I'm curious to see what happens to Amazon FPS if these product based crowd-funding apps take off. We may be in for a bit of a Paypal style crackdown debacle.

I actually spoke with the Kickstarter guys back in 2009 when I was considering branching off their idea specifically for product based ideas, thinking that it could be "Amazon for stuff that doesn't exist yet".

We all agreed that the idea should happen, but Kickstarter didn't want to do it for two reasons:

1. Their goal is to help artists succeed. They're artists themselves, and the guy who started the site's been working on this for years. It means a lot to them to help the little one-man filmmakers.

2. The risk in having products that aren't delivered on time, in the same form as envisioned, or aren't even completed was just too high. They were terrified of having a backlash of backers who thought they were purchasing a product when in fact the transaction is structured as a donation.

The second one is what makes me worried. What happens if, worst case scenario, Pebble goes bankrupt without producing any items? Who takes the hit there? Is it Amazon, Pebble, Kickstarter, or the backers? It isn't clear yet because we haven't had a high-profile failure yet. But it's only a matter of time.

This could start a trend towards moving away from Kickstarter. So far, the more famous projects that have pursued funding from a similar model without using Kickstarter itself (e.g. Lockitron, App.net) have done so out of necessity â€" they weren't allowed to use the Kickstarter platform.

But if people keep succeeding without being hosted on Kickstarter itself, that 5% fee might look more and more unattractive to people starting large projects. How much value does being on Kickstarter really add to your project, and how much is simply due to the brilliant fundraising model?

This is how it should be. Most of the kickstarter projects get funded after doing lot of promotions and leveraging founders's own social network. Kickstarter taking % cut of the fund is completely unnecessary in many situations. They do provide some kind of project validation which is important in high-risk projects.

up_and_up 2 days ago  replies      
In my opinion, Meditation and Mindfullness are not the same thing.

Meditation is a state, where the mind is completely silent, the breath slows waaaay down, the heartbeat slows waaaay down. Slowly ever so slowly, some bliss starts to bubble up from within. It is the climax of one pointed attention. Few people who say they "meditate" are reaching that point since it requires years of sincere effort. In Yoga, meditation is known as Dhyana, or the state resulting from the mind becoming one pointed for 100 seconds. Samadhi, which is considered a state of deep bliss is considered reached when the mind becomes completely still for 1000 seconds.

Mindfullness, is the act of being more aware during daily activities. Like watching actions and interactions. There is a gradual tendency to modify behavior to being more calm, collected and centered which helps to go deeper when attempting to meditate. The mind is still active during mindfullness, but it is being directed or corrected as needed throughout the day.

Meditation helps to develop deeper Mindfullness and vice versa. Meditation is like taking a shower, whereas Mindfullness is avoiding rolling in the mud and getting dirty. It is important to keep in mind that Meditation is literally a state where the mind is free from thought and that all the "meditation practices and techniques" are just different paths of reaching that same place.

Wait. Wait wait wait.

Great. Yes. Impulse control is key. Delayed gratification is part of how we define higher intelligence.

Meditation has what do with this, exactly?

> How [does meditation help]? By increasing your capacity to resist distracting urges.

This entire article is predicated by this leap of faith, which as far as I can see has little to no justification besides, "Of course it does!"

> Meditation teaches us to resist the urge of that counterproductive follow through.

One cannot just say things over and over to make them true.

webwanderings 2 days ago  replies      
The misconception about meditation is that it requires one to give up everything and sit silently. This is not true in its entirety as it depends on how one interprets the word "meditation".

The meditation does not necessarily require you to give up one thing for the sake of another. The goal of the meditation is to "be in awareness" and you can achieve this same goal by being alert and aware with any activity your find yourself doing at any given moment. For example...

You are washing dishes but you are not really washing dishes because your mind is wandering with thoughts on what you need to do tonight at the place you need to visit. By the time your dishes are done, you have already planned for your future as your mind kept you busy with the thoughts of the future while you forgot what you were doing in the present (which is, washing dishes, which you really didn't).

The meditation is to be-in-present with whatever activity you do and love to do. If you had washed your dishes with full alertness and awareness, you would have achieved the same goal of meditation.

Let's go even further with another example.

You love to play music as your passion (or dance, or paint, or fill in the blank activity here) but you don't get enough opportunity in the day to do what you love to do more with passion. When you dance or sing or play music or run or exercise, you get the opportunity during that activity to forget yourself in the act (the subject merges into the object) and you become one with the reality, or you transcend that favorite activity by merging your self into it. That moment of transcendence is meditation, and you should find more opportunities to be in that meditation, in those moments.

Now, I am not suggesting that the type of meditation mentioned at the source is wrong or ineffective. What I am suggesting however is that people don't need to get stuck with one type of explanation of meditation because ultimately you can achieve the same goal by shifting the focus a bit.

What the author calls "impulses" the Buddha called sankhara, or reactivity. The ones the OP is talking about are minor reactions.

These reactions do indeed impede our progress, as when our actions are driven by reaction we are not fully aware of what's going on around us. I first recognized the practical implications of this playing billiards - when I would strike a ball and miss, I would feel slightly dejected, and neglect to analyze what I just did to learn from it. When I would strike a ball and make it, I would feel slightly elated, and neglect to understand what I just did to learn from it.

My game got a lot better when I started playing the game, fascinated but detached from outcomes. There are a remarkable number of ways to strike a ball wrong - and it is interesting to consider why, having learned the game sufficiently, one would ever strike the ball wrong. Where does the variation creep in? Why, if I examine a table and decide to put the cue ball "just so", can I not do that? The answer, of course, is that there is countless non-verbal data that your body is sending you on each stroke - feedback from your bridge hand, the hand on the cue, even your stance and the feel of the felt all factor into this.

If you are attached to the outcome, all of this goes out the window. There is nervousness, fear, and excitement instead of systematic understanding.

dkokelley 2 days ago 0 replies      
I think the author has an excellent point about training one's ability to resist urges. Urges are spontaneous. They don't necessarily fit with our work flow. In fact, they interrupt it. Maybe a good analogy is the Time Management Matrix by Eisenhower (and popularized in Steven Covey's '7 Habits' book). Urges almost always present themselves as urgent tasks, but they aren't always important.

