From the privacy perspective, IMO, once you put a device in your home that you know is always listening, and is forwarding an unknown amount of audio from your home to a third party, at that point, you have surrendered your right to privacy.

Also, the ship's crew are doing most maintenance underway, which keeps the asset producing value. Pretty much the only maintenance done on cargo ships at a port is stuff that requires a drydock. It's actually cheaper overall to have the maintenance crew ride the ship around the world (and also do the small number of sailing tasks that would be expensive to automate) than it is to take the ship out of service at ports to, say, repaint everything, or change the engine oil.
Building Conversational Apps Using Actions on Google and API.AI
mTCP is pretty sweet; I once ran it (IIRC) to set up an FTP server so I could transfer some files from the base system to a vbox VM running FreeDOS (I think it was to play around with some old QB4.5 code of mine from over a decade ago). To be honest, there was probably an easier way to do it, but I may have been hindered by the "draconian" rules we had on these machines (Win8 boxes, and we didn't have admin access) - or maybe I just wanted to see if it could be done. I don't really recall...
Yes. It is occasionally useful.

However when you have the right data structure, you'll find you won't need it.

Benchmarking is important because searching for the right data structure is time consuming (expensive for the programmer) and it's usually not necessary.
According to TSA PreCheck page[1] the same liquid limitations still apply, you just don't have to put them on the belt. I don't think this is about them being able to detect the threat liquids.

For the security checkpoint throughput it is important to avoid having to stop people and dig into their bags. I believe the reason for picking the liquids out of bag is just to make it faster for the security person to check you are not carrying too much. For PreCheck flyers this is not needed, since most of them are seasoned travelers and now the limits.

No, you haven't, any more than when you buy a cell phone with a camera and microphone built in. People still have rights regardless of the products they buy.
The US checkpoint in Sydney didn't strike me as too bad, especially considering they have to process an A380-load all at once.

Auckland is just terrible though. You get off a plane from the US and they put you through an undersized security chokepoint before allowing you to move to another terminal.
Can you elaborate on this? What is the tipping culture like in Thailand?

I presume you mean in Mexico that since everything is all-inclusive, the only real payment is tips so it strongly affects service quality.
(old-ish study, apologies, but was cutting edge circa 2010, but still stands re: LiFePO2 which I'm betting your '14 production car is using) -> http://ecec.mne.psu.edu/pubs/2010-zhang-jps.pdf Page 2, Column 2, Figure 1, Top chart. 300 deep-cycles @ ~92%, 600 @ 74%.

If you're the average SV guy who 'daily drives' his Tesla 20 miles from Oakland to his lofted startup where there's 220 to full-charge before you go home, you'll get 2%. Johnny in Kentucky working the coal miles doesn't have that luxury and will certainly enter into 'deep charge' consumption. (600 cycles -> ~75%, with 2nd deriv of batt life w/r/t cycle being negative, i.e., progressively decreasing losses).

Again, not in the field professionally, but these opinions are consistent with my friends who are working at the forefront (albeit, a statistically small sample space, I openly concede !)
It would probably help to add some text to the page saying what it is, e.g. "Check the dependency of a Python Library". For other people, a project is usually much less obvious than it is to its author to a surprising degree.

Can you express "a lot" as a percentage of existing capacity? Because it seems like, relative to the amount of cargo space these ships already have, that percentage would be pretty small.

One thing I've noticed recently at SEA is that there appears to be some sort of privatized PreCheck. I've had some guy come around with brochures for the company offering minimal lines/waiting to get through security if you signup for whatever the program is. Unfortunately, I'm having a hard time finding the company online.
Maybe next adminstration will introduce profiling, which seems an absurbs oversight after spending tens of billions on security, not to mention the time cost. Yoing Arab men should get more ecrutiny than old ladies in wheel chairs.
You could even convert it to text before sending.
If we want to be technical, it's a weighted random search based on historical observations.

