NiFi at first glance sometimes just looks like a glorified GUI for building out a data-delivery application. But NiFi doesn't just compile an application to be deployed on your network. Instead, the "power" of NiFi is that it allows an operations staff to perform the regular day-in-day-out task of monitoring, regulating and if needed modifying the delivery of data to an enterprise.

NiFi gives insight to your enterprise data streams in a way that allows "active" dataflow management. If a system is down, NiFi allows dataflow operations to make changes and deal with problems directly, right at tier 1 support.

It's often the case that an enterprise software developer has an ongoing role of ensuring the healthy state of the applications from their team. They don't just develop, they are frequently on call and must ensure that data is flowing properly. NiFi helps decouple those roles, so that the operations of dataflow can be actively managed by a dedicated support team that is more tightly integrated with the "mission" of their dataflow.

NiFi additionally offers some features that most programmers skip to help with the resiliency of the application. For example:

- the concept of "back pressure" is baked into NiFi. This helps ensure that downstreams systems don't get overrun by data, allowing NiFi to send upstream signals to slow or buffer the stream.

- data provenance, the ability to see where every piece of data in the system originated and was delivered (the pedigree of the data). Includes the ability to "replay" data as needed.

- dynamic routing, allowing a dataflow operator to actively manage a stream, splicing it, or stopping delivery to one source and delivering to another. Sources and Sinks can be temporarily stopped and queued data placed into another route. Representational forms can be changed (csv -> xml -> json, avro), and even schemas can be changed based on stream.

Anyone can write a shell script that uses curl to connect with a data source, piping to grep/sed/awk and sending to a database. NiFi is more about visualizing that dataflow, seeing it in real-time, and making adjustments to it as needed. It also helps answer the "what happens when things go wrong" question, the ability to back-off if under contention, or replay in case of failure.

Absolutely this. I've actually seen company founders get frustrated and upset at waking up and having Slack channels filled with complex debate that happened over night (even when they didn't need to read it). Not for any clearly articulated reason, just a vague feeling that people shouldn't do that.

Eventually it came out that a big part of it was:

1. Slow reading skills

2. Slow typing skills

With the result that some people felt they just couldn't keep up in such debates and would thus effectively lose by default. This was frustrating to the group of us that could read, write and type quickly because it was basically a mostly implied request that we stop being good at our jobs. The thing you say about workers "without a craft per se" just rings so true to me.

'Tend to' doesn't mean some conscious, directed effort. On large enough scale, this is generally the more probable direction, and that's about it. Its truly random by nature.

I was mostly frustrated that standard history makes it difficult to impossible to see where you ran commands, depending on how long ago it was. This struck me as something that should have existed in shells a long time ago.
I’m not sure why you’re confused about it being downvoted.

1) Whether or not it meets the (or someone’s preferred) definition of currency is wholly incidental to the answerer’s explanation, so even if correct, this is not the place to make the point.

2) Bizarre non-sequitur that equates finiteness of currency with zero sum utility which is a real stretch and easy to find counterexamples for (eg chore tokens).

For the cherry on top, it links Medium as a main source.

Is that a good enough justification to downvote?

You observed A ("welding doors shut"), then you observed B ("spread of the virus stopped"). I'm sure we can all agree that both the extent of 'A' and the extent of 'B' are not just unknown, but highly politicized and subject to a massive amount of misinformation.

Even with perfect information, it would be unscientific to infer that A caused B.
> it shouldn't take more than a couple hours
That's simply not true. It takes days for most banks to "settle their books", before which any money they've transferred hasn't really gone anywhere.

For day-to-day expenses for us common folk that's not really a concern but for big sums of money the recipient will want a little more certainty of the transaction having completed.

This can take weeks with some banks too.

I thought they insisted on calling it "Processing"?

I just write standard C++ or C code and it compiles fine. Hard to complain about that too much if I don't care to use the extra features. You can just access registers directly even if you use the Arduino IDE and configure things yourself if you want.

But yeah, I'd personally use visual studio code if I wasn't going to want to use the arduino libraries anyway. It's not a great editor. VS Code probably isn't that great either, but it's good enough for the little coding I do (I mostly design circuit boards that frequently use these little boards as brains).

Nifi is designed to handle the problems that crop up when two systems can't talk directly to each other. It puts a buffer between them to allow one process to keep sending data when the other isn't quite fast enough, it can do some basic transformation when the data isn't quite in the right format, etc.

