just for kicks I decoded the QR code in the middle of the video, hoping for an easter(or rather xmas) egg, but alas only the rather boring http://web.mit.edu/newsoffice/


How fast can average QR decoders using a phone camera work? Would they decode the QR code from the playing video, or would you have to pause it? Just curious.


I had to screencap the video (their play button covers the video when paused). The QRReader app on iPhone wasn't fast enough to scan it during the video.


Hah. I was wondering about that. thanks!


Ugh. I did the same and was also very disappointed.


black on white, +flux.app


heh, that's me! was wondering where those HN hits were coming from... thanks for dropping by.


I once had an app rejected as it was "not amusing" (it was a "Unicorn Chaser" app). I also have had apps rejected for putting "iPad" in the wrong section of the name. For example "X for iPad" is fine, but "iPad X" is not.


awesome, I'm reading Applied Cryptography and this will be a good supplement. The MIT OCW course doesn't have a lot of resources http://ocw.mit.edu/courses/electrical-engineering-and-comput...

Does anyone know from the AI course the quality of the lectures & videos?


Applied Cryptography, no matter what Matthew Green may have to say about it, is a terrible book to learn cryptography from. I highly recommend you burn it and instead pick up a copy of Practical Cryptography (or Cryptography Engineering, which is the exact same book).

The mark of a good book on a security topic is, you can read it "upside down" and learn how to break things instead of build them.


Frustratingly, there's more than one applied cryptography. There's (obviously) Schneier's book, and then there's this:

(http://www.cacr.math.uwaterloo.ca/hac/)


Menezes is "Handbook Of Applied Cryptography", but this was actually a sore point with Schneier back in '98 (I feel like I listened to him complain about it in a bar at Usenix Security).

In any case, get Practical Cryptography.


Why is Applied Cryptography a terrible book?



More specifically, the one comment in that search that provides rationale: http://news.ycombinator.com/item?id=377187


I disagree that it's the only comment with a rationale, but it's a fine example. Writing the same thing about the same subjects over and over again is tiresome, isn't it?

(Thank you for taking the time to pick one out though).



The AI class is ok, but the lack of programming assignment really impede learning. On the other hand the ML class is great, even the web site is better.


It depresses me to see BBN Technologies referred to as Raytheon. Although they were acquired, it's as if Bell Labs were referred to as Lucent or Alcatel.


The current Bell Labs is a spin off of only the US Government contracts that were in place when the Lucent-Alcatel merger occurred. This was done because Alcatel is a foreign owned company and cannot be a part of sensitive government contract. All of the other research was kept with Lucent-Alcatel. So what's now known as Bell Labs is really just a name.

Lucent-Alcatel disbanded all research in 2008.


I hadn't heard of the spinoff; thanks. I worked at both Lucent Bell Labs (pre-Alcatel) and BBN (pre-Raytheon). I definitely keep track of BBN, it's an amazing company and I hope it continues to have it's own identity under Raytheon. Lucent Bell Labs was already dying when I was there back in 2003–but even then had some great active projects and Unix gods still around. So yea, perhaps the real "Bell Labs" is now AT&T Labs or perhaps Bell Labs is really dead.


this is where Google Labs went when it was "cut"


not sure if you're being serious, but no, google labs was a bunch of experimental projects run by normal google software engineers. this is an entirely separate thing.


partially a joke and partially just hopeful, yes. to explain myself, Google seems to have attempted to appease investors by focusing on their core money making products, while still maintaining their commitment to innovation with spinoffs like this. so it's the best of both worlds for Google and for us in this case. now if we could only find Google Code Search, Google Labs, and the old design of Google Reader somewhere in there too....


Echo this, recently a friend had an epileptic seizure in Switzerland and they not only wouldn't come right away, they made me very carefully justify why I thought they should come. It's my new rule not to assume this...


Good for them. Epileptic seizures aren't usually life-threatening.


Sorry-we had no idea of that not being professionals and she was blue and seemed not to be breathing. It turned out to be OK after the fact but at the time....


No. They can be. The probability is low, but during the Epilepsy the patient can injure himself.


Quite true. There are all sorts of pointy and/or hard things around that you don't notice until someone is having a seizure.


Two apps Circle of 6 and On Watch just won a government challenge put forth by VP Biden. The apps will be available in January, On Watch is similar to this product http://www.whitehouse.gov/blog/2011/11/02/announcing-winners... (FD: I'm the developer of Circle of 6)


I've used SimpleGeo since I met Joe Stump at Foo Camp. I was talking about my early stage iPhone app, Kliq which needed reverse geo coding and a few other basic location features. He suggested SimpleGeo and I got started quickly–though each of the features I used I was ready to rebuild on my own when the time came, rather than pay the as-then rather large monthly fee were I to be so lucky to have so many users.

It's been bumpy, even with relying on them scantly–I had hoped the feature set would grow and mature to take even more work off of my hands. Instead–several times the API changed from under me without warning or backwards compatibility and my alpha app simply broke. Once, embarrassingly in an investor presentation, another time it took a personal tweet to the founders to get things re-sorted out.

I'm sad that for so much money, such a great team, excellent visual design, hot shot investors etc. they didn't take off. I wonder if they just didn't hit on the right business model–for me it seemed I am something of a YCombinator gamble for them: they want my startup Kliq to be reliant on their services such that I can't or don't want to rebuild at scale (wasn't the case), price such that they take money from me Kliq now, as small developer team with little time to build cookie features not core to my app (they didn't charge us a monthly fee until the very very end, while we probably would have paid $5-$20 a month right away and up to $50 with more features), and price such that they "exit" with Kliq if we do end up scaling. Then they just need some success stories and they would have been too. Some ideas as a now former "customer".
