In case people are curious what I'm working on, I'm noodling on a tool for helping develop and publish intent specifications which I'm calling Keystone
A screenshot of a web app. There's a ton of text so I apologize for not transcribing it all. The important parts are: 1) The app is called Keystone (with a nice logo of two architectural columns with an arch connecting them); 2) the current project is "TCAS Example"; 3) the left sidebar has a taxonomy of "Goals", "Losses", "Misbehaviors" etc., and then a list of Documents beneath it; 4) the current document (with its table of contents expanded in the sidebar) is "TCAS Intent Spec"; and 5) We are currently looking at a section called "Level 1: System Level Goals, Requirements, Constraints"; and 6) the text of a chapter called "Introduction" is displayed underneath. There are various add/edit/delete buttons also where appropriate.

Like what the fuck is this shit. This is a paid commercial product. The original PDF is perfectly readable to a human.
Screenshot of the original PDF showing perfectly readable text. I don't have alt text for it because, well, see parent post. Screenshot of complete garbage OCR'd text. All errors in the alt text are regrettably also present in the screenshot. "This sa+rip1e intent specification for THAT was produced by Nancy T eveson (T evels 1 and 2) and .hon Reese (T evels fi and 4). We have built on the RñMT specification produced by ourselves, Mats Heimdahl, and Holly Hildreth for the FAA, but we have changed the notation and modeling language and have expanded the spec- ification to include the entire MOPS Volume 1 and 2 (published by the Radio Technical Commission for Aeronautics) along with additional information. This specification is an example of an Intent Specification and should not be used to provide information about any real implementation of TCAS or any current version"

In doing this, Caesar laid the foundations for the political geography of modern Europe, as well as slaughtering up to a million people over the whole region. It would be wrong to imagine that the Gauls were peace-loving innocents brutally trampled by Caesar’s forces. One Greek visitor in the early first century BCE had been shocked to find enemy heads casually pinned up at the entrance to Gallic houses, though he conceded that, after a while, one got used to the sight; and Gallic mercenaries had done good business in Italy until the power of Rome had closed their market. Yet the mass killing of those who stood in Caesar’s way was more than even some Romans could take. Cato, driven partly no doubt by his enmity of Caesar and speaking from partisan as well as humanitarian motives, suggested that he should be handed over for trial to those tribes whose women and children he had put to death. Pliny the Elder, trying later to arrive at a headcount of Caesar’s victims, seems

Slack, I'm a single-channel guest, maybe don't go leaking total message volume to me? Especially above a link that doesn't work because I don't have permissions to view the page in question?
A screenshot of an email from Slack. (Not included in the screenshot, but the subject line of the message is "You've got 2 unread messages") Under the Slack logo, there's section bar indicating the (redacted) name of the specific Slack, "12 members", "(fire emoji) Your team has sent 139 messages recently," and a button to "View all unread messages". Below that, the heading "New messages in #(redacted channel name)"

Oof. Wages for the lowest earners are now *WORSE* off than they were *BEFORE* the pandemic. And a *LOT* of us are about to get hit with big health insurance premium spikes.
Graph from the NYT showing "Change in Wages from a year earlier" where "Highest earners," "Lower middle", and "upper middle are above where they were in 2020 but "Lowest earners", who actually saw the largest wage growth over the period 2015-2023, are now doing worse than the other cohorts again, and worse than they were in 2020.

“away. I checked my phone again before I got out of data range, discovered that it hadn't charged worth a damn and was also hot enough to fry an egg. "Sonofabitch..." I pulled over, did a quick search online, discovered that there was a known bug in the latest operating-system release that made the phone run hot and burn battery like it was going out of style. They promised to fix it really soon. Great. Well, it's not like I got signal out at Grandma's place anyhow. I switched off my nicely toasty paper-“

What’s your sign?
Two posters. First poster: “To start a fire you must have: (triangle containing flames with words written on the sides) Fuel, Oxygen, Ignition. No TWO alone will burn. Gases. Separated—safe. Incorrectly mixed—dangerous. Safety is a full time responsibility!” Second poster: “industrial accidents (like this one)”—illustration of what looks to me like an exploded gas regulator valve—“can cause… Injury, Lost time, liability, property damage, administrative headaches. Safety is a full time responsibility.”

Nobody would have any problem with the idea that the Gestapo should be dissolved and prosecuted. Application of this principle left as an exercise for the reader
Tweet from Brandon (bedubble.bsky.social): “Frankly, ICE being dissolved should become the most conservative position allowed in democratic politics.”

There's a statue depicting the Hans Christian Andersen version of the "Emperor's New Clothes" fable in the park in one of the towns I grew up in. However, the emperor being actually naked was determined to be shameful, so the emperor is depicted wearing clothing. I feel like this says a lot

I have been graphing a couple different "official" forecasts against my own data which has been a fun, and why I wound up going with OpenWeatherMap's more local forecast for my general use rather than the NWS's forecast for JFK airport
Graphs from a web dashboard. Titles are "Actual vs Forecast Temperature (Bedroom)" and "Actual vs Forecast Temperature (Front Room)". Legends are "Outside (Bedroom)", "KJFK temperature", and OpenWeathermap Temperature" on the first and "Outside (Front Room)", "KJFK temperature", and OpenWeathermap Temperature" on the second. Graphs show a river between highs and lows, for the last 30 days. In general, the observed highs are higher than either of the two forecasts' forecasted highs, and the observed lows are also higher than either of the two forecasts' forecasted lows.

There's currently a 5°F difference between the temperature sensors *at my house* (neither of which exactly agrees with an "official" OpenWeatherMap forecast)
Screenshot of a web dashboard. Cards read: "Outside (Bedroom): 83°F," "Outside (Front Room): 78°F," "Sunny (OpenWeatherMap): 76°F (76°F / 58°F"
