Hmmm, it's tiny... but what about a bigger matrix of LEDs that can be moved around just a little bit. The idea I guess is time-multiplexing lights in space... So if you have a big board with a grid of LEDs and shake it around a bit, you can do the same thing but with less movement and more lights... You get more pixels for the same number of lights.

(Hopefully someone can visualize what I mean.)
> Sometimes that’s using psychological tricks to influence shoppers’ behavior.

Which means shoppers have an incentive to look for such tricks and ignore them, or go somewhere else to shop.

> Sometimes that’s good ol’ fashioned buying out the competition.

Which in a free market basically doesn't happen unless the competition is genuinely failing to compete.

The reason such things happen when the competition is genuinely competing is governments messing with the economy on the theory that top-down dictation of policy is necessary. For example, big box stores and chain restaurants have access to cheap loans using government printed money that smaller mom and pop stores and restaurants don't. And then we argue over whether we should use "merit" to give out the cheap loans using government printed money, or something else, when what we should be doing is preventing the government from messing with the economy in the first place.
"So to speak". Precisely directed, anyway.
I don't think multiple choice tests and project-based assessment are in conflict. They are both useful tools for evaluation. Multiple choice tests can allow a student to evaluate himself to make sure he has the base level of knowledge required (facts and application) in order to develop mastery. I do think it's useless as a grading metric, even discounting cheating issues. Project-based ability assessment is useful both for gaining mastery (with timely expert feedback) and for evaluating a students' mastery. I think project-based ability assessments for grading purposes ought to be coupled with a conversation about the project so the student can explain/defend his or her choices. As a side effect, it will help prevent cheating by having someone else write your project.

In your particular case, I'm glad you had a good professor that allowed you to spend otherwise wasted time learning. However, I can't help but feel you should never have been forced to take (and presumably pay for) that class.
Yep exactly right. Do as much as you can with plain HTML, CSS and JavaScript. Learn the basics without depending on any packages. And only then maybe add a package if it really absolutely is worth it compared with writing a bit of extra stuff yourself. Every build system or package you rely on will become a liability and a major pain point down the road. Guaranteed.
there's a saying in trading: never lose money being right
I totally agree with you. It is a cliche, but truly, they are only cheating themselves.

Careers eventually filter out (most of) the cheaters. From my observations, only the students who were committed to understanding the material went on to have superb careers, with maybe a few exceptions. The rest ended up in dead-end mostly-mindless work, or dropped out of STEM-related fields all together.

I have a concern for the future of our society when the majority of an entire generation seems committed to cheating, though.
If I go to school for computer science, but have to take chemistry, statistics, etc. And get stuck with a bad professor who spends half the class time ranting about irrelevant topics, cheating makes sense so I can spend my time focused on the classes that matter to me.
If your talking about the CCR2116-12G-4S+, its a nice router with the AL73400, which is a 16 core A72 platform. OTOH, for a general purpose machine roughly in the same ballpark your probably better off with the NXP LX2160A on something like the solidrun honeycomb. The latter is more suited for general purpose compute given the pcie slot, sata, m.2 slot, pluggable ram, etc. Its also 16 A72's, with the advantage its a systemready certified platform.

But, those are really old generation parts given there are a number of A76 based systems appearing on the market. Those chips are a giant step above the A72 based machines the same way the A72 is a big step above the A5x ones. (aka its a gravaton1->gravaton2 kind of step, or the diff between atom and the mainstream i5/7 parts)

Edit: Notice the G1->G2 uplift in single threaded perf.
https://www.anandtech.com/show/15578/cloud-clash-amazon-grav...

That is going to be the uplift going from a A72->A76+ platform. The IPC is nearly 2x, and translates to going from a early 2000s era x86 to something fairly modern.
Isn’t that a lot of what’s cool technology is?
As a southerner I hate this shit, seriously a poisonous attitude to have towards such large and yes, diverse groups of people.

The south is like a quarter to a third black! 30 million or so queer people live down there. It's the most populous region of the united states and the home or origin of gigantic swathes of organic american culture.

If you feel like things are going badly down there, you should reach out in solidarity to southerners, because many more of them agree with you than you are encouraged to think. Segregation is still basically a thing, tens of millions are disenfranchised and intentionally impoverished. It's more correct to think of it as occupied territory than your enemy. The shame we should feel is our own, for letting this continue against the wills of so many who live under it.
Sadly he passed away in 2020.
The argument is for a 2D observer.

You and I both see that the surface area of a sand grain, distributed by explosion to a different surface area with the diameter of a beach ball, has a center in 3D space.

