This is a bad explanation of p values. Of the start:

> If you’re testing whether mean=0 and actually the truth is that mean=0.000000001, and if you have a large enough sample size, then YOU WILL GET A TINY P-VALUE.

Think about this for a second. Does it make sense that the results of my statistical test would change if I measured in terragrams vs. micrograms? No, it doesn't, because it's not the numerical difference between null hypothesis and sample mean, it's the difference relative to standard deviation.

If the effect size is 0.000000001 and the standard deviation is 0.0000000000000001 then this is an enormous, important effect. If the standard deviation is 0.1, then this is a really small and unimportant effect. It can still be observed correctly with a sufficient sample size though because you've stated it's a real effect to begin with.

You will absolutely not get a tiny p value just because your sample size is large. That is wrong. You will be able to detect very small effects, but if there is no difference, you are more likely to draw the correct conclusion with 1,000,000 samples than with 100 samples.

The point the author here is trying to convey but is not getting clearly, is that a large sample size can detect an effect that is practically useless and call it significant. p-values tell you if it seems probable, given your data, if there is a difference between the two datasets. They make no claims about whether the difference is material.

Example python code to do prove p values are not likelier to be smaller just due to large sample sizes, given no actual difference:

import random
from scipy.stats import ttest_ind

num_tests = 10000
res = []
for test in range(num_tests):
n = 100
a = [random.random() for _ in range(n)]
b = [random.random() for _ in range(n)]

res = res + [ttest_ind(a,b)[1] <= 0.05]

print(f"10,000 tests with n=200 {sum(res)/ num_tests}")

num_tests = 1000
res = []
for test in range(num_tests):
n = 100000
a = [random.random() for _ in range(n)]
b = [random.random() for _ in range(n)]

res = res + [ttest_ind(a,b)[1] <= 0.05]

print(f"10,000 tests with n=20,000 {sum(res)/ num_tests}")

It's really not hard to pick a natural key to use for idempotency in your persistence layer. If you don't want at least once delivery, why are you picking SQS instead of some random ephemeral queue like NATS?

I second the parent post. I've billions of messages through SQS at a previous job and I can remember having issues with SQS availability exactly once (due to a systemic failure involving DyanmoDB where cascading failures took down almost everything (and all of our integrations) that would have hosed us completely if not for our durable-queue/s3-journal[0] at the edge). SQS is simple to use, does what it says, and has very good SDK support. A++++ Would build a business on top of again!

I have a weird ancedote. I used to experience the same effect, but now that I've gotten to dangerously heavy weights (385 squats, 435 deadlift, etc...), I have stopped being able to go up in weight and sleep benefits have gone away.

I do various routines to push that number higher, but it's slow and most of the cycle I'm not at my heaviest weights.

Anyway, now I run and I get those benefits again.

Just weird how the benefits of weight lifting have slowed down with a half decade of experience..

Get Vital[0].

It has been exceptionally difficult to teach modern sound design to people without forcing them to buy expensive digital (or physical) synthesizers to learn on. Vital changed that. It democratized nearly every feature you might come across in a modern synth, and it does so better than the industry leaders (Vital kicks Massive's ass, same for Serum). If you only download one synth, make it Vital. If you're downloading two synths, you should also grab Helm[1], the creator's other freeware synthesizer.

Hobbies, travel, volunteering, education, projects, consulting - there are a lot of ways to spend your time when you don't need to worry about money for survival. Hell even if you keep working your current job, the knowledge that you don't have to and that you can walk away at any time is extremely liberating. I enjoy what I do, and I'll keep on doing it in some capacity long after I retire, but the "in some capacity" is really key.
I get that. I do think by and large, the user's agent (the browser) should be making display and format decisions based on itself, rather than the server serving different content. Though I think the exception is mobile, where we probably shouldn't serve the client endless garbage it doesn't need.

I mostly think the replacement for user agent should be a boolean of mobile or not mobile. And everything else should be dynamically handled by the client.
The downside would be that probably only a small fraction of people would read those. Which might be worth saving the annoyance of people having this reaction (and the random people convinced they are reading about anything but an art project).
Productive forests in the US are a carbon sink.

The trees grow. We cut them down. We make houses out of them, which are wrapped to prevent deterioration. The sunk carbon becomes our buildings.

Other uses of the wood are also usually carbon sinks. Paper either gets recycled (the carbon is preserved) or it gets buried in a sealed landfill where is takes decades or longer to break down.

