As a former blue apron customer I don't think it was ridiculous. I churned when my wife was out of the country. There are still recipes that they sent that I still cook. Now as a business I don't think they will be able to compete with a hybrid solution that amazon/Whole Foods will be able to devise. But I see Juicero as completely different.
Volatility is the important measure here more than price. If a merchant cannot have certainty that the USD value of their hot bitcoin won't fall between the time they accept it and the time they convert it, they'll be loath to make that any substantial portion of revenues.
This reminded of a nice little book by Pierre Bayard called "How to Talk About Books You Haven't Read", which actually dedicates part of itself not to books which the reader hasn't actually read, but to those which he might have forgotten. Unfortunately, I've forgotten much of the rest of the book, so I really can't say much more about it.

Still recommend it, though.
And as such these tiny tiny cuts are a good idea?

It's very dangerous to call defunding of sciences and regulatory oversight to be "wasteful" spending. They are both inexpensive and tend to be valable for decades to come.

Maybe Trump, his team, and the Republican majority in every branch of government could do something positive about entitlement spending? It'd be great to get back to a US where we actually spend non-trivial money on core science.
Thanks for the feedback. We're investigating this.

It does have a name. You're talking about mBTC and bits

yeah who would ever want something that appreciated in value /s
It's 100% bubble.

It could go up to $6,000, $50,000, or even $1M. It's not localized like tulips, and it's connected to the internet, so the universe of people available to fuel the speculation is enormous. That the Chinese are highly speculative is what's mainly driving the current price.

It has no intrinsic value. It's like gold in that it's not a productive asset. It doesn't yield anything like stocks or bonds. The only thing a bitcoin holder can hope for is that someone will buy their coins in the future at a higher price.

The interesting part is watching human nature unfold. People who hold bitcoin mistakenly believing they're investors because the price action is reinforcing that belief. They're 100% speculators by definition. It's OK to speculate. It's neither illegal or immoral, but you should know when you're speculating and when you're investing.

You can't make this stuff up. Look at the people coming out of the woodwork: The Winklevoss Twins, Dan Bilzerian, professional wrestlers, and such. All the community leaders are either fighting with each other or in jail.
DNM is something I had to look up. I don't have to explain why going to the store and being able to purchase something with Bitcoin is not the same as buying drugs on the black market.
I threw away hundreds of Bitcoin on formatting a drive many years ago. never thought they would be worth more than a few cents. I revisited in 2014 and have been accumulating ever since.
26 is also a (well-known) numerical value of YHVH, i.e., Yahweh :)

10 (yōḏ) + 5 (hē) + 6 (wāw) + 5 (hē) = 26
It's almost the reverse... high BTC/USD ratios mean high real transaction fees and long confirmations, even for small purchases. The fork made it better, but I don't think this is a solved problem for BTC.

Litecoin evangelists will point out that the usability of litecoin is currently far and away better. Part of that is certainly attributable to design, but part of it is attributable to LTC/USD being a better ratio than BTC/USD, meaning a 0.001 tx fee is a few pennies in one and a few dollars in the other.

The popularity of a coin increases adoption (and so network effects), but increases hurdles to usability at the same time, it's a really fascinating game theory situation...

We might end up with a suite of coins that users bounce between, or maybe some clever altcoin designer will find a clever fix for some of these issues. Not sure.
Is your company one of the hot ones right now where developers are lining up?

Assuming not, what's the compensation for the job? Have you tried posting the compensation for the job publicly?

The reason I ask is because as someone who works for one of the big 5, I don't even consider companies outside of the big 5 or top startups. As "cynicalkane" said: "Much of the industry is not only unaware of reality but refuses to believe in it. This includes real engineers who do real work at real companies and comment actively on Hacker News. $250k for a senior engineer is just completely outside their reality."

Are you offering 250+ for senior engineers? If so, broadcast it and people will interested. Else, I'll assume you are going to just offer non-market rates and waste my time.
So true. My fantasy company (please anyone start it) is "reverse-Amazon-prime"-- Remove anything from your house in 2 days. Then you have all the connections to a) sell and share the money back with me, b) donate it, or c) dispose of it responsibly. This would be so awesome done right with solid research into the best ways to do all of the above for a huge variety of stuff.

Hi,
cool site.

You might want to consider redirecting requests for your IP address to go to your domain name.