It would be the exact opposite if 100% of the ethnically profiled individuals were terrorists.
I agree with this so much. Because of strict regulations, non-financial sales is infinitely worse than anything you'll see in finance.
Because the goal (or rather the means) of terrorists is to scare people. And it's much scarier to imagine your plane being blown up in the air.

Reason has nothing to do with it. The number of deaths due to car accidents, even falling down the stairs, is much greater. The main impact of terrorism is the irrational fear, not the rational risk aversion. But it's much easier to stamp out terrorism by force, hard as that may be, than to convert human beings into rational animals.

The goal of terrorists is to achieve power through violence. The gold standard would be the PLO, now the PA. The ANC also did extremely well with this strategy.

There are two effective ways to combat terrorism. One is to surrender to the terrorists. Neither the PLO, nor the ANC, nor the IRA, is setting off any bombs these days. Works great especially if surrounded by a cloud of euphemisms.

The other is to treat the terrorism as an isolated incident and counterattack on the political front. Consider the response to Timothy McVeigh or especially Dylann Roof -- textbook. Great stuff, America still knows how to do it.

If terrorism is committed in the name of the Confederate flag, ban the Confederate flag and crack down on white nationalists everywhere. Even the peaceful ones. Especially the peaceful ones. No one ever said that the best way to defeat racist terrorism is to satisfy the legitimate grievances of moderate racists. But if the USG adopted this strategy, the GOP would probably grow a "militant wing" in well under a decade...
Yes, on average the server at the high end restaurant did substantially more work, and they performed it more expertly.

they were better able to answer questions and offer suggestions (including off-menu changes that might help you). They timed your meal for your enjoyment rather than for turnover. They made sure you had fresh silverware, a clean table, and a full glass. They coordinated your bar, wine, and food orders so appropriate items were presented at the appropriate time. They verified the kitchen gave them correct dishes before they brought them to you. They devoted a lot of energy into ensuring that a small number of guests have a great experience.

They're able to earn decent livings because they are at the top of their field.

The folks at chili's are granted no autonomy. Their goal is to turn the table quickly, with the least effort; and to do this with the least skilled staff. They work hard, but their goal is to serve a large number of guests with a tolerable experience, not a great one.

Yes, they bring food and drink, but the focus is on throughput, not on quality.

It's similar to the difference between code written by a low bid contractor versus a talented on-site team. If you want anything unusual or if you care about quality and the experience, you'll greatly prefer the on site staff. Even if some execs might not understand why you can't offshore 100% of the work.
Yea that'd be cool. My email is in my profile. Thanks!
It makes some sense in that high end restaurants employ high end servers, who has more and better skills than Olive Gardeners, so they command a higher wage.
That's exactly what Gammel claimed to do in his original videos on this:

https://news.ycombinator.com/item?id=13260343

He pointed out that the classes were usually theory heavy where you do piles of math without building anything. He said the kits normally had you plug stuff up without understanding what's going on. So, he tried to do a course that was incremental and build-oriented like kits but gave you understanding of theory/concepts a bit at a time. I haven't used the service but it was only one that claimed to do this.

I travelled through the US from Mexico to Europe last year. Bought a nice bottle of Mezcal at the airport in Mexico, had it in a sealed bag to enable travel. TSA agent didn't trust the travel seal, so he took it out of the bag, scanned bottle with some cotton swabs put into a device (my guess is HPLC), it was OK so he re-sealed my bag with TSA tape so I could carry it on multiple flights in Europe.
It's a progressive charge.

If you have more money to spend, a lot of the time you'll end up spending more on desserts, drinks, etc. Then you pay a greater amount of money for the service. If you have less to spend, you'll buy fewer things, and pay a smaller charge.

> When is the appropriate time to intervene to ask if everything is ok?

Where I grew up (The Netherlands) this simply does not exist. If you need something you ask the waiter and only then they'll come to you. Likewise for the check, the check only comes when you ask for it. It is considered extremely rude to get the check before you've asked for it.

