Hello HN!

I'm excited to introduce our project, Dacade https://dacade.org/ - a free, peer-to-peer learning platform with a focus on Blockchain technology. The main idea behind Dacade is to provide a collaborative learning environment, where people are encouraged to build amazing Dapps, give and receive feedback on their submissions, whilst earning crypto rewards along the way!

We also recently launched a new course in partnership with the Celo Foundation, where participants can learn how to write smart contracts in the most popular smart contract language, Solidity, as well as build a front-end in vanilla JavaScript and connect it to the Celo Blockchain. Check it out here: https://dacade.org/communities/celo-development-101

Our goal is for Dacade to eventually become fully decentralized and make the code for the platform open source, so that everyone can contribute to the learning experience of themselves and others.

We'd love it if you could give our platform a go, try out a submission (or two!) and let us know your feedback on it.

Feel free to join our Discord server if you want to find out more and connect with the Dacade community: https://discord.com/invite/P74DGkhw
The pod-style boxes had an even greater rate imbalance in my experience a few months ago. In fact, I couldn’t even get a pod from PODS and had to use a different company.
Talking about the Netherlands: when I got the theory part of my motorcycle license, I had to learn (and got tested on) all sorts of crazy traffic situations involving sidecars. Of course, I have never seen one in my entire 4+ decade life.
This semester all my exams are open note, no proctoring. I think it is harder for professors to write a good exam this way (they need to make the questions things that test understanding instead of just recall.) I’m certainly doing way better with this method, but I think I am still learning the subject just as well as I would in the “old” method of stressful proctoring and memorization.

It seems like with software, you could easily write math questions with different inputs, as you suggest (in fact, our homework software already did that for math last semester), but it seems that those tools are not built into the testing software so much. It definitely seems like a solvable issue though!
This is correct. Also tends to be more expensive as well.

100% compatibility isn't guaranteed for Windows either, you can always get screwed by random driver bugs.

For that, you need a console.
It's possible to execute statements in a lambda through exec. But it's more of hack than what it worth.

Ask HN: Alternative to Paid Gmail with Support?
After dealing with Google Ads support (their core business!), I'm concerned about relying on them for email.

Are there any good paid alternatives that have good support?

My main concern is randomly getting locked out and then getting the runaround from their useless chat support.

If their support is bad when I'm trying to spend thousands of dollars per month, then I can imagine how much worse it is when I'm only spending $10 / mo for Gsuite.
That's a very sad state of affairs. I think that's partly due universities having indeed taken the easy and lazy path of making the least waves possible while collecting tuition fees. (2) is also a product of the current climate in society but that's a wider anbd bigger issue.
When I was TAing last year we had to proctor the students via zoom (trust me its not fun for anyone). Quite frankly I found different professors approached things in different ways. All the exams were made open book, because its impossible to figure out if people are looking at their notes.

One of the profs decided to make it impossible to cheat by basically making the exam so hard that even the A+ students would have a hard time solving it. This worked well in preventing cheating because for the A+ students to collaborate with others they would need spare time. On the other hand it left lot of students very demoralized.

Some of the other profs came up with question randomization schemes. So the assesment tool would shuffle questions for different students. People were still on discord channels but to not much effect. Of course this required that the professors (or the TAs) were conversant with basic programming skills.

For humanities oriented assessments however, I know most of the profs chose to do things via project work (it's a bit hard to cheat when writing essays. You can't possibly have the same argument as someone else so...)

One thing I can't help but wonder is that I realized when we moved things online we missed out a lot on student interaction. Students were generally far more aggressive for their own grades, often at the cost of other students. Furthermore, I found students were far more ready to abuse the teaching staff than when we were physically there. Conversely, teaching staff was far more strict and stressed out than before. I can't help but wonder if the same courses were conducted face to face whether there would be more kindness all round.
He is a complete vaporware salesman.

5) Where are all the self-driving cars?

You only need high-school physics to debunk half of the stuff he comes up with.
It's 100% due to the traditional model of measuring academic performance through the number of published papers weighted (very, very strongly) by the "reputation" of the journal they're published in, justified by the importance of curation and peer review to provide quality control.

Historically, this model grew because the journal publishers provided the necessary infrastructure to print and distribute copies of the articles.
The problem is, "repairable" can have different meanings.

