A few problems in your comment:

1) The article text is wrong (and doesn't match the pics of the slides). The chip demonstrated today is Knights Corner which is a new part, not the older Knights Ferry SDV.

2) When counting flops we need to distinguish between single precision flops and double precision flops. You're comparison isn't valid -- Knights Corner was shown sustaining over 1TF on a double precision code. Nvidia's most recent flagship GPU has a theoretical peak of 515GF/s but sustains less than 225GF/s on the same DGEMM operation. Knights Corner is sustaining 4-5x that, and this implies that it's theoretical peak is higher again. AMD's GPUs also cannot touch this with a single chip. Their dual chip 6990 has what looks like the same theoretical peak but far lower practical performance due to being more of a graphics part than a compute part (e.g. look at the cache structures).

You are correct that these are real cores, each with a wide vector unit. If we wanted the equivalent of GPU "cores" we should multiply out by the vector width per core.
For the average access point user, changing the SSID is probably the least difficult option. It also has the useful feature that it actually indicates the owner is the one taking the opt-out action, rather than someone else who can wardrive and opt-out access points for a region.

The HN crowd might skew a little different distribution in their technical ability to do things like identify a mac adddress.
There are two problems with the MAC approach:

1) The amount of Mac addresses for each vendor is very limited. Blacklisting a few Mac addresses would therefore blacklist lots of routers. Combining this with the SSID doesn't really help that much, as many users will stick to the default SSID. (And if you require that users change their SSID to a non-default one you can as well require that they just add a given suffix).

2) In the EU there have not only been complaints about Google offering the data, but also about Google processing the data. So I guess they want to make sure that their streetview cars that log this data don't log opt-opt routers at all. It's simple to do if the SSID has such a suffix. It'd be much harder if the software system in the card would need to query a central opt-out database before processing a router's data.
It'll probably make apps better if they know where every SSID is. I don't see this as a bad thing, although it is a minor privacy intrusion.

Nah, don't feel stupid. I've just been thinking about stuff like this, where basically you can let people get going anonymously, because in some instances people are going to want to save something. it just may turn out that scores on your game is one of them, so just like entering in one's initials in the arcade, you can ask for email.

Speaking as a European (albeit living in the US) this doesn't offend me at all. If you're broadcasting an AP, then it's like walking past your house and noticing what color it's painted. Don't want to broadcast, then plug in a wire. It's not like they're monitoring your traffic.

When I was growing up, every household with a telephone got a book that had everyone's name and home address in it. That too was an opt-out system and that approach worked pretty well.

That depends on whether you use the first 52 values after the seed as the shuffle or are allowed to produce multiple shuffles from the same seed. In the latter case it also depends on the, unspecified, period of the PRNG.

>The amount of Mac addresses for each vendor is very limited. Blacklisting a few Mac addresses would therefore blacklist lots of routers.

MAC addresses should be globally unique. If your hardware vendor is shipping lots of routers with a shared MAC, they've messed up really badly.
Everything he said can pretty much be said about the web, too. Along with that comes the fact that of these millions of news users, hardly anyone will want to pay a dime for anything.

That was the beautiful thing about developing software in the 90's: people were still willing to pay for stuff, you just had to figure out the (often insurmountable) distribution. Now, it seems like the only way to make a meaningful income is to insert yourself between layers of large business.
How insane is it that you have 12k karma, have no problem commenting on js, ruby, jquery, mongo or even css... but you're worried about people not understanding this bill.

period.
If you configure your AP to broadcast your SSID, you are advertising yourself to the rest of the world and you should expect the rest of the world, including Google, to catalog your existence.

If you disable your AP's SSID broadcast, then Google should not catalog your AP and if they do it by sniffing packets then I would say that's unethical.

But complaining about Google with SSID broadcast enabled is like hanging out in a singles bar after taking a vow of celibacy.

In the past (working at an ISP) I've seen collisions on Ethernet hardware (two Ethernet cards with the same MAC address). So if that even happens in a relatively small Ethernet, I assume that this will be fairly common if your address space includes each active WiFi router.
Opting out is simple: stop voluntarily broadcasting unique identifiers out unencrypted on the public airwaves.

This is like complaining that your neighbors keep posting naked pictures of you on the Internet because you like to sunbathe nude on your front lawn.

No. Google is not going above and beyond normal privacy protections outside the US.

Just because you can collect the data, doesn't mean you are allowed to. In countries with other definitions of privacy it can be considered a reasonable expectation the your AP's SSID is only visible to people within a small radius. The owners clearly didn't have the intention to have it collected by a major corporation, collated with other data about their location and then published world wide for entirely different purposes then for which the AP was set up.

