I’ve been using SuperMemo for 15 years, in fact I just finished up my flashcards for today :) It definitely is useful but it isn’t the grand answer to all of life’s problems. It makes it very easy to remember stuff you want to remember but takes some training when it comes to how to structure desirable knowledge as a simple flashcard. Over the years I’ve rubber handed in how much I use SuperMemo, but the happy medium for me seems to be 1. I usually finish my flashcards first thing in the morning, 2. Get in the habit of “thinking with flashcards” by summarizing ideas into single sentences and 3. I keep an ongoing text document in my Notes app on my phone of information I find that is worth remembering. If SuperMemo had a robust mobile app that synced with the Windows program, it would be ideal. Using my Notes app seems to be the easiest alternative that I’ve found.
> This is an example of a transformation that is probably more expensive in compile-time

Why? Reasoning that the value must be 1 after the loop is not even a loop optimization, just a simple consequence of the branching instruction. This leaves the loop but nothing it computes is used anymore so since C++ guarantees that it exits you can simply remove it.

The transformation as a whole might not be useful often, but having a constant for the induction variable after the loop and being able to delete useless loops will both have runtime wins.

> In general, compilers face an iron triangle of optimization: do you want a fast compiler, a small binary, or fast output?

I often wish compilers provided more options to just brute force a bit more performance out of release builds. You can manually tune many parameters but then you need to know a lot more about how the passes work than just saying --compile-for=5h (or something like that, doesn't need to have a hard time limit).

Are you sure about this? I agree this is the case for generic links, but it seems odd for the navigation ones.

Basically every site I could think of (NYT, Yahoo!, BBC, Google/GMail, HuPo, Amazon) has navbars without underline.

Even the site for "Don't Make Me Think!"[0] avoids them.

I can only think of three reasons: incompetence, arrogance or cost. I tend to think it's mostly arrogance in believing the self driving "problem" can be purely done with cameras and software. Cost as well as availability of parts became an issue this year as well.
Ask HN :Why didn't you sign prenup? You regret it now?
I mean most people here otherwise so analytical about almost everything here. Writing code that covers negative cases, edge cases, failure, rare event etc. Why don't then they secure themselves in marriage? It seems counter-intuitive.
Yeah I know "Love is transcends all dimensions ..blah blah". I get it but still hard to understand considering, at least in west marriage fails more often than not and people still don't protect themselves using prenup.

Businesses have no right to exist. If you can't pay the prevailing wage, then you don't belong in business.

I know that sounds harsh but that's the reality that workers live with every day. Can't pay the prevailing rent? You have to sleep in the streets. Can't pay for medical insurance? You get to die from a treatable disease. Why should there be more consideration for businesses than there is for human beings?

New customers too, I was thinking about going to pretty extreme lengths just to use an iphone (I'm not willing to give up on usb-c + headphone jack, but loved the privacy aspect, so was considering a usb-c charging case with a small DAC strapped to the back of it), but with the privacy aspect gone, that seems a bit pointless.

Not complete answers but background: apple’s system works by having your device create a hash of each image you have. The hash (a short hexadecimal string) is compared to a list of known CP image hashes, and if it matches, then your image is uploaded to Apple for further investigation.

A devastating scenario for such a system is if an attacker knows how to look at a hash and generate some image that matches the hash, allowing them to trigger false positives any time. That appears to be what we are witnessing.

As a human I find dealing with going around emergency vehicles at night is a bit troublesome. The emergency lights are overwhelming and obscure your vision from other things, like some worker near the vehicle. Also the human distraction that is target fixation can sink your attention on the emergency scene and distract you from checking your lane to see if it's clear. I don't think this situation is limited to tesla...
Not GP, but I assume they mean "choose a random task, partition all other tasks on more/less important than it, recurse (probably only for the 'more' taskset)".

This doesn't really feel like a full sort of tasks. Insertion-sorting the tasks does, and so would trigger the "oh no all of these are important" reflex sooner.
Not sure about how the situation is in the States but the people driving those quick delivery vans over here in Eastern Europe (and over much of Western Europe, too, my country is in the EU so their companies can send them anywhere from Varna to close to Gibraltar at a moment's notice) have a very, very tough life, with many of them doing 14-16-hour driving stints. Apart of the huge stress that entails and the accompanying health conditions many of them also get into fatal road accidents because of said overwork and tiredness.

Fortunately the work of drivers driving big lorries is more tightly regulated with the worker's wellbeing also taken into consideration so that there's a fixed time interval per day you are allowed to drive, after which you have to literally stop at the first parking spot at the side of the road, no matter what the boss screams in your phone from half-way across the continent.
"Any" implies the entire world, including the top universities. So more than any university is also more than all universities.
> My position is 100% fungible. I write code to solve problems. There are thousands of people that can write equivalent code to solve the same problems.

Gold is fungible. You can mine gold anywhere in the world and it's worth the same.

The level of skill to be able to code effectively is not something a large proportion of the population has. People have scoffed at the idea that programming requires a high IQ (let's call it what it is), calling it elitist or something, but you don't expect any random joe to be able to be a professional illustrator, musician, juggler, diver, climber, writer or mathematician.

The real problem, has Jordan Peterson points out, is what will society do with people on the low end of the IQ curve, as more and more skills are required and unskilled labor is being eliminated by technology?
It must be hard to do double-blind studies about caffeine, since at a typical dose it’d easy to tell the difference between caffeine and a placebo.

Both the headline and the HN title (which is slightly different) use "is suing"--which is a tense in English that indicates an ongoing or even perpetual action--in a way that doesn't in any way imply direct causality on the nested prepositional phrase "that can / does just that": Apple is, in fact, suing--and has been, for a long time now!--a startup that not only "can" "vet its CSAM tools", but "is doing just that" (which maybe itself needs explanation: "just that" doesn't mean "only that" but means something like "emphatically that" in this context).

