Concurrency: you have at least two threads sharing control of one CPU. Only one thread runs at a time. There is no parallelism. The important thing is that multiple threads are running.

Parallelism: the two threads are running simultaneously on two CPUs. There is concurrency too since there are multiple threads.

This was my favourite course at UNSW, very intense but that's also what made it fun! Many nights spent debugging race conditions and bugs till 4am.. The OS courses at UNSW are all pretty great.
Breakthrough for quantum computers
To be clear, the reason it is hard is the grueling pace of the project.

And to be honest, most of the individual tasks were not hard since this was a follow on to another OS course, but Milestone 6 was where shit really hit the fan for me when we needed to implement on-demand paging, and everything was easy enough in user space (catch fault, get the page from disk, map it into memory, restart the thread), but dealing with paging in an event-based kernel where you can't take a fault was pretty painful (where syscalls had a memory component) and resulted in some ghetto memory pinning.

So while this course wasn't really covering much new ground compared to the OS course we had already taken (I do recall some new material about how caches work and when you need to flush them, but not a lot else), the experience is definitely seared into my memory and I remember the details of that project like no other.

EDIT: To be clear, the lectures had a lot of new material, but it was not in the project, and .: not really tested. It did teach us about how things like VMs work.
This is very true. But, we have set up a market in the form of software that can potentially generate billions of dollars with human energy being the primary expenditure, ideally using existing hardware and energy infrastructures to build off of. If we can push software further, generate the revenue needed for research and projects like deep space exploration from this, we can still get there. It's not exactly "money from nothing" but it's as close as we can get, and we've already built the infrastructure to achieve it globally...

I've lately spent a lot of time trudging through 10-K's and financial data, so this is really cool! I've almost made this exact service myself on a number of occasions but stopped due to the unreliability of XBRL, which meant that even if I had a sweet API I'd still have to go back and double-check the numbers by hand.

It's because your question isn't really properly formed. What do you mean by "health"? The chance of a person having a really shitty genetic disorder? The fitness cost of inbreeding as a function of coefficient of relationship? The probability that a bottlenecked population will go to zero due to harmful mutations, as a function of the bottleneck size?
Strange, the chart doesn't go before 1950, we would definitely see a huge spike in the 40s.

Government grows with GDP because people want more services, less crime, less poverty, and stuff like that; there is a reason libertarians can't get elected.

One thing people like is going to space, having scientists trained in public/private universities. Even if they go into private industry, they are trained with lots of federal dollars. Cut off all that, and China will just pass us in a decade or two.

And really, why not spend additional GDP on public R&D? The benefits have been net positive over the long term, spurring new industries and economic growth. This is a no brainer.

I found httpie last week when I started to think I should write a replacement for curl with a much better UI.
Scrapping the guarantee that destructors will be called is tantamount to scrapping RAII. thread::scoped made the assumption that destructors were called before a borrowed value was returned, and it led to a memory-safety error. If you don't use unsafe, you won't get memory-safety errors, but you can get plenty of other nastiness.

The guarantee that destructors are called when values leave scope is fantastic. It means that one can leverage memory-safety into arbitrary-resource-acquisition-safety. It violates the principle of least astonishment in a brutal way if Rust's borrow checker can statically guarantee that a value no longer exists, but can't know whether or not its destructor has been called.

In that case, you have proven X by contradiction. If you're rigorous enough, you can rule out the 3rd option. As wondering if you're in a situation where your axioms are inconsistent, well that's actually the world mathematics lives in. Godel's Incompleteness Theorems show that, besides some weak axiom systems, the only systems of axioms that can prove they are consistent are the ones that are inconsistent. So we can only tell when systems are inconsistent, never when they are consistent. You just kinda hope it's not all inconsistent.
I'll reply to everyone at once here since the same concern for the most part is being conveyed. 1) Regardless your personal definition of "pedophile" or "terrorist" I believe there are crimes that a solid selection of persons across humanity can agree are not acceptable. But I realize there is no universality of beliefs, so I will be flexible here. I'm actually not saying you _should_ cooperate with law enforcement, only that, accepting that the law is _supposed_ to be upholding human decency, then we _ought_ due to moral responsibility help them. But... 2) if we do that, must we also sacrifice anonymity and the right to privacy? All the examples below illustrate that what we ought to do can often get us harmed; so the solution? 3) Vigilantism on the part of conscientious Tor operators; that is, boot the offenders, release the data to the public that they are trying to keep private, and let someone else deal with them. What, you believe that some sacred law among the cyber underground has now been broken? In prison, they kill pedophiles. This is not snitching but a combination of self-preservation (getting law enforcement off your scent) and universal justice (because there must be crimes "we" can "all" agree aren't conducive to a healthy life, a progressive universe and the continuation of the species as advanced.

