In statistics you often think about having a "space of possible states of the world" and then seeking the point in that space which is in best concordance with the data you observe.

[For instance, we might assume that a basketball player's score in a game is a linear function of the number of shots they make. The possible states of the world are the multiplicative factors (points scored)/(shots made). This space is simple: it's just a line, probably even just a ray since negative points are impossible.]

One major trick is in the "seeking". To do so we often assume that the space is parameterizable like that it has latitude and longitude and then we scan over all possible choices of parameters looking for the parameters of the optimal point. Depending on the kind of model of the world you're working with, these parameterizations change.

[In the running example, the space is a line and the actual assignment of positive numbers along that line is a suitable parameterization. Higher dimensional models or curved models make parameterization tougher.]

Information geometry uses the tools of differential geometry, the same ones used to characterize general relativity in physics, to characterize this "state of the world" space more completely. It provides new tools for parameterization and understanding when older parameterization tools failed.

[In the running example we don't much need differential geometry to understand the geometry of our ray. In high dimensions, models with interactions, curvature, with discrete and continuous parts, intuition breaks down.]

It also provides a rich geometric vocabulary useful for visualizing the "state of the world" space which can be instrumental in understanding statistics, building new models, evaluating how models compare with one another.

This is the coolest thing I've seen in a long long time. If I remember correctly Microsoft released something similar for Windows Phone but the UI was really clunky. This version (?) is amazing though, so much better.

I've just spent 10 minutes playing around and building a simple app sat on my sofa, I highly recommend spending a little bit of time using this.

Cloudways provide three cloud infrastructure providers to host applications. We asked our point of contact with Amazon AWS, Google Compute Engine and DigitalOcean and here is what they respond.

DigitalOcean (DO): Being Patched. (The DO staff are busy in rolling out security updates. The patch will automatically be applied on DO servers inside Cloudways Platform.)

Amazon Web Service: Officially confirmed to be Safe.

Google Compute Engine: Officially confirmed to be Safe. (A Google representative informed Cloudways, “Google Cloud Platform was never vulnerable to this flaw. We do not use the vulnerable software.”)

Microsoft published a research paper about this technology before the Instagram app was released. I believe the Instagram app was a hack week project developed based on the MS research paper.
Just following up on this, I heard a report on the radio about "banking deserts" where there are no local bank branches for sometimes miles around in poor parts of cities. For people without a car, that's going to make banking pretty tough.

If you're effectively criminalizing large amounts of cash, and poor people are likely not to have a local bank branch, then you're almost criminalizing savings by people in poor communities.
It's the same project that was released for Windows Phone 7. The original name was TouchStudio. It became TouchDevelop around the time Windows Phone 8 came out, IIR.
That's just nature making the best it can of a historical accident.

If you were designing the eye from scratch, you'd have the nerves coming out the back like in squid. Then if you wanted something that concentrates the red and green wavelengths, you could put something else in front of the light sensing cells.

You'd end up exactly where you are now, except you'd not have a huge blind spot, and wouldn't have to spend as much brain power compensating for it.

That seems to address a subtlety about the layers of the retina, unrelated to the (bigger) problem of the optic nerve unnecessarily punching through the retina, leaving a blind spot that can't pick up light.

This feature/bug is absent in cephalids with no corresponding downside.

The human optic nerve structure makes more sense as being an artifact of path dependence and the "local improvement constraint" than it being (more) globally optimal in design space.
I have a cochlear implant; the external headpiece has neodymium magnets in it. Sometimes when it starts raining suddenly, I toss the external bit into my pocket or my messenger bag to keep it from getting soaked (and losing my hearing).

What I'm getting at is that the magnets have ruined my credit/debit cards several times, so I wouldn't consider this a "myth" at all.

Years ago I worked with someone whose father hunted/poached alligators in the south for a living. My friend was made to go into the water to retrieve the gators. I heard this story often enough that I 100% believe it. (My version of this: my Dad had me every month clean the bottom of his large sailboat in San Francisco Bay when I was a kid. The water was really cold, but no alligators :-) And, I got SCUBA gear for doing the boat cleaning.)

