Apparently there is a C library for green (Go-like) threads called "libdill" or "libmill".

Slightly off topic, but I feel like calling an internet server running an OS "bare-metal" is a disgrace to what "bare-metal" originally and historically referred to, i.e. computer hardware without any OS. Maybe IaaS providers are running out of creative names that they are now polluting other techs' namespace?

I find it ironic that the "system" that you're writing Rust code for is entirely built in C :)

Depends on what do you mean by "work" here, which is a very vague term. One can argue that assembly doesn't teach you how computers work either because it "abstracts away" how transistors do their job. The point is: Depending on how deep you want to go in your understanding of the underlying system, there is always a level of abstraction that you have to settle on before building your knowledge on top of it.

Turns out that using C as the programming language for your project puts you at a very balanced spot in the abstraction hierarchy, where you don't have to learn processor specific instructions (well, not all of them) while requiring you to fully understand the "programmer's model" of the target processor. Keep in mind that learning C syntax alone doesn't do jack shit. You HAVE to be able to make full use of the tooling that a C toolchain provides. That means you need to learn things like memory layout (linker scripts, injecting code at a particular memory address / ISRs / faults and handlers), boot process (startup scripts, stack setup / data-segment initialization), kernel/user-mode and what not. So yeah, C is THE best language to learn your target system because of the level of optimization of the abstraction of the hardware that it provides you. Your code may be getting translated from a standard C architecture to the specific machine architecture; nobody's stopping you from learning how that process takes place. You could choose to learn the exact process, which C provides you complete tools for, or you could choose to ignore that process and let your compiler do its job. The beauty lies in the many possible levels of control.

I went from 10.3.3 to 12 directly. There doesn't seem to be any performance degradation.

As a developer who often needs to revert other developers' screwups (and sometimes my own): "git show COMMIT_ID -- somefile | git apply -R"

Been using it for 3 months only. It is a great routine; quick and effective.

They overextended in the enemy safelane. Maybe killing the enemy carry is #1 on their priority list :D

I understood what the project is about as soon as I looked at the first para of README. I guess it takes some patience and some topic related knowledge to get the most of READMEs. You can't really expect the software authors to explain everything in a README, like their audience are 12 year olds.

That, or declare them as packed.

I don't think there is any UB case that applies to the given snippet, or am I missing something? Treating unpacked structs as byte buffers is asking for trouble.

Its actually quite common for C programmers to create their own array type that knows its length, and use it in their projects. See this for example: https://github.com/antirez/sds

Can you please tell me what the battery life is on Ubuntu (with ACPI patch) vs Windows (with or without ACPI patch)?

Not eating healthy, and not doing enough exercise seriously messes up the brain functionality. It isn't apparent if you're young, but it keeps adding up until it explodes.

Did you apply the "non-official" patch for the deep-sleep? How well does it work? I'm actually waiting on Lenovo to release an official patch for it before buying this machine.

I just tried it, ran `time cat bigassfile.txt` test. How come it is slower after I enabled this? I have a mid-2013 MBA.

Think of universe as a reinforcement learning system. A system where its creatures are subject to a cost-function, the output of which is pain and suffering. You'll see how important it is for this world to evolve.

That's depressing.

Would love to hear it. I'm mainly concerned about the trackpad, wifi performance and power consumption.

I'm honestly thinking of switching to Thinkpad X1 Carbon now, but I HATE windows. And from what I've heard, Linux doesn't bode well with it. Anybody here Linux running on X1 Carbon?

As a guy who writes code for a living, one of my biggest fears is losing eyesight. Looking at this guy, I fear a little less now :) There is definitely a need for the tech to evolve for blind programmers.

I'm not from US, can someone explain how bad it is if anything that Zuckerberg said during the whole session proves to be false/lie/wrong later on? Is it considered perjury, or is perjury only specific for courts/legal matters?

This was fun. It somehow connected towels and croissants.

I really wish there was an easy way to change terminal line spacing in ANY of these distros.

I partly agree with you. But its a fact that you can't just start learning assembly if you have never learned C in the first place. So, young devs, please start learning C first.

Actually OP IS a customer. Upwork gets 20% out of his pay for being a glorified invoice generator.

Here is a C version of fizzbuzz if anyone has an interview tomorrow:

  #include <stdio.h>
  int main(void)
    {
      int i = 0;
      for(i=1; i<=100; i++)
      {
        unsigned int f = 0;
        if(i % 3 == 0)
        {
          f = 1;
        }
        if(i % 5 == 0)
        {
          f |= 2;
        }
        if(f == 0)
        {
         printf("%d\n",i);
        }
        else if(f == 1)
        {
          puts("fizz");
        }
        else if(f == 2)
        {
          puts("buzz");
        }
        else if(f == 3)
        {
          puts("fizzbuzz");
        }
      }
      return 0;
  }

How can you compare a programming language and a memory store? How are they even remotely comparable? Redis needs a syntax to exchange data with clients in a human-readable way.

Honest question: Why do you hate Redis?
