When you're skiing or wrestling, you naturally engage a significant number of muscles and position your body to engage in said activity. When your whole body is in motion you instinctively flex your muscles to do things like balance, twist, bend, jump, etc. A body in motion is essentially in a more healthy alignment and supports your passive body parts (bones, blood, nerves, organs, etc).

When we are still and calm, our muscles relax (in general). This is basically a bad thing for our bodies because it stops the support that a lot of our body needs. For example, letting your neck sag forward or hunching over your desk over a long period of time can damage parts of the neck and spine, overdevelop your deltoids/chest and hurt your lower back.

When you're doing yoga asanas, this is all exacerbated as you intentionally put your body into positions that we don't naturally move into without lots of practice. So in effect, it's significantly more dangerous to sit on a mat if you're not engaging your muscles or positioning your body in the correct way to support everything.

Yoga is dangerous in the way that every physical activity that requires skill to perform is dangerous, with one caveat: yoga asanas are dependent on the way you personally move your body and the state it's in. So really, it's only dangerous for people who naturally move their bodies in a way that might promote injury. This is why learning from a teacher how exactly to get into a pose, and practicing that regularly, is so important: it removes ambiguity and improves the entire physical act to not only be safe, but also be superior to how you might naturally do something.

But as a practitioner, I don't personally see how yoga is any more dangerous than skiing or wrestling. You can break an arm in wrestling, and a collarbone in skiing, if you're not careful. Just because sitting on a mat looks easy doesn't mean it is.
Then again, I think many, many problems actually break down into these categories if you look at them long enough, which is why we've had so much effort put into these.

Yeah, all one-two guy products made by them in their free time as it seems cannot be a match for open-source projects.

Java mentions Haskell quite a lot, Haskell mentions Java almost not at all.
I believe its a deep feeling of inadequacy. We are not his peers. He considers Gates and Jobs as his peers.

I suspect that despite his achievements he may have felt a bit like a peasant in their presence.

He may have wanted to achieve their fame and wealth.

He thought IV would be a good vehicle to achieve fame and fortune. I think he may not have understood the deep revulsion of the engineering world towards his methods.

He may have initially thought we would consider him a savior working for our benefit ... after all I think he used to believe he was doing it for "inventors".

Now he is too far gone probably. He either no longer cares what engineers and the world thinks, or he has deluded himself into thinking that his scamming is good for the world.

Either way, he will probably carry this infamy to his grave.

Although, I have to say, our country has a way of rehabilitating robber barons who give their wealth away. So his end-game may be to take his enormous wealth and use it to destroy some terrible affliction of mankind.

I think it would be a triumph, and perhaps ironic(?) if he took his wealth and used it to reform the patent system.

But short of that, he will probably be remembered by those of us in the tech and legal fields as a scammer and a scumbag of epic proportions, who was protected in his thieving by the laws of the USA. In any other time or place, such a man would have been tarred and feathered by a posse of his community for his conspiracies and crimes.
Launching Open Web Apps feedback channels – help us make the web better
The Ferguson Question
To answer your criticism to the original criticism:
1) Rails is not really THAT expensive, especially when you're just trying to build a small business website. The people who complain are actually the ones who are exactly working on those "funded startup" you mentioned.
2) There are tons of huge apps out there that run on rails just fine. You hear about stuff like Twitter switching to other language because rails is "too slow", but Twitter is like the rarest exceptional case you'll ever find. I mean, do you know of any other web app where realtime is as important as Twitter AND is at such a huge scale? Most websites don't.
3) It's actually more like "Most of the times you use readily implemented libraries and in rare cases you need to use your own". You can't iterate fast when you have the mindset of trying to fix everything. You need to pick the most important problem you're trying to solve and do whatever it takes to reach product market fit as quickly as possible. I have played around with node, express, etc. to build webapps and was at first very intrigued. I did that for a while, and then got frustrated with the lack of convention i can just mindlessly follow as well as all the convenient tools rails provide. So I came back and couldn't be happier.
He probably means that foreign key support should have been added in a far earlier version of Rails.

