Yes, LEDs will last longer without heat issues. But unless you're running the LED in a refrigerator, that's not a particularly informative statement.

As stated in the DOE that I linked to: "The primary cause of LED lumen depreciation is heat generated at the LED junction." Because it's the primary cause, you can't just ignore it and say that LEDs barely degrade in the absence of heat. You have to consider the heat when calculating LED lifetime.

The stated lifetime on the LED packaging makes a number of assumptions, one of which is that the LED is run at room temperature.
To second hrjet, think of it this way: electricity has to be produced from another source of primary energy, the efficiency of which is very much less than one. So even if electricity can be converted into heat 100% efficiently you are still better off producing heat from the primary source directly, ignoring the cost of distribution. In general the price you pay should reflect the utility of the resource consumed.
Looking at the benchmarks - the A7 SoC is a pretty darn great achievement for Apple! And more than that it is a serious threat to Intel given it is within striking distance of 22nm Bay Trail at 28nm and two less cores!

If they continue this - the next gen MacBook Airs will be running the A8 or even A7x with full day battery life. Intel better have something disruptive up their sleeves!
With regard to bulb life, the big thing to remember about both CFL and LED drop-in replacements for incandescent bulbs is that the electronics do not tolerate high temperatures well, so they're not particularly suitable for use in completely closed fixtures.

Where practical, both for heat dissipation and optical purposes, it's far more ideal to use fixtures which are actually designed around these technologies rather than just throwing retrofit bulbs into crappy incandescent fixtures.

I'm really hoping we see more of these sold to the consumer markets. For good quality LED products, you're talking about 50k hour life which makes a non-user-replaceable solution not seem that bad -- some cheap incandescent bulb sockets might start having trouble after equivalent usage.

On the other hand, I'm concerned that we're going to see a repeat of all the cheap low quality products we've seen in CFL-land.
Mainly because "basic income" is just a fancy word for welfare. If you want to be an entrepreneur in Australia, just go on welfare. Sure, you might eventually be forced to get a job, but you can easily live in the zone between having no work, and having full time work, and satisfy all the requirements for receiving welfare. In fact they even have a special program for entrepreneurs [1].

Removing the strings would be extremely costly, since there are a lot of non-entrepreneurs who would rather live off basic income and do nothing.

For a start, I would think a basic level of support would include decent healthcare for his feverish kid that didn't bankrupt the parents.

I don't see why the poverty line or the world median income should determine whether that level of support should be granted or withheld.

Did his kid choose to get a fever? Did he somehow cause his kid to get a fever by choosing the life of a journalist or choosing to live in some expensive American city?
I don't really feel the need to rebut you point by point. Yes, technology will provide efficiencies and excess that can be used to benefit society as a whole instead of a select few. Yes, it is possible to provide these things without forcing someone to provide their labor.

Automation is going to destroy the income of everyone. Unskilled labor? Almost done. Semi-skilled labor? Coming around the corner. Doctors? Lawyers? Code. Are you going to complain that open source software destroys the income of developers too?

I know your type. "I've got mine, fuck you. Get some bootstraps." If you don't like having a social fabric, which includes caring for the weakest among us, Get. The. Fuck. Out.

I never considered video editing a key application for my mobile telephone. Even with the camera, I would expect to take the video on the phone, and edit it elsewhere.
> VMs and interpreters are the essence of dependence.

I find that an odd perspective. If you can rewrite your VM/interpreter from scratch, are you really dependent on it?

I guess I see it less as "use some black-box language runtime to solve this problem" and more as "I will use plain C to solve this problem... by writing an interpreter in plain C for a good DSL to solve this problem in, and then writing the solution in that DSL. But, you know, someone else already did the first part. I'd do it myself if they hadn't, though."
That might happen at one or a few companies, but it doesn't describe the entire software industry or even a large portion. It seems to in some other career paths.
Well, C++ already has a couple of web frameworks : http://cppcms.com/wikipp/en/page/main

http://www.webtoolkit.eu/wt

I'm not sure that's a good idea though. It's hard to fail safely in a language that can fail silently. And failure modes include, not just blatant hacks into the underlying system, but surreptitious insertion that can propagate to all your visitors.

