jennyyang··on A nameless hiker and the case the internet can’t crack
Here is a link to his notebook that they found on him:

jennyyang··on The Fall of Silicon Valley
I never said all billionaires are geniuses. You are not engaging in a sincere conversation.
jennyyang··on The Fall of Silicon Valley
Kalanick is a billionaire, many employees in SF are multi-millionaires, and millions of drivers around the world made a lot of money driving on the platform and continue to do so. I heard in Brazil, Uber helped 300,000 drivers alone make money during their very deep recession. I think that sounds like a genius to me.
jennyyang··on The Fall of Silicon Valley
The genius of Travis Kalanick is twofold:

1) Going global as quickly as possible. He aggressively moved into a lot of countries as quickly as possible with the same formula, and for the most part it worked.

2) He created an entire industry by having the balls to lower prices to the point where it fundamentally changed transportation. Everyone ubered everywhere (before the pandemic) and I know many people who sold their cars because ubering was cheaper.

The downside was that both are extremely capital intensive, which showed in how much money they raised. But I would say both techniques are extremely innovative and what most startups these days are trying to strive for.

jennyyang··on Evolving Reddit’s Workforce
It could happen, and you will need to adapt to it. Change happens all the time, and only those that resist change will suffer from it, while those that bend with it will benefit from it.

That said, I really don't think remote work will be permanent. Once the Pandemic is over, people will relish going into the office. Most people WANT to work at an office, regardless of the commute. It runs between 60-75% of all people want to work from an office, and it is more efficient.

jennyyang··on Over 80% of Covid-19 patients in a hospital study have Vitamin D deficiency
Paper suggesting vitamin D might protect against COVID-19 earns an expression of concern

https://retractionwatch.com/2020/10/26/paper-suggesting-vita...

This isn't a home run yet, even though I would like to believe that Vitamin D has protective nature.

jennyyang··on My platonic ideal for how engineering hiring should work
A company's hiring practice should reflect the type of engineer they want to hire. If they want to hire engineers that can start contributing immediately, and they hire engineers that need mentoring, then the hiring process is broken.

If they widen their expectations, and hire people that they believe they can mentor into net contributors, then their hiring practices should reflect this.

There are many ways a company can make hiring more scientific, including A/B testing (ie. hiring people they normally wouldn't, have more data around how productive new hires are, etc) but I've never seen it over than "copy Google and we should be good."

jennyyang··on My platonic ideal for how engineering hiring should work
I guess if they can take someone they would not have hired, and then mentored them to become a net-contributor, then the hiring process is broken. You can't really test this without hiring people you wouldn't normally hire based on your hiring process.
jennyyang··on Swedish virologist says her country's strategy has failed, but nobody admits it
If 85%+ of the people are getting infected with mild or no symptoms, and those most susceptible to death are quarantined (those over 60 years old), then you have a best case scenario where the death rate is around 0.5%. What we need right now is a test to determine who that sub-10% are below the age of 60 that will get severe symptoms or worse, and isolate them as well.

We have no idea how successful a vaccine will be. If it's 50% successful, that means that people will be getting Covid-19 regardless, so it seems we might as well front load the infections now.

In addition, recently they found a new variant of SARS-CoV-2 with a mutation in the spike protein. If the spike protein mutates enough such that the vaccine no longer works, then we really have no choice but to reach herd immunity.

jennyyang··on My platonic ideal for how engineering hiring should work
The thing that companies fail to do is reconcile hiring decisions with performance reviews afterwards. They have a single hiring practice and they NEVER EVER change it, regardless of the quality of the eventual hires.

The missing feedback loop from performance review back to the hiring process means that the hiring process can't get fixed. Until companies start adding that process back in, hiring will never get better.

jennyyang··on Swedish virologist says her country's strategy has failed, but nobody admits it
The interesting thing about Sweden is that they are going through a second wave even though they basically didn't do anything to stop the virus. I'm curious what caused the drop in infections and then the subsequent second wave.

