Classic case of first mover disadvantage. Their failures helped Boeing learn some tough lessons about metal stress, and Boeing got many aspects of the fuselage of their first jet liner so right they're still used on the latest generation of the 737 which will finish in the top two biggest selling aircraft this year. Of course, us Brits learned tough lessons of a different kind with the Concorde: no matter how brilliant the engineering is, you need a mass market to break even on an aerospace programme.

That's a very good point. I suspect it will depend a lot on what the largest PG users contribute back, in order to make it scale.

For MySQL, the largest users were (and still are) the biggest drivers of scalability-related features... and that's despite MySQL being far less of a community-driven open source effort than PG.

From my perspective, the biggest roadblocks for PG adoption at high-volume OLTP use-cases are its historical weakness in replication options, its process-per-conn model, and its lack of clustered index support.

PG replication is improving at a great rate, especially with the addition of logical replication, but the overall spread of options is still behind MySQL (re: multiple kinds of logical replication; multiple options for async vs semi-sync vs sync replication; large ecosystem of tools to interact with the replication stream).

The other two issues are a bit more fundamental. But given the number of excellent engineers working on PG, I'm sure that solutions will be developed in the near future.

Obviously there is a lot of verified intelligent behavior on neural level we know about, like image processing, 3D reconstruction & mapping, motion planning, sound recognition, voice synthesis etc. And we more-less have some simplified models like that in the form of deep learning. So imagine brain as a sensor processing engine for inputs happening in the vicinity of a person inside "Simuverse". Even computing possible actions to take and attaching some utility value of each of them or starting upon acting on the best solution found so far already. Now for the decision process to be complete, brain passes results of this computation to the API that then invokes consciousness in the "soulspace" which is of another yet unknown quality, making the decision ;-) There is some interface latency of course, so some default actions are needed by brain, but consciousness can override them within 0.5s. Brain could be seen as an equivalent of cyberspace, consciousness might be coming from another principle we aren't aware of or don't have proper scientific devices to measure yet (if that is even possible).

Remember, each age views humans differently. Previous civilizations viewed humans first as based on magic, then hydraulics, then mechanics, then electricity, now we view them via lens of information processing, as our Zeitgeist dictates. It's likely people in 100 years will be laughing at us and our stupidity (hopefully they will be more advanced and not in a dark age), after they crack more things about Universe.

Obviously, this doesn't explain phenomena like brain exhibiting multiple different persons inside for patients with schizophrenia or when connection between left and right hemisphere is broken - some experiments shown people behave like as if there were multiple persons inside fighting with each other. Perhaps a bug in the nexus when there is a hash collision somewhere? 8-)

Nothing about this setup feels lean. Why did they build their own feed technology instead of using an open source or hosted solution?

Why did they use Lambda for everything, and invest a crazy amount of effort into making it work well? Their job was to prove their ability to acquire users, they didn't need to innovate on the tech side by using Lambda for everything.

Interviews happen at scale, dating doesn't. Once you find someone, the getting-to-know-you period before marriage is months / years of one-on-one time where you really can get to know them.

It's not the unstructuredness or the judging humans part that's the problem, it's the fact that this is all done at scale by people with more important things to be doing.

If companies all did like Apple in the early days and treated every hire as a bet-the-company decision, bad hires would go away.
Well, Oxygene reached number two in the UK album charts and Oxygene IV was a hit single reaching number 4 in the UK singles charts. Those were popular music charts, and back then there was a much wider variety of genres of music occupying the top 40's, especially in the UK. I was ~11 years old and for a while you couldn't avoid Jarre on the radio and Top of The Pops.

I believe this can also be a problem for US citizen's coming over. If you don't unlock your phone they might take it and/or delay your entry with questioning.

This border/airport security is just like the old fashioned Soviet/German stereotypical scenes. The problem is that propaganda about 'Muslim terrorists' is so effective people think that's what its about. All of that is a lie. This is about restricting freedoms in order to close down a country.

The answer is don't come to the US if you value privacy (i.e. are human).

The United States is becoming a repressive regime. Many people who have the means to do so are emigrating while it is still feasible.
What is 'success'?

My evidence is anecdotal, but I've spoken with multiple Indian women who are in arranged marriages, have zero real love in the relationship, and aren't particularly happy, but the idea of divorce is entirely unthinkable to them. The lack of divorce probably makes this a 'success' by most metrics, but doesn't seem particularly successful to me.

Relatively few, but they're everywhere -- Auto-pilot on airplanes. ABS brakes. Self-driving cars.

