in these to pass interviews.

jyu··on Ask HN: Career progression vs. meaningful/appealing products?
All things equal, pick the areas with growth. Google, Meta, Amazon all have natural monopolies in growing markets where your individual performance doesn't matter that much. This is a safe play w good short term upside. AI, blockchain, security, etc are growing areas but you need to make an initial investment and maybe a lateral or down move to retool yourself and reorient your work network. This is the risky play with a lot more potential upside.

Life is short though, once your base needs are met, figure out what you want to work on and spend more time on whatever that is.

jyu··on Ask HN: Is web3.0 or Blockchain tech likely to disrupt centralized marketplaces?
Everyone in this thread so far says no. Existing marketplaces and companies have solutions to their problems. You need to look at important problems that can not be solved with standard tech and are trivially solved with web3 or blockchain. There are many examples if you look hard enough.
jyu··on Ask HN: Are the environmental concerns around Bitcoin serious?
The world is becoming and increasingly complex place and the amount of available information overwhelms the human mind. Instead of spending hundreds of hours researching a single topic, thinking through the points from different perspectives and context switching, it's easier to use mental models to take short cuts. The electricity excuse results from taking a few short cuts.

It's like saying in the 90's that electric cars will never catch on. The oil and gas companies will crush them before they even get started. Or an app that allows you to hail a car? Taxi companies are one of the most corrupt areas with the biggest lobbyists, you would have to be a total moron to try that. A cryptocurrency exchange in the US? Good luck keeping your bank accounts open.

Electricity consumption is a moot point. Bitcoin is here to stay.

Often times the best opportunities are when you have done your research and conclude the exact opposite of general consensus.

jyu··on Google to pay Apple $15B to remain default Safari search engine in 2021
If only I could pay Google $30 / year to opt out of their data collection schemes.
jyu··on Ask HN: Who’s the most underrated person in history?
Diogenes of Sinope. The more you read about him the stranger things get. Alexander the Great came to him and sought his guidance. Instead of being impressed and delighted by his request, Diogenes asked Alexander the Great to move to stop blocking his sunlight. Unfortunately, most of his primary sources have been lost besides "Lives of Eminent Philosophers." His stories offer great levity and fresh perspective.
jyu··on Regulators should treat stablecoins like banks
Paypal is not a licensed bank. Square, whose IPO was 11/19/2015, only got their bank license in 2020. Why should cryptocurrency be under the purveyance of banking regulations?

Cryptocurrency is pulling back the iron curtain and revealing the real Wizard of Oz when you consider unequal regulatory treatment and unequal enforcement efforts. Remember BOA robosigning fake mortgages and commiting widespread fraud? Remember HSBC getting slaps on the wrist for multibillion dollar drug laundering? Let's see how far this political doublethink and perverse incentive onion goes.

jyu··on Ethereum just activated its ‘London’ hard fork
To add onto this, is it so hard to imagine the US gov't asking coinbase, gemini, etc to stop payments from "terrorists" and block their transactions?

Where is censorship resistance when the on ramps and stakers become centralized?

jyu··on Ethereum just activated its ‘London’ hard fork
Is it so hard to imagine that the US gov't does not want coinbase, gemini, etc to process payments from "terrorists" and block their transactions?
jyu··on Ethereum just activated its ‘London’ hard fork
I asked this months ago and did not get any convincing answers.

Ethereum is currently decentralized because of the initial POW distribution. Won't there be centralized aggregators of eth so some point in the future a handful of POS nodes control a disproportionate amount of power? Is it so hard to imagine that coinbase or some other exchange accumulates enough eth to sway transaction validation?

Seriously, please answer if this is wrong!

jyu··on Andreessen on Crypto
The world and society at large has seen an erosion of trust.

For the naysayers, ask yourself:

- do you trust your government more or less than your parents

- do you trust the mainstream media more or less than your parents

- do you trust big companies to do the right thing more or less than your parents

As we culturally become less trusting, we need different tools to organize and determine value. Protocols that enable decentralized, distributed consensus helps build those tools. Adoption of these protocols, independent of cryptocurrency mania, is bound to happen.

jyu··on Analysis of blood markers predicts human lifespan limit
If you're new to this area of biomarkers and longevity, there are several people to follow with different approaches:

- David Sinclair Why We Age and Why We Don't Have To. Mostly focused on NAD+, sirtuins, use of yamanaka factors to reset epigenetic clock

- Horvath for horvath clock using dna methylation to measure aging in organisms.

