Proof of Work demands cheap verification, but Hashcash with scrypt requires as much memory and time for verification as a single solution attempt.

So while scrypt itself is not broken, its feasibility in a proof of work system with a serious memory footprint (e.g. exceeding a single DRAM chip) is.
Huh I stand corrected. I've seen ATF agents[1], FBI agents [2], as well as US district attorneys[3] incorrectly refer to semi-automatic AR-15s as "assault rifles" (which in actual fact are subclasses of machineguns), but since they charged him with that I assume it really must be a machinegun then.

But now I'm really curious to know more specific details about this firearm. Particularly if it was a legally transferable machinegun (legal federally, obviously not in California), or if it was an illegally modified semi-automatic (probably most likely) or a black market gun.

Other people have made the argument as to why we should lower or eliminate corporate income tax much better than I ever could; here is one such argument https://www.theatlantic.com/business/archive/2010/10/why-we-...

In short, corporations never 'take' income. It is the shareholders and executives who 'take' the income. Tax the money at that point, and at a level that offsets the loss of corporate income taxes. This would not be shifting the burden to other citizens, it is just realizing the truth that a corporation isn't a REAL person, it is a group of people, and those are the people who should be taxed.
Well, per the plaintiff(s):

>The lawsuit, filed in the U.S. District Court for the Northern District of California, alleges Uber broadly invaded the privacy of the Lyft drivers, specifically violated the California Invasion of Privacy Act and Federal Wiretap Act and engaged in unfair competition.

It's up to a jury to decide whether or not that's the case here.
No worries. The whole thing was a tire-fire from the get-go, and I certainly don't blame you.
I have always held the view that for intro to programming classes, C was the best language. It really gave insight into what does it mean to "run".

I believe the parent was describing the unsubstantiated belief that press-type juicers are somehow superior to the centrifugal-type juicers you can buy for tens of dollars at big box stores.

I agree with you about fresh squeezed OJ, but I don't believe for a second that it matters if the orange is squeezed in a press or twisted in a rotary. (different kind of juicer, but you get the point).
Seems like a very obvious CFAA violation. "Unauthorized" in that context means whatever the API provider and a gullible prosecutor want it to mean.
The two strangest parts of this are probably the door locking mechanism and the DC motor supply. The door locking was pretty well explained, but I was really surprised at the DC motor. From previous pictures I had assumed it was a 170VDC motor (using just a rectifier + filters for noise) but according to this it's actually a 330V active power correction boost converter. I guess that gets you 100-240V range support, but it seems horribly expensive for driving a motor. Even 170VDC permanent magnet motors are pretty uncommon - they fill an awkward middle ground where the motor is too big to reasonably use a low voltage DC one (due to power supply costs), but too small to use a universal AC motor directly off line power. The only tools AvE has reviewed of this design are the Kitchenaid mixer and Drill Doctor, for reference.

Also, I don't believe "330V 15A" for a second. Maybe 2A...

Not really, if I recall correctly Sony's whole Windows network was compromised via trojans in a PDF attachment exploit. Nothing to do with local vs cloud storage. They certainly couldn't have replaced their desktops with Dropbox.

> Are we to think that our teams are better than Slack's when Slack's core competency is secure communication?

Not necessarily - but they are much better able to restrict things to only your employees by applying VPNs and HTTPS+LDAP auth only proxies. Preventing you from being affected by public breaches like these. The value there is well documented - look what happened when the world moved from exposed to behind NAT routers.

Big public breaches happen all the time - you mentioned dropbox, I've gotten several reset emails from dropbox due to compromise, I'm guessing the attackers didn't walk away empty handed in such cases. A quick search reveals that just last year 68 million dropbox accounts were compromised.

On the other hand, when was the last time an even moderately well maintained SMB file server behind a LAN was compromised directly? Unique zero-day attacks are much more likely to be used on public services too due to the nature of their value.

None of the injuries sustained in the accident were due to the doors not opening. So unless you're arguing that it's ok to sue Tesla merely because they had an accident (even though Tesla certainly wasn't at fault for the accident), I don't know what point you're trying to make.

