The sculpture "Fragmentados" from 2015 by Enrique Ortiz Matos. It hangs on a white wall and depicts a forearm waving a tattered Puerto Rican flag. The arm is made of aged, twisted copper and almost skeletal in appearance. The flagpole and a few rope-like tendrils are made of the same copper, while the flag itself is composed of many wavy shards of glass matching the colors of the standard flag.
Graph showing that the US market has been down almost the entire time since Trump took office (after adjusting for inflation and the dollar value). The adjusted value of the market rapidly declined from January, bottoming out at -25% in April. It's been slowly recovering, and was briefly positive for the last two weeks, before going slightly negative again on April 7th. The graph uses the VTSAX index to track the US market; the adjustments are made using NYICDX for the dollar and CPI-U for inflation.

I have a kind of long and convoluted story, [redacted], your [redacted] whistles got someone out of custody on Friday. Last Friday. It's a bit complicated, so I'll share next time we are together, but you should please let him know that having the logo on the whistles resulted in a connection between two people during an abduction, and an advocate was able to get custody after they were taken from [redacted] house when his team was doing some work.

Source code comment with the following text: Note that there appears to be no official documentation covering the existence of specific pseudo handle values. In practice it's clear that e.g. -1 is the current process, -2 is the current thread, etc. The largest negative value known to be an issue with DuplicateHandle in fuzzers is -12. Note that there is virtually no risk of a real handle value falling within this range and being misclassified as a pseudo handle.

Archer "do you want ants" meme, with the caption: Do you want stagflation? Because that's how you get stagflation.
A vibrant, retro-style landscape reminiscent of the 1980s synthwave aesthetic. It features a large, glowing yellow and orange sun setting or rising behind a series of dark purple, jagged mountains. In the foreground, a grid-like neon blue and pink surface stretches out, giving the impression of a digital or virtual space. Tall, stylized palm trees with dark green fronds stand on either side of the grid, silhouetted against the colorful sky. The sky itself is a gradient of bright pink and deep purple, dotted with small, scattered stars. The mountains in the background are flanked by wireframe-style hills or dunes, rendered in shades of teal and green, further enhancing the retro digital feel of the image. The overall impression is one of nostalgia, a futuristic yet vintage scene often associated with synthwave music and culture.
