I'm curious as to whether the techniques used here are safe against Spectre-like attacks. There appears to be a heavy reliance on indirect branching. The slides here are dated just before Spectre was published, so it would not have bee

wxHexEditor has a similar look and feel to WinHex, and similarly supports editing of extremely large files or raw devices. It's nowhere near as featureful but still very useful, and doesn't have the proprietary license. https:&#x

I would say work on a project that you want for yourself, regardless of whether or not if there is a market for it. If you're already in a well-paying job, money should not be the cause of your concerns. Work on something out of princi

The problem might not be your script, but that the system is stateful. Users can access and mutate the /usr directory, and some software will do this outside of the system's built-in package manager. You can also compile and link

I believe this is meant to be used in combination with a low-bits pointer tagging scheme. One of the low-bits tags represents a float value, and you insert this tag into the NaN-space of a IEEE-754 single-precision float in the full lower 3

I was commenting mostly in jest anyway. The purpose of the standard is to give a numeric code which is language agnostic, for internationalization of forms and software. Adding other genders isn't really applicable, since there's

An issue with many languages is the presence of mutually dependant parts of code, because how do you generate a content-hash for something whose constituent part's content-hashes depend on it? Merkle trees can be generalized to DAGs, b

There's a report video button on top of the video for these. Far too many incorrect videos ruins the game a bit: You're on a streak and no video means you can lose 3 lives. I've reported about 50 videos so far.

You probably don't want all the platform-specific stuff in a capability based language, because the filesystems in mainstream OSs are not capability based, and you can't sugar-coat a non-capability system with capabilities. The ca

Other reason to move them outside of the function: you might want to prepare them in memory in a way that could speed up the comparison further, which would only need to be done once, not each time the function is called. For example, using

`dynamic_cast` does a dynamic type cast (a downcast). It does what it says on the tin. It's purpose is to cast a value whose precise type may not be known until runtime.

Yes, downcasting performs dynamic type checking. There are no two ways about it. C++ correctly calls this `dynamic_cast`. The only way to completely avoid dynamic type checking in such object hierarchies is to forbid downcast completely, as

The set of RISC-V processors is going to be far more diverse than you are expecting. There's already dozens of open cores, both 32-bit and 64-bit, with varying support of standard extensions. Assume RVG64GBCV, do we skip P, T, Q? What

There's far more than 2. Even just taking RV32I, you have M, A, F, D standard extensions which are all optional. A CPU could include any combination of these, so you have 3! possible instruction sets off the start line. But let's

Practical use is double-precision floating-point constants, preprocessor generated bit-flags, high-bits pointer tagging in dynamic languages, etc. Having to read them from memory or expend multiple cycles to materialize them into a register