If you read this article (https://techcrunch.com/2017/04/12/hell-o-uber/) you'll find it goes much futher then just accessing Lyft's public API. They created fake customer accounts, spoofed their locations and even linked the data about drivers they got from this to their own drivers. So what's wrong with this? To quote the article, possibly: "breach of contract, unfair business practices, stealing trade secrets and violating the Computer Fraud and Abuse Act".

Of course it is good for you. Vegetable more so (I would imagine) but fruit juice as well. Would it be better to eat the fruit and veg, sure. But is having juice better than nothing. Yes. Is it better than some other liquid refreshments. Yes.

Is it as good for you as some would have you believe, no. Do some over market it as a cure all. Sure. That doesn't mean, it is bad for you*

* to an extent
amount and fruit depending.
Somewhere in the bowels of Amazon's intranet I came across some HR training games and tried to find out who made them, and with what. It seems like an odd genre. I wound up on a mailing list but still haven't found anything out.

I think there's a big gap between the target market for this device and the average consumer.

A commercial cold press countertop juicer is usually a few thousand dollars. A consumer model is ~$3-400. Cold press juicers are supposed to retain nutrients a bit more, and produce more flavorful juice. (who knows if that is true)

The Juicero is the pro-sumer k-cup version of a juicer. It's not aimed at people who are price conscious at all. Price conscious people could get something close-enough for sub $30. My guess is that the $700 juicer was designed to get a high-end reputation, with lower-end follow on products once they established the brand.

At this point, they are ruined. It's collective common sense that this is a bad deal and the value of the brand is diminished dramatically.

Their engineering decisions are questionable. If you are going for a high-end high quality unique product that will push people to spend double what the competitive product provides, it should be more appealing to look at. It's like they tried as hard as they could to make a cube-shaped plastic lined product as expensive as possible to manufacture. I'm all for sturdy commercial quality components, but not in something that looks like it was manufactured by nintendo.

The Bloomberg article was in poor form. At least let a company get out of the gate and establish itself before tearing them apart. But that's the danger involved with investing big money in companies based on a business plan and not vetting that they are good decision makers. This all could have been avoided if their PR people were on top of things. You'd think they'd have top notch PR people in place for this market segment... another bad decision.
I only had a few days to test for this initial review, so I picked flash SSDs that are comparable in price to the Optane+HDD cached setup rather than the best flash SSD money can buy. The 525GB Crucial MX300 and the 250GB Samsung 960 EVO are both close to but slightly cheaper than the 32GB Optane Memory plus the 1TB hard drive.

Intel knows that Optane caching isn't an attractive high-end solution; they're not trying to pitch it against the 2TB Samsung 960 PRO. They'll be coming out with higher capacity Optane SSDs for primary storage use later this year, though still sacrificing a lot of capacity for the improved performance relative to NAND flash.
If you drive for Uber, you presumably agreed to some kind of contract where it's OK for them to track your every move. Drivers who only work for Lyft made no such agreement with Uber. That's probably what this will hinge on.
Well, that is the biological norm.

Guys, cancer. It's still out there. Donate for research instead of wasting 400 Bucks on a fu*king juice press. No one can justify this useless piece of crap.
Let's see; I'm a successful entrepreneur and I had...

-trust funds - no

-expensive educations - university, but it's subsidized here so it's cheap. Almost anyone who can use a uni education can get one in western nations now.

-the disposable income and lack of financial responsibilities to be able to work for free for extended periods of time - I earned this working at a corp job and saving 30% of my income for about four years

-friends in industry - no

-investor class connections - no

-shitload of luck - hard to say. Probably yes.

You don't need the above; internal qualities beat these externals every time.

Countless trust fund babies have tried to start companies and done nothing but fritter away Daddy's money.

