Wait a minute, we'd already know if Alexa was recording everything by the network traffic that obviously has already been sniffed. We can assume that Amazon is storing every "Alex,..." query that you've ever done. So what is there to know?

Redis's "Protected Mode" was introduced a couple of years back iirc. It refuses to listen on anything besides localhost if you haven't configured authentication, unless you explicitly disable the protected mode flag.

If you're using the version of redis packaged in trusty/universe, it is extremely old and doesn't contain this. It also contains a handful of critical security vulns that are being openly exploited in the wild. Update manually TODAY.

Could it be that the cause for the problems was in 3rd party applications/drivers that were messing with the system in ways unexpected by Microsoft developers?

My feeling (not backed by any evidence) is that most of the BSOD bugs are actually related to faulty hardware or bad code from somebody else than Microsoft.
It is pretty controversial. The value of peer review has never really been demonstrated and despite peer review, the median scientific paper is wrong.

"Never really delete" is actually standard advice. There are loads of reasons, mostly non-nefarious, why you may want or need that data.

Sometimes deleted stuff is archived offline or in slow warehouse databases that are not live, etc.

Okay, you just conceded a point that negates any reasonable premise for your question that I can imagine at this time.

If everything is sort of tied in with environmental concerns, then why did you think I didn't read the article from start to end? If you didn't think that, then why did you feel the need to ask if I had?

I may be missing something obvious. I'd appreciate if someone could fill me in on what I missed.
Digital Marketing Weekly
This article misses one of the biggest value-adds of arXiv, at least in my field (Statistics): since almost everyone posts to arXiv, you can almost always find a free version of a published and potentially pay-walled paper. In the past, publishing in a peer-reviewed journal would (1) improve the paper through peer review, (2) signal the quality of the paper based on the prestige of the journal, and (3) distribute the paper. With arXiv, publishing now only does (1) and (2).
This sounds crass(?) to ask, but if we already have some, does more make it much worse?

At this point we HAVE some nuclear waste already. Safely storing nuclear waste is an extremely difficult problem, and one we have yet to fully solve.

But if I have X tons to store for 10k+ years, what's the marginal cost of increasing X by a factor of two, or ten, or a hundred? (And what sort of increase in X would we be looking at?)

If someone told me to figure out how to affordably and safely store five megatons of nuclear waste (rough number from a quick
Google search), I'd spend a lot of time with lots of experts figuring something out. If partway through you came back and said "oops, make that ten megatons", I might say "oh snap, our current site/plan doesn't scale", but I feel like it's more likely that I'd say "well, the bulk of the solution scales just fine". (Maybe the site wouldn't scale and the political NIMBY part would have to be redone, though, which is not a small problem.)

But I don't know! The fact that we haven't figured out the problem means maybe we should put some effort into that, but we if we're going to scale up nuclear, we should probably do it soon. Probably twenty years ago or so.

We know they are streaming it to do all the NLP in the cloud. This is obvious from the computational costs alone of doing NLP.

The important question here is "What happens to the audio data streamed to the cloud, a few seconds AFTER the query has been identified (or not identified) and the results sent back to the Alexa device?"

The nieve assumption is "all audio data is deleted after processing". The reality is that data is still valuable to Amazon for a variety of uses such as

(1) further training their voice recognition software

(2) advertising data mining [how many people are in the room, things they are talking about --- note, Facebook's mobile app infamously does this]

If they just store the query text, that is 'best case' from a privacy perspective. If they just store query text and query audio, that is less than ideal, but not too bad. If they store all audio, ever recorded, for an indefinite period of time... that is what this police request could reveal: Audio data stored for a non-keyword-trigger, and for days/weeks after the fact.
The Chatbot Will See You Now
I think you're orders of magnitude off in marginal cost estimates for glacier users. Datacenters are being built out for a small number of commercial users (e.g. Amazon's core business) and the size of modern HDDs would lead me to estimate that storage is about free in a modern datacenter, the scarce resource is disk-time for read/write operations. That is, projects like glacier let Amazon sell disk that would have otherwise been stranded.

It is also the case that a consumer level service like glacier presumably has more redundancy than what might be needed for best-effort storage of these recordings, where losing any fraction of them wouldn't really be a problem.
While I'm not disagreeing that a server at a high end restaurant has substantially more work to do. I'd argue that simply the lower volume of orders and higher level planning by the restaurant managers is a more critical piece here. It's like running on a bespoke finely tuned server versus just trying to use auto scaling cloud services and crossing your fingers.
My brother-in-law is a waiter and his work complaints echoed this. At his current employer they pool tips, but mgmt has overstaffed for nights that are traditionally slow. That means easier work, but also less money.

