The difference is that software compilation is a fairly local optimization process - allowing you to change/inline one bit of generated code without significantly affecting the per…

I'm not sure whether their fees are really that low. For transfers between your own accounts, for anything over very small amounts, I found that their 0.35% variable fee is pretty …

Your gain in delta (due to the stock moving) will be offset by your loss in vega (due to the volatility coming off after the impending crash). Option fair value is a function of bo…

It does load it - mmap doesn't copy the file content into a buffer, it merely allows you to operate on a file as if it were in memory. Memory reads correspond to file read operatio…

That'd be special relativity for you - nothing ever exceeds the speed of light, hence a corrective factor needs to be applied. https://en.wikipedia.org/wiki/Special_relativity

If you would write a basic scheduler, at some point you'd have to await the userspace code but you wouldn't have any way to force it to stop running. If the userspace code would en…

As described in the blog post, the rust compiler generates a state machine for every async function and generates the appropriate poll methods for the state transition. This is fun…

Intel tried that with Itanium. It didn't go well.

The issue was that there wasn't a cheap riscv board that supported the privileged section of the ISA (so you can run an OS on it). This, being a microcontroller, doesn't either.

Not Google being good - Irish law has been changed such that it's no longer permitted. "The legislation passed in Ireland in 2015 ends the use of the tax scheme for new tax plans. …

Unfortunately true exponential growth of a physical system cannot exist - it'll always be some sort of logistic model that looks exponential near x=0.

How would electromagnetism work in a world without a cross product?

One example is if suddenly you would require to inherit from the same object multiple times. Example - if you have a "team" object, you might at first inherit it from a list/set (a…

The most certainty you are going to get is by taking an open source processor core, and run it on an FPGA with an open toolchain. You won't be able to check the actual FPGA chip, t…

I doubt those are more complex to parse than C++, as C++ parsing is undecidable. http://blog.reverberate.org/2013/08/parsing-c-is-literally-u...

Though it might finally do away with the ever-persisting Windows error messages about "this file is already open" followed by a search through all of the processes that might have …

Yes, but you can't install a LIDAR over a software update. They've been promising full self-driving mode and getting closer by updating the software - the owners that already have …

I've attempted to run it (not with this latest release yet though) and it appeared as if calling a numpy function essentially disabled the JIT for that function, which was not acce…

Some NICs are able to dump data directly into the (L3) cache (DDIO on Intel), so either the L3 will have to be encrypted or the IOMMU needs to contain the crypto functionality.

The RAM does not know anything about locking, it's the cache coherence protocol. The CPU will request a cache line in exclusive state, it does the operation on the memory and ensur…

Unlikely any time soon - most HFTs will have massive, battle-tested C++ code bases already. The data ownership model in HFT is usually very clear - receive packet, pass through som…
