It doesn't list all of the ETFs that are more volatile but the one they do list is a leveraged ETF. I would imagine most of the other 59 are as well. These leveraged ETFs are specifically designed to be multiple times more volatile than the market they represent. They are meant for traders to speculate on movement of the markets and no sane person would hold them for any extended period of time. A Bitcoin ETF being more stable than them is not an accomplishment and anyone saying as much is showing a complete misunderstanding of the goals of those two investment vehicles.
I don't understand how your response addresses the question asked. I don't understand your hetero white men comment either. I would argue that Facebook and its ilk are destroying the ability to keep a private life (nevermind "harassment at scale"), and that's uniformly true for minorities as well as majorities.

Good answer about ads though. And working in this business seems more morally defensible than working in the defence sector, although the more you think about it the less that holds up. (and Google is definitely not Facebook, which works to normalize the panopticon existence)

I'm not sure if it is still true on Win 10, but earlier versions started to perform terribly if you had no swap on the boot partition, regardless of how much core you had.

This reads like a general lament about the world at large declining.
It's instructive to diff the hexdumps of the two files. It's surprisingly small.
> on Windows 98 it just started swapping, but it was no big deal.

At that time, swapping out a 4k page was a significant part of memory: 4k of 16 MiB is 1/4096 of memory. Each swap gets back a lot of memory the program needs. Now the swap is still 4k pages, but memory has expanded by a thousand fold. Basically swap is a thousand times worse today than it was in the time of Windows 98.

For harddrives swap isn't used now to expand memory, it's used to remove initialization code and other 'dead' memory. Swap should be set to only a tiny fraction of the memory size for this reason, to prevent it from being used to handle actual out-of-memory conditions. But realistically for most users it's not even worth enabling at all because of the occasional memory that needs to be swapped in from disk.

For SSDs the seek speed has improved to match the extra memory so swap can still be used like in the old days to expand the effective memory size. But memory is so large a swap file that's a fraction of memory size to offload 'dead' memory is enough unless there's a specific reason to actually use swap for out-of-memory.
Setup the 401k. When you leave, go to Vanguard, set up an account with them and have your 401k rolled over into your Vanguard account.

From here on out, every time you change jobs, request a 401k rollover into your Vanguard IRA. This way, you'll only ever have two retirement accounts to deal with, rather than one for each job.
That's a form of name-calling, which we've asked you repeatedly not to do here. If you keep doing it, we will ban you.
We reached this same conclusion for our servers generally. The problem with swap is that it's unpredictable. It's better most of the time to have a system that's predictable. However much RAM is available to the system, you can deal with that, by making an appropriate choice of hardware type, or by scaling up, tuning software, etc. It's harder to deal with performance problems related to use of swap in my experience, since it's nondeterministic what will be swapped.
The rise of renewables at the expense of fossil is also a tale of technological unemployment across mining, power, and even transportation sectors.

Coal plants, particularly the older ones most at risk of closure in the US, require significantly more labor per MWh generated than cleaner sources.

Here's a recently announced coal plant closure:
http://www.cortezjournal.com/article/20161001/News05/1610099...

...

the local job options could be pretty limited in far-western Montrose County once two of its major employers close their doors, eliminating what are currently 55 jobs at the plant and 28 at the mine.

...

According to the EIA, the Nucla plant generated 416,150 MWh in 2015 for an average annual power of 47.5 megawatts: http://www.eia.gov/electricity/data/browser/#/plant/527 That's an abysmal productivity per employee (or a fabulous job source, depending on your perspective): 0.86 real annualized megawatts per employee at the plant ; 0.57 megawatts per employee if you include the mining jobs.

A well-sited utility scale solar farm like Desert Sunlight can produce an average annualized power of 147 megawatts with just 15 full time employees, for a ratio of 9.8 megawatts per plant employee.

The construction of renewable energy systems still consumes fossil fuels as inputs to manufacturing concrete, glass, metals, plastics, and silicon. Construction machinery likewise still runs on fossils. But the lifetime-amortized dependence on extractive industries for a MWh of renewable energy is much lower than for fossil energy.

In the recent past, coal made up 30% of all dry bulk shipping: http://marketrealist.com/2014/01/key-players-involved-global...

In the USA, coal is the single greatest railroad transport category by tonnage. From 2008-2012, when volumes were considerably higher, coal was an even greater #1 by tonnage and was also the #1 source of railroad revenue:

https://www.aar.org/BackgroundPapers/Railroads%20and%20Coal....

