Linux Kernel Gets Another Option To Disable Spectre Mitigations (zdnet.com)
Despite being more than one year old, the Meltdown or Spectre vulnerabilities have remained a theoretical threat, and no malware strain or threat actor has ever used any in a real-world attack. Over the course of the last year, system and network administrators have called on the Linux project for options to disable these protections. A report adds: Many argued that the threat is theoretical and could easily be mitigated with proper perimeter defenses, in some scenarios. Even Linus Torvalds has called for a slowdown in the deployment of some performance-hitting Spectre mitigations. The Linux kernel team has reacted positively towards these requests and has been slowly adding controls to disable some of the more problematic mitigations.
[...] The latest effort to have mitigations turned off -- and stay down -- is the addition of the PR_SPEC_DISABLE_NOEXEC control bit to the Linux kernel. This bit will prevent child processes from starting in a state where the protections for Spectre v4 are still activated, despite being deactivated in the parent process.

I gladly advocate forgoing vaccinations for endemic and childhood diseases, because the vaccines are so effective. They reduce culling, and long term cause harm to humanity by saving individual children.
New harmful or detrimental mutations in the human genome that in themselves are not enough to kill someone, but in combination with diseases like measles have a statistically significant higher morbidity are allowed to spread undiluted into our gene pool. These saved children have children of their own, where they otherwise would have died. When some ignorant anti-vaxxer says that vaccines cause autism, they may very well be right, but for the wrong reasons. It's not the vaccine itself, but that children who might have died now live to reproduce. If children with autism have any lower survival rate if they catch measles than children without autism do, no matter how small that difference is, by vaccinating against measles, the prevalence of autism will increase. There's a significant correlation between vaccinations against childhood illlnesses and the next generation being sicker from other illnesses like autism, asthma and spectrum disorders.
And we get superbugs. Through vaccination against endemic diseases, we instigate an arms race, where new and worse strains appear, which we have little protection against, unlike the milder versions that outcompeted any bad ones because we didn't wage war on them.
