I posted this below to ux, but I'll repeat it here so you see it.

Sorry, but I was unable to find which ones were at issue. I wrote this code in 2005 - 2006, and have forgotten the relevant details by this point.

The info on how I did the symmetry and rotation was posted here, where it looks like I said there were six differences, but was still unsure of the exact number: http://forums.nesdev.com/viewtopic.php?p=82794#p82794

I'm a bit too swamped to do it myself, but if you or anyone else would be up for repeating my steps to determine which rules have the symmetry issues, please do post here.

Doesn't this suggest that those areas were previously habitable as recently as 1200 years ago?

If so, what was the climate when those artifacts were left there and how long was that area habitable? And what caused the climate to change from habitable to frozen?

It'd be a first if it works properly. NM has been a pain point for me for years. There is always something that doesn't work properly.

Also it's impossible to debug easily. VPN not connecting? NO DOCUMENTATION.

Typically when something doesn't want to work as well you end up with a "download the latest VPN RPM" situation which doesn't actually compile against that version of NM because the API is unstable as hell.

You very, very rarely have to use the Tag property to make a list. You either use Tag as a View-cache system (the View Holder Pattern, which is total overkill these days), or because your data object model is broke as hell (aka, you suck at object design).

Everyone else just uses CursorAdapter which is easy to use and ties in nicely with things like Loaders and ContentProviders.
I don't buy that analysis. In NYC, you don't need a medallion to operate a taxi - you only need one for a yellow taxi that can legally stop when hailed on the street. Having more medallion taxis just means that these taxis will take business away from the "black car" (reservation-driven) companies and from services like Uber (and those cars never park either - if they're not moving, they're not making money). Increasing the number of medallions won't magically increase the usage of taxis - the people who can afford them already use them, but for the vast majority of New Yorkers, the prices are way out of reach and they take public transit.

The syntax looks less than advanced.

Lisp has a lot pattern matching libraries and extension languages which are much more compact.
Cities vary. There are good cab drivers, bad ones, and really bad ones. I've had the same things happen to me as the previous poster: didn't show up, claimed credit card didn't work (frequent.)

I have also had a few other things: kidnapped, cab driver trying to run other cars off the road, talking on cell phone (40% - 60% of the time), stopping for gas, picking up their friends, operate a vehicle with brakes that were clearly barely operable, and so on.

Uber has bad drivers too, but I assume they don't last long. In NYC, at least, cab drivers can expect to keep driving even after killing pedestrians. http://nypost.com/2014/02/09/cabbies-who-kill-or-maim-in-nyc...
Singapore has a quota system for vehicles. The cost of a 10-year vehicle license under their auction system can exceed the value of the vehicle:
https://en.wikipedia.org/wiki/Certificate_of_Entitlement

The situation isn't the same as your hypothetical situation though. The licenses aren't perpetual or (for the most part) transferable.

Incidentally, the traffic flows pretty well there.
Sounds like Singapore (vehicle registration/COE, not licenses, but essentially the same thing.)

Life isn't TV. Most cops never fire their gun. My neighbor growing up was a grizzled NYPD patrol sergeant. He said that he never pulled his gun on anyone, but he cracked a few heads in his time with a club. Nowadays, it's easier to shoot than to beat up people.
New York's rent stabilization isn't that bad, but it also doesn't have a major effect on rents, either for those who have it or those who don't. (Rent-stabilized apartments can go up by a few percent per year.) It's the 1947-era legacy rent control that is patently ridiculous.

Most people underestimate the harm of that program because they don't understand price elasticity. It's true that only ~1-2% of apartments are under that system. However, 1-2% supply destruction can actually double prices. (See: oil shocks.)

Another problem is that this country is run by scumbags and pussies who allow foreigners to own real estate (many countries don't). Now, I'm all for a reasonably open immigration policy, and letting foreigners live here is not the issue. (The people who move here to live here don't have a major effect on the rent, and are good for the country overall.) But the types of foreigners who buy U.S. real estate are usually corrupt officials who want a place to live if their own country brings them to trial. (In China, corruption is a death-penalty offense.) This is the real reason why Silicon Valley is so expensive: every fucking Communist Party scumbag in China and murdering Russian oligarch and Arab slave state billionaire has bought a place (even if it goes uninhabited) in California. It doesn't affect a large number of houses, strictly speaking, but it's enough of a margin to have massive impacts on the price level.

