If it's the Shelburne Falls center, I recall the sitting being closer to 14 hours per day with no timed sitting; i.e. you're meant to sit from break period to break period, basically 4+ hours at a stretch. Of course you could get up to go to the bathroom (read: escape), but some of the experienced students just sat straight through, impressive letting go.

That kind of practice is a heavy duty biological restructuring, no matter how many times the instructor says, "No I, no me", the knees certainly feel like they have nails drilled into them ;-)

The group energy carries you through, I suspect not many could do a 10 day Vipasana retreat alone.
You realize that's essentially what's already happening the article, right? Large databases companies like DRN are providing free or low cost ALPRs to repo men who submit a minimum number of records per month.

I'm not sure consummerizing it makes it much more terrifying, given the tremendous size these databases have already achieved.
That is the old one in Alpha. The new site looks way better and detailed. :-)
Just as a specific example, I had this experience with Bayes' Theorem <http://en.wikipedia.org/wiki/Bayes%27_theorem>. As an informal paper for my computer security class, we used Bayes' theorem to implement aimbot detection in a simple FPS. It sounds like a big, complicated theorem with a special name that some genius had to come up with and has complicated notation involving probabilities and logic symbols.

And then it's basically (paraphrasing with reckless abandon) just the probably of your event divided by the total probability space. Lots of words and jargon and theory given in countless papers and articles, and it pretty much just boils down to intuitive addition, multiplication, and division.

And our aimbot detector actually worked pretty damn well! Just gather some data points to determine probabilities, plug them into the simple formula, and it was always correct in our test cases.

Try instructions from the Theravada Buddhist tradition, or zazen. Though Buddhism itself is enormous and diverse, these traditions of meditation instruction are in themselves rational, unsuperstitious, and useful. I particularly recommend Gil Fronsdal's introductory series on http://audiodharma.org/ -- which comes from a U.S. tradition of secular mindfulness meditation inspired by Theravada and Zen.
Well put; a little quibble: these are the two notions of infinity that most interest set theorists, but there are many other notions of infinity in mathematics, e.g.,

1. Representation of geometric entities "at infinity" in, e.g., the point at infinity from the projective sphere that allows straight lines to be treated as circles;

2. Infinitesimals;

3. Game-theoretic constructions of infinite numbers, e.g., in Conway numbers. Incidentally, the set-theoretic cardinals are equivalent to a special case of these;

4. Definition of numbers as equivalence classes of functions under their speed of growth as they tend to infinity, e.g., Hardy's logarithmico-exponential functions. Incidentally, the computable set-theoretic ordinals are equivalent to a special case of these.
You misread the article. He is not recommending that students solve every exercise; he's recommending the exact opposite.

I created a presentation remote for a hackathon.

It's far from a "killer app" but it does solve a problem I've had (you don't need a second screen pointing towards the presenter at a conference, and you don't need a device in your hand to progress your slides during a talk)

Most of the apps released so far have been of the "because I can" genre. There's not a compelling reason to use them on Glass rather than your smartphone.

"Overpriced" - I'd like to see someone attempt to compete with LEGO on their terms. Mega Bloks don't cut it because they're not the same quality.

So build a new 'LEGO' company, build the bricks to the same quality standards as original LEGO does, and let's see if you can beat their price.

> Already, mapping technology can cause marital problems

No, affairs can cause marital problems. Technology just makes it easier to get caught This is not a vindication of the technology in question, but it can't be blamed for everything.

I can't help but think that cheating business travellers had it a lot easier before the advent of ubiquitous, near-free mobile long distance telephony made it easier for spouses to keep tabs on the travelling partner. That doesn't make telephony a cause of marital problems.
We use pretty aggressive compression on images at the moment, so yes. We need to start work on guessing the user's network speed so we can show higher quality images.

I've been lurking on Hacker news for some time, and I'd say it's pretty common for threads to be filled with this attitude. I'd say it's a tad bit more common in threads that somehow is Apple related (this is a mac only app).

