I have and loved it - it is responsible for my regular use of the word 'gumption.' But, now that you mention it, I should go back and read it again. When I first read it, I was much more technically oriented and have since shifted towards a focus on writing. This is largely what caused said quandary.

When you're working on technical problems, the question of value is relatively straight-forward: you are attempting to solve a problem by creating tools or applying existing ones. As a writer, it's a bit more nuanced. Moreover there's not a quick or easy way to measure that value.

If I hack up a script to grep a dataset, when it's done, I can toss the code and nobody has to know how ugly it is - the task is done. I cut an hour of work down to 30 seconds using 15 minutes of coding: saved time = obvious value.

If I rewrite the copy on my landing page, I may see an increase in conversions, but there's a strong chance that I timed that rewrite to coincide with a marketing push. Did my new landing page with a stronger call to action and a more approachable voice convince people to sign up? Did my popular friend give me some twitter love? Or did I change the copy to fit a new, more attractive design?

Basically, 'value' is an extremely elusive concept. I've asked a lot of people about it and the resulting conversation is pretty formulaic: it starts with a simple, poorly veiled abstraction of what the respondent does and, as I challenge it, it morphs into this maddeningly abstract compromise.

This response was inappropriately long, I realize, but it's obviously a topic that's been tugging on my brainstrings.
A friend of mine did something kinda similar. They might be somehow scraping/processing the twitter/facebook links. Ends up being pretty processor intensive.
It would appear they are doing some server side magic to determine which stuff shows up (hence the need for their own server):

"...Well, it has a set of algorithms that are looking for highly engaged items. You know, items that have lots of comments, likes, or retweets. It also has an algorithm that senses photography that’s been linked to from Facebook status messages and it lays those photos out."

Play AVI on iPhone 4
AVI is the audio-video interleave is a container introduced by Microsoft. Motion JPEG is a type of AVI compression, used mostly by digital cameras. While most downloaded AVI, which is ubiquitous for standard definition video content on the Internet, are encoded with XviD/Divx codec and there's no indication Apple is supporting such AVI.it won't let you play downloaded AVI movies on the iPhone 4.so you need to use this isksoft video converter for mac to convert to be iphone supported format.

You know, I really wanted to beat someone to the punch and create a canvas toy to do just that. Given two images of the same dimensions, render a bin-op of their pixels, where "bin-op" is a boolean operation.

Fucked if I know what I am doing wrong, but I just can't modify the data array of the canvas element's graphics context.imageData.

var canvas, ctx;
var image1, image2;
var img_data1, img_data2;

function load_images () {
image1 = document.getElementById("image1");
image2= document.getElementById("image2");
}

function load() {
load_images();

canvas = document.getElementById("cv");
canvas.height = Math.max(image1.height, image2.height);
canvas.width = Math.max(image1.width, image2.width);
ctx = canvas.getContext("2d");

var tmp_canvas = document.createElement('CANVAS');
tmp_canvas.height = canvas.height;
tmp_canvas.width = canvas.width;
var tmp_ctx = tmp_canvas.getContext("2d");

img_data1 = ctx.getImageData(0, 0, canvas.width, canvas.height);
img_data2 = tmp_ctx.getImageData(0, 0, canvas.width, canvas.height);
ctx.drawImage(image1, 0, 0);

// seems like I just can't modify the array data and see it updated on the display
for(var i = 0; i <= img_data1.width; i++) {
for (var j = 0; j <= img_data1.height; j++) {
var idx = 4 * (j * img_data1.width + i);
img_data1.data[idx] = 0;
img_data1.data[idx+1] = 0;
img_data1.data[idx+2] = 0;
img_data1.data[idx+3] = 0;
}
}
}
Yes, you could hold him to such standards. On the other hand, he has to do some PR for getting his goals -- does it matter, if he does his own PR or hires an agency?

My personal definitions are backwards from that: I just define `mispricing' as anything that allows arbitrage. (Especially risk-less arbitrage. But you can -- in theory -- make almost all arbitrage as risk-less as you want, with the right derivatives.)

A nice tutorial. By the way, Monads are an interesting pattern. But far from the only type class that useful in Haskell. The Typeclassopidea (in http://www.haskell.org/sitewiki/images/8/85/TMR-Issue13.pdf) gives a nice overview. I find Arrows especially interesting at the moment, but that probably because I already know Monads, Functors and pointed Functors quite well.

Conal Elliott has an interesting blog post talking showing how to use Arrows as semantic editor combinators (http://conal.net/blog/posts/semantic-editor-combinators/). It's enough to get you started on arrows with a useful application. (Of course, as with Monads, arrows are much more than this one application. But seeing one concrete application is a good start for your imagination.)

I tend to write down ideas in the "someday" list, or in the project list if it's a project. It just won't get a due date, nor tagged with "next". Every week I try to go through the list, and remove ideas that I don't think are worth following up.

I also keep a research wiki where I dump links and ideas, but I haven't gone back there for a while. I think it's largely something useful to track back the genesis of an idea, and remember why you thought of it in the first place. I often remember the solutions to problems I have forgot!