In many countries, the law protects people against those kind of unintended consequences, and several European authorities have made it clear that they consider this kind of use an invasion of privacy. And that is considered more important than multinational giant's ability to offer an "effective" service.

You can argue the merits of this, but Google's stance of "just fucking opt-out then" is blatantly disrespectful.

Why only 57% of visitors to TPM are using Windows
A significant portion of the undergraduate population at my school receive scholarships that are recurring on the condition of maintaining a 3.0 GPA. We're talking non-trivial amounts, on the scale of $18-22k scholarship money per year for a school that costs ~$45k/year. For students receiving these scholarships, grades matter significantly, and it can become an economic question of whether they'd rather continue pursuing the engineering degree and graduate tens of thousands more in debt, or switch to an easier set of courses that will allow them to retain the scholarship.

I think a lot of it also has to do with expectations from parents. For a lot of students, graduating with an engineering degree and a 2.5 GPA will leave mom and dad less happy than an English degree with a 3.5 GPA, even though the former is more likely to be useful in the job hunt.
Noticing something as you walk by and a corporate giant collecting, collating and using that information for something the owner never intended it for are two wildly different things. Context is everything.

The phonebook was a well known consequence of having a phone, dating back to the days when the phone companies were state owned public services. These days it would be utterly unacceptable if for instance internet access providers would do the same thing. Again, context is everything.

And just to make it clear: as a European, you are not offended by an American company that thinks it has the right to ignore local laws and sensitivities?
For what it's worth, I've been involved in A/B testing this exact thing to hundreds of thousands of new casual game users. You might be surprised. I would highly recommend the OP test this theory. :)

The gold rush moniker is really apt when used to describe the app store. Mainly because only a few, very few ended up rich, while most did not. The people that made the most, were the ones providing for the miners, and again, Apple and people making tools for people to make apps are making a killing, while only a few app makers are making anything substantial.
tl;dr: In November only 56.81% of visitors to talkingpointsmemo.com were using Windows. Windows is losing ground to OSX but mostly to mobile.

It would be interesting to compare this to other sites. I'm sure there's a demographic that's influencing things on TPM.
16-bit Intel 8088 chip by Charles Bukowski
> I would suggest that Google have intentionally created a high-friction solution of "-nomap" to your SSID simply to make it as difficult and unpalatable as possible.

A serendipitous example of the difficulty of Google's opt-out "solution" is that the correct SSID suffix is "_nomap", not "-nomap"! The Icrontic article is incorrect. I would hope Google forgivingly matches any "*nomap" SSID.

When it comes to privacy violations in the digital age, this is so far down the list of concerns that I don't understand why we're talking about it. Probably just because some politicians in (I believe it was) Germany misunderstood what it is and took legal action against Google.

Facebook / other social networks, poorly secured databases, warrantless GPS tracking (in the U.S.), cell phone data being stored; these are all orders of magnitude more worrying and more likely to cause harm.

Big discount at Harmony Hotel in the central of Hanoi Old Quarter, Vietnam
As someone who just moved from Portland OR to the Bay Area in order to take a "corporate" engineering job in SF (and got a >40% raise in the process) I can say with confidence that the cost of living here, even outside the city (specifically Berkeley for me) is easily 2.5x what is was back in PDX, even with a 60 minute commute and meals comped at the office.

It's not just housing (which costs easily 2x what it does in or near any 2nd-tier tech city) - transportation, food, and mundane but pleasant things like pints of microbrew and movie tickets are way more expensive, too.
I'm just curious (and hope I don't come off as being ignorant), but what kind of exciting theoretical CS developments have occurred in the last few years? If you can list some really groundbreaking papers that aren't too advanced, I'd love to read them.

A lot of us are actually using "virtual credit cards". They are like debit cards tied to a secondary account. You transfer money to said secondary account through the bank's webpage and then the credit-but-it's-actually-debit card is used to draw directly from it. This way, when you give your "credit" card online, even if it gets stolen, your main account is left unaffected.
If someone has gone out of their way to disable SSID broadcasting, that seems like a pretty strong message that they would like to opt-out of Google's Wi-Fi trawling.
I see questions about why this is better than a GPU for anything. Two main things:

1. The double-precision floating point performance is a lot better.

2. Unlike GPUs which have baroque memory access restrictions and many performance cliffs, this is a much more familiar SMP architecture with a unified coherent cache hierarchy.
I don't know why your comment is being down voted. It's perfectly okay for people on Hacker News to be expected to add "_nomap" to the SSID but for most people, they just won't even be aware that Google's collecting this data, let alone figure out how to opt-out.

I love Google as a company but it seems that more and more of it seems to be getting shrouded behind lawyer speak. It makes me uncomfortable.

