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.

A NASA TV Still Frame Viewer in Python

I wrote Spacestills , a Python program for viewing NASA TV still frames. The main window of Spacestills running on Replit. As a hobbyist wishing to improve my Python programming skills, for some time I’ve wanted to work on learning projects more substantial than code snippets , throwaway tools, or short scripts. Spacestillschecks several boxes. The problem domain is one of my primary interests, space exploration. At about 350 lines of code, it’s a non-trivial system with a GUI. It accesses the network to download data from the web. Finally, the program relies on a few Python libraries. About the program Spacestills periodically downloads NASA TV still frames from a web feed and displays them in a GUI. The program allows to correct the aspect ratio of the frames and save them in PNG format. It downloads the latest frame automatically and gives the option to reload manually, disable the automatic reload, or change the download frequency. As a learning exercise, Spacestillsis a basic pro

How to Add Code Syntax Highlighting to Blogger

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

4 Things Tutorials Don't Tell You About PyPI

Time to celebrate! I published my first Python package to PyPI, Suite8080 . It’s a suite of Intel 8080 Assembly cross-development tools. It’s in early development, misses some tools, and is rough around the edges. But it works, does something useful (if you’re into retrocomputing), and I’m having ridiculous amounts of fun with this hobby project. The Python Package Index (PyPI) website. The celebration is wearing out and I’m about to resume the work to complete and improve Suite8080, yet something still bugs me. Although it’s well known PyPI is unforgiving for good reasons, the package publishing process is not as straightforward as the tutorials make it seem . I run into a few unexpected minor bumps none of the guides mention. It’s not that the tutorials aren’t good, they are. I recommend the Real Python article on publishing a package to PyPI . But the authors of these guides are so experienced, and probably so detached from the challenges beginners face, they may not be aware some i
