> The moment the transaction fees and block rewards go down, the very expensive Prof of Work mechanism will weaken and future transactions are unprotected.

Exactly.

One critical, related vulnerability that I haven't seen people discuss:

Right now, every new block gives miners about (12.5 new BTC + 3.5 BTC in fees) * $15,000 = $240,000

So miners are making a quarter million every ten minutes.

That incentivizes massive capital expenditure on mining hardware and massive electricity burn.

If the price drops significantly -- or Lightning Network etc solve the scale challenges, and transaction fees come down -- or in June 2020, when the block reward halves -- any combination of those may lead to a future where it's uneconomical to mine again, except in places where electricity is unnaturally cheap.

When that happens, tons of mining equipment will fall idle. The network difficulty will adjust down, and in the immediate term Bitcoin will continue as normal.

But now there's a big pool of latent hardware left over from the bubble, which can be activated at any time.

This may break assumptions about the cost of attack. If, say, a Chinese mining group owns tons of hardware that is no longer economical to operate continuously, there's nothing stopping them from shorting BTC and then doing a "spawn camp" repeated 51% attack.

(If you already own enough hardware, then such attacks are pretty cheap--you only have to burn tons of electricity a few times, for a few minutes each time.)
Show me the infinity He-3 and Mega-Billions in platinum I can make in an exclusive environment mankind is obligated to conquer on the timeline of a few short hundred years and I will show you some Multi-Billionaires willing to invest heavily as soon as the intersection of orbital access and autonomous robotics is potent enough to mine the crap our of that, and any other, 'Alaska'... Some imagine it will be many decades [never done those before!], until it's cost viable and some imagine 2020 or 2025 [0].

And I think my vision, and Elon Musks, has something more like autonomous driven lunar vehicles powered by machine learning and mesh networks for robust exploration. Like... 15 Teslas talking over wifi but with no traffic, no time limits, no pedestrians, no speed limits or laws against having jump rockets...

I totally agree we have to build PoCs, and test new equipment, and do science, and do engineering. But most of the "hard parts" WRT to survival have been done on earth [for a poor ROI on earth!], and the really hard parts WRT time differentials and manufacturing look very much like self driving cars and robots made for the moon or mars. Teslas and Foxconn, friend. Europa is just... what we do every day in Subsea exploration + what we do every day with our _amazing_ rover program.

I'm not saying we're there tomorrow. I'm saying that if our robots are there next week making oxygen generators and water pumps and harvesting and collecting, with steady resupplies of better robots and smarter factories, we could Kerbal ourselves f-ing far. H2O is rocket fuel - pure delta-v. Independent mining robots could extract the raw ore for our Expanse/BSG-ish space fleets over the next hundred years, and your grandkids could figure out how to spend an asteroids belt worth of mineral fortune :)

There are many Billions being spent on this pursuit today, in 2018. Cynicism aside, sometimes the VCs know a thing or two...

You can't for AT&T U-Verse. They won't assign an IP address to a 3rd party device. I've been meaning to get some cards and do some raw frame dumps to try to figure out how their Fiber modems work and see if I could get it to assign my own device an IP address. It's on the long list of things to do.
Maybe so, but from a submission quality perspective we all gain by waiting till these things actually happen. Most don't.
> But why is it only women are expected to provide such care and are classified as gold digging whores if they think the father should provide for them while they do so and also provide some compensation into the future for the lost career building opportunities it costs them? Parents should both be responsible for the product of having gotten jiggy together, not just mothers.

How does that contribute to women being in poverty at a higher rate than men? If the parents are married, they share finances so they are either both in poverty, or neither are in poverty. If they are divorced, the primary caregiver will be compensated for their time through child support payments.

And I don't think stay at home mothers are generally classified as "gold digging whores", maybe my experience is different from yours though.
In the USA, alimony and child support serve this purpose. Other developed countries are similar, or have strong non-gendered social security.

In USA, while women are in poverty more than men, likely for the reasons you highlight, women receive more social services than men, for those same reasons. Homelessness disproportionately impacts men (by far), because woman and children have more access to social services.

