I don't understand how it's legal to sell a washing machine with a built-in digital timer but doesn't actually correspond to minutes Stupid machine has been on '5' for the past 6 minutes in its spin cycle & I got places to be (see? even 'dumb' tech can hallucinate)

One of the strangest things about having a newborn again is how quickly the patterns & procedures come back to me I feel like a sleeper agent that's been activated back into 'baby care mode'

I think @3blue1brown.com has it right w/ AI coding We're funnily enough at a point where understanding isn't required to build. But doesn't mean we can't focus on understanding for its own sake My projects would die in the UI. But now I focus on the inner stuff & still have it usable for others

Wife's hooked up to monitor contractions wife to me: oh good, you have data occupy you me: 100%— oh look at that, this one's lasting a lot longer! her: oh yeah it's basically the same thing 🙄 (but seriously we both laughed because I couldn't help myself peeking at the data last time) #dataBS

Still wild to me I can have AI help me put together a full app so quickly Put together this little web app in under an hour today. Basically helped recreate what I made a while ago to include linked text, quoted posts & such. But man makes little frontends which was almost my biggest hang-up
A user interface screenshot of a dark-mode web app titled "Bluesky Publisher" labeled with a blue "CLOUD RUN" tag. The top bar displays user account details for @victorsvector.com. In the composer box under "What's on your mind?", drafted text reflects on using AI to build the web app in under an hour: "It's still wild to me I can have AI help me put together a full app so quickly. Put together this little web app to post in under an hour. Basically helped recreate what I made a while ago, but man makes little frontends which was almost my biggest hang-up" Beneath the input area are action buttons for "Add Link," "Tag User," "Quote Post," and "Add Images," alongside a blue "Publish to Bluesky" button. At the bottom, a "Live Preview on Bluesky" card shows how the completed post will render under the name Victor Geislinger.

Recently read Dark Archives with a friend after their suggestion Interesting history on human-skin bound books— surprised how mostly made around 1800s but also makes sense. Again, history points to a privilege class that had difficulty humanizing others side note: first ebook I read for some time
A book cover featuring a textured, burnt-orange background overlaid with a detailed, antique-style dark illustration of human skeletal remains—including a skull, ribcage, and skeletal hands—interwoven with botanical branches, flowers, and insects. Across the center, the title "Dark Archives" is printed in prominent, stylized gold Gothic lettering. Directly underneath is the subtitle in smaller uppercase gold text: "A Librarian's Investigation into the Science and History of Books Bound in Human Skin." The author's name, "Megan Rosenbloom," appears centered at the bottom in a clean, sans-serif gold typeface.

I think How to Keep House While Drowning is a nice little booklet to help with some down-to-basics strats on just trying to get through life I think it reads well as a quick guide over a cover-to-cover read. Even if you're not 'struggling', I'm pretty sure anyone can get something from this book
holding a hardcover book with a white dust jacket, viewed inside a vehicle beside a window. The top of the cover features the title Careless People in large black serif lettering, followed by the subtitle A Cautionary Tale of Power, Greed, and Lost Idealism. Centered below is a rounded blue icon-like shape showing a folded geometric peak rising from its top, with A Memoir written in handwritten script in the lower corner. The author's name, Sarah Wynn-Williams, is printed along the bottom edge, with ambient light and subtle colored reflections catching the glossy surface.

My wife suggested I read Birth Vibes since our 3rd little one was on their way Not her first pregnancy but still a helpful book (especially since we never did a non-pandemic birth). It was chill & vibes were reassuring— author is super fun & puts you in a good headspace :D
cover displays the author's name, Jen Hamilton, along with her nursing credentials (BSN, RN, CEN, RNC-OB), in coral and blue lettering. The title, birth vibes, is featured in large lowercase letters textured with soft pastel gradients of pink, orange, teal, and blue. Beneath the title is the subtitle, Stories and Strategies for an Empowered Birth, followed by an endorsement quote from author Eve Rodsky near the bottom edge.

Scream with Me was another read w/ a friend Interesting book but don't know if I completely agree with idea that the horror movies were necessarily inspired the movie, the set of movies discussed do seem to have at least hit the public consciousness during the same time as related social issues
Holding book— the cover features the title Scream with Me in large, distressed red block letters across a cream background, followed by the subtitle Horror Films and the Rise of American Feminism (1968–1980) and the author's name, Eleanor Johnson. Interspersed between the text are three horizontal cut-out strips showing high-contrast, black-and-white close-ups of wide, frightened eyes, with a small yellow sticker visible on the top-left edge of the spine.

