nah, Adobe's just seen the massive benefit to their annual bottom line for anything with a subscription model, so it seems a neat fit to bring in a subscription eCommerce brand which is, in a practical sense, the nexus of 'Creative', code and web application.

Frankly, I now hate Adobe with a passion (because lock-in rip off), so I don't wish them any luck.
Jupiter's orbit is fairly circular (eccentricity about 0.05). How does an extrasolar obeject get captured into such an orbit?

I read somewhere that in-system asteroids could be captured into circular orbits (Phobos, Demos at Mars, lots of moons of Saturn and Jupiter) if they're originally half of a binary asteroid. The other half gets kicked away to circularize the remaining half's orbit. That doesn't seem like something that could happen to put an object into retrograde orbit around the Sun.
No every challenge he puts forth demonstrates he has no idea about how modeling is used. He also clearly has no idea nor interest in the current state of astrophysics and astrochemistry if he's declaring that we definitely know nothing about planets we observe.

By his own "logic", we can't even be sure they're tidally locked (because how did we determine that? Modeling!) Which I mean, is technically true because hey welcome to science where confidence intervals are a thing.

And make that table WIIIIIIDE. There are so many useful attributes for query time and to be exposed as filters/parameters in reports for end users in a more self service mode.

Flags for whether the day part is YTD, MTD or similar, so you can easily select the set of days that would be in the YTD period for any year. This is super helpful for a multi-year comparison of YTD. So right now, everything from January 1- May 21/22 (depending on your edge case) would be YTD=1 for all years (not just 2018).

Contiguous, monotonically increasing indices for any date period - weeks, months, quarters, trimesters, semesters - especially helpful for fiscal calendars where the entirety of built-in date functions become worthless. Last period is always the index of the current period minus one. All date shifting logic becomes trivially expressible as basic arithmetic on these indices.

Pre-format dates into all the common display formats you might use. Just extra strings in the table - super useful for your non-technical report authors and self-service analytics consumers - don't worry about the cognitive overhead of teaching dozens-thousands of people how to use format strings effectively (they won't - they'll just pull it into Excel), when you can trade a tiny bit of storage overhead to give them all they want up front.

Give a simple "IsWorkDay" flag - include all your company holidays and weekends here. Also separately include an "IsWeekDay" flag and an "IsHolidayFlag". If you're concerned about storage, please count the number of dates - you need that many bits to store each of these flags. This is ~4.5KB per flag field on a 100-year date table. Even if you're storing things inefficiently as BIGINTs, it's ~292KB per flag field. This is pathetically small.

I really can't emphasize how useful this sort of thing is for fiscal calendars. A calendar is just a hierarchy whose base unit is a date.

Everyone's dates are the same. They just belong to different categories (Month1=January vs Month1="first four full weeks in the calendar year"). Those categories are defined as contiguous and non-overlapping sets of these base units. We care an awful lot about the inequality invariants of members of these sets (months, quarters, etc). All of this stuff can be exposed through a table that is updated for certain flags, or just a base table of static attributes and a view for the "dynamic" components.
You do know there is an enormous difference between paying for a subscription and letting your gym MITM you/pick your pockets for info, etc, right?

For example your gym might have video surveillance, which is fine, but it has to have a sign and they can't use the footage for anything else than for security reasons without asking you first and they have to delete it after a certain amount of time. They don't have to video tape you and then sell the footage to the health store next door in order to advertise to you in order to let you use the gym.

While I agree with most of the other comments that there's little evidence for the argument of the article, it is refreshing to see a different take on the whole "earth-like planets" topic.

I am regularly shocked by how little imagination commentators in the popular science press seem to have on this subject. Even highly-respected scientists frequently refer to "requirements" for extra-terrestrial life such as carbon-based chemistry, the requirement for water, a mechanism of natural selection, etc, etc. (Actually I consider the last one, posited by Dawkins, to be probably the closest to the truth.)

I guess it's simply the anthropic principle at work, but even the nature we see on our own planet far surpasses our imagination often (especially at the microbial level), so why should we be placing any constraints on the rest of the universe?
It was anyway. Now they're a blessedly rare species.
We also don't have timescales for abiogenesis in a sterile environment - i.e. given the right ingredients and energy input, no existing life forms...how long does life take to appear? There's no particular reason that timescale has to be very long - and we know life on earth got started pretty damn quick after the planet cooled off enough (EDIT: in the sense that the planet is ~4 billion years old, the earliest life is dated to 3.5 billion years old, so the number is somewhere between a little over 0 and 500 million years).

I think it was an old BOFH story that said "when the model and the company have the same name, I know I"m in for a bad time". There's a lot to be said for having your app's developer be a business, rather than your name or worse, your app's name.

Tango you might be another fantastic exception to add to the small list of late starters who got to GM level such as John K. Shaw and Jonathan Hawkins.

However I suspect that everything else being equal children do have a higher skill ceiling because there are very few late achievers in chess.

An experiment would be needed, take a group of 10 year olds, 20 year olds and 30 year olds and immerse them in intensive 5 year course of study.

I would wager that the 10 year olds as a group would have progressed further.

Why do I say so? Because, it is incredibly hard as an adult to obtain the so called unconscious mastery in any field. (Ie what Gladwell alluded to in 'Blink'). It is the pattern recognition that's been alluded by many.

With kids this can happen, 'the jump' so to speak. With adults I've not seen it happen in almost 40 years of playing chess at a decent level(FM).

