Just theoretically if surveillance was good enough to catch every single crime in public, would this be "worth it"?

As noted elsewhere, when football hooligans had cameras installed to identify them, they scouted out locations where there was not surveillance. Criminals would learn to commit their crimes under the cover of a roof or awning. This would make people safer from criminals, while making them less safe from the authorities.

That's not true at all. He's fighting through tremendous resistance from various factions. From unions seeking to insulate themselves from private-sector competition, http://www.fairfaxtimes.com/articles/metro-to-use-contractor..., to urbanists demanding that Metro offer massively money-losing late-night rides to support "active nightlife": https://ggwash.org/view/70172/metro-needs-late-night-service.... He's taking a bold course that elevates long-term sustainability over temporary inconvenience, and quality of the core offering over trying to cater to every want or need. Lots of people disagree whether that is what needs to be done.

> And given how difficult it is to define insider trading that seems like a pretty accurate assessment to me. Alternative data firms are the new expert network firms in the wake of Rajaratnam.

I fail to see the parallel with Rajaratnam, since Rajaratnam was accused and convicted of insider trading on the basis of leaking from corporate insider executives(!) That's precisely the distinction that is being drawn in the comments here, between theft of insider information and the acquisition of difficult-to-intuit public information.

To answer your question, these parts:

> But technology is increasingly blurring the boundaries between public and private information, creating data opportunities that are legal, but are expensive and often require special expertise to access. “Technology was supposed to level the playing field, but what I see is the fence separating sophisticated and unsophisticated investors growing higher,” says Patatoukas, who is passionate about teaching his students to analyze public sources of financial information and finds the trend troubling. “That’s the dark side of big data. Our evidence suggests that unequal access to alternative data leaves individual investors outside the information loop.”

> In the aftermath of the financial crisis, there has been increased regulatory interest in the role of informed trading and disclosure requirements to protect the fairness and integrity of capital markets. With this in mind, Patatoukas hopes that the paper will get the attention of the regulators. “In a market setting where the line separating public from material non-public information is getting blurrier, the question that regulators need to answer is: What is their role in terms of leveling the playing field for individual investors?”

Firefox announced a couple of weeks back [1] that they would be blocking 3rd party cookies in a fashion quite similar to Safari's ITP.

Furthermore, they seem to be experimenting with the same 7 day limit for first party cookies [2].

Neither of these approaches is perfect, but it seems better than Chrome with regards to preventing tracking.

I think this is only true if you live in a major city. I live in the bay area, but I'm in Mountain View, not SF or Oakland.

That's going to add a good hour to the outing, which means it's just not going to happen for me.

Jet fuel is really about 12-15 MJ/kg when you take thermodynamic losses into account. So you;d need a battery 10 times as dense. Which likely isn't happening any time soon, but still.

I think with full electric aircraft it's not a case of 'won't work' but how big of a niche they can carve out. Probably the sector they'd compete in are general aviation and puddle jumpers.

Importing a list implies there is something to consume the list like an adblocker.

While this could and I think should be built into the browser having a complex enough addon system to build something like ublock origin ensures that you can always use best in class tools. As an example adblock plus was the best option years back until ublock origin came into being.

ublock origin uses less resources, improves latency, and blocks some things that adblock does not.

Had your hypothetical browser for techies standardized on building adblock plus into the browser you would be stuck with it for some years until they moved on instead of clicking a link in an addon store.

Complex tools always end up being about the ecosystem because core developers neither have man centuries to scratch every itch nor a monopoly on good ideas.

Insofar as you have an ecosystem distributing it via a central store or stores is a proven idea. You can make an informed decision to trust a store which can vet individual developers/companies and also make the decision to remove people who later abuse that trust.

Example stylish was used by many users then sold to scummy people.

Having your users browse the entire web and make the decision on the spot as to what to trust to run on their computer has failed so many times its hard to imagine it needs another try.

It's all well and good to imagine that a sandbox should be used to limit the access an individual app or addon is allowed to have but such cages always have weak hinges somewhere and furthermore people often want at least some apps to have relatively expansive permissions so that interesting tools can be built.

This leaves the users vulnerable to your hypothetical bad addon requesting permission to own the world and the user reflexively clicking yes.

At Series B things are more figured out in a company and they should be focused on scaling and growing. So frankly I'd be fairly unlikely to accept 30% below market from a Series B company, however you didn't specify if the base was below market or just below your current comp so hard to judge. You also need to make sure you are comparing apples to apples as far as comp.

Stock options or the like for a Series B company hold a bit more potential value IMO than a seed or A company. However, they are still essentially worthless unless and until the company is acquired or goes public. So you need to evaluate them as such. And a company not telling you the pool size or percentages etc is not being very transparent so I'd expect anything they give you to become so diluted it is worthless and you should negotiate comp as such. Not saying they are a bad company, just don't deceive yourself about the value of options and in a startup transparency around this type of info is pretty critical.

