fitzwatermellow··on Samsung Acquires Joyent
Nice win. SaaS M&A so hot right now ;)

We use Joyent for nodejs microservices, chiefly any server side DOM manipulations (using jsdom), and it's been solid! Currently evaluating docker container management and will give Triton a go...

fitzwatermellow··on CS188 Intro to AI – Course Materials
After finishing CS188, if you want to "go deeper", check out Berkeley's CS 294: Deep Reinforcement Learning, Fall 2015:

http://rll.berkeley.edu/deeprlcourse/

And you should be well on your way to being able to read and comprehend the Google DeepMind papers posted on Arxiv ;)

fitzwatermellow··on Show HN: I made a database of remote companies
It also forms the basis of a platform and trusted brand that can provide third party services bridging the gaps between remote hires and startups. Nicely done!

I am quite heartened as well to see a wall of companies functioning at "100% Distributed" ;)

fitzwatermellow··on Deep Reinforcement Learning Using Keras and OpenAI Gym
It's interesting that the unintended constraint of most folks running these environments on their home commodity laptops instead of a bank of Tesla GPUs may prove extremely beneficial!
fitzwatermellow··on 100 things that are broken, according to HN
This really calls for one of those "trend forecaster"-style four quadrant diagrams: broken / unbroken on one axis, fixable / unfixable on the other ;)
fitzwatermellow··on Motion Stills – Create Looping GIFs from Live Photos
Link to underlying CV research breakthrough:

Auto-Directed Video Stabilization with Robust L1 Optimal Camera Paths

http://www.cc.gatech.edu/cpl/projects/videostabilization/

Stunning amount of optimization required to make virtual cinematography possible in real-time on a mobile device!

fitzwatermellow··on Ask HN: Who is hiring? (June 2016)
Neal Stephenson and Graeme Devine on the bridge? Wizards, indeed ;)
fitzwatermellow··on Voxel art
See "volume graphics" and "volume rendering". More common in radiography than in games ;)
fitzwatermellow··on Snapchat raised $1.8B in a Series F round
Currently developing tools to do market research and user analytics on Instagram. Experience so far with the Instagram API is quite positive. Take a look at the endpoints on their dev page and its immediately evident: Instagram exposes a lot of precious data. Consequently, it is the platform of choice for users who accept sponsorship for posts. Also, when reaching out to the Instagram team about improving tag discovery and search, they were very amenable :)

If anyone from Snapchat is monitoring this convo, I would implore you guys to prioritize your API rollout. Provide the tools that allow your users to be able to make data driven decisions. Building an ecosystem of creators who can figure out how to monetize their Stories better than any one else can is "the key"

fitzwatermellow··on OpenAI Team Update
Came across a nice paper by OpenAI's Ian Goodfellow and Google Brain on using video prediction to model a robot's "after-effects":

Unsupervised Learning for Physical Interaction through Video Prediction

fitzwatermellow··on Airbnb: Building a Visual Language, Behind the scenes of our new design system
Thanks for the link to tachyons css. Was just searching for a modular system exactly like this. Plus, great name ;)

fitzwatermellow··on CryEngine out on GitHub
Where is the actual UI code for the Editor? Is it included?

Oh and thanks for all your hard work, I've learned a lot from you guys over the years!

fitzwatermellow··on CryEngine out on GitHub
I actually kind of find this sort of entity data oriented code easier to grok than when everything is nicely organized into object hierarchies, like they teach you to do in school ;)
fitzwatermellow··on Show HN: Illustrio – Search, customize and download illustrations
Nicely done! Can actually start using this service immediately ;)

How easy would it be for Illustrio to take requests for specific illustrations from the community?

fitzwatermellow··on How do you stop a randomized game from randomly being boring sometimes?
Fantastic question! Quick and dirty solution is simply to choose a distribution that isn't uniformly random!

Instead of starting with your random number generator, build up the discrete probability distribution function first. The histogram can have any shape you want.

So, for example, in Tetris, rather than choosing a uniformly random next piece, we give a 10% probability to a straight one, 20% to right-sided L, etc. Now we begin to see patterns that can make gameplay challenging or interesting. If a shape has not appeared in a while purely out of chance, alter the distribution. Keeping track of what cards have been played and what moves have been made forms the basis of a feedback loop that constantly evolves.

fitzwatermellow··on Ask HN: What are some rite-of-passage style projects for programmers?
Snake. Can pretty much pack all of CS 101 into that one little game ;)

My "hello world" for learning new languages and platforms. Integer based or floating point. 2d or 3d. Sound effects, sprite animation, physics, procedural particle systems, global leaderboards, digital skins and so on ad infinitum. Allows you to experience nuances in packaging and deploying WebGL vs Android vs Steam. Continue polishing it, and you may end up with something fun that others will love!

