How does execute only memory disable privileged access never memory? The bigger problem I expect is the overhead of loosing PC-relative loads unless the hardware still allows these as instruction fetching related? Would you have to dedicate

It was a worthy successor building upon a great first game. The map and world design is top notch. Especially the switching between to interleaved time lines in the now abandoned manor and moving walls in the crazy inventors mansion. The ch

Red Faction's destructible maps lend themselves to a lot of creative gameplay, but the (late) game was far to linear. The engine made a lot possible, but to explore using explosives you had to exploit item duplication glitches or cheat

Modern hardware is too complex to understand and bootstrap for a single person even more so as a hobby project. These known unknowns can be a powerful motivation for someone who (partially) understands modern hardware to tinker with underst

I like the first paragraph of the README clearly stating that this is your research project instead of making a lot of grandiose claims.

Maybe, but it's not like the T1 or T2 had been successful designs. Idea 4x (or even 8x) SMT to hide L2 (and to an extend L3) like cache latency from an in-order architecture feels didn't work out. Not many users have only parall

Some of the old Cray machines only cached instructions and scalar data. Instead of a vector cache they used vector scratchpad registers and plenty of interleaved memory channels to keep up with the vector ALUs. That's one part of the d

One of the downsides having learned to code close to the metal on old CPUs is that you understood how that system worked and it‘s easy to assume assembler and the resulting machine code are the truth, but on modern CPUs that‘s a lie. A mode

I would argue that 6502 is a bad first ISA to learn if you want learn assembly. You‘ll spend most of your time fighting the quirks of this clever, but deeply flawed architecture. The idioms you learn to work around them don‘t translate to a

Given the more permissive license openrsync would be in a pickle if they stole the vulnerable GPL code and claimed to redistribute it under BSD license instead of reimplementing the protocol.

It applies to only to rsync and to not the (Open)BSD rewrite openrsync. openrsync intentionally doesn't reimplement all features so it's not always a drop in replacement.

by crest 2y ago
It's the same protocol and code implementing it just proxied over SSH instead of a local pipe or unix socket pair. It's a real world issue unless you trust the remote rsync process and the connection with your local user. So basic

One problem with your setup is that ZFS by design can't use a traditional *nix filesystem buffer cache. Instead it has to use its own ARC (adaptive replacement cache) with end-to-end checksumming, transparent compression, and copy-on-w

The main hurdle is hostile Linux kernel developers who aren't held accountable intentionally breaking ZFS for their own petty ideological reasons e.g. removing the in-kernel FPU/SIMD register save/restore API and replacing it

It's almost as if only Git is distributed, but people sold out to Github for convenience. Too bad Git lacks a distributed bug tracker and wiki system like Fossil. Guess Github has to fail a lot more for things to change.

You also have to account for the expected writes. Modern SSDs may perform better (over time) with TRIM, but if you just create (or leave) an erased partition to bump the effective over-provisioning even cheap consumer SSDs should outlast th

Use a lossy video codec if you need 300Mb/s for 240p streaming or just double check your math before making a fool of yourself with exaggerated claims.

That's why you get problems around 10Gbps, but simple 10Gbps optics and afaik all 1Gbps or slower optics don't use the "fancy" kind of signal processing because it wasn't needed. Their lower cut-off frequency should

Props to your kid. Doing the work yourself and then asking for a critique (however flawed) is a way better approach than most kids at that age would take.

It "just" doubled the memory bus width from 128 to 256 bit and cranked up the interface clock speed. I wonder what it means for the infinity fabric. Is it going to run at ~4GHz to keep up?

That's for both CPU, supposedly no-longer puny iGPU and the NPU. You'll get ≥80% real-world throughput for about half the power budget which is can easily be cooled in a 14" laptop that's thin for a gaming laptop without