One is the availability of original spare parts like screens and backside covers (aka the stuff that breaks very often) for ordinary people and repair centers. A phone that's glued together and absolutely waterproof as a result can still be called "repairable" under that definition as long as there is non-discriminatory (aka external customers get charged the same as manufacturer repair centers) access to spare parts.

Another is the accessibility of repair without special tools (cough Pentalobe) or the need to discard a fully functional component to access a defective one, e.g. when the screen is to be replaced you need to remove the glued in back cover first, a step that risks permanently damaging it by bending or breaking it. Most waterproof designs have a really hard time here as it's hard to make a waterproof design that is still easily disassemblable and slim/optically pleasing.

The third definition of repairable is if an end-user can replace a common wear item on their own: batteries most obviously, but also outward-facing connectors for headsets and charging/USB.

The fourth definition of repairable is the firmware side - aka, can people repair defects in the firmware like security flaws on their own after the manufacturer has ceased support, without risking to lose functionality. Apple is the worst offender of them all with not allowing "rooting" at all, but in most of the Android world the situation isn't much better - root your device and you'll lose KnoxGuard/TrustZone functionality (sometimes breaking apps relying on it, half the apps on my rooted Samsung don't do fingerprint auth anymore since rooting), and SafetyNet attestation will also fail, leading to apps either stopping to work entirely (banking apps, just f..k off, I know what I'm doing) or offering reduced functionality (Netflix).

And with all of the various definitions of repairability in mind, you will always have some trade-offs to make.
Internal activism has demonstrably achieved a noticeable amount in steering the company to act a bit more morally.

As far as I can tell all of the people quitting have achieved precisely fuck all. Not a single example to the contrary I can think of. Not at a big tech company (at a startup maybe).

Interestingly every time this topic crops up there's a chorus of "just quit if you feel that way about it" as if the exact opposite was true although in reality I think everybody kind of knows it's really not.

From a non American perspective it's really strange watching this play out. Like looking at a culture that cant see the color blue or something.
I don't understand why you wouldn't just define a function if you needed multi lines.
The business property tax is for property over $100k. I don't think many offices have that much furniture. Also, it does not appear to be true that this tax is assessed on businesses outside of la county. Just how exactly are the figuring out who is driving "through" the county? They have to send you the assessment forms.
You are misinformed. Moodle (LMS) and STACK (maths quiz system with symbolic comparison etc.) are open source and fit that description.
I agree that one needs to be critical or corporate videos.
I've watched the video and it is appealing to feelings and has very little technical details.

It impresses by outlining the size and some of the complexity but nothing more.
It does not give dates, cost or other numbers.
I liked it but would like a much more technical documentation too.

Smaller, yes, relatively speaking. But in absolute terms, the gap is still vast, and not exactly closing. (If anything, widening, as we keep getting more and more reliable emulators on PC that give access to hundreds of older console exclusive titles.)

Plus, individual consoles are still randomly cockblocked by exclusive contracts, so you'd need 3 consoles to get all possible content, vs. a multiple accounts on one machine for all the various PC game shops.
They did read that sentence with comprehension. It is you who can't connect the lines. Your IDE already does typechecking and finds other issues for you. Basically the only thing that you are missing is the ability to run and test your program.
That "not being legal" is a corruption, a continued acceptance of lobby dollar bribes to maintain the situation. Or the lawmakers are so capitalistically corrupted they do not see the problem and think paying multiple times for publicly funded research's information is acceptable.
Your belief is contradicted by reality. For example: https://stack-assessment.org/

I read the UC San Diego summary. As far as I can tell, their data is from an online poll. It’s well-known that online poll respondents are generally more interested in politics than average. It stands to reason that those considering leaving California may be much less interested in politics and thus undersampled. I didn’t see this potential sampling issue addressed in their write-up, though I’m a layman unfamiliar with the polling methodology they’ve used.
Careful taking lawsuit claims seriously. Especially then the claim drops from doing X to "attempting X" by paragraph 2 and by paragraph 6 is just being "willing" to attempt X.
This sounds like there is currently a mechanism for winnowing the crap, but we currently don't really have this either.

On the contrary, because researchers are driven to publish publish publish, they often reheat the same paper over and over again with minor modifications, or just go conference shopping until they get an acceptance.

