fitzwatermellow··on Ask HN: What lesser known startups are you excited about?
3D medical printing.

For example, BioBots.io has developed a "living tissue" 3D printer that uses photolithography versus mechanical or chemical deposition. It sells for $5K per machine. With recurring revenue of ~$1K for each cartridge of "bioink"!

R&D expenditures in the space are offset by partnerships with research institutions. And clinical demand is gargantuan. Two factors that could result in a $2B+ industry by 2022[1].

fitzwatermellow··on Machine Learning Unconference
Interesting discussion on the Gitter about livestreaming the unconference vs online participation vs freenode #ml channels vs tensorflow slack rooms vs /r/MachineLearning. But actually, it seems the Gitter for OpenAI itself is a great place to start! Maybe someone could volunteer to provide "live notes" of the Unconference on this channel?
fitzwatermellow··on How I wrote and published my novel using only open source tools
Ultimately, any text processing toolchain that uses ReGex for parsing will inherently be difficult to extend. And slow. And perhaps even broken. The disconnect lies in the human-machine readability gap. The only way to do it right, I believe, is custom text formats, scanned via structured strings into FSM grammers.
fitzwatermellow··on Ask HN: HN for China?
One source I've started reading daily is TechNode http://technode.com/. No community there, but a few interesting articles, in the hyped-up TechCrunch vein of startup journalism ;)
fitzwatermellow··on Ask HN: How have you increased your reading speed/comprehension?
I have a quick hack for reading long news articles on the web. Simply read the first sentence of each paragraph.

This works remarkably well. Most journalists seem to practice a uniform style when it comes to paragraph composition. The first sentence is the "thesis", and the subsequent ones provide the "evidence."

fitzwatermellow··on Ask HN: Why are techies so interested in Japanese culture?
The quintessentially Japanese focus on Mastery underpins the global obsession. Think about it! Or just watch The Last Samurai for the hundredth time ;)
fitzwatermellow··on Machine Learning Exercises in Python, Part 1
During the time of the original class, I don't think scikit-learn and spark were quite as mature. But perhaps Octave still enjoys a certain prominance in academic machine learning research. Matlab was also used for the recent EdX SynthBio class. And it just feels a bit archaic now, doing science in a gui on the desktop, instead of on a cloud server via cli ;)
fitzwatermellow··on YC Office Hours in 11 Countries This Fall
So much global demand. So difficult to scale. Might be time to consider a kind of YCx extension program, where independent local organizers, who are most keenly aware of their native flavor, can get the tools to self-organize their own startup community's office hours, seed funds, incubators, etc.
fitzwatermellow··on Algorithms that select which algorithm should play which game
Link to paper needs to be fixed.

Thanks togelius for the survey of the current state of the art around GVGAI! It will be interesting to see how adversarial methods influence future game design. Is a perfectly "instinctual" game possible? One that can never be beaten by any machine but that even a two-year old can master immediately?

"all the go commands operate on packages, the use of files is a degenerate case only to support go run"

guilty. typing in "go run" for quick scripts is one hard to conquer habit ;)

fitzwatermellow··on Most of us would be better off without lawns
I plan on saving this article. Then I will write an agent that will search the text for any phrase that contains the concept of "landscaping." It will then replace those selections with new phrase sentiments generated from a random list of similar acts of drudgery. Laundry, driving, bathing, child-rearing, grocery shopping, sight-seeing, reading, speaking, attending weddings, barmitvahs, dentistry, cosmology, climate change, signing autographs, game of thrones, breakfast, etc. I plan on calling it the Deep Whine program. I expect it to be the first AI with a regular column in the Op-Ed section of a major national news publication.

fitzwatermellow··on A Swede Returns to Silicon Valley from China
What's the point of innovation if you're not building a better society?

It may be that the inherent American modes of self-reliance, personal responsibility and individual liberty create natural frissons with innovators trying to implement the betterment of society via "liberation technologies."

