GM is full steam ahead on Robotaxis. Here's a PDF of the slides used during GM's investor presentation:
https://www.gm.com/content/dam/gm/events/docs/5265893-685163....

Some fun facts from the presentation:

> Cruise has 1,200 employees, up from 90 at acquisition in early 2016. (Vogt just specified only 400 are full-time at Cruise) Planning to have ~2100 by the end of 2018.

> They intend to get up to 1 million miles/month of testing in 2018.

> Their 3 simulators run 150 simulations per minute. Cruise CEO Kyle Vogt repeatedly emphasizes Cruise's high rate of improvement.

> Their test map of SF shows they're staying off the freeways, but they're pretty much everywhere else.

> Cruise is focused on an initial deployment in SF, but sees value on testing in other cities to prevent overfitting for the SF driving environment. They also test in Phoenix, and are planning to launch in NYC.

> Cruise projects It will take about 6 months to map and prepare for scaled deployment in a new city.

> They expect to get Lidar costs down to ~$300 (either per vehicle or per unit, not specified) with their recent acquisition of Solid state Lidar startup Strobe.

> Their vehicles currently have 14 cameras, 3 articulating radars, 8 regular radars, 5 lidar units, and 10 ulrasonic proximity sensors.

> They're projecting they can get the cost of an AV to under $1.00 per mile in 2025.

> They project 20-30% margins after 2025.

"on the surface" is used when you're either arguing the opposite or leaving the door open to being wrong because you know there is more to be revealed.

"it looks like" can be used in place of a more definitive statement. "on the surface it looks like" is almost never used that way.

I don’t think that the existence of marketing firms involved in decentralized technologies is anywhere near as significant or mind-blowing of a point as you portray it.

There is no reason to expect or desire that, because Bitcoin is decentralized, there will never be any private for-profit organizations involved with Bitcoin.

Surely you wouldn’t say the same thing about, say, email. I’m sure marketing firms have worked with companies that offer services involving email.
That doesn't really fit the way web-crawler-based search engines work.

If the search engine is working properly then if the new site looks the same to users it ought to look the same to the search engine. If Google's crawler didn't find the new site at all then they need a better crawler.

Maybe this was incompetence rather than malice on Google's part, but it was one of the two.

(An exception would be if you migrate a site and mess up your robots.txt or similar to forbid the search engine doing its job. But evidently that didn't happen here because the fix was at Google's end.)
This is doable but unappealing as the OS will see the display is gone, and relayout the desktop environment every time you switch. Depending on your OS, and your personal concerns about all your environment behaviors, you might not care. I know I would be very annoyed by this.
True, but that doesn't necessarily make a company hard to start. There are a zillion niches in transport that could be profitable places to get traction. Uber Pool and Lyft Line might be the future of cheap transport, but as Uber itself shows, you can have a decent business just at the high end of the market. There are several companies in the rides-for-kids department. Taxis do a significant business in hospital-specific transport, both of patients and of urgent medical delivery.

To start a rideshare company, you only need to do reasonably well in one segment in one geographic market. Then you have a basis for expansion into other areas, other segments. Contrast this with a search engine, where people really expect you to be good for everything and covering the entire internet.
Reinvesting for growth is a terrible euphemism for subsiding taxi fares.

My girlfriend used to be the director of special ed for two charter schools in The Bronx (Hunt's Point). The rates of asthma there are off the charts because it's where all the roads/freeways converge on their way into Manhattan. It's also the poorest congressional district in the US.

2. Recommend a website that provides collaborative paper annotation?

The argument is that Bitcoin is a decentralized, globally distributed Ponzi scheme, in the same way that it asserts itself to be a decentralized, globally distributed payment network. It seems unfair for Bitcoin proponents to go around saying "it's gotta be centralized or it's not really X".

Additions have certainly been made since back in 1998 (things like smart pointers are relatively new on this scale, as far as I know). Many runtimes for resource-constrained embedded systems do not support all of C++'s features. Exceptions are the most usual omission.

You can certainly strip things down to a subset that can fit 128K of flash and need only 1 or 2K of RAM at runtime, but the question is not only one of computational resources used for the library itself. Additional code always means additional bugs, the semantics sometimes "hide" memory copying or dynamic allocation in ways that many C++ programmers do not understand (and the ones who do are more expensive to hire than the ones who do not), and so on. You can certainly avoid these things and use C++, but you can also avoid them by using C.

