> I think people will still want their own personal cars, because...

I'm not making a case people won't have their own cars, I just think it will be less common, and extremely less common to have two or more for a family.

> ..they won't want to get the car with the drunk vomit urine and heavily graffitied and torn up interior.

It's not like you don't know who was in the car that caused the problem, and can't have the whole day recorded for proof. Charge a cleanup fee, include video as proof. If it requires immediate cleaning and must be pulled off the road, charge them for the average income for that time as well. If it's in the agreement for the ride, you can auto charge the account/card as well, since that's how they paid in the first place.

I think that's plenty of incentive to cut down on people not treating your vehicles well because there's no driver to call them out.

> People might also want personal cars as a quicker convenience, and also as a status symbol.

Sure. For the same reason people buy $100k+ cars. That's a somewhat small segment of the market.

> There's also those who might want to ride around in a personalized custom car, much like people do today.

Insurance will likely start to make that expensive. Sure, it will happen, but I think it will be less common. It's already an expensive hobby.
Somewhat unrelated, I'm curious if there are documented examples of raised coin from an ICO being laundered/tumbled.
Yeah, I've read it, I know the definition, and I understand the intention behind adding tests to legacy code. Unfortunately, TDD (meaning TDD as I've encountered it in print and in practice) encourages people to think that "no tests" is tantamount to "no value to preserve" and therefore "no risk of harm from refactoring." Maybe that's an exaggeration, but certainly some TDD practitioners think that they can't possibly harm a codebase by adding tests. Unfortunately, testing requires refactoring, refactoring is redesigning, and if you don't understand the design you're modifying, your changes can make the code less understandable, not more. Tests added after the fact impose the test-writer's understanding of how the system works, which results in chaos if their understanding isn't compatible with the understanding embedded in the existing design.

Also, in spite of that definition, there's a lot more to "legacy" than not having tests. Not having access to the original designer and not having access to the the requirements or domain understanding that influenced development are important handicaps of legacy code that are entirely separate from tests. Certainly tests added during development can capture some of this knowledge, but adding tests after the fact does not automatically recreate it.

These are both examples of the danger of trying to elevate one aspect of software development to a primary and sufficient role. "Take care of X and everything else will work out" has no known solution for software development, and any methodology is harmful to the extent that it encourages people to think that way.
Of course it's not an actual coherent 'strategy' per se. What I was referring to was the openness inherent in western liberalism, which together with its institutions and competitive ideals, has caused it to be adopted and spread throughout much of the world, ie, the rise of the west, since the 1500's.

An example of the first to adopt such ideals, would be Japan.
The law does allow for all of these people serving extra days in confinement to seek financial damages for each day. It seems to me like a civil attorney could file boiler plate lawsuits for each of these people, since the underlying facts in each case are nearly identical. Besides the money that both the attorney and his clients would enjoy, that would be by far the fastest route to getting this fixed. It will stay broken until it hits the county in the wallet.

We are indeed. Out philosophy is that its better for everyone to prevent a claim before it escalates into one. To that end we provide smoke, flood, motion, and door sensors, along with an (optional) camera. We've got some other cool things in the pipeline capable of not only detecting problems but also responding to them before they become a crisis.

You're definitely right that there are privacy issues to be answered but we try to be as transparent as possible about what we're doing with customer's data, and by being stringent about who has access to sensor data.

Yes, logic and reasoning from facts/propositions to conclusions, should be taught to all, IMO - and this applied even before computers were invented. I see a lot of people these days (who are otherwise educated, even) unable to formulate basic logical arguments, and hence either make illogical arguments and deductions, or just go by emotions only, neither of which is good for the world. There is a place for both the head and the heard, and neither should rule.

Like I said, accuracy isn't so much the goal... The readouts I get show pretty consistent measurements over time, which gives me enough confidence to compare them to other Fitbit users among my friends/family as well as to myself over time (see the alcohol anecdote above).

Setting the sensitivity to "normal" just raises the noise floor in their filter so high that it obscures the data.On sensitive, I've never had issues with it identifying "sitting" as "sleeping", yet it still effectively tracks my sleep (including periods of wakefulness immediately pre- and post- slumber in bed as well as mid-night disruptions that wake me up). This suggests that I'm getting pretty good data (though not equivalent to a sleep study with ECG/EKG equipment). In this case, "good" is good enough for my uses.
Interesting. I definitely made this mistake as a child. My dad's cell phone number started was 915-XXXX. I misdialed once and dialed "911".

