Maybe it's just because I'm not the target audience for this paper, but I'm finding this very tough going. I'm a PhD student in a mathematical field (operations research) but have only the faintest idea about Kalman filters - something about updating beliefs based on noisy measurements in a way that feels intuitively similar to Bayes' Rule. I'm not a tutor intending to teach Kalman filters to anyone in the near future, fair, but I should have the mathematical background to get through this. Not sure why it feels like a slog. Maybe it's because the measurement and prediction and update equations appear before any intuition about what a Kalman filter is, what the stages of the algorithm are, etc.?

Edit: all the way through now. Certainly this would be much more useful as an intro to Kalman filters (rather than an introduction to introducing Kalman filters) had some intuition been given.
Dignity of work doesn't have anything to do with importance. It's about power relationships: vendors are in a different relationship with their customers than service workers are with the people they serve.

In Manhattan, a nanny probably makes more than a journalist--but is there any comparison in which job is more dignified?
Based on your side of the story it sounds pretty shady. Total speculation: maybe someone got a ticket assigned to them and slacked off, closing it over and over with a canned response. A rep can probably watch a lot of YouTube if they do that to most of their tickets. Then when you'd reopened it by replying enough times to make them worried about their manager noticing they fixed it quietly and closed it. Asking why it took so long spooked them bad enough to threaten you for asking questions about their service/response which I imagine is prohibited unless the customer is being hostile.

So what? Every person has a price point at which they will choose not to work. Especially when there isn't work for them.

There isn't a labour shortage. In fact, there is quite the opposite.

Or, more specifically, there is a labour shortage, but in fields that our economy does not seem to care to pay for.

The author is very blase about describing these men as having "chosen to not seek work". Discouraged workers are a well-known phenomenon in labour economics - people who have given up looking for work because they believe that they have no realistic chance of finding it.

America might have plenty of job vacancies, but it has very few vacancies for unskilled men living in rustbelt towns. For these men, the obstacles to finding work are often overwhelming. When graduates are struggling to find work, the prospects for socially disadvantaged people are very bleak. If someone has limited literacy, mental health problems or a felony conviction, I can't really blame them for giving up on the prospect of finding work.

And yet, the simplest interactions always disappoint me. I said "Create an appointment with John Smith at 2PM tomorrow". John Smith being someone who isn't in my contacts. Siri presented me with a list of my contacts that she thought I might have meant. The option "None of these" was also presented. I chose that, thinking she would just create the appointment with John Smith in the title as plain text like I wanted, and she said "All right, I'll leave it off your calendar" and that was that.
His characterization of Current Branch for Business (the 'Defer Upgrades' toggle in the Update settings pane) as blocking security upgrades for a year is a bit off the mark.

CBB defers major feature upgrades, like the Anniversary Edition which started rolling out recently, but you continue to receive updates for the build you're on -- including security updates. You'll eventually receive major upgrade build N when build N+1 has rolled out to consumers, and when N+2 rolls out, N becomes unsupported.

This option is only available for Pro and above, so Home users are essentially stuck in permanent beta-testing mode.

MongoDB is killing it in the Big Data space right now with excellent integrations with Spark and Hadoop, strong relationships with Hortonworks and Cloudera and really good enterprise support. I know many Fortune 500 companies and equivalents overseas who are customers.

But please enlighten us poor fools which open source databases can compete with MongoDB in this space. It sure as hell isn't PostgreSQL.
It also would have had to compete with Firebase.

Why does nobody seem to have any introspection on why RethinkDB failed? Clearly there are some major problems that people re ignoring. If my favorite DB (I must mention Kx Systems once a month) folded, I could give you a laundry list of issues where things went sideways, but all I see is glowing praise and comments about the best tech not always winning (KDB knocks the socks off of everything, but I sure can give you a list of places it fails).

This isn't meant to be harsh, but these are times to learn, not simply pat each other on the back.
His point is a little more subtle than that. When you're choosing a database engine to build your company on, knowing that it's open source provides some level of guarantee that someone will continue to maintain it if the company/developer folds, even if that someone is not you.

Therefore, if you're the one building the database, open-sourcing it de-risks your product to your potential customers, to some extent.
Good old common sense is lacking all throughout this farce. It's one thing to build a company on an existing technology, like Jobs did, but promise to implement it better. It's another to come up with a wouldn't it be nice if... scenario, and raise capital on it.

