That's not true, because the software 'mantissa' in that library still only has 52 bits of precision (2e-14%).

E.g. if you try to add $100 trillion + $0.01 using dinero.js, you still get underflow and the $0.01 disappears.

> The accusation here was about intentional behaviour, which would actually be criminal.

Is that the accusation? My understanding is the parent was trying to say that incentives can bias a professionals decision making.
I recently experienced something like this:

My patent attorney notified me that I had a small window to do X, and Y, or I can do Z later but it doesn't have the efficacy of X and Y.

What I knew was that my patent attorney just told me that I have to pay him four or five figures NOW or else. And that has the hallmarks of a bad investment, scams, or conflicts of interest.

Well, for different reasons, I was introduced to a seasoned "Non Practicing Entity" who also told me it was really important to do X and Y.

I went back to my patent attorney and did it. Granted, this wasn't amateur advice in the least bit, but you're right that it is unlikely to find someone to talk to whose personal biases would be more aligned.
Just to level to the playing field:

This also seems to be the case for alcohol use.

It stands to reason drug response follows a bell shaped curve, where most people fit in to the pleasant-effects most-of-the-time large area covered by the curve, and fewer people fall outside.

> Nobody is having those arguments anymore. There are many class-D amplifiers on the market now, and the best of these are dominating the upper reaches of the high end.

Not quite. Frankly, Class A or AB still has the upper hand from a pure sound quality perspective, and class D struggles to output sufficiently at high levels with lower levels of distortion in my experience.

That said, there have been many small class-D Amps from Lepai and Dayton that are excellent choices for near-field and non-demanding applications. They definitely have their place. The tech is advancing rapidly but it has not supplanted A or AB.

If you want some background in why there is still debate, I highly suggest reading some of Nelson Pass’ interviews and writings:

I think the parent commentor was referring to the problem that happens when you go to save.

(Which is, really, just a problem with how filesystems only allow files to be represented as little seek(2)able character devices. If there was an API that would let a userland program treat a [sparse] file's data as a vector of extents—and arbitrarily manipulate that vector, such as by creating a new raw on-disk extent, writing data to it, and then prepending it to the file's extents list—then this performance problem would disappear, without any filesystem even having to change its data architecture.)

It's bizarre how none of these chips seem to have a digital input. All my music is digital, and despite the modern rise of vinyl, I don't think that's unusual. If I want an amplifier like this then I'm forced to have a completely useless DAC/ADC pair degrading the signal quality. Does anybody know of an easily available class-D amplifier with digital input? You'd think that would be an obvious feature for a digital amplifier.
The Internet was originally designed in such times. But all of these IoT devices that accept unauthenticated commands from anywhere were not.
No, there are very few of them, maybe on the order of 10-100. The biggest factor in comp at many of these companies is tenure; large stock grant at Google or Facebook from 8 years ago has appreciated nicely as it vested.

You can definitely improve performance by choosing an embedding closely related to your task. In the future we're hoping to have more embeddings for specialized tasks.

Kind of surprisingly, though, if you get your embedding by training a deep neural network to do a fairly general task -- like denoising autoencoding, or classification with many classes -- it ends up being useful for a wide variety of other tasks. (You get the embedding out of the neural network by taking the activations of an intermediate layer.)

In some sense you'd expect this, since you'd hope that the intermediate layers of the neural network are learning general features -- if they were learning totally nongeneral features, it would be overfitting -- but I found it surprising when I first learned about it.
Just rumors I've heard but the people who make that much (and I've heard some crazy numbers) are people who have a lot of knowledge of proprietary systems internally in Google. I don't know if there are actually a lot of them though.

The UK is just very skewed, due to finance. I studied in the UK, and there was a 6 month placement internship programme.

Engineering firm (industrial measurement) wanted to pay me $11K to be an engineer. Marketing department at a major semiconductor said £15K. So I took it. My friend at Goldmans got £37K.

So guess what I did after uni. I even met loads of people in finance with engineering degrees who said they were now earning multiples of what their previous bosses in engineering were earning.

