tma-1··on Welcome Chris Lattner
It ultimately depends on how much of the car's action is driven by DNNs, a miss-classification in the CNN can easily lead to a car crashing on a highway and causing a pileup. DNNs are so complex, you can't really write unit tests like you typically do for deterministic code.

That's why some of the big banks flat out refuse to implement any form of deep learning for risk analytics. They're much more reliant on simpler ML models like random forests and logistic regression that are easier to analyse and diagnose by model governance teams.

Well considering that most of the autopilot software is driven by black box deep neural networks, I don't think hiring someone with a strong coding background is going to make that much of a difference when it comes to safety.

tma-1··on Foxconn replaces '60,000 factory workers with robots'
No we don't, I am not anti-progress but my personal opinion is that increased automation will lead to further inequality and potentially economic contraction. Thing is, we are not born equal, different people have different skills, we can't be expecting everyone to become an engineer or a scientist. Blue collar workers losing their jobs will not lead to interesting times...

Have you tried tuning Spark's memory parameters?
tma-1··on Spark as a Compiler: Joining a Billion Rows per Second on a Laptop
I have been extensively using the dateframe/sql API and I just love it. Most of the issues I have had stemmed from the cluster / Spark configuration and not the API itself. Using SQL is so much more intuitive them using multiple joins, selects, filter etc on an rdd.

tma-1··on How the Jeans Capital of the World Moved from Texas to China
Well consumers won't be able to buy their $30 jeans if they're produced locally... This problem is just as much about consumers wanting lower prices as it is about corporations wanting to make more money.

tma-1··on iPhone Sales Drop, and Apple’s 13-Year Surge Ebbs
> The Company also announced that its Board of Directors has authorized an increase of $50 billion to the Company’s program to return capital to shareholders. Under the expanded program, Apple plans to spend a cumulative total of $250 billion of cash by the end of March 2018.

My god, that $50 billion expansion is 7% of the company at the current market cap.

Ad blockers block those by default.
tma-1··on Alphabet slides 5% after missing earnings expectations on revenue of $20.3B
Long-term, I am not very bullish on Google/Alphabet. More than 90% of their profits come online advertising, something that can be easily blocked for life with a simple browser extension/plugin. Some worrying figures[1]:

* US ad blocking grew by 48% to reach 45 million active users in 12 months up to June 2015.

* Ad blocking grew by 41% globally in the last 12 months.

* US ad blocking grew by 48% to reach 45 million active users in 12 months up to June 2015.

tma-1··on Intel to Cut 12,000 Jobs, Forecast Misses Amid PC Blight
Yes it's permanent. Interest rates are still super low, meaning companies can still take on debt to buy back their stock. The effect of quantitive easing remains until interest rates start going up and the Fed start buying government bonds from the banks.

Both GS and MS (as well as other FIs) are off there highs because of all the volatility in the markets the past 6 months and worries about losses from bad energy loans. BAC, WF, Citi are all off their 12-month highs by a significant margin despite doing relatively well in Q1.

Also, this has nothing to do with discounting the cash flows, it's mostly stock buybacks that's driving all the action:

I am not surprised. I am a huge fan of Thiel, his book Zero to One was a real eye opener for me.

Have you been following the current earnings season? We are witnessing horrible earnings while stocks keep going up and up. All the losses in August 2015/February 2016 have virtually disappeared after the oil price recovery.

I would bet they want restructure so they can do more stock buybacks...
