Ok, since I brought up THD as a bad measurement, let's take a look at what, exactly, is being measured. A standard THD test measures harmonics generated from a sine wave at 1khz, into a resistive output load.

So, how much does a 1khz sine wave represent an actual musical signal? And how much does a resistive load represent speaker impedance? The answers are "not at all", and "not at all". Do you see the problem yet? Of course you do.

And that's the problem with amplifier specs. They're measuring what is easy to measure, not what reflects sonic behavior. And it gets worse, because it leads to designing for specs rather than designing for sonics.

The easiest way to get "low distortion" spec-wise in an amp is large amounts of global negative feedback. But the negative feedback loop isn't just the outgoing signal. It also picks up back EMI from the speaker. A speaker is an electric motor, but it's also an electric generator hooked to a spring. Energy put into it is stored by and distorted by the suspension, then fed back into the output of the amplifier in a time and phase delayed manner. Yuck. And unless the output of the amplifier has infinite impedance (which it does not), then that back EMI is getting injected into the global negative feedback loop, doing things an 8 ohm resistor in the THD test doesn't do to the signal. The negative feedback loop is reducing input distortion, but increasing speaker EMI.

At which point the "distorted" impedance-matched output transformer of an old school tube amp starts looking like a much better proposition...
Is anyone complaining about this? These are mindless, terrible, Taylorized jobs.

The prosecutor dropped the case because the alleged rape victim didn't want to press charges, because she was overwhelmed in the immediate aftermath. Then she hired a lawyer to advocate for her who got the charges re-opened.

The other woman, who alleged lesser offenses, never dropped charges, though the statute of limitations have since expired on them.

Assange was told early on in the investigation that he was not restricted from traveling, but as the investigation developed further and it became clear they wanted to prosecute him, he went missing.

After multiple failed attempts to schedule another police interview, the prosecutor told his attorney she'd be filing an arrest warrant that day. Five hours later, Assange arrived at the airport and bought the next available ticket to Berlin.

Assange claims that's just a coincidence. That he was avoiding contact with his lawyer because he was afraid of "threatening statements made by politicians in the U.S"

No.

A company should be a long term short if you think that it is on a one-way path to going bankrupt.

But if it continues operating, be aware that the stock market as a whole goes up most of the time, and a rising tide tends to lift all boats. So odds are good that any individual operational company will go up over time.
Yeah I know, the same way each time I touch someone in the street, I get arrested for violently assaulting them. I'm really tired of trying not to touch anyone. /s

I know someone that was raped while not being conscious. She didn't want to have sex with that person. While trying to press charge, she found others persons that had similar experience with that guy. The cops told her tough luck, not to stay with people she didn't trust (it was a friend...) and they threaten her of making false accusation (the prosecutor herself seemed surprised of that and the cops angrily answered that she wouldn't be accused of that, luckily). The prosecutor has not enough proof to go further with it... there should have been at least someone else in that room that could testify.

That's the current state of rape accusation. Pretty far from your "kissing of a sleeping lover" being criminalized.
>About time a profitless company gets what it deserves.

Yes, a 63 billion dollar market cap is sure showing them!

>Tech companies have seemed to survive indefinitely bleeding VC money.

That's somewhat of the issue here. The outcome for VCs at this price is still somewhere between massive return and breaking even. It's the public at large that bought into the IPO via retirement funds that is hurting the most.

I worked two assembly line jobs. One feeding a robot with pre cut steel sections. The other wiring trucks. Both were non stop but just for 8 hour shifts. Both took physical energy and flexibility but were not back breaking (no more than the Amazon jobs anyway). I enjoyed them both and felt physically better at the end of the day than I do when I come home from a days coding. Everyone who worked with me needed the job and most were proud to have it. It was part of their identity.

Might you or anyone else know how big their float was on the IPO? Wouldn't the market punish the stock if they went back to the markets for a secondary offering too soon? For that matter what would even would be considered too soon? If they were to sustain their current loss rate wouldn't they have to return to the market sooner than later? Or are there some other instruments available to them that would be preferable to a secondary offering so soon after the IPO?
Does FedEx not do this already?
For smaller operations like mine, those older tractors are already valuable. I run Massey's from the 70's and 80's that I can fix on my own as long as I can find parts.

