We are very far from trusted hardware. It's very easy to imagine what they would do - step one is helping American networks use the best practices - use open-source software, keep dependencies up-to-date, have bug bounties to find vulnerabilities in popular frameworks, etc.

Step two would be to consider some shared infrastructure, probably subcontracting with a cloud provider (AWS/Azure/GCP), hopefully multiple. Once we get to that step, then you can start considering things like Google's Titan (https://cloudplatform.googleblog.com/2017/08/Titan-in-depth-...). But there's a lot of low hanging fruit before we get there.
> e.g having thousands of cars at Burning Man.

Sounds like a great way to piss off the organizers of Burning Man and get a bunch of damaged vehicles. The desert itself is very damaging to car paint, nevermind how Uber operating there would be the antithesis of the purpose of Burning Man.
My understanding is that in a reasonably stable state, an autonomous car would run on battery, charge itself and cost 40k. If a car has a life time of 5 years and electricity costs 4k/yr + 2k maintenance (lower for electric cars), we are looking at operational cost of 14k/yr per vehicle.

Right now an Uber driver who is probably online 60 hours a week, needs to support a car priced around 25k (amortized over 5 years), gas (which is more expensive than electricity), maintenance and 50k-70k/yr driver income. Assuming lower end we are looking at 5k car + 10k fuel + 5k maintenance + 50k driver income. So cost to support a driving car is 70k/yr for lower hours of operation.

So we are looking at a 5x cost and lesser hours of operation with human driving vs autonomous driving.

These are off the napkin numbers so please don't take them literally. It is meant to highlight that driver income is the biggest factor.

Whoever has self driving tech, they can start undercutting Uber with the most profitable markets (NYC, SF, Boston, LA etc) and expand from there.

I feel that we are at least 5-8 years away from main stream self driving. But I could be wrong.
Same story as the solar roof, when they meet resistance they push some new fantasy that might never see the light of day.
The credit line needed for such a venture would be quite large, I doubt Uber could get such a credit line any time soon.
Networking on a New Level
That was just an example. Don't take it literally :)
I agree, but unfortunately building a business is more about implementation details than big goals.
Wow the logic games are pretty interesting (sample: http://www.admissionsconsultants.com/lsat/lsat-prep-game.pdf) They feel like Karnaugh maps and state machines to me :-)
> The other official reason is battery pack issue (could be related to welding, who knows). Again Battery pack is their defacto business, Tesla is essentially a big battery pack strapped into a car. They know how to put batteries better than almost anyone else in the market - if anyone can bounce back from this setback quickly - it's Tesla.

What you're saying here, in short, is "They're having issues in their core competency. Since it's their core competency, it'll obviously be fixed soon." Phrased in such general terms, it's actually not reason to be optimistic about Tesla's future.
The problem is 1) bicycles are made in Asia (for decades) for their market (we just import it), 2) so a lot of different manufacturers, 3) stealing bikes isn't such a big problem in e.g. China, 4) expensive gear catches of thiefs, a bicycle is easy to take (most sold locks are a joke, the good ones are very heavy/unpractical)

Better make the hi-tech stuff invisible, hide it in the bicycle frame - putting motors, akku packs, cameras inside the frame is doable. Some spend 5k to 10k for a new bike, so there is a market.
Funny script, though I can't help but point out a flaw: it doesn't play well with unbracketed conditionals. For example:

if (num > 5) goto foo;

will not behave as expected, because "goto foo;" is replaced by two separate statements, the second of which is outside the scope of the conditional and will always be called. Maybe they could fix this by tying the statements together with a comma instead of separating with semicolons? (EDIT: I don't think a comma will work, but adding brackets around the two statements should do the trick. JS doesn't seem to mind redundant blocks.)

Still funny though.
Particles are a really useful fiction. I'm having a tough time thinking of how to teach and explain chemistry without the concept of valence electrons. Do you have any ideas?

(Related tangent: a super important but occasionally missed nuance of quantum mechanics is that the waves are not waves over 3D real space. They are waves over configuration space, with way more than 3 dimensions.)
I agree with this comment so much, it hurts.

I think Australia plans to switch to full face recognition based immigration check in the very near future (next year) for its airports, as long as you have a biometric passport. So the whole process would be automated.
I could very well be wrong. Since we are all guessing here, my guess is as good as yours or anyone (who is not an insider and sharing the whole story).
This reminds me of the Derren Brown video about the subliminal effects of our surroundings [1].

I agree, we like to discount them, but acknowledging them very often also leads to arguments about the effect of all TV, music, games, general media consumption on behavior and thoughts.

It's real, but so hard to quantity, which leads to benefits for those who can and will exploit, but limits those who try to point it out.

This is why I think Tesla is a bigger threat to Uber in long term. If you are not sure then refer to Tesla's plan 2 but Uber also have a counter plan - UberAir

Hey, if it means I can keep my shoes and my belt on going through security, I'm all for it. Anything that is going to actually be effective, and not merely massively inconvenient security theater.

