davidiach··on Coinbase Announces Q1 2021 Results and Full Year 2021 Outlook
"Total Revenue of approximately $1.8 billion Net Income of approximately $730 million to $800 million"

These are insane profit margins.

davidiach··on iPhone 12 and iPhone 12 Pro
I remember the days when people were saying LiDAR will never be cheap enough for regular cars.

Now it's on smartphones.

davidiach··on Italy is extending its coronavirus quarantine measures to the entire country
Thanks for the correction, I didn't actually do the math for that, just remembered something I've read a while back, but the numbers where different 20% vs 21%.

Apparently I don't understand exponential growth either cause I assumed a 5% difference scales linearly (as in the difference between 20% vs 21% growth rates for a given period should be the same as between 2% and 2.1%).

Silly me.

davidiach··on Italy is extending its coronavirus quarantine measures to the entire country
And even fewer realize that a 2.1% growth rate is itself exponentially faster than a 2% growth rate.

If something grows by 2% per day, vs 2.1% per day, after a year the second one is >20x bigger.

davidiach··on Elon Musk’s plan to build one Starship a week and settle Mars
This 100%.

But you don't need to go to Siberia for Earth to be extremely difficult to survive in. Wherever you are, if you lack technology your chance of surviving is very low. Without clothing, housing, fire, tools it's very, very hard to survive anywhere on Earth.

The only reason life is so safe and pleasant right now on this planet is because we changed our environment to make it so.

If we were to survive on Mars, we would have to do the same. The advantage with Mars is that we wouldn't have to start from scratch.

davidiach··on Nvidia GeForce RTX 3080, RTX 3070 Leaked Specs: Up to 20GB GDDR6 RAM
GeForce GTX 1080 Ti works fine with a 4k display.
davidiach··on Lambda School is SV big bet on reinventing education but students say is a cult
At least they don't have to pay for it if they can't find a job.
davidiach··on United Kingdom Budget Visualization
Nice visualization.
davidiach··on WeWork’s 17th employee: I was not offered options
I would gladly accept lower pay at a startup than working at a megacorp. In my view, the fact the megacorps offer better job security and still have to pay a premium for employees, just show that the jobs aren't that attractive/enjoyable etc.
davidiach··on Marriage Costs in China Are Out of Control
If we don't maintain the replacement rate of 2.1 children per woman, the worlds population will eventually shrink exponentially. If that doesn't scare you, I don't know what will.
davidiach··on How YC Has Changed
Why don't you start a European subsidiary? That would be a really good way to scale without compromising on quality. The need is great for something like that.
davidiach··on Stock-trading app Robinhood was rejected by 75 investors
>They haven’t “won” anything yet...a high private unicorn valuation doesn’t mean success.

We could debate what "success" means endlessly, but if you're a VC, your job is to put money in companies with low valuations that will eventually end up with high valuations.

davidiach··on Diesel cars can be banned from German cities, court rules
I live in one of those cities as well and sold my diesel car last year when the talks regarding the ban started. I now drive a petrol car. It's not that big of a difference.
davidiach··on It can all go to zero
That's like saying the price of the Mona Lisa can go to zero just because people suddenly want it less.

Things like that don't just suddenly happen for no reason.

davidiach··on Bill and Melinda Gates Are Paying Off Nigeria's $76M Debt to Japan
Interesting perspective, haven't thought of it this way before. It does still provide some benefit to the country though, they can use that money for something else instead of having to pay it back to Japan.
davidiach··on Amazon, Facebook and Google can all be beaten
Snap is not a clear case of failing. Sure, they did not displace Facebook, but the founders and investors made a lot of money and while it isn't growing as fast as it should, it is still growing every day.
davidiach··on Just own the damn robots
I think the reason people are not excited is because we are seeing stock market growth without seeing much economic growth. That's unsustainable.
davidiach··on Waymo wants Uber to pay $2.6B in damages, just for starters
What I'm also interested in is how much money do lawsuits like these cost. Both companies have large amounts of cash, so this isn't one of those cases where the one with the most money wins, but I do expect both of them to spend a lot.
davidiach··on Our Approach to Privacy
That's actually quite a sensible proposal. I wish the implement it.

I often asked myself what happens when I give an app access to my photos. Can that app upload all my photos to their servers? The same question for things like calendar, address book, health data etc.

davidiach··on Face ID is replacing Touch ID on the new iPhone X
That's just one of the ways to unlock the phone. You can use a password when traveling for eg.
davidiach··on China's Central Bank Bans ICOs
Bitcoin is a threat to the Keynesian model. That said, it still has a long way to go in order to take over fiat currency.
davidiach··on Coinbase raises $100M at a $1.6B valuation
Just imagine how much they would have raised if they've done an ICO! :)
davidiach··on Outraged about the Google diversity memo?
I think it has to do with low knowledge of statistics.

The funny thing is that all the following sentences can be true at the same time:

1. Across the whole population, fewer women than men have the biological/psychological traits needed to become software engineers.

2. Female engineers are underrepresented in Silicon Valley and face many different forms of discrimination.

3. Female engineers at Google are on average better than their male colleagues.

I'm not suggesting any of these sentences are necessarily true, just that they can be. This is not intuitive, unless you know a bit of statistics.

davidiach··on Cafeteria workers at Facebook struggle to make ends meet
The only reason $75k/yr is considered low wage has to do with the housing prices in that area.

Everyone knows the solution to that problem is to increase the supply of housing, yet little is being done.

Maybe soon enough, $100k/yr will be the new $75k$. What then?

davidiach··on Microsoft Paint to be killed off after 32 years
I still use Paint for things like shrinking the size of an image or editing screenshots. Sad to see it go.
davidiach··on The DAO, the Hack, the Soft Fork and the Hard Fork
I wish there was a way to test this hypothesis.

Some sort of A/B test where there were two versions of Ethereum, one with the fork and another one without the fork. That way we could have known for sure if forking was a good idea or not.

davidiach··on Scientists Reverse Brain Damage in Drowned Toddler?
>Concluding, the researchers say that to their knowledge, this is the first reported case of gray matter loss and white matter atrophy (types of brain damage) reversal with any therapy and that treatment with oxygen should be considered in similar cases. “Such low-risk medical treatment may have a profound effect on recovery of function in similar patients who are neurologically devastated by drowning."

I always believed that brain damage cannot be reversed. If version 1 means reversing it in toddlers, maybe version 10 will do miracles for many other people. Truly amazing and congratulations to the medical team!

davidiach··on I make $10k per month with the Amazon Affiliate Program
Is that a one person company?
davidiach··on Author of cURL denied entry to the USA
This was my experience as well back when I traveled to the US. It was quite surprising.
davidiach··on Six contenders to be Uber's new CEO
If they hire someone for image reasons, Uber is going to fail badly.
