How I Fixed the Fingerprint Sensor of My Pixel Phone

By
Some time ago the failure rate of the fingerprint sensor of my Pixel 2 XL Android phone got worse. The device was failing to recognize my fingerprint more and more. Two simple things I did fixed the issue, here they are in case you experience something similar.

The first was to clean up the fingerprint sensor. I had been using the phone for a year or so and the sensor had likely gathered significant dirt.

Another thing I did was to scan more fingerprints of the same finger to increase the recognition accuracy. 2-3 scans of the same finger should be enough, try more if there is little or no improvement. You may want to scan also a different finger.

Using a Bluetooth Keyboard on Android

Two years ago I bought a cheap Bluetooth keyboard from Amazon.it. At €14, it was mostly an impulse buy for exploring mobile typing on the go and in similar settings , such as workstations with reduced desk space. My FREALL 7INKEYBD-BK Bluetooth keyboard. I initially used the keyboard with the Android tablet and smartphone I had, a 7” Lenovo Tab E7 and a Pixel 2 XL. I later repurposed the keyboard for the devices I replaced those with, a Lenovo Tab M8 HD 8” tablet and a Pixel 4 XL smartphone. Despite the simplicity of operation, it took me some trial and error to figure out how to pair the keyboard with an Android device and what keystrokes insert the characters I need, such as accented letters when writing in Italian. Moreover, I realized I never blogged about my experience with the unit. So I’m posting these notes in case you come across the same or similar keyboards. The keyboard The keyboard is a cheap, compact, plastic chiclet unit that comes with a small foldable stand for a ta

An Intel 8080 Assembly Suite in Python

A blog post I stumbled upon made me start a new project, crank out lots of Python code, slip down a rabbit hole of arcane and fascinating corners of retrocomputing, and overflow with fun. The project is Suite8080 , a suite of Intel 8080 Assembly cross-development tools comprising an assembler and a disassembler. I developed it in Python entirely with Replit . At over 1,500 lines of code , it’s my second and largest Python project after Spacestills , a NASA TV still image viewer of about 340 lines of code. A hello world Intel 8080 program running in the z80pack CP/M emulator on Crostini Linux. I assembled the program with asm80, the Suite8080 assembler. Why did I write software for a half-century old CPU? This is the story of how I got started with Suite8080, how I developed it, the challenges I faced, and what I learned. Let’s start before the beginning. Background I’m a hobby programmer and a Python beginner, not a professional developer. To practice with the language, I finally set o

How to Add Code Syntax Highlighting to Blogger

By

On my blog I always wanted to format source code in Python and a couple more languages, but couldn’t find a convenient way. Until I read a tutorial on adding syntax highlighting to Blogger blogs like mine. The Blogger post composer actually provides the monospace Courier font that may be used for source code, but it works well only for inline text . If I apply the Courier font to a block of code, the composer renders each line as a separate paragraph. This leaves too much vertical space that makes the code look ugly. A workaround is to switch to the HTML view in the composer and wrap the block within <pre> ... </pre> tags, which insert the correct line spacing. However, the code doesn’t stand out on the page and there’s room for improving its scannability and visual impact. Fortunately, Blogger is an old dog I can teach new tricks to, like the setup the tutorial I found presents. A Python code snippet with syntax highlighting rendered by highlights.js in a post of the Moo