Besides the fact that it's pretty hard to find a decent C developer these days who's also interested in web development, you have a climate that's not exactly conducive to development in it. If it breaks or needs upgrading, will you do the work yourself? If it's that small, then it's probably not something you'd worry about too much, but then it's only on your shoulders.
Great reply! I definitely agree with you all across the board. Video games do represent an interesting location on the Venn diagram of hobbies, in that they can have great storytelling, character development, action, immersion, and emotional involvement, as well as be just plain fun.

I'm also a big board game geek and will probably blog about that in the future. I have bi-weekly game nights at my place and really into the new(ish) wave of Living Card Games like Netrunner: Android. I really love the social aspect, kicking back for a few hours with beers and buds. And then they leave and I fire up my PS3 :)

Or you know. Spend time with my wife and kids. Usually that.
The GPU in the PS4 is, essentially, an Nvidia 7900-class GPU. Anandtech recently did a comparison of old PC GPUs to current SOCs and the results are surprisingly close. I'd imagine Snapdragon 800 and Oscar close the gap considerably. http://anandtech.com/show/6877/the-great-equalizer-part-3/3

edit: I'm stuck in past. This comment is about PS3 not PS4.
Isn't it nice to have the luxury of living when we have the choice of whether or not to take an infant with a fever to the hospital? Our parents/grandparents didn't have that luxury, they had to ride the fever out and hope their family member lived. Options like that are why our society is so expensive to live in today.
At least it's LPDDR3, so it should be faster than iPhone 5.
No, it's not far-fetched, but it means you've fallen to the bottom of the pyramid of disagreement by indulging in ad hominems/character assassination; which while possibly valid in this case, still means you are failing to deal with the many objective points he brings up (eg the quartering of the Village Voice rates paid to the best writers, not him).

How to earn money through job referrals

Exactly correct. A great quote I heard once is "asking a scientist when they'll find a cure for cancer is like asking a mathematician when they'll find a solution for equations."
Doesn’t sensible policy have to be symmetric, like “slightly socialize the gains, slightly socialize the losses”?
Minor correction: A7 SOC is cyclone not oscar. The article was updated. IMO cyclone is a apt name given benchmarks. oscar is name for M7.
Seriously? It's like the author, Adam, and I read a completely different Huffington blog posts. And why the hell does he need to drop the f-bomb so much to grab attention?
I'm at the very end of Gen Y, born 1993 and 19 years old right now.

Adam says 'So take your “revise your expectations! check your ego!” Horatio Alger bullshit, and stuff it.' Are you kidding me? The Huffington blog post said the opposite! It said that Gen Yers should stay ambitious, but be more humble. We need to keep being ambitious, but expect that we need to work very hard to fulfill those ambitions.

Furthermore, Adam is ranting that he chose something he really wants to do and is poor, because his job doesn't pay enough. It sounds like he is very capable and could get a better job if he wanted to. He is expecting that the job he likes to do will make enough money to support his family and lifestyle (whatever it may be.) That sounds a lot like what the Huffington Post was saying too ("career path expectation.")

I think the Huffington blog post is fantastic, and many of my friends could benefit from its advice. At first though, it does seem to bucket and portray Gen Yers unfairly, but the post's conclusions make up for it.
I would say that, because "entitlement" and "right are synonyms.
Then they should charge an ETF that will allow them to recoup their costs and not trump up some imaginary "copyright violation" boogeyman that stops me from using my phone as I see fit.
The article compares Gen Y against boomers. Reality, at least in my world, Boomers had a good deal in terms of pensions, health care, and the like -- but unless those same Boomers were in Government jobs, those pension/healthcare promises are not as rosy as they were purported to be, or they took their early retirement benefits and folded them into risk in to the market. Those that did found themselves in a world of hurt come the late 90s/early 2000s and are now working at sub-optimal jobs in their 60s.

Personally, I've been working since I was 14 and I actually enjoy it -- a mix of pays the bills jobs, projects, and hobbies. My work ethic is best described as puritanical with a dose of optimizing for work life balance (at home preferred over sitting in a car for 45-60min). I probably work more than my parents did, but I don't have kids.