How to Break Cryptography With Your Bare Hands
I think one of the difficulties is that in a short space of time it's hard to get everyone up to speed on a complex body of code. So I can understand why training courses are somewhat forced to revert to smaller examples that everyone can get in their heads quickly - otherwise you would spend a huge chunk of time understanding the code base.

For me it wasn't really about the code itself, it was more about learning the process of breaking problems down and then applying different refactoring techniques to increase the abstraction.

One of the best parts of the class was the discussions/code reviews and Sandi really does knows her stuff. My classmates and I had many deep discussions with her on a wide range of topics and she was always able to explain things in a clear and concise way.

Perhaps if you are a senior ruby developer of many years experience this course wouldn't be the best investment but I would definitely recommend it for junior/mid range developers.

A large amount of it is managing the delay of gratification; I believe that is what you mean here. It is a discussion in psychology, and you can find a bunch of research on it for instance the marshmallow test.

I would challenge you to do some meditation- like just stopping and relaxing and focus on just your breath, once a thought pops into your head just come back to the focus on your breath. Try it for 2 weeks 5-10 minutes a day record your results.
Because PHP is so readily available (installed on pretty much every free web host), it may also be related to people starting out with programming and getting frustrated about it.
You'll find very few workloads where Haswells doubling of vector sizes actually doubles throughput. I mean, if you're working set is already in your level 1 data cache it will, since you won't be bandwidth constrained in that case and you won't have the wide vector unit on long enough that the chip will have to start power throttling. This is a situation that comes up sometimes, but you won't see your program accelerate by anything close to 100% overall.

Namecoin is one way. But why do you really need an authoritative registry? Think about Google's Real Names policy. Who does it benefit? If I don't want you to see my real name, why would I want you to find me by my real name? You should be able to find me only through existing connections you already have established in internet space.

If you want some authoritative distributed hash map, you can use namecoin like you said. But think about why you actually need an authoritative registry.

Hyperlinks? The document embedding the hyperlink can also embed the IP number. In fact, that's how the underlying IP routing system works. BGP isan interesting target for spoofing as of late.

At the very least, a website wishing for others to find it by its domain name should tell more than one registry, so there isn't a single point of failure. In the trade-off between consistency and having no single point of failure, you can think of the latter as failover or backup plan.
Closing the socket results in a race condition. You might close the socket, and then another thread opens a new file or socket and happens to get the same fd as your socket used to hold. Now your reader reads from some random unaffiliated fd it shouldn't be touching, causing all sorts of havoc.

A timeout will work fine, but now you're polling, meaning you have an unpleasant tradeoff between efficiency and how long it takes for your thread to notice that it's dead.

Canceling select or any other multi-fd call is really easy. Create a pipe and add it to your fd set. Any time you want the thread to wake up (e.g. because you need to tell it that you're canceling something) you just write to the pipe.

Signals have a similar race condition as closing the socket. If the signal is delivered after you check for cancellation but before you enter the system call, you'll hang.
Is licensing an ARM core really a barrier in a business/community venture, once you take into account the enormous costs of just getting a fab to make your chip?

I feel like the fabbing cost is so high, that at that scale, the CPU license fee is really nothing.

Correct me if I am wrong. This is coming from the mind of someone who knows next to nothing about how hardware is really made.
If you want to write a paper exploring some new computer architecture feature it's very nice to have a real chip with an actual existing toolchain to use as a starting point.

It's worth remembering that he was forced to shut it down because he designed it in a way that made it not just possible but inevitable that the DOJ would eventually get a court order for keys.

There is no transition in the investigative state machine for "data relevant to our investigation to which we are lawfully entitled exists and is available to us, BUT we will not retrieve it because doing so would be invasive to other members of the service". It's possible --- we could do some research --- that that transition exists in the state machines of no western government at all. Knowing that: if it's feasible to obtain information from a secure message service, eventually, the courts will mandate its retrieval.

