[replacing a somewhat rambling and distracted response with a "never mind..."

...Or not; it appears my edit to this overlapped a response, so I'm putting my rambling comment back, below]

----

Checking now, it looks as if, as of today at least, Facebook is also using/preferring AES_128_GCM. Again, I don't have a specific note-to-self to refer to, and my memory's a bit fuzzy, but I seem to recall that until recently they were using AES_128_CBC, or something else other than GCM.

If you've time to answer, are you familiar with this use and change (am I right, specifically?) and if so might I impose for a sentence or two on what improvement the change to GCM brings?

Regardless, thanks for the description and qualification in your parent comment.

P.S. Upon reflection, I think I recall Facebook using AES_128_GCM for some time now, although I seem to recall -- perhaps incorrectly -- their using something else at some point after they switched to ECDHE_RSA.

I mostly look at the certificate chains as a check against obvious man in the middle situations. Again, I'm not claiming any kind of expertise, but I do have a certain degree of curiosity.

P.P.S. So maybe I shouldn't have asked/imposed my follow-up. Or maybe a better question would be, how is Facebook doing / regarded with respect to this aspect of security, these days?
You should change the title - the content is interesting enough that you don't need the mystery, and many people who would otherwise be interested probably won't click.

Cool stuff though!
The ~97% of comments that are "nice idea but..." is probably not far off the percentage of nice ideas discussed on her whose implementations don't quite work out :)
US Senator Jerry Moran is hearing from Reddit before Bitcoin hearing
Bitcoin's volatility seems to be entirely a function of demand. People buy it because the price is going up. People sell it because they want to take profits or are scared the price is dropping.

You'd be crazy to use it right now for legal goods and services. The view of many Bitcoin critics (including myself) that it's horrible as a currency but a massive success as an investment vehicle seems stronger than ever.

Likelihood of cancer may be related to the general chance of reproductive mutation, and the chance of reproductive mutation is also likely to be something that changes through evolution.

If you have a species in a high-radiation environment, is it not possible that it evolves to have fewer reproductive mutations in general - and therefore lower chance of cancer?
I would like to know how they break out of sandbox and actually access physical radio on iOS without jailbreak. Because you know, it is not like Apple would like to patch that asap.
How long did you stick with it? It cycles through the same few channels at the very beginning and starts you on the same channel (food channel?) each time, but after that I think you're in control.

EDIT: OK, so I messed with this some more. It does appear to change channels on its own from time to time, so it doesn't seem possible to see whether they recorded the entire song for each channel. Also, it didn't start me on the food channel this time. Nevertheless, it's not the same each time you do it. I suspect that each channel only contains portions of the song and there are enforced channel changes as a result
There were about 800 games produced for the PS3 [1]. Each dev kit costs about $10,000, nearly all of them used multiple devkits.

Then they get paid by the unit for each game that gets sold.
"The exact licensing fee varies based on the manufacturer, as well as any deals they may give a publisher, but it can generally be anywhere from $3 to $10 per unit." [2]

The console itself is almost always a loss leader. BUT it doesn't stay as a loss leader for the lifetime of the console. the PS3 stopped having a negative margin between 2 and 3 years after it was released (which was also slower than average) [3] This was likely due to the Cell processor which was never really popular anywhere but in the PS3. The PS4 uses far more standardized pieces and should become profitable much more quickly.

There is also a ton of money to be made on delivering content, advertising and indie game markets as well as the subscriptions used to take advantage of these online services.

They also make money on peripherals and controllers.

Of course it's very risky nonetheless as sega demonstrated. But there are also less tangible benefits. By including the blueray player in the PS3 they may have won the HD format war. That alone might make it all worth it. [4]

Early implementations were quite buggy; I tried it in 2010 after a presentation at linux.conf.au and found that the tools simply segfaulted with monotonous regularity on a then up-to-date environment. It's made significant strides since then, obviously.
Actually the first person known to GPU-mine (supposedly an Apple OS engineer, friend of "BitcoinEXpress" on bitcointalk.org) claims he did it in May 2010, wrote his own miner, running on 3 x AMD Radeon HD 4850 graphics cards. The claim sounds plausible. There was a small bump in the global hashrate in May that seems to correspond to the power of this setup.

