They don't get "hotter" overall. The problem with LEDs is that most of that waste heat is produced in a tiny element - the actual LED chip - which is difficult to cool down because you can't surround it completely with heat sinks. The meager heat sinks you can put on the back of the chip are not so well connected thermally with the environment.

A CFL has a much larger volume to produce that heat, and a much larger surface area to radiate it; and even if it got very hot it wouldn't care that much. A LED is a tiny speck of semiconductor that bears the brunt of a lot of energy, and it's not rated for operating at high temperature.

It's like normal sunlight warming up the palm of your hand versus sunlight focused to a point by a palm-size loupe - it's the same total energy, but one is nice and warm whereas the other can cause serious damage.
That's a great point, thanks! Should people actually start using it, I'll definitely consider investing some more time in it.
Another nice thing about bridge is that most tournaments are open, and even if flighted you're almost always given the option of "playing up". I, as a serious amateur have had the chance to play against probably 3 of the top 10 players in the world, and anther 10-15 that are probably top 100. I'm not talking exhibition games either, like a chess simul, but actual tournament play.
Geoffrey Moore covers this in Crossing the Chasm [1]. He basically suggests that you have to specialize in an industry vertical to get beyond the early adopters and into the masses. Once you cross enough verticals, then you can come back and be a more general product.

I've also heard YAGNI [2] shouted at generalizations. People can spend too much time generalizing problems for broader application that never comes. I don't know the right answer here, as it seems hard to measure how likely it will be that any generalization will be reused later. Perhaps it's ultimately judgment.

This is a great marketing stunt!
By your logic, we should have not banned CFCs in household goods but instead made them more expensive.

The reason for why we want to have energy efficiencies is simply because we only have to produce so much more electricity to power everything else. We have not reached a point where nuclear, solar, or wind is cheaper by the MW than coal and as a result we'll continue to build those for the foreseeable future. Banning inefficient and obsolete light bulbs will prevent us from needing to burn more coal and other harmful fuels.

If we didn't have this problem with electricity generation then banning something may become less desirable.
I've been teaching, middle school and high school, for the past 15 years. I have always had a stash of chess sets and clocks in my room. They see pretty consistent use.

I love chess in schools for a number of reasons. One of the most interesting things about watching chess in schools is seeing who rises to the top. The best players tend not to be the brightest academic students. The best players tend to be smart kids who fight some of the bs that schools make kids endure. These kids are smart enough to 'get' chess, and have enough fight in them to stick out the difficult moments in games and tournaments that separate the best from the really good. These are the kids who tend to get in trouble a lot, who get bad reputations among teachers. Watching those kids show everyone up by winning chess tournaments soundly against the brightest academic kids is pretty awesome, and can be life-changing for some students.

I love teaching chess because you can teach anyone some simple ideas such as opening strategies, piece values, and simple endgames, and they can then beat anyone who hasn't learned those concepts. Kids who never thought they could learn a "smart person" game like chess suddenly play well, and start to realize they can do intellectual things. Then you start to see natural talent come into students' games.

Playing chess with kids is fun! If you have the chance, introduce a kid to chess.

> But the fact that early adopters are psychotically rich for doing nothing is... one of the many signs of a flawed system.

No they risked their money with a speculation that had almost 0% chance of getting any return in the future. They took a huge risk, without this, bitcoin would not exist. And that's why they are rewarded: Taking a risk that almost no one would have taken to create something big.

> Basically if everyone started selling the market would destabilize because supply/demand curve would change & I'm pretty sure the value of what they're selling would plummet before they can unload most of their stack.

Bitcoin had already 2 big crashes (one time from $30 to $1-2 and one time from 200+$ to under 100$) and still recovered afterwards because there's people like me who see the potential in bitcoin.

And please tell me what your "real value" exactly is, because in my opinion their is only a perceived value for everything in the world.
Apologies, I wanted to validate the idea before I invested much more. I will surely improve the design moving forwards.
I think that's it exactly.

For the many websites I've built I noticed that the biggest problems arise when the decision is made to do things in a 'custom' way. Custom back/forward functionality, custom scrollbars, custom 'widgets', and so on. Again and again it turns out more complicated than initially thought, and relying on the DOM and native interface elements would've been quicker and less error-prone.
Just marketing IMHO. You say you'll accept bitcoins and then you'll have 10s of articles talking about your company.
First, I agree that using an OSS portfolio as a hiring filter is sure to reinforce existing privileges. But I do find articles like this which try to attach a stigma of oppression and exploitation to OSS as a concept rather distasteful.

