So, after your installation, what did you do next? share your good practices!
1. System configuration
eg, there are many service, which would you reserve. After all, there are some we do not need. The default installation, there are so many services, demons, and which we can stop.
Like akonadi, mysqld, there are so many process. it's a waste of system resource.
2. Software installation
eg, what is your good practices for install software,like which dir you choose for you installation(/opt ?)

As root you can run pkgtool to turn off and on daemons.

If you are not running KDE then you don't have to wory about akonadi. If you are running KDE and don't want your system indexed you can turn that off in the KDE system setting. Personally, when running KDE I turn off indexing and uninstall akonadi using removepkg.

I've have yet to see a package that didn't install to its default location. Very few use /opt.

I would set-up a firewall.

1. It all depends what you are doing with your machine.
2. Only use the Slackware package tools shipped with it.

I always run over to this page and go through it and do whatever I deem necessary within it, using it as a guild.
Slackware post install
https://docs.slackware.com/slackware:beginners_guide

then you can bounce over to this page and get yourself a firewall set up

Easy Firewall Generator for IPTables
"Slackware adaptation"

then after that if you want to can slide over to there and check out another install option for slackbuilds sbotools

and even go check out slackbuild.org

Install rkhunter and rkhunter --propupd then check before each update at least to see if anything changed usking rkhunter -c --sk. After update run rkhunter --propupd again. http://slackbuilds.org/repository/14...earch=rkhunter

I'm lazy. I use arno iptables firewall: http://slackbuilds.org/repository/14...bles-firewall/

I use defaults and make packages or slackbuilds for software.

Lynis is a good program for auditing your security: http://slackbuilds.org/repository/14.../?search=lynis

I chmod -x unwanted services in rc.d like rc.inetd. Use nmap and netstat to check for open ports.

If you use the Nvidia binary its important to keep the installer on your computer perpetually.

Use firejail with firefox: http://slackbuilds.org/repository/14.2/system/firejail/

I use a proxy and block the internet for 'users' and created another group to switch to if I want a program to have access to the internet.

Adduser

I build the latest LTS release of the Linux kernel. This is not always necessary if a Slackware release has recently been shipped.

I also like to get a nice dark theme for whichever window manager or desktop environment I happen to use.

Generate a new key for ssh. I like to use a different key for each machine.

If the system will be used for gaming, I install wine and steam.

I use Firefox for browsing most of the time. I install the following add-ons: HTTPS Everywhere, NoScript, Privacy Badger, and uBlock Origin.

For easy use of Netflix I install Chromium. With similar/same add-ons as Firefox.

Since version 52, you can stream Netflix on Firefox without any add-ons. It will however, at least on this box, run the CPU about 20 to 25 degrees Fahrenheit hotter than one of the chromium clones.

Yeah, I use KDE and I use removepkg akonadi, but I never enter the X window again.

After installation, I always do:
1) add user
2) set-up firewall
3) install sbopkg for easy installation software from SlackBuilds.org
4) recompile freetype to get nicer fonts (for more info: https://www.linuxquestions.org/quest...68/page34.html)

I'd recommend tools like sbopkg or sbotools only to people already familiar with usage of SlackBuilds, having read http://slackbuilds.org/howto/ and the pages it links to.

To get acquainted to Slackware there's a lot of interesting reading in http://docs.slackware.com/
