Neither of your first two paragraphs are correct. I don't have an opinion about the last.

First: while I don't know what you mean by "teasing out differences with respect to various oracles", the fact that you have a kernel CSPRNG that your system relies on means that diversity in CSPRNGs is a bad thing. Simply: alternatives to the LRNG lead to multiple single points of failure.

Entropy is not "scarce". In fact, it's infinite and renewable. To generate a practically unbounded number of random bytes from just 16 bytes of starting state entropy, just use those 16 bytes as an AES key, and use it to encrypt an incrementing counter.
I knew someone was going to say this. In fact, the last sentence of my comment was added in an edit after this rebuttal occurred to me. Yeah. Dunno. Definitely don't slowly permute your CSPRNG state one bit at a time.
>And Xp feels fast too, it wasn't, 7 was faster, but it felt the other way.

Desktop composition adds a frame or more of latency. If you disable it (sadly not possible in Windows 8 and later) UI interaction feels noticeable more responsive. But most people run Windows 7 with composition on, so for them it makes sense that "XP felt faster"

There's some confusion here about dual licensing projects. Maybe an internet lawyer can comment. The most successful project that I know of that uses dual license is qt which offers a GPL license for open source and a $500+ per month license without restrictions for commercial. Some people say you can just link dynamically and include instructions for how to relink yourself, but if that's true why would anyone provide qt any money, especially at $500per month or whatever rates they charge.

PayPal suffering from a MAJOR subscription processing bug
As someone who moved out of SF 2 years ago, this article reflects exactly the frustrations I felt with the city. I'm all for progressive ideals. I support universal healthcare. I support free higher-ed. I support basic income. And I'm perfectly happy to pay drastically higher taxes in order to fund all of the above.

But I also want to live in a city where I don't need to worry about my car getting broken into. Where I don't have to worry about being mugged late at night. Where the police department is adequately staffed to minimize crime, and those who do commit crimes are punished for doing so.

And call me an elitist, but I'd be very happy if my kids could grow up in a city where the streets are clean and don't smell of piss.

I don't see why any of those desires should be in conflict with my progressive ideals, but apparently in SF, that makes me a heartless capitalist pig. Whatever. Water under the bridge now. Best wishes to you SF. I'll just continue living here in my new home where people are willing to face up to real problems with practical solutions.
Apparently NYC is trying...
Not to /dev/urandom, AFAIK. But at least they have the new getrandom syscall.
Does anyone have a good resource on this family of languages or otherwise on any of them individually? Every time I've run across references to K/Q I've poked around a bit and it feels like they kind of exist as linguistic curiosities in some vacuum with a vaguely unexplained creation myth about a man named Whitney.

Edit: found this paper which appears to be around the birth of array languages by the developer of APL.

I'm not claiming it would be cost competitive with current jet fuel prices. However, if fossil fuel prices skyrocket (either because of a substantial carbon tax or simple resource exhaustion), then the economics change in hydrogen's favor.

I'm also not claiming that existing airframes could be easily retrofitted to fly on hydrogen. Not only do you need a much larger fuel volume, you can't practically store it in wing tanks. On the other hand if you took an existing design and stretched the fuselage to accommodate larger tanks, or attached large external tanks to the wings, you could get something that's economical. That's because you have an aircraft that's larger (more expensive, all other things being equal) but also lighter (cheaper, all other things being equal).
There is also a class at Stanford that builds up all the theory of the Kalman filter, starting with elementary probability [1]. The slides are all posted, and while they wouldn't be great to learn the material from, they're an excellent reference (and go into more depth on multivariate Gaussians and estimation theory than Probabilistic Robotics).

I got exposed to kdb+ while interviewing in quant and would kill to use it in a non-financial metrics setting, but the language and ecosystem just can't let me get there. kdb+ is so fast and powerful you'd think it impossible.

They're not directly comparable, but kdb+ would crush InfluxDB head to head in an apple/orange comparison if used for the same thing. I actually can't think of any time series-like store that remotely comes close to the feats I have seen kdb+ with Q accomplish. Too bad the productivity and knowledge overhead is so high.

Seriously, I'm working in realtime metrics right now and I spent a week playing with kdb+ as the central store. I can tell there's a gold mine there, but I'm just not swinging a big enough pickaxe. If there was a dumb Python/Go/etc typical ops hacker frontend to that whole system I would be throwing every dollar I have to my name at it; my kingdom for burying that system under a few layers of abstraction and paying some quant Q hacker a Ferrari or two a year to hide the sausagemaking from everyone else.

