As a semi-pro writer, and on some of my longer comments, I've typically written something out, taken the last idea that came out as a result of that writing process, and pasted it to the top/front of the piece because that's the idea with the most time, effort and value I can add. Leading with that rewards the reader with the value up front, and then they read on for more, which includes my initial reaction and analogies that produced it.

Remember that most people who write are still sounding out ideas when they write, so the final paragraph or final chapter of a monograph is where to start with most things. Then I read them in reverse order.

If it's professionally edited, you can read the first few parts because the editor will have uncovered any buried ledes and popped them up into the front matter. In journalistic writing, the opinion ("context") they were trying to freight the piece with is at the end.
> Something has to do the caring—that's the ego.

This is the narrative that we are told to believe, but ask people who did "meditate the ego away". They will tell you that productivity and all the other things in life still just happen, only "you" (whatever that is anyway) do not care so much about them any longer. It is not a paradox. The "ego" itself is a paradox.
Back when I was a TA if a student had come to me with the problem you are describing and the compensatory technique you are using I'd tell them they might have mild to moderate dyslexia.

If you're a university student you probably have access to a student support service that can assess you and advise you if that is the case. In the mean-time some people find using the [1] OpenDylsexic typeface helps and coloured overlays over text can be effective for some (Literally stick coloured acetate over what you're reading or change the font and background colours if on a screen). Other than that using various [2] notetaking methods will help with with both reading and retaining the knowledge. You're kind of already doing that with the slides BUT handwritten notes are generally more effective than notetaking on a computer.

Upwork is a shitty and unethical company. Their website sucks and app doubly so. They make a lot money but have the worst product.

So next time, any one on HN thinks about writing yet another todo app, think about disrupting freelancing industry and upwork. It won't be cool and won't make HN top page most likely but it will most likely be a product and monitory success.
I assume this could be done with one surrogate per teacher rather than per student and would be almost as effective.
Hm what unused better software did Djikstra write?

Maybe Knuth could have used Fortran and not Pascal, but that doesn’t solve the literate programming problem ... he would still want something like WEB.

Seems like Fortran is more maintained today than Pascal, but Knuth couldn’t have known that. The community yak shave to translate the code arose out of other forces in the industry.
Depends on the system. In EU, these are often salaried positions as well.
I’ve always wondered why I didn’t see people at my employer doing this “change jobs every year for huge gains” thing, but if the huge gains are $180k TC I guess that’s why. FB probably pays the interns more than that.
I think it highlights, for better or for worse, the cultural difference between the US and the EU. Take for example the UK that went into lockdown after lockdown, the reason it hasn't been done in the US is that it would be politically untenable. If a politician in the US tried anything remotely like that, they would be burned alive by the opposition and the media.
The first bit I'm not sure about: it may be on a chain or in a content-addressed store like IPFS.

The second bit is what zkSNARKs and shielded transactions solve.
The IRC protocol is for the bot API only. The chat on the website uses a custom protocol, and the IRC daemon has always been a custom implementation with weird quirks.
This has also been my impression. I think the paradox is roughly this:

- People who understand driving the most meaningful outcome may not be egotistic enough to want to drive it (they're content in life, their self-worth is unlinked to their outcomes)

- People who are willing to sacrifice lifestyle to drive meaningful outcomes also care about being right and are easily blinded by their ego when they're wrong

And the most depressing of all:

- Commanding the resources to drive meaningful outcomes too often goes hand-in-hand with being entrenched in some kind of a system that's too inefficient/bureaucratic/political to actually empower anyone to drive meaningful outcomes.

Another crutch:

- Driving meaningful outcomes can go hand-in-hand with absolute and utter obsession for navigating whatever is needed to drive it. Personally I understand it as the doing/reflecting dichotomy. Doing the doing leaves little room for reflecting and vice versa.
Author here. Yeah, I am also still a trainee or an 'early career research' or a 'junior researcher.' These terms are...weird.

Best advice I've heard from people who have been doing backcountry for decades: Don't. Hunt. Powder. Don't storm chase. What might make sense for in-bounds at a resort doesn't make sense in the uncontrolled backcountry.

