Will they fix the problem? Certainly not. Are they a step in the right direction? Almost certainly yes.

The main problem with cars I see is that they're inefficient as opposed to mass transport (as Rees seems to suggest in the first article). Additionally, by suggesting that they are the solution, this creates a false sense of security in people having "done their part" to save the planet. For example, if I recycle, that's good, but it hardly means I've eliminated my carbon footprint.

However, where I disagree is that I believe developing these technologies -- engines that can run more efficiently on electricity -- are inherently useful to us building a more sustainable future. If we're able to build electric tractors, boats, ambulances, ATVs, etc. built on top of this technology, then that is no doubt useful.
Why do you think that?

This technology seems not too bad at first - "each person appears as a single pixel indistinguishable" - but after thinking about this, it's really a big deal for three reasons.

First, it would be trivial to tie this in to the network of surveillance cameras, so you can see a person in detail when they walk past a camera. You're now not an anonymous pixel but HD video.

Second, by correlating the "pixels" with even coarse celltower location over time, you should be able to match a cellphone with every person. In other words, you now know their identity and track almost everyone's location to within a foot. No GPS needed.

Third, this information could be stored for all time and easily accessed.

I think this really is a "game-changing" technology as far as privacy goes. It ties together location, identity, and images very tightly in a way they haven't been connected before.

This is an interesting theory problem, but it might be clearer to talk about shooters at a firing range, separated by partitions such that they can each only talk to their neighbors. The barriers eliminates the trivial solution of the shout: "Fire on the count of 3!" that common sense would provide.

The simplest solution would be to establish a clock, because with a clock you can say "Fire at 1pm exactly!". But even this is interesting because it requires shooters to know where they are in the line in order to take into account any signal propogation delay. If each person takes 1s to repeat a message that they hear, then it takes n seconds to go down the line, and each shooter must know how to compensate for that delay. E.g. the first shooter hears "it's noon", the next shooter hears "it's noon" but knows that he's 1s away from the source, and can calculate that the time is actually 12:01, the next shooter knows it's 12:02 etc. They could synchronize clocks, specify a time "shoot at 1pm!" and get the job done.

But what if we take away their clocks? This is where my intuition fails me, because I don't see how the problem can be solved without clocks. If you don't have clocks, you need to somehow get a signal to every shooter simultaneously, which I think is theoretically impossible, since without a clock the shooter cannot execute instructions on their own.

Which probably means I don't fully understand the scenario :)
IMEI blocking hasn't stopped phone thefts in Europe.

Possible reasons:

1. IMEI numbers can be changed.

2. Thief can still use phone for many hours until block.

3. Stolen phones can be shipped to countries that don't implement block.

4. A blocked phone can still be used to run apps, play games, make VOIP calls on wifi etc.

The Apple system seems much more sensible. You can't use an iPhone without the pincode, and even if you get that the owner can remotely lock the phone as soon as you connect it to any network. The way to avoid that used to be to wipe the phone and reinstall the OS, but now you can't do that without the Apple ID and password of the owner. I don't know if this has reduced iPhone thefts, but unless the thief has an exploit in Apple's security I don't see why anyone would steal an iPhone nowadays. I wish Android would implement something similar.
Mt. Gox didn't say they were resuming withdrawals, only that they had an announcement to make. There will definitely be a market reaction based on what they say (or if they instead keep silent, it'll likely be perceived as negative).

Also note that Mt. Gox tends to trade at a 10-15% premium to other exchanges, since most fiat currencies take weeks if not months to withdraw. Right now it's like 3%, and overnight, it actually dropped BELOW some exchanges. It'll be interesting to see what happens when things get back to "normal". Will Mt. Gox's premium return? Will it return in the form of the market discounting other exchanges?

It's scary that such a poorly run operation (what they have right now is essentially a software bug, due to not accounting for a types of BTC transactions; but they've crashed due to volume and have been hacked, to say nothing of the actions taken against them) can influence the price so strongly.
Nice message at the end, but to be honest I don't think anyone bought the story in the first place.

But how? I can't see any realistic chance of a broad international agreement. Remember that it works both ways, too. What would you do if your phone stopped working because a telecoms company in (say) Nigeria accidentally asserted that your IMEI was stolen?

Saying "wouldn't it be great if the world could co-ordinate" is not the answer as it isn't realistic. It's avoiding the problem and the need to come up with practical solutions. Or even an honest "it can't be done" answer.
This and the fact that they can sell phones for a fortune (~retail price) in emergent markets, instead of local black market prices (30%) means robbers will organize shipping lots of phones overseas. That's what happens in France already.

Honestly the one interface should be the AWS API. Eucalyptus has already embraced it and set the tone. OpenStack is partially there but political battles in the community have forced a stalemate.

They are doing this all wrong.

Show HN: Visualize a users mouse movements
I lost my iphone some time back so when I called AT&T to report it, they kept on insisting me - please wait for few days as you may find it. They also told me once we report the phone as lost and block it using IMEI then this change can't be undone incase you find your phone then it can't be activated again. And, the block using IMEI does not work across carriers which means if its blocked in AT&T then the person carrying that lost phone can activate the phone on any other network like verizon, spring, t-mobile etc.

