It’s the famous publicity photo with him facing sideways, looking to the camera and showing off his bicep with the Boss tattoo on it.

As I pivot from DragonCon to celebrating Star Trek Day, I just want to shout out all the amazing fans who have created a family out of a franchise. I’m deeply honored to be a part of this legacy, and grateful for every moment 💙🖖🏻💙 #StarTrekDay

DragonCon was delightful and healing, especially after losing Tim Curry. It reminded me of how many good people are still out there being their authentic selves and creating amazing art. Also our costumes were great!

I've had no less than a dozen friends and family, some I haven't spoken to in years, reach out to me in the last hour. This one hits really hard. He was my first love, my first...obsession...if you will. Sending love to all my fellow freaks and weirdos. Tim was a beacon for all of us. 💔

I did get my Hutton Orbital mug today! My Elite Dangerous videos are heading to my YouTube channel this week; stay tuned! Of course I swapped ships at a station in Wolf 359 (Yes I celebrated with my actual physical Hutton mug that my spouse got me the first time I did the run)

This is true, and why I’ve been working on transforming my tattoos, starting with the most prominent one. I hated the idea that someone could see it and think I was an unsafe person.

the least realistic thing about star trek is that starfleet uniforms don't have pockets and nobody complains about it
crisisoninfintefandoms replies: 
My instinct is to agree with this, but like, when I really think about it...
No money, no credit cards, identification is all vocal/fingerprints/retinal, so no wallet.
Again, doors are voice activated, or just unlocked by entering a code. No keys.
Communication devices are tiny and stick onto clothing starting in Next Gen.
TOS had bulkier communication that they carried around or kept in, like, packs and stuff, so the arguments for pockets is a little more valid, and if I remember correctly, those costumes did have pockets, tho I could be wrong about that. But anything post TNG, the point is moot anyway.
Tricorders and phasers are really the only thing anyone's carrying around, and that's usually on away missions where they'd be bring their packs/holsters or just have them out. I mean, who wants to stick a phaser in their pocket?
So, yeah. There's not much little stuff people need to carry around everywhere.
And if they are preparing for a longer journey or want to bring bulkier things. well... just bring a bag. It fits more anyway.
jimkerk replies: 
what if i find a cool rock and want to take it home with me
runicbinary replies: 
Every time a member of the USS Enterprise has found a cool rock and taken it home, it has resulted in eleven deaths, six temporal displacements, the holodecks breaking again, and somebody getting turned into a lizard. Pockets are a privilege, not a right.

This bit got me… (it’s all wild)
So, effectively immediately, we will no longer prohibit artists who use Al from taking part in our markets. (You folks who do fan art... that's still stealing, and is still not permitted.) In addition, while I'm not going to start generating my own Al images, I'm also not going to stress about Al being used for images I purchase for promotional purposes. It's too hard to avoid, and trying to do so wastes a lot of my time.
My first priority is to create a successful event that benefits the artists and artisans taking part, and I will continue to bust my ass to do that. My second priority is my own mental well-being.

This is such a sad story: She was the first pro woman astronomer in the UK, but after being passed over for promotion Annie Walker left astronomy and never talked to her family about her work. They are searching for a photograph of her to hang in Cambridge. www.theguardian.com/science/2025...
But Hurn thinks Walker probably never knew her contributions to astronomy had been recognised during her lifetime and her status as a pioneer was neglected by previous curators of the observatory's history. "She was the first professional woman to earn a living from astronomy," said Hurn. "But if you asked most astronomers today, they wouldn't know her name."

This is a clear attempt to silence dissent and criminalize those who speak out for justice.
ICE raids are tearing families apart and have demonstrated zero evidence in making us safer. This is a brutal campaign to target our most vulnerable, intimidate us, and dismantle our freedoms.

Donald J. Trump
@realDonald Trump
The Movie Industry in America is DYING a very fast death. Other Countries are offering all sorts of incentives to draw our filmmakers and studios away from the United States. Hollywood, and many other areas within the U.S.A., are being devastated. This is a concerted effort by other Nations and, therefore, a National Security threat. It is, in addition to everything else, messaging and propaganda! Therefore, I am authorizing the Department of Commerce, and the United States Trade Representative, to immediately begin the process of instituting a 100% Tariff on any and all Movies coming into our Country that are produced in Foreign Lands. WE WANT MOVIES MADE IN AMERICA, AGAIN!
