>I don't see why we should not describe models in terms of continuous variables.

You're being way too polite in your wording, as your next paragraph states, every field that uses computers has done it since the computers were invented. Allow me to push it further: AFAIC almost all hand calculated math is discrete. The numbers you can write on a page are countable, in fact finite, so all actually calculated math is "discrete" in some sense. No one every really touches the full continuum of R other than abstractly: real calculations whenever you truncate pi or sqrt(2), or generally calculate with a fixed set of digits, you are doing _discrete_math_. So yes, Q is dense in R which helps, and you could write out more digits if you really wanted to, but even then, people restrict themselves to small, finite subsets of Q and even resorting to using things like logarithms/order of magnitude to keep that set as small as possible since our brains can't take all the hairiness. But still, that set is large enough to still do the things we care about anyway.

However, when people want to think abstractly rather than explicitly (calculating), it's easier to take the limit as the gaps go to zero and deal with clean, C^\infty functions. I mean, that's literally what people mean (at least how my experimental physicist brain thinks it does) when they say analysis/calculus is about approximations. I deal with plasma in the hot, nonquantum limit so my ions and electrons are in fact discrete particles. Whenever I calculate an electric field or a magnetic field for the distribution, I ignore the fact that there will be noise on the scale of individual particles and replace that noisy function with a clean smooth function, which tends to be a good approximation. In fact, this is how almost every classical physics problem is solved, you ignore the structure on the particle level and pretend it is "continuous". Same with materials engineering, and so on.

I think there's a trust problem with that. How do you arrange the transaction? If I offer to sell you a zero-day for X BTC or something, how do you know that my zero-day is real and exploitable, and that I will actually give it to you and nobody else? How do I know you will actually send me the BTC? How do I demo it in a way that at least proves that it works without giving away enough info to recreate it?

I guess Zerodium has enough reputation that you can be reasonably sure they'll fork over the cash after you show them your bug. Building that kind of reputation on the darknet with cryptocurrency isn't going to be easy. If there was anyone like that out there, we'd already know about them.
One thing I don't see mentioned here is weight. Statistically people have gotten a lot heavier, and I wonder if being significantly overweight does not increase the risk either?

A. It’s very easy to go over budget building a house, and therefore a riskier proposition for low-income people

B. It can be much harder (higher down payment/harder to qualify) to get a land loan and a construction loan, Vs. a mortgage + more expensive as you need to pay for all of that for the time the house is being constructed and also pay for a place to live...

C. Often times lot values imply the highest density development e.g. in order for the purchase price of a lot to make sense you can’t just build a single family home but need to build 3 town homes for the economics to workout

cp most certainly does copy directory structures. Just not filtered ones whereby just certain entries are arbitrarily selected from the source tree and only those are replicated in the destination tree.

The issue in the question is that the person has expanded, into the cp command line, a bunch of full paths, effectively like "cp a/b/c/file1 a/b/d/file2 .... dest" and wants those relative paths to be re-created under dest as dest/a/b/c/file1 and so on. Indeed, cp does not do that; it simply puts the specified objects file1 file2 ... into dest.

An option to create each object's relative path under dest would be useful, but it would be a pretty awful default behavior.

GNU cp has this option:

`--parents'
Form the name of each destination file by appending to the target
directory a slash and the specified name of the source file. The
last argument given to `cp' must be the name of an existing
directory. For example, the command:

cp --parents a/b/c existing_dir

copies the file `a/b/c' to `existing_dir/a/b/c', creating any
missing intermediate directories.

GNU Coreutils is in active development, unlike the Windows command line which is basically abandonware (as, to be even-handed, is the Unix (tm) command line.)

Very much so. I've seen sporadic news-reports of people suffocating their babies, by rolling over on top of them.

The mirror claims 133/year, in this piece, but I'd imagine true stats are harder to find:

https://www.mirror.co.uk/news/uk-news/133-babies-accidentall...
> 350 deaths per year to about 200 deaths per year

It's correct but their numbers are presented in a confusing manner. The UK figure is total deaths for the whole country, but the US figure is given per 100,000. There were 774,835 live births in the UK in 2016. So that's 350/774835*100000 = 45 per 100,000 vs. 90 per 100,000 in the US. So 50% lower.

