In the US, credit card transactions are reversed in case of fraud (no questions asked, super easy), but if someone lifts your pin and empties your bank account over debit, you’re on your own. This actually makes it more dangerous to use debit vs running it as credit.

Also while you don’t want to take on debt you can’t pay, there’s nothing too complex about debt and credit. Businesses all largely do their accounting like that, and if you really zoom out, all money is a system of debt and credit: the $20 note in my pocket is credit from my company, since I gave them my labor, they owed me. My company in turn was owed by one of its customers for services my company offered. The customer might have gotten money from their company, and so on.
I wonder why this isn't standard service from every credit card provider, ideally as an app.

It would make the CC numbers from database leaks a less valuable target since users could easily compartmentalize for every transaction.
I'm giving a Pony workshop at ICFP this year (https://icfp18.sigplan.org/event/icfp-2018-tutorials-writing...), this repo represents the material that I'll be covering. I've given early versions of it twice in NYC. I think it kind of works as a stand-alone thing (but you miss the thrill of hearing my voice and asking questions).

I'd love to get some feedback if anybody has any thoughts.
Minor nit: I wish the "With great data come great neural networks" graph in the blog post had data points from real experiments instead of the hand-wavy curves that are drawn. I know the goal is to give intuition about DNNs v. classical methods, but I don't think I've ever seen a version of this graph with real data! I doubt the real curve would be infinitely differentiable like the ones plotted :P.

>> Neural networks have recently met success because of the rise and availability of large amounts of data.

I think that the improvement in computation power has had at least as much of an impact on the field as data! The only reason people have even bothered to collect the amount of data they have is because the DNNs that need the data are finally cost effective to run on modern hardware.
First of all some of us use RSS just fine. And RSS is in fact still mainstream, at least for podcasts.

I don't use Firefox's live bookmarks. That's not what bothers me. What bothers me is that Firefox has a "Subscribe to RSS" button and you can register your own RSS Reader such that Firefox can directly subscribe your RSS Reader when it finds a RSS link in the page's HTML. I hope that doesn't go away and right now I'm assuming that it does.

And to contradict you ... no, it's in no way understandable. I understood many choices from Mozilla, even their integration of Pocket which I like, or their integration of DRM, which I assume they had no choice in the matter. But not this.

If popularity is an actual argument, with complete disregard for that percentage of users that cares about RSS, then we should just switch to Chrome. Chrome has an extension in its app store btw that does what I want. I might as well switch to Chrome now and be done with it.

Mozilla would do well to appeal to the long tail, they can't afford not to.
Founder of gigalixir here. We use GCP under the covers by default, but you can also choose to use AWS if you like. You can also choose which region you want to run in, but we only support us-east1 and us-west2, and on GCP: us-central1 and europe-west1.
I personally prefer the more concise version :)
In the comparison with Ethereum: invoking a smart contract function does not require value transfer beyond gas (transaction cost). Most such calls carry no ether attached, this is how it's supposed to be.
These are already at airports, since cash can't be accepted.

If there are any Apple Music engineers reading this: My wife and I changed our Apple ID country/region a few weeks ago. Without warning, we both lost our entire Apple Music library.

I’m a little surprised that a service with 40M subscribers doesn’t seem to consider that users might do this.
>there will probably be an extension that does that

And then another draconian compatibility-breaking change to the extensions APIs will permanently disable said extension a year later...

I love Apple Music - the ability to control my music through Siri, add songs to playlists via Siri, and I really have no problem finding what I'm looking for in the catalog or via curated playlists. Also, my stations have become pretty customized at this point, so I hardly ever have to hunt for music to listen to.
Founder of gigalixir here. You're right, but I just wanted to mention that those limitations are for the free tier. Once you upgrade to the standard tier, both those limitations go away.
Spotify is great, I couldn't care less about Apple Music, but you know what is really awesome and I didn't see anyone mentioning it...

Get on Premium so you don't have to listen to ads, and it is just amazing. I paid initially so my kids would not be exposed to commercials, but I really love it and most of the time it is the most convenient because it is always there.

I marked few playlist I like for commute and roadtrips to be downloaded, so it works offline.
What I really want is it to be built into the browser so I don't have to use a library at all for the things React/Vue/Angular do.
I use gigalixir.com, but I'm also the founder so I'm biased =)
My interpretation of a similar scenario (my girlfriend and I both followed & listened to each other's Discover Weekly) was that Spotify noticed that traffic and started assuming our tastes were converging (they were).
While I agree that it's not "in good taste" to recommend your own book like this. I feel your reaction is a bit harsh and did not consider that he actually gave disclosure upon recommending the book.
True, but AFAIR only for live Beats Radio. I think to play shows later you need a subscription.
The middle would trade X deaths for X case of pain and wasteful spending which is not a fair trade.

Trading 5-100 of your fathers cases for 1 life is IMO a worthwhile trade as we want a system heavily biased toward savings extra lives.

PS: It's the rate of false positives vs saved lives that cause wasted treatments not the number of tests.