In my personal experience as a (white, male, etc) OSS developer, the software I'm writing from my privileged position is used by and contributed to by lots of people with non-white and/or female names. As such, I believe the fact that I'm able to do my work (and derive an income from) OSS rather than commercial software, and thus reduce both the financial and the cultural barrier for people who want to use it, acts as a (minor) privilege-equalizing force from the perspective of users.

Self-congratulatory OSS circle jerks (which are indeed kind of common) are dumb. But the very fact that a field is dominated by privileged groups does not automatically make it evil.

That's not an excuse. You seem to have an ignorance about a whole group of people. I'm fairly sure even the Pope could come up with the word "transsexual".

I don't mean to imply that ignorance implies anything else about you, but it's ignorance. You can alleviate it by:
1. Meeting some people outside of your apparently somewhat homogeneous bubble
2. Reading books

I don't find too much to disagree with in the observations made in the post, but I'm not sure what useful conclusions emerge. It's clear that women are under-represented and this needs to be addressed. The OP doesn't really suggest how this might be done and appears to be more interested in assigning blame (which is not actually particularly Marxist thing to do; after all, it was Marx who said that "the philosophers have only interpreted the world in various ways - the point is to change it").

Beyond that, I'm not totally convinced by the argument that women are incapable of leveraging unpaid work to gain future economic advantages. The last 50 years has seen a massive increase in the number of women doing this - work done towards a degree in a university is not only unpaid, but you actually have to pay for the right to do it (in many countries). Despite this, the proportion of degrees awarded to women has consistently increased and in many countries there are now more female graduates than male on an annual basis[1]. The argument that women are capable of passing 3-4 year degree courses but incapable of maintaining a Github account needs some further explanation.

As a cis/hetero/white/male human, my opinion has always been that, yeah, life is pretty awesome. Open source software is great and I'm hugely empowered by it. However, I genuinely would wish to see those benefits extended as widely as possible, and open source software has the potential to be a good tool for this purpose. FOSS does lack formal barriers to participation and the culture is still young and malleable. One of the things that the OP does is attack the rhetoric of open source, on the basis that claims to "openness" or "meritocracy" (not mentioned in the OP but often raised in these discussions) are misleading. I would accept that but I think it would be best to see this as a failure to live up to our ideals rather than as a deliberate obfuscation that masks the hidden agenda of oppression. If we want to challenge hackers on their behaviour, point out that behaving misogynistically is un-hackerish, that our commitment to openness needs to be backed by actions, that our values are best served by giving everyone the best possible chances to thrive in our community. The OP takes the view that the straight white men of the tech industry are perfectly happy with excluding those who are unlike them, to which my initial response is unprintable on a family website and my more measured response is that this is a blanket assertion that does not match my experience. It is certainly true of some people, but I think it would be better to isolate and exclude them, rather than start from the assumption that they represent the mainstream view of the community and that hacker culture is inherently sexist.

Since computers play chess (better than humans) by looking at moves and ranking them as advantageous or disadvantageous, I would think it would be relatively straightforward to use a computer to decide whether a move is a mistake or not.

There is no law that you cannot produce a car without a seat belt on every seat. But there is a Ministry of Transport approval that is only given when your seats all have seat belts. According to you the people should be able to define how many seats need a seat belt. Wrong.
It's difficult.

The CFL has a huge volume and a huge radiating area for the heat, and that area is well-connected thermally with the environment. Plus, it can operate at higher temperatures anyway.

The LED active element is a tiny chip of semiconductor material. All that heat is dumped in a tiny volume, and you can only put a heat sink on its back. Plus, the heat sink is close to the fixture and therefore necessarily hampered in its function.

It's not an easy problem to solve. If we think pie-in-the-sky solutions, perhaps a re-design of the connectors and fixtures might help - if you made a connector that was designed to take heat away from the bulb, that would help a lot; the whole fixture would become the heat sink.

It might not be that helpful, but you can actually download the JavaScriptCore source directly from the WebKit trunk (http://svn.webkit.org/repository/webkit/trunk/Source/JavaScr...).

