A bit off topic, but I recommend that anyone interested in this watch They Shall Not Grow Old (https://www.youtube.com/watch?v=IrabKK9Bhds) - it's an excellent documentary, a bit of a passion project by Peter Jackson to polish up a lot of old WW1 footage (normalized the frame rate, since it was hand cranked, colorize, and add sound - he hired lip readers and voice actors from the same regions as the filmed soldiers). It makes it seem much more relatable and real, in a way that comically-fast black and white footage really doesn't.

Reading the current Science article on this topic I got the impression that ‘quantum advantage’ might be a more reasonable first goal. that is we are still waiting for a quantum computer which can perform better than an ordinary computer in a single restricted setting.
Also I was a little bit shocked that even with 16 Qbit those systems already show a significant error rate (I think up to 50%)

My skepticism was confirmed by estimates in the same article of the Quantum supremacy still being decades away. So I’m a little bit confused about the current announcement but fortunately it is easily falsifiable... let’s wait for 2020

I understand that Docker's user namespace support is relative basic, but the point I was looking at was that if you don't run your contained process as root (e.g. unprivileged) by specifying a USER in the Dockerfile, then I wasn't aware of major differences in the security of an LXC container as against one running under runc

I'm not sure what you mean by "effectively" a PRNG, but the big objection here is the EPR paradox. A true RNG can be stateless, but a PRNG necessarily requires state. So where is that state?

It's not in the wavefunction, so we must introduce new axioms: non-local variables, or super-determinism, etc. Yuck!

The MWI program is eliminating the objectionable "part two" of QM: probabilistic measurements and wavefunction collapse. But it's no progress if the replacements are even worse!
Great article! I learned a lot about human decomposition, and I'm glad there's a facility out there doing this kind of research.

One nitpick: The author mentions a recent study claiming that cell phone use can cause bone spurs on an individual's head as an example of how quickly our bodies can change while we're still alive (vs what happens over generations and while decomposing):

> Changes in DNA can take generations to occur. By contrast, our skeletons can show widespread changes in as short as 10 years — from the bony protrusions now increasingly common on the back of our skulls (“text necks,” some are calling them) to our increasingly low bone density as we transition from manual labor to office work.

There have been serious deficiencies identified in the original study, from not actually measuring and providing data to back up their claims, studying the wrong thing, and did not have a random, representative sample. This doesn't detract from the main point of the article, but goes to show how easily an inaccurate study can permeate the societal knowledge without being corrected.

It isn't really very good for machine learning - machine learning doesn't need 8 bits of exponent.

For weights during training, 7 bits of mantissa also seems a bit low - it's common for weights to adjust much less than 1% during a single batch of training, which this couldn't represent.

I think this is more a "we want something which is faster but is compatible with existing code written for fp32's".

100 companies are responsible for ~70% of emissions. To argue that an ordinary person switching to reusable bags and an electric car will make a difference is (sadly) wishful thinking.

It's nice to feel in control, so I understand why you might want that story to be true -- but I'd suggest a better use of your energy would be political action. The only way this problem can be solved is through significant political action that is proportional to the climate catastrophe we are facing. Anything else is adjusting deckchairs on the Titanic.

Your analogy makes no sense by the way -- nobody was pouring buckets of water into the Titanic. The hull was breached -- there was a fundamental problem with the state of the ship. In fact, everyone getting pails and throwing water off the Titanic wouldn't have saved the ship or the people. Individual philanthropic action can't fix problems that an entire economic system has created.
so... I've never been really poor, but like most of us, I've had lower income and higher income. Everyone gets unexpected bills, but my experience has been that those bills don't get larger with your income (even though most of your expected bills do grow with income) - a lot of those unexpected bills get smaller in absolute terms as your income goes up; both cars and medical expenses, in my experience, tend to move from 'unexpected bill' to 'expected bill' as your income goes up, as you generally get much better health insurance and newer cars.

But even the things that don't move from unexpected to expected are harder to deal with when you are poor.