Whereas Asia, with a deeper cultural affinity for familial duty over individual desire, and an inherent necessity to rapidly raise standards for the millions that still live in agrarian lands, would provide more fertile ground for "sharing economies."

In the near term, it may seem like all the excitement is occurring across the Pacific. But if we can recall the original mission of the PC Revolution: to empower and enhance our natural capabilities, that humans with machines are substantially better equipped at survival and the optimal pursuit of life than either alone can ever be. We may ultimately stumble into that New Jerusalem here in the West.

Where "Man is his own star; and the soul that can render an honest and a perfect man, commands all light, all influence, all fate!"

fitzwatermellow··on Show HN: A simple infinite world in WebGL
Thanks for posting. This brings back a lot of fond memories for me. The good old days when I was still teaching myself DirectX and OpenGL. Copying and updating ancient demoscene tutorials. These sorts of vector terrain flythroughs, infinite wormholes, looping roller coasters, dancing sinewave text animations and eternally zooming julia sets were my bread and better for understanding geometry and shading. The Moment of Zen here is, as you noted, how little actual code is required to build a world. Keep going ;)
fitzwatermellow··on Ask HN: What are the best resources for learning about gamification?
I can recommend the Gamification MOOC run by Prof. Kevin Werbach at Wharton:

You're in luck, next session starts August 15 ;)

fitzwatermellow··on Is it ever a good idea to perform self-surgery?
In her speech to the Democratic National Convention last night, Academy-Award winner Meryl Streep gave a shout out to Deborah Sampson who disguised herself as a man in order to serve in the Continental Army during the American Revolutionary War. Earning the title of: "the first woman ever to take a bullet for our country."

From wikipedia:

Sampson fought in several skirmishes. During her first battle, on July 3, 1782, outside Tarrytown, New York, she took two musket balls in her thigh and a cut on her forehead. She begged her fellow soldiers to let her die and not take her to the hospital, but they refused to abandon her. A soldier put her on his horse and took her to a hospital. The doctors treated her head wound, but she left the hospital before they could attend to the musket balls. Fearful that her true identity would be discovered, she removed one of the balls herself with a penknife and sewing needle, but her leg never fully healed because the other musket ball was too deep for her to reach. On April 1, 1783, she was promoted and spent seven months serving as a waiter to General John Paterson.

fitzwatermellow··on Popular Electronics archives
Thanks so much for posting! Doing a bit of research in post-war research and technology and source material such as this is the ultimate!

I personally love the adverts from the 1940-50s that beckon entrepreneurial spirits to enroll in a radio or tv technician correspondence course. The copy is so similar in tone to modern day "Learn iOS" adverts from Flatiron School and the like: seize your destiny, build the future, get paid to do what you love, while changing the world.

fitzwatermellow··on Study opens new realms of light-matter interaction
Link to research paper: "Shrinking light to allow forbidden transitions on the atomic scale"

http://science.sciencemag.org/content/353/6296/263

"...in principle it has potential to enable the full use of the periodic table for optical applications.” Wow. Any Physics grad students looking for a topic, I'd say "surface plasmons" are about to get quite a bit more exciting ;)

fitzwatermellow··on Asciinema 1.3 Switches from Go Back to Python
Often I encounter similar instances where something fundamental is missing from golang's standard packages and no third-party library exists.

Authors cite superior support for tty on variant archs. But by using golang as the central pipeline manager, calls to jsdom or PIL or ffmpeg simply become another stage in the pipeline. Any number of Python microservices can be composed, while retaining golang as the glue providing timeouts, sync, etc.