Why would this be considered "an outright lie"? Does "speak out" always have to be attributed to negative opinions? This article wasn't perceived as negative towards Java in my eyes, but one could say that the respondents to the survey spoke out about their future intents and most desired features.
Twitch Launches A Smartphone SDK
A have wished I had Google Glass a few times when my infant child was doing something cute. It ruins the moment to go get a camera, or to fiddle with a smartphone. By the time you go get the camera, the baby has stopped doing the interesting thing, and is now wondering what you are doing. I once bought a camera based exclusively on 'time to first photo' (circa 2006) because of this issue.

Another app that I expect to see would be some sort of Robocop/Terminator display for law enforcement. I have been to the SHOT Show(1) in Las Vegas, and the number of toys available to LEO is surprisingly large. Things like guns that shoot around corners (uses camera), to small tank like things. Google glass combined with a camera on a weapon would be something likely to develop.

I think once someone like Oakley can integrate Glass into their eyewear make it less obvious that will change some things too. As it stands I have no particular desire for this piece of technology.

I've felt this is the case for a long time. A lot of people have a smooth experience in math for years until they hit their first serious discontinuity. That could happen anywhere: times tables, fraction arithmetic, two-step equations, geometric proofs, radicals, limits, or maybe even college math. The reaction is nearly universal though. The person thinks, "holy crap, I guess I'm actually not good at math", anxiety strikes, and they freeze up.

Some people find eventually find their way around this first road block, and future discontinuities in understanding become less stressful, and eventually understood to be a completely normal part the process.

But the usual experience is that a person's math confidence is blown and as the math truck barrels on ahead, they never catch up. They understandably accept the identity of not being "good at math".

What's missing in math pedagogy at most schools is a systematic way to deal with the discontinuities when they strike, especially that first time. We can prepare students to deal with that panic. The tough part is that the math teacher probably has 90 students on roster, but the discontinuity could hit pretty much any given lesson, for some given student.

I know so many people who have come back to intermediate math later in life and breezed through it, armed with intellectual confidence gained from other fields. They look back and wonder how they came to be so intimidated by math in their younger days. We've got to give younger people the tools and knowledge for overcoming this intimidation at a younger age. We've got to kill "I'm just not good at math".
Very nice! I have made one as well[1], it is based on Markdown and not nearly as fancy.

Why do people here sympathize with this movie? It starts out as an amusing corporate satire, but if you really follow the plot, it is disturbing on numerous levels:

- the consistent message provided by the hero, is that it's okay to be a cog in the machine
- the only save-the-day solution provided by the hero is to "follow instructions"
- all the creatives (the master builders) are captured and tortured
- Emmit saves the day by martyring himself in some bizarre Christian allegory where he ends up in the "real" world
- the psychopathic manager-type tyrant who rules the world and wants to freeze everyone is declared okay and special at the end
Placebos are highly underrated.
There are a dozen points here... The shallow bugs statement is true when there is a community that is large and with incredibly deep understanding; linux and posix is a great example, there is staggering depth of knowledge on those interfaces and behavior. Unfortunately there isn't wide and deep knowledge of tls architecture and implementation, there isn't even a lot of commonality across interfaces.

There is a social axiom that you and I don't know crypto and we should leave it to the experts, yet they need help too.

There is conventional c style and this function, while documented, does the opposite. I had to look at the code a couple times to see the bug, a lot of reviews could have missed it.

There is conventional c style and the whole failure chain cleanup mess, look at that code again, they've got their own data representation and free function that uses it to detect if memory is allocated, the free is private but the initialize is done inline. That stuff happens everywhere by many projects, I'm not saying its wrong but it leaves it open for easy bugs, one gaffed variable declaration potentially screws everything and you need to know the data structure even though you don't directly use it.

And I don't want to pile on gnutls, I think their intentions are good and this is a bug, but this looks fucking prime for unit testing...

There are a lot of variables to determine and measure a projects health, the whole community needs to step up in the quality department, there are lots of ways to contribute and despite the adage, more people should look at crypto.
I started off doing a combined maths and computer science degree.