Of course, after living in the US for 5 years I've become accustomed to all kinds of weird things (like the insistence of having salad before the entree, and entree not being an appetizer, simply blows my mind).
In fact that's just 40gb per year, which is pretty doable even on a local SD card that Alexa could be fitted with. Or even if it stores one month and deletes the oldest one every day, that's still 3gb. Very doable.
As an American, I have always written both the tip and the total on the slip. Until this moment, I have never actually considered only writing one or the other.

I probably will continue to write both as I'm a little paranoid about people making changes to the values before they get put into the machine, and having to change 2 lines is harder than 1.
Not disagreeing entirely, but better examples would have been gay and trans, where the gay and trans people haven't changed very much but the medical and cultural response toward them has changed quite a bit over the last couple decades.

Also (original) OP seems to assume starvation mode is as healthy as normal mode, which is ... questionable at best. Yes if a tapeworm is sucking glucose out of your blood, as long as it doesn't suck too much and kill you, you'll either have to go into starvation fat burning mode essentially permanently as long as you're infected which might have some negative long term side effects, or you can try to live normally which will result in obesity. Aside from the medical problems from living in permanent starvation mode, I imagine the psychological experience is incredibly unpleasant.

From memory starvation is contraindicated for recovery from surgery, pregnancy, and athletic training. I wonder how many infected people die after a relatively boring surgery because either they're fat or they're starving so they can't recover correctly. Or miscarriages where the body thinks its in deep starvation mode so better the mother survive than take them both down, despite normal food intake. Aside from the obvious pregnancy complications from obesity, of course.

Any way you look at it, that virus needs eradicating.
When Ayn Rand Collected Social Security and Medicare, After Years of Opposition
ArXiv is incredibly useful for research, but I think people also use it for a sort of "I posted it to arXiv first, therefore I solved it first" kind of thing, which imo can be misleading at times, if not everyone follows that. Also there is the eprint.iacr.org which seems to do the same thing, except for cryptography (or is it cryptology?), so I'm not sure if every important preprint in that topic gets to arXiv.
Introduction – A-Frame
This still doesn't explain why it should be a percentage other than that everyone assumes a percentage.
A year of audio at 32kbps (more than enough for speech) is only 120GB. That's only a couple bucks of month on S3 -- at retail pricing. So it's technically and financially feasible to store everything if Amazon wanted to.
It would cost about $30m a year if you tailor the system to flagging specific data for storage and don't naively store every moment (e.g. you scrap silent moments and use VBR encoding).

Storing a year's worth of 96kbps audio costs 380GB. If you don't record silence and you assume the people around an Alexa are only speaking for at most 4 hours a day on average, that goes down to 76GB a year.

So if you then assume 5m Alexa's are active at any given point in time that works out to 380k PB. Ok, that doesn't work yet.

However, if you then layer on a flagging system, where only certain users' full record is stored, or only "suspicious incidents" are stored, and you get this down to only flagging 0.1% of all data, you arrive at 380PB of storage.

Amazon Glacier costs about $88.000 a year per PB, but there's a profit margin included in that, so I'll assume it costs Amazon just $75k a year.

In conclusion, it would cost Amazon about $28.5m a year to run such a system. That's certainly within the realm of possibility and of what LE/SIGINT clients would pay; I assume the NSA would gladly pay that sum x100 for that capability. Sounds like it'd be booming business for Amazon.
I've talked to several people from my home country who won't visit the US because they don't want to deal with the social trauma of deciding who to tip when and why.

Someone should look into how much this is costing the US tourism industry.

No need to carry around all of that extra bulk and weight on your body when when you can pack it into a wheeled carryon bag. You don't even need to keep it under carryon size since the airlines don't (usually) screen for size until you get to the gate.
There was, technically, but it was quite sketchy. For example, in Windows 95 the zero page was mapped to physical memory in order to workaround an ancient CPU bug... for which CPU support was later dropped anyway[0][1]; as far as I know, Windows 98 keeps doing this.

