Startup to launch after Secret London Facebook group amasses 180,000
but the big discontinuity could be caused by the frikkin super bowl. You know, the one where everybody buys chips and soda and beer.

(This is actually a bit unfair of me; my brother makes models to analyze the effectiveness of ads for Nielsen, so I know a bit about how difficult it is to figure out)
There is no inherent reason for science to be limited to this universe. Religion claims to be the answer to "why", science acknowledges that it is an open question.
That's true. I think, the affiliate is a good start. Once you're big, it's silly to leave money on the table. Obviously, you have to be careful with the industry you pick, so it's big enough.

What I'm speaking, though, is about relatively small companies. I don't mean VC backed companies with well researched markets. There's a lot of kids dreaming about big buck doing #31337 clone of Flickr. It's basically a waste of time, in most cases.

You have to be careful with the real products. They have their drawbacks, too. You have to do the support, reply e-mails from the actual customers, sometimes forecast the demand etc.

Another thing I literally love in the affiliate industry is their experiments driven approach. The best test (it even rhymes!). That's what Google do obsessively, too. (see Marissa Mayer vs Doug Brown thread)

I think there's a lot to learn from the affiliate industry. It's silly to get into usual moralistic standpoint: usually they have less skills than a regular wizz kid, and, somehow, manage to make better money.

EDIT: It's also good to have a broader perspective. When you're speaking with a client directly and agreeing on the fee, you're doing affiliate, too.
There are plugins for SVG that IE users can install, that would make this work, and be useful. That said, it IS a plugin that a lot of people aren't likely to have already installed.
This looks great. As a diabetic i've been considering doing something like this, now i won't need to :)

Some feedback:

Can't create new entries, get "We're sorry, but something went wrong."

Would like to be able to enter different types of mediciation, i use humalog+lantus.

A mobile app would be awesome. I might be able to help, i have iphone experience and a little android experience..

EDIT:
Prefilled time when creating an entry is off by one hour.. timezone/dst issue?
People think they understand them, but piecharts are hard to understand because you can't differentiate between a 24% and a 25% slice. Read a far better explanation here: http://www.perceptualedge.com/articles/visual_business_intel...

They are perfect for a very, very limited set of datasets: if you have a very large slice and a number of small slices and want to show the obvious difference.
It's so far from a perfectly controlled experiment as to be useless. You have sales before the ad ran (when it wasn't the super bowl), and you have sales after (when it was the super bowl). That's a huge confounding factor; everybody buys chips, soda and beer on Super Bowl Sunday.

They're not able to tell right away. They pay people like Nielsen millions of dollars to analyze the effectiveness of their ads at super bowl time. Those folks do regression analysis of the sales figures compared to previous years, with the knowledge of how sales in general have been, sprinkle with some bullshit so that the client will hear what they want to hear, and then deliver them back to the companies that ran the ads. (My brother does this job).

My point: they don't really know, and it's not at all easy to know.

edit @jonknee since HN won't let me reply: Except that you're advertising Doritos more than those other brands. How much of that purchase effect spike is due to your other advertisements, how much is due to super bowl ads, and how much is due to people simply feeling like Doritos are an appropriate super bowl snack?

Whoops. I'll correct it tonight thanks.
Take a look at http://code.google.com/p/svgweb/ - it renders SVG inside a Flash widget, providing compatibility with IE without the need for a separate plugin.
As one who occasionally ends up on the receiving end of these sort of subpoenas, I'm not surprised that a slightly broader dragnet would lead to much better information.

It'd be very interesting to know if there is some combination of cache/cookie clearing, adblock, noscript etc. that effectively breaks the chain.
I was about to do this. It's a great idea, it's an excellent market and most of the competition is terrible. I actually did my research on this so I know for a fact you'll be successful.

Just be sure to allow people recommend it to their family and friends. That should be a big part of your marketing - getting geeks to get their parents to use this.
I'm wondering what made them go with this oversimplified ad rather than one of their other glorified ones such as this one:

With the huge investment Apple is making in touch these days, this guy's investors were right to worry about Apple. No matter what happens to the iPad, you can bet the laptop line and OS X are going to continue to support more and more tablet-style features. He better make his money while he can.
I got my ex(unrelated I assure you) a sapphire because it had meaning in relation to our birthdays and we both agreed not to buy diamonds.

She loved it and our families thought it was great but we both had to deal with a lot of comments off strangers and friends about why I didn't buy a diamond. She was great about it but you could see a bit of disappointment in her whenever it was raised as she was just excited to have it and felt hurt that she had to explain why it wasn't a diamond. When they would ask me I'd list the reasons on the page and tell of why I picked the stone I did so it would only bother me when I saw her bothered.

The point of this story? Even when its perfect for you and you couldn't be happier there are large portions of society and people you honestly never expect that will go about criticizing you for not following the norm and you need to be prepared to have that conversation a LOT like every time someone sees your ring a lot.

