Not too concerned yet about AI replacing network engineers.
Screenshot of copilot output: Your DNAT rules currently only match destination ports >= 40000 and >=49152. Since 41734 < 40000, those rules don't match, so the packets aren't rewritten to 192.168.10.144

I bought a CO2 sensor just to see how things are going around the home. Not very well, as it happens.

I don't even see the code. All I see is blonde, brunette, redhead
Cropped screenshot of the bottom of a VS Code session with the terminal tab selected. The user has run the command "top" and the terminal is showing the expected text layout of "top" except that some text encoding error has occurred and all of the letters and numbers in top's output have been replaced by what looks like mostly Chinese characters

People are putting markdown into RSS now? Sounds like a great idea
Screenshot of an update dialog for NetNewsWire showing the new features in 6.10. The top dot point has been highlighted and it says "Added support for Markdown in RSS via the source:markdown element. When present, the Markdown is rendered as HTML"

Hot Diggity Dog, a fun AR game by Mel Huang where you have to move your face around and bite hotdogs, on display at the Science Gallery in Melbourne. The nod to the Windows 3.1 theme is a nice touch.
A computer game on a screen with a big button in a Perspex case. It’s in a public display area with a projector mirroring the screen overhead. The screen has a mock Program Manager from Windows 3.1 with an icon to start the game. Everything is in red and yellow colours. In game photo where someone’s face and mouth is being tracked as they try to position it over a hotdog for biting

Daang this is a demo app Apple published for devs to try out on-device OCR. The actually-hard parts of this are maybe 10 lines of calls to their Vision API. It has a tendency to turn ł→t, ż→z, ą→a, ę→e, but y'know, still, dang. There are things I want to do with this.
Screenshot of an app running on an iPhone. Most of the screen is a previously captured photo of an open book, the first page of Mały Książę, a Polish translation of Antoine de Saint-Exupéry's "Little Prince". All of the text on the page has thin red rectangles around each line showing the bounding boxes where text has been recognised. Around the photo are some UI elements: "Retake Photo", "View Text", "Accurate", "Language Correction", and a language selection dropdown. The result of clicking "View Text" from the previous screen. Another screenshot from an iPhone. It has a hearing "Text extracted from the image", following by the Polish text that was detected in small writing. The formatting is haphazard but the text all there with pretty decent (possibly perfect this time?) accuracy, demonstrating that the OCR process succeeded.

Edit of https://xkcd.com/303/ (Compiling) The #1 programmer excuse for legitimately slacking off: "My conversation's compacting!" -- (voice from inside office) "Hey! Get back to work!" (programmers having a sword fight on office chairs) "Compacting!" (from office) "Oh. Carry on."

I ran some quick numbers on 11 years of blogging. You can take me at my word when I say the em dashes will continue regardless of recent events. #emdash
a bar chart titled "Em Dashes". The X axis has the years 2014 through to 2025 and the Y axis shows yearly em dash usage ranging from about 14 to 48.

It's been years but I still see the bar chart emoji and think "dang we're going to need some more commercial zones"
enlarged screenshot of the "bar chart" emoji, at least as envisioned by Microsoft

Horseshoe Falls in Mt Field National Park, yesterday #tasmania
Outdoor photo of Tasmanian bush featuring a small waterfall with one flow from the left and another on the right, joining in the middle to create a horseshoe shape. Water flows over mossy rocks and the scene is framed by green fern fronds.
