The current technology is perhaps impractical, but it will get better with time. Some advantages of having a building built by a machine are a) the skills of your workers are no longer a constraint on building geometry and b) machines don't care if the houses are all the same or all different, so individual customization is cheaper.

What follows from b) is that it would be less difficult/expensive to customize a house to match the constrains of its site, which is currently hard when dealing with non-flat, non-rectangular lots. One could even generate building designs algorithmically according to some heuristics.

My prediction is that if house-building robots take off, we'll see a lot of co-evolution between the machines and architectural design software.

I would be sold if Dyalog had a graphical environment equivalent to J's jqt, something you can at least plot the data. Everything I can find with Dyalog is .Net and Windows. RIDE seems to be the right step forward, but still much inferior than jhs.

On the other hand, Dyalog can't beat J's open source, but I guess that's something much more difficult to change.
What the death of the CRT display technology means for classic arcade machines
This is why we don't start people out on chainsaws or table saws but with simple hand operated saws.

But cutting down a tree with a hand operated saw (even if it can be done, see the time of logging before chainsaws) is a painful operation, and making very straight cuts without the aid of a table saw and a guide is similar.

APL is a powertool, basic is a hand-tool.

No, this is for a general introduction to the mathematics of computer science. This looks like a basic (and good!) text any MIT freshman should be able to master. Perhaps it's for what 6.001 has morphed into?

If you understand this stuff, you really need linear algebra for today's "deep learning", which perhaps is 18.03 (I can no longer remember).

Sickle cell anemia patient 'cured' by gene therapy, doctors say

This is absolutely a fundamental reason: higher educational system. Atlanta (maybe Texas) is the South's version of SV and it has Georgia Tech, Emory, and others. If a municipality wants to be a top tech city, it needs the colleges and universities to support that.
The data still has to get out though. If LibreOffice doesn't have network access then that can't happen, at least not without an attack on some other systems as well. This protects against generic sort of "drive-by" attacks but if someone is being targeted then yeah, sandboxing the office suite isn't enough.
"The "dutch reach" (opening the door with your other hand which automatically makes you look over your shoulder) is unfortunately not commonly taught in driving schools."

Excellent idea, going to use that one.
Oh, so that's why they do it that way!
I definitely understand that centralized bureaucracy and decision making can be very harmful. I also know that the lack of centralized bureaucracy and decision making can also be very harmful, for example by killing tens of thousands of people with trans fats (or air pollution, or communicable diseases, etc.) We are playing an unavoidable game for very high stakes, where inaction can be as lethal as action.

The typical cycle is that something obviously bad happens to an identifiable victim that can be traced to lack of regulation, then congress and/or the courts force regulation, and then the regulation causes a lot of invisible harm that may or may not be greater than the harm it prevents. My job is to try to make these inevitable regulations do more good than harm.

There would have been a public notice and comment period before the rule went final. But industry often fails to notice things, and quite often, when industry asks for standards to be lowered, consumer groups reflexively insist that they remain as proposed. The outcome ends up being based mainly on politics, which is why getting the proposal right matters.
Every discipline has its cliques.

And I meant "an example" in the sense that justifying a thought on the basis that "most people think" is an example of groupthink.

If it's such a problem, how come there hasn't been a single case of a in-flight structural failure from corrosion of any strut-braced Cessna? In fact there have only been two cases of structural failure in 172s, both of which appear to have been caused by trying to do aerobatics:

Status seeking, being inherently zero-sum, is a pursuit that will only leave you unfulfilled in the end. In fact, I think the very fabric of human existence is predicated on this inequality that status emphasizes.

As for myself, I try to fight against it by refusing to share information that's not contextually relevant. It kind of sucks sometimes, but I think it's the "status-free" way to do something. Living in MA, I always manage to be amazed as some Ivy-League graduates slip the fact that they attended an Ivy League school into a conversation that has nothing to do with their education or pedigree.

Part of the MO for TPP was to have America's trading partners conform to better environmental/safety/health regs, but any chance of that happening now is a pipe dream, let alone with either China or India.