I remember it somehow clicking for me at 14 for chess. It is the level when you do not have to think and you can make a good move. It was the level when I realized I could keep up with IMs.

Of course you need both pattern recognition(GM-RAM) and the ability to calculate. Ability to calculate can be trained, but it is also part of talent/ability.

Among my kids and nephews only one has that ability.

Are you going to tell me that among your adult students all have the raw ability/potential to make master?

OP here, couldn't agree more regarding commenting[1]. Far too often people don't treat their SQL queries or database the same way they do code.

That's a good read for library developers. Ideally libraries should be a little bit adapted for Graal. I think it's an important project and compatibility is good, most developers won't be able to overcome those problems and just won't use Graal at all if popular libraries are incompatible out of the box.
I'd imagine it would depend entirely on the type of search you're trying to do.

If you know all the possible ANDs and ORs beforehand, you could pass in flags to select which ones to use. That would also mean you could prepare queries ahead of time, and not need to compile them every time you run them.

I don't think there would be many situations where you wouldn't know what possible filters you could have at compile time, and in such a situation I'd question whether there was a better way to implement what I was trying to do.

For games, I seriously doubt this advice. Getting to 'hot' or 'featured new' or whatever the category is named is a huge source of no-ad-spend success, and it depends on getting a lot of new downloads shortly after release. A/B test before you release, sure, but don't release multiple versions and split those key early downloads.

(Also, you're going to annoy all the users of any fork you deprecate, unless you maintain all 5 pages and move them to the same source. Also, will Apple even let you do this?)

Pastors deal with so much frustration every day. Working with people in any job is messy and can be very draining. In the context of a church, working with people is significantly messier and more draining.

I'm sure it justifies a much more nuanced consideration, but at a crude economic level, I suspect gangs provide protection and economic opportunity in exchange for physical and legal risks; Norway provides both of those opportunities, to a high degree and to a broad section of society (social mobility in Norway is high), with much lower physical and legal risks attached, so there is competition for what gangs provide.

The GIF Controversy
Carbon-based chemistry isn't the worst requirement to throw in there, since the only plausible analogue - silicon - for example doesn't form stable analogues of the usual amino acids at room-temperature.

Now it would be reasonable to say "well what about extreme environments" but we are specifically looking for planets with temperatures and "ambient energies" similar to ours - so it's reasonable to think that whatever chemistry is there probably has to follow Earth to a large degree.

If instead we were talking about high-pressure hot Jupiters or something, then it gets more interesting - but that's going to be something so different we're unlikely to recognize it at all (what consciousness does sentient life which evolved in a gas-environment have?)
This is my problem with SQL in general. The facilities for which SQL is an API are incredible, but that API has so many weird design choices behind it that it often feels like I'm being forced to play some kind of perverse minigame in order to get the database to do what I want efficiently. And then, once I've managed to bend the query planner to my will, I often have to load it down with an absurd number comments to explain to future folk what exactly is happening – ostensibly the sort of thing that a declarative language is supposed to prevent.

A/B testing should generally be done within an app, though. If your app already calls home to a server, you can collect usage stats and send feature flags for A/B testing. If it doesn't, you probably have to run your tests on in-person groups.

The parent here proposes releasing multiple versions of an app and seeing which ones get downloads, which seems much harder and riskier - you end up splitting downloads across multiple apps, and then have to deprecate or maintain the ones that don't work out well.

> [...] except for devices such as winglets

You answered your own question and didn't know it.

If the additional width added here has no net lift benefit but served as winglets do to reduce induced drag from the 'mixing boundary' but even more effectively – since the outward moving airmass doesn't have to accelerate (read: change direction) when it hits the base of the winglet, but instead gets to continue smoothly migrating to the tip – I can absolutely see how that would pay off in efficiency gains.

Wings can be designed to have nearly arbitrary amounts of lift: reducing drag for a given amount of lift is the secret sauce, which could very well be what this design achieves.

> Can't help but dream that private prisons could do like this

Why would it matter? Are you operating under the assumption that they would then pass those savings along to the government? That's not really how privatization works.

Private prisons don't care about saving the government money, they care about maximizing profit. They say they can save the government money by offering to perform an existing service at a lower cost, but not dramatically lower. They negotiate minimum prison populations, thus ensuring a baseline income. They then proceed to do the absolute minimum possible to fulfill the contract while cutting costs in every way imaginable. There's no long term consideration given to sustainability of their practices or benefit to the prison population. Everything they do is to maximize the margins until the contract runs out and they can renegotiate for higher rates.

“Welcome to the Blockchain”: The basics of Blockchain and Bitcoin
Citation needed. In a two-level quantum system, if I make any measurement of a particle such that the distribution of outcomes depends on whether the particle is in state 0 or 1, then I have disturbed the state of the system. This is true no matter how fancy the measurement is.

This can’t even be avoided with hacks that depend on detailed knowledge of the system. If the initial state is |0>+|1>, then, sure, I can measure and then reset the state. But if the initial state was entangled with some far-away particle, I can’t reset the state of the nearby particle without completely forgetting the outcome of the measurement.

They only pay $5 per Bird per night. If each Bird "works" only 3 hours a day on 15 minute trips, that's about $30 a day earned per Bird. They probably get the scooters for ~$300 so each one pays itself off in 10 days. Call it 12 to account for damaged Birds. Extrapolate that out to say, 1000 Birds in a City, and that's at least $1MM in revenue monthly per city.
