>I'm not really understanding the mortgage point, but you bring up an interesting point of treating "multi-listing" hosts as bad actors. If we approximate it by saying 45% of 9550 are bad actors, that's still only 4300 listing. That's still tiny relative to the Toronto rental market. To be fair, the realistic number could be a lot lower since a multi-listing host might be hosting multiple bedrooms in a single house and inflating the # of multi-listing hosts, or they might be hosting their primary residence and an investment property where only the investment property is a bad actor.

So, here's another article i found on BBC, and tbh i hadn't even considered this point. A lot of airbnb units usually are in more desirable neighbourhoods, thus decreasing supply of rental units in these areas and in turn increasing the price of available units to rent. Renting on Airbnb nets you 2-3x the median long term rent. In LA, almost half of Airbnb listings were clustered in seven neighbourhoods, where rents increased a third more quickly than the city average.

Now if this is isn't a direct enough proof, i'm pretty sure i won't be changing your point of view.

> wonder if a study may exist that shows the economic benefits of Airbnb in communities, keeping more of the income within local residents, patronage to a larger spread of local businesses, greater financial independence from self-employment etc...

I haven't really thought of that, but you also have to remember that this is Toronto (specifically near and around downtown) , and it is going to get tourists regardless of Airbnb. And what happens to local shops when a unit is vacant for 4-5 days a week?

Of course, but that's a much deeper issue. Today, we generally accept that in a free market without externalities, private profit = public good. If you disagree, you can take that up with Adam Smith and the invisible hand. ;)
That's quite the opposite of my experience where only very cold data is not SSD-level performance. Do you have anything like anti-virus software which might be interfering with the HSM mechanism?

Investment is not speculation. Its of course a game of definitions, but generally speaking both economists and financial literature separate them on their usefulness and advice.

Starting by the conclusion here. People also willingly spend money on the lottery, or betting, and although it has some entertaining value, it would be to the detriment of society as a whole if investment were diverted into the speculation of games of chance.

There’s a dimension to this that you’re not considering: what you care about most as a government is that no one else gets a lead on you (that is, relative advantage).

I can see how OP would come up with this - Angular w/Typescript is probably the "Microsoft Way" choice for front-end JS and has good support in VS.

> “OO essentially has "select" redefined every time you want to expose data.”

I still don’t see how this is different in concept, since you “redefine” selection every time for normalized attributes as well (you must individually hand-specify where to select from).

I get what you’re saying about polymorphism, such that things like select or join “just work” on everything. Many OO / functional programming languages have that too, for example with __getitem__ or __getattr__ protocols in Python, so that the same “verb” (e.g foo.x = 3) “just works” automatically without concern of specialized implementations.

But in the declarative case you’re just trading off the conplexity of creating and registering specific getter logic per each type against flattening out all the attributes such that all the complexity is embedded into knowing the correct name to ask for the universal verbs (e.g. select) to apply to.

ASK HN: Software Apprenticeship or Software Bootcamp?
TLDR;

On handing in my notice at work, my company offered me a pretty awesome opportunity to rotate into a web development position with complementary training courses and a mentor.

Since I'm simply trying to optimise my learning (and not my financials), do you think I'd learn more full-time at Lambda School (a 9-month bootcamp) or working in a sort of apprenticeship model at a company?

For some additional context, I'm currently enrolled in a part-time course in software engineering (covered C & Java), but have only built console applications (~1000 LOC) so far.

Ctrl+c is same as esc in vim.
I prefer CTRL to be where caps lock was. I use CTRL very often, especially since (on macOS and Linux) many text fields use readline, which means you get Emacs ctrl- movement keys.

Almost the only time I use ESC is in Vim, and ctrl-[ or ideally the jk/kj->ESC mapping is really nice for me.

Now that I go the jk/kj esc mapped for .ideavimrc, I'm super psyched.
There was an episode of CSI:Miami (I know, corny, hyperbolic, whatever, it raises a really salient point) I recall a line where Caine makes the point that we don't find evidence to support a narrative, we chase the evidence to find the truth.

Too many of the studies today are funded to look for evidence to support a narrative instead of chasing the evidence to find the truth. The former is propaganda. The latter is science.

When I say too many, I mean to say that there are enough that people are very very aware of this. This fact alone is a problem because it damages people's perception of what is going on in the scientific community. If people cannot trust scientists to deliver truth rather than deliver support for a narrative, we have a problem. Whether this perception is fair or not, it is so.