I'm not sure I agree with the conclusion that meditation will make you more productive. The evidence presented reminds me of a scenario from The Office, where Michael defends Monday morning movies by claiming they are more productive the rest of the day. Of course the reason they are more productive is because they have to be in order to recover the time spent watching a movie!

Rather, I think people don't realize how much spare time there is that gets wasted. Tasks expand to fill the time allotted. It's possible that meditation can help you identify those wasteful activities (urges) and address them appropriately.

Oh, come on. Meditation is not the way to "exercise willpower muscle" (running is the way to do so).

Meditation is the way to learn that your flow of thoughts is not you, it is mere side-effect, a smoke from an engine, a screen-saver, or just idle-running.

Yes, the practice of meditation is beneficial for will-power and self-control, but it is not the goal.) Goal is realization that what you think you are, is just a running total of all previous conditioning, and the ''real you'' could be "seen" is in an instant between two thoughts.

Any good ''eastern'' teacher will tell you that.

What about comparative effectiveness? For example, if we did an experiment where we started subjects on the following regimes, which would have the greatest effects on impulse control:
1) Learning to program (assuming the subject is not already a coder
2) meditation
3) aerobic exercise

Then we would have to figure out ways to measure "impulse control."

Such a study would have a lot more credibility than the author's contention that "I control impulses while meditating; therefore, meditation makes me more productive."

One controls impulses during a wide variety of activities; the burden is on the pro-meditation crowd to provide evidence that meditation is an especially valuable form of practicing impulse control.

Some of you pointed out it's not easy to control/stop the mind, yes, that's very true, especially for some people. To solve that, I suggest to read Ekhart Tolle's The Power Of Now, I think it's the modern book that explains the orignal Zen in a easy-to-understand way.

I used to think/worry/imagine too much about the future, and thus missed every actual moment I was living in, and it made me unhappy. I was living like that since I was very young and until I read the book The Power Of Now. So I highly recommend it.

Happens to me all the time. I am working on a piece of code in the afternoon, and can't move forward or looking to identify a bug or optimizing some algorithm - wasting hours. After a meditation session I walk back to the computer screen, take a seat, and my hand clicks around the tabs, my fingers scroll around, my eye catches one obscure line of code which is EXACTLY where the problem sits. I had this happen so many times, it's a given by now. The article (and I am sure all who do meditate) shares the same kind of experience.

idoruby 2 days ago 0 replies      
I have been meditating for forty years. For thirty nine years I did transcendental meditation (TM)as taught by Maharishi Mahesh Yogi. I sat for 20 minutes twice a day without fail.

Last year I switched to Vipassana not because I was displeased with TM but just for a change and because the Goenka community seems to be very professional. I have been sitting in this new way one hour a day for a year now. I am not as regular because Vipassana requires more arrangement than TM. I am satisfied with my practice and can see a path to grow in this community for the rest of my life.

I am not sorry that I have spent so much time meditating. It changed my life. Before I began meditating I was aware of a certain pervasive incompleteness. I am a programmer and I love programming and I have been married for forty seven years and love my wife. But these satisfactions were not enough. My meditation practice did not materially change my life but it has given me a sense of centeredness. I am in a quiet way more fulfilled.

My experience was that TM was a very practical choice. I paid $75 to be initiated and found the TM community meet my needs for companionship on my path. Community is important to support a meditative practice. The actual practice is practical to do in our busy lives. If you are too busy to take two twenty minute periods each day for your personal readjustment then you are too busy and you need to readjust your life pattern. If you do not realize the imbalance in your life, probably meditation is not for you. Don't waste your time. Perhaps later.

YMMV, nowadays it cost $2k+ to learn TM. It is a good deal at this cost at least the benefits in my life exceed almost any amount of money. But without my experience I would never understand that. It is a chicken and egg problem.

OTOH, the TM community has changed and I am not sure I would be served by the Post Mahrishi community. In my case, as a long term meditator the difficulties with the community don't really affect me. Although I did consider the quality of the Goenka to support me in future.

So the choice of TM is a possibility for a newby. One caution, I knew many poeple who started TM and did not continue. So you are risking $2k+.

Vipassana is different. The technique requires more training and a greater daily investment. I sit for an hour a day. But Goenka suggests a minimum of two hours a day. And most practioners do at least one ten day retreat a year. I find this a bit much. But given that I am retired it is easily feasable. It merely a matter of commitment for me. A midlife married programmer will find this a greater challenge.

The introduction to Goenka's technique is charming. You do a ten day retreat at no cost to you. Their story is that adopting this practice is a serious matter. You learn the technique and then practice ten hours a day for ten days. For this learning period you live on the charity of others like a Budhist monk. Since this technique is a way of living that extends beyond just sitting, you need time to get into it.

I don't know how to tell which is most appropriate for you. I can just say it works for me. But I can say one thing for certain. Meditation is a practice that must be done everyday. Don't bother if you are not ready to commit to a regular practice. The benefits of meditation can not be explained. It is an experience and all that a teacher can do is give the experience and show you how to protect it. The rest is up to you.

I will say that meditation and psychotherapy are not mutually exclusive. For more than twelve years during the last forty I have been in therapy.

My final thought is that if you have a sense that your experience of life seems not quite complete, meditation can work to give you greater experience of connection.

"And you will have experience that proves to you that the urge is only a suggestion. You are in control."

This is the most interesting part to me. Don't we always act on the urge that is strongest at the moment? If I decide to continue to meditate even though I have an urge to stop, doesn't that just mean that the urge to continue happened to be stronger than the urge to stop? Did I really get to choose which of those urges was strongest at that moment? Of course, this gets into questions of free will, which has been discussed on HN before. But when I meditate, it becomes very clear that I am definitely not in control of my thoughts, feelings, and urges. I see that I have multiple, competing urges at any given moment and that I don't control which urge emerges as the victor and compels me to act.

I believe this acts as some negative feedback for the control freak self inside me. Every time I exert unnecessary control it becomes uncomfortable.

