Lol what are you on about.

You're mixing so many different things right now.
No -- since the early days of the "World-Wide Web", there were plenty of uses: colleges all hopped onto it, entertainment websites popped up, the first version of IMDB was mind-blowing, Yahoo! v1.0, James Berardinelli's movie reviews site... the list goes on and on.

Anyone saying it was just porn and drugs would just be disingenuous.

But Bitcoin, I'm not sure I've encountered a single "Pay with Bitcoin" option in any online shopping I've done. So where are the legit use cases hiding?
Yeah, they would both account for being off by a factor of 10-20. As would any of a dozen other simple mistakes or embellishments, in all likelihood. IIRC the Skeptic's Annotated Bible has a bunch of direct numerical self-inconsistencies if one needs proof that this sort of slipup is possible, which one shouldn't, because of course it is.
I think you're hand waving away all the complexity. You're right that distortion is pretty much waveshaping. But all the nuance, "warmth" and lovely non-linearities that make these pedals highly sought after is the really really hard part. It can't be simply solved with convolution.

The same pedal from this post has been pain stakingly circuit modeled by Cytomic[1] over the past few years and still isn't out of beta. Analog circuit modeling is a huge thing in DSP right now because it's the closest we have to proper 1:1 software clones of analog hardware. But it's incredibly time consuming.

I'm really excited by this use of WaveNet. It could drastically cut down the time to clone old costly to maintain hardware. But it will have some way to go before you can tweak the parameters in realtime. Or so I assume?

Based on a quick look at NiFi, SQL Server Integration Services (SSIS) seems similar. The configuration management tooling for SSIS is pretty good and it's amenable to version control better than, it sounds like, NiFi is. SSIS still suffers from the potential "gotchas" the top-level poster mentions.

Presumably they buy tether when it's under $1 and sell it when it's over $1 to maintain the peg. Not magic.
I'm not sure how I feel about having it come from the rich and powerful, but I have to grudgingly admit that this is a true attempt at civil disobedience. If the health concerns are as severe as Alameda County says, they can and should arrest him.
I fine that explaining NiFi tends to be difficult, especially if you're an advanced user. This is because NiFi is extremely general purpose. I've used it for many different types of projects. That being said, here's a few use cases that are relatively easy to get started.

1. Move data from A to B

2. Move data from A to B, but perform some intermediate processing in-between (ETL)

3. Grab data from A, write it to [INSERT SYSTEM HERE] (Mongo, Kafka, many others)

4. Periodically run an arbitrary script or program (like cron but you can schedule in seconds)

Those are just some use cases that people tend to start off doing. It's important to note...the above doesn't sound very impressive until you think about the following features:

1. Build these pipeline completely from a UI. You can leverage custom code, but the number of processors that come out of the box is astounding. If you can think of it, it most likely already has something built-in.

2. By default safety nets. Data is backed by a high performance WAL that allows for recovering in the case of a failure.

3. Ability to pause and resume specific areas of a pipeline at any time. For example, you may have a processor that's receiving data and perhaps the database you write the data to is offline (or has moved). Data is automatically buffered on disk so when the DB comes back online, you can backfill the data that you've been consuming. Further, none of the data was dropped in this process.

4. Tunable and verifiable back pressuring out of the box (_very_ hard to get right when writing custom code)

5. Easy to prioritize certain events over others (e.g. higher priority, latency sensitive data)

Lastly, when you start getting comfortable using NiFi, you will realize how general purpose the engine is. Data is represented as a "FlowFile". A "FlowFile" is essentially just a Array<Byte>. This means you can operate on virtually anything. Further, you can operate on large data since its backed by a WAL and NiFi facilitates the ability to stream data from disk when you want to process it. As long as you don't read the entire thing into memory (of course).

Easiest way to get started is to just download the binaries and run it. Then go to the http://localhost:8080/nifi and just mess around. There's plenty of tutorials online (Blogs, YouTube, etc). Once you get comfortable using NiFi, people will be blown away with how fast you can get something up and running. Things that would normally take days or weeks to get into production, you can routinely do it in hours or minutes.

Hope this helps!

edit: You can download from https://nifi.apache.org/download.html. Just unzip/untar the package and run "./bin/nifi.sh run"

More importantly, I don't understand what this model is trying to conceptualize.

The hydrostatic analogy helps a person understand the difference between voltage and current. But its real power is it gives you the building blocks that lets you understand more complicated behaviors by analogy.

Take power in the P=I*V sense. Pretending it's water, we can see how a supersoaker nozzle (ie high voltage, low current) is kinda moving the same amount of water in a unit of time as say a soda bottle tipped on its side (ie low voltage, high current). With the hydrostatic analogy, I can see how high voltage and high current are two different "things", AND I can extend those analogies to see how they explain additional concepts like power. That's a great mental framework! Now that I understand the basic dynamics and feel comfortable moving into the land of mathematical expressions, we can take off the training wheels and start talking about the really abstract stuff like capacitance.

