Khan is pretty awesome. I'm using it "flipped" with my kids-- they watch a video and do a problem set, and then we talk about it. Mastery challenges figure out whether things are actually retained. They're motivated to earn energy points and avatars. (They should have more rewards, though, because they're running out of things to look forward to).

My middle kid just did two years of math in 4-5 weeks. Now we're free to talk about fun math stuff.
Agreed. Poor controls. You can actually drag and drop to place pieces, and clicking on an existing piece removes it, so the instructions should just be modified to say this.
They didn't roll anything back. That ledger, with the loss, exists today unchanged.

What did happen was a superset of users decided to create a new ledger to run in parallel, containing transactions up until but not including the loss.

The market determined the new ledger to be more valuable

I regularly call out bikes who don’t give the right of way to pedestrians in the crosswalk.

That said, unless someone is already frail being hit by a bike is nothing like being hit by a car. I’ve had two red-light running bicyclists crash in to me (once while biking, once while skateboarding). I’ve also been in three separate cars that got rear-ended (none of those times was I driving). The level of pain is an order of magnitude different.
So name aside, this would work with any compliant Webrtc provider?

I think @Nextgrid hit the nail on the head. If you're being brought in to use a customer specified stack/platform, you're just contract labor. That makes you a commodity, and you're likely to draw commodity compensation for same. Your goal should be to position your self as somebody who is qualified - no, uniquely qualified - to solve a problem for the customer. Get yourself in that position, and you'll be the one dictating the technical details of the solution, and you'll be able to charge more.
I guess you're right that TraceMonkey was announced before Chrome was released on 2007-09-02, one day after its inadvertent public announcement. TraceMonkey was announced, though incomplete, more than a week earlier, 2008-08-23: https://brendaneich.com/2008/08/tracemonkey-javascript-light.... SFX, however, was announced later, 2008-09-18.

I don't want to piss too much on SunSpider, but unsurprisingly V8 did better on V8’s benchmarks, while SFX and TM did better on SunSpider, once they were eventually released. That's because V8 was written to do well on its benchmarks, presumably, not because the benchmarks were rigged. Certainly they were in accordance with my experience at the time.

When Chrome was released, V8 was way ahead of the other browser JS engines at JS performance, partly because it had the first JS JIT. But the other browsers took a year or two to catch up, which they had because it also took websites a few years to move most of their functionality into browser JS.

I don't know why you keep emphasizing this “real-world” thing. Are you saying you think nbody and fannkuch are especially realistic benchmarks?

You're right though that Tamarin was a JS engine, not just an AS engine. We regret the error.

Every single crypto that has tried to pass that limitation has remained centralised in one way or another. You can either:

1) have centralisation

2) assume storage space will expand exponentially since the entire point of bitcoin is many many copies of its ledger

3) come up with a new method more secure than PoW but still decentralised

Good luck with (3). (1) and (2) are not good choices. So they moved it off the chain into lightning network.
My point wasn't that all SAAS business are going to be in trouble, rather than the growth equity is going to be impacted because they are funding only SAAS businesses. There is no hedging and as such, once business stop paying for certain SAAS services, they will in turn stop paying for others and so on and so on.
Membrane [1] is a project that aims to create a pipeline-based media framework, much like GStreamer, but more to the point (smaller scope) and written for the Erlang VM. We could foresee a WebRTC module existing at some point in the future, but right now the project seems to be just in its infancy.

I found it while dreaming about writing an Erlang-based WebRTC media server like Kurento, for which this kind of frameworks are invaluable, and currently GStreamer is the king.

They raised over $300 million and I don't know their profits.

Like one or two other of these firms, they basically pivoted to corporate training which has long been a reasonable if hardly breakout business. That's where Coursera (and I believe Udemy is) is today. It's not the disrupt education MOOC idea that was the original plan though.
Bitcoin is for wealthy Chinese people to evade currency controls and get their wealth out to politically safer countries. Buy mining hardware and electricity with Renminbi, get Bitcoins, sell in a foreign country for hard currency.
Yeah makes sense. Coursera isn't actually a disruption of education.

This post starts off with 'programming is a basic human skill' then lists barriers for success.

Programming is for everyone. There is a reason this planet has both 10 year old and 84 year old developers. We should view programming the way we view using tools or speaking a language. It should be accessible for everyone but a high-skill ceiling to do it really well.

I expect more from someone who works as an educator. Good teachers make average students great.

Am I wrong or isn't solving these issues basically the service UpToDate offers?
Why would someone agree to take out a loan with a 6% interest rate when the fed funds rate (not incl spread for various retail products etc) is 400+ bps lower. Even with the spread you are going to be paying less than that for a regular margin loan for trading, which is what I assume these loans are used for.

> I think the point your parent was trying to make is that the long term interest rate of any security has an upper bound of the growth rate of the economy.

This is incorrect. Economists won't need it explained, but you're probably not one. Think about it like this - the growth of the economy is a weighted average of the growth of many different assets. By definition, a few of them will have higher rates of growth a few will have lower rates of growth.

What you should've said is that the higher rate ones are typically higher risk. So at the lowest possible risk, you probably cap out at the economic growth rate (also not a truism, but somewhat closer).

If an advantage falls in the forest and nobody hears it, does it truly make a sound?

I'll grant those can be characteristics of cryptocurrencies, but they're only advantages to people who need those things. And they're only advantages on net if what goes with those characteristics ends up being net beneficial to somebody. E.g., the "inflation-proof" bit is a nice line, but most of the world had good reason for getting rid of fixed currencies after the collapse of Bretton Woods. And being "inflation-proof" implies a degree of value stability that Bitcoin most certainly does not have in practice.