But from the perspective of a Flatlander on the expanding surface, looking at the distance to an adjacent microbe, the universe is growing, and there is no meaningful point on that 2D surface from which the expansion emanates, it's expanding everywhere.

There's no reason to believe our universe is not infinite. It's certainly effectively so.
For that one semester, until the cycle repeats itself. Smarter students in the future won't allow their professor to join the class chats.
> they are only cheating themselves.

I disagree. They are undermining the value of the qualification other have earned.
Since a plurality of the population has higher education degrees and since that segment of society enjoys greater respect and privilege, I'd wager that instead those with higher education will use their positions and voting power towards the passage of laws and regulations to keep the self taught out of the workplace.

You can see the start of that here sometimes. It is sometimes suggested programmers become like "real engineers" by increasing regulation and requiring a certain level of education.

I mean the fact that we are having a serious discussion about forgiving trillions of dollars of debt for this statistically already quite privileged population shows they have to power to pull it off.
> No, a subgroup of students surround themselves with cheaters and believe everyone else is cheating.

It's exactly this. I didn't cheat in college, I've always hated cheaters, plus obviously I didn't want the risk of potentially being caught. People I was friends with in my CS degree, to my knowledge, didn't cheat either. Maybe they were cheating and I just didn't notice or something, but I think it's unlikely.

When I was an undergrad TA for our intro CS class, we did have to deal with some cheaters, but not that many. Either it's because it's BYU, where the level of honesty is higher (I'd lose stuff all the time, and even laptops would show up at the lost and found), or we just sucked at finding the cheaters.
I am not an Uber fan in terms of their ethics and how they got to where they are. That said I think disrupting taxis was a good thing, for the consumer.

The medallion ponzi scheme is dead. You now know more about your driver, I presume it has made things safer. It has allowed people to do rides as part of the commute they are doing anyway, so probably good for the environment. It has encouraged ride sharing. It may have made some people not buy a car where they would have before, which is probably good.

The rideshare is probably a good example of real value being added. A lot of pure "internet only" marketplaces are just seeking rent on some subset of ecommerce. At least Uber added a map, routing, automatic pricing and stuff.
This looks really good. I ended up quickly slapping something [1] together myself to get this kind of insight for my project.

Some feedback though, I found it really hard to understand what the cost would be for "Trying my own dataset" (After the first year) and how TiBD factors in and would be used. All obvious links for TiBD go direct to a signup page which I don't want to fill without some understanding/validation of the service I'm signing up for. Removing the path of this signup page, in an attempt to go to the root URL to learn more, then takes me to an Auth0 access page. I appreciate I may not be your target market, but just giving my view of someone thinking "This looks cool, how much would it cost to have a customized version of this?"

> I have a concern for the future of our society when the majority of an entire generation seems committed to cheating, though.

The COVID pandemic makes me worried about this even more. It's gotten really bad, I can't imagine how bad it's going to get when the generations it affected reach college. Maybe I'm overestimating it (if you cheated through HS, you might not go to college), but there were already clear trends that are definitely going to be exacerbated.
Gogoro to Launch Smart Scooters, Battery Swapping in Israel in 2022
To be fair, that sounds like a problem with your infra. There are plenty of enterprises running Postgres in Docker/Kubernetes successfully. A lot of technical problems are not the stack or the engineer's capability, but the company culture and lack of funding, time or resources. If you had more of all 3, im sure your problem could be "solved" to an acceptable margin of error. Likely by you.
True, but I think the target should be that wages rise at the same rate (over the medium term) as productivity. If wages rise higher for a year, it's not an issue. But inflation (including wages) has been rising for well over a year now.

Now, it is also true that if wages rise slower than productivity, that should also concern the Fed, and they haven't been as concerned as they should have. However, given that they switched to a positive (2%) rate of inflation for their target a few years back, they are at least acknowledging the problem. But I agree that wages rising slower than productivity ought to be acted on as well.
They're talking about an intro class, so doing beginner level OO stuff isn't exactly surprising.
I have never been to the USA but know of the place too much (and very superficially of course) from media consumption and everything getting Americanised - from alien invasions to pop songs.

Anyway, this comment reminded me of The Handmaid's Tale.

That’s lumping a lot of people together and alienating them. Liberals are doing that plenty in my home country right now.
The official story is that Brave runs a revenue share program, so if they wanted to use "real money" they would have to be a licensed money transmitter. To sidestep the regulatory issue, it is much easier to use a cryptocurrency for the payout and punt all the KYC/AML requirements to a crypto exchange.

