It is not recommended to split up your seed words[1]. Do not try to build your own scheme. If you want to store your keys geographically it is recommended to use multisig. You can also use a passphrase (13th/25th word) that can be stored separately from the 12/24 seed words[2].
Where I work we've recently upgraded many PostgreSQL servers from 9.x/10.x/11.x to 14.x.
A very cool PostgreSQL feature is that, if you install a second instance on the same server, it will by default use a different path and port to run the second instance.
root@example:~# pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
14 main 5433 online postgres /var/lib/postgresql/14/main /var/log/postgresql/postgresql-14-main.log
Now you can dump and import databases on the second instance and test your applications with the new version. If it all works as expected, use pg_upgrade[1] to migrate everything to the new instance and switch the ports after the migration.
I have only done this migration process on Debian systems but in my experience it worked fantastic!
Indeed! HATop is great to show the status, traffic, HTTP codes, errors or number of connections. It is also very simple to enable/disable HAProxy backends, for example:
hatop -s /var/run/haproxy/example.sock
Use the arrows to select a backend server and press:
F9 - Enable a backend server (Status: UP)
F10 - Disable a backend server (Status: MAINTENANCE)
I did the same, visted Berlin a few weeks ago. It was indeed nice that I could take any S-Bahn or U-Bahn without checking the times or zones.
I hope they’ll continue with this type of ‘unlimited’ tickes. If only during peak summer/winter months. I guess a lot of people would gladly pay more for such unlimited (no worry) tickets.
> Homes aren't heated with nuclear power, they're heated with gas. Industrial processes don't run on nuclear power either, they run on gas.
I'm glad that there are still people who understand this. In the Netherlands 90% of the homes[1] still run on natural gas and that's not something we can "simply" replace. It is possible and will eventually happen but it will take years if not decades.
And that's just homes in the Netherlands. Take a look at the global energy mix[2] how much the world still depends on gas.
The switch should have started years or decades ago. If 90% finds it economically beneficial to keep using fossil fuels for heat the economic incentives are faulty and needs to be updated to move to other alternatives. Heat pumps, bio fuel, waste heat from industry, there are probably plenty of other sources. And of course, energy management, with well insulated houses.
Does every layperson have to adopt stocks or commodities? Are these also dead if a layperson does not adopt it?
