Note that the term "unreal mode" is already historically taken to refer to running an x86 processor in realmode with unlimited segment limits (http://en.wikipedia.org/wiki/Unreal_mode ).

What I find most interesting about all these protections is that they theoretically could be defeated completely with a series of small single-byte changes, since ultimately everything rests on a series of decisions (conditional jumps) - "is the certificate valid?" "is the certificate trusted?" "is the user allowed to do X?" - and all that you have to do is make that decision always go one way or the other. It doesn't matter how much crypto is behind that verification, it all rests on that one decision, literally a one-bit difference in the output of a gate in the CPU at runtime. Even if the OS itself doesn't allow this, as long as there is no real decryption involved, you can boot a LiveCD or remove the drive and plug it into another machine. "Secure boot" and TPM just require going a bit deeper into modifying the BIOS itself, but the same principle of changing the decision applies.
I think he's criticizing the cultural caricature that accompanies any activity becoming mainstream... but perhaps misdirected as the context in which one finds value isn't really important in contrast to value itself. Perhaps the elegance is in how deeply individual a practice it can be (turning the locus of one's awareness inward).

And to the OP, isn't it great that yoga can hold so much value through both a spiritual and physical lens? I think the mental and spiritual component has a lot to offer, but it's hard to claim that someone pursuing a positive activity, regardless of motivation is a bad thing.
I think many people (including Siddhartha or Buddha) used to walk for meditation. If that's the case, and you practiced mindfulness while exercising it might be possible to do both at once.

Often when you hear of great athletes, especially great endurance athletes like Michael Phelps, they talk about how they don't think about the whole X meters or Y miles at once. They focus on performing the next stroke or next step or next pump of the pedal perfectly. This to me, as a layman, sounds similar to the idea of focusing on the next breath as is a common practice during some types of meditation.

When I used to meditate I used to like to let my mind wander, then focus on breathing. Or vice versa. And many people prefer guided meditations.

As there are so many types of meditation I do not see any reason to believe that some types might overlap with exercise quite comfortably. Guided meditations might be more difficult because it would presumably be harder to both focus on the next stroke and focus on the meditation, and I guess that goes as well for the wandering mind meditation (you really don't want to run absentmindedly in NYC where I live, maybe in the country or even suburbia it would be more feasible).

Anyways, I guess to me it doesn't seem like it has to be an either or but could be one activity. If Siddhartha can do it, so can we :-).

I should start running again though, that's great exercise!
> That's like comparing a lit-match to a gas pipeline fire.

That's a terrible analogy. Radioactivity, a nuclear reaction, deals with totally different physics and phenomena than combustion, a chemical reaction.

A more proper analogy would be: Would you rather me shoot you with a cannonball once right now, or would you rather me split it up into a million little BB pellets and shoot one at you a day?

I'd choose the million little BB pellets a day because my body can recover from that in between. Likewise, your body constantly repairs DNA damaged by the sun or from other radiation sources.

Radiation, activity, and dosages are extremely difficult to keep straight. Especially when coming from the media. Not even units can help you (ex: Equivalent vs Effective Dose), and it is hard to keep straight (ICRP vs NRC).

> Only the fire doesn't end - because we don't have the technology to stop it, and perhaps will not ever.

I am not quite sure what you're referring to -- stick yourself in a heavily-lined lead chamber and I'm sure you will measure far less gamma radiation inside of it than outside.

> So no, I don't agree - likely the number is much less than 507 and uncomfortably close to the number of plants already in disaster-mode.

Then we can agree to disagree -- it seems you have already made your mind on how many plants are close to "disaster mode" (unsure what that really means in an engineering sense).
Wouldn't something like this cause extreme eye-strain and/or headaches? Even if you could make sense of the display...
As long as you do your caching correctly, performance will be good. But you can't do caching with dynamic content, and PHP, while these days getting a lot better, there are some faster tools out there these days. Still, this project looks interesting and I'd like to see an English version of the demo so I can understand what's going on.
Ask HN: How can we solve diversity in tech talent without allocating quotas?
Most commentary and discussions tend to highlight % of people by gender and race, while hinting at allocating quotas in order to bring better balance to the work force.