Something like:

server {

listen 443 default_server ssl http2 reuseport;

listen [::]:443 ssl http2 reuseport;

server_name doorbell.io;

# redirect IP address requests to https domain
if ($host = '192.241.177.143') {
return 301 https://doorbell.io$request_uri;
# you might want to use code 307 in place of 301 if you care about POST requests etc
}

I agree. The degree to which that pie chart is both hideous (we can do much better in 2003, oh wait, 2017) and uninformative+dishonest makes me not want to trust IBM with understanding any of my data (which is what machine learning is all about).

Heck, the fact that the humans at IBM can't classify it as dated makes me suspicious of their ability to make a machine classify anything.

IBM has been making a lot of marketing efforts around trying to own 'big data' and machine learning. Depending on who you ask (typically people entrenched in the dying mainframe space), IBM already is the predominant choice in cloud. If they're going to rely on marketing exclusively, they should at least shell out for pretty graphics.

Many people buy gold for “post apocalypse” scenarios. How well is the bitcoin network going to work in the post apocalypse?
Correction:

you can store and send any arbitrary amount of database entries
and wait for several minutes while your transaction is processed
It's not just for illegal activity, it just seems like that's a huge percentage of its current use. Not unlike Tor, sadly.

It may be more fungible at the moment, but is it anywhere near as safe? Gold goes up and down but nowhere near to the degree we've seen with bitcoin. Add a minimum it's useful in manufacturing so even if the price crash there would still be people to buy it. Rolexes are useful, they have an intrinsic value/use. Bitcoin is only valuable as a medium of exchange.

Bitcoin could effectively disappear. I'm not saying it looks likely at the moment but even if your holdings are very large all it takes is the market to decide to stop accepting/exchanging it.

I think that's FAR more likely than gold or Rolexes.
But, inflation.
Come on, you guys aren't outraged? It's outrageous.
Here is the topology file btw: https://github.com/tehcookies/devsalaries/blob/master/data/t....
>I just have a very hard time seeing how it's actually useful

Why is it so hard to see?

Whenever you send money somewhere electronically, a middleman takes a cut. With Bitcoin there is no middleman.

It's that easy.
How about calling it malicious UX? Bad is not a strong enough word. Or maybe hateful, or exploitive.
Are you for real? I feel like we're being trolled by Bitcoin holders who want to keep the value propped up.

Help us optimize trucking and logistics - a $800B industry that still runs on fax machines and phone calls.

We would love more engineers, up and down the stack, and anywhere on the generalist <-> specialist spectrum. We use pretty cutting-edge tech (React, React Native, TypeScript, Node, GraphQL), but we're more interested in engineering chops than any particular tech skills.

I've been here since the beginning (over two years now). The team has grown quickly, but we still have a tight-knit and incredibly smart group of engineers. We have an endless supply of interesting problems including machine learning, service architecture, mobile/desktop/web UX, complicated business modeling, and much more.

Some of our backers include Y Combinator (Continuity Fund), the founders of Amazon and Microsoft, and Greylock Partners. You can read more about us:

Alphabet is the only owner of Google Inc stock. They're retiring it all and converting the Google subsidiary to an LLC. That in no way removes their reporting requirements, because Alphabet is a publicly traded company.
The different hashing algorithms have different power requirements.

Scrypt (LTC) and KECCAK-256 (ETH) are less power intensive than SHA-256 (BTC). Those are just proof-of-work.

Proof-of-stake or proof-of-importance would have barely any power footprint, but there are still debates about whether they could replace PoW and offer similar security guarantees.
Just to clarify for everyone: Be careful switching your career to netsec/pentesting. If that's your thing, great. But you're likely to be a "lifer" because no one will want to hire you anymore for webdev.

It's not quite as clear-cut as that, but if you're out of the game for N years, it's really hard to get back into it. Especially when you're not younger than 30. Ageism is a real thing.
in my previous trips i have never seen a room rate at one of these booking type websites that i wasn't able to get by going directly to the hotel website or by phoning them.

Bitcoin has indeed appreciated more than any other investment in human history. In 7.5 years it went from $0.003 to $4900: a growth 1,600,000×. Imagine investing ten bucks and a few years later it is worth $16 million!

For comparison: the founders seed round of Uber grew their investment 65,000×, tulip prices increased by at most 5,000× during tulip mania, some "best performing stocks" over the last century are reported as growing 1,000×.
the holding "Company" of the "holding companies" likes cryptograms and these are actually pretty good. "clash" implies "two" parties but if there is only one then it is consistent.