Any success I have is hard one over time, hard work, and being smart about decisions. I've never had a sense of "I deserve X". I don't agree with the article in a number of things, but when I've lead/managed members of Gen Y, there is a general feeling that they desire to advance/have more responsibility than their experience dictates. This is a generalization -- greater than 50% were of that mindset, but there were those in the remainder that were more balanced in their expectaions.

Sure, it is great to be goal oriented and have optimism, but for some of us a track record is more important than professed potential.

In this case, "context" is a convenient excuse to make a broad sensational statement then claim that the obvious absurd consequences of that statement don't count.
Can you provide a citation to this?

> Contrast this with the modern "basic income guarantee" movement, which requires nothing of the able-bodied "poor" yet requires productive workers hand over a good chunk of their earnings

I don't believe anyone has put together how much is going to need to be collected to provide a basic minimum income. Also, if you subsidize energy (renewables), food (subsidized agriculture), and healthcare (all of which is going to benefit the populace as a whole and is therefore a sunk cost), there should be a minimal cash outlay as a basic income.

How to get to 30+ Million Uniques in 18 Months (Upworthy.com)
I wrote a small (~300 line) C program to scrape an email and insert the part I wanted into a Postgres database. I used PCRE for the extraction and ECPG for the Postgres part. ECPG stands for embedded SQL in C for Postgres, and it looks like this:

// Open the storage subsystem.
void open_storage()
{
EXEC SQL BEGIN DECLARE SECTION;
const char* database = DATABASE_NAME;
const char* username = USERNAME;
const char* schema = SCHEMA;
EXEC SQL END DECLARE SECTION;

EXEC SQL WHENEVER SQLERROR CALL quit();
EXEC SQL CONNECT TO :database USER :username;
EXEC SQL SET search_path to :schema;
}

ECPG: http://www.postgresql.org/docs/current/interactive/ecpg.html

My takeaway was that it was a lot easier than I expected, but it was still kind of a minefield. ECPG isn't widely used or highly intelligent, so there are a lot of stumbling blocks despite the pretty high quality documentation. I would recommend hiding your ECPG behind some functions so you only have to run some of your files through the pre-processor. But it is a neat tool and I could see myself using it again.
I'm not sure current benchmarks can really measure the A7 correctly, or if they are at all ready to deal with OpenGL ES 3.0.
As another point of reference, I have a ProLiant Microserver running FreeBSD with 4x3TB drives in RAID-Z. I installed a custom BIOS that removes the limitations on the optical SATA port and run a small single drive for the OS off that.

It's a dream to use and gives me 8TB of usable storage. I can easily hit saturation of the NIC and it's nice and small and quiet, fitting in the bottom corner of my bookshelf.
I really think video games are a sweet spot in the stress-relief category. Reading (I'm an avid reader) didn't cut it, watching movies or tv, running, weight lifting... none of them relax me like gaming. Well, maybe drinking, but that's a different story :)
This is a pretty bold move. Interesting that they felt that management might be the source of cynicism, indifference and politics (I think they might be right). Can't wait to see how this experiment turns out.

This! Why do we let these rich robber barrens get away with having the lowest tax rates since the 1950s when the middle class is clearly falling off a cliff? This is ridiculous people! Lets raise taxes on these guys back to what it used to be under Clinton when we were doing fine, it won't hurt them one ioata, then we can fix all the problems with schools, hospitals, social security and build infrastructure to get some money back into the economy so people have some disposable income so they can buy things and get a healthy economic system moving again. This isn't that complicated, we can just be apathetic and go back to being peasants ruled by a few elite or we can demand they pay their fair share!
Well, they could stop you if they really wanted; they could IMEI sniff. AT&T does it to detect "smartphones" so they can helpfully add 'mandatory services' to your plan without your consent - it'd be easy for T-Mobile to block Apple's IMEI ranges from registering on the network regardless of whether your SIM worked or not.

The FCC should have implemented some actual common carrier regulations/a Carterfone-equivalent for the mobile industry. Instead, they're so mired in regulatory capture we get nothing.
But really...how did they do it??? This kind of growth is astounding!!

