charlesju··on Decluttering low-Earth orbit: It's time to tidy up space
That makes a big assumption we can't remove the junk before the density is high enough
charlesju··on The Presence of One’s Own Smartphone Reduces Available Cognitive Capacity (2017)
One trick I've been doing recently is I've reduced my cell phone internet plan to a monthly cap with rollover. And then I only turn on my cell internet when I really need it for something. This has changed my default behavior pattern outside to disconnect from the internet, and that has let me feel a lot more present in whatever I'm doing.
charlesju··on Uber and Lyft competitors ready if service is suspended in California
Wouldn't something like Ride Austin also face the same problems as Uber, which is to say, they need to hire every driver as an employee which they do not at this time
charlesju··on Ask HN: Why is Reddit on mobile so obsessed with making me use their app?

charlesju··on 27-inch iMac gets a major update
I primary drive the latest version and its my favorite mac to date (and I have the pro + imac + ipads + iphones). I have found that if you have a little bit of patience for loading, everything works just fine and the form factor beats everything for real work on the go.

If they are really creating an ARM macbook, this will be a great product and this chassis is definitely the right one to start with.

charlesju··on Google announces Pixel 5, Pixel 4A 5G, and Pixel 4A
One use of 5g would be better streaming upload speed, that can open up a lot of interesting use cases.

Another use case is streaming + AR, I can see that becoming crazy bandwidth intensive. I think there can be some cool games if we can get high mobile bandwidth and a cleaner AR (ie. Apple glasses) experience medium.

I also think if you're asking from the perspective of why would the 4a but $350 but 4a-5g be $500, then I'd guess that the 4a-5g is going to come with more than just 5g capabilities.

charlesju··on Quibi reportedly lost 90 percent of early users after their free trials expired
Another point. Especially with these content based services, it's all about the next piece of content you can provide.

For example, if Dave Chapelle signed an exclusive deal with Quibi, then all of a sudden those 92% that didn't want to come back will come back in droves.

Quibi isn't a lost cause, they set up the infrastructure and are just getting started on releasing content. Everything depends on if they can find their must-see-tv.

charlesju··on Cirque Du Soleil Files for Bankruptcy Protection
They're probably not closing, just bankruptcy to restructure their debt.
charlesju··on Facebook Novi: Wallet for Libra Digital Currencies
I think the thought process is that paper money is already controlled by world governments, so this isn't meant to be a replacement for paper money, but rather just an intermediary so the transfer of money can be done more easily and cheaper.

I think another point is that if you want a truly decentralized, no government involved, cryptocurrency, those still exist, go buy and use some bitcoin.

charlesju··on Ask HN: If you could work remote where would you live?
Another one! I love the weather here too. That's my favorite part, no need for A/C or worry about the snow. I love the fresh fruits and vegetables and going to the farmer's markets to find what's in season. We're so close to everything that you can want to do in life, that I cannot imagine a better place to grow up or live.
charlesju··on University of California Will Stop Using SAT, ACT
Empirical data shows those from upper middle class families tend to do better than those living near the poverty line. Seems pretty well documented at this point.
charlesju··on University of California Will Stop Using SAT, ACT
I think you're underestimating how much of the inequality has been baked in by Junior year of High School. 16 years of living a life where parents and teachers nurture the students for maximum growth is going to be easily reflected in any way you want to measure aptitude against someone that grew up in a rough environment.

From the article it seems like the UC are going to develop their own test, that will further divide those with resources that can study and prep for multiple tests and those that cannot.

The issues with the diversity in the UC system are rooted in a much deeper level of inequality in society that probably cannot be fixed with these band aids.

charlesju··on SF vs. Uber Eats: Service stops food delivery to Treasure Island citing fee cap
It's an island between SF and Oakland. Some people live there, probably in the few thousand I'd imagine. Very few businesses on the island.
charlesju··on Stripe raises $600M at nearly $36B valuation
Congratulations. We've recently decided to go with Paypal Pro for better rates on micropayments. Do you guys plan to have a similar program soon?
charlesju··on California’s Roadmap to Modify the Stay-at-Home Order [pdf]
The reason why your solution is not good is because it pigeon holes the government into expectations. The government doesn't have a crystal ball as to how this all plays out, they need to have the flexibility to change how they want to respond to each situation without having to defend an ultimatum.

For example, even in your own example here are several situations you didn't account:

-- The availability of tests for the public at large

-- Whether we're doing temperature checks everywhere

-- Whether we're requiring people to download a contact tracing app

-- How much capacity we have in the hospital system even though cases are going down

-- If we can find a drug that helps shorten the time people spend in a hospital

-- If we find new information like masks don't help or they greatly help

-- We run out of swabs but cases are low

There are a lot of factors that has to go into how the government changes the rules and while it might make it easier for the public to be at ease when the rules are hard, it also makes it a lot harder to adjust the rules.

I think being upset at the government is your right, but I also think you should channel your energy into something more productive and thank that at least in California we acted a lot faster than other areas of the country.

