I guess I'm never to actually get Lisp to appreciate its syntax.

>Aside from the prefix ordering, Common Lisps syntax is already a bit more elegant because you can set arbitrarily many variables without repeating the assignment operator over and over again:

 ; Have to type out `=` three times x = 10 y = 20 z = 30 ; But only one `setf` required (setf x 10 y 20 z 30)
I utterly fail to see the aforementioned elegance, although I certainly can't miss the line where it happens.

The Japanese Urban Zoning System marginalrevolution.com

Japan's property values haven't risen in the last 20 years because their economy is in the toilet, they're struggling with deflation, and their population is declining.

When the economy was growing like crazy in the 80s, Japan had the most expensive real estate on the planet, and the same zoning they do now.

Very neat. I love reading about cities and urban planning. I have "The Death and Life of American Cities" by Jane Jacobs laying around which I need to read and I read another book about architecture here in New York City and how it has evolved over time in response to things such as fires and 9/11. Really really very interesting stuff.

This was a great post. Mixed use cities are generally much more desirable in my eyes. The American suburbs are a blight on the land which make our nation so much more carcentric than it needs to be spreading the population out and reducing the efficacy of our now underfunded and sprawled out public transportation system.

Of course it's not a shocker that such a system evolved in a nation with such a staggering amount of land available to it's citizens who live and have lived in a nation with huge amounts of racial segregation.

The idea of a set of national guidelines makes sense from an engineering perspective because small towns can't afford engineers often (or may not even think to seek out their expertise) and in the end you have a group of individuals with no qualifications determining the fate of their town with arbitrarily decided rules.

And rating things by their nuisance (traffic plus noise) levels is a really neat way to quantify whether a building should exist in a given area.

Awesome! Lots of new things to entertain the mind.

It's not untrue to say that Japanese society as a whole does have a culture of Confucian orthodoxy/heirarchy, ie. people do not 'rock the boat' or 'aggressively agitate for change'. This means that tradition survives well and a cultural premium on internalizing discontent and preserving outward peace rules the land. Urban zoning is probably one of the areas most affected by this cultural property. That said, in my mind even traditional Japanese urban architecture is pretty well optimized for high density, itself largely based on Tang Dynasty Chang'an in China, arguably one of the greatest periods of multicultural tolerance and philosophical debate in the history of the planet (terminus of the Silk Road, vast exchange of ideas).

I'm glad Tyler is talking about this, as he tends to be the leading edge of a lot of policy discussion around newish ideas, and the Japanese zoning system is a marvel of both efficacy and simplicity.

While the Japanese system is implemented and managed on the national level, I can imagine this being more effective on a more granular level, while still being much higher up than the city level as to avoid the political repercussions of local special interest landowners.

When I was a boy in the Soviet Union in the late 80's, I picked up a book on computers. It was targeted towards children, and talked about a lot of different components and ideas from bits and bytes to RAM to networking, and interesting applications like barcodes.

I remember my mind being blown by barcodes. But the idea seemed far-fetched and unrealistic. To put a barcode on EVERY single item in the grocery store? That would take decades to implement!

Then we emigrated to Canada and I was shocked to see it was already in place (and must have been for a while).

Maybe this isn't the best example of tremendous human achievement but it taught me to not take for granted what is unrealistic and how quickly humanity could achieve it if we put our minds to it.

With apologies to Cliff Stoll and his magnificent brain, let's not forget a pretty common perspective on the Internet from 1995: http://europe.newsweek.com/clifford-stoll-why-web-wont-be-ni...

Space exploration and rocketry is not cheap, and requires new innovation. Only SpaceX is doing anything on that front. But if humanity set getting to Proxima Centauri as a goal, I have no doubt we could achieve at least kicking off a single-generation journey within my lifetime (ie sub-80 year journey time in the next 80 years)

This is nonsense. The point is that the exoplanet was (potentially) found orbiting the nearest star, which means it's as close as it can be.

The physics of space travel are harsh, and the distances involved even harsher. Plus, unless you want to go screaming by on a fly-by mission, you have to burn all that delta-V you generated to get there in order to slow down again.

The only real solution will be some kind of essentially magical faster than light technology - never say never, but it doesn't seem likely without some staggering breakthroughs in areas of physics we don't even have an inkling about.

Maybe it's the American exceptionalism and internalization of Manifest Destiny as the natural order of things, but the idea of being effectively stuck, as a species, on this one rock for eternity is pretty depressing. Especially if that is the fate, not just of ourselves, but of all life intelligent enough to look up at the stars and imagine walking among them. If the best we can hope for is a Motey-like[1] Malthusian cycle, it's not much to look forward to.

Sounds like a riveting to-do list, with lots of big implications for the folks back home.

> We'd need a whole raft of breathroughs, including radiation shielding techniques to kick the interstellar medium out of the way of the probe

Game changer for nuclear power and propulsion, in terms of safety. If we did this with matter, that means we can get closer to hot things [1]. If we did this with energy, ha! - we can now start harvesting edge-of-magnetosphere antimatter and explore mining and terraforming using directed energy.