I feel this maybe a flawed approach and there could be a better way to address diversity without going down the quotas approach.

What do think?
But as a user, I find it frustrating. There are companies that I follow because I want to see their news updates. I want them to advertise to me. That's one of facebook's major functions - following people you like and getting their news updates. Well if one of the "people you like" owns a local business and you want to follow his page in addition to hismelf? Unfortunately, you don't get to see the updates unless he pays facebook.

I get why facebook does it and I really can't blame them, but as a user I'm disappointed that I can't fiddle with the knobs and say "I really actually seriously like this business and want to see every update of theirs".
A meltdown doesn't necessarily put any radioative particles into the air. If it did, that would be a very unusual event (such as Chernobyl). On the other hand, a bomb has a tendency to put an ultra-fine dust of uranium, various transuranics, and quite a few fission products into the atmosphere.

I suspect that you may be confusing a radioactive isotope (such as U235) with the particles associated with nuclear radiation (such as alpha and beta particles).

A meltdown will generally involve a lot of radioactive material. It will usually be localized and only very rarely pulverized into a dust. Chernobyl's steam explosion did this. The meltdown will probably also emit a lot of radiation, but that never "contaminates" the atmosphere, unless you consider electrons or helium "contamination".

Unfortunately, conflating radioactive isotopes with the radiation those isotopes emit when they decay is very common misunderstanding.
I've been using the Headspace app for several months and found it to be very helpful. While doing the exercise, which is a daily 15 minute guided meditation session, I feel much more relaxed. And throughout the rest of my day I find that I'm more aware of my reactions to various events and sometimes I'm able to step outside an emotional reaction and see what I'm doing, and whether it's actually how I want to act, and then behave accordingly. It's no panacea, but I have found it useful enough to keep doing pretty much every day despite the friction which tends to lead to giving up on good habits.
If your product really does link something together, it sounds like an extremely good name. There's no negative connotations, and it's easy to pronounce and remember. I'd say go for it.
Fascinating story. The one "homeless" person I know firsthand is also doing it by choice. He's employed, and simply chooses to be homeless because it's not a very difficult life for him. Meals at the community kitchen or the restaurant where he works as a cook, showers at friends homes, or the local university student rec center, sleep with friends, in the park, or at one of the many university buildings that are unlocked 24x7.
I think the "language of the future" will be the one that will allow people get results fast with little or no training. In other words, something that requires low skill. People hate learning and all they want is a magic button that just makes things happen (for the record, writing this doesn't make me happy at all).

Also, I predict something similar to the industrial revolution in software engineering, when high-skill difficult manual labor is replaced by factories operated by cheap low-skill workers.
Arguably the most versatile compiler in the world is EDG's.

One of its features is: "a C-generating back end, which can be used to generate C code for C++ programs"

source: https://www.edg.com/index.php?location=c_frontend

In fact, the Itanium C++ ABI (which has no relation to the architecture) specifically uses valid C identifiers to mangle C++ names to support products like EDG.

yup...all that adds in
Domonic O'Brians methods work like magic with relatively little practice. They're also a form of meditation in some sense because of the concentration required to use the imagination so vividly. He has a six cd course I've never gotten all the way through but the techniques I employed helped me remember french vocabularly, art history (dates, names, etc), people and their names, and phone numbers with relative ease (especially compared to rote memorization). The best thing is, the more you do it, the better you get and the easier and faster it is.

Looks like he has many books [0] here on Amazon. He won the World Memory Championships a number of times.

I'm no expert, but I suspect there's a big difference between the planet's naturally occurring radiation and the high volume of unstable particles spewing out from the Fukishima meltdown everyday.
It's a paternoster! Only with magnets instead of cables.
Jesus, these comments are so pessimistic. As of now, the three top-level comments are "Wouldn't this cause headaches?", "Wouldn't these have a uselessly small viewing area?", and "Wouldn't these be too blurry?". Come on, people; have some imagination. These aren't even show-stopping physical limitations (which humanity has sidestepped thousands of times before); these are relatively minor engineering problems.

