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.

How to Work With Astronomical Data: A Tutorial

By
Markus Pössel posted the review paper A Beginner’s Guide to Working with Astronomical Data . It’s a comprehensive overview of processing astronomical images, spectra, and catalog data with application software and the Python programming language. The paper also covers simulations and simulated data. The value of this paper is it distills into a single resource a lot of material available elsewhere, and provides guidance on getting started with the major categories of astronomical data.

Capturing and Annotating Images with Nimbus Screenshot

The Nimbus Screenshot & Screen Video Recorder Chrome extension is my favorite screenshot capture and editing tool. A screenshot annotated with Nimbus Screenshot on my Chromebox. I love the extension for its variety of capture options and annotation tools . I use Nimbus Screenshot on Chrome OS and it integrates well with the Google cloud as it lets me save to Google Drive. I use it for all the Chromebox and Chromebook screenshots I post to my blog and elsewhere. I live in the browser and the Google cloud, so It’s a good fit for my workflow. Although the extension can also do screen recording, I don’t take advantage of these features. Nimbus Screenshot is so handy I often fire it up for quickly annotating arbitrary images other than screenshots. I can add arrows, text, and other editable vector shapes such as ellipses and rectangles. In a pinch it doubles as a basic drawing app , often faster than opening a dedicated app. To annotate an image, select the Blank Screen

How to Limit Data Usage on Tethered Android Devices

Buying an affordable Wi-Fi Android tablet with no cellular data option is a way of getting it for even cheaper. It’s what I did with my Lenovo Tab E7 . The few times I need to use the device on the go, tethering to my Pixel 2 XL is straightforward to set up and use. But Android devices exchange a lot of data even when sitting idle. How to keep data usage under control? By tweaking the tablet’s account synchronization settings I can cut down on cellular data usage by two-thirds . Measuring data usage The first step is to get an idea of how much cellular traffic tethering generates, and how much I can save by playing with the system settings. I did two simple tests to estimate the amount of data usage to expect from the tablet while tethered to the Pixel 2 XL, which has a 4G Vodafone cellular data plan. In the Android settings of the phone, under Settings > Network & internet > Mobile network , a chart tracks how many MB of data have been used. In the tests I compar