>In a model where Bitcoin is the only available currency, you could certainly assign an economic value to a mixer - the value of the created privacy (yes, I know that mixers are flawed).

Are mixers spoofing?

Here, consider a market with three people: A, B, C all with 100 BTC.

At 12:01 A sells 50 shares to B. Starting at 12:01 and going until 12:00 B and C sell 1 share back and forth, one transaction per minute. So after 24 hours they have:

A - 50

B - 150

C - 100

Is the 'true' trading volume for the day 50 or is it 1490? It's a matter of perspective but Elementus views that 50 as an important number that investors should have. I agree that using the term 'economic' is dumb but investors want to understand the actual dynamics of buyers and sellers in the market, not the dynamics of ultra-noisy zero-netting mixers.

Both that story and this one can be true.

It can recommend unconsidered, more effective treatments just as readily as it can recommend unconsidered, dangerous ones — particularly if the system was as extensively trained using MSK's physicians' preferred treatments, instead of (or even additionally to) actual clinical data as The Fine Article suggests.
All of the things that happen in a regular CC transaction have economic value, i.e. buying stuff, interest, loans, network charges, transaction fees etc. etc..

Even BTC-USD trades have economic value obviously.

The article presents transactions which are basically kinds of accounting functions, i.e. tumblers to hide trails etc. etc..

As far as USD, maybe this would be the equivalent of moving USD from one account to another.

Now, clearly it wouldn't be done if there was no value to the transaction ... but it's generally net neutral stuff.

There's now way to compare to the USD because it's generally not something that is tracked at all with fiat currency because it would be pointless. But it just happens to go on the record with BTC.

London Review of Books: On Obama “The Impermanence of Importance”
No, not a reasonable person, but a person inclined to fall for diet fads, i.e 90% of the general population. Counting calories is hard, and it's OK to come up with methods to make the effect of calorie restriction easier obtain by the general public.

What's not OK is to then proclaim "Calorie counting does not work". The nutrition gurus might understand that figuratively, "calorie counting is an impractical weight loss method for most people that lack the self discipline it requires long term".

But when the general public is exposed to these ideas, the takeaway is magical thinking, "bad" calories you cannot touch versus "good" calories that you can gorge on. It's something very satisfying to believe, it's a shortcut. It's not my fault and my choices, it's industry X that is making all of us fat. It's an "epidemic".
This is good enough for an example, but for a "real" web server, you wouldn't do this; you'd use a framework that handles a lot of this kind of thing for you. I think this code was adapted from the final chapter of the Rust book, which is mostly about learning how to write a simple thing than being production-ready.

It's still a product once you account for overheads. 200€ a year isn't "pay my AWS bills for me and get my work for free...", it's "pay what I think this product is worth."
Yes they are backed by the U.S. Government, the most powerful organization in the history of world civilization. They are a representation of a claim on wealth by the entity that holds a monopoly on the legal use of violence to compel people to accept said currency as a medium of exchange.

I have no objection to them selling a working technology but they knew Watson was pure snake oil and did it anyway. Same as Theranos.
Not just games; anything other than hypertexts and forms.

In those days there was no notion of SPA or other contemporary well-established patterns for online interaction.

I authored several commercial sites using Shockwave and the like and it enabled us to give clients the ability to author media-rich and design-heavy presentations in a fashion they were familiar with from card decks applications. At the time doing so in a 'sexy' way made them stand out.

It was a cul de sac, but it was a worthwhile direction to test in terms of UX.

That it was proprietary was weighted differently in those days. The world was dominated by closed standards and open source was still vestigial especially in commercial applications.
And he is right. Time dilation means it's impossible for them to form. (From the POV of me, here on earth.)
I am not 100% this is true. people want things narrowed down to as little text as possible, consider the fact that many people read headlines and stop there.

when talking to a writer i knew, he would always do this type of dress up with stories. to him, these were the important parts, not the big picture or raw data. it was part of 'the art form'.

There are other means of getting usage data than just telemetry. Depending on it when you know some percentage of your userbase has turned it off is disregarding those users completely.

At the same time, people disable telemetry because as we've come to understand much more clearly as a society (and some of us already knew long before "recently"), there is too much data floating around about us as it is. Not all of it stored in a secured, anonymized fashion even if the organization in question claims to. People are skeptical of automatic telemetry data collection for good reason.
You can build Android apps (and iOS too!) with Adobe AIR today. In fact, it's been possible since about 2010.
Man I hate analysis like these. At least yours isn't as flawed as that guy on reddit who didn't understand the difference between a Watt and a Joule (or kWhr), but what you did is still incredibly basic and ineffective. You aren't accounting for reddit simply frontloading the first page view, compared to old reddit reloading pages each link you click, or countless other possible optimizations.

Just measuring single page-loads using a browser extension is far to simplistic of a metric.

Nothing like being down a quarter of your value to shake things up.
Yep, exactly. The best diet is the one you will stick to. Everything else is secondary. If it's low carb or vegan or paleo or mediterranean great. If it's the Twinkie diet, not as great but whatever. Penn lost a ton of weight on the potato diet starter phase of his diet.

