ertand··on Textbook errors in binary searching (1988)
That was my favorite chapter in Programming Pearls.
ertand··on Ask HN: Favorite nonfiction books of 2018?
It's an old book but I really enjoyed Liar's Poker (1989) by Michael Lewis.
ertand··on Doctors warn of alarming C-section 'epidemic'
Misoprostol is also a cervical ripening agent comparable to cervidil.
ertand··on Doctors warn of alarming C-section 'epidemic'
Makes sense. As mentioned in the comments, there are different ways of inducing labor. I was referring to usage of pitocin or similar too early in the process, instead of gradually inducing the labor with other medications. We had success with just misoprostol during our labor, but the process was quite long.
ertand··on Doctors warn of alarming C-section 'epidemic'
Sorry for not being clear, I was specifically talking about pitocin level induction.
ertand··on Doctors warn of alarming C-section 'epidemic'
I wonder what its correlation with induction is. Artificially inducing labor does not tend to give the body enough time to adjust and progress.
ertand··on Slow leak detected aboard Space Station
I wonder what the procedure to locate the leak was.
ertand··on The Scooter Economy
I was hoping to get a more in-depth analysis of the 2-sided network effects of the scooter space. I'm having a hard time understanding the defensibility of these companies against each other. Habit doesn't seem to be enough to win the market. Exclusive contracts or leveraging regulations could be options but they don't feel strong enough either.

If it's not a winner takes all market and multiple players can coexist at the same time, then I don't understand the investment decision from the VC firms to value them so high so early. It feels like Uber/Lyft can easily get into this market and provide a better experience overall.

ertand··on Getting Started in Natural Language Processing
You could jointly train a NN to parse the sentence and tackle the NLP task you have at the same time, or instead of just using the tokens you could use a parser to add more features too.

edit: clarification

ertand··on Unfortunately, the Electric Scooters Are Fantastic
Uber and Lyft are different than scooter services because they leverage the network affects by the availability of drivers and wait times. Scooters could race to cover more districts and provide high availability but this can easily be commoditized. Also, cities have limits on the number of total deployed scooters within a city.

If the scooter companies can get bought by Uber or Lyft, these ride sharing services could also take on the responsibility of distributing these scooters across the city and make them highly available. That would compliment their ride sharing service tho.

ertand··on Unfortunately, the Electric Scooters Are Fantastic
I seriously don't understand how one scooter company could differentiate itself from others significantly from business perspective.
ertand··on Simplify Login with Application Load Balancer Built-In Authentication
I think the main difference between the two is, IAP aims to replace VPN requirements for Enterprises. It only integrates with Google accounts and it seems to go hand in hand with GSuite. So they are more B2B oriented. We hide our staging servers behind IAP for instance.

Amazon's solution seems to integrate with a few other identity providers and gives the developers the tools to do authorization after authentication is done. It seems to position this more like a B2B2C. Although it feels like it already subsumes Google's IAP by doing so.

This is my understanding by reading the article on Amazon, I haven't actually used it.

ertand··on Show HN: ThePDFApi, a Chrome Based PDF Generation API Hosted on AWS
You might also want to take a look at https://github.com/GoogleChrome/puppeteer/issues/557#issueco...
ertand··on Show HN: ThePDFApi, a Chrome Based PDF Generation API Hosted on AWS
I don't know much about the complexities of this task so excuse my question if it's too obvious.

How is it different/better than using puppeteer? If it's better, maybe SxS comparisons of generated pdfs could be a good selling point.

ertand··on Google is rebranding storage plans as “Google One”
Google Duplex was a cool demo but those intents were quite well defined. There is a handful of form slots they are aiming to fill where they can enumerate all the entry points to a conversation as well as misinterpretations. I do agree that this is the direction we are going, however since Google Expert is a broad term tackling a much bigger search space, I'd expect it to work differently.
ertand··on Google is rebranding storage plans as “Google One”
I wonder what they mean by Google experts. Will there be an actual human being or some hybrid solution at the end of the line? Not that it matters to me as long as it's efficient.
ertand··on Show HN: Watch Stanford CS Lectures Together
Good job! Is there a way to engage with other students after the class? Would be nice to ask follow up questions.
ertand··on Launch HN: CoinTracker (YC W18) – Cryptocurrency portfolio and tax manager
I think this is the best tracker I've seen. Congratulations on the launch!

Will the tax manager be the main part of your business or are you planning to monetize on different set of features? Will cryptocurrency tracking always be free?

How do you aggregate the cryptocurrency prices across exchanges? Do you only calculate it based on the exchanges you support?

ertand··on Show HN: An extension to turn your LinkedIn into a resume
Yup, as solotronics said.

On Chrome extensions, minor bugs (or minor bugs in the libraries you depend on) might end up having far worse consequences. Read/write access to only linkedin.com can still leak a decent amount of unwanted information in case there's an exploit.

ertand··on Show HN: An extension to turn your LinkedIn into a resume
Looks great. I love the styling.

As a general feedback: I'm a bit cautious about using third party Chrome extensions. I'm more OK with giving auth to my LinkedIn account. Maybe a server side option with headless chrome would be a good addition.

ertand··on AWS Lambda Releases Go Support
C++ is definitely in top 3, along with Java.
ertand··on One of the Biggest Crypto Exchanges Goes Dark and Users Are Getting Nervous
Yea, database migration is my first guess as well. Any code change would have been reverted quickly otherwise. Their blog post about the incident is not clear enough. https://blog.kraken.com/post/1449/kraken-returns-with-free-t...

Either way, it looks bad from both engineering and product perspective.

ertand··on Show HN: Monthly subscription airline with SFO-LAX flights starting at $78
That's a major win against traditional airlines if you could transfer your flights to someone else.

I think you wanted to make sure the best price option is in the middle but it threw me off a bit. Consider putting them left to right, from worst deal to best? Also, consider using numbers instead of words: 2 flights, 4 flights, 6 flights?

ertand··on Learn to Code Ethereum DApps by Building Your Own Game
I think the main motivation for a developer who believes that ETH will solve the scalability challenges at some point is to master these technologies early on. I have lots of doubts about DApps but I can see why it's good to learn them now.
ertand··on Facebook’s Virtual Assistant M Is Dead
I agree with this. It's a matter of scope and therefore a product problem. What can be done using NLP today is not a secret and I'm sure Facebook was already aware of the shortcomings. They could have reduced to scope to a more tractable problem, but they chose to cover everything that a consumer might want.

I think there are a lot of good use cases that can be automated today.

ertand··on Open Beta of Texpad 1.8, macOS LaTeX editor with integrated realtime typesetting
Really cool project. I have some comments tho.

I don't quite understand what Connect is. Is it a cloud IDE or is it an add-on to sync your projects across existing clients on Mac or iOS. I think this wording confused me the most on the OSX client: "$9.99 + 6 month subscription* of Texpad Connect". I'd package it as: if you buy OSX client, you get 50% off from Connect for the next 6 months. Or even better, just give 3 month Connect for free with each license.

Also, I don't understand why you'd have to buy Mac and iOS licenses separately. Wouldn't it be nicer to use a single license across all of your devices?

ertand··on Is Filecoin a $257 million Ponzi scheme? [pdf]
Thanks for your clarifications. That was my guess too, I just wanted to confirm it.
ertand··on Is Filecoin a $257 million Ponzi scheme? [pdf]
I think it would be helpful if the authors disclosed whether they invested in Filecoin. I didn't really see it anywhere. Did I miss it?
