Any hydrogen leak would rapidly rise away so it's actually quite safe. Certainly much safer than gasoline and we use that every day - including sparks.
I wouldn't worry about internal heat damage so much. With the development of thin and passively cooled (i.e. chassis-as-heatsink) devices, human skin is becoming the temperature limiter[0]. Many chips are "...capable of running at up to 100°C without any reliability problems", but your skin is normally only 37°C!

WRT. YouTube vs. downloads, WiFi (all RF, really) produces more heat than you think and GPU's have come a long way in power/heat savings!

Not the best phrase choice.
The average user of sage is a phd in a field that uses maths extensively. I really don't see how you can think that someone like that is dumb enough to not be able to debug a python function call to the point where something went wrong. It is literally one days worth of work to learn how to use the python debugging tools and it's largely trivial compared to the everyday work you do.

ReadMe founder here. Thanks for including us! Your analysis of ReadMe in the areas you covered was spot-on; API flexibility is definitely a weak spot for us currently. We left it intentionally slim on features during launch to see how people used it. Over the next few weeks, we'll be rolling out huge improvements to the API stuff. (Side note: You wouldn't believe how different every single API is. It's crazy.)

One thing you missed was the ability/ease of non-reference guides. No matter how good your API reference is, it's like handing someone a dictionary and telling them to learn English. Topical guides, tutorials, and more are insanely important.

Ralph Nader to Apple: Fewer Buybacks, More Worker Pay
But you can still take out that SIM and put in one you got from your provider (or bought as a prepaid card in one of a zillion of places), can you?

If not, how does Apple plan to sell these phones in Europe?

Quote from the paper:

> To avoid the usual problems with floating point arithmetic (rounding, truncating, instability), we construct all our examples with integers.

I think this is complete overkill. I know floating-point arithmetic can be tricky, but it's not at all random. If you have a stable algorithm and a multiple precision floating-point library, you can use floating point numbers. It won't necessarily give you a proof that your result (unless you spend time to derive rigorous error bounds), but it will certainly be good enough.

I think people sometimes do slightly irrational things for fear of floating-point arithmetic.

soooo, nest still wants the thermostat itself to be the hub. a power constrained, proprietary hub with wifi and thread (when it is actually released). Rather bizarre in my mind.

There seems to be a hub phobia. I'm not saying it makes tons of sense to have multiple little servers for every device but I look at things like my kitchen and wonder, which heating hub I would choose. my microwave, oven, toaster, etc.

If there is going to be some kind of singular hub (which would be great) it needs to run apps and have expansion capabilities for the radios. A nest will not cut it. Also, without nest having thread enabled, the only way for things to talk is over wifi (nest <-> api.nest.com) and http. not bad for consistency but it sure would be nice to have all of the communication stay in the local network.

On another note, my San Fran apartment doesn't have a thermostat....

There are two kinds of scientific progress: the methodical experimentation and categorization which gradually extend the boundaries of knowledge, and the revolutionary leap of genius which redefines and transcends those boundaries. Acknowledging our debt to the former, we yearn, nonetheless, for the latter.

-Academician Prokhor Zakharov, "Address to the Faculty"
It seems you're arguing theoretically, and that maybe I moved a little too quick in my previous post and wasn't clear.

What I actually suggested above was buying the SPYs and selling covered calls. The only risk you're taking on is limiting your upside to your strike price.

Tell me this: what can an investor do to increase his probability of success in a trade other than reducing basis? The argument for reducing basis is simple: Reducing the amount you've paid for the shares, making them cheaper for you than somebody just buying the stock, gives you an edge.

The monthly sd in SPY is $9. So yes, if you sell the $205s, 85% of the time the calls you sell will expire worthless OTM, and when that happens if you roll your position forward another month, doing that will increase your total profit over just holding the stock. Limiting upside to increase odds of profitability is the lynchpin of professional trading strategies. And that's what you're doing here.

And yes, selling 1 and 2 lots, commissions do absorb a larger percentage of your PL than on bigger transactions. And complex strategies that require 4 legs like an Iron Condor won't be profitable at that size, it also happens that an IC is a low-risk strategy (and thus small effect on your buying power) so in those cases you can increase the leverage or widen the strikes.

Your attitude about options is understandable given the way they've been portrayed to the retail investor. And everybody should think about what's right for them. But most retail investors buying stock, making directional bets, buying netflix at $500 a share, you think that's less risky than buying a $100 debit spread on NFLX with a higher probability of success and massively less capital. And you think that way because it's how you and the retail sector has been conditioned for 20 years.

And, like I said up top here, the retail sector has underperformed the market. And it's not because of evil HFT firms who do nothing but cheapen transaction costs for everybody. It's because of the way we trade. It can be better. Check out this TastyTrade video covering a study they've done on reducing cost basis with covered calls:

Indeed, I find it surprising that there's no filesystem flag giving the opposite behaviour to "compress contents to save space": something like "transparently store this file bloated by a fountain codec to ensure integrity on an bitwise-unreliable backing store" or maybe "transparently generate a Parity Volume Set from this file and stripe it across the disk to protect against lost sectors."

Both of these options would protect your important files against failing single disks without having to do any RAIDing. The unimportant data (e.g. the OS itself, caches, etc.) could be reduced-redundancy, since it doesn't need to be captured in a disk rescue.
I have an idea for an app
Here's an idea. Create a Google Alert for the phrase "I have an idea for an app."
I think that's not right at all. Sage is a fairly massive project, most of which is implemented in separate libraries (not necessarily in python) that are then bound together under sage. To say that you need to know how to debug a python function call is a great understatement.