Even as someone with essentially no experience in this area, I can think of a few potential solutions to the complaints thus far. The eye strain and focus issues are solved by using pre-collimated laser light instead of LEDs. Our fabrication isn't quite there, but again, it's an engineering challenge. The viewing area size is expanded by eye tracking (possibly via sensors in the contact lens).

It's good to question these sorts of things, but at least start with interesting questions!
Also, the experiment's requirement lead into the operators disabling almost every single safety mechanism. The automated systems disallowed the actions they were trying to do, so they disconnected most important security measures.

Operating like that you can make even hydroelectric power station extremely deadly, and kill a lot of people.
There doesn't appear to be much of one, yet. The latest commit by indutny was just a commit to node that the owner of the iojs GitHub organization pushed to GitHub. There are no public members of the iojs organization. Even the name of the repo, "evented I/O for v8 javascript" is the same. All that's been introduced here is a new name, io.js.
Homeless tend to flock to where it's easiest to be homeless. Definitely seen this where I live, over the past 10 years the city has devoted considerable resources to "homelessness" and during the same interval our homeless population has exploded. Used to be able to walk around downtown and never be bothered, now panhandlers are everywhere and even assault and robbery (previously almost unheard of) are more regular.

Actually, I've heard many-a-monk describe meditation as training the mind, so the goal is often to 'get a better brain'. Not to mention, an improvement in the brain's mindset is necessarily linked to physical changes in the brain. Furthermore, a sexy body is often chosen to be sexy because the body is healthy and happy in the first place. These motivations are not superficial in my opinion, but rather natural to the human condition.

Exploring the physical and mental benefits of these practices gives a context for practicing meditation in the first place. It takes many years of meditation to be able to consistently let go of 'selfish' desires (emphasis on the ambiguity of selfishness). Entering a practice without a well-defined reason for doing so makes motivation hard to come by. For most folks, the deeper benefits of meditation are only understandable after much dedication.

Anyway, I believe meditation is a means to more than one end. ;)
This article hits home for me. I was born with a severe hearing loss, and I have recently got a Med-EL Opus2 / RONDO Cochlear Implant -- which changed my life for the better.

How?

It reduced so much stress, I was surprised that I was carrying so much. It was simply things like going to the toilet (you think, "am I going to make a really awful rude noise that everyone will hate me for?") or drinking your coffee ("is this awful?!")... even typing at work, or taking to a colleague and hoping that I wasn't interrupting someone else.

Then I realised: everyone else is simply bloody loud, they generally don't care about how loud they are when they're eating, shutting doors or chatting to someone. They don't. Only I did, I was the only one who constantly worried.

It wasn't the fact that I could suddenly hear things, which I could, it was realising that I was overthinking, overanalysing every situation with that sound was involved. That included _breathing_. I would literally slow my breathing if someone were to sit next to me on a bus. Severe anxiety due to sound.

I'm still very anxious if I am to watch a movie, in my own house, by myself... in fear I'd wake the neighbours on an adjourned property. (to put this in perspective, my wife came home and she couldn't even hear the movie in the next bedroom.)

THIS was seriously the hardest thong I've had to face but it's been worth it for the reduced stress and anxiety.

Thanks for posting this!
One reason I like it is that you're probably going to be reading in the possible values from a stream or arg or config file anyway.

Here's the thing though: the marketers who are serious about paid media, and spending a significant portion of their budgets on it, tend to know that those algorithms exist and are smart/experienced enough to monitor and manage their campaigns accordingly. If you have good margins and/or a solid customer LTV, "boom to bust" isn't likely. If you don't have good margins and/or a solid customer LTV, the eventual demise of your business is the result of the economics of your business, not your marketing channels.