The YouTube videos and magazine shots make it look like that's what it's all about. Foot after foot of fresh snow and face shots. But fresh snow, unconsolidated, after a storm is deadly. Especially early season. The people I know who have been doing it for years prefer late season spring skiing in the backcountry, even if it's icey and crusty.
That may be the case for cars from dealer/manufacturer lease/hire-purchase schemes, but for the big corporate leasing companies (e.g. Arval, Leaseplan, et al), the cars usually get picked up at the end of the lease and dropped off at the nearest BCA facility and auctioned off ASAP.

(Which is amusingly the cheapest way to buy your car at the end of lease... just ask the pick up driver where he's taking it...)
That's your anecdata, why should we treat it as representative? I was delivering food throughout the pandemic and not one person I handed the food to wore a mask (even when all deliveries were supposed to be no contact)

We didn't have any vaccines or effective treatments during the 3 month soft lockdown, you think it would be better to have congregations every Sunday to increase that spread? Or is God going to send us to hell for not attending mass during a plague?

It's so frustrating because the "lockdown" was doomed from the moment it wasn't enforced. Like you don't get a "threatening letter" if you posess a gram of cannabis. Our criminal justice system comes down hard except when it's people who don't care about public health. So yeah, we wasted like 3 months because most Americans prefer eating indoors at Applebee's to keeping disabled or elderly people around (and everyone else healthy). COVID has really shown me how much eugenics is still alive in the US that people can do a mental calculus about who is "expendable"
That's my point. It's not popular because it's not economically viable in many cases. So heating buildings is another thing that Bitcoin is supposed to improve, except it really doesn't.
Is there any precedent for using existing rootstock for grafting at a large scale on publicly-owned trees? E.g. I know you can also graft che trees onto osage orange, but I've never seen it done in a large public park with lots of osage orange trees, only by rare fruit hobbyists in their backyards.
Thanks for letting me know! Gonna check it.

Not really, e.g. the logic to send messages is different, does WhatsApp have sealed senders?

> Why should I trust Moxie more than Facebook?

The point of E2EE is that you don't, especially since you can update on your own schedule. There is some trust somewhere ("this version has been released for 3 months, nobody complained, seems fine, should be fine"), but you don't have to trust Moxie.
S&P 500 doubled in 5 years

Bitcoin is 41 times higher in the same time period

Nasdaq is down 6% in a week

Bitcoin is up 4% in the last year, it was 40,254 on the 9th Jan 2020, and currently 41,766. Its lowest point in Dec 2019 was 6,540.05. Dec 2020 was 17,619.53. Dec 2021 was 42,874.62.

None of that really tells you anything about the relative worth or the direction.
Yes, I agree that these costs all exist. What were those same costs where countries kept open measures, on top of the resulting deaths? I honestly can't even find that information, but it seems that it's not being factored in most calculations. It's always "open is bad because increased deaths/infections, strict is bad for the economy". I gather from the world data that the open measures have a comparable economic and human cost, on top of and also from the increased infection rate.

I think your final point is the sad truth, but not because of not having the technology: people, especially in the US, are ultra individualistic. If people thought of the folks around them as real humans with lives that would be devastated by such a disease, we wouldn't have a need for any government measures. But people decided not to wear masks. People decided not to quarantine properly. People decided to write articles such as this, condemning the few institutions that (for whatever reason) are doing even the bare minimum. Appreciate your thoughts.
I see where you're coming from, but, as a first grade teacher, I can say that remote learning doesn't prioritize teachers' needs either. Rather, it reflects the minimal investment a school or district could possibly make. For these past two years, we could have invested in PPE, filtration, and reducing class sizes. We could have prioritized approving vaccines for children. Instead, we're now expecting adults and children to sacrifice their safety in order to go to schools that are roughly the same as they were in 2019.
the problem is that HTTP2 mostly does not bring the expected advantages that connection multiplexing promised, as HTTP/1.1 connection multiplexing over multiple tcp sockets are in many cases better performance wise. Only HTTP/3 with QUIC addresses this, so I have mixed feelings about HTTP/2.
I have my doubts. It seems like that would be even more likely to drift than inline comments.
The data is updated daily, so new/removed movies shouldn't be a problem.
Upwork is a garbage platform, and if this situation really shocks you then you don't know anything about the company or the platform. My advice is to stay far away from Upwork. Fiverr is nearly as bad.
Except that ZKPs had already seen real-world use before Satoshi's whitepaper was circulated; in fact, there was an already-defunct startup that was selling ZKP-driven authentication tech. Secure multiparty computation is even more advanced than ZKPs, was already deployed in several real-world applications prior to Bitcoin, and has probably driven more research on ZKPs (as a building block in MPC protocols) than anything in the blockchain space thus far. As for how widely productionized the technology is, while I am not sure how you define "non-trivial" ZKPs, U2F was almost certainly a more widely used ZKP application than any blockchain tech, and there are plenty more real-world ZKP applications having nothing to do with blockchains that we could list.

