Maybe a strange question, but do you often have simultaneous opposing opinions on books or series that you read?
Not too long ago I read Peter Watts' Blindsight, and it has many thought-provoking ideas about conscience, the human brain, and alien life. Yet it is wrapped in a mediocre sci-fi action movie script that is difficult to follow and stops making sense toward the end. So I cannot say that I exactly liked or disliked it.
And just now, I finished Ann Leckie's Imperial Radch series, and it feels like books 2 and 3 (Ancillary Sword, Ancillary Mercy) are entirely separate story from book 1 (Ancillary Justice). The latter books are okay for what they are, but do not live up to the style, scale, and pace of the first book, and leave some of the concepts entirely unexplored. So once again, I cannot exactly say that I loved the series.
Any other books that left you with similar dual opinions?
Seeing lots of dislike for Matrix lately. Hosted a Synapse server for many years, never had issues with encryption keys, but have to agree that Element the company (formerly Vector, but they now control the protocol too?) rolls out more new things than they fix old ones. E.g: Element X is slower and calls are not backwards compatible (!). Synapse server keeps getting some (corporate-looking) auth stuff added while on-boarding and registration for plain accounts on self-hosted servers is still a pain. To give them credit, Element app is consistent across platforms (for purposes of convincing people and troubleshooting), and bridges work pretty well.
But it seems any self-hosted solution has its can of worms.
XMPP, being old, implements all modern-expected functionality as extensions, and servers are not guaranteed to have them (common argument). Spam was an issue as well (but simplicity of the on-device and server database allows easy message and attachment deletions). iOS clients for XMPP are meh and require integration with Apple push servers (Snikket and Monal do that, but for how long?)
Tried SimpleX years ago, loved the idea, but it was going through growing pains. In the same vein as metadata leaks for Matrix and XMPP, if you host your own SMP server with a few users, that exposes some info vs using default servers (along with thousands users)