(Related aside: Like building furniture from stacks of cash? Learn K/Q/kdb+ and head for NYC.)

A lot of merchants including us are having the same issue. As usual paypal's support sucks. I notified them about this a few weeks ago when it first happened to us, and the "support" guy said something like:

"Sometimes things like this happen on websites"

I suggested he report it to the dev team, but I guess that didn't happen. It's hard to know if paypal even knows about it, as they don't seem to have a site status page. (There is paypal-notify.com, but you need to log in to even see the status, and I can't be bothered investigating to see if it is actually a legitimate paypal site rather than a scam site).

WTF paypal!

I was just looking at alternatives. It seems stripe is about the only alternative that supports subscriptions, but a lot of people are saying their support sucks balls as well.
I've used Skeleton in some projects while I was contracting. I've moved on to Milligram.
+1. As someone who has worked in the field of information theory, I strongly dislike the abuse of its usage here.

Funny that the term "information theoretic" is used with not even one "theorem" in the linked document.
I still have a Softway Systems CD laying around somewhere. Wasn't quite the same as Linux but was fun to play around with.
Linux the kernel yes. but Linux user space is notoriously against dealing with backwards compatibility.

As for Windows, best i can tell the problem was Win16 on 64-bit Windows. My father ran into that regarding some old solitaire programs he had been keeping around.
Unless they of course they read the news, which is something that seems likely.

... which, of course, was the original point.
Yeah. This has been something they've been looking into for a while now. Read all of the updates. It's turtles all the way down.

I have the same sentiment. I realized that it is not really Vim, the editor, that I want. It is modal editing.
It is probably time to eliminate bikes from the list of things that can be considered "property". It should be illegal to lock up a bike or "own" one.
What proportion of that 27% comes from taxes collected from Londoners?
Nobody is advancing pathological one bit starting entropy cases. Of course you need entropy. But you don't need thousands of fresh bits every millisecond. You need a few hundred once.

More important: nobody knows if the entropy counter is truly conservative, because nobody knows how to properly count entropy. Linux makes educated guesses by assuming a model of entropy for the inputs (inter-arrival times of events). That's far less solid than the rest of the random subsystem.
A break of SHA1 (ie SHA1 preimage oracle) breaks u/random. This is less secure than something that is broken if SHA1 and SHA2 are broken. But since there are no known full breaks of either, this is "merely" hypothetical.

We can define our measure of entropy such that the output of AES (/SHA1) qualifies, or such that it does not. The way it is used in the random/urandom distinction, it's clearly not meant to include PRNG output.
I don't think so. In the terms of "random that does not follow a known deterministic algorithm or formula", both chaotic sources like lightning strikes, and quantum states, like photon spin, can be so random, that for all definitions of "truly random", they fit the bill.
For 99% of the coding I do, I use an IDE which is usually Eclipse. Though I like IntelliJ more, I just don't have the resources to pay for it where I work. That said, I do drop to vim for many things, mostly editing conf and properties files, stuff where the advantages of an IDE don't really play.

However, I've felt for a long time that most modern GUI based applications and windowing systems lack a truly comprehensive and slick way to navigate using the keyboard. And let's face it, that's what "power users" like about vim and the command line in general.

There are lots of keyboard short cuts for Eclipse, Visual Studio, and pretty much most popular GUI applications - the shortcuts just suck or are poorly documented - or both.

I find navigating with a mouse or trackpad to be cumbersome, slow, and inexact. A well though out keyboard based UI would be a welcome addition.
So morning star would be the weapon of choice there I suppose. Sword may win "by points" but with morning star you'd have a solid chance of actually neutralizing opponent.
I used vim daily for 15 years and I recently switched over to Atom. The reason was that I felt like I was handcuffed to my custom vim configuration. My ability to write code quickly was coupled to my editor configuration. Even vim bindings weren't enough in other editors due to the muscle memory of the custom bindings I'd built up over the years. Within a couple of weeks I was comfortable in Atom. I still miss some of the conveniences, but ultimately I like being able to pick up and start developing anywhere - without pulling in my dotfiles first.
It's a quiet kind of suffering. Solidarity.
NewsBlur doesn't have as large of a community as Reader did, but it has similar social features and I find that comments are generally high-quality. I recommend checking it out if you haven't found a good replacement for Reader yet.

