After a short break, Noah and Vivian return with another episode of JPEG2000 and it is another episode on artificial intelligence. This episode of J2k is sponsored by Dirt, a daily(ish) newsletter about digital pop culture and entertainment. JPEG2000 is still brought to you by Context.app, the best way to keep up with what's happening in web3. Context is also behind mint.fun, a product that allows you to mint new NFT projects safely from one interface.Since their previous episode about AI (episode 2), the conversation around AI has exploded and gone viral. Dall-e mini memes proliferated everywhere utilizing Dall-E mini now known as Craiyon, a text prompt AI image generator. An artist utilizing AI won first place in an art context, and the New York Times wrote about it. With that has also come skepticism, criticism, and fear regarding AI. Noah recalls an episode of his previous podcast All Consuming, he co-hosted with Adam Lisagor where he tests and discusses an AI tool called Parlo. Noah discusses his consistent discomfort about AI. William Wiebe is an artist and researcher whose work deals with machine perception, and created a project called SMPLVERSE which utilizes a synthetic data set created by Microsoft to train face tracking algorithms to translate facial expressions into the VR experiences. When connecting your wallet, you are prompted to take an image of yourself which is matched to one of the images in the data set. Vivian's Smpl can be seen here. Noah's is here. Noah calls Vivian in the middle of recording because he thinks the episode is too dense and needs a break. They collect a piece from Maya Man's project Fake It Till You Make it. Vivian revisits unused audio from David Young, artist and guest in JPEG2000's first episode on AI. David shares his concerns about bias issues with machine learning. This leads to a conversation where Noah discusses his thoughts about the ethics of AI and references an article by waxy.org. Noah and Vivian have a back and forth on the subject. During the Rose and Thorn portion of the show, Noah complains about Adobe and Vivian complains about COVID. JPEG2000 is edited and engineered by Paul O'Mara. The JPEG2000 music is by piano extraordinaire Yuri Beats. Noah and Vivian love attention so give them a call and leave a message on the JPEG2000 hotline by calling 845-377-3484.

After a short summer break, Noah and Vivian return with a new episode of JPEG2000 discussing glitch art projects God Observer by Godmin and Myfi by Aimee Rubensteen AKA Cookie Tree and Dr. Josh Eisenberg AKA  Dr. Slurp. After discussing God Observer in Episode 5, Vivian and Noah have Godmin on this episode to discuss her work more in depth. The piece JPEG2000 collected is titled  ∧⨆∃⨏⊷⋭⋌∉≃⋀≰⨑⨗◯ #1000356 which is part of the God Observer collection, which is a part of the larger Heaven Computer art project. God Observer posits "if we could look into an telescope, what if we could observe God, and what would it look like?" The work is made via video glitching, where the video is turned into audio, and turned back into video through a process called data sonification. On the Heaven Computer website, there is a section called God Remixer, where your God Observer piece can be edited. The God Remixer was inspired by FITS Liberator, a software program for processing and editing astronomical science data to reproduce images of the universe. The conversation is interrupted by a call from Noah in the future on a walk, where he sees amanitas mushrooms, reminding him of a piece titled Amanitas & The Sublime by artist Madeline Cass. Noah and Vivian collect the work and hear from the artist, who creates the works by scanning objects and digitally collaging things Noah and Vivian pivot and discuss a project called Myfi Studio, who sent a piece to the JPEG2000 wallet. Myfi is a project that is comprised of 106 hours of glitch video art with combinatorially arranged music about mycelium network that has a message for you. The piece JPEG2000 received a piece titled Bumping Tock in the Woods. To explain mycelium communication networks, Vivian has friend Sam Shoemaker on to explain. Sam is an artist and mycologist, who utilizes mushrooms in his art practice. Myfi posits that there is conceptually similarity between the mycelium network and the ethereum blockchain network. Noah and Vivian complain about various things during the Rose and Thorn portion of the episode. Vivian's rose was recently meeting Noah for the first time while traveling to New York earlier this month. Noah gave Vivian $2 bills as a birthday present.