What’s wrong with more than one “green” solution in transportation?
Your comment expresses a really common sentiment, but it also vague and offers no supporting evidence.

When was a model like React + Redux (or Elm) used previously, and why did it fail? The combination of factors (browser advances and iteration on existing models) is unlike anything before. This tech stack did not exist in 1999, it did not exist in 2005, and it did not exist in 2012. It is driven by real problems.
True. But the reason for this is because if you lose 90 percent of your men to war, you can enact polygyny and rapidly repopulate. But no matter how many men a woman sleeps with, it takes 9 months to complete a pregnancy. Whereas a man can father children on multiple women at the same time.

Not does that alone justify keeping them in poverty.
Definitely agree that there are degrees of freedom, I'm just not confident that a removal of regulations in the healthcare market would lead to a positive outcome (higher quality/less expensive healthcare).

>> Services are requested under the duress of health problems without the ability to end the agreement.

>That is the nature of any insurance market.

I was actually thinking about when medical treatment is being received. Once you're under a hospitals care you're largely subject to their pricing for services (e.g. I can't choose to use the cheaper MRI machine down the street). There's a bundling of services at a healthcare provider that seems to contradict free market arguments as well, but I was mainly trying to get at the (effectively) binding agreement to use a particular facility once you are checked into it.

Edit: To be a little more concise, you agree to a particular payment structure for services without knowing what the cost of the services are or which services you'll be receiving when checking into a hospital, this opacity in hospital pricing also means that different parties are paying different rates for the same service at the discretion of the billing department.
> 73% of the labor cost

Key qualifier: "of the labor cost". Presumably, there are additional, non-labor costs that may not be reduced by more efficient communication.
>A policy decision by whom?

By your government?

> Specifically, how do you do this when IP spaces are controlled by various unfriendly countries around the world

You begin a "911-certified program" that requires your local ISPs to register their IP ranges with some central authority. The rest is a bunch of detailed but solvable details.

Your idealism when it comes to making this seem more complicatated that it really is seems misplaced.
Is this issue only of concern for Intel with Linux? What about OSX, BSD or Windows?

I think there is a difference between unsubstantiated vilification of an amorphous or undefined group, (headbangers, techbros) and particular individuals (i.e. doxxing). I mean, sure you had an exception where Ozzy "ate a live bat" but it was more about "more at 11".
I run lastpass, I only use a unique password for that application. I also rotate that password every few months.

I also have it set to 2FA with google authenticate, so I need to have my phone everytime I log in. It takes longer to login but its worth it

So even if my password were compromised by a keylogger / brute force, you would still need to have access to my phone.

I don't use lastpass on my phone so that's not a nonissue for me. I don't link my phone to my computer at all (airdroid, teamviewer, etc). You would need to have

- My master lastpass password

- My unique phone password and my phone

Both events are kind of unlikely to happen. I worry more about lastpass leaking passwords than me being hacked at any point, since this is the major disadvantage of using lastpass over keepass.

lastpass is nice since I can just make autogenerated throwaway passwords and have a way to take notes on passwords I change over time
From what I understand of real time traffic data, most of it is generated from mobile users themselves. That means for the most part it'll be Google, and to a lesser extent Apple.

If Google thinks it's in its advantage to keep that data closed to benefit their business model, then no one else has access to it.
You still haven't actually laid out a metric showing that Medicare is inefficient; you just keep asserting it is not efficient in the face of evidence that single-payer systems are in fact pretty efficient. To add more evidence to the "you are incorrect and single-payer systems are in fact pretty efficient" pile, here's another potential efficiency metric we could compare: Medicare spends significantly less (approximate 1.4%) on overhead costs, compared to private insurers that average around 12.4%.[1]

So, again: the US as a whole, using a primarily market-based healthcare system, spends more money per capita for worse results than most other developed nations, most of which are using single-payer systems. Within the American healthcare system, there is a limited single-payer system that only covers a particularly high-risk patient population, and yet despite that patient population, runs more efficiently as an organization than the market alternatives. What evidence are you offering to make the argument that that limited single-payer system is actually more inefficient than the private alternatives?

