Alternative theory: modern lifestyle with very little exercise, exposure to natural light, less face to face human contact and many addictive devices like smartphones and tv causes people to have lower neurotransmitter levels, be more depressed and looking for cheap dopamine hits which junk food provides. There is a reason people on simulants lose weight even though they have access to the same food.

If that's true it doesn't matter what's available unless you straight up introduce ban on buying excess calories. On the other hand more exercise and other lifestyle changes could help with the problem.
Finding and diagnosing bugs is annoying. Actually fixing them is super satisfying though. Same with cleaning up old crusty code, figuring out wtf it's meant to be doing is painful but turning it into clear clean well-factored efficient code is satisfying.
How Mindfulness Can Help Engineers Solve Problems
Anyone else here not even bother reading about new psychology findings? Ever since learning about the "replication crisis" and seeing how so much popular psychology has fallen victim to it (e.g. priming, ego depletion, power poses, impicit bias, stereotype threat)

I wonder if news organizations will bring in rules not to report on them until there's been a number of successful replications. They just mislead people.
I just now started reading Merritt's Adventure in Prolog (1990), and the very beginning seems somehow relevant to this thread:

"I was working for an aerospace company in the early 1970s when someone got a copy of the original Adventure game and installed it on our mainframe computer. For the next month my lunch hours, evenings and weekends, as well as normal work hours, were consumed with fighting the fierce green dragon and escaping from the twisty little passages. Finally, with a few hints about the plover's egg and dynamite, I had proudly earned all the points in the game.

My elation turned to terror as I realized it was time for my performance review. My boss was a stern man, more comfortable with machines than people. He opened up a large computer printout containing a log of hours each
programmer spent on the mainframe computer. He said he noticed that recently I had been working evenings and weekends and that he admired that type of dedication in his employees. He gave me the maximum raise and told me to keep
up the good work."
I was there for the launch of a major AWS service where they had an entire separate team working on the next iteration since well before launch (because the initial design wasn’t even intended to be sustainable). They are happy to incur technical risk (and in this case, to eat major losses in hardware costs) in order to be first to market.
That's how literally every VDOM-based framework looks, including React. Elm isn't special in this regard. It is special in many other regards, however, and I appreciate it for that. It's also interesting as one of the few languages that have parametric polymorphism but no ad-hoc polymorphism, which leads to some interesting designs. I don't like how only the BDFL is allowed to do certain things, like create new operators in external libraries, but overall, it's a very pleasant experience.
There are literally arms of the government in China that wish to silence other opinions.

If Altman feels comfortable in China it is only because he is divorced from the context there.

Amazon has an exemption policy.
Really well done and I like the brevity. Here are some ideas for revising the code:

1. There are two functions called "distance" and they're identical. Only the outermost appears to be needed.

2. As written, the game places variable and function names into the global scope. It doesn't matter for this game, but will be a problem for larger games. One idea would be to use the Immediately Invoked Function Expression (IIFE) pattern [1]. Another would be to take advantage of ES6 modules[2] (<script type="module">) to limit variable scope.

The 12-lead ECG is the standard for cardiac diagnosis in a clinic or an emergency department. This uses numerous points of contact on the skin. Each lead (whether directly measured, or virtually measured as a function of the directly measured leads) then is plotted in a standardized way. The X-axis represents time, the Y-axis represents voltage. When the voltage is toward the lead, the value is positive; it can of course be neutral, or pointed away from the lead (negative).

In contrast, when someone needs to be monitored while at home, a several-lead device is cumbersome. So, people have devised single-lead devices that can remain attached for days-to-weeks (e.g., Zio patch), or which can be activated when desired (e.g., Apple Watch, AliveCor).

A single lead ECG can be more difficult to read, in part because you simply get much less information. (Though, generally, what you're looking for [arrhythmia] is a subset of what you look for in a 12-lead ECG.)

Obviously, there are automated algorithms that attempt to read these already. However, deep learning approaches are appealing here, and at a glance this looks like it performed well and is using a reasonable set of comparisons. (Will have to read the methods section to know for sure; heading to bed so won't get a chance to look for awhile.)
Good!

They're also building a lot of homes and apartments in Silicon Valley (outside of SF). That will help ease the shortage and relax prices.
SSPL, the new license for Mongo, isn’t written to force developers already using Mongo to build apps to pay license fees. It’s designed to stop cloud companies from offering managed Mongo with closed service rigging.

I suppose Mongo could sell exceptions to cloud companies, the way other companies dual license libraries or frameworks. But even Mongo’s bread and butter paid deals aren’t primarily about alternative license rights for open code. They’re about closed add-on code and services, as you describe.

Dual licensing, on its own, is an old and plenty good model for funding development of open source code. I’ve heard wind of dual licensing deals done decades and decades ago, maybe even before GPLv2.