I agree that mistrust and politics definitely play the dominating role in this affair though. I have seen good, solid, well-performing C++ code. I prefer C, but largely due to a vicious circle effect -- C is the more common choice, so I wrote more C code, so I know C better, so unless I have a good reason to recommend or write C++ instead of C, I will recommend or write C instead. I do think (possibly for the same reason) that it is harder to write correct C++ code than it is to write correct C code, but people have sent things to the Moon and back using assembly language for very weird machines, so clearly there are valid trade-offs that can be made and which include using language far quirkier than C++.
Yeah, it's the reason I just went straight to tearing them all out. There is literally nothing ADT's whitelabeled sensors do that standard Z-Wave devices can't at a third the price -- or less! -- without tying me to any specific security company. If I decide to move to any other HA system, I just replace the hub and pair my existing devices back up.

In fact, ADT's latest move seems to be piggybacking on Smart Things for HA, but... since I already have Smart Things what do I really need ADT for?
Pretty much. But Windows snapshots aren't writeable after you take them, which is a major downer and a major necessary feature. (Having this feature lets people do things like "Take snapshot and delete everything except *.lic files, under C:\Users, on every backup" and you can just issue deletes to the shadow volume after it is consistently created, and intercept the new deletions, like normal. Tracking deletions like this lets you more easily know what you should/should not back up -- only back up the allocated blocks in the shadow copy.)

So, there was a thing that added this feature to the Windows kernel in the product to make this work. Aside from the Linux stuff, which was totally separate. But if you don't need the writing capability, Shadow Copies are good enough, sure..

> And this is where the "promise" of anonymous currency/assets falls apart.

The "promise" (future vision?) of cryptocurrency is that you won't have to sell it, ever. Do your business, buy your groceries, pay your mortgage and taxes in it.

Whether that's realistic or not I haven't the energy to debate on HN. But it is certainly incorrect to say that bitcoin/USD exchanges have any sort of place in the cypherpunk utopic vision of a cryptocurrency future.

I generally agree with this, however if Softbank easily fills their tender offer I wonder if it puts a crimp in the IPO plans. Lets say that Softbank's tender is filled with a bunch of executives and Kalnick contributing their shares to get a payoff (shades of Groupon's last raise before going public). What does that look like to potential investors on the roadshow? How much bump will they need to be 'promised' before they subscribe?

I don't get all the hatred for ICOs. Nobody is forcing anybody to invest in them, and for something like filecoin there is at least a chance of something extremely useful coming out of it. Many other ICOs seem pretty strange to me, but as long as I am not forced to invest in them, what's the problem?

Rich people are only rich because poor people aren't willing to kill themselves in large numbers.

The best thing any individual can do to reduce inequality is to only contribute to institutions that do not exacerbate inequality.

Is the median wage at your company less than the wage required to buy the cheapest home within a 2 hour commute of your office? You're likely exacerbating inequality every single day.

Are one or more people at the top of your company working on buying their next Ferrari or second/third home? You'renliklwy exacerbating inequality every day.

If poor people were more willing to die than to contribute to the same companies and people that fuck them over and the middle class was more willing to work for themselves instead of contributing to greedy corporations all for a mediocre home, then we would have much more equal power structures in this country.

Every single person in this country is responsible for the way it is. Being at the bottom isn't an excuse to fall in line and do exactly what your masters tell you everyday.

It's not really miniaturizing if you're using an emulator is it? And emulator was used for the gameboy color as well.

I was expecting original hardware in a much smaller form factor. Instead this is just an development board and screen in a custom enclosure.

Emulators on small devices isn't that interesting of a feat, IIRC someone ran and old version of MacOS on an Apple Watch when it first came out.
Yes, we do that all the time. I'm not sure why we didn't in this case.
>You are not the customer, you are the product being traded.

Yes and this is fine with me. I don't see why this is such an abhorrent concept. I want something (content) without paying (money) for it. Instead I pay with access to my data and behavior.
>I am toying around with the wacky heresy that Karl Marx (not Lenin) was right. Capitalism will evolve into socialism.

that Marx discovered is that the degree of socialism rises and of capitalism decreases linear with the rise of entropy of ownership distribution. One owner of a factory - full capitalism. Many shareholders without any major concentrated holder - any such BigCo feels very close to socialism (where everybody is nominally an owner of everything) as we experienced back at the USSR.

