If Time Can Pass, Time Can Pass at Different Rates

Rethinking First-Time Pass Rates as an Academic Quality Metric.

Can string kernels pass the test of time in Native Language Identification?

We describe a machine learning approach for the 2017 shared task on Native Language Identification (NLI). The proposed approach combines several kernels using multiple kernel learning. While most of our kernels are based on character p-grams (also known as n-grams) extracted from essays or speech transcripts, we also use a kernel based on i-vectors, a low-dimensional representation of audio rec...

Why Does Time Seem to Pass

According to the B-theory, the passage of time is an illusion. Although times are objectively ordered, with every time earlier or later than every other, no time is objectively past, present or future. The A-theory, by contrast, says that time passes. Here I shall use the term ‘A-theory’ to include any ‘dynamic’ view of time; the term thus encompasses presentism, growing block theories and shri...

Why Crack When You Can Pass the Hash?

A weakness exists in the design of Windows unsalted password hashing mechanism. The static nature of this password hash provides the means for someone to masquerade as another user if the victim's hash can be obtained. While the concept of passing a Windows password hash has been around for some time, the release of publicly available tools has taken the first major step towards harnessing the ...

How Many Random Points Can a Regular Curve Pass Through?

Suppose n points are scattered uniformly at random in the unit square [0, 1]. Question: How many of these points can possibly lie on some curves of length λ? Answer, proved here: OP (λ · √ n). We consider a general class of such questions; in each case, we are given a class Γ of curves in the square, and we ask: in a cloud of n uniform random points, how many can lie on some curve γ ∈ Γ? Classe...
