[Links of the Day] 04/06/2020 : XoR filters, SIMD + Json , Online tracking and publisher's revenues

• Xor Filters :  Xor filters are great as they provide a fast and small version of bloom or cuckoo filter. However, there is some key difference. Xor filters require all the members of the set be provided upfront. While, Bloom filters allow adding members, but not removing them and finally Cuckoo filters allow removing members. So just pick what's best for you.
• SimdJson : nice performance leveraging the CPU feature. However, the lack of support for null entry feel like cheating ( and probably crash with the most common real-life payload)
• Online Tracking and Publishers' Revenues : The authors demonstrate that the use of cookie only represent a 4% increase of revenue vs non-cookie for an advertiser. Which brings question the differential benefit between ad publisher like Google and Facebook vs the advertiser. Bringing into question why should advertiser pay for the loss of privacy that only benefits their platform provider.
