Great FAQ, well explained, clear action buttons. And you don't have 'amazon' in the bot name which makes it more generic for the future.

It took me a bit to realize the voice in the video imitates Milton from the movie, I found it a bit hard to understand.

Our office uses https://www.amazon.com/gp/pantry/info to restock the kitchen cleaning utensils regularly for example, not sure if Amazon has special API calls for that or if regular orders/reminders are on your roadmap.
Hard to say. At one time you could turn up and sit a City & Guilds exam, of course to become a bonafide amateur you had to pass the Morse test, but they've relaxed that now.
I went from UK Foundation licence to Full licence in about a year, not difficult from a technical point of view as I was working on 500kW broadcast transmitters at the time. The questions about the arcane rules and regulations were probably the hardest.
UK amateur radio is quite set in its ways, the average age of UK amateurs is probably around 60. Some of it probably stems from elitism and from some of the UK history of radio piracy.

That's a rather odd statement. Can you justify that?
Is there any link to intellectual property theft? I always wonder about the need to steal our intellectual property when China is doing so well with their own startups and innovations.
As an industry we have wasted an inordinate amount of time chasing methodologies that add little value.

In many ways we have gone backwards - I used to be able to hire a promising graduate and reliably turn them into a senior/lead in 3 years.
The Chinese left does not align with the American left. For one, unlike the American left who tone down patriotism, the Chinese left celebrates patriotism (as do the defacto right "Chinese" who are represented at least in spirit by Taiwan.). I mean, can you imagine the Chinese left celebrating with the Tibetan flag in the streets along with slogans implying China is racist and genocidal?
Tech workers: they're just like us – can't find affordable housing
> Shouldn't be too hard to write test cases for tax code.

I would disagree here -- like timezones, tax software has the disadvantage of being both extremely boring, and very fiddly (thus requiring close attention). This combination makes it very hard to maintain the concentration that's required to write exhaustive tests.
That's a great market idea. Hadn't considered it, but can see a lot of overlap with what we are doing. Will definitely keep it in mind for our product roadmap!
I don't know, maybe this sort of thing was better before Wikipedia? Now an hour or two of reading can answer pretty much all of this person's questions.
How about Xiaomi? Wikipedia says that as of 2017 they're the world's 5th largest smartphone company. I don't know how popular their products are in the US, but I have at least heard of them before (which is more than I can say for ZTE).
Just read the news release and they are claiming exactly that. Good on them--the Aurora/Redshift team has done some really outstanding work.
Play music (spotify, amazon music, pandora, etc), control any home automation you have (hue lights, etc), be a super easy hands-free kitchen timer ("Alexa, set a timer for 45 minutes"), answer basic information questions (forecast, store hours, unit conversions). If you have more than one, it can be an in-home intercom.

edit: I started this before you edited in your examples, so sorry for the overlap :-)
Couldn't you defeat ASICs pretty definitively (at least for a long time) by making the algorithm dependent upon a gigantic completely random substitution table? It would at the very least require ASICs to have giant amounts of ROM or RAM (with a memory controller etc) which would multiply ASIC cost.

AFIAK for today's ASICs a table larger than a few megabytes would be a strong deterrent. Go really big (e.g. 64mb) and you'd have some margin.

This would also be completely deadly to GPUs, especially if combined with branches and complex algorithms.

Edit: even worse: perturb the table using entropy from the block chain, making it impossible to burn into ROM and requiring tons of on-board RAM or a memory controller.
"...Well, that's the real problem, isn't it? If users aren't punishing Facebook by leaving the platform in droves, then what incentive does Facebook have to stop its consistently user-hostile business practices?..."

And the reason they're not leaving and don't want to leave? Where else are you going to connect up with old friends and remote family members?

I said it when Facebook started growing like gangbusters. Facebook is the frickin' devil. It uses your friends and family against you. For a free service, it sure costs like hell.
Those cans are filled with transformer oil, which until relatively recently consisted mostly of polychlorinated biphenyls or PCBs. Imagine how many of those cans exist across the United States and you get a sense of how big the PCB industry used to be, and why rivers such as the Hudson in New York [1] and the Housatonic in Massachusetts [2] are polluted with olympic swimming-pool sized quantities of the durable oily poison.