On the other hand, could get hit by a bus tomorrow.
I do actually -- I have 2 boys, 4 and 18 months old. They go to bed around 8pm and my wife at 11pm or so. I'm self-employed and work from home, so I stay up for a few hours and game (or work some more depending on the week), and then sleep in until 7:30 or 8. It works out pretty well, not gonna lie.
One of the reasons why people think that Gen Y is self-entitled is because they are so inward-looking that they (in general) never bother to think of what it was like for those before. It's all about "I hurt now"

Example: "Last weekend my baby had a fever, and we contemplated taking him to the ER, and my first thought was - had to be - “Oh God, that could wipe out our bank account! Maybe he can just ride it out?”"

As opposed to previous generations who had much less access to healthcare in the first place?

The boomers are such a target for Gen Y wrath, yet there's little reflection on how growing up was different for the two. Boomers and before just buckled down and got on with it, because life is tough.

I was once having this discussion online with a Gen Yer, and I pointed out the medical advances, civil rights advances, relative lack of scarcity, so on and so forth. Not to mention growing up under the constant threat of the Cold War, which makes the War on Terrorism look like child's play. Despite all this, the entirety of her counterargument was 'some schools now require metal detectors'. She just couldn't grasp what it was like to grow up in previous generations - where instead of getting a false promise of a better life, you got no promise at all, and fewer entertainment options for distracting yourself. And as a woman, life would have been worse, with spousal and sexual abuse swept under the carpet as a matter of routine, and entirely legal reduced wages for the same work.

Are Gen Y better or worse off than previous generations? I certainly don't think they're worse off, it's just not 'perfect'. This article shows a lack of perception of the hardships boomers had and overcame, plus it quietly sifts in some whinging because his choice of career is dying... which is his choice of career, unrelated to Gen Y, and I noted that there was no acknowledgement of people in previous decades whose careers fell by the wayside (farriers? manufacturers? miners?). He certainly didn't mention that there are entire careers that now exist that didn't 20 years ago (pretty much all of the internet-related environment, for example).

The simple test is: would you rather live as an average person now or in 1960? If you're a young man in the US, remember that conscription is about to hit you, big time. (edit: and common jobs are mostly manual labour - there's very little in the way of 'designer' and the like)
That's a revolution-worthy problem. Add some hunger to that & you're getting close.

I thought this too, but I think the real issue is that they want to extend and add new features to ZFS and the original structure of the project isn't appropriate. The SPL interface isn't ideal either.

Anandtech has really stellar reviews, and this review is just one example. I'm sure the number of charts and plots loses the people with shorter attention spans, but the alternative really is a far more vague review. I remember The Verge's video review of the Moto X filled with the phrase "the ___ is awesome", making it borderline useless. Moreover, I actually feel like I am gaining a much deeper understanding of the hardware internals when reading Anandtech reviews. While other reviews would simply say "the processor makes for a very snappy experience", Anandtech explains the new 28nm architecture and thus exactly how much potential it has to be more efficient, the overhead required to deal with 32 vs 64 bit apps, etc. Unless someone can show me otherwise, my tech news reading experience over the last few years leads me to believe that Anantech is in its own class when it comes to consumer technology reviews.
Yup, you're definitely right. Video games are almost a short-cut to unwinding, but they're certainly not a silver bullet.
I'm 30.

I have a good job, for a telecom carrier, I make more money than I thought a could, enough to live in one bedroom apartment and save a little for a rainy day. That said, I have no stability (I'm a contractor who's project could vanish at any point in time), no retirement (my retirement plan right now is death), no insurance I can afford (would cost over 10% of my take home to get it).

I long for stability, permanence and benefits.

I know right now it sucks - but I know in a couple years the boomers will be exiting the workforce in droves, and there will be room for me in the permanent roles. I just have to bide my time, be patient, and wait, and it will all work out. I hope.

Seems like the rules for C web development are the same as for any other language: don't trust user input, and delegate the sanitization to vetted library functions. It's not like it's 1991 and you have to use plain arrays and strcmp; there are really good, safe libraries for these things.

That said, doing web development in a language with neither a REPL nor built-in unicode support sounds like a Bad Time.
