Vinoth (Datacenter security)

I am Vinoth, from San Diego. I currently work on Datacenter HW security at OpenAI. I used to lead the silicon security architecture and silicon security operations teams at #Google. Before that, I worked on mobile silicon security at #Qualcomm.

Much of my professional work so far has been about improving the security of #Pixel and other #Android devices. I will mostly talk about #mobilesecurity, #androidsecurity and #infosec.

I sometimes invest in seed stage start-ups, primarily technology companies. My portfolio includes Modumate, Akido Labs, kia.ai, Zendoc and Zeoauto. If you are building something cool, hit me up.

@timbray @mpjgregoire As someone who speaks both Tamil and English, I'm not surprised. Tamil words have a finer resolution than English. There are four different words for "love" to use in different contexts, two different words for "hot" (taste vs temperature), two different words for 'sour' (lemony vs slightly numbing taste), many many words for different relationships which English collapses under a few words like uncle, aunt etc.

@lorenzofb Related gripe: You need to pay extra $100 for the Pro edition if you want to keep the BitLocker keys out of the cloud. Basic privacy should not be a "premium feature" that you pay extra for.

@feld @david_chisnall @paco David nails it. Also, encryption at rest makes it possible to retire storage devices after End-of-Life without having to worry about data theft after retirement.

@nelson I am blind. Seeing people who think I'm not worth the effort fill my timeline with AltBot generated AI stuff that isn't even accurate in lots of cases.

Human alt text is always better, because it doesnยดt focus on ocular seeing. Seeing people think, and AltBot was designed around that notion, that blind people must compensate for missing "eye-seeing", but that's not the case. I am interested in the meaning of an image to you, its maker or publisher.

Again, human alt text is better, also because it strengthens reciprocity between seeing and blind people. AltBot doesn't but it makes seeing people believe they have done their bit for accessibility. In actuality, the reverse is often true.

!!!!!!!!!

Me: We don't want a rebellion sparked by 'Taxation without representation'. Do we?

@interfluidity The nice thing about democracy is that the electorate always get what they deserve. Which also means that, on a long enough time horizon, democracy is self-correcting.