There's no commodity that has enough volume to make up for the decline of coal transportation. There's going to be "stranded assets" left in railroads and shipping along with fossil extraction.

And, coming with the rise of electric vehicles, trucking jobs on the chopping block too. Hazmat certified tanker truck drivers -- the ones who drive tankers carrying flammable fluids -- are highly paid, well above trucking jobs in general:

http://www.truckdriverssalary.com/tanker-trucking-salary/

https://qz.com/24388/how-to-earn-170000-a-year-driving-a-tru...

Their ranks will dwindle if/when electric vehicles suppress demand for refueling with fluid fuels. Even if self-driving trucks never pan out.
Most of the people around me are using it as a speculative investment / store of value. If my sample is not biased and this is the case for the whole universe, that alone should be driving the price up.

The amount of new bitcoins that are being made available is just 12.5 every 10 minutes, this is a mere 1,800 BTC a day, or around USD 2 million. If the main use for bitcoin is store of value or long investments, the available "old" bitcoins are not going to be that many. In my opinion this is the main driver of the price.
The whole "main" page being under 2kB is an adventurous thing indeed. Overall, interesting implementation and incredibly clean layout (CSS is 541b.)

What languages are the site written in?
First employee of a major exchange here. High BTC values and regulatory acceptance are good for the crypto-currency sector as a whole. Bitcoin's persent-era limitations are well documented, and these do not affect market capitalization, maturity and the availability of conventional asset exchange infrastructure which are all critical factors in large-scale adoption. Major exchanges that have added ETH essentially represent a de-facto recognition that BTC is not the "one true solution", and that's fine. No system is all things to all people. In heterogeneity lies strength.
Redox Flow Batteries can be expanded by also just adding more "pressure vessels" to store the charged electrolyte.

Which is why I'm more interested in Redox Flow than Lithium Ion, for grid-scale applications anyway. Lithium Ion's efficiency is necessary for cars or other mobile applications. But if you're building it on the ground, you just build a bunch of cheap heavy tanks all over the place.
I would agree with you that SpaceX is more meaningful than advertising but advertising is not always a zero-sum game. In the Pepsi vs Coke case or Ford vs Toyota then yes it is a zero-sum game (unless you consider the increased competition a benefit). But in different cases online advertising allows some services to exist that would otherwise be impossible.

One example is that you can be a self-employed bookbinder in a remote town by advertising your services online. This allows you to find customers who want your services that you would not otherwise be able to find. Those customers are able to find more bookbinders than would be possible without online advertising which drives down price.*

So, online advertising is not always zero-sum, it allows some business that would not be able exist without it. The existence of more businesses reduces price for customers.

* I got this idea from an article I read previously and am not able to find.
Have you not written:

"I also do not recommend using a centralized service that keeps your keys on a smartphone. However I warmly recommend using the Signal Protocol whenever messaging is to be done. Signal can be a direct replacement for PGP someone just has to code up the whole thing (time to flesh out signal-cli)."

Can be, someone just.
Anyone can try it today :)

I'd love to see your findings, I'm curious as well!
To get good data it either needs to be either indisputable or non-controversial. Murders (as a statstic) are controversial but indisputable.

But shootings are controversial and disputable. I suspect the numbers will be politicized and manipulated until they are no longer a good measure.
There does seem to be room for someone to swoop in and become the more obvious managed ghost hosting provider.

The code itself appears to have a very liberal license, so no issues there, even if you to want to extend some things to allow better multi-tenant support and don't want to release your code.

And there is some obvious value add in someone that can simplify things like https setup, version upgrades, security patches, and the like.
> Steven Galson [...] has called the strengthened approval process created in 1962 the FDA’s “biggest contribution to health.” Before that, he said, “many marketed drugs were ineffective for their labeled uses.”