Are Silicon Valley investors stupid enough to throw their money at any bright young dropout with a change-the-world idea? The fact that some Ivy League dropouts found billion dollar companies does not mean a particular Ivy League dropout chosen at random (or one of the many who express a desire to change the world) has a non-zero chance of returning $$$ on investments.

Demonstrating that inteligence and common sense are seperate traits, the latter not always accompanying the former.

One thing I wish is that they had Mitch Epstein do the commission ala American Power[1]. Not to knock Steinmetz, I just like how Epstein takes in a scene and presents it ambivalently great and obscene.

I've worked with all the different types of Kalman Filters over the past decade, and one lesson I've learned is that there is no way to make it simple and intuitive. It requires extensive background knowledge in math and stats, and even then, it's very difficult for intelligent people to keep track of all the moving parts. Papers like this one are an exercise in futility.

Unless every single country all had UBI at parity. Then UBI and open borders are both fine.

That post is utter garbage. Seriously.

Most of the the points are for issues that were fixed years ago and then you get classics like "forces the poor habit of implicit schemas in nearly all usecases" as if some developer is going to somehow stumble on the fact is it a schemaless database.

It's like trying to say "Linux is shit" because of issues found in 1.0 of the kernel.

>People are not supposed to communicate only via papers.

A paper and its supplementary materials are supposed to be enough to reproduce the experiment. In practice, this often fails, but that is a fault in the scientific process. Science isn't just about empirical knowledge, it's about public and redundant empirical knowledge, as opposed to losing important knowledge of the natural world when the original investigator gets hit by a bus.

At my last workplace, I finally asked: "Since you guys bitch about mongo so much, why do we use it? Why not something else?". Response: "It's not actually that bad, it does the job".

Half the crap people speak about Mongo seems to be from either the early days, or from people who just like to complain. It certainly has it's issues, but there doesn't seem to be much community will to replace it with $superdupernosqldb.

Designing a SaaS Database for Scale with Postgres
I love Rethink and Horizon. Are there great risks in continuing to use Rethink even if development has stopped?
It seems like you're trying to deliberately misread my statements and take them out of context.

I'm saying that once you realize there's no trust between you and your boss, and your boss realizes the same, the motives become clear. If you're naive enough to believe your boss when he says that "the company has invested a lot in you" and goes into a song and dance, you're in a bad situation because you've demonstrated that you're unable to recognize situations you're in.

> It's relatively clear when this is happening, though, because it's hard to hide when your replacement has been hired.

Often it isn't. He could either train from within, or slowly get people to start doing stuff that was usually on your plate, as is his right.

> Again, it's relatively clear when this is happening, and in this case you may be able to work out a deal.

Again, that is not relatively clear. He could be vetting consultants without telling you, and then blindsiding you, and at that point you've already lost your original offer (some of the time).

> Let's be clear here: at every job you've ever worked at, you're a cost center, and if you've worked yourself into a high-paying position, you're one of the largest cost centers.

Incorrect. At a consulting job, you are the product, and you are a value creator, not a cost center. The more they can bill for you the more they want you around. I can guarantee that they'd rather have you than a fresh grad.

Basically, I don't understand your hypothesis. You're saying "Oh, you can figure it out, so accepting a counter offer is ok sometimes". Sometimes it is, but most of the time it isn't, and you can't often tell the difference between the situations up front.

You will lose the original offer that you used to get the counter offer a lot of the time, and you're on an extremely short leash at work, really exploring the limits of at will employment, especially if your boss is the kind to hold unreasonable grudges.
I'm not sure you can chalk this up to a failure of capitalism. Postgres is a tough database to contend with and it's mature and open source. People like to hate on mysql/mariadb, but it also has a massive open source community.

As a company choosing open source technologies, the popularity is important. Otherwise you run into issues finding answers to common problems and you end up paying through the nose for support.
Sure, from a protocol perspective, arranging it so nobody, even the original owner, can decrypt the communication after the fact is beneficial, except that now, you end up with people downgrading such communications or storing the session secret keys, the latter probably by patching software crypto implementations where possible (since I doubt any of the major crypto implementations would agree to storing those keys even with an --i-am-a-developer-really-stop-bothering-me flag).