Two Ways of Implementing Convolutional Layer
Currently Dyalog APL provides green-threaded concurrent programming using a traditional "fork" model as well as a CSP-style distributed computing model called "Isolates." In addition, Dyalog will utilize vectorized operations on the CPU for a number of primitives and code patterns. Co-dfns provides for additional functionality by providing vector level parallelism on the GPU/CPU and a true threading "fork" (this feature is only part of the language extension, and has not yet been implemented). So, if you write your code in a Co-dfns compatible manner (closed single Namespace of dfns, and some limitations in the current version which are being lifted rapidly), then you will be able to execute it on the GPU, CPU, and SMP machines.

As a trivial example, say you wanted to compute the quadratic prime numbers algorithm in parallel:

Primes←{(2=+⌿0=X∘.|X)/X←⍳⍵}

You would simply compile this function inside of a namespace using Co-dfns and you could then run this function on the GPU to improve performance. The compiled code would run on either the CPU, GPU, or SMP machines.
Thanks urs2102, that was some really good suggestion, I knew I had to do these but now I got better picture of what needs to be done.
I think this would happen if L1 was a stable lagrange point, like L4 and L5. That's not the case though, L1, L2 and L3 are unstable. To put it differently, ignoring the centrifugal force, at L1 the gravitational pull of Mars is equal to the gravitational pull of the Sun; when you move the sail towards Mars, the pull towards Mars increases, the one towards the Sun decreases, and the resultant points in the same direction as the pressure on the sail (i.e. towards Mars). Nothing is balanced, in the end the sail falls towards Mars.
Well, now you are trying to increase your status as someone who doesn't care about status. The fact that you felt it worthwhile to delete your bio, just to prove to some random internet stranger that you don't care about status, clearly shows that you care.

It is ok to care about how others perceive you. We are social creatures, and we care about what others think. That isn't a bad thing.
There may be published studies, but I haven't looked. But consider the Beats. Most of them were trust-fund kids. Or the people who hung around Warhole. Or the early college hippies, protected against arrest by institutional influence. Or what they used to call the jet set.

Drug use is common among wealthy kids because they're so well protected from consequences. All children like to experiment, and have fun. So why not?

I knew a guy who burned through his inheritance, and then became a heroin smuggler. He used his friends as unwitting drug mules, and kept living the high life on the profits. But then one of them got busted, and sold him out. Oops.
There are many ways to ensure a system is fault-tolerant, scalable and still reasonably safe.

They certainly have the resources to solve this if only they want.

Did you read the article? The whole point was that status is NOT inherently zero sum, since everyone uses different criteria to determine their own status.

I'm sure you know that Microsoft Surface laptops all have magnetic power connectors.
Good point, and it's because of the status quo bias. When an alternative is proposed, people look at what they lose, and since we don't like loss, we say, "No, I don't want that".

Thought experiment: say Macs had USB-C for 10 years, and the latest Macbooks switched to MagSafe. There'd be a lot of complaints about Apple locking us in to their walled garden, and how we have to buy a proprietary overpriced charger now, which can't charge other devices, moreover.

One technique I try to follow is an anti-knee-jerk reaction: if everyone has a knee-jerk reaction about something, I remind myself of the advantages of the alternative.

Ultimately, the only true test is time. Wait 2 years and let the emotions cool, and you'll know if the outcry was justified.
Point taken. Less so than before, but it's still fairly weird in many areas. LA and the Bay both have odd sub-cultures and not-so-far out of the city you get some fairly hippy types, but it depends on a lot.

Palo Alto I don't think has ever been quirky.

If a movie reviews poorly but does well at a box office. Were the critics/reviewers necessarily wrong? You think people who gave Batman v Superman a bad review thought it still wouldn't be a huge box office draw?

I doubt anyone who wrote those blog posts or comments on HN believes that this product would cause Apple to go belly up. Apple is literally one of the biggest companies in the world by any measure. Having a mediocre product is not going to tank Apple immediately. Being more and more complacent on their part will cause that.