Can also be refactored into a full Tron Light Cycle style simulation. Which is a great way to learn AI. Good luck!

fitzwatermellow··on The slow death of purposeless walking (2014)
You have described my situation to a tee. It doesn't work in the city. It must be in nature, and I must be alone. Except rather than the nitty gritty implementation details, I limit my mental explorations during perambulations to the higher level abstractions of architectural matters. I even wrote a toy "mobile web dicta phone" that uses the media recording api because I wanted a single click, distraction free way to make "notes to self".

For any one in this situation, I think any "code while walking" solution should be voice activated, as it may be important to have eyes and hands free over the terrain. Straight voice-to-code would be cumbersome. Something like a voice-to-UML might be better. But I think what we really need is to first define a visual logic language itself that can be easily translated into high level code. Thanks for sharing, and keep exploring. There are definitely others who would be interested ;)

fitzwatermellow··on The MOnSter 6502
Fascinating! Just curious if anyone can provide any more details? Specifically, what design software, which manufacturer?
fitzwatermellow··on Ask HN: How to learn more about Crypto Currencies for a Newbie??
The Princeton Bitcoin class and companion text are very thorough. One of the crypto-currencies of note highlighted during the class was zerocoin, which adds a layer of anonymity to the blockchain. The Zcash implementation of zerocoin is currently launching in alpha. It may prove an interesting way to witness the progress of a crypto-currency being bootstrapped in real-time. As well as gaining insight into cutting-edge zero knowledge technology, that some believe may become standard in all future crypto-currencies.

fitzwatermellow··on Artem vs. Predator
Nice way to start the day ;) Can't someone send this guy a box of gently used CCDs and some wideband lenses already or maybe an old copy of labview...

Oh and Artem, if you happen to see this, can you try getting out of the city on a cloudless night and taking a long exposure of the night sky? Thanks for your hard work and inspiring us all!

fitzwatermellow··on Advanced Research Projects from DARPA's Pentagon Demo Day
20X less power consumption for the Photonic Computing device. Photonic ICs could be on the cusp of explosive growth...
fitzwatermellow··on HARC
I try to make a private study of the global survey of Wisdom Literature in an attempt to distil the essence of what it basically means to live a good life and be a moral person. Everything from Confucius to Aurelius, from Goethe to Gogol. And on and on. Wouldn't it be prudent, whilst you have such an assemblage of noble thinkers, to compile some sort of universal knowledge base of choice epigrams. For the purpose of henceforth explicitly delineating what it means to be "beneficial" and "just" for all future readers to come?

In any case, this looks like a necessary and timely line of inquiry and am looking forward to the fruits of these endeavours. Good luck!

fitzwatermellow··on Revlo (YC S16) is a fan-engagement platform for Twitch broadcasters
Just noticed Beam, a livestreaming platform, on TC Disrupt as well. This space is so hot right now...

fitzwatermellow··on Snapchat Pitch Competition
On the other hand, it could be really fun! Stories are limitless vehicles for creativity and self expression. Some were complaining before about the character limit. Video is much more intimate.

My only issue is that I don't think I'll have the time to view 100+ snaps ;(

fitzwatermellow··on Meet the YC S16 Batch
I have noticed Revlo on Twitch! ("what on earth is a goon dollar???") No brainer selection for YC. Looks like a compelling digital currency solution for fan bases. And this space, whatever you want to call it, "internet video viewer engaement", is gargantuan, nascent.

Just curious, without given too much away, what's the endgame with Revlo? Create the ultimate platform on top of Twitch, Youtube, etc. that content creators can then use to run karaoke contests, create mini games, raffle prizes and such? Or scouting and developing talent and creating their own studio and channels? Good luck and congrats!

fitzwatermellow··on The genomic era arrives, and this time is probably real
I'd like to see the cost of bioinformatics cloud computing come down by several orders of magnitude as well. The ideal scenario seems to be a global network of in-field mobile clinical units that can collect samples, run diagnostic tests and sequence genome data. Then upload that collected real time data to public data stores on AWS S3 or Google Cloud Genomics. Which a team of researchers can then access from their own labs around the world.
fitzwatermellow··on Ask HN: Anyone making a living off of desktop applications?
+1 for Spine. Will literally change your perception of what's possible in sprite animation and illustration ;)

fitzwatermellow··on Phrack 69 released
I enjoyed "The Fall of Hacker Groups". Clearly there is some deep nostalgia for the 2600 days out there ;)

"The only attitude consonant to our search for a comfortable, safe life is to constrain ourselves to our own limitations, ignore the intelligent life out there, and surrender to the mediocracy that our society has condemned our leisure time to."

fitzwatermellow··on Claude Shannon Turns 1100100
IEEE also had a nice retrospective:

fitzwatermellow··on Ask HN: How can a dummy like me learn algorithms?
Still in beta, but Google Code Jam has a new Tutorials section:

https://code.google.com/codejam/tutorials.html

Start with basic File I/O. Then begin working on the beginner level problems. Read the contest analyses when you get stuck. Best of luck! :-)