My 2 cents, don't go to a startup as an employee if you are trying to make money. Go to a startup because of the experience and chance to really put your mark on something as well as learn new skills etc. At Series B, that ability is starting to diminish some but still exists, so you have to judge the company and team on if you'd be happy. Just be cautious of low ball offers and promises of riches to come because in all likelihood they won't happen.

Not comparing the content library, but the cost here. Netflix is not very expensive compared to Hotstar or Prime. The latter two are targeted at family watching. They don’t have the concept of user profiles on a single account. If you have a family of four with each wanting to watch something different without trashing others’ watch lists, progress, etc., then with Hotstar and Prime you’d have to buy four separate subscriptions. With Netflix, you get five separate user profiles for one price.

Also, the quality of video and the user experience on Netflix is leagues ahead of Prime and Hotstar (in that order). Hotstar is very poor on technology and design. It only has its content catalog to lean on.

That sounds awesome. Ad-tech is a burden to society.

What's complicated with first-party cookies though? Didn't Apple for example just give them a limit of 7 days? I guess Apple just accepts that people have to log-in again after the 7 day period, but I haven't looked into the technical details about this feature.

Safety. A cat sleeping in your bed is the best guarantee against snake, rabies/plague carrying rat, etc. making its way unnoticed into the bed.

Those things are all good ideas, but they honestly don't bother me much. Perhaps SF is just a fairly savvy/respectful cinema audience, but I've very rarely had any distracting audience members. The advertisements and preroll clips are obnoxious, of course, but with reserved seating you can know when to show up to avoid most of it. And so it really just comes back to the audio/visual tech and the seating, and the local AMC and Cinemark are far and away the best in that regard.

Was going to make the same comment. I remember Peter talking about how he used foot traffic at the mall to size up retailers he was looking at back in the early 90's. These were interviews on channels like CNBC, so pretty widely watched by retail investors.

All the satellites do is automate the work and I'm pretty sure hedge funds have been using satellite pics for well over a decade now. (I recall reading about the parking lot use case pre-2010) So really all that's changed is that they're now using ML to automate most of the work that analysts used to do manually.
While the small pox/disease ridden blankets may or may not be factual, there is plenty of historical records predating Europeans landing in the Americas of using disease in warfare.

When sieging cities in antiquity water supplies would be contaminated. Arrow heads be smeared with poison and otherwise feces to cause infections. In Europe during Middle Ages corpses and feces of diseased would be catipulted into cities to cause infection, notably this this even happened with corpses that died of the bubonic plague.
That will also take away Hollywood's ability to be gatekeepers and tastemakers. That power distributed throughout the population will be a huge change.

There is a pre-paid T-Mobile MVNO called Mint who will give you 3 to 12GB/month LTE for $15 to $25/month, with unlimited at slower speeds when you go over your limit. To get those prices, you buy in bulk, prepaying 12 months at a time. If you need to buy extra LTE capacity in one month, they charge $20 for 3GB increments.

In reality though, I think many US users here probably get the majority of their bandwidth over WiFi and do not really use that much LTE data. But, if I wanted to replace my $70/month cable Internet with just a Mint subscription, i.e. the $25/month plus 2x $20 refills, that would buy 18 GB/month of LTE.
I feel like the should be a different name for that class of mitigations. Probabilistic security maybe? Security through obscurity for me is "we won't publish our algorithm". But that's not the same as ASLR or memory encryption which targets specific type of attack by adding probably-too-high randomness to the attack path.

A long time ago, an old-timer, even more old-time than me (and I did CS home works on punch cards in PL/I...) was a C fanatic, and was dragging his mainframe colleagues into Unix, said it best: "C does not get in your way."

He (and I) came from an era when eventually pretty much every language eventually "got in your way" and you had to learn the assembly language calling and linking conventions and implement a few nuts & bolts to get your job done. C was the first popular language that didn't eventually knee-cap you like that. That is why C won and Pascal was an intense but passing fad.

To me, that is the essential message for language designers, more important than "keeping it small". Stay out of the programmer's way. Of course, there are different ways of staying out of the way.... Python's "duck typing" is a way of keeping the type checker out of your way. Rust's "unsafe" is a way of keeping the borrow checker out of your way when you really, really, need to carve with your sharpest knife.

So I would argue that "applies to a wide variety of use cases" simplifies to: does not get in your way no matter what your application is.

As an aside: The old timer was a role model to me in one important aspect: Learning to recognize progress when you see it. He not only lived through the transition from core to solid state memory, he lived through the transition from transistor logic to integrated circuits. But he was evangelizing C and Unix when many his age thought the list of interesting programming languages had len()==3: FORTRAN, COBOL, assembly. I took that lesson to heart, and try very hard to answer the question: "Is this progress, or is this just different?".
