Yesterday saw the online premier of a mini-episode of a new animated comic series based on the classic Gilbert Shelton underground comic, the Fabulous Furry Freak Brothers. As a hippie wannabe teen in the 70s, this (and Zap! Comics) was everything to me.

In 1969, life in San Francisco consists of free love, communal living, and political protest. Freewheelin’ Franklin Freek (Harrelson), Fat Freddy Freekowtski (Goodman), Phineas T. Phreakers (Davidson) and their mischievous, foul-mouthed cat, Kitty (Haddish) spend their days dodging many things —- the draft, the narcs, and steady employment -– all while searching for an altered state of bliss.

But after partaking of a genetically-mutated strain of marijuana, the Freaks wake up 50 years later to discover a much different society. Quickly feeling like fish out of water in a high-tech world of fourth-wave feminism, extreme gentrification and intense political correctness, the Freaks learn how to navigate life in 2020 -— where, surprisingly, their precious cannabis is now legal.

OK, sounds good. But is it? If the reaction to the first mini-episode is any indication, maybe the Freaks should have remained in their drug-induced coma. As one Facbooker commented: "Get yourself a collected set of the original comic and skip this drivel!"

A couple of days ago, Thomas Dolby posted this video to Twitter and YouTube of a track called "Corona and the Pirate Twins," a spoof of his 1982 hit, "Europa and the Pirate Twins." The song is credited to Dolby Kids. Thomas included the following note:

"This is what my mischievous offspring have been getting up to during the Lockdown."

Here is the original video for "Europa..."

Bonus track:

And here is Thomas Dolby doing a touching home solo version of his achingly beautiful "Screen Kiss" from 1984's Flat Earth. He did it as a tribute to Matthew Seligman, the celebrated bassist who recently died of COVID-19. Seligman played bass on Dolby's recordings, including Flat Earth, and also played for Bowie, Robyn Hitchcock, Peter Murphy, and countless others. He was also a member of the Soft Boys.

It took hundreds of exposures and a complex method of removing occlusions, but this "lucky" shot is the result: a depiction of the hot regions lurking under Jupiter's uppermost clouds.

The picture was captured in infared by the Gemini North Telescope in Hawaii, and is one of the sharpest observations of the planet ever made from the ground. To achieve the resolution, scientists used a technique called "lucky imaging" which scrubs out the blurring effect of looking through Earth's turbulent atmosphere. This method involves acquiring multiple exposures of the target and only keeping those segments of an image where that turbulence is at a minimum.

Ironic toxic masculinity is in fashion! The Duke Cannon Naval Supremacy Big Brick of Bar Soap for Men [Amazon] promises that those thusly-soaped will smell of "naval supremacy", "productivity" or other humorously-abstract scents. (More traditionally "manly" odors such as tobacco, leather, burned vegetation, etc. are also available).

The veil of humor is threadbare -- "get clean and smell good without using feminine shower gels and accessories" -- but I'll admit that I do bathe in warm turpentine and it really helps.

This Sunday, Weezer will cameo on The Simpsons and as a teaser, the band released their cover of "The Simpsons Theme" by Danny Elfman. From Rolling Stone:

In the new episode of The Simpsons, Weezer will play a cover band called Sailor’s Delight, which serves as the house act on a romantic cruise Homer and Marge are taking. Sailor’s Delight will “perform” a handful of tracks from Weezer’s 2019 self-titled record (also known as The Black Album) and their 2017 effort Pacific Daydream, while the episode will also boast the premiere of the band’s new song, “Blue Dream,” from their upcoming LP, Van Weezer.

An array of scientific evidence suggest that in some cases, the bacteria in your gut–your microbiome–could be tied to neurological and psychological disorders and differences, from anxiety and autism to Parkinson's and schizophrenia. The journal Science published a survey of the field and the Cambridge, Massachusetts start-up Holobiome that hopes to use insight into this "psychobiome" to develop treatments for depression, insomnia, and other conditions with a neurological side to them. From Science:

For example, many people with irritable bowel syndrome are also depressed, people on the autism spectrum tend to have digestive problems, and people with Parkinson’s are prone to constipation.

Researchers have also noticed an increase in depression in people taking antibiotics—but not antiviral or antifungal medications that leave gut bacteria unharmed. Last year, Jeroen Raes, a microbiologist at the Catholic University of Leuven, and colleagues analyzed the health records of two groups—one Belgian, one Dutch—of more then 1000 people participating in surveys of their types of gut bacteria. People with depression had deficits of the same two bacterial species, the authors reported in April 2019 in Nature Microbiology.

Researchers see ways in which gut microbes could influence the brain. Some may secrete messenger molecules that travel though the blood to the brain. Other bacteria may stimulate the vagus nerve, which runs from the base of the brain to the organs in the abdomen. Bacterial molecules might relay signals to the vagus through recently discovered “neuropod” cells that sit in the lining of the gut, sensing its biochemical milieu, including microbial compounds.

A massive boom heard Wednesday night over Puget Sound on the northwestern coast of Washington was most likely an exploding meteor. Or that's what They want us to believe anyway. The American Meteor Society registered a dozen reports. Video above. Keep your eyes on the upper left of the frame.

