> With an ion thruster you leave it on for all 30 days.

With a thrust of - at best - 5 newtons, you won't achieve the goal of getting to Mars faster. You may get there cheaper and using less fuel, but for pure speed you lose. Ion thrusters are good for very long trips when you're going to leave the engine on for months, or for trips where the total time doesn't matter much, only fuel economy (e.g. for cargo shipments or probes).

Having studied a foreign language (Brazilian Portuguese) as an adult, my experience is that learning written and spoken language are separate skills. Just because you know a written word doesn't mean that you will recognize it when it is spoken.

My experience is that I had to learn every word twice: once as text and again as audio.

This was despite the fact that Brazilian Portuguese is much more regular than English in mapping sounds to letters.

Quizlet and similar ideas look fine for written vocabulary, and helping you read, but don't kid yourself: you're not going to be able to listen and speak by mastering this tool.

You mean "Spam"? Already trademarked.
Yeah, perhaps something like a domain report card highlighting any problems their system has currently flagged for it and linking to solutions. Would be useful even on domains you've owned for a long time, just to help determine if there are any concerns.

For example, when Google first started the Panda updates, I read that some sites were being targetted via paid link buys NOT purchased by the actual owner. Would be nice if there was a tool that let the owner find out that was what was happening to his site.
Sounds like Google's problem.

"Remember folks! Don't use SEO! You're subverting das Googlebot!"

But play by all their algorithmic rules, or you may be randomly penalized.

This is called a False Positive. It's Google's fault, not the legitimate domain owner's. This is a hard problem(tm) for sure, but not an excuse.
I LOVE github, their little project forever changed the way I think about & write software, and their ideas (blogposts/presentations) about how to build software are truly a massive inspiration for me.

Basically my defense of traditional notation is that although it makes easy music hard to read initially, it makes difficult music easy to read in the long run. If a notation has to compromise, I'd rather pay the price at the beginning than for the rest of the time I use the notation. Also, I would ask, what problem does Hummingbird actually address (besides note naming)?
Cool, thanks. I had not seen anything official either - just pipe-dreaming that one of those commenters I saw knew something special.
Interesting but only works if you have a consumer or SMB product. Enterprise sales is a completely different game, where granularity (at least at the beginning, when you have just a few sales a year) prevents you from doing sexy dashboards like this one.
Itanic may be an exception, but there have been at least two backwards-incompatible C++ ABI changes in G++ over the years. Casting to superclass in the presence of multiple inheritance and exception handling have been among the changes. Maybe they should change vtables too, I don't know.

Clear, simple organization advice - from a professional non-techie
This is the closest I've found [1]; it's an expanded version of a SPAA paper by the same name. It's not executable, but it's pretty detailed and C-like as paper pseudocode goes :-/

[1] http://www.cs.technion.ac.il/~erez/Papers/lfbtree-full.pdf
That's what I was thinking. They're actually already doing something. On the other hand, their not-yet-developed Falcon Heavy can "only" lift 53 tons, about a third of the weight of FDR. Hopefully they can come up with a way to lift it in stages, or we still need a bigger rocket.
I read through the whole page and didn't get that. It didn't click until I started looking at the second page on the site (which goes more in depth).

My immediate thought once I figured that out was "this depends on English". For speakers of Japanese or Russian or French, can you find easy to remember words that can go with the first symbol, and that start with an "a" sound?

I actually found the terms extremely confusing. At first I thought the above/below referred to sharp/flat, but that didn't turn out. I couldn't even come up with concepts for dot and groove.

I know how to read music, but I'm not very good at it. I'll say that the idea of giving each note it's own shape seems like it could fix the problem of losing my place and having to count lines/spaces to figure out what a note it.

The thing I've never liked about musical notation is that the X axis has nothing to do with time. A staff can have 8 32nd notes and then a dotted half note. Those first notes take up 1/4 the time but 3/4 the space. While it would take more space, I find a consistent relationship much easier (such as piano roles or Guitar Hero note charts).
Not to mention eminent domain - where if your property makes sense for a freeway, pipeline, or, in a new twist, a shopping mall if doing so will improve the "Public Good" - someone can basically just pay you what they calculate as fair market value and tell you to move.

Buying the domain is the least expensive thing you can do. Building a brand and investing in launching a site on the other hand can be one of the most expensive things you can do. An amazing site can do well in spite of a bad domain name (example: pinterest!) but a well known domain doesn't guarantee a great website or brand.

I know you can have them login with FB or Google and you can get that info but I'm wondering if there's a way to get that data in real time without having them login?