With less publishing pressure, qualitu would go up automatically.

Watson and Crick published papers only every couple years. This wouldn't work today at all.

Science needs to go back to publishing when you habe something to say, not just to fullfill your quota.
Amazon requires you show ID and have a camera on for their online peogramming screening.

I chose to not enable my laptop webcam and to instead apply elsewhere, mostly from self respect.

In paying an institute for education i doubt students have a similar luxury. I hope that the EU might enforce privacy similar to the move against cookies. Likewise i would love to see restrictions that prohibit facial recognition in private businesses without consent
I pay over $6,000 a semester to attend a reasonably-priced state university. While the professors may be overworked and underpaid, from a student perspective, for the money I give the institution, the institution can invest a little in systems that do all this automatically.

International students pay significantly more, and there are often 100 students or more in a class.

So it’s also not a great solution to put the burden of overworked professors onto the students by invading privacy and making them use poorly built suffrage to do so.

The trouble is at the institution level.
Game Over: Chinese Company Deploys Facial Recognition to Limit Youths’ Play
During a public Q&A back in 2017 I asked Woz what he thought about control Apple asserts on their "i-device" hardware. My question was to the effect of "What do you think about how I don't own my iPhone or iPad the way I owned my Apple II?" His answer referenced the openness of the Apple II but also included (not verbatim) "sometimes proprietary is the right thing" in reference to the Apple "app store" and the locked-down nature of the iOS device ecosystem.

To have Woz-- the hacker's hacker-- answer like that was really shocking to me. (I was really, really sad to hear one of my childhood heroes answer in that way. I know, I know-- don't meet your heroes...)

In this recording his position sounds a lot more reasonable. It makes me glad to have such a well-respected voice out there driving conversation about this topic.

As an aside: I recorded my question and Woz's answer (albeit via my phone in my breast pocket, so the audio quality isn't very good) back in 2017. This was from his October 30, 2017 visit to Miami University in Oxford, Ohio. I didn't find a recording available online with a quick search, so here's this:

Also I still can't tell if this article is satire or not.
It's still a bit rough around the edges, as the best compatibility is found in community Proton forks you need to install manually, plus the need for out-of-tree drivers and non-standard bluetooth module config flags to get game controllers to work reliably.

(OTOH, you're stuck with a similar driver mess if you want a DualShock or JoyCon on Windows, so w/e)

But it's gotten a lot better than it used to be.

Product/infrastructure seems exactly as unclear as front/back end. Two lumps with a ton of ambiguity in between.

Is the library that generates buttons and popovers product, or infrastructure? Be careful!

So for the purposes of clarity it’s a wash. But probably it is good to talk about your job in terms of its relevance to the business as opposed to the particular environment your code runs in. That does seem like a better framing in a professional setting.

But the notion of “frontend engineering” is not going anywhere. It is a real subdiscipline or specialization with different emphases than other parts of engineering, just as “data engineer” is for example.
Infamous MST3K episode.

>The writers were unaware of the film's darker content when they selected it for the show, only watching it in its entirety during their usual joke-writing sessions. They were horrified to discover the scene in which Rommel's girlfriend Rita is raped and killed, juxtaposed with shots of Luke and Lois' children playfully roughhousing.
And this will cause issues when you have cable-into-cable. Then you'll have a plug into a plug, with no apparent difference.
The older and more educated I become from free classes online the more ridiculous our education system seems.

I pretty much know if I learned the material or not. A test is nice to confirm this for myself but the way we have put test scores above everything is just ridiculous.

It is all the symptoms of credentialism. Imagine taking the same class for free that you don't get "credit" for. It is not "cheating" then if someone else gives you the answers to things you don't know. It is just a waste of your own time. Why even bother taking the class.

Instead we have people paying tens of thousands of dollars basically to focus on test taking to get credentials that no one really cares about anyway instead of actually becoming more educated.

