After my last post, I started thinking that perhaps systemd is designed to take advantage of multicore processors during startup. That might explain a lot. After doing a bit of googling on whether on not different CPU's can access RAM at the same time, since start up is all about getting things into RAM, it turns out probably not. In fact, one post indicated that a "boot CPU 0" is used for the whole startup. While it may be nice to have the system figure out what needs to run in what order, was it really that hard to execute things in lexical order and just name them appropriately. You pretty much have to do that math anyhow. In my little unit, my script needs the firewalld. Both my unit and the firewalld unit want "multiuser". Mine runs first and dies. I have to expressly tell systemd to run after the firewalld, which isn't a target. How is this easier? On a separate note, I found it really nice that neither the nft docs, nor the firewalld docs tell you how to persist changes. You have to read the firewall-cmd docs. Google told me that. Eventually. This is really poor too. I recently realized I can still use iptables even though the distro dumped me into nft. I don't really see an advantage to nft and I'm not even sure of firewalld's role. I'm thinking of going back to iptables. It is a complex thing to make things simple and a simple thing to make things complex. It looks like we've really gone down that rabbit hole.

I know that there are a lot of ways to have your online activity tracked. And, I thought I understood many or most of them. But, I tried out Gemini with the request, "write a two page article on Stoicism." The results were interesting and pretty good and give me an idea of what Gemini can do. A week, or less later, yesterday, I get an email from Facebook suggesting that I join the "Daily Stoicism" group. WTF. I never use Facebook and basically ignore their reminders on how many notifications or messages I have. AFAIK, there is no legal way Facebook should know what I am doing with Google, unless Google is providing them the information on a back channel. Am I missing something? Everything I know suggest that I would have had to visit a Facebook site sometime between my Gemini request and my receipt of an email from Facebook. Or possibly have visited a Facebook site before my Gemini request and not have directly entered a URL or used a bookmark in the interim. AFAIK, those things didn't happen.

Re: Privacy

OK. They have a cookie. I'm not at their site, they can't read it. They can't read other sites cookies either. That's the spec. I have to go to their site or use an associated site, to pick up the pixel. I didn't do that. There is no magic.:) Regardless of all that tracking, how would they know my query/request? To me, the only reasonable answer is that Google and Facebook share info behind the scenes, i.e. directly. As I understand it, a tracking pixel works because it is on the page you visit. It comes from, .let's say, Facebook's server, and they know the page that requested it. And they can get the info in the request header. To know who you are, whoever wrote the page has to have known who you are and encoded that in the pixlel somehow, maybe through it's name, or some other attribute. I haven't really been following a lot of the changes that have been made to store more information in caches on browsers. I'm wondering if there is something going on there. I really don't like the fact that browsers have taken this direction. Perhaps I need to look at those specs and see what is going on. On Wed, Feb 12, 2025 at 09:10:47PM -0800, Diego R.
