In some cases that's probably true. But consider how few resources were devoted to Openssl before they ended up in the limelight.
The benchmarks establish a high-water mark and establish the magnitude of performance. Specific rank ordering is mostly a trivial matter, if admittedly a point of potentially fun competition.

Some laser-focus on the plaintext benchmark in particular, presumably because it's the easiest to implement and the delightfully high numbers in the results are exciting. But more interesting are the test types that involve round-trips to the database, using an ORM (or similar), and other framework features. For me, the Fortunes test is the most interesting.

Yes, it's "easy" to climb up a few positions and jockey for specific rank order against other similar contenders, but considering specific rank ordering is not a useful way to interpret the results. More useful is to see the orders of magnitude conveyed by the results. And it is not so easy for a low-performance platform (e.g., Ruby) to game its way into the top positions. See, for example, Java, Rust, and Ruby on the Fortunes test:

Obviously, no small benchmark can measure the performance characteristics of your application as implemented on multiple frameworks. But these are a proxy, and illustrate the performance landscape your application will exist within. They can reveal the bottlenecks your application will be unable to avoid in framework services such as JSON serialization, object-relational conversion, connection pooling, server-side templates, and so on.
I'm unsure why this is being downvoted. I think it's a completely fair assessment given what happened with Hubble. At that time we had the Shuttle to head up and actually fix things that were broken. I have doubts that SLS is going to be as quick as they want it to be, and crewed Dragon isn't operational yet either. By the time this thing launches we might see trials of both, but certainly there won't be something readily available for service operations on the JWT at the time it launches.

This reminds me of a survey I had taken. I can't remember the survey publisher but it was related to self-driving vehicles.

You were presented two pictures (e.g. a picture of school kids crossing a crosswalk and the other a picture of an adult male and female walking their dog across a crosswalk). Presumably you had to choose; would you swerve to hit the adults and dog or would you stay course and hit the kids.

I know there is no moral compass for a computer system to determine what it should do in the scenario but I laughed at the quiz because I couldn't believe this is the kind of data that will feed machine-learning algorithms.

It just feels bad.
It's just some C# loops, and scanning the DOM for 'a' tags, and then analysing the 'href' attribute on them, and if there's a match, put it in the array. What I wanted to share was the methodology I used to solve the problem.
Interestingly, Microsoft briefed in support of Google this round in contrast with the copyrightability round.
Before attacking huge swathes of the population especially about their ignorance, try doing the tiniest bit of research yourself. NASA has always had high approval ratings--just below the CDC:

http://news.gallup.com/poll/121886/CDC-Tops-Agency-Ratings-F...

I think you will find that people's ignorance about budget particulars are reasonable--it's simply not a day-to-day concern of anybody outside of the GAO or similar bodies. But to say that people are anti-intellectual is just wrong. People are fond of the CDC and NASA, and if NASA's budget was wrongly said to be 25 percent, it probably reflects people's misunderstanding about the good government does (that is, they think it does more good than in reality).

They seem pretty different. Not just in how the data was collected, but how it was then used.

The research into Facebook likes and personality and the manipulation of those psychological profiles, which CA based their entire operation on, didn’t even exist in 2008.

Comparing the two is absolutely a false equivalency.

And the CA scandal goes way beyond the Facebook stuff. The company is allegedly involved in various illegal and anti-democratic activities around the world. Are people really downplaying this simply because they support Trump and CA has a Trump connection?

That doesn't just sound insensitive.

Watching the video, I'm convinced that person died for no good reason beyond Uber rushing tech out the door before it was ready. An alert human would have braked and swerved in that circumstance.

People do die from drunk driving, and those drivers go to jail because they fucked up in a huge way. That's no reason to give Uber a dead-person mulligan. Indeed, it's a reason that some Uber exec should perhaps be wearing an orange jumpsuit over this.

I'm all for self-driving cars, as done right deaths will go down. But that means we shouldn't introduce them until they are well-made enough that deaths actually go down.

It's disingenuous to complain about how public transportation is being undermined and to propose regulations that would force more people to use it without even mentioning the sorry and stagnate state of public transportation in many cities. It is simply unfit and unsafe to use in many places (including parts of NYC and SF) due to congestion, cleanliness, delays, discomfort and many other reasons. No surprise that many people have given up on it.

Any sane self-driving system needs to be a lot smarter than this. It needs to do motion tracking and estimation of future position. Otherwise it's going to run into lots of cyclists and pedestrians, and continue to fail for objects it can't identify (imagine a cyclist carrying something big and bulky). The software needs to be smart enough to not hit anything, and in order to do so it needs to extrapolate future positions of objects based on their current velocity.
It's optimistic to believe it mostly affects gullible people (whatever gullible means to you).

I've wondered the same thing. Same with Mars rovers, instead/in addition to designing a completely new one couldn't we have built a few of the previous generation at a fraction of the cost. My experience in science is that it was easier to get funding for new and exciting than old and already been done even if there is very interesting science to be done in both circumstances.

> if you take drawing seriously the "usual" iPad is easily not an option.

If you take drawing seriously the 60hz refresh is still fine - no artist I know drawing on the original iPad Pro ran out to upgrade solely due to Pro Motion/120hz refresh support.

For sure having a higher refresh rate is _nicer_, but not having it is hardly a deal-breaking flaw. My wife draws voraciously on an iPad and while the difference was noticeable to me if I really look for it, she didn't even pickup on the improved refresh at all when she tried a model with Pro Motion for a while before going back to her launch 12.9" model.
I guess it makes sense that Uber disables Volvo's own system so that it doesn't interfere with Uber's "safety" system. But why does Uber does worse than Volvo when Uber has access to more advanced sensors (lidar)?