Sam Peltzman in "Regulation of Pharmaceutical Innovation" provides statistical evidence that the "safe and effective" 1962 Amendments reduced the development of new effective treatments as well as new ineffective ones, for a net decrease in positive results.
I'm seeing pushes to do this, and promises of that, but this is all stuff that should have been there from the beginning. The Preview window still stumbles on views imported from the Support Library, the emulator is a little better but still not great, Instant Run is a disaster, and Constraint Layout just now came out of beta.
The reason why meta studies get done is precisely because individual studies aren't reliable.
Combatribes is also an amazing game. In so many ways, it was better and more complex than Final Fight. Aso, the same complexity, make you feel you don't much control at sometimes, well, same happens on Final Fight, but then you have the desperation move.
100% on the 8GB thing. I have been wanting to contribute to a free Android app that I use heavily, but on my 4GB home machine, I can't even compile it, much less run the emulator at the same time. I realize that's a low end machine, but seriously.
Sorry, I didn't make that very clear - I meant that I completely agree!
Signal is for text messaging and fails as an email replacement. It also does not work for signing code and it requires you give over your contacts list to a third party to work.

Signal is not fit for PGP's use case.
Ethereum's currency (ether) is not finite and is predicted to not hold value like bitcoin. Ether is needed to power smart contracts not built to hold value.

Bitcoin wants to be digital gold, ether wants to be digital oil that is used to power smart contracts. This is a good way to explain it to the average person.
Reading the case at hand, there is a complication. The issue here is that the crime happened when all involved lived in the USA. The perpetrators have since moved abroad and therefore live outside of the USA. There is no question that at the time the crime happened, the warrant would have been reasonable and valid. The question is whether the warrant is reasonable and valid now.

Apparently Google has moved the data abroad so it is no longer on US servers. Google regularly does this - they try to place information close to where it gets requested for reasons of efficiency. On the other hand this fact is something that nobody outside of Google can verify. Are we sure that there are no copies left in the USA? Did you look in your backups? Are you sure?

So on a physical analogy, it is like a warrant for documents that were purportedly carried out of the country. If they really were, then you would appropriately have to deal with that other country. If they weren't, then Google should produce the documents.

The court doesn't want to debate Google on unverifiable facts. The crime took place in the USA. Google can easily produce the documents. We only have Google's word that this requires accessing data from abroad.

I can make arguments for this on both sides.
So for those us that need to run Windows/OSX to run software, like Photoshop, for our job, we should just give up on PGP? Seems like a supporting argument for the article then.
>This way, you'll only ever have two retirement accounts to deal with, rather than one for each job.

And due to how most accounts have a flat [annual] fee, you'll likely pay less in fees.
I wonder how much work the government could reasonably crowdsource.

> We hope to also support GPLv3 for a project, but the weirdness of not having copyright makes that a little more difficult.

Are they meaning strong copyleft here? I thought maintaining and using copyright law to enforce copyleft provisions was a key idea of the GPL?

Yes, but prescriptions do. Anyone can "recommend" vicodin right now, but it's hard to get some without a prescription from a real licensed doctor.
Yes, it is also your data they train their AI on. For free.

What you get back is more relevant ads err content err you stay longer attached to the ad screen err to your phone.
Yes, this is well known among working scientists. Even in my theoretical field it was well known that at least 50% articles contain some mistake.
This is a classic. After more than a decade in the bowels of the Fortune 500, this rings as true today as ever. I try and re-read every couple of years to refresh my memory.

One additional thing I'll add: Over the years it's become clear to me that the big ball of mud is not necessarily the worst end state. It means the code was valuable enough to maintain, and important enough to continue to extend.

While these are simple tricks almost everyone here knows, there are great books on advanced techniques. I heard about this one from a math blog and got it. Goes into gory detail about to manually calculate logs and roots, reciprocals and transcendentals. It was a fascinating read, I expected it to help me sleep at night and it did the opposite.

This sounds awfully close to "don't worry if you have nothing to hide". How about this; I'll create whatever steamy emails I feel like, and I'll use services that preserve my privacy while I do it.
In years when I stay with my current company, I barely get a COLA raise of around 2%. When I switch companies, even involuntarily, I can often get an immediate 10% to 20% gain over my previous pay.

This tells me that my employers do not look at current market rates when adjusting employee pay rates.

There are detailed survey data regarding actuary pay scales at https://www.dwsimpson.com/salary . It looks like they start lower than software pros, but grow faster and top out higher (everywhere outside of Silicon Valley).
In the words of an Android team member I talked to recently, "You use Windows??"
This is contrary to my experience in Windows 7. As under Linux, I run Win7 without swap on modern hardware, and I've had no trouble there. Which versions of Windows have you had trouble with?
The differences are confined to two SHA-1 input blocks of 64 bytes each. The first block introduces a carefully-crafted set of bit differences in the intermediate hash value (IHV), which are then eliminated in the second block. After the IHVs synchronize, all future blocks can be identical because SHA-1 can be trivially length-extended.
I understood the question – and that IntelliJ has all of those things is exactly the point I was trying to make.

