I did a 6 week MOOC on statistics from Coursera. I am a Math and Chemistry teacher and I did the course to upgrade my own knowledge. I wasn't working at the time and I was able to put in about 10 hrs a week.

I was impressed. It was better than any other face-to-face uni courses I had done.

I liked the interaction with other students. There was a forum and a Facebook page where we helped each other. I liked getting study notes from other students and I liked guiding others in solving the problems.

A video was better than sitting in a lecture hall, suffering from information overload and unable to stop the lecturer. A video I could pause and take notes. I could rewind to hear something explained again.

It took about an hour to get through a 20 min video. Originally the videos had no text, but, following an outcry from the students, text was supplied. For me, notes would have been better: I could have listened to the video, using it to expand the notes.

What was wrong with the MOOC? A thousand and one things if you simply counted the number of pages in the Forum.
- Video presentations are too dry.
- The assessment doesn't match the videos.
- Videos have to be supplemented with text.
- The course description doesn't clearly explain what prior knowledge you need.
The saying "You cannot please all the people all the time" springs to mind.

What are deal breakers for MOOC? Paul Graham believes that online learning will more easily cater for uni courses than school-based assessment. The block he says is the bureaucracy oversight that surrounds schools.

Why does this bureaucracy exist? To protect and nurture the family's greatest asset, the children. In advanced economies, with children no longer working beside their parents in the fields, schools are a means of ensuring one's children are safe and learning skills that will generate an income in the future.

As one teacher with grown-up children explained it to me: "Schools will always be necessary - with both parents working who is going to babysit/teach their little darlings?!"
Many of us have electronic devices from the 1980's and early 90's that haven't failed.

Until Congress sold the television spectrum and the FCC ordered broadcasting to cease, many of us still had non-HD TVs.

When you have a NASA failure lab implicating tin whiskers in the Toyota accelerator deaths we can call it more than 'annoying'.
Even if it's not software, you should learn about the relevant tech (assuming there is some). You'll have an easier time hiring talent later, you'll need less upfront costs, and investors like co-founders who have a good understanding of the technical aspects of the business.

If it's tech, but rather material cost, then crowdfunding is a good bet AFTER you have locked down a good marketing plan and secured some early traction in the form signups / commitments.

You can do tests and "fake door" type experiments to get user signups, or even commitments from potential customers to further validate your understanding of the model and relevant addressable market.

Once you've gone through that testing and validation process, try building out a small MVP yourself, or use what traction you mustered to try and recruit an equity partner with the relevant experience / network / talent necessary (and/or go get some angel money).

good luck
This technique, as it is shown, is not going to be possible for at least the next 5 years. They either know it and are making a huge fake marketing campaign (for a possible Google acquisition) or haven't realized it yet will have a really hard moment when they realize it.

Couple of components which are not going to work:

1. A see-through glass with Field of View as shown in the video just doesn't exist today. The model they are going to use are more like a ‘tiny TV-screen floating in your view’ and not even close to the visualization they created.

2. Real time 3D gesture recognition from point cloud data on ARM (+ overhead for applications + games all in low latency)

3. Real time 3D environment reconstruction from moving point cloud data (requires something like quad-core i7 + 32 GB RAM + desktop-class GPU processing)

They want to achieve it on an ARM running from tiny batteries!!!

+ On top of this would come the whole application / game experience, something they seem to be concentrating on, instead of getting the basics right.

4. Then there is latency, which is just not going to be solved for the next 5 but more probably 10 years, just read Michael Abrash blog about the reality of Augmented Reality glasses (http://blogs.valvesoftware.com/abrash/).

To be clear, I'm not saying that they won't be able to make what they promise, I'm saying that not even Google or anyone will nearly be able to achieve it for at least 5 years, and everyone knows this who is even a little bit into augmented reality.

So personally I find the Kickstarter campaign to be a fake campaign and it is just bending the rules of Kickstarter which requires a real-world hardware prototype. So they made a glued together prototype with a fake visualization, with the whole campaign built around the video.

