For more than a decade, the Semicon industry has been trying to extend Moore's Law with CO2 laser technology that essentially has not had a generational advance since Moore's article was published. The laser wasn't the only issue, but now that those other barriers are being overcome, it will be the prime one. Far from acceptable cost-of-ownership, and inability to scale, have been known laser limiting factors from the beginning. That makes the hesitancy of companies, such as Intel, ASML/Cymer and Trumpf, to invest in CO2 laser breakthroughs that have been presented to them, more than shocking.
The minimum commercial viability of 250W EUV@IF (Intermediate Focus) has still not been achieved. There is no chance of them scaling to the 1kW EUV@IF that Intel has stated is needed for truly sustainable viability.

There's a page somewhere on the nftables wiki that shows all the operations you can do, but you essentially can bitmask and compare, or just compare and do something based on the result of that conditional, so I guess exactly what you want.
The standard select and poll syscalls perform just fine if you only have a handful of sockets. Heck, they perform just fine as long as a nontrivial proportion of your sockets are ready at any given time.

The place you need kqueue and epoll is when most of your connections are idle -- IRC servers and web servers with large keepalive times. But the vast majority of processes are not IRC or web servers.
And I'm grateful for that. :)

1.1 Who Should Read This Book?

This book can be useful for a variety of readers, but we wrote it with two main target audiences in mind. One of these target audiences is university students(undergraduate or graduate) learning about machine learning, including those who are beginning a career in deep learning and artiﬁcial intelligence research. The other target audience is software engineers who do not have a machine learning or statistics background, but want to rapidly acquire one and begin using deep learning in their product or platform.
Currently in California looking to get out. It's too expensive, too crowded. The state of California is beautiful but laws and people ruined the whole thing. I feel like we don't have enough privacy here, we live on top of each other even outside of the main cities.

If you're coming from Toronto I think the weather is not your main concern... So definitely avoid California. You'll get a higher paid job and will spend the extra money into taxes, housing, etc. So it's all fake here people don't save more money (we're all cash poor in Cali).

Texas is the best alternative to California in my opinion. It's warm(er), you get more space and privacy for less, people are actually nicer (especially around the Austin area) and the food is amazing. I've always thought Texas was the craziest place on earth but after visiting a couple of times I totally see myself staying over there for a few years.
You are incorrect. The tech companiew here, even the small ones have best in class insurance coverage. Most companies cost anywhere from 1000 to 4000 per year for only the primary employee, many others add much more on for dependants.

If I could work 100% remote? Back home in northwest Maine. It's beautiful, it's cheap, I know everyone, my family is all there, there's a ton of stuff to do outside, it'd be a great place to raise children. It's home, and always will be.

The Mac's entire brand identity can be summarized in three words: "It Just Works." Any time people see a machine running MacOS where those words are not true, it damages the entire brand.

Thus Apple is happy to forgo the extra revenue they could get by selling MacOS separately, since by doing so they can ensure that the world is not full of crappy beige boxes slapped together by incompetent OEMs sourcing parts from the lowest bidders with the word "Mac" attached to them.
Topics of contention between two nations (or worse, between two political factions inside a nation) are usually suspect. Even if every sentence is meticulously sourced, you can't tell if someone is "lying by omission." Basically, the tone of the article is determined by which country (or faction) can muster more people with free time and passable English skills, which may not correspond to actual expertise on the topic...

I agree that math/physics sections are pretty good. It's difficult for knowledgeable people to disagree on these matters...

>For registering, is it possible to use a disposable number?

Yes, I use a Google Voice number for signal. It's theoretically possible to use something like a payphone or a free inbound number from callcentric, so long as you can receive incoming calls.

It's not required again, though if someone takes over the number they can re-register on Signal. You'll stop receiving messages then, and your contacts will get a warning that your safety numbers changed.

Sure, but that depends on location. $50/h is a really good price for many countries. Obviously, USA is not one of them. ;)
Australia, certainly, just not sure where. Sydney is great but it's way too expensive and I hear dreadful things about the commute. Adelaide is a lovely city but perhaps a bit too dull for a young adult couple.

I've heard good things about Perth and Brisbane but haven't had the chance to visit them yet.

Otherwise I'm happy to stay in upstate New York. It may be cold half the time and gray for even more, but there's also a comfort in having roots in one of the best places in the world to deal with climate change.
Then when grandma comes to visit, she gets a parking ticket because she didn't get the right permit?

No, the better option is for shopping centers to have enough parking for the customers they anticipate having. Maybe giant parking lots suck, but a business shouldn't be able to destroy a residential neighborhood like that.

I've lived in plenty of places where the stores were above the parking garages, and no one from the street could tell there was any parking at all. That's always an option.
I have trouble recommending Texas--even Austin. Personally I pretty much hate the climate for much of the year and it's not an ideal spot for most of the outdoor activities that I favor.

