Sure, but that's expiration, not invalidation, ie. we're talking about the ability to declare "this particular token is invalid now".

Incidentally, this limitation isn't too surprising to me... Is there any possible token-based authentication scheme that is both stateless (ie. no round trip to the database on every call) AND invalidate-able? Seems like any form of invalidation would require storing the "is valid" state somewhere else...
You're correct: I misread the piece.

>he claims that they conflate "practice" with "deliberate practice" and therefore didn't debunk him.

This seems unfalsifiable since we don't (and presumably he doesn't) have theories about either talent or intentions which might distinguish the two cases.

Myself I practiced the piano very deliberately in my late twenties and it didn't lead to improvement. In fact it lead to RSI. However, in overcoming the RSI I learnt about what talent means (inexplicitly, I'm afraid, so I can't explain it yet). Hence my claim that it is singular across all disciplines. This includes purely intellectual skill which, following Michael Polanyi, can be thought of as a connoisseurship of ideas.

Try this. Choose a lecture. As you go through it, create a bulleted list of things you don't know. A Google Doc works well.

Then go through the bulleted list in order. During this process, you will also encounter things you don't know. Add these to the top of the list and start from the top anew. As you work through bulleted items, mark them off or move them to a "complete" list.

What you are creating is a list of things you need to understand in the order you need to understand them. It guides your investigation and makes it all more manageable.

Bonus: Beneath the list, create an in-order set of notes pertaining to the items on your list. This is like a personalized set of lecture notes.

Based on the decline of Amazon UPS deliveries over the past couple years, UPS is becoming less and less important to them. For a while, Ontrac was doing most of my Amazon deliveries, but more recently, Amazon's own delivery service has been delivering most of my orders (not sure if they are really Amazon drivers or if they are contractors). UPS is still doing some deliveries (seems to be only products that aren't available in nearby warehouses), but not nearly as many as they used to. When Amazon first started using Ontrac, Ontrac's delivery service was so horrible that I think Amazon did it only so they could squeeze more money from UPS and Fedex, though Ontrac has improved a lot since then.

Recently Amazon has starting using the USPS to deliver more packages (or at least the last-mile delivery), and that service has been disappointing, I can usually count on a USPS package being delivered at least a day late, and more than once, it hasn't shown up at all, despite being marked as "delivered at front door".

In any case, while I would think that any unhappiness between UPS and Amazon would be resolved through their contracts, I doubt that UPS wants to rock the boat with Amazon, because even a small piece of the Amazon delivery pie is a lot of deliveries. So in this case, where workers health and safety is in question, it's good that the government stepped in to prevent UPS's desire to keep a customer happy from getting in the way of their worker's welfare.

> Why should have to install another app just to make checkout easier?

You shouldn't. Credit cards are broken. From the user perspective Apple Pay is just as broken (you need to buy an iPhone/Mac and fiddle with both of them). From the merchant/bank perspective it may or may not help fraud rates but as a consumer I don't care unless they start offering discounts.

> You're sacrificing security for convenience when you can have both.

I'm sacrificing the bank/merchant's security (worth $0 to me) in order to gain convenience for myself. If they want me to jump through hoops like this Apple Pay thing to prove I'm not a fraudster they should give me a discount.

Sound is a non-traditional way of moving data?!
I've been working on something similar[1] for a few years. Don't forget that you can use tun/tap devices to avoid re-implementing TCP/IP, and to gain interoperability with OS services!

Current Apple Pay works with subscriptions, I don't see why this would not.
This is exceedingly cool.

If someone wants to play with lower bandwidth data (text, basic file transfer) over sound, it's a pretty active area in the world of amateur radio. You can download the open-source program fldigi (http://www.w1hkj.com/modes/index.htm) on 2 computers, point speakers and microphones at each other, and try sending text (or files/images). The "flmsg" program will send pre-formatted stanzas which get converted into standard forms.

That being said, doing things like TCP/IP and other data is rather difficult on radio, mainly due to the duplex requirements and frequency spacing. But in pure audio, much more possible.

This must be why I always Uber to the airport. On normal days (not big travel day like Thanksgiving time) you can get from SoMa to Standing Outside SFO With Luggage Out of Trunk in about 30min during the day. I've seen as low as 15min at night.

I may have always gotten lucky and when I actually plan the trip I try to go for more like 45min travel-to-airport-time. Just to be sure.

On Thanksgiving or such, the off-ramp from 101 to SFO takes about an hour. That's crazy.

DRAM does not have 1ns latency! On a 4ghz skylake chip you can access the L1 cache at 1ns. DRAM is going to be more in the range of 60(local)-100(remote) nanoseconds. Optane will likely be > 300ns latency from what I've heard, if you access it directly through the CPU memory controller via loads and stores, which is still very impressive.
I imagine we'll see less of this going forward, as Amazon moves towards local warehouses and Amazon Prime Now one-hour delivery, in lieu of shipping everything by air using UPS/FedEx.

Non-traditional in the sense that I can't immediately transport data over my sound card with <sys/socket.h>
You can't bribe open source.

I find it hard to believe that a modern identity infrastructure (which we don't have, admittedly) combined with basic cryptography can't get us where we need to be.