In this episode, Noah and Vivian answer questions they received on the JPEG2000 hotline voicemail. If you have questions or comments, you can always leave a message too at 845-377-3484. To kick off the episode, Noah and Vivian collect from a project called Dropicall, created by artist GOODNEWSFORBADGUYS through Mezannotte, a curated platform for NFT projects. The Dropicalls look like little phones, which is on theme for a show centered around phone call voicemails. The piece JPEG2000 collected looks like this. After collecting, Matt from Mezannotte left a voicemail on the hotline, quickly to talk about Dropicall and Mezannotte's upcoming project White Hearts. The first call Noah and Vivian respond to comes from Jonathan Mann, the song a day man and Digitally Rare podcast host, who calls to share his thoughts about how language that begins in cryptocurrency influences the language of NFT art. This leads to a random conversation about visiting the US Mint and $2 bills. Kristen Cabrera , Web Developer extraordinaire at Foundation calls in to ask about why it is common to deploy contracts from burner wallets. Noah and Vivian do not know they answer, and have Malone, developer at Context.app, explain the answer. This leads to a conversation about chickens for some reason. The conversation is interrupted by a call from JPEG2000 podcast editor, Paul O'Mara, with a question about how to mint nfts. Vivian goes to Paul's house to help him. They discuss many things, including what is a smart contract. Sam Mason de Caires, previously at Foundation but now at Rainbow, to explain smart contracts. Paul creates his own smart contract, and mints a photograph titled Nitehawks, which Noah and Vivian problematically collect. When Vivian returns back to recording the episode, Noah has aged from the amount of time Vivian was gone. Photographer Aleck Venegas calls in from the streets of Manhattan to ask a question about NFT editions and re-editioning. Noah and Vivian talk again about Sam King's project ICE64. Writer Emily Sundberg calls in to ask about JPEG2000's vision for shopping in the metaverse, and what are ways brands can participate without being corny. Noah and Vivian do not really answer the question, but talk about Charmin toilet paper nfts. They also discuss David Rudnick's project Tombs, which Noah and Vivian both minted. A final question came in from photographer David Fitt on the Desire Path discord server, about if it's possible to mint NFTs from your phone. Vivian was able to deploy a smart contract on Foundation from her phone. She later minted nfts from her phone onto the smart contract, called PHONE.  Noah forgot Vivian's birthday :(

In this episode, Noah and Vivian discuss their thoughts and feelings about web3 lingo. GM. WAGMI. Diamond Hands. Rekt. So many words, so little time, so many feelings. Noah and Vivian receive a voicemail from their friend Sam, inquiring about what to do about a web3 wedding he has been hired to produce. Vivian suggests the guests should be dressed in DressX. As always....you can call and leave us a message on our hotline at: 845-377-3484. Vivian comes across a project called GM On Chain while browsing Context.app (thank you to our sponsors!). Unfortunately the project sold out, so Noah and Vivian had to collect a piece on secondary. The piece collected can be found on JPEG2000's context page.  Noah recalls work from photographer Aaron Ferguson, who had a collection of photographs of GM spray painted around his city. Aaron discusses his thoughts behind the photographs, his general feelings about web3 lingo, toxic positivity, NFT community, and favorite web3 term. A few more voicemails come into the hotline, with the callers discussing terms they do not like, including GM, GN, Ser, and LFG. This leads to a rapid fire discussion with Noah asking Vivian her thoughts on many popular terms in the web3 space. This leads to a larger discussion around words (lol???)During Rose and Thorn portion of the episode, Noah says his rose is a birthday present from Vivian. The present was a book titled One Star and a Dark Voyage by photographer Barbara Bosworth, who also happens to make NFTs. Noah and Vivian impulsively purchase a piece titled One Star #24, an image that appears in the book Noah received for his birthday. JPEG2000 is sponsored by Context.app, the best way to keep up with what's happening in web3, as well as for spying on wallets.

Somebody confesses their love for Noah, another person asks if NFT shill culture is the new New York Subway guy selling his mix tape, and a nice caller who likes Paul's editing. Do you have things you want to ask or talk about? Call the hotline at 845-377-3484. During Collection Time™, Noah and Vivian collect a Simpsons™ inspired piece titled "Sideshow" that is an edition of 15 from Connecticut based artist Chris Piascik, who is inspired by pop culture and punk rock music. Noah off handedly mentions that his Everyday video was spoofed by The Simpsons™. Vivian is jealous :( Chris Piascik discusses his thoughts around editions. You won't learn about it by reading the episode notes, and will instead have to listen to the episode. The episode is interrupted by Louis The Roofer, because Noah is getting his roof re-done, a process which Noah says is "a nightmare". Iain Nash, an engineer at Zora who works on API and platform engineering projects (including Zora's edition NFT tool) to discuss NFT editions from a technical perspective. Noah's chickens tell him to stfu. The episode is interrupted again by Vivian, who calls to play a voicemail left by photographer Sam King (a friend Noah and Vivian know via their Discord community called Desire Path). Sam calls to discuss his new photo project ICE64, a project which has original full res photos, but each photo also has an edition of 64 photos that are tiny 64x64 pixel versions of the original photos. These tiny photos are stored and rendered on chain, and will live on for as long as the ethereum network exists. This leads to a discussion about digital permanence and also the right to wipe yourself off the internet/curate your online identity by scrubbing your internet history. Previously in art history, photographers might burn their negatives and printmakers would score their printmaking surfaces to assure that the editions were truly limited. This leads to a discussion about artist proofs.In this episode's Rose and Thorn section, Noah and Vivian add a "bud" as suggested by Episode 5 artist Zak Krevitt, Vivian says her bud is that the podcast was featured by Spotify in their Business and Technology section. hint hint apple podcasts. Noah's bud is that his podcast with Paul (JPEG2000 editor extraordinaire) called Do You Hear That is in production. Noah's project Chicken Photos has gone live. Noah set up a camera which is trigged by his chickens. The photos are automatically tweeted to the @chickens twitter account, with select photos becoming available as NFTs.

