Here's a 24-cell you can explore:

http://fleetinbeing.net/hypersolid/examples/24cell.html

It doesn't bring out the cells or faces, but it does show edges in parallel coordinates. Edges show up as multi-points in the plot below. Above is a 3-d projection of the 24-cell which you can click+drag to rotate.

This is the operating system made to run Dwarf Fortress.

That works, but I couldn't get audio to work. So no listening to Songs by God and Me or anything else in the OS.

You may be thinking of the new Nexus 7, which is also competitively priced at $229

"Yes, and" refers to one of the techniques of improvisational theatre.

https://en.wikipedia.org/wiki/Improvisational_theatre#Applyi...

Basically you must accept the reality your scene partners put forth and build on it. Otherwise you end up with a confused, amorphous environment with no clear direction.

Improv theatre still needs tension and conflict to emerge. This comes out of the structure of the scene spontaneously. It could be some kind of repetition, pattern, contradiction, physical motion, etc. Ideally, the players don't just rehash old games but are eager to make a new, unusual play.

"Unusual" in this sense relates to the context of the world you're playing in. In a scene, it's not unusual for a coven of witches to kidnap children and boil them in a brew. But it could be unusual for a scientist to discover that brew has miraculous healing properties and to publish the results in Nature. This could be humorous to an audience, because normally there's absolutely no legitimate utilitarian imperative to mix children into a brew.

There are more interesting ideas in improv that relate to politics/business. I recommend anyone interested check out Impro For Storytellers by Keith Johnstone.

The ultimate intuitively simple and intellectually challenging game is Go. Go's rules are far simpler than Arimaa's, and it's just as challenging for computers.

losethos mentioned this too, although he is hellbanned. His point was that Go's advantage is it engages the image-recognition abilities of our brains.

Brush transitions are a nice feature http://bl.ocks.org/mbostock/6216724

D3 is definitely a library, though not a framework. There are conventions, but there are also magical abstractions that work together like selections, data-binding and transitions. I would not call the eight lines of code you need to write for a basic visualization and transition "low-level".

Composability is achieved with configurable functions. Is there an alternate solution you propose? What helper would be useful for data that changes over time?

I remember the latency being around 4-15ms depending on the number of hands in the frame. That's very low, but if you compared with 1-2ms latency it would be noticeable. Applications can add additional latency on top of that.

If the year was 1896, I probably would be happy. Brakes were far less functional and reliable in the first 20 years of the automobile's history.

In one amusing video, he proposes that Satoshi Nakomoto, the creator of Bitcoin, is a pseudonym used by Shinichi Mochizuki, the mathematician who found a proof for the abc conjecture with his inter-universal geometry.

The exposé looks like it's laid out slightly differently than OS X and includes buttons to close the window.

The multiple desktops is on the bottom and not part of exposé. It includes a new desktop button. It has a dark background rather than blending in with the desktop. It appears you can drag app icons from one desktop to another-- I've never seen that feature before.

The header is black/dark grey, not silver. The colors, gradients and layout of their music player and iTunes look significantly different when compared side by side.

The file manager is greyscale: it doesn't appear to use blue tones like Finder, except for folder icons.

Windows in OS X have 4 buttons, all different colors. Windows in Elementary have 2 buttons, styled the same.

This may seem like a pedantic critique of your comment, but my point is that it's clearly not a "carbon copy" of OS X. The statement "none of the effort was done for design" is not a fair criticism of the Elementary development team.

You can use queues when creating a large number of elements. Use requestAnimationFrame and each frame pop some elements off the queue to render them. This will help prevent the page from locking up during render events.

I've used both. I prefer the Mini's screen to the old N7: larger viewing angles, better color saturation/accuracy, less backlight bleed, smaller bezel.

The iPad Mini Retina will likely be the perfect small tablet for most users.

The Edge is designed to be used as a desktop as well.

It also has a true Linux terminal and runs Ubuntu.

Quite different than other phones.

Your third complaint can be resolved by placing the device lower than your elbow. Most people use it on the desk, which is the problem. It's not the ideal height for the Leap.

When it's higher than your elbow, your shoulder must be engaged and power all your movements. There are also many apps that map directly from x/y/z space. These can be hard to navigate. All your joints move in arcs, not straight lines.

You get to use the Leap however you want, so figure out what's comfortable for yourself.

Leap is quite sensitive. You could look for tiny flicks of the finger, for instance to create a virtual DataHand. These kinds of interfaces should be much gentler on the body than apps which require large sweeping motions, punches, etc.

I want this. I already pay an Ubuntu premium for System76 computers. Anyone who has the Dell dev edition does the same.

But, Canonical, can you please extend the $600 price point for at least a month? This sudden 24 hour sale is too much of an impulse buy.

Paragraf is a great app to make graphic shaders. It's easy to use touch x/y coordinates and the camera feed as a texture.

The results look beautiful on retina displays. I've gotten several kids hooked on it, even overcoming some of the GLSL syntax hurdles to get their programs to work. I also gave them cheap $5 jeweller's loupes so they could inspect pixels as the program runs.

Lots of kids genuinely want to create stuff.