Example; person A makes $14K/yr at walmart. They put away 10% of that every month.
person B makes $200K/yr at Facebook. They put away 10% of that every month.

Say you get a $250 parking ticket.

If you are putting away 10% of your 14,000/yr salary - that parking ticket is gonna be a pretty big bite of your savings. I mean, if you've been putting away $1400 a year, you can cover it, but that $250 is still a big bite.

If you work at facebook... say you are still putting away 10% of your $200,000 salary - that parking ticket costs you just as much, but it is a whole order of magnitude smaller when compared to your savings rate.

Medical expenses are the more common case for unexpected bills; it's super expensive to get hurt while poor. It's not so expensive to get hurt while wealthy.

Say you are playing catch with your kid nephew and you fall and mess up your knee. If you make $14,000, you probably have health insurance with the maximum deductible, and end up having to pay a bunch out of pocket. the 2019 out of pocket limit for an ACA compliant HDHP plan is $6750 - that's going to take a lot of saving 10% to pay off. And even if you do get it fixed, you probably have a job where you have to stand up and carry things; you will need a bunch of time off, time off that you're not gonna get paid for.

Say the same things happens to the software engineer making $200K/yr. First, that job probably comes with pretty nice health insurance; you probably aren't out much out of pocket at all. The place where I work offers a HDHP plan but they actually give you an amount of money equal to the deductible every year. (me, I still take the traditional plan, 'cause I'm willing to pay extra if I don't have to deal with medical billing at all) Next? SWE jobs usually come with a bunch of paid time off. This person probably gets paid to recover at home. And if they felt like they needed to work? they probably could work from home; and for that matter, their job probably doesn't involve knees much, so they are gonna be able to go back in to work much sooner than the guy working at walmart.

My first programming job was for a defense contractor.
There was no PTO concept, just vacation (2 whole weeks a year) and sick leave (12 days a year). Unused sick leave accrued indefinitely but was not usable in any other way.

I was putting myself through University and still had about 2.5 years of work. I was taking 12-13 units at night year round. So, there were times when I'd use a sick day for study/project/etc time. But I was lead programmer on a critical system by then (including being on-call) and was my department's de facto liason to the computing center, so I got little friction about it.

True story-- the Nervana Maxwell stuff didn't go very far-- but it was noteworthy because they had both that small win as well as their own hardware platform.

One other thought about the Nervana-Xeon convergence is that the support for more memory (thru DDR, Optane, or even just mmap'ed NVME) will be a big win for modeling and large-minibatch SGD. For example, the minibatch fetching could be pushed to the hardware / OS instead of Tensorflow (or the crazy guy behind Tensorpack) using a threadpool. A lot of training is still I/O bound at some level, and processors only support so many PCI-e lanes...

This is cute. But the conclusion is wrong — we can actually generate as much energy as we are currently using directly from sunlight.

It’s not trivial — costs $1X trillions, covers lots of land (a 300-mile square!) and will take a long time. But then, we have more paved roads than we would need land covered by solar farms, so it’s not a completely ridiculous amount of space.

We don’t necessarily need to sacrifice lifestyle to use energy sustainably. We just need to stop burning fossil fuels pumped/mined from underground.
What are you using to vectorize avx512 for HMC? Do you have a lot of element wise ops on big arrays?

Conservatives always decry some group getting something for free, which is actually paid for by the taxpayer. Distributing non-recyclable plastic and forcing rate payers to pay to dump it, collect it from rivers and drains etc is it be such case.

A market mechanism uses the power of the market to encourage correct behavior through market forces, instead of penalties, taxes on all, special schemes to give cash to specific state controlled recycling projects, etc. A market mechanism allows free enterprise solutions, whereas 'social insanity' creates inflexible regulatory processes.

These fires substantially accelerate the melting of the permafrost, both by the primary heat of combustion, but also by secondary effects like soot. Permafrost stores about 1500 Gigatons of carbon. Humanity has released about 650 Gigatons of carbon in total so far.

