I'm working on a bug for two days. Not finding the root cause. We schedule a reboot on a hardware device but it is not beign performed. Using TR198 protocol after a long chain of different processings on data. I'm 80% sure that code breaks somewhere but can not find it. adding more logging info on debug level.

Our product still uses Zope #bytheway . We have a new version of the product without Zope but the older one still uses it. Amazing tech behind it.

Was frustrated by a problem in our "program" for 3 days. No troubleshooting workek. Asked for a colleagues help and ... the problem was in nginx configs! #silly_me

Have finished my free LPIC1 booklet / videos. I believe content-wise its good but I'm not brave enough to share it with the world (say here or reddit). Have to do it today! I promise :D

Lets see what will happen today

Spent the last 3 days in a wedding in Southern Iran. Danced at the beach and enjoyed great friendship & culture.

When learning the programming, seeing a mature program with all the loops and conditions might look confusing. You might wonder how the programmer has coded all of this? Here I'll show you how a programmers might solve a challenge in its most basic / simple form and then add loops and conditions to make it more general / userful.

One problem with clients such as Gossip is the "local data". I have 3 computers and when I follow someone on Nostr on one, I do not have her followed on others (or other Clients). Understandable from the tech point of view but frustrating. At the moment partially solved it by moving my Gossip data dir to Dropbox managed directory but I think we need an standard export / import NIB. #nostr #nib

In the last video of my LPIC series, we are talking about Encryptions. First we will have a look at the concept of Key pair (Public & Private) encryption and its usage in SSH (including passwordless logsin): Then I will cover the ssh tunnels. Seldom seen but super useful in everyday life (including X11 Forwarding): And we will finish by seeing how the `gpg` tool lets us encrypt & sign data:

Based on my understanding, my nostr publishing / following depends on my cilent. 1. My client has the list of people I follow and check / show them. 2. My client is configured to post to a specific relay and if I use another client with a different relay, some of my "follower" might miss me For both there are ways, specially for the 2nd one. But I think there should be NIPs to "fix" this. An standard way to export/import the list of people I follow on my client.