Anyway, if you do have tech skills, finance is after that. Particularly right now as all the trading is going full auto. Amazingly there are still places that don't have straight through processing in place, so plenty of work. At the fun end there's a lot of demand for people who can write trading algos, which I did for a long time.

This is after years of IT people in finance being second class citizens.

Of course they’re anecdotal - listening to music is a subjective experience. If someone really thinks their music sounds better after adding $100 cable lifters and taping $50 bags of rocks to their $10,000 system, they are automatically correct. Their ears, their hobby.

It would be like saying that something can’t work because it’s a placebo - even if all they’re getting is a sugar pill, if the symptoms went away, that’s not really something that you can argue with.

I put audiophiles on the same level as sommeliers. The best wine is the one that tastes best to the drinker. You can haul out your GCMS to test the wine and your ABX testing software to test the audio and tell someone their subjective experience is Wrong, but this misses the point. We’re not talking about medical efficacy here, we’re talking about artwork.

Not the poster that you're replying to, but my story is similar. I did my first 10-day Vipassana retreat while on an extended vacation.

Every word GP said feels like it describes my first experience. I had some pretty profound realizations while there and expected that it would be pretty life altering. However I took no care in how I re-entered life and the combination of immediately going back to using phone/computer and traveling around in a third-world country was almost more than I could handle. I felt like I was going crazy adapting back to a stressful world from one where my mind was so calm. I did try to continue meditating, but I found I had nowhere near the concentration I needed to get value from the practice.

But I resolved to try again, so I attended another 10-day retreat trying to apply lessons learned from my first attempt. The second time, I planned in advance to slowly re-integrate myself into my normal life. I booked a hotel room for a few days after the retreat to lock myself away and start adding back distractions one at a time. This worked better and I was able to keep up my meditation routine (1hr in the mornings, 1hr in the evenings) for 2 months after that. But I found that 2hrs/day mediation is pretty qualitatively different from the kind you get at the retreats (more than 8hrs /day). I still think daily meditation is valuable, but given its lesser impact and the distractions and stresses of everyday life, I just sort of fell out of practice and haven't restarted.

I am hopeful to do more retreats and do better at integrating meditation practice into my everyday life. But, suffice it to say, my first two attempts at that didn't succeed in a way that lasted more than the two months following my second retreat.

The Barclays app is fantastic, and very fully featured, but it’s fundamentally a port of a web banking experience with the UX of a team of UX experts who think they know how iOS apps should work better than Apple.

The Monzo iOS app is a completely mobile first rethink of banking. From the live nature of the balance, to the in-app chat (which works very well). On top of that, they don’t reimplement iOS conventions.

There’s a lot that could be improved about the Monzo iOS app. The whole service lacks features compared to Barclays (but, 450 vs 150k people, obviously), but it is still a step change in mobile banking.

Realistically, blind faith in professionals is as unrealistic as blind paranoia.

I don't think it's possible to say "Of course we should trust psychiatrists" in one sentence and then add "But of course we don't really know much about mental illness anyway" in the next.
The reality is that pharma in general has a mixed reputation, and psychiatric drug treatments have a very spotty scientific record - as do the various kinds of talking cure.

Psychiatrists probably won't encourage session dependency, but psychotherapists might - especially in countries where you can hang out a shingle with no training or background at all.

I find that the way of reading that gives me least eyestrain, is using a phone or a tablet with an OLED (important for "perfect blacks") screen, setting it to some warm color (e.g. orangeish yellow) on black, and dialing the brightness level down to exactly the point where it's readable without straining for a given background light level, but no brighter.

The benefit of this arrangement is that it works in a wide variety of lighting conditions. When I read at night in bed, there's practically no light around at all, and so I dial the brightness all the way down - and read without losing night vision.

