nbarbettini··on Incident Report: Railway Blocked by Google Cloud (Resolved)
I became so conditioned to waiting hours(!) for DNS propagation that I'm always pleasantly surprised when it takes <5 min these days.

nbarbettini··on Heroku Login and Deployment Down
Now updated to say the entire Platform API is unavailable. https://status.heroku.com/incidents/2558

Edit: Maybe back?

nbarbettini··on Is Heroku’s DNS down again?
Now posted as an issue on status.heroku: https://status.heroku.com/incidents/2454
nbarbettini··on Issues with upstream DNS provider
Do you have a CNAME record pointing to a herokudns.com domain? Replace it with an A record that points to the IP instead. You can find the IP by going to https://securitytrails.com/domain/<something-1234.herokudns....

nbarbettini··on A Planetary Scientist: 'I Do Not Want to Live on Mars'
I think you have that backwards? Taking off from Mars is significantly easier than earth because of lower gravity and a less-dense atmosphere.

nbarbettini··on The Little ASP.NET Core Book
Thanks for the feedback! I don't have anything in the works right now, but will definitely consider it.
nbarbettini··on The Little ASP.NET Core Book
I have fond memories of learning VB3 from Teach Yourself Visual Basic in 21 Days, which had to be 500+ pages. It turns out it's tough to have a good introduction to a topic without going really long.
nbarbettini··on The Little ASP.NET Core Book
Very good points, thanks. I struggled with this myself as I was trying to plan out the structure of the book. I ultimately went with the "path of least resistance" (ASP.NET Core MVC ships with Bootstrap, jQuery, etc) but I agree that it could be better in future versions. :)
nbarbettini··on The Little ASP.NET Core Book
Thanks for filing the issues. And thanks for reading!

That StackOverflow runs on .NET is one of my favorite little-known facts.
nbarbettini··on The Little ASP.NET Core Book
Thanks for reading it!
nbarbettini··on The Little ASP.NET Core Book
I think it's a great time to jump into .NET Core if you've been on the sidelines. There was a lot of version pain early on, but it's way better now. Being able to write C# code on my Windows box that runs natively on my MacBook Pro feels awesome.

LINQ and the async/await pattern are my two all-time favorite things about C#.

Thanks man!
nbarbettini··on Ubershaders: A Ridiculous Solution to an Impossible Problem
SpaceX spending almost a decade developing, testing, and then deploying rockets that can land and then be reused is a good example.
nbarbettini··on Elon Musk Publishes Plans for Colonizing Mars
FYI - this is a PDF version of Musk's presentation at IAC in 2016.
nbarbettini··on Climeworks carbon dioxide capture device
We ultimately need to do both: burn less fossil fuels, and capture or sequester CO2 from the atmosphere faster than the planet does naturally. Otherwise, what we keep adding will stay around for a long time.
nbarbettini··on Backblaze B2 Drops Download Pricing by 60%
No feedback from me at the moment, other than to say that what y'all are doing with B2 is awesome. It's great to see more competition in this space, and I love the open-source ethos you've cultivated at Backblaze.
nbarbettini··on Netflix expected to spend over $6B on original and acquired programming in 2017
Master of None didn't do it for me, but I loved Stranger Things.

This is a great example of how Netflix's model works well for "long tail" content. They can produce and keep shows around that have a different or smaller audience than traditional networks can.

nbarbettini··on Former Tesla executives plan to build $4bn Nordic battery plant
Here's a different article on the same topic: https://electrek.co/2017/03/07/former-tesla-executives-gigaf...
nbarbettini··on Just how smart is an octopus?
In habitats untouched by humans, duh! Oh, wait...
nbarbettini··on Can jet engines clean up Delhi's air?
In some cases, I believe so. But a solar plant is only useful for half the day (at best).
nbarbettini··on SpaceX FCC Application for over 4000 Internet Satellites
Yes. They are going for a very different model compared to "traditional" comsats. Instead of launching very heavy, very expensive birds that need to last for 10-20 years (to justify the huge development and launch costs), they want to launch cheap and light satellites that can be replaced much more quickly.

As someone stated above, this all hinges on first stage reuse proving to be viable. If a customer buys a flight and they recover and reuse the booster, it's almost a "free" flight for them.

nbarbettini··on SpaceX FCC Application for over 4000 Internet Satellites
Lots of folks outside the cities in America too. I've heard estimates between 10-30 million.
nbarbettini··on Tesla reports first quarterly profit in more than three years
They weren't scaling back their production before. They've just been aggressively expanding the plant - they built an entire new production line for Model X (IIRC), and have been adding a lot of automation. Not all quarters have been new records, but this one is.
nbarbettini··on Introduction of C4 traits into rice to increase photosynthetic efficiency
Golden Rice isn't a failure, it just hasn't yet been deployed at a large scale. The folks working on it have been making a lot of progress, but it's been slow. (See https://en.wikipedia.org/wiki/Golden_rice#Golden_Rice_2)

Sadly, part of the reason why it's been delayed is due to fearmongering by groups like Greenpeace who are ideologically opposed to genetic engineering.

nbarbettini··on How Did GM Create Tesla’s Dream Car First?
Tesla have stated that they are open to other manufacturers using the Superchargers, so I think they'd at least entertain it. Who knows what the price negotiations would be like, though.
