> Robustness is something that seems to be very hard to measure, communicate and sell until something bad happens.

This is endemic to business and is especially widespread in contemporary American-style business, and the general case seems to be a failure in pricing all kinds of tail risk. I suspect a key challenge in this space is the unsolved principal agent problem.

I think the principal agent problem is rampant because pricing information is extremely lossy information compression; only the grossest outcomes are recorded in the market. Those who exploit the principal agent problem rely upon externalities to succeed, and those externalities are not timely or fine-grained reflected in the compressed/price information.

Reputation systems lossily add the missing information back into the market as a side-channel. But what externalities to record is a whole other can of worms.
Just this evening some Italian scientist announced on his twitter account that the number of new positive cases does not correspond to the number of new tests carried out and announced for that day, because those tests could have actually been made 2 or 3 days before or something like that.

Which, presumably, instantly invalidated all the charts and data-modelling based on the "number of new positive cases" / "total number of tests made" (with a lower value being seen as better).

But the Region of Sicily (or its official twitter account, anyway) replied that in their case the number of new positive cases and the total number of tests made are indeed correlated, which of course means that everything is a mess in terms of data coming in and its significance.

Later edit: For those who know Italian this is the tweet [1] I was writing about, and it looks like I was remembering wrong, the guy is not a scientist per se, more like a "data scientist", he seems to be working at a company very similar to fivethirtyeight (but presumably focused on the Italian market).

Would it? The basics of the language are at least easy, you might have trouble when python drops into it's ffi. Same holds in the reverse; you can't easily do elixir ffi in python.

FFI aside, I don't see a good way of implementing Kernel.spawn/1, Process.monitor/1, etc. in python, without rebuilding the entire erlang VM from scratch.

Congrats on your launch! The site looks great—and it strikes a chord with me, because I'm working on an art marketplace as well (albeit for prints, not originals). Given we have adjacent, not competitive platforms, let me know if you'd ever like to do some co-marketing! Our product is www.vsual.co

A few things I noticed when looking at your site:
- I like the detail views you have on your pieces, but a the higher resolution, you may want to consider a watermark—and it's possible it will help with artist trust, as well.
- The "Apply as an Artist" link is kind of buried. It took me a while to find it. Might be worth moving that up, if getting more artists on board is a primary goal?
- As a buyer, I'm still interested in the total price, and it's a little hard to comparison shop when both the base price and period for works are different
- I actually really like the "message artist" functionality. That's a great touch! I'm sure artists appreciate it too

The TL;DR on TF-IDF: Applied Machine Learning
I'm not really sure your query is what it was built for. That's more of a google search than a community idea.
It's a fair question. The answer is that systems like this - that are real in their offering and not a pipe dream - are not promoting to replace traditional databases. Blockchain is a terrible term with tons of baggage so let me describe what I mean in more detail.

These solutions in my mind are better described as distributed systems that allow independent verification and audit of data and transactions from within the system itself.

This is useful when the data being shared involved spans multiple entities in terms of responsibility, ownership, value, and other impacts. Rather than having to rely on other mechanisms of verification the system itself is able to provide that verifiability at scale.

Essentially you're using a technology layer, which is a collection of existing concepts put together in a somewhat novel use, to disintermediate more expensive verification solutions.

I think it makes a lot of sense if you examine the value chain of securities lending (from creation of the instrument, custody, to lending, custody transfer, and finally audit and compliance).
It's an intriguing concept, price aside. I can see people paying for a space where they just can't hear the kids yelling and screaming.

I guess I'm just wondering how it would work in the northeast, when you've got 0°F days and 98°F days. I get that it has an AC/heat pump (for $3,000 extra), but the fact that every morning you're going to need to heat/cool the thing from scratch feels like it could get real expensive real quick. Does this thing have decent insulation? (Judging from how thin the walls look from the photos, it seems no.) Are the window/door double-paned?

I suppose this is really intended for more moderate climates, no?
Cool but have to do math in my head while reading the page initially, can you add total price.

In the 9 days since we still have models that are all over the place. Nate Silver covers the difficulty in predictive modeling of pandemics in his book "The Signal and the Noise" and in the years since it was written not much has changes to they're basically rehashing the points he made then.

Gate keeping is a double edged, and somewhat blunt, sword.

First, some Maverick is going to ignore what everyone says and implement crypto for serious applications. Like yours truly.

Second, I've seen it go a bit too far when I implemented Argon2i: there was a discrepancy between the specs and the reference implementations, and the authors haven't corrected the specs. I figured this was because not enough independent implementers bugged them about that. (Now, 3 years later, the specs still aren't fixed, so maybe the authors are really really busy. At least but the issue is still open: https://github.com/P-H-C/phc-winner-argon2/issues/183 )

Actually, it seems to me that more or less, that is exactly how some of the network based contact tracing models work:

"Therefore, characteristics of mixing networks—and how these deviate from the random-mixing norm—have become important applied concerns that may enhance the understanding and prediction of epidemic patterns and intervention measures." [1]

And as a follow-on, that is why there is so much discussion about using mobile apps for contact tracing - it builds the network for you, passively.

