There is a great talk on some of the dangers: https://www.youtube.com/watch?v=HKQDSgBHPfY

News article if you can't watch: https://www.theguardian.com/science/2017/jul/31/bioweapons-c...

tl;dr “The reason you haven’t heard much about bioweapons is that they’ve been held back by a pretty severe limitation, which is the potential for blowback." Unlocking the ability to target specific genes will overcome this since the same tech that allows targeting only cancer cell will allow targeting specific groups or individuals.

> What, for example, if groups spread their agenda in a very direct way, by literally rewriting DNA to make it impossible to live a life against their credo? Suppose militant vegans wanted to end meat eating: there’s a gene for that. Or imagine if radical misogynists wanted to force the veiling of all women: there’s a gene for sunlight intolerance, and the genetic functions of gender are already well-known.

> Or, he suggested, attacks could be done on an individual level: targeting public figures by stealing their genetic code, or targeting their whole family by sequencing the genes of someone who’s closely related. And the attacks could be subtler than what’s expected: Sotos cited genes for intractable diarrhea, massive weight gain, total baldness and “an intense fishy body odour”.
I'm not complaining. Merely expecting, given that this is not the first time I've posted something similar, and I felt the need to point out the double standard ahead of time this time.

Downvote away! I just hope that the hypocrisy is clear. edit: Or there may be a totally non hypocritical reason to downvote me, which I would also encourage.
In raw "what is possible" terms I cannot fault you. But I really like the idea of fundamentals, and "what is likely" is a different kettle of fish.

In a sense, share prices compete with the cost of starting a new company that does the same thing. P/E ratios of 230:1 mean an increasing risk that instead of someone buying your shares, they go and start a competitor. Then everyone buys that competitor instead.

In any market there is an upper limit to the P/E ratio, and nobody wants to be the buyer who finds it. Especially if the company's income doesn't rise; because then you have to sell at a loss to recover any money.

In practice, there is also the risk of catching a collapse in the market. They happen that, once every decade or so? Great time to be able to rely on an income stream when that happens.
An obsolete version that runs faster and benchmarks better, which some customers won't realize is less secure? It doesn't seem unlikely...
This view ignores revenue growth. If the company is growing like a weed it may choose to reinvest everything and keep profit near zero. If there's no dividend the profit would just go into a war chest and collect some minimal interest rate. If the company thinks it can get a better return on investment by spending all income on growing itself it has every reason to do so, and all it has to do is beat that minimal interest rate. The only reasons not to: you have no ideas where to spend your own money to result in growth, you expect that reportable earnings will look good to some investors, you want a war chest to make some giant acquisitions, or you're planning on starting to issue a dividend relatively soon.

Amazon has always had near zero earnings. Over the last 10 years its grown from ~$17 billion revenue to ~$140 billion in revenue. Yet they have almost no earnings! Barely profitable! It's wild and irresponsible! Yet Amazon is not on the brink of collapse. Despite near 10x growth their earnings have always been completely flat, near zero. Why is that? They're not booking earnings because they can't, they're not booking earnings because they're choosing not to, by spending it on growing themselves. It could be seen as a good thing: Amazon has lots of areas to invest in itself, if they didn't, maybe they're running out of ideas. Netflix has also grown by about the same multiple over the same time period as Amazon.

Now, on the other hand, Netflix's price to sales is about twice that of Amazon. Amazon's price to sales is about the same as Apple.
Clojurescript is also very mature and has a pretty great community and set of open-source libs
> You know it is also "outlawed" for most European cities to build too high vertically too right?

What's the justification for that?
False. Everyone who decides to use a bus/train instead of a Lyft counts as a public transit user. In aggregate, our decisions determine how many riders use public transit. It serves no purpose to ignore anyone who rides less than 30-40 times a month (which is around what you need to break even on a pass)
I’m 36, live in the suburbs, and in recent years have gone (legally) blind from Retinitis Pigmentosa. Voluntarily giving up my license was one of the hardest and most important decisions I’ve made. There is literally 0 public transportation here. Not even Uber or Lyft have come around.

America’s sprawl and dependence on cars is incredible. It wasn’t until I spent time in London, Oxford, and Paris that I could recognize how much everything here is built around the idea of owning a car.

So now my wife has to give rides to our four kids, AND me, and there’s literally nothing I can do about it except petition for better transit, and pray self-driving cars get here faster.

Being dependent on rides feels like being 15 again. It’s humiliating being picked up from a job interview in a parking lot with 200+ cars.
> Unrestricted gene editing in humans is probably a bad idea

Isn't this what the point of testing is for? To find out if it is "probably a bad idea"?

