I'm not trying to dissuade you from using prgmr, but EC2's reserved instance pricing makes it a lot more competitive. You can get the 3.75GB medium instance for $55/mo (1-year commitment including the up-front fee as a monthly cost) which compares nicely against prgmr's $68/mo 4GB instance ($14.67/GB vs $17/GB).

In fact, I'm wondering how you came about your "I'm able to run infrastructure comprising ~500GB RAM for literally 3% of the cost of EC2" calculation at all. Even without reserved instances, Amazon has their 3.75GB instance available for $115/mo (or $30.67/GB). At $17/GB, prgmr is more than half the price (~55%). That is a savings, but certainly nowhere near 3% of the cost.

IIRC, prgmr charges $4 plus $1 per 64MB of RAM. Assuming that they'd sell you a 500GB instance, that would be $8,004/mo. Since you'd probably have to spread it over more machines, it would likely be a bit higher. Anyway, even without dipping into reserve pricing (using the quad XL high-mem instances), you can get 500GB of RAM for $9,000-$10,000. Again, prgmr is a bit of a savings, but in the 10-20% range.

And here's the big point. If you're using AWS for on-demand instances in that range, you're likely to want the hourly billing and rely on the fact that Amazon has much greater scale. Prgmr can have a queue for more capacity so clearly they're not accommodating someone like Netflix who needs 1,000+ boxes to do encoding for a week when a new platform comes out and then shuts them down until a new platform comes out. If you're running a more predictable infrastructure (which it has to be to an extent to go with a smaller player), then you can use Amazon's reserved instances. Amazon's reserved instances beat prgmr on price.

Now, I didn't calculate in storage or bandwidth into Amazon's costs, but even with those additional charges, I don't see how you came upon prgmr being 3% of the cost of EC2.

For my own personal server, I have an EC2 Micro instance with 1-year heavy utilization. That means that I pay $8.77/mo for 613MB RAM - a discount against prgmr's $12. Now, I have to add storage to that - the 12GB that prgmr offers would cost an additional $1.20 - and bandwidth, but I don't break $12 for my usage. If I wanted to commit to three years, the cost would be even less - $6.38/mo.

None of this is to take anything away from Luke - he's literally written "The Book of Xen". That said, Amazon's pricing isn't much more expensive. Their reserved instances can be a good bit cheaper. Amazon also has the scale to accommodate you more easily. Prgmr can't keep thousands of spare boxes on hand and they (as you noted) have had queues for instances. Amazon is by no means the be-all and end-all of Xen instances, but it's pricing isn't that bad (and in fact can be better) and there are advantages to using a company with Amazon's scale.
In addition to the Brewing the American Dream program, Jim Koch has done a lot to support small craft brewers. When there was a hop shortage in 2008, the Boston Beer Co. sold 20,000 lbs. of hops to brewers at cost [1]. It's addressed in the documentary "Beer Wars," which I highly recommend [2].

Some background on this post.

It is a discussion on the AGI (artificial general intelligence) or OpenCog mail list regarding the use of virtual credits. One of the late comers to the project (Yan King Yin) feels that given the effort that needs to be put in for AGI development, some sort of compensation beyond bragging rights, would motivate him better. He proposes the adoption of virtual credits, and the OpenCog project leader, Ben Goertzel gives his reasons why it might be a bad idea.

For anyone who has wondered what motivates people working on opensource software development, this discussion provides some interesting insights.

In addition to Latitude, the built-in "Find your Friends" seems to already do this, without the user needing to explicitly provide consent every time after the first.

You should clearly state why your app is better.

Also, I know this is hard to do on iOS, but it would really be nice if it could use Google Voice, or email/gmail, or some method other than texting. A lot of people still don't have unlimited SMS plans.
I haven't looked at the schematics yet, but generally a SoC based design like this needs at least a six layer board, which combined with the speeds it runs at is pretty advanced electronic design...

