Awesome -- I find it rather fascinating not having to refresh myself and having the experience of seeing how posts gain traction. What technologies(frameworks)did you use btw ?
There are a few tactics but first consider the odds:

- First, the target would have to be a subscriber to Trim so that's a small group.

- Then you'd have to cancel something they actually have so that further shrinks the group. (Netflix would be a likely candidate.)

- But then Trim could thwart most attacks with a simple "Are you sure? If so, respond with " + rand(0, 100) If Trim used a simple Y/N the attacker could spoof that easily.

Spoofing a message from another number is relatively easy. Catching Trim's responses is more effort and most attackers aren't going to go to that level of effort.
The sales people don't have access to the content moderation systems. As far as it showing up in code, I was just making the point that there is no file containing something like

if business_has_paid_extortion_money:
show_good_reviews()
else:
show_bad_reviews()

... which is how people seem to think it works.

There is also no code to allow manual review ordering. They are sorted according by an algorithm with a variety of inputs including who you are friends with, who has Elite status, etc.
They're already insanely cheap compared to most competitors. This should take them to being ludicrously cheap.
> Why is Juniper using Dual_EC DRBG anyways?

As a follow-on question: was NetScreen using Dual_EC_DRBG before Juniper bought them (and with it ScreenOS?) If so, it might be good to scrutinize the original NetScreen owners and where they are now (hint: They now run Fortinet and Palo Alto Networks. Are they at risk of interesting, compromised security choices, now, too?)

And you're right. Juniper could still have their own e, which renders the security pointless.
Lyft is running cash-burning (not merely unsustainable) promotions in a select number of cities, most likely to try and impress prospective investors that "We have 40% marketshare in NYC!".

Pretty meaningless when that's the result of a 50% off. Meanwhile Uber has been cutting back on promotions and incentives.
Because the Falcon 9 traveled at several thousand miles per hour horizontally when it did its flip and then the first retro burn. By contrast, the Blue Origin rocket went straight up, and straight back down. It never moved away from the launchpad in any appreciable amount and it never had to change orientation. From a space applications perspective it is not much more useful than a blimp.

Today, history was made. Blue Origin: not so much. Nice but nowhere near in the same league (or the same club, to stick with Bezos).
>a home in a walkable area will often command a 1.5x to 2x price premium over a similar home in a typical car-centric suburb.

I suspect this has more to do with fact that walkable areas are much more likely to be located in city centers with higher overall real estate prices than with the desirability of walkable neighborhoods.
But the F9 first stage doesn't get to orbital velocity, either, remember.

The achievements are comparable, despite the fact it makes SpaceX come second. Blue Origin was first with a VTOL rocket stage, as part of a space system.

I don't think unreasonable in the context of this discussion.

When we use English, having a bit of miscommunication is likely harmless, and probably goes unnoticed most of the time. When we write a computer program, we really want the compiler to understand exactly what we mean.
That's pretty much it. As I understand it, the difficult bit was landing your rocket safely after launching it 100km up.
It is alot of work to keep up. I would use KairosDB instead. https://kairosdb.github.io/.
Thanks; year fixed.
I disagree. There are a lot of people out there who are interested in space but don't really understand it. Just one anecdote, I spent twenty minutes explaining the difference to my father after BO's landing, which he genuinely thought was beating SpaceX to the punch.
Majority of Mobile Apps in China Don’t Retain Users for More Than a Week
Absolutely. Thanks for sharing!
If we downplay the difference between the landing modes and vehicle's missions, then SpaceX has beaten Blue Origin anyway - they had Grasshoppers doing VTOL years ago. After all, what's the difference between 700m and 100km, especially if in the latter case you're falling at terminal velocity for most of the way?

I get the impression that MVVM only really works well when you have robust data-binding support baked into the framework (e.g. WPF/XAML). Otherwise you end up with a bit of an impedance mismatch and a lot of overhead in keeping the views synced with the view model.

For example under iOS this probably means going all-in with ReactiveCocoa. But I'm not convinced that completely switching paradigms like that is the right way to go.
Let's see who tries to imitate them and do a re-use, some real competition is what's needed next.

Now for second stage re-use ;)

Is there reason to think that bacteria with every gene for antibiotic resistance would be at all viable? It seems likely that these genes have other negative effects on fitness that make them unlikely to spread significantly in the absence of the antibiotic.
For violin, I would recommend placing your horizontal guide lines to correspond to a just scale rather than 12-tone equal temperament.

