Can Wachy be used to trace kernel code as well? And would you need to do anything specific to get that to work? (How would Wachy find the kernel sources?) I was thinking this would be pretty cool to use for debugging device drivers on embed

Since you seem to know, what company would one go to for fabricating a 500nm chip these days at that price?

Does the PhantomData type in Rust do what you want? Or are you talking about something slightly different? https://doc.rust-lang.org/nomicon/phantom-data.html https://doc.rust-lang.org/std/marker&#

AMD’s primary advertised improvement here is the use of a TAGE predictor, although it is only used for non-L1 fetches. This might not sound too impressive: AMD is still using a hashed perceptron prefetch engine for L1 fetches, which is goi

Yes, but for the previous few generations of transistor manufacturing, transistors' power consumption has not scaled down as well as their size. This is known as the failure of Dennard Scaling[0]. [0] https://en.wikipedia.or

But I was under the impression that Linux isn't suitable as a real-time operating system (RTOS)[1] (which Microsoft may very well not require for their IoT systems). So the Linux Foundation providing an alternative free kernel meeting

I was under the impression that the previous discussion got flagged because it was behind a paywall. Don't despair, I think we do care. :)

Neural networks aside, machine learning is often used for implementing prediction mechanisms in CPUs. Good examples of prediction mechanisms are: - Branch Predictor - Cache Replacement Policy - Memory Prefetcher - Schedulers

They mentioned in the article that the full cache of each die is available. Additionally, EPYC uses the same dies used in Ryzen. I'd look at earlier articles for Ryzen to determine latencies within a single die. So for whatever cores a

Even when discussing CPU caches, there are policies that can severely outperform LRU, specifically at the Last-Level Cache (LLC). LLCs often are exposed to access streams where the temporal locality (which is the assumption that makes LRU g

WiFi Direct differs from WiFi Awareness in respect to the presence of the access point. In WiFi direct, there is no access point, and the devices connect directly to each other. With WiFi Awareness, an access point serves as a middle-man, b

I think parametric design could be used here, but to what extent that would be useful, I'm not sure.

This is an interesting idea that has been explored before in VMS, an old operating system I believe competed with UNIX. VMS had a feature called CLE (Common Language Enviornment) [1] which defined calling conventions for computing primitive

USB-C and USB-3 aren't mutually exclusive. One describes the shape (Type-A, Type-C) of the connector. The other describes the speeds supported by the port (USB2, USB3, USB3.1).

This incorrect. While Gecko is not in its entirety going away, components of Gecko will be replaced with Servo's code. Such is detailed at Servo's roadmap. https://github.com/servo/servo/wiki/Roadma

The compiler for Rust still needs work in order to support the partial compiling required for typical IDE.

Just to clarify, unless you're a student/educator, Fusion360 is only free for 30 days....after that you have to pay.

Language feature-wise, I think python 3 has very little complained about it. The chief complaints about python I hear are anything to do with packaging software and multi threading the second of which will hopefully be fixed by 3.7. Obvious

Amen, for linux's copy-to-ram! I use the Slitaz distribution on my old Compaq computer from 1999, and wow! Even with only 384 MB of RAM, the system is blazing fast, all thanks to copy-to-ram!

To be clear, all this data sharing is on by default, but all the settings to turn this data sharing off do exist, they're just buried in settings (as they should be). Indeed, cutting ties with google is quite possible (just don't

Considering the philosophy of Python, how likely is it that this idea of return/parameter independence be introduced into the language (via a PEP or whatnot)?