Nonetheless, the campaign has a chance of being a massive hit, because every sci-fi fan is dreaming about it for decades and is willing to back it if he has the funds. In that case, it might have a chance of the biggest Kickstarter failures of all time. The best case for them would be a quick Google acquisition and integration into the Glass team.
It's not software, no. If it was then it wouldn't require some significant bills. It sits on Netflix's model. The industry that this caters to specifically has no player doing anything even close. I mean, how long did it take before we had DVDs by mail?
Jack Dorsey: The Future Has Already Arrived
"If I could explore the world, if I could craft something and really learn how to build and how to build a vision of what I wanted to see in the world – I could do amazing things…always.

The most important thing for me to do is to see a picture of where I want to go – see a picture of what I want to do in the world – and then figure out how to work backwards from that.

William Gibson said, ‘The future has already arrived. It’s just not evenly distributed yet.’ This is exactly how we run our companies as well…An idea that can change the course of the company can happen anywhere in the company. The future is already in all of your heads and your work, everything you have to do in your life is to distribute it.

Realizing that picture and making sure that I am distributing my idea, distributing my picture…is the most important thing – it’s to have that strong vision – to have that strong sense of what you want to do in the world – to be selfish to build something for yourself and be able to convince others to do the same. -Jack Dorsey"
Most motherboards and PSUs from this period had these faulty capacitors. I had a computer going bad because of this twice, once in the motherboard (Asus), then the PSU (Thermaltake). Luckily I learned about this and replaced the caps my self, but fixing electronics isn't the norm.

Think about all the electronic junk piled up because of this espionage slip. All the hidden costs and environmental impact caused. I'm sure even software faults could be attributed to that (at least the famous BSODs giving Windows a bad rep, I'm sure). Something impossible to calculate.
Sounds interesting. But you may want to look at online resources and other apps to see if they do not currently offer the information you are looking to provide. I am not sure how much traction your book/app would have though. There are so many travel books and apps now that your offering may get lost in the noise of the other offerings.

Perhaps, you could try partnering with existing sites/apps/books to offer this sort of information that they could incorporate into their offering. You would need to show how the experience would be for the users as well as how your information would add value.
There is some relevant tech that I'll have to look through. A lot of logistics has to happen for everything to go smoothly. And, like always, it's better to do it right the first time rather than playing catchup when money's knocking at the door.

I like this fake door idea. Good words, thanks.

Personally I've seen more vitriol and misplaced anger from pro-Google commenters.
I haven't benchmarked the mysql drivers, so results might be different there.

There's some work being done by openresty author w.r.t. ffi for openresty itself, it might yield interesting results. And yes, I think both the option you listed are viable. But the lua drivers already perform very well.
The most annoying part for me was

"This being a normal scenario in any event loop-based model like Node.js, the logs are crossed between multiple URL transactions, and the reporting tool shows scrambled output. We have worked out both short-term and long-term resolutions for this issue."

which sounds like a serious problem for pretty much anybody.

I know they're not obliged to tell us their solutions, but come on, they're a big company with lots of smart engineers and billions of dollars. We already know they can solve problems, telling us they've done so is neither interesting nor useful.
That's not necessarily true - people like to hire people like themselves, there are a good number of people in the small company world that think similar things about working for a big company but don't say it. If he's otherwise qualified, it's pretty likely that one of them would want to hire him.
Are you guys using refinery? (layout-wise it looks like it)

Assuming you are talking about web applications from banks and non-tech Fortune 500 in general, it's because many of them are:

* incredibly bloated (and still lack most of the features
that an actual human user would want)
* poorly coded by armies of outsourced programmers
* using over-engineered code built on top of obsolete frameworks
* running on a "homologated" stack, which is often 3 to 7 years out-of-date

(I know because I was partially responsible for some of them, in my dark past.)

I'll say for the record that I have no problem removing the term "low brow" from my comment. Just... pretend it's not there or something.
Where are the photos stored?
I should have mentioned that this plays on the Netflix model. And, with that, well, how long did it take before we had DVDs by mail? A longggggggg time. So yeah, there's the typical retail outlet for this stuff, you're right. And this market specifically is ginormous and will always be there. But there's currently no member of this market that's decided to go along with the Netflix model. And, at least to me, I see that as a huge opportunity.