I use notecards - I keep a stack of blanks in my bag. If they're not particularly actionable, they go up on my blog for such things(http://mohrslaws.com/Lifein3x5), otherwise, they go in the to-do pocket. If they don't fit in either, I fold them into an origami frog, draw a funny face on it and leave it by the wayside. (http://tweetphoto.com/12387364) - This is also the format I use for my business cards.

If I ever find myself wanting for something to do or ponder, I just go to the to-do pile and browse.

I like the physical aspect of this system. To me, the important thing here is getting the ideas the hell out of my head - it gets kinda crazy in there, it's no place for a delicate thing like an idea. Plus having a big, unsorted stack makes them more interesting to browse.

Machine learning and Artificial Intelligence are making their way in trading and investment.

Strongly recommend you "The Elements of Statistical Learning: Data Mining, Inference and Prediction" by Hastie, Tibshirani and Friedman.

One of the technologies our company develops is called Alimp. This is intelligent software for automatic creation and testing of robust trading systems powered by advanced A.I.

The idea is to run Darwinian process of trading systems evolution. Alimp uses combinatorial intelligence to generate 500 000 trading systems candidates per day. Then research group picks up the best survivals to package (to add money management, position sizing, risk control, etc.) and to test.

Maybe our white paper will be of some use to you. You can read it here: http://disfa.com/downloads/Technical%20paper_ICAI08.pdf

Good luck in your endeavors!

Yep, hi, I'm the chief everything of Freckle. ;) (Except chief code monkey.)

So, pricing wise, we had a particular strategy and we add very particular, measurable value. The value for a team is honestly more than double the value for an individual because value increases directly with the number of people who track time.

I've actually hired a pricing consultant to talk about whether our pricing strategy (the chunking of user seats, the size of price increases) is the best for us.

Til that process is wrapped up, it's a bit hard to weigh in!

I will say that we priced our base plan higher than our "competitors", based on the difference between Basecamp and Basecamp With Time Tracking, although it looks now like our "competitors" have increased their prices as well.

(I say "competitors" because we really serve different markets.)

Also: we have as many Solo account members as all other paid accounts combined.

We're not hurting for money either ;) and growing about 20% month over month since I've started serious promotion strategies.

Hope this helps!

We can easily choose to ignore money and enjoy the simple pleasures.
I love GTD for all thing I need to get done but ideas IMHO don't really fit that "mantra".

I keep track of my ideas in a Moleskine Notebook. They are available in many formats and are able to whitstand almost anything. What I love about having a small "book" of ideas is that I can take them anywhere, scrible and brainstorm around my ideas etc. All this is possible without being restricted by a given format. Its also very easy to browse through ideas if you store them this way and I found it very easy to find ideas again once you remember you had some solution or approach to something.

If I by chance don't have my Moleskine with me I email myself the idea and as soon as I get home or start emptying my mailbox the idea gets transfered into the notebook.
haha. indeed. And allowing users to tether their iphone is far and away less damaging than creating a worm that infects sendmail.
How to set up a free co.cc url with free hosting (easy)
> One reason for this is that the judge is going to be weighing on the one hand this guy's thousand dollar investment, and on the other hand, everybody else's millions of dollars of investment, and asking if harming the millions of dollars of investment is proper on behalf of the guy who put in $1k.

Yeah, rules only apply to the little guys. Contracts should only benefit the big, rich organizations.
Post-neolithic age humans are easily the most social animal in existence!!! Any human that does not grow or hunt their own food is a social animal whose existence depends on a large interacting society. Even monks in remote monastaries rely on support from churches who need priests with good communication skills to put the fear of god into as many people as possible to exist.

"Regardless, in the end a judge is going to be asked if a $1,000 passive investment really should be worth billions of dollars in 6 years. The answer to that question in our country is 'no.'"

I would hope that in this country, if the investment is backed by the proper legal documents, that the answer would be yes. that whole rule of law thing.

Otherwise, are you saying that if one makes an angel investment of $1K for 10% of a company, that a judge should back other larger deeper-pocketed investors against the angel primarily because the judge would ask "if harming the millions of dollars of investment is proper on behalf of the guy who put in $1k."?
Yep acronyms are a PITA :)

The whole point of the GPL is so people have the freedom to tinker with the source code (this has been said by Stallman many times). If we had no copyright laws, there would be nothing stopping people from releasing binaries only. The difference would be that you could share the copyrighted works with anybody.

Would this really benefit the community?

The flipside is also that everyone would be free to reverse-engineer everything, which is a pretty powerful good, but I see your point and I agree with it, it's probably better to have copyright than to not have it.

Then again, you could of course have a completely different society where all software must be available in source form by law, but I have a hard time seeing that happen anywhere. :-)

Why can't they just lease Ka (or maybe Ku) band transponders, at least to start? That replaces $1b capex with somewhat-higher opex.
I once had to try and salvage something useful from a huge J2EE application where the development team were obviously as they say "taking the p*ss".