That said I still wouldn't change it for the world though and I know neither would she and when your day comes I'm sure you won't either.

It probably wouldn't have worked for the last repair job, where they worked on things that had never been planned for repair (tiny screws and all that).

As an incremental cost, assuming you have a manned space program, you can't justify doing robotic repair due to the extra costs and limitations.

On the other hand the next big telescope project (http://en.wikipedia.org/wiki/James_Webb_Space_Telescope) will be non-repairable, but that sort of goes with its mission, which is to sit at the Earth-Sun L2 point. Design life of 5 years, they hope it'll make it to 10. Note that the Hubble has made it to 20 years and they expect it'll last at least another 4.

And I'll certainly agree with you that if you want to explore beyond Mars for now, do it with robots. And to put humans on the Moon or Mars, send robots first (as we did for the Moon and are doing for Mars).

On the other hand, if I wanted to thoroughly play with an asteroid, I would want to do it with a manned mission (after suitable earlier check-out by robots).

Seems like running memtest every six months or so would be a good policy.

It would be nice if there were a way to test the memory while a machine is running.
Google Chrome and Google Search are totally different products, pg was talking about search, so this comment is a bit irrelevant. Chrome is advertising everywhere (even the town where I was born which is in the sticks!).

On a totally unrelated note to this point, watching that video made me feel uncomfortable because that's not how I use search. I always highlight, right-click, choose search Google. Watching someone else do it differently made me feel a little odd...
MetaStartups. The first word that comes to mind. Really. Why bother applying to Y Combinator and go through all the mess of first months of the startup building process, if you just pick a bright idea, click a few buttons, and here you go -- soon you've got a working platform gathering hundreds of thousands of users? At the end you could just easily migrate with all your audience to your own domain, and tadaaaam... Sequoia Capital guys, where are you?

And what about Facebook itself? Why not provide a toolkit for startup builders? Like, you know, Google with all its cloud computing and tools for site owners, but only in this case for startupers. Inhouse startups. What could it be? So, you've got a platfor, with hosting, audience, tools for advertising. Actually, if only Facebook provided an opportunity to do server-side programming, so that a group (or whatever else it would be called) could deliver web services, not via this clumsy embedded applications, but directly, and also an opportunity to do your own advertising (of course, some share will go to Facebook), here you're done!

I absolutely loath french culture. Sorry. Every time I go there I end up with a bad taste in my mouth and a mind telling me "never again". It's like you cant win with a french person.

I have quite a bit of loyalty to Google. I use them for RSS, Email, Calendar, Documents, mobile alerts, maps and phone service among other things.

I have no doubt that Google will improve and adjust to any threats Bing might one day bring. The cost of me moving all of my data and changing habits to another place would be high. That and there is no way in hell I'd trust Microsoft with my data.

Tech4000: Synthetic Organisms with a kill switch
Great landing page, initially I was clicking around trying to figure out why such a slick looking tool was completely free! You really get across how and why your service would be useful.

A few little nitpicks, hopefully they're helpful: The bottom signup button isn't clickable. The orange 'join today' text could maybe do with a nicer font - more handwritten, less script. There's a small white square in the top right of your stock photo. Cutout outline visible on the woman's hair. The screenshots might be better popping up in a lightbox. The sign-up form struck me as generic, and didn't match the page I had just come from. The site root doesn't show my dashboard when I'm logged in. The icons next to the different types of entries look like youtube 'play' buttons, confused me for a moment.
This works in IE, it uses Raphael ( http://www.raphaeljs.com ) so IE gets VML :) IE is noticeably slower though.
Shouldn't the cosmic ray flux through each bit be the same for each bit, and unchanged as you increase the total amount of memory?

For identically manufactured ram, generally yes. The total number of upsets you'll see from a collection of 10 sticks of RAM will be roughly 10x higher than from 1 stick of RAM. However, there are huge variations in RAM, especially when you're comparing modern RAM to RAM manufactured in, say, 1988. The main figure used in the article (1.3e-12 upsets/bit/hour) comes from a study of a Cray Y-MP 8 system that had a main memory system containing approximately 32,000 SRAM chips. This amount of memory is measured in cubic meters, yet today the same number of bits of RAM fits on half or a quarter of a single DIMM.