I am amazed at Americans' willingness to be "patriotic" about stupid things and get into nonsensical wars... but then we go and let corrupt, murdering dictators and billionaires from all over the world buy California and Manhattan real estate. It's fucking disgusting.

For a while, I've been thinking about doing exactly this sort of analysis. Thanks for putting in the effort!

Does anyone have experience getting a feed of the raw NWS forecast data for many points in a large region (e.g. a state or the whole country)? I was thinking the other day that it would be great to have a web site that showed the forecasted chance of precipitation across a region, to answer questions like "Where in the Colorado high country should I go camping this weekend?"
This curve is not enough to evaluate the value of a weather forecasting service: if it rains, say 30% of the days in a specific area, you could forecast a 30% chance of rain every day and have good "accuracy". And yet that would be of no practical value.

I think a better metric would probably be something from information theory like mutual information, but I'm not sure which one exactly.
Where do you stop? I am sure we can point to any service/industry and find enough "reasons" to regulate it.

Did you know in many cities you cannot be a tour guide without a license? Open a hair salon? Want to do business with a government agency, well there might be rules pertaining to the services your business provides in that case, and that case only.

The list goes on and on. Eventually we need to really analyze what really is important. I would say if life is on the line then you might be justified, but driving a few people between points on a map?
Singapore is a different case, because it's such a small country. Between the size of the island and the climate (hot/humid) they can't afford uncontrolled growth of car usage. It's also a place (like Manhattan) where you don't need a car.

Frankly, I think car usage should, ideally, cost 2-3 times what it costs in the U.S. to account for all the externalized costs. (Those taxes could be used to modernize the train system and public transportation.) That wouldn't be practical, unfortunately, as the country is set up now.

Hogwash. If you are talking about SOURCE portability, Java runs in just as many places as C code, including in the embedded world.

If you are talking about BINARY portability (which is what everyone was actually talking about), then native code isn't portable for shit, whereas Dalvik code happily runs on multiple flavors of ARM, MIPS, and x86 with official or partially-official support.

Unless you are proposing that Android adopts a Goobuntu design of "compile everything from source", then the portability of native code source is utterly irrelevant. And if you are proposing that, you are hopelessly naive. Not to mention you must really, really hate having battery life if you want to spend over an hour compiling & installing, say, Firefox.
>I'd say if there is a distortion or limiting arrangement, it's not a free market,

Then the term "free market" is an oxymoron. By conjuring a market, which deals with money, property, and profit therein, you have already made it unfree.

Great article Colin. Unfortunately, I read it quickly since I need
to get going, but I'll reread it again when I get home.

I did notice a small typo here: "Fil lI nTh eGaps"
I think that's a very underestimated reason for why taxis and Uber alike are hated by many. There is an artificial medallion shortage, sure, but I'm in the same bucket as skosuri and think that code enforcement would solve a lot of problems. I think that even forcing Uber et al to participate in some of the codes - or creating new ones for rideshare services - would be great. Stuff like working with local paratransit services, 24/7 availability with decent coverage, choices that are more like "I have a wheelchair/need a ramp or lots of luggage" vs luxury or not (uber SUVs are occasionally super hard to come by!) and a standardized, routinely enforced safety program for vehicles and drivers alike.