(Suggested as someone who was similarly disappointed at the death of Reader. I tried a couple of alternatives but eventually settled on NewsBlur.)
New York strikes a more sustainable urban balance than San Francisco. We embrace social programs, but not at the expense of quality of life or development.

A lot of the balancing comes from development. It's rare for e.g. a city block to come together to demand better policies. When they do, it's often a NIMBYist backlash against productive policy. Developers, on the other hand, care about the impact of policies on their aggregate holdings. Since they're typically developing a pipeline, their NIMBYist instincts tend to be relatively dulled.

Everything seems to point in the same direction. Cities which refuse to grow, instead transferring the fruits of growth to a land-owning elite, fail.

Awesome to see some Kalman filters! Takes me back to my undergrad :-)
I bet you live in the Bay Area? Specifically, the east bay? Near Berkeley?

There's a two well known flea markets where bike thieves sell their stolen property. Even if you are at the flea market, with you bike's serial number in hand, the cops do not come out.

A huge guy, who had his bike stolen once too many times advertises in CL. He will literally show up at the flea market, and take your bike back, after you show him the serial number. (Guys like this do not get enough props. He does it because it's just the right thing to do.)

I have never used his services, but have had bikes stolen. I've literally given up. My bikes are now pretty much throwaway. If they are stolen, it's no big deal. I want to buy a motorcyle this summer, but theft is first feature on my mind.

Would I prosecute a bike thief? If I felt they were professionals--yes. If, I thought it was a yuppie, who gets a rush out of stealing--yes. If it was a homeless person--no.

I saw a great deterrent to bike theft at Target. Outside the store they had these little pods you put your bike in. You supply the lock. They take up too much room for most businesses though, but they look like you could stack them two units high?
I meant more the part that we should be deferential, rather than try to influence politicians to make law enforcement not be above the law.
I think get this now - with SOAP/RPC/REST we can establish the interaction contract by explicitly defining inputs and outputs. With that contract, we can draw clearly defined system boundaries, give better assurances to the developer that they are doing the right thing, and improve testing.

You're right - in the scale of app-level problems, GraphQL is just a low-level protocol. It requires language-specific libs to address these higher-level problems (provide interfaces, structs, query typing, etc). As a very basic example, programatically building a GraphQL query is unnecessary complex outside of JS because many languages don't yet have a QueryBuilder for the GraphQL syntax. There are some community efforts, but as of yet no heavy corporate players to drive GraphQL-specific dev (e.g. like Pivotal/Sensio/Sencha did for their respective fields).

"So even if her telomeres did get longer, how confident can we be that is at all related to the gene therapy?"

Because:

1- They got radically longer in only 12 months since the delivery.

2- There are previous studies backing up the claim, in rodent and in-vitro models tho. Read the links in this thread.

What we are witnessing is only a bypass of the standard trials process. I do not share the method, too risky, but there's undoubtedly substance.
Radioactive decay is slow, slow, slow. There are much better performing sources of randmness, such as beam splitting.

Further, not all noise is RF-based. Thermal noise, for example, is not influenced by RF intereferrence.

My biggest issue with this was that it is purely event driven. So what if your trying to alert on no event? They had no answer for that
> ... which, of course, was the original point.

Right, which explains they they were reluctant to put it in the news i.e. "... but they won't say because they don't want to alert the guilty party before the investigation is over."

So it doesn't seem completely illogical why they'd do it as gp post suggests.
The card is the actual assignment. We understand that not all students have a computer. However, we are finding that most have a smartphone. The assignments and digital portfolio are easily managed via the mobile app.
It sounds like the demand for is juice low due to sugar labeling requirements. The demand for the husks is high however and the left over juice is a byproduct of harvesting the cranberry husks for craisans.

So what is the right answer? Dump the juice in the river? That's like throwing away money since it seems like someone is willing to buy it.
It's a nice product, just be aware that it is purely event driven. So if you are trying to alert on no event then things get messy
I don't think it's obvious that you can't tell whether someone has free will from the outside. Considering the enormous success physics has had with explaining every other phenomenon from the outside, that seems like a very strong statement.
He says that this is an inefficient way to generate the nth Fibonacci number, but since it actually gives you the first n Fibonacci numbers, thats not the fairest comparison. (Especially since the fastest methods for finding the nth Fibonacci number don't generate all the intermediates.)
Just for curiosity sake, how does using this formula to generate all of the first n Fibonacci numbers compare to other ways of doing that?

