My understanding of the MAX issues is that the issues were not really shortcuts, though they might look that way in hindsight (because every mistake looks that way in hindsight).

From my non-aviation perspective, it looks like they basically pieced together a bunch of complex systems, with each team making a number of (different) assumptions about each system. The systems themselves were influenced by FAA requirements to maintain the old certificate, which meant that certain desirable changes were impossible, so workarounds were devised. The problems were due to misunderstandings about how the systems would work when assembled, and these issues were not discovered and/or communicated. It really seems like a systems engineering problem, aggravated by a number of external influences (including business reasons and certification).
UCL is another good choice for this area. I did some research in this area back in undergrad. There was a workshop called NAMPI (neural abstract machine program intelligence) on this subfield so I'd recommend going through the accepted papers for it and seeing where all the faculty come from.

Also general advice, after finding a few papers you like go through the papers they cite that are relevant to the subfield and also papers that cite them. That's one of the best ways of finding other related research that interests you.
So why facebook but not movies and TV over the air or streamed via other platforms? What, because it comes from studios and other sanctioned organs? Are they above propaganda and above having agendas?

I’m not saying FB is not culpable, but I’m saying if they are, then so are others.

That isn't a bad thing. We are constantly influenced by design and society. It's going to happen. And in Facebook's case, with respect to Rush: "If you choose not to decide, you still have made a choice". Choosing not to build a user experience that disarms unnecessary conflict, or that can limit disinformation, is a clear choice.

The idea of designing human interaction and government policy with the knowledge of how humans react is not shocking or new. Heck, the "Pandemic Playbook" from the CDC continuously references group behavior when discussing how to communicate facts to the public. For example: If you tell people to stay home on day 1, the public may doubt or tune out your advice. So what do you do on days 1-3 so that on Day 4, government advice is heeded? Get private companies on board, ramp up voluntary advice for some time, before letting the big news fall.

If you'd like to learn more, check out Nudge by Cass Sunstein [1]. And another book by the same man, specifically covering the ethics of governments using the technique. [2]

> but this kind of thing sets a high standard for reproducibility of published results.

I think making the code available is good, but I think we should be careful how we use the term "reproducibility". Pulling your repo and running it had better give the same results, but it's not the same sort of thing as building my own experimental setup according to a paper's specification. The latter gives more room for variability such that successful replication speaks more strongly to the robustness of the result, and also puts human brain power next to each step of the process in a way where weirdness might be noticed.

Replication should probably involve reimplementation, if it's to carry its traditional weight. In the event that we fail to replicate, though, having the source code for both versions is likely to be hugely informative.
Maintaining cash currency will cost the US roughly $877M[0], out of the Federal Government’s $4.7T budget, or 0.01% of the Federal budget.

So in your view, sacrificing people’s privacy by giving this sensitive data to Facebook and ceding the government’s distribution control for what amounts to minuscule savings is worth it? Just for scale, if you were operating a $100k budget, you’d be saving $10 while giving a private company immense control of the financial system.

How do you justify that?

Pleroma also is cleaner code-wise so there's that, more active dev and lightweight relative to mastadon.

Facebook launches CatchUp audio-only calling app that shows who can chat now

Was able to download and install app with US Apple ID and iPhone SE (2020) on iOS 13.5. After install, it asks for age confirmation on get started flow. If I try to sign-in, it asks for a phone number for verification. As far as I got so far. Splash screen shows 'Developed by NPE, a team at Facebook'.

'Facebook’s internal R&D group, NPE Team, has today launched a new app called CatchUp that makes it easier for friends and family in the U.S. to coordinate phone calls or set up group calls with up to 8 people. While there are a number of group chat apps available to users today, what makes CatchUp unique is that the calls it enables are audio-only, not video, and it flags when users are available. In addition, CatchUp won’t need a Facebook account to use the service — the app works with your phone’s contacts list.

'CatchUp does seem to take some inspiration from Houseparty, in that users in CatchUp can designate when they’re available to talk by setting their status in the app. This is similar to how Houseparty’s video chat app also lets you see who’s live, by sending out notifications when friends open the app and flagging them as “here” in the app’s interface.'

Original title was too long. It was:

I'm perfectly happy using Hugo + git hooks. It's easy as

1. Write a post in markdown

2. Commit and push

This sounds like complete bullsh*it.