Coupled with that, it can be really hard to get low volumes of some of the parts they use, like the SoC, PMIC (power management IC) and so on (although you can get free samples if you ask sometimes - but they generally won't give them to you unless there's a chance you'll put through a big order with them in the future). And soldering the BGA parts onto the board would be a pain unless you pay for it to be assembled for you...

Unless you know a lot about that sort of thing, it would probably be more successful to design something that interfaces with a Pi.
I'm just curious (and not trying to be a dick), but how come you didn't come across the product sooner? It seems that it had huge appeal.
Since they are startup, I assume they have a pretty close relationship with a lot of the bars they are working with. I wouldn't be surprised if the founders visited the bar and set things up themselves. In this scenario, it's much more likely that word would get back to them about sex in the bathroom.

If evernote doubles it revenue every year for the next four years, it would still be trading at 3 times revenue, a number that might be realistic going concern assuming they have very high profit margins.

So valuing them at 50x revenue now is saying all returns will come from outperforming 100% annual growth... color me sceptical.

Q: How do you rank yourself among writers (living) and of the immediate past?

Are you aware of anyone experimenting with the automatic evolution of web pages?

For example, use genetic programming to periodically modify the page served up. Both pages are served up, A/B style, and the page which has the highest metric (eg. $ earned) survives. Repeat.

It would be interesting to see what the results are after an extended period of time.
Very very nice.

One observation, on the export it looked like it was trimming the result and not including the entire lines. I had two circle shapes, one over the other and at export it clipped the top of the top shape, and bottom from bottom. Almost like the math is calculating from the center of the line shape and forgot to account for the line thickness when calculating export cropping.

Thanks for making this tool.
But did Instagram have revenue?

While that's a valid question, one sale of one company does not a bubble make.

We really, really have to stop saying "bubble" every time some company gets sold for a greater amount of money than we think it's worth.

Ask HN: How to teach programming to kids (6-14 years)?
I have been thinking about various ways in which we can teach programming to kids in age group 6 to 14 years. There was one interesting article posted on HN few days back about the same. I am thinking about similar ideas like combining the programming with some physical prototypes (eg. a robot) to provide good motivation to learn and also make it fun. Would be great to get opinion here on different ideas and alternatives!
Grammar trivia: "children" contains redundancy, a doubled plural. The germanic plural of "child" is "childer", and that didn't sound plural enough, so they added the -en that pluralized such fine words as ox -> oxen, and child-er-en then sounded correct.
RubyGems 1.8.23 is also out with the same fix.

Two security issues were fixed:

* RubyGems did not validate SSL certificates (the dreaded OpenSSL::SSL::VERIFY_NONE problem).

* RubyGems allowed HTTPS-to-HTTP redirects. And in fact rubygems.org did redirect gem downloads from HTTPS to HTTP (also fixed).

Either of these mean that an attacker could MITM your `gem install` or `bundle install` and give you malicious gem contents. You'd be owned when you required the gem -- possibly sooner, in fact, because gem install itself provides mechanisms for arbitrary code execution.

It's also important to note that RubyGems does not default to HTTPS. I highly recommend using `source "https://rubygems.org` in your Gemfile and the following in your ~/.gemrc:

:sources:
- https://rubygems.org
There is a lot of truth in this article. Most things I remember are bits of information I have had to tell others about.
Maybe schools should adopt this technique for helping kids learn?
hackerleague post: http://hackerleague.org/hackathons/hackru
This is a big deal. iiNet was picked because (at the time) they were a smaller ISP and wouldn't have the resources to properly contest - as leaked in a Au/US cable. Fortunately they did choose to contest and are (largely unrelated - a series of strategic acquisitions) now the second largest ISP in Australia.

Unfortunately, AFACT's strategy now appears to be lobbying for changes to copyright law so that they can sue successfully.

Add Custom Fields To RSS Feed
@ruhacking
I tried those and other location-sharing apps but I couldn't find any that didn't suffer from two problems:

1. They force my contacts to go through many steps, like downloading an app, registering an account, etc. It's hard to get someone to download and setup an app. It's easier to get them to click a link.