I hope I'm wrong. I don't want to end up in a world where all enterprises actively MITM and negotiate down to non-PFS protocols to avoid this, or hack up the software stacks on their machines to circumvent this (with all the overhead that implies - echoes of "requires Internet Explorer 5" for how old some of this will probably get between updates).

I just don't think that the people who make use of this functionality are going to let it go, no matter what it takes.

(That's not to say it's not worth trying, to be clear - I just foresee it ending poorly for everyone except for private individuals, and possibly even them if ISPs start requiring you accept their MITM CA.)

Does anyone else have the feeling that the ecosystem lock-in inherent in all of these large primarily hardware-focused companies isn't necessarily the whole future? I can imagine things like airport kiosks, coffee machines, subway terminals, hotel front desks, and other everyday objects or conglomerations of objects that aren't part of the consumer market most of these companies target also having such an interface, and they may not want to give all of that to Google or Amazon for instance.

Making that software seems like a necessity to me (the "operating system" of the future) and I'm not sure how it fits in with the current trajectory. Thoughts?

Wow. I was seriously rooting for them. I'm looking forward to Slava's posts about their challenges on the business side. There's a part of me that's angry that MongoDB - which some would say has made an objectively worse product - has succeeded.

Dear Zipcar, here’s why I’m using your competitor
To clarify, I didn't mean pulling the app, or anything app-related at all. I just meant Amazon and Google both can have such Kafka-esque "you're not allowed to appeal" responses to issues. I've personally experienced it with Amazon, and have read about it with Google.
If a particular practice is acceptable for Apple, then it is presumptively okay for other software companies to do, too. And conversely, if everyone in the market for software-development labor wouldn't be allowed to do something, we shouldn't allow Apple to do it, either.

If a particular bit of conduct would be a poor idea if everyone were to do it, that's a pretty good idea it shouldn't be allowed at all.
But are people paying for it if MongoDB is "killing it". If not, no business model.
I fully expect a write-up on why RethinkDB failed in the coming months, we're going to have to deal with the practical consequences first.

If open source only works when you pay for it, it's just an abstraction layer around ordinary commercial software, with the same pressures. In fact, most of the people qualified to fix Linux video drivers are already employed full-time at a graphics card manufacturer (with its sales pressures) or a commercial redistributor (with its sales pressures). You could pay one of those companies for a support contract. But other than that, if someone else qualified exists, it's only worth their time to take these contracts if there's enough sustainable business to keep up-to-date with how Linux graphics drivers work; chances are there isn't, and they're spending their time in full-time employment doing something else entirely. So, you're at the same place where you started: the problem is complicated enough that there aren't enough reliable sales, and so it only gets done by large companies that can afford to fund the work because they already have enough sales of enough things.

(Full disclosure: I am one of the people who could have been qualified; one of the jobs I was considering a few years back was a graphics-driver-hacker position at Red Hat. I happened to instead choose full-time employment doing various, mostly userspace Linux stuff for a startup. When they ended their incredible journey, I would have loved to make a living taking contracts like the ones you suggest - and I still wish I could - but there aren't enough of them and they aren't reliable enough to make it better than just taking a full-time job with a profitable company.)

Non profit companies still need to make money to keep the lights on. That means targeting technologies that can attract lots of donations. Databases are a very mature technology so the number of companies running into issues with them is vanishingly small. Who is going to donate to a non profit spending its time developing a solution a problem almost nobody has?

>I have come to believe that the main purpose of hiring scientists in academia is to keep knowledge alive and have it passed on to future generations.

Then these scientists should be devoted to producing textbooks and courses which can then be taught to non-research students. Yes, all knowledge about the scale of what a single individual knows (and keeps on their shelves, hard drives, etc) is embodied as communities and traditions, but we still get far greater redundancy of that knowledge from teaching it as undergraduate or master's-level coursework than from passing it down only via research mentoring.

If 25% of the population gets an undergraduate degree, 11% or so gets a postgraduate degree, and only about 1.7% get a PhD, then we need to be embodying society's knowledge among the larger cohorts for that knowledge to survive. We can't afford to live in a world where only 1.7% know how things work.