Meditating long enough may show me that the mind will wander in its own ways regardless of what I maybe doing at the moment, and its best for me to let it wander on its own ways and focus on what I am doing. Thus helping me understand that all the thoughts about ego, and judgements is just come process on the sidelines, and different from the core of me, the core that is focused on what I am doing.

This is the impression I have of where meditation is taking me.

Meditation is an inexpensive and natural alternative to the other two, it's been around for thousands of years and there are no negative side effects.

On the one hand I'm very excited by this; I see Marco as an interesting writer/speaker, when it comes to iOS development or when he geeks out about whatever gear he's recently bought. I also expect him to be a great editor, so I'd gladly pay money for a magazine put together by him.

But on the other hand...I'm really wondering why this needs to be an iOS app. Written content is perfect for publishing on the web, I really don't think you'll be running into any speed issues when you release this as a web magazine. And even if you would, why not make the content available both native and on the web?

I'm aware that Marco is an iOS developer, and that a lot of his readers (myself included) will have iOS devices, but for the sake of the open web I'm still slightly disappointed.

It publishes four articles every two weeks for $1.99 per month with a 7-day free trial.

If I get a 7-day trial, how do I know that those 7 days will coincide with the 14 day article release cycle? This doesn't line up, as though it were designed to be confusing.

That sentence is worded strangely - talking about a future project you're organizing as though it's an object of someone else's which already exists. It sounds impersonal and odd. How about:

"The Magazine will publish eight articles per month at a price of $1.99, and we offer a one week free trial."

First - this is easily, beyond a shadow of a doubt, one the best online Magazine App for the iPad. It's ironic how Time, New Yorker, Popular Mechanics, National Geographic - all offer such horrible experiences that I've deleted them from my iPad. Only NYT and "The Economist" aren't totally crappy (Though neither of them download in that background on my iOS 6 iPad 3... Grrr - But I bet Marco's App supports background downloading.)

Second - The article on Volatiles and Stables was worth an entire years subscription by itself. Marco made it easy for us to copy/paste the text - didn't trap the content like all those crappy magazine systems normally do. I've been madly copying that article and forwarding it to everyone in the company, with a prominent link to "The Magazine".

I'm guessing that He'll get at least 10 direct new subscriptions through me alone. WHo knows how many indirect subscriptions...

Maybe there's a market for magazine type media. It seems so backwards and nostalgic. Print imposed restrictions on size, format, timelyness, access, single voice (no comments), among others. The description of "The Magazine" sounds like what HN or Reddit already is.

I've just been looking through the most popular Newsstand apps, and it suddenly occurred to me what's wrong with it: all the thumbnails are of print magazine covers, and they're all too small to read! If that doesn't scream "doing it wrong" I don't know what does.

The cover's meant to advertise the issue and make me want to buy it and I can't even read it. Why does Newsstand not have a "In this issue" tab when you preview the app? Why do I have to buy the whole issue instead of just an article? Why can't I have a central list of articles, that I can search, and favourite and share? The Newsstand API isn't aggressive enough. It needs to bring these publications into the future before we lose them.

Traditional print publications, which are producing quality journalism, need to adapt to new technology and release something like what Marco's doing here instead of trying to cram their paper format into an app with all the cruft that that entails.

I had an experience very similar to Brennan's recently. Appointment Reminder, the SaaS which I wish was the center of gravity of my business at the moment, is profitable but not profitable enough to hire the folks and buy the things that I want to accelerate growth of it.

So I have been supporting it by consulting, but when I'm consulting I'm not selling Appointment Reminder accounts, and consulting is always more distracting than I expect it to be. (You think I would realize this after two years of it, but I persistently underestimate how much time it takes to e.g. prospect for new clients, negotiate/schedule engagements, travel to them, and deal with follow-up stuff like invoices.)

The traditional option for scaling a software business with a working product and actual customers is to take investment, but that's another ball of wax. There's fairly attractive options in angel investing these days, but taking any outside money would have an outsized effect on the character of my business at the moment, and I'm not ready to pull that trigger yet. Also, like consulting, raising an investment round is a very distracting event -- it basically commits you to months of doing near no productive work. (And unlike consulting, taking investment causes time debt which is impossible to discharge until you exit your business: you're now committed to keeping those investors happy and in the loop for, well, forever in business terms.)

But, having seen a lot of smart software companies do side projects (37signals was a big fan of it, and Amy Hoy and company have quite a bit of success) I decided to try my hand at it once and see how it went. So I started packaging one of my most-commonly-a-win consulting offerings as an online course, and decided to experiment with it once. (And, like Brennan says and like everybody in the space will tell you, I started by making an email list and sending them lots of free stuff they enjoyed which further burnished my credibility on the subject.)

The experiment was very successful: my customers seem to have liked what I produced, many of them have actually used it to positive effect in their business, and it raised a significant amount of money. (I'll probably blog in detail about it later).

An unanticipated side effect was, because of the topic I picked for my video course, I actually sat down and took all my own advice for a change (AR had an email strategy which I would have never let fly at a consulting client simply because I shipped the minimum necessary and never revisited that decision), and that ended up working out very well.

So, basically, yes: confirmation from someone else, this does work and it is perfectly compatible with running a software business.

Let me present another view why I dislike this kind of selling. I think this author sells a story of how they got rich and how you also can get rich (and how you can do this easily) It's a common scheme and I think the only people that are getting rich by this are the people that are selling this kind of knowledge.

The problem (at least based on my experience) is that building anything successful takes a huge amounts of dedication and effort -- there's also a large margin for failure. It's simply not something that's easy to reproduce and you probably won't make five-figures a month by selling things to a mailing list. Or create a 30x500 product and instantly be your own boss. And sure, there are some that are going to succeed at this (and great for them!), but presenting this like anybody will get rich by just following a scheme rings off alarm clocks, especially when this kind of knowledge is sold at a high cost.

But how would I shake the feeling that these exist as part of the marketing scheme that the entrepreneurs engage in. These courses are not exactly cheap, but you know...

I don't mean to pick on OP, but I'm always a little surprised at how some authors can make money, by writing about how to make money. When in fact, the way they made money was selling books about it, not necessarily by the advice found in their books.