EconTalk has a great episode on this.

"ryan Caplan of George Mason University and blogger at EconLog talks to EconTalk host Russ Roberts about the value of a college education. Caplan argues that the extra amount that college graduates earn relative to high school graduates is misleading as a guide for attending college--it ignores the fact that a sizable number of students don't graduate and never earn that extra money. Caplan argues that the monetary benefits of a college education have a large signaling component rather than representing the value of the knowledge that's learned. Caplan closes by arguing that the subsidies to education should be reduced rather than increased."

I'm probably dumping Chrome soon too. What gets me is the random crashing. I can count on Chrome to still be running maybe 50% of the time when I re-open my Macbook in the morning.

Note to Chrome engineers... stability is a must-have feature, not a nice-to-have. Being a good battery citizen is a must-have. Performance is a must-have.
Thalmic Labs Launches Myo for Presentations
> Maybe something like Vivaldi, which builds on top of Chrome’s rendering engine, could be the answer?

Not likely if the main complaint is power usage. The browser engine is likely to be the main driver there, and switching skins won't help, especially for an engine as tightly coupled to its shell as Blink is.
I've been trying to piece this field apart for a while now, so here's my take on this:
Each manifold is just a collection of points that can be locally mapped to some coordinate system. Furthermore, distances between points can be characterized by a given metric and paths across these points define tangent spaces of valid directional derivatives.

But that's not as important as the idea that the points composing the manifolds in question represent distinct probability distributions. For example, 2D surface could be made that represents all normal distributions. One dimension is the 1st parameter (mean over all reals) and the second is the 2nd parameter (variance over pos reals).

This let's you think about quantifiably describing the differences between probability distributions of a given parameterization. It's cool and way more complicated than what I've described here. Check it out! Go slow and write out the definitions as you go along.

Med schools are a particular problem because the pipeline that starts with them is constricted by the number of residents the society/government is willing and able to support ( https://en.wikipedia.org/wiki/Residency_(medicine) ). So as long as it's an attractive field (getting much less so in the US) there will be significantly more med school applicants than slots.
Here's some info about the language used:

If this was able to achieve any arbitrary number score or even if it was able to consecutively hit scores beyond what a decent player could get, I would agree. But just because playing random works somewhat doesn't make it bad. I'm sure there are new players who would lose in Go to a computer that only placed pieces randomly in valid positions. But with a little skill, another player (or designed algorithm) should be able to almost always beat such the random algorithm.
It's funny how there's still a considered-harmful goto buried in the language, even though they don't call it that.

that would be a great idea, but I've had some seizures. I have some reason to believe that I won't have them anymore but before I drive I want a neurologist to tell me it's safe.

Oddly I can have a seizure while driving a car without anyone noticing. Several years passed before I was diagnosed. The first seizure that I know about, it was as if the entire universe sprung into being instantaneously, with me at the wheel of my car, in a driving snowstorm on a twisty mountain road, and no clue as to how I got there.
I'd recommend checking out https://cipherli.st for practical information on ciphers. It's quite easy to achieve an A+ by following their recommendations, once you understand the impact some of the changes might have (eg, using HSTS).

Completely disagree with this.

- Most sites contain static content and are not interactive. Things like simple forms don't really count, in my opinion.
- Sites which load static content are in my experience slower as a result of using AJAX, not faster

In fact, I'd argue that there is essentially no additional cost in building a site that uses progressive enhancement for loading content. If anything, my experience is it encourages a much more sensible architecture.

Of course, the value proposition changes when we're looking at interactive web apps, and I agree it's not clear that there's value there.

It doesn't have to be "enterprise." It's any conference with a demo alley and/or sales booths.

As others mentioned and only if you're forced to walk the gauntlet, remember to use an email alias (or email+tag) and a non-important phone #. Each scan gets your name, email and phone #.

