m6.12xl are 48 vCPU systems. 25 million cores is a hilariously huge amount of compute to use to run a site of twitter size, which I guess does point to how much tech debt they have…

Pretty sure Google hasn't used 'bitshift puzzle' interview questions for ~10y now. It really is just a meme thing from long ago. My interview there ~6y ago was basically the same a…

The problem here is really just general flaws in capitalism. The main thing I hate about ads is the broken corporate incentive -- companies want to earn as much as possible and the…

Each ad serve is not worth that much to start with, facebooks CPMs are about $7-8, so they are getting $0.007 per serve with extensive targeting. The falloff is something around 10…

If you remove pay models, a vast majority of the internet will just disappear. (I think you) in a previous comment mention that it is 'cheap' to run a site, which is generally true…

It is really for people coming in 1-2 days a week. Very impractical to have 5x desk space for 5 people who all come in one day a week.

My google team didn't even _have_ a PM for most of my tenure there.

Google actually pays Zurich engineers more than Bay Area, something like +15% IIRC. I was close to moving out there at one point and know a few people who did.

The most common causes of false ad clicks on the web isnt fraud but unintended maliciousness. Eg. there are extensions around that 'click' and load pages or click through posts to …

People do click them but unsurprisingly the rate is pretty low. Often times ~0.5% - 1% for a reasonably well targeted ad. So 1 in 100-200.

Ads are not just charged by click. Some campaigns pay by impression served and some pay by conversion. It depends on what the advertiser is trying to accomplish. Pepsi might pay pe…

While sometimes this does get tricky with resources that are clearly owned or associated with multiple things, often times a resource only has one real owner and it is unambiguous.…

A lot of people make TL within 5-7 years, its not that uncommon (although we are talking about top 1-5% of programmers). Saving $1MM on west coast salary in 10 years is really doab…