Why is this good? How does the extra work make software more robust?
When a package lands in Debian Sid or in Fedora Rawhide, there is a group/subculture of nerds who like to inspect it and report any misbehaviour. [1] [2]

I usually do this directly on the source project, but some people in this subculture do it in their distro.

Also I'm surprised your packages landed in Debian/Fedora, because there is a review process… I'm not talking about a ppa repo or a copr repo, anybody can run that. I'm talking about packages in the official repositories. Installing software from a random ppa or copr repo is the same as curl | sudo sh, nobody vetted this.

Several articles stated that given a perceptual hash you could somehow reverse it into a (very) low resolution image. However the README provides an example hash and it's only 24 characters. How is that possible?
What jumped out at me (again with these business models) was this big tech swing toward the "company store" model:

> I think YouTube is Google’s only product that 99% of people cannot replace.

What about Vimeo? Or for a more federated approach, PeerTube?

From the last conversation I had around PeerTube, the main objection I got was that content creators would probably lose a bunch of traffic which they switched, which is true, but that's effectively the same argument as the hassle involved with switching off Gmail.
I've been in that situation as well. It's not like signals can't be wrong. Question is who do you want to hire, someone with no experience or someone with some years doing the job?

> ...and I'll wager that the vast majority (90%-ish?) of the working-age and almost-working-age population in your country is both unqualified to write software professionally and is not interested in spending 2-4 years of their life to study CS or SE

You left out the most salient point here, most people are entirely unable to write software even if their life depended on it. Just like I doubt I'd be able to write a symphony in 4 years even with a ticking time bomb strapped to my skull.
It was one of my favourite course at uni, I'd love to get back into doing something like that at some point.

I live in, arguably a good part of Africa, and even here it would be a stretch. Infrastructure and "throw money at the problem" type solutions don't work great in rural areas even if you have local communities buy in and assistance.

You're better off just giving poor people here free electricity, which a lot of places do.

>> they make a lot of sense for creatives

I am a professional creative and use Apple’s software for that professional creativity, in the form of Logic Pro mainly as well as Final Cut.

The iPad’s offerings of GarageBand and iMovie are about as useful for me with the work I do as ProCreate vs. MS Paint.

No - the iPad isn’t good for ‘creatives’, it’s good for people who do digital visual art or design.

That’s...for creatives? On a pro level? Honestly it.

It is super shameful that Apple’s own Pro software won’t run on a device they are calling ‘Pro’.
Neither the headline nor the HN title say that the lawsuit is "for saying" anything... they both merely--and very correctly--claim that Apple "is suing a startup that does just that". Are you claiming that Apple is not suing Corellium? Alternatively, are you claiming Corellium does not "do[] just that"?

* OP choose to write and publish a book.

* It's subject matter makes it very clear there would be angry people.

* OP choose to publish this under a name that is linked to lots of other people. Instead of a nonsense name linked to no one.

There are lots of things OP chose to do. The harm being done is partially at the hands of OP. OP isn't entirely blameless here and other people are getting threats and harassment because of OP and Google, but mostly because of OP.

I get that it's a hard subject but if you're going to go write about a cult either do it completely anonymously or do it publically. This middle ground stuff OP is trying is clearly causing harm to other people.

Love the relevant xkcd! And to reply to your point, simply sending unsolicited CSAM via iMessage doesn’t trigger anything. That message has to be saved to your phone then uploaded to iCloud.

Interesting. There are already a few studies about caffeine and the brain-- while drinking caffeine can decrease the chances of dementia, this effect reverses if you drink too much(over 6 cups day)

>In the CAIDE study, coffee drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia/AD by about 65% at late-life. In conclusion, coffee drinking may be associated with a decreased risk of dementia/AD.

It just seems to me that there are two very different conversations happening at the same time, with people swapping back and forth between them

1. There can be false positives or other mechanisms for innocent people to get flagged.

2. It is bad to do this sort of check on the local disk.

The discussion at hand started as entirely #1. But now you've swapped to #2, talking about government spying on local files. It makes it very difficult to have a conversation because any pushback against arguments made for one point is assumed to be pushback against arguments made for the other point.
> Say F[x] is the vector space of polynomials in x with coefficients in the field F, and F[x,y] is the space of polynomials in the variables x, y. For example x^2 - x is an element of F[x], and yx^2 - y^2 is an element of F[x,y]. Then it’s not hard to see that as vector spaces, F[x,y] is isomorphic to (F[x] tensor F[y]). A tensor in this new space is precisely a polynomial in two variables.

I think I'm missing part of the argument. So we have a polynomial p in F[x,y]. The claim in my previous post basically says that there's always a way to associate p with a linear map that takes two elements of the dual space of F[x] and produces a real number. I don't see why that's impossible here.

No. The two methods are qualitatively equally good. In both cases, some outputs have probability floor(2^n/K)/2^n while others have probability ceil(2^n/K)/2^n. The numbers of outputs with each probability are such that they average out to 1/K. The only difference is the distribution of which output numbers have which of these two probabilities.

There is in fact another definition of “tensor rank” which has everything to do with the rank of a matrix. For a tensor t in a tensor product of vector spaces VxW, define the rank of t to be the least number of summands possible in an expression t = v1xw1 + … + vnxwn.

If t is zero, then it rank is zero. If the tensor product is Vx(dual V), ie of type (n,m)=(1,1), then a tensor t can be considered as a matrix, and its tensor rank is the same thing as its matrix rank. You’re basically looking for the smallest way of writing the matrix as a sum of outer products of row and column vectors.

If you’re into quantum physics, then tensors of rank 0 or 1 are non-entangled, and tensors of rank 2 or more are entangled states.
