We need to distinguish between sea ice (a ~1m thick layer of frozen seawater), and land ice (up to 3000m thick layer of compacted snow). Sea ice is quick to respond to climate change (because it's so thin), and has a large seasonal component to its extent. Land ice is much slower to respond, and harder to replace once it's gone.

Antarctic sea ice extent has been increasing, largely because of a change in wind patterns. Winds blow ice away from the coast, leading to more open water, which leads to more sea ice formation. Even though Antarctica is getting warmer, it's still much too cold to melt sea ice in most places, so climate warming isn't having a huge direct effect on sea ice.

However, the land ice in the Antarctic is almost certainly decreasing (exact measurements are quite hard), and the trend is definitely towards more ice loss. Ice shelves, although floating, are the outer extremes of this land ice.

This is a good review paper on the subject of the mass balance of land ice: http://www.vliz.be/imisdocs/publications/248038.pdf
My team recently ganged up on me to tell me my line spacing was f*cked. Upon reflection, it seems that as I'm writing code I group lines into 'working well - one line, 'not sure - two lines', 'probably will change - lots of space', 'hey look at me! - off by itself'. Apparently, this unconcious invisible system drives others crazy. Developers are so picky! ;-)

We've actually got a bunch of automatic eslint rules, but it doesn't correct for this. Looking at the various beautifiers, I couldn't find anything that really cleaned up line spacing very well, and ended up running a bunch of sed commands to remove lines and then spacing out things manually in a "sane" way (so picky!!). Having a formatter that actually parsed the AST and rewrote the code like gofmt will be very handy if it works - I'll have to try it out.

Depends on the developers you talk to.

As someone whose Windows dev experience goes back to Windows 3.0, I was thrilled with WinRT, having Visual C++ finally catching up with C++ Builder and .NET finally going properly native as it should have been since .NET 1.0.
CME Group to launch blockchain-based instrument mid-2017
For me it was before Windows 10 WSL, but for my colleague it was after. It was very early on right after it was announced, of course. He tried using the Ubuntu on Windows stuff to run a Nodejs app but ran into weird filesystem issues. We didn't have time to be one of the first to figure out why, so it was back to the Mac for him.

No, he was not paid by the customer, he was paid by Best Buy. The customer paid Best Buy, but the tech would still get the same paycheck if that customer had chosen a different repair shop. The repair tech is not incentivized in any way to show loyalty towards the customer unless their manager enforces it somehow. But as the article discusses, the manager, Meade, has accepted money from the FBI (and then lied about it, of course in a way that does not expose him legally).
This. Most of the times it was a honeypot service and backpage probably shut it down because of that.
Anyone who continues to use Windows 10 cares nothing about security nor privacy. You are essentially opting into an Orwellian society.
Hundreds of Colleges Saddling Students with Unaffordable Debt, Feds Say
Chances are they have a script that hits a couple different websites that represent different archetypes: light/heavy text, light/heavy images, light/heavy js, light/heavy ajax, flash, rendering, dependencies, fonts. Instead of using the cache dozens of times, they refetch the pages (which would must more closely represent someone surfing ye olde interwebs). Seems pretty reasonable to me.
While this is worth trying for the sheer coolness of it, I'm a bit skeptical about how it will perform. For FDM things are much weaker in the Z-direction than they are in the x-y plane.
I guess the way to benchmark browsing to get most realistic numbers would be to record normal browser behavior of a decently-sized sample of people (say 1000) and automatically repeat the behavior of a representative subsample (10-50 may be enough).

This would take forever and cost quite a lot of money, however, so the much more reasonable solution is to simply turn off the cache for everything.

I don't agree with Apple or Techcrunch that CR's methodology is wrong -- pretty much anyone would make that same decision because the alternative is too much work for too little reward.

> So Windows is out (for non .NET devs). That leaves us with what, Linux itself as the OS? Anyone who suggests doing this either hasn't done it before or has way too much time on their hands. I use macOS because I don't have time to hunt for drivers, trying to understand an obscure error discussed in a long forum thread or having all my software no longer work just because I updated a package.

Sounds like you either haven't done anything on linux or trying to spread FUD. Downloading a driver isn't rocket science. Especially if you're a developer...

Hey there - I totally hear you. This has been a challenge for many of my new year resolutions personally, and I think this is also a challenge for those who design and build products in health & fitness space.

We're all about tackling this challenge (thus the name 'Simple Habit!'). And we do this by making meditations as simple and accessible as possible. Try out the app and you may understand what I mean!

Users also have the ability to get daily reminders to meditate at a certain time of day, and this has been quite effective.
> Sex workers didn't suddenly become less vulnerable simply because they're posting Craigslist ads.

Actually, they did. With a red-light district you have to be there, exposed to the pimps, to be exposed to the customers. And the density allows pimps to control more people, enough to make the activity profitable.