"Releasing early", in the sense of getting these things into the real world as early as possible so they can be iterated on with real-world data is actually pretty crucial if you think about it.

Before self-driving cars hit public urban areas, self-driving trucks have been working on private mining roads (https://qz.com/874589/rio-tinto-is-using-self-driving-416-to...). Auto-pilot on airplanes can still today be turned off or on as desired.

The key here is figuring out how to release gently. The greater the risk, the more iteratively and more gently you should be releasing. If you were building landing gear controllers for passenger planes and your plan for release was to spend a really long time planning really carefully, testing like crazy in non-real-world conditions and finally doing a world-wide, all-commercial flight roll-out at once, I'm likely to pass on air travel for a while (and keep a lookout overhead).

When people talk about releasing early, they're not talking about big bang releases at all. There are alphas, betas, feature toggles, a/b tests, and dark paths for a reason.
Much of the equipment consists of analog modular synths.

If that intrigues you, definitely check out the recent documentary on the topic "I Dream of Wires" (http://www.idreamofwires.org/). It is on Netflix streaming, but there's also an extended version that is a bit more geeky. The documentary does a great job of covering synthesizers from the Moog days to the present revival of analog synths. Interesting stuff.

Another problem with ASICBOOST is that it incentivizes a miner to try to partition the network such that the orphan rate increases, because mining on top of orphan blocks is more profitable.

If we have two competing successors (S_1 and S_2) to a Block B, an ASICBOOST miner can mine both simultaneously by creating Chunk 1's with different parent blocks.

I call it "The Oliver Twist Attack".

Increasing the Oprhan rate is incredibly costly to affected miners, this has the effect of making it also increase the hash rate of the attacker.
The good of the individual and the good of the whole are not always in conflict. But these discussions where people try to say that someone with a known genetic disorder should not be allowed to do anything like this so that they can both have a baby and try to somehow give the baby a better outcome always smack of Arian Race bullshit to me.

I did not know I had a genetic disorder when I had kids, so I never had to wrestle with such questions. But I have seen other parents wrestle with them.

The bullshit statements you see about concerns that this child will be permanently fucked up for life are just prejudice. Every pregnancy comes with that risk. In fact, I have read that up to half of all pregnancies miscarry before the woman knows she is pregnant and the theory is these are genetic monsters so screwed up they aren't viable.

Elsewhere in this discussion someone rebutted something I said with something like "what if the child lives to age 53 but is in agony and a burden to society?" I have paid accident claims. To my horror, I have read reports of children maimed for life because of parents being, imo, inadequately attentive to safety. So, a child can be born with no genetic defect and end up missing a leg, blind or paralyzed due to parental neglect.

You are telling me that parents with "the wrong genes" should be wholesale denied reproductive rights because their kids might suffer, but assholes with no sense can have all the damn kids they like because what fucks over their kids permanently is not part of their DNA. And my feeling on that is [redacted, because it no doubt breaks the guidelines].

> Admissions officers look for born-geniuses that can effortlessly get perfect scores.

Meh... I hear this a lot. This is a gross over-characterization of the reality. There are plenty of true geniuses with high grades and high SAT scores who do not get into elite schools. The applicants need something else.

> Thanks for sharing and I've heard this to be case from multiple sources as well, which means, it can also be gamed.

This is a half-truth.

A mediocre applicant will have nothing to show from their experiences, and their recommendation from a person in that field will probably be something like "applicant is nice, shows up, and tries hard". A strong applicant will have something like a publication or a documented initiative that they led, and their recommendation will be something like "applicant did things that went above and beyond what many of our regular employees do -- I don't want this applicant to leave for school because we will be a worse place without them" (with believable detailed examples). Even that will be gamed, and sometimes it is, but there will usually be gaps in the narrative unless there is a decent-sized group of people who are colluding together.

Whenever someone thinks that there is a new formula for getting into elite schools, they don't realize that the key ingredients are things like creativity, curiosity, and leadership. These are ridiculously hard to fake in a compelling manner.
Ah but they wouldn't be 'tourists'.
Is that actually a majority of jobs at Google? I know something about the work that several of my friends working as SREs and SWEs do and it doesn't sound like it involves a lot of distributed systems programming.

Let's say you work on some part of Android. Obviously you need to interact with things like Google's build system which are distributed, but are you really implementing some distributed computation in the course of your every week, or even every month?

I get that Google wants to test during the interview for suitability over a large space of possible specific roles, but I seriously doubt that "distributed systems stuff" would be in the list of top 10 programmer domain knowledges that are useful in those roles. Is it more useful than knowing how to work with version control well? Everyone at Google has to do that, but they don't test it during the interview. Is it more useful than being able to read and write idiomatic and readable Java? They don't really substantially test that during the interview either.

