> The last time I got new glasses (a few months ago), the cheapest pair of frames in the shop was $450.

People need to avoid Luxottica's retailers. That price is absurd. The insurance isn't saving you a dime, the amount you're paying after insurance "savings" is likely higher than you would pay outright elsewhere.

In other countries that I've lived (where you pay cash, no insurance) frames top out at $150~ equivalent (for branded/designer) and start under $30.
And we’ll be introducing a cool feature where we can show you the name of a person walking up to you, just in case you’ve met them before but you can’t quite remember whom they are.

There's quite a big difference in having a website "shut down" compared to deciding not to provide a given site/company/organization with services.

It's the digital equivalent to a No Shirt, No Shoes... No service sign.
To be brutally honest, I find it more condescending when people try to downplay the brutality and devastation colonialism enacted on the various native populations while trying to claim it was the victims of colonialism that were truly at fault.

Generally speaking, wiping out large amounts of any population whether intentional or not is probably going to have negative multigenerational effects.
Thanks. I bought some loose black tea from a shop in NYC's Chelsea Market last year. I figured I would be in for a treat, but it was completely bland and tasteless. Been hesitant to splurge much since then, but will definitely be checking these recommendations.

Well-said.

This makes me circle back again to the concept of "Minimum Viable Product." It's been said that as a startup, if you're not embarrassed when you ship v1, you waited too late. But what's often not looked at is "just how embarrassed is embarrassed enough?"

Going against the concept of launching an MVP is the idea of "you only get one chance to make a first impression." Which is why a number of founders started talking less about launching Minimum Viable Products, and more about launching Exceptional Viable Products.

Those few extra details can be crucial levers to determining your product's success with customers. Of course, the key is determining which of those key details are the ones you need to pay attention to, and which ones you can pass over for now.

Here's Rand Fishkin on MVP vs. EVP:

Right. But you own your blender. It's naïve to think you own your phone just because you carry it around.
The Vimes series is amazing... I think it's a bit above the Moist series but I absolutely love Raising Steam and, to a lesser extent, Making Money - because both characters are coming together. Still, I think my top pitch is somewhere within Night's Watch, Men at Arms & Jingo - I think Guards! Guards! is also quite good but Night's Watch did nearly everything Guards! Guards! did... but did it better.

Honestly, his books are just amazing though, quite worth a read.... possibly skipping to start at Equal Rites since The Colour of Magic and The Light Fantastic were less polished than his later works - but do check out the Tim Curry having movie covering those first two books... maybe bring a power point presentation or two along to appease any power hungry wizards though.
I was disappointed in this article. Based on the Hacker News title, I assumed that illegal cheetahs were causing the extinction of the ultra-rich. This is not the case, in fact, the reality is the opposite.
The HackerNews crowd will not be taken in by this copy; however, it will doubtless work on enterprise folks.
Amazon managed to somehow introduce more regular innovation cycles.

Siri was launched Feb/2010, Alexa (Echo) Nov/2014. 4 yrs advantage. Today Alexa is much better ecosystem.

Amazon Hardware looks promising..
You are missing something really important though. Those kind of claims usually start with the phrase, "If X continues at the current rate..."

Just in the last few years we (in the U.S. at least) reached the lowest rates of smoking ever recorded, which surely accounts for the lower rate of deaths at least in part.

The CDC in the 90's couldn't have known how effective the aggressive campaign against smoking would end up being over the next 20 years. They had to make a prediction based on the rates of smoking they had at the time, and that's really all you can ever do.

Are you suggesting that we shouldn't try to predict anything because what if we're wrong?

"Eye"glasses which do nothing related to your eyes. At least Google Glass had a display.

Can I just have a display? Pretty please? Doesn't have to be high resolution, it doesn't have to have much intelligence other than connecting to my phone.

We just need magic-mirror-like glasses that don't look like you have been captured by a Borg cube.
> Medical schools/the AMA are artificially limiting the number of students and residents for their own ends (keeping wages and scarcity high) so they need to charge a lot...

That sounds like a strange conspiracy, do you have evidence to support that?