"Why BAT and not just use another existing crypto?" Well, they tried! They started with Bitcoin, but no one wanted to use BTC to tip or contribute, which is kind of a problem if you want to build an alternative monetization strategy for content creators.
statistics is pretty useful in computer science...and as someone has has worked in biotech on the software side...chemistry can be as well. Heck even anthropology and philosophy were pretty relevant when I took my courses on NLP years ago.
Actually if you look at Ariel Ekblaw's proposals in a different article / medium, many of her designs do involve the 'cellular'/'connected closed chambers' nature you describe. Highly recommend the Lex Fridman podcast interview linked in the other comment!
This brings back memories. Megaman was the only game I had for my gameboy, and I remember playing it for months. Back then I barely knew english, I would spend days trying to figure out what it wanted me to do. By trial and error, I would make progress. So story is still a mystery to me. I should def pick it up again.
and they want to clip the ticket on content. Why let people add custom skins to a game when your making money off gun textures
That sounds like a great option, though I imagine offering an alternative objective like that will get harder to do as the course difficulty/level increases.
I'm really torn on whether this was handled right. A real thing in the pandemic is that everyone was cheating all the time, at every level. Students looking at there phone when they weren't suppose to, printing things out, being in various chats, whatever. It seemed sort of the norm at the time I would say realistically.

Reporting someone for academic dishonesty is a deathblow to any kind of application to higher ed. This was an undergrad psych class I think? Anyone there trying to get into the PhD programs is in for a world of trouble now, that's a competitive place.

It's not that I think cheating is good, I just wonder if these students peers in this class/other schools who had better outcomes did things the right way, or maybe they just didn't have a professor who enjoys this so much that he will spend weeks writing R code to fully catch everything. That seems like an arbitrary way to have a dream end, I dunno.
Any business on Amazon that uses AWS has to “pay” for AWS services as part of its cost of doing business. It’s counted as AWS revenue and an Amazon retail cost.

https://www.lastweekinaws.com/blog/the-aws-service-i-hate-th...

> For example, internal AWS accounts are known as Isengard accounts, after the fortress in “The Lord of the Rings” eventually controlled by the corrupted wizard Saruman. When internal game development teams use Isengard accounts, they must pay (via internal accounting) the same rates for AWS compute cycles that outside retail customers pay, according to people close to the teams.

You will often here Disney talk about “transfer costs” to Disney Studios from Disney+ when talking about Disney+‘s content costs. This is similar.
For what it's worth, I feel similar to you, including for sports. Basically, life threatening things should be prohibited, but everything else is free-for-all.

This would eliminate a lot of cheating, and a lot of advantages for those in a good position (better access to new drugs and nutrition, better recovery programs, better training programs — aren't they all unfair at some level?)...

The ultimate goal is to get us to experience the top level combination of talent and effort, both in science/work and otherwise. Getting there is never going to be completely fair (hey, you scored better on it even though you prepared for 3 days and I took 30: tough luck for me, I guess, but the fact you are more talented for that exam is not something I can do anything about).

I've also seen non-cheating people who are excellent at exam taking (great scores) without ever taking anything from the actual material (zero learnings). I've never felt threatened by them either, though maybe I would have if I wanted to pursue an academic career.
It is nice to hear a defense of this style since there’s often so much complaining about it, and the tips to mitigate the downsides are useful.

Personally I don’t mind a whiteboard session or two during a loop but what’s wild to me is how, especially at big companies, you’re expected to do four or five of these to get an offer.

How often do these companies decide “well they understand when to use DFS and they can merge-sort a linked-list and they knew to use dynamic programming but we can’t hire them because they couldn’t remember how to implement a heap”?
It depends on the class. Many "intro to OO programming" classes are really "intro to programming" that happen to use OO. There are no or low-level prerequisites, so the class often has to accommodate learners who have never so much as written a hello world script. (There is also pressure for higher level classes to dumb things down so the students from the lower level classes don't reach an insurmountable cliff, even if it's only insurmountable because the school's earlier classes have failed them.)
A lot of the students (and people in general) have a low-level cleverness obsession which handily blocks out high-level perception like that.

Then the blocked out part becomes neglected so it turns kind of on/off in nature. It now gives you either super great or awful information.

So as a result, it's not that you don't see the big picture. It's that your inadvertent feedback loop converted high level thinking into a huge scary monster of high-level disasters that will seemingly result if you aren't as clever as can be.

This also explains the cleverness in the face of everything else. Caught? Email back and be clever. Etc. Don't ever stop being clever, caught or no. It is your only (seeming) chance.

But did you also catch the high level thinking student who was feeling stuck and potentially screwed, in their honesty? They realize the system might just as easily punish them. They are also lucky the professor had a considerate perspective rather than a blanket-projection attitude that many have. They are also lucky they weren't randomly selected by the cleverness cabal...