I would suggest that one of the reasons so many people use Redis as a message queue is because they do not want another piece of infrastructure. The fact that people use Redis as a message queue does not, in my mind, mean that this is for lack of proven alternatives. I think this is a cool project, but for me, I will stick with Redis.
Double Zero-Day Trouble for WordPress
Oh boy, here we go again. Seriously, I even thought this had some potential. Obviously, as stated in the article, "Earth has natural processes that absorb and hold onto heat to counteract that cooling effect". However, the author slides to the wrong side. Without what has been called "greenhouse effect" (which should always be used inside quotation marks) to -387ºF at night. But the "blanket" that covers Earth is the atmosphere as a whole, regardless of its chemical composition.

Those "positive feedback loops" and "runaway greenhouse effect", such are "big words" they like to use, are speculation from (far from perfect) computer models (video-games). It is even admitted they know nothing about clouds.

What surprises me is that the author has the answer: "our carbon dioxide emissions wouldn’t be anything to worry about".

One thing they are right, though, even though they interpret it wrong at some points, it's the water, stupid. (Please, bear in mind this is an expression, and I'm using it as such, not to offend anyone).

The temperature regulator power of water lies in its latent heat property, which, for water, is one of the highest there is for evaporation.

Honestly, I do not know how many times this has to be repeated, and this alone would put all this "global warming by CO2" nonsense off: the irradiative heat from "thermal (infrared) affected molecules" (I believe the term "greenhouse gases", apart from conceptually wrong, nowadays is misleading) cannot cause extra heating of the system. That would mean "doubling" the solar energy, thus suggesting "creation of energy", therefore implying in something like "infinite energy on a loop". It is like plugging those electric extension powers in itself, or saying that all energy necessary for anything is a candle. It is to say one can melt an iron structure with a candle. Besides, energy always flows from a warmer object towards a colder object.

It is that supply of water (almost 3/4 of the planet's surface) that allows for optimal life conditions on this planet. And it is water that "regulates" weather, almost like a thermostat.

The reflection/absorption argument is also lame. There ain't much solar power arriving at the poles anyway for its reflection/absorption to be of significance. Besides, it is only the visible light that is reflected.

When snow melts, it is because it is getting hotter anyway (winter to spring to summer). However, when snow is falling it actually gets warmer because of the release of energy in the process. It is water that is absorbing and holding most of the heating the Sun throws at us, thankfully. Without all that water and the atmosphere as well we would be frozen at -387ºF at night.

For those still insisting about the power of CO2, I invite them to spend a night in a dry desert. There ain't enough CO2 in the galaxy to make you warm, but be my guest.
I had a hard time getting the point of this article at the end about why he shouldn't have written the original story. Anyone have an insight or some other way to get that point across?

All I can imagine is the guy who didn't want the story told was upset because it reminded him his wife was longing for that other guy but otherwise it's really hard (as a dumb american) for me to understand why that story would bug anyone. And it's certainly hard for me to understand why the author would get banned by the island rather than just hated by the guy who brought up his wife's innocent history.

I loved the article. Well written and certainly compelling to read and fascinating all the way through. I'm just wondering what I missed or some other way to see it and truly grok it.
The really fascinating thing is that the distinction between ¬¬x and x actually parallels the distinction between proof by contradiction and normal proofs. That is, if you have any classical proof of x, you have a constructive proof of ¬¬x.

The way I like to think of it is that, in constructive logic, both x and ¬¬x represent evidence for x—it's just that ¬¬x is weaker. You can still derive all the results you want, you simply have to be more explicit about whether you have constructive evidence or not.