On the other hand, I'm not sure what is the explanatory power of this "meshing gears" analogy. If you were to use this to explain electricity in say a high school physics class, what concept or insight does it help me grasp?

Theories for why there are fewer startups now
Secretaries were and still are generic, unspecialised workers. I think the 'team librarian' idea assumes some level of technical knowledge.

When I think of my own company, such a person would ideally be tasked with reading the user guides of the tools we use and quickly answering questions of the form "can we do this with it?", amongst other things.

This article is good but like others it focuses on the problem of getting people to write. I've found it's much harder to get people to read. The dirty secret of most workplaces is the massive disparities in reading speed that exist and the subtle tensions that can cause. It's something myself and my manager have both wrestled with, as we both read much faster than some of the other less technical people in the firm, and thus don't think much of dropping a six page memo on people or having long/complex discussions on Slack. Then they get frustrated at the implied expectation (sometimes that they put on themselves) to read it all.
Next logical step will be only accepting links to whitelisted domains.

> What I did say is that GPU porting of offline renderers is a waste of time better spent otherwise.

Not true. You can get speedups of 10x-100x by moving to the GPU. There is no known alternative way to spend your time to achieve the same outcome with the same effort. Using ideal (unachievable) perfect importance sampling algorithms might give you 2x, in some cases, if you're lucky.

What is making you think that people aren't improving their rendering algos or renderers, or that GPUs are preventing other improvements?

> And that denoising is solving a problem you would have less off if you didn't waste time with the former. And that 3Delight is proof of that.

Not true. You can't get rid of the need for denoising when using Monte Carlo path tracing techniques, and 3Delight's geo light sampling does not in any way demonstrate that you can.
If you mean that this demonstrates good leadership, I ask you, how?

Elon Musk is violating rules intended to keep people safe. And he's doing so to keep a business running that benefits him more than any of his employees. (You could make a different argument if this were a worker-owned cooperative.)

Is it good leadership because he's asking that only he be arrested? I don't think anyone on HN believes Elon will actually go to jail. Good leadership because he's (saying that he is) on the line? Elon cosplaying as an assembly line worker for a day doesn't make him a good leader.

A good leader would be doing their best to keep their employees safe. Putting thousands of people at risk in order to qualify for another round of stock incentive is not good leadership, no more what theatrics he's publicizing on Twitter.

Ah, this makes a lot of sense, thank you. Much like there are spectrums of light we can't see that can damage the eyes.
> What if 90% significantly cut consumption? Ultimately the companies have to sell their products to somebody.

Well, that's almost the interesting question.

A certain percentage of what the 90% consume, they can't stop consuming. You have to eat. You have to wear clothes. You have to live somewhere. You have to go to the doctor. So there's a whole big chunk that the 90% really can't stop consuming.

And if you want to be in the upper parts of that 90%, you need a computer, a car, a cell phone, college... So there's a bunch more of that where the 90% could stop consuming, but it would be a pretty significant sacrifice.

And for the remainder, there's an entire marketing industry manipulating us to make sure we don't stop consuming. Even as someone who actively tries be aware of marketing and remove marketing from my life I catch myself sometimes falling for it, and buying things I don't want or need. And I'm sure there are times it happens when I don't notice it. A significant part of Hacker News thinks advertisers are just out to help us find products we need!

The proles will never revolt, Winston.

The interesting question isn't really whether people will voluntarily cut consumption. It's more, "What will happen if the bottom 90% loses the income necessary to consume?"

Cynically, I think that won't happen, and the top 10% will just make enough concessions to keep the 90% alive and not revolting. We already see that in things like Amazon's $15 minimum wage: it's not a meaningful wage when Bezos is making $9 million/hour, but they can always make arguments like, "We're paying more than our competitors" and "We're preventing homelessness".

And that's not necessarily a bad thing: I want to see change, but I'd rather see it happen slowly through education and care than quickly with blood running in the streets.

There are some pretty well-mounted contemporary (i.e. last 20 years) defences of Marx's formulation of "the labour theory of value" (the terminology is up for debate, since Marx never used that phrase himself, and his theory is distinct from Smith's and Ricardo's) and the theory's normative conclusions. These defences come from philosophers and heterodox economists alike.

There's a Reddit comment here[0] with links to them, but it's up to you to decide if they're worthwhile or not. I have some doubts, but I would not go as far as to throw the word "discredited" in so casually. The comment also includes links to research against the "LTV".

Crypto can be priced in anything, including gold. Please think a little before posting like this. It ruins the quality of discussion.
So what happened? Did the price go up or down?

Bitcoin fans claims the price should go up. Conventional financial wisdom is that the price of something contains expected future events, so the price should remain the same.

True, though I'd also have to have faith that the exchange remains solvent and that an upwards run in Tether (and it does run up ~10% from time to time) doesn't blow through my collateral -- on top of my other concerns. I think there's easier ways to make money, after all Madoff's scam took 40 years to unravel. I'm not willing to wait that long.
I used to use a gravitational field analogy when teaching Secondary school physics.