"XXVI" for "2" => "13" + "13".

naming is hard and these are fine names. they need no "introduction".
I was eating dinner with two doctors about a month ago, and they were discussing this. They said it was difficult to prove that coal mining causes things like lung cancer in the miners themselves because it is just about impossible to find a coal miner who doesn't smoke.

Why other mathematicians at the time, were so nasty towards Cantor's ideas?
The quotes noted in the PDF -- just sound nasty and dismissive (or may be this is not the whole story)
Not involved in the company, but fyi the reason for that is because this is the pentest equivalent of not having any github repo as a dev. There's virtually no barrier to playing/attempting a ctf or testing a vulnerable VM, so it's sensible to expect that of all candidates and shows a genuine interest.
Why get outraged, when you can just stick your head in the sand?

To what extent do you think the value of bitcoin is driven by its use as a black market exchange / laundering tool?

I suspect virtually all of it. People dismiss this viewpoint because they attribute it to Silk Road type activities, which can't explain the scale, but what I'm talking about is millionaires and billionaires funneling wealth out of China etc.

One thing that's certain is that bitcoin isn't really a currency. When you pay with bitcoin, the value is tied to and converted to USD, and the price paid is tied to USD. Bitcoin isn't the currency in those transactions, USD is. Bitcoin is more like a decentralized anonymous Western Union than it is a currency.

I also don't understand what proponents think the endgame is for bitcoin as an investment-grade asset. Everyone who buys some just becomes the world's first trillionaires, and we become a 2-tiered society of people who bought bitcoin and people who didn't?

Bitcoin might have some serious world-changing implications, but I seriously doubt it being an investable asset is one of them.
Minimum viable product (MVP) https://en.wikipedia.org/wiki/Minimum_viable_product
It can't go up forever because the knowledge of that trend would make more and more people invest in them.

At some point this would cause people to build stashes of tokens instead of investing in real businesses with real production capacity.

When this trend would become widespread enough, it would eventually cause global production capacity to drop. That's right, when enough people do it, token hoarding displaces investment in businesses and factories and lowers global production capacity. This means token hoarding causes a future drop in things available to buy with these very tokens.

Eventually there will be people who want to buy real things with their stock of tokens. The tokens will be chasing fewer goods which would mean prices for stuff would rise (tokens would lose value). This could happen suddenly when people with large stockpiles of tokens notice that value is dropping and that there are tons of other tokens waiting on the sideline ready to make it drop even further.

Hoarders might rush to get rid of their stockpile all at the same time before they're worthless which would cause their fall to worthlessness. This drop would bring the tokens closer to their natural intrinsic value of zero. The cycle can then start again, such is aggregate economics.

The 1920s and 1930s suffered from this type of production drop but with gold tied currencies instead of cryptocoins. It happened to a lesser extent in 2007 when western world central banks failed to keep inflation rates high enough.

It's important for the world's sake to not let deflationary currencies become too popular.
When savings or financial promises are insufficiently tied to future production or to accumulation of real goods, there will be disappointment when many people try to exchange them for real stuff. That is true for crypto currencies as well as government currencies (that is why the system is designed to make banks invest people's money in real businesses and minimize the proportion of money that is stockpiled idly).

It's true that crypto currencies are currently not widely held enough to significantly affect the aggregate economy but speculation already keeps them volatile and the knowledge that as they get more popular, there will be more macroeconomic pressures towards volatility keeps the speculation wild and cryptocoins unstable.

Currencies that are not designed to lose value over time can not be stable. Intrinsically worthless tokens engineered to have better than market risk adjusted, liquidity adjusted, real returns compared to real productive investment will always fluctuate increasingly wildly as they get more popular.
My "Surely this is one of the first applications that popped into your mind." and mentioning "demographics" was a priming attempt partly prompted by the authors' affiliations.

Another question is: how pertinent could this be and could it serve as evidence. Is it as "receivable in court" as fingerprints? If it can be "evidence", how to deal with tampering and entities trying to frame each other by mimicking each other's fingerprint to 'cover their tracks'? Could there be a "market" for fingerprints where you just download a set of fingerprints, write [and compile] your code, and then "apply" the prints to the code? Would there be tools to detect genuine, organic, fingerprints from synthetic or after the fact prints? Can you detect how "fresh" these prints are? Can there be a "glove" equivalent so your fingerprints don't show? Can there be a tool to remove your fingerprints after the fact? Can you apply multiple prints successively? This is indeed fascinating.
No, there are some that don't use proof of work, so no burnt energy. Bitcoin is the king right now and Ether the queen, and those two do burn energy.
What I find, is that I will read something, and then "forget" it fairly quickly, but then I'll be doing something else, maybe getting stuck on a problem, and suddenly find that during my thinking or puzzling I will have a memory from that thing I read, and that will help me move forward.
Should have been something like Hooli
Alternative crypto currency network designs try to reduce the energy cost of PoW though delegation to a limited set of masternodes, or via "Proof of Stake" which so far has required a pre-existing supply of coins to exist (and one should ask who mints the supply...?)

