Moreover, I've been running Linux for decades now, both in my personal laptop and at work, and Ubuntu has been (mostly) frictionless for me. I'm not an average user, of course, but for most users a friendly distro would work just as well as Windows (browsing the internet, using whatsapp web, watching movies). In some cases I've had a better user experience with Ubuntu than with Windows or OS X, namely seamlessly inst…

I only tried Ubuntu, a few month ago. For the day or two spent with it: - multi-language support requires a lot of work to get to the same point as macos. In particular I use third party shortcut mappers to get language switching on left and right command keys (mimicking the JIS keyboards, but with an english international layout). That looks like something I’d have to give up on code myself. - printer support is not…

Ah, Apple. When you can no longer innovate, just start removing features and call it simplicity...

Another way to look at it is that Apple is making it harder to run the system in an insecure fashion. You may not agree with that decision, but I certainly appreciate how Apple is looking out for the safety and security of the user. Tangent: as much as some developers hate that the only way to distribute apps for the iPhone is through the App Store, as a user I consider that walled garden of apps to be a real securit…

It seems like there is a lot of confusion here as to whether this is real or not. I've been able to confirm the behavior in the post by: - Using a new, random executable. Even echo $rand_int will work. Edit: What I mean here is generate your rand int beforehand and statically include it in your script. - Using a fresh filename too. Just throw a rand int at the end there. e.g. /tmp/test4329.sh I MITMd myself while rec…

  RAND_FILE="/tmp/test-$RANDOM.sh";
  time_helper() { /usr/bin/time $RAND_FILE 2>&1 | tail -1 | awk '{print $1}'; }  # this just returns the real run time
  echo $'#!/bin/sh\necho Hello' $RANDOM > $RAND_FILE && chmod a+x  $RAND_FILE;
  echo "Testing $RAND_FILE";
  echo "execution time #1: $(time_helper) seconds";
  echo "execution time #2: $(time_helper) seconds";

  Testing /tmp/test-24411.sh
  execution time #1: 2.32 seconds
  execution time #2: 0.00 seconds

Just get a proper antivirus and it will probably disable the built-in security suite for you

While making your computer even worse?

I would love to switch back to Linux but Apple's Retina displays are absolutely beautiful and there is no way I could enjoy going back to anything with noticeably lower pixel density on a laptop. I'd like to be told I'm wrong, but as far as I know it's not really possible to recreate a comparable high pixel density experience under Linux on a laptop.

Two years ago, I helped a friend install Ubuntu Linux on a Retina Macbook Pro, and it worked like a charm. If you're looking for a new laptop entirely, there are loads of 4K+ Linux-compatible laptops out there (ThinkPads are probably your best bet).
