possibilistic··on Two million Raspberry Pi sold
Do you have any pictures or footage? I'd love to see.
possibilistic··on Ask HN: Thoughts on Meteor.js?
How well does Meteor scale? Could a multiplayer game written with Meteor handle the HN crowd hitting it? I'm thinking of writing something like this and Meteor would be perfect if it's amenable to authoritatively sharing state between thousands of connections.
possibilistic··on Elon Musk on First Principles
I love this explanation. Do you happen to blog about optimization topics?
possibilistic··on Vi Hart: cramming G+ into YouTube has made comments even worse, I'm leaving
That's kind of a terrible side effect, isn't it?

I understand the existing policy as it is used to prevent editorializing, but it's unfortunate that this burying of interesting/original content can also result.

possibilistic··on Ask HN: What's the best place in the U.S. to live and work cheaply?
I'm trying to connect with other Atlanta-area hackers (I'm presently in Midtown and work at Tech Square). Care to chat over coffee sometime?
possibilistic··on Two years of production Go at CloudFlare
How do you manage large-scale Lua code bases effectively? Is there any thought or literature on that topic? I'd love to learn if you can share.
possibilistic··on Tidbit: Client-Side Bitcoin Mining
How do the various cryptocurrencies compare? There appear to be quite a few of them [1,2]. Are BTC, Litecoin, and Primecoin the best/most popular?

possibilistic··on Tidbit: Client-Side Bitcoin Mining
I'm only casually familiar with ASIC mining, but I do recall hearing that the best position to be in is selling tools to the miners. Still, I'm curious; how much would you have to invest into modern mining hardware in order to see a return on investment? I'm going to assume you either need a lot of these or have to join a pool.

Is this a game only playable by those with tens or hundreds of thousands of dollars?

possibilistic··on 2nd Annual Aaron Swartz Memorial Hackathon starts tonight at Internet Archive
Good clarification. I thought it was a bit in poor taste to call it "second annual" this early.
possibilistic··on Require.js Library Skeleton
Entirely earnest question -- wouldn't it be disadvantageous to create a library using Require.js? AFAIK you can't compile out the Require.js dependency. Even Almond.js leaves this cruft. Shouldn't you design consumable libraries to be entirely clear of runtime dependency mapping/loading?

As a part of my workflow, libraries are built at compile time by a Grunt task. These modules are concatenated based on an externally specified dependency graph. The end result is no Require.js in the final production code.

I'm kind of against R.js as it adds complexity at runtime. Has anyone found a way around this? If it were compile time overhead alone, I wouldn't be so opposed.

possibilistic··on Mint sucks, so why aren't there any real competitors in that space?
I would like something like Mint that comes with a consumable personal API that is safe to call. I want to generate my own reports, but I certainly don't want to handle banking-level security.

In case you aren't familiar with this meme, it's the Shiba Inu meme, termed "Shibe" or "Doge".

possibilistic··on Ask HN: What are you working on and why is it cool?
I'll definitely look into these guys. I'm unable to relocate right now, but there might be some future opportunity waiting.

Thanks for the heads up!

possibilistic··on 0h 0min 0sec Game Jam.
The concept is to build a game in the one hour that "doesn't exist" during the daylight saving time change.

This seems pretty fun. I like Game Jams, so I might be doing this. Definitely need to get an engine squared away before hand, because there isn't much you can do with one hour unless you already have a proven framework.

possibilistic··on Ask HN: What are you working on and why is it cool?
Some of the hardware was built (one of the projectors), some of it is purchased (a second projector due to time constraints, and all of the DACs). The games, graphic engine, DAC comms, etc. are all programmed in a mix of Python and C++. Most projection software available is commercial and expensive, so I've rolled my own stack.

I'm working towards surface distortion mapping, which is increasingly important in the umbrella concern of rectifying multiple projectors onto a single coplanar/colinear surface. I'm going to project a series of grids and have OpenCV automatically align all of the projectors. From there I'll be working with a logical "frame buffer" (really coordinate/transform buffer) that is relayed over the network to a graphics server that will dispatch the drawing jobs and topologically sort objects unless they have preassigned projector-affinity.

As far as I know, nobody else is building a beowulf cluster of laser projectors for interactive display. That's my endgame. Really fluid, bright, fast laser light with incredible geometric output capacity. It won't be limited to 2D if I can get design a decent wireframe or clipping/culling engine.

possibilistic··on Ask HN: What are you working on and why is it cool?
Laser projection.