Where does he bring up the subject of Facebook connecting people to the level of addiction? With the only goal of maximizing screen time (and dopamine) to sell more ads? It's not "connecting people", it's "addicting people".

It is as if a 3rd world foodbank for Africa was bragging that they feed the world so well that 90% of Africa is now overweight, but that's good because they continue to "feed people".
I think what happened here is a little different than how you describe. For me, it seems they had a hypothesis, found support for their hypothesis, then changed its definition for speculative motivations with tangible harm.
Engines might be an appropriate analogy to flywheels, but a funnel is a different thing entirely, as is your quote from David Ogilvy.

A funnel typically represents the customers' journey, with some amount of dropoff at each step along the way, e.g. discover the site --> sign up --> become active --> convert to paid. And although each step of a funnel leads to the next one, the last step of the funnel doesn't loop back around to feed into the first step, which means the funnel isn't a closed loop that feeds into itself.

A flywheel, on the other hand, is always a closed loop. And most commonly the steps on the flywheel are business strategies, advantages, and activities, rather than steps along a user journey, e.g. provide a wider selection of goods from sellers --> make buyers happier --> get more buyers --> attract more sellers --> repeat.

Just Google Image search a picture of a flywheel and a funnel and the difference should become immediately clear to you. And note that you can combine the two concepts. For example, in the flywheel, the arrow between attracting more sellers and getting a wider selection of goods could be represented as a funnel.

Finally, your David Ogilvy quote is neither a funnel nor a flywheel. It's just a list of three distinct benefits, all of which derive from him writing something, but none of which feed into the others (or at least he doesn't describe how they do.)

My observation of points at which even very smart people fall off the "math train" k-12:

- Fractions

- Factoring

So yeah, I'd say great care is warranted in teaching kids fractions. Screw that up and there's a good chance you've lost them for life.
It's a shame that WeakMap and WeakSet aren't enumerable. Ephemeron tables in Lua are enumerable, so creating a data structure that detects when an object is gone is possible. And because Lua supports finalizers, you can trigger an event the moment the object is garbage collected.[1][2]

[1] Lua also supports reviving objects. For example, if your finalizer leaks the object to the outside environment. Implementing this can be tricky, which is perhaps why JavaScript doesn't permit it. So many limitations in JavaScript exist because a particular feature would be too difficult to implement in existing implementations.

[2] Of course, because Lua supports finalizers it's possible to detect GC without using ephemeron tables. But if you can't control the target object's finalizer, then ephemeron tables are handy for doing this. And you can use your own finalizer on the ephemeron table value object to detect GC, though it'll trigger one or two GC cycles behind when the key was collected.

I remember seeing glasses-free 3D displays from sharp many years ago and thinking this would be everywhere within 2 years. The technology was used in some asian novelty pre-smartphone handsets and in one gameboy model but then disappeared. This was not light field technology like the Looking glass, so only one angle and one viewer could really enjoy it, but i assume the market will behave pretty similar this time: After the novelty wore off, nearly every single user i talked to preferred 2D displays if it had even slightly increased display clarity, brightness and resolution. Of course that insight sounds nearly trivial, but what really surprised me was the extreme degree of this preference: People were not even interested enough to make 3d Monitors a second mainstream option next to super retina 2d displays or whatever, but the whole market did not even come to existence outside very small niches. In a completely different context i was extremely surprised how many early "VR" experiences did not even mention they were just in 2D with head-tracking and no one except me seemed to find that odd or super annoying. It is as if no one really cares for 3D.

Are you seriously arguing that consumers can't spend $5 less on a shirt so that instead of having "BALR." it was made under less shitty conditions? Consumers have plenty money for t-shirts, they just choose to spend it on fashion statements instead of thinking about working conditions of people half a planet away.

There's plenty of choice. It's not about choice, it's about what's on your mind, and what you put on your mind. If you want to look cool, you put the working conditions concern off of your mind. If you want to make money, you put the division concern off of your mind.

The buck stops at every stop.

edit: did a quick google, first result on a plain white t-shirt that's fair trade is $25, first result on 'fashionable' plain white t-shirt (by balr or supreme) is $60...

You need to be more specific about what part you're having a problem with and what your goal is: to build a scraper you can sell or give away, to accumulate social media data for commercial purposes, or some research goal?