To see Apple's future just look at what happened to Microsoft in the early 2000s. They got complacent, but they still had that sweet, sweet, Office money right?!

Not liking the latest Apple product, and then showing their stock price as proof those people are "disconnected from reality" seems a bit of an overreach...

This class is 6.042 and is not required for CS majors. 6.001 morphed into 6.01, which is something to do with python.

18.06 is linear algebra. 18.03 is differential equations, which you don't really need for machine learning.
Why now? Perhaps because millennials are getting older? Next to the boomers, they represent Canada's largest generation, and within the last 5 years started to reach the age where one normally starts to gain meaningful savings and starts to settle down to raise a family. They are also more likely than previous generations to want to live in the downtown of major cities. They also reached this stage of life as we dropped interest rates to practically zero, enabling them to afford much more than anyone before them. What was being served by dorm rooms (if you recall, the postsecondary schools had to go build-crazy in the early 2000s to accommodate these same people) and bachelor apartments rentals now wants to own multi-occupant homes – preferably of the detached type – without having to leave the area they established themselves in during early adulthood.

I don't think foreign money can ever explain "why now". Even if we agree that there is foreign money being invested, there still has to be some underlying driver to make them stand up and take interest in that investment opportunity. We can assert that it is not simply foreign money wanting to own a piece of Canada, as many parts of the country are only keeping up with inflation, and sometimes not even that. I think there had to be some change in the makeup of, most notably, Toronto and Vancouver that made it appealing now, and I suggest it is down to these demographic shifts.
I don't know... I don't think some guy who runs off and lives in the woods on their own is involved in the status game (it takes at least one other person for status to be a thing).

But yes, if you are involved in society, then you can't avoid status entirely.
Yup. I disagree with it, obviously. I don't think the author gives sufficient evidence to prove that it's not zero sum. Can everyone be of high status? The answer is obviously no. Like I mentioned before, the very idea of status to begin with is relative. If status is not zero sum, that means that everyone can be of "high status". I believe such a thing is nonsensical, and so, impossible.

All you need for introductory machine learning is multivariable calculus (for some simple optimization stuff), linear algebra, and probability. If you don't know probability, here's a good course: https://ocw.mit.edu/courses/electrical-engineering-and-compu....

Thanks, that is a nice write up. I especially like "Imagine a world where the way desktops are meant to function is by plugging your ultraportable into any available set of peripherals: monitor, keyboard and mouse. The interchangeablity and convenience of that, necessarily implies that the brand and type of monitor / keyboard / mouse you plug your ultraportable into doesn’t matter, as long as they’re technically compatible." I have written on the same topic, and that is the future I see. Microsoft had the right idea with Continuam, and I expect Apple, Microsoft, and Google to all try to make this work on the mobile side while leaving it to 3rd party manufacturers to develop USB-C compatible monitors that act as a hub for keyboard, mouse, USB drives, etc.
I try to avoid going bare metal as much as I can because of the difficulty involved with working with GPUs at that layer. I try to focus on higher level concerns, and use the excellent low level work of people such as the ArrayFire developers to handle the low level stuff. I still have to understand it and work with it at some level sometimes, but for the most part I stick to my core abstractions.
I was under the impression from reporting on the sting that Playpen was an onion site, not a clearnet site. If that's the case, traffic wouldn't be going through an exit node to get there, right?
> but in technology people spend a lot less time worrying about that

That has not been my experience. I'd say people in technology are just as political and status obsessed as anyone else. I think people in general don't want equality as much as they want dominance. They want to have it better than the other guy and high status helps achieve that.
I'm not sure how much we know, but it could easily lead to massive disruption of our technology if nothing else. We might not be wiped out, but we could be in for a lot of pain depending on how things go.
Which doesn't mean that they should chase those customers. If they're not generating significant profit, it doesn't matter much whether they stay or leave.

When irrigation water is put directly on produce that will soon be consumed raw, it will transmit pathogens and should be drinking-water standard. This was not disputed, and was in the final rule.

