davmar··on 'Alarming' loss of insects and spiders recorded
only about half of the species of spiders spin webs. the others are hunters.
davmar··on PG&E is shutting off power in Northern California again
i mean you're probably right, it's a wild theory. but, maybe their leadership is made up of hard right conservatives that are willing to do what it takes to keep power (political, not electrical power...ha)
davmar··on PG&E is shutting off power in Northern California again
those are some interesting theories. the big secret gov't project is probably like stranger things then. they need the power to drill a hole into the upside down!
davmar··on PG&E is shutting off power in Northern California again
well, it's a conspiracy theory so it's half-baked by definition. the point would be voter suppression to affect the outcome of the election, of course.
davmar··on PG&E is shutting off power in Northern California again
i have this conspiracy theory: PG&E is normalizing power shutdowns around this time of year and on Nov 3, 2020 they'll shut off power to specific areas while people are voting for the next president.
davmar··on Amazon Employees Pledge to Walk Out as Part of Global Climate Strike
if you think that people fighting to preserve organized society on earth from the reality of climate apocalypse is "the latest moral crusade" or a "political crusade"...

you're wrong.

davmar··on India's oldest yogini: V Nanammal, 98
i've been to india twice to study yoga for months at a time, and i've done all kinds in the US. ok there are my creds.

yoga asana - the moving aspect - is only 1 of 8 branches of yoga and it has evolved significantly over time.

Even BKS Iyengar, the man who brought yoga to the West, changed his practice over time from a strong, powerful and probably sweaty style when he was younger to a slower style as he aged.

there isn't a "right way" to do yoga, but if you're looking for authenticity then follow a lineage that has ties to India. Iyengar yoga is probably the closest in the US and even those expert teachers will have different styles.

at any rate, find an instructor that gives detailed instructions. you shouldn't have to look at your neighbor to figure out what your body ought to be doing, and the point isn't for your hand to reach that one hard-to-reach place on day 1. that's why there are props because everyone's body is different.

davmar··on Data API for Amazon Aurora Serverless
came here wondering the same thing. those cold start times aren't acceptable for user-facing apps and i had to switch a serverless project from RDS in a VPC to dynamodb. even worse is that these cold start times are for each lambda, so if you've got concurrent usage then each new lambda spin up causes a cold start.

having said that, i'm actually pretty happy with dynamodb...so far.

davmar··on Curiosity rover gives Nasa a scare, needed a reset
happy to hear comcast support was able to help out on mars. just unplug it and plug it back in.
davmar··on Ask HN: What skills to acquire in 2019?
I'm not sure what you mean by this comment. How does it relate to the discussion on racial equity?
davmar··on Ask HN: What skills to acquire in 2019?
Our industry is behind when it comes to understanding race and racism. Proof: Slack's mistake this last week.

In 2019, learn about institutional racism and why we have to undo it. Take a course from the People's Institute. If you haven't learned about this in depth before, be prepared to learn a lot and have your preconceived notions challenged.

I promise you'll walk away with new perspectives and discover a whole new area you can grow and make a difference in.

i gave you my email address. what have i done? haha
davmar··on Announcing the Winners of the 2018 MIT Media Lab Disobedience Award
I disagree. I believe the most difficult engineering problem in the world is changing human behavior and decision making at scale. Not behavior in terms of "tap the screen more often", but actually changing how we treat each other, how we treat the planet, consumption and consumerism versus preservation and reuse. To that end, this is engineering, and they are on the right side of history.

Further, social activism as engineering is important. It's engineering behavior so we're more inclusive. Inclusivity is important because we need lots of perspectives on how to solve problems. The more perspectives we have, the better our solutions will be.

davmar··on Estimating the chances of something that hasn’t happened yet
(1-p)^n is one my favorite things. happy to see it get some attention.
davmar··on Tensorflow 2.0: models migration and new design
Hello. Third idiot checking in.
davmar··on Tensorflow 2.0: models migration and new design
as if it wasn't already confusing enough. should i use tensorflow hub? TF slim? keras applications that import tensorflow?

should i still use those outdates TF slim models that are for some reason kept in models/inception?

please, tensorflow team, make this stuff easier for us non-Phds.

davmar··on Making floating point math highly efficient for AI hardware
caveat: i haven't finished reading the entire FB announcement yet.

google announced something along these lines at their AI conference last september and released the video today on youtube. here's the link to the segment where their approach is discussed: https://www.youtube.com/watch?v=ot4RWfGTtOg&t=330s

davmar··on iPad Pro
i disagree in that i do see a future for macOS. steve jobs said it best - sometimes you drive a convertible, sometimes a pickup truck.

macOS may be the pickup truck. but it isn't going to go away without a fight. not unless you can make software engineering work on an iPad the same way it does on macOS today.

davmar··on Meet the startups racing to reinvent the meal
yes, factor in human nature but first understand what it is. there are 360 million vegetarians in India, for example. eating meat isn't coded in our DNA.
davmar··on Ending Bitcoin Support
your assertions about fees is exactly backwards. if there are fewer transactions, the fees go down. each block has a finite number of transactions it can include, so to get yours included you attach a fee. therefore, increased demand increases the fees and visa-versa.
davmar··on XMR mining app, built with Vue.js, D3 and CoinHive
monero is where it's at imho

davmar··on We fired our top talent. Best decision we ever made
The author has the audacity to lay 100% of the blame at the feet of his "genius". Sadly, the author will run continually into new sets of problems again and again at his company and each time find a new scapegoat. This is because 1) he cannot recognize that he is the problem and 2) attacks those who has scapegoated in public.

Until the author matures, employees would be wise to run in the opposite direction. If they don't the next article will be about one of them.

davmar··on YC’s 2016 Holiday Gift Guide
airbnb is a much, much more economical option while traveling over hotels when booking in advance for a couple. it was even cheaper than a private room in a hostels in berlin.

source: traveling for 1.5 years using airbnb, hotels, hostels.

davmar··on YC Changes
ok.
davmar··on Alan Kay on AI, Apple and Future
He sounds like a grumpy old man mixed with a bit of hipster. If you can dismiss the mobile revolution as selling "sugar water to children" you're wearing blindfolds. Look at adoption rates of these devices all around the world - it's unmatched in human history. Look how they've given access to healthcare and finance in poor countries.

And he calls it "sugar water". Baffling.

davmar··on Alan Kay on AI, Apple and Future
Depends on your definition of "significant breakthrough". Technical breakthroughs are what Kay values, and that's OK. But to suggest they're the only kind of breakthroughs is myopic. Startups can, in their best incarnations, change human behavior and the way we interact with our world.
