This is hilarious. Can we get a blog on how you built it?

What are you using that isn't USB C/Bluetooth at this point? Honest question.
charlesju··on YouTube says it has ‘no obligation’ to host anyone’s video
Can't you just throw up a website and serve mp4 files? YouTube doesn't owe it to anyone to serve videos, it's just one way to consume video content online. If you want to move off platform, the technology and services are both open and widely available.
charlesju··on Nuclear energy is a vital part of solving the climate crisis
70 years is not enough time to fully flush out the potential of nuclear power. We're already on the cusp of breakthroughs with Thorium (cleaner) and Fusion (more and cleaner) power that are derivatives of the science from nuclear.

There are several countries that rely heavily on nuclear today and have done so successfully and in a way that has helped curb their greenhouse gases: France being one (https://en.wikipedia.org/wiki/Nuclear_power_in_France)

Additionally, nuclear has unlocked insane potential in the military with nuclear subs and ships. They can go a whole year without refueling and at the micro level they are very effective. (https://en.wikipedia.org/wiki/Nuclear_marine_propulsion)

So to your first rhetorical question. What lesson have you learned from Nuclear the last 70 years? What I have learned is that it's an incredibly effective and green source of energy. It's a type of power that we should invest more money into not only for green energy production, but also for the future potential derivative technology. We can solve climate change tomorrow (in the sense that next 30 years is tomorrow) if everyone made a conscious effort to adopt nuclear in all forms of energy consumption.

No one in Nuclear is saying no wind/solar/batteries, everyone in Nuclear is saying we should do everything that doesn't catastrophically harm the environment and we should invest more into a very powerful and ultimately useful technology.

Imagine a world where energy is functionally free and robots have enough AI to do most basic motor tasks, they can grow and deliver crops start to finish, run stores and shops, build houses and provide the materials necessary to do that. We're not that far from that reality and pushing the human cost to have basic living standards met down to near zero. We're also looking into nuclear as a primary fuel source for space travel, traveling to mars right now takes 9 months, that's an incredibly amount of time round trip for a human, just look up humans that went to the space station for 12 months, you need to spend about 3x that time to go to mars, that's incredibly harmful, if we had nuclear, we might be able to dramatically shorten that. (https://www.space.com/nuclear-propulsion-future-spacecraft-n...)

I know you think Nuclear is scary because sometimes things go wrong, we have to figure out a better way to deal with the waste, but in this science based community lets try to be the first to promote more science first and not let the fear of what could happen stymied the progress we all need.

charlesju··on Time to Take Down the Mona Lisa?
I think it's reasonable to create a separate room for the mona lisa and establish a digital queue system where people sign up for a specific period of time to visit the Mona Lisa. That would solve all of the author's issues and still give you all the benefits your niece gained.

Similar issues exist for major paintings across the world. Not a big problem to spend too much collective brain power on though.

charlesju··on Ask HN: How do you make sure your servers are up as a single founder?
I would say that as a one person founder, know that you cannot ever get 100% uptime and live with it. In the most simplistic sense, you need to sleep 8 hours a day, you cannot live your life constantly stressed about uptime. Just generally have internet access and sometimes your service will go down.

On the set up, try your best to solve issues and use tried and true hardware, but things go down sometimes, even big sites like Google, Facebook go down, there is no silver bullet, you can only improve on your past mistakes.

Last, try to find some remote help, on a contract basis, it's not that expensive and it can help alleviate a lot of your stress.

charlesju··on How California Became America’s Housing Market Nightmare
I would say it's especially unfair to new California residents and great for their children.

I grew up in Silicon Valley and almost everyone I grew up with have parents that live very comfortably if for nothing else than their property value skyrocketing over the last 3 decades. Everyone that bought a house in the 1980s or 90s are now millionaires a couple times over.

As children of wealthy parents, the natural benefits are going to be passed down to us, if not in the short term through day-to-day subsidies but in the long term future through generational wealth.

The real issue with Silicon Valley was the tech boom after 2004, tech companies went from being worth a couple billion to several being worth multiple hundreds of billions. That amount of wealth in a 15 year time frame is really hard for the public infrastructure to keep up with.

charlesju··on Stripe to move to South San Francisco
1. San Francisco is really nice. It's 87 degrees today at the end of October. There is good food, decent public transportation, culture, ocean, forests, etc. It doesn't snow here or get blistering hot, so productivity is very steady year round.

2. Because San Francisco is very nice (perhaps) and we have good schools around here. A lot of hires come from UCB, Stanford, UCLA, USC, and other UCs. Those account for several of the top engineering schools in the country/world.

3. Silicon Valley has hit an inflection point where we're now the best place in the world to find TOP talent in tech. It's not a great place for mid and junior level talent, but if you need top talent for an opportunity that is high growth and high per employee leverage, there is no place better in the world.