Try it yourself: run debug.com and type

It hangs the system even in Windows Me.

It would work better - but I'm pretty sure that the decisive factor was cost: back when this was conceived, getting a useful laser would have driven the cost 10x higher. Plus, I think there's some pesky law on coherent light output power and whatnot (and another which bans lasers outright if you're close enough to an airport).
Especially since Alexa already converts it to text! It wouldn't be outside the realms of possibility.

Would it be possible to test this? Check the battery life of the Dot in a completely silent room vs the battery life of a Dot listening to an audiobook played on repeat. If it is actually listening and transcribing it should have a higher power consumption and thus die faster - right?

> DOS programs were decoding MP3 in realtime in the mid-90's, on 90's hardware, just at lower bitrates.

Back "in the day" I built an AMD 5x86 machine with 4mb that ran DOS and could -just barely- decode 128K MP3s using some DOS-based MP3 player I found. On top of that, I ran a custom menu system (wrote it using TurboC iirc) that drove a 16x2 LCD via the parallel port. I had this idea that I would set it up as a car pc, but never actually did.
Yep, I'm amazed at myself on how much privacy I've given up for convenience from 10 years ago. As long as you know the trade-offs...

I've started smart-devicing my home and a little wary about that, not from a privacy perspective, but from a hacking perspective. I can almost imagine a sci-fi/horror movie there somewhere.
How many other words and sounds sound a bit like Alexa?
No, i think that was about them bundling IE with Windows and claiming they were joined at the hip.

That said, i think MS since then changed their tactic to offering deep bulk discounts. In particular when the OEMs pre-installed both Windows and Office.

This because the margins pr PC had become so thin that the way the OEMs make a profit is to charge third parties like Symantec a pr PC fee on bloatware bundling.

I asked an EE about that but got warned it's more like a reference book. He said the easiest book on electronics he ever saw was a Malvino book he stumbled on in a thrift store. I found one of its editions for $2 on Amazon. Great balance of explaining the basics, showing math, and practical advice of do's & don't.

You know, Dang, this whole thread is a flame war topic. Why didn't you delete that? Oh, I know why, because it supports your side of the ideological narrative.

All people are asking is that you apply your own rules to your own selves. It should be obvious by now that these double standards do not make for community harmony.
Well, however, we can argue here that a pre-print is not of the same quality as a published work. Not that published works cannot have errors (and be retracted), but at least they have passed a first-level scrutiny of an editorial board.

People have the rights they have agreed to. What does the EULA state? Privacy policy?
It seems like you're only classifying the physical labor as "work", and ignoring the skill and effort it takes to do all the stuff a waiter/waitress does. There's a lot of memorization involved, being able to answer a lot of different questions, making sure the meal gets delivered as soon as possible, with the right stuff, and checking back at the correct times to see if anything else is needed, including drinks. It's a lot harder than it seems.

The bussing jobs are a lot more physical and there's less to think about.

Also, he gets 10% of the tip... But where does the rest go? You're assuming the other 90% goes to the waiter/waitress, but it's possible a large portion of it goes to the kitchen staff.
For NLP research, you'd want something that preserved more information than text.

Questions for anyone in the field: how much is preserved? Is there a < audio but > text form that allows for iterative testing? Maybe the output of a first-pass pheneme decoder? If so, what kind of space requirements?
Someone that doesn't think it's worth paying the $85 fee for PreCheck is now an "evildoer"? There are a lot of people in this country that fly very rarely and for whom $85 is a lot of money.
It is also feasible the device could just wait and transmit only voice like data and drop other sound data... (Even my crummy baby monitor can detect the difference.)

Speaking of which I wonder what the net traffic usage of the Echo is?

The real problem with shared ports is that cars still occupy stations when they’re done charging, and they are not even required to “plug in” while using the convenient parking spots.

You need a way to force a car to start charging while parked in special spots, and force it to leave when done (the Tesla actually could move itself out of the way automatically, if only there weren’t a charging cable attached).