I'll also grant that pseudo-anonymity and decentralization are useful to a very small set of people, but I think that's pretty well covered under the first part of my sentence. There are also some people who like those things for theoretical, quasi-religious reasons, but I don't think satisfying that counts as any sort of practical advantage.
I don’t know, I freak out just thinking at the depths of loss I’ll experience when my parents die. I’m aware enough by partially inspecting what they mean and do for me to have a hard time fathoming the total of that “calculation.”
While true, the "certain depth" you speak of is guaranteed to be below the 1" of the article's examples.

But it would be interesting how realistic it is to just excavate from your cellar into other territory. Considering quite a few bank heists have succeeded that way, it might well escape detection for a while.
It is expensive. We forward logs to spkunk (we run our own instances). Splunk is really solid. All the logs are json and require certain fields. We use it for tend analysis, alerting, graphs, reports, and digging into production issues. It digs through terabytes of data relatively quickly.
rewards increase performance for basic and mechanical skills.

But for complex skills, e.g. learning, they decrease intrinsic motivation, and thus performance.

Feels like a solution looking for a problem to me. Not only are phones trending away from being "phones" (rather portable internet terminals) but I'd wager the largest portion of smartphone use is content consumption, rather than content creation/collaboration.

Gotcha. That's difficult. What I recommend, then, is that you decide what your career goal is and bring that up as a long-term goal. In a lot of interviews, they'll ask you where you see yourself in 5 years, and people give whatever their answer is. I've found that the best thing to do is identify a particular role or person and say "I want that in 5 years." And then make sure that is a possibility (and believe them when they say it is!), and then ask about milestones.

Good luck. :)
The interactive whiteboard story I have:

My school system decided to introduce those interactive whiteboards into every classroom. Including the computer room. Where all the computers ran Linux or Solaris [1], which operating systems the software couldn't support. Without the computer to run it on, those things are worse than regular whiteboards since you can't even draw on them with real markers.

[1] Sun had yet to be bought by Oracle at that time.
Most people? Personal loan rates are closer to 7-8% on average I think. The fed funds rate is the very basic rate of economic activity. I mean, you obviously included the caveat about the spreads for retail products. What did you think those spreads looked like?

3.) Yes it is fully P2P. Even when going via TURN it is E2E encrypted, Amazon relays the traffic but it can’t decrypt it only the peers can.

Exactly, SAAS is much easier to analyze, that's why everyone moved to SAAS investing because it doesn't have many "flips of coin" in order to be successful.

> As far as a downturn taking down growth equity - time will tell.

As with everything. My prediction is, as the concentration around SAAS increases, more funds will be created (especially if no other instruments can produce such a high predictable growth) leading to more concentration.

If I didn't have a business to run, I would be already trying to raise fund for Series A and B to focus on non-SAAS business. You get quite heavy discount on them as there is little competition and and you again get the 1/3 business model of early stage VC, which can produce outsized returns. over just 3x.

> being hit by a bike is nothing like being hit by a car

You're completely right!

Cars are engineered to reduce the damages of a direct impact.

Bikes are not.

https://en.wikipedia.org/wiki/Pedestrian_safety_through_vehi...

Studies agree that the damages are mostly caused by speed

https://www.ncbi.nlm.nih.gov/pubmed/24435732

E-bikes can go at very high speeds (30km/h is more than enough to be deadly) and can do it effortlessly, which means the even bikers that aren't expert can go at such high speeds, increasing the risk of hurting someone else or themselves.

Add to that the fact that a car can break or avoid obstacles in a much more efficient way than a bike could ever do (think about heavy breaking with a bike at 25 km/h under heavy rain on the pavet and then think about it on a car).

I'm not a supporter of cars, I've been car free for a few years now, but I don't think bikes are less dangerous for pedestrians.

There are simply less of them around.

> The level of pain is an order of magnitude different

The maximum level of pain I suffered was because of my bad teeth

I was in a very bad car accident (a tire detached from my car while driving on the highway and I lost control), the pain was a joke compared to that.

Pain is not a strong indicator of dangerous physical damage.

For example internal bleeding is usually painless.

> A 6% interest rate on USD would be a red flag, but Dai isn't USD.

Is this written in their documentation? Cos this is where the smart money gets out. The DAI competes against the USD. So all their transactions have to be in USD. No vendor for your products is accepting these magical tokens. No one in the economy except vanishingly small fractions accept digital tokens for trade.

Also, this is how the economy functions. All they've done is create a bank and sprinkled the fairy dust of "tokens" on it so the Fed stays away.
I should add a caveat that One Medical is basically always the same price.

I've had really bad experiences with anything labeling itself an "urgent care clinic," and pricing.
The effective cost of borrowing is going to be considerably higher than 6% if a regular person is trying to pay for their living expenses with the principal of a loan denominated in cryptocurrency. Think about exchange fees, taxes for any appreciation/depreciation upon sale, the cost of tracking/filing the taxes etc.

As I said it seems like most of the DAI borrowing is being done by people taking out margin loans to speculate on crypto. Perhaps this might make sense for the limited use case of people trading cryptocurrency (which is its most popular yet pointless application), but I don't see it being useful or economically viable for general purpose loans.

EDIT: upon further thought since the loan has to be secured with crypto assets, its not comparable to a personal loan. The equivalent regular finance product would be for a portfolio line of credit. Those have much lower interest rates, fed funds + 1-3% depending on the source.
Banks don't create money, they create debt.
