I don't think there's anything wrong with being negative per se. I work at Google, and can think of a couple of developers who complain about others' products a lot. And they can usually get away with it, and in fact even be popular simply because they're helpfully negative.

What's wrong is when someone is unhelpfully negative. This is the person who just complains no matter what happens.
You can achieve no delay without using a zero delay. Graphic Control Extension blocks may be omitted between images and so multiple images can come in a row without anything defining a delay between them.

See the last instance of the phrase "graphic control" in the document to see that multiple images can come with no intervening GCE blocks and see the paragraph containing the 5th instance of that phrase to observe that a GCE block only affects the first image following the GCE.

I wonder how that cap-and-trade system would be gamed by different interests?

The city would have to zone for the growth, or trade for credits. But zoning isn't the same as construction. It's hard to imagine an alternative without putting the city in the construction business, but it opens up loopholes. The existing system of "housing elements" http://www.hcd.ca.gov/hpd/hrc/plan/he/ seems broadly similar, and leads to some strange planning decisions.

So what evidence is there that the US condoned Fikre's torture? The alleged statement of a torturer? That doesn't seem very reliable. He couldn't prove his story in Sweden, so how will he prove it in the US?

Isn't it possible that the UAE came to find out that Fikre had some involvement with the FBI over the Portland mosque, wanted to know why, and decided on torture on their own? Maybe they suspected that he had been turned into an FBI informant.

It seems a bit far-fetched that the US would be outsourcing the torture of suspected Muslim terrorists to a largely Islamic country, and just waiting for suspects to travel there so that it can happen. And the State Department's statement that they saw Fikre and he seemed ok seems strange if they had anything to hide.

You've got it backwards about the role of oxygen--it is being used to inhibit polymerization in this case. They are allowing oxygen to dissolve into a thin layer at the bottom of the vat so that the build doesn't stick to the membrane, and they can have a continuous draw.

The true build layer is actually within the liquid, near the bottom, but not on it.

Methane is lower cost than other raw materials like oil. That is why there is an opportunity to make chemicals cheaper, and also greener. The microbe itself it the catalyst - actually the enzymes inside do the work.

I think we're at cross-purposes to some extent. The paper isn't claiming the article is unique [in being Afghan silver jewellery in Sweden] as it clearly mentions not only other silver coins but other rings (IIRC) having come to Sweden from "the Caliphate". The specific details of the physical appearance of the ring they are claiming indicate that this item has a unique story; I challenge that claim being entirely supported by the evidence they presented (see my other comments).
First, renting is supposed to be an option for mobile people. Renters' mobility is more important than homeowners' mobility, who have self-selected to be somewhere for a while.

Second, rent control generally makes you more and more stuck each month. Selling your home and buying a new one is a one-time hit, and if there is sufficient motivation, it will happen after a while (technically, brokers' fees increase with the home value, but they are 6% or less, so doubling the broker's fee is a lot more palatable than doubling your rent).

Third, home ownership offers other options, like renting it out, if Prop 13 keeps you stuck with the house.

Fourth, home ownership is not subject to the tension between a tenant and a landlord who doesn't want them there.
Because it's not obvious. Do you dispute the article about jaywalking?

Yes, the so called "vertical response time" is still a factor to be considered, though I'd argue this stage is on equal footing as in the case of actual paramedics, assuming the Uber drivers are given a clear mandate to enter the environment in these scenarios.

Regarding your point about whether drivers could really become qualified, I see no reason why not. CPR/AED training exists for a reason, and it has saved many lives. There is also precedent of providing emergency AEDs for civilians to operate in these life or death cases. See the typical high school gym, which will likely sport an AED. Perhaps it wouldn't be every driver's cup of tea, but I can see many drivers sign up if well-designed incentives are put in place.

Will drivers confuse symptoms of SCA with stroke? That's why they would be required to go through AHA's training course.
You're right that AEDs can cost around $1000. Consider this in the context of how cars cost many times more than this amount. Further, the cost can be subsidized by Uber, as Uber stands to benefit financially when they save someone's life.

I agree with you that there is a lot of leg work required to make the further optimization of emergency lights/sirens. That would be something that comes later, and perhaps not necessary given that the median wait time is already under 3.5 minutes.
I think Internet comments encourage this behavior but it has always existed and isn't unique to programmers. Just today I read a long reddit thread with military people arguing about aircraft.

By San Francisco, I suspect they mean the San Francisco Bay area. While building in SF proper would decrease rents there, we can't have everyone who wants to move to the Bay Area live in San Francisco proper.

Keeping this in mind, SF proper has a natural and inherent economic rent. So there is only so much pressure more building could relieve in SF proper. That said, I don't think many people would have much issue with being able to afford a place in San Mateo, Mountain View or San Jose, even Fremont. The problem is the whole bay area is averse to build up. So the only current option for those not able to afford the housing, is to commute two hours each way --South from Gilroy, East from Livermore/Tracy, northeast Coco county, etc. or doubling, tripling up and sharing rent. But that's not an option for many families.