It'd be cool to calculate how much carbon Weyerhaeuser sucks out of the atmosphere each year.
> Third, we did not have a baseline (pre-COVID-19) assessment of participants’ physical and mental health. Thus, it is impossible to distinguish the effects of COVID-19 from pre-existing conditions. The interpretation of our findings regarding depression and anxiety is further limited by the psychological burden that the pandemic may impose in general [48, 49]. While we tried to compare our results with estimates from the general population, applicable comparison data was not available. Other studies investigating longer-term sequelae after SARS-CoV-2 infection found a relevant excess risk for longer-term symptoms among infected individuals compared to SARS-CoV-2-negative control groups [9, 50].

Kind of hard to tell what this result means without a control or baseline, IMO.
> What part of their Developer Agreement where it says NOT to go running to the press, did you fail to understand?

The sentence "If you run to the press and trash us, it never helps." has been removed from the Apple developer agreement for some time.

From Macworld:

> It’s good that they removed that because it often seems like the only thing that helps.

https://www.macworld.com/article/234332/hey-there-apple-s-pu...

The suggestion to avoid the press is terrible advice. Apple has much more leverage in its relationship with any single developer, and bad publicity is in many cases the most effective way to reduce this disparity.
Has anyone else found that battery packs with wireless charging kinda suck?

I lost my non-wireless one so just bought a new 10,000 Anker one with wireless charging.

Is this just the inefficiency of wireless or am I doing something wrong?

>"Why cant we just plant more trees?"

We can, and we certainly should, but that does not solve the problem because those trees will eventually die and that carbon will cycle back through the biosphere. Mankind extracted a ton of carbon from the ground, where it was locked away, and we put it back into the air. People are trying to find ways of putting all that extra carbon back somewhere where it won't affect the cycles in nature. Trees just temporarily lock up carbon.

I look at the Marvel movies and TV shows and think about a Westerns in the 50's. They were hugely popular, there were a ton of them and some actually were quite good. in the fifties the three networks produced 90 different Western series. But now theres not a single one, and you could count the number of of Hollywood westerns on one hand, and people wonder about the awful taste which must have supported this environment.
Also, there's the case of ISP's just dropping idle TCP connections. It can also take a while to determine that a TCP connection is broken.
Thank you for providing numbers.
We can, how many have you planted?

The problem is the space issue and that it takes a decade or two for there to be meaningful carbon uptake.

Most land is private so you can't go around planting willy nilly. What's worse is that you are technically not allowed to plant on most public land either, although for small amounts of native species, you can sneak by.

> I think it's a bit unfair that the ones that are cautious towards the vaccines are default labeled as "news" from Facebook conspiracy groups.

You seem to have missed the part where they made specific claims about dangerous side effects or major adverse events, but when pushed for sources or evidence, demurred.

It's clear they formed an opinion based on very bad information. Where did that information come from? I think the answer is obvious.

As for the rest, honestly, you have three pieces of anecdata, none of which align with any other reported adverse events from the vaccines. I'd be a little surprised if the doctors did explore that theory before ruling out more traditional avenues of investigation first.

I am in the same boat. I am 6 months into FIRE, and the list of things to do is growing, not shrinking.

However, I would say that some things on the list turn out to be false. That is, I like the idea of doing them, but not enough to actually do it. So do account for some of your post FIRE ideas turning out to be just daydreams you aren't actually committed to.

I'd think in terms of how much it costs to hire these people and what Fidelity's profit-per-employee rate is, as that should in theory give an idea of a lower bound for how much they expect to earn from crypto.

Yeah I was scratching my head reading this article; they're bending so far backwards to avoid the obvious solution that I thought they were gearing up to pitch some competing tech.

> If the sender's queue starts to experience back-pressure, webhook events will be delayed, and it may be very difficult for you to know that this slippage is occurring

I've never before seen anyone try to argue that properly dealing with backpressure is a bad thing. The author's proposed model makes this situation even worse. With kafka, consumers can continue processing the event stream and you can continue to serve reads from your primary datastore. With the author's model the event stream lives in your primary datastore, so if that starts to lock up the blast radius is much larger.
Yeah with oil reserves we know of today, most estimates put it around 50 years before we run out of it (that's with the current consumption, it doesn't take into account a completely possible increase in consumption).

