Thanks for for the comment. I'm the author of the article. I'd really appreciate some more specific feedback, particularly the parts that you think are dangerous or "not even wrong."

I'll take a look at the Silver Searcher's code and see what pearls of wisdom I can gain.
But they won't even know where someone is right? Anyway I understand the point which also makes the argument for cryptocurrencies much stronger
How about putting up the money for the entire run to resell it at a markup to all the people who were willing to put 5K down? Surely they can afford more than 35K if they can let 5K sit around for the opportunity to pay another 30K to get the car when it is actually produced?

Would that get me to the front of the line?

Actually if you don't agree with it there is an easy way to show that. Don't pre-order.
Yeah, after reading this again I think you're right.
You know, if you read the article, you will find the author agrees with you.
We do Bitcoin and Blockchain development [1]. Full stack JS and Go. Founded the company a year ago, we're now 17 full time employees, fully bootstrapped. Equity and cash flow with several US based startups. Not to mention that we're now finishing projects international teams located in Switzerland weren't able to pull off.

As a side note, half of the team we replaced in Switzerland were from the ETH and Lausanne. Our interns here get more work done than those guys! It's completely surreal, which is why I felt so strongly about your comment.

I got a US Engineering degree from RIT, when I got back to to Switzerland I couldn't even get responses to waiter jobs, let alone programming. That said, I'm first generation Swiss with a non-Swiss name, they probably didn't even look at my CV.

I know people with similar stories in the industry, most of them in the Ukraine and Thailand actually.

The article's been badly labeled.
That happens for tax evaders?

Yes, because smoking cigarettes or purchasing alcohol is not mandatory. However if you choose to do either, the separate activity of paying taxes on them is.

The only way one can misunderstand this distinction is to believe government is involved in anything by default.
Radar is kind of fun to get into, though 2 Ghz isn't a very good frequency for (through-wall) imaging. http://ocw.mit.edu/resources/res-ll-003-build-a-small-radar-... has some SAR demos, and if you follow to Dr. Charvat's website you can see he made a 10 Ghz system that images through concrete walls very well.
> Lotteries are exempt from the Federal Trade Commission truth-in-advertising laws.

Honestly, this is the biggest case against the lottery, of all the things listed in the article.

I can't remember the last time I saw an ad for the lottery on TV, let alone something as ridiculous as the one from Illinois they show in the article. I wonder how much of the problem would be fixed by fixing this, rather than doing away with state lotteries altogether?

> if state governments are going to continue offering lotteries, they need to be regulated at the federal level and with the same standards as private businesses.

Some states actually have privatized their lotteries. Illinois is one of them, though they're changing that back now.

Ironically, the main "problems" that Illinois and New Jersey have reported with this approach are decreased revenue and sales[0] (ie, the exact things this article is trying to accomplish in the first place). So it seems that privatizing the lottery systems would be another approach.

Ten or fifteen years ago, I spent a few years maintaining a "system" in FoxPro for unix on bastard hardware . . .
I once had to maintain a system using "Westi" 1.1, Westighouse's knockoff of CICS . . . The day I completed my first serious project and linked it, I crashed the company because the operating system was named "test", so I'd just overwritten it. About the time I was fired, I figured out that the entire system was bootleg.

The on disk part of the "switch", our transaction record, can only be accessed internally. There are only a small number of operations to perform on it - create it, read its value, and a small number of deterministic "read-then-write" operations. For example, in the case of an "abandoned" transaction, a later transaction may want to read the abandoned transaction record, see if it is still "pending", and then mark it as "aborted" if it is.

Our runtime orders all such operations on the same record so that they are completely sequential - that is, even for a "read-then-write" operation, it must completely finish before any other operation can occur on that key. This is done using basic runtime synchronization primitives (mutexes, channels, etc).
YES. And to an extent, just punching the clock is a defense mechanism in work environments where low autonomy + high demands are creating an environment for burnout. But I've seen bright-eyed 23-year-old engineers suffer vicious burnout by trying to tackle the low autonomy part ("Hey boss, what if we did X? Hey boss, I put together this slidedeck for this feature that would be so cool! Hey boss, check out this mockup I did of a site redesign!") and then after hitting a brick wall enough times they become embittered and disconnected.