I think Governor Cuomo said something very interesting the other day, to paraphrase, when he was asked whether he should've started stay at home earlier and if that would've saved lives. Of course it would have, but the interviewer is not taking into account compliance and public sentiment. Likewise, for you, I think you're viewing this problem from a very individualistic point of view to get strict rules on what happens when, but you're not accounting for the edge cases where the government needs a backdoor to change the rules with new information and to play it close to public sentiment.

charlesju··on Apple and Google partner on Covid-19 contact tracing technology
This definitely isn't "private". It's just obfuscated.
charlesju··on Amazon begins temperature checks and will provide surgical masks at warehouses
1. Everyone should wear surgical masks

2. Temperature checks everywhere

3. Testing needs to be ubiquitous and fast

4. Backtrace every outbreak and quarantine everyone that was in contact

charlesju··on Ask HN: Best sleep trackers?
The Fitbit looks pretty close. I don't think it's perfect, but it's directionally correct.

I feel like for a lot of self improvement frameworks it's about direction not accuracy. Like for example, body fat % machines vary greatly, but surely being closer to the 10-20% range is better than 30-40% range regardless of the method you use. Probably the same can be said for sleep.

charlesju··on Waffle House closes 365 locations across the U.S.
Waffle House is so good. I was on a road trip between New Orleans and Atlanta and stopped at a Waffle House in the middle of Alabama. Biggest surprise in terms of expectations and food quality. It's like the In-n-out of breakfast food.
charlesju··on MIT to no longer consider SAT subject tests in admissions decisions
I took tests in the 1600 era. I came from one of the best public high schools in California. I would say 80%+ of the high school had SAT prep, every single one of the people I talked to at school had SAT prep.

If you're not including self study, then maybe? But with prep and self study, everyone I knew was able to get at least a 100 point increase, I think I got a 300 point increase. Basically aced the math section through practice and study (missed 1 question).

charlesju··on Elliott Management buys stake in Twitter and seeks to oust Jack Dorsey
Balance is a false paradigm, not all ideas are valid, ie. just because some people believe the earth are flat doesn't mean that in school we have to teach the earth is both flat and round. (a more 50/50 idea would be evolution or carbon dating)

I would also say Jack Dorsey has been pretty fair about the platform. I don't think the left feel like Twitter is exceptionally more open to them.

charlesju··on HQ Trivia shuts down after acquisition falls through
Words with Friends is not dead I think: https://apps.apple.com/us/app/words-with-friends-2-word-game...
charlesju··on My productivity app for the past 12 years has been a single .txt file
This is what I do too, but I have it as a general list of things I want to get done like

[] Mon - task 1

[] Mon - task 2

[] Tue - task 3

[] Tue - task 4

This way I don't hard time lock the tasks and just do them until they're done

charlesju··on Scaling to 100k Users
These posts are great and there is always great information in them. But to nitpick, it would be a lot easier to digest on face value if you lead with concurrency rather than raw total users as that's the true gauge of how your server infrastructure looks like.
charlesju··on Building all of our new mobile apps using React Native
It's open source. If you don't like the direction, fork it and do something new with the project.
charlesju··on Layoffs hit Quora
I think there is a symbiotic relationship here. Google still needs to feed enough traffic into their main training sets so it can keep training. If these training sets were to fully die (or become stale) then the Google NLP would be equally useless. So Google has an inherent desire to prop up Quora, if anything.

Anecdotally, Quora has taken a top spot in SEO alongside Stackoverflow for a lot of my searches (and Reddit). I think that over time this will improve actually and I don't think this layoff is because they are doing poorly, rather the opposite, I predict they're doing well enough to go IPO soon and need to clean house.

charlesju··on The Yang Gang and Its Bots
I understand that perspective, but I hope you can see that unlike a religion, politics, especially in USA is through people. People need to push a specific candidate because they represent a vision for yourself and the people you love.

One key thought experiment I like to do is to project out a behavior pattern for all people and then asking whether that would be a positive or negative for yourself and society. If everyone were to campaign and push for the ideas they care about, I do believe that would result in a more informed and better society. Through the marketplace of ideas, we can fight through the differences and hopefully create better policy and have better leaders execute on our future.

I think for a lot of people, taking action to affect change for the community/society you live in is very natural. On a small scale that can be something like running for class president or joining your HOA. At a larger scale, politics is where change happens.

If you believe in a set of principles, it is sometimes worth your personal time, effort, and money to affect change. Hopefully you can see that from their perspective they are about their own future and this is the most effective way to impact that prospective future.

charlesju··on The Yang Gang and Its Bots
I'm curious why you think it's weird for a group of people to believe passionately about a candidate?
charlesju··on Sam Altman and Andrew Yang talk UBI
I completely understand where you're coming from, but perhaps you're looking at causation vs correlation. For example, there are many places in the world without a welfare state going through similar issues. The real question is whether that community would be better or exist at all without assistance.
charlesju··on U.S. Navy bans TikTok from government-issued mobile devices
I think it's probably more for security reasons -- ie. they can be passing a dot map of all the Navy personnel around the world and their traveling patterns to the Chinese government.