If you don't tread cautiously, you get an army of sales drones calling you for the next year at all times during the day in addition to a never-ending, unfilterable drove of sales emails clogging your inbox.
TL;DR: IPv4 and IPv6 routing topologies of the internet are different. Especially of note is that AS6939 (Hurricane Electric, who also offer free IPv6 tunnels and generally do a lot to help IPv6 adoption) peers with A LOT of networks and thus sits in the "core" of IPv6 internet, connecting many networks on relatively short paths.
How is it a myth that magnets can erase magnetic stripes?
In my mind the trick is always in training models as it amounts to picking an optimal probability distribution from your manifold. Even in relatively simple mathematical statistics we quickly encounter curvature in exponential families but the tools to handle it are ad hoc. Differential geometry provides exactly the right tools to both talk about curvature and to talk about traversing the manifold and that is an appropriate place to talk about maximization as is needed.

How to Feel Attractive in Front of Someone New
When are we going to get over the idea of turning off javascript? No one asks "why doesn't my Java app run properly when I turn off the JVM?" I would argue that the open web is getting to that point with javascript.

JS is an open standard, highly performant, and implemented well by almost every single browser out there. The only people I know who regularly browse without JS are old-timers who got into the habit 10 years ago, before Spidermonkey, V8, Nitro, JavascriptCore etc. revolutionized performance, and before AJAX revolutionized architectures.

Let me propose a different way of looking at things. The concerns you actually expressed are performance, download size, and CLI browser compatibility.

Performance - I don't know of a reason that javascript apps cannot be performant enough, even on low-bandwidth connections. AJAX was invented to improve performance over static websites, by reducing network traffic to just the bits that change with each user action.

Download size - Javascript obviously has nothing to do with how many images or videos a site embeds.

CLI browser - Why can't the CLI browsers implement a javascript engine, and then render the results, just like any other browser? There is nothing about JS that requires a GUI.

Steven Novella, of the Skeptics Guide, responded to that research in a way that made sense to me: http://www.theskepticsguide.org/scientists-propose-incorrect...

Basically, just because we found some mechanism which compensates for the arrangement does not mean that we found the cause for the arrangement. The cause is more likely to be an evolutionary local maximum.
Credit cards are "robust" if they have a chip inside, since the stripe is irrelevant in chip transactions.

I wouldn't be confident in the face of a neodymium fridge magnet being rubbed across the mag stripe of a credit card.
Facebook instant articles is maybe great for users, but it's sad for the web. It will load articles much faster, but will create a more fragmented kind of web.

But then again the web of the future may not be just a few general purpose web browsers? Maybe we'll see an even larger myriad of special purpose "browsers" for various types of content like news articles. Many apps are like small special purpose browsers made to display data from just one site. The problem is that users have to have the app permanently using storage space on the phone. I wish there was mobile browsers that managed to store the javascript and static assets more permanently than browsers do now, but not too permanent.
I live in an apartment next door to an AirBnB in Manhattan. It seems to only get rented out for big, noisy parties.
SEO is my first thought. Have you ever tried to write a web spider from scratch? The various ways that websites are built can make scraping meaningful data VERY difficult. I recall one particular site that didn't even store the price for an item in the same parent container, so there was nothing (from a markup standpoint) that linked the product and its price... you HAD to view it with JS enabled.

I think down deep, the author is looking for the web to go back to the http://www.csszengarden.com days. I really wish web designers would put forth the effort.
It was actually based on a previous app (Luma) that did the same thing for several years prior. Instagram acquired Luma back in 2013.

I never did switch to Chrome or Chromium, simply because it doesn't integrate as well with the XFCE desktop compared to Firefox/Iceweasel. So maybe I don't know what I'm missing. Regarding the author's comment, "The problem is that the Web is now optimized for Chrome users and that means alternatives often provide a terrible experience." What are some examples of sites that provide a terrible experience to non-Chrome users?