> genetic "diseases" give an evolutionary advantage

Touting the amazing evolutionary benefits of CF isn't really helping your case. Sure you (maybe) can't get cholera but you will likely die by 40!
How obvious is the data recording on a Tesla? There's always a chance an inattentive driver will blame the smart car.
Wait, so is non (human-) visible wavelengths not part of the autopilot system?
People keep saying this. But are have you also thought about how wasteful is Facebook or Instagram or Youtube are? Do you know how much electricity Facebook burns running computers to serve fake images and shitty news? Or Youtube serving Logan Paul videos?

If we really care about the environment we wouldn't be playing this game of trying to say one kind of environment destroying energy consumption is okay but another isn't. We would instead argue to directly solve the root problem, which is dirty energy polluting our environment, by making sure energy pricing covers that cost. That way the market can tell us if Logan Paul videos are more valuable to people than say Bitcoin, and we would actually do something to fix the environment rather than simply making it cheaper for one energy consumer (Youtube) to pollute at the expense of outlawing another (Bitcoin).
Have you considered moving to a region with better transportation support?

Is anyone else finding the use of the first person singular in this post annoying? ("I apologize" vs "We apologize"). The previous post was the same. Since this was certainly highly edited by corp comms, it's hard to believe it's coincidental. It's as if Intel as a company is not taking ownership.
Well that will teach you not to trust Google, won’t it? The cost is $2.5 to $2.75 as I indicated: https://www.sfmta.com/getting-around/muni/fares

Please don’t start a conversation with a rude tone and then cite incorrect info to “correct” the facts that I provided.

As I’ve already mentioned, Lyft and Uber have frequent rider passes too so it isn’t fair to compare a single Lyft ride to the cost of a monthly bus pas per ride.

Monthly passes have also gone up $12-14 compared to what you cited. The bus is a great deal if you pay prices from 5 years ago ;)
Great analysis... I like your 'outshine the master comment'. There is a good chance that the OP is intimidating the interviewer and should make an effort to display humility to counteract this.
Converting energy from chemical to electric then mechanical is only beneficial if you need a high torque at low rpm, like to start moving a train. Otherwise its more efficent to directly convert from chemical to mechanical.
Yep. But as others have said, it's not really isomorphism in a mathematical sense. The article defines "Isomorphic web applications" as "where the web server and the web browser (the client), may share all, or some parts of the web application code." Just, "same shape" on both sides.

If it was identical code, I would (mathematically) call it an identity (which, to be fair, is an isomorphism).

But it's not identical; they transpile go to js ("GopherJS - A compiler from Go to JavaScript"). This compilation itself is arguably an isomorphic mapping, with the same code doing equivalent things on both sides. e.g. equivalent assignments between equivalent variables.

Two problems with this interpretation (1) a transpiler doesn't have to be isomorphic (e.g. could use different idioms); (2) that's not really the aspect they're referring to.
Yeah, in my experience Five Guys doesn't really compare. They're run well but nothing exceptional.
> rich people own cars, you see.

The irony is that in Silicon Valley, the rich people ride the bus.
The Useless Concept of ‘Calories’
> Flexibility is a disadvantage

This is what I was going to say. A rail line encourages development and densification around the rail line. Being "x minutes away from the train station" is a selling point for apartments and it can even create whole new commuting suburbs. At least this is how it works in Europe/Asia
I can't say for sure, but I would strongly imagine that they would want any managers they hire to be intimately familiar with the culture.
So I could see that even if they did hire externally, the applicant would need to train through one or a few different jobs and become acclimated with their way of doing things.

But I'm seriously only guessing from what I've seen of companies with really strong company cultures.
Tesla, to save money, is trying to build autopilot from regular video cameras in visible spectrum. EDIT: Some models still contain other sensors, but Musk has been trying to go with purely optical for a long time.
I've been using a private tracker for the past couple years, and I know some of the larger public trackers have been shutdown.

On the private trackers I haven't found trouble finding mostly anything.
Well, to be fair, the life expectancy of people who check their blood sugar multiple times per day IS substantially lower.

Why not phones?
I think it would be useful to write up a technical article on the cache side channel attack and how it is used by meltdown and specte and their different methods of exploit.

Maybe that would shed some light on who needs to worry and why.

I'm surprised the js jit writers have escaped with so little blame for Spectre since in the end it is basically just a process reading its own address space (I'm actually surprised more of these vulnerabilities don't exist since things like proc/dev/run are ripe for abuse).
I expect they're symptoms of the same thing. They keep discs until someone returns them as not readable. Then they chuck them and don't replace them.