With both computer science and maths you are chronically confused. The difference being with computer science it doesn't matter so much if you don't understand something, if you can get it to work you know you are on the right track. Maths is much more progressive, each proof builds on a previous one. So if you fail to understand one step you are screwed from that point on.

After the first year I realised I didn't actually enjoy being permanently confused and so I ditched the maths to focus on computers. I do regret this. It didn't take long at all before I forgot all that knowledge I had spent years sweating over.
> "Overpriced"

Legos are priced at what people are willing to pay for them. If they were overpriced they would not sell and there would be no Legos. Maybe you are suggesting that Legos should be cheaper because the material cost do not justify the prices you see, well again, Legos are priced at what they sell at and clearly people have voted with their wallets and have said that Legos are worth greater than the sum of their parts. It would be a disservice to Lego's investors to price them in accordance with the wishes of people who think everything should be accessible to everyone. For-profit companies should responsibly capture all the value they can.

I really, really want to say that I think this technology is a bad idea. But I don't.
I don't think that the technology is the problem here, as Digital Recognition said they are not _technically_ invading privacy since the license plates are available for everyone to see. And if you outlaw it, whats stopping a few crooks organizing their own underground data collection and selling the stuff on a black market? Rather, I'd prefer to see a different way of "licensing" cars. Maybe some kind of RFID chip that can only be read by law enforcement? I know its quite unlikely something like this will ever happen, but anyway.
I loath academic papers. Often I find I spend days or weeks deciphering mathematics in compsci papers only to find the underlying concept is intuitive and plain, but you're forced to learn it bottom up, constructing the authors original genius from the cryptic scrawlings they left in their paper... and you realise a couple of block diagrams and a few short paragraphs could have made the process a lot less frustrating.

It's like this all the time in math papers. It often seems in the end like the ideas themselves are fairly straightforward, and it shouldn't have taken that long to understand. I think, though, that if you actually sat down and tried to explain it in more intuitive terms, you'd find that you might not be able to. True, you could find a way to convey the general idea, but without the technical details, (1) while non-mathematicians may get a surface-level understanding faster, even mathematicians will not grasp the technical aspects, and (2) it will be very hard for anyone to extend your work or for anyone to apply it to another situation, so it will only be applied in the specific contexts that you explained it in.

Language isn't built to communicate math, so doing so effectively will be either difficult to understand or imprecise. Many people claim that it would be easy to explain deep math concepts with "a couple of block diagrams and a few short paragraphs"s, but I'd challenge them to write a textbook on abstract algebra, or topology, or something like that before they make that claim.

When Google Glass first was announced, I imagined a future where it would become more common to rent out access to one's vision. I imagined a service, called BuyMyEyes, that would set up per-minute or per-user fees that sellers could use to offer access to their line of sight to interested viewers. Then there could be a chatbox where the viewers input what the "eyes" should go look at next. In such a world, I could imagine a system where police departments send a notification: "The person 50 feet in from of you is a potential person of interest in an investigation. Keep him in your line of sight for 10 minutes and win a free iPad!"

Remarkably, the Lego Movie is PG. I used this as the excuse to keep my wife from taking the kids. I'm a huge fan of the toys, less so of the advertising. I used Legos as building blocks to teach the kids letters. They build trucks, castles, and learn to count with them. I've even been to Legoland, which is great for kids.

To the point of the original post, it's just the branding and consumerism that's over the top. I can't wait for them to replace all the Lego Movie ads at the bus stops and train stations.

Hi,

there is a real chance that your job as a programmer will be "automated" in the near future. This might happen because
1: due to globalization and internet a 7 year old from wherever can do your job for like half the price OR
2: computer will become better in understanding problems.

I think the second option is around for about 20 or 30 years. It all starts with AI (Artificial Intelligence). Actually, i don't see any major breaking news in this sector despite its becoming "hip" again.

A real automation for our developer minds is probably out of near future (+50 years). Its a developers mind to get a problem from a customer, understand what the customer wants, offer different solutions (future oriented, short term, secure solutions etc.) and finally solve the problem.