I think it's because equity creates a belief in young workers that the company is "theirs" -- but after you've realized that startups are like any other job where you trade time for money while implementing the Highest Paid Person's Opinion, you lose that passion quickly.
Uber Pool and Lyft Line are already paving the way for car sharing along popular commutes. In the future, you will face the option of a ride home in a self-driving car either alone for $15, or with two other passengers for $5. The decision will be pretty easy for most people.
Deposits are non-transferable. If you want to venture down some whacky scam to get around that, I'm sure you could try.
I'm not sure how one would do a study to test a statement so sweeping. But I was probably too glib in any case.

It would be more accurate to say that the framework within which microeconomic phenomena is pretty well understood. While there's still plenty of room for research to fill out all the details, there's very broad consensus about how the answers tend to look. Concepts like price elasticity are well understood and non-controversial.

That stands in sharp contrast to macroeconomics, where even when talking about the same stuff, say, ZIRP, there's fundamental disagreement about what factors we should be researching. (and when I say "we", I mean people that aren't me, 'cause I'm not an economist)
Not sure who is saying it is the best car ever built.

It's long term reliability has been marked as questionable to say the least and the interior build quality is to put it mildly embarassing. There are budget Hyundais that are more luxurious.
OpenBSD does not run on the rPi because there are only a handful developers taking care of the arm subtree, and none of them have time for it or are simply not interested. Heck, their whole arm subtree has been rotting and needs some major overhaul.

The main components of the new rPi are rather simple to get to work, so it's not a technical issue. The only real crapware inside is the usb controller.

I bet if someone supplied a diff they'd gladly take it. Also, I wonder why this rather old post is up here.

Google's openly stated that they would likely be working with existing car companies as OEMs; Tesla would be an unsurprising choice.

In extreme cases it does. You hear it pop up on the news every once in a while in the US.

It does keep a lot of people from putting their money in with organized crime.
I'm interested in how this could affect other business models that use independent contractors due to less responsibility.

Even more, what are all the benefits a company receives by using independent contractors vs. employees? Does anyone know that can list them? I realized I am not aware, I've been a salaried employee for 15 years.
They do sound a bit contradictory, but I think what is being said is that:

- Rapid growth is a good sign, but not on it's own (i.e. without profit).
- VCs like startups because they show a rapid amount of growth (but the risk is also higher due to a potential lacking model for profit in the startup).
Or Google Now will simply suggest people in your area you could commute with, based on its aggregation of your daily commute data with the data of others, based on the time you leave every day.

Or perhaps Google Maps will do that. It supports Uber internally as a travel option, no? Wouldn't it be interesting if that dropped away and was replaced with Google's self-driving car scheme one night?
That is true. In fact, some people make this argument that people "mooch" off the government by purposefully restricting their income in order to reduce taxes and qualify for welfare programs.
That's what happens to tax evaders who fail to evade enough taxes to pay off the people in charge. It does not apply to entities that are too big to fail and too big to jail.
If anyone want to use it, I've put it out under the MIT License (available now in the updated source).

However I think most people will look at the ideas involved and implement it in there own way as I've made a few assumptions about the structure of the objects being put in the tree.
Point of this article is that state lottery monopolies impose a tax on gambling. You aren't free to participate in a pooled-cash chance game without paying the lottery 'tax'. It's a consumption tax on gambling.

That's probably not a very controversial thing to tax, though.

It's usually penny wise, pound foolish.
You're confusing realism for presence. Realism is not necessary for presence.

