Not just pointers, it also has info such as alignment. (Shameless plug) I wrote a relevant article recently: https://ashdnazg.github.io/articles/26/Downcasting-Arcs-in-R...

Maybe Optane was just a few years too early. There's finally a demand for a middle ground between RAM and SSD.

I worked on a transpiler from Nand2tetris assembly to WebAssembly, and had some really annoying memory corruption bug that I just couldn't solve. That is, until I checked the program I used for testing (which I didn't write), and

Kind of depends on the definition of no one. If the company puts an artificial proof of work demanding a rack of the latest data center GPUs, that should be illegal. If the binary has the same hardware requirements that the company used whe

The key is communication. If the company says the binary has a certain min. requirement, then the vast majority of people will accept that. Of course there'll be idiots, but I doubt you'll see a stronger backlash than to a company

The real question is how many other things it's missing. Reading the process in TFA, it's very much dependent on the comprehensiveness of the testing framework. And apparently, the tests never built a lobby in the bottom left corn

I'm back to searching for numbers that are palindromes both in decimal and in binary. [0] I had an insight the other day, that as I fix the n least (and most, it's a palindrome!) significant decimal digits, I also fix the remainde

I did some manual golfing with nand2tetris assembly and developed similar hacks to the max() implementation, where one appropriates an arbitrary, conveniently placed, memory address. After reading the article, though, I feel like I definit

I can also thoroughly recommend https://store.steampowered.com/app/684270/Silicon_Zeroes/ which uses smart design to remove having to deal with binary in the circuit design. This reduces complexity by a surpr

No idea if it's not already optimised, but x2 could also be x*x and not just abs_x * abs_x, shifting the dependencies earlier.

In academia, seeing your research being published by someone else sucks, but the consolation prize is that you know you had the right instincts choosing what to research.

My wife did one of the years in Matlab. Some of the problems translate very nicely into vectors and matrices.

The bare basics are working with a hex editor and understanding data types - ints, floats, null-terminated strings, length-prefixed strings etc. I'd recommend taking a well documented binary file format (Doom WAD file?), go over the do

First of all, really cool initiative! It's interesting that a bunch of the funded products have been funded by a single person. Do you know if it's the producers themselves? Worried rich people?

O(n^2) isn't required. One could do an in-place merge-sort, which is also always worst case, but with O(n*log(n)). I suspect everyone turns to Bubblesort since the inputs are small enough that it doesn't matter (evident by the fac

You could copy the instruction to a 16 byte sized buffer and hash the one/two int64s. Looking at the code sample in the article, there wasn't a single instruction longer than 5 characters, and I suspect that in general instruction

Yes, and I would even go as far as saying that even being functional isn't required. Trying to make something cool and failing counts as "hacker spirit". It all boils down to getting your hands dirty, instead of passively con
