"Exactly Once"

Over a window of time that changes depending on the amount of ingested events.

Basically, they read from a kafka stream and have a deduplication layer in rocks db that produces to another kafka stream. They process about 2.2 billion events through it per day.

While this will reduce duplicates and get closer to Exactly Once (helping reduce the two generals problem on incoming requests and potentially work inside their data center), they still have to face the same problem again when they push data out to their partners. Some packet loss, and they will be sending out duplicate to the partner.

Not to downplay what they have done as we are doing a similar thing near our exit nodes to do our best to prevent duplicate events making it out of our system.
Even with a line item precoded estimate, it would require some negotiation between what the doctor/lab thinks it costs versus what the insurance thinks.

Doctors/Labs are often surprised after the fact by what the insurance company allows, thinks is miscoded, will pay, etc.
Home Delivery? What Will They Think of Next?
its a PR ploy to sell data to corporations.
This article desperately tries to pin the thought leader phenomenon on billionaires, but I don't buy it. Billionaires are certainly susceptible, but plenty of poor people believe this stuff too. The article even tries to cleanly separate academia from TED talks et. al., but I know plenty of people who came out of their masters / PhD spouting stuff like this.
You would have to hack the upnp device's firmware, afaict.
The article spends many paragraphs on the complexities of the B2B and B2C players in insurance, their distribution channels, and how they get paid. It spends one sentence on noting how the pricing of risk is based on actuarial models, and then moves on. The pricing of risk is absolutely key to the entire industry, and it is stone age! It's all done in spreadsheets.
That's makes it closer, but still not a slam dunk, which for me a service like this should be. Eg, $35 / mo for a couch including drop off and pick up (which it looks like they do) makes renting very attractive.

EDIT: looks like there are delivery and pickup fees, actually. I'd like to see those included in the price for rental periods of, say, X months or more where ideally X would 6 but 12 is probably fine.
How Often Do Customers Pay Different Prices for the Same Thing?
I think anyone who has been single long enough to experience the soul-draining tedious world of modern dating could understand and appreciate a way to optimize any part of matchmaking.

Also, I think "speed dating" is just a less geeky version of this.
TDD failed for economic reasons, not engineering ones.

And yet, engineering is inseparable from economics.

Thanks that's I interesting. A manager pushing some odd agenda w/o much reason is expected; but if you respect him/her and observe a few other signs then it might be a life boat in disguise.
Everybody knows "exactly once" means deduplication. This is not exactly a new problem.

That said it's still a difficult problem and I actually wish people would stop trying to roll their own schemes. For example, this scheme relies on examining a Kafka outbound topic to resolve in-doubt outbound messages. But what happens if the outbound message + commit is still "in flight" when the system recovers so the system retransmits the in-doubt outbound message and so rather than deduping it now is generating dupes? Yes, the chances of this are minimal which means it will happen.
You're exactly right. There are a number of other costs associated with getting the furniture, assembly, and selling or scrapping costs that are sometimes difficult to quantify.

Wondering how y'all think we should be communicating this to our customers? Thanks!
That should come as a hint that state actors are not the only ones capable of deploying informational weapons.
Math and CS coursework should probably be married at these levels.
It's funny that you say that, because I've been getting into ES6/TS lately (mostly to implement my own stuff) and that's basically been my reaction: "this stuff is pretty straightforward, why is so much code so bad?". Then I realize that I've had to understand, if not implement, those web technologies to do the work I've already been doing (and, years back, I wrote a JavaScript runtime as an experiment, so the language's guts aren't foreign), and I'm just picking up the other end of the rope now.

The amount of implicitly-carried junk we all know about to be good at our jobs instead of just tolerable is pretty amazing.
I agree with your assessment that one minimal is fundamentally better than a another newer one. I fail to see how replacing windows XP with a minimal can do anything other than result in an improvement.
Also, HTTP/2 can reuse the same TCP connection for multiple domains with SAN
I wouldn't worry about losing your job. Software engineers will always be in demand, and demand will only increase.