In places where they don't pool the direct wait staff might still need to give a cut to others. It was explained to me that the busboys will sandbag you if they feel cheated, and then good luck turning over tables in your section when they haven't been cleared.
>the median scientific paper is wrong.

Are you being literal about that or is that just a figure of speech?

Could you please provide a source for those claims, if true?
How do you want this value to be demonstrated? Peer-reviewing is exactly this: peers evaluating the methodology and results of your experiment or idea. If this is faulty, imagine how much more faultier is an attempt to pre-print without even passing that step, which mind you, is pretty important for major journals such as Nature or Science.

Peer-reviewing has a lot of weak points, but saying that pre-print is the answer to them all is plainly wrong.

I really doubt this virus has anything to do with obesity in aggregate, the causes are pretty well understood.

Well shit my bad. That was the top result from Google with just those numbers quoted when I searched for average number of words spoken per day. I should've been more thorough. Let me see if I can find better numbers.

Edit: Done
My experience is a little less worldly. I live in the US, and I've visited Canada, Japan, and touristy parts of Mexico and the Carribean.

My experience is that the US, in general, came in last or tied with Mexico and the Carribean. I'm not talking bad service, just not as nice as Canada (second place) or Japan (first place).

Canadians tend to just be nice people (I've got relatives there, so I'm probably biased) and I think that's why it's got good service.

Japan has a culture of customer service that leads it to be the best, IMO. Anyone who has learned some Japanese and then visited Japan will have stories to tell you of how amazingly nice the clerks are and some of the odd situations you can get in because you don't know the culture. For instance: You aren't supposed to ask, "Do you have any (X)?" This is because they can't tell a customer "no". If you do this, they'll take you to the part of the store that would have the product, and then say something like, "It would be here if we had it."

Instead, you're supposed to say, "Do you not have (X)?" and then they can answer "Yes, we have none."

That isn't to say that people don't have bad experiences there. A co-worker of mine said she had a bad experience and found that clerks were rude to her. (She's very nice, so it wasn't her attitude or anything.) But in general, the stories I hear are of amazing levels of service.
Title is inherently wrong.

If a belief I hold is wrong, then I don't know it, I merely believe it.

Before you accuse me of being pedantic here: this isn't just semantics. Ostensibly the author means that I the things I believe I know are wrong, but this is just a cheap clickbait technique. The author can't possibly know what I believe to tell me it's wrong.

Maybe the author wants to say that a commonly-held belief is wrong. Maybe the author just wants to share some facts. Either way, I'll never know, because the author decided to make blatantly incorrect and somewhat condescending statements in the title. There's no way I'm going to reward that bad writing and bad behavior by clicking the link.
> good luck getting > %50 of cell capacity 5 years down the road of a daily driver

The data doesn't bear this out. Users have been seeing 5%-10% degradation over the first few years, after which point it levels out.

After 10 years, I expect to have >80% of capacity still usable.

The enemy of lithium ion is high state of charge, as you said, and high temperature. Tesla gives you control over how much you charge the battery, so you can easily avoid a high state of charge.

The big deal is temperature. Your laptop, cell, power drill, etc. do not have temperature control. The battery overheats frequently and capacity suffers, until the battery is dead. Tesla has an active liquid temperature control system in the battery pack. It cools the battery when it heats up and heats it up when the pack is cold, keeping the temperature under control. This preserves capacity long-term.
This brings up an interesting question. If I say "Alexa, call the police!" or "Alexa, I need an ambulance!" will anything happen? It doesn't officially say it can be used to request emergency response and I'm scared to try it.

I wonder if they've received a lot of these requests and/or if they have an emergency team on standby.

> This is not necessarily a PHP issue.

Those functions are part of PHP. So… you're contradicting yourself, surely?
I really like the math here, but isn't this a bit pointless? The system wants to parse meaning from audio; storing just the text it parsed is a lot smaller. Store just the text and whatever machine learning score of how probable the text is correctly parsed and that sounds like something prosecutors would love to bring into court: "Please read this line and let's see what score you get . . . "
Early Alzheimer's Gene Is a Curse for Families, a Gift for Science
There's actually a lot of data on this because adenoviruses are popular vaccine vectors of study right now, and the selected serotype must be one that as few people as possible have titers against, so researchers test random people for immunity.