I commented on it here: https://bitcointalk.org/index.php?topic=40876.msg520645#msg5...

CRISPR: A breakthrough gene editing technique
Yes and no. Unless it is illegal to buy Bitcoins in your country/state/city/area/etc. then buying Bitcoins is fine. Coinbase and the like are more or less established businesses now. If you intend on using them for things that you wouldn't want traced back to you, there are quite a few Bitcoin tumblers/launderies/what-have-you. Once they come out the other side, you have plausible deniablity.
Older news: "Exotic Underground Bacteria Thrive On Radiation Rather Than Sunlight"

http://www.scienceagogo.com/news/20060919234956data_trunc_sy...
The fungi can't break down radiation, no known method can do that(1), and probably not even collect it. The amount of radioactivity is unchanged regardless of the presence of these fungi. They only use the radiation that is there as an energy source.

(1) Bombarding with neutrons or high energy charged particles may change the amount of radioactivity. Also, positron-emitting nucleotides can have slightly faster halflife at very low temperatures. None of these methods are available for the fungi.
How do you handle authentication?
Very interesting, so are they creating an adhoc connection from the device?
No, I think the BS title is the perfect lead-in for this sort of BS article, which provides no details and makes completely ludicrous claims e.g. being able to directly talk to cell radio hardware from an iPhone app sandbox.
The way we handle this (we have 18 internal services) is that processes requiring transactions are formalized into a endpoint/resource. The actual transaction becomes tangible (e.g. you can cancel them by DELETE-ing on the resource) instead of just being documented. Only logic the client needs is the data to kick off the process. Async or long-running processes get a little tricker, but polling or webhook callbacks work fine for us.
Somewhat related, are there any cookbooks on how to "transform a heavy-duty server into several virtual machines"? By this I mean something that includes, among other things, mapping N available external IP addresses to N virtual machines. I realize a good prior understanding of networking, iptables, etc. would make sense. But... still... any well-detailed recipes out there? (I have tried to look them up, but everything seems to assume more knowledge than what I have in mind!)
What's your question, exactly? Coercion and effect aren't intrinsically connected. Something that has a good effect might still not be worth the coercion; something coerced with the best of intentions might still not have a good effect.

I'm pretty sure AirDrop needs either a WiFi or Cellular connection, as the article states, this needs neither.

Also, AirDrop doesn't share with Android and Windows Phones.

Great quote from Knuth/Dijkstra:

I believe that by presenting such a view [on the proper use of goto statements] I
am not in fact disagreeing sharply with
Dijkstra's ideas, since he recently wrote the
following: "Please don't fall into the trap of
believing that I am terribly dogmatical
about [the go to statement]. I have the
uncomfortable feeling that others are making
a religion out of it, as if the conceptual
problems of programming could be solved by
a single trick, by a simple form of coding
discipline!" [29]. In other words, it, seems
that fanatical advocates of the New Pro-
gramming are going overboard in their strict
enforcement of morality and purity in
programs.
Me too. The whole thing reads like a joke.

Glass Development Kit Sneak Peek
I already do it and it's great! Many of my favorite games are on Twitch, Starcraft, Path of Exile, League of Legends, and the best is probably Magic: the Gathering which has awesome tounament streams from StarCityGames and the Magic ProTour all day pretty much every weekend. Combined with a 52inch TV as a monitor, I have yet to plug in the cable into my TV that Comcast forces you to buy!
If this is a strain on deployment and maintenance I would take a close look at those two processes in your organization. We maintain 18+ services (5 people) and having our front-end web apps call APIs only (never direct db calls) has not hit performance, deployment or maintenance issues. In fact, it's helped in all those cases, especially the last two (for us, YMMV yadda yadda).
The last comment says We are being very careful while building our company, so it’s not merely a financial issue.
Yes, I think it makes sense that certain arrangements of DNA would be less susceptible to going cancerous than others. In one strand you might have a possible '1 bit flip' (I'm not a biologist in the slightest) change that would turn the routine into "while(1) {fork();}", but perhaps in another functionally equivalent strand you would need to flip 2 or 3 bits to get the same effect.