Are memory-heavy applications able to detect true available memory? I could see an app that tries to scale itself to available memory running with reduced performance or refusing to run if it sees non-page-cache but evictable memory as unavailable.
Yes not everyone can run. I inevitably get shin splints because I have very flat feet. Barefoot running doesn’t help.
Gradient based algorithms are more efficient for large parameter spaces.

For second question, the discussion mentions that there are lots of non-differentiable parameters and they don't handle that.
The negotiation power comes from different moving costs. As a tenant, you have to spend time finding new space, you have to pay for a moving company, you may have to renovate either the rooms that you are leaving or the rooms into which you are moving. Additionally you may lose direct contact to neighbors you like. All landlords have to do is look for another tenant. As long as it is not a buyers market, that's not much effort.

Language is very much cultural, the instinct to communicate and decipher others utterances is what is inate. Otherwise one could automatically understand other languages without learning them.

Dolphins and whales are already communicating currently. But it's possible that what we are seeing now is a much simpler version of what existed previously, not to mention that we don't have any clue how to decipher what we are hearing now.
It depends on whether someone wants to make something of it. The costs taken into account by the CFAA include the costs of investigating the incident and repairing any damage, and courts in the past have tended to accept pretty much any assertions about these costs. They probably wouldn't blink if the entire cost of fixing the exploit were attributed to the OP.
Where are you, partner? The trail is waiting
>As long as your income is not at the lower end of the distribution

I think this is key. If you make $200K/yr, saving 1/10th that means you drive a lexus and not a benz. The Lexus is not worse than the Benz in any objective way; you paid less and got a car that is going to be more reliable and cost less when it does break. I mean, don't get me wrong, I like how the german cars drive, but you've gotta be really dedicated to own one out of warranty.

The problem is that sure, at a high income, you can usually save a lot of money by making sacrifices that are merely aesthetic, by buying goods that are objectively no worse (and sometimes objectively better) - but below a certain point, buying a cheaper good is going to get you something objectively worse; often something that will end up costing more in the long term. Downgrading from a 15 year old Toyota to a 25 year old ford is going to get you something that probably costs you more, in total, to operate, even though the initial purchase price will be lower.

I mean, I think the disagreement here is mostly at what level this happens.
They have compromised crypto standards in the past, but we can't use that to justify every conspiracy theory without evidence.
I think there is also a problem with too much documentation. If you want do document too much, the docs will get too tedious to read and crucial information can be missed.
You think a frigging moon base won't be subject to every single one of those problems and a hundred more besides?
The thing everyone appears to be missing is that you don't need land lords. They don't produce anything anyone needs.

The point of the whole mechanism is to force out less wealthy people and/or with smaller income and replace them with more wealthy ones and/or ones with more income.

If this is a nice thing to do or desirable aside, there are better formulas to accomplish the same. You could for example tax housing heavily then burn the money on live tv. That way you will at least have the advantage of configuring how wealthy the citizens need to be.
Why the wheels fell off China’s tech boom

What does this have to do with anything related to HackerNews? Go fuck yourself.
My take here is that we lack universal tools for working at higher levels. The only thing we’ve managed to standardize on is ASCII/UTF

What we need is a standardized representation for tree structures and their schemas. XML is too complex. JSON and YAML isn’t good enough. Lisp is pretty good, but I think the text representation is off-putting for a lot of people and its general focus is not quite in the right direction (recursive lists of data/items rather than having typed nodes that contained list of other typed nodes, like XML, with schemas defining every node type)
Yes very nice theories he came up with and very sad to live in a world that's like the dirty, bloody, stained picture of this utopia.

We endure the current situation because of the greed and narcissism of a few who don't want to share. I suppose it was their parents and kindergartners who did a really lousy job showing them how to share and collaborate with others.

Why should they care if people have to starve when they could have a new yacht, beach house or another 50 motorbikes in their garage?

You are over complicating.

In general applications don't manage their ram usage based on available resources they just take what they need until your system starts swapping.

The OS manages memory and evicts cache to make use for applications when they request it. The good thing about a cached file is that it is available on disk to be reread any time you like.
