The only way to ensure privacy is something like PGP. Encrypt before you send. Heck you could even encrypt before you put the contents into a message body.
With self hosted, the messages themselves aren’t encrypted at rest and they are clear text between hops even if those hops support TLS in transit.
Ultimately the right answer for you will hinge on what your definition and level of privacy is.
If you don’t need the new features, they have made massive improvements to battery life—they’re just hidden behind the new features a s5 owner might not care about or need.
When I got my S6, I disabled:
Pulse OX
Always on display
wake on lift
noise monitoring
I also set the vibration to the lightest/most subtle mode.
When new, I was getting 56 hours.
I’m down to about 48 hours after just over two years.
Caveat: I use a Bluetooth HRM when working out. When I workout with the watch as the always-on HRM battery life is shortened accordingly.
It's going to be hard. If the recruiter/TA Specialist is good at their job they'll try to get you to give a "ballpark." They'll do anything to try to figure out the lowest offer they can make.
Do not give in.
Hold firm and ask what their offer is and go from there.
In one case their offer was double what I was expecting. It changed my life.
In other, their offer was just slightly under what I was expecting and I got what I hoped for with little effort and only a single back and forth.
There is one exception here: if they really want you and you are ABSOLUTELY sure you're out of their salary band for the position, you can wield your salary demands like a sword. I recently used my expected salary (which I knew the company wouldn't match) to negotiate a 4-day work week at their full time pay, with an extra week of vacation tacked on for good measure. Win win.
The focus here is primarily on removing captchas, and as such it's been integrated into Cloudflare (discussed here) and Fastly (here) as a mechanism for recognizing 'real' clients without needing other captcha mechanisms.
Fundamentally though, it's exactly the same concept: a way that web servers can demand your device prove it is a sufficiently 'legitimate' device before browsing the web.
Snaps I get, but Ubuntu? Aside from an asinine application process to get hired a Canonical, they did a lot to push for a more straightforward Linux desktop experience. Their time has passed, but cancer is a bit too much for me, considering all the fantastic offshoots.
Context: I came to Ubuntu from Gentoo. Debian before that and a brief flirt with the hot fantastic mess that was Mandrake when I first discovered Linux.