- Michael Lustgarten a good curator for biomarker related research for longevity

- Rhonda Patrick has insightful scientific interviews and dietary and behavioral interventions

There's a spreadsheet with 9 biomarkers (with correlations) and age for Levine's Phenotypic Age floating around, based off this paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5940111/

jyu··on Ethereum will use around 99.95% less energy post merge
Maybe it is spread out now, but won't there be centralized aggregators of eth so some point in the future a handful of POS nodes control a disproportionate amount of power? Is it so hard to imagine that coinbase or some other exchange accumulates enough eth to sway transaction validation?

Seriously, please answer if this is wrong!

jyu··on How Big Tech got so big: hundreds of acquisitions
This is lazy reporting. Where did the money come from to do the acquisitions? Google and Facebook have great monetization by data mining their audiences for advertisers. All they needs is to buy more eyeballs (youtube, whatsapp, instagram, etc).

Amazon is slightly different. They benefit from the creative destruction caused by physical retail purchases migrating to ecommerce and the subsequent value capture by Amazon. Any revenue increase from them is from behavior changes, efficiency gains, and death of inefficient retail.

jyu··on Ask HN: Do you feel like the world we live in is increasingly speculative?
This is a US centric answer. We were taught that retirement funds and portfolios needed to outpace inflation to increase spending power. But inflation is not the right metric to measure against. Maybe the right metric is the percentage growth of the federal reserve balance sheet. Since it has recently inflated at a rapid pace, people are left with relatively much less purchasing power and facing economic uncertainty. We can not rely on conventional investments like real estate or the stock market to keep pace so you need to allocate a larger portion of portfolio towards more alternative (read: risky) investments.

Not too long ago the conventional wisdom was to stick your money in S&P 500, or a mix of stocks and bonds and forget about it. Bond real yields went negative. Bank savings rates are a pittance. While all that happened, indexers lost out on all the gains from TSLA until the end of 2020. More people are catching onto this regime change. Growing piles of money are chasing smaller pockets of growth in the same way the pool of well paying careers is drying up.

You can't get by with an average portfolio unless you have an above salary with above average savings. Stay tuned for more creative destruction ahead.

jyu··on Ask HN: How do solo devs get feedback on their code?
I used https://www.pullrequest.com just to pay someone else to look at my code and make suggestions. Aside from just the normal nitpick styling stuff, they usually have decent architecture suggestions and help you avoid making costly mistakes. It's not cheap, but my project is a full time effort that makes money and I found it worthwhile.
jyu··on PayPal Bids $500M to Acquire Crypto Startup Curv
For middle managers and above, lack of promotion for several consecutive years at a company with as many growth opportunities as Google speaks loudly.

I never worked there and was interested in her story so I dug a lot around that time and found bad reviews that have long suffered from link rot.

"But then, suddenly, her peers were promoted past her. Responsibility for the look and feel of Google’s entire suite of consumer-facing products, including the Google home page, was taken away from her. She was moved to a less important product: Google Maps. She was removed from a council of executives that met with Google’s CEO. To industry insiders, this sudden change was a demotion for Mayer." - The Unofficial Marissa Mayer Biography published in Business Insider https://www.businessinsider.com/marissa-mayer-biography-2013...

The specific criticisms from former coworkers begins around the middle of that long article.

jyu··on PayPal Bids $500M to Acquire Crypto Startup Curv
Remember that there are people behind these decisions and they are largely rational actors. Someone at PayPal is getting a big promotion and bonus from pushing this deal. If crypto goes nowhere and they shut down this project, then it can be rationalized as "getting in too early" or some other "unforeseen externality" that happened, totally out of their control. But the promotion and risk taking executive will have solidified his/her position with headcount and other markers of success.

There are always things we don't know going on behind the scenes for these types of moves.

Remember when Marissa Mayer was poached from Google to run Yahoo, and the first big move she made in a series of bungles included buying Tumblr for $1.1bn. Then she termination the option for employees to wfh. Then was later revealed that she had consecutive bad performance reviews at Google and was not going to get further promotions there before she jumped ship.

Edit: I'm just bringing up Marissa Mayer as an example and maybe misremembering the specifics since this was 8 years ago at this point. There are plenty of other examples of executives doing weird stuff that seem nonsensical from the outside. Jamie Dimond proclaiming bitcoin is a fraud while consecutively JPM buys a hefty investment in bitcoin. Or Bill Ackmann crying on CNBC while financially positioned for the exact opposite.