As of 2014, there is a fundamental tradeoff that we know for a fact exists: you can design an encrypted mail service that is trivial for users to adopt, or you can design an encrypted mail service that meaningfully resists judicial power. You can't do both.

Presumably Uber is capable of identifying this suboptimal routing just as they can (and do, AFAIK) monitor the route your driver takes after you're picked up.

I'd hope that drivers who Uber estimates are N minutes away from pickup but consistently take N+5 to actually make the pickup are subject to penalties.

Thanks for your reply! Yes, the delay of gratification thing is what I've been practicing. Thinking "It will get better" has been keeping me going. However, after repeating that for a couple years one starts thinking "Well, when is it going to get better?"

Meditation seems like flossing to me: something that everyone says you should do more of, but, hardly anyone does it. It seems like a good idea that I will try again. I wonder: do you practice regularly, and, does it work for you?

I haven't played with it yet, no, but I work close to the bottom of the stack (in the nitty gritty bits of virtualization stuff); modern Linux kernels all look more or less the same from way down here :)

The Periodic Table of Web Design Process (infographic)
Take my advice with a grain of salt as I play armchair analyst.

Structurally, you're in a race for eyeballs and burning cash along the way. Sites like these can not be monetized easily until you have rapid growth and a large, active user base. Are you ready to burn a lot of cash? Do you have the clout to raise several rounds until you get to some sort of critical mass?

Sites like these monetize through two methods: advertising or product referrals. Even with millions of pageviews / month, you are still only looking to support a handful of developers. Looking at product referrals, review Refer.ly (YC12), which realized the business model of product referrals doesn't back out until you've reached millions of users. Between where you start and that millions of users point is an uphill battle. Then, at that point, you're kind of chugging along at ramen profitability.

Pinterest and Wanelo have raised large rounds and have been burning cash since 2009 with no significant revenues to speak of (unless something has drastically changed in recent months).
I wanna know how this kind of experiment actually works.

> Joe: "All right. Hold my sign, I don't wanna lose it."

> TSA: "Likely story. FULL CAVITY SEARCH, FELLAS."

> Bill: "Hmm, that didn't work. Next up, flamethrowers. Hey Frank..."
The thing that makes me nervous about having that sort of business logic in the database is two-fold: first, finding people that can write good, clean SQL and document it so others can use it can be tricky; second, changing that logic means, effectively, more migrations.

The model of a SQL DB as dumb storage, while hardly making good use of all the (awesome!) functionality of query languages, seems to make it easier in production and in hiring.

That said, it is downright comical just how much mileage you can get from using functions or optimized queries instead of hoisting all that data up into the application layer and doing the work there.
Importance of Ongoing Information Security Training
I'm trying to skirt the term VPN a little with this. Not only does it refer as you say to tunnels into networks, but it's also become a confusing term to end users of late because of things like HideMyAss. "VPN... isn't that something you use to hide your traffic from your ISP?"

Of the converted users so far, the vast majority of them are distributed teams. It's a peer to peer virtual network, so it allows them to have an "office LAN without an office." There's a wide variety of reasons people might want that.

Nevertheless, I am getting the impression that that's a niche market, so I'm thinking about other directions I might go with this. The underlying engine is very powerful and versatile, so there are other markets I could potentially apply it to: SDN, p2p SDKs for software developers, etc. I'm starting a market research deep dive on this kind of thing.

I can't imagine that there are no larger niches for a networking engine that enables friction-free direct connectivity between any two devices, but I'm not completely sure what these niches are. I've got some hypotheses but I want to let the market research lead.

Yeah, well, you know, Americans are still human and, thus, when push comes to shove, the system only works right when good people are running it. To some extent, it doesn't matter what the actual rules are, if assholes are in charge, people get screwed even if the rules are awesome, and if good people are in charge, then, you know, the system tends to work okay even if it isn't the sharpest tool for the job.