David Chaum dreamed about a world where electronic payments could be anonymous and secure, but the demand was not there and his startup never took off. "Blockchain" sucked most of the oxygen out of the room when it comes to further work on ecash, which is unfortunate given that even the most technically complex ecash proposals were overwhelmingly more efficient than any blockchain-based payment tech ever could be. For what it's worth, the most recent ecash proposals also advanced the research on NIZKs and ZKPs more generally (it is actually hard to avoid some kind of NIZK in a system that supports offline payments) and had ecash been deployed more widely we probably would have seen at least as much research and productionization activity as we see in the blockchain space.

On the other hand, blockchain research has struggled with a foundational question that does not present a problem for any of the technology I mentioned above: how to properly define security. Especially in the permissionless setting the effort on defining security has been unconvincing so far, requiring a very stretched approach to formalizing computational resources that is hard to actually map onto a real-world application. Satoshi did not start with a well-defined problem he was trying to solve with Bitcoin, and such an approach -- clearly identifying the problem you are actually trying to solve and verifying that the definition is logically consistent and realistic -- is exceedingly rare in the blockchain space, while in mainstream cryptography research it is a de facto requirement. So while blockchain tech has not experienced a spectacular failure due to some theoretical shortcomings, the theory itself is not well developed compared to the theory of cryptography in general (including ecash, which can be rigorously defined and proposed systems can be proved to satisfy the definition).
When I joined my manager had a few onboarding tasks, I did all of those, and started protoyping my first PR. It was actually a pretty meaty open-ended project and in retrospect it was sort of high-effort, low-reward. I iterated on that several times, wrote proposals, solicited feedback, but ultimately nobody really gives a shit about it, so it hasn't gotten shut down or moved forward.

At this point I've kind of accepted the project is dead but my manager is gone. I've put together a few small PRs but they're similarly just in review hell.
Thx for explaining why I see a blank page, I have the same problem.
I wouldn't say it cuts down on smell, unfortunately. In fact, it has the potential to make it worse, since the waste is gathered in a bin for longer periods of time (as opposed to flushable litter in a normal box).

There is a carbon filter that sits on one end of the tray to help minimize scent, but it's not very effective in my experience. I'm currently experimenting with putting various nicely-scented objects in that tray, in front of the filter (like those little scent blocks you can hang on the side of your toilet bowl, for example).

The scent will also largely depend on the cat's digestive system. My cats tend to not have very smelly or soft feces so it's not bad at all, but if one of them gets diarrhea you bet I'm emptying that litter bin right away. Likewise, if a guest is coming over I'd probably suggest emptying the litter bin beforehand just in case.

I know you already know of better litter and baking soda tricks, but there is a powder you can purchase and sprinkle into litter, which gives off a fresh scent. I found using it also helps, as does sprinkling some of it into the bottom of the litter tray itself (into the litter waste bin). I don't have the name of it on hand, but I think there are a few brands out there that are pretty common.

Edit: the _majority_ of the time there is no smell I can easily detect until I open the tray to remove the garbage. But as someone else mentioned, no smell to a cat person may not be a reliable gauge.

The service provider sure does. They can just decide to not let you use the service.
Who is your ideal user? Do you think this person frequents ProductHunt? That's your answer.

My experience is that the main users of PH are those launching a product.

I'll also add: after my PH launch, I experienced a lot of email spam from "growth hacker" types. I suspect they scrape PH. I tried to take down our post (because the spam was overwhelming), but PH refused.

