This singlehandedly resulted in a company I was associated with not going public [March, 2010], when we had to take millions of dollars in write downs associated with our devices (which had some of these flakey capacitors) failing in greater than expected rates. I don't think it's an exaggeration to suggest that this problem materially changed my life, and altered the careers of many of those who were in our Manufacturing and QA departments (for the worse)

I also spent the better part of 2003-2005 replacing Dell Optiplex GX270s that had failed motherboards - bulging capacitors - almost 50% of our desktops were turned over.

Plague barely captures how bad it was.

Minor nit pick:

"The second, and this probably goes without saying, is that data is actually stored in the compilation using hexadecimal. "

It's stored in binary, your just using an editor that displays the hexadecimal representation.
That is a really good point. I seem to remember a really interesting article posted to HN awhile ago that went over all the pitfalls in depth. I'm really wishing I had bookmarked it now.

I think I'm going to have to rewatch the promo video in depth to see if they have any unrealistic demos with glasses-wearing users.

I still believe this technology would be really useful for doing Real Work. You could get around the shadow problem by working in a black surface. I am imagining an interface with a black drafting desk, small bluetooth keyboard, and a 3d tracked pen with this AR display could be absolutely revolutionary for certain engineering disciplines.
AFAIK Spamhaus does not accept spam reports directly:

Okay. Yet another hardware Kickstarter with egregious claims? No, thanks.
I think that claim is actually accurate. The Oculus Rift is much different: it's virtual reality, whereas Meta is augmented reality. They are different things, and augmented reality is much harder. The Oculus Rift completely occludes your entire field of vision and replaces it with something else entirely. Meta modifies the real world with virtual objects.
Don't apologize too much. I was having fun demonstrating
how to track this stuff down. That said I would have
been really upset if I had donated a significant amount
of money to the EFF and then they decided to give all of
it away.

BTW it is probably possible to verify that the money
donated was REALLY send to the bitcoin faucet.

Oh and yeah I got my first bitcoins from the faucet like
many of these other people. It was an important service, however given how bitcoins can be split up it didn't need to be giving out large amounts at all.
That, and breathing is nice.
You can measure acceleration without needing a special frame. More significantly, you can measure rotational motion without something to measure against.

My aunt has a story about this: one time she listened to a Feynman talk on tape. Afterwards she was explaining it to her son and she started to draw out some diagrams that Feynman had been drawing on the board during the lecture. Her son said "Wait, weren't you just listening to this? How do you know what the diagrams looked like?" She realized that his explanations were so clear that she had been able to picture everything without even consciously thinking about it.

This doesn't strike me as bragging at all. I always appreciate the chance to connect people with projects.

I have learned from some of your posts about developing with Django, so I took a second look at the site after realizing you had helped build it.
So you're saying that what laymen mean when they intuitively understand that you can't measure your own motion is something else than what is meant by a physicist in the context of relativity. In particular a physicist means that you can't do that even when you have access to light, or those other things. A layman understands that you can't measure whether you're moving without access to those things, but he does not understand that it's still impossible with access to those things. In that case you cannot appeal to layman intuition on the former to conclude the latter, which is exactly what's necessary for an understanding of relativity.

Also, even with this interpretation it's questionable. In Aristotle's mind you can determine whether you're moving or not, even if you are completely alone in the universe. You take an object that you have with you (e.g. your t-shirt), throw it in a random direction with a specified velocity relative to you. According to Aristotle both you and the watch will decelerate. But since the deceleration is relative to the absolute reference frame in which you will eventually come to a halt, you can deduce whether you're moving from the relative deceleration between you and your watch (although interestingly if the deceleration has a special form, then you cannot determine whether you are moving, but that is again a non trivial fact that is not obvious to a layman). To Aristotle, and the people after him until Galilei, the idea of a special reference frame was perfectly intuitively obvious! (though, of course, incorrect)

I'm 28. My focus sucks overall, but a recent improvement I've made is the type of music / noise I have while working. I switched from music I really enjoy and tend to sing/hum with, to electronic music with little to no vocals and upbeat tempos. My mind focuses less on the words and music, and allows me to think more about what I'm doing.

I've also tried some white noise creators, like this one for coffee shop sounds: http://coffitivity.com/ Personally the techno music works better, but you may be different.

Awesome, thanks for the reply.

It may not have been something which you wanted to do, but I think it is a really interesting problem, and I bet it has been rewarding for both business, and in a pure engineering sense.

In some ways, I think about what it must have been like to create a fake identity in a less connected age, and I wonder at how it will continue to evolve.

I recall some Doctorow novel in which spam and its increasing sophistication was almost an escalating arms race between our ability to distinguish authentic interactions versus those that were staged or generated / general sock puppetry.