Between the ability to do that, and the ability to adjust font size, I find e-books to be light years ahead of anything on paper, in terms of ergonomics.
If your listening needs don't involve more than 10-20 watts, inexpensive Class-D amps can sound really good through a pair of good speakers. And because of their efficiency, an external power supply only needs a handful of amps (much lighter). Win-win for me.
This is a Quora answer of mine from (sigh) 2011:

I _like_ vinyl, but I'm happy to admit its almost certainly due to non-audio non-hifi reasons. I like the "ceremony" associated with cleaning the disk, dropping the needle on the lead in track, and getting up to flip it over and do it again every 5 or 6 songs. I like the cover art - there is arguably a loss to the world of a beautiful art form due to the demise of the 12" record and it's large art-work ready packaging. And, as you'll hear on a lot of '90's CDs - I like the 33 1/3 rpm flaws, the clicks, scratches, and wow and flutter - when I hear the opening bars of Tear Drops from Massive Attack's Mezzanine, I get nostalgic, not for the late nineties when it was released, but for the early eighties - that scratched, fuzzy, played-too-much vinyl sound they used - that was the soundtrack to my late teens. Whatever the minor differences in the audio reproduction, those 33 1/3 and 45 rpm noises bring back some wonderful memories... Which is enough reason for me to keep the turntable set up and occasionally spin some discs...

An object, under OOP, doesn't have to have an associated execution thread, in order to decide when to do what.

Instead, picture an object as a closure over mutable state, where the closure accepts an arbitrary serialized term (the "message") which it can do anything it likes with.

Note how such a "closure object" can call its runtime's timer API to get another message sent to it later. It could even do this in its constructor.

Note also how such a "closure object" can reprogram itself, by holding onto other closures as part of its mutable internal state, and replacing these with other closures [e.g. ones passed in as part of the message] in response to messages.

These two properties together, mean that how a "closure object" responds to a message at a given time, is entirely up to the closure—it can have changed into something that does something entirely different from what its "bootstrap" source code says, at any point since the start of the process.

Most people won't reach T7 in 10 years.

The expectation for each level is:
L3: you are expected to do projects assigned to you well
L4: you are expected to lead a project in your team well
L5: you are expected to lead a project across multiple teams in your organization well
L6: you are expected to lead a project across multiple organizations well

I think the L6 engineer is basically a CTO role in many other companies. L7 is even beyond that.
Amen. Ask a guitarist. Kid needs a real guitar amp. And a couple of decent FX pedals.
I'm not surprised. From personal and friends experiences, Google will lowball you if you don't have any competing offers.
I'm not convinced audio engineers are having that argument anymore (which is more the audience of IEEE). I get the impression from an engineer I know who's specialized in digital signal processing, and who's done a significant amount of analog work, that anyone who's still having some of these arguments doesn't understand some of the basic maths of the problem space. That basically, you can always digitally encode an analog signal at a higher resolution and fidelity than you can reliably read said signal at any given technology level/pricepoint. Which means that using an ADC -> DAC pipeline will almost always give you better audio output with better signal to noise ratios than strict analog -> analog systems (though possibly at the cost of latency).

Where it gets tricky, is the arguments for how things like tube amps sound. There is nothing that analog components add to a sound that can't be simulated with digital transforms, but the trick is figuring out how various analog components effect the signal. For instance, my friend found that certain tube amps would overdrive components and force them out of spec, and this caused a non linearity in the response of the signal coming from the component that gave the amp it's distinctive distortion effect. Once he figured that out he was able to reproduce the effect digitally. Incidently, he's found that some guitar amps can never be made today, because they were built around a specific batch of a given component, and newer batches didn't have the same out of bounds responses. But this seems to be why so many people are still so big into analog amps, because it takes considerable effort (and apparently engineering skill) to reproduce some of the classic sounds.

Mind you, I'm biased by one of the best engineers I've ever met, so I could be wrong about the general consensus with audio engineers. I'm also mostly using a sample size of 1, though I have corroborated some of his assertions with some of the blogging I've read on the topic. One of the best (I wish I'd bookmarked), was a good overview of encoding by a prolific codec writer, who pointed out that even though a digitized sine wave looks lossy at a low sample rate, it's trivial to rebuild that sine wave perfectly, with just the digitized version (so long as the sample rate was above some multiple of the Nyquist frequency?).