I personally don't feel qualified to write about how to build a successful business, because I feel my business isn't satisfactorily large or successful enough. Though I'm pretty sure I could write about it. I guess I'm surprised to see peers doing this as a means to become successful and raise money. It's almost like a self fulfilling prophecy.

Awesome post. I'm a huge fan of Brennan's ebook (we're about to do a discounted promotion of it to our 7500-developer-strong mailing list at http://21times.org) and it's already paid for itself hundreds of times over for me.

That said, the most exciting thing out of all the items he's making money from (consulting, ebook, workshop, and planscope) is planscope, because of that steady climb in monthly recurring revenue. Give it a couple years and that will dwarf everything else he's doing, and give him a nice platform from which to still bring in spikes of cash from info-products or workshops.

I'm starting to wonder if I should have ponied up the cash for Amy Hoy's 30x500 course (I believe Brennan is a graduate). Speaking of which, Amy is another poster child for this approach of SaaS + info products.

The presence or absence of the eater indicates whether the cell should be on in the next meta-generation.

These gliders then collide into beehives, which are restored by a passing LWSS in Brice's elegant honeybit reaction.

I think GoL unit cells http://www.conwaylife.com/wiki/Unit_cell like this demonstrate an important point. That there's certain limitations to our knowledge of reality.

Imagine an intelligent being in a GoL board, made of a huge pattern of cells (just like we're made of a huge number of atoms).

Even though when we look at a GoL board, we know it's made up of cells and that everything operates according to a fixed number of rules, this intelligent being wouldn't just be able to know this. It's perceptual system would be made of these elements (perhaps it somehow uses spaceships to find out about what is out there). Remember that you can't just "see" reality - you need inputs and to infer what's out there on the basis of them. The sort of view of its reality it could infer would be much more coarsely grained than at the level of individual cells, just as our unaided view of reality is much more coarsely grained than the level of individual atoms.

That intelligent GoL being could observe the way things behave and, on the basis of this, theorise the GoL rules - that everything was a bunch of cells, and that if there's an empty cell and it has three neighbours then that cell will be 'on' in the next moment, and so forth.

And if it existed in a 'standard' Game of Life board, it would have theorised correctly. But if it lived in a Game of Life board where each of the cells it has posited is actually one of these unit cells like in the linked page, then there would be a deeper reality than it realises (and of course there could be 'deeper levels' within that).

There's no way that GoL being could tell.

I wish more people would contribute information on using Flask at a larger scale. Everyone and their brother has written a basic tutorial outlining how to get up and running with Flask. This is a GREAT post and I do not want to demean it ... however I think that a lot of this can be gleaned from following along with the docs and experimenting with Flask in general.

I'd really love to see/hear some stories of others using Flask at a slightly larger scale. For example ... did your startup build their REST API in Flask? Sure, people say it's possible and outline a basic hello-world style REST app ... but in my experience it became a pain in the ass very quick. Primarily because no structure is enforced.

After being a Python dev for a long time, building quite a few big Django apps and a handful of tiny Flask apps I have finally jumped ship to Rails. I spent a week experimenting with various Pythonic combinations. Ultimately I had to ask myself ... "Why am I doing this? What the hell am I wasting my time with this lightweight framework?" I've built my current REST API in Rails and would not have it any other way. It's been tremendously efficient and performs great on my little Linode in London + PostgreSQL.

A good tutorial, but it was missing any mention of blueprints, which are essential to building a Flask site larger than a few endpoints. Blueprints also allow you to reuse components across multiple apps, or as releasing a set of endpoints as open source libraries that can be easily plugged into other apps.

Edit: adding a link to Blueprints in the Flask docs: http://flask.pocoo.org/docs/blueprints/

Since you're already using backbone.js why not plug in CSRF protection with Flask-SeaSurf?

If you use this backbone.js change then CSRF is practically invisible:

Also, if building an api with Flask make sure you use blueprints with a url prefix so your api routes become relative, which means less typing:

I know Java is verbose but the tooling is good. Just put you war(a pre-defined structure) in Tomcat webapps dir and your good to go with a fairly scalable web site. I was so surprised it wasn't that easy for Python. I think it stems out that Python is more of systemish kinda ecosystem.

I'll pipe up for Impro. One of my favorite books. Well, the first half is â€" it's a meditation on life and the universe as much as it is about theater, and it changed my mind in some cool ways. It's useful for anyone doing creative work, especially collaborative creative work, definitely including programmers. It's also very funny. The second half is about mask work and trance, which I was expecting to be fascinating, but it fell short of the sparkling magic of the first half. The material isn't as generally accessible and probably depends more on knowing how they use masks in production. Johnstone says that the masks have their own personalities, which actors take on when they wear them, and that's probably why he relies on them so much. His tastes in theater run away from personal expression toward simple universals. He's always telling actors to be more boring, and that the worst thing you can do is try to be interesting or clever.

Johnstone lives in my town in Western Canada. I ran into him in Safeway once. He's very tall and his eyes go in two different directions so he looks down at you rather quizzically from two different angles with his head tilted like a bird. I told him I loved his book, and he grunted "Good" and turned around and walked away. A few paces later he yelled "I'm glad it's useful!" and then went out of sight.

He's probably a genius. He was well-known in the celebrated London theatre scene of the 1950s, but came to find it stifling because he couldn't try whatever ideas he wanted without worrying what somebody famous would think. Then he went to teach at some remote place on Vancouver Island and discovered that he could think and do whatever he wanted. He liked that so much that he got a position in my town and stayed there permanently, presumably because there was nobody there who mattered!

Undervaluing Wittgenstein isn't really consistent with what I've read in American philosophy at least. If you go by objective metrics (which would be the Moneyball approach), he consistently tops the citation counts, and beyond that, is considered central to many areas. Probably only Heidegger gives him a run for most broadly influential 20th-century philosopher (though it's hard to compare directly, because they've been influential on quite different groups).

He's been particularly influential on analytic philosophy via Saul Kripke, among other interpreters. In popularity contests, he routinely gets voted #1 most influential philosopher in polls of academic philosophers as well, e.g. in a 1999 poll of mostly UK/US academic philosophers (http://commonsenseatheism.com/wp-content/uploads/2011/02/Lac...) and in a Brian Leiter straw poll (http://leiterreports.typepad.com/blog/2009/03/so-who-is-the-...). The former one concludes that Philosophical Investigations is "the one crossover masterpiece in twentieth-century philosophy, appealing across diverse specializations and philosophical orientations".