I pretty much do the same job that I did in 1994. Only then, I made 1/5th as much and had 5-times as many people on my team. But, back then, few people wanted to do this type of work.

When software engineering salaries go back to normal (i.e. when they don't encroach on the 'leadership class'), it will be fine. Probably more fun, too (for people like me at least).
> Do you think it is impossible for #2 to exist?

not the OP but, in the long term, yes, I do believe a for profit entity is at odds with that. Shareholders clamor for more profit and will not be content with no growth.
This is really cool. What happens when multiple people try to call you at the same time?
Sounds like that netsec guy's team serves military customers then?
Piecework is not illegal in the US. They may structure it in a particular manner so that it uses a loop hole in the law but I know of a number of companies that pay by the piece.
This might sound ridiculous, but the web isn't going away. Read this document and practice the concepts it teaches well: http://prettydiff.com/guide/unrelated_dom.xhtml

You can practice this directly in your web browser (developer tool's console) without any additional code editor. I am teaching my wife this now. If you can master that one skill and slowly build up some JavaScript confidence you can always find a job... so long as web browsers are a thing.
No, because most people are still not going to have the natural talent to be programmers.
I would consider our transmission of electrical energy to be very efficient. To transmit power thousands of miles and only lose a few percent is remarkable.

I know of at least one company (https://www.rentacenter.com/) that does furniture and appliances too. Same basic pitch: we deliver and set up, you can upgrade or stop renting at any time.

I don't know why you're getting downvoted, but for there being a lot of money to be made by not understanding where commercial surveillance is ultimately headed.

The threat of government surveillance pales in comparison to the means of control that "private" industry will eventually "innovate" for the goal of "reducing risk". Drinks at dinner in the middle of the week, paid for with your surveillance card -> higher auto insurance. Not enough physical activity recorded on your wrist/chest surveillance device -> higher health "insurance". Fixing something around your house instead of hiring a manufacturer approved service company -> higher homeowners insurance. Taking a job with a startup instead of sticking with your predictable job at bigco -> higher mortgage insurance.

Which could be fine if such risks were priced accurately, but the centralizers' prescriptive models of the world can never actually capture reality (eg the difference between a qualified/uncredentialed repairman and a credentialed/unqualified one). Instead, it will mainly be used for price discrimination to gouge those who'd like to deviate. As more people fall into line (eg sign up for the current ruse of adding a driving surveillance device to save on auto insurance), the ability to even opt out of the surveillance ("no signal") will vanish!

Throw in the fact that many insurances are de facto or even de jure mandatory, and we've bootstrapped a system of mandatory restrictions (ie "laws") which are not even token-responsive to the governed. And similar to all teeth of the totalitarian ratchet, such developments will be cheered on by moralizing useful idiots gleeful that the "other" will get their comeuppance - blissfully ignorant that after the initial discount period, their rates will go right back up.
> The last point I'll make is that everyone gets older eventually. Higher premiums when you're younger are a form of pre-payment for the care that will absolutely be required when you age. Unless the government forces people to pay these premiums the most rational thing for any individual actor to do is cheat and skip paying premiums when young, then force the cost on others by buying in when you're old. It becomes a classic tragedy of the commons situation where only sick people buy policies, resulting in massive losses and sky-high premiums no one can afford to pay.

This is not true. People die young, some die quickly when older, with few health costs, others linger with huge costs. I can see an appropriate insurance product that protects against the risk of those varying outcomes.
That's what I'm currently doing with the tablet and the vertical mouse. I have the tablet on my left side the mouse on my right and then it's just a matter of remembering to not use my trackpad :-)
And even if you were 100% driven to teach, you could be consulting for a code school or something else thats far more lucrative. I'd consider at this point the only people who are actually teaching full time would be people doing it for charity. Except, instead of being thanked you have to navigate all the administration and just plain pains in the ass that come from being a teacher.

