Love the concept, well done.

I was slightly annoyed at the dog puzzle, while i tried to rotate the boxes which contained just grass and a lot of bokeh. I guess picking the right pictures is really important.


No nerdle fans here?

Kind of a fan - but for some reason the UI is really bad for me in Firefox. You cannot type `/` or `Enter` - you have to use the mouse for those. And it kept saying things did not compute, even though it was a valid equation.


From their play store description:

"Best of all: No upsells, no in-app purchases, and free for life. Website owners pay us to make your Internet faster so you don’t have to."

That sounds totally against net neutrality to me. Unless website owners are not getting preferential speed up.


The description does not mean website owners are paying so that users of this app can get a faster connection to them. It just means website owners pay Cloudflare already, Cloudflare’s business model is selling services to website owners, and so this dinky app for consumers has no need to make money and therefore is free.


Wellll.... paying Cf customers will get lower latency service using this, just as Cloudfront gives better service to AWS users.

That’s part of why this app is in CF’s interests.


This app only redirects DNS, it does not tunnel any other networking. The DNS speedup someone will get by using this app applies to all domains, not just those of websites that pay for Cloudflare.


Second that.

I was stumped multiple times trying to find this app under apps starting with letter "H" on my phone. Moved it to home screen now, but the name can definitely be improved.


Atleast fix the spelling: Rewiews -> Reviews



I think it's mostly because mathematics is taught as is with little or no attention to practical applications of the theory. For instance, till date, I could not see how eigen values/vectors are useful.


One nice application is that the eigenvectors of a stochastic matrix correspond to stationary states of the Markov chain. That leads naturally to a conversation about PageRank, which is super useful because it made billions of dollars for some people. Then you could talk about the use of eigenvectors for principal component analysis in data science, which is making a lot of money for other people right now. If these examples are not useful, then I don't know what is.


Thanks, the application to PageRank looks interesting. I shall resurrect my knowledge on eigenvectors and eigenvalues and make some sense out of it.


Interesting. Eigenvalues and eigenvectors are one of the most fundamental applications of linear algebra. In physics, quantum mechanics is a giant eigenvalue-eigenvector problem.

One application I really like is in machine learning: the eigenface algorithm.


That might all be the case. I would simply like a thoughtful introduction to the topic about where this abstraction comes from. What is the idea behind it and what was the motivation for its invention?

After I understand the plain English concept, then give me the math notation and proof and applications.

The way it works today is often to simply leave out the first part and I believe this is why many people find it hard to develop intuition and a real understanding of the concept.

For man it's just there, you memorize it, you apply it, you take the result and simply have faith that it is what you need because some book/ prof said to solve problem X use eigenvalues.


The simple idea is that while linear maps(matrices) are generally a combination of rotations, scaling and other stuff in higher dimensions, sometimes they will act on a vector simply by scaling it.

Since scaling is a really easy operation to understand, the space generated by these vectors will be really easy to understand. Note that different vectors can be scaled by different amounts.

Now it often turns out that the space generated like this is actually the whole of the space under consideration and this really simplifies the linear map we started with. Hope that helps.


I wrote something similar sometime back: https://github.com/ashisha/x-cut-copy-paste

But the ability to list the files being copied is brilliant indeed.


But that defeats the Conginitive Dissonance side of the things. If the offer is available daily (or even weekly), then the employee can just quit the very day (or next week) he feels crappy about his job.

Right, or did I miss something?


How is it a problem that people who have such a tenuous attachment to their work that they'd quit next week for a bit of cash as soon as they're feeling down do so?

Seems like a great outcome for both the employee and the employer.


for me its jeff.morse@d214.org


Yup, same for me here. WTH is going on??
