sigjuiceon Building an Intelligent Emacs

I just got started on Go and I am quite satisfied with eglot for now.

sigjuiceon Ask HN: What do you do with your homelab?

Lol. Same here. I had to get rid of my gear to make space for actual furniture :)

sigjuiceon Apple removes Python 2.7 in macOS 12.3 beta

At least for me, homebrew emacs isn’t that useful. It is terminal-only.

sigjuiceon SSH Bastion Host Best Practices

Is finer grained control over TCP forwarding possible? e.g. allow forwarding only to certain TCP ports?

sigjuiceon Should you use Let's Encrypt for internal hostnames?

Yes, the scope of the leak would be limited. But if a privkey.pem file from one of the hosts of my network is leaked, how do I “immediately” know which host the leak came from?

Could this be turned into a USB Ethernet adapter for regular computers?

sigjuiceon Ask HN: What Operating System are you running on your main machine?

Ubuntu 20.04 at work and macOS at home.

sigjuiceon Redo: A recursive, general-purpose build system

Looks like gcc does not plan to do this https://gcc.gnu.org/bugzilla/show_bug.cgi?id=28810

sigjuiceon Redo: A recursive, general-purpose build system

If a /usr/include/x.h were to appear, wouldn't that have lower priority than the x.h in the current directory and therefore not change the build?

sigjuiceon Redo: A recursive, general-purpose build system

make doesn't really understand C or C dependencies, but the compilers usually do. Here is a minimal example that will take care of dependencies by passing -MD -MP to gcc or clang. The dependencies (*.d files) get generated as part of the normal gcc/clang invocations. There is no separate dependency generation step.

  $ cat Makefile
  CFLAGS := -MD -MP   
  hello: hello.o x.o y.o
  -include *.d

  $ echo '#include "x.h"' > x.c
  $ echo '#include "y.h"' > y.c
  $ touch x.h y.h
  $ echo 'int main(void) {}' > hello.c

  $ make
  cc -MD -MP   -c -o hello.o hello.c
  cc -MD -MP   -c -o x.o x.c
  cc -MD -MP   -c -o y.o y.c
  cc   hello.o x.o y.o   -o hello

  $ touch x.h

  $ make
  cc -MD -MP   -c -o x.o x.c
  cc   hello.o x.o y.o   -o hello

sigjuiceon Why Is C Faster Than Java (2009)

Is there a term for this phenomena yet? "if another language is being discussed, Rust must be forced into the discussion, no matter how tenuous the connection"

Rustrusion

sigjuiceon List of 4,248 open source programming languages

The title is misleading. I don't see "open source" mentioned anywhere on this page.

e.g. it is very unlikely that all the Basic variants listed here are open source.

sigjuiceon Raspberry Pi holds its own against low-cost ARM NAS

Is there a specific Synology NAS model with this restriction?

I happen to have Western Digital drives in my Synology DS920+.

sigjuiceon Which programming language or compiler is faster

The phrases "compiled language" and "interpreted language", despite their widespread use, are not particularly sound concepts. There are plenty of languages that have both compilers and interpreters.

sigjuiceon Which programming language or compiler is faster

What does it even mean for a language to be faster?

sigjuiceon Apple Helps Asahi Linux

Is there another interview that goes into the details of Apple's boot setup goals?

https://www.youtube.com/watch?v=Hg9F1Qjv3iU&t=3785s

In this one, Craig Federighi says “We’re not direct booting an alternate operating system. Purely virtualization is the route. These hypervisors can be very efficient, so the need to direct boot shouldn’t really be the concern.”

sigjuiceon Apple Helps Asahi Linux

It is a huge assumption that Apple is explicitly doing anything for the benefit of Asahi Linux. Apple likely has their own reasons for doing whatever they are doing.

sigjuiceon How to use dig

dig can also be used to make mDNS queries.

sigjuiceon Lego has designed a set that can't be taken apart

Looks complicated. Just stack the 2x1 sandwich on a larger place. Pop off the topmost 2x1 with the brick separator tool. Then pop the second one off the larger plate. My 5-year old just showed me :)

sigjuiceon Business Essentials

It depends on one's preferences and circumstances. I got a new M1 MacBook recently and I took my time setting it up from scratch.

A few years ago, I had my MacBook stolen. I was up and running within a few hours after getting a new Mac and restoring from my Time Capsule. Dealing with the aftermath of a car break-in (thanks San Francisco!) and a new computer at the same time was going to be a bit much for me.

sigjuiceon Why can't Facebook App allow to select text in it's iOS App?

It isn’t great because it adds an extra step, but on iOS 15, parts of text can be copied from screenshots.

sigjuiceon Writing a “bare metal” operating system for Raspberry Pi 4

Yeah, C is really easy to interface with assembly language.

Doesn't necessarily have to involve assembly!