It's actually less useful. You already have banks doing the exact same thing for free, while insuring your money, you don't get hit 3% for transferring it into the bank, and there's interest accrued, not wildly shifting value where you might lose half in a few hours.
It exists and is called Craigslist.
WeChat is deeply integrated, the UI is excellent, it's fast and responsive even on low-end handsets. It's a 40MB APK that could well be the only app you need. WeChat is incredibly feature-dense, but it's also slick, efficient and highly usable. I don't like the monolithic app model, but WeChat have implemented it extraordinarily well.

Tencent are a phenomenal company that deserve far more respect in the west. The Chinese market may be distinctive, but WeChat's dominance of the Chinese market has come through innovation, clever design and good engineering.

Elevate Security | Lead Front End Engineer | Oakland, CA | ONSITE | www.elevatesecurity.com

Data breaches increase every year as attackers continue to target employees for access and information. Elevate Security is creating a world where employees are a company’s strongest asset in defending against hackers. We are taking on this longstanding gap in the security space with a focus on behavioral and data science to improve security behaviors across employees in a measurable way. We’re looking for extraordinary and passionate people to help us build this future and redefine the security landscape.

We're looking for a Lead Front End Engineer with very strong JS, CSS and React experience. You think of yourself as an engineer first, but have an eye for good design. If you've got full stack experience, all the better!

Please, no recent university or bootcamp grads. Also, we are unable to support remote candidates or those outside the US needing visa sponsorship.

For more information, check out our job description and ping us on https://www.elevatesecurity.com/jobs/.
If you're reading books for the details, you're doing it wrong.

Read books for ideas. You can always look at the book for reference when you forget the details.

I despair for the people who are taught that learning is about memorizing facts. Ideas are far more powerful than facts and a heck of a lot harder to lookup.
I think it is an interesting technology but I don't think it is as revolutionary as many people think it is.

Bitcoin-like blockchains do not scale like conventional "distributed systems" are expected to. The Bitcoin network handles 7 transactions a second if there are two nodes or if there are two billion. You get more durability and possibly more trust if there are a large number of diverse nodes, but you don't get more capacity.

The scenario where a few traders who meet around a buttonwood tree (see https://en.wikipedia.org/wiki/Buttonwood_Agreement) share a permissioned blockchain makes more sense. The world might need 10 copies of a ledger, but does not need millions.

I think also people have unrealistic political ideas around blockchains. When I hear "fiat currency" I tune out; bitcoin is not the new gold. People wanted gold 4000 years ago, they will want gold 4000 years in the future, in all fictional worlds except for one (https://en.wikipedia.org/wiki/Element_79_(anthology)) people want gold. People won't want Bitcoins 4000 years from now.

Also people have unrealistic expectations about privacy. Sure, governments cannot control admission to the blockchain, forcing you to give over a taxpayer id, but your whole transaction record is visible to everyone. Thus your local government can see you ate at Subway and put the pinch on them and everyone you transacted with. So can the mafia, some other government, newspaper reporters, extortionists, Scientologists, etc.

Ethereum is kinda cool because people can bake applications into it, but there is no real security story for the applications written on it. We see hacks again and again and will continue to see hacks. The escrow model is good for implementing a sports book or equity exchange, but you could not implement loans, swaps, options, etc. on it.

This sounds basically like the 'high responsibility' culture at Netflix. Unfortunately, I don't actually trust that Elon has good intuitions when it comes to management and this particular email is abstract without enough support such that I think he might have woken up another day and written the exact opposite just as convincingly.
I don't think I agree with this, at all. It depends on what you do in security.

If you work as a pentester or network security staff, then you might be trading a career in software development for a career in operations. In that career, it's more likely that you will be challenged _use_ tools, build processes, or fight political battles for consensus, rather than build software.

On the other hand, there are many firms that hire primarily for security engineering and focus on building software. Any skills you have in software development will stay current, and your work in security would make you a better, and more desirable, software engineer.

Anecdotally, I can name many people who have made the jump from security engineering to positions like VP of Engineering, CTO, or simply software engineering.