Then the argument for overhauling taxi medallions and restrictive rideshare laws wouldn't be sidelined so often by stories of shitty uber drivers/practices and bad taxis alike. I also feel that everyone would benefit from this kind of government regulation _if done well_, because if left alone with little enforcement and only free market choices to influence business decisions, nobody would want to deal with servicing half of San Francisco, or folks with disabilities. Like your story of getting to SJC from Fremont - have you tried to catch an Uber on the east side of the Bay Area when you're not in downtown Oakland or near airports? It takes forever and a half even during the day. It's easier to just walk/use AC Transit to a BART station or wait and call for a regular cab five times than it is to wait for an Uber from OAK or worse for me, even though there were a whole bunch of times where I _wanted_ to pay for an Uber from Hayward to SF multiple times in a week (read: BART strike).
The tone was, I admit it, meant to be harsh. The reason for that is precisely because the high-income techno-libertarians feel entitled to be blithe about it. There's something irritatingly privileged about ideologies with lots of money behind them, that by some wondrous magic they are allowed to utter assertions where others (with less money them) are required to set out extensive proofs, and the most unpopular (who have basically no money) are required to display conclusive empirical evidence.
Chicago. :) The Lyft scenario was definitely cringeworthy. The lean startup questions outside the cafe weren't. I think it was good hustle and effort. They weren't pushy at all and handled "no, need to get baby back home" very well. They could probably change a few things to get a better reply rate on the street, and I wanted to help, it was just bad timing.
Isn't that roughly the demoscene, where there are often categories for entries that fit in 4kB or 64kB; or competitions to do the most interesting thing in 1kB of JS, or the like? Code golf?
If you use your own car as a taxi, your depreciation, insurance and maintenance costs would also be significant.

> Well Steve Jobs introduced fonts to computer.

What? First of all, I think that you're confusing typefaces and fonts. A computer font is computer code that describes how the size and shape, orientation, etc. of a collection of glyphs should be output onto the screen. Computers had successfully output text to a screen for decades before the Macintosh.

The Xerox Star, which came out in 1981, three years before the Apple Macintosh, had sans-serif and serif typefaces:

http://www.digibarn.com/collections/screenshots/xerox-star-8...

The Macintosh might have been the first popular commercially available machine that offered several computer fonts, but Jobs certainly did not come up with the idea.

What is your business? At €20K per month you must be close to or in the top 5 bitcoin merchants in the world.

>The cost .... $30 USD!

All you've done is move the fees to the customer side through their cost of acquisition and the spread bitpay adds to your charges.

>Fraud rate? 0%
>Chargeback rate? 0%

This doesn't matter until you stop accepting credit cards completely.

Also no denying bitcoin has benefits for merchants. The problem is the complete lack of benefits for customers.
Well, the finds range from 9000 years to 1200 years old, so that not only suggests these areas might have been previously habitable as recently as 1200 years but also that these areas were habitable for almost 10,000 years before becoming uninhabitable. Could it suggest a cyclic pattern? And, perhaps we are acting as catalysts to climate change with our greenhouse gas emissions?
Actually, if you are willing to stack, analyze, evaluate creditworthiness, account for, and collect from several dozen DSPs and ad networks, you really can replicate and improve upon the AdSense offering. Very few instantiations of this strategy -- including the one of which I am founder -- allow open access to the service, though. At mass scale, fraud becomes the limiting factor. But any legitimate site doing 500K pageviews/mo needs to be thinking ahead.

Better libraries express their dependencies in a pluggable way, which makes them more testable as well as composable.

The top-level application is usually a composition of libraries.

So in practice, I'm sanguine about apparently transitive dependencies. I prefer when exceptions from one library's plugged-in dependency flow through unmolested, as I see the libraries as mostly a flat dependency of the larger application. If you pull in dependencies transitively without paying much attention to them, you're sowing seeds for trouble with versioning, security scope, risk of stale projects if they're open source, etc.

I think of this as a corollary of Spolsky's law of Leaky Abstractions. Passing through exceptions means not trying to fool anyone into thinking they can work with the high-level abstraction without understanding anything about what's going on underneath.

Ideally the standard library provides base classes that act as core categories for different kinds of exceptions - IO, programmer error, data format error, etc. - so that general code can be written after a fashion when necessary. But I think you're fooling yourself if you think that such general code can be written the majority of the time, much less all the time. What's underneath always leaks through, one way or another, and if you try to ignore the thing that's underneath, you'll end up with brittle inefficient code.