>third implies that the victim is able to overcome the problem and let it slide off of their back.

I don't think she's saying that. These events are serious, but they're just one event among a lifetime of events. If you needed to use a wheelchair to move around, you would want people to respect your mobility limits, but you would emphatically want to be more than just your wheelchair. This does not imply an expectation to let that you should let the injury "slide off your back," but it does mean that it's your life and we should all let you decide how to deal with it. Don't push your understanding of how I should feel on me.

The author is saying, yes, these things happen and they're bad. But let's not lose sight of what we are here for. We are all more than our injuries, and even (especially!) when those injuries continue to haunt us we should strive to do more than focus on them.
I'm really unconvinced that this continues to be a current problem, and the Wikipedia article is definitely not clear on this. If there are recent examples of this that are clearly documented, it would be great to see some good hard data or sourcing, either here or perhaps the Wikipedia article's talk page.
>Suppose that 90% of our children can be made better through proper upbringing and 10% can't

The problem you have instantly with this type of analysis is to know if you really can't for sure. I didn't speak till I was 5. I have rare genetic disorder (1 in 50,000 odds). At preschool I was labeled 'retarded' and 'not fit for primary school' by a teacher. My mom never gave up. I had the highest GED score in high school. I was vice-president of a Student's Union at the University. I work just a regular job, but I live comfortable life of a professional.

How would you know who is a hopeless case and who is not? There is no way to know unless you try. Just like with starting a business, lol, you won't know if you're going to succeed unless you try.

That's why we have moms Man. Because they always try and believe no matter what. And I think I'm a good example why Nature made them this way.

Heroes and Flaws
Your question is really vague as you didn't give enough details about what you're building or what you'll like o achieve. Still, i'll try to answer.

You need:

0. Can you do it manually? Without any code can you provide this service? If yes, start here.*

1. Feedback - this is not easy without a product but draw something, sketch something or create a model in autocad. Show people and talk to them about how you plan on making their lives easier with it... Are they excited?

2. Product - if its a physical product, go and find money an then post again.

If its software, build a website, create a mockup of your app and start selling pre orders.

3. Reduce your product - Kill everything else except the core feature that makes you awesome. That's your MVP. I'm serious, just ONE feature.

4. Hire a developer - or start looking for a tech-cofounder. you should learn to code, but you should also build your business while you do it. Your pre-orders will make developers more welcome to your approach.
I think it's a great idea and we've been evaluating it.

However to make it happen our system needs to have 0 false positives and we are not here yet. If your system made a mistake and you just disabled the account, angry customer will appear on the chat support in 5 minutes and the problem is solved. On the other hand if you pretend to be sending, you can loose all the customer's emails and that'd be nightmare.
Then my apologies. =]
And do your best to test the damn thing. Stealing it can be almost as hard as inventing it (if turns out to be harder, fire your industrial spies).
I personally had two motherboards with this problems and one monitor. I also had 3 graphic cards. Only two of the graphic cards were still under warranty so I had to eat the cost of most of these premature failures. We also had numerous Dell computers at work fail but they were all out of warranty by the time they failed. Knock on wood but my last item failed in 2011 (graphic card) so hopefully this is over.
Even well made electrolytic caps are often the shortest lifespan components in a design, so yes, they are still a problem. But this was also a poorly chosen electrolyte.

Free Education Meets Resistance as Professors See Threat
Hi Julien,

Thanks for the note. I'd like to get to the bottom of this and make the Go test representative of best practices. A previous decision may have been made to favor an implementation that was measured to be faster at the expense of best practices [1], but that is not irreversible.

I am not a Go expert and I believe you are, and certainly @bradfitz is as well. If you two tell us definitively to change the Go implementation to better comply with best practices, I'll see that it's done for Round 6. I apologize if you feel we stepped on your opinions in any fashion. I really value your input in the project to date and hope it will continue.

You're aiming at whatever is in front of your barrel. Never point a firearm at anything you're not willing to destroy.

Besides, in this specific case, the whole point of DU is massive penetration, so of course it's going to eventually end up in the ground.
> Why is Ubuntu still going forward with Mir? Why not just use Wayland if the 'shortcomings' of Wayland that drove them to create Mir don't exist?