> There is a LOT of room in the country for growth

No there isn't. All the places with viable logistics and water supply are pretty much full up. Urban areas need barge transport, good rail grades, aqueducts, and rivers to carry away waste. You can't plop a city down in the middle of nowhere. The energy economics mean it will never work. All the sites worth building on have been built on. A lot of the places supplied mostly by truck are of questionable viability in coming years.

Probably the only area of the country that could long term sustain a much higher population density is the great lakes region.

This thread is an excellent example of how people will over-interpret such a warning.
No but thanks for putting words in my mouth. They were dumb because they clearly didn’t even bother to do basic due diligence. The fact that there were no other marquee VCs in on a $10b valuation should have raised some flags. It did not. And they weren’t taking a $100k punt. These were investments of tens of millions of dollars so you think that there would have been some basic technical due diligence. This is what I call dumb money.

When a VC sees a huge valuation and the only other investors on the captable beyond the Seed/A rounds are celebrities, pension funds, SWFs, family offices and hedge funds they say: “we’re worried that this is the next theranos”
Thank you so much for pointing this out. We'll get updated numbers out soon. How did you benchmark plaid, out of curiosity? The error which I correct here (https://github.com/brianretford/nnvm-rocm/blob/master/mxnet_...) was caused by a desire to roughly approximate how keras does things, and plaidbench w/ keras is the easiest way for us to evaluate things, though it definitely adds in a lot of overhead. My script roughly matches the numbers I get out of your script, though I will say that I think the TVM time_evaluator should be calling Sync on the inside of its loop, to be fair (which I patched it to do to compare against your methodology). It doesn't make a huge difference, but it does exist.

If I just pull the overall kernel runtime from our logs, I get ~525 inferences/sec.
What are the technical obstacles to growing artificial organs outside the body, perhaps from the patient's own cells so rejection isn't an issue?

Are artificial organs effectively impossible due to some law of biology or design of the human body? Is it so far-fetched that nobody's funding it? Or if it's being worked on, what's the time-frame -- will we see this in 100 years, 30 years, 10 years or 3 years?
I had a 15.5 mm herniation and had to get surgery, my sciatic nerve was pinched to the point I had numb feeling in my left leg. I'm two years removed from surgery I'd say I'm 97% squared up but at times I can still feel it.

Please get an MRI if it's less than 8 mm, you should be able to avoid surgery, but see a specialist (neurologist specializing with back). Ice it don't heat be careful lifting heavy weights or deadlifting (thats what caused mine). Good luck

"most Linux distros" might have been wrong, but on Debian and Ubuntu at least, the executable /usr/bin/ssh-agent has group ssh and has the sgid bit set. So, when you run it, it automatically runs as group ssh via file permissions, denying you the ability to debug it, precisely because you're not a member of group ssh.

"being setgid to group ssh" and "calling the setgid system call to become group ssh" are two pretty different things, and it's unfortunate that UNIX uses the same terminology "setgid" to describe these two. (They don't even have the same end result; the system call changes the real group ID, and the permission bit changes the effective group ID.)

I don't think ptracing yourself is even possible (also how would you restart the process once stopped?):

$ cat src/main.rs
extern crate nix;
use nix::unistd::*;
use nix::sys::ptrace;

fn main() {
ptrace::attach(getpid()).unwrap();
}
$ cargo run
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Sys(EPERM)', libcore/result.rs:945:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

Starting it under a debugger means that you have to re-load the encrypted file from disk and re-enter the password. The attack we're worried about seems to be that the system is secure when the key is initially loaded, but at some later point some malware tries to steal the key. If you have access to the password, you can just copy the key and decrypt it on some other machine.

It sounds like the key fob did work as others pointed out. However I'm sure there are still lots of unfinished things. When I was out in Chicago with my buddy late last year I got to drive the updated Model S and I noticed the windshield wipers wouldn't come on automatically whenever it rained. After digging through the menu we found a thing that said said something like "feature coming soon" for automatic wipers. Kinda sucks to not have feature a lot of very entry level luxury-ish cars have. Overall the tech is cool and I bet they offer a lot more future functionality through patching. Just feels like they are always in a rush to launch to get some cash in the door and they go with "that will do for now" as the solution.

I hear they got a patch out around last new years to finally address this.

What’s the source of these numbers?
Modern war doesn't work that way. In fact, today, 'war' doesn't actually work at all.

What China wants is for it's hegemony to be recognized.

