1. In the HTML email put

<img src="http://myserver/invisible.gif">

2. Serve up http://myserver/invisible.gif with a process that trickles down an endless GIF image a few bytes at a time.

3. When the connection to the endless GIF dies, call that the "reading" time.

4. If a "reading" time is under some threshold call it "deleted".

That's how I did it a few years ago anyway.

I guess that could work if mail clients don't have timeouts for images.

I still can't imagine how they would detect deletion though.
Are images blocked on hotmail, yahoo, etc. too now? I've only used gmail for the past 5+ years.

Either way though, it wouldn't really produce a random sample, though maybe it would allow somewhat meaningful comparisons between separate email campaigns even if the absolute numbers aren't too meaningful.
This is why I block graphics, run mail in a separate browser instance etc. GTFO of my business.

It took them until 2011 to come to this conclusion? It's been needlessly redundant for far to long.
A better title would have been "On NIH Syndrome for software used in financial markets" or something like that. I thought I would be reading a generic opinion about NIH syndrome. Instead, the post was more valuable than I would have suspected from the title alone because you address NIH syndrome from a different perspective. Thanks for sharing.

A couple of questions/comments:

1) Something we've heard a lot from PG: Is this your biggest problem?

2) What prevents random Hacker McHack from reproducing your company in a couple of weeks and releasing it as open source?

3) You don't want to mention your monetization plans, but are you sure the income from something like this can support a company? I can see why people goes for companies like Tumblr/Posterous (huge, huge, huge audience), but your service by comparison looks like something too "nichey" (not bad, but again, not the scale YC is looking for).

I'm sorry if I sound blunt, but as it stands right now, compare this to Heroku, Justin.tv or Greplin and tell me again if this is something you think fits their idea of a good startup.

Without reading your application it's hard to see what plans you have for this, maybe I'm just blinded by what's only in this post. Your ebooks idea sounds like it could be _super_ interesting.

I hope this feedback helps you :)

It's common for politicians to sit on the fence, otherwise they risk alienating some of their voters.

They say things like (not a quote) 'we need to balance both sides' etc even when the idea is truly stupid.

Only a few politicians have some balls to make a decision upfront.

> I used prostitution as an example, I personally don't see why it should be illegal. However heroin addiction is not the same as corporations and governments lobbying in cahoots. Drugs aren't really viable for an effective lifestyle - at least, not the ones organized crime profits the most on. Even prescription drugs like Vicodin were nearly pulled off the market because of how dangerous they are, even when used correctly and in moderation.

Who are you to dictate what constitutes an "effective lifestyle" for anyone but yourself?
Or they are legally required to by their clients and or government regulation.
Legalizing something harmful because there are other harmful things that are ALSO legal isn't sensible. It just means more things should be illegal.

And they are adverse because they are unhealthy for consumption. That a prison is unhealthy says more about the American prison system than the comparative health of narcotics.

There are a lot of responses I can't cover individually, so here is a thought experiment to extrapolate the restriction and legality issue further: why regulate anything? Why restrict anything? We can viably allow murder and rape to exist as well if gun laws have no regulation - every one is responsible for themselves, and forget the rest.
Big boys move slowly. Plus, what isn't "easy to replicate?" aside from network effects.
I disagree. I believe there are plenty of avenues of criminal activity. Trouble is, most criminals aren't visionaries, and why would they have an incentive to fond other profitable crimes of they can practically earn money doing what they do now?
What makes someone "horrible"?
well i wasn't talking about this case particularly.. i was talking in general alexa isn't considered nearly a credible source of getting info about sites. The obvious reason is that most people don't use toolbar. (browsers like chrome don't even have toolbars, browser toolbars are ancient)
I agree that rehabilitation is more important that penalization for drug abuse, but towards the original point, drugs aren't accessible in the sense that they're not legal. You cannot get them as easily as you can a gallon of milk.

Anyone up to meet and talk ideas in SF?
I'm new to SF - been here for about a month now. I have a couple ideas I would like to bounce off a hacker or two (my background is in strategy/finance) looking for something to potentially work on. At the very least, it would be nice to meet some people and talk about the industry.

Shoot me an email at tranmchau [at] gmail [dot] com if you are interested.

If that's true, it's very dangerous. Imagine somebody finds an iphone image vulnerability, a virus based on it will spread across the whole world in a couple of hours.
A concept video, in contrast, is just a bunch of special effects. It exists free of any constraints.