Suffice it to say, the cosmic ray flux through the Cray Y-MP 8's main memory system and through half of a 2GB DIMM is significantly different, by orders of magnitude. At the same time, the memory cell in the Y-MP 8 and the memory cell in a 2GB DDR2 DIMM will have a different rate of sensitivity to cosmic ray flux, translating to a different rate of upsets for the same rate of neutron flux per memory cell. However, these two factors don't balance each other out, modern memory cells aren't thousands of times more sensitive to cosmic rays even though they take up thousands of times less space. The result is that a figure of upsets/bits/year can only be taken to be constant so long as the memory technology remains constant. That is most decidedly not the case here. If one were using 4GB of Cray Y-MP ram (which would likely fill an entire server rack, and more) perhaps you'd see the SEU rates the author calculates. However, most folks these days are using 4GB of RAM in 2 tiny DIMMs which may have, at most, a combined cross-sectional area (of the actual memory chips) of at most maybe 16 cm^2. This has non-trivial effects on the SEU rate.
When he says that he has learned to distrust beauty, what he should be saying is to distrust infatuation. It is infatuation that blinds us to the limitations of code (or anything else). You can get past the infatuation and beautiful code will still be beautiful -- even though you can see its limitations.
I am Buddhist my religion specifies no conclusions regarding the age of the universe, evolution etc. If you meant Christians well my wife is Catholic and while they are a little slow on the up take (aka Galileo). They currently support Darwin etc.

I am the father of a Type 1 who is 8 years old. The problem is the same with any of the diabetes tools: you have to manually enter the numbers. Until you can get around this fundamental problem, you will have difficulty getting people to use the app. A mobile app helps, but it really needs to be automated. Also, many people will not share sensitive health information with a random website.

Keep an eye on what Google Health and Microsoft's Health Vault are doing. Good luck.

I see the same problem. But this still makes it easier than typing it down in a notebook, especially if there's a mobile app.
We may charge money for it in the future. But thats not likely for at least a year. We want to focus on building a community around it. Plus we both have full-time jobs already.
It's built on Raphael ( http://www.raphaeljs.com ) so VML :)
Odd nit-pick: When prices of things rise faster than they should, we call that inflation.

I have no idea what "faster than they should" means in this case, and it frankly doesn't matter - it's inflation if prices rise at all (and deflation if they fall).
Moreso - I worked with a direct marketer / affiliate marketing agency for the first 8 months I held a full-time job; they were primarily in lead generation, of course, and got most of their leads from other lead generation companies, who got theirs from still others.. at the end of the road, those leads were coming from people paying bottom dollar for half-baked PHP apps. And by the time those leads actually reached the entity (online education, in our instance), they had changed hands three, five, and sometimes more times.

At each instance, of course, their personal information passed through companies who had no moral qualms about holding onto those leads and passing them off to a future client as new.

That's what's shady about it.
I am diabetic (type 1), and I have been meaning to make this for years. Damn you!
This issue is starting to cause some widespread panic on the Digital Point forums. I had some outsource work done for me there and I've tried two times to get my payment to go through and each time it's been reversed and I've been credited back the amount spent.

It's made it impossible to get anything done over there, at least for the time being, as more and more of DP's user base is located in India.

" Sometimes the right hand doesn't really want to know what the left hand is doing."

I agree. There's a level of plausible deniability with using affiliates. They can resort to some black-hat tactics and when they are caught, you can claim you didn't know, and ban them.

"Google takes huge, huge amounts of money from advertisers whose hands are less than clean."

I agree with this, while noting that almost all ad networks do. No one wants to admit it, but a lot of the internet was built on rebills and affiliate ads. Now Google is bigger and has some large clients to keep happy, so they push back harder on scams as they crop up. But as long as rebills exist, Google and others are stuck playing "whack-a-mole" with the latest flavor of rebill.

The latest FTC moves have put some pressure on affiliates, but it's just a matter of time before they come up with something else.

I don't think the issue here is whether or not it is a form of social signalling - it clearly is. Nor is the question whether social signalling is useful - again, it clearly is.

Rather, the point is, social signals are often (and certainly in this case) based on symbolic value, which means that they may be open to "semantic hacking" that transfers that value to a less damaging alternative.

That doesn't mean that the value of a diamond is unconnected with its physical properties. It is likely that diamonds are "special" because they are rare, hard, shiny, etc - all of which helped diamonds achieve their niche. But that is an historical explanation. The social signalling (that you want to indicate to someone their value to you) could be done equally well by some other "symbol" if a common social understanding can be constructed.

So it's interesting because (1) hacking social systems is inherently interesting and (2) the diamond industry is itself associated with various negative side effects that sit uncomfortably alongside the notion of "love"...

Many of us already have.

The lack of a Universal Theory of Software Design != "no general principles or techniques".

Anyone programming today is standing on the shoulders of giants. Their trial and error is our starting point. No, they didn't figure everything out, but it they had, programs would be written by other computers, not us. Maybe someday, but I, for one, am not quite ready for that.

Failing to call "delete" on a pointer you "new"'ed in C++ is also clearer, and just as incorrect. The ECMAScript spec makes no mention of how memory will be managed for the user. Right or wrong in terms of clarity, it's still a poor practice to assume the browser will behave in a particular way that's not covered by the specification (regardless of how sensible that behavior might be!).

The author touches on the "how much memory is in use" question: all major OSes use unallocated RAM as a file cache (or equivalent), so no matter where the error happens, it is almost certain to hit something. Whether that "something" is actually relevant is another matter.