PCBs were used because they are really good thermal conductors, which is the same property desired of cooking oil for frying. In recent years, thieves in Kenya (which has yet to replace PCBs with something less toxic) have been vandalizing [3] transformers and selling the oil to street vendors, which has the twin effects of destroying the fragile electrical infrastructure and poisoning the neighborhood.

I think that’s a fair distinction to make.
I use my dot almost exclusively for music. Hook it up to a nice stereo system and it turns a dumb stereo system into a Spotify device that i can control with my voice or from my phone.
do you happen to know b/e costs given difficulty/profitability ratio using current market electricity prices?
I agree with you.

Its most useful features so far have worked best in the bedroom.

Alexa, set my alarm for 7AM. Wake me up in 2 hours. what's the weather in X? What's my commute? Nightlight.

That's about it.
I find it useful for just three things:

1. Play music

2. Timers, especially when cooking

3. Turn lights and heating on and off. It's nice to be able to control them while in bed with just your voice.

Nothing I couldn't live without, but it adds convenience.
That’s naive. When great powers have common goals, they cooperate just fine:

Postgraphile is very nice because you only need a PostgreSQL and a front-end app with Postgraphile in between. No need to write tiedous middleware functions. And it watches your DB schema and automatically generates a documentation for GraphIQL. Nice piece of software !
That's what people told me last time the issue of wsj articles on Google/YouTube came up.
> you could also just dust off the original specification.

You must be new here. What specification? Oh dear.
Now: For two phase in your home, why is one side considered "hot" and the other side considered "neutral", resulting in keyed plug blades?
> it's not a worthy contender in the market at this point

However I'm not aware there's anything else comparable on the market: 7 separate tweeters with 7 amplifiers in such a small unit -- which to me means it's much more capable in reducing distortions compared to anything it competes with. In short, I don't know there's any exact contender in the market.

The capability to control distortions by using the separate amplifiers and a fast CPU means that any reviewer who compares it with anything else while keeping it in the middle of the room is missing the point. This device is supposedly made to sound good when located on the place where the "audiophile" wouldn't put, that is, where "normal" people put the devices, not because they spend the energy to figure out what sounds best but because the convenience, existing furniture etc. Whoever can organize the whole room around the best sound doesn't have to buy anything small anyway.
It also supports spotify, pandora, etc.

For me Alexa is great for Home Automation (which while turning off the lights is a night party trick, it's pretty great to turn down the lights when you're already on the couch. Yes, 100% unneeded, but it is nice.), Cheap Sonos Style Music in Every Room sync'd, and yes, ordering stuff from Amazon. Again, totally unneeded, but for certain goods, I've found it nice to just say, "Alex, order me more blah" and it replies, "These that you recently ordered?" "Yep" "Ok. Done."

All of this isn't stuff you need, but hey, it's pretty rad nerd stuff.

Once upon a time, there was something called a "personal computer", which executed any program chosen by the person who paid for the device.

There is no technical reason why an Apple speaker could not be connected to Alexa, Google or private/niche speech recognition, when desired by the person who paid for the speaker.

This is a $350 device which runs only one app. Why?
I knew they would do something like this so I never put it in.
Pretty much on the money. The hardware guys tried though. Management delayed and delayed until they'd blown all the money.

In 90-91 ish they had a prototype AAA architecture and the specs were great. (3000+). PC's had caught up some way.

Instead management pushed a cheap, horrible, slower machine with none of the features, no SCSI II but CPU driven IDE and AGA in place of AAA. No DSP or voice recognition. No 16 bit Paula. That was A4000.

Then in 93(?) there was the planned 3D PowerPC reboot as PCs had finally caught up with AAA! Then they were no more.

Was really depressing going to DevCons and getting all the NDA info in this period.

I don't understand music quality arguments with these small systems - Sonos/Homepod/etc.

Get proper speakers - 8.5" drivers ($600) and a decent amplifier (Yamaha $250). This stereo will out compete any of these intelligent speakers.

Whats missing (except Alexa) is an auxiliary audio out that can be hooked up to existing system like the one I mentioned above. Google Home doesn't have it but it works with Chromcast add on. I personally use apple TV as my Airplay hub. So, about all that's missing is a microphone.

