I love that this article includes a test program at the bottom to allow you to verify its claims.

This is a very old answer about the M1, but yes what you’re saying is possible: https://stackoverflow.com/a/67590869/230778

While you can cause the compiler to run longer to squeeze the binary size down, the compiler has a baseline number of compiler passes that it runs over the IR of the program being compiled. These compiler passes generally take time proport

Just a small piece of feedback, it looks like there's a small typo on the last paragraph of the page: > Interviews can be scheduled (and rescheduled) interviews around the clock, 7 days a week. I believe the second `interviews` shou

Other posters have pointed out that this is incorrect, but I wanted to give a bit of intuition as to how signals can be received when they are below the noise floor. First, as a definition, below the noise floor means that the power of my s

I ran into an issue like this in my first ever job! I accidentally filled up a cluster with junk files and the sysadmin started sending me emails saying I needed to fix it ASAP but rm wouldn’t work. He taught me that file truncation usually

Yes, that’s what it means for me. I’ve never heard someone use the word arbitrary to mean anything other than “a random choice”, or even “a poorly thought-out choice”. My professors in grad school explicitly discouraged use of that word any

I really like the integration of lower-level memory control in a superset of Python. Trying to maintain compatibility with such a large and varied ecosystem is a daunting task, and has the opportunity to be very valuable for many people wh

It is a little disappointing that they're setting the bar against vanilla Python in their comparisons. While I'm sure they have put massive engineering effort into their ML compiler, the demos they showed of matmul are not that i

Small correction; it’s DisplayLink, not DisplayPort. You have to use DisplayLink because they do some part in software as a part of their driver (which you must download and install) whereas the native Apple stuff has some internal hardware

We actually use this in our CI system to limit write access outside of the build environment’s build folder. You can see some Julia code that generates the sandbox config rules here: https://github.com/JuliaCI/sandboxed

This linear scaling per-core doesn't match my experience with using the AMX co-processor. In my experience, on the M1 and the M1 Pro, there are a limited number of AMX co-processors that is independent of the number of cores within th

My guess is that it’s due to git looking at its own base name to figure out which command it’s supposed to run as, kind of like busybox does.

To add to Keno's sibling comment, Julia, as a JIT compiler, essentially creates large chunks of standalone, "static" code, and runs those as much as it can, breaking out into the "dynamic" runtime when it has reache

In the Julia world, we make redistributable binaries for all sorts of things; you can find lots of packages here [0], and for LLVM in particular (which Julia uses to do its codegen) you can find _just_ libLLVM.so (plus a few supporting file

Imagine instead of getting a grid of pixels once every 30th of a second, you instead get one pixel’s value, alone with its location, along with the time stamp at which the pixel’s change was noticed. Event cameras can have very fine time st

Note that the restriction on external monitors can be worked around by using a DisplayLink compatible dongle/dock, since it uses a custom driver (I assume it does something in software that would otherwise be limited in hardware). I us

In case there's anyone out there with an M1 MBP that desperately wants multiple monitors, if you use a DisplayLink compatible external dock, something about the alternate driver that such a dock uses allows for multiple monitors. I pe

We call these "system images" and you can generate them with PackageCompiler [0]. Unfortunately, it's still a little cumbersome to create them, but this is something that we're improving from release to release. One po

Yeah, we've managed to get Julia itself running pretty well on the M1, there are still a few outstanding issues such as backtraces not being as high-quality as on other platforms. You can see the overall tracking issue [0] for a more

They are talking about total operations, but since big O notation ignores constant factors, and they explicitly ignore the addition steps (because for large n multiplication dominates) it is, in effect, only looking at the multiplications.

You pay a price for the super-small frame sizes; much worse compression ratios. Frame sizes smaller than 10ms disable the LPC and hybrid coding modes, which are quite advantageous. [0] In my experiments with transmitting realtime audio sig

Julia's SIMD programming model is still very much a work in progress; I think we have a way to go in providing the kind of flexibility and control that languages such as ISPC, Halide, TVM, etc... provide. That being said, packages such