However if you just need something to send messages then you're better off using a tool that does just that, you don't need the overhead of a system that can connect arbitrary applications that talk in incompatible protocols you just need a single protocol that allows your applications to send each other data.

In their docs Nifi calls itself a dataflow tool and calls dataflow a necessary evil. It's the band-aid you need when you've got a mismatch between the way data is generated and the way it is consumed. It would be insane to deliberately create such a mismatch just to use Nifi.

Sure, I can try. My thoughts on this actually come more from my experience in prediction market betting than my work, which is hard to apply at an individual level.

I think just properly accounting for wins and losses can be good at instilling a sense of humility; I'd recommend he calculate his track record if he hasn't already. I enjoyed the book Thinking in Bets by Annie Duke, which is about the psychology of developing some habits around making bets and the cognitive biases we have. A Random Walk Down Wall St. is also a classic that is good at instilling a sense of humility in you as an individual investor.

Another NiFi article was in Hacker News the other week with a fair few positive comments.

I left a comment with my thoughts and we pretty much agree with the exact same issues. Good to see I’m not the only one as seeing some organisations use it more and more to the extent insisting any data ingested in to systems need to go via nifi. Granted some of these are extremely large and disfunctional companies.

Yes, there are indeed other options. Like cash or a credit card.
The original sin was javascript itself, it was planned to be some variant of lisp but they decided to make it more palatable to the c syntax consumers and created a new language overnight. With lisp they could just use s-expressions instead of HTML. Maybe they just wanted to avoid the noise from the emacs guys ranting about how it could all have been achieved already in emacs or something like that.

I'll never forget getting our team of 90+ devs to move to prettier because of this argument and then having team members proceed to strong arm me to change the configs to things that they preferred six months after we made the move and we had adopted it across over 10 different repos.

It's very clear that this is potentially happening on a mass scale. There is nothing preventing it from happening, at least, and the hospitals are under serious financial pressure due to the inability to perform elective surgeries. You cannot invalidate what he's saying. It's easy to chalk that up as yet another conspiracy theory. But at the same time, why wouldn't a hospital take advantage of programs like this? There's very little threat of it coming back to bite them -- there's no enforcement.
Elon Musk defies stay-home order to reopen Tesla and asks to be arrested
Not yet, I'm advocating that our issues for new features should read like the eventual text in the release post.
One thing to remember is that people don’t have perfect vision either. As long as you are not out of shape or have sagging skin or gray hairs, people will not be able to clearly see any wrinkles or other textures in skin that would give away age.

In general I’ve seen a lot of people that look young for their age but when looking at their skin up close on their face, neck or hands it gives it away. Women are also at an obvious advantage through their use of makeup.

It's hard to say if that's entirely true. Sony did end up changing the system's color and making the controller bigger and bigger on subsequent iterations of the PlayStation, so apparently they came around on those ideas.

I just tried it. Went to the top seven sites for chicken tikka masala. Exited one for not loading, had to mute another tab with an annoying video, but got to the recipe in 6 of them in under two minutes. No popups (though I do have an ad blocker that may have prevented them).

>read the ingredients list, and click the 'next page' button to see the instructions to work out what you can tweak

That wasn't included. I was talking about scanning to verify there was an ingredient list. I pointed that out when I said:

>That just isn't a significant portion of time compared to how long I'll spend comparing different recipes to find a common theme to follow.

My understanding was that it happened more organically.

When I see a story at the top of a page, what I feel like I'm really seeing, most of the time, is an attempt by a nano-influencer, or really just an average person, to build a brand.

You could read 100 recipes from a person that included no details about themselves, then see their name on a blog and not even realize it was them.

But if the story is from the Pioneer Woman, and now you know a bit about her family, you might be more receptive to buying her cookbook, or signing up for her subscription newsletter, or watching her TV show.

Or, more realistically, in the other direction: you could sell Netflix on a show about you based on the number of recipes people view each month, that have your life story embedded in them.

So, over time, you end up with the current situation, as infinitely many people attempt to climb the ranks.
Elon Musk confirms Tesla is restarting its factory against local rules
Suppose we had data that we agreed was reliable showing that women software engineers who had read Damore's memo and Yonatan's post would overwhelmingly be unwilling to work with Damore and overwhelmingly be willing to work with Yonatan.

I'm not saying I have this data, but just hypothetically, suppose we did.