I simply do not understand - perhaps I am a minority - the argument and discussion around sound quality. There is no replacement in my opinion to a standard large diameter floor standing speaker. If I want to listen to music, I don't want any compromise - I want to be able to play it on my main stereo. Some people just don't care and they'll put music on their phone or some random bluetooth doodad. Why?
> to install any software on your Apple phone you had to use Apple's music player

Uh...no? Not sure where you got that from.
Proof of steak sounds delicious and would be enough to tempt me off the sidelines into investing.
The top comment from Arstechnica is:

> This will be absolutely fantastic for developing nations. Being able to bypass fiber-optic backbones for consumer connections will be a huge benefit. Imagine how many rural villages will be able to set up a couple of receivers to share among the residents.

Am I right in understanding that the intention is that SpaceX would act as the ISP in this satellite network? What are the implications for places like China where internet access is very much controlled by the government rather than some American billionaire? Are SpaceX going to breach the great firewall?
Community colleges are significantly more expensive for international students; at the local ones nearby you're looking at paying 4-5x more.

The data is a little flawed, but the point remains. Unless you already did well before or got in early, you probably can't afford to live near a lot of the really big tech companies.

I get daily use from my two echos with these functions: set a timer for x minutes, remind me to x at y am/pm, set an alarm for y am/pm, connect to my phone (so I can play bluetooth music), what time is it (when I'm in bed at night; I prefer not to have a bright clock splitting the darkness). A lot of this stuff my phone can already do, but it's easier not having to always pull out my phone. I've never used it for ordering, amazon music, lights, or to ask it questions for its biased responses.
Thanks! I can't wait to have enough traffic to actually run into the problems you described. I'd say if there are people out there going out of their way to game it, that would be a good sign it's having an impact.
Tesla also happens to run on dead dinosaurs, at least in the US...

Arguably less efficient since it has to be converted into electricity first. About 64% of electricity in 2016 was generated using coal or natural gas in the US. [0]

Maybe that's a way to give Detroit hosts an incentive to stay on Airbnb. After all, the more money they make the more likely they are to still use Airbnb despite the new city rules. So pushing more demand towards Detroit will reduce the number of hosts who decide to leave the platform (and possibly attract new hosts).

I think it can make sense from a business standpoint. It is unfortunate it hurts other hosts who have nothing to do with it. But I would guess this is just temporary.

They don't think the rules apply to them, so they don't care what the rules are.
> There are three because that is one way to change the three-phase power to single-phase, something I wish I understood better.

No, that's not correct.

Three transformers is for changing 3 phase medium power, to 3 phase regular voltage (for commercial customers).

For single phase home customers, you run a single one of those phases along a street and attach center tapped transformers to it.

The center tap means from the top to the center is 120v, and from the center to the bottom is another 120v. This gives something called "split phase", and is how homes in the US are wired.

This allows you to get 240v in the house if you need it by attaching to the top and bottom of the transformer.

The center tap of the transformer is also attached to the ground, and to the neutral power line (back to the generator). This gives what is called "zero voltage" (voltage is always relative, there is no such thing as absolute zero voltage - so you just have to pick something, and call it zero).
The original iPhone made a point of doing three things well: being an iPod, being a phone, and being a mobile internet appliance. Basically everybody had a phone and an iPod at the time, the combination was enough to sell a lot of people. Having an excellent real browser and very good mail app certainly helped a lot. But I think the "third heat" effect there had a lot to do with the success of it.

The HomePod will not be saved by being the best at one of the two or three major functions of these things, when it is so absolutely sucky at the other two. I'm sure a cult following will develop around the audio quality. But this product is going to fail unless they address the elephant: Siri is worst-in-class on an iPhone, and it's apparently even more hampered on the HomePod. What are the "platform" effects you think are going to sell this, like the original iPhone had? What exactly could Apple do to enhance this, beyond the obvious one of getting Siri to work?

Apple TV is kind of in a similar boat. The sales numbers are not that great, the competition is stiff, and the refreshed Apple TV has continued to not get enough love to really address this. They just seem like they can't keep it together.
CommonMark Is a Useful, High-Quality Project
My wife is 6'2", any plans for longer pairs? There is definitely a market for them, particularly internationally.
The two hot wires are perfectly out of phase, so connecting to both of them gives you 240V outlets (used for large appliances like clothes dryers).

