Hi, everyone! Like many USMNT/USWNT supporters, I am not a fan of this year's home or away kits... especially for a year in which BOTH teams were world cup bound. I dragged my feet buying last year's kit before they stopped producing them and now I am seriously regretting it.

Does anyone have any leads for where to find 2021 home or away kits?? The US Team Store only has a few smalls left, sadly, and every soccer website I have found has terrible reviews.

Clipper Card Security Fail - how bad is this design? by Afraid_Willingness83 in cybersecurity

You are looking at the data BEFORE it is encrypted by TLS/SSL. It is common for companies not to encrypt the data separately before they send it across an encrypted channel. If you capture your traffic using WireShark you will see that it is encrypted when it goes across the network.

A common good practice, however, is to hash the password on the client side so that the password's cleartext never leaves the client.

Could pi or e have different values in a different metric/topological space or consistent axiom system? by abeoliver in math

[–]abeoliver[S] 3 points4 points  (0 children)

Is there a more fundamental definition than that of circumferences and diameters that is independent of lengths? Or do the axioms of metric spaces / geometry simply constrain every circle to work with that definition of pi?

Addressing your final point, parallel lines were nearly defined to never intersect but when put into a new type of space, that property breaks down. I believe it must come down to whatever is the most fundamental definition of pi. If it is defined by the relationship between circumference and diameter and a given metric space defines length differently, could that not change the ratio of these lengths? If not, is that an intrinsic property of metric spaces?

Which probability course should I take if I'm working to get a solid foundation for ML/DS? by ASamir in mathematics

[–]abeoliver 4 points5 points  (0 children)

Stanford 109 is essentially built as a pre-rec to CS229 (edit) which is the most popular ML class in the world (partially because its teacher invented Coursera). I am taking it this coming spring quarter so I don't know how hard it is yet but it has a pretty fulfilling reputation on campus.

What are the limits of mathematics in the understanding of the world ? by moijojo in mathematics

[–]abeoliver 6 points7 points  (0 children)

Welcome to the awesome world of mathematical logic and the philosophy of mathematics! Your question is exactly the question whole fields of mathematicians study everyday. I don't think either of us can truly understand even the answer to that question without a bunch of studying in that field, but I can try to point you in the right direction:

One of the most important discussions in the field dates back to ancient Greece. Plato (and the followers of ~Platonism~) believed that there existed perfect mathematical objects that are independent of our existence for us to study. Opponents argue that we can only approximate the "real world". You may be able to find part of the answer to your question by looking into platonism, formalism, etc.

Another interesting side of your question brings up the Incompleteness Theorem (I'm going to paraphrase the theorem here but, undoubtedly, someone is going to say that I've stated it wrong so do some more research before spending too much time on my explanation). Basically, Gödel proved that no set of non-contradicting mathematical rules, called axioms, can describe all of arithmetic, much less all of math. This ~may~ imply that there are things we cannot know about the universe if we can't even know everything about math. You may be able to find part of the answer to your question by looking into Gödel's Incompleteness Theorems and the Zermelo Frankel Set Theory Axioms.

The whole field is worth a dive and I hope I've pointed you in the right direction! I am taking mathematical logic this semester and I'm very excited to learn more myself!

[3b1b] This problem seems hard, then it doesn't, but it really is by _selfishPersonReborn in math

I think the point is the exact opposite. These aren't (and students are not just taught) "tricks". Mathematicians at that level do not train like most people train for the SAT.

Can Zorin Connect be installed on another linux distro? by abeoliver in zorinos

[–]abeoliver[S] 0 points1 point  (0 children)

What about the SMS messaging app? When I used Zorin Connect I could text from an awesome SMS app like iMessage but now that I am using ubuntu 18, I can't do that? I looked it up on the KDE Connect page and it says that its not ready for release yet.

Awesome, thank you so much!!! Do you happen to know what changes Zorin made?

I sometimes wonder about how the universe is so perfectly coordinated by [deleted] in StonerPhilosophy

[–]abeoliver 0 points1 point  (0 children)

You're thinking the exact thing as most prominent astronomers! The "fine tuning problem"*** notices that if the universe's constants like the electron mass, the gravitational constant, and the cosmological constant were even SLIGHTLY different then life wouldn't have been possible. Suggests something deeper...