The most likely people to go teach how to code are:

1) People who are only academic and don't have any desire to join the private sector (unlikely to be the best teachers)

2) People who've joined the private sector and have their retirement already done (unlikely to put up with administration)

3) People who code as a hobby, have a spouse or other financial support (hard to find at all)
Thanks for trying it out. If multiple people call you, for the caller will just hear the busy tone. In the future we plan on adding multi-call/routing support.

As I remember, one Microsoft was one of the original TDD pushers.

You may be mistaken: There was a well-known incident back in 2005 where Microsoft published guidance for TDD that was flat-out wrong (or at least not fitting with the mainstream understanding), and they had to retract it (in fact it was so far-out that they had to expunge the article from MSDN).

http://codebetter.com/jeremymiller/2005/11/18/microsoft’s-re...

One person who worked there for over 20 years told me that "the peak TDD" at Microsoft was right around time of Win ME release

Of course, Microsoft is big, and the broken guidance may not have reflected practices elsewhere in the company, but it seems unlikely that they were early TDD pushers if they hadn't grasped the concept (as commonly understood) by 2005.
IPv4 addresses are relatively expensive. I encounter it quite often where a wildcard gets pointed to a single server (with single IP) which hosts multiple services. There are no security issues compared to a large SAN that I can see in such a situation.
The biggest thing I can say is don't underestimate underwriting. There's a reason a lot of carriers focus on specific areas. There's a hidden customer acquisition cost in that a group of new customers that has a bunch of bad business that needs to be weeded out.

If you think about it a customer knows their own risk better than anyone. So, you're betting that you can judge their risk better than them and your competitors over and above your cost to manage paperwork, regulations, money and fraud.
After fooling around with porting some Common Lisp code to Python as an exercise in reinforcing my understanding of the underlying algorithms and learning Python, I would describe the difference as the Python interpreter was mostly designed with the assumption that the typical use case would be executing the interpreter with a source file as an argument [e.g. python spam.py] and not primarily as an interactive development tool that is left as a running process for days or weeks. Instead Python ships with IDLE which more reflects the idea of an interpreter running source files serially.

Or to put it another way, trace is an option that is passed to the Python interpreter. In Common Lisp (trace ...) is a function that can be called in the REPL.
So basically divide the city by income bracket?
> when the most likable people come into your life when you least expect it.

There is often truth to that, but you have to put yourself into scenarios where that is more likely to happen. Be social, meet as many people as possible, etc.
> Dude, they love their government with extreme pride

I'm going to present as much evidence as you have - none - but in my experience this is categorically and absurdly untrue. And your claim that others don't see this because they're "obvious American" is the opposite of reality. The only times I have seen Chinese express "love" for their government is when it's criticised by a foreigner. Between themselves they complain non stop. The best the CCP can hope for from the vast majority of its populace is, as far as I can see, a kind of grudging respect.

You really need to learn the difference between extreme pride in your country and in your government, because they are two very different things. Plenty of peoples have the former - including the Chinese and indeed Americans. I struggle to think of any large population of the latter and they certainly do not live in China.
I was taught VB programming in high school by a teacher that never coded in her life. We just followed the modules in the book and the class would band together to solve the problems of individual students.

Yeah, it wasn't optimal, but we managed to learn to program and several of us went on to be professional programmers. More than one did so right out of high school.
As the Internet-of-Things keep expanding, the need for interoperability and sharing of resources become a necessity. IOTA enables companies to explore new business-2-business models by making every technological resource a potential service to be traded on an open market in real time, with no fees.

As a sometime digital nomad, this appeals to me in particular after Brexit. With the way the pound is yo-yoing and the likelihood of increased friction of doing business in Europe if you're a UK citizen, this seems like a good move.
> Investors treat Tesla like a tech company in their valuation, not like an automaker.

Uh, because they are a tech company. They also produce batteries and solar panels, not to mention making huge strides in self-driving capabilities.