The other thing is that deaths are basically at lows. So high infections and low death rate is basically what they want, isn't it?

jennyyang··on Why does Instagram continue to store and use all of my contacts?
People in Europe need to keep hammering US companies with GDPR violations relentlessly. At some point, if a company keeps violating GDPR, do the executives become criminally responsible? If not, they should be.

I wish the US had something similar at this point.

jennyyang··on YouTube bans coronavirus vaccine misinformation
> things are going to need to be sacrificed.

What a comically cliche and stereotypical error that people keep making. 20 years ago it was the Bush and Cheney saying the same thing. Now its the liberals saying that the "poor, ignorant masses" need to be saved from themselves. For the record, I'm also a liberal, but old school liberal, not the contemporary liberal that eschews giving the same rights to those that I disagree with.

Who gets to decide what gets sacrificed? You? What happens when The Other Side gets control? The laws that protect their free speech are the exact same laws that will protect our rights when the opposition gets control.

Never, ever, ever mess with the ideals of Free Speech. No one is smart enough or uncorrupt enough to navigate that properly. The only thing that will save us as a society is completely unadulterated free speech. What we do as a society is to educate as best as we can and let the chips fall where they may. Which is hard, because we have the worst levels of education in developed countries, so we are reaping what we sowed for the last few decades. But basically it's herd immunity for information.

jennyyang··on Advice to my young self: forget side projects and focus on your job
The creator of homebrew flunked a Google interview because he couldn't invert a binary tree. Everyone at Google that he interviewed said they used homebrew and loved it, but ultimately it didn't matter. He couldn't invert a binary tree.

So side projects or even real projects that are used by millions are literally meaningless.

Study LeetCode instead to get a job and focus on your job at work.

jennyyang··on Harvard, Oxford, Stanford doctors among leaders of global anti-lockdown movement
My mom is in a memory ward. The access to visitors is extremely limited. At one point we could only visit through a window to wave hello. Now, visitors are allowed in certain areas. But it's not foolproof and I'm sure if there's an outbreak there will be a lot of casualties unfortunately.
jennyyang··on Harvard, Oxford, Stanford doctors among leaders of global anti-lockdown movement
To a large degree, this makes sense.

In the UK, 75% of deaths are people aged 75 and older. I'm not sure if its the same age profile in the US but I would think yes. Even here in the Bay Area, the death rate is about 0.5% for everyone below the age of 60. If we lock down those over 60, and let everyone else live with masks and social distancing, the infection rate may skyrocket but the hospitalization and death rates will plummet. This is basically what we are seeing globally now, where the infection rate is higher than in March but death rates are much lower. Granted, there were less tests being run so that makes things hard to compare.

Also, the bigger problem is those that need to take care of their parents who are in this age group. The infectiousness is so high that if the children get sick, the parents will definitely get sick. So this is the biggest quagmire, that entire families will become isolated to protect the parents. It's not a perfect solution but better on a percentage basis for the entire country than locking down everyone, even though the risk profiles are drastically different.

jennyyang··on Abolish the Cash Bail System
The conviction rate is very high, upwards of 85% in some states. So it's not like large swaths of completely innocent people are being held in jails. I'm okay with pre-trial incarceration as long as everyone gets treated equally.

Since they aren't, I think non-cash bail is a good idea, with strict requirements to check in with an officer, etc. If they don't meet their appointments or break the terms of their bail, I'm also okay to see them incarcerated pre-trial.