If perception is that we cannot trust the scientists delivering the test results, nor the providence of the testing, then how can we trust the information we're being shown?

People need to see integrity before they can trust anything else.
The Evolution and History of the Apple Logo Design and Meaning
I worked on a couple of production apps in Rails at the start of my career. It was the first way I learned to make web applications.

Rails works as advertised and is great at what it does, but I think ultimately the conventions-obsessed nature of the community, that is often so helpful, has settled on some patterns that make the Rails approach more bother than it's worth with other good options out there. Often touted for being able to scale business logic and developer productivity at the expense of runtime performance, I see some serious issues with the claimed strengths.

- The powerful active record pattern and accompanying library makes it easy to pile on coupling between business logic and database access code.

- Ruby doesn't give you a straightforward way to protect against mutation, which leads to some real debugging nightmares at the worst of times.

- Rails conventions openly disregard low hanging fruit best practices of OOP like the SRP, and make it difficult to design code that follow these practices without straying outside the well trodden conventions (hi again Active Record).

- Rails provides configuration-like interfaces that don't feel like you're calling Ruby code. They are convenient, but offload a big cognitive burden in the name of convenience whenever you need to problem solved something that's not a garden-variety bug.

Ultimately I made the time investment to try some other approaches and have been finding that it's possible to get much of the productivity of Rails at the (arguably worthwhile) cost of a bit of extra typing up front. If you know Ruby well already and have some business goals with some urgency behind them, certainly a great move. If you are earlier career and looking to invest in a productive skills set, you may be better served to consider a few different options.
I’ve been using Postico (https://eggerapps.at/postico) on OSX for the last few years and been enjoying it: clean look, ability to edit and explore schemas, ability to export results to a variety of formats (JSON, CSV, etc.), and good cadence with releases.

The main thing it can’t do well is export/import large databases but that’s what ‘pg_dump’ and friends are for.

Sometimes the natural gradient turns out to be easier to compute than the gradient, and then it has made it in to applications.

Variational Inference: A Review for Statisticians (Blei et al., 2016)
https://arxiv.org/abs/1601.00670

In this case, the gradient (51) has the Fisher Information in it and the natural gradient gets rid of that hard-to-compute term. This stuff has been used in a bunch of applications (section 5.1, p23).

You could argue that someone pragmatic might have tossed that positive definite term anyway (without knowing about natural gradients). Or come up with the same algorithm, as a heuristic improvement of existing algorithms. But the connection is quite neat.

> Education is about teaching children how to think, communicate, and act

CS is incredible to teach how to think. Algorithms, using logic to solve problems, decomposing a problem, etc... Theses are all skills that make you think, that push you to UNDERSTANDS better. Personally I never seen my college classes as nothing else than learning to learn, because that's computer science. More often than not, the lack of information given by the teacher wasn't a proof of incompetence but a way to test our capacity to search and discover by our self.

Sure I learned a bit in my french classes, sure I learned a bit in my history classes, but I never ever learned to think in any of theses classes except CS. I only learned to apply theses skills.

The longevity myths are well known, there are local myths of 100+ year old mountain men, (caucasus + some other range in south asia) and the myths of ancient "golden age" when people didn't age are almost universal, and many of the earliest written sources insist on "implausible" ages of certain people. Surprisingly many religions (virtually all, in fact) agree that people started aging when they previously were not and longevity was the normal state until aging was inflicted on people, only the reasoning why it happened varies. - all the abrahamic religions, a very important part of hinduism mentioned in many texts, the greek religion, sumerian, etc.

At the same time the US is 10 years behind. GDPR is far ahead of anything the US has.

In average I'd say the US is behind the curve and falling further by the day, especially now China has become a semi-great soon to be superpower.

> Someone in Asia is five times more likely to be using IE8 than someone in Oceania.

The above is based on 0.09% usage in Oceania vs 0.50% usage in Asia.

A bit off topic, but is that how statistics works? Like since the likelihood percentage is not on an absolute, unlimited scale but a relative scale I don't think it's meaningful to say that, is it?

I guess you can say that selecting a random person, you're 5 times more likely to pick an IE8 user in Asia than Oceania. But is it correct to say that a specific individual is 5 times more likely to use IE8?

I cant decide if there's a difference there, or if it's just a different way of saying the same thing.