An interesting question might be who is undervalued on those lists: is there someone halfway down, or not on the list at all, who should be near the top?

+1 for Drawing on the Right Side of the Brain. It's superb.

I'd add A Pattern Language to the list. It's actually been very appropriately valued by the programming community, but massively undervalued by its intended audience of architects and urban planners. Should've been the architecture and planning book of the 20th century; instead most design professionals have never heard of it. Their loss!

msluyter 23 hours ago 2 replies      
A lot of great books, but it's unclear to me that most of these are actually "undervalued." Check out the blurb on the back cover of Philosophical Investigations, for example:

Immediately upon its posthumous publication in 1953, Ludwig Wittgenstein's Philosophical Investigations was hailed as a masterpiece, and the ensuing years have confirmed this initial assessment. Today it is widely acknowledged to be the single most important philosophical work of the twentieth century.

Drawing on the Right Side of the Brain has had a huge impact. From Amazon: "Translated into more than seventeen languages, Drawing on the Right Side of the Brain is the world's most widely used drawing instruction book."

Same with The Inner Game of Tennis -- it was groundbreaking when it came out in 1972 and had a huge impact not just on tennis, or even sports generally, but on musicians, artists, performers, or anything with a critical mental game. Back when I was working on my music degree it was required reading.

Is it possible that the author thinks these books are undervalued simply because many of them were released a while ago (when he was young or not yet born) and thus they aren't currently being hyped and/or in the limelight? That, or perhaps they're simply not that popular within the author's social circle?

Operators and Things, a (supposed) first-person account of a schizophrenic who recovered from the condition and wrote about her experience. The second half of the book is where it really shines, since the author attempts to analyze her experience as a window into the inner workings of her cognition: how it broke down, what she experienced when it did, how it recovered itself, and what led to it. Since the author is anonymous, and talking about one's mind is very introspective, it's hard to take away real science from the book but I found it fascinating nonetheless. While I really dislike pseudoscientific explanations of brain functioning, after reading this I took up the idea that the conscious mind is more of a time-slice scheduler and message-passer than where the actual computation is done. So concentration is about controlling your unconscious indirectly, like training a puppy how to play fetch: you give it suggestions of what to do, and ignore it when it doesn't do that :).

I'm linking to the Amazon page, but IIRC the book is old enough to be in the public domain and there is a free text version somewhere.

The interesting thing about Money Ball was that Billy Beane pioneered an analytic model for evaluating the true value vs subjectively perceived value of players.

For me, the most undervalued book is The Art of Worldly Wisdom by Baltasar Gracian y Morales.

It's a small book of very condensed and timeless wisdom in the form of maxims, written very poetically. It's not a self-help book, the kind you might picture. (any book is self-help in some way).

Perusing 5-10 maxims a day about 5 years ago heavily influenced the way I live my life, and still defines my character today.

It's a good list for cherry-picking a couple reading ideas, but the amateur comments about philosophy weren't well-received by this individual.

> I find that it's thoroughly undervalued by philosophers

Doing okay so far...

>though, who see it as an arcane and eccentric work of little value

Not so sure about that...the timing for Wittgenstein's work might've been unfortunate, given that people were starting to become infatuated with existentialism around the same time. That was as more of a pop-culture phenomenon than an academic fad though.

>it's a difficult thing to read

Okay again...

>Ironically for a book ignored by most philosophers, it contains the answers to a lot of their questions, and the method for answering all of them.

Hrm, no. A lot of the questions concerning philosophy and the method for answering all of them?

I sincerely doubt any work that could described in such terms would be as obscure as he proposes. This borders on the illogic of conspiracy theorists believing they've found some secret truth.

6. ‘Principles‘ (pdf) by Ray Dalio.

Tried reading it. His life storey reads like an entrepreneur who started by trying to fit in (held several corporate jobs), failed (fired for insubordination) then started his own company.

The rest reads like a self-help book written by an amateur. Some gushing about physics and natural history (which a HBS graduate probably finds unfathomable and mysterious). Then some deep discussion of his own inner psyche; why do successful people assume its their own uniquness that made them succeed and not, for instance, market conditions or good advice?

Then I gave up. Is very wordy, very very wordy, and not many of the words worth slogging through. At least the part I saw.

You can find near good as new editions of older books on Abebooks, at very reasonable prices. I used it to get a great copy of SICP, and just now ordered a version of How To Win Friends And Influence People published during Dale Carnegie's life, as Paul Graham recommended.

I don't think a typical sampling of the HN crowd would be familiar with the work of J.D Salinger outside of Catcher and the Rye, but as someone who's loved these stories intensely since my mid-teens, I can't recommend them enough. In fact the mere mention of Seymour: An Introduction in the article sent shivers down my spine, reminding me of the amazing originality and artistry of this writer that I haven't experienced for several years now (I very rarely read fiction now). I won't bother summarizing the stories here, but if you have even a passing interest in zen, religion, literature or (at the risk of sounding pretentious) life itself then this is required reading in my book.

People, I've just made this little hack to show the location in a map:

$("body").append("<div id='Map' style='width: 500px; height: 500px; position: absolute; left: 100px; top: 800px;'></div>")

then (once openlayers.js is loaded), run this:

  CreateMap = function ()
{
var lat = 33.3405;
var lon = -103.7601;
var zoom = 14;
var fromProjection = new OpenLayers.Projection("EPSG:4326"); // Transform from WGS 1984
var toProjection = new OpenLayers.Projection("EPSG:900913"); // to Spherical Mercator Projection

map.addLayer(markers);

map.setCenter(position, zoom);
};

CreateMap();


setInterval(function()

var lat = parseFloat( $("#latitude").html());
var lon = parseFloat( $("#longitude").html());

var fromProjection = new OpenLayers.Projection("EPSG:4326"); // Transform from WGS 1984
var toProjection = new OpenLayers.Projection("EPSG:900913"); // to Spherical Mercator Projection

var position = new OpenLayers.LonLat(lon, lat).transform( fromProjection, toProjection);
marker = new OpenLayers.Marker(position);
markers.addMarker(marker);
map.setCenter(position, map.zoom);

},2000)


Now, at the bottom of the page, you have a map with a marker showing the current location.