I think you need to split the unsoundness bug, which happens because thread::scoped uses unsafe code, from the "you can write mem::forget in safe code" bug, which is arguably not a bug but is at least an enormous footgun waiting to happen.

When the footgun goes off in unsafe code in the standard library, you get use-after-free and memory unsoundness. When the footgun goes off in safe code written by mere humans, you leak arbitrary resources.
If Toyota had anything to do with that analysis then it wasn't independent.

Given that there are countries (eastern europe) where there are hardly seen, I doubt.

Profit is not only sold Apps. The companies selling handsets also might be quite happy with Android's share.

E-commerce platforms always require highest level of encryption & security as they are dealing with financial transactions. EV is the only SSL Certificate which gives highest security to online transactions.

Comparing with Symantec, Digicert is not so popular in SSL industry. Symantec is a giant in web security industry and world's top most website are using Symantec Security solutions.

Symantec's Secure site pro EV SSL comes up with SAN feature which lets you secure multiple domains with single certificate, Digicert EV SSL doesn't have this feature.

Symantec's Secure site pro EV SSL has built in "Daily Vulnerability Scanner" which scan website against malicious threats and reports immediately whereas Digicert EV SSL doesn't have this feature.

Rather than buying directly from Symantec, if you choose re-sellers of Symantec such as "CheapSSLSecurity.com" you will get maximum discount.

At CheapSSLSecurity.com you can get Symantec Secure Site Pro with EV SSL certificate at only $839.00/year.

As your business is E-Commerce, EV SSL must required. If price matters for you then you can go with Comodo's EV SSL certificate. Comodo became leading SSL certificate provider all over the world.

At cheapsslsecurity.com you can get Comodo EV SSL Certificate at only $113.00/year.
Hand-over-fist profits? Only at the very top of the market. If you're producer of one of the top 50 or so films, yes people are shoving money at you. In the top 100, you probably broke even and people will be shoving money at you when it hits the home video market. In the top 101-200 films, You'll most likely make your money back and enjoy a modest profit.

Outside of the top 200 films? Then your box office takings were certainly under $1 million (except for about 10 films), and more to the point most people haven't heard of your film. Have a look at yearly box office #s on a site like boxofficemojo, and look at some of the other 6-800 films that get a US theatrical release each year. Many good films have box office numbers that are measured in thousands, and remember that box office numbers are gross - as a rule of thumb, only 1/3 of the box office goes back to the distributor, the rest stays in the theater.

What you seem to be overlooking here is that while some films do indeed make money hand over fist, for the many more than don't, piracy is just as big a problem - not because so many people are pirating an obscure or somewhat unpopular film who would otherwise have paid for it (although this is a problem for quite a few films, eg Terry Gilliam's last film had dreadful box office because they didn't have much money to advertise, but was very popular on file-sharing sites), but because piracy makes it increasingly difficult to come up with any kind of meaningful estimate about a film's long-term earning potential. that in turn makes it much harder to raise financing for a film. It's definitely tougher than it was 10 years ago when I got into the business.

At least in academic circles, statisticians working in forensic inference and statistics widely support probabilistic approaches, to give the strength of the evidence in terms of likelihood ratios (or Bayes factors) with respect to prosecution and defense hypothesis. For example, what is the probability of observing the features of a given trace had it come from the suspect versus had it come from another individual in the relevant population.

The concept of "matching" is also slightly more complicated in reality. Basically you have to account for uncertainty in measurements and other factors. For example, often you won't get a perfect print from a crime scene but a smudged partial mark, which you then compare to an inked fingerprint.
Studies about the validity and reliability of fingermark-to-fingerprint comparison that are based on fingerprint databases of inked fingerprints most likely overstate the accuracy of the method as compared to testing under conditions of real casework.

For some additional background on problems with fingerprints in forensics see:

How are you architecting things that an upstream error will cause your server to die?

Look, in both cases, the request needs to be synchronous. You need to tell the customer that their purchase went through. If you're going to add a whole other bus into the thing and make it asynchronous and have an elaborate polling solution on the client, that's fine, but I would (and do) just have them wait the two extra seconds and either say "your card has been charged" or handle the rare case with "there has been an upstream error, please don't close this window while we retry the request".
