The European Space Agency (ESA) has successfully 3D printed the first metal part aboard the International Space Station. This achievement marks a significant advancement in in-orbit manufacturing that could enable the production of essential spare parts and tools for future long-duration space missions. "The first metal shape was produced in August, and three more are planned as part of the experiment," notes The Register. "All four will eventually be returned to Earth for analysis -- two to ESA's technical center, ESTEC, in the Netherlands, one to the agency's astronaut training center in Cologne, and the last sample to the Technical University of Denmark." From the report: During a panel discussion following the UK premiere of Fortitude, a film about the emerging commercial space industry, Advenit Makaya, Advanced Manufacturing Engineer at ESA, remarked on the potential for recycling space debris in the process rather than having to rely on raw materials launched to the ISS. Rob Postema, ESA Project Manager for Metal 3D, told The Register that the agency was indeed looking at "circular" solutions in its drive for greater sustainability. However, don't hold your breath for putting bits of space garbage into one end and getting shiny metal parts out of the other: "A timeline is difficult to indicate, some early results are achieved with ground activities, ready to evaluate solutions in space."

The printer is overseen from the ground and operated for around four hours per day. The ground team has to check each layer via images and a scan of the surface area; printing a sample can take 10-25 days. However, Postema said: "Through automated control of the printing process as well as continuous operations, this can be substantially reduced." Knick-knacks from orbits are all well and good, but could something more substantial be produced? Yes, although not with this demonstrator, which can print to the outer dimensions of a soft drink can. Postema noted that while the demonstrator could manage smaller parts, either as a single unit or as part of larger structures, "there are definitely opportunities to create 3D shapes and parts with this technology larger than what we have done with this Technology Demonstrator."

Longtime Slashdot reader tlhIngan writes: As reported in many outlets, Epic Games has acquired indie music store Bandcamp to build out a "creator marketplace." Bandcamp will continue to be run as it is. "The products and services you depend on aren't going anywhere," wrote Bandcamp co-founder and CEO Ethan Diamond in a statement. "We'll continue to build Bandcamp around our artists-first revenue model (where artists net an average of 82% of every sale), you'll still have the same control over how you offer your music, Bandcamp Fridays will continue as planned, and the Daily will keep highlighting the diverse, amazing music on the site."

Diamond says the company will be working with Epic in the background to expand internationally and "push development forward" across its services, "from basics like our album pages, mobile apps, merch tools, payment system, and search and discovery features, to newer initiatives like our vinyl pressing and live streaming services."

Bandcamp adds to the long list of companies under the Epic Games umbrella, notes Eurogamer. "Since 2018, Epic Games has, alongside ArtStation and Sketchfab, acquired the likes of Cloudgine, Quixel, SuperAwesome, Hyprsense, RAD Games Tools, Tonic Games Group -- which includes Fall Guys developer Mediatonic and Fortitude Games -- plus Rocket League studio Psyonix, and Rock Band developer Harmonix."

Back in November you had a chance to ask Rachel Sussman about photography and her work. Her most famous project may be the Oldest Living Things in the World, a collection of organisms that are 2,000 years old and older from around the world. Below you'll find her answers to your questions.

cgjherr writes "If the recent financial meltdown has left you wondering, 'When does exponential decay function stop?' then I have the book for you. Advanced Excel for Scientific Data Analysis is the kind of book that only comes along every twenty years. A tome so densely packed with scientific and mathematical formulas that it almost dares you to try and understand it all. A "For Dummies" book starts with a gentle introduction to the technology. This is more like a "for Mentats" book. It assumes that you know Excel very well. The first chapter alone will have you in awe as you see the author turn the lowly Excel into something that rivals Mathematica using VBA, brains, and a heaping helping of fortitude."

Michael J. Ross writes "Web 2.0 applications and sites commonly employ a number of technologies: PHP, MySQL, XHTML, CSS, JavaScript/Ajax, microformats (standard formats for HTML data), tags (keywords for categorizing site content), and Web feeds (formatted and streamed Web content, usually in XML, such as an RSS feed). Because learning and using most of these technologies can be rather challenging to a Web developer, perhaps the best way to get started doing so is by using all of them to create a single Web-based application, with no pretense at mastering any one of them. This is the approach taken in Quentin Zervaas's book, Practical Web 2.0 Applications with PHP." Read on for the rest of Michael's review.

Slashback tonight with another assortment of corrections, amplifications, looks backward (and even looks forward to looks backward). In this last case, it looks like you may even get fed.

Thanks to a rather interesting string of e-mails (Thanks Evan!), today's feature writer is none other than David Brin. Brin's bio is after his piece, but suffice it to say he's one of the most interesting writers, IMHO, out there today. This piece, one of his essay's, deals with why George Marshall should be Man of the Century. (Another one of Brin's essays that many of you will remember is his work dealing with Star Wars, Episode One.)

Well, I seriously doubt any of you were going to buy the latest endeavour from Mr. Gates, but I've got two simply scintillating reviews, courtesy of Jon Katz and Doc Technical (Of The Story of Ping fame. Which, BTW, I know ended up on Amazon. We had it first *grin*.) Click below for some excellent Monday morning reading.
