Why would Russia, China, or CIA test it on American diplomats though? They all have access to plenty of people on whom they could test this, in a way that no one would have ever heard about it. Supposing it is some kind of weapon, by testing on American diplomats they just revealed its existence.

If the transaction hasn't been committed (etched into the blockchain), then isn't there a financial advantage to accepting the highest fee transaction?

The protocol doesn't matter, mempools aren't validated or shared[+], and so the validity of the chain isn't challenged by processing the higher fee.

So given that the bitcoin network is designed to be operated by greedy miners, surely one would break with "tradition" and process the second?

You might have to dig to find a route to those nodes but it should surely be possible.

[+] They're not shared as in shared-state, i.e. sync'ed.
This is my sentiment as well. I have BS in math and MS in applied math and now work as a data analyst. Problem solving and abstracting problems to general properties and attributes are the most worthwhile skills that my math education has provided me, at least as marketable skills. I learned R and python on my own and no doubt this has been a huge help in finding jobs, and has allowed me to be closer to the tech at my jobs versus a more traditional excel based biz analyst role. This has allowed me to learn a lot more on the job, like being able to directly touch dbs, create my own ETLs, learn AWS products, etc.

You (OP) may take for granted the way that your math education shaped your brain to think about things. Don't. This mode of thinking is one of your biggest assets that employers are after.
Would be nice to have some indication of pricing before I jump in.
Good example with IRIX. I liked it as well, but I liked HP-UX too. So, YMMV.
Well said. I’ve come to distrust FB and Google so much I am very unlikely to buy their products or leverage their services.
That hasn't been a motto at facebook for years. It's now "Go fast with rock solid infra".

Move fast and break things is a motto for startups that might not be here 6 months from now. Speed is important because surviving as a business is the most important priority.
> Did you mean "physical replication"? Logical replication corresponds to MySQL's model

nope postgresql supports logical replication since 10. https://www.postgresql.org/docs/10/static/logical-replicatio...

> Whether an "easy" multi-master galera set up is actually production-quality is another matter entirely, but it is not difficult to get up and running.

if you have regular network partitons (actually having network paritions is always the case, especially inside clouds) than a galera cluster can actually broke in several cases that are even worse than any failure even the most broken replication on postgresql/mysql non galera can do.
Yeah that's more correct.

Technically the miner needs to know what they are going to be including in a block when they begin trying to find a valid hash, but for the sake of explanation I generally switch it around for simplicity.

Exposure to pesticides via "pesticide drift".
I did a double major, math and physics. I was basically self-taught with respect to computers (one CS class on my transcript). I got hired as a programmer by a lady with a Master's in math, who was largely self-taught with respect to computers. That first hire is all it takes - after that, I had experience.

I graduated in 1984, though, so this may not be very applicable to the current situation...
after long periods of sitting, you end up having to confront pain very closely. When you inspect it with your meditating mind, you can actually see that it isn't directly "hurting you". Instead the pain is just recognized for what it is, a physical sensation; energy moving through your body that is ever slightly changing and won't last.
Both sides of this particular debate seem to be stuck in this silly false dichotomy where you either have insecure electronic voting, or entirely revert to traditional paper ballots.

We can have sophisticated and safe electronic voting, but we have to introduce it gradually, with transparency and major, sustained investment.

We must also do something that doesn't come naturally: Critically review and audit progress to-date, and use this information to conservatively set direction for future effort. The aviation industry's approach to technology is the kind of model that is needed here, not that of startups or big corporate.
Yeah, middle class isn't as much of a target since they push back more than the poor. I read a great quote from John Rogers on twitter that put it in perspective for me:

"you're life's not good because you worked hard. Plenty of good people work hard & their life is still shit. Your life's good because you haven't been judged a sufficiently delicious morsel by someone higher on the economic food chain."
I have family that own and operate farms in Kansas and Iowa, and that's pretty much on point. Good quality farmland pretty easily goes at $6k an acre, with really high quality riverland going for up to $10k.

