T-Mobile has two new toggles that could affect your privacy, should you turn them off?

androidauthority.com Unknown 2025-07-28 17:18:45

Edgar Cervantes / Android Authority TL;DR T-Mobile has added two new privacy toggles: one for sharing certain financial information and another for fraud/identity theft protection. The first toggle allows T-Mobile to share your financial data with affiliates and marketers, while the second is meant to help detect fraud. You can disable both toggles in the T-Life app, and for most people, turning off the first is strongly recommended. T-Mobile and the other big carriers have a certain reputat

Lossless Float Image Compression

Back in 2021 I looked at OpenEXR lossless compression options (and I think my findings led a change of the default zip compression level, as well as change of the compression library from zlib to libdeflate. Yay blogging about things!). Then in 2023 I looked at losslessly compressing a bunch of floating point data, some of which might be image-shaped. Well, now a discussion somewhere else has nerd-sniped me to look into lossless compression of floating point images, and especially the ones that

The satellite internet space has only gotten more competitive in recent years, thanks to the rise of Starlink. Now that Amazon's Project Kuiper has successfully launched LEO satellites to kick off its own service, we only expect the conversation to grow from here. Despite the popularity of Starlink and the growing power of its 7,000 satellites, satellite internet is generally considered a last resort for home internet, due to slower-than-average speeds and the steep costs of equipment.
