Contact jared@scoot.co for details. Come join us and be a part of the electric vehicle revolution!

jluxenberg··on Apple Plans to Use Its Own Chips in Macs from 2020, Replacing Intel
iOS apps do not run via emulation on macOS; they are compiled for x86_64 and run as a normal process.
jluxenberg··on About speculative execution vulnerabilities in ARM-based and Intel CPUs
Apple patched Meltdown (not Spectre) for Sierra in "Security Update 2017-002" on Dec. 6th 2017. They are not doing a point release; the latest version of Sierra is 10.12.6

If you want to check that you have installed this update, you can use the following command:

  $ system_profiler | grep 'Security Update 2017-002'
jluxenberg··on Blackbird: Bitcoin arbitrage
And here's an instance of this very bug! https://github.com/butor/blackbird/issues/348
jluxenberg··on Blackbird: Bitcoin arbitrage
From the README:

  >> your maximum loss on an exchange won't be 
  >> greater than $xx no matter what.
Unless I'm misunderstanding; the bot sells short on one exchange and buys on the other. If there was a bug where it didn't cover the short sale with a long buy, and Bitcoin price goes up, you'd be liable for the increase in price.
jluxenberg··on The Impossible Burger
They serve this patty at Umami Burger in SF. We tried it a few weeks ago and everyone was really disappointed. It definitely doesn't bleed. It's cooked well-done and can't be ordered any other way. The taste is similar to a well-done beef patty.

I'd love to try the burger they're describing here. Maybe the product is difficult to work with and Umami is unable to get these results? Or maybe they're describing some version 2.0 Impossible patty that isn't available yet?

You've got to be kidding me.

Ladies' night is all about objectification of women. Spinning that as "gender discrimination" against men is sick.

jluxenberg··on The United States Postal Service Will Now Email You Your Mail
doe88 is talking about mail covers (https://en.wikipedia.org/wiki/Mail_cover), a program where the USPS provides copies of the information on the outside of envelopes to the federal agency requesting it.

This program is controversial because no lawful order is required for the USPS to collect this information. It's an egregious violation of US citizens' privacy.

jluxenberg··on A View of the Entire Netflix Stack
Netflix hires very few entry level engineers. I just checked their jobs page[1] and there are almost no postings for non-senior engineers.

I'd argue that a senior engineer should be highly effective while still developing in her role. Also, expectations for different "levels" of engineer vary. Typically an "exceeds expectations" performance review for "Senior SDE" would be neutral for e.g. a "Staff SDE."

jluxenberg··on Bill Gurley: startups seeking funding are starting to lower their expectations

  He said low interest rates have encouraged many investors
  to pour capital into private tech investing, fueling high
  valuations. If interest rates “stay at zero, rather than
  seeing a hard correction, you might start seeing volatility.”
VCs are investing in private tech companies expecting 10-100x returns on about 20% of their fund. Which works out to at least 20% return per year on a 10-year fund.

It doesn't make sense to me that an investor who would choose a VC fund as their vehicle would suddenly choose a Treasury note when interest rates go up 1-3%. A VC fund should still outperform that.

jluxenberg··on Prices for starter homes are crowding out millennials
Is the $800 amenity fee monthly? If not, you're probably better off buying (see http://nyti.ms/1han05C ; plug $300k in for the "price of home")
jluxenberg··on New Findings from War on Poverty: Just Give Cash
It seems that we can give money to those in need, and see a "return" on that money in terms of increased employment and generation of value. Sounds like an investment to me.

The government is the unique position; they are able to realize a gain on this via income tax revenue. Maybe this can be done via basic income? Could we pass a basic income bill as an "investment in America" and is there a model where the government actually makes a return on this investment?

jluxenberg··on [dead]
Many people around the world have a different experience. I'd encourage you to research other viewpoints before making a blanket statement that a certain relationship style "doesn't work out."

The book "Opening Up" by Tristan Taormino is a great starting point. (http://www.amazon.com/Opening-Up-Creating-Sustaining-Relatio...)