I agree that it's a stretch and I would not personally characterize him that way, it seems to be the perception that is being sold to the masses.

I think how artists deal with these forms of 'infringement' speaks to their character. For example, I love Bill Watterson (Calvin & Hobbes), but I also think it is somewhat petty that he so angrily hides his creations from the world in any form. I mean he wasn't able to stop millions of stickers being made depicting Calvin pissing on car logos, but yet he wouldn't allow children to purchase a plush toy of Hobbes? It may be his prerogative, but when something artistic has impacted the lives of millions in such an important way, I believe that artists need to live with the fact that there will be derivative works. I mean I could argue that Warhol should not have been able to use the Campbell's soup logo based on the same reasoning in this article... I think the pixelation of the original image constitutes a greater abstraction than simply enlarging the image and changing the colors.

BTW, I am adopting the term "meatspace." I love it.

Everything I've read from folks at Mendeley misses the point of the disgust. Most people are not concerned about Mendeley going away, or about development stopping, or about new features not being added. Of course you're continuing to build the tool, at least the for the foreseeable future. Of course Mendeley will continue to be have a free version, etc. Of course Mendeley will continue to add features.

But none of that is because Elsevier has suddenly decided to support open access. It's because buying and developing Mendeley is an affordable way for Elsevier to launder its godawful reputation. All the smiling emoticons in the world don't change that.
You may have hit on something here.

There is no guarantee that any item will be worth any amount of another item. You can make claims about the relative likelihood that some item will be exchangeable for some quantity of another item, but you cannot claim that in every future scenario your item will be exchangeable for any amount of another item.

Just because a transaction looks more like barter than commercial doesn't magically convert the ideas underpinning fundamental economics. At this level of understanding economics is more a study of sociological systems and less about banking, fiat currencies, and all the other modern mumbo-jumbo we go on about these days.

This is really key when discussing some utopian reality where we've untethered ourselves from any form of currency--an exchange of value is tied to the very earliest societal systems. Unless society shrinks back into nomadic wandering tribes some form of value exchange (aka: currency) will exist.

How did you learn Github?
There are a bunch of design and typography rules out there, such as Kadavy's book. One of the harder lessons to learn is that the most valuable thing to develop is your taste... and then your relentless pursuit of creating great work based on it. The better your taste, the more frustrated you will get until your skills meet it. I found this after a few years of torture:

Git and GitHub have both made monstrous contributions to the software development landscape. I've acquired incredible new powers, for free!

What other power-tools are on the horizon? What's next?
Congrats on 5 years to Github! They are true pioneers for creating a social network for programmers, and not limiting it to just experienced programmers. I barely knew how to program but I was suggested to try Github with the little HTML/CSS/JS I knew and it is been my favorite, not to mention most effective, way to practice to become a better programmer. Collaborating with fellow hackers on projects is more fun than I ever imagined. They have actually found a way to make programming a social and fun experience! The beauty of Github is that it attends to programmers of all experience levels, so I really don't see myself straying away from it even as I become a better programmer. Here's to hopefully more than another 5 years!

As an afterword, I guess the big question is: What comes after this? What will make Github irrelevant?
There have been many occasions throughout history where things like this were not communicated because they were presumed to be obvious.

That's a great point, listening and speaking is much harder than just being able to read and match some words.

In many of these cities, it is impossible to flag a cab at any price during peak hours. It would be far more efficient for the government to top up the earnings of low-earners than to manipulate the supply of cabs.
This is just painful. Instruments do not have scales. Music is written in different keys, and often modulates to another key and back again during the piece. In order to cover the range of pitches, different clefs are used to make the notation easier to read. Piano music is written in two clefs, bass and treble, centered around "middle C". This is called the grand staff. Depending upon an instrument's range different clefs are used. Violoncellos use bass, tenor, and treble clef. Violas use alto clef.

Scales are a function that acts upon the set of pitches used in music. A C major scale has the pitches C, D, E, F, G, A, and B. A G major scale (function) has the pitches G, A, B, C, D, E, and F#.

"Mapping relative pitches to a scale" is nonsensical. A scale (function) is an absolute set of pitches, immutable.