The irony to me is I always got good grades when I was younger and in school because I have always been a great test taker. I didn't have to "waste" much time actually learning the material. "waste" time actually benefiting from the material.
> For humanities oriented assessments however, I know most of the profs chose to do things via project work (it's a bit hard to cheat when writing essays…)

This is true of copying and collusion generally, but not of commissioning unique work from an essay mill, which is shockingly prevalent in humanities subjects for this very reason. I am aware of no effective defence against this other than in-person exams or oral vivas. I’m glad I’m not a humanities lecturer right now.
OH I don't mean GPU accelerated, I mean that there are video codecs built into the CPU so they don't have to be done in software. That was the killer for my Phenom II.
Yeah, when we left earlier this year the U-Haul prices were insane. We got lucky and managed a trailer cross country for $400 but the price jumped to almost $1000 if we added another day since we would lose the locked in price we originally got.
Having worked as a researcher all my life in academia (but not in the industry), I can not support Sci-Hub. I know it's an unpopular opinion but I think it's the wrong approach.

As scientists, I think we should be held to especially high moral standards. And there are two questions one should be allowed to ask:

1. Is is right to publish research results funded by tax money behind a paywall?
2. Is it right to circumvent a paywall to access publicly funded research results?

And to me, the answer to 2. is imply 'no'. I know that most people, especially here on HN, do not agree with that view. Perhaps they might think that a 'yes' would immediately follow from a 'no' to question 1.

But I don't think it does, and I'm not even sure my answer to question 1 would be a 'no'. Perhaps one could think about another question first: should researchers turn to a professional publisher to get their research published, and I think at least some years ago there wasn't much else you could do. Now, of course, there are digital platforms such as arxiv but their acceptance also depends vastly on your field. In any event, such platforms can also be thought of as a publisher, anyway. The main service provided is organizational: publishers don't review the research contents (they're not qualified for that) but they organize external reviewers; publishers provide discoverability because they are a well-defined source known to the community. Are there alternatives to that type of work? Sure! But there is an added value in what a publisher does.

So then in a follow-up question, we can ask whether a publisher should be compensated for their work. And to me, it is pretty clear that they should be. Of course, there are different ways this could be implemented but that decision is up to the one running the business, ie., the publisher. I can think of more customer-friendly ways than to make me pay for every single download of a paper. On the other hand, there are lots of other businesses where I don't like the way they make money - tough luck for me, I guess.

Now, I think this last point is very important, especially before you go and hit that downvote button (unless you already have): I can think of better ways (for me!) how research publishing should be realized. But I don't think that from that it follows that I should be able to or even have the moral right to circumvent publisher paywalls.

Perhaps it's wrong to charge for access to publicly funded research results but I don't think the second wrong of circumventing publisher paywalls makes that right.

Oh, and here's a little subtlety I don't see discussed very often: if I do research funded by UK tax money and publish it, should that paper be freely available to Americans too, or only to UK tax payers?
> We can debate whether taxes or laws or governments should exist.

It is pointless to debate the need for taxes with the corrupt governments and their taxmen. They make the laws, they have a monopoly on the use of force and they do not want to relinquish their power. The only possible move is to subvert them.

> Debating a thing and actively subverting it are different. Just as subverting a thing and expecting such subversion to have no consequences or response are different.

We know there are consequences. That is why technology must take that into account. They make their ridiculous laws, we make it impossible for them to be effectively enforced. They'll have to stoop to ever increasing levels of tyranny in order to maintain the same level of control they previously enjoyed.

Is there a limit? I don't know. I fully expect them to try to link cryptocurrency to terrorism or something.
I dislike the engineering where somebody thought it was smart to move a hot-loop database call into a self contained class with a static method which connects, queries, then tears down 400 times in a single page load.
Ah okay, but what makes Google great for me is the fact that it contextualises and uses details about me to provide more accurate details.
>In simple words, it’s a slow database.

Huh?
Discord accounts are tied to real identities and the company is pretty aggressive about removing duplicate accounts. It should be possible to ID most of the people in that chat and report them to the administration.
Might be interesting as an option for the @lru_cache decorator to be able to specify a function to call before handing a cached value to the user. Then you could just do

@lru_cache(post=deepcopy, ...)

to have a new (copied) instance in cases where that's required. Or do whatever else you needed. Maybe you happen to know some details about the returnee that would let you get away with copying less and could call my_copy instead.

Something something power of function composition.
I would consider her as one of my heroes.

Having said that, probably she has not faced a genuinely strong attempt at malignment yet, like some people tried to pull off on Stallman (“he is a defender of Epstein and child rapists”) few months ago. I hope she has a support system to fall back on when that happens.