2. They force my contacts to share their location 24/7, which I don't need and they don't want. Having users "explicitly provide consent every time" is a feature.

You're right that I should put this in the app description.
Multiple errors, it should be:

jQuery is awesome (is even my nickname!) but sometimes plain Javascript does the trick pretty well.
Here's a crazier version: https://vimeo.com/4041788 The camera takes frames at 30 fps. But each frame is only exposed for 1/4000 of a second, which lets you see the string as if it is holding still during the frame. And finally, the camera has a "rolling shutter" so the bottom of the frame is captured about 1/50th of a second after the top. This creates the visible wiggle in each frame, as the string vibrates several times as the frame is recorded from top to bottom.
Pardon me, but are you by chance familiar with the French word for "shower"?
IMO, when you are in a situation where you have to teach, ultimately you realize that you both know your subject material well enough to help out people who are new to the material even if you might get minor details wrong.
And in the event that you get something important wrong (it's happened to me, FWIW), people know that you are human-- as long as you're willing to own up and figure out where you are wrong (and actually do have a bit of mastery over the larger material) most students are happy to be learning along with you.
The only way to overcome is to actually make mistakes and practice dealing with them.
Fortunately, the more you teach, the more you will find opportunities to deal with your misunderstandings of the world.

This tendency to learn by teaching has also given rise to a class of people who start teaching on their websites and blogs a little too early. They haven't yet got the right intuition, and still try to teach their audience, which leads to wrong assumptions or false answers/ conclusions. Sal is in complete contrast to this, coz he is so well prepared on the subject he is teaching. And he has a depth of knowledge of his subjects which anyone just learning it can't hope to have.

If you're just learning how to code then what could you possibly build yourself that you'd be willing to pay through the nose for?

My point here is that the only consumers that will pay are ones who have an actual business (model) in place and those people are rarely going to be total code newbs.

I can see this as an interesting playground but it also seems overkill to me for a playground.

I agree that in order for this to take off the data needs to be made portable which means they need to opensource all or part of it and rely on their expertise for the business model. That, I could get behind.

Do you have any sort of logical explanation or intuition about your stated result - that 75 percent of tests do not improve business results?

It seems to suggest that design just has to be good enough. Below some set threshold for visually appeal and/or usability the design hinders money-making. However, above that threshold, further improvement isn't necessary? If this is a reasonable interpretation, that is actually quite sad and suggests that all the new design-centered startups are wasting a lot of money.
200x slowdown is only a problem if you're running a script that requires a lot of computation. js.js seems directed at things like ads and other widgets, which often are just doing a bunch of easy, boring DOM things and can in fact still function fast enough to not annoy the user, even with a big slowdown factor.

Also, as they say they just got this working. It seems reasonable to assume that with enough programming mojo, the slowdown could be something closer to 10X or even 5X.

Firebase is a great, especially if you want to rapidly develop or test new things. It's saved us days/weeks of time not having to worry about structuring/restructuring our backend and allowing us to focus on getting the UX/design of our app down first.

This has been extremely valuable for our small team -- we've been using Firebase since the beginning and are a big fan of the technology. By abstracting this part of our product away for the short term while we build and iterate, it's probably doubled our productivity - just in the short term, of course (and assuming it would take half of my time/focus to be building/maintaining backend code).

Plus, James and Andrew are always super responsive whenever we bug them for stuff.. they know how to keep their users happy.

Fundamentally, it's just a result of picking up certain attributes of the language more quickly than others. That could be a result of the particular teaching method that Pimsleur uses, or just the natural abilities of the student.

I've had a similar experience to the grandparent while learning Mandarin (not through Pimsleur), where my pronunciation has far outstripped my progress in listening, grammar, and vocabulary. Hoping to remedy this through different exercises, talking with (sympathetic) native speakers, and catching up on my Chinese soaps. ;)
