This weekend I’m thinking about upgrading my laptop to the beta of Bionic Beaver, Ubuntu 18.04 LTS.

Right now it’s I’m still using Xenial Xerus Ubuntu 16.04 LTS, which will be obsolete when Bionic Beaver comes out.

Normally I’m in no rush to upgrade, as I use the XFCE Window Manager which hasn’t changed much in the past decade and a half but Xenial Xerus is too old that they’ve not backported QGIS 3.0, especially the new labeling engine.

IMSI-catcher

"An International Mobile Subscriber Identity-catcher, or IMSI-catcher, is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users. Essentially a "fake" mobile tower acting between the target mobile phone and the service provider's real towers, it is considered a man-in-the-middle (MITM) attack. The 3G wireless standard has some risk due to mutual authentication required from both the handset and the network. However, sophisticated attacks may be able to downgrade 3G and LTE to non-LTE network services which do not require mutual authentication"