Keep in mind 20+ years ago that insurance was much cheaper, deductibles were almost nonexistent, and care networks were giant. Talk to your US parents or grandparents about their costs of health care, you'll still be stunned at how much cheaper it was. Medical schools and the AMA still existed then too BTW.
As I understand it even the 'paper' teabags contain plastic which is why they shouldn't ever be disposed with any organics waste (and possibly raise similar health concerns due to being immersed in boiling water before being ingested).

A quick search reveals an article[1] stating:

> Most bags, including those made by the five leading tea brands in the UK – PG Tips, Tetley, Twinings, Typhoo, and Yorkshire Tea – use non-biodegradable polypropylene as sealants in their bags. A spokesperson from the makers of Yorkshire Tea confirmed to Resource: “Our tea bag material contains around 25 per cent polypropylene (PP) which we believe is typical for the market. It’s a component of the material that allows us to heat seal the bag.”

You mean

ON u.id = c.user_id WHERE u.id = <...>

?

If the average user record includes a non-trivial amount of data and there are many comments, you're repeating a lot of information in the query results.

> What about the issues with lithium and coltan supply for batteries ?

Lithium is in large supply (Atomic Number 3, right, third place on the Periodic Table), and is easily recyclable from current batteries.

Cobalt is a miniscule portion of current battery compositions. Most battery companies have been working to minimize or remove it. It should be recyclable, but it's never been economically feasible to recycle it from current battery compositions because a) it is such a minority component of current batteries, and b) Cobalt is cheap. (Cobalt is a "waste product" or by-product of Nickel mining today. The threat to Cobalt supply is that most Nickel mines today are in politically questionable regimes such as Columbia and the Democratic Republic of the Congo. But Nickel mining is likely something that continues to happen regardless of politics.)

> What about the ~+33% increase required in electric power generation to replace oil in transportation ?

If every car on the road today switched to EV tomorrow, but made sure to charge only during the "bathtub" of off-peak (evening) hours, there's absolutely no increase in power generation needed. Our culture's day-time peak generation capability, which has to account for most of our industrial use, is more than sufficient so long as consumers are smart about when they charge.

(The difference between Peak demand during the day and off-peak evening hours really is huge. "Filling in the bathtub" that the off-peak hours create in the demand chart is considered something of a holy grail for decades in utility grid planning because it would mean more base load generation that doesn't have to shut down every night and can run more continuously/smoothly every day.)

Smart Grid solutions exist and are being planned where cars can even help solve demand problems by acting as sitting batteries (as owners allow them to) that utilities can "loan" power from a car during peak demands, and pay back with "interest" during off-peak (and potentially doing so at an incredibly granular level).

All of which is to say that there are already market solutions to the increased electricity consumption of EVs.
Peak rates might go up, perhaps, but the natural tendency of most EV owners is already to charge during off-peak (at home on the evenings), even without the extra incentives of big cost differentials between peak and off-peak utility rates. Most EVs today already have okay off-peak hours selection tools built-in, even without the detailed electricity price-sensitivity options that Smart Grids might eventually bring to the market. (But Smart Grids are certainly on utility road maps because there's a lot they could do with that extra demand sensitivity.)

I've yet to hear a worst case for EV electricity demand that would need 33% more capacity at Peak demand. That's an interesting and presumably unlikely scenario.
You are claiming that China is charging a price equivalent to US delivery but it isn't. It's charging a price equivalent part of US delivery which clearly a false comparison.

The cost for an individual shipper in the US versus the cost for an individual shipper in China is clearly the correct point of comparison and it seems NPR was in making that comparison.

Edit: removed comment about other thread.
I didn't say it would legally disqualify you, just that it would prevent you from doing jury duty properly.
I'm not sure what your point is. Time-series describes the data, not the database.

You can store timeseries data in Postgres if you want to (and optionally adding extensions like Timescale). You can store it in key/value like Redis or Cassandra. You can store it in bigtable. You can store it in MongoDB. Obviously different scenarios require different solutions.

KDB is a relational database with row and columnstore with features for time series and advanced numerical analytics along with a programming language. KDB is a thing because of those abilities, whether you use it for time-series data or not.