It'd be physically difficult to have more than 6 million people living in San Francisco, no matter what density we built. So there would be some limit, just not the current approximate 800 odd thousand. The solution is to have an integrated Bay Area plan to accommodate as many people as the area can support. We must also keep in mind the ecological impact of sustaining more people in a semi arid region so perhaps desalination plants to offset water demand. Most of all, a regional government capable of making hard decisions rather than one which gives in to boisterous interest groups (rent control, height & shade restrictions, prop 13, and the adversity to pubic transit.

> Why does it have to be fair to the landlord?

Well, it doesn't have to be.

But prospective landlords tend not to build new units (or maintain old ones) when they don't feel they are getting a fair deal. It leads directly to the situation they have in San Francisco, where property owners only rent to family, coalesce many smaller units in to few larger ones and sometimes withdraw their units from the market entirely.

Landlords are investing capital and their own labor in their properties. If the expected return on that investment is less than what they could get from government bonds and a 9-5 job, don't plan on a big expansion in housing stock.

Ask HN: Private Photo Sharing Service
Hey Guys,
I'm thinking about building a private photo storage & sharing service. The concept is very simple: store your photos on the cloud and share privately with the people you know.

Photos could be shared by email or directly with users (Unshare anytime. Shared by email is a link which opens up the page).

There's also a concept of 'Groups', i.e., a picture can be shared with both "Family" and "Co-workers" groups.

Through the app, photos could be pushed to Instagram, etc. so that you always retain original in one spot.

What do you guys think of the idea? We have already built a platform that we could use to finish this app/service in less than a month.

Thank you.
MIT alum from the early 00s here. MIT was a stressful place. Much of that stress was self-imposed, and in an environment full of ambitious, intensively competitive over achievers, it can start to create a negative vibe. Turns out, this was good preparation for real life in the competitive fields that many of us chose.

The MIT administration at that time, to their credit, let students do pretty much whatever they wanted - take time off, re-take failed classes, reschedule exams, get special accommodations when needed, whatever. If you asked for help, they helped you. Lots of career admin and support staff who would bend over backwards to make miracles happen. I have never before or since encountered a more supportive administrative environment and it's that experience that will endear me to the Institute forever.
We are grateful for our time at LS9, we got to work with some amazing people. I learned:

It's important to be flexible. Having the ability to use multiple raw materials and make different products is important, especially when the prices of all those things is constantly changing (think oil today).

Most people won't pay more for a green product. But if you can lower the cost for something that's already environmentally friendly, you can make an impact.

When it comes to living cells, we don't understand as much as we think we do. That means you need to try both engineering and evolutionary (random) strategies.

Thanks for the good wishes!
"Rent control is a subsidy to renters paid by landlords"

I'd expand on this: Rent control is a subsidy to current residents, paid by future residents. The landlord is merely a conduit across which the wealth transfer flows.

Roads are great. The argument is against personal cars. You can have most of those gains with a vastly smaller number of automobiles, and remove many of the negatives like parking lots.
I couldn't believe that the new 49ers stadium (in Santa Clara) cost a trillion dollars, so I looked it up. It cost $1.2 billion [1] - a "gigabuck" rather than a "terabuck." To put that in perspective, a single office building in nearby Palo Alto just sold for $300 million. [2]

Judging from the people driving up and down 101 with flags flying, the people wearing 49ers jerseys year-round in San Jose, the big BBQs hanging off the big trucks in the parking lot of games, and the truck commercials that litter televised football, the new car-centric location suits the football team nicely.

I'd be much more upset if the SF Giants decided to move out of the city!

Bravo to the CEO for handling it this way. It really shows how treating others like humans and remaining compassionate no matter what the situation is beneficial to everyone.
The articles scenario assumes that the supply is elastic (and only bound by rent controls), while the demand is static, which is not even remotely plausible (e.g. see http://en.wikipedia.org/wiki/Urbanization - almost everyone wants to live in a city)

What would really happen is a massive influx of demand, because many people rich people (rich in this context: "Have the means to buy high-priced properties") who do not want an apartment today (because there are none which meet their 'standards', partly thanks to rent controls), would start to move in. This would lead to a situation where a) all new supply would be concretated in high-priced estate, which would still be bought up by the increased demand, while b) the bottom (i.e. todays rent controlled apartments, going with the assumption these are not well maintained and therefore 'cheap') would just go up in price, because there still wouldn't be any new options for the inhabitants of those properties. Result: Higher prices for the current occupants of apartments, a new crop of high-priced apartments bought up by rich people, no better supply of "main street" living room.

Mixed taps are all over the US and many other places in the world and have been for a while and we have no water safety issues from this. Water safety has nothing to do with it:

"Most bathroom sinks in Britain still have separate hot and cold taps today, 60 years after Mr. Churchill’s conversion and decades after nearly all dual taps were scrapped in the U.S. and most vanished from continental Europe. For reasons of thrift, regulations and a stubborn attachment to tradition, the British have resisted the tide of plumbing history. Even when they renovate old homes, many choose two-tap systems, and builders often install them in new, low-end housing. Separate taps account for an estimated 40% of all bathroom-faucet sales in the U.K."