Again, with the negative P/E, keep in mind that once the 400,000 Model 3 reservations start going out the door in a couple months and people need to start throwing the remaining $34,000 at them, that's going to increase their earnings by at least $13.6 billion. That's billion with a B. What will that do to their P/E? And that's assuming everyone gets the base model, which certainly won't be the case. Elon has stated he expects the average car to sell for about $43,000 with options, which would put those earnings to $16.8 billion.

Certainly, there is risk, but their high valuation suggests that investors are confident in Telsa's ability to produce. I'd certainly be buying TSLA if I had enough income to make a worthwhile investment.
I think the answer is to take a hybrid approach. Use an ORM where it makes sense. You shouldn't need to write SQL to do simple CRUD and elementary queries with a join or two. But when things get more complex, you should be able to easily drop to SQL, and have the results mapped back to an object. Perhaps also a DSL that allows you to write queries in code. I have yet to find an ORM that can elegantly accomplish this, although SQLAlchemy comes close.

Some nation-tribes are better at governance than others. Their countries might be objectively better if they were administered by another nation-tribe, but then it wouldn't be their country.

Rhodesia was certainly a better international trading partner than Zimbabwe is now, but at least Zimbabwe is unequivocally owned by the Zimbabweans. Other countries don't exist solely for the benefit of their international trade partners.
I don't follow. I wasn't suggesting that Uber would be forced to tie into such a service, only that this would eliminate their advantage in that respect.

Car and homeowner's insurance only works /because/ insurers have imperfect data /and/ because purchasing it is mandatory in most cases

This is not true and represents a misunderstanding of the purpose of insurance. Insurance exists to protect against large downside risks.

There is, let's say, a 1% chance that my apartment burns down next year and I lose $50,000 worth of stuff. I would much rather pay $500 to insure against this loss than run the risk. I can easily afford to pay the small insurance premium whether there is a fire or not, but a fire would put a very serious strain on my finances that I am very happy to avoid.
> the legislation addresses both the flight restrictions and the noise rule

Noise rules are there for good reason (nobody likes broken windows)... and I'm sure there's military applications for quieter supersonic engines, but we don't have any (either because we haven't tried, or, more likely, because it can't be).

I suppose I'm just highly skeptical they can do both, or either, in reality. Sort of, having their cake and eating it too.

I'd love to be proved wrong here though, so I guess we'll have to wait and see.
Shouldn't we expect plenty of revenue growth since the efficiency edge over competitors means they can charge lower prices? 10% of a growing revenue stream looks like a recipe for pretty happy shareholders.
Re the comments on Data in this piece: Yes, insurance is an industry suffering from perpetual information overload. I worked at a large insurance company for 5.25 years. I processed claims and we relied heavily on systems for looking up endless information. They would totally overhaul the system for doing that every few years. I think it occurred two or three times in the time I was there and I heard from other people that, yes, this seemed to happen every two to three years. It had all kinds of problems. What was supposed to be a new and improved, more user-friendly system meant that all the old timers who had figured out how to find everything were now lost, even with training. It also meant that some things were not compatible and not findable anymore. It was truly bad.

I have a certificate in GIS. As a claims processor, I worked with multiple databases all day long. This included such things as looking up names and addresses for providers (doctors, hospitals, etc -- the people providing medical care). I suggested we create a GIS based system to make this easier. The idea did not fly.

But if you want an area of opportunity in insurance tech, try finding solutions to some of their back end problems. Managing information overload is a serious and ongoing problem in the insurance world. I was there 5.25 years and I only know a thimbleful of information about the industry. Laws and regulations vary by state. In order to sell in all 50 states, you need to get licensed in every state individually and we had to be able to look up "state exceptions" which were laws that impacted how claims were paid in each state and on and on.

People in insurance are absolutely not stupid. It is just overwhelmingly complicated and no one can keep up with all of it. And, yes, it is very fragmented. But if you want a good business opportunity in this space, consider trying to build back end solutions to help them better manage the information in which insurance companies are simply drowning.
But *.a.com doesn't cover a.com, so it's not very clear that the inverse ownership relationship should hold. Yes, it's true on a DNS level but that's one argument I would imagine against doing it that way.
