- Modern Operating Systems, 5th Edition by Andrew Tanenbaum (of MINIX fame) and Herbert Bos (https://www.pearson.com/en-us/subject-catalog/p/modern-operating-systems/P200000003295/9780137618880) is the latest edition of a solid graduate-level textbook on operating system concepts. It may also be beneficial studying the source code of existing operating systems. I recommend starting with smaller, simpler... - Source: Hacker News / about 14 hours ago

Those other flashy distros like mint and ubuntus are designed with rich people with very fresh machines in mind, they don't care if you have an AMDx4 or core2duo or even 32bit older machine. Even Mint and ubuntu people will tell you, if you have an old machine with little ram, use antiX. It still works very well with machines not even released yet, buy one in May 2024 and I "guaranty you" antiX will run fine. ... Source: 6 months ago

The memory_order_relaxed explanation on the kernel.org documentation heavily implies (never explicitly) that the direct memory load is implicit in the barrier(so by preventing it's reordering we are also forcing a LOAD from main), and that THIS specific barrier (relaxed) is what we NEED for these type of scenarios, so I am not entirely sure if a loadLoadFence() would prevent the hoisting... Maybe it will prevent... Source: 8 months ago

I am a bit confused, there are three sites: * https://nanos.org/ * https://nanovms.com/ * https://ops.city/ And I am not sure what "thing" I am using. Is there some disambiguation? I know is OPS is the orchestration CLI, but I am confused at the difference between Nanos and NanoVMs. What should I call the section of my README that deals with this tech? Currently gone with Nanos/OPS but I am confused. - Source: Hacker News / 3 months ago

Forgot to mention this but https://nanos.org is also related with https://nanovms.com (to deploy unikernels) and ops.city (which handles the package distributions), so it's like a whole ecosystem. I wonder why Alpine linux won over this though? - Source: Hacker News / 3 months ago

I work with https://nanos.org && https://ops.city - we can run thousands of these on commodity hardware. - Source: Hacker News / 6 months ago

Unik was just a build tool that utilized other projects like Rump, Mirage, IncludeOS, etc. It's now dead since Solo pivoted a very long time ago to service mesh/api gateways. The GoRump port they use was from us and then we realized we needed to code our own from the ground up for many reasons so we wrote https://nanos.org (runs as a go unikernel in GCP). - Source: Hacker News / 7 months ago