There was also something odd about `Box<T>` automatically dereferencing, as well as `&&T`, but not `&Box<T>`.

I like to go to the local art institute's sale for students.

I've found some amazing things there for ~$50 to $100.

Personally I would find it hard to spend a great deal more than that based on a web view. The difference between 'meh' for me and 'amazing' is very subtle / really shines when you see it in person.

Still a great idea.
Ok. Replace the CCP and China in my comment with the other countries you mentioned. You get the exact same mechanism of degradation of your universities, you're just still trying to feel better about it by pointing out that your charity is towards other, poorer, less authoritarian countries than China.

The thing policymakers do not understand about globalism is that it takes advantage of existing institutions, necrotizing them in the process, by infecting them with incentives they were never designed to handle. Where once you had a closed system that was working well, you now have a system exposed to graft, grift, and entropy from agents without accountability for how they take advantage of it. So, these agents can find ways to leverage an institutions' own interests against the interests of the people it was originally designed to serve. Much the same way European imperialists could exploit the internal fissures of colonized peoples. Sand in the gears of a clock.

This is what happened to manufacturing in the United States. Once the American governance class became culturally and financially loyal to Wall Street, there was nothing stopping developing nations & capital from convincing them to move the entire American industrial base abroad in pursuit of higher returns, no matter the irreversible social damage it caused at home.

The Charity Consolation Prize is exactly what those businessmen and policymakers pat themselves on the back with too when they look at the destruction wrought on the American middle class ("Look at home many Indian people we've lifted out of poverty!"). Which would be great! If they were the leaders of India!

So you are right that it's driven by greed now, but it's not just "something that happens." The university system in the U.S. and Australia did not just wake up one day and decide to become addicted to Chinese money. Someone gave them a needle full of the stuff to try. It's an exploit in the system that can be closed. It's a choice.
They already tried that with TamTam (https://tamtam.chat/) which is also owned by Mail.ru Group. I don't know anyone who uses it though and ICQ had a huge userbase in early 2000's in Russia, so maybe that's the reason?
Having maintained an open source project for a while I relate to a lot of the problems brought up here.

It's really really hard to create a contribution system that works well when there is a large set of users, a large set of contributors, _and_ a tricky design space. It's tempting to become authoritarian, especially when the design space is complex and you've thought about it longer than anyone else. Inclusion is a shit ton of work, and a lot of it feels non-technical and boring to most people.

It's tempting to throw away compatibility and ask users to just deal with it. No project is perfect at this, but infrastructure stuff has a much higher bar for this than most other projects. That makes everything else that much harder.

Most tech culture undervalues management a lot, especially in open source. But open source should be valuing it more, because the problems are so much harder than in a small co-located one-company team -- communication is lower bandwidth and higher stakes, there's no way to manage other people's schedules, there's differing goals and incentives, and on and on.

So they apparenrly survived for 20+ years without hunting

”start = time.time(): doesnt need any explanation”

So, is that evaluated when that statement is run, when the value is first read (lazy evaluation, as in Haskell), or every time ‘start’ gets read. For example, Scala has both

val start = time.time()

(evaluates it once, immediately),

lazy val start = time.time()

(evaluates it once, at first use), and

def start = time.time()

(creates a parameterless function that evaluates time.time() every time it is called)
Strangely, Google never released maps of this important data, which shows which counties are heeding "stay at home orders," So, I scraped the data from the PDF's they released, and mapped it.

In times of great uncertainty or upheaval, markets fluctuate up and down pretty wildly.

Everybody realizes it should adjust to some new value to reflect the new reality. But nobody knows what that value is. So nobody is sure if the market has adjusted too far or not enough.

So any time any new information comes in, people grasp at straws trying to make sense of the situation (and/or decide they have to act despite very limited information), and the market goes up and down.

It doesn't just move smoothly in one direction and then gradually come to a stop once it finally reaches the new "correct"(-ish) value. It jerks back and forth as it gets there. So even when down is the inevitable direction, it's going to have a few ups mixed in.
When I left last August, we had around 600 in engineering, around 900 in product and engineering.

Engineering was mostly based in SF but with satellite offices in London and Hamburg. It looks like they were expanding in a large way into a Toronto office too.

Infrastructure was around a fifth of that total but included verticals like search and machine learning infrastructure.

I think optimal strategy was to be overweight to start, and to have a good mental plan to persevere.

I really liked him, not knocking him, but if they were all the same body fat % to start I'm not sure he'd have been the winner. The girl who got 2nd was absolutely not prepared to quit.

I've been working on a large front-end project using Ant and almost used/customized every component it has to offer. One of the best frameworks out there. Everything works great out of the box, and the framework is very well though and designed.