Or just install XP in a VM, then VB6 will work for sure.
I love nerding out over this personally, but if you're a startup, given the plethora of well managed offerings, you're frankly foolish to invest resources on this. Even if you eventually reach the point where it makes financial sense to hire a full time ops person or DBA, the opportunity cost of having a smart engineer (and it does take a smart engineer to manage a multi-master database) work on infrastructure instead of your actual product, is just stupid.

How many startups have failed because they spent too much money building "cool, nerdy, infrastructure" instead of just building a product?

That seems like confirmation bias. But yeah, good idea about compiler integrity.
Okay never mind don't read my sources. This 3D printed Plastic is using backscatter techniques. I'll just quote the article and realize your not understanding where this invention is coming from and why this is new worthy and not just some wifi reflections.

"To 3-D print objects that can communicate with commercial WiFi receivers, the team employed backscatter techniques that allow devices to exchange information. In this case, the team replaced some functions normally performed by electrical components with mechanical motion activated by springs, gears, switches and other parts that can be 3-D printed — borrowing from principles that allow battery-free watches to keep time."

...

"Information — in the form of 1s and 0s — is encoded by the presence or absence of the tooth on a gear. Energy from a coiled spring drives the gear system, and the width and pattern of gear teeth control how long the backscatter switch makes contact with the antenna, creating patterns of reflected signals that can be decoded by a WiFi receiver."
The explanation for bitwise complement ignores the word-size which matters a lot here. For example ~4 = 251 in uint8, not 3 like in the example.

Nobody really has "control" of their SSN anymore; most have been leaked one way or another. The only effective control is locking your credit files.

Even if you generate a new private key for every loan it wouldn't help much. A significant fraction of borrowers will still lose control of their keys during the life of the loan. So the reality is that to make such a scheme workable would require one or more trusted central authorities to perform identity management and key recovery. Who would do that work and what's the funding model?
I don't see the causation in your argument. Can you elaborate? It looks like you are only implying that there is an impact, but I fail to see how.

VMWare Hatchway: persistent storage for cloud native applications
The suggestions mentioned in this testimony basically recommend doing just that. Paper ballots are used to keep a record of the vote in the case of a system outage or if a manual audit is triggered, but for the most part you would never do it that way. Statistical analysis is used to trigger alerts that there may be fraud happening at a particular polling station.
Go to Settings, focus the search text box at the top of the screen. Enter “driving”, it should show “DND while driving”. Turn that on. Not much of a deterrent, because there's a "I'm not driving button" when you try and use your phone. That's understandable, since I doubt "Fuck everybody else, I've got toots to post!" would fit in the modal, and localization would be difficult.

I also thought it was the default, but obviously not.
> What value?

The authors point is that publishing examples that fit our expectations of a standard example (employer & employee) is also a political statement, just that it is one in support of the status quo and therefore provokes little response. But it is still a political act, which contributes to the pervasive sense that the relationships embedded in the examples are natural rather than arbitrary and challengeable.

Its not a bad thing. But it is quite annoying that the places who benefit the most from taxes keep trying to abolish them out of a lack of understanding, and also get an oversized influence in terms of voting value to do so.
You can't know. For those who are saying it is obviously a bubble: If bitcoin "succeeds" and becomes widely used as money, then its value will grow a lot more, since there can only ever be 21 million bitcoins. It is inherently deflationary. One bitcoin is worth, roughly (and circularly) speaking, the total valuation of bitcoin divided by the number of coins. Another way of looking at it: imagine bitcoins become as widespread, and as desired, as USD. Now think about how many USD are in circulation compared to BTC.

I know it is not really that simple, and dollars have some special properties compared to bitcoin: you have to pay your US taxes in USD, for example. Also, it is easy to talk about "valuation" (in e.g. USD, EUR) if you view bitcoin as a commodity - but if it becomes a dominant currency it is not so simple. You can still reason about exchange rates, and my point is, the asymptotic exchange rate USD:BTC (assuming no dollar inflation) is not of the order of 10000:1, but much higher, maybe 1000000:1.