There's no generic solution, since every platform is different, and there's no one scraping library (or approach) to rule them all. Most efforts I've seen use BeautifulSoup to parse web pages and/or Selenium to automate browser actions, but I'm sure there are better alternatives. It is a frustrating space to work in as many/most tools are limited and the methods jealously guarded, much as most social media companies jealously guard the data they harvest.

You could probably learn a lot by leveraging existing tools and seeing what you can do on the analysis side. Twitter has a fairly well-specified API and if you are getting frustrated with the limits of that, there's twint. Facebook is the biggest 'pile' of data but they know it and when you look at the source a FB page you can see there's a lot of stuff that messes up your ability to parse that data, accidentally or deliberately. You might be better providing tooling for small but growing social media platforms that are not as big (and so less valuable/profitable to scrape) but also don't have the accumulated digital sediment that makes it difficult to do so.

> For example, did you know that in the postwar 1950's, the lack of polarization and divisiveness in American society was widely seen as a major problem, because it didn't provide enough voter choice between the two parties?

There was not a lack of polarization and divisiveness in American society.

The divides in American society and politics didn't map well to the two major political parties because there was a major political realignment in progress and the parties hadn't yet aligned with the divides in society.

The problem was the divide between the major parties not being sharp on the issues where there were, in fact, sharp, polarizing divides in society, preventing members of the public from effectuating their preferences on salient issues by voting.
Honestly, this does give me much more confidence in Facebook's internal governance, even if the platform often bows to media demands.

Much to the Chagrin of many on HN, Facebook is, and has been a fairly open platform to people of all convictions, backgrounds, and political stripes. Even if it has been unsteady handed at times. This, as well as their sorting algorithm may well be contributing to the collapse of institutional trust and cultural balkanization of the western world.

To a progressive liberal or political moderate who directly benefitted from the economic and technological booms we've experience over the last 30 years this is upsetting, because the global order (and its associated stability) from-which they've benefited, which brought us to where we are is disintegrating around us.

To me, hand-wringing about Facebook's relatively hands-off approach the political dialogues on their platform is just resentment about the loss of a prescribed cultural narrative and familiar cultural coalitions, the collapse of-which has given every stakeholder in their nation's future an opportunity to speak up for their own convictions and interests, in hopes that theirs will be the dominant narrative of the new political landscape.

I wish these dialogues and factional aggregations were occurring on a more federated network. But so far as centralized platforms go, I can't think of any company more fit (that's not a compliment, but a lament) than Facebook to host them.
> It's not because 'function powers' make sense, yhey are just iterated function application.

To be clear, I think you aren't saying "It's not because 'function powers' make sense" (which seems to apply that's not the reason it's done, and possibly that the reason isn't correct), but rather "It's not [an appalling notation], because 'function powers' make sense"—to me, that extra comma changes the meaning!
The aspect of the pandemic which impacts the USA most greatly is not the number of dead bodies, it is the loss of the perception of the USA as a global leader. Nobody thinks that Italy was key to handling the Ebola outbreak, so they did not lose their reputation over this. In fact everybody knows that Italy is a basket case led by craven criminals. But the USA was until recently viewed as the nation that could coordinate global action against pandemics. Now, everyone sees China as that nation. China is exporting masks and test kits and whatnot. USA is importing them. Officials with the German Marshall Fund, essentially a US propaganda outlet leftover from the Cold War, are going on the record discussing America's abdication of leadership.
From what I've seen of attempts to apply AI to the cyber security domain, a big impediment tends to be the lack of cohesion between the AI experts and the domain experts. There's often decades of work on the domain of study, and it's important that you use this information to inform your algorithms/ML models. I once worked with some ML researchers on trying to apply machine learning to some netflow data we had. These researchers were quite good at their field, but didn't know much about netflow data analysis. I remember them being all excited in a meeting because their models found some pattern in the data. It turns out they had discovered the difference between high ports and low ports...
The Chevy Volt is not a series hybrid. It can operate like one, in some modes, but GM actually found, especially for Gen 2, that a mixture of series and parallel is most efficient.

When the Volt runs out of battery, it's almost not noticeable apart from engine noise. The performance characteristics in hybrid mode are almost identical to EV mode in terms of torque/acceleration.

It's an engineering marvel. I love mine. Shame GM killed it.