There are two forms of solfège (do, re, mi, ...): fixed and moveable. In moveable the first pitch of the scale is always do. In fixed the pitch called C is always do. Watch "The Sounds of Music" to learn the solfège for a major scale, it's the do-re-mi song. There are other syllables used for the three minor scale forms. To my knowledge (admittedly not complete) Italy, France, and perhaps England used a fixed-do system, whereas the rest of the world uses a moveable-so system.

this is cool (and a nice endorsement), but our belief is that true killer applications will be multi-platform (which may include Glass's future competitors). We see Glass as a natural extension of the mobile web, not a closed garden by itself. Glass applications need to be able to tie into the lives we (and our friends) are already living. Given the adoption curve of most (non-Apple) tech gadgets, it's difficult to see Glass-only applications achieving sustainable revenue for their creators, which in turn makes it difficult to see this Glass fund as anything other than outsourced R&D - as in "let's have devs throw spaghetti at the wall and buy the ones that stick". Not much wrong with that, I just didn't think it was a16z's style. don't get me wrong: we love Glass, are spec'ing out multiple Glass-ready projects, and can't wait to get our hands on our dev units, but we believe sustainable businesses must be built on more than one pillar. If you decide to take the myopic approach, just be aware that your startup becomes but one roll in someone else's roulette game.
Eh. Correlations are notoriously weak, and the causation could just as plausibly be reversed (sleep is, after all, a brain activity); this may just be picking up conditions causing sleep abnormalities, which would explain in your first link why they also found an association with too much sleep as well ("Long duration of sleep was also associated with a greater risk of death").

If you want to complain about regulation, you're really complaining about people who don't want to take personal responsibility for their own actions. Rather than not buy Kinder Surprise treats for infants, they'd rather ban them for everyone just in case.

Regulations, in many cases, just reflect collective attitudes.
Honest question: If it's not for GitHub's community features that get enabled through git's decentralized repository, what does git do for you more than a local SVN server?

>A fusion reaction with a power gain < 1 is endothermic -- its temperature is less than that of its power source.

You are trolling! Or you just don't get it. The energy does not disappear. If you put in 1, and the reaction gives you .5, you have 1.5. You do not have to maintain a stable reaction, in the same way a hydrogen bomb doesn't have to produce however many terajoules of electrical energy to be more useful than TNT. It just has to be more total.

They are not making an electric generator, they are making a rocket. They are not the same thing.
I'm still looking for a regulation omni-apologist who can explain to me why it is rational to restrict the supply of cabs so that it is impossible to flag one during peak hours in many cities. It seems the taxis monopolies benefit and the politicians they support benefit, but the vast majority of us lose.

That's why uber exists and is highly profitable. Unregulated cabs at any price are better than regulated cabs that might as well not exist. And it doesn't hurt that uber has innovated on an industry that has been stagnant for a long time, like most regulated industries.

Not to mention this has no capability for helping you learn grammar or verb conjugations etc... ie. the stuff you'll need to know in order to write OR speak in sentences. Still pretty neat idea for studying vocab, but nothing more.

The UI is a bit heavy here and with 4 words to choose from, even without knowing much about the language it is pretty obvious what the correct answer is.

The standard music notation and the criticism this new notation receives here look to me as if we were stuck for centuries with only one programming language, C++, and nobody could change it.

Sure, it has been working fine for many years, and a die-hard fan of C++ would come up with many criticisms of anything new: No pointers? It's for beginners only. Garbage collection? I can see the programmers that created it are not very proficient. Etc. etc. etc.

And you know what? There are really great programming languages that do many things differently and also work very well, or even better than C++. They are not perfect, but the traditional way of doing things (C++ or the standard music notation) was not perfect either to begin with.

So, I hope people experiment more and more with new notations, and maybe they will improve the standard notation or even replace it someday.

In China, the Occam's razor explanation is that the lead is really there. China's population is freaked out by food safety because of all the food scandals that have happened over the years. Melamanine in milk, for which milk company executives were actually executed, reuse and reselling of cooking oil found in gutters, the list goes on and on and on.

I have no idea about the conditions in Taiwan, but in China, the Occam's razor explanation is unfortunately the negative option because it's proven to be so common. Recently for example, Hong Kong folks are super mad that mainland China folks are coming over and buying up all the milk powder for their babies. Why don't mainland China folks buy milk powder in mainland China? Well, there you go.

New Startup Looks To Kill off Patent Trolls
Nobody has mentioned this yet, but this is just one of dozens of past attempts at creating a new music notation. Even if you think that Hummingbird is worse than traditional notation, don’t be so quick to dismiss the idea of alternative music notations in general. Each author’s attempt at a new notation changes different things about traditional notation. Read more about some other notations here:

http://musicnotation.org/systems/ – a list of various notations

http://twinnote.org/ – TwinNote, a notation. One trait it has in common with many other notations is a chromatic staff: the distance between notes on paper always exactly corresponds to their difference in pitch, so accidentals are not allowed or necessary. TwinNote comes with template files for the open-source music typesetting program LilyPond, so music written in LilyPond format can automatically be printed in TwinNote.