It's definitely early days for me, but I've recently shifted from all pen-and-sketch-pad to just getting more comfortable with LaTeX and entering more stuff directly into LaTeX. I find it makes me think more carefully. I've put some effort into getting immediate rendering on file change using Skim and various little bits of Emacs lisp to make LaTeX editing convenient. (I'm sure I've got plenty to learn about what the LaTeX modes that come with my editor can do as well).

I doubt asian produced bikes dominate the market in the west. See eg http://www.conebi.eu/wp-content/uploads/2016/09/European-Bic... - 7M imported and 13M produced in 2015. The asian industry is also much younger so the "decades" is not really an advantage.
This isn't a complaint, but the irony of me being downvoted to obliteration for posting a link to the NY Times calling bullshit on their own bullshit when someone claimed they never did it is gloriously amusing.

It's almost like people don't like bullshit being called on their allegations of lack of bullshit calling.

Arjun Reddy Tamil remake ‘ Varma ‘ first look unveiled
Nice to get a shout out with the GIF credit from my YouTube video. After I saw Casey Reas speak at Eyeo about the 10 PRINT book, I recorded that with Vice. While the other authors made a version, Slate for some reason used my version, and it was my 15 minutes I guess, heh. It is a great book, and I still flip through it now and again. This is a great post, and I have a lot of fondness for the C64 from when I was a kid.
do you know how rich I'd be if I could do that? ;)
Frankly surprised they aren't doing it already, or at least some other agency. The Europeans seem to be leading when it comes to some of this tech, though at least with GDPR in theory it's a rolling 30-day window of data and not anything too permanent.
I'm sure Bluespec, TSMC, SiFive, NXP, Samsung, Qualcomm, Microsemi, Micron, Huawei, and NVIDIA don't think of it like that, the RISC-V foundation is also not UC Berkeley. Also, strictly speaking the UC system ain't the state, if they were, they would not be allowed to generate copyrights from work produced by employees. IBM at least partially (if not completely) covered the fabrication of the original UCB RISC-V chips.

Though I'd generally agree in the case of IIT Madras, which is specifically engaging in a state effort to reduce import dependence in microelectronics (especially for defense and national infrastructure).
I somehow feel that Autonomous drones would be easier to build than Autonomous cars.

Benefits of Autonomous drones:

1. Do not need to deal other non autonomous devices while in flight. Cars needs to deal with human, other cars driven by humans.

2. Do not need to follow existing road traffic rules.

3. Lot of paths available. Cars are limited to existing roads. Drones can have a lot of flight paths.

I understand that there are other challenges - more energy required, less safe in case of an accident, flight regulations.

But still. It seems like if the technology is there, it would be an easier transition with Drones vs Cars.
actually we can't. Spacey's antiques are EXACTLY the reason I chose the photo. or do you think Tyrants can't also sexually harass others at work?
Low-maintenance and maintenance-free drive shafts are a solved problem

Shaft-driven bicycles have been a solved problem since the late 1800s. [0] But I’m too lazy to do the conversion needed to determine if 125 1898 dollars is expensive. Bikes in the 1800s were priced more akin to modern cars than modern bikes stamped out in an Asian factory. But it’s been done, and by what was a major brand at the time. I’ve ridden them, they’re heavy (like every other bike back then), but nice to ride. I don’t see why it couldn’t be coupled to a modern set of enclosed planetary gears.

Electric steering? But why?

Lights: I bought a $15 set of lights off eBay ~3 years ago. The alkaline AAA batteries need replacing a few times a year, nobody can be bothered stealing them because they don't look expensive.

Why all the cameras?

Why an electronic lock?

As for locking both wheels, in my experience changing from QR dropouts to something that requires a simple tool for taking wheels off solves that problem. The tools on my bikes are small enough that I Gorilla tape them to the underside of the seat on each bike.

As for shocks being maintenance-prone: my daily commute is on a bike with Suntour shocks from 2002. They've never had maintenance. Basically everything else on the bike has been replaced except for shocks and frame.
Well, I think intrinsic ineffeciency of storing all that data inside your central and then running huge spark jobs to crunch through them creates huge costs in the first place that probably needs to be offset by higher margins being charged from the end consumer. If you can just monitor the users engagement with your offering and charge on that without having to actually go through countless logs to do that, might be what the author is leaning to. But yeah, easier said than done. Knowing which metrics to capture back centrally itself could be a challenging thing to do, if the data is decentralized ....
I do believe Germany has the best protection laws for keeping sources secret. Not sure it says in the article. I haven't read it yet.
I think it's safe to say that "you can do" here means "it is possible to, and people do".

The risk Facebook would take by pulling a stunt like this is ginormous. See also: Amazon Echo.

The consumer and legal backlash would be swift and stunning, and the secret would be impossible to keep. Mobile app decryption is a well-established process. Reverse engineering a large app is tedious, but fully comprehensible. If you're specifically looking for recording (streaming audio out, or spooling to storage), it's much more manageable.