The function call is not the issue. The issue is that it is a large unfamiliar code base, and the bug, as in this case, would not be an incorrect None somewhere, but will be a mathematical bug somewhere, like an incorrectly written formula. Chasing that is far far more difficult.

Bearing in mind also that the average phd mathematician has at best cursory knowledge of programming and software engineering, enough to get on with mathematics, expecting them to dive into sage and fix things is just unrealistic.

> it's largely trivial compared to the everyday work you do

I think this is also a very unrealistic expectation of users, however skilled they may be as mathematicians.

There's a lot of science or research related to meditation. I like mindfulness meditation. Meditation definitely seems to reduce negative emotions, and also cultivate positive ones (or at least make space for them).

"Mindfulness meditation programs improved multiple dimensions of negative affect, including anxiety, depression, and perceived stress/general distress ... the effects were significant for anxiety and marginally significant for depression at the end of treatment, and these effects continued to be significant at 3-6 months for both anxiety and depression"

http://en.wikipedia.org/wiki/Mindfulness_(psychology)#Overal...

"[Loving-kindness] meditation practice produced increases over time in daily experiences of positive emotions, which, in turn, produced increases in a wide range of personal resources (e.g., increased mindfulness, purpose in life, social support, decreased illness symptoms)."

They don't need to know that he died clawing his eyes out and screaming for mercy; the real story would just hurt sales."
I've managed tons of product launches at Airbnb, Munchery and other startups as a consultant.

Do not launch on Thanksgiving. Trust me. Delay until the week after.

Also you should know that Thanksgiving through New Years is by far the worst time of year to try and launch a new (consumer) product of any kind. Every single (consumer) product in the world fights a bloody battle for attention and sales this time of year. Every store, every brand and every product category will be filled with promotions and/or slightly new offerrings.

If you must launch during that window, what you're launching must be either a) fucking amazing itself or b) your fucking amazing at marketing to cut through all that noise.

It is unlikely they were actually infected using an exploit though. These tends to be very targeted attacks. That being said, for those that do tend to be targeted, I am thinking that getting people to authenticate emails using S/MIME would be a good idea.

The major difference between Lua 5.1 and Lua 5.2 is the environment a function operates in and this effects globals and modules in a rather big way. You can change the "global environment" a Lua function operates in quite easily in both Lua 5.1 and 5.2, but the underlying implementation is different between the two, and Mike Pall, the writer of LuaJIT, does not care for the new way globals are handled. There might also be issues with supporting Lua 5.3's integer type [1] in LuaJIT (now you use the C FFI to handle 64-bit integers).

At this point, it seems there are two distinct versions of Lua, Lua and LuaJIT. I have some modules I wrote that support both Lua 5.1 and Lua 5.2, so I can still use them with LuaJIT if need be, but it's a pain (conditional code in both C and Lua) and it will only get worse if Lua 5.3 comes out [3].

[1] Up to Lua 5.2, Lua only supported one type of number (internally, a double [2]). Lua 5.3 now supports a distinct integer type, which has its implications (doubles don't wrap; you now get x.0 where before you would get x when printed, etc).

The reason for 64-bit integer support is that doubles only support integer operations up to 2^53 or so. [3]

[2] Unless you changed the internal representation of numbers in Lua, an easy change to make in the Lua sources.

[3] I already had to work around 64-bit integers in some code dealing with process limits on a 64-bit system and Lua 5.1/5.2.
To balance those links to videos, a text from "the other" point of view:

http://badufos.blogspot.co.at/2013/04/that-citizen-hearing-o...

"To lobby for "disclosure" implies that there is something to "disclose," which is highly dubious. And to hold a valid "hearing" implies that witnesses are queried under oath, which of course will not be the case, leaving them free to fabricate as much as they please without fear of repercussions. The five former members of Congress are being paid a reported $20,000 each by Paradigm to participate in this circus."

Kin utterly failed in execution, too late, too buggy and crippled (due to common Microsoft pathologies), the carrier plan was too expensive for the target market, which at one time was at least somewhat healthy (T-Mobile Sidekick).

I would argue the senior staff may not be dumb, but much of their staff is another story. For example, I was working closely with Verizon staff while they were petitioning the FTC to allow them to raise 411 rates. Their argument for the required rate increase was that they were loosing customers to things like google 411 search, so they need to raise rates to keep their service profitable.

How's that for logic? "Hmm, we now have competition for our product that is better and cheaper, oh well we better just raise our rates." Meanwhile they were very slow to make improvements to their product as a means of countering competition.

This reminds me that MS used to have an export to HTML feature in PowerPoint, but it was very IE specific and they removed it in PowerPoint 2010 I think instead of fixing it.

If using integers doesn't do a disservice to their findings, it makes complete sense to avoid the can of worms that is floating-point arithmetic.

> Fourier Transform became trivial to me when I noticed that it's just a basis transform

I always thought this was the definition of Fourier transform, and all the stuff with integrals was just to express the change of basis in an explicit form. What else would the word "transform" mean?

How is it even possible for someone to learn about the Fourier transform without it being very explicitly said that it is a change of basis to a different set of orthogonal functions? Did they just introduce the integral expression for it and hope people would memorize it? I don't understand.

Thanks for the feedback! It still has some rough edges, but I'm really glad to see how people respond to it.

Yes, that's the idea. There's also a mechanism to strengthen the strongest causal relationships through upvoting and downvoting. This way, hopefully the most reasonable links show up on top, but everyone's opinions can be represented.
