More Than a Data Dump
Amazon directly competes with 3rd-party sellers. I used to sell various products on Amazon about 10 years ago and as soon as I started seeing a decent amount of sales, A listing would appear by Amazon (not a 3rd-party seller) and undercut me. My sales would soon disappear after that.

They clearly use your sales data to make money and directly compete with you. This combined with their atrocious support for sellers has turned me off to their marketplace completely.

Ebay, on the other hand, doesn't do this and I think this is why Amazon is able to make so much more money.
I get the same gut reaction as you, but I tried reformatting the code a little bit and it's not _that_ terrible.

From the very little APL I've learnt, I know that operators always have either one parameter (named ω) or two (named α and ω), and their inputs and outputs are always arrays.

If you need to write a lot of such functions, it makes sense to define some macros to help you:

#define V1(f) A f(w)A w; // create one-arg function
#define V2(f) A f(a,w)A a,w; // create two-arg function
#define DO(n,x) {I i=0,_n=(n);for(;i<_n;++i){x;}}

iota is the APL equivalent of Python's range function:

V1(iota) { // Define one-arg function iota.
I n = *w->p; // Get the value of the ω argument.
A z = ga(0, 1, &n); // Allocate output array.
DO(n, z->p[i] = i); // Assign increasing integers.
R z; // Return the result.
}

The plus function adds two arrays:

V2(plus) { // Define two-arg function plus.
I r = w->r, // Get the rank of ω.
*d = w->d, // Get a pointer to ω's data.
n = tr(r,d); // Get tne size of ω's data.
A z = ga(0, r, d); // Allocate output array.
DO(n, z->p[i] = a->p[i] + w->p[i]);
// Add corresponding values of α and ω
R z; // Return the result.
}

Personally I cannot tolerate the lack of whitespace, but the APL guys are known to like to see their entire programs in one screenful. I can understand that some people like to write code like this.

>Not because the MacBook sucks, but it just sucks working on a single small monitor

Not that this is totally up to taste. Some people love working on a single smaller monitor, with only a full screen editor or some terminals. More focus.

(I used to love it too, but I can't stand the modern MBPr keyboards, so I connect it to an external keyboard and monitor now. Note that I love the external "Magic keyboard 2", it's just the built-in laptop keyboard "butterfly" that I find crap).
I don't see what you can't do with neo4j, neptune, datomic. Neptune offers a sparql interface. You could easily specify an explicit schema. If you wanted to make an ontology that's globally unique you could force it to be defined at a centrally defined application level. If you wanted a inferring traversal, for example applying some type of hierarchy, you could write your own iterator in java in neo4j if you wanted to, or just apply multiple types to the vertex.

I find it strange to suggest that he is using sockpuppet accounts on HN without any proof. You may as well be using sockpuppet accounts to promote Matrix. It is also really suspicious to attack someone that has spent a significant amount of time on your project.

Yeah tonmoy linked to the blog post that had the predictions. Unfortunately, the model pretty much predicted a higher probability for the higher seeded team in the matchup which lead to some relatively expected predictions. If I remember correctly, it led to a pretty average percentile (50-60) when I submitted it to the ESPN leaderboards.
Combinations and Permutations, C++ Implementation
Yet another example where a user data profile is created and anyone but the actual user whose data it is will claim that the data is theirs.

It's the (now-)unsavoury point of platform businesses, who step into the business relation between a user and a service provider to mine and aggregate and profile data to provide value in a surveillance economy. Would this even fly in GDPR-land, where you can only process data within the narrow confines of the actual business relationship?

Someone that works in the industry probably knows better, but OpenTable has your full history of your dining experiences booked through them. What restaurants you frequent, how often, what time you go, how large your party was, how often you failed to show up.

I believe when you booked a reservation the restaurant got to see all of this.
My stepmother uses one to browse Facebook. It's the only time I've ever seen an adult use one.

Even more basic than that, zoning and development regulation have strongly - in many cases explicitly - racist origins. For example many the first zoning laws in SF were designed to push back against Chinese immigration.