Ultimately, the main issue is that everything is too nice and worked too well so the cost of living has sky rocketed. And that is driving out everyone that isn't a top tier talent (engineering and opts). It's really sad, to be honest, I love San Francisco and Silicon Valley, and I wish we could find a way to solve the living cost issue and continue to grow as a hub for innovation.

charlesju··on The next big thing will start out looking like a toy (2010)
Scooters, Bitcoin, Tinder, Meditation Apps. Then literal toys like Fortnite, Pokemon Go.
charlesju··on My Time at Snap
There are a lot of strategic reasons to do this:

1. Internally you'll feel like you're growing still even though you aren't

2. Externally to investors same feeling

3. You will collect resumes in case you want to fire up hiring again quickly

charlesju··on My Time at Snap
It's probably because they were bleeding money at that moment and weren't hiring anyone outside super unicorn seniors, but they didn't want to update their job descriptions
charlesju··on China Grew Two Cotton Leaves on the Moon
I think the main difference at least in accordance to the movie is this wasn't activating lunar soil, it was using earth soil on the moon.
charlesju··on Water found on a potentially life-friendly alien planet
Also assuming no acceleration or deceleration time in this made up impossible scenario. In the more likely scenario where we can get to a fraction of the speed of light using current technology we do have to account for both factors in both time and space probe weight.
charlesju··on I Quit Social Media for a Year
As a side note, a hobby/hack I've found recently has really helped me decrease screen time.

I need to work a lot due to job circumstances, so I thought I could not afford screen off time.

But one thing I picked up is writing in a notebook. I realized that a lot of work, regardless of where you are on the totem, is planning ahead. Writing in a notebook for both work and personal introspection is very therapeutic and really helps me to focus and crystalize my thoughts. I've also bundled this with my work out sessions to pre-plan what I want to pontificate about. The general process has both helped decrease my screen time, increase my work productivity, and help me sleep better because I know that my frayed thoughts are on paper.

charlesju··on Apple Watch Series 5
If you need a watch that can make phone calls then the Fitbit is not a good watch choice. I personally don't like making any phone calls and if I have to, my phone is usually near by. But that's a very personal choice.
charlesju··on Apple Watch Series 5
I agree with this sentiment. But then I discovered the Fitbit has a 7 day battery life. That's a game changer.
charlesju··on The first solar road has turned out to be a disappointing failure
So you're saying space laser energy is definitively better than solar roads? I think that's a little preemptive.
charlesju··on The first solar road has turned out to be a disappointing failure
I don't understand why we can't pursue all of those options at the same time. Especially solar road vs laser energy from space.

Solar roads has the distinct advantage over covering all the roads in that it's not an eye sore and fits more seamlessly in the scenario we figure out the engineering.

charlesju··on The first solar road has turned out to be a disappointing failure
Why not both? Neither works right now, it's probably prudent to try as many interesting things as possible.
charlesju··on CutiePi – All-in-one Raspberry Pi tablet
What projects do you need a tablet and you need it unlocked?
charlesju··on CutiePi – All-in-one Raspberry Pi tablet
Can't you just install a regular android app? Why do you need to unlock it to do anything?
charlesju··on CutiePi – All-in-one Raspberry Pi tablet
Call me dull, but why don't you just build an android app and buy a Fire Tablet to power your project.

A Fire Tablet is probably on par for power and is fully integrated with a touch screen and battery, and with discounts it costs almost or cheaper than a bare Pi.

I feel like we bend over backwards to try to use the Raspberry Pi to do cool things, but a lot of these projects can be developed more easily and powered by a more consistent framework using a Fire Tablet.

charlesju··on Fewer Than Half of Google Searches Now Result in a Click
It's important to note that this is strategically incredibly important for Google because this forms the backbone of their voice AI. The better at answering questions directly, the better their voice AI becomes and that leads to a lot of future products.
charlesju··on Show HN: We track Reddit, Google trends, Twitter, etc. to find trending topics
GREAT JOB!

Launching something new is always hard and I'm happy for you.

I would look at: https://scottscheapflights.com/

They have a similar business model to your product, and I think they do a great job balancing free and paid.

Another great model for what you're doing is: https://www.instagram.com/chartrdaily/?hl=en

Personally, I think you guys are trying to upsell too early. I would hide the upsell more and focus more on converting subscribers and delivering more value up front.

charlesju··on Apple Plans to Bankroll Original Podcasts to Fend Off Rivals
Does anyone else think the Podcast app is unusable? This is what I'd do if I were Apple.

1. Fix your app for people that sub to more than 10 podcasts, I crash all the time and takes me maybe 5-10 minutes to load into the app. I had to switch to Spotify because I can't use Apple's version anymore.

2. Host podcasts for premium members. Run ads for them.

3. Create an Android and Windows app. Separate Mac app. Own this space.

charlesju··on Costa Rica has run on 100% renewable energy for 300 days
If we believe climate change is a catastrophic disaster for humans now and near future, we should do everything to protect ourselves.

There is a false dichotomy of renewables vs nuclear. Pursuing these options are not mutually exclusive. Only in so far that we want to devote limited resources to the problem.

The real solution is that we should pursue both. Nuclear so we have a back stop to the problem. Renewables so that we have hope for the best case clean and safe energy future.

It is foolish to believe the projections on renewables will absolutely happen. There are a lot of problems that can happen with technology at scale. Nuclear is a surefire bet, with risks being nuclear meltdowns and improper waste management.