You get most of the features from a heavyweight IDE, but they managed to get the architecture incredibly lightweight so you can use it as a "daily driver" editor as well.

It is snappy enough to quickly edit some configuration or Markdown files (with live preview and clickable links), it has text based configuration files, its easy to write plugins with a couple of lines of code – and all sorts of other things that previously could only be found on the "editor-side" of the spectrum (export VISUAL="code -w", anyone?).

Unique selling points are quite hard to find, most things where invented somewhere else. Its more the combination of things and walking the thin line between the text editor and IDE worlds.

I was a bit surprised to see this because I thought there might be more constraints on it, but I tried adding arbitrary strings to the end of both PDFs and re-hashing, and the hashes continue to be the same after appending arbitrary arbitrary-length strings. I guess this is indeed a consequence of the length-extension attack; we can argue that if -- for this kind of hash -- H(X∥Y) always depends only on H(X), len(X), and Y, then if len(a) = len(b) and H(a) = H(b), H(a∥Y) must also equal H(b∥Y).

Which specific thyroid organization sues doctors to force treatment? That seems highly unlikely. Refusal to provide treatment doesn't constitute malpractice.
I think many people are finding cross-border transactions to be the big draw for Bitcoin, especially in places like Venezuela. Ordinary people are using cryptocurrency to skirt government-imposed monetary controls. They don't care about the privacy angle and aren't trying to obtain illegal / harmful products.
Also the difference between identical and chosen prefix attacks too (this attack is identical prefix).

And you think it's easier to just pack up and move to Mars than to deal with the climate change? You think it'd be easier to figure out how to grow food on Mars than to mitigate climate change-caused problems with the food chain here?

There's lots of stuff you can do to grow food here even with climate change: greenhouses, indoor/vertical farming, etc. Good luck with all that on Mars.
I thought pretty much the same thing as I was reading this.

I don't think of these as "tricks", just "how I do it in my head".
I believe articles like this should get more attention. There is a lot of hype about new technologies around JavaScript, but also there are many successful brownfield projects still actively developed. They may benefit from the new technologies, but rewrite is rarely a good idea, and there are not much info on migration process (speaking from personal experience).
Very good points. My own bias is to believe the claims of the scientific community and is thoroughly revealed in my language. Perhaps I'm the one being bilked.
Brute-forcing bitcoin addresses is not in "economically senseless" category. It's in "even if every atom in the universe were part of a CPU..."
The practical guide to having a remote company
I'm not a mathematician or physicist, but (after a bit of googling) I do find some material that advances coordinate-free approaches as a kind of ethical discipline. Relations, understood as ordered pairs, for example, don't have a "natural order", we should mentally maintain the symmetry and absence of priority between statements like "the cat sat on the mat" and "the mat was sat on by the cat".

There's always, in discourse, an origin--a speaker. We can't escape that (see e.g. the linguistic notion of deixis) I think the article risked patronizing the non-hard sciences by assuming that they couldn't see that, being somehow blind to objectivity. Pretty dangerous territory.
Astroturfing like this, shilling and manipulating discussion, has gotten so advanced that it's almost impossible to tell real opinions from fake anymore. On the internet, nobody knows you're a dog[0]. I don't see any way to sort authentic comments from in-authentic ones. My conclusion has been to assume that any major conversation about companies/brands/products/governments on Reddit is probably astroturfed to some extent. HN "growth hackers" probably do the same thing.

This is a real problem, how to sort real users from the fake ones, and I'm not sure there is even a solution. But the integrity of our discourse, politics, and direction as a society is dependent upon finding a solution.

Your argument comes down to the threat model. A journalist whom also uses Photoshop is free to use whatever system they have sufficient trust in for the nature of the communication at hand.

If they're likely to be killed because someone reads the content of their messages, they should easily be able to weigh that cost against needing to boot of USB every now and again.

So that said, if you use crypto-system X on a machine you cannot trust, crypt-system X will not be able to protect you very much.
i3 is magnificent. The same display seems 10x bigger when using i3. As true for netbooks as for big desktops. My old x120 dual boots win7, which is unusably slow and unstable on it. Arch with i3 is still snappy. Unless I'm running a web browser. Web browsers have gone insane.
