  • University assumes every student has mobile phone svc & the will to share their number, so the rest are excluded from school resources that require 2FA by SMS

    When my university went 2FA, I told IT I didn’t want to use a phone, and they gave me a Yubikey. OTP-only, I can’t do any management, including to use it for other sites, and I couldn’t bring my own passkey/dongle/etc, but I was happy they had at least made a (zero out-of-pocket) allowance for people who didn’t want to give up their phone.

    But I think some of this loss of autonomy reflects maturing technology. I was in school just as the internet became mainstream. Email, usenet, definitely web, were cutting edge technologies that university geeks were basically making up as they went along. By the 2000s, they were everywhere. Mundane, even at scale. An email address was no longer a badge of geekdom, but just a thing that everyone had to have and a burden for the university to provide. It’s the IT equivalent of landscaping.

    The places where universities are still leaders are hard to see, because they haven’t been commoditized for sale on Amazon or as ad-bait on Google. 3D printing came out of universities. Stabilized and semi-autonomous drones. I don’t know what the new hotness is that will be everywhere in 5-10 years, but I’m pretty sure it’s some grad student just dicking around with a cool thing today.




  • To me, the nonstandard port is mostly nice for reducing log spam from scripts. The risk is that using a nonstandard port lulls one into a false sense of security and overlook good sshd practices. Good sshd practices will prevent the script-kiddies just as well as the non-standard port, while a non-standard port will not challenge a targeted attack. And, if you interact with multiple servers, it can be inconvenient to remember a different port for each one.




  • I’ve come to love building workbenches from 2x4’s. They’re (reasonably) cheap, soft enough to work easily, and you can essentially use mass to compensate for intrinsic rigidity. Maybe add plywood shear panels in strategic places. Even 1/4" plywood shear panel will beat most brace structures.

    2x4s are cheap enough to try a design for a while & throw it out (or downgrade it to patio furniture) if it doesn’t work. Soft enough to just plane a millimeter off the top when it gets beat up. If you invest in expensive hardware, move it to the new iteration. I’ve got like three of them now.