India: The World's Secret Silicon Valley
Ahhh...got it. Thanks for clarifying that.
Let's say you walk down the street and every block, you look at your iPhone and see what wireless base stations are available. Say on a certain corner, you see "Linksys", "Free_Porn", "Mom's Wifi". You write that down in your notebook.

You do this block by block for an entire city. So now you hold in your hands a notebook of all the WIFIs in the city. So let's say I blindfold you and throw you in a random street corner in the city. Using this notebook, your iPhone, and the wifi signals, you can easily figure out where you are in the city.

To be even more accurate, you may record the signal levels every 5 feet. So now from any given point, you can say "Linksys" has 5 bars, "Free_Porn" has 2 bars, and "Mom's Wifi" has 3 bars... I must be at the south east corner of 59th st.

So now you have a notebook of all these wifi signals. Your friend comes to visit your city and you give him a copy of your notebook. He can then use that to figure out where he is even if he can't get a GPS signal.

What's also nice about this is that it works indoors. Using a database of wifi signals, you can figure out that you're standing next to the kitchen in your 5th floor office.

That's basically what this wifi mapping is.

While Jobs didn't have any direct control over the biography, he did spend hundreds of hours with Isaacson and certainly would have mentioned things that he would have wanted in the book, technical and otherwise; and Isaacson certainly would have included more technical details if Jobs had mentioned them over and again during interviews.

The fact of the matter is, though, that the nitty-gritty technical details are just not part of the picture for Jobs. Jobs picked at tiny details only when designers and engineers did something wrong or did something didn't lend itself to Jobs' greater artistic vision. If you're interested in exceptional technical detail, Jobs just would not have been your man.

And let's face it, if you're interested in the technology. there will be dozens of engineers and a limitless number of other writers that can write about those matters later. Gross technical detail is just not seeing the forest for the trees; and if you don't realize that fact, then you are someone that would have probably have been met with Jobs' scorn.
They're basically the same thing with different ranges. NFC has a range of about 4cm, RFID goes up to a couple of metres I think. NFC is generally used when you want to make sure someone gets really close, which is generally the case with payments. You don't want someone able to interact with your credit card from several metres away without you knowing about it.

I was sad to see that Gruber couldn't step out of his Apple bubble to tackle this topic (or any topic, ever), so I will:

Everyone who thinks "I should be developing for platform X" is thinking far too small. Take a look around you.. how many of the great companies were formed developing for a particular platform (unless it's their own)? Almost none. In 10 years, do you want to be the old and busted equivalent of the MFC expert whose software was hot in year 2000?

You don't make the Googles, Facebooks, Twitters, of the world by developing just for iOS. Or just for Android. If that's your business plan, tear it up and start over. Because $0.99 a pop doesn't amount to jack-all unless you're Angry Birds. And even they, if they got $1 for each of their 500MM downloads, have still not made as much as Modern Warfare 3 made last week ($738MM in revenue).

Go create a market. Stop being part of Apple's/Google's market for drumming up hardware sales and/or serving ads.

Oh, I agree it's way down the list.

But this attitude is exactly what I mean: nobody misunderstood anything. Really. Just because people have different values and priorities doesn't mean that they are too stupid to understand the issues. It certainly doesn't mean their laws can simply be ignored if you do business in their country.

Anyway, I'm going to stop arguing that point, since apparently this place is turning into Reddit, and downvotes our now used just to bury other opinions.
I would actually like the opposite feature from Google: let me update my location in your DB! The last time I moved house, it was months before before my phone started locating me correctly when at home. Of course, the hard problem in doing this is to figure out ways to avoid contamination of the DB.
When people talk about NFC, most people seem to be talking about only payments. The article talks about other uses as well for NFC. To me, NFC is a bridge between the real world and the virtual world. I look at an NFC tag on an object or a physical entity as really a door that leads to its digital manifestation in the virtual world. Some things are done better (or can only be done) in the real world and some are done better in the virtual world. For example, walking into a store to take a look at the product and try it out for yourself has to be done in the real world! However, finding out what others think about it or it's pricing history is better done online. What NFC does is marry the two worlds seamlessly. Where previously the user had to do this manually on his phone while at the store, a scan of the NFC tag could readily bring up all the relevant information. Bar codes and QR codes make this possible as well - so I cannot quite answer yet why NFC tags would be better for this. But there are other cases of active-active interactions (as opposed to active-passive interactions) where a passive bar code or QR code wouldn't be enough. A good example of this is authenticating someone in person where authentication relies on both the physical proximity (which is established with an NFC scan) and a crypto protocol to establish the identity that is best handled by your mobile device. Mobile payments happens to be one use-case of the active-active interaction where physical proximity is transformed to an interaction in the virtual world. Admittedly the biggest use-case though.