I disagree. If anything a concept video shows you where your constraints are. Concept videos aren't so effective for showing you what you can do -- but they are effective for pointing out what you're NOT thinking about (where you have effectively constrained yourself w/o knowing it).

For example, would a 2005 concept video show people using a stylus on a tablet like device? I suspect quite possibly. An astute concept video watcher would question that. And hopefully open a conversation about it in a way you can't do with a tech demo (because people can shoot back in a tech demo that you need a stylus for a resistive display and capacitive is too expensive).
It's not the technology that matters it's what the company offers to you to help you grow (classes, training, good team, etc).
well that's when you (from previous round) are going.. i got an email yesterday from them confirming my submission and saying that the results will be out December 15. So Jan 16 would be a little early imo, for all the visa and paperwork will probably take longer. feb/March sounds more reasonable. :)
I'm really not sure how well this kind of thing can scale. Without some formal accreditation process for instructors I can't see this bringing in corporate workshops and seminars which are where I'd guess the money is. Having to evaluate every instructor and every curriculum is going to only get harder as these sites grow.

Sadly, I think this kind of thing is going to stay firmly in the realm of the hobbyists.
Interestingly it appears that the ML-class (http://www.ml-class.org) and DB-class (http://www.db-class.org/) are not associated with Know Labs. But I might be wrong. I initially thought all three of them was a part of a Stanford effort to push their own name even further (perhaps in response to the online MIT lecture videos that have been quite popular in recent years).
I used to be in the auto industry, and by far the most mind-blowing part to me is that the team produced a prototype in 12 months. That's difficult to imagine with one company being involved, let alone 50!

Hats off to German Engineering and this rather unique instance of collaboration!

They already do this.
The way it was hyped when initially announced made it sound very much like it was Stanford running this, and that was my presumption.

I happened to be curious after a conversation with a friend about the course, and when I went to have a look at one of the homework assignments, realized that they aren't available to those who haven't signed up for the class. That's just fine, and I respect that Know Labs and the instructors can do whatever they want (and it's fantastic that they are making a lot of the materials available). However, it struck me that this was marketed as being about open education when the reality is that it has the potential of being much more locked down than MIT OCW or the Stanford courses that do have lectures, complete syllabi and assignments freely available on the web.
They also have an ad over the list of emails in the inbox. As of yet I have not seen this ad in the actual product.
Indeed. There are no leaderless, emergent movements. All modern seemingly complete democracies merely have a shadow government.

I worked at an ESP (Email Service Provider) a few years back. It may not be anymore, but it was a crazy environment back then of everyone trying to compete.

The major issue with this is going to be scaling it, with large ESP's doing 50-100 million messages a day, and 20-30% of those being opened, that's a lot of processes. This solution will probably be effective, mostly because it's going to a much smaller segment.

Surely Anonymous, or a more skilled hacker group could do this. To hit the cartel where it hurts they must hit their money supply. Instead of publishing members, track the money and reveal where it's coming from and where it's going to. With an annual income of $1B there has got to be something sizable to be tracked.
If I thought you knew it, I wouldn't say it. I don't see why that's offensive - I can see why you wouldn't like it, but your comments make it sound like you've never handled this kind of criticism before. Prefacing my statement with "surely" or "as I'm sure you know" would frankly be disingenuous, because I certainly did think you had not dealt with academic-style peer review.

This style of criticism - no frills, no pleasantries, not even necessarily any suggestions for improvements, just "this is what you did wrong" - is common when reviewing research. I, in fact, have five such reviews of my own work I need to rebut.

0-day Vulnerability in Windows Kernel exploited by Duqu malware
i never load images automatically in my emails, and I bet a lot of other people do that too
I do not want exactly to complain since the class is currently free and I am enjoying it quite a bit, but there is a lot of issues. The integration between the Youtube video and the quizz is poor, no official forum for the student, no lecture notes. Everything as a very beta feels to it.

