My understanding is that it's not so much a filter as a retransmitter layer. The LEDs give off a rather small spectrum of light that's quite harsh and the yellow "filter" takes that energy in and fluoresces out of a wide variety of wavelengths of light that are much more pleasant. There's most certainly a loss of energy because of the conversion, but it's not filtering out wavelengths like normal light filters do.
Bagcheck had so much promise :(. The UI was so elegantly designed and there are still bits of it that I'm trying to pull apart for my own designs.

At the end of the day though, the engagement just wasn't there. You would go on there a few times, check out a couple of bags, maybe create one or two and then never come back. It's sad it didn't work out but the founders are all insanely talented people and I'm sure whatever they go on to do next, it will also be awesome.
Well the bulb shape is really a relic from the past. The design has already been disrupted with fluorescent lights, that brought bigger cylindrical shapes that diffuse more.

The good thing about random altruism, i.e. giving stuff to people regardless of whether they need it or not, is that it doesn't encourage welfare dependency.

When you give free stuff to "those in need", you have to be extremely careful not to just wind up changing the balance of incentives in a way that just encourages them to stay "in need". Otherwise you're harming them, not helping them.

Roger Penrose's "Road to Reality" is great for an overview in one not-so-compact book. It's a bit hand-wavy, admittedly. The neophyte problem, and reason we have universities, is that "you don't know what you don't know." Penrose's book and t'Hooft's curriculum get you some part of the way to knowing what you need to know.

One more option is Lev Landau's series. They're dense but fairly readable for graduate-level tracts.

It might look like this: http://www.adafruit.com/products/357 - Buy your lighting by the foot. 12V DC may make more sense for homes these days than 115 AC. The incandescent bulb was the "killer app" for a whole power ecosystem. In older houses in places like San Francisco you sometimes find wiring going through the old gas lamp lines.

Are there standards that govern exactly what constitutes an AAA vs an AA? If so, who makes those standards? S&P? A third party that oversees all these organizations? If the standards are vague, then it's all subject to interpretation. One person saying it's AA might be the same as another saying it's AAA. S&P isn't giving a perfect rating to the USA... because the USA debt situation isn't perfect. I mean, we judge human beings the same way - noone's perfect. Why should we be any different towards the USA? Just because it supports democracy, has an emotional national anthem, and has a rich history? NO.
SRP is cool stuff, but if we're going to do SRP I would be more interested in doing it right.

I think that would mean having browsers support a standard SRP protocol binding (eg http://www.ietf.org/rfc/rfc5054.txt) and then really nailing the browser user interface.

I could see using SRP as an alternative to private keys, or as a strong "something you know" factor in addition to private keys (a "something you have" factor) in order to establish ownership of an account.

However, this doesn't strike me as a credible first step in getting through the aforementioned "deployment deadlock" issue.

If the assumption is that homework and tests are designed to help the student learn the material, then subjective grading is very beneficial. For example, there are ways of solving math or comp sci problems (including simple "typos"), especially when you don't understand the rules properly, that will give a correct result, for the wrong reasons.

I would much rather a math or computer science teacher be looking through the process used to find the answer - and providing constructive feedback.

Just getting a quick yes/no response back seems a lot less helpful to me. I don't know how much the human graders mentioned in the article actually do in terms of feedback, but I imagine we're still a ways away from a program having insight into WHY you chose the wrong method or made the mistake you did. The program can't help tailor their teaching to help set you straight.

Of course, my view on this is likely clouded by the fact I went to a small school with small class sizes throughout. When you only have 5-20 people in each class, direct professor engagement happens. If I had to deal with TAs, I don't know how I would feel about the matter.
Who the hell is this guy? Thoughts on being a career VC
It mostly is separated anyway, with TAs doing the grading and professors doing the teaching. Of course, you could further outsource it from TAs to a 3rd party, but TAships have the dual role of funding grad students, so it might not save the university money to get rid of them, if they still plan to support grad students to the same extent as currently--- they'll have to find some other way to funnel that money to them. Of course, it might be part of a plan of reducing grad-student support.
Ask HN: I want to open source a project, but my company has a problem...
The company I work for requires that all employees submit a request to work on open source projects in their free time (Washington state has no laws that prevent such behavior by corporations).

They've given initial approval, but they have issues with one part of what I want to do, citing potential patent infringement. They suggested that I submit several mock-ups of the potentially offending project and they will pick a few that don't have any patent conflicts. They can't disclose any information about the patents since they haven't been granted yet, and they can't just tell me not to do it a certain way.

I can't go into details about the specific part that faces potential patent issues since I don't want to jeopardize my project or my job.

My question: should I submit mock-ups for approval and deal with any restrictions that arise as a result or should I just keep working on the project in my free time, but not open source it until whenever I choose to leave the company? I won't leave for several years unless the project gets really popular. I have already verified that this wouldn't be an issue if I wasn't an employee of the company (I asked the patent lawyers "So if I did it in a way you didn't like, could I just quit and that'd be the end of it? -- Yes").

It sounds like you have an awesome lifestyle, but I'm not sure I agree with your definition of a vacation.

For me, the new definition of a vacation is being completely unplugged. Granted I don't have my own business yet, so presumably daily check-ins are OK/necessary - but even then I'm not sure I could properly 'disconnect' and relax.