(On the other hand, the things that spawned this conversation were "dynamic programming, parallelism, and networking" and the latter two are much more obviously generally important things.)
Odd - I was trained to do competence based interviews 20 years ago, apparently this is now rediscovered knowledge or something!

> Boeing solved the problem by using rounded windows, and riveting on a forged doubler around the window frame.

Boeing was by no means the first to use radiused windows in pressurised airliners; the Avro Tudor was doing so in 1946 and there may well have been earlier examples.

Conversely the Boeing Stratoliner was flying with square windows in the early 1940s and didn't suffer fatigue failures, nor did the later DC-6. Corner stresses were understood at the time.

What really undid the Comet was that the fuselage skin gauge was insufficient to accommodate the increased rate of change of pressure differential that was introduced with jet flight. Whereas the preceding piston-engined airliners were lucky to hit 1000 feet per minute climbing to 20,000 ft, the Comet climbed at three times that rate to 35,000 ft +.

The Comet had skin reinforced to 20 swg along the window belt, whereas the succeeding Comet IV had 18 swg with 16 swg framing.

Just to point out that SegWit is everything but "already adopted in the industry". It turns out that SegWit is the solution promoted by the developers of bitcoin core to allow for bigger blocks, and solve some issues like transactions maleability. It's more than 10 000 lines of code highly controversial because they require... A soft fork, and will change bitcoin in a fundamental ways.

Not to add that a company called "Blockstream" have paid almost every developers of bitcoin core to push Segwit without a clear consensus from the community. Worse, this company actually support the huge censorship happening in bitcointalk and r/bitcoin. Blockstream received more than 75 millions from AXA, for obscure reasons.

The paper only focus on Segwit, without mentioning that Segwit has nothing to do with ASICBOOST. The community and a growing majority of miners is actually switching to bitcoin unlimited, a fork of bitcoin core.

Sorry for the little off topic comment but I love Bitcoin and I hate that a few dishonest people took control of it and try to destroy it.

All the talk here and everywhere have convinced me that:

- MySql is the choice for niche workloads and to be used by experts not only in DB but in MySql Quirks.

- PG is the sane choice for everyone. Experts benefit more, but inexperienced developers will be better served from a more solid foundation, and still PG is so good that will be along your side for years to come.

PG maybe will not shine in some niche workloads but we are talking about problems that most DO NOT HAVE.

---

Years before, I have read (and believed!) that "PHP, MySql, JS" was "better" for inexperienced (or new) developers, because are more "easy" to learn and use.

Then eventually is show how facebook and others used them.

However, after +18 years on the field, I become more and more convinced that is totally the reverse:

- PHP, JS, MySql, etc are tools for experts.

- More strict tools are better for everyone.

- Only expert will use correctly any tool, even if have quirks.

- This is even more notorious if the tool is more dynamic than static, or provide more "freedom"/less "safety", like C VS. Pascal.

- More well designed or strict tools provide equal benefits to experts, but sometimes a tool with not safety-protection allow to do hacky things easier (or possible).
I find it quite problematic that researchers get to talk about their own research and present it as facts without anyone taking a critical look.

Over time I’ve become more skeptical about this kind of psychology research (as more studies fail to replicate) and, as is often the case, here the sample size is quite small (76 students, split across 3 groups), predicting something relatively noisy as GPA. It is unclear to me that one would be able to detect reasonable effects.

Furthermore, some claims that make it into the piece are at odds with the data:

> Strikingly, not one interviewer reported noticing that he or she was conducting a random interview. More striking still, the students who conducted random interviews rated the degree to which they “got to know” the interviewee slightly higher on average than those who conducted honest interviews.

While Table 3 in the paper shows that there is no statistical evidence for this claim as the effects are swamped by the variance.

My point is not that this article is wrong; verifying/debunking the claims would take much more time than my quick glance. But that ought to be the responsibility of the newspaper, and not individual readers.

Politicians don’t get to write about the successes of their own policies. While there is a difference between researchers and politicians, I think we ought to be a bit more critical.
Could this cut down on sweeteners?

CIA is primarily HUMINT (and intel triage, covert operations, etc) so their focus is going to be on the end points for individual targets. SIGINT is a gigantic field and a shift like this would essentially just a merger of NSA's SID into CIA while leaving NSA with just IAD.

Genuinely curious, what would be the gain in doing that?

Candidates do real tasks alongside the people they would actually be working with if they had the job.