You’re being refuctive in your framing of his early work. At the same time as Wittgenstein was playing with words, the logical positivists were attempting to go the opposite route, and find language that both expressed meaningful things about the world and was also rigorously well formed; the meaning is a mathematical logical implication formed from empirical observations.

Naturally, they failed. Wittgenstein represents the other end of the spectrum: not only will words not save us from meaninglessness and irrationality, words can lead us straight towards them in the guise of reason.

As always, the celebrated hero is standing on giants, and they symbolize the progress rather than singlehanded executing a large leap themselves. You could apply a similar disdain to most scientists and philosophers we learn about.

I am pretty frustrated that DB services like Aurora, and now DocumentDB are still limited to last-gen instance types like r4 instead of the latest instances like r5 and t3 which have marked improvements in terms of CPU and networking performance.

I wonder if it is that they just have a so much r4 inventory left that they are forcing us to use it or if they haven't fully integrated/validated the latest instance types with their custom storage backend.

Plenty of reasonable players will touch Oracle v. Google going forward. I’m as eager to debate the opinion as other counsel. But procedural history demonstrates directly, not theoretically, that it’s effective against tech giants.

Yeah, I used to work on DynamoDB, I know it's more complicated (much more complicated than that video makes out - their code quality was atrocious, like 2000-5000 line Java classes in 3 or 4 deep inheritance hierarchies; no unit tests, only "smoke tests" that took 2 hours to run and were so prone to race conditions that common advice was to close everything else on your machine, run them, then leave them alone while you went to meetings)

There was work underway at the time I left to replace InnoDB with WiredTiger. It seemed to be very slow going, and I suspect WiredTiger being acquired by 10gen had a part in it. They also had only 1-2 engineers on the project of ripping out MySQL and replacing it, in a long-lived branch that constantly dealt with merge conflicts from more active feature development happening on mainline.

Aurora, simply by virtue of being newer and learning from DDB's mistakes (in the same way DDB learned from SimpleDB and the original Dynamo) probably has better extension points for supporting (MySQL, Postgres, Mongo) in a sane way.

Indexing into a UTF-8 string doesn't serve any reasonable consistent purpose anyway

If that's true, isn't it the job of a type system to help avoid such nonsensical operations? If "slice" only makes sense for byte arrays and ASCII strings, it could be provided on those types without being defined on UTF-8 strings.

Panics are not unsafe. Panic exists in Rust because they are safe.

That's "safe" by a very limited definition of safety. It's one step up from undefined behavior, granted, but it's not a very high standard. In practice, in most programs, you'd want to ensure that such a panic would never happen, and personally I think the language's unhelpfulness in that regard is a wart.
This is actually cool. Scala.js + scalatags has this looking like this:

```

val model = div(
button( onClick := decrement )( "-" ), // decrement is typechecked as being a function of event
div( float := float.letf )( model.toInt ) //left float is typechecked and hence the misspelling is caught at compile time so big changes can be made with confidence
)

```

It's confirmation bias. When you want something to be true because it confirms your biases, most people are not going to actively try to refute it. This is one big argument for avoiding ideological homogeneity in academia. Homogeneity reduces the quality of work since ideas that are not properly supported are less challenged than they would be in cases where ones idea goes against the biases of other researchers.

Consider the replication crisis in psychology as another embodiment of this. This was all really started when a replication study attempted to replicate a number of impactful studies from top tier psychology journals. It turns out that 64% of all studies, including 74% of social psychology studies, could not be replicated. That means if somebody actually tried to replicate any given study, they'd more likely than not find it was dodgy. But nobody did this, because there was not much motivation to do it. Refuting others' studies hurts them, likely creates enemies for you, and doesn't do all that much for your own career.

It's a messed up system that basically needs ideological heterogeneity to create that motivation needed to ensure good quality. But such heterogeneity is practically nonexistent in many soft sciences now a days, and to some degree the problem is even starting to seep into the hard sciences.

Well, the way research is usually run they look for "statistical significance" and try to have "power" of ~80% to find it.[1] The power is controlled by the sample size, which is a big determinant of how much is spent on the study so it is chosen to be the lowest acceptable value.

Anyway, my point is if there is an 80% chance of getting a result and you run two trials with those same odds, then only about 64% of the studies will replicate with the correct result (in R):

p = 0.8
res = t(replicate(1e5, sample(0:1, 2, prob = c(1 - p, p), replace = T)))

# 0 = Replicated wrong result
# 1 = Non-replicated result
# 2 = Replicated correct result
> table(rowSums(res))
0 1 2
3944 32135 63921

So, the standard practice is designed to generate a large percentage of conflicting results.

[1] 80% is the target, but is probably usually optimistic