I explained that it was a mistake, and they said not to worry about it and hung up. No officer was dispatched.

I wonder if something has changed since I made that mistake, if it's just inconsistent across the country, or if there is some discretion of the dispatcher to decide that the child probably did make a mistake.
Similar experience moving to bay area from the UK, where furnished apartments are _far_ more common. I remember expressing surprise at a temporary budget for furniture rental in the moving expenses work covered. Given I didn't want to continue paying Cort a ton of money forever for tables and chairs I chose to buy all my own not particularly great furniture straight off the bat.

I always get horrible flashbacks to my own experiences seeing another "fresh off the boat" foreign engineer trying to outfit his entire life in one trip to the East Palo Alto Ikea, using up an entire roll of receipt paper to cover the hundreds of items they had to buy for their new unfurnished home.

I've done a sleep study at a hospital to see if I was an actual insomniac or had sleep apnea. It turns out I slept like absolute crap at the study mainly because the thing they put up my nose tickled my nose hairs and the thing on my head was uncomfortable, so I just was restless the entire night.
> ICD codes are what's used for public health statistics, whereas CPT codes are used for billing.

Very roughly (it's more complex, but not worth more detail here) ICD-10-CM diagnosis codes are used for billing, and ICD-10-PCS procedure codes are used for institutional billing, as well. HCPCS (which include CPT) procedure codes are used for professional services billing.

We see ourselves as competing more with "ownership" than anything else. To us, ownership of furniture (i.e. responsibility for big ticket items that tie you down) is the problem.

Our competitive advantage to financing options is just that: we remove ownership from the equation while still giving you the ability to pay monthly rather than a large lump sum.

"Even if Emacs on Guile happened, the user would not program in Scheme, but still in Emacs Lisp."

Well, you could program in eLisp, and most people probably would, but you could also program in Scheme. Most emacs programs would remain in eLisp for a long time, though, as it'll take a while to convert them all over to Guile.

So, yes, this is a long-term project, and most people would continue to program in eLisp for the foreseeable future, but some would program in Scheme and try to convert existing eLisp programs to Scheme.

That's my understanding of the situation, anyway.
The reason is that Oprah operates in what's called a "winner take all market". There are thousands of baristas, servers, and (probably) garbage collectors with failed dreams of stardom in Hollywood, etc. But you don't hear about them.

Garbage collecting is not winner take all. No single garbage collector can corner the market because the role doesn't require unique talent in the same way that being a famous talk show host does. Oprah's value is her unique personality, brand, style, mannerisms, business savvy, etc rather than any sort of utility (like removing up your rotting trash) that she may or may not provide.
For me, it was the difference between assumptions/inferences and repeatable measurements... Being typically human, I was able to be unobservant, post-rationalize my poor sleep, believe I still had the drinking constitution of a 20-year-old, and otherwise ignore the effects.

Having months of daily Fitbit records that I could look back on well after I forgot about my "rough morning" the following day drove the point home as only hard data could.

Right, but the difference is that the British have spent the last couple of centuries diminishing the power of the House of Lords, not seeking to aggrandize it.
What's wrong is the absurd fees they charge. The only difference I can see between them and payday lenders is the shabby facade of credibility they think they have by being a "tech" company.

Of course I can't speak to your individual experience. But these are events where a lot of people are in close proximity and hence the chances of meeting others increase.

In music festivals, the last few women that I met were: sitting next to me watching music, in a line to get beer, dancing to my favorite band etc. It seems to me the social norm in the US for the guy to first initiate contact, so you've gotta be able to do that. Women generally have never initiated conversation, except the most extroverted ones.

I like Art Shows/Museums better because they tend to attract a little more educated/sophisticated crowd. I mean, to be fair, I don't go to these places with the explicit intent of meeting women, but the last time I was in MOMA in Houston and there was a group of ladies talking about Napoleon and I couldn't resist asking questions... it was a great conversation and sharing of minds!

Need for Speed: Web Performance Optimization of Alexa Top 25
Having spent 7 years of my life working with Pat Helland in implementing Exactly Once In Order messaging with SQL Server Service Broker[0] I can assure you that practical EOIO messaging is possible, exists, and works as advertised. Delivering data EOIO is not rocket science, TCP has been doing it for decades. Extending the TCP paradigms (basically retries and acks) to messaging is not hard if you buy into transacted persisted storage (= a database) for keeping undelivered messages (transmission queue) and storing received messages before application consumption (destination queue). Just ack after you commit locally.