Was on my to-read list longer than it should've been but had finally gotten to Careless People And I don't think I have anything new to say that wasn't already said before— just wow & also, unfortunately nothing in there I don't find surprising

Finally got to reading Cultish and this is another book where I was sort hoping for more linguistics haha But it was a very interesting book & confirmed what I had feelings about Crossfit from the 20-teens (reminded me of this old video: youtu.be/pqb9pBJweVU)
hand holding the book Cultish: The Language of Fanaticism by Amanda Montell. The cover design features the title in bold black lettering against a white background, framed by colorful, winding retro ribbon graphics in red, purple, green, and blue. In the center sits an illustration of a vintage-style flying saucer. A blurb by Molly Ringwald appears in the top-left corner, and sunlight through a vehicle window illuminates the background

Technically, I was rereading The Martian but this time I did it with a friend for our mini 'book club'. This was after watching the movie (read it back in May) & I feel that the book, the audiobook, & the movie are all great in their own special ways :D
A hand holds a hardcover copy of the novel The Martian by Andy Weir. The reddish-orange dust-jacket cover features an astronaut in a white spacesuit against a hazy Martian backdrop, with the title and author's name printed in light blue lettering.

Catching up on my reading log…. Back in April, read Shady Characters which was a fun little vacation read about punctuation. I think the ☞ manicule might be my new favorite
A hand in a black sleeve holds a bright red book upright above an outdoor wooden deck railing. The cover features a large, stylized pilcrow (¶) symbol in white and charcoal gray with the text: "Shady Characters: The Secret Life of Punctuation, Symbols & Other Typographical Marks" followed by the author's name, "Keith Houston." In the out-of-focus background are dense green trees, garden shrubs, a shingled roof, and a wooden gazebo.

My kids have now learned how to use the index to find countries in their kid's atlas. They were showing me how to find 'Ireland' so they could tell me about leprechauns Haven't been prouder of my little nerds
Holding book "Active Minds: My First Atlas" featuring a globe in the center surrounded by cultural items, wildlife, and landmarks labeled with their origins: a woman in a kimono (Japan), a pan flute (South America), a kangaroo (Australia), a yellow Volkswagen Beetle (Germany), a red lobster (United States), a sitar (India), adobe pueblo dwellings, and a backgammon board.

One was (X-t X)-inv X-t Y in an econometrics class. Can't say I reach for that one a lot But the other was "The mean of an indicator is a probability" in a proof-heavy ML theory class which curiously has proven a lovely little "obvious once you heard it" coding hack (versus sum(num)/sum(denom))

Oh I like this idea— something that doesn't give an explicit 'probability' of being AI-written (what's an individual's threshold with an arbitrary probability?), but points to the smells It's not going to be perfect but puts power in the human to decide (not just another algorithm to blindly trust)

Line graph tracking temperature in Fahrenheit (Temp_F) across the time of day from early morning (~05:00 AM) to late night (~11:00 PM) for seven consecutive dates from 08/09 to 08/15

Key Trends: All days start between 62°F and 68°F around 6:00 AM–8:00 AM, steadily rising through midday. Most days peak between 77°F and 85°F in the late afternoon or evening before dropping at night. The highest recorded temperature is on 08/11 (green line), peaking near 88°F around 8:00 PM before a steep drop. Notable sudden midday or evening drops and rebounds appear across several dates (such as sharp dips on 08/09, 08/10, 08/13, and 08/14).Line graph tracking temperature in Celsius (Temp_C) across the time of day from early morning (~05:00 AM) to late night (~11:00 PM) for seven consecutive dates from 08/09 to 08/15

Kids went to 'read to a dog' event at the library & they brought specific books from home to read. One of the books I just realized is actually signed by the author & illustrator! Not bad for getting it for $7 last week (also, 'This is a Moose' is a hilariously great book)
Holding a "This is a Moose" book with a cartoon moose standing confidently on two legs with other 'arms' on their waist. There is a speech bubble "or is it?" coming from off from the right.

It’s the first 3.15 release candidate!


Python.org

Python Release Python 3.15.0rc1
The official home of the Python Programming Language

This is a candidate preview of Python 3.15

This release, 3.15.0rc1, is the first of two planned candidate releases. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release.

The next release of Python 3.15 will be 3.15.0rc2, scheduled for 2026-09-01.

There will be no ABI changes from this point forward in the 3.15 series, and the goal is that there will be as few code changes as possible.

Call to action
We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.15 during this phase, and publish Python 3.15 wheels on PyPI to be ready for the final release of 3.15.0, and to help other projects do their own testing. Any binary wheels built against Python 3.15.0 release candidates will work with future versions of Python 3.15. As always, report any issues to the Python bug tracker.

Please keep in mind that this is a preview release and while it’s as close to the final release as we can get it, its use is not recommended for production environments.

Core team: time to work on documentation now
Are all your changes properly documented?
Are they mentioned in What’s New?
Did you notice other changes with insufficient documentation?