Anyway entrepreneurship isn't really about tech giants. Most entrepreneurs aren't starting giant tech corporations. They're just normal people trying to start a lawn care company, a plumbing outfit, a local chicken restaurant chain, a barber shop, etc etc. These kinds of businesses actually do have strong growth potential if targeted and run well. It's just that very few of their proprietors have the business acumen or desire to do it. I can name several always-packed local businesses in my town that could grow quite easily, but they just... don't.
The article does not say it is a lie. the article says some over exaggerate the benefits. It says the actual fruit is better. But also says juice (reasonable amounts) is good for you.
No, it's not a particularly pythonic thing to do, but it's not uncommon to have a bass class with some methods that should be implemented by children and throw an exception if not. That's not quite an interface as Java has it though.

>No Bitcoin is not a democracy; it’s called a 51% attack for a reason

This quote is quite reductive of all the game theory involved with Bitcoin and I'd argue against Bram on his statement. In fact, Bitcoin is a democratic protocol. Nodes organize around which miners meet their protocol's consensus settings. All that a miner with >50% of the hashrate can do is attempt to reorg a chain of blocks to double spend or DoS the chain by not including certain transaction. A miner with >50% of hashrate cannot force me to accept blocks bigger than my consensus rules state or accept some new ScriptSig with different OP codes.
Yea, violating the TOS of your competitors API so you can directly compete with them is very risky, and due to the overly broad nature of CFAA it could easily end with multiple Uber employees in prison if pursued criminally.

Not that I think it will be pursued criminally, as Uber has power & influence on its side to protect it from repercussions people like myself would face for doing the same exact thing.
> you can't put food stained plastics in the plastic bin (or do you guys do it?)

I believe this is something that varies.
Who do you think is responsible for detecting a breach with that 0day? How about containing (and ensuring your believed containment is effective) and eradicating it? Would you rather have a dedicated security team do this, or would you prefer to have your devs wipe and rebuild naively, hoping they got everything? Even if you go MSSP, do they know your network?

Security is just as much (if not more) responding to a breach effectively and quickly as it is preventing one.
no, it only seems that way because the powerful silicon valley and finance giants are the only ones with access to the top-tier young talent. the rest of the young people out there are inexperienced and not that smart, and definitely aren't worth a six figure salary.

so everyone else just hires older people, but it isn't sexy and marketable to the impressionable technology crowd.
They are, from companies like Transcend. But they're targeted for industrial applications and use relatively low performance SATA controllers.
It is no coincidence that Techcrunch loves writing negative articles about Uber almost weekly now.... It draws in page views which equals ad revenue from the constantly outraged.
the volocopter is a very cool project the problem is that will need a new legal framework kitty works on current part 103 regulation.
Also I don't belive the volocopter will work for 2 passengers at least in the next 10 years.
They went mass market is the problem. If this were for seniors it would have been totally acceptable.
I don't have the specific citations handy, but California law enforcement agencies are restricted in what information, and in what circumstances, they can share with regard to minors suspected of crimes.

This has nothing to do with limits on people in general sharing video or images of minors.

Uber can't seem to catch a break these days, can they.

Can anyone explain how this is different from Google and Facebook following you around with informatics everywhere you go on the internet? The favicon trick is a pretty good example.
I think a pure diff is going to give you too much noise and will be misled by simple mutations (I think..).

Here's an approach - after you normalize the docs to text you should then extract terms/keywords (google "term extraction" - there are libs that use POS to help) and save those as tokens. One approach would be to use something like elasticsearch to do a "more like this" filter. The idea is that you want to find documents that are most similar to a certain document.

I haven't tried this approach but if it's effective, it should be able to handle a million resumes easily.
Gramophone records. Audiophile speaker cables. Many (if not most) branded luxury goods ($2145 IKEA shopping bag, anyone?) [1][2].

These products are not made to be functional, any functionality they have is secondary to their prime purpose: to be used as props in a ritual. What ritual they serve varies, from the mundane 'I can afford to spend a lot of money on non-essential goods' affluence signalling (most branded luxury goods fit in this category) to something resembling the Japanese tea ceremony in the sense that they turn a common event into a highly ritualised happening (I'd fit gramophone records in here). Some are just ways for unscrupulous actors to extract the maximum amount of money from an easily duped audience ($21.000 for a 3m short speaker cable [3], anyone? Don't forget to buy that $11.000 mains cable [4] while you're at it, you would not want your $144,481.80 turntable [5] to be without it).