It worries me that even for relatively low-level staff it's not uncommon to get email responses when they're "on vacation" nowadays.
I'm with you on that, but the concept is a good one albeit not widely adopted. I've only created on bag, but I still peek in there now and again to see what other people are putting together.

That being said, Luke is a talent no matter where he goes and hopefully he'll bring about some good UX to the poorly-designed Twitter front end.

The essay-grading software I've seen described in enough detail to figure out how it works has a heavy bias towards enforcing specific structural rules, while mostly missing "quality of argument" type questions. So a student writing to exploit its bias would want to worry more about formal structure: essay organization, correct grammar, use of certain "must-have" keywords, etc.; but worry less about things like avoiding logical fallacies in their argument, because the software won't notice those.

Facebook - Fails in privacy once again
Over the last week I've been working on a project that uses Facebook API, and here's what I noticed. If you blocked somebody, or setup your privacy settings so that your don't appear in Facebook search, or have your profile photo hidden from the search, then you are not completely protected.

(1) Using the Graph API everyone can go to http://graph.facebook.com/#{user_id} and find the basic information about each person on facebook.

(2) Then, using the same API you can gain access to that user's profile photo, regardless of their settings:
http://graph.facebook.com/#{user_id}/picture?type=large

What does that mean?

Although time consuming, technically anyone could iterate through the list of all Facebook users and then by comparing names to the photos, search for targeted users' IDs. Can the bad guys do anything with those IDs once acquired? Let's hope not, but I wouldn't want to find out.

The author misses the goal of A/B testing: it's to improve a measurable business objective (signups, retention, etc), not to pick a more aesthetic design.

As confused as this article seems, it does at least reference one Actual Paper: http://arxiv.org/PS_cache/arxiv/pdf/1101/1101.0931v2.pdf

I haven't had a chance to look through it yet, but here's the abstract:

We propose a deepening of the relativity principle according to which the invariant arena for non-quantum
physics is a phase space rather than spacetime. Descriptions of particles propagating and interacting in spacetimes are constructed by observers, but different observers, separated from each other by translations, construct
different spacetime projections from the invariant phase space. Nonetheless, all observers agree that interactions
are local in the spacetime coordinates constructed by observers local to them.

This framework, in which absolute locality is replaced by relative locality, results from deforming momentum
space, just as the passage from absolute to relative simultaneity results from deforming the linear addition of
velocities. Different aspects of momentum space geometry, such as its curvature, torsion and non-metricity, are
reﬂected in different kinds of deformations of the energy-momentum conservation laws. These are in principle
all measurable by appropriate experiments. We also discuss a natural set of physical hypotheses which singles
out the cases of momentum space with a metric compatible connection and constant curvature.

"I'd be interested in seeing what lightbulbs looked like if we designed them from scratch today"

The problem is that humans have coevolved with both sunlight and fire. While the shape of the lightbulb may be arbitrary, I think the fact that they provide uneven lighting and cast all sorts of shadows is probably necessary for good mental health. (Because it provides more sensory stimulation, and more closely mimics the natural environment as compared with what you would get from evenly distributing LEDs across the ceiling.)

HTTP auth has literally nothing to do with where the backend code for authentication lives. In our forms-auth world, there already are quite a few authentication libraries.

I just disagree flat-out that HTTP authentication would have done anything to make the problems this guide is trying to grapple with easier. And in the meantime, HTTP auth as it exists in the standards today adds problems.

10-Year-Old Hacker Finds Flaws in Video Games‎
For all the complexity, it's a lot more efficient. Some of the complexity problem comes from adapting LED to design decisions made for incandescent AC lighting in the switches, dimmers, sockets, and power supply. If it were worth it for the user to rewire their house, they could likely get overall simpler and more reliable LED lighting.

There's a parallel to software design, one often incurs complexity when optimizing or adapting one software approach to another. The system might be more reliable overall if you can re-align the entire design, but there's a cost involved in it that might not make it worth it (particularly for physical things with replication costs).

You're confusing REST (an architectural style) with HTTP (which defines the verbs/methods). REST isn't only HTTP, and HTTP clients are not only general browsers.

But it's true, you can't use the full range of HTTP verbs using normal HTML, and that's a shame. Apparently HTML5 was supposed to support them, but it was removed.

I actually think it'd be a good idea for education to become more learner-driven, but I agree it isn't a good idea without more changes. When you combine "consumer-based" education with an education system that is heavily oriented towards just-get-the-credentials, that's what makes it unworkable, because then what the customer really wants is just the credential ASAP. For learner-driven education to work, the learner (or "consumer" if we must) has to genuinely have things they want to learn, along the lines of what constructionist education, Montessori, unschooling, hacker culture, etc. try to aim for.

The technological choices are the obvious ones. Should we build on this platform or that one? They're probably not the highest priority in the grand scheme, but their effects are also most systematically underestimated, I think.

As technologies add leverage the same number of people can do more. So you can get away with hiring less, and run less risk of needing to close down divisions. Or you can raise less money and run less risk of too-many-cooks syndrome in the boardroom.

I'm sure these considerations are more obvious in small internet startups that are struggling to get off the ground. My point was just that you don't need quite the same amount of courage as before because at least a few life-or-death decisions have been taken off the table.

Have you ever sized any 12v wiring? To carry a load of 22amps 20 feet with a voltage drop of <2% with a 12V system requires 4awg wire. That's crazy big and gets very expensive.