They have LineageOS builds with MicroG integrated that are technically a fork, mostly because they add permission API to spoof Google apps, that got rejected upstream. Also they ship with two location backends (Mozilla and Nominatim), though disabled by default, and FDroid comes preinstalled as a system app.

Show me a piece of code where you think you need locks I guess.

I will concede that I got the two terms confused, mostly because I haven’t had to think about this kind of stuff in years because there’s literally nothing I’ve ever had to do with JavaScript that’s required me to think about it.

But I’d really love to see some code where you can’t handle concurrently waiting coroutine priorities in a single threaded world. Concurrency without parallelism is not really a problem the way I see it.
Your comment:

" ... now my data can be harvested wherever I go instead of just in the privacy of my own home"

Two points:

1. How do you know what harvesting takes place?
2. IF it is occurring, how has the status quo changed?

The comment seem to make some strong assumptions about what these glasses are doing, without any substantiation.
I think part of the article's point is that private investors cannot be held responsible for their foolish because they cause "ripple effects" as externalities (eg: dismantling of a functioning taxi industry)
Where is this? I've never seen loose tea being cheaper. I mostly see loose tea being sold in premium tea stores, and their prices are exorbitant.
Please explain why this wouldn't be good form? A University's course requirements are publicly available.

My guess is that an entire course on Marxism wasn't actually required, and it was either an elective or a much smaller part of a required course.
I am amazed that this got green lighted.

It's what happens when a company has so much money it can make things without doing any actual market research.

Thats not what just happened. "You accuser" didnt accuse you of being a privacy violation.

Smart Phone was brought up as an EXAMPLE of having a microphone and camera in your pocket, connected to the internet. It wasnt a change in subject from tracking devices.

>Although you are clearly very confused, because whataboutism is a logical fallacy....

I believe you are the confused one. You changed the subject to a fallacy discussion, by mentioning whataboutism. Its like changing the conversation to fruit by mentioning bananas. Obviously banana is a fruit.

>By carrying a smartphone I'm not allowed to care about my privacy?

to quote you "instead of just in the privacy of my own home." no one said you arent allowed to be concerned about privacy, but thats not what you said. the "hivemind" disagreed with your PREMISE that you arent currently tracked and that this product would suddenly create tracking ability that doesnt already exist. Its the "instead of just in my home" part people are taking issue with, because the "just in my home" reality doesnt exist.
Stop getting sick and having to use the healthcare system. So no, not really, unless we change our living habits as a civilization, but then we get old anyway.
I feel you are not taking into account the importance of "unless something changes". I see the publication date of this as being 1997. That was around the time when globally it started to be conceivable that restaurants and public areas and even bars could be areas that were smoke-free. Changing the norm seems to have lowered the number of smokers and thus smoking deaths.

You scoff at these projections but I feel that turning your energy a bit and focusing it at how these projections indeed were used to good effect would get you closer to the truth than what appears to be your assumption that nothing was done and the projections were false. So much has changed in the intervening 22 years.

I’m a little skeptical. The example in the post, where you validate a URL against a regex before string-interpolating it into an HTML fragment, is essentially an anti-pattern. It’s too easy to screw up the regex and end up with an injection vector, especially in cases (probably the majority of them) where the thing being validated is less inherently constrained than “alphanumeric”. Instead, it’s best to use APIs that are safe by construction - in this case, using DOM APIs to create elements, without ever going through the intermediate string representation of HTML. See also, “Never sanitize your inputs!”:

http://blog.hackensplat.com/2013/09/never-sanitize-your-inpu...

But if you use DOM APIs for everything, this “Trusted Types” API seems largely unnecessary. It would be enough to expose a switch to disable innerHTML and similar APIs entirely.

On the other hand, DOM APIs are rather unergonomic to use raw. Many wrappers exist, but React‘s JSX takes the cake by letting you write code that looks like string interpolation, yet compiles down to type-safe node creation. (Kind of like what parameterized queries do for SQL.) If we’re looking at browser-based approaches to solving XSS… how about standardizing something like JSX as a built-in browser feature? That way it could be used by everyone, even those who want to minimize dependencies or code directly for the browser.

