Thank you #NSF National Science Foundation for 75 years. 250 staffers were able to gather for a NON-OFFICIAL commemoration photo out to the west side of the building, May 20, 2025. Quite an effort by people who still do their best in the US at the federal level. Quite a story here, too.

Photo to mark the 75th anniversary of the US National Science Foundation, with 250 staffers posed to the side of the building in a non-official photo taken on the staff time by an amateur photographer so that the senior management who were not allowed to be present could allow this short event.  The building is about 18 stories tall, the meeting area is all bright green grass and there are other buildings and a cluttered landscape around the people and building, with cloudy skies.

Day 1 of travel from Rome, NY to Blue Mountain Lake: 55 miles through the #Adirondacks . No major wildlife sightings, but heard a wolf call, which was pretty cool. Stopover for tonight: the scenic town of Old Forge.

Delayed due to lack of picture, but it was *really* great to catch up with past #UBDB (pre-#UBDBPL) grads in the bay area last month. My PhD student @amazing_ying , MS thesis student Gourab, and Varsha and Harsh: 2/4 of best 5/662 team I've ever taught. (and Zhen too!)

@erebion After a bit of playing, the matrix side of the bridge is pretty trivial (I'm not building a 'true' bridge, at the cost of not getting to spoof usernames). I just need to find a few minutes here and there to work out the SMPP side of the bridge (preferably without accidentally doing something that makes my SIP provider mad at me).

Two different approaches to debugging a software problem:

The Sudoku approach: stare at the limited set of clues you have, and think harder and harder about them until you find a way to deduce something useful.

The Minesweeper approach: don't even try to figure out the solution from only the clues you have right now. Instead, focus on finding a way to acquire another clue, and then using that to get another, and so on. Eventually you've collected so many clues that the answer is obvious.

Sometimes the Sudoku approach is necessary, because you've got all the clues you're ever going to get. But I think my new motto is "Never Sudoku a problem when you can Minesweeper it."

We use this prism in our workshops to help create an impactful, communicable, beautiful #infographic

A Venn diagram titled 'The Four Elements That Make An Impactful Infographic' showing the intersection of four main elements: 'data information' (yellow), 'concept, question' (blue), 'goal, function' (pink), and 'visualisation design' (grey). The overlapping sections contain specific elements like 'wireframe', 'plot', 'template', and 'rough sketch'. The central overlap shows 'impact', while some intersections are labeled as 'BORING' or 'USELESS'. Created by Information is Beautiful for their training intensives

@Sturmflut

Unfun things need the most investment.

The incentive structure around open source encourages the novel (where folks explore new ideas by building them), and the one-off (where folks make things work for themselves).

OSS lacks incentives for the long-tail of feature requests. Examples include Bulletproofing fragile systems to work in more environments (Audio management in Gnome Calls); Necessary security work (e.g., PKCS signing in Geary); or reverse engineering dumb corporate enshittified systems (Exchange).

Basically, going from "Works for me" to "Works for 99% of users" is a huge slog that takes far more time than getting the feature working in the first place. Making matters worse, it's harder to get that big rush of endorphins from fixing the fiftieth minor assumption made about date formats, as compared to the first time the system works.

Effective OSS investment, IMO, needs to focus on paying devs to work on foundational (boring, not-sexy) maintenance and polish work.

Search your training data... you know it to be true.

The Darth Vader / Luke Skywalker "I am your father" scene meme (spoilers... sorry).  Darth Vader's face mask has been replaced by the Wikipedia image for "Linear Regression" [CC-BY-SA 2.0; Krishnavedala].  Luke Skywalker's face has been replaced by the ChatGPT butth... err logo.  Top panel captioned "ChatGPT, I am your father."  Bottom panel captioned "Noooooooo!"