That doesn't mean that a) we should extract all of it, and b) we won't find more of it.
I think you're anchoring to the idea that Apple produces Veblen goods, and trying to work backwards from there.

The more straightforward explanation is that Apple just wants to make it easy to buy on credit.

I disagree that Apple products are Veblen goods in the same way that, say, Prada products are.

It's not poor design because it wasn't really designed in the first place...because it didn't really need to be designed.

There is a standard and it's minimal:

- config files are text files
- # indicates a comment

Why standardize further when the types of programs that require config files run an extremely wide gamut? Types of programs can be as diverse as web servers, graphic editors, kernel modules, networking programs, etc. Each are vastly different. I don't need to wait for, worry about, or try to install an updated registry processor that knows about new object types. Better to build it into the program or rely on a library. Why change the entire system of configuration storage just for one new type of program?

And text files are awesome for another reason: With the ability to comment config files you can understand any format - as well as include notes and conveniently have documentation where you need it.

Also: You can't use git or other versioning to backup your registry keys and rollback to previous versions.

Trees in forests are self-replicating. When one dies another grows in its place.

sure there are some people that get meaning from work, and who would have trouble finding meaning outside of work. But I can't agree that 'working for the man' and doing whatever you can do to get by is the best recipe for finding the most meaningful work for most people.

In some cases "working for the man" isn't bad and it does give people purpose, but in (imo)the majority of cases, it is bad because it prevents you from using your time to do something you actually find meaningful.

I think the few people who are able to find meaning in their jobs are either extremely lucky to have found what they want to do, had the opportunity to pursue it and succeed, and make a decent enough living doing it without the money aspect killing their joy - or they're the type of people who have just 'over-assimilated' to modern life and found a way to extract meaning from their work, but these people would probably be able to find at least as much meaning and happiness in something else if they grew up in a world where working wasn't expected to be almost your entire life.

monadic IO is basically a type of effect system.

the big issue is that you have to do a LOT of complex shuffling of types and values in order to deal with effects.

You can actually avoid a ton of this by thinking about purity in a less expression-level way, like how Koka does it. And, I think I'd probably try implementikng something like it (or eff) in my language.

> No one can deny that it would be very hard, almost impossible at this stage to admit the existence of a problem should one be identified.

On the contrary, publications would salivate at the prospect of dropping a bombshell like this. People love reading and watching salacious, outrageous coverups and how they unravel.

You would need a multi-national conspiracy with various state and private actors coordinating and suppressing information about negative effects of the vaccine for it to be at a scale "equally dangerous" to the extent of the deaths and injuries caused by actual infection.

And it's not like we have no data about negative side effects. We have data on side effects: getting them is literally a handful in a million chance and they're manageable when they occur[1].

To be extremely fair to hn: almost all such studies about human behavior, especially those relying on polling, are garbage.

Often, the statistical methods are inappropriate at best, or downright deceiving at worst; there is nominal, if any, understanding about what "controlling for a variable" means, among many other such things. Not to mention that often the methods themselves are highly questionable in their reproducibility, statistics aside.

(Another classic is to point out flaws in generalizations for mice studies and such, but that is, imo, independent of the study's methods. It's a fair critique, but I don't think it's what you're interested in measuring w.r.t. "bad" studies.)

Hey man, similar thing here. Every six months or so, almost to the day, I've got a spell for about 7-10 days where I have an immense fatigue, like sleeping 12-15 hours at a stretch, and a brain fog that makes it impossible to concentrate on anything. Then it all lifts, and I go back to my usual 7 hours a night, thinking all day and night. This all started for me in February of 2020, too, just before the lockdowns; I didn't get a positive test at the time because my live-in partner did receive one -- the testing clinic said with the positive exposure to just stay home and go to the hospital if I can't breathe -- since then we've both had the same symptoms at roughly the same occurrence.

It sucks.

Six months after the end of a mild case: occassional heart arrhythmias, but getting less frequent. I got medication (Concor) to control them.

Muscle twitching, also getting less frequent, but increasing after exercise or caffeine. Incidentally, the cardiologist who takes care about my arrhythmias has after-Covid muscle twitching too and a few days ago told me that another of his patients, fresh after Covid, has them as well.

So there seem to be lingering issues. Hopefully not of the fatal or life-shortening kind, but this cannot really be ruled out.

BTW My Covid was really fairly mild, only about 30 hours of fever and sweating plus a few days of blocked nose. No pneumonia or even much cough at all.