Yeah. If someone claims data, reproduce their experiment. If someone makes a point, check their math. If it's beyond the realm of repoducing experiments and checking math it's beyond the realm of human knowledge. Sorry, but time and time again our kind have proven to be liars; and worse, self-decievers. Nothing else is left in ourselves to trust.
What is the difference between mech and industrial?
We tried a couple of weeks back, but then most dependencies have not been upgraded yet. The problem is that, to my knowledge, there is no riak_core for Erlang 20.
That's interesting, my PhD is in an engineering field and projects have included a lot of what you mentioned ('graph theory, markov chains, ... cluster analysis and signal processing'...). I just went through a job search and couldn't find anyone very interested in these skills, so I'm back in another postdoc. Any advice on companies/industries specific to those types of methods?
Hope this helps.
Trade (YC W17) is hiring – Build the future of trade in Africa
Trade is building a platform that we hope will someday power the trade of everything over distance in Africa. Right now we trade maize in Ghana. Since launching last October, we’ve traded over $1.5M worth of goods.

Our opportunity is that traders in Ghana take 40 - 70% of the final price of most agricultural goods. We handle the logistics of assuring quality and exchanging goods and payment, so that both buyers and sellers can get better prices.

We are backed by the Bill & Melinda Gates Foundation, Y Combinator, Sam Altman, Peter Thiel, Founder’s Fund, and Reid Hoffman. We are extremely ambitious and are looking to hire more people to join our team. If using Angel List to apply is annoying, feel free to email wilson [at] tradeghana.co

Positions (all are full-time in Tamale, Ghana):

UI/UX Designer: https://angel.co/trade-4/jobs/306791-lead-designer

You have strong opinions about good design process when building a product and want to spend a lot of time talking to customers. You’re very organized and responsive, and enjoy having lots of product decisions depend on you.

Backend Engineer: https://angel.co/trade-4/jobs/274673-lead-backend-engineer

You have a strong sense of system design and tradeoffs. You’re excited to build the service layer to move trucks, goods, and money with an API call.

Product Engineer:
What we mean by this title is a mix between a product manager and software developer. You should be an extremely competent software engineer who wants to have more product ownership. You want to talk to users, own timelines, and maybe even do some design.

We want to hire product engineers with several different focuses

Payments and Financial Services: https://angel.co/trade-4/jobs/306781-product-engineer-payment-and-financial-services

Transport: https://angel.co/trade-4/jobs/306778-product-engineer-transport

Someone must have mentioned this idea somewhere:

Use something like a cryptocoin. You go to a voting office, get approved as a legit voter, and they send you a coin. You send it to some address for a candidate. Everyone can see the result.

Pros/cons?
OK, but voting is also a very short part of the democratic process. Voting needs to be reasonably fast so that the decisions are then enacted. If recounts cause the process to take months (which I believe was the case back in 2000), then it also makes the transition process take longer and seeds ever more doubt into the process. Just look at what happened in Kenya recently.
I read your sources. Nothing you quote here contradicts what I said if you read it in the context of the entire paper. E.g. " creating patterns of reflected signals that can be decoded by a WiFi receiver." isn't technically wrong, but very misleading, since what they analyse for data is the signal strength the receiver sees across the packets, not the content of the packets. That's why we are arguing that they present it terribly.

A Wifi packet is a few milliseconds long at best, it should be obvious why a 3D printed mechanical thing can not be fast enough to change bits in there to actually generate a new packet.

Please note that I'm not claiming that it's not using backscatter techniques, that it isn't novel or that it isn't interesting. Backscatter is a generic enough term to cover all these things, despite them being quite different.

I'm claiming that it does not generate Wifi packets. It merely changes their physical characteristics in a way that can be detected, without changing anything about the packet contents.
You are correct. LLCs don't pay federal business income taxes. An LLC can retain earnings inside of the company but the members are still going to be taxed individually as if the earnings had been paid out to them.

Unfortunately this is a losing battle because no matter what is said a laymen will latch on to any uncertainty presented to them regarding scientific discussion(s), be that evolution or climate change.

They don't understand that scientist by nature prefer to never say something is 100% one way or another. This is because we all know over a long enough timeline just about every conceivable outcome will occur and so scientists, rightly, try to be accurate when they talk about this stuff.