Where high-level wrapping exceptions are justified is where there is an obvious chokepoint in the design - where the interface between several layers is very narrow. But this typically is at the junction between a service and a client - e.g. a web front end and back end, or async job queuing service, etc. - something where there is a service loop and probably service-specific logging of original exceptions, anyway.
What do you think native means?
The courts seem to be concerned with the results of hiring criteria, not simply whether they're intentionally discriminatory. For example, there was a ruling that a written employment exam for a fire department that disproportionately more white people than minority people passed was illegal discrimination, since it had no particular relevance to the candidate's ability to be a good firefighter. (On the other hand, a test to see whether you could carry an average-weight person out of a burning building would be OK, even if it excluded most women, since it was job-related.) Similarly, a candidate's willingness to drink has no relevance to their ability to be a good developer.
I started to get sick on one of my last Uber rides because the driver had on an absurd amount of cologne. Another had no clue what he was doing and explicitly took the street he was told not to take, getting stuck in the traffic I was hoping to avoid. Some of them are really reckless about driving too, sometimes ignoring posted signs altogether, and I think the only saving grace is that the cars are usually brand new.

I could go on about how much I have a problem with Uber, just like how much I hate taxis. The only nice thing about Uber here is that there's an easy way to get in touch and fix a problem. That for sure, I agree, is worth the cost.

That being said, I've found UberX in SF is cheaper than cabs, so I have even less interest in taking cabs.... but the last few cities I went to like NYC and Miami, the cabs were great. Wish SFMTA would step it up...

Anyone else find the graph of medallion values a little weird?

Looking at the DJIA, It was ~11,700 in Jan 2000 and by March 2009 it was down to ~6,600. The graph makes it look like it was about 100% of what it was in 2000. That makes no sense.

Also, they have the CPI plotted, but it's a straight line at 100. So they might be correcting for CPI, but in that case, you'd expect the 2009 DJIA to be even lower.

I think what Microberto is suggesting is to post a smaller unit of work and evaluate the results before committing to a freelancer for the long term. So maybe you put out a 15-30 hour job for $500-1000 to see if that person will work out. If it works out well, move on to the longer engagement. If it goes poorly then you're only out of $1000 and a week of time.
It's possible that you could create another syntax. But there are some challenges to deal with:

1) The presence of macros. I can extend the language with new syntax however I please. If you just write a parser, the minute I do so, it's going to be very difficult for that parser to determine the order of operations. It has to have some general solution to the problem of precedence.

2) It... I suspect... has to be homoiconic. That is the underlying datastructure that the code corresponds to has to be immediately visible to the human coding. When you write programs that manipulate programs, the lack of this ability cripples you.

If new programmers learn ... what I suppose you might call a cleaner syntax ... and then have to switch into sexpressions to see what's going on, I don't much rate their chances of learning Macros - they'd essentially be learning a new language when they got to the point where they'd want to do that.

3) It has to be mappable - and preferably in a reverse compatible way - to, if not all, the vast majority of existing Lisp code, (otherwise people who are already comfortable with Lisp code won't have much incentive to use it.)

#

I'm not going to say that's not possible. What I will say is that a fair number of people, who I don't think are idiots, have tried to update Lisp syntax in the past. Among others attempts RLisp, Dylan, and IACL2. I'm not aware of any project that's managed to maintain the ability of Lisp to clearly manipulate programs as data and to swap back and forth between interpreted and non-interpreted code.

But it's possible they just couldn't see the problem as clearly as we could because they couldn't see that the approaches they tried were going to fail. If you can think of a syntax that solves things, I'd read up on past attempts to see if someone's tried it before and then give it a go. Writing your own reader can be a bit of a pain, but it's probably more doable in Lisp than any other language I can think of. :)

Do you have any evidence to back-up the claim that foreigners are driving up the cost of property? I can't find the source now, but from the data I've seen, foreign purchases amount to less than 10%. What really drives up housing pricing in the bay area is speculation where contractors purchases homes for cash and flip them.

The other thing to think about is, do you really think "communists from china" are buying 1-bedroom apartments in the Mission? No, they are buying the multi-million dollar homes in Russian Hill. For the average American those homes were never within budget.
Bug filed, btw, response received, it's probably going to be replaced with a better implementation.