However, if the water will go through manure before being absorbed by the the plant's roots, it is very wasteful to first purify it to drinking-water standard. Drinking-quality water is not everywhere in the quantities needed for irrigation, it requires expensive filtration and processing. Everyone saw the logic of this when it was pointed out, nobody was 'stumped'.
Even if you replace one definition of status with many (seven billion?), each one of these new definitions is itself zero sum.
Clarity got it, thanks hasitseth
Just like Chinese and English are different so APL and for instance C, ruby or Basic are different.

By defining symbols for operations more complex than just the basics APL has a learning curve but once you have gotten past that it is actually more readable than the alternative because you have less to hold in your head that does not actually help to solve the problem.

All that syntactical sugar and symbol stuff requires some expenditure of cycles and the cognitive load spent on that won't be available to solve the problem at hand.

That's where your definition of 'readable' is different from what the APL people consider 'readable'. They are talking about reading the problem, you are talking about being able to 'parse' the code into (re)representing the problem.

In APL the code is what it does. In most other languages you first have to figure out what it is before you can figure out what it does.

In essence difference between the word 'cat' and a picture of a cat or an ideogram representing 'cat' (assuming one exists), or even an actual cat.

I think it more assumes that the police's incentive is to maximize the ratio of accusation to conviction as much as possible, which is a reasonable goal.

If they were simply trying to maximize the total number of convictions, then this wouldn't necessarily help; the police would just make broaden the kind of cases they'd accuse

And ofc, it's the function of the police to maximize the misdemeanor to conviction ratio; it's the function of the court to judge the quality of misdemeanor.

It is the function of whatever social/moral arm of the government to minimize misdemeanors. A police officer minimizing the number of accusations should only be doing so for practical reasons; In the ideal world he shouldn't be trying to interpret the law itself, and if it should exist (because it should in general be explicit what is and is not legal, and in general, it is not the policeman's job to decide what is moral, it is to enforce the standing morals.)

But its not an ideal world, and nobody wants to spend time/effort/money on a trash case, so the general incentive is to successfully convict; not to simply try.
> competing on platform, not price

I believe it'd be more appropriate for Linode to say that, which has long had good reputation in terms of the variety of regions, the quality of network, etc., and which used to be on the more expensive end. DO, on the other hand, actually debuted with the low prices, if anyone remembers.
Unlikely. First, we know what they paid for the hack, and secondly, the iphone involved was an old model without a secure enclave - multiple researchers suggested different attacks.
> 5) Open versus closed source is a red herring. Everyone is using pre-compiled binaries.

With a very salutary trend toward reproducible builds, which will help prove a connection between the source and binaries. (Though it's taking years to get there.)
TL;DR: An internet explains in detail how one can use git-filter-branch to give some files in an existing Git repository their own repositories while preserving history. It seems important that “git filter-branch” is not “git rebase”:

To be fair, Austin does have a substantial semi-conductor presence. But we're still an order of magnitude behind SV levels of funding. Need one or two Googles for that.
I too switched to Windows 10 from OSX about a year a go. Yet, in my humble opinion Apple still makes the best laptop hardware - all other things equal their trackpads remain unmatched. Thus I remain to be an avid MBP user where I first used bootcamp to boot to Windows. And few months back I went a step further and eradicated OSX partition altogether and now my shiny MBP only has Windows 10 partition left.

You'll need to get at least a free copy of Dyalog to use the compiler. They have a number of different free options. If you intend to use the compiler, it is available for use by all under an AGPL license. However, the generated code also uses Co-dfns code and is likewise under an AGPL license. If that license is unsuitable for you, then you'll need to arrange for an alternative license through Dyalog. Normally this will only be required for people interested in using Co-dfns commercially in their closed source projects.

The Co-dfns work is run like an Open Company however. You are welcome to submit contributions (see the README for more information) as pull requests and can onboard yourself at your leisure. I'm working to encourage more people to support the funding of Open Work on Co-dfns, but that's a long, slow process.

So, yes, generally speaking the compiler is designed to be used in conjunction with the host of additional tool support you get from Dyalog APL (the interpreter). However, Dyalog makes it as easy as possible to get a copy of the interpreter.