"The more I read the more inclined I am to believe this was a fireball (which is a meteor that is larger and brighter than normal)," the American Meteor Society's Bob Lunsford said. "I'm certain now that this was a meteoric event."

From KOMONews:

Most meteors' explosions are heard about a minute or two after they explode due to the time it takes the sound to reach the Earth's surface, Lunsford said. Sound travels at 767 mph in standard atmosphere conditions, indicating this fireball exploded some 35 miles away.

"If this was larger than normal then the sound could have originated from a higher altitude. So a delay of 3 minutes is entirely possible," Lunsford said. "Meteors become visible at a height of around 50 miles so your estimate is well within that range."

Lunsford said because there was a boom, it’s very likely there are small, rock-sized pieces of the meteor somewhere on the ground. When a meteor causes a boom, it’s “pretty far down” in the atmosphere.

One positive upside of the past two months is how sheltering at home has all but emptied area animal shelters. It’s tough to get solid numbers nationally, but shelters in cities and regions all across America are reporting massive surges in animal adoptions. 

Even the steep increase in Google searches for “adopt a pet,” up a whopping 335 percent in April, proves what we probably all knew anyway — that in times of stress, having a furry friend is a huge comfort for millions.

Unfortunately, one of the downsides of the past two months is there are no trainers available to help whip some of these new family pets, particularly puppies, into shape. From barking and jumping to house training and scratching, The Complete Guide to Puppy and Dog Training Bundle is a full plan for getting the newest member of your family integrated into the house safely and sanely all by yourself.

The collection includes eight courses all geared toward getting a new dog or puppy behaving the right way. And if you’ve ever had any thoughts about starting a dog training business of your own, this coursework is a perfect starting spot.

Puppies: A-Z Guide to Puppy & Dog Training kicks off the learning, explaining the best way to train, teach and socialize your puppy so they grow into a joyful, well balanced, and well-behaved dog. 

Of course, most puppies each have their particular issues, so a handful of courses look more closely at some of the tactics for helping your puppy overcome certain challenging behaviors. Read the rest

Drummers hear all the jokes. What do you call a drummer with half a brain? Gifted. How is a drum solo like a sneeze? You know it's coming, but there's nothing you can do about it. What do you call a drummer that breaks up with his girlfriend? Homeless.

Drummers hear the jokes — and laugh. Because they know they’re the thumping heartbeat of any band. They’re the ones with loads of equipment. And they’re the ones making all that noise while practicing. Yet try to play almost any song without drums and the lack of propulsion and power is instantly palpable.

Drummers are essential. Now, users can join their ranks — and they don’t even need to buy a massive drum kit or rattle their walls to do it. Created by drummers, Senstroke by Redison is the first sensor device that can teach anyone to play the drums and even reproduce the drummer experience, all without any physical drum set.

Just attach the patented Senstroke sensors to a pair of drumsticks and your feet, connect via Bluetooth, and instantly you can turn any surface into a virtual drumhead. Using the impact of the drumsticks and your feet positioning, the sensors reproduce the exact sounds your chosen drum element would make through the Senstroke app. 

Your legs, some cushions, a coffee table, they all become fair game as a drum surface while you refine your skills. And when you attach a pair of headphones, no one else even has to know you’re playing...well, Read the rest

The "transient bazaar" known as Lost Horizon Night Market is a covert operation. Worlds are imagined and then built inside the blank canvasses of empty box trucks. For the event, all the "proprietors," and their appointed box trucks, convene in an unsanctioned, though discreet, location. This location is disclosed to would-be "shoppers" via text just a few hours before it starts. Word of the market generally spreads rapidly but not publicly, definitely not by social media. If you're lucky enough to hear about it, you should go.

So, Happy Mutants, this is your heads up. Lost Horizon Night Market: Quarantine Edition is happening Saturday, May 9, from 6:59p EST until 11:59p EST, "rain or shine." This one is a little different, as the spaces are virtual, not in actual, physical trucks. I got a sneak peek yesterday of what's been created and can't wait to dive in deeper. Admission is free, though tips are appreciated. RSVP here.

Game designer and publisher Dave Gilbert founded Wadjet Eye Games in 2006.  This interview features conversation about point and click adventure games; digital game development, marketing and publishing; and the relationship between art, passion and real world commerce.

Jeffery Klaehn: How did you first become interested in point and click adventure games?

Dave Gilbert: I played King’s Quest at a very impressionable age! I typed the word “jump” and I saw Graham actually jump, and I was so blown away that I’ve been playing them ever since.

JK: You founded Wadjet Eye Games in 2006 to sell your game, The Shivah, commercially, then moved to pursue game design on a full-time basis and released The Blackwell Legacy, the first in what would become a series of five games.  What are your thoughts on these games and on the market then compared to now?

Dave Gilbert: I am Blackwell Legacy’s biggest critic. It was the first game I wrote with the intention of selling commercially – The Shivah was originally freeware, so I don’t count it – and it shows every inch of my inexperience. The gameplay is clunky, the story is told in three giant infodumps, and the main characters weren’t very likable. But that said, I know with absolute certainty that it was the very best game I could have made with the experience, resources and time I had available. So I stand by it.

As for the market, everything is different. Back in 2006, indie games in general were a very new thing. Read the rest