With out-call services from ads you avoid the presence of the pimps in the first place, and the configuration (outcalls) makes capturing a sex-worker much harder if they try which makes the economics much less attractive. Pimping is a crime of opportunity and outcalls remove most of that.

Also, not being street-people, call-girls get much more respect from police if they need to report a crime.

Shadow Tactics – Rendering Breakdown
I'm curious to hear from current researchers:

Back when I did some work in neural networks (10-15 years ago), the field had become saturated with 'meta' papers on topology generation, and also on optimization techniques, (slightly better gradient descent, pruning techniques etc). Neural networks had become more art than science. At the end of that period, I got the distinct sense that these were signs that the field had stalled in any significant break throughs. Soon after they fell out favor for well known reasons.

I'm curious outside of the current hype, if there's a sense of that now with the current field practitioners and saturation of papers.
The awesome thing about meditation is that it involves no language, and is therefore internationalized, right out of the box!

I'm not belittling 'guided meditation', which I assume this app provides and may be a good first step for beginners interested in meditation - but if there's a voice coming out of a speaker giving you suggestions, you're not actually meditating at all.

I dunno here. CR's validation around the fact that users will often visit different sites seems on point to me.

Some users visit the same sites over and over, true. But, a more accurate browsing pattern would be different sites, new content etc.

A more in-depth detail on how the browsing is done (automation) might be relevant. If they hit the same 5 sites 1000 times vs. 1000 sites 5 times would alter whether they disable cache or not. I'd say the former makes sense, not the latter.
Reminds me of a very cool paper I heard about at ACM Dev 2014.

Depression seems to be caused by both external factors (such as crappy job) and internal thought processes (worrying too much, negative thoughts, etc) or a combination. And some people are just more prone to depression than others. In your case it sounds like some kind of CBT, ACT or mindfulness therapy might be helpful.

Hormones are well known to interact with the stress system and exacerbate depression.

You make a good point about depression itself causing issues with (for example) your job, making it difficult to know what is the source of the problem. I think the best that people can do in this situation is to take a break from work, and think carefully about what they really want from life.
Calculus, by James Stewart. I recommend you buy a dead tree copy of an old edition (I paid $5 for mine, shipped. I don't know how they made money off that sale.) Might not be the best book, but it covers everything you need to know, has good exercises, everyone uses it, you can find the solutions manual online, and the harder problems have an answer on stack overflow.

And some linear algebra book by Strang (as others have said.) I don't remember which one I learned from, but I do remember it was excellent.

I can't recommend a good stats/probability book. People recommend Statistical Inference by Casella and Berger, although I wasn't super impressed with it.

You'll also want a good understanding of set theory and proof writing. I don't remember what book I learned from, but try to find some introduction to math thought.

This is all assuming you have a good understanding of algebra. The above mentioned books require geometry/trig, but you don't actually need that for machine learning.
You could hack a diffing tool that reformats both the before and after and shows the diff of the generated text.

This would not catch changes like

--val x = [1]
++var x = [
++ 1,
++];

as expected, while it would give you a slightly more verbose diff if the change was

--val x = [short(), short()];
++val x = [
++ a_really_long_name_that_pushes_the_line_length(),
++ a_really_long_name_that_pushes_the_line_length(),
++];
There are more and less naïve ways of pursuing self-interest. Or maybe I should use the word greedy, because it's effectively a synonym here. Owning a bunch of cars (or hammers) so that you can use them whenever you need is one strategy; efficiently sharing them with everyone else so that there's always one available when you need it is another.

For fulfilling needs that most people have, sharing can indeed be a more efficient solution than owning - especially if the good itself is expensive to make (with "expensive" including also energy use and environmental impact).

Now, if you absolutely, positively need to own something because you like ownership itself, then that's a need sharing won't address - but that's a need society will always have to fight against in more extreme cases, because no matter how wealthy the world is, one can always invent something to own that's beyond the society's ability to provide sustainably to everyone.

I'd say if anything it's an even better argument in favor of decriminalization, which I feel is acceptable to many people who wouldn't favor full legalization. I think I prefer the latter, but even the former would be a great improvement (and, in my opinion, should apply to pretty much any drug).
My continuing commitment to my privacy means that I continue to stick with Windows 7, and only for those things that I must use Windows for. Everything else is done on Linux.

I acknowledge that this alone doesn't guarantee my privacy, but I refuse to make it easy for corporations to rifle through my personal documents and watch me like a hawk.

Aside from that, I object to having a "free" upgrade option shoved down my throat so often and aggressively that I've got to hack the registry to shut it up. It's clear that Microsoft still doesn't give a damn about what I want as a user.
Awesome! Just curious, which country are you based in? We can look into enabling it. The only concern for enabling in non-English speaking countries is that often users give 1 stars for not having meditations translated in their languages, and that's challenging to do so quickly for a small startup, as you might understand :)
Yep.