Those same tools have been used to the same effect, and strengthened, for generations. Yet for all the calls for social justice in society now, I almost never hear people calling for the end of zoning, when it may be the greatest perpetrator and enforcer of inequality today. In the Bay Area, zoning is the saw that has cut the bottom off the economic ladder. It’s surprising to me that more people don’t understand that intuitively, but alas.
They offer education discount as well for $50/yr plus the $69/yr renewal someone else mentioned. So it’s definitely not a clear $100M mark but I’d say they’re doing good
Seconding this. I'm a wannabe hobbyist type designer and I found FontForge to be prohibitively difficult to use. I'm sure it's wonderful once you sink in the many hours needed to learn it but I just want to drag around vectors and try things out. Like you, I don't know for sure if Crossfont hits this sweet spot but I would love it if someone managed to do so.
Less that and more the combination of bad tools, labyrinthine “standards” which were usually poorly implemented by said tools, and lack of concrete use-cases. Almost nobody had a case where implementing it showed a clear business value so most of the “you should do this” advocacy was along the lines of “this will become useful later” and that was a hard sell because it took many years before you could go to a webpage, read some decent instructions, mark something up, and run it through a validator or another client and get the expected data back out.
Yes! I was in delhi and kathmandu and wished that i had some mask to filter out the awful air pollution. My lungs and throat felt sore, and in the end i developed a cold which eventually led me to being bedridden for a day. I cant fathom how the regular people can tolerate that toxic from day to day, it's just awful. Maybe they cant but the overabundance of mopeds and lack of sidewalks makes me think otherwise.
Seriously, when I first moved into my new house in Boston, two months in, I saw a little mouse in my kitchen and I literally lost my shit. I've never even imagined seeing a freaking mouse in my living space. My roomies were like "ooh don't worry, that's normal. We can just call the exterminator tomorrow and it'll be all good." Apparently this is a totally normal thing in large cities in the East Coast like New York or Boston. Back in Bay Area it was normal to see mice or racoons in the streets, but I never even considered the possibility of seeing one inside my house.

It's interesting how tiny cultural differences (having cats in the city) can cause you to make such assumptions about human living conditions. Before moving to US, I would consider seeing mice an alarming and totally abnormal situation. It's like seeing a snake, or scorpion, or bat in your house.

Unfortunately not everything has been studied. For my case, there are a lot of celiacs that report sinus headaches [1], but I can't find a single paper on it. Is it a real problem? Definitely, I would love to be able to eat whatever. Can I point to research? Nope.

Thinner makes sense for the iPad, I hadn't noticed that.

The current MacBook is thinner than the MacBook Air released after it though. The fact that they're different screen sizes muddies the comparison a lot though.

Pure anecdote, but when I was visiting Vietnam (Saigon and Can Tho) recently, I would go up to the rooftop balcony in the evenings and watch the birds and then bats out hunting their (insect) dinners. It stuck with me, because the numbers of birds and bats seemed much higher than I would normally see in the urban Midwest here in the US.
Right, I have wrote that in my first comment:

> Google will only show result from that domain if you limit search to that domain with “site:karmadecay.com”

The question is, why doesn’t normal image search show that site ever, despite tons of content?

I know technical reasons are still possible, but so is google breaking laws, they have quite a history of unlawful behavior and have paid billions in fines for that.
As a web developer, I'm always surprised by the lack of HTML knowledge by most web developers (including myself). Sometimes we spend a long time developing a component when there is a perfectly good HTML tag with better a11y and i18n support available.
Not the OP, but on my recent trip, I used Apple Books.

The big advantage for me was that I could visit travel websites with lists of things to do, save website as PDF, made annotations of places I wanted to visit.

It synced seamlessly across all my devices along with annotations. I annotated on my iPad at the hotel, and traveled with my iPhone.

Both of the technologies you named as examples are free and open. Anyone can inspect them and deploy them on their own. Slack isn’t like that unfortunately. This is a move to add another feature that will attract enterprise customers, I would doubt that even Slack themselves would proclaim this as a move towards greater software freedom.
I think it all comes down to semantics, and the exact definition of "threat". If you define threat as warning someone that you will do something that will negatively affect them, then threatening to quit absolutely qualifies as extortion, just as Comcast threatening to turn off your internet service if you don't pay your bill also qualifies as extortion.

As I said in another post here, Wikipedia's definition of extortion is: ""Extortion, which is not limited to the taking of property, involves the verbal or written instillation of fear that something will happen to the victim if they do not comply with the extortionist's will." Getting your internet service is a negative thing, so and Comcast's will is for you to pay your bill, so I think it fits the definition of extortion here. As do all contract negotiations.

In summary, I think these definitions need a lot of work.

I wonder if we can get people out of cars unless cities themselves are completely redesigned. We committed ourselves to a harmful design pattern but unfortunately everyone is heavily invested in it. Need to have a city design that will work, and then draw up a series of implementation steps to move existing cities to the new design. Would require a ton of central planning/control though, doubtful we could pull it off unless things got drastically worse to motivate people.

Can't find any science in that article or its links? Just pop culture references.

I think you might be right - I know quite a few people in their 70s who love the mini. They were quite upset 6 months ago when I was telling them it looked like it was going to be discontinued. I guess all those predictions of its death were wrong!
Kaitai doesn't (currently) support writing out data, only reading it in, so this is fairly different.
>"I like driving," should be enough.

Ok, what if I like shooting guns, and I like shooting them in crowded places. So why shouldn't I be allowed to do that, and why should I be punished if I kill someone that way? It was just an accident, after all, right?

Remember, 40,000 people die on US roads every year because of your attitude.
The article isn't terribly specific but presumably dining and spending patterns of various sorts that can be valuable in the aggregate.

