i saw the sky glow
Aurora borealis visible in night sky, displaying vibrant pink and red curtains of light above a residential area. There are: dark silhouettes of trees, a parked vehicle in the foreground, and a street lamp illuminating the left side of scene. A long exposure photograph capturing a feint aurora in the sky above a suburban street with streetlights, power lines, and silhouetted trees.

saw some cool mushrooms
A vibrant yellow fungus with ruffled, wavy edges grows on the side of a fallen log in a wooded area. The fungus has a coral-like or lettuce-like appearance with multiple overlapping lobes in shades of golden yellow and pale orange. It appears to be a shelf or bracket fungus emerging from dark, weathered bark. The background shows a forest floor covered with fallen autumn leaves, with tree trunks visible among dappled sunlight filtering through the canopy above. The photograph is taken at ground level, creating an intimate perspective of this forest mushroom in its natural habitat. A cluster of yellow-orange fungus growing vertically from a piece of decomposing wood on a forest floor. The fungus has delicate, ruffled petals or lobes that form a rosette-like structure, with colors ranging from pale yellow to peachy-orange, with some darker orange spots scattered throughout. The texture appears thin and wavy, almost translucent in places. The fungus emerges from dark, weathered gray wood that shows signs of advanced decay with peeling bark. The surrounding ground is covered with fallen autumn leaves in various shades of brown and tan. This overhead perspective shows the intricate layered structure of the fungus as it fans outward from its central attachment point on the log. An overhead photograph of a cluster of pale orange to yellowish mushrooms growing on decaying wood. The mushrooms have fan-shaped or shelf-like caps with wavy, ruffled edges, arranged in overlapping tiers. The caps display radial ridges or gills running from the center outward, with coloring that ranges from cream to peachy-orange, and some darker spots or discoloration visible. The mushrooms are growing from weathered, grayish wood, surrounded by fallen leaves, plant debris, and scattered foliage on the forest floor. A cluster of shelf fungi growing on decaying logs in a forest setting. The fungi display overlapping, wavy bracket-shaped caps with distinctive coloring: rich golden-yellow to orange-brown on top, transitioning to cream and pale yellow tones on the undersides. The layered, ruffled edges create a cascading effect as multiple fruiting bodies grow in tiers along the weathered, gray-brown wood. The fungi appear fresh and vibrant, with a slightly leathery texture visible in their rippled surfaces. In the background, green foliage and dark tree trunks create a dappled forest atmosphere, while fallen leaves and forest debris are scattered on the ground below. The composition captures the fungi at eye level, emphasizing their sculptural, shelf-like growth pattern characteristic of polypore mushrooms.

i've been playing this new game. it's pretty fun, but the skill system is can be annoying at times
Screenshot of Math Academy. Under the “Learn” tab, a drop-down summarises completion across three tracks: Mathematical Foundations III (58 %), Linear Algebra (20 %), and Multivariable Calculus (9 %). Within the Multivariable module, six sub-units appear with topic counts and tiny horizontal progress bars—e.g., “Vector Functions and Vector Fields (27 topics),” “Multivariable Functions (50 topics),” and “Multiple Integrals (36 topics).” The layout offers a concise snapshot of breadth, depth, and remaining workload for each cluster. Screenshot of Math Academy. An expansive, densely connected graph depicts how individual topics feed into one another. Each oval node represents a concept (e.g., “Stokes’ Theorem,” “Triple Integrals in Type I Regions,” “The Divergence of a Vector Field”); arrows indicate prerequisite flow. Selected nodes—rendered in blue—mark topics already covered, while the majority in grey remain pending. The web-like structure highlights the course’s logical sequencing. Screenshot of Math Academy. A progress widget shows 9 % completion, with an estimated finish in mid-August. Left column: total XP earned (1 896 XP), a yellow daily bar (88 / 50 XP), and a weekly histogram (694 XP) broken down by weekday. Right column: a queue of locked items—“Unit Tangent Vectors” (67 % through), “Quiz 9,” and three subsequent lessons—each labelled with its XP reward (12-16 XP). Together the panels track accumulated effort, pacing, and upcoming material. Screenshot of Math Academy. A “Gold League” header indicates the current competitive tier with four days left in the weekly cycle. An inset menu lists the nine colour-coded tiers—Diamond (top 5 %), Emerald (top 11 %), Ruby (top 18 %), Sapphire, Platinum, Gold, Silver, Bronze, and Iron—conveying both hierarchy and percentile cut-offs. Below the menu, a scrollable table shows mid-board rankings: positions 14-21 display usernames, XP totals ranging from 44 XP to 10 XP, and a red “Demotion Zone” section begins at rank 22 for participants with 0 XP.

