I would presume it depends on whom you're asking. E.g. Elon's stated multiple times that he believes requirements of degrees on many of Tesla's job postings to be "absurd"[0][1]

There are Starlink software positions available at both locations.

For example, here is a web development position in Hawthorne: https://boards.greenhouse.io/spacex/jobs/4682610002?gh_jid=4...

And a network position in Redmond: https://boards.greenhouse.io/spacex/jobs/4770694002?gh_jid=4...

mulcaheyon Keycloak: Open-source identity and access management

It can be easier to extend & customize[0] though.

I went with IdentityServer4 on a recent project over Keycloak and Gluu[1] for that reason and because it was in the same stack as the rest of our ecosystem.

mulcaheyon Robinhood Is Down Again?

> The outage was not caused by a failure to code for the leap year. We had instability in a part of our infrastructure that allows our systems to communicate with each other.

mulcaheyon Tesla Cybertruck

Doubt it. They have no experience with volume production. (Unless they basically outsource production to Ford.)

mulcaheyon SpaceX launches another 60 Starlink satellites while setting two reuse records

He means 4th reuse of _the same booster_. Not the 4th reuse of any and all Falcon 9s (if that's what you were getting at).

mulcaheyon Tesla Q3 Financial Results

They can significantly grow with declining market share if the market for electric cars itself grows significantly. That market is currently < 1% of all cars sold.

Personally, I am sticking with the phone, and I think that’s true for most people.

mulcaheyon Tesla Software Version 10.0

Around July when they hired one Adam Koszary

https://twitter.com/AdamKoszary/status/1130837644827660289?s...

He apparently got hired because Elon likes his "absolute unit" sheep meme.

Their twitter has been a lot more whimsical since. For example:

mulcaheyon Patrick Winston of MIT CSAIL has died

He does have wonderful lectures on MIT OCW

I find his presentation style is not only clear, but relaxing. It's like a friendly sermon or something.

mulcaheyon Starlink – SpaceX’s broadband internet system

What I mean is you don’t have to point a dish within arcseconds to get a connection. You just have to make sure it’s facing upwards. Per the Starlink Wikipedia page:

> Instead, it will be linked to flat user terminals the size of a pizza box, which will have phased array antennas and track the satellites. The terminals can be mounted anywhere, as long as they can see the sky

mulcaheyon Starlink – SpaceX’s broadband internet system

It’s a “user terminal” about the size of a pizza that can be mounted in a roof. Since it’s a phased array the direction doesn’t matter (unlike a traditional dish for a geostationary satellite). Once they are producing them in volume they should be pretty cheap.

mulcaheyon SpaceX first stage malfunctions during landing

https://twitter.com/elonmusk/status/1070386062164283392?s=21

Elon: “Grid fin hydraulic pump stalled, so Falcon landed just out to sea. Appears to be undamaged & is transmitting data. Recovery ship dispatched.”

mulcaheyon Poaching Tesla

Once cars are shared and autonomous they're going to be like riding a private bus, plane or train (or an Uber without a driver). You'll be staring at your phone/laptop/iPad for the whole ride and will not be personalizing anything but the sound playing over the speakers.

An Apple Care would be as if Apple wanted to get into the house market. HomeKit+devices, Apple TV, HomePod etc. are analogous to what Apple could achieve in the car space. I can't see them releasing anything better than a fully autonomous Tesla that allows you to AirPlay to the center screen.

It almost saddens me to see them poaching talent from Tesla when Tesla has so much momentum right now. I don't see Apple achieving anything Tesla won't in the long term. Instead, they're just going to delay how long it takes Tesla to get there.

mulcaheyon What Scientific Term or Concept Ought to be More Widely Known?

mulcaheyon OpenAI Universe

With this platform (and Gym) it seems like a large part of their strategy for "democratizing AI" is to grow the amateur research community. By making it easier for an individual to play around and conduct experiments, they are hoping enable progress to emerge from anywhere instead of just from wealthy companies and elite universities.

It is also a great way to be able to track and organize what is being created rather than having to sort through amateur projects scattered across the web or research publications that often lack accompanying code.

Edit:

Some key ways they're making it easier for amateurs:

* Starting point for problems to solve

* Way to get noticed (instead of needing a university/company brand)

* Technological infrastructure for building and testing. The diversity of tools they brought together to build this platform is very impressive.

mulcaheyon Senate Hearing on “The Dawn of Artificial Intelligence”

Somewhat surprised that Ted Cruz is heading this up considering his record for trust in science: http://www.npr.org/2015/12/09/459026242/scientific-evidence-...

Also, this site design is certainly above par for a .gov, I wonder who they contracted for it.

mulcaheyon Apple Is Said to Be Rethinking Strategy on Self-Driving Cars

Agree.

The "skill level" of an autonomous vehicle is continuous, not binary. I could totally see people buying a car based on how trustworthy it is (crash statistics).

Perhaps there will be some legally standard terms or discrete statistical thresholds makers will have to meet in order to legally claim certain levels of autonomy.