(You get all n with the same formula by replacing the mod 2^(n+1) (or reading the last n+1 bits) by splitting the whole integer that is generated into n+1 bit chunks.
You're most welcome
I like this dramatic videos from Russian Vyborg castle, I wonder if they still organize these:

The bug report is not wrong. Rather, whether the current behavior is correct depends on the platform.

For example, Darwin's libc offers this contract for memcpy and clang is perfectly within its rights to generate such code (note that the IR it generates is still violating LLVM's contract on the memcpy intrinsic); glibc offers no such contract for memcpy, and so clang's code is nonconformant.
It's odd that the article avoids the question of where crime occurs in the city, as that might provide some answers. A few months ago I made many data visualizations of where criminal arrests occur in San Francisco: http://minimaxir.com/2015/12/sf-arrest-maps/

The tl;dr is that, as expected, SF crime is centralized in the Tenderloin, with 16th St Mission being a close second. However, as the years progressed, crime has become relatively less centralized around those areas. (there wasn't much activity on Lombard Street, though.)
Some countries are already implementing that - for example, in Portugal, the Citizen's Card is a smartcard with a private/public key pair, signed by the issuing department, and which one can use to login to certain governmental sites (like the IRS) and to sign documents. I hear Estonia has a similar system.

While I think it's a good idea for services that already required official documents (governmental services, bank accounts, certain utility contracts), I fear that once the system is actually used by most people - right now it's still mostly ignored - more and more services that were once somewhat anonymous will start requiring the card, since the barrier is much lower than having to send an authenticated photocopy.
> It's incredible how closed off they seem to be in general

It's not surprising if you think about the difference between free speech and having censorship laws that limit peasants. I learned that when I first traveled around Asia.

Your ability to be creative is limited in China. People there can't make art that makes fun of Mao. They can't protest against local police corruption. They can't form groups that appear to be anti-government. For all of this you can be tossed in jail for a few days. Jail is demoralizing and disruptive.

If your contribution to society comes through speech that the government does not like, you'll be put down. You'll end up less willing to contribute to society than Americans who hate their bosses. Instead of a bad boss, it's a bad country leader, and that's much much harder to get out from under.

I suppose one day everyone in China could just decide to go to jail peacefully; that would be unmanageable for the government.. it could take a lot of noise to get that message out and there is some risk of violence. Police sometimes see themselves as judge and jury, and in China where speaking can be against the law, violence against peaceful protesters is not unheard of even in 2016.

Before I came to Asia I did not think much about free speech. If you asked me what made America great before I moved here, I'd have said it's complex. I wasn't even sure America is great.

Now I would say it's more simple: true democratic governments are not allowed to throw people in jail for speaking their minds.

The first step China can take towards sustainable economic growth, better research and education, is to prevent the government from imprisoning people for speaking their minds. You really need as many people thinking creatively and working hard as possible in order to be competitive. Society is about working together and digging out the best ideas. It's not about silencing people.

Until then, expect to see the most intelligent Chinese continue to leave to live elsewhere, pollution to rage further out of control, and free countries' companies to come and go from China. China's judicial system is worse than the free countries' for the same reason.
> “We are not going to criminalize people for being poor,” he said. “That criminalization is only going to make it harder for them to get out of poverty.”

No, but we should criminalize people if they commit crimes. Laws exist for a reason, and they must be enforced to be effective.
That may be true, but I've found that I grew up making mostly the wrong friends, each of whom was more irritating, status obsessed, narcissitic, etc as life went on. Only like 2 people made it through the filter, and I'm making healthier friends these days, but I say the ease of disconnection in modern society is a blessing, not a curse. Shitty people get left alone? Fine with me lol.
Nice. When I was a teenage self-taught programmer, an article like this one, but about the superiority of quicksort to insertion sort, was the trigger that got me to understand that thinking mathematically about algorithms could lead us to a kind of understanding that transcended mere coding (although I couldn't have put it in those words at that time). It was quite an epiphany.

I can imagine, today, a young enthusiast having learned Python and maybe done a few Project Euler exercises, stumbling upon that post and being amazed that you could generate Fibonacci numbers that way, and thinking that maybe there is something interesting about that "generating functions" thing.
