Installing Python 3.7.4 on Raspbian

As of July 2018, Raspbian does not yet include the latest Python release, Python 3.7.4. This means we will have to build it ourselves, and here is how to do it.

1. Install the required build-tools (some might already be installed on your system).

Whole Module Compilation Optimizations: Why these terms are sometimes misleading

When you look up how to compile swift faster for debug builds, people very earnestly give advice that seems contradictory: you should "try using the whole module optimization flag," and also "never use whole module optimization for debugging". [^1]

This is confusing because some of us are using these two general words:

compilation: "turning text into an executable program"

slendidev

#!/usr/bin/bash

putsc() {
    echo -en "\e[34m :: \e[0m $@"
}

putscl() {
    putsc "$@\n"
}

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

• Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
• Simple - This solution has few dependencies, readily available packages and minimal configuration.
• Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43

Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]). 
The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch. 
Following are the changes that I made to make it work.

$ sudo apt-get update
$ sudo apt-get install lirc

# Add the following lines to /etc/modules file
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=17

UINavigationBar on iOS 11

NOTE This note is written based on Xcode version 9.0 beta 6 (9M214v) and its simulator binary.

iOS 11 changes UINavigationBar a lot, not just only for its large title, but also the internal view hierarchy and lay outing views are changed. This is a small note about UINavigationBar behavior on iOS 11, mainly focusing on migrating the application to iOS 11.

Lay outing views

UINavigationBar has been using manual lay outing until iOS 10, so all its content views like titleView has been directly child view of the UINavigationBar. However, since iOS 11, it is using auto layout with bunch of layout guides to lay out its content views in its own internal container view, _UINavigationBarContentView.
