Even Terry Tao struggled at times: "When I was a graduate student in Princeton, Tom Wolff came and gave a course on recent progress on the restriction and Kakeya conjectures, starting from the breakthrough work of Jean…
There is a joke saying "a mathematician says X, writes Y on the board and means Z". The really amusing(?) thing is that other mathematicians still (sort of) perfectly understands Z. Once you have enough experience you…

There is a cute argument (I think it is due to Erdos) that, asymptotically, 0% of the integers in [0,n^2] appears in the "n by n multiplication table": By Erdos-Kac, almost all integers of size about n^2 have about…
I had the same impulse (or at least copy.fail inducing many to upgrade at the same time.) However, it might be a "pro-Iran hacktivist group" according to https://www.theregister.com/2026/05/01/canonical_confirms_ub...…
Convolution alone does not smooth. Eg consider a random variable supported on the pts 0 and 1 (delta masses at 2 pts.) No matter how many convolutions you do, you still have support on integers - not smooth at all. You…
Read it as a young teenager, can recommend.
This has been discussed on HN some times before. User xornot looked at the zfs source code and debunked "faulty ram corrupts more and more on scrub", for more details see https://news.ycombinator.com/item?id=14207520
I don't think this is entirely due to Wozniak. Early "home" computer systems were based on connecting cards to a bus (eg the S-100 bus), eg. with one card supporting the CPU, another RAM, a third for disk drive, video…
Fun historical fact: knot theory got a big boost when lord Kelvin (yeah, that one) proposed understanding atoms by thinking of them as "knotted vortices in the ether".
If you have a child who likes math I highly recommend "Really Big Numbers" by Richard Schwarz. Tons of nice illustrations on how to "take bigger and bigger steps". "Infinity is farther away than you thought."
I recently got into making some sort of budget hifi setup, and found audiosciencereview.com quite helpful - a good amount of reviewed gadgets with focus on measurements. Ended up with kali lp-6v2 speakers and a SMSL…
I have used merlin for quite a while, mostly happy (except for some security holes...) However, once asus drops support for older devices (e.g. rt-ac68u and rt-ac86u), merlin might also drop it. For now rt-ac68u is…
Based on reddit [1] and other some other recommendations I got an asus ax4200 and put openwrt on it. I'm fairly happy, but some people have run into connection dropping (possibly due to ISP power saving resulting in…
PS: if you're interested in multiplying "ludicrously large numbers", Harvey and van der Hoeven had a nice breakthrough and got multiplication down to "FFT speed" (n*log(n)), see…
There is a nice picture of the "best" for different ranges of sizes of numbers to be multiplied at http://gmplib.org/devel/log.i7.1024.png More context and explanation can be found at: http://gmplib.org/devel/ BTW, I…
Check out "Diamond Age" by Neal Stephenson.
It's very inefficient, both on terms of runtime and in terms wasted entropy.

There is an extremely nice "Digital show and tell" video by Monty at https://xiph.org/video/vid2.shtml (part 1 at https://xiph.org/video/vid1.shtml is also very well worth watching.)
I lived in the states for a while and missed Bregott. "Land o Lakes butter with canola oil" is a pretty good substitute.
According to https://www.servethehome.com/hpe-proliant-microserver-gen10-... the 10+ seems to run freenas fine.