From what I can tell, a sizable number of the folks who have been running around treating Facebook Pages as owned media probably don't even know what "owned media" is.
The premise of the article:

1. "To accept that hunters are affluent is therefore to recognise that the present human condition of man slaving to bridge the gap between his unlimited wants and his insufficient means is a tragedy of modern times."

2. "There are two possible courses to affluence. Wants may be "easily satisfied" either by producing much or desiring little."

Following this definition, it's easy to accept hunters are affluent if it can be shown hunter-gatherer tribes worked as needed and desired nothing.

The article makes no mention of whether this kind of society is sustainable over the long run, only that this kind of society, where it exists, is affluent.

I like the thought - to perpetually chase the limitless with the limited does sound like a fool's undertaking.
Wahoo, hope people are more open to change this time around – hope it works out!
Octopus to Leave RavenDB for SQL Server
I browse with JavaScript turned off by default, and have ever since I saw a pretty cool DEFCON (I think) presentation on the number of gaping holes it makes possible. I'll sometimes enable it for a site, but I'll also sometimes just not use a site.

I really don't like the fact that this is getting more and more difficult to do. The Web is not about allowing random people to execute code on my computer; it's about reading documents and sharing information.
Nope, what Rapzid said. My code very rarely compiles first try, but when it does I have a strong amount of certainty that it will work. So I only have to run it a few times a day to check on the output, rather than every single time I compile it. Nobody said anything about releasing it without running it.
> A PhD is one of the few opportunities in academia to do true, unconstrained, open ended research.

Sure, but is this really in conflict with publishing articles? The sort of scientific advances that require a full book or dissertation for a proper treatment are few and far between.

Also: doing true, unconstrained, open ended research as a PhD student is taking a big risk, one that is (a) quite likely to prolong the time necessary for completing the PhD and (b) almost certainly a bad idea if not done with the full support of their PhD advisor.
A good way to see the high-persistence blur he's talking about: physically move a tablet screen up and down while reading a line of text. Do it just slow enough that you can track it and there is no blur. Now start over and scroll the screen at the same speed and direction you were physically moving it before, and try and read the same line. You should see much more blur.

People talk about these sites every once in a while. But my experience is that enabling JS makes things worse across the board. If there's some site that would perform better with it, these are very much in the minority. And in my experience, "old web" sites with out JS loaders and such are almost always much faster & easier on the resources.

Even if some sites deploy instrumentation, it doesn't mean they're necessarily lifting a finger to make it faster for me.
I have no physics education, I'm using common sense. They don't design bombs like they do core reactors. Bombs are intended to explode immediately, reactors are intended to help produce power for a very long time.

Like what Tyler said, balance shafts to counter a single cylinder would be huge but also they'd add unnecessary complexity that could otherwise be overcome by adding additional cylinders instead.

Furthermore, in order to obtain the same level of torque in a single-cylinder that a multi-cylinder engine creates you'd have to account for the power generated per cylinder.

In the Wartsila RTA96C you have HP up to 109,000 (rounded) and torque up to 5,600,000ft-lbs [1]. These #s are for all cylinders. Assuming it is the 14-cylinder variant generating this power and you want to reduce this down to a single-cylinder package then you can easily deduce that the displacement would be around 25,480 liters (mentioned elsewhere in this thread).

Assuming a stroke to liter ratio of 1.374mm/liter (2500mm stroke for each 1,820 liter cylinder) you'd end up with a 35,009mm stroke for a single-cylinder engine vs. a 14-cylinder engine. Since there are 25.4mm in an inch that's a 98-inch stroke for 14-cylinders vs. a 1,378-inch stroke for a single-cylinder or an 8-foot stroke vs. a 114-ft stroke.

Finally, since you'll need a piston many times larger than the current setup for a single-cylinder vs. a 14-cylinder engine then you can imagine how much mass you have moving which can do some serious damage if it becomes unbalanced. Also you'd have an engine that instead of being long and relatively low is now very short and extremely tall (not something you want in a ship where capsizing is a very real concern).