The joke is that Microsoft finally solved the perception problem around spyware by making the OS into one big bundle of spyware.

I still have a VM running Win7 that I use to run CNC software. Like any other software I don't trust, it isn't allowed talk to the net and any time it breaks I roll it back to a checkpoint and continue.

And that's all the Windows I need in my life. And now that Apple's laptops no longer appeal, the future, for me at least, is all about Linux and FreeBSD.
The resolution of the sensor is pretty irrelevant. Camera and subject motion, the MTF of the lens, and diffraction are much bigger factors (once you get to a certain point). You're almost diffraction limited on modern APS-C cameras at f/8! The motion of your hand and body will cause a point of light to illuminate two sensor elements even at 1/8000 shutter speed.

Basically, DSLRs require perfect conditions in the field to actually achieve the sharpness stated by the camera manufacturer. A 4x5 sensor allows much more slop.

The idea is nothing new..everything in machine learning is being automated. The hard problem is to find.the next step that can be easily...just randomly training new models and adjusting doesn't work, because training time goes up too fast.
> Having existential thoughts did not change the structure of your brain or alter its chemistry.

This seems like a really strong statement that can't possibly be absolutely true. Isn't there some literature on this?

I remember seeing some "self care twitter" posts with lists of things that "don't cure depression" (thinking happy thoughts, sunshine, Vitamin D) but obviously some of those do send it into remission in many people. Isn't that enough?
I include physical health in "going well". You clearly do too, hence "chemical imbalances in their brain". I think the problem is, we're trying to parse the world into discrete categories (this is a disease, this is not, this is an external factor, this is not), when the world is not really that easily parsable. All abstractions leak eventually.

Not even that, but forget America for a second and think china. Overloaded roads, horrible traffic and pollution, chaos, immature driving culture with a much higher accident rate, parking as an extremely scarce commodity, ride sharing/taxis already very common, and, most importantly, an authoritarian government who can change the rules overnight.

Driving actually doesn't suck that bad in the states, even in crowded cities like LA, but self driving cars could be transformative in a city like Beijing.

Thanks for the link. I read that, it seems to support my conclusion of this article as well. "As in, cultural differences can be expressed over time as genetic differences."

It seems like the debate we're having is a rehash of nature vs nurture, where it seems like the new research indicates nurture can affect nature for future generations through gene expression.
Websites change over time -- they'd have to download a static copy of the websites and store them locally for repeatable tests (but then it no longer reflects the real world, since websites often tailor themselves for each user).

And since browsing activity changes over time too, they'd have to regularly update the test, which means that tests are not comparable over time.
To be honest, it's equally difficult to have a serious discussion about science related to ethnicity when people insist on using an interesting piece of research as a launchpad to make tangential and evidence-free claims that social science is harming serious research, regardless of whether they actually harbour any sympathy for the viewpoints of your garden variety racist or not.

At the time of this article only two of the many subthreads related to this article had descended into politics and name-calling. One was initiated by your very own unsubstantiated attack on "identity politics". The other (considerably less favourably-received) post was claimed the notion of a social element to race that was the work of "lunatics and agitators seeking to attack and disrupt western society" and argued the researchers were doing themselves and society a disservice by engaging with it. Remind me who it was that's putting a negative slant on useful medical research again.
I think being able to draw would really make me happy but I just can't make it through those countless hours of deliberate practice I would need to put in before I can produce any worthwhile art.
Topology generation requires the evaluation of many models - For non-trivial datasets/model sizes the evaluation of a model can be hours, days or weeks, even on current GPUs.

There's much better tooling in place, and hardware in place( modern GPUs) now to distribute the evaluation over a cluster of GPU machines, so it's becoming practical to push the boundaries further

edit: I also forgot to mention, older methods often required the manual specification of heuristics for mutation and crossover rules, this is no longer the case, because the machines can be trained with objective functions to prevent overfitting, optimize execution speed or memory usage and can use techniques like dropout, skip connections, layer / node hyperparameters and so on to direct the topology search

It's funny, I was in Amsterdam this year and different from the experience of most of my international visitors, the whole place felt restrictive in terms of marijuana, not liberated. Denver, Portland, Seattle, Vancouver / Victoria (Canada) and parts of California now have what I believe to be much more liberal "marijuana cultures" than Amsterdam now. Vancouver literally has hundreds of marijuana dispensaries in its downtown even though pot is still technically illegal in Canada (for now.)

The Dutch coffeeshop model was cutting edge back in the 90's when no one else was doing it, but as you said it's incredibly outdated compared to the explosion of high quality dispensaries we are seeing across the Pacific coastal areas of Canada and the U.S.
I will note that one could design a pretty printer that reliably had better performance if the formatting style they chose was simpler and more amenable to it.

My (mostly self-imposed) task was more difficult because I was trying to follow the existing style that humans were hand-applying to their Dart code, and that had a lot of tricky non-local cases that look nice but are hard to automate.
