  • Cool. For my electronics work, IPA works wonders with silicone-based adhesives. (I’ll generally use a syringe and strategically drip it between the adhesive and the surface.)

    If, by chance, you run into any PET/PETG plastics, i think pure IPA can start to chew at those if enough heat is involved. It’s not nearly as dramatic as ABS/acetone though.


  • Edit: I just noticed this is a Lego community. Derp. Can anyone quickly identify the plastics that could be involved and I can correct or remove any words below. (I think acetone just got bumped into super-risky.) I am guessing Legos are going to be ABS in many cases, and acetone vapor tends to melt ABS.

    High purity isopropyl alcohol (99%) is generally my go-to solvent. It’s a small enough molecule to get in between most surfaces and glues. I wouldn’t know how <90% works since I just don’t use it. (Test first!)

    Another option is D-limonene.(commonly sold as Goo Gone) It’s another small molecule that works well.

    Acetone is the highest risk for plastics but is another good solvent. (Test first!)

    Otherwise, a razor blade, time and elbow grease is about your only other option.

    Its just complex

    When a security mechanism becomes more complex to manage than what it is supposed to protect, it becomes a vulnerability itself.

    If you had a minimal system that you built from the ground up yourself and wanted to only have that system function in very specific ways, SELinux would be perfect. I would go so far as to say it would be nearing perfection in some ways.

    Sorry, but in the real world, ain’t nobody got time for that shit. If you use auto configuration tools or pre-canned configs for SELinux on a system you are unfamiliar with, it’s more likely to cause application issues, create security gaps and will likely be shut off by a Jr. admin who really has no fucking clue what he is doing anyway.

    It’s just easier to keep your system patched and ensure basic network security practices anyway.

    It’s not impossible to manage these days. In the early days it was, but most everything is automagic now. If I am not mistaken, SELinux can be enabled to ‘log only’ which would give you data better handled by a HIPS anyway. (Don’t quote me on that.)
