I have restarted work on the GE NEP crewed Mars mission post. After all the turmoil this past month, it's like meeting with an old friend.

My goal is to finish the post by Halloween.

Speaker Mike Johnson made baseless, inflammatory claims about the No Kings protest on October 18.

Maybe this is why.

There are 2465+ planned... and growing.

The power of the people is greater than the people in power.

Remember that there are righteous people among us, always.

Left: Netherlands, 1942

Right: Illinois, 2025

One day in the summer of 1942, after the onset of the deportations of the Jews from Holland to “the East”, a student, who was a courier for the ASG student underground group in Amsterdam, approached the de Vries family, asking them to hide a Jewish child. The de Vrieses, who had two children of their own, decided to accept the offer despite the risk that was involved in hiding Jews, and soon four year-old Louise Pinto was brought to their home.

Amid the smoke bombs and screams that ricocheted throughout a South Shore building last month during a massive military-style immigration raid, one man heard a knock on his door.

On the other side was a mom and her 7-year-old daughter, pleading for his help.

“I wasn’t planning on letting her stay, but I didn’t know what the hell was going on,” the man said of his Venezuelan migrant neighbors. But he quickly relented. The little girl was inconsolable and hid under his bed.

“I didn’t want them to take her,” said the man, who didn’t want to be named because he fears he’ll be targeted by federal authorities for his actions.

“I gave her my bedroom, and I just told her, ‘Just stay there. Don’t open, don’t, shh, just stay quiet,’” he recalled telling the mom and daughter as he choked back tears.

The image is split into two panels. The left panel shows a flock of sheep crammed into what appears to be a kitchen. The sheep are mostly white, with one black sheep visible. Some of the sheep have red markings on their wool. The right panel features a brown and white border collie dog sitting amongst some greenery with a sheep in the background in a field. The text above the images reads "Sheepdog puppy herds entire flock into owner's kitchen," followed by "Metro" and then "A prodigy." Below this, there is a comment by user "sindri42" that reads, "You missed the best part. They weren't even their sheep. This good pupper gathered up a bunch of random sheep it found somewhere on the countryside and brought them home for its human."

there’s this weird idea a lot of people seem to have about how all of us writers and artists must secretly want to use AI and are merely resisting temptation for ethical reasons, and like, no, it’s not hard for me to resist drinking the bowl of Piss With Glass In It actually