I tried to learn Java when I was kid and spent almost 3 hours trying to get Hello World to compile. I tried again for an hour the next day, and couldn't do it. I also didn't understand what words like "void", "static" and "main" meant. It was all voodoo mojo I didn't have in me. I thought I must have not been talented enough to understand these words.

You need to compile a program to get any feedback at all.

I did learn some HTML and JavaScript, because it was so easy to get started. I made table-based layouts and all that. But JavaScript wasn't a serious programming language at the time-- I really wanted to make a Java applet. The toolchain was just too complex and intimidating for me, so I gave up. Years late, I picked up the old Java book again and realized it was no good anyways.

I could have learned C from K&R when I was a kid, especially if I used Linux. I was always interested in Linux, but my family was paranoid about "breaking" the computer. I would have also been plugged in to open source culture at a much younger age. With Windows, it was all about freeware.

What stops identity thieves from using these records too?

Those are simple because they are physical artifacts, but let us consider the process of using those for trade.

A thirteen year old wants to send $4 to his friend. He wants to put money in a pool to buy a 4-pack of Terraria on a Steam sale for $10. He will receive one of the copies for his $4. His friend lives in another state.

He buys an envelope for 20 cents. He buys a stamp for 46 cents. He tries to look up his friend address on Facebook. It's not there. He sends his friend a text message, asking his address.

He addresses the envelope with his friend's address and his own return address. He licks and places the stamp in the top-right corner. He folds the dollar bills in a piece of scrap paper from the printer. He seals the envelope and drops it in a mailbox.

Several days later, his friend receives the $4. The friend deposits this with his own $6 to get a Visa prepaid debit card. Friend uses the prepaid card to buy Terraria on Steam, a gaming service which requires an account and email address.

Now, consider a transaction of $50 for a baseball card. Sending cash in the mail requires two stamps and two envelopes.

Who sends the letter first? What happens if one letter doesn't arrive?

Even stamps and baseball cards can present challenges for real-world transactions where physical co-presence between two parties is not possible.

It may have been published at the Post for the first time, but Guardian released this over a month ago.

Abe gave a talk at OpenVisConf about Skyline and how to make use of 250k metrics http://www.youtube.com/watch?v=Rij604NBXqk

Where can I find more about these straightforward routes?

Two ways off the top of my head, both mentioned in the article:

Arbitrage: balancing the prices between exchanges. This helps settle all exchanges on the market price, so you don't pay $5 more just because of the exchange you're on.

Market making: By placing both bid and ask orders, algorithms can tighten the bid-ask spread around the price. When the spread is too large, people are disincentivized to trade because neither buyers nor sellers can agree on a common price.

I would guess that day traders lose out, since they miss the opportunity to act on many of these same opportunities. Also I've heard index funds lose several basis points to HFTs when rebalancing.

It's a nice touch that such a large percentage of the Paypal price goes to the miners.

Atmospheric interference makes it impossible to observe in some wavelengths on the ground.

They just updated the status page in the past 3 minutes. The one you referenced is now here:

I have more news on the Mt. Gox transition. Today, CoinLab regretfully filed a formal complaint in Federal Court against Mt. Gox.

In the last month, many of you have contacted me directly and asked for more details on our transition, and I would say (charitably) that I've been frustratingly vague -- I just haven't been able to talk about it.

I'm going to take this chance to talk about it. I'm not here to complain, our filing contains and accurate summary of events, but I want to talk about what I see as most important for Bitcoin right now.

Bitcoiners have, on average, lost more money due to technology difficulties, frozen / lost banking relationships and shady characters like pirateat40 than due to any part of Bitcoin's fundamental economics. I hate this fact, passionately. I have a vision in which high quality service and technology and ethics can be delivered to you, me, my kids, everyone who has a stake in Bitcoin.

It is my goal for CoinLab that we provide fundamental infrastructure to minimize these risks for everyone in our space, and I do mean everyone; from those on the Bitcoin Forums who dislike and distrust me personally, to the mom and pop cupcake makers in San Francisco, to my daughter who recently sold some knit products for .01BTC.

While I was willing to take a two year restriction on our venue (US and Canada only for two years was part of our contract), I have for a number of years now wanted to make sure that Bitcoin is properly situated for everyone's good.

When we spun up our initial alpha customers, they included companies that from one perspective could reasonably be deemed to be our competitors, some of the best companies in our space. We worked extremely hard to provide them great service, because I want to build our ecosystem; I want a robust economy and a broad base of service and product for everyone.

What tipped us into filing was our complete inability to get Mt. Gox to deliver on the few simple things left that were needed for customers to move over en-masse; we were often left just apologizing to our alpha customers while their own businesses suffered. I'm just not willing to put any of our customers in that position -- if we can't do a good job for you, I won't promise that we can.

What I hope is that Mt. Gox has this same interest in the good of Bitcoin, and Bitcoiners, and finds a way to work this out.

So, what's next? I hope that we'll be able to provide some good news on that front soon, from a financing and technology perspective at the very least, and ideally with news that we've settled this dispute. In the interim, my biggest hope is that Mt. Gox does an excellent job keeping Bitcoiners safe and liquid and trading on the exchange.