I can't say I've had a particular problem with bad discs recently but I also have a minimal plan so my sample size is relatively small.
This is not hype. See here: https://rajpurkar.github.io/SQuAD-explorer/

In this benchmark people or models are given a text, and later asked a number of questions. Questions are quite real. See for example here: https://rajpurkar.github.io/SQuAD-explorer/explore/1.1/dev/S...

Models already have performance which are as good as human's. This is real. This is not hype.

What else do you call the process of coming up with a definition for, say, a second or a metre?
>"The flu often has a value of around 2, meaning the average infected person will infect two others before they're over it."

The R0 value refers to the potential for infection (ie in a 100% susceptible population it would be what you wrote).

>"But on a society-wide basis, if every person were vaccinated, that would effectively knock the R0 value from 2 to 1, which is huge. Transmission is exponential: if you infect two people and they infect two people and they infect two people, etc., the total number of infected looks dramatically different than if everybody only infects one person."

I just wrote a little SIR model and did not see this behavior. Depending on the parameters either 100% of the susceptible population was eventually infected, the infection died out quickly, or, if turnover was high enough (eg birth/death/viral mutation leading to a constant stream of susceptibles), there was a cycle and about the same number of people got infected either way.

Do you have a source for this behavior so I can see the details of the model?
Has there ever been a successful telecom that did not have government contracts?
> "what did you hack lately" question.

Is this part of the application anymore? I took a quick look and all I could find was

"Please tell us about an interesting project, preferably outside of class or work, that two or more of you created together. Include urls if possible. "

"Please tell us something surprising or amusing that one of you has discovered. "

both of which seem to be, at best, sanitized versions of the original questions which IIRC referred specifically to hacking systems, and impressive achievements of founders.

(If somebody has saved the original questions from the PG era, could you confirms this?)
> The California Highway Patrol and Culver City Fire Department confirmed the southbound Tesla had struck the fire truck, but could not immediately confirm whether the vehicle had been on Autopilot.

It sounds like it's not 100% confirmed that Autopilot was at fault. The first sentence of the article also reads "reportedly on 'Autopilot'"
The 12 month forward earnings yield of S&P 500 was 5.4% as of last Friday, with a minority of analysts having updated their earnings estimate to incorporate recent tax rate changes. That yield means there's still an equity premium, even if earnings stay flat after 2018.
The Berlin intracity rail system is outstanding. I used it extensively there.
> What am I missing?

Shorts? Conventional wisdom states that a 51% attack would destroy the very same value it would misappropriate, but when you can bet real money on BTC crumbling you get an entirely different playing field. Still very unlikely as everybody with that kind of hashrate is already rewarded far too handsomely, but if someone ever offers shorts on one of the smaller altcoins, I'd almost expect someone to state an at least cost-neutral attack just for kicks.
I realize this is the exception and not the rule, but it's great to see that fast food chains can make incredible profits while paying their employees significantly more than the competition. There are so many restaurateurs and investors claiming it's impossible for the fast food industry to survive the $15 minimum wage hike, but I suspect it will just make this already cut-throat space even more prone to failure.
I have. I’d have to move out of state and into a fairly urban city to get decent transit. The schools here are fantastic and I love just about everything here, except the lack of transit.

We may get to that point, but for right now I work remotely (platform engineering) and just grin and bear the rest.
If you are a tech company... Yes.
Even Dan the creator of Redux says you don't always need Redux and I got along fine without it for a basic app. I was writing clean React code within a day. The component lifecycle took maybe two days to understand? It's so simple I wrote a popular answer about lifecycle on Stackoverflow within a couple weeks of learning it. Want to write a big app with complex state? Sure, you'll want to add Redux to the mix. But it's not a hard requirement and is overkill for small simple apps. You can learn React itself very quickly.
This reminds me of how MIDI files [0] represent time offsets, in integral "delta-time" units which can be set to either an arbitrary unit fraction of a quarter note, or an arbitrary unit fraction of an SMPTE frame (which itself can be specified in frames per second). Combined with an ability to dynamically set tempo (at any delta-time offset) in microseconds per quarter note, this allows practically any (Western) music to be represented with just integer delta-times between notes, including crazy tuples and polyrhythms, in a tempo-independent way; just find the greatest common denominator for your subdivisions. You could have thousands of minute tempo changes over the course of a performance and never lose fidelity due to rounding errors.

