  • Depends what he’s looking for. I think Onshape (browser based CAD) has a free version. Your data is public though unless you go with a paid version.

    If he wants a free Linux CAD there is FreeCAD and a few others.

    If he is attending a university, as some retirees do to audit courses or enrich life, then Siemens NX (what GM, Stellantis, SpaceX, etc use) have an academic license for around $100 a year. It is now Windows only based, unless you run Linux headless version, but if you use any version NX12 or below there is a GUI LInux version that runs on REL or SUSE (or openSUSE since it shares SUSE binaries)







  • Best thing would be for you to just search what exploits a firewall protects against because its not just open ports. I would link stuff but you are discounting what I linked earlier that Ubuntu ships with firewall off; by nature the most popular distro is less secure because of that.

    So no point me wasting time if you aren’t interested in it.

    Edit: sorry if tone seems bad, its not intentionally that way.


  • To answer all your questions I’d need some time, I’d have to go back to the 100s of hours of 2.5admins and security podcasts. But to clarify an exploit doesn’t have to be an open service especially if you aren’t running a firewall. Some bombard your network adapter into buffer overun etc, but network traffic is handled by the kernel stack. A good firewall drops packets instead of letting them all into the public interface and kernel TCP stack. Where CVE stuff can happen.

    I’m not saying Linux can’t be hardened , but because it is user editable and not locked down like Mac, you have a lot of things people can alter (or not alter) by hand or packages that can leave you open.

    There’s a reason we have AppArmor and SELinux, yet some don’t bother to use those tools.

    There was something with discord? Discourse? screen sharing that used x11 forwarding, and was on by default. I want to say Ubuntu. When it was news I checked by SUSE install and thankfully its disabled by default. But also the reason Linux distros are moving to Wayland because X11 is a security problem.

    Ubuntu ufw off by default https://documentation.ubuntu.com/server/how-to/security/firewalls/index.html






  • I get your point, but since people claim Steam is a monopoly, then by that logic they have a large swath of data on what counts as a gaming machine to the user base.

    I get its not going to compete with a watercooled watt sucker, but that doesn’t seem to be the majority.

    As a person that has gamed since 1983: Up until recently I was gaming on a 2013 dell mobo converted to a Core V21 case (that’s a lot of rewiring conversion --thanks dell), and using a CAD GPU.

    Then work bought us new laptops with RTX cards. So graphics have improved for me.

    Both of those are not hardcore gaming PCs, and this steam machine will probably outperform them.

    My point being these were valid systems for gaming by a gamer. Not everyone needs an F1 car to enjoy the ride to work😀
