How can I check if my phone is emitting these packets?


Install NoRoot Firewall as HenryBemis mentioned, it's on the Play store. The app tells you what IP addresses apps are trying to communicate with in a fairly neat and simple way.

I've just installed it on my 6.1 Plus. Nothing sus yet but it's only been 5 minutes.


I did install it too on my 6.1 and found the System app trying to connect to several cloudfront IPs, cant find any kind of extra info, did you find the same?


How did you get the music industry companies to agree for you to directly upload files to them?


The interview mentions parked domains as the major lead generator... are those domain names owned by park.io or by its clients?


Mostly clients


What is the generalised rule/case where small sample sizes are sufficient?


If the difference between samples is VERY large, you don't need a very large sample size.

In other words, we're trying to find the chance that the result we got was due to chance. Let's say you have numbers like these:

A: 11, 11, 12, 12, 13, 13, 13, 13, 13, 13, 14, 15 B: 90, 92, 93, 94, 94, 95, 95, 96, 97, 99, 99, 101, 101

What is the chance that those two samples come from the same distribution?

On the other hand, if A averaged something like 12.5 and B averaged something like 12.4 it would require a huge sample size to prove that those two samples come from two different distributions.


That sounds intuitively reasonable. Is there a cononical reference argument that you're aware of?


I'm really talking about https://en.wikipedia.org/wiki/P-value

Most people just look at the number of subjects in a study, but not the p-values


Thanks.

Depends on what effect size or power you are looking for and/or other factors like variance in the data (standard deviation), etc. There are some different ways to calculate sample sizes here: https://en.wikipedia.org/wiki/Sample_size_determination

or google: sample size calculator


Went through the effort to find the video, you are a very good presenter! did it come naturally or did you work on it? if so how?


I'm a little ashamed to say it came naturally (I feel like that's a cop-out answer but I don't have a better one).


Can someone please explain what would be the reasons for Atlassian to IPO? Is it to return money to investors? fund new things (such as?)?

How does BuiltWith decides which sites to crawl? assuming it is too complex to crawl everything.

And how is the data/queries being sold without compromising it...


I believe that they started via user submission of URLs to crawl. I used to submit tons of sites that I was curious about and eventually got their Chrome browser extension so I could find out the tech behind a site by clicking that little button.

Not sure if this is how they scaled out to the volume of sites they now cover.


"when you don’t create things, you become defined by your tastes rather than ability. your tastes only narrow & exclude people. so create."


Looks like a very good resource, however which prior knowledge does one need to have to understand this book?

e.g., do I need to know bayes' rule? bayesian inference? etc.