Well it's ackchyually the name of a type of file format, which takes a big picture and filters it into a smaller picture. This man named Bruce explains it on Youtube. Wow, what a nice name for a podcast :) JPEG2000 now has a hotline where you can call in and leave a message. What are you thinking about? Do you have any questions about NFTs? What did you make for lunch today? Anything goes. Call now at 845-377-3484. Noah and Vivian listen to a message from one of the first callers to the JPEG2000 Hotline. Noah and Vivian collect a piece by Godmin (incorrectly referred to as Heaven Computer in this episode, which is the name of another one of the artist's projects) from her new project called God Observer. Using the JPEG2000 wallet, Noah and Vivian mint a piece titled ∧⨆∃⨏⊷⋭⋌∉≃⋀≰⨑⨗◯ #1000356. The episode is interrupted by a notification from BeReal, an app that Vivian forced Noah to download. As usual, the conversation turns once again to photography, and it's place within the NFT world. Noah and Vivian collect Shredder #012 from artist Zak Krevitt's project titled Shredders. Shredders is a generative photographic project, in which Zak explores new ways of thinking about photography as well as gender. Speaking of photography...Noah is working on a new NFT project utilizing a motion sensor camera and his chickens. You can keep up with the project on twitter @chickens. Noah says "it's a wild story" how he was able to secure that twitter handle. Do not inquire with him about how because it will certainly be a dull story. JPEG2000 is hosted by Vivian Fu and Noah Kalina.

In this episode Noah and Vivian discuss PFP projects (PFP stands for Profile Picture). What are PFP projects? Is this what everybody thinks about when they think about NFTs? Is this art? Why do people buy PFPs? What does it all mean? Maybe we answer some of these questions. Noah and Vivian describe their own current PFPs. Vivian's pfp is called Sprout Ride from the project Blitmap. Noah's pfp is a self portrait photobooth strip from artist Noah Kalina (wow!) Noah, Vivian, and the JPEG2000 wallet all collect pieces from artist Robert Gallardo's No PFP Project, a collection of 1,000 hand made PFPs referencing the default profile picture users have when using Instagram. Robert discusses his motivations and inspirations for this project, including One Year Performance 1980–1981 (Time Clock Piece) by Taiwanese artist Tehching Hseih. Coincidentally, Noah's own Everyday project is also inspired by the Time Clock Piece. Collector DeeZe shares his thoughts on PFP projects, discussing CryptoPunks, one of the first PFP projects he collected. Other PFP projects have since created "honorary" pieces for him, many of which make references to his CryptoPunk #465, which has a hoodie, 3D glasses, and a pipe. Why do people use the word "vibe"? What does it mean? Vivian makes vague reference to a newsletter piece she read about words. That piece is titled "Disregard the Words" by Josh Miller. Vivian and artist Maya Man met when they were both in an art show at the space Heavy Manners. Much of Maya's work explores online identity, and she offers some of her thoughts and theories about how people represent themselves online and what it might mean. Some parting advice: If people are being rude to you, they are likely just jealousssss

LensWork - Photography and the Creative Process

There is no question that JPEG2000 is better than JPG, but I'll take the universality of JPG every time. Pages is a convenient Mac word processor, but I'll use Microsoft Word or even better the RTF format for sending my documents every time for its universality. And for digital publishing of photographic projects, again I'll use PDF every time rather than some other, better delivery format for the simple reason that PDFs are universally accessible.

Today's episode  will be about deep learning and compression of data, and in particular compressing images. We all know how important compressing data is, reducing the size of digital objects without affecting the quality. As a very general rule, the more one compresses an image the lower the quality, due to a number of factors like bitrate, quantization error, etcetera. I am glad to be here with Tong Chen,  researcher at the School of electronic Science and Engineering of Nanjing University, China. Tong developed a deep learning based compression algorithm for images, that seems to improve over state of the art approaches like BPG, JPEG2000 and JPEG.   Reference Deep Image Compression via End-to-End Learning - Haojie Liu, Tong Chen, Qiu Shen, Tao Yue, and Zhan Ma School of Electronic Science and Engineering, Nanjing University, Jiangsu, China