> as well as some sort of beam propulsion system

If we can beam massive amounts of power out that means we (a) have massive amounts of power up there and (b) can beam (a) home [2].

> and then some way of getting data back home across interstellar distances

Either we figured out how to keep lasers (or some other stream of stuff) columnar over super-long distances or we broke new ground in information theory. Either way, getting a grainy picture home from Proxima Centauri on an apple of an energy budget means getting lots more closer to home around faster and more efficiently.

Holy cow, that's multiple times longer than humanity has even existed as a civilization, and in all likelihood it might perish before that probe could even make it there. What a reality check. I don't think incremental improvements are going to cut it for space travel.

> Currently, the most distant visited body in the solar system is Pluto, at 7.5 billion kilometers. The New Horizons probe flew past Pluto on July 14, 2015. It was launched on January 19th 2006 by a booster and upper stage combination that blasted it straight up to solar escape velocity, with a speed of 16.26 km/sec (58,536 km/h), making it the fastest human-made vehicle ever: it then executed a Jupiter gravity-assist flyby to slingshot it out past Pluto, where it arrived nine and a half years after departure.

It's disingenuous to talk about Fukushima as a "meltdown", or imply that it was dangerous (on the scale of space-travel dangers).

The Project Orion design was for 10% of light speed, and didn't assume any scientific breakthroughs like fusion - it would require a massive amount of engineering , but the core technology (that used in nuclear weapons) was mature in the '70s.

We're still talking about a 40+ year journey, for a craft whose cost was estimated at $367B at the time - about $2.5T now. It's not easy by any means. But it is doable. We'll get there.

I wasn't aware this reality check was needed, but it's worth noting that we haven't even left Earth yet (going to the Moon doesn't really count, and we've since lost that capability again). If we were a solar-system-wide civilization, I can see how it would make sense to talk about the feasibilities of interstellar travel, but today we are so far off it's not even an issue. We also don't have any ambitions to change that, so extrapolating from today's state of affairs, we'll probably remain thoroughly Earth-bound until we reach a tech level that enables individual people to have space programs (if we ever get there).

It's fun to think of probe-based exploration, but apart from acceleration/energy based problems we haven't even figured out how to make machines last that long. This is all very, very far off.

NASA should over the next 100 years build a hyper-telescope, so that people can begin to actually see these planets in detail before before a probe can be sent.

Even with current technology, a hyper-telescope could be self-assembled in space, built from billions of 3-d printed & smoothened mirror segments, all aligned to half wavelength of visible light. We need to have a 1000px x 1000px resolution of earth-like planets out to 100 light years away, which would be several thousand miles in diameter.

Focusing on habitability from our perspective seems somewhat parochial.

From the perspective of colonization: by the time future sentients descended from or created by present humanity get to other planetary systems, we-for-some-definition-of-we would be capable of living anywhere, and space and novelty will be things that you get by computing more efficiently, not by going places.

From the perspective of adding data to the Fermi Paradox: assessing the possibilities of life being out there by looking for places in which bacteria of the known varieties could survive probably tells us little about the true range of life.

From the perspective of resource assessment: by the time descendant entities get to other systems, it won't much matter how the matter there is distributed. It will used efficiently whether a gas disk, rock and ice condensations, or (improbably) somehow all in the star.

As someone who speaks Chinese, I got a chuckle out of reading 'put your favorite snack in your and t it!' due to the association in my mind of that character and its Chinese pronunciation, immediately followed by a 't'.

primitivesuave 6 hours ago 4 replies      
Another interesting aspect of traditional Chinese characters is that complex words are expressed by combining simpler symbols. For example, the Chinese word for computer is . The first character represents "electricity", and the second character represents "brain". Which is really what a computer is, an electric brain. Similarly, a computer programmer is , where the three symbols are "rule", "order", and "person" - one who orders rules.

An interesting consequence of this is that you only need to learn around 3000 symbols to read a Chinese newspaper, just like how you can ascertain the meaning of an unfamiliar English word by having knowledge of a small set of Latin/Greek roots.

Another interesting side-effect that the compactness of Chinese symbols(other variations: Hanja in Korean, Kanji in Japanese and so forth)allowed was a higher chance of survival against natural disasters like wild fires or crimes like thefts or vandalism.

It was/is far easier to ensure redundancy of scripts and books since the costs of reprinting/copying was far lower compared to other forms of phonetic systems.

The compactness explains how so many archaic, buddhist scripts could survive to this day.

The problem is that many characters look similar but have nothing in common. For example, the article mentions the character meaning "food".

And another similar character meaning "long" or "leader" also has no relation to previous two.

And when you get to more complicated characters like it becomes even more confusing.

I just discovered NativLang on YouTube so this really is in my zone of interest today.

I've just spent the last few hours learning all about languages how they developed and each culture's spin on adding as much meaning as efficiently as possible to written symbols. I've always loved languages so this was more of a brush up plus learning.

