For 'cool stuff' dev work, Debian or Ubuntu. For large scale, enterprise stuff, an rpm based version like RHEL or SLES or CentOS. There's plenty of mid size shops running Ubuntu LTS versions now as well. Being a sysadmin is a different mindset from being a developer. <br><br>It getting harder to do security analyst stuff as the research side requires craptons (metric and english) of esoteric knowledge and access to gear for testing. Being a testing specialist requires extensive knowledge of tools and ability to work with and understand CVE data.<br><br>I'm not gonna touch databases other than to say Linux has a huge collection of the best of breed (and Oracle is still unable to have a type IPv4 address!).<br><br>And web servers....<br><br>And embedded systems...<br><br>And huge scale HPC systems (my world)...<br><br>There's no end (to the madness :-).<br><br>So, yes, do a raspberry pi but also do an old desktop box as a server. Make sure you can put 2-4 drives in to learn about multidrive systems (that really is good knowledge!). Have some networking gear, dumb and manage switches (the ability to mirror a port to a packet capture machine is really useful).<br><br>Microcenter has off lease boxes for cheap. Several thrift stores have old desktop PC gear for really cheap. Never keep the winders os. Wipe that crap and never look back. That's why I now have 2 laptops for work 🤦♂️. (I told them I would wipe it and install Linux)<br><br>Have a lot of fun!<br><br>Ask a lot of questions! We are glad to help.<br><br><div class="gmail_quote">On January 9, 2021 1:59:40 PM EST, Mark Ogilvie via Ale <ale@ale.org> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