Would this at all influence your judgements (e.g. "deranged lunatic") of them? Why or why not?
Given this all-caps disclaimer, I wouldn't exactly be reassured that USDC would be worth anything in the event Coinbase went out of business:

"USDC IS NOT LEGAL TENDER. USDC IS A DIGITAL CURRENCY AND COINBASE HAS NO RIGHT TO USE ANY USDC YOU HOLD ON COINBASE. COINBASE IS NOT A DEPOSITORY INSTITUTION, AND YOUR USDC WALLET IS NOT A DEPOSIT ACCOUNT. YOUR USDC WALLET IS NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR THE SECURITIES INVESTOR PROTECTION CORPORATION (SIPC)."

similar ideas have been around for ages. for the most part they are unpopular because they have a number of severe usability issues: SSO sometimes uses multiple domains, password rotation requires either changing all passwords or memorizing a per-site generation, multiple entries per site requires memorizing a per-site key...
I love the specificity of these metrics and thresholds here. We're lacking that in WA, where the goalposts on reopening phases and variance by region remains vague and ever changing.
There was no `prototype` and `constructor` properties

o = new Object
o.foo = 'bar'
a = new Array
a[0] = 'baz'

But functions were constructors

function hello() { return this.name }
function Person(name) {
this.name = name
this.hello = hello
}
new Person('James')

Array push

var length = 0
a[length++] = 'foo'
a[length++] = 'bar'

Actually it was not bad for scripting language, no WAT:

new Object + new Array
//null is not a number

No `typeof` (so no `typeof null`), better `parseInt`

parseInt("foo")
//0

Much better start than ECMAScript 1

I really dislike this tone and trend in engineering projects - I understand cross-platform developer frustration as much as the next guy, but snide, cynical comments come across as unprofessional and naive. If it truly bothers you so much, don't support those platforms. Be the change you want to see.

This was one of the first "deterministic password managers", which has become a whole species of side-project password managers. The major practical win for deterministic password managers is that they're ostensibly stateless; you only need to synchronize some very basic configuration information to make them work consistently. In practice, not so much: passwords need to be changed, or revoked, or customized. You should just use "pass" (or 1Password if you want something professional).

An interesting thing about PwdHash is that they observed how you can use site-specific authentication behavior to break phishing, something that U2F/Webauthn tokens also accomplish.
I'm a Elon Musk fan in general but what about "duty of care" to his staff? Also what other laws can he (or anyone else) choose to violate?

1. Credit card fraud is an extremely small percentage of credit card activity. What you are proposing would likely not be.

2. Chargebacks are disputed, and as a storefront you can prove that you are not liable. Merchants can review the identifying documents of the cardholder for legitimacy and take other security steps, like using a chip-enabled card terminal, to further confirm the validity of the purchase. If they follow the process correctly, they are not liable for fraudulent purchases, the cardholder’s issuing bank is. Visa and MasterCard’s contracts generally put the burden of fraud reimbursement onto the bank.

Stocks don't purport to be currency though.

The question about gold is more fair. There have been times when actual gold coins were used as currency, and until 1971 the dollar was on a gold standard, meaning dollars gained at least some of their credibility from the fact they could be traded for a fixed amount of gold; i.e. paying in dollars was in effect paying in gold.

But now, no, gold's status as a "currency" is mostly from tradition. Still, it's relatively easy to use and its value is comparatively stable. And people can't just up and make a new one at any time.
Honestly, no offense, but that's a bit of a marketing fluffy non-answer to the problem that essentially says "it depends". A fair bit of what people want and need from an agent is trustworthy and reliable advice. Especially when it comes to the price and price-maximizing behavior. If one can't reliably find such an agent, then the problem will always persist. With that in mind, we need to get the agent's incentives such that they don't align with dodgy behavior on the part of the agent. They should not be aligning remotely to the agent getting paid with a non-optimal outcome for the buyer, which it currently does and so attracts dodgy individuals.

AFAIK MXN never claimed to be backed by USD, but Tether claimed that USDT are backed 1:1 by USD in a bank account. We now know that there aren't $6B in that account but people still choose to trade USDT near par with USD; I guess this is analogous to how the value of the USD didn't fall when it became no longer gold-backed.
So he's just trying to get away from a newborn baby?
>Was he wrong about that, or has something changed since then?

Nope he was right about that. What changed is blockstream took control of bitcoin development. They dont agree that on chain scaling is possible, and instead push proprietary alternatives to scale bitcoin where they can extract fees.