Carriers can maintain a centralised database to keep list of stolen phones and can also undo the change incase the owner finds it. They can also track the people who are calling using stolen phones but they dont do it. The best reason I can guess for not doing that is as you said - why they will do something which will hurt their own business

It must be nice to have no valuable skills to offer society yet still find employment as an authoritarian jackass dreaming up product features without doing the actual work or assuming any of the risk. If Leno wants to add features to cell phones, he should go work for those companies instead of using the Ring of Sauron to forcibly add a "kill switch" because he thought it was a good idea. And is reducing theft the real reason or just the ostensible one? Will this become an easy hook for govs to shut off phones?

I don't know -- that seems naive. This is not a new story.

From the Wikipedia entry on Guilds:
As Ogilvie (2004) shows, the guilds negatively affected quality, skills, and innovation. Through what economists now call "rent-seeking" they imposed deadweight losses on the economy. Ogilvie says they generated no demonstrable positive externalities and notes that industry began to flourish only after the guilds faded away. Guilds persisted over the centuries because they redistributed resources to politically powerful merchants. On the other hand, Ogilvie agrees, guilds created "social capital" of shared norms, common information, mutual sanctions, and collective political action. This social capital benefited guild members, even as it hurt outsiders.

The heyday of guilds lasted from around 1200 to 1700...

Tiny bills like these get proposed by legislators all the time. Most don't pass. Just because this is a technology bill doesn't mean that it will – it's far too nanny-state and superfluous control to be remotely considered vs other priorities California has at this time.

> But I don't see how it could happen since AFAIK the French privacy laws predate the Directive by a quite large amount.

And more importantly goes further than the directive in protecting citizen's rights. By comparison the french "garde à vue" — a form of police custody — is also ancient but it restricts citizen's defence rights far below the mandatory minimum and has gotten repeatedly hammered by the ECHR both indirectly (via similar turkic cases e.g. Salduz v Turkey and Dayanan v Turkey) and directly (e.g. Brusco v France, Vassis v France) as France (incorrectly) refused to consider the turkic cases applicable.
I appreciate the humility in this post. I have often had much the same reaction the author mentions - annoyance with some asshole's "obvious" suggestions after thinking about something for three minutes that other people think about for large portions of their lives. And of course you can always come up with ways to make a fundamental lack of humility and empathy sound anodyne ("well who knows, maybe they didn't think of it!"). Good post.
I am sure they power off the phones almost immediately. I actually don't think a legislative solution is the right process. I think Apple should address the problem for the benefit of their own customers. Maybe they need to investigate this and work with Interpol.
Most Facebook controversial posts aren't invitations for discussions, but biased rants.

Discussions almost never really take place. Most people don't know how to be objective.

You can make all of the arguments you want with every piece of evidence supporting it, yet most people are so entrenched in their way of thinking that they still refuse to really look at issues objectively. Even when slammed in the face with the truth, they'll generally find some weak straw man argument to still retreat to in order to maintain their biased point of view.

Gox had a huge gap in its price to other exchanges. This gap came to be because Gox replaced USD with Goxdollars (a kind of currency that only exists inside of Gox). Therefore arbitrage was not capable of closing this gap, because Goxdollars could not be converted to USD.

If you are trading Bitcoins for Goxdollars, that's fantasy trades.

However this novel introduction of Goxdollars was now consequently followed by the introduction of the Goxcoin which marks the migration complete. Goxcoins cannot be converted to Bitcoins. However you can now trade Goxcoins vs. Goxdollars.

All trades on Gox are now pure fantasy. Seeing as Gox is the Magic the gathering exchange, I find this strangely appropriate.

I gave up on the effectiveness of yearly performance reviews more than 20 years ago when I got a bad review for spending 20% of my time on internal company support instead of 10%. I had been sending my boss weekly reports all year and the week before my review he added up the time and decided my priorities were wrong. That review cost me more than 4K in bonuses and raises. Protesting to the VP made no difference.

When I resigned two days later the SVP got involved, gave me almost 10K in bonuses and raises and promoted me to a lead role on another team to keep me.

I've seen nothing but problems ever since; morale issues caused by disappointing raises and bonuses, problem employees left to fester until the review, a week or more of lost productivity as everybody fills in massive 360 surveys and then argues over them for.

Weekly 1-1 meetings with regular review checkpoints make far more sense.

Do you feel the documentation gets across what can be done with it clear enough?

For instance, This doesn't need a js dependency but you could easily mock progress using a keyframe animation on a particular progre(c)ss etc. I am going to try and make some clearer docs and try add some feature attributes, or classes.

I just want it to be clear to people that you can add it to existing elements I think without changing design.

Each exchange has its own circumstances that are reflected on the price. For example, it used to be difficult to get fiat into BTC-e, hence the price there was lower than the average (sell your BTC cheap now, or wait until someone wants to buy at the average price). To say that mtgox was manipulating the prices is an extraordinary claim and requires extraordinary proof, which you don't seem to have. A better explanation would be that they had problems with fiat withdrawals, probably due to ridiculous regulations and bureaucracy problems like the ones they suffered in the US, therefore the price was higher than the average (wait for your fiat, or get your expensive BTC today).