Btw, it's not just microkernels. Any time you have "one overriding idea", and push your idea as a superior ideology, you're going to be wrong. Microkernels had one such ideology, there have been others. It's all BS. The fact is, reality is complicated, and not amenable to the "one large idea" model of problem solving. The only way that problems get solved in real life is with a lot of hard work on getting the details right. Not by some over-arching ideology that somehow magically makes things work.

Yes, well, Torvalds is here disputing one of the main drivers of science, the motive that brought us Newtonian physics, quantum mechanics, you know, the very things he depends on via his use of microprocessor technology.

If your "one overriding idea" is wrong, then certainly that'll get you into trouble, but as history demonstrates, they aren't always wrong. They are always hard to come up with, and often when you come up with them you face an uphill battle with people who want to maintain the status quo and who can't conceive of "one big idea." But eventually those ideas are the ones that cause tectonic shifts in human progress.

His reference to Edison is apt. It wasn't Edison who brought us the AC motor that literally revolutionized power distribution and the whole industrialized world. It was a man who thought big, who had "one overriding idea": Tesla.

His statements about instruction sets are interesting: basically that people get excited about low-level instructions that exploit details of processor architecture, but what would really improve performance are high-level instructions that allow software to defer to optimal implementations provided by the processor. Makes sense. Very little software can know the details of the processor architecture on which it will run, JITed code being a major exception.

I want to really re-iterate how great Junio Hamano has been as a git maintainer, and I haven't had to worry about git development for the last five years or so. Junio has been an exemplary maintainer, and shown great taste

Having listened in on the git developers mailing list for the last few years, occasionally getting involved, I can re-iterate how true this is.

Sure, git development uses some anachronistic-feeling conventions (like mailed patch-sets) but these all have reason behind them and exist because they work for the people who are working on git.

I don't know how many of the processes are held over from before Junio got involved, however both those processes and how Junio handles the entire thing are a great case study on how open source can be done. Some entry points for interested people:

" [...] I think that rotating storage is going the way of the dodo (or the tape). [...] The latencies of rotational storage are horrendous, and I personally refuse to use a machine that has those nasty platters of spinning rust in them. [...] "

Is this about SSD vs. HDD? Does he favor SSD over HDD for Desktops?

Personally, my 99% use time computer is a MacAir with 256 GB SDD, and I love how fast it is and that I don't have to worry about breaking a HDD. But having so little disk space is definitely a limitation to me. I would have expected, that Linus has a huge HDD in his desktop computer, maybe in combination with a SDD for speedup.

Apart from price, isn't lifetime still a huge problem for SSDs? I was expecting HDDs to die out for Laptops but to be around for a long time on desktops.

I think we need more open source projects that are not open to contribution from anyone. This may upset some people but will keep the bar for quality high. Linus' original work has been tarnished by too many eager but unqualified contributors.

If he had just chosen a small team, I think Linux could have been a real contender to BSD in terms of quality. It would have taken time to do, but they have had a loyal user base (of non-contributors) and demand from early on due to the legal problems with obtaining BSD and that is I think what has pushed Linux forward.

"A potentially simpler alternative is to let the application itself tell the scheduler that one of its processes is special. PostgreSQL could request that its dispatcher be allowed to run at the expense of one of its own workers, even if the normal scheduling algorithm would dictate otherwise."

I don't see how this is so bad, it seems like the best solution too me. If you're writing a specialized high performance piece of software I feel like the application developer should be the one tasked with making sure the kernel knows certain things about it's application. It's pretty clear a project like postgres is doing all sorts of tricks and optimizations already, I don't see how this would be any more or less burdensome.

Overall I feel like it's a fair trade-off to have kernel be told specific things by the application so it can make the better scheduling decisions vs it having to guess and potentially make poor decisions at the expense of most common applications.

There's been too much effort wasted trying to find the one-size-fits-all perfect CPU scheduler for all system rules. For apps such as postgres that care enough about CPU scheduling to have written their own cpu scheduler, then it's not too much to ask the authors of such apps to make a few additional system calls to tell the kernel what type of scheduling is preferred for this app, rather then leave it all to the kernel to determine the perfect schedule for every running app.

acomjean 3 days ago 0 replies      
Interesting article, explains some of the tradeoffs that OSs make in scheduling.

OS scheduler optimizations are difficult. Often what makes the desktop nice and snappy makes background stuff slower. There are always trade-offs. Its also allows vendors to sell expensive versions of linux with different schedulers (redhat mrg...cough..) The Completely Fair Scheduler with its tree of process seems to work quite well though.

It seems like they were trying to optimize for specific hardware (the link to "scheduling domains" was interesting) when cpu swapping. (2 cores vs 2 sepearate cpus...)
good intentions, but..

Sometimes its useful to let users explicitly control which cpus processes can run on (process affinity). On the HPUX variant we used they let us set up groups of cpus and then map processes run on those cpu sets. you could also select scheduling of each process startup. It was a pain to get things running, but in the end it worked great. Manually selecting the wrong scheduler and process priority could result in some processes running terribly however.

I've never experimented with go, until now. I just ran all of the examples (found the mt=>fmt typo which I believe has been fixed). I think this is a great way to start, thank you for building it.

I have a few suggestions.

Make the code easily copyable. Under Chrome, at any rate, if you select the code you can't help but select your comments to the left of the code. I think that people running through the examples should type everything in line by line, but some people will prefer to copy and paste.

Also, it would be great to have some "where to go from here" links. I've run the examples, now I want to write some useful code. Where should I go next?

https://gobyexample.com/slices gives the impression that arrays and slices are independent things, which is not true. A slice cannot exist without an underlying array. A slice is a window view on an array, a reference to a part of an array. Multiple slices can provide different views on the same array. When you create a completely new slice you also create a new underlying array and the window size is initially the same as the size of the array.