I have to confess that, as a user, I find it useful to be able to book the maximum number of restaurants through one or two apps whether or not they also support making reservations through other means. Especially on mobile, I'm not a big fan of navigating through often crappy web sites and potentially having to provide a bunch of info to find there are no reservations available at 7pm. OpenTable is just a few clicks.
I think it depends on your idea of suburbia. We tend to have smaller cities surrounding our major city. These smaller cities have mixed use neighborhoods - commercial and residential - and lots of multi-family homes. I grew up in such a city in a multi-family home (locally, we knew them as tenements). An article appeared recently about the trend toward purchasing multi-families again due to their cost-effectiveness. So, I'm not certain of the 30-somthings move to the burbs trend yet.
I lived on a college campus for two years, which I think was like a microsm of walkable city. Food, academic clubs, classes, everything in walking distance of the dorm. The social aspect didn't work out for me that great, walking was tiresome. I didn't mind eating out all the time with the meal plan but groceries would've been healthier. I really enjoyed the setting with the nice streams/ponds/wildlife but that's where it deviates from the standard city experience unless you go to a park. It was great being able to sit in the grass and watch a great blue heron catch a fish after slowly staking out the area for a while.

In comparison to my experience walking 10 minutes to my farthest class some days, I much prefer driving for 10 or even 15 minutes. I just really prefer living in a setting like the house being surrounded by forest on at least 3 sides and having enjoyable countryside drives to stores. Can't speak for everyone but I'd only tolerate living in a city for a job ot something if I didn't have to do a lot of walking/NYC-style transit (I've used the MTA subways a few times and they are efficient, but too crowded/jerky/it's stressful running around between connections)
The universal credit digital obstacle course
Or live in an area (design and build areas) with good childcare options within walking distance. (Where "walking distance" is up to a mile away, not what Americans have gotten used to.)

Modern car seats and LATCH anchors actually make it fairly easy to bring a child car seat with you. I agree with you though, all this stuff is bulky and adds up to a lot of baggage. It makes sense to have a car for your child. But those cars create enormous problems, and car owners should be required to pay to fix them.

You say "that's not true either", but really, it was never true in the first place. Traditional taxonomy is bad at determining how related species are. If you want that, you look for evidences of common ancestors, or do DNA analysis.

I tried digging through Wikipedia articles on taxonomy, but it seems to be a bit of a mess, with different articles in the hierarchy using different, incompatible sources. It looks like rodents and primates are both members of clade Euarchontoglires, with common ancestors 85-95 mya.

https://en.wikipedia.org/wiki/Euarchontoglires

Clade Laurasiatheria is a sibling containing pigs, cats, whales, bats, and many others. Common ancestor with primates is listed as ~80-100 mya (yes, this number doesn't match the other one).

I'm 70 and have an iPad Gen 3 (2012), an iPad mini Gen 2 (2013), and an iPad Pro (late 2018 Gen 3) + Apple Pencil Gen 2. I'm pretty sure if I were under 25 I'd be just as stoked about them — though prolly unable to afford them.

I'd extend this from "kids" to "dependents". Anyone trying to move a disabled person, or simply an elderly relative, will opt for private transportation. For me it is a question of reliability. If the train is cancelled, the bus is late, or the power goes out, the private car allows a degree of privacy and safety unmatched by public transport. You think changing a kids diaper on the train is bad, try it with a 150lb wheelchair-bound adult, one who may not have the mental capacity to understand why the train has stopped.
I'm wondering if the appeal of these begins when you get older?

I am 36, I had several iPads, but they always end up gathering dust in a closet. For work, I am several times more productive on a laptop, for occasional browsing, e-mail, etc. iPhones have become large enough. So, at some point I just sold my last iPad and never bought a new one.

My wife also has an iPad, but only uses it quite rarely. And when she does, she usually finds that she has to charge it ;).

Others have mentioned iPads as a kid's device. Our daughter (5) likes the iPad, and occasionally uses it to program her Micro:Bit. Other than that we've found that most iPad apps for kids aren't all that great, so we just prefer physical books, sketchbooks, paint, Lego, etc. She loves Lego and paper. She probably uses the iPad every month or so. She did get a Nintendo DS recently for playing games, though we do severely limit the amount of DS screen time though.

We are considering to buy her a NUC with Linux, just to tinker. My dad allowed me to poke his MS-DOS PC when I was about her age. I loved it and learned a lot. Since she likes her Micro:Bit a lot, I think she'd do well on some non-walled garden machine. No pressure though, we'll just put it there and see if she is interested or not.
It's also good for reading. I'd rather have my iPad than my laptop when I'm reading books and taking notes (some notes, if I were in school I'd still want my laptop for that tempo of note taking). I use it a lot at home and the only media that I play is music (with headphones) and then read a lot of books and such with it. Scrivener is pretty good on it for writing, but I don't have a keyboard for it anymore (my wireless keyboard got damaged in a move somehow, still not sure what happened). It's also nicer for tossing in my shoulder bag with a physical book and notebook than dragging around a laptop.