Other than the West Coast, I'd probably advocate for either New England or Colorado.

There's virtually nothing in security that works this way. It's not the NFL. We don't pick teams and root for them. There are things that Google does that are superior to the alternatives, and there are things Apple does that are superior to the alternatives.
Chicken and egg. You can't have one store decide to not have a parking lot, because no one would go there. You could require all stores to be densely packed with no parking lots, but you can't force existing businesses to move or rip out their parking lots, so that would fail too.

Believe it or not, we actually have businesses that are so dense that walking between them not only makes sense, it's the only way to get around. They're called "shopping malls" and everyone hates them.
The math sections are okay up to what a typical mechanical engineer would know. My own sub-field is very poorly covered.
It is interesting that when XHTML was popular most people actually made and served HTML pages (with content type text/html) even if they had a XHTML doctype. That is why this standard was dead from the beginning. Though personally I like the idea of not displaying the page if there is any error in the code.

Indeed. It's astounding how many of the Trump-Russia claims simply fell apart: the supposed lifting of sanctions on selling IT equipment to the FSB that in fact specifically forbade that, the secret communications link with Russia that turned out to be a sub-sub-subcontractor sending marketing emails for Trump hotels, the fake Clinton email that Trump could only have got from Russian outlet Sputnik... or from the Trump supporter on Twitter whose misreading of a real email went viral and lead to that article, the supposed pro-Russian change to Republican foreign policy that left almost all the anti-Russian parts intact but matched up neatly with Trump's long-stated foreign policy views, and so on ad nauseam. Despite this, the endless repetition turned it into something that everyone simply knows is true.

It's worth reading this article by Ron Rosenbaum, author of Explaining Hitler:

https://lareviewofbooks.org/article/normalization-lesson-mun...

He agrees that "to compare Trump’s feckless racism and compulsive lying was inevitably to trivialize Hitler’s crime and the victims of genocide", but also explains in substantial detail how Trump's playbook closely follows Hitler's.
It feels like this is a missed opportunity to use a content-addressable store. It would be super valuable to have the capability of hashing content and knowing when you don't need to re-download it.
I really wish there was a law that forbids using the Homeopathic label on a product that isn't really homeopathic, but just non-medicinal. For example, there are some teas or cough drops that are soothing when you have a bad cold (in a similar way to how lemon or honey helps you feel better). Often these are labeled as homeopathic, even though they contain no homeopathic poisons. I don't mind getting non-medicinal remedies, but when I see the homeopathic label I tend to shy away.

I think boredom is important, and if you aren't experiencing it in some measure on a regular basis then it is possible you're depriving yourself of the ability to experience maximum pleasure from the world around you.

Ok, that was a lot of hedging language. Here is what i mean. I tend to view the mind as a complex but general purpose signals processing device (its been a useful model for how i understand why i do what i do), and I tend to understand that the brain's natural bent is to normalize sensory input. This explains why if you wear colored lenses, the brain will filter out that color and return your perception of what you see to what it considers a normal white balance. The way the brain tends to filter out pain is another example.

Using that understanding, I tend to define boredom as the feeling of desire for stimulation. The reason why I think boredom is important is because if you have been experiencing a lot of stimulation your brain will have normalized those sensations down to a more normal level. That means your ability to derive pleasure (or pain) from an experience is dependent on how much experience you've had lately. When you do something that produces little stimulation, your brain allows itself to lower whats normal.

This is why, I think, meditation and the need to "unplug" are considered so beneficial. Ultimately, what you want in experience is a kind of sin wave, where the length and amplitude of a given experience has been tuned to your specific personality and physiology. Some people like a very mild wave form, some like an intense one, but times where you are able to normalize allow you to re-experience enjoyable activities over and over again without burning out.

---

Having said that, I think that often what people like DFW experience that drives them to suicide isn't boredom perse but boredom combined with depression and/or despair. A struggle with despair is much worse when you go through periods of boredom because boredom makes space for the despair to fully occupy your mind. Experience is distracting, but not a cure.

Anyway... those are my thoughts. And for a bonus, a poem i wrote some years ago encapsulating some of these thoughts.

life is like a sinus rhythm

its ups and downs

beat in, beat out

the problem is the frequency

too fast, too slow

we complain, we exult

but what we really want

is proper length and amplitude

Hmm...it's been core curriculum in my school's CS department since I was there (almost 20 years ago) -- this is the first time I've seen visualizations like this though.

The next evolution will be to make these type of video lectures/visualizations interactive by implementing the math animation engine in JavaScript/ClojureScript and syncing it with the audio.
>And if men enjoy driving, who can stop them ?

The government. The government stops a lot of people from doing a lot of things they enjoy because those things pose a danger to society. That's like 90% of the reason the government exists.