I am not a hardware guy. Other than playing with n-in-one electronics kits as a kid I haven't ever touched it much. I recently needed to build a "sensor pod" (my name) for my ongoing 6-camera high altitude balloon project. I got everything working on a breadboard and needed to move it to a more permanent PCB. Enter Fritzing[0].

I fell in love with Fritzing pretty quickly. It has 3 mode. Breadboard, schematic, PCB. I was able to copy my physical breadboard layout over to the virtual one. From that, it basically gave me a schematic (what I wanted) and a PCB layout (not entirely useful for me). I had to touch up the routing and fix some lines that wanted to connect VCC straight to GND. I was able to figure it out pretty readily and fix it all and now have a working PCB[1].

All this is to say, if you're a noob, Fritzing is great. This (circuits.io) is probably geared at non-noobs, and I'm sure it's fine for them. I am not quite able to jump right into drawing a schematic, though. As such, I can't provide much of an opinion on it. :)

FYI: I'm a CS person who is learning about electronics and circuits. I started building radio and op-amp circuits, and have read that prototyping on breadboard doesn't work well. I tried going from schematic to directly soldering on a perf board and it ended in disaster. This tool seems exactly what I need ... though I could use it to figure out my perf board layout.

I like the ambition of this, and it has the potential to grow into something both useful and cash flow positive. Having a community of open schematics and layouts will be wonderful.

Does the layout editor support design rule settings/verification--things like clearance around traces and vias, via diameter, etc.?

An awesome feature would be a way to pull up a datasheet for a part by clicking on it in either the schematic or layout views. When I work on a project, I usually keep a paper binder of datasheets for quick reference. Having everything one or two clicks away would be great.

Using the Octopart API to build a BOM broken down by best vendor, per-part, would be cool too.

It wasn't clear when I tried using the site: Will it give me gerber files I can send to a fab? What about a completed board rendering a la OSH Park[1]?

Any plans to support components/footprints/libraries/whatever you want to call them from KiCAD or Eagle? Orcad? Altium?

This is a crappy solution, but it's the best cost/performance/simplicity tradeoff I've been able to come up with.

This is perhaps the first slide I've seen by Holman, but despite having seen what feels like a million slide decks this year, this one resonated to me like no other has.

In an older job, I was constantly battling my program manager's desire to have everybody "come in on time". It was a great offense to her if somebody came in so much as five minutes late. Despite being the managing developer for the team, and hence, ultimately responsible for all the engineering work that happened, I refused to care, so long as the work was getting done. I had a great team of talented guys that were always down to knock out a problem, whatever the problem was.

My boss wouldn't see the hours they put in working from home ("How do I know they're working if I can't see them!?!?"), or the hours they stayed late when the work wasn't done.

I tried the age old arguments "So long as the work is getting done..." or "They can come and go whenever they want so long as I'm meeting deadlines..." etc., but none of it flew. I regret not trying harder to change the culture before ultimately giving up and going somewhere that 'got it'. As a result, I have less responsibility, work from home, work more than I used to, and am happier to do so. I also can't imagine giving up the team that I have now for any reason, and I honestly think they feel similarly.

I usually poo-poo all over 'company culture' lectures, but this one completely hits the nail on the head as far as I'm concerned.

"I hate brogrammers" - but if I was asked to name a famous one, Zach be it. Excessive swearing in talks, "people on the internet are dicks", "OAuth will murder your children". If Zach Holman was holding a work barbecue, would people take their children?

I'm really curious if github's culture is the cause of their success or a result of it. I'm doubly curious if their bootstrapping was critical to this. My suspicion is that when outside investment arrives, the clock starts ticking, the pressure mounts on the founders, and this may result in a greater motivation to "manage" people's time, for fear of "wasting" time.

My favorite slide:

    Worry more about *building* the damn thing

Worry less *about* the damn thing

Many startups have a habit of being obsessed with themselves and their "culture" more than actually building the product.

There are so many things that are admirable and awe-inspiring about Github, and how they've gone about building their business. From my perspective, all of these things are a byproduct of one core value: building.

I think Github has nailed it in terms of culture. I've been trying to get my company to adopt the Github ways for a while and I can't wait to share this latest gem with everyone.

I do have some questions though. What is Github's structure like? Is it completely flat? Are there project managers? How do you 'manage' remote workers? I feel like there has to be a little structure to the chaos, or at least some techniques and tools that make things work smoothly, especially with a company that's growing so fast.

They were a big common lisp user apparently.

Google is normally very specific on the languages allowed for internal projects. A product/company acquisition with large assets written in common lisp would necessitate this becoming the "Google Common lisp style guide" rather than what it was most likely originally the "ITA Software" common lisp style guide. Speculation of course, but looks likely.

A very useful document that I mostly agree with.

One area of difference is in the conditionals. I never use WHEN or UNLESS for value; only for effect. And, I never write NIL as one of the values returned by IF; I always condense the expression to AND or OR. That is, I freely use AND and OR to return non-boolean values; this is a practice some deprecate, and indeed, I'm surprised not to find it explicitly mentioned here.

I do like to write certain kinds of iteration as tail-recursions, but I always use local functions (LABELS) when doing that; there's no implementation I use regularly that doesn't do tail-call optimization on local calls.

I've often thought that stylistic (as opposed to semantic) formatting rules should be enforced by pre/post commit scripts or nanny scripts.

This would be a huge pain with hard-to-parse languages like C++, but might work a lot better for C / ObjC / CL / Java.

Just put your braces wherever they make you feel special, and let the formatter sort it out.

Anyone do this?

This further reinforces how Yegge's recent "software political axis" rant was wildly inconsistent. His characterization of Clojure was "highly conservative" based in part on the best practices avoiding macros when possible, unlike "liberal" languages including Common Lisp.

Meanwhile in his own company's coding style for Common Lisp states very similar best practices regarding macros -- they should be used "sparingly and carefully", "You must never use a macro where a function will do.", etc. The whole macros section basically reads as a list of well thought out reasons against using macros when writing code that other people will have to maintain.

Yegge: "I trust that if you know anything about Lisp, your blood is basically boiling at this point." Really? Well then maybe the google CL team doesn't know lisp or otherwise are looking for novel ways to escalate their collective blood pressure.

