The CPU/hardware related bugs surfacing the last couple of years have mostly been fixed by adjusting the software that is run. Sometimes only by disabling certain features of a CPU or patching the microcode in the CPU itself.
The issue with this is that by fixing these issues features got disabled and workarounds had been introduced that lowered performance. Dramatically so for some use-cases.
By how much? Well it really depends on your CPU and use-cases. But maybe you want to try yourself. If you want to know the most current parameters to pass to your kernel on boot-up to disable all the performance impacting fixes, go here:
It is not recommended to have this in productive use – as you can imagine. Those bugs where fixed for a reason.
I’ve recently written about the privacy and data security state of this blog and starting today all content is being provided encrypted.
Bless the wonderful Let’s Encrypt project!
As of early 2019 I’ve started to bring back my content output stream to this website/weblog.

Apple has started to force developers that want to develop and publish on the MacOS and iOS platform to enable two-factor authentication.
Two-factor authentication (also known as 2FA) is a type, or subset, of multi-factor authentication. It is a method of confirming users’ claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are.wikipedia
When I just got around enabling it for one of the apple accounts I’ve got there seems to be a much much higher security barrier in place already…
That’s probably some sort of zero-factor no-authentication. I guess. Anyway: Kudos to Apple for finally forcing people to minimum standards. Properly integrating the second factor will make this so much simpler for users. Apples ecosystem solution already is quite well integrated.
Have you switched all your daily used services to two-factor authentication yet?
