Since the National Science Foundation first started collecting postgraduation data nearly 70 years ago, the number of Ph.D.s awarded in the United States has consistently risen. Last year, more than 45,000 students earned doctorates in science and engineering, about an eight-fold increase compared to 1958. But this level of production of science and engineering Ph.D. students is now in question. Facing significant cuts to federal science funding, some universities have reduced or paused their P

When I wrote about the length of file names in early Unix, I noted that inode numbers were unsigned 16-bit integers and thus you could only have at most 65,536 inodes in any given filesystem. Over on the Fediverse, JdeBP correctly noted that I had an off by one error. The original Unix directory entry format used a zero inode number to mark deleted entries, which meant that you couldn't actually use inode zero for anything (not even the root directory of the filesystem, which needed a non-zero i

Almost 20 years ago, I wrote a textbook in real analysis called “Analysis I“. It was intended to complement the many good available analysis textbooks out there by focusing more on foundational issues, such as the construction of the natural numbers, integers, rational numbers, and reals, as well as providing enough set theory and logic to allow students to develop proofs at high levels of rigor. While some proof assistants such as Coq or Agda were well established when the book was written, fo

A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented prime numbers. Similarly, a clay tablet from 1800 B.C.E. inscribed with Babylonian numbers describes a number system built on prime numbers. As the Ishango bone, the Plimpton 322 tablet and other artifacts throughout history display, prime numbers have fascinated and captivated people throughout histor

Apple is going to change how it names its next set of major operating systems, Bloomberg reports. Instead of just notching up the version number, Apple will instead mark them by year. However, the numbers will apparently align with the year after the one the update is actually released in, similar to cars. That means that the next big iOS update will be iOS 26 instead of iOS

Right-Truncatable Prime Counter This C program efficiently calculates the number of right-truncatable primes for a given number of digits. It uses a custom hash table for fast primality lookups and the primesieve library for high-performance prime generation. A right-truncatable prime is a prime number that, when its rightmost digit is successively removed, results in a sequence of primes. For example, 739 is a right-truncatable prime because: 739 is prime. Removing the rightmost '9' gives 7

A few years ago, I wrote about how 'sort -V' can sort IPv4 addresses into their natural order for you. Even back then I was smart enough to put in that 'IPv4' qualification and note that this didn't work with IPv6 addresses, and said that I didn't know of any way to handle IPv6 addresses with existing command line tools. As far as I know, that remains the case today, although you can probably build a Perl, Python, or other language program that does such sorting for you if you need to do this re