Of course there's a danger in assuming that someone, somewhere has already done this (or many someones). ~"With enough eyes, all bugs are shallow" ... sure, if the eyes are open. I don't know anyone who has done this work for the Facebook app, or for the Echo. But there are so many little boutique security firms out there today, and the technical prerequisites are so low...I just don't see how it's possible that it hasn't been done a hundred times.

The genuine risk, I think, is that a Corp with all the tooling in place could be compelled by some vaguely legal process in some sketchy jurisdiction, to target an individual of interest with custom code. This isn't hard either. Of course, the "tooling" is minor and any popular app could be subverted usefully in this fashion, so Facebook is not special here.

Still, most of us are laughably uninteresting to LE, but proper opsec still dictates caution.
That ex-NSA guy calling his company "Rendition Infosec" -- how disgusting. Gives insight to his character.

Whoever solved self-driving cars could buy 10,000 cars per city. Let's say each car costs $100,000. That's $1B if paid upfront which is never the case, but let's assume.

Now, each of those 10,000 cars could work 24x7. Assuming each ride is $10, and you can do 50 rides in a day (2 trips per hour on average over the entire day), that's $500 per day less electricity and maintenance. That's $5M/day with no employee costs except for maintenance workers. You could scale up by simply buying more cars, and whichever cars aren't needed could roost at homebase, without people picketing or sending nasty tweets saying they don't have enough work.

I doubt you have to pay for marketing costs at this point, word of mouth would be strong enough, and you just develop an app.
Transferring files locally is still an unsolved problem. Bluetooth is cumbersome and slow, WiFi would be better, but something like AirDrop for non Apple devices would be great.

For SD-cards, many Android smartphones can be used to read it. Unfortunately iPhone has no SD slot.
> Most of the people on the planet have grown up watching blatant misinformation being broadcast on TV, radio, and print.

Misinformation isn't the new problem. The problem is that people who believe the misinformation can find each other more easily via social media, and amplify the message. Due to a human cognitive quirk, we tend to lend more credence to statements we've heard repeated from various different people. And so, powerful but false messages can more easily spread, and when those messages serve a motivated political agenda...

If f() returns a value then you have a problem and should fix it, but if f() instead returns a reference (that is not dangling in itself), then it should be fine.
Watching this recording I really wished they would invest more in audio equipment and in people who know how to record it. Reminds me of a lecturer at uni who had a bunch of recorded quest lectures that he would show every year. Audio on those was terrible, constantly clipped sound, but when we complained he said he couldn't hear anything wrong.
Vivaldi does this for me in the history page itself. Pretty weird to use Python just to see a distribution of what sites you visited.

I like this part "it draws its results from its own bot that crawls the web". There aren't too many that use their own bot.

Wanted to add that I'm currently on Opera and using an extension named Search All[0]. After conducting a search via your default search engine, this extension places a bar with a list of user configurable search engines. This allows you to search alternatives easily using the same keywords.

One great feature is that if you go directly to a search engine, click on the Search All icon, it almost always identifies it with correct parameters and can be easily added. Just added findX to my bar (for testing).

I plan on going back to Firefox and wish FF had something like this (part of the reason I'm posting this).

You can pick a blue and a yellow and a proportion at which to mix them which will produce white, but for any two primaries you pick, there are a multitude of colors you can't represent. For example, if your basis is blue-yellow as you suggest, then you can't represent red or green (and an infinity of other colors off-axis).

Fundamentally the chromaticity diagram[1] is 2D (with a third axis for intensity). You need to mix at least three points to span the space of the plane.

To be honest though building a processor these days is not exactly difficult. That is especially true if you start with someone else's ISA and they have already created a GCC or LLVM back end for it. I was at Sun during the development of SPARC and as part of the Systems group we got to see a lot of the trade offs up front but these days transistors are not nearly so scarce. If you stick to 30 - 50Mhz for your first round you can simulate pretty much power on to shell prompt in a reasonable amount of time. Then there are the process specific issues that TSMC or Global Foundries or whomever will help you with translating your HDL into their most reliable node (probably 45nm or 90nm at the moment), then you'll build a test chip and it will likely do everything you want it to do and it will cost 10x what an equally powerful ARM chip will do, so you will really really want to use your chip instead of that one if you're going to design it into something. And that something has to be popular enough that you sell at least a million of them, otherwise you're going to eat a lot of Nonrecurring engineering (NRE) cost.

It is certainly possible, but it is a long game and you have to survive the early years. Go back and read the history of ARM (and Acorn), Intel (and IBM), Motorola (and Sun and Apple), and Power PC (and Cisco). Then read the history of the Z8000, the NS32032, the AMD88000, and the TI 9900. When you look at the history from where we sit today you will see that building a new CPU is the easiest thing in the world, staying alive until it is relevant is exceptionally difficult and requires quite a bit of luck in addition to good design.

I wish these guys a lot of luck, I would love to see a fully open architecture be even half as successful as ARM has been. They have to walk into this with their eyes open though, it is not going to be easy.
