How much computing power would you have needed circa 2022 to compute 10^28 sums of seven integers? The sums were in the range of 1 million to 100 million so 4 bytes each would be enough. Just the storage space would be a tough problem unless you created some kind of summary table.

Was this the kind of thing you needed to rent time on a cluster for?

For students in grades 10 to 13 in UK schools who are interested in #math and #physics , there is COMPOS, essentially an online STEM club organized by the Uni of Oxford, targeted at students whose school only offers sports clubs. It is in the process of being extended to also cover #biology #chemistry and #computerScience . Registration is open until 28 September. compos.web.ox.ac.uk/

> Researchers claim to have used a #quantumComputer to factor a 2,048-bit #RSA integer.

> But the RSA number evaluated was the product of two prime factors that were too close together.

> As with a parlor magician's card deck that's been stacked for a card trick

> #Quantum #factorization is performed using sleight-of-hand numbers that have been selected to make them very easy to factorize using a #physics experiment

Hồi tưởng về thập niên 80! Cùng khám phá video "Giới thiệu lập trình trên ZX Spectrum" từ năm 1983. Một cái nhìn thú vị về những ngày đầu của lập trình và chiếc máy tính huyền thoại đã định hình nhiều thế hệ lập trình viên.

Has anyone played around with encouraging (but not requiring) students to teach one another?

One way of demonstrating mastery of the material is teaching it to others. I feel like if student A says "Student B really helped me understand the material" that increases my Bayesian posterior that student B understood the material really well (and also that student A understood it, since presumably after student B explained it, student A understood it at least better than they did before).

I wouldn't do this as the only, or even major, part of their grade, but it seems like if the grade is to reflect learning, that teaching it to others certainly reflects on their learning.

(Additional context: this is for a university-level elective technical course in Comp Sci, for 3rd and 4th-years mostly. I generally do flipped classroom and alternative grading - some combo of ungrading, mastery-based, standards-based, but I'm open to ideas. The class has about 55 students, so whatever it is can take some time but not be *too* time-intensive on me & the one TA.)