I've just added a second projector and a few more dacs (thanks to a very generous donor). I'm doing multiprojection and rectification/distortion now. I'm planning to get Skyscraper Tetris and Breakout going with some additional hardware.

I need about ten projectors at 60kpps (or 80kpps at low scan angle) with a combined wattage of 20W or so. I have endless ideas: I'll bring it online, do live art/graffiti, turn buildings into twitter feeds, multiplayer gaming, and NES emulator, etc.

I wish I could afford more hardware and the ability to work on this full time. :(

possibilistic··on Show HN: A Github for writers?
Whoa guys, you send way too many emails!

In the last hour I've received about 15 emails, and they're still coming in. Please don't subscribe me to every event by default!

possibilistic··on Stop "Disrupting" Everything
Never.

You're missing the point of what it is to be a hacker.

possibilistic··on Finalterm - modern terminal done right
This is really cool.

I haven't evaluated it personally, but I don't think it's up my alley (I use a tiled WM); Vala and GTK make it seem like it's for the Gnome stack, and it also has mouse interactivity. Finalterm might be neat for an Ubuntu box, though.

Are there any comparable terminal emulators that support completion, 24-bit color, are hardware-accelerated, etc? I'd definitely like to replace mine if so.

possibilistic··on Facebook is using D in production starting today
Android isn't written in Java. The userland might be, but the kernel itself is Linux, and that is written in C.
possibilistic··on Facebook Removing Option To Be Unsearchable By Name
Even if selmnoo's account is deleted, the pictures that friends took and/or tagged will still be online. I believe that was the objection.
possibilistic··on Firefox OS Update Adds New Features, Performance Improvements
It's times like this when I really wish I wasn't on Verizon and locked into their proprietary wireless protocols. I would love to buy this hardware and check out FFOS.
possibilistic··on Day 180: Finished
Where did she find the time? Is she a student? Was every one of these projects done on a consecutive day--including weekends? (I'm unfamiliar with this project.)

Regardless, kudos to her--this is a great way to learn.

possibilistic··on Judge tosses Apple motion, allows patent troll Lodsys to continue rampage
I like this idea a lot.

If the population living in the causative region understands the nature of what their governing body is doing to impact and infringe upon on the rest of the world, maybe they'll change who holds the relevant positions of power.

It would be great if we could do this to websites and technology in general as well. Maybe we can start with this kind of campaign [1], but utilize geo-IP targeting.

possibilistic··on Steam Controller
I have, and I strongly prefer the TrackPoint--by a whole order of magnitude. I never have to keep my fingers off home row.

I do use a tiling window manager and bindings like Vrome/Vimperator, so my use case is probably atypical. My mouse usage is limited to when I deem it absolutely necessary; I hate physical/mental context switching, and bringing my hand from keyboard to TrackPad/mouse/whatever is a huge context switch.

possibilistic··on First Mechanical Gear Found in a Living Creature
I don't think you can really get away with saying that.

I think a better phrasing would be, "the summation of all adaptations in addition to environmental state (including benefits or constraints to itself and all others) has led to the survival in its present environment".

It's really about optimization gradients in a particular time/environmental/social niche. Everything can change with the purturbation of any factor--but that's evolution for you. Adative curve fitting.

possibilistic··on Intel: [We] will not carry XMir patches upstream.
Perhaps Canonical shouldn't have used FUD against Wayland (which is heavily contributed to by Intel).
possibilistic··on W3C Approves RDFa 1.1 for HTML5
How do you like working for UniProt? Where are you guys based?

In the future I'd like to work at a place like this, so if you could tell me more I'd be grateful. (My email is in my profile.)

Thanks!

possibilistic··on The Road to Ember.js 1.0: Final Release This Weekend?
After Backbone, as you start to get into the realm of dozens and dozens of models, which is more appropriate?

I've heard Ember is better for "data/model-driven" apps whereas Angular is better for "interaction-driven" ones. Is this an appropriate analogy? I wish I had the time to explore both for their own merits.

If you were going to develop the next Gmail, which would you choose and why?

possibilistic··on Converting an existing Backbone.js project to Require.js
Perhaps someone can clue me in, because I'm still at a loss for why there's so much hype built around Require.js.

I develop JS primarily for the frontend, and I use Grunt, a global namespace, and concat (or similar tooling) to piece things together.

Doesn't r.js execute dependency resolution code at run time? Can all references to r.js be fully compiled out? Even a wrapper like Almond seems to leave behind this kind of extra cruft. I don't want any dependency resolution code in the production build, because that's a problem that needs to be solved at compile time.
