The android captive portal settings are responsible for the annoying question mark beside the wifi icon. If the device can't connect to the captive portals, the question mark will appear. And at the latest Pixel 8a (android-os 14 I believe), it will also route the traffic through the carrier network which is clearly not desirable.

The settings can be changed by adb (https://gist.github.com/tonyseek/bc5b72197ddb15418c61406061720186):

$ sudo pacman -S android-tools

$ adb shell settings put global captive_portal_https_url <some_server_address>
$ adb shell settings put global captive_portal_http_url <some_server_address>
$ adb shell settings put global captive_portal_fallback_url <some_server_address>
$ adb shell settings put global captive_portal_other_fallback_urls

Booting to Rust by Eric Holk! It is just mind-bogglingly cool. What else can I say? His enhancement to Rust has been landed so it is time for me to try that out, in OS X. The setup of the toolchain could be a little bit challenging.

First and foremost, check out the latest Rust with win64 calling convention contributed by Eric Holk and build it.

Then prepare the cross linker.

$ wget http://ftpmirror.gnu.org/binutils/binutils-2.23.2.tar.gz
$ tar xvzf binutils-2.23.2.tar.gz
$ cd binutils-2.23.2
$ mkdir dist

An adaption of Leah Hanson's solution using Rust macros. The original go challenge goes here.

Compiled with Rust 0.5.

use core::task::spawn;
use core::pipes::{stream,Port,Chan,SharedChan};

There are some mysterious errors when trying to install miscellaneous package from octave-forge:

error: variable length array of non-POD element type 'Array<octave_idx_type>'

etc. This happens to homebrew-ed octave 3.6.4.

The issue seems to have something to do with clang, the default compiler homebrew uses to install octave. The solution for now is to use gcc instead:

$ export CXX=llvm-g++-4.2

Scipy Superpack is kind nice, but it seems to be inactive for a while and I want every thing under my complete control. So I went on installing them myself under homebrew-ed python.

Prerequisite

$ brew install python
$ brew install gfortran swig