Politics isn't about presenting honest clear facts but rather wordplay meant to serve their donors.
a) they should be using segwit addresses

b) they have the option of using a payment processor that handles ALL OF THE PROBLEMS THEY DESCRIBED on the backend, behind the scenes

c) switch to a different blockchain. they already built the rails, different trains can run on them already.

d) bitcoin futures start trading on Sunday, its an easy way to hedge volatility, so there goes that argument. Professionals in multinational companies know what these are used for.
We've mostly had this for years, in the form of PayPal. Your ID even is your email.

The issues with PayPal have mostly been interfacing with fiat currency, which any system will have to deal with, and transaction fees, which any system will have.

The real problem IMO is the lack of a de-facto service that everyone all around the world has, and we're kind of in this position: https://xkcd.com/927/
Every major blockchain is working on scalability (sharding, offchain transactions, and various other solutions are in the works)

So ideally there will be more traffic but less congestion
One piece of advice I would give you is to think about where your particular area of focus in math overlaps with CS, how you could apply that towards a real world problem / situation and how you could tailor your education towards that goal. People in Math / ML / Stats with the chops to translate their research into production quality code and systems are in huge demand.

It's 2017 the solution to this problem is never answer a call from an unknown caller. Problem solved especially if this guy, his wife and other family members followed this mantra. A mantra Im sure all of us follow on Hacker News.

I only pick up the phone from those in my phone book or have a call scheduled with someone new. I then add them to my contacts or make note of their number.
> For example getting home and having the lights turn on that you'll need automatically.

This would be easier to determine if I lived alone. When someone comes in, someone else could be sleeping, watching something in the dark, etc. There's a decision tree for which lights to turn on and how bright.

What I would expect the lights to do is more complex than I would want to spend the time perfecting. I like tinkering, but not with things that I actually rely on. That's why I haven't tried it. Well, that, and because I'm not willing to give an appliance an internet uplink.
I commented this somewhere below, but it also applies here:

Would this allow you to prove to someone else how you voted in the election? If so, that's not a desired property.

Currently there is no way for you to prove, to yourself or someone else, who you voted for in an election because nobody gets to see your ballot and you cannot take a photo. This makes vote buying and coercion much more difficult. I'd like our voting system to keep this feature.
Tell me how you bootstrap photo ID in your country, and I'll tell you whether I think photo ID means anything.

In our case, we don't care at all what you look like, just that you're the same person we were talking to earlier - and ideally that you're the owner of the method being used to pay, though that's not always true or necessary. So the photo is meaningless to us.

Besides: who is looking at the photo and confirming that it's the same person as the one in front of them? Yep, an human. The whole point of this discussion is stopping the human making human-factor judgement calls.
It’s weird that the article author attributes Susan Fowler’s blog post as the reason for Travis Kalanick’s resignation when it was really more of an incidental symptom of the many underpinning factors that ultimately led to the board’s letter asking the former CEO to step down.

The important impact of Fowler’s post was the investigation that led to dozens of employee removals—the C.E.O. resignation wasn’t the primary effect.
Same here. I had months of calls from the agency and I think only because I was extremely forceful that I would never pay them a penny that they finally backed off and told the medical provider to bill the f'ing insurance. This was all complicated by the fact that I didn't see any bill for > 9 months (while they were billing the wrong insurer).
Answer: No.

No one gets the secret sauce. They pay for your results.
There's shades of grey here - anything you lay in a fixed diameter conduit is competing for bandwidth in the sense that you could pull another wire.

Consider an alternate history, where TV was invented after the internet. ISPs propose to offer TV service (exempt from data caps of course) at the expense of last mile bandwidth, which is otherwise subject to caps. I think that would be recognized as a net neutrality violation.

It feels unreasonable because we know the cost of providing television service scales with the number of subscribers, not the usage per subscriber. Of course, that's also true for internet service outside peak hours - a fixed monthly cap does not match the unit costs of providing internet at all.

I think pragmatic regulation would exempt existing cases like this. We wouldn't permit a new case like it in the future, though.