Was my answer corresponding to your question or did you meant something else with "automation of IT Jobs"?

Greets,

Chris

Sure, you got a point. (I've upvoted you.)

In the same time, Dropbox is more towards less savvy user and when you use Dropbox is more for the Cloud hosting than for its rsync capabilities.
>I could imagine a system where police departments send a notification: "The person 50 feet in from of you is a potential person of interest in an investigation. Keep him in your line of sight for 10 minutes and win a free iPad!"

I'd be surprised if it doesn't go like "The person 50 feet in from of you is a potential person of interest in an investigation. Keep him in your line of sight for 10 minutes or you'll be arrested for not collaborating with our investigation."
Group theory is a standard topic in a
college course, say, at the junior level,
in 'abstract algebra'. So, the other
topics typically are rings, fields,
vector spaces, maybe the construction of the
rationals and reals. The course might
also toss in a little on number theory.

Anyone with a ugrad pure math major is supposed
to know what a group is and the early, standard
theorems.

Group theory was used by E. Wigner for the
quantum mechanics of molecular spectroscopy so
that at times some chemistry students want to
know some of group theory and group representations.

My ugrad honors paper was on group theory.

I published a paper showing how a group of
measure preserving transformations could lead
to a statistical hypothesis test useful for
'zero-day' monitoring for anomalies in
server farms and networks.

Group theory pops up occasionally. Get
a good, standard text in abstract algebra
or two or three and spend a few evenings.
If you get to Sylow's theorem, you are likely
deep enough for starters. Group theory is
very clean, polished stuff and can be fun.
Go for it.
Cool concept, but there's no way it's happening with the current Glass optics. The screen is just too small, removed, and low quality.

It's all about priorities. If your life really depended on it I'd bet good money you'd find the time to do it.

I went to a 10 day Vipassana retreat last august and I'm really glad I did. Sure, I got cold feet and the usual fears: the fear of failure, the fear of not being man enough to last the full 10 days, you name it... In the end I chose to get past the fears and the excuses and just to it and I encourage you to do also. I was worried that I'd be in pain because of some gastritis I was doing treatment for at the time but they have been extremely supportive and they've provided me with extra food for dinner (everybody else just got fruits for dinner) so my stomach wouldn't chew on itself. I'm sure I've tried to make some other excuses for not going but they don't come to mind right now. I plan to go to other retreats too. After you do your first 10 day retreat you are considered an old student and can go to retreats just for a couple of days if you want.

I now know that leaving my comfort zone is one of the best things I can do for myself.
What's the best way to relearn math?
This issue that individual observations usually seen as benign become concerning when aggregated at computational scales is coming up in government surveillance as well. It is fairly uncontroversial that the police reading your license plate as they walk by your car isn't a 4th-amendment violation: it's not a "search" to view the exterior of a car parked on a public street. But is it still okay if the police start tracking the movements of all cars around the city using a network of license plate readers? Many people would be wary of that, but it's not clear what the difference in kind is or where a line could be drawn.

In the government case, the "mosaic theory of the 4th amendment" is an attempt to produce a new rule that certain aggregations of non-search data become searches when aggregated, so it may require a warrant to track you around the city with a network of license-plate readers, while it doesn't require a warrant to look at the exterior of your car normally. It's a bit fuzzy, though, and not clear it will survive (or be practical to administer). And it's not clear whether something analogous should or could be done for private collectors of data. And of course if it isn't, then that's an easy loophole for the government too: the government can just buy the data from the private data collectors. Under current law, at least, the government buying data lawfully collected by a private party who willingly sells it isn't considered a search, and doesn't require a warrant.
The verbosity of Java is because you have to take care of stupid low level details. All kinds of buffered readers, loops, internal class state juggling, etc. There is no support for first class functions, despite them tacking lambdas on awkwardly.
Unless there are COW mechanisms in place, simply pulling characters from /dev/{,u}random and scribbling over the original file should work well enough for the purpose of overwriting after the 10 second window.