It's pretty ironic you used this picture, since she got a lot of negative press for it, and she mostly used it to promote herself and her blog.

Women are already under enough pressure in society to look "perfect" and this picture shamed them into not looking like the model. So women software engineer are supposed to spend tons of time at the gym to look like the model. They already do most of the child rearing (as well as house keeping and errands), and on top of that in order to get a job they are required to code in their spare time just to get a job.

I live pretty far away from my parents (about 200 miles), and my dad is in poor health. He almost died a few months ago. I spend a lot of weekends visiting because I don't think I have much time left with him. Yes, that is my choice.

JSC was always there for years in WebKit source repository, and anybody could build native JSC engine. Well, it needs some extra works, but there're also some Github repos from other people.

AFAIK, the only difference to Safari was JIT compilation support. Because iOS doesn't allow executing dynamically generated machine code in 3rd-party apps for security reason.

Does iOS7 support JIT compilation on JSC embedded in any app? If it supports JIT, that could be a big news, because it means Apple finally allowed dynamically generated code in 3rd-party apps, but I don't think the day will come.

And personally, I don't see any benefit from JavaScript apps. If someone claims JS or any third party frameworks are better than Objective-C for iOS app, I would like to ask these things. (could be offensive, but these are actually how I feel from those claims)

Does it offer better auto-completion? Does it offer better syntax/semantic/type checks? Does it offer better debugging aid? (like GDB's execution rollback) Does it offer better accessibility to any platform features? Can I use new features immediately? Shouldn't I wait for 3rd party patch? Profiler for device and simulators? How's low-level access? If I have some trouble, how can I fix it without knowledge for lower-level (Cocoa/Darwin)? If I want to use C-based DSL? Is it safe for AppStore approval? What's the benefit of using open language on proprietary platform?

I mean, what's better with JS than Objective-C with Xcode?

If it can't offer any of those stuffs, it means it's at least 10 times less productive = 10 times more cost.

Well, it could make sense JS app for an Android app because ADT is too sucks so some extra wrapper can bring extra productivity. But for iOS, JS stuffs only degrade productivity by extra abstraction, debugging hardness and inferior toolsets.

Oh man, Shoutcast brings me fond memories. There used to be some very good (albeit illegal) show providers like EveryShowSucks (ESS). The nice thing about the shoutcast model, is that you could just tune into a channel and consume whatever was available (knowing it was going to be good).

It is something that is not available in the Netflix-es, and Hulus of the world (and something that Cable still has).
I agree, but just wanted to add that if you find Go boring, I suggest you pick up a good Go book or two. The really good Go writers can construct an entire war narrative from a game of Go, all the while giving you deeper insight into the strategy and tactics at play in the game. To be honest, compared to Go writing, I find much writing about Chess to be very boring and analytical (though I'm sure that has as much to do with specific authors as with the subject matter in question).
I think you are confused.

The original assertion was (basically): "Just because you make something part of the law, doesn't make it free".

Note it was not even an assertion made about german law, but the law in general. There was no support for this statement offered, just a bare assertion that this was true.

I pointed out this was not true in the US, and probably not true in plenty of places. I specifically asked if there was any caselaw to support the assertion.

The response, rather than to offer support for the bare assertion, was to point out i cited the US. Which was kind of besides the point.

So I went to the trouble of looking up german copyright law, and posting what it says about it. At that point, I felt like I was essentially doing the work of the parent for them, and pointed out again that maybe they'd like to support their still bare assertion about the law.

So yes, there was something to support, and at least as of this writing, it's still not supported.

How are you getting the data? As far as I know, the dispensaries don't have APIs, so are you just going in and scanning their menus every day? This is actually pretty useful in that you can then comparison shop different dispensaries.

Meanwhile, it will be interesting to see what the federal legal response will be to the various medical cannabis related startups i've seen popping up. In general, it looks like the road to legalization is pretty open (well, if stoners voted and orange county didn't...), but production and distribution still need to be addressed if you're really going to remove the criminal element (which you should).

Anyone know anything about the current legal climate around cannabis in California? Specifically, increase/decrease in raids/legitimacy/rules of/around medical dispensaries and current situation wrt supplying them? Still seems to me to be totally fubar thanks to otherwise unemployable crazy old people...