We've been doing this in 2005 at +10k msgs/sec (1k payload), durable, transacted, fully encrypted, with no two phase commit, supporting long disconnects (I know for documented cases conversations that resumed and continued after +40 days of partner network disconnect).

Running into resource limits (basically out of disk space) is something the database community knows how to monitor, detect and prevent for decades now.

I really don't get why so many articles, blogs and comments claim this is not working or impossible or even hard. My team shipped this +12 years ago, is used by major deployments, technology is proven and little changed in the original protocol.

> Does policing and maintaining vacant lots actually incur any meaningful costs on a city?

Vacant, unmaintained lands tend to attract crime. I say this from first hand experience- I was a teenager once, and we went to vacant, unmaintained land to commit crimes. We were good kids, mostly, but we weren't the only ones there.

> by providing habitat for predators of urban wildlife, dense plant growth to improve air quality and soak up stormwater, etc.?

I'm all for having dense forests near high rises (more birds! more plants! yes!) but that land is expensive to buy, expensive to maintain, expensive in terms of lost tax revenue.

I simply argue that someone has to pay those costs, and getting mad at the city of being fiscally tight when politicians are elected promising exactly that is silly. You want to have a park/forest/whatever? Fine, but acknowledge that it's expensive and then pay your fair share of it.

Similarly, the editorial board of the Journal of Algorithms stepped down in unison and started the ACM Transactions on Algorithms, in protest against Elsevier, back in 2003.

Don Knuth, founder of the JoA, had a hand in it. Wish this happened even more often - without the scientists (and the prestige/impact factor endowed by the scientific community), the publishers have nothing. Don Knuth's letter (typeset in TeX, of course) is well worth a read [1], and since then the situation has only gotten worse, I think.

> Is a company that badly off if they need to write down the cost of a building if it gets burned down?

That means a company has to always keep cash in reserve against the off-chance of its building burning down just because insurance can't be trusted. That's money that can't go into expanding the business and creating additional jobs. Imagine the overhead of this parked money across thousands of businesses. Not to mention a lot of startups or young businesses can't have that sort of cash position, which means it becomes another barrier to starting businesses. It would be a major impediment to the economy.
When I was a newbie, I would often say things like "maybe the compiler is broken" or "maybe the cpu is doing it wrong."

Of course, it was never the tools. it was always me.

Years later, of course, I work on unreleased hardware. And yeah, sometimes it's broken. It's really fucking odd. Write C code, and holy shit, it's actually a compiler bug or CPU bug.

Life was simpler when I was just ignorant and egotistical. Now I'm... well, still ignorant and egotistical, I guess, but often deal with actual hardware bugs.

I mentioned this in the last thread about Hong Kong, but they're not as dumb as you think. Taiwan (both the Blue and Green coalitions) has always distrusted "one country, two systems", even way back in the 90s before Hong Kong's autonomy started getting salami-sliced away. China knows that, and knows they're not really losing anything by abandoning that approach.

That's not their plan anyway. The parallel tracks for dealing with Taiwan are

1) building ever-closer economic dependency, and then punishing Taiwan every time it elects pro-independence leaders, so that Taiwan has no choice but to elect pro-reunification candidates for the sake of economic security and

2) gradually muscling the US out of the region and building naval capabilities so that if 1) doesn't work out, they can take it back by force.

How Taiwan feels about "one country two systems" doesn't really matter to China.

> 1. If one of the two containers caused the issue, then the why you needed both of the containers to produce the issue? Why running just the offending one was not enough?

Running just the offending one would have been clearly enough, since its effects would have caused the same increased latency for every other process in the system (including itself). However, using a second container to observe the performance degradation proves the point that one container is able to affect another one, which is sort of the gist of the article, since too many people think containers provide much more isolation than what in reality happens.

> My guess is that "worker" container requested those non-existent files from a volume mounted by the other container, is it right?

No, the containers didn't share any volume, the dentry cache is effectively a singleton within the kernel, so even if the set of volumes is not overlapping, all processes in the system will see a performance degradation, regardless of where the files being accessed reside.

> 2. Kernel hash table implementation. The whole point of hash table is that it's size is O(N), where N is the number of elements it holds.

Your speculation is correct, however, there are sound reasons for doing such a thing in the kernel (and not allowing the main array of the hash table dynamically expand/shrink), so I wouldn't consider it a bug per se.
