porous border with Mexico? and by the time it arrived it was too late.

if you say Mexico is in your definition of North America then it should include all of central america, almost all these countries have a lot of land-based trade.

In Canada we have not had any cases related to truckers, but there's a lot of them who have to do the cross-border route, as well as people who commute daily across the border. heck in Canada and the US there are a few spots where crossing the border is necessity -- the only school is in the other country, nearest hospital, the local library, a popular golf course, etc.

or places like point roberts, extremely small but extremely isolated, or Hyder, Alaska.
Then again, incumbent losing election in USA is historical fail. Losing popular vote twice is too.

Back in the good ol' days, you could just take the exam inside of a VM. The VM is locked down, but the host isn't.

Looks like from ProctorU's docs[1] that they got around to probing for the (blatantly obvious[2]) signatures of a VM and stopped that trick.

I wonder if those signatures exist in a Windows Sandbox[3] instance, or if you can detect/block the Enhanced RDP Session Windows leverages when running a Sandbox...

Someone who is worth $15B would be very well-advised, and if he's been thinking about doing this in the past, his advisors may have decided that now is the right time to pull the trigger. Also helps to have plenty in the news these days, to avoid becoming 'the story' on a slow news day/week.

Games code is very often about objects interacting. Especially the expensive stuff (collision/physics and then probably AI). Games don't use global state, because they use C++ and everyone is so bad at programming, but because that's what fits the problem domain.

The idea is that you create questions that are ungoogleable. Most of my upper-level CS courses had take-homes that were open-book, open-internet, and the professor basically said “good luck finding the answer to this problem online; you will not”.

This is harder for professors to do, and maybe fails in intro courses, but generally is quite effective.
Most people are living either in poverty conditions, or can see themselves living in poverty if anything goes wrong. Consequently people are understandably very reluctant to give up any of their precious limited resources. And yet, despite that, everyone is expected to get things done, to show they're interesting and creative, and to build social capital by being useful members of society. These antagonistic forces end up making many, many people very unhappy, and that comes over as entitlement.

Society is broken. It might not be fixable.
I agree with your statement even though it seems to completely miss the original point that I have made.

Yes, you are correct, if you are running a suid binary and you specify / as a temporary directory instead of the default that looks like /tmp/foo-12345abcd/ in its configuration file, then the script may invalidly perform cleanup by deleting everything on the filesystem.

But this does not suddenly mean that Unix pathnames are Turing-complete or Turing-incomplete or that Turing-completeness somehow applies to strings as data formats.

It's not the path string that does the deletion. It's not the path string that was written in a programming language that performs the unlink() syscall. It's not the data itself that causes people to curse loudly.

Sure, secure your data, validate your inputs, ensure that your code cannot be misused, just don't say that data, even when it is in use, performs some computation on its own.
GraphQL, from what I see, is a solution designed by tech that is still best meant for big tech. Facebook had their reasons for coming up with it, because their user base is hitting the billions in scale.

"But my mobile app makes too many requests!" says the hopeful engineer, "and graphql means we can optimise the network!"

Well, yeah, it probably looks like that when you see one nice request from the browser dev-tools, rather than dozens, but that's not what it will look like on the server side, or in the database, when you can get into situations with quadratic queries, never mind N+1. And yes, I've seen that with my own eyes.

If you're sending a dozen or so requests to the server to render a screen in a mobile app, then the slowest thing might just be the stage where you spin up a connection and do the old TLS dance. Unless you're hitting Big Tech scale that's probably acceptable versus the insane amount of money you'll dump into building and maintaining a GraphQL-based architecture without any data proving that this approach would actually be an optimisation.

Just like Kafka, Kubernetes, etc. which have come out of incredibly large-scale projects and businesses...you don't have to and shouldn't use this stuff just because it's the popular thing to do. Startups and small businesses became successful without any of this.
Morality != Legality! No sane person is advocating for ex post facto laws but it's wrong even if it's not illegal. He's been given every opportunity in life, accrued a net worth equal to the sum of 140,000 median Americans, then gives barely any of it back and apparently may flee to dodge being taxed on it.

> If we want to change the law, we should be forced to consider the effects on the future

Of course. This is why it's taken so long to come up with laws that prevent the kind of exploitation that creates a couple dozen billionaires while stagnating the majority of America's incomes. It's morality that drives the lawmaking -- since everyone has different morals and we all live under the same laws -- and at least if everyone hates the guy for this then hopefully we see some laws that prevent more behavior like this in the future.

> the natural assumption would have been that ActiveRecord model classes should double as GraphQL result objects, and there would be a nice DSL for specifying how to safely expose those objects to the API.

GraphQL-Ruby Types _is_ that DSL. You specify what fields can be exposed to the world and this is also the place where you can hide too low-level specifics (e.g. join separate `amount` and `price` columns into specific `Money` type). Then you pass AR object to GraphQL-ruby and it does what you said in DSL.
Absolutely. Im just saying Schmidt isn't an idiot and probably has his taxes in order. This Cypress citizenship might be an effort to evade taxes but I would be surprised if that was the major reason.
I was pleasantly surprised with bat, I expected it to be overkill but it has made its way into being aliased to cat.