Your standard 120V appliance outlets are only using a single phase and neutral. IIRC the smaller prong is hot and the larger prong is neutral.
>And the reason they're not leaving and don't want to leave? Where else are you going to connect up with old friends and remote family members?

Pick up the phone. There's FaceTime, Skype, text messages, actual phone calls, going to visit, sending letters, sending emails.

Or, if you can't be bothered to do any of that maybe you should not even bother trying to connect?
Hooking it up to my lights and playing music is nice, but honestly having a hands-free timer when cooking can't be beat.

So yes, a $40 timer. Still worth it.

Usually for music, pitch is another term for the frequency of the fundamental tone. So, a sine wave at 440 Hz will seem to the ear to have the same pitch as the open A string on a violin or the first A above middle C on a piano, and the same for other frequencies, pitches, and musical instruments. E.g., we can tune a whole orchestra with just a single tuning fork for A4 at 440 Hz, and when the whole orchestra plays A it sounds good, that is, without beats from the fundamental frequencies of some of the instruments being a few Hz away from a whole number multiple or fraction of 440 Hz.

However, IIRC, this simple relationship between frequency of the fundamental and pitch to the ear does not hold well for all possible periodic sounds.

Here's an interesting take on the state of agile and a way for modern best practices to be created and shared. Calling it the #RetroOnAgile. https://hackernoon.com/making-agile-open-source-retroonagile....

What's a typical range of amperage for a distribution line?
Because not everyone can afford ASIC's, which puts the mining power solely in the hands of those who can afford the hardware.

This once again reduces the playing field to a small, powerful group of players and essentially no one else can participate. Doesn't this defeat the purpose of a decentralised currency based on not having "trusted nodes"?
Read The Mythical Man-Month, internalize it, and realize nothing ever changes.

Organizations took up "Agile" because they wanted to be "agile." But Agile is not agile. Not even slightly. In most organizations, it devolves into Painful Waterfall. Or Yelling At My Boss Waterfall. Or Product Yelling At Boss Yelling At You Yelling At Each Other Waterfall. Not even joking here. Dead serious.

Corporations pick up Agile because they want to chase their hopes and dreams like the precious blossoming start-up they wish to be. It's a risk-averse way to dabble in the shark-invested start-up waters. In almost every start-up I've been in, I've had ssh access to production servers and modified production databases. When your business is facing life or death, all niceties go out the window. That unit test won't matter when your company goes under in a week. Big corporations don't see that, though. They just see the scrappy start-up eating their lunch.

HomePod Owners Still Plagued with Setup Issues
It depends on how they are used, but frequently, yes. Even so, you can sell to accredited investors totally legally. A few ICOs have worked this way.

ASICs are only costly from an R&D perspective. Which means once someone has all the R&D, they can be a monopoly and get really cheap hashrate, and since they are an incumbent monopoly it's much harder for another company to step in and complete.

FPGAs don't suffer this problem
The issue with the GPL is, that it does not only requires to pass on the source any (modified) GPL component, but also any other program part which happens to be linked together with the GPL code, but is in no way derived from it. This is pretty violent towards code not strictly related to the GPL code - whether the strong term used is appropriate, is another question.
I absolutely agree, and the fact that Apple TV works in such a configuration, but apparently is unable to pair permanently with the HomePod speaks to Apple's complete disorganization around this.
Ah. Here's one that was inspired by that one.

I've found Steven Smith's DSP guide to be quite good. http://www.dspguide.com/

That said it's all about the underlying math. If you want something with lots of source code to start playing around with you won't find it here. But since understanding the math is critical to understanding what the source is doing I think both sides are necessary.

Also this is yet another area of CS/engineering where C rules the roost. If you're not comfortable with C you'll have a lot of trouble using actual DSP hardware.
Polylactones are biodegradable polymers available right now, although i don't think they're particularly strong:

https://en.wikipedia.org/wiki/Polycaprolactone

If the fibers can be made cheaply and are biodegradable, then perhaps you could make deliberately and responsibly disposable tights, in which case their strength wouldn't matter as much. It's not as cool as super-strong hosiery, but thinking about it, i quite like the idea of disposable underwear!
