Do you find that all of your financial institutions offer reliable OFX/CSV feeds? I'm asking because I've generally come to the conclusion that PDF is the only universal data format that every institution will offer.

> Importers have been great. What importers do you mean? Are these importers you've written yourself, or existing importers you were able to reuse? What format are these importers pulling from (PDF statements, CSV, OFX, etc)?

> surely neither version guarantees that the generated code is branchless, it's all still up to the compiler. That is true, and the article mentions that GCC did not want to generate branchless code in this case, and thus performed

Yes, I agree that higher-resolution data is not readily available. LLVM MCA has a timeline view that attempts to visualize the overlapping execution of instructions ( https://llvm.org/docs/CommandGuide/llvm-mca.htm

by haberman 5y ago
The visualization tools presented look really nice, but they seem to present program execution as sequential and linear, which is a model that seems like it will really break down at these time scales (10s of cycles). Modern processors will

If the modeling is this good and this accurate, it would be helpful if consensus predictions were published in a prominent outlet that is easy for the public to consume and compare against empirical data as it comes in. I think this is par

"Read" here is shorthand for "call a const method". You can write const methods that are not safe to call concurrently: for example, they could use "mutable" or "const cast" to perform mutation, or t

I agree that the writes are synchronized with the reads in my example. But the reads are totally unsynchronized with respect to other reads, in every sense. That is what thread-compatibility guarantees you: concurrent reads without synchr

> reads are always unsafe when there is a possibility of writes. That is correct for any reads that could race against a write. Writes must be synchronized with all other operations. But reads may proceed in parallel with other reads wi

My gut is that computing key (given reliable pitch data) is a lot easier than computing polyphonic pitch data (given audio). For relatively "conventional" music, there are very strong signals of key like beginning and ending chord

The point of the exercise is to show that the C++ idiom doesn't make sense in Rust. It's certainly not trying to imply that Rust is being unreasonable for rejecting a direct port of a C++ idiom. I do think the ambiguity mentioned

Yes that is a good point. I will see if I can fit this into the article without introducing too much digression.

Which documentation do you mean? The Abseil docs I linked to ( https://abseil.io/blog/20180531-regular-types#data-races-and... ) are talking about thead-safety of types, not functions.

Not exactly. I was just trying to show the most direct port possible of the C++. In C++, Increment() is a non-const method, so in Rust I made increment(&mut self). The point is to show that thread-safe types are expressed differently