Another type of tuning visualization that only works with just-tuned instruments is to have something like an oscilloscope, with the vertical axis connected to a microphone or pickup and the horizontal sweep set to be the same frequency as the root of your key. An interesting thing that happens is that, for any note that makes a whole-number ratio with respect to the horizontal sweep rate, you get a standing wave. If it's drifting to one side, it's sharp, and if it's drifting the other way it's flat.

I experiment with just-tuned guitars, and this is what I do with an old analog oscilloscope to check if my intonation is right.
It's shock humor. Whether you perceive it to be subjectively funny doesn't affect how others see it. You could call it childish, but it's still a joke.

Lots.

There's really not a lot of costs that can add up for reuse of these stages. It'll require a bit of cleaning up, a few new bits and pieces replaced and added, and a lot of inspection work. But most of the cost of the stage is in manufacturing the engines and tanks, so it should add up to enormous savings, even if it's relatively costly to reuse each stage compared to the theoretical limits.

Edit: the flip-side is that the reliability and robustness improvements from reusability may be as big a win as cost. Currently it costs tens of millions of dollars to launch a rocket to orbit, which means it's almost never done except as part of a paid launch. Moreover, despite the seemingly high number of launches very few of those launches represent expanding the test-envelope much, every single launch is typically straight down the middle of the performance envelope, to maximize the chance of success. That results in learning very little about these vehicles despite how much they've been flown. By introducing reuse and dropping the cost of flight it may become possible to do real test programs, which would make it possible to determine the flight envelope characteristics of vehicles and help lead to improving designs over time.
But they're not all moving at the same speed if the second stage was still firing between satellite releases.
How is BO's achievement different from what SpaceX did with their Grasshopper test vehicle years ago?

If you want to say it's about VTOL rockets, SpaceX was first by a long way. If you want to say it's about reusing an orbital launcher, BO is nowhere close. You have to torture the categories into uselessness to say BO did anything first.
Can confirm. I commute between Herndon VA and Greenbelt MD every day. If I get on the beltway before 6am it takes about an hour. I would love to ride the Metro rather than drive, but that takes nearly two hours.
There have been several recent threads about the Vulkan API: https://hn.algolia.com/?query=vulkan%20points%3E10&sort=byDa...

The current article falls in the "announcement of an announcement" category, which is basically always fluff. If the release is imminent, we can have a discussion when it exists.
But you can use it to grow space potatoes! :).
Well, if you do, let me know. I'd hit it especially if you get a MUD or two up and running, although that might be more than a 64 or 128 could handle. ;) I have a "museum quality" C64 with an Ultimate II cart for storage, but also a 1541, 1571 and 1581 so I can read disks for you if you want to go snail-mail. A lot of disks can be transferred. I also have a "never used, never sold" Amiga 1200 (which I do indeed use) that I've been beefing up, since I can... CF HDD, extra RAM.

I haven't put either online yet even though there are ways out there. But if you got a BBS going, I'd partake in that. There just isn't anything out there. Everyone has moved to forum software these days (and places like HN!).

See my profile here on HN if you ever want to get in touch.
1. Things like graphql for rest apis will be the standard. There will be more mature languages and tools than ever to choose from. Swift will see some uptake as a web language.

2. Competition will disrupt JS as the only front-end language.

4. Skynet.
> But the F9 first stage doesn't get to orbital velocity, either, remember.

It gets a whole lot closer (and is _much_ larger).

I really can't emphasize enough how much of a difference the ability to hover makes for New Shepard. SpaceX has been doing "New Shepard" type flights for a long time now (they didn't bother going that high, but 'high' isn't really that interesting, it's 'fast' that matters). However, Grasshopper (like New Shepard) was able to throttle down to a TWR less than 1. That makes landing so much easier (the rocket can 'stop' and get settled before it proceeds to land).
"but rather in a direction that is beneficial mainly to a small incumbent minority."

The majority of C programmers seem to fight changes to the permissive way of doing things in name of efficiency and compatibility. I don't know what the interplay between them, compiler writers, and standards bodies is. Yet, it seems C programmers react pretty negatively to anything changing their language even here. Just imagine how much of UNIX or GCC might break if we did pre-fixed strings, a reversed stack, compiler-only pointer arithmetic, auto-bounds checks, and so on. It would all just... COLLAPSE.

"yet it is virtually impossible to write secure code in C or C++, not because it would violate the laws of physics or some mathematical theorem, but because both the standards and the implementations are hopelessly brain-damaged."