I'm not sure I understand/agree the point about "iteration over recursion". One of my favorite aspects of Lisp is the recursive approach to writing functions. It's still possible to write recursive functions that don't rely on a specific compiler's optimization:

(defun sum (numbers)
(labels ((helper (todo ans)
(if (null todo)
ans
(helper (cdr todo) (+ ans (car todo))))))
(helper numbers 0)))

I hope that this is what the author meant with "iterative" approach, because it is recursive by most standards.

I'd really love to jump on EC2, but every time I run the numbers it doesn't add up for my usage.

I currently colocate all my servers and I wanted to figure out just how much it might cost to potentially switch over to EC2. After much digging and benchmarking, it seems that an single ECU is roughly equivalent to 350 to 400 points on PassMark. With this information and load metrics, it is pretty easy to determine what kind of ECUs I might need to switch over (as RAM and disk are pretty straight forward): http://www.cpubenchmark.net/cpu_list.php.

Came to the same conclusion as I did a few years ago. For my scenario (about a rack of servers, established business, 24/7 usage, capacity to handle for a 10-fold increase in usage (and much more within a 2 hour window))... I save roughly $170,000 over 3 years doing it all (server costs included). This is with 3-year reserved instances.

It should be noted that I build our servers from the ground up and do all the ops.

Very cool! This is useful for small deployments. We developed PlanForCloud.com to help with cost forecasting for big deployments, where you want to compare infrastructure options and cloud providers.

Also, don't forget that one of the key benefit of using the cloud is elasticity, and unless you model this, you won't get accurate estimates. We developed the notion of elasticity patterns[1] to let users do this, so you can say something like "my baseline S3 storage is 100GB, but every month this grows by 5% and in the Christmas it doubles".

What sort of clowns stored the credit card number in a cookie? Seriously? What a breathtakingly stupid show of total incompetence.

Was considering switching my personal account to Santander, have been looking to move away from Natwest for a while now. Natwest are a dismal failure of a bank to the extent I'm always happy to go out my way and dissuade people from associating with them in any way. I'll be writing Santander off my list for sure now. How on earth can you trust them after seeing this?

For a business who HAS to take security seriously, for a business with a LOT of resources, for a business who hold YOUR cash this is utterly pathetic and inexcusable on their part.

Leaving them might be a good idea for your personal security, unfortunately the UK is a little short of good banks. Would love to see someone shake up banking like Stripe has shaken up online payments.

I actually quit Santander(UK) because of their security policies. They essentially changed online banking so you had to give them a mobile number and then had to get a code from a text message they sent you to login.

My question to them was "what happens if I don't have a mobile phone?" and "What do I do when I am on holiday abroad?" and their responses were (paraphrasing) "You won't be able to use online banking at all in either of those cases."

In order to just get this response I got transferred between like four or five different customer service reps. So I quit my bank of like ten years and when I quit they didn't even care enough to ask my WHY I was quitting.

From a practical attack point of view:

1. As explained in the original email XSS attacks now lead CC exposure, very bad

2. If the cookies are not session cookies. It's horrible, then anyone who got access to that computer later can read the cookies and Credit Card. But also don't forget tons of websites still keeps auto-complete enabled!!!! in freaking CC fields.

3. If the cookies are not marked as "secure" (or issued over HTTPS) then it's totally messed up and invalidates PCI etc. directly. Now your credit card transmitted over HTTP.

4. Other than this even though it's rather pointless thing to do, there is not any more direct attack I can think of.

Put it this way, this is not worse than a XSS vulnerability in a website as an XSS can lead more serious issues directly.

Slightly on-topic. I have been trying with some banks in the UK trying to find the best online banking system and I am not happy with the results so far.

HSBC works quite well but the login system (with a RSA key) is annoying. I can accept it for actions like transfers but most times I just login to check my balance and transactions, requiring a token seems to much for me. Their design, even if not great, works.

MetroBank seems great from the outside but their system has some issues. First, to login you need your account number, a password and three digits from a 8 digits PIN. After logging in, you can do everything without any other measure. The systems fails to login most times unless you realise you can just click on the link in the error message and logged in you are. A friend told me to use the incognito mode in Chrome and it seems to fix this issue, probably with sessions. Their design is not the best. On the transactionspage you can only see 3 or 4 transactions on the screen at a time (without scrolling, that is).

I am waiting to try Santander (which I will avoid now) and Northern Rock.

Any good experiences?

I'm curious about responsible disclosure.

WhiteHat finds a security vulnerability. They tell the company. But, with banks, it's pretty hard to find the right person to tell. What steps should WhiteHat take to satisfy responsible disclosure? Just a printed letter to banks registered address is enough? (Banks, and everyone really, should have a "please use this address for responsible disclosure" - that would reassure me as a customer that they are taking security seriously).

But then, in England, we have a potential further step with the regulatory bodies. There's the ICO (information commissioner's office) who are overworked and will do nothing about this. And then there are the card companies who will, I'd have thought, be keen to protect their customers from fraud. Would responsible disclosure include a step to involve these third parties, if only to provide some clue pressure to the insecure site?

Santander ALSO stores your passwords in plaintext, or at least has access to them in that form.

My password used to include special characters, until a transfer to their new web interface year ago. After they did it,I could not log into my account - it kept telling me that my password was incorrect. So I rang them up,and a lady on the phone asked,if I had any special characters in my password. I said yes - and then she told me to try logging in without them,as the new system does not accept them and they were automatically stripped during the transition to new interface.

At first I was like - ok, at least now I can log into my account. But then it hit me - how the holy fuck could they remove special characters from my password???? The only way they could do that is if they had access to its plaintext, which is completely unacceptable.

I complained to Santander about it,only to receive a letter stating that they appreciate my concerns but their system is safe.

I've got all the correspondence with them if anybody wants to see.

For anyone interested, if you want to see the information it is storing then take the NewUniversalCookie and seperate it by the #'s then you can see two base64 strings which are easily decoded

The scary part is that the 'alias' id is actually one of the 2 passwords needed to log into the account. So in fact if someone had that and my card number all they would need is the 5 digit numerical code to log in