On the contrary the platform for the ML class is of very high quality and the content more polished. I especially like the possibility to speed up the video lecture, having programming assignment, and how easy it is to submit them.
Divorce Mediators in Central Florida
Very interested in the "internet of making things" (or project-driven, as @ataugeron iterates it here. Have been working closely on incentives around learning by doing and so far feel that these will help: 1) Recurring and consistent "prompts" (daily challenges, sure, but try to start out with some frequency you can keep up).. compare The New Yorker cartoon/caption contest; 2) Community involvement -- let other users comment and upvote, not just "best" pieces, but "most improved", "most imaginative", "most surprising" etc; 3) Let users lead: perhaps pick one of the "winners" of the above and let them post a prompt of their own and maybe even judge the standouts.
Seems pretty straightforward.
The 'wavefront-expansion' algorithm does a breadth-first expansion from the goal node, to every other node. As this is done, the distance from each node examined, to the goal, is stored.
Afterwards, in order to move towards the goal, an entity at a particular node, moves to its neighboring node that has the shortest distance to the goal.
The difference is that this is a class that you participate in real-time. Each week you cover the same material as everyone else in the class. The alternatives that you mentioned are all self-paced. Each has it's merits, but being able to form study groups for the class is helpful, and not likely to happen with some of the MIT OCW materials.
I'm partaking in both the AI and ML classes and I find the ML experience much more user-friendly and polished than the AI class. For example, being able to speed up the lecture videos is brilliant. I find the AI class video questions a bit frustrating to use. IMHO, Know Labs has a ways to go.

I don't think the aim is to charge students for courses like ai-class, but rather quite the opposite.

It would look to me like the idea is to create a platform to allow universities to create their own version of ai-class.
MIT gains a lot of positive press from OCW but it must cost them at least a little staff time and money to maintain and run it. I would guess there is definitely a market for a company to claim "Hey we're the guys behind Standford's famous AI class experiment, and for a price that saves you a lot of work and staff time you can have that same, well known, platform today"

Having worked in Universities for years, I know that at the institutional level 'buy-it' almost always trumps 'built-it'.
It's not entirely true in Indian tech industry. Every year most companies lose up to 20 percent of their workforce because they move to higher paying jobs and better companies. This is a serious issue that managers are usually at the mercy of their talented engineers.

Some of the best things in life are commercial and still have a phenomenal impact on humanity...

I understand why people might be wary, like if the Khan academy suddenly opened up premium memberships, but this course was never designated as a non-commercial concept (though it was very much billed as a 'beta')

A bit of amateur Google-sleuthing doesn't really amount to a groundbreaking piece of news, in my opinion.

This makes a lot of sense. I was working through a couple of the assignments last night when I realized that a lot of the questions seemed to test reading comprehension rather than proper understanding of the material. I had a while back used Prof. Ng's video lectures and notes (available on his site) as a supplement to my own machine learning class and those are designed to both stretch your mind and test your understanding. I was kind of hoping that that level of quality was being shared with the rest of the world but that doesn't seem to be the case :(

I would interpret that to indicate that the function has several potential return codes, not just 0 or -1.

Who care?

How long are people going to keep believing that information you share with people who share with other random people is ... "private"?

I've friended spam-bots entirely for shits giggles. Seriously.

I like Facebook a lot. Seriously. I'm there pseudo-nonymously but constantly. But naturally I post nothing I don't want totally public 'cause nothing on Facebook is private to start with.

Define "privacy" in the context of Facebook. You can't and that's the point.
You seem to imply that IRCTC had no role in the train ticket booking done by Cleartrip and others; that it was completely initiated and done by the private companies.

It isn't that "companies have come in and done something about this"; it was IRCTC who first published an API that enabled these companies to book tickets. Without the API, Cleartrip and others wouldn't have been able to book tickets.

The other point about a better user interface, well they just don't have a better UI. At least Cleartrip requires more info in the first step than IRCTC. The PNR status functionality in Cleartrip doesn't work most of the time. Filing TDR (a claim for refund) for tickets booked is much more complex in Cleartrip than in IRCTC.

The only problem with IRCTC right now is that it can't cope with the rush at 8 am tatkal and opening day bookings.

The funny thing is that another booking site was made (by the in-house CRIS) and that didn't work for more than a month.
I use labels aggressively, but I monitor the numbers next to the labels to see if I have stuff coming in rapidly. When I tried the new GMail interface, it hid a bunch of important labels, requiring me to hover over that section to check if I was getting emails from particular projects and groups of people. That broke my email workflow, so I had to switch back to the old interface.

Hopefully, the comments I sent to the GMail team didn't fall on deaf ears - I really don't want to rework how I do email.

It must be tough working on a product that is so core to people's life and work. The changes in XCode never sit well with me either.