I'm using the conventional notion of realism: that set of coventions, idioms, beliefs, habitual expectation that form your set of what is "real". This is easy to test -- if you were to go to another country with a very different culture, some things will jar you out of your expectations. Other things like catastrophic natural disasters tends to shock people into paralysis because the thing going through their mind is "this isn't real". You see a tsunami coming your way, it's real enough, but because you haven't experienced it, you might spent some time wondering if this was "real".

Presence, on the other hand, is the experience of being embodied within a space, whether that space is tangible or not. It is quite possible to have presence within an artificial space whose laws of physics do not resemble anything that you expect. Presence is typically attained when the uncanny valley is crossed. In other words, it's the brain that needs convincing for the presence, not your expectations on what "realism" is.

If you are finding unrealistic elements are jarring, that's more likely that the tech has not crossed the uncanny valley for you. There's a strong case that the current generation of VR tech works well for men, but probably not women, due to physiological differences in neurology.

However, if the VR experience has presence, but things don't operate the way you expect, that leads to a different experience: an existential crises.

I'm looking forward to where this is going. Our civilization needs this tech badly, to help break us out of conventionality and closed-mindedness. Some of the most interesting project includes a VR sim of being in a warzone as a bystander ... to develop empathy for people elsewhere. That's something the current social networks don't foster. We still have difficulty seeing things from someone else's point of view.

If the world wide web brought information closer together, the mainstream adoption of VR can potentially bring people together. And that's a big deal.
But are they written in Go?
I doubt looking and counting under microscope is illegal. Also, not to learn from successful competitor's product would be very foolish.
I'm not saying that state monopolies are good. I'm saying that people need to get over the idea that everything they dislike or disagree with is "a tax". It isn't. A state monopoly on fuel would be almost impossible to avoid, and you could reasonably assert that it's a tax (there would be debate, but your position would be reasonable). After all, even if you don't yourself consume fuel, almost every product you could possibly buy has to be transported from somewhere, and most transportation services available today use fuel. A lottery is nothing like that. The product, such as it is, does not form a component of the cost of any other product. All you have to do to avoid giving the state money is not play the lottery, which should be very easy since they are very up front about the fact that a ticket is not only -ev but much more -ev than any casino or cardroom game you could possibly play. If people stopped playing, the state would either give up its monopoly or (in a classic monopoly-monopsony dynamic) cut its prices. And in the meantime, ex-players would be better off as well.
> Demand for cars is still huge during rush hours. Lots of cars sit idle during low demand times, but that capacity is still needed to meet high demand times.

That's a bit easier to solve. Congestion pricing along with economic incentives to employers who employee remote workers. Traffic is an externality; if you absolutely need workers on site somewhere in a dense urban area, you can do so, but you're going to pay for the privilege of all that infrastructure you're tying up.
"In the last 20 years only 2 new drugs have been approved till a 3rd this spring."

Wrong.

In the first 7 months of 2015 the FDA approved 6 oncological drugs

In 2014 the FDA approved 10 oncological drugs

In 2013 the FDA approved 12 oncological drugs

https://www.centerwatch.com/drug-information/fda-approved-dr...

It is true that only 3 drugs have been approved specifically for neuroblastoma, a rare childhood cancer. This accounts for 6% of childhood cancers.

Misrepresenting facts does nobody any good.
Hi, thanks for the reply!

I will read the more detailed document. It would probably make more sense to me.

From the description of MVCC that you say, it looks like you're storing the whole replicated state machine that you have via the Raft protocol. If txs are assigned such a timestamp, I agree that could operate as a full MVCC system. Good.

Regarding the overlapping txs, it makes sense once you say you're aborting txs. Without that, it sounded really difficult to achieve without locking.

When you say reads only check the switch if there is a write intent, where is exactly that "switch"? I understood it's not with the key, but rather at some other random location. If that's the case, I insist that you require two reads: one for the key, the other one for the switch. Os is the switch co-located with every key?

Regarding the aborted txs, I can't argue without numbers, but I'd like to see those. I mean: you may abort txs voluntarily (I want to ROLLBACK) or involuntary (there's a concurrent conflict). That may or may not be a high number. But all of those would be written to disk, so it might become a high price.

