The world’s first hack: the telegraph and the invention of privacy (2015)

“By the turn of the century, business users were concerned about privacy, and cable companies were therefore keen to ensure they knew anything sent by cable was secure,” says John Packer, honorary curator of the Telegraph Museum and a lecturer from the museum’s previous life as a telegraphy teaching school. The Eastern Telegraph Company, with a global hub in Porthcurno, absorbed a stream of companies connecting the British Isles to everywhere from South America to India, forming a near-monopoly over international security had spread across the globe, but it wasn’t until a rival technology appeared that communications privacy was fully articulated as a concept within the public imagination. When John Tawell travelled from Slough to Paddington, his pursuers were able to use the telegraph to send a message faster than the train he rode on.

No paper, no PhD? India rethinks graduate student policy

No paper, no PhD? India rethinks graduate student policy

PhD students in India will no longer be required to publish articles in academic journals before they are awarded their doctorates, if the country’s higher-education regulator adopts recommendations from a committee of researchers. The University Grants Commission (UGC) currently requires PhD students to publish at least one article in a peer-reviewed journal and present two papers at conferences or seminars before they submit their doctoral thesis for marking. The committee suspects the publishing requirement has contributed to a flourishing of poor-quality journals that offer to publish papers quickly for a fee, without providing services such as editing and peer review, says Padmanabhan Balaram, chair of the committee and a biochemist at the Indian Institute of Science in Bengaluru.

Instagram influencer with 2M followers fails to sell 36 t-shirts

Instagram influencer with 2M followers fails to sell 36 t-shirts

An Instagram influencer, Arii, with 2,6 million followers has posted (now deleted) how she failed to launch her online clothing brand which she needed to only sell 36 t-shirts online to kick start. Despite her millions of followers on Instagram she couldn’t convince a mere 0.00001% of them to buy her t-shirts which raises questions about whether her followers are bots or humans but more importantly, whether likes and comments are a good signal for online sales. Secondly, and more importantly, just like Arii, startups need to stop focussing on vanity metrics like number of followers, trending on social media, views, likes, RTs etc. and focus on the real things that keep their businesses afloat like sales.

Reid Hoffman: You Can’t Just Sit on the Sidelines

Reid Hoffman: You Can’t Just Sit on the Sidelines

So I did a summer internship at Xerox Park, where my job was building a simulator for a multiagent learning system. But the thing that I learned from philosophy was an ability to articulate theories crisply, which led to an ability to express crisp theories of human nature, which aligns with some of the most interesting things around , like consumer internet and entrepreneurship. But understanding — here is the way the world could be, here is the theory of human nature that you’re playing into in order to create that world, and here is that kind of combination of psychology, sociology and economics together with what’s possible in technology — that combination was enabled much more by philosophical thinking.

NY Schools Will Test Facial Recognition on Students over Objections of State

NY Schools Will Test Facial Recognition on Students over Objections of State

A New York school district will move forward with its facial recognition pilot program next week, despite an explicit order from the New York State Education Department that it wait until a standard for data privacy and security for all state educational agencies is finalized. Lockport implied that its facial recognition system should not be a privacy concern because it “does not compile information on and track the movements of all District students, staff and visitors.” Johanna Miller, director of the education policy center at New York Civil Liberties Union, which has investigated Lockport’s rollout of facial recognition technology, called the system “a colossal waste of taxpayer dollars and energy that should be spent educating kids.”

Scaling to 1M active GraphQL subscriptions on Postgres

Scaling to 1M active GraphQL subscriptions on Postgres

An alternative approach is to refetch all the data for a particular query (with the appropriate authorization rules for the specific client). Data loader type patterns can alleviate the problem, but will still query the underlying Postgres database multiple times (reduces to as many nodes in the GraphQL query from as many items in the response). However, considering that we have all the application-user level session variables available at the API layer, we can actually create a single SQL query to re-fetch data for a number of clients all at once!

More evidence that autism is linked to gut bacteria

More evidence that autism is linked to gut bacteria

It was prompted by earlier work in which Dr Krajmalnik-Brown and James Adams, a colleague at Arizona State, sequenced the of gut bacteria from 20 autistic children to discover which species were present. They collected bacteria from the faeces of both neurotypical and autistic people (who ranged in their symptoms from mild to severe) and transplanted these into hundreds of mice. Most of the young mice harbouring gut bacteria from autistic human donors showed features of autism themselves.

Why Was Mini USB Deprecated in Favor of Micro USB?

Why Was Mini USB Deprecated in Favor of Micro USB?

By way of example – a number of Motorola’s “Razr” cellphones used micro-USB receptacles, thus allowing the designs to be thinner than would have been possible with a Mini-USB receptacle. A significant driver to a common USB connector is the new USB charging standard which is being adopted by all cellphone makers. Large list of cellphones that use micro-USB receptacle

A few more images allowing comparisons of a range of aspects including thickness, area of panel, overall volume (all being important independently of the others to some for various reasons) and retention means.