Still, whatever works for the Asciinema is OK in my book. Great service and will be recommending to all!

fitzwatermellow··on Asciinema 1.3 Switches from Go Back to Python
I actually discovered it from your post the other day, antirez. The CLI thingy. And I concur. It is a truly wonderful tool I will be using extensively: Docker inits, first N steps in spinning up an instance, setup devenv and build first "hello world," and much more ;)
fitzwatermellow··on Writing an editor in less than 1000 lines of code, just for fun
Wow! I love this!! Thanks for the post antirez, if just for introducing me to this now indispensable tool ;)

fitzwatermellow··on Mozilla Fathom: Find meaning in the web
HTMLElement.dataset is string-typed, so storing arbitrary intermediate data on nodes is clumsy

I use dataset extensively. Once each DOM element is assigned a unique key id, many things get simplified: DOM manipulation, client server state sync, event handling, etc. Now if an additional data layer can resolve key id to semantic metadata, the only problem left would be to expose that data so third parties can read from it. So, the problem could be solved with three data points: url, dom key and the resolved metadata value.

What's really needed isn't a new protocol or set of rules and conditions. OpenGraph probably works just fine. It's a dedicated global database of metadata. A web white pages directory. As OpenGraph is perhaps dominant, it may make sense for someone like Facebook to provide this. Historically, third party non-profit services have not been popular.

All of this is of course contingent on the assumption that content hosters provide that metadata to begin with ;)

fitzwatermellow··on Ask HN: Best place to learn GPU programing?
If you want to dive in deep right away, an interesting summer project would be to create hybrid client / server gpu clusters using webgl and the browser!

Install node-opencl and CL.js and check out how Graphistry is using scalable distributed gpus for visualization of massive data sets ;)

Just many thanks for the book! This is the one I keep under my pillow ;)
fitzwatermellow··on Twilio's Seed Pitch
Great story! And congrats to Twilio on the IPO, 90% first day of trading pop, and creating a great (and essential) service ;)
fitzwatermellow··on Ask HN: Are you using Go for web development?
You'll want to take a look at Sameer Ajmani's (Go Team Manager) talk "Program your next server in Go"

https://talks.golang.org/2016/applicative.slide#1

As well as this post on "Go Concurrency Patterns: Pipelines and cancellation"

https://blog.golang.org/pipelines

You'll get a feel for how you can use Go to quickly build and compose distributed microservices that can "time out" but still won't bring down the entire house of cards ;)

fitzwatermellow··on Can Google or Facebook ever have a true competitor?
The one company I believe may be on a path to a position of true "anti-obsolescence" is Amazon. I consider the way people younger than me use it for everything. Then I consider my own Prime usage which is up perhaps 100-200% over last year. And even after that I look at the future innovation's Amazon is planning: 1-Hr delivery via drone, dev friendly alexa tasks from anywhere. And I can't think of anyone that can currently be termed a "true" competitor. And I am clearly not the only one to notice. $AMZN stock up %50 since Feb ;)
fitzwatermellow··on Concrete AI Safety Problems
> Can we transform an RL agent's reward function > to avoid undesired effects on the environment?

To me this is the toughest nut in the lot. Training a Pac-man agent to avoid ghosts and eat pellets, in a world of infinite hazards and cautions! Any strategies?

fitzwatermellow··on OpenAI technical goals
Goal 5: Inventing the Next Paradigm

Any impetus into actually dreaming up what may come next after GPUs and Async DRL? Non-neural models, quantum computing based AI, optogenetic hacking ;)

Otherwise, excellent list!

fitzwatermellow··on Ask HN: What are your thoughts on the 2016 NBA Finals?
“I watched Beethoven tonight, I watched LeBron James compose a game.” -Kyrie Irving
fitzwatermellow··on Arthur Conan Doyle and The Strand
And for you Sherlockians who still just can't get enough, there is "I Hear of Sherlock Everywhere," the definitive Sherlock Holmes podcast and website at the intersection of news and popular culture:

http://www.ihearofsherlock.com/

I can also recommend the two novels by Anthony Horowitz, House of Silk and Moriarty. These are the only two contemporary works to earn the seal of approval from the Conan Doyle Estate. And Horowitz, creator of the beloved ITV British detective drama "Foyle's War", knows a thing or two about mystery and suspense ;)

But I don't think you can really discuss Conan Doyle without commenting on the influence of Edgar Allan Poe. And how even to this day in internet forms like creepypasta and #nosleep, Poe's innovations continue to, ahem, haunt us.