Radar-maker says Uber disabled safety systems
I doubt there's any way to easily estimate the cost, but the two HST-superior telescopes NASA was given by the NRO, need to be made science-ready. There are no instruments on them.

Say for example that the cost would be $500m to $1 billion over several years to get them ready, then another $1 or $2 billion over ten years to operate them both. If you're NASA and you have $23 billion to spend per year average over that time, do you invest into the two telescopes and divert resources, or stick with HST until its end and focus on Webb. Obviously if the US Government were behaving more rational, NASA would be given the resources to prep these telescopes and launch them. They're exceptional gear going to waste, surely we could task something interesting for them.

I thought at first the fact that reuseablity is not mentioned as one of their goals was a big problem with their business plan. If the Falcon 9 Block 5 really becomes highly reusable, according to Elon Musk's criteria, SpaceX will be able to scale up launch rates and scale down prices that, by the time this rocket is available (2021 stated, delays likely), it won't be able to compete on price. I was thinking, "The more people working on different rockets the better. Hope it works out for them in that niche."

But going to their website[1] this launch market does not seem to be the company's main focus. They want to develop the technology to build currently very complicated objects with two orders of magnitude lower parts count. This is desired so that the products can be more easily built on Mars. I can see that as a long term profitable outcome with applications on Earth along the way.

From their mission statement[2]:

In the early days of settlement, there will be few people living on Mars. Intelligent automation and lightweight, compact 3D printing are fundamental technologies needed to quickly build a new society with scarce resources - and the most scalable means to get back home.

An ambitious goal (with an incongruous phrase tacked on the end??).

No one's going to use WebGL as an alternative to the DOM until it supports accessibility (read: being visible to googlebot)

Even if it did, you'd still lose a lot of productivity with it if you're used to working with the high level of abstraction of the DOM, e.g. line wrapping.

There are certainly cases where dropping to GLSL is the only way to get a UI to work at all, but most of the time the metadata-providing feature of HTML is far more important than squeezing some milliseconds of performance.

I was unaware we had more, so this is pure speculation, but I would imagine that having continuous coverage is considered critical, so if we launch another one and it experiences a failure soon after the current Hubble fails, we’ve lost that margin of error.

Fundamentally it’s much safer sitting in storage.
Nothing particularly scandalous comes up in this article. Completely unsurprising that Uber disables whatever self-driving ability the car already has to test their own solution. What is mildly interesting is the claims that had it not been disabled, the Volvo supplied self-driving software may have prevented the crash. However, I don't know how reliable that is and could just be PR at work.

What about the idea that pride is the most important value to certain people and pride sometimes comes from your wealth, achievements, and performance relative to the rest of society? The paradox would then be that as society becomes wealthier, the gap between the wealthiest people and average people widens in absolute terms, broadly increasing negative emotions.

Maybe immersive VR solves this by allowing the mass of people to transition from "lives of quiet desperation" to being rulers of their own miniature virtual worlds.
Gig workers wish they could be serfs.

I do gig work. My experience of it has been positive. It has allowed me to work when I choose to and to relocate someplace cheaper so I could get back into housing. It has allowed me latitude about some things that you typically only see in very privileged groups, like the Jet Set or well off retirees.

I know this isn't true for a great many gig workers. But I wish we would focus on ways to make it a positive for most workers rather than just talking about it in damning terms as if it can't be a positive.

See, an R7 family launch vehicles - complete dinosaurs. Both complex, and lengthy to assemble, in addition to having monstrously complex launch sequence. What you say about that is totally true.

But there is a big BUT - being complex does not preclude them being produced like sausages with big enough manufacturing complex, big and competent labour force, and very good rigid procedures perfected over 60 years.

In comparison to the cost of the whole space program, launch vehicle costs are almost microscopic.

Every rocket is a project, not a product.

Every rocket launch is not a service, it is also effectively a project.

And it was an achievement of the crippled post-Soviet space industry in making launch vehicles and launches more close to being a product and a service. Prior to that, a commercial satellite launch was hard to do without spending an eternity doing talkshops with likes of Boeing, Lockheed or French government. When ex-Soviet rockets popped up on the market, procuring a satellite launch service turned, figuratively, into a grocery shopping.
Yeah I do.

Have you actually talked to some of these people who are food insecure? I have yet to find any that are going hungry because of total lack of resources. I've talked to one family who said they never have enough to eat with their $400 per month SNAP benefits. I showed them how they could make sure they had food for every meal with a fraction of their budget and then use the rest for variety and to take advantage of what happens to be on sale. They said, "Yeah but my family doesn't like to eat rice or beans or oatmeal. The stuff we will eat costs about $300 per week."

Other families send their kids to school hungry, but yet have money to spend on lots of other recreational uses (both legal and non-legal). I personally know a family that didn't have enough money for food because they had just spent hundreds of dollars on a new dog and dog food.

If you give people the right to spend their resources as they see fit, some people will spend those resources in ways that prioritize purchases other than food. In other words, if everyone is food secure then it means at least some people are not deciding how to spend their resources for themselves. If you think people should be able to make their own decisions, then you have to accept that some people are going to run out of money for food from time to time.

That isn't to say that there isn't anyone in the US with hard situations that are out of their control, but I have yet to find a family who consistently has no food where it isn't directly related to how they are prioritizing what they do have. I'm not saying they don't exist, but they are a very very small fraction of the numbers you are citing.
Why is it a bad thing? What is the alternative? To have every single person in the world work for themselves? That's really the only other alternative besides not allowing businesses to retain any earnings for growth and expansion.