At one point I counted 23 layers of abstraction between the fairly simple JSP page through EJBs and a connector to eventually make a simple SOAP call to get the data to go on the page. Everyone of those layers had an interface, a factory and an implementation....
Yes, but a lot of them don't find it necessary to openly talk about their balance sheets.

I'm sure Wufoo and the Weeblies are profitable. Grapevine says that MixPanel is profitable already. AirBnb came out early in the press and said they were ramen profitable and then talked about the advantages of being "pizza" profitable shortly thereafter. I'd be very suprised if Dropbox wasn't making decent money, although they may be focused on scaling rather than maximizing profit. I could be wrong, but at the work at a startup event, a couple of companies said that they were profitable already. Listia, maybe? Don't quote me on this.

From talking to YC founders, there's a pretty heavy emphasis to getting ramen profitable as soon as possible to gain leverage in fund raising negotiations. Starving founders tend to give away more equity and get worse terms than founders that can feed themselves and pay the rent.

p.s. Nice to talk to you, Zack. How are things?

Sigh . . .

I get that CPS doesn't always do the best job, and plenty of the people that work there are on a power trip and got into social work because they like telling other people what to do. The world would certainly be a better place if they were able to do their job better and if some of their officers were more courteous.

But as you probably know, working for CPS is an incredibly difficult job. It's very demanding on your time, it's immensely stressful emotionally, everyone hates you, and it can put you in physical danger (you often have to be accompanied by a police officer). Unsurprisingly, in many places they have trouble finding enough qualified applications to fill the necessary positions. I know that I sure as hell wouldn't want to do that job.

I guess I just get tired of the vitriol directed their direction as if the world would be a better place if CPS wasn't around, or as if they intentionally make life hard on people just because, or as if they're somehow more lenient on poor people. Your additional comment there is, in my experience, pretty wildly off-base: my wife is a social worker who works with plenty of poor clients who have had children taken away and never managed to get them back because they're unable to support them financially or have ongoing drug or alcohol problems. The kids are put in group or foster homes basically permanently, not sent back to their parents. And it's not like the "poor crackheads," as you so respectfully put it, don't care: they care just as much as anyone else does.

What I'd like to see is some more level-headed analysis of what the "false positive" or "false negative" rates are. For every family innocently harrassed, how many families are quickly cleared of any wrongdoing and how many children are removed from abusive situations? It makes a big difference if 60% of the claims CPS investigates result in putting an innocent family through hell or if 1% of the investigations do.

Again . . . would the world be better if CPS was able to do a better job? Sure. Would the world be a better place if we reverted back to treating children like property with no rights and allowing parents complete free rein over their children? No.
Apple isn't going to use the kill switch on this, just like they didn't on the last tethering app. They simply remove the apps from the store much like they've removed other apps from the store that violated a policy (the commodore emulator). The kill switch, i.e. removing something from phones would be for extreme cases where actual harm is being done (virus propagating out of control, etc.). They aren't going to use it without having a _very_ good reason as it will no doubt be highly scrutinized.

Monavie review is going to be one of the most unique reviews you’re going to find about the monavee company online.
When I was teaching myself web programming, I wrote a blog (in PHP), then an image gallery (in PHP), then somehow I landed a job doing PHP programming (back around 2000ish) and wrote a bunch of sites for them. Then I decided I hated PHP and went to Python, and that was where my fascination for static HTML generators developed. Now my website, blog, and photo gallery are all static HTML (apart from the ajax twitter-based comments), which I find pretty awesome, but not really that web appy any more :)

Anyway my point is, start simple but not too simple. A challenge is good. A blog system is a pretty good start, since it introduces the mainstays of web programming (databases, forms, comments, etc.). Instant gratification is good. Then let your students find something they want to build.
I would love to see that study that contrasts the effect of money attitudes.

In my personal experience, at least, there's a huge difference between people's attitudes - even at equivalent means. By most people's standards, I'm rich. I don't think I'm rich, but I'm not attached to the money I have, or afraid of losing it, because I know that I can lose everything tomorrow and work my way back to my position in a year. (Because I've done it!)

On the other hand, I have friends who have as much money as me, or more, but who agonize over every little thing.

I would love to see if there's a scientifically provable difference between us, or if it's just my perception.

That would lead to the question of, can healthier attitudes about money be taught? Which is something of personal interest.

Why does no-one find it strange that Apple's antenna testing lab was "secret"? According to another article they were called "black labs" and no-one knew what was going on within them.

Now maybe this is just typical Apple PR nonsense to make something as humdrum as product testing sound sexy but if not then it's mind boggling.

New employee: "So where do we test the iPhones radios then?", "We don't", "Oh, okay, so what does the antenna engineer I met at breakfast do in that building over there all day", "Nothing".

Having your system running on intel chips, I can see why that would be kept secret. Keeping your new models secret before launch, fine. Secret anntenna testing for what must be the most famous phone in the world, I don't get. Where is the benefit?