>who is going to fix the broken tires when it happens?

Mechanics. Just like they do today. There's nothing different about the tires on a self-driving car than on any other car.

A weakness in the way these guidelines are worded is that it's not clear enough how much security experts discourage people from using email. Email is the single largest risk most at-risk people have, and not just because only 2 email providers have a team capable of securing their infrastructure or because the protocol is weak, but also because of existing collection capabilities and because of its "archive-by-default" design.

Yes: if you are using email at all, you should use Google's email service. Virtually every concern you'll state about using Google Mail is better articulated as a concern about using email at all (especially because 90% of the people lawyers and activists communicate with also use Google Mail).

If you want, instead, to militate against using email at all, I'll agree and also tell you that I expect this guide will get clearer about that.

Boulder (or Denver) is pretty great if you like hiking, skiing/snowboarding, rock climbing, or just generally being outside.

I currently live in Boulder and with the amount of sitting I do it's nice to be so close to nature. I've gone skiing ~20 times this season and will be transitioning to trail running in the spring.

If the criteria is "for a tech job", then move to San Francisco. The environment here and the learning on offer is unparalleled. And when I say learning I mean good, bad, indifferent, easy, hard, etc.

This is not to say you can't get those elsewhere, but the density here makes it more likely and more intense. A few years at a couple of SF tech companies is a decade of experience elsewhere. The tech companies here are in all different industries, sizes, stacks.

I say that coming from Australia, living full-time in SF - and still openly struggling with the lifestyle here now and then.

If you're trying to balance lifestyle, then I'd follow the other comments here -- Melbourne and Sydney are both terrific cites, great lifestyle and accessible culturally, but still different enough for North Americans to be interesting. The tech scene is still early, but growing rapidly. I haven't spent much time in Austin, but that feels like it may have similar attributes.

I quite like Denver/Boulder and Seattle too, but you might find that's not a huge enough departure from Toronto.

If you like big cities, New York or London might suit. If you're not a fan, then you'll be paying all the big city costs (rent, lifestyle) and getting zero back. London can be particularly tough. London might be worth it if you want a base to explore Europe. Otherwise can be a hard city to live.

Western Europe could be fun too, but the tech scene is much more varied and patchy. If you're looking at, say, Paris or Berlin, then you'd really need a passion for those cities. Plus I'd also suggest you'd want to narrow down to the 2-3 companies that you'd want to work for there -- i.e. the company first, the city second.

I'm with you - QA should be a double check, a fall-back; if you haven't checked, how is that going to be possible? The risk with coders leaning on QA is that they've outsourced their conscience; and the only people really testing and checking the code don't know it very well. Not good.

FWIW, I think dropping QA for periods to shock those who are starting to lean on it is a good idea; but it should still be there most of the time.

The article misses the core issue: neural network architectures are still in flux. "Neuromorphic" chips are hardwired to one architecture, which makes them power efficient but less flexible. When designs are more stable, such chips could be more practical.

Meanwhile, upcoming (non-neuromorphic) AI processors are taking two directions: larger numbers of simplified GPU-type cores (such as NVIDIA Xavier and Intel's Lake Crest/Nervana chips), and FPGAs.

Simplifying cores means lower precision, as fp32 and fp64 are overkill for neural networks and take up lots of silicon. The current NVIDIA Pascal added fp16 and byte operations such as the DP4A convolution instruction[1]. Even smaller precision is practical (down to 1 bit with XNORnet[2], and the DoReFa paper[3] gives an excellent summary of the falloff in accuracy through 32-8-4-2-1 bits for weights, activations, and gradients).

Former WP editor, left because I was tired of abuse after the Esperanza project disbanded.

There is always the distinct possibility that progressivism is part of the correct way to interpret the universe. It seems to pop up in many places.

Consider Pirsig's argument: "The Second Law of Thermodynamics states that all energy systems run down like a clock and never rewind themselves. But life not only 'runs up,' converting low energy sea-water, sunlight and air into high-energy chemicals, it keeps multiplying itself into more and better clocks that keep 'running up' faster and faster. Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organize themselves into a professor of chemistry? What's the motive? If we leave a chemistry professor out on a rock in the sun long enough the forces of nature will convert him into simple compounds of carbon, oxygen, hydrogen and nitrogen, calcium, phosphorus, and small amounts of other minerals. It's a one-way reaction. No matter what kind of chemistry professor we use and no matter what process we use we can't turn these compounds back into a chemistry professor. Chemistry professors are unstable mixtures of predominantly unstable compounds which, in the exclusive presence of the sun's heat, decay irreversibly into simpler organic and inorganic compounds. That's a scientific fact. The question is: Then why does nature reverse this process? What on earth causes the inorganic compounds to go the other way? It isn't the sun's energy. We just saw what the sun's energy did. It has to be something else. What is it?"
