attributes the invention to George Bosworth, ephemerons are a kind of
weak key-value association.Thinking about the problem abstractly, consider that the garbage
collector’s job is to keep live objects and recycle memory for dead
objects, making that memory available for future allocations. Formally
speaking, we can say:An object is live if it is in the root setAn object is live it is referenced by any live object.This circular definition uses the word any, indicating a disjunction:

Scientists have discovered how Toxoplasma, one of the most common parasites in humans, hacks the immune cells of its hosts so that it can ride them around the body with alarming speed, reports a new study. The research reveals new secrets about this pernicious parasite, which reproduces in cat hosts and has infected at least one third of the global population, and sheds light on how other infectious diseases spread in humans and animals. Toxoplasma is widespread in warm-blooded animals and can be dangerous in some cases—especially for pregnant women and fetuses—though most people who carry the pathogen do not develop any harmful symptoms. The parasite is a public health concern as well as a scientific…

It’s never a bad time to revisit John Carpenter’s 1988 classic They Live, a hilarious sci-fi thriller that skewers the inequality of the neoliberal era and offers an iconic depiction of capitalist ideology.
The truth behind capitalist advertising, per John Carpenter’s 1988 They Live. (Alive Films, 1988) It’s almost Halloween, the time of year when every good socialist watches They Live (1988). The cult classic about the politically revealing sunglasses that expose the monstrosity of our overlords and the brutal alien society they’ve made never fails to satisfy upon repeat viewings.
Though it didn’t do well on initial release, They Live is one of John Carpenter’s ever-more-revered films, because of its extraordinary…

I’ll start this post with a bit of whimsy before alarming you with the sense of doom portended by the stakes involved with last week’s oral argument at the US Supreme Court in Andy Warhol Foundation for the Visual Arts v. Lynn Goldsmith.
In this case the Warhol Foundation is trying to get SCOTUS to overturn a terrible decision at the Second Circuit that found Warhol’s Prince prints to not be a fair use of a photograph earlier taken by Lynn Goldsmith. This case is not just a big deal for the Warhol Foundation, which manages Warhol’s art portfolio, but for anyone else who may ever wish to make a fair use of any copyrighted work that…

War fever in Washington has reached such a pitch that even mild calls for cease-fire talks, as House progressives articulated in a now-retracted letter, are now beyond the pale. That’s dangerous at any time, let alone when nuclear tensions are high.
Representative Pramila Jayapal speaks with reporters on Capitol Hill in Washington, DC. (Jabin Botsford / the Washington Post via Getty Images) Even before Russia invaded Ukraine, liberal discourse about the issue had veered in a deeply unhealthy direction, with any suggestion that the US should exercise restraint in managing the antagonistic US-Russia relationship casually labeled treasonous, authoritarian — even covertly doing the work of the Kremlin. As earlier episodes of…

Have you ever had that weird feeling of letting your mind wander on a car trip, then not remembering anything about your drive when you arrive at your destination? Or perhaps you’ve struggled to fall asleep as your brain cycles endlessly through intrusive thoughts? Do you ever get “in the zone” while deeply engaged in an activity, like playing music or sports? These are some of the common experiences that have inspired a team of scientists to dramatically reimagine the evolution of consciousness, which is a state of awareness that humans (and perhaps some other animals) possess about their minds and the world. Led by Andrew Budson, a professor of neurology at Boston University and Alzheimer’s…

The ACLU asked the Supreme Court to rule that laws prohibiting specific kinds of boycotts are unconstitutional,
after one federal appeals court ruled to the contrary.

The authoritarian campaign to prohibit boycotting Israel has put the
US in danger of broad-spectrum plutocratist authoritarianism.

Fair Use says it is OK to use this image because this is a commentary on it. Right? U.S. Supreme CourtThe internet has opened access to culture. Billions of webpages build on the art, images, music, film, television and writing of the past. This explosion of content leads to tough questions over ownership of creative work and exclusivity of use. The highest court in the land may soon try to better define the limits of free use, or the right to remix previously published work. On Oct. 12, 2022, the U.S. Supreme Court heard oral arguments in Andy Warhol Foundation for the Visual Arts, Inc. v. Goldsmith. The case addresses when artists or writers may…

PostgreSQL 15 has now the capability to output logs in JSON format! PostgreSQL 15: logging in JSON The freshly released PostgreSQL 15 introduces a lot of new features and improvements, but one, according to me, is going to change the way our favourite database is monitored: the capability to log daemon status in JSON.

Essentially, the log_destination configuration parameter now has another enumerated value: jsonlog. When this value is added to log_destination, PostgreSQL will start to emit JSON structured logs.
Here it is a simple configuration example:

% grep log_destination /postgres/15/data/postgresql.conf
log_destination = ‘stderr,jsonlog’

and this is how the log directory appears right after the configuration has been reloaded:

% sudo -u postgres ls /postgres/15/data/log -1
postgresql-Fri.json
postgresql-Fri.log

Clearly the…

Early Saturday morning, a Florida man and his teenage son were arrested after allegedly shooting at and nearly killing a woman sitting in her car after receiving a Ring doorbell camera alert. After a neighbor stopped by Gino (73) and Rocky (15) Colonacosta’s front door to drop off prescription medication accidentally delivered to the wrong address, the Ring surveillance camera began bombarding their phones with alerts. The pair grabbed .45-caliber handguns, went outside looking for a burglar, and found a woman sitting in her car on her phone. Gino pointed the gun at her and ordered her out of her car, but she escaped in her car believing she was being carjacked. The pair allegedly shot…

An hour of interwar Halloween music: Spooky season listening from Centuries of Sound.

An hour of interwar Halloween music (permalink)
Through his delightful Centuries of Sound project, JM Errington is producing an hour-long mix of music for every year since 1853 – the dawn of music recording itself. Interspersed with these “annual” mixes are some thematic ones. His latest, “Halloween Between the Wars,” is an hour of spooky interwar music and radio/film horror excerpts:

A developer came to me a week ago with a project they’d been working on for over a year. The proposition of what they offered and the importance of what it would mean to historical software at Internet Archive was so compelling that within 48 hours, we’d announced it to the world. The site is DISCMASTER.TEXTFILES.COM, and within its stacks lie multitudes of previously hidden software treasure, and a directed search engine that makes it a top-notch research tool. More than a fascinating site, though, it represents some philosophies regarding the Archive’s stacks that are worth exploring as well. The first thing that strikes a visitor to the site is either how strange, or…
