Johns Hopkins Computer Science prof Professor Peter Fröhlich grades his students on a curve: the highest score on the final gets an A and everyone else is graded accordingly. Read the rest
Human beings have a weird, poorly-understood ability to pick a single conversation out of a noisy room, it's called the "cocktail party effect" and while its exact mechanism isn't totally understood, researchers do know that vision plays a role in it, and that being able to see the speaker helps you pick their words out of a crowd.

Ben Gurion university's Mordechai Guri is a master exfiltrator, a computer scientist who's devised a bewildering array of innovative techniques for getting data off of "airgapped" computers that have been fully disconnected from any kind of network. Read the rest
Marketing companies frequently "anonymize" their dossiers on internet users using hashes of their email addresses -- rather than the email addresses themselves -- as identifiers in databases that are stored indefinitely, traded, sold, and leaked. Read the rest
Berkeley's "Foundations of Data Science" boasts the fastest-growing enrollment of any course in UC Berkeley history, and now it's free on the university's Edx distance-education platform. Read the rest
Dale Lane's Machine Learning for Kids project uses extensions to the popular Scratch programming environment to teach the basics of machine learning to children. Read the rest
Robot law pioneer Ryan Calo (previously) teamed up with U Washington computer science and law-school colleagues to write Is Tricking a Robot Hacking? -- a University of Washington School of Law Research Paper. Read the rest
In An Empirical Analysis of Traceability in the Monero Blockchain, a group of eminent computer scientists analyze a longstanding privacy defect in the Monero cryptocurrency, and reveal a new, subtle flaw, both of which can be used to potentially reveal the details of transactions and identify their parties.

A group of Chinese computer scientists from academia and industry have published a paper documenting a tool for fooling facial recognition software by shining hat-brim-mounted infrared LEDs on the user's face, projecting CCTV-visible, human-eye-invisible shapes designed to fool the face recognition software.

Many people worry that 3D printers will usher in an epidemic of untraceable "ghost guns," particularly guns that might evade some notional future gun control regime that emerges out of the current movement to put sensible, minimal curbs on guns, particularly anti-personnel guns. Read the rest
New York's cyclists and bus-riders are certain they're being slowed and endangered by an epidemic of illegal lane-obstructions from delivery vehicles, taxis and Ubers, but policymakers have refused to do anything about it, saying that the evidence is all anaecdotal. Read the rest
By design, data placed in the blockchain is visible to everyone in the world and can never be removed; everyone who mines bitcoin makes a copy of the blockchain, and so any illegal content stashed in the blockchain ends up on the computers of every miner. Read the rest
Machine learning is often characterized as much an "art" as a "science" and in at least one regard, that's true: its practitioners are prone to working under loosely controlled conditions, using training data that is being continuously tweaked with no versioning; modifying parameters during runs (because it takes too long to wait for the whole run before making changes); squashing bugs mid-run; these and other common practices mean that researchers often can't replicate their own results -- and virtually no one else can, either.

Machine learning models use statistical analysis of historical data to predict future events: whether you are a good candidate for a loan, whether you will violate parole, or whether the thing in the road ahead is a stop sign or a moose. Read the rest
Richard J. Ridel's all-wooden, mechanical Turing machine uses the smallest set of data elements capable of computing any calculation: 0, 1 and blank; it was inspired by Ridel's viewing of The Imitation Game. Read the rest
"Idea-instructions" bills itself as "An ongoing series of nonverbal algorithm assembly instructions", with a half-dozen illustrations of popular computer science concepts covered to date; the latest covers Public-Key Crypto, one of the most important and elusive concepts from modern crypto. Read the rest
The creation of "public ledgers" -- like blockchain, popularized by Bitcoin -- requires "consensus algorithms" that allow mutually untrusted, uncoordinated parties to agree on a world-readable, distributed list of things (domain names, transactions, title deeds, etc), something that cryptography makes possible in a variety of ways.