However, there needs to be some provision to make sure that they don't stay in jail longer than what their offense would have garnered. If someone is in jail pre-trial for half the median time an average punishment if they were found guilty, then the charges should be immediately dropped. This should give prosecutors more incentive to get their acts together and have a trial in a reasonable amount of time.

jennyyang··on Timekeeping in Financial Exchanges
Why on earth would they pay $300M to have a fiber cable to Chicago? It sounds like they could move all their employees from Chicago to NYC for cheaper!
jennyyang··on Doctors Group Sues California for Failing to Add Processed Meat to Cancer List
Does this include bacon etc that are nitrate and nitrate-free? I would think uncured processed meats wouldn't be the same, would it?
jennyyang··on Work on What Matters
At my previous company, I worked on high impact, very low visibility work. I was working directly with operations teams around the world in order to enable features that needed to be tweaked globally. It was vital for teams in their specific geography to work properly, but no one beyond those teams and my direct manager understood what I was doing. I enjoyed it because it was literally enabling functionality across countries around the world which was great for our customers and our company.

During that time, the team around me dissolved due to severe attrition, leaving a skeleton crew of developers and I was the last remaining developer working on this specific project. During performance review time, I was told I wasn't performing at an adequate level because the number of code reviews I performed was very low. When I pointed out that I was the only person on my team, so no one came to me for code reviews their response was that I should have sought out code to review on my own.

I quit soon after.

jennyyang··on They're deleting my channel, but they don't know why? [video]
The fact that Google/Youtube has zero support infrastructure should be evidence that they are a monopoly and engaging in monopolistic activity.

If Google/Youtube were NOT a monopoly, they would have invested significant amount of money in customer support. However, there is zero. The only reason they get away with this is because they have a monopoly. They are saving hundreds of millions in support costs by not delivering any support. Unlike more overt monopolistic actions like raising prices, etc, what they do instead of increase their profits by taking away functionality that their customers should be receiving.

The fact you can get all your work taken away because of fraud, and have no recourse is unacceptable. Yet there really is no viable alternative. I hope content creators band together and form a class action lawsuit against Google and break up their monopoly. It's disgusting.

jennyyang··on HSBC moved vast sums of dirty money after paying record laundering fine
Is this not the case of banks finding money laundering and then collecting the transactions and sending it to the authorities?
jennyyang··on Oracle Wins Bid for TikTok in U.S.
As far back as 15 years ago, Oracle had the reputation of being the company where people would come to work, close their office door, and then work on a second job or side project in peace and quiet. Oracle was/is powered by zero innovation and all enterprise sales.

I thought the idea of Microsoft buying TikTok was funny, but I couldn't think of a company more effective to dismantle TikTok than Oracle.

jennyyang··on SoftBank unmasked as ‘Nasdaq whale’ that stoked tech rally
Inside information doesn't have anything to do with market manipulation. The trader who caused the Flash Crash in 2010 was similarly prosecuted for artificially manipulating the markets. If Softbank was buying options to somehow manipulate the rest of their trades, I can't see how this isn't illegal.
jennyyang··on SoftBank unmasked as ‘Nasdaq whale’ that stoked tech rally
How is this legal? If they are buying options to force the markets to rise like this, isn't this blatant market manipulation? Or is this okay because they have a lot of money?
jennyyang··on Expert predicts a major hurricane hitting Houston would be “America’s Chernobyl”
Overall the number of hurricanes is down dramatically. 2 in Texas don't break that trend.
jennyyang··on Expert predicts a major hurricane hitting Houston would be “America’s Chernobyl”
Anyone can write any story they want in the age of the Internet. It doesn't make them right, it makes them lucky.

Look at Peter Schiff. He correctly predicted the housing meltdown, and since then he's been consistently wrong for the last 12 years.

jennyyang··on Expert predicts a major hurricane hitting Houston would be “America’s Chernobyl”
Every few years? Katrina was 15 years ago, and has been a relatively lull in hurricanes since then.
jennyyang··on Pulse oximeters give biased results for people with darker skin
Medicine is very rarely about absolutes, it's mostly about how things get better or worse. When I was in the hospital, no one looked at the absolute values of my blood work, they cared to see if it dropped based on the treatment they saw.

Also, doctors are already aware about how oximeters may be inaccurate. It doesn't mean that they still can't be useful.

jennyyang··on Why aren’t we talking more about airborne transmission?
Thank you, you're repeating things I've already stated in my first post. I suggest reading things more carefully.