So basically you want to select for DNA that has a large (DNA equivalent of) Levenshtein distance to cancerous DNA. Perhaps that is something that you could even deliberately engineer (though I don't think a general solution is possible since determining if DNA is cancerous might be the halting problem?)

Maybe it would be easier to construct a strand of DNA that has the same effect as another strand of DNA, but with more error-checking. Throw in a bunch of asserts or something to send cells with DNA that fails the error checking into suicide mode...
My car insurance in Canada is not public and it is not affordable ($250/month with five years clean driving record) so you should perhaps qualify your statement as well. :)

could you elaborate on where the symmetry breaks down?

From your comment and another one here, it seems to be the case that actually some of the photons that don't hit the sensor still affect the image (either that, or you can't get back to the source starting at the sensor for some of the photons). In other words, if a light source emits a trillion photons everywhere in the room, and your sensor (the idealized camera) catches ten million photons, then it's not strictly equivalent to trace back the ten million maths to the light source, and ignore the ones that didn't make it to the idealized camera.

If it were equivalent, you wouldn't need "photon tracing and ray tracing" or bidirectionality.

But I'm struggling at where the symmetry breaks down, since it seems that tracing a path back from the sensor along the same angles should produce the same result as tracing it forward from the light source - for the photons that directly or indirectly (after a certain number of bounces or passing through the materials) make it to the idealized camera.

But the ones that don't make it to the idealized camera - how can they still affect the frame? Or (equivalently), when is it the case that you can trace it forward to the camera but not backward from the camera?

Why do you need bidirectionality? Where does the symmetry break down?
Ok. I was getting confused by the delay and the initial lack of control. I couldn't tell the difference between a delayed change and an automatic change. Thanks.... point still stands that it's simply a bunch of fake tv clips, probably all the exact length of the song.
You shouldn’t need to jailbreak your device to make PDQ work;
the app alone does the trick. (Whether Apple and other app
store operators will allow PDQ on their marketplaces is
separate matter.)

The author of this article, and more worryingly the developers running a Kickstarter campaign, seem to have an insufficient understanding of the technical criteria upon which Apple admits or rejects apps.
That only applies to base likelihood. Radiation adds a whole new level onto that by altering the structure of the DNA when it hits it. You could completely eliminate inheritable chances of cancer but still end up with cancer patients as a result of radiation poisoning,
I bet a lot of people would fall in the category 0-1.

Our public API is a front end for our other services with auth added on and better guarantees against breaking. We don't depend on it directly for anything public facing and I wouldn't suggest anyone completely rely the same API they offer partners/openly to avoid getting into a tough spot with managing changes.
On Flippa, 1 year trailing revenue is about average or maybe current/average month revenue x 12 months. Anyhow, some are more, some are less, but that's about where the market prices seem to be.
That sounds like more of a problem with the average VS/Windows dev than of intellisense.

Surely you use autocomplete or typeahead in emacs, right? It's just about saving time.

Intellisense isn't "I dunno what I want so I'll wander around." It's "I know exactly what I want and want to type as little as possible." VS also supports Emmet/ZenCoding, which is an extreme example.

My Santarpios conversation happened about 7 years ago.

Santarpios is great and highly recommended. Galleria Umberto's is possibly better though (and far easier to get to).

I've just remembered that when I was waiting at a gate (before boarding had commenced) at LAX about 3 weeks ago, there were about half a dozen very young looking TSA agents receiving some training at the gate about how to approach people, being reminded to keep it friendly, etc. They then wandered off to another gate and I thought nothing more of it.
We do have problem employees and management feudal battles -- although I have only personally witnessed the latter. I have only worked here, not counting internships before I graduated, but I hear from colleagues who worked elsewhere that these two problems are of a lesser degree here.
Haven't tried ViEmu, but vsvim is actively maintained. Lots of fixes have gone in to making it play more nicely with other plugins like ReSharper. Compared to vim emulation plugins in other editors like sublime text or even emacs, vsvim provides some pretty good coverage of vim features. Don't expect vimscript support or anything - the modes are pretty good though.
Been a while since I've posted but here is what I know:
Gold & Silver. A lot of people who trade commodities are actually moving portions of their investments into Bitcoins. It wouldn't surprise me in the least if there are a lot of Chinese buying Bitcoins but the few people I know around the world are from the commodities market.
For IP address or locations? No clue. Wish I could help you there but I'm not sure.