(Yes, I know it’s been tried before, in the form of E4X. But that was a very different era…)

I am wearing a Garmin FR945 right now; in fact, I sold my Apple Watch 4 a month back, after it sat on my nightstand for months following my purchase of the 945. I previously had an Apple Watch 2.

The AW might be a huge step down for your purposes, but I was fine recording 5+ hour bike rides and my 4+ hour (yeah, yeah) first marathon. I really disliked using a touch screen on the AW for recording runs, particularly intervals. I love the feature set of the 945 and haven't looked back.

THAT SAID, I would trust the Apple Watch over the Garmin any day of the week for 'lifesaving' type tech. Garmin's software is spotty, to say the least. First off, I can trigger the Garmin crash detection at will by jolting to a sudden stop on my bike and hopping off. Not all that aggressively -- it happens in my normal dismount process with some regularity. I have to tell it to cancel the emergency call.

Right now it's setup to text my wife. Looking at the config, it says "Select up to 3 people to be notified via text message and email if an incident occurs or assistance is needed". I don't know how I could set it up to call 911 if I wanted to.

And that would all assume it even works. Multiple times a week, my watch says it doesn't have connection with my iPhone X, and I have to reboot the watch for it to find my phone again. My wife's FR235+iPhone 7 setup seems more reliable, but at least once a month for the past 3-4 years, it's decided to stop syncing and we need to reboot the watch again.

IME, the Apple Watch <-> iPhone BT connection just works. All the time.
Definitely. If it's harvesting data exclusively for my own use, then it's working for me rather than against me, or at least rather than treating me as merely a vessel from which to collect data.

Devices such as these and "smart speakers" are sold at a loss because their lifetime value to the vendor is in gathering and analyzing data. They are attacked more emphatically than smart phones by privacy enthusiasts because they are so grossly unbalanced when comparing end-user value versus their cynical treatment of users' data interests. A smart phone can have its "smart agent" features disabled and remain a highly valuable device to its user. But if you take away the smart agent feature from these more recent "smart" devices and you're left with an inert brick.
Well, for one thing, the employers get to use pre tax money (up to a limit) for their spending while individuals have to use post tax money, so it would be at least 30% less.

> reductio ad absurdum

Wow. Nice misapplication of a logical fallacy. My claim was that forging connections between legacy students and merit students was not particularly beneficial to merit students. You then claimed that this would lead to the supposedly absurd conclusion that your MIT education is valueless.

You cannot apply reductio ad absurdum here, because you cannot conclude 'an MIT education is valueless' from my claim that 'merit students do not need to be friends with legacy students to succeed'. Since MIT does not have legacy admissions, my claim does not apply to it. You cannot conclude anything about MIT from my claim. Nowhere have I claimed anything about college friends / connections in general, only those between legacy and merit students, which, again, do not exist at MIT.

Moreover, you have committed the fallacy of petitio principii (popularly known as 'begging the question' -- you don't need to go to MIT to have an understanding of grade school logic). You have already concluded that your MIT education is worthwhile (and perhaps it is, I don't know; you certain have not proven it), and have used that to mistakenly conclude that you could apply reductio ad absurdum to my claim which -- again -- does not apply to MIT in any way whatsoever.

So, we see that you've (1) misapplied a logical fallacy, (2) attempted to argue against a strawmanned version of my claim, and (3) used petitio principii in an attempt to persuade everyone of the value of an MIT education.

I did not downvote you, but I am unsurprised that you were downvoted.
Deductibles are weird. If you have kids, or are on medications, you don't think much about it, because you are in and out paying co-pays $25 here, $50 there, $100 somewhere else, and that boils the frog quickly.

If you are healthy and single, and have to get anything beyond a physical done, you get slammed paying the whole shebang out of pocket because you haven't put any money towards your deductible all year.

The greatest thing in health care over the past decade has been the explosion in Convenient MD urgent care centers and the like. It makes getting checked up when something needs to get checked up about as easy as going to Jiffy Lube, which is miles better than going to an ER or trying to thread the needle through the schedule for an appointment at your PCP.
You stick it on a little nub. Basically as easy as taking it off, assuming you sleep in the same place every night.
I shudder at the thought of my chronically late friends having kids and exacerbating their already borderline intolerable chronic lateness.