It has components that the rest of the frameworks, including Material UI simply lacks, including a very comprehensive Table component, and a Form component with validation and everything.

The selectors approach is clever, given that it works without a `map_err` closure but still supports borrows through the `Into` conversion. Unfortunately, all the libraries before yours have ruined the chances of me using anything outside of libstd as far as error-handling is concerned ( https://news.ycombinator.com/item?id=22820661 ).
I didn't say anything about gatekeeping. It's okay to make mistakes, that's one of the best way to learn.

I said if one isn't comfortable with the math, maybe don't try to roll one's own crypto and advertise or use it as production-grade crypto.
It’s a lot easier to implement an immutable language in a mutable one than vice versa, or so I’d assume, never having tried.

But yeah, I’d assume you’d have to build the VM first. A lot of work.
Analytics: From Google to Goat
I haven't read OP yet but I don't see what is the issue here. I honestly think what you see as issues are perhaps because of your lack of exposure to a wider range of languages?

CF clearly is a prefix for a library. I'll take an educated guess it means Core Foundation? Pretty common pattern of naming things, with +/- to be certain. And once you've seen it, it is just there, and you know precisely what it means. So 10 minutes of your life to learn what CFxxx() means.

Let. I like lets. Some don't. Surely we can coexist?

x..y is also not unique to Swift. It has a nice mathematical look to it, is more concise.

Btw, is that 'range' in Python inclusive or exclusive? It isn't clear from the notation. Must I read the language spec to figure that out? .. /g
The entire reason teams exist as a concept is to improve management and coordination logistics. A standup is a daily meeting that every team member has to attend, and in order for it to be productive it shouldn't just be robotic status updates; each member should actually be ingesting and thinking about everything that's brought up. Making sure it can be run smoothly should actually be considered an important factor, and if it's not it does call into question the objectives of the team lead or project manager. Of course, there are other factors as well, as you suggested, and there are indeed cases where a standup of 15+ people can make sense. Even in those cases, though, it is a result of pure incompetence to let the standup run for 45+ minutes even a single time outside of perhaps a major disaster.

As a supporting datapoint, in the entire company I work at, there isn't a single standup with that many people.
To add, never rely on products that require you to trust the company respects your privacy. E.g. Telegram lacks ubiquitous end-to-end encryption (E2EE) so even if the company chooses not to abuse the insane amounts of valuable data, nation state hackers are most interested in hacking these centralized troves of data. Not even opt-in E2EE is good because that leaks metadata about desire to use proper encryption. Always use apps that are E2EE by default (e.g. Signal) to ensure you're not leaking content or metadata about wanting to keep discussion hidden.
Hey, it really wasn't that complicated! Tbh the stubborn choice to stick with youtube as the host source was by far the hardest part as it limited what I could do hugely (e.g. you can't pause youtube videos without an annoying popover...)but it means someone could just use youtube, a few image assets and update the JSON files to do another dvd menu.
If you were using MP4s directly it'd be so much easier...

-------

What I knew:

1. DVD's break the video into these .VOB files within the VIDEO_TS directory

2. the menus, their transitions and their static content seem to be in the VIDEO_TS.VOB file. In the case of Shrek this was a 26 minute video which contained the menus in three different languages

3. the data relating to the menu is contained within a corresponding .IFO (or maybe .BUP, I forget) file which were overall very basic from what I could see

4. Ultimately most DVDs could be easily charted into a flow chart of menus, transitions(videos that cant be skipped) and videos. So a JSON file that defines an overlay for a video wrapper and controls its actions could largely mimic the process.

5. I never actually investigated how subtitles and audio are handled but I assume it's not too complex

-------

What I done:

- Converted VIDEO_TS.VOB to mp4 with ffmpeg: this could be done way better I'm sure. I know nothing about VOB but ffmpeg was definitely (but inconsistently) picking up the endpoints of videos within the container so I had to do a stream record

- The tools I could find for reading the .IFO data file were very very old and for windows, struggled on my computer via Wine, I think theoretically you could generate most the data straight from these files but it was faster to just do it manually, I mocked up what the highlight icons look like (the ones for scene select were way too hard though)

- I couldn't find a way to even view the styles for highlights over selected buttons so I just took the two most generic ones and used them where I could

- Included the functionality of audio/subtitles via local storage, I assume this could easily be relayed into the video component if needed too

- Tried to keep the Shrek specifics separate from the JS but ultimately cut a few corners, should be easy to fix

-------

As far as motive, I was always just a bit curious as to how some menus worked. Discovering they're all just always playing a video file in the background was one of those "oh... I guess that was really obvious actually, why was I assuming something more complex??" moments.
One thing I've always been curious about with art in this price range ($500-5000) is the resale value. Say your tastes change and you'd like to get rid of one of these after a few years, how painful is it to sell? What are your chances of getting 50% of the purchase price? 90%? 150%?