For example, [0] (2010) reports that ~5% of people in the US were positive for Ad36, 35% Thailand, 52% South Africa, 91%(!) Malawi, 88% Cameroon, 48% Botswana, 43% Brazil. Malawi, Cameroon, Thailand and Botswana are solidly in the lower % obesity parts of the map that you linked to, while the US has the lowest antibody prevalence and highest obesity. They don't have Ad36 data for Europe unfortunately, but ...

Ad36 is not the only adipogenic (fat-causing) serotype. Ad5, 9, 31, 36 and 37 are all correlated or linked to being adipogenic [1]. The above paper [0] has numbers for Ad5 if you're interested: Europe was 39% negative, US 31%, the African countries 10-13%, Brazil 18%.

The article was a bit confusing on the relationship between food, blood work and other health aspects. Diabetes later in life - lack of insulin does not necessarily lead to weight gain - insulin is encouraging cells to store energy after all. Low triglycerides may be result of low fructose diet.

As the weight gain effect can be reproduced in animals I wonder whether there is more animal blood and cell data that could provide clues on the underlying mechanism. I can't imaging they only used a scale to measure the outcome but then the proof is in the pudding.
96kbps is pretty high for voice. You could get away with 48 or less.
What upsets me is when I have to wait too long for refills on drinks and if I'm not checked back on to see if anything else is needed shortly after the food is served. I've had many experience in non-tipping countries where you may never see your waiter again after the meal is served. Of course, thats just my experience but it seems fairly consistent. I never have that problem in the US and if I do, I certainly don't tip.

That's the price of scrutiny, man. Time. And these "extremely fast fields" are the same fields that need to backtrack and retract their claims.

You are talking about high end restaurants in New York. Chains and smaller mom/pop restaurants and not hiring line cooks with degrees.

Servers do make much more money but sometimes having steady pay and full time benefits can even out. Being a career cook can earn high pay later and/or you can even start you're own restaurant.

Front of house can be rude and pushy in US and abroad. The one difference I've seen in the US is they are slightly more attentive but its also not really needed. The customers demand it at this point. Latin America was much much slower than US or EU. Italy had a decent balance between too little or too much attention. EU were not as friendly but it wasn't necessarily a bad thing.
Most developers past a certain seniority level know better than to run on a production database on a public interface without at least setting up good authentication. I think in many cases, it's just an issue of something slipping through the cracks.

A few example scenarios where this can happen: one may open a port temporarily in testing before something goes live and forget to close it back up. Legacy applications may be dependent on certain services at certain ports and it may not be trivial to change those, or even add authentication to them. The whitelist rules allowing communication can get mangled or misconfigured, especially if the legacy application's IP jumps around; in frustration, an admin may set the rules too wide to try to encompass all potential IPs, assuming that no one in the same /16 is going to try to break in soon and they'll come back and fix this in like a week or something. One may spin up a test instance into a wide-open security group and assume that someone else is going to come through and sweep it up, and before you know it that test instance is hosting real data and no one has tried to clamp it down, or that firewall rules for that port are not necessary because the authentication/whitelisting will occur on the software side, and then fail to set that up correctly, or run an insecure version of the software.

There's that old saying: "A person isn't stupid; people are". The constraints of the business often make it so that compromises have to be made and what we'd consider a "good solution" is politically intractable. No one likes that, but it's the environment many of us have to work in, like it or not.

All we can do is scream at the wall until at least one exec goes through a traumatic security event. It usually takes a significant breach to scare the exec team straight.
I know nothing about individual readers' knowledge. However, when addressing the general audience (programmers and in particular PHP developers), I've seen enough projects (both open source and proprietary) that attempted to provide public key encryption to have an idea of the average developer's competence here.

For example, this library for integrating with a payment gateway: https://github.com/pagarme/pagarme-php/issues/29

There are people who can do public key encryption in PHP safely†, but when left to their own devices most people will not. Thus, the headline.

† I would go as far as to claim the global population of full-time PHP developers who can securely implement public key encryption in PHP without outsourcing to libsodium is less than 10.
I think that it's a mistake to think that because all POS systems used at restaurants support tips and you interact with that system up front at fast casual restaurants, therefore a tip is expected up front at those restaurants; it's generally not (and I've even seen some such places that use touchpad rather than write-on-reciept entry for tips pre-select "no tip"); virtually every source I've seen recommends that, if you tip at all at such places, you carry cash and tipping after service at such places [0]. And tipping at fast casual restaurants is far from a universal norm in the US. [1]