I would say we have a bit of a ways to go before the big boys come into play from the stock market. They're going to be looking for more stability which Bitcoin doesn't offer yet. I think we'll see a progressive transition of portfolio diversification to account for newer currencies. So we might see something like:
-10% Cryptocurrency
-25% Commodity
-10% Bonds
-55% Stocks/Money Market
^very rough example.

Disclaimer: I'm not in Bitcoins but watch the charts throughout the day. Just my speculation of what is happening based on the grape vine.
What it means is I'm hesitant to believe an 18000x speedup.
It was made pretty clear that the app is using the WiFi and bluetooth radios, not the cell radio.
A lot of older houses here (NZ) have the door handles about 3/4 of the way up the door, about chest height for an average adult. I always assumed it was to keep them out of reach of children. In modern times they've moved down to waist height, most likely for accessibility. Which also makes them accessible to kids and pets.
But I can't expect that I will be able to exchange the BTC for a fixed amount of electricity, which is the same as the fixed amount of electricity I originally exchanged for BTC. Hence BTC is not convertible, and not "backed"

I can buy gold with the US dollar, but it doesn't mean the US dollar is backed by gold.
> I'm pretty sure AirDrop needs either a WiFi or Cellular connection, as the article states, this needs neither.

No, AirDrop does not require wifi or cellular. It uses Bluetooth LTE to scan for nearby phones and then establishes an ad-hoc wifi connection.

You can't use it if you have wifi turned off (or airport mode turned on), but it works whether you're connected to a network or not.

> Also, AirDrop doesn't share with Android and Windows Phones.

And as of November 19 2013, this does not either.
I keep seeing this radio program referenced every time a thread comes up related to (blah blah ACH...).

So I listened to it. It wasn't that interesting. If you had never heard of ACH before, it would perhaps be illuminating, but if you already have a decent grasp of the existence of this system and it's shortcomings, there's not a lot more meat in that program...

YMMV.

Your dropdown for interest in "write an essay" should sort alphanumerically. Woodworking shouldn't come before Minecraft.

From a UI perspective having a list of zillions of empty interests is a problem. So you think heavy metal is great, well cool so maybe this will be a heavy metal related people and topics kind of website. Or would people who knit clothing fit in too, presumably in different interest areas. And hows that all going to fit on one enormous page of interests? Is this the main university library or the small specialized school of music satellite library focusing solely on music?

(edited to add, and do essays and interests age out, so if no one ever posts to woodworking, after a month thats the end of that. Or...)

You seem to 1:many map a post into an interest. Its probably more of a many:many tag like structure. So for the sheer heck of it I posted link to a wooden clock I'm building in woodworking. Now that you'd "tag" as clock-nuts or fine-woodworking or noob or whatever. Or are you going for something like "IRC on the web" where theres "a" room with "a" name and its not twitter tag time, which is a perfectly valid plan.

Is this your idea of a minimum viable product and if so, where to go from here? Or rephrased, what do you plan to do with it?

Which really puts the lie to the idea of currency being "backed by" a scarce resource at all, which is the main premise of goldbugs. I'm totally okay saying that a currency is backed by the entire economy of goods being exchanged for it myself.
I mean, will this work after Apple patches their OS so you can't breakout of the application sandbox? This is pretty cool and all but it seems to me like a bug. Something they should report to Apple (or Google/Microsoft) get some sort of reward from a bug bounty program and be on their way.

I thought the app sandbox was designed to specifically prevent app makers from accessing the hardware in unauthorized ways. (I am guessing Android and Windows phones have similar ways of controlling access to the hardware). This seems like the exact use case that should be stopped.
