Detecting child abuse pictures is not incompatible with end-to-end encryption if the detection is done locally. Facebook (or other messenger app owners) could train a good classification model to detect child abuse pictures on large servers

The examples given in the article are hardly "genuine, spontaneous citizens". Of course, the important question is to quantify bots vs. genuine--though the following examples are pretty clear-cut. Quotes from the article: > The

Thanks for the reply. Such introspection tool would be useful indeed--it seems already possible to do some inspection by hand with https://fluxml.ai/Zygote.jl/latest/adjoints/#Gradient-Reflec... Anyway, great

Say you receive an offer for a specific position in a specific department and hope to negotiate a better salary. Aggregated data averaged across all fields, all universities and all ranks is not useful. However, the salaries of recent hires

The take-away from this is that - several (maybe most) state universities in the US publish the salaries of their professors. Some state universities publish comprehensive (creepy?) granular data, e.g., a spreadsheet with each row displayin

After the post is saved (but hidden until the user solves ReCapcha) you can look at the database and analyse what's happening. Did ReCapcha turned away an interesting post by a legit user? What is the ratio of spans versus legit users?

Requiring to solve ReCapcha after may be more sensible than the usual use case where ReCapcha is required before any interaction. Let the user create account, let the user create first comment/post, save it somewhere but hide it, t

Microsoft could auto-install a Microsoft branded chromium with native uBlock integration in the next windows update. That would be entertaining to watch. On a related note, if OSes were shipping uBlock powered browsers by default, removing

10 trillions is not much in the realm of "conjectures that have only large counterexamples". The proposition 𝑛^17+9 and (𝑛+1)^17+9 are relatively prime is not true for all n, the first counterexample being n=8424432925592889329288

An algorithm with complexity O(n^{999}) is polynomial but but not more useful than an exponential algorithm on any practical problem. If an NP solver comes out, it may not practical (at first or for any practical purposes). The polynomial c

I am wondering if any cost-analysis studies have been done to assess the trade-off between lengthy end-of-life terminal care and the corresponding cost. Doctors seem to make such decisions all the time; but we may have at some point to disc

The goal of the post is to compress an already trained network. An more ambitious related goal is to perform the training of the network with at most 10% (or other small percentage) of the network weights being nonzero at any time during tr