Cold pressed juice itself is probably partly ceremonial, partly affluence signalling. Where overpriced, waste-generating Rube Goldberg juice delivery devices with vendor lock-in fit in I'll leave for you to decide.

Sure. 2 points; I subjectively view this crine as much less admirable than a simple bank robbery or Ross ulbricht (less the alleged murder attempts) as this causes individuals direct harm. This is subjective, I think others may agree that identity theft is pretty malicious.

Also, yes Russia could kidnap you if you committed enough crimes for them to dub you worth tracking, capturing, negotiating a diplomatic extradition and then trying in court. Its not likely many "regular" people will be carted away from a Bahamian Vaca.
You are calling it a money grab. The only point I am making is that this is a ridiculous assertion.

You only know as much as the article states. From my experience paying claims, I don't believe that in any way qualifies you to make any meaningful judgments here.

Smoke inhalation can cause serious and long lasting damage. Being trapped in the car because they can't open the door can be a means to worsen that damage. Such damage is not visible to the naked eye. It is a better predictor of death in case of fire injury than the more visible burns.

But don't let logic or anything get in the way of your opinions.
That stops it from reaching a "false" consensus, but makes it easier to stalemate the network.

With a 60% consensus, 41% can deadlock the network. A deadlock of a financial transaction system is de facto control (if we believe Dune).

With a 50% consensus, 51% can deadlock the network, but have no need to, as they're already capable of voting their agenda in.

Any increase of consensus past 50% gives an increasingly small minority group the power to deadlock the network. Further, 50% is the magic point at which a minority can neither overrule a majority on consensus nor deadlock the network.

Deviation from that middle increases one of those two failure modes.
Well, if "all life should fall on the safe side of the line", what would you eat? Perhaps only organisms that have died without human intervention. Scavenging, I mean. But that wouldn't support very large populations.
Does anyone have more details on slide 9 "Proof of time: Modular roots"?

> In group of order 2^k, square k-1 times to find a square root

I don't want to say anything stupid, but I don't know if this is trivially true, for instance in [the multiplicative group of] a field of char 2, square is linear and so it's square root.

Edit: to clarify, in a field of char 2 the multiplicative group has order 2^q-1, which can't be 2^k. I'm just giving this as an example of a group where square root is fast.
Hipchat Hacked, User Data Compromised
I would prefer businesses compete on the services they provide to their customers, not on how effectively they can sneakily torpedo their competitors (by, in this case, trying to deny them their suppliers).
As far as I know, Bret Victor is looking exactly into that, check out his talk "The Future of Programming": https://www.youtube.com/watch?v=IGMiCo2Ntsc
It's still first class hypocrisy.
You'll have to normalize them to text to make it work - the format is not important for the deduplication (meaning the same text in a word doc or pdf is really the same thing to you, even though at the byte level the files may be very different.)
My Life as a Failed Artist
I had a gig at a company that used Hipchat once. I generally like the app, but I was shocked/appalled that posting files to the chat got uploaded to the AWS cloud with a URL that is retrievable anywhere. Do you know how often things like logs, config files, etc. got posted to chats? That place wrote insurance software too, so plenty of juicy financial information in their systems.
It's probably an unauthorized use of the API; Lyft's API is not public, and requires a separate agreement to use.

https://developer.lyft.com/docs/lyft-developer-platform-term...

One section I'd draw particular attention to reads,

"You Will Not: a. use the Platform or Service in any manner that is competitive to Lyft or the Service, including in connection with any application, website or other product or service that also includes, features, endorses, or otherwise supports in any way a third party that provides services competitive to Lyft’s products and services, in our sole discretion; ..."

So if Uber profited from that misuse, why wouldn't Lyft have a case?