I feel that BTC in future will be studied as the mania that separated lots of fools from their money.

I do, however, feel it is a good hedge.
I'm the exact opposite. I often work at a standing desk and I can last a lot longer standing in sneakers than leather shoes.

The big reason though is that I'd much rather have 4 pairs of $100 sneakers than one pair of $400 leather shoes. I get bored of wearing the same shoes and being able to frequently swap them out for new ones is part of the appeal.

Humble Bundle Python Deal
Given what's been disclosed so far it seems an exploit using rowhammer techniques would be unlikely to work with ECC RAM. Consumer systems will be screwed unless a tolerable microcode update is released.
When you're building out your DC, its a function of cost relative to performance/power use. I could see new setups may look at AMD over Intel, especially if they're running workloads impacted by the software fix, at least for the current generation of CPU's, maybe even the next 1-2 that are in the pipeline.

When you're scaling up/maintaining your DC, you're much more likely to be looking for single sku, like for like products that allow similar tooling, knowledge base, experience etc... Like you said, monoculture has its benefits in some situations.

Personally even with this bug I'd be very hesitant to switch. Our previous tests between them for very specific workloads showed our best cost/performance was with Intel over successive generations, and the scaling/tip over points were different. We have a combination of experience and knowledge around the existing arch and how our applications and workloads interact with it that involved a number of pain points that I'm not sure its worth it to re-experience with another arch.

On the other hand, those running on non-bare metal, cloud based, auto-scaling/automated solutions that have a wider tolerance for individual app performance, are probably in a situation where they care less about this, but at the same time have little to no say in the arch they run on, that decision is left to the cloud providers they use.

just my 2 cents anyways.

These are not just surface voxels, but occlusions will limit angle info. In the paper, it's explained how it is possible to extract 100 Million voxels of information out of 1 Million pixels measured - by using compressed sensing and assuming that the object has some structure (is not totally random 3D distribution). This compressed sensing trick is not new but is a large part of what distinguishes this work from light field cameras, which cannot extract so much information and so must trade resolution for depth info.

This is similar to why we are doing it ... our app is quite simple, with about 5 moving parts. But we need it to be able to keep running continuously while allowing each part to be upgraded independently, and to be able to shut off the valve of messages going to each part so we can upgrade it and test it without bringing other parts down. Several of the parts share data models and underlying code ... so perhaps they are not true "microservices" ... but to the extent they are, for us there are some useful aspects to the fad.
The obvious answer is that web-based apps are effectively access restricted so the developer can charge any price they want including free, change prices at will, and enforce it effectively over the long term.

Native apps struggle with this.

Things that are easy to monetize tend to attract more effort than things that are possibly impossible to monetize, or have very limited monetization options.
Go to https://www.coinmarketcap.com, visit some of the websites of the listed altcoins, and each of them will (hopefully) make a case on why their coin is different, and what problem it solves. Many of these altcoins are made by scammers who want to make a quick buck from a pump and dump.

For a notable example of an altcoin that solves a tangible problem, consider Monero. This coin uses a sophisticated transaction system to hide the identifiers of participants in a transaction. I don't know whether it is bulletproof, but it does claim to be much safer in terms of privacy.

Another one is Verge, which routes all of its transactions through Tor. I'm more bearish on this one, and its recent spike in market-cap was short-lived, suggesting that the idea still needs work.
Just about every web-based Java project I've came across carries a certain persona of UX being terrible to navigate, slow to use and all around a negative experience once you try something that just works.

I recall there was one gimmick where a camera processes the position of the pupils of an observer and changes a display based on the position of the pupils relative to the display.

It is not strictly stereoscopic, but there's an uncanny 3D effect where foreground and background move relative to each other when the observer shifts position. Sort of like paper-cutouts.
Though if it were going to be fixed in microcode, it seems like this would have played out by Intel just having released new microcode already and encouraged people to update to it, rather than every OS vendor scrambling to rewrite large chunks of their memory management, you know?

you could try but the amount of angle information in the data will be so small that noise will destroy the results. Said another way, the diffuser makes the forward model more invertible (better condition number).