For large operations (and the way the entire ag economy is moving is large operations) this doesn't matter. They lease their machinery anyway, so what does it matter if they can't work on them? JD will come to the field to fix it if it breaks down. It's a cost savings for them.

As the other commentator said, they are too fragile to serve as humanity’s “back-up”. As theme parks or transit vessels, sure. But not as our back-up.

Second, and in my humble opinion more importantly, these will tend to be built and owned by entities and thus everyone in them will be serfs. I honestly can’t say that a similar scenario wouldn’t play out for a planet, claimed as owned by the first flag planted. But, when the structure is wholly built and owned by a profit driven entity such as Amazon... Perhaps they can be owned by consortiums or non for profit entities, there is still issue #1.

Finally. Why build one of these (gravity levels or for transit, I guess being the valid reason I can see, but maybe there is a planet-based solution for the gravity issue, idk) instead of utilizing the planets that are already right there for the using??? And instead of using all the resources to build a habitat, build something else.

We called that the 20-5-5 deal, and as someone that used Cloudflare and then went on to work there for a number of years, that is the only time I can remember Cf raising prices for something that had been fully released.

From my experience, features are added to the Enterprise offerings, and then eventually brought down to lower plan levels. However, most things are based on usage now, not plan level and I expect that is a better path to monetization for CF compared to simply raising prices.
Amazon has been quite the monopolistic company lately. Just because a company started winning by outdoing the competition doesn't mean that will continue to be their only way of succeeding. Even the most principled companies will adopt a few anticompetitive practices here and there when they get big.

I think with Amazon building out their delivery and subscription options, they can hold back a lot of pressure to share the savings from automation with consumers.
In the late 70s early 80s we all started to not litter so much in the US. There was a general movement towards this.

That is what they are doing with climate change. Do as I say, not as I do.
The problem with Uber (and Lyft) is that their losses are also scaling with “growth”.

As an alternative take amazon: they made a loss for years and years, but the size of their losses were reducing every year as they grew. The demonstrates a path to profit.

Of course for all these companies who have lost value post-IPO have already got the cash they were after. Post-IPO changes to value don’t change that and only impacts people who purchased at the inflated price.

Debuggers and property based testing. It is a select few people that can actually productively (not their own metrics) use print statements for debugging. Learning how to craft repro scenarios and adequately capturing state in a debugging session can enable junior devs to easily surpass senior devs.

Property based testing aren't quite formal methods, but I think they are a good stepping stone. And they also somewhat force your code into an algebraic/functional style which also make it amenable to refactoring, better testing and is easier to understand.

Design tools like Swagger can help one think through services w/o diving into code. Code itself is a liability and should be thought of as "spending" not creating. Code is a debt.

Refactoring and code understanding tools, if you use PyCharm (you should, it is free in all senses), learn how to navigate into your libraries. Read you libraries.
A few things come to mind:

1) It's a little unlikely that at the same time you have data where an {} is an error, but you are not making the property required AND with knowledge of that you still don't bother with other validation approaches. The point is that if you're aware that this property is potentially incorrect, you would want to check or restrict it. But yes, if this situation is completely unexpected, then "sum" won't notice any issues.

2) You have to remember that {} can arise from perfectly normal operations, such as filtering. So if you filter by a certain date range and there's no Payments there, then "(SELECT Payment FILTER .timestamp > <datetime>$date).amount" expression becomes {} even if the "amount" property itself is required. So doing a sum over it is simply a question of "What's the total amount in payments since $date?" and if there aren't any payments, the answer is 0, not {}. Plus what you certainly don't want is to get an {} from the "sum" here and do "{} + 100" to add some other charge (perhaps a sum from a different account) and still end up with {}, which now creates an error in a situation where there's nothing wrong with the data.