I am curious about additional signals and information, I would presume in addition to fingerprinting and collecting as much information about each of their implicit touch points, did you find yourselves increasingly relying on more traditional manifestations of identity/reputation, etc.

edit: Or I wonder about a discount for new sign ups with a one time facebook scan & score type mechanism :D

Thanks again for sharing more information, good food for thought!
Great! You just simplified the experiment!

Dropping something was only one idea, but feeling pressure is much simpler.
No, you’re saying that filtering people == having a call to action.

That is a false equivalency.

I’m also not sure if you are attempting to attack me for only discussing Google. Of course I consider my criticism to be broad enough to apply to similar situations involving other ad networks (and to Facebook), but we are discussing specifically Google’s privacy policy.
One of the first video lectures in Coursera's Machine Learning course, Andrew Ng gives a pretty similar explanation why he chose Octave as the language for the course; in his experience, students get more done in Octave than in any other language he has tried teaching with.

Thanks for the tip!

I need to be clear that the ASP.NET implementation that you see in Round 5 was contributed by user @pdonald at Github.

That said, we'd be happy to receive more pull requests with ASP.NET changes and improvements. We suspect there is a lot of room for improvement in the Windows numbers.
The easiest method is to design a web page, then see if you can actually build it so that it displays as expected across various browsers. If you find you cannot, then adjust the design with what you've learned and try again. Eventually you'll learn what works and what doesn't. Once the limitations and advantages are understood then the design part is much easier.

The equivalent is for a print designer to design something in Illustrator for a certain size and type of paper and never actually printing the design on that paper to see how it turns out.

I'm in the school of thought that a web designer should know HTML/CSS and how browsers render those elements as a web page. They don't necessarily need front-end developer level knowledge, but if they don't at least know the basics of how browsers work then they'll always try designs that are not workable.

Personally, if I ran a web design curriculum, I would require HTML/CSS education first, then start on design. But it's often the reverse, or worse in that designers are taught all kinds of different avenues of design, but web design is that kid in the corner no one picks for dodgeball. I've interviewed many a designer with nice school projects but not one web project in the portfolio.
Wordpress has shockingly bad code for how often it is used.
The glasses are not a normal display. Most displays are opaque, and can display pure black by simply not emitting any light. These glasses are transparent, so when they don't emit any light you see whatever's behind the display, not black. Displaying true black on a transparent display requires an extra element which can selectively block incoming light. These glasses don't have such an element, and cannot display black or dark colors unless you happen to be looking at a black object in the real world.

The 3 Secrets of Highly Successful Graduates
Well, I must be very confused, then, because I don't see where the input comes in given just the s, k and i combinators. (The Jot programming language, which can be translated into SKI, for instance, doesn't do input or output. You want the Zot variant for that.) How would one write a program, using just s, k, i, and application, that takes the name of a file on the command line, opens it and reads it in, then prints the lines in reverse order to stdout?
Is it me or did the Google I/O keynote really suck?
Only people applauding were employees in the front rows. Presenters saying "thank you" when there was no applause. All catch up products and smoke and mirrors.
Here is my answer.

App.net has positioned itself as "anti" - capturing the developers who were turned away from other social networks. That's OK as a starting point, but it doesn't account for growth to 100k users. So who are those users?

And I think the answer is: they're users that would have done business directly with the outcast developers and their products, rather than App.net. App.net is a new kind of middleman.

There are types of social networking services that would be suitable for subscription fees, and ordinarily each of those devs would have the option of building out their own infrastructure, or trying to cram their idea into the second-class citizenship of a Facebook or Twitter, with all the risks that entails. But hooking themselves to App.net gives them a mix of the two options - more freedom, less bootstrapping.

So there's a massive positive feedback loop associated with getting developers on App.net - the same kind of feedback loop that made Microsoft in its best years so developer-centric.

The downside is that everyone's going to be heavily locked in. The endgame for this ecosystem isn't likely to be pretty.
There is at least one U.S. military contractor whose main line of business is reballing RoHS-compliant SMT components with good ol'-fashioned leaded solder. Because the military depends on electronics that HAVE to work, for a long time, in hostile conditions, and could give two shits about the environment. The Army fires depleted uranium into the earth, you think they care about a bit of lead?

1) Your original post I responded to was talking about oculus rift; while it may be possible to use the oculus rift outdoors or untethered, it's definitely not currently being developed for that use case.

2) FWIW, world lens is described as augmented reality. Also, it has a much narrower FOV, probably doesn't update in real-time (and probably doesn't need to), doesn't require wearing a bulky headset, doesn't occlude your entire FOV, and in any case, is not connected to an oculus rift.

