Implications of this?
Thank you. Many want their cake and to eat it too.
I credit any of my "success" to the struggles I had as a child. Our world isn't perfect, and some of us experience different & harsher aspects of its flaws. I think the earlier some experience these flaws, the more they learn to adapt and realize truths of human nature. We learn that many things aren't going to be handed to us and to get what we want we will have to work a bit harder, or struggle a bit more (In the military we called this "Embrace the Suck").

We learn that our families aren't the same we see on our favorite TV shows. It hurts & its sad for young children to experience a struggle, but I think they can ultimately strengthen them -- unless the difficulties are so severe, or misguiding, that they lead children down the wrong path of life (i.e. severe psychology disorders, crime).

Again though, the world/nature is a tough place, and its nice to want to enforce being easier on and conceal realities from children, but I think there is something of value in experiencing "realness"/struggle -- a simple & less-harsh example is the losing team getting no trophy.

Ask HN: Are AWS certs getting out of hand?

Personally, I feel as though they are getting out of hand. A guy in my org literally has 5 certs, and does very minimal AWS work (basic web product). I have no certs and am building out cloud native apps in AWS doing things like batch processing millions of customer data. I'm not knocking being able to learn and enhance your skillset and marketability... I just think something is fundamentally...

Wouldnt the approach for security updates be to replace the container?

I hate the Cracking the Coding Interview/Leetcode style... studying for these type of interviews is annoying. Trying to find a good video on youtube, where they aren't just naively coding up the bruteForce->optimal possible solutions, especially is irritating. It is literally a landscape of college kids with thousands of viewers who treat these interviews like a standardized test (SAT, GMAT). Even the author of the book produces videos with very little insight or meaningful content.

"Find all the subsets in a set that add up to sum" -- "Okay for this we will use the sliding window technique and here is how it is done" -- WTF is this. I get that they want to see problem-solving skills, but this is on a different level requiring the interviewee to have studied and knowledge of the technique, otherwise we are basically trying to develop efficient algorithms from scratch and in little time. --This makes sense for college interviewees who have only studied the past 4 years, but for a professional with experience, why is this adequate??

Does algorithmic programming matter?-- still yes. But the way it is interviewed is absurd and inadequate. I had a production service centered around the stable-roommate-problem. It took me a week or two (mostly research) to develop something out and fit it into our codebase. It then took 1-3 more weeks to actually make it work for us and cover edge cases (i.e. Irving's algo quits after instability -- this isnt an option in the real-world). I read much material on the subject, other's code, had many deep-thinking sessions where I was mostly in my head, wrote unreadable scratch on paper, collab-whiteboarded (sometimes arguing), tested&failed PoCs, and had many breaks in-between it all. How successful was that project?--very, did I need to know and study techniques with lacking/meaningless basis to do it--no.

this is essential, love the analogy here: https://youtu.be/NUXpz0Dni50?t=14m13s
"Self-driving cars are here" - Not criticizing, but I thought they were already "here"?

This is just a new industry competitor, correct? or am I missing something?

OP of the comment here... Actually, I had a production service centered around the stable-roommate-problem. It took me a week or two to develop something out and fit it into our codebase.

The success resulted from deep research and much trial & error. It was no magical "algorithmic skillset" that they expect in those type of interviews (I wonder if those are even a good filter for actual production algos).

> That was a second red-flag for me - I've always worked extremely hard to establish a staging environment which reliably reproduces the production environment, so that great confidence could be had that if the released code passed the unit tests, system tests and some final manual tests in the staging environment, that it would be very unlikely that serious/obvious issues would only happen in production

I don't get why this is a red-flag though. Unless everywhere I've worked is highly flawed. Unforeseen production issues are a given, no? Like how do you actually mimic your IaaS?

There was another reply that is now gone that stated something similar where the founders would effectively limit their profit gains and declare some statement that their work was done for the people rather than profit...

I’m not trying to bring about a formal argument here and I may be way off, But IMO these type of quotes are borderline reflective of Marxism or wording that belong in Mein Kampf.

How can a business effectively make money, and scale, running on decentralized infrastructure (blockchain) though? How is it not more cost effective/business-wise to run in a centralized cloud environment? Seriously what are the business & profit models for these companies? (beyond crypto and ICOs).

Re:Hello: A new social network founded by Orkut's creator on Thursday April 12, 2018 @10:42AM (#16821409)
Exactly.

Everyone thinks that the main competitor for building communities is Facebook.com. But fbook.com does not build communities, they digitize existing ones.

So all these new apps come out with "better facebooks" not realizing (or accepting) that they already exist as Twitter, Reddit, and Instagram. These existing platforms are very good at true connection and community building.

How does "Hello" fit into that?

Re:Productivity on Wednesday April 11, 2018 @10:14AM (#16811262)
As someone with a vigorous evening workout, who awakes at 5:45am, and codes most of the day... skipping breakfast is not optimal. The frustration and anxiety caused from morning hunger is very anti-productive for me. My only eating restriction is that I very rarely eat past 8pm.

I can possibly see this being different if I didn't have a static position/desk and my mornings were consumed with meetings or high activity.

Ask HN: How are you using React Native in your production app?

It's now 2018. Most hype and notable examples I saw with RN were around 2016 (https://facebook.github.io/react-native/showcase.html).What is the state of React Native today? How are you using it successfully, and at what scale? Any large applications that have fully implemented it?My success isn't beyond fast proofs-of-concepts or simple ux applications. Success for me is defined as a system...

My major questions have always been: where is the business value in blockchain applications? what can a blockchain app do that can't be done by non-blockchain (beyond decentralization - bc I don't think this produces much business value)?