We might not be able to cryptographically prove anonymity, but all it takes is trusting the government to anonymize the data correctly and make it secure in transport.
They also have a contest for proving secure, have they won the contest?
The point of using a stateless token is that you don't have to hit a central server / service to verify each token. If you need to do that in order to check for revoked tokens (for each request) then that defeats the purpose. At that point you may as well just check the original token / key for validity.

The difference in speed between checking for a token in the big pool (all tokens) vs the small pool (revoked tokens) should be a lot smaller than the round trip to token server (i.e. network cost).

Also, you should be able to easily store millions of tokens on a single server (something like Redis). Do you really have a site that has multiple millions of people logged in?

Also from the likes of your pet feature wishlist I'm not sure you are making an informed critique. Apple has withdrawn from the Vulkan group and put serious effort into its own graphics API, Metal. While you may not like that decision, it's no indication of low engineering investment.
At least in the discussions area, there is a distinct lack of "hacker culture" opinion expressed on any topic, given the name of the forum. At least from where I am standing, this reflects very poorly on ycombinator, and the "Tech Culture" that they are putting investors in touch with.

For a certain portion of the readership, Microsoft can do no wrong ... and when they do wrong, it's never their fault.

Perhaps the site should be renamed to "Young Upwardly Mobile Professionals with Rose Coloured Glasses and No Clue, Living in an Artificially Inflated 1st World Bubble News" would be a more accurate title.

This acquisition makes perfect sense for anyone who thinks that "the real economy" is in great shape, and middle management jobs are likely to experience unheard of growth over the next few years. Layoff numbers are just made up propaganda, and everyone around the world loves the US Dollar.

When this level of backslapping groupthink starts to predominate, its a pretty sure sign that things are rotten in Denmark, and should be a clear warning sign for smart investors in this market. But .... each to their own, its their money they are gambling with I suppose. (or conversely, other people's retirement hopes that they are gambling with)

Anyway, I find it interesting that Linkedin's infrastructure is written in a mashup of Java, Scala, Ruby, and God knows what else.

"The liquid leaked from a one-gallon container of “Amazing Liquid Fire,” a drain cleaner, during a flight from Louisville, Ky. to Boulder, Colo. ... The FAA alleged that the shipment was not properly packaged, was not accompanied by a proper declaration stating the hazardous nature of its contents." 9 employees injured.

"Amazing Liquid Fire" is concentrated sulfuric acid. Amazon review: "It eats through everything except plastic and porcelain. When you use this you have to be careful when you pour it down the drain it ate through the metal ring around the drain hole..... Unfortunately it did not unclog my drains, guess I have to call a plumber."

MSDS info: Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact (irritant, corrosive), of ingestion, of inhalation. Liquid or spray mist may produce tissue damage particularly on mucous membranes of eyes, mouth and
respiratory tract. Skin contact may produce burns. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by coughing, choking, or shortness of breath. Severe over-exposure can result in death. Inflammation of
the eye is characterized by redness, watering, and itching....

Also, sulfuric acid in contact with a long list of other chemicals is explosive.

"Amazing Liquid Fire" ships in a 1 gallon plastic jug. You can't even ship that via UPS Ground. Above 500ml, you have to use hazardous material freight.

Come on, Amazon, you have databases. You should know which products are hazardous. If the vendor can't give you an MSDS for it, maybe you shouldn't be shipping it.

I keep a counter in the JWT to at least mostly get around this issue. When processing a request, the counter is checked for the user, which isn't a big deal since all of the requests already require looking up the user. A counter increment invalidates all of that user's existing tokens.

If a user changes their password, their roles change, etc, then the counter gets incremented so all tokens issued up to that point won't be valid anymore.

> Underground farming in arid regions seems like the best scope for something like this.

This sort of mediated growing environment seems quite interesting as an approach to managing agriculture as environmental changes from global warming progress. In some areas, perhaps conventional greenhouses would suffice alone. But in others, underground agriculture might provide an additional buffer against climate changes. This would allow normalization of growing conditions in regions where the climate has drifted and/or become unpredictable in ways that would severely damage agricultural output.

Yeah, haptic feedback is challenging. The thing that gets challenging in my opinion with 3rd party haptic sensors is a low latency integration. Also, there are no hardware standards that define performance/latency requirements for a good AR experience. All those things will contribute to designing haptic devices.

I saw a paper recently http://aut.researchgateway.ac.nz/handle/10292/9652 around a low cost haptic game controller, which interested me a lot. There might be clever ways to create alternate haptic feedback like hot or cold sensations when an object is grabbed or interacted with (https://www.sciencedaily.com/releases/2015/11/151110082541.h...).

Because AR itself is not mainstream yet, it is quite hard to figure out what is the right haptic feedback that feels natural. I am hoping this will evolve.

I don't know that paper, but that's similar to what's going in Abbrase. It shows the best-scored mnemonic using bigram and frequency heuristics, but you could show more alernatives to let users choose their own mnemonic.

You can see multiple alternative mnemonics using `abbrase.py -m` -- it hasn't been implemented in the web version yet. It does give better results, from "wave several ominous silence" (default based on heuristic score) to "waves sever ominous silk" or "wavy seven omitted silver" (human-chosen mnemonics).