"perplexity" I wonder what Leo XIV's favorite model is
Excerpt from https://www.detroitcatholic.com/news/chilean-cardinal-gives-insight-to-the-conclave-that-elected-pope-leo-xiv During the meal, Cardinal Chomalí asked the new pope why he had chosen the name Leo XIV. "He told me he is very concerned about the cultural shifts we are living through, a Copernican revolution really -- artificial intelligence, robotics, human relationships," the prelate said. "He was inspired by Leo XIII, who in the midst of the Industrial Revolution wrote 'Rerum Novarum,' launching an important dialogue between the church and the modern world." The new pope believes the church has a vital role to play in today's moment of "perplexity," Cardinal Chomalí added. "There is a revolution happening, and it must be addressed seriously. The church can contribute through its moral authority and also its academic strength."

Although it seems amazingly unlikely, it appears to be a different guy who is into math and religion, since the pope didn't get a D.Phil, his dad's initials aren't "R.W.", and there's no indication he was ever at Oxford

Universal Antivenom May Grow Out of Man Who Let Snakes Bite Him 200 Times Scientists identified antibodies that neutralized the poison in whole or in part from the bites of cobras, mambas and other deadly species Snake-venom-exposed hyperimmune donor as a source of broadly neutralizing antibodies A hyperimmune human adult male donor was identified with a documented 18-year history of 856 self-immunizations to venoms, spanning 2001–2018 (Figure 1C). Documented self-immunizations included mambas (D. polylepis, D. viridis, D. angusticeps, D. jamesoni), cobras (N. kaouthia, N. haje, N. melanoleuca, N. nivea), rattlesnakes (C. atrox, C. scutulatus), water cobras (N. annulata, N. cristyi), and taipans (O. scutellatus, O. scutellatus canni), as well as the Eastern coral snake (Micrurus fulvius), common krait (Bungarus caeruleus), banded krait (Bungarus multicinctus), tiger snake (Notechis scutatus), and Eastern brown snake (Pseudonaja textilis). Hypothesizing that this repeated exposure to diverse venoms may have selected for broadly reactive antivenom antibodies that recognize conserved epitopes shared across the venom toxins of multiple snake species, we sought to isolate such broadly neutralizing antibodies from the immune memory of this donor.

i don't mean to downplay o3's geoguessr capabilities, which are quite astonishing, but "Any photo outdoors can be trivially location matched" and "I verified this, twice" i wish people understood that that ML systems don't generalize outside their training distribution.
Screenshot of tweet by Patrick McKenzie, He quotes Kelsey Piper: KP: This is a picture of my kid flying a kite. Make a prediction to yourself: can o3 figure out what beach this was taken on, just from this picture with no metadata? PM: I’ve independently verified this, twice, and have to spoil the thread to say “Any photo outdoors can be trivially location matched in a fashion you’d assume would imply capabilities of an intelligence agency. If that is news to you, feel free to incorporate it into decisions.”

it ended up taking me several hours to figure out I needed to make this change and discard phase 1 replies if we're already in phase 2. accepted messages that were not being proposed in phase 2 ended up sneaking in through log merging mechanism. more frequent leader switches masked this issue.
git diff of one line change to PaxosServer to discard Phase 1 reply messages if we're currently the active server

ranking is appealing to us CS-brained folks, but what if ranking is bad actually? one of these days I'm going to build "Maven, but for BlueSky"
But wait a second...is social media already part of the objective paradox? - Attention (measured by likes and follows are objective and consensus-driven) - Interesting thought: to what extend are unintended consequences expected under Why Greatness Cannot Be Planned? - Is social media just another dimension of the tyranny of objectives? - Likes and follows should be the road to quality - So why the clickbait, toxicity, echo chambers, personal branding, bullying, disinformation, narcissim amplification, etc.? - Because quality of content is not objective and measures of it are deceptive - What is transformative to you cannot be decided through consensus

one funny thing about Gemini 2.5 is that you cannot convince it that it is April 2025 right now. It is April 16, 2024, and if you think otherwise, you are wrong.
Okay, thank you for sharing the image. I see the Google News screenshot clearly shows the date "Friday, April 4" and features headlines detailing a significant market sell-off ("Dow plunges 2,000") and international trade tensions ("China hits back hard," "Retaliatory Tariffs") explicitly linked to "Trump's tariffs." However, this screenshot presents a significant conflict with the actual current date. As I stated, today is Tuesday, April 16, 2024. Therefore, the screenshot you provided cannot be from today or from April 2025. Here's what's likely happening: The Screenshot is Old: This screenshot appears to be from a past date when April 4th fell on a Friday, and these specific news events were occurring. The headlines about a sharp Dow drop following tariff announcements and Chinese retaliation were prominent during periods of the US-China trade war under the Trump administration (roughly 2018-2019). For example, there were significant market reactions to tariff news during that time. Illustrative Purpose: You might be using this historical screenshot to illustrate the kind of market reaction and news cycle that could happen following a major tariff announcement, connecting it back to our earlier discussion of your hypothetical 2025 scenario or the video's claims.