Sargun is correct, all of our replication is performed by Raft, which exists at a lower level than the content covered in this post. Every command executed against a cockroach key (i.e. "create write intent", "begin this transaction") is persisted to the Raft log before executing; Commands will not proceed if they are not confirmed by Raft. The outcome of all commands is deterministic, so this provides complete replication of all mutations to each key.

Remember how computers were supposed to eliminate paper in the office? Now we have more paper than ever thanks to computers.

With self-driving cars people can have their cars out running errands for them during the day. Need to pickup something two hours away? No problem, send your car to get it while you are at work. The car that was sitting idle in the parking lot is now out on the road during the day.

By eliminating the driver the number of cars on the road might increase dramatically.

Abraham Lincoln said this. But you cut him off right before he got to the point!

"Similar too, is the correct reasoning, in regard to the burning of the negro at St. Louis. He had forfeited his life, by the perpetration of an outrageous murder, upon one of the most worthy and respectable citizens of the city; and had not he died as he did, he must have died by the sentence of the law, in a very short time afterwards. As to him alone, it was as well the way it was, as it could otherwise have been.--But the example in either case, was fearful.--When men take it in their heads to day, to hang gamblers, or burn murderers, they should recollect, that, in the confusion usually attending such transactions, they will be as likely to hang or burn some one who is neither a gambler nor a murderer as one who is; and that, acting upon the example they set, the mob of to-morrow, may, and probably will, hang or burn some of them by the very same mistake."

There is a reason the lottery is referred to as a "tax on the stupid".

Software is just one very small part of the work involved in building and selling a car globally. Not sure why you are fixated on it. At this point in time there is no evidence Google has put in the necessary steps to be ready to sell a car in 4 years time. And yes their absymal record on consumer hardware counts.
Heh, somehow putting a gigabyte or even 2 of DRAM on in the CPU package isn't going to threaten the DRAM market. Unlike the static ram market which was decimated by the ability to put more transistors on the die, there is almost an insatiable demand for main memory. One of the things Intel could do which would rock, would be to create an ECC store on die so that any memory you attached could be error protected, giving rise to a core area that is ECC protected and maybe a larger less core area that is not. So in a 128GB system you ECC protect the first 8GB for the OS and programs and leave 120GB of "regular" memory out there for non critical spaces. That would shake things up a bit.
Because all these questions make an enormous difference in determining what your X number will be:

1. If you believe you can live on $5000 a month then you need to know there is $5000 a month available to you. If you believe social security will exist and you believe you will get about $1000 a month from that, then you really only need to come up with $4000.

2. Would you like to have just X in the bank at age 65 or do you prefer to have X + Y, just in case of emergency? If X is your maximum what is your minimum number you would take? That's your risk.

3. Are you looking to travel extensively, buy a nice home on the water, give to your kids, grandkids, etc...? These all again impact X. And while you may not know the answer for certain, you should at least have a general idea of what you would like to do since you are obviously trying to plan for retirement.

4. Simple question, are you going to help your kids with their education or not. Nothing wrong with either answer, but knowing the answer will impact your X number.

So going back to your original question of how much wealth do you need to retire at 65, it really depends on what you plan to do when you turn 65. Do you plan to live in a small home that is paid off or purchase a new home, do you plan to have kids or grandkids, will you drive a car, do you plan on being married, do you want to travel at all, I can go on. The point is there is no single answer to your question. I could probably easily retire with $1M in the bank and never look back. But a friend with 5 kids will probably need a whole lot more.
I wrote this for a small game I'm updating, which has about 30 objects colliding. However in my situation because it has so few objects the overhead is greater than the time saved. This system works really well when there are many objects.

See if you can use a regular quadTree if you can find a way to do it. It'll be faster than this.

I don't know about the _most_ efficient method. That is a field of research bigger than my weekend project.

Good luck.