Totally agree there that this is what resulted. Recently, on a new platform, I needed to code up something that C programmers can read and I can't remember C worth crap. So, I decided to re-learn FreeBASIC cuz even it's easier to get right than C & I straight up can't stand C. Coding style wasn't... modern... but worked, was type-safe, iterated fast, ran in milliseconds, and was very readable. Stuff I can never say collectively about C without state-of-the-art tooling on 4-8 core machine with RAM disks. ;)
At any point since bitcoin's inception there have been plenty of major govts that could have easily afforded the resources to pull off a 51% attack.
True but irrelevant, as the second stage engine cut off before satellite deployment.

> Eating a factory cheeseburger is akin to racism? Seriously? This is a logic fallacy.

Do you realize that there are several religions that hold this exact tenet? And that it's one of the central tenets of Rastafari?

Maybe these people all live their lives based on a logical fallacy, but I don't think it's so far wrong. Both racism and factory farming come down to disrespect for 'the other.'

> Racism comes from the individual.

Most people who study racism regard it as an institution, separate but related to bigotry, which is a quality of an individual.

> I'll also point out that the only way to real change in gender and race inequalities have come about is through government or self-regulation in industries... the same thing I'm arguing for when it comes to the agricultural industry.

Go propose a talk at any Black Studies department in the country with this as your thesis and let us know how it goes.
> gcc's project steering is philosophically opposed to allowing non-free (as in GPL) plugins

I think that's the right philosophy. Why shouldn't you be contributing your plugin if you derive value from it, so that other people can derive value from it just as you did with GCC (if you distribute it that is - if you wrote it inhouse for internal use, then it doesn't matter at all!).

It's not like the code generated by GCC is licensed virally.

It's a shame that GCC's code is hard to modify, and difficult to extend. LLVM's permissive license means that contributions don't flow back unless it's favourable to the entity contributing it (such as good PR). I imagine that if somebody/some company wrote an excellent, non-obvious, non-trivial toolchain using LLVM, derive profit from it, they will not _want_ to contribute it back.
No I am not. It gets brought up every so often as the most rational approach, but those who have climbed the greasy pole of the current system, and hence control it, are none to keen to change.

The usual argument against a lottery is it does not reward the best scientists and will give grants to third rate hacks. This is true, but it can be solved by having different lotteries with different thresholds. Publish one paper in the Journal of Useless & Pointless Results and you go into Pool A where you might have a 0.1% of getting a grant. Publish 20 articles in Nature and Science and you go into Pool H where you have a 75% chance. We would just need to be careful that we are not recreating the same perverse incentives that the current system encourages, but this is not insurmountable.
I guess it's like Hilary and Tenzing being the first to climb Everest, and then someone else (can't remember who it was) coming along and doing it without supplementary oxygen. Just because that was harder doesn't detract from the fact that Hilary and Tenzing were first and anyone else is just joining the ever-growing club of Everest summiters.

Now, if you want to invent an extra category of 'first VTOL landing for a first stage booster for an orbital rocket system that uses boost-back to change trajectory mid-course' or similar, they SpaceX are first with that, and of course it's an awesome achievement.
If you look carefully at the YouTube live streams, you'll notice you can scroll them back all the way to the beginning - the "live" part is always at the very end :).

EDIT: and here's just the landing itself: http://www.gfycat.com/WeepyCelebratedAfricanaugurbuzzard.
"what the rest of the system does has no real part to play in the landing of the rocket stage"

That assertion is ridiculous. The rocket is optimized to do one thing, push it's payload into orbit, this is a very strict restriction, especially on a two stage rocket. On the other hand, the designer of a suborbital vehicle has ample design space to play.