> fully decentralized, consensus based, anti-fragile, nameless, leaderless, borderless, and viral as hell.

characteristics of high entropy, except for the consensus based and leaderless which are supposed to be an emerging property to manage the target object, yet as history shows delegation emerges to make management tractable in high entropy situations and it results in concentrated management power without corresponding ownership - typical socialism of USSR or BigCo or Federal government managed assets and agencies. Thus such a theory predicts some management "council of BTC Jedi-s" to emerge.

Multispectral imaging reveals unnoticed biblical-period inscription
Mining isn't exactly that centralized and even if it were they'd only really be able to roll back the most recent block. That's nothing like general chargebacks, as it would be one-off thing and only be in effect for 10 minutes, and is heavily disincentivized as it would destroy the reputation of the miner.

The difference with legal contract enforced systems is they aren't. No one is going to build a system that restricts it's owner legally, and furthermore legal rules are leaky abstractions that have workarounds and spotty enforcement.

> Bitcoin is a poor currency and a crazy investment -- but the technology behind it is a real breakthrough.

I feel like that should be the other way around. When all the "blockchain startups" and ICOs blow up, Bitcoin will be left standing. The true innovation behind the "blockchain" was its decentralised consensus mechanism. That mechanism is only secure as long as no single entity controls over 50% of the hash rate. Some of the largest Bitcoin miners have so much hash rate today that they could attack any (SHA-256 based) blockchain but the Bitcoin one.

"The Internet is a poor network and a crazy investment -- but TCP/IP is a real breakthrough."... Sure!

Fiat currency gives you some leeway, but if you start trying to monetize your budget, you are risking run away inflation.
Agree. For one, BTC's decentralized nature makes the ponzi scheme highly resilient and scalable. On top of that, the coolness factor is undeniable.

As the Yale economist Robert J. Shiller puts it "You’re fast. You’re smart. You’ve figured out nobody else understands. You’re with it. And bitcoin has this anti-government, anti-regulation feel. It’s such a wonderful story. If it were only true."[1]

Therefore the bubble will most likely stretch a lot bigger (the current market cap of total crypto is 1-1.5% of US equity) before people get scared. But when they do, the fear will indeed be fueled by negative media coverage which might make the crash swift and brutal.

This article doesn't even touch the worst problem with SO. Code rot.

Answers are typically out of date and no longer good practice. Some claim that the ability to edit answers fixes this, but all it does is subvert the accept/vote functions. You end up with strange "Ship of Theseus" answers where what is written has nothing to do with what was so highly voted, or what solved the original problem.

Where SO goes wrong is that they have tried to create a definitive set of answers in a field where the real answers change yearly, or even monthly.

I mean, are you even following the project? Very, very basic changes like "let's change this parameter from 1 to 2" are incredibly contentious, leading to hard forks and loud debates and furious accusations that people are shills trying to ruin Bitcoin for personal profit.

Yes, and no.

Windows Volume Shadow Copy has the advantage of being integrated with he FS a bit closer. So in Windows VSS can avoid some overhead by skipping the 'copy' part and just allocating a new block and updating the block list for the file.

For the Linux systems we had the requirement to work with all file systems (including FAT). So we could not simply modify the file system to do some fancy accounting when data in the snapshot was about to be nuked. So that resulted in me writing a module that sits between the FS and the real block driver. From there I can delay a write request long enough to ensure I can submit a read request for the same block (and wait for it to be fulfilled) before allowing the write to pass through.

> (Why couldn't you use the existing feature?)
We did on Windows, VSS is used with a bit of fancy stuff added on top.
For Linux there is no VSS equivalent (other than the one I wrote, and maybe something somebody working on a similar product may have written). And even if one did come about (or is and I am just not aware of) it for sure was not available when I started this project.

The "position" might have given them more leverage over his actions: They can control the communications and other actions of an employee, to a significant degree, and as someone investigating the bad behavior, the employee now shares some liability for what Uber does in that regard.
Right, things that enable those currently in power to remain in power they do well. Things that help the average citizen, most definitely not.
