but, i was trying to block access to a specific server from my network when it clicked that i could potentially block ad servers that way and i'm actually surprised by how well this worked:
google's near monopoly on ads on the internet means this is almost a total block, and it keeps the processing off my overloaded and expired chromebook. the difference in performance was immediate.
i have a compaq laptop from the late 90s that works perfectly well but cannot play youtube videos because the ad servers on google/youtube crash it. i've moved from a windows 98 pc to an early xp laptop to a 2010ish expired chromebook for my tv just because the ad servers on google have forced me to upgrade. it's really quite ridiculous; none of these machines have broken, they all work, and they can all stream video, but i can't get past google's ad infrastructure with the first two.
the chromebook is a better option for integration with youtube anyways, granted, but i wonder if i might be able to save the laptop with this little trick.