3) Rather than imbuing {} with special meaning to signal errors, a separate property would be more appropriate. Such as a boolean "valid" flag that gets set after the record checks out or can even be a dynamically computable expression that looks at the record (say, Payments from our example) and does something like "valid := EXISTS .amount". Then you'd filter things by the valid property before feeding them to "sum" like so:

SELECT sum( (SELECT Payment FILTER .valid).amount );
I'd love to know what knobs are turned at those companies to alter results, it's something of a trade secret I guess.

Just to see for myself, I picked a search that should churn up a guy that they might find irritating and did 10 seconds of anecdotal research.

Search was 'vox day blog'.

Google, Yandex, Startpage return his blog as the first entry (perhaps after an ad).
Goduckgo it was the sixth entry.
Bing, it never showed up. I got bored after the first dozen pages.

What exactly does this prove? Not being a web/seach engine guy I don't know.

What I'd like to find is a search engine for which I could build a great big list of curated sites with zero results from others. I tend to look up the same things a lot and after a year or two of additions it might be a really nice thing to have.

Don't go too overboard with message queues. There's nonzero development and operational overhead incurred when part of your application takes its input in a weird binary format, and when the data in your queue is thrown away after processing, and when you need to think about scaling of workers and concurrency. If you're not working with real "big data" – and, let's be honest, almost nobody is – I would advise using an HTTP-based service (REST, SOAP, whatever, take your pick) for communication and a SQL/NoSQL/NewSQL database for state.
Exactly - these thing as designed by ONeil are HUGE - 30 km long on the "default" island three type.

The solid walls would be meters thick, so the projectile would have to be very masive and/or very fast. And even then it would take a long time for pressure to reach dangerously low levels.
I dislike Uber's corporate culture intensely - enough so that I've used nothing but Lyft for years now. I have no idea how this company has continually gotten away with the crap they've done over the years - from rapant sexism, through privacy violations, to outright law breaking, to manslaughter.

No one at the company, nor any of it's investors, deserve to be rewarded with a high stock price. I really hope this company falls, and falls hard.
I wasn't alive during the 60s and 70s, but from everything I've read and watched of that era, I don't think this has ever been true.
If my anecdotal experience of Amazon deliveries is anything to go by, the mistakes may well have been made by a computer - on a couple of occasions I've received the wrong item, then gotten in touch with Amazon whose customer service have apologised big time, then sent me another item - only to have another incorrect item arrive a few days later. Another E-mail to Amazon, another apology, another incorrect item in my mailbox a few days later. My guess is the bins containing the items have been labelled incorrectly, thus leading the poor warehouse worker to pick the wrong item time and time again.

Robots will make the same mistake, only faster. :/
> So long as the hack didn't cause the problem they are legally obligated to honor the warranty.

I agree. The problem is that you could update the software to void the warranty, then do a factory reset when you have problems. Deere would never know that you operated the tractor outside of the parameters that they designed, built, and tested, but then they would be on the hook for it.

> Upping the fuel pressure and changing some maps should not cost the consumer $10k. The markup in that is ridiculous.

My numbers probably aren't that accurate, but they're not selling just software in that case. They've already bought an engine (for cheap) that is capable of that horsepower. They just don't realize the cost for it until they actually upgrade.
> Exxon is just giving people what they want. The blame rests with people who want a lifestyle that's incompatible with avoiding climate change, not the companies that simply are feeding consumer demand.

Well, Purdue Pharma is also only giving people what they want. In and of itself, that doesn't mean much.

Exxon is doing significantly more than just giving people what they want [1], as do many (most?) of the big dinosaurs of the established industries that currently make the world go round. Do we need to go into the vast efforts at influencing the public that such entities expend in order to maintain their domination and wealth? You have vastly more expertise on this subject, so I wouldn't be able to tell you anything new.

The world does need to advance, but advance to where? Thermodynamically, it must slow down or it will overheat and crash into the ceiling.

> Not only is there no solution that allows us to keep living the way we are living while averting climate change. There never was. Even if we had listened to the hippies and cut U.S. emissions by half starting in the 1960s, China's growth alone would have completely wiped out that savings multiple times over.