It seems and rightly so ambiguity is death to any characters and efficiency is also fundamental to the character.

I'm not Korean but I like their style literally I like how their language style is so efficient in context to mouth position. It was created because Chinese characters didn't suit Korean language. Japan also streamlined Chinese characters to better suit their culture.

Mayan is another wild language full of meaning in such compact symbols. I had a hard time following their characters.

MySQL founder tries a new software licensing model techcrunch.com

evanelias 55 minutes ago 0 replies      
Applying BSL to the MaxScale proxy is proving to be, so far, an unpopular decision among a large segment of the MySQL community.

The TechCrunch article didn't address this specifically, but the license for MaxScale requires a MariaDB Enterprise Subscription if you use MaxScale with just 3 or more database servers at your company.

Since MaxScale is a proxy, it isn't particularly useful for companies that only have 1 or 2 database servers, except as a very limited trial. So this move effectively makes MaxScale commercial software for most production use. This is a strange business decision, considering there are other third-party proxies available, such as ProxySQL, that have same (or better) functionality and no requirement for purchasing a commercial license.

I also wonder how MariaDB Enterprise Subscription pricing works for companies that just want to use MaxScale to connect to stock Oracle MySQL or Percona Server MySQL? Seems strange to tie the licensing to MariaDB Enterprise even for companies that just want to use MaxScale alone. Although a good proxy takes a lot of development work, it's still tiny compared to building a relational database. I wouldn't expect the two to be priced the same.

Its easier to procure paid for software than open source in many large enterprises.

There was a culture of fear for open source promulgated by proprietary vendors and major consultancies in the early 00's - the "know the facts" campaign by Gartner and Microsoft springs to mind.

Although this idea is generally dead now, the scars live on in the purchasing and licencing approval flows at many large enterprises.

I am familiar with several organisations where a paid for software licence can be acquired with nothing more than trivial approval for the spend. Yet adoption of an open source product requires multi layer approval of the licence and recording of licence risk against the project.

There is a valid case for that due diligence but its not a particularly strong case and if it were the reason for this situation, then proprietary software licences would be subject to the same scrutiny.

I don't say this lightly, but wasn't the open source license of MySQL the main source of its success? As I recall, it didn't really get huge until they loosened up the licensing terms. And wasn't that one of the main reasons it made $1 billion? Not criticizing his business is his business. Just curious.

This is great from the perspective of contributing intellectual property back to the ecosystem. They are trying to balance the revenue aspect with growing an open community which benefits the product as a whole.

My one concern is that the thrifty users will ride the expiration line, installing versions that don't cost money but which are outdated. I can see where that would be an acceptable tradeoff in many situations where the latest-and-greatest is not required. But from a security aspect I wonder if that also means that vulnerability fixes would only be available to the paying users. They are definitely worth paying for, no doubt; but would that then foster an ecosystem of not-really-patched installations out there?

(Then again, that might not be that different from the current situation.)

I think it is a great idea, you can charge when people use it in production and it reverts to oss on a specific date.

I worked at a startup and companies would want us to put a version of the software into escrow and were wary of us going under, giving them something like this would have been perfect.

Is he trying to sell mariaDB now too?

I mean, it's genius from the business side. Unless i got the story wrong, he sold MySQL after people helped him create it. Forked it, and now it's turning the fork into MySQL/Oracle profit cow.

Either somebody correct me, or I'm going to assume "for as long as there's are sheep..."

This might create some complicated situations when the older versions become free and somebody decides to fork it to fix bugs that are present in the old (free) version, but fixed in later (not-free) releases. I believe then you end up with the question was this fix back ported from new version or did the developer come up with it independently.

Interesting concept, like how code will turn into GPL after a few years. Glad though that MariaDB is and could not be BSL.

This is a little off topic and maybe controversial because it is against the spirit of open source but in all earnestness if you make a software that you want to make available to all open source projects but then you want to charge a recurring monthly fees if the software is being used to make money - is there a standard license for that?

I've seen sites do this like readme.io but can you do that for a software library?

Very interesting. It's a bit like the fair source license model https://fair.io but more open in event the project looses traction is abandoned etc...

Sold. I will be moving my project searchcode server over to this within a week.

Giving up revenue from customers that don't want to change and are happy to pay is a huge loss. AOL still makes 600m/yr from dial up.

The open source freemium is cool, though. Those are two powerful forces.

They are switching to a BS License?

Are we supposed to take this seriously?

When I see the abbreviation "BSL", I can't help but think it stands for "bullshit license"....

However, it actually sounds like a great idea to me, and a great way for companies to make money licensing software to commercial users while still keeping it free and open source for individuals, while providing a safety mechanism in case the company goes belly-up.

Going to be interesting seeing how they will figure out where to draw the line (in legal terms) between testing and production. Would health checks be considered as testing the system or production type work?

Do municipalities collect and release any data on how people move around the area? For example, start and end points, with usual times for leaving or arriving. A large enough sampling of something like this seems important for planning, and I assume the real planners have it.
