I wanted to write this post because I want the Fedora project to have better security throughout their operating systems. I believe the first step to doing that, is to use another memory allocator that mitigates heap memory corruption and use-after-frees, alongside lots of other features to harden one of the most important functions in all modern systems as far as I am aware. hardened_malloc[1], by the GrapheneOS project, fits this description perfectly. Using this benefits not just the Fedora project, but it will also push other distributions to using hardened_malloc, and then the Linux ecosystem will benefit as a whole from the provided security. Good security is an essential part of good privacy, so this will also benefit the privacy of all Linux distributions.

Given the above paragraph, I want you to promote this thread[2] to anyone who is interested in security and privacy. You can also help by testing hardened_malloc on your own Linux systems and sharing your results with me through any means of contact, so that I can replicate the behaviour and make bug reports where necessary. For that, please see this page[3] for my preferred methods of contact.

I don't think I'll be able to attract a lot of people with this post on my own, so boosting will be massively appreciated. Thank you for reading this until this point. This isn't my longest toot yet but I feel like this is my most passionate, as I deeply care about security, GrapheneOS and the Fedora project. Again, thank you! (^_^)

Newsletter: Crypto’s latest “infinite money machine” is the digital asset treasury company — a publicly traded firm that exists primarily to accumulate crypto. For a while, these stocks traded at hefty premiums to the underlying assets. But now, the trade is unraveling.

Digital asset treasury companies are running out of steam

Convincing traders to pay $2 for $1 of bitcoin worked — for a while. As premiums evaporate, an unwind could be painful.

Unexpected events and prosocial behavior: the Batman effect - npj Mental Health Research

Prosocial behavior, the act of helping others, is essential to social life, yet spontaneous environmental triggers for such behavior remain underexplored. This study tested whether an unexpected event, such as the presence of a person dressed as Batman, could increase prosocial behavior by disrupting routine and enhancing attention to the present moment. We conducted a quasi-experimental field study on the Milan metro, observing 138 rides. In the control condition, a female experimenter, appearing pregnant, boarded the train with an observer. In the experimental condition, an additional experimenter dressed as Batman entered from another door. Passengers were significantly more likely to offer their seat when Batman was present (67.21% vs. 37.66%, OR = 3.393, p < 0.001). Notably, 44% of those who offered their seat in the experimental condition reported not seeing Batman. These findings suggest that unexpected events can promote prosociality, even without conscious awareness, with implications for encouraging kindness in public settings.

East Bay Astronomical Society brings stargazing to Richmond waterfront

Grandview Independent @index@www.grandviewindependent.com

On a crisp, fall night, astronomers from the East Bay Astronomical Society gathered along the Richmond waterfront with locals ensconced in scarves and jackets, hoping for a glimpse of the stellar treasures a clear night sky has to offer.

The Astronomical Society hosted the stargazing event at Miller/Knox Regional Shoreline, in collaboration with the Richmond Library, drawing a lively crowd of about 30, including several families with young kids and even a pet or two.

Equipped with various-sized telescopes, laptops, and iPads, the volunteers worked nimblily in near complete darkness, with only a few red lights — typically used in astronomy events to preserve dark-adapted vision — illuminating the scene as they made adjustments and checked coordinates to provide a dazzling tour of stars, planets, and nearby galaxies.

Several computers displayed spectacular images, much to the delight of the junior astronomers, who happily bounced between the telescopes and the screens, asking questions and discovering the cosmos — some for the first time.

"I saw Saturn!" one boy said, beckoning to his parents to look through the lens and view the ringed planet for themselves.

Ross Bishop, a volunteer with the Astronomical Society, patiently guided those seeking a peek up to the telescope, which was fixed on the planet shining brightly through the lens. "What do you see?" Bishop coaxed. "Do you see a line? Those are Saturn's rings."

Bishop said this was the first time the Astronomical Society hosted an event in Richmond, but the view from the Miller/Knox shoreline proved to be a good one, lacking the intrusion of bright city lights.

"There's light pollution all over the Bay Area, which makes observing a little challenging, but this is a great spot," Bishop said.

A waxing crescent moon obliged observers by keeping its light minimal, helping to maintain a sharp focus on dimmer, more distant night-sky objects.

The society regularly partners with schools and libraries for evening star parties and other outreach events throughout the year, during which experienced astronomy volunteers bring out telescopes and other equipment to share close-up views of the Moon, planets, star clusters, nebulae, and galaxies. 

The East Bay Astronomical Society, which operates out of Chabot Space & Science Center, says its mission is to "increase the public's knowledge of astronomy and the space sciences, and introduce the infinite wonder and intrigue of the night sky to everyone." The society offers events, classes, and unobstructed views of the universe from the Oakland hills.

I would be remiss if I did not also mention that the support in the repo discussion tab for SQLite Data has been nothing short of outstanding. I am sure I am embarrassing myself with my newb questions, but responses have been not only helpful, but also very non judgmental. I am building a separate app in conjunction with going through the Modern Persistence series and am running in to all sorts of edge cases (for me) and I have really appreciated the quick responses. @pointfreecoPoint-Free Thank you.

I think that small earthquake I felt yesterday was my wife (journalism major, former editor of the Daily Illini in college, and occasional Tribune article contributor) telling me she called to cancel the Chicago Tribune. End of a era for her in a certain way.