Apple's (formerly emagic's) Logic software actually made this visible to the user, using 3840 delta-time units per quarter note and presenting an Event List interface [1] where you could edit integers for offset and length directly. As opposed to other WYSIWIG notation software like Finale and Sibelius, it felt like Logic was hiding nothing from you; you could be sure that everything you saw and heard was rendered declaratively from the same underlying data. Moreover, if you were ever having trouble zooming/subdividing the drag-and-drop user interface for whatever crazy triplet sequence you wanted, you could just break out a calculator and specify exactly what you want, knowing that you wouldn't be "fuzzing" anything by typing in a rounded decimal number.

(It's a good lesson for us as developers - while it can be extra work to build an interface that doesn't hide complexity, professional users will often figure out how to use this to work around other shortcomings in your interface, buying you time to fix them the right way. It's just a matter of finding the right abstractions - representing time as integers is just one example.)

needlessly opening/closing channels also costs transaction fees, so as long as most users are rational, this wouldn't happen (too often).
Yep, I saw 127.0.0.1 for an A record about 20 years ago.

It was discovered when going to that name outside revealed what seemed to be a copy of our own internal webserver!

What had happened is that our webserver was on the same host as our squid proxy. So we were in fact seeing our own site under the external name.

Protection for this sort of thing is in the default squid conf these days (from memory)
Big data is not AI. Big data is processing of a giant datasets with quite classic models, such as Logistic Regression in a distributed way. That's what frameworks such as Spark and Hadoop do. AI or deep learning is different. Usually, they don't distribute across many machines so well.
That might change when you are in competition with the ISP, as Comcast does with a ~30% stake of Hulu. Then you might start to care about net neutrality a lot.
Supposedly they're launching in February, but I guess we'll just have to wait and see.
People have been safely and intelligently using cruise control for... decades? It is a partial automation solution that reduces half of what you have to manage when controlling the car (how fast you're going).

I suspect the primary problem is not the partial autonomous technology, but the marketing which is convincing people they can trust it. Nobody ever told you your cruise control means you don't have to pay attention, so very few[1] incidents happen due to misuse of it.

First and foremost, Tesla should never have been allowed to release "Autopilot" being called that. From the very name it provides a false impression of what it can do.

Architechts, except Landscape and Naval (which also excludes Software Architects, which are in a completely different high-level category) make a median salary of $95,070 in California (about halfway between your Glassdoor info and what the article has from Indeed), per the federal Bureau of Labor Statistics, which has much more complete data than either Indeed or Glassdoor.

Not leave things up to chance?! Is the universe not inherently probabilistic? I'm guessing you mean make things a little more deterministic than they are now in terms of human evolution? Maybe, but I think its important to ask whether or not we already exist in some sort of thermodynamic equilibrium with the rest of the universe (on an evolutionary spacetime scale).

I also think it's not totally accurate to say that most species have gone extinct vs have evolved into something else.
The New Urbanist movement tried to recreate dense, mixed use, walkable neighborhoods like were the norm in the past. It was an uphill battle. They would take their plans to city hall and get told it could not be approved. They would then carefully scrutinize the zoning laws, rename some roads and other features as something else, rinse and repeat until something resembling their vision could get approved.

In most parts of the US, you can no longer build those dense, walkable, mixed use neighborhoods that make it convenient to live without a car.
As long as there is a human variable I severely doubt we will every get to a system that is 100%. The raw truth of it is to make a system that can do it close to 100% you need data. Tesla has chosen to put a semi-autonomous system into the hands of consumers in order to generate the massive amounts of data necessary to achieve full automation. Other companies have chosen to log a crazy amount of hours using technicians to generate the same set of data, both have and will continue to experienced crashes as they work toward making the system better.

Tesla I think has done a fantastic job at striking a balance between getting something into the market the generate real-world data and mitigating the risks that come with it. If this car really did crash into the fire truck at around 65 MPH then it did a pretty good job at keeping everyone safe.

I think I would be hard pressed to find any technological or mechanical innovation that did not initially involve risk or have an accident associated with it. I've seen more examples where a Autopilot has done the right thing and avoided an accident than I have read stories of it making a mistake and causing an accident.
> If I have a property that borders federal (public) land, must I grant access?

Depending on if there's an easement on your property, yes. These kinds of things are usually spelled out clearly in real-estate deals. A lot of homeowners on the beach think they own the land up to the water but that's not always the case despite them trying to block access. No one has to necessarily cross their property to get there either.
Montana is also the state that tried to pass a gun law that didn't require federal registration if the gun was made, sold, and used in Montana. Federal courts struck that one down.