What would be kind of interesting is if it would read vim colorschemes, so your cat output is syntax highlighted like if you were editing it.
This open source chip is an FPGA with all the cost and speed limitations that carries. What would it take to create a truly open-source chip?

Said the guy in his 50s.

Mick Jagger who claimed he would rather be dead than singing "Satisfaction" at 40 seems to have changed his mind on the subject now that he is in his mid-70s.

I'm sure when The Who sang "My Generation" years before I was even born thought the same. In that song they famously wish to die before getting old. They still tour to this day though and still sing "My Generation" with band members now in their mid 70s.
Every negative review i have tried to leave on Amazon has been denied for similarly vague reasons. This is not a new trend and goes back at least a decade. Receiving damaged products, wrong products, overtly used (skin buildup on "new" keyboards, etc).

While this should represent a long-term concern for Amazon but it is not a short-term one. For now they are benefited by potential buyers viewing their products as superior.

Incidentally, Amazon's real failure for me as a consumer is their delivery service. In spite of spending hours on the phone with their logistics departments, Amazon's delivery people have a roughly 33% success rate getting a package to my door, compared to nearly 100% for USPS, UPS and Fedex. This has diverted thousands of dollars in the last year alone to other vendors or in-person stores, as i preemptively avoid the frustration associated with waiting for a package that never comes and then having to chase down a refund or another shipment.

Hi HN, author here. A few comments on how I came up with this idea. I've been trying to find a "proper" connection between audible sound and visible shape, a connection that would not only preserve all the information, but would also properly visualize the "symmetry" in sound, so that messy sound would turn into messy images and harmonic sound would turn into visually appealing images. The latter part is hard, as perception of "musical harmony" is vaguely defined and subjective. Nevertheless, after quite a few attempts, I came across a particularly simple FFT-based technique that produces impressive and unexpected results. Below is the summary of my finding.

Music is a temporal ornament. There are many types of ornaments, e.g. the 17 types of wallpaper tesselations, but few of them look like music. However there is one particular type of ornament that resembles music a lot - I mean those “mandala” images. I don’t know how those are produced, but I noticed a connection between those images and music:

- The 1st obvious observation is that a mandala is drawn in polar coordinates and is 2PI periodic. Sound is periodic too, so I thought the two facts are related.

- The 2nd observation is that patterns on those images evolve over the radial axis. Ans so is music is a sequence of evolving sound patterns.

- The 3rd observation is that a 2PI periodic function trivially corresponds to a set of frequencies. We usually use FFT to extract the frequencies and another FFT to restore the 2PI periodic function. Thus, a single radial slice of a mandala could encode a set of frequencies. If this is correct, a mandala is effectively an old school vinyl disk.

Putting these observations together, we naturally arrive with the idea of using ACF. More details in the linked github project.
Schema duplication also exists in most of the popular python implementations I’ve seen although I don’t do much backend right now I might be mistaken.
As an aside: anyone know what this documentation was made with? this looks like it would be great for dev docs.

I think Rust is actually pretty cool and I have tried it myself for a few small things, but it's definitely the most obnoxious programming language community out there (which does not mean, at all, that everyone that is a part of that community is obnoxious).

Travel Startup 2020
Hi everyone! Would love to get your feedback on this MVP that I launched 3 months ago. The idea is to build a platform where experienced travellers share their itineraries and inspire those who want to visit same places and help them figure out what activities they could be doing. I have about 35 content creators onboarded but the traction is not there yet. Once I get more data I plan doing smarter things. What is your feeling? Is it worth it?
You're right! Let's keep doing what we're doing. It's working great.
Of course the number seems high if you focus on a particularly vulnerable group. All that matters is the IFR across the entire population, as the entire population is being harmed by lockdowns.

A 3d-printed hand device "shrinks" your hand to child-like proportions, giving you the ability to feel various objects as a child-would.

It is expected that this relatively cheap device can be used to better design interfaces for children.

> HandMorph presents a unique spin on wearable technology, because no computers, electronics or virtual reality devices are involved. The device is 3D printed with just a few dollars of materials, and slips on to its user’s hand like a glove. Through tiny mechanical links, the device translates hand movements to an attached small silicone hand and provides realistic haptic feedback. A wire between the glove and the user’s waist adds to the experience by restricting reach to the range of a small child.

I've been watching his videos for a long time and as far as I can see, the goal is never technical sophistication or doing things in a "production ready" way. Rather, it's making the innards of a computer understandable. The way that he did it here, he could easily explain when and how the CPU had control of the bus and when the video card did _and_ he had a picture that he could point at to visually explain what was happening.

I've also noticed that he'll start simple and then layer on more complex things as the series progresses. No idea if he's planning on doing that here, but a good example was with the 6502 computer where he implemented it out of the gate with no RAM so that the video could focus on getting things up and running.