It's like comparing your practice free throw, in your back yard, with a slam-dunk in the NBA.
If people eat factory farmed meat, they are acting in a shameful way. If they don't feel shame, they have no shame.
Malice isn't enough. The only special power of a 50% miner is to consistently resolve double-spend attempts in its favor. If this happened, it would surely lower the value of Bitcoin. This, an attacker must be not just malicious but also irrational enough to forfeit the $800,000 in Bitcoin that it creates daily by virtue of its 50% control of the network. (6 blocks/hour x 24 hours/day x 25 bitcoin/block x $450/bitcoin x 50%)
Well a miner like the one going live is also responsible for managing the transaction volume. So the capacity of Bitcoin to manage many more transactions just went up.
"Destroyed" is an unfortunate term to use. The drivers and riders will benefit who are predominantly not rich, so its actually a kind of stimulus.
Did bad design cause Miss Universe screw-up?
Agreed. Loved the data feed on the video. The tension built up as the indicatior neared the "landing" hash mark.
It almost sounds like you are talking about something like SETI@Home...
I don't see what you're seeing. There are lights surrounding the landing pad. Are you talking about those?
There is of course the issue whether you want the compiler to do that. Usually optimizing one parameter in a design to the exclusion of everything else is an strong indicator that the engineers involved are functionally incompetent.
If SpaceX is so much cheaper than everyone else, how come they launch so infrequently. Seems like they should be launching every month but they are nowhere near that.
It does specifically because it increases the barrier to entry. This means the likelyhood of an attack is lower and the cost of an attack is higher. If your Rasberry PI ledger had a market cap of multiple billions of dollars, the likelyhood of an attack that would either steal people's money or shut it down would be pretty much %100.
When I moved to France for a semester I had to make a fb to keep in touch because I didn't have a phone. Until you get yourself established in places it's a very easy way to keep in contact with people and make new friends regardless of what you're used to in your home country.

There's an interesting book on the economic underpinnings of Bitcoin-

https://s3-us-west-2.amazonaws.com/chainbook/The+Anatomy+of+...

> we now know that there is a near precise
model that describes the cost of running and maintaining the network. The way the
cost estimate is determined is through how Bitcoin acts as a decentralized waste heat creator
that activates and deactivates heat generation based on market participation and pricing
signals. What do the randomizations necessary for cryptography and the waste heat produced
by computing devices have in common? One word: “exergy,” a term of art describing the
maximum useful work possible during a process that brings a system into equilibrium with a
heat reservoir. Exergy is always destroyed in the seigniorage hashing process - for example - if
a token's value increases to $1,000, this means that at most $1,000 worth of waste heat will be
generated somewhere in its creation.

From my reading of the text, it's not so much the additional hash power that's valuable, it's the additional money spent building and operating the ASICs. In theory, the market cap of a proof-of-work system should approach its total cumulative cost to secure. The more watts you see being dumped into the environment calculating hashes, the more you should value Bitcoin.

If Bitcoin is worth less than its cost to mine, no rational miner will mine (if they want BTC they'll just use their electricity budget to buy it on the market), so the competition (and therefore the cost) to mine each block goes down. If Bitcoin is worth more than its cost to mine, mining becomes profitable to anyone willing to put up the capex, so the competition (and therefore the cost) to mine each block goes up. There's an equilibrium where the value of Bitcoin is equal to its cost to mine.

The actual price of bitcoin as seen by the average consumer is insulated from the cost to mine because of effects like speculation, perceived future movement, and the value provided by ease of spending / anonymity, so the economic theory isn't really accurate, but that's why it's a theory!
Item number 1: SSL is obsolete, use TLS.

Can we please, as a society, try to move forward with the correct acronym? Everyone who isn't wide-open-vulnerable is using TLS 1.0 or newer. (Personally, I like to run TLS 1.2 only, but my CloudFlare domains still speak 1.0 and I can't turn it off without paying money.)
For development, having full access to the AST at will is a definite good reason. Having such allows you to analyze your code as you're writing it in much more intimate ways, allowing for better refactoring tools, better error analysis, better variable completion, etc. Additionally, because of the modular format of clang, pretty much every build is a cross compiler. You don't need to rebuild clang to get support for arm and x86, for example. There's even targets for GPUs, so you can use the same toolset top to bottom much more effectively.
Depends on the procedure they ultimately decided to use for the prep. Originally the the shuttle main engines had to be taken apart, with every part inspected before the next launch. If they have to do something like that there's not much point.

But if they can get it to point where it's a matter of gassing it up for the next flight, that's a huge savings. Fuel is a few hundred grand for a rocket that costs sixty million dollars. It's nothing, basically.
> How would bitcoin's power consumption stack up if it were tasked with servicing tens of millions of transactions per second?

It would stay almost the same since the hashing power is not connected to the number of transactions.

Also by the way, no one does tens of millions of transactions per second, visa does something like 40,000 at their absolute peak.
I was referring to idiopathic gastroparesis. Given that stress affects vagal tone (which is implicated as the cause of gastroparesis), and given the 10:1 female:male ratio (similar to fibromyalgia), stress seems a plausible cause for temporary idiopathic gastroparesis.