Why invade Japan and risk it being highly unpopular at home; being sanctioned by every major developed economy; militarization of it's neighbourhood, etc. etc. (on top of actually being unable to actually conquer Japan)

Within 20 years, it could be well within the position of dictating Japan's foreign, or even some domestic, polices to such a degree to have it essentially as a vassal state. Japan perhaps willingly chooses to make certain concessions in return for favourable treatment for China - say if the two countries considered closer trade relations at one point.

There's also diplomatic & soft power. An aging Japan turning to immigration which de facto will largely result in an influx of Chinese (already the largest foreign minority in Japan). These chinese immigrants over time have more power within Japanese policy.

If China manages to launch it's own cultural industries to the degree of S. Korea's or Japan's, that would make room for more Chinese influence.

But in the end it works both ways. Young Chinese imitate certain aspects of Japanese culture as well. It doesn't really need to end in war or even aggression for both countries to slowly learn to have a meaningful relationship with each other.
An approach I did sometime back was to create a generic template kind of an app (in code not published) for B2B that had integrations with ERPs where the bones were finished but the UI was pretty bare so it could be customized for each client and be deployed as its own app each time. I had built up this toolkit overtime and it got more profitable and easy as I went. I could easily tailor it to clients so it was very branded and unique but yet the bugs and time to complete was very low in the finished product. I still get paid for this monthly even though I'm doing a startup and have moved on. It still pays the bills. Everyone's experience is different. I had an advantage of niche ERP integrations that pretty much no one else did and could sell it way lower than the competition. This is just a hindsight thing and people tend to fool themselves that their decisions were correct but in reality I got lucky in my approach and got lucky I had flow of people that gave me referrals. Find a pattern that works for you but gives you some clear advantage.

I claim it’s extreme and unreasonable because it’s outside of the view most people have on the issue. Most people do not see unions co-opting the normal political process. Most people don’t think being a public employee ought to mean giving up rights. The exceptions I mentioned are exceptions in current law, not necessarily exceptions that I support. The law has inconsistencies in it. In the comments one lawyer mentioned that the government can’t censor and this is of course not true. CIA employees have limits on their free speech rights for instance.
I taught years 3 - 6 kids scratch for about 3 months. While I wouldn't say that Scratch taught them how to code, what it did do was teach them two things: thinking like a coder, and to be excited about coding.

Critical thinking and problem solving is something that seems like it's slowly fading away in modern education. So much of it is pure memorization for fill-in-the-bubble style tests. Letting kids at an early age tackle a problem that requires them to use separate steps and pieces of logic to complete seemed very developmental to me. Even over that short time span I noticed a huge difference in the mentality of how the kids approached problems after the course was finished.

As far as being excited about coding, I can't say just how important this is. Especially at a young age, as long as they feel like they have the capability to use the tools, almost 95% of the students I taught were fully engaged in playing with Scratch. I've taught adults js for a while now, and I usually get about a 30% engagement in any course, so those numbers were crazy to me. The problem though is when they get stuck, it has to be intuitive enough for them to figure out how to solve without being able to pour through stackoverflow posts. Kids don't use SO, they use Youtube to figure things out. Youtube had great scratch tutorials for them to follow, and so it was easy for them to get past things in a way they were comfortable with.

Overall while I think it isn't something that should be invested in heavily by kids, it's a great lauchpad to get them excited for coding in general. I see it as something akin to lego - it's there to fuel creativity and interest, not necessarily to replace architecture or engineering.

There are a couple of problems with the obsession for flat cornering.

One is that its uncomfortable for people in the car, particularly passenger, who are pushed sideways into the seat-bolsters and side panels.

More importantly is when lateral grip finally breaks there is no warning to the driver with a cocked wheel and gentle progression: it just lets go.

This is great! I try to keep track of such lists, and this is the best I've seen so far.

I put up a Mediawiki instance five years ago (wikilogic.org) to publish my own list, but didn't follow through. Interestingly I put a FS link in the bottom right : )

A couple of tweaks I would make:

- Putting 'Inversion' at the top--I think it #1 in terms of underuse.

- Aside from Occam, Bayes, Pareto, Dunbar, and Pavlov, I would drop all models named after people. The chances of someone remembering something are much better if they don't need to learn a name in conjunction! (e.g. see the other comment about the difficulty of learning "Hanlon's Razor")

To take this material to the next level, I imagine the next step is to build case studies.