Air pallets and unit load devices for aircraft are also pretty weird; they're specific to aircraft, and to specific locations in the aircraft. I guess there the labor vs. fuel-per-weight/cube thing tradeoff is a lot different than with ships or trucks, but it's still really inconvenient (plus, "air force pallets" (463L) are super expensive, corrugated aluminum)
I have to wonder how accurately you could tag spammers using sentence structure and spelling analysis.

I don't see why it would be impossible; it'd just be pretty hard. What if you had another layer of glass that was like those old LCD calculator screens that have opaque numbers, but can otherwise be transparent? Maybe you could display things in front of those to have full opaqueness. That wouldn't help with variable opacity though.

Dropping an object that won't get accelerated is one way to measure acceleration, but not the only way. If you are the actor causing the acceleration on yourself, as I originally intended, then presumably you already know / measure-by-doing how much you have accelerated, and you can use dead reckoning to watch the earlier reference frame fly by.

If the force is external and doesn't apply pressure then you have to drop an object.

If the force affects the entire universe the same way then that's aether and can't be measured / doesn't exist. But that was not the kind of force I was using to disprove "you can't move".

Ask HN: Tour guidebooks for business travelers
Recently as I have traveled a lot through my local airport hubs (Orange County, CA and LAX), I find myself giving a lot of restaurant and things to do recommendations for business travelers visiting the region.

There are a lot of tour guides for regions, but would any of you be interested in a tour guide book/app for a given airport?

So say you are a business traveler flying into LAX, you would get a tour book specifically geared towards business travelers. So for example, it would highlight restaurants good for after work, and activities good for the weekend. Ideally it would be customized per airport region.

Things the guidebook would omit would be sleeping accommodations because the assumption is that it would already be booked through a business traveler's respective work.

Any thoughts on this?
A pure Go MySQL driver is being used for the Go test. OpenResty probably uses a thin wrapper around the C library.
Any one of us can work out x by x plus y by y plus z by z less c by t by t where x and y and z and t are each part of how to get from one "here and now" to a 2nd "here and now". I can try to tell you what c is or we can just say that it is one (i.e. c by t by t is just t by t). And the math that we do will work out the same if I work it out from what I see or if you work it out from what you see, even if I do not move at the same rate as you.
To be fair, they're probably not aiming at the Earth.
And this is a great way to lose your best talent. Why work for a place that puts you through bullshit tests when you can work for a company that gives you important work and helps you succeed from day 1?

Personally, I did achieve significant success in a highly bureaucratic environment and got rewarded for it...but then I left anyway to work at a place actually encouraged me to work on problems that mattered, instead of constantly getting in the way when I tried to get anything done. Any sane person would do the same thing.
Some systems do work, it's just that it often leads to you being politely asked to leave and never return.
I'm aware of one major consumer electronics device which was redesigned at the last minute for RoHS solder, leading to very high failure rates.
The reuse of shipping containers is becoming a rather trendy thing. There are many projects for the 3rd world, and many design/architecture projects for the 1st world. I don't think containers make good building materials, for many reasons not worth listing here. One additional critique is that the reasons for taking a container out of circulation (damage, corrosion, pollution) are exaclty the reasons you wouldn't want them for construction. So for construction, you have to buy a working container (especially if you want to ship it as a kitchen to the 3rd world), so building with containers is not recycling but more like buying an alternative construction material.

Also, I wonder how good it is for local cultures to have religious organizations parachute food and foreign religion into their communities. That whole "teach a person to fish..." thing.

You're right, an extra LCD layer could definitely do it. I'm just saying that the specific glasses being used here don't have this capability, unless there's some enhancement Meta isn't talking about and isn't showing in their videos.

I've had a bank account and associated credit card with HSBC in the US for about 5 years now, and I only got an ITIN about 6 months ago. I managed to get the account because they offer a service for Premier customers where you can link accounts in different countries together, and I already had an account in the UK.

However, over the years it's been a massive PITA to maintain since I'm not a resident, and it's getting progressively more difficult - in fact I just moved all my money out of the US to a USD account in a more friendly jurisdiction (New Zealand, where I currently live) because it was getting to the stage where I could see them possibly freezing my account and it being a pain to sort out. I suspect I wouldn't be able to open the account under the same circumstances now.
In the 90's right before ND was part of PowerBall, I was asked to buy the tickets for a whole office because I was going to MN. I bought $120 of tickets and did not have one ticket with any winning numbers (never mind a powerball). I was never asked to buy tickets again. I seem to remember the odds were better to win than miss all (5/49 + 1/42 era).