Maybe the switching cost of moving to Wayland outweighs the remaining cost of completing Mir.

Whatever the reason, I'm not complaining about the result, since I actually think it's healthy for multiple competitors to exist in the same space, especially for something as widely used as a windowing system:

(1) They can cross-pollinate ideas

(2) Competition puts pressure on sub-par projects to innovate.

Regarding (2), IMHO it's much easier for your project to innovate when a competitor who's on your radar pulls ahead in mindshare or market share gives you the kick in the pants you need when you're merely starting down the road to stagnation. If you're a near-monopoly on your market niche (post-X FOSS windowing systems in this case), you can get completely ossified and not realize it until everyone leaves as soon as your monopoly disappears due to new competitors (funded by the fraction of your own dissatisfied customers who have deep pockets) -- a position which is much more difficult to recover from.
To be fair, they do have a real-video below the pitch video (http://www.youtube.com/watch?feature=player_embedded&v=o...) which is much more honest and realistic look at what's being developed.

This is actually pretty exciting tech, but it's going to be absolutely nothing like what they have to show in the pitch video.
There is some nascent technology that allows the eye to converge on two focal planes simultaneously, which looks like it can solve the bluriness problem[1], but I don't get the impression that meta is using this. And it doesn't solve the issue of ensuring parallax alignment between the display screen and the background, which can only really be done if you're tracking the pupil and compensating accordingly...

Two words I think pretty much summarize my general sentiment towards Zynga.

"Dinner With Friends" is a play that won the Pulitzer Prize in 2000, but I'm sure there are earlier examples.

http://www.amazon.com/Dinner-Friends-Donald-Margulies/dp/155...
Their claim is that it'll cause confusion, but my thoughts are: if you're going to trademark a common English phrase, you should be prepared to deal with some amount of confusion. People have been doing stuff with friends before Zynga came along.
If they were serious, they would have sent more than an email.
Sounds exciting. I would advise you to look into why the retail outlets are not using the model then. See if you can glean some points as to what they saw that keeps them out of it and see if you can come up with an idea around it. For example, if you look at the Netflix model it requires them to have several warehouses with several dvd's in stock constantly in order to meet demand. How could you alleviate this cost? Perhaps by offering it in a limited area initially.
Yes, but to set expectations before we even implement the server statistics capture we have planned: we want the CPU to be fully utilized for most of these tests. If you barely see the server showing up in top, something is probably going wrong (or you've run into a different limit such as disk or network).

We're testing the maximum number of requests a server can handle per second, so the optimum is for the CPU to be fully utilized. A different test would measure how much CPU is used if I want to serve X requests per second.
Personal branding for (software) engineers. SEO proof you (the product).
This is how you treat credit card fraudsters too. Those that use your site to run a bunch of stolen cards trying to find the active/good ones. You start telling them they're successful or false randomly in what looks like a normal process.
Well, mathematically you're constructing a synthetic put.

You're giving up the potential upside in the stock while keeping all the downside risk. The "premium" or lotto ticket you're selling is your compensation for foregoing any upside past the option's strike.

People seem to forget that, in general, options are fairly priced.
DivvyShot, acquired by Facebook, had a very similar product.

I'm starting to think this is a pretty good strategy - recreate apps that have been recently acquired and sell them to a competitor of the original acquirer.

Here's the library in question - https://pypi.python.org/pypi/pbs - it makes me super happy to do shell work in python.
Am I the only one that thinks this is a legitimate? I could see myself thinking anything suffixed with "with friends" that is an app as part of the Zynga range.

Granted that fact that it isn't a game could be enough to remove some of the confusion.

The best way to get good projects in a company is to get put on a project that's failing and make it succeed. My first boss at Google did this - he was on a project that was going nowhere, introduced a bunch of modern software-development methods to the team, and got the project unstuck. He's a Principal Engineer now.

This is probably harder than taking a project that doesn't exist and making it exist, but that's why it's also more respected. It shows that no matter where you land, you'll be able to make the best out of it, and that makes you incredibly valuable to...everyone.