You don't know that, and it's a false dilemma anyway. People change their lifestyles all the time in response to their economic environment and incentives, as they have been doing throughout history.

I tend to listen more to the experts when they say something is possible. When they tell me in no uncertain terms that a very important problem has no solution, I listen more to the kids.

This is most certainly a trap.

They're going to start their business, and then Amazon is going to drop the prices they pay them, and the employees will be trapped because of investment of their own money and sunk costs.

Research Confirms Ride-Hailing Companies Are Causing a Ton of Traffic Congestion
The Skip language (which I mentioned in another comment) is a language based entirely on incremental computation. Every piece of code you write in it becomes incremental, as far as I know.

AND the compiler is self-hosted!!! So that means they have a fully incremental compiler.

Although there is an LLVM back end, so maybe only the front end of the compiler is incremental? That's still important. It comes from the same people as the Hack language, which I believe has a fast "online" typechecker -- which I think is incremental (?)

I believe you could write a C compiler in Skip the same way?

If you peek at the source code, it has a 6000 line recursive descent parser, and 6000 line type checker, much in the style of OCaml (but in Skip).

I think this deserves a blog post because it's not clear to me that the message of Skip got through (7 months ago on HN). Their website has some examples, but not too many.

Of course, I haven't tried it yet, and it's a super ambitious project, so there could be some big problem with it.

But if the goal is to make an entire suite of compiler and devtools that are incremental, then Skip seems like it's ahead of the state of the art and something to borrow from.

Salsa was also mentioned, and I believe it's based on some of the same academic work like Adapton. But I don't know if they have an entire self-hosted compiler as a demo like Skip does. It seems to be "query-oriented" rather than supporting arbitrary code, which is what I would expect for most incremental computing frameworks. Skip seems to be more ambitious.

I believe that the Skip language does this, because it's compiler is self-hosted. It's

The steep decline (vs. the market at large) so far today seems like a reflection of an investor flight to security (and away from risk) during a highly volatile situation the stock market.

Curiously, another recently IPO'd company, Beyond Meat, is currently up 3.75% on the same day that ride-share companies are down 7-11%, and the market at large is down 3-5%. That suggests that investors at least, have some pretty high confidence in alt-meat companies.

>Anti-recycling myth #3: Landfill space is cheap and abundant.

> Fact: Landfill space is a commodity, priced according to supply and demand. The majority of the growth of recycling in the United States has occurred in populated regions where landfills are expensive relative to the U.S. average.

I stared at this for a while trying to get at the heart of the issue. The response isn't "no, there isn't space." More like, market forces show that it isn't cheaper than recycling.

Perhaps the argument use to be "why bother recycling at all if creating new is cheaper"?

I think it's currently a de facto non-issue: Things that are worth recycling are being recycled, and things that aren't are going to be dumped/burned.

If the reality is as you describe it then John Deere is effectively a government entity now, there is no way the feds/state would actually allow them to collapse and all those fields to die off. If you work at or buy John Deere products you're just living on the taxpayer dime, call it what it is.

I'm not sure why half our economy suddenly seems to be structured around these "too essential to fail" business models, but it's brand new and really really stupid. I guess this is the end result of a generation of people coming up while a gaggle of billionaires get bailed out while absolutely nobody went to prison.
If that is true then why is wealth inequality so high? I have a hard time believing the argument that that wealth manifests as tech toys and amenities when the amounts of money that are in question here outweigh technology a million-fold.

UBI's an option -- one that I'm in favor of -- but as long as it is an idea and not reality there are still millions of people getting shafted without a lot of recourse, short of restructuring one's entire life and starting over in a new career. An expensive and emotionally draining transition that weak-ass severance packages fail to adequately compensate for.

If corporate tax payers were actually paying taxes and not sitting on a dragon's hoard of cash I might be more in favor of increased automation, but the fact is reserves being as high as they are means that automation is not so necessary in many sectors short of unreasonable and unethical shareholder demands.