(Also notice that really good professors make for reliable bridges between high and low level perspectives, with expectations of the former but also multi-dimensional empathy for those living the low-level system. This professor is indeed a very clever person on their own. So for them this is situation is probably less likely to result in massive disillusionment as it would for pure high-level folks.)
Sometimes a "curve" can be a test that isn't norm-referenced, but instead just curved up on a straight static curve. For example, 10*sqrt(n) on a very difficult final can provide a grade boost to lower grades. It might be easier to just raise grades than to modify the test, if you see students that you feel should have passed, fail.
Do you mean that it's not on your CV, or that you don't send out CVs?
Thank you, I'm open to this collaboration:). Seriously, I appreciate you sharing your perspective and reminding me not all the brains there subscribe to extreme idiocracy.

I am eager to see the minorities in TX get more involved in politics and help restore sanity.
Some people learn better when instructed, classes bring structure needed by all but the most self motivated, and some things are very difficult to learn without engaging with instructors and fellow students.

The thing university seems to do the most these days is weed out people that don’t have the resources or ability to navigate the game put together which doesn’t have that much to do any more with education. A liberal education was by definition intended to make one free, now university is quite a lot about initiating people into wage slavery by putting them in serious debt and only graduating people who are good enough at following rules in complicated somewhat pointless exercises. It is unclear if this process is shaping or shaped by our economy.
An undercover cop, dressed as a skateboarder, watches dozens of others skate for months - unimpeded - in a location where trespassing is a gray area.

What should have happened?

A. The cop tells the skateboarders, "just so you know, you're technically not supposed to be doing this. If you do it again, I'll have to take action."

B. He suddenly arrests the skateboarders for trespassing, much like a sting operation.

The professor needed to say something. Period.
> Princeton telling people they can’t get ahead on merit is …

> I don’t even know the word for it.

You're suffering from a cognitive malfunction: you seem to think that "Princeton" is waving its finger from a lectern, when it is in fact not making a statement at all. You're just reading an article in some kind of publication published by Princeton University Press.
It can be both. You can learn and earn those credentials.
huh. i am a proud cheater. the entire chain of command, from local bureacrat to the chief of fed, and all company execs are cheaters. so why not me? I'd be a fool if i didnt trick the system.
The fact that Stigler's Law adheres to Stigler's Law is hilarious. Thanks for sharing!
As someone with 10 years as a software engineer I haven't needed it.
It wouldn't be possible until around 2024, and regardless TSMC has a ridiculous ARM ecosystem. IFS is probably most competitive with RISC-V and licensed x86 cores rather than ARM. That said, IFS apparently does Graviton packaging, so maybe?
Yeah, fair.
Both termination and verification go beyond NP completess, in that they are undecidable. Also, "verifying so[m]ething with... confidence... lower than 100%" is known as testing.
How "current" was Fukushima, and why could they detect traces of radioactive material in California?

I'm not against nuclear, but can we please not build them in places that present unnecessary risks?
Maybe that's true only because the author posted this, though. Hopefully the course changes that the author made will encourage future students to actually spend time on the course. If that's true, does it point towards a deeper solution with making courses more engaging? Not that students cheating are the professor's fault, of course. Nonetheless...
> Nirvana fallacy. The point is that it can be much better and eliminate ALL non-design bugs.

Serious question: do you really believe that?

> That's just stupid. Show me the studies.

There is a kind of HAL-9000 quality to many of these arguments. Formal verification is perfect by definition. The fact that it hasn't had very much impact in the real world is all the more evidence of the world being full of wicked people.
I personally find cheating repulsive. Are you not bothered by the lack of integrity?
Students are mostly not that interested in learning
Not for nothing but we have plenty of slow coders that are “low volume” but some of the most diligent and edge case counting engineer’s I’ve ever met. Even then, if the business doesn’t depend on everyone working like a banshee, my team may as well take their time.

Even as their manager it’s not my job to lead a death march.
Thanks for sharing these examples. I feel like stories like this, collectively, could constitute an interesting book.
Academically universities are to teach you how to think and do self-directed learning. They also socialise you for the knowledge workforce by widening your horizons.

Testing is a distraction from their core values. And a crutch for handling the poor student to teacher ratio.
In Germany (as far as I know), quizzes and homework are not graded, only some % of them needs to be completed in order for people to be admitted to an exam.

Having a similar system would work well there, if one can make exams (and midterms?) either physical or less susceptible to cheating.
The valve strategy is simply to co-opt them and give them a piece of the profits. (e.g. TF2)
Further evidence that they didn't necessarily even realize they were cheating - aside from the exams - and that the professor should have spoken up sooner instead of playing undercover cop.

He got off to the power here, and you can tell.