Electrons are equivalent to "balls" with mass. Potential difference equates to a gravitational field (which most people seem to intuitively understand from experience). Balls can roll down slopes of different gradients, and therefore at different speeds, which is analogous to current and resistance.

It worked for me.
Exactly, just like how workers get paid a salary in accordance with the real-world costs they bear in order to produce their output...er wait, this isn't how prices work is it?

That sounds like any algorithimic implementation would be doomed to spread misinformation out of a misguided sense of fairness. It sounds very "teach the controversy".

Falsehood is not equal to fact. Favoring the truth but expecting even a human process would be foolish, an algorithic one even more so.
That does not solve the issues that Zoom has/had with encryption nor with leaking info. In addition there have been all kinds of sandbox escapes in the past. Finally I would not trust some random non-free program by Microsoft none the less to be secure, especially not against state attackers.
I believe these require a blood draw.
Makes sense, but I wouldn't call it an "interactive copy".
You could have said that in every bull run. You could also say that about the S&P, if it's going to be worth more later why isn't it instantly that price now? And it's because it simply isn't worth that now plus different investors have different investment periods.
Your typical factory pattern is an example of the OCP; move the part that changes into its own class (a factory). The class that uses the factory is closed to changes, but open to extension (new factory types).

Perhaps it's not the SOLID principles that are bad, but they way you've seen them used? More important than the principles is how they're interpreted and implemented, I think.
Tether didn't always exist
If your project is unlike your normal work it can make sense to use something new.

I was doing some niche amateur cryptography. I started with numpy, but I needed high performance and support for custom fields (e.g. cyclotomic polynomial rings) so I switched to Julia.

The learning curve was worth the expressiveness and conciseness of the new language. It's important that your code matches the abstraction of your problem domain.

Thanks for the link to the Vidor, unfortunate it wasn't more functional. It'll happen someday and when it does I'll be very excited, I know that there are already hybrid FPGA/microcontroller chips as an alternative to putting a softcore microcontroller on the FPGA itself (and wasting a lot more space and speed than needed).

I await the day when I can be like "nah, pin 2 will be a 16-bit 10MHz PWM output controlled by this register and pin 7 will be a frequency counter" and then access that with code on the microcontroller as if it was a built in peripheral.

I'm kind of skeptical I'll ever really get into FPGAs otherwise, my use case for them is always so simple, at the level of... well... PWM outputs and PID loops. But a microcontroller is fast enough for most PID loops so really to me the advantage is customizable function-pin mappings. I can't imagine trying to implement something like an ethernet stack on an FPGA though, although I guess you can run DOOM on one so maybe there will be a compiler from C++ to FPGA somehow that's not comically bad. ;-)

It's clear that a lot of work went in to this video and it's hard to hear criticism, especially of a labor of love. At the same time, I'd really like to see better analogies used for electricity, and that's going to require some very high quality work to replace the ones currently used.

The background music was quite bad and distracted a lot from the dialogue. (While I personally usually like the sound of bagpipes, most people seem to hate them, so that's an especially bad sound to use.) The background music is tonally too close to the speaker's voice, so the two together sound like the speaker is having to compete with the background music.

The constantly-shifting background and the nonstop fluctations of the hydrogen atom both also distracted from the core concept. Especially because the starry background kept changing direction!

The video uses vocabulary that isn't going to make intuitive sense to novices. Examples: "radial distribution function", "quantum jumping", "drift velocity", "multipolar contacts".

The clockwise-vs-counter-clockwise rotation thing never occupies the same frame in the video, so the watcher is expected to keep track of this mentally. Some people really struggle with that.

The advantage of other models of electricity is that they relate it to things that many people have experienced. This model is much more abstract. Abstract can be okay, but you should show reasons why the abstract model is better than the more relatable models. What's wrong with the other models? You say, "For example, it has some serious advantages over the traditional visualizations like the 'electron bead flow' and 'water-pressure analogy'", and you kind of describe one flaw of each of the two other models, but you don't describe why, in practical terms, this is problematic for understanding electricity. Like, okay, the Bohr model doesn't match the reality of probability clouds and quantum effects, but how does this impact simple circuits?

I found that the first half of Feynman's QED did a pretty good job of trying to explain quantum behavior in more abstract terms than the traditional approaches to light-as-wave-and-quanta. I'd also recommend looking at videos from 3blue1brown on YouTube for some ideas on how to present abstract concepts to viewers without breaking the bank on production.
NiFi is also very useful for visually chaining together scripts (e.g. foo | bar | baz). In NiFi you can use ExecuteProcess and ExecuteStreamCommand to basically do what pipes (|) does. Further, the intermediate data between each process is backed by a WAL. You can also mix and match your pipeline, for example you can mix-in some of your custom scripts, and periodically use built-in processors that are provided to do additional stuff (e.g. PutKafka).