Personally, I lost 50 lbs through a combination of exercise plus homemade vegetable/fruit juice replacement of two meals --which would be high carb. Some people would not be able to deal with that so it wouldn't work for them.

… and the subsequent companies went on to be hundreds of times more valuable than Standard Oil alone …

Freeze one company and let another group run ahead for decades, and it is not surprising at all that after that much time, the companies that benefited from compound growth for that many years will be more valuable.

An important question is whether the subsequent companies went on to be more valuable than Standard Oil would have been. An even more important question is whether consumers were more satisfied with the Baby Oils than they would have been with Ma Oil.

Yes, in fact some recommendations at LW are odd:

"On analysis in Rn, orthonormal recommends Strichartz's The Way of Analysis over Rudin's Principles of Mathematical Analysis and Kolmogorov & Fomin's Introduction to Real Analysis."

Rudin or Kolmogorov & Fomin are waaaay more advanced than Strichartz. If they wanted a more conceptual but still advanced book they could recommend e.g. Hubbard & Hubbard which is a marvelous book IMHO. I'd put it on par with SICP and CTM in terms of the enormous amount of ground it covers and the insights a novel reader can get.
For Algebra, I'd rather recommend Aluffi's "Algebra Chapter 0". The prerequisites are maybe a passing knowledge of some algebra, but mostly start with fundamentals and develop the concepts through explanation and then interesting exercises. It's a joy to work through, but can occasionally be tough.

For Analysis, I'd rather recommend Tao's "Analysis I". Tao has the style that I really enjoy where he uses a mix of intuition and light mathematical maturity to build basic Analysis from first principles. Not everyone benefits from this approach, but if you're the person who enjoys discussing and debating with the author as you develop the fundamentals, then Tao's Analysis is fantastic.
From what I understand C-sections are much riskier for the mother than we might think. It's significant surgery which can always lead to complications or infection.

The other factor is delivering a child naturally that gets stuck and didn't get enough oxygen but lives is probably the most expensive outcome for doctors because that child can live with severe physical or mental handicaps and need support the rest of their lives.
Phosphorylated Tau may also play into the herpes story quite well. It regulates microtubule stability, and herpes viruses traffic on those microtubules to hop from one nueron to the next :

Congrats to the teams at Stripe for getting this out. This opens up a lot of potential for innovation with these kinds of cards. Well done!

Stripe and Twillio lower barriers to entry with products like this. This eliminates a powerful moat that other companies have built. Starting a digital bank or expense report software like Divvy are now much easier. What companies will be at greater risk because this is now an API?
That is really interesting to think about, however isn't a bunch of that going to be cached? IE the JS doesn't get loaded every page view, just the content.

And now I need to go down a rabbit hole to find out the cost / GB currently. I would expect that it has gone down in the last 6 years.

Multi-tenant is almost always my preference. Data can still be segregated per-client at that database level. Multi-tenancy with a solid session caching layer will allow you to horizontally scale as needed.

Multi-instance will require setting up new servers per client. Potentially increasing cognitive overhead of which servers are handling what. Definitely increasing costs, as each server will have idle CPU cycles that could have been used to serve up a smaller clients.
Cue a plethora of startups popping up where the main business model involves harvesting the transaction data via such cards. Probably most interesting for shopping sites since it gives you insight into all the transactions made with competitors (only just realized that that's probably why Amazon issues credit cards).

A nit: is it really true that C sections are primarily for high-risk pregnancies? C sections are at an all-time high. Both my kids were delivered by C section after attempts to induce labor, but those inductions were based simply on calendar due dates assigned early in the pregnancy. People schedule C sections in advance.

More importantly: anyone who has had a C section before is likely to deliver all future children via C section; it's not a requirement, but a normal birth after C section is a special arrangement.

Finally: C section itself is a traumatic surgery with long-lasting health effects for the mother. It's routine, but still a big deal.
At 10c/kWh that seems to imply an annual energy bill of ~$300MM just for the extra bandwidth?

A radio ad for the second season of the Duolingo podcast prompted me to check out the first season.

I appreciate the idea that the episodes are life stories instead of fake cafe scenes. The stories are interesting, and sometimes intense. The CEO / cofounder talks about a kidnapping in his family in the last episode of season one.

The small english summaries every few sentences helps provide context. That helps with context for the words I'm not familiar or strong with.

The language used is intermediate level. Personally I am below that level, but have gotten value from episodes.
Where do people still care about pushing the boundary, exploring new paradigms, and building shit? I'm so sick of hearing about this mythical "silicon valley of yore" where there was community, and fellowship, and a desire to improve humanity.

"It's just business" sounds like a justification, where you're trying to say it is okay, which may be where people are inferring that from- even if it was not intended

Even in your further explanations of your repeated use of the phrase, you continue to say things like "it's not corrupt, it's just business". That makes no sense. Something can be both. These are not the same thing. Business is not always corrupt, and corruption isn't always "just business"

A view that "much of business is corrupt" may be true but there is no nuance in your (confusing) statements.
