Silicon Valley is shutting down speech loopholes. Latest target: live content

substack.com — On January 6th, Jon Farina, photographer and videographer for Jordan Chariton’s Status Coup outlet, captured horrifying images. At the Capitol, a pro-Trump mob tried to burst into the building, and a police officer who attempted to intercede was caught in a door. He cried out in pain, but the crowd was indifferent, chanting, “Heave, ho!” as they tried to break in. Farina, in the middle of the physical mayhem as photojournalists often are, caught the scene up close while 30,000 people watched the live feed. LOOPHOLES, 7

Navy “UFO Patent” Documents Talk of “Spacetime Modification Weapon”

thedrive.com — In our continuing investigation into the bizarre inventions of Dr. Salvatore Cezar Pais, an enigmatic aerospace engineer who works for the U.S. Navy, The War Zone has just obtained a wide range of documents detailing experiments that the Naval Air Warfare Center Aircraft Division (NAWCAD) conducted to test the core concepts and technologies underlying his seemingly out of this world "UFO patents." These same patents were vouched for by the head of the Navy's aerospace research enterprise who cited Chinese advances in similar technologies as one of the reasons why the Navy was filing them.  SPACETIME, 9

Show HN: I made an alarm clock

stavros.io — It’s a brand new year, which means I should really start writing a new post. I’ve been wanting to for a while, but we’ve been in lockdown for two months now and Google Analytics is the only indication that I’m not alone on the planet, and most of that is bots anyway. I’ve decided to take a page out of the book of my friend, James Stanley, who both does cool things and actually writes about them, so I’m starting to document all my projects again. ALARM, 12

How we made Typerighter, the Guardian’s style guide checker

theguardian.com — The Guardian’s style guide was originally published in 1928 as a physical book, and is available to everyone on our website. Over time, it’s grown bigger and more complex, containing guidelines on important topics that we want to get right. Last year, for example, we updated it to more accurately describe the environmental crisis facing the world. In short, our style guide is ever-expanding, and it changes to reflect our times and values. How do journalists writing and editing content keep up to date? TYPERIGHTER, 17

Postgres scaling advice

cybertec-postgresql.com — So, you’re building the next unicorn startup and are thinking feverishly about a future-proof PostgreSQL architecture to house your bytes? My advice here, having seen dozens of hopelessly over-engineered / oversized solutions as a database consultant over the last 5 years, is short and blunt: Don’t overthink, and keep it simple on the database side! Instead of getting fancy with the database, focus on your application. Turn your microscope to the database only when the need actually arises, m’kay! When that day comes, first of all, try all the common vertical scale-up approaches and tricks. Try to avoid using derivative Postgres products, or employing distributed approaches, or home-brewed sharding at all costs – until you have, say, less than 1 year of breathing room available.