That's very amusing an inspiring--makes me want to write an retro/8-bit game too.

Wonder what the story is on the sheep: did I hear "Just call me baaaa-man"?
For me, it is the opposite. I feel much more productive when writing code, to the point where my idea is "when I am not coding, I am not working". I don't even have a pen and paper at work. I have a phone with a stylus that I use as a substitute from time to time, and I sometimes take notes on text files, but 99% of my thinking is done while coding.

Code is what keeps me down to earth. It may seem like an unnecessary detail to think about how to pass a variable when you are barely familiar with the subject, but if you can't get something that simple right, chances are that your are going it the wrong direction and when time will come to do the implementation, you will be in a world of pain. Of course, a lot of that early code ends up being thrown away and reworked, but in the early phases, it is rarely a problem.

It probably has to do with a top-down vs bottom-up approach. I am much more comfortable working bottom-up, thinking first about the details and how they fit the big picture, rather than to top-down approach, where you think of the big picture and work up the details later. I think that both approach will eventually lead you to the same destination, so choose the one you are most confortable with.

Also, context matter. I do mostly low-ish level programming (mostly C++), I don't know about coq, but it seems to be more maths than technical engineering, so maybe a different mindset is required.

But out of date in which way? It could be anything from some extra cases to literally the opposite of what the comment says to the code has changed so much it’s not even clear what the comment refers to anymore.

This is really cool! At the start of the pandemic, I researched UVC light as a mechanism to kill the virus. I do want to point out a minor point:

>However, the widespread use of germicidal ultraviolet light in public settings has been very limited because conventional UVC light sources are a human health hazard, being both carcinogenic and cataractogenic

conventional UVC is generated by mercury light bulbs and are carcinogenic and cataractogenic

BUT about 10 years ago, it became practical to use frequency doubling in LEDs to generate light really close to the mercury light - the LEDs are not carcinogenic and cataractogenic. When you read about UVC effects, you should check what type of light source they are using (mercury vs LED)

Also, it is the advancements in silicon manufacturing that has made it cheaper to make new and different LEDs - such as these "far-UVCs". It is pretty legit!

There is "a lot" of research demonstrating effectiveness of "conventional UVC", but not a lot on "far-UVC". One of the limitations on both is the shadow effect... got to go. I'll elaborate if there is interest
The bank (or transfer provider) eats the amount. And yes, it gets quite some abuse. It's especially abused against gas and electric providers when they've gone bankrupt since people tend to have paid those companies tens of thousands over many years, and when the provider has gone bankrupt it's unlikely they'll provide any evidence to dispute any chargeback.
> If a student's goal is to build something that people actually want to use, they are much better served by taking an industry position in a product group.

Agreed, I should have phrased that better. Fundamentally, the focus should be on 'generating new knowledge,' right?

> From my perspective, the obsession with publishing is just another version of the same problem.

Yes. :(
OTOH it might be easier to take a urine sample from a toilet trained cat. For litter trained cats you need to use special non absorbent litter or leave the cat at the vet so that they collect the sample themselves.

It is the expectation they create, by taking care of the drudgery of having customers Upwork puts itself in an excellent position to reap a chunk of the turnover of the freelancers they put to work, but it also puts the onus on them to ensure that customers pay their invoices and do so promptly and properly.

Note that there is absolutely no dispute at all about the work being performed or the quality of the work, and if there was they might have a leg to stand on, even if that came to light this long after the fact (though, again, that would point to some process errors at Upwork).

The responsibility of payment processing and due diligence with respect to which customers they do business with and how they arrange the various payment options lies entirely with Upwork. In this case Upwork is the seller. They buy the product from someone else and that's two separate relationships, Upwork now suddenly wants to pretend that they weren't part of the transaction after all and that the relationship ran directly from buyer to their supplier but that isn't the case.
In my experience, Teams has been a terrible alternative to most every option out there, including IRC. The entire UI/UX seems like an afterthought at best.
The Nvidea Shield Android TV box was an interesting case in this space. It is much more expensive than a Roku or FireTV box, but has some premium features.

Originally, there weren't ads. But because Google controls Android TV, intrusive ads started appearing. So you paid for a premium product, but ended up with a shitty experience.
