There are two main causes for "not large or reliable enough".

The reason for "not large enough" is calorimetry. When you hydrolyze water some reforms back into steam and escapes. So you subtract that energy as lost in your calculations of output - input. The error is in not correctly calculating how much energy is actually lost vs left in the experiment.

Good experiments don't allow any steam to be lost, they are perfectly insulated and keep everything inside the cell. Unfortunately it's extremely hard to do this accurately. (Or you can generate so much energy it's more than the input without subtracting the losses, but no one has ever been able to do that.)

The reason for not reliably, is that experiments look for signs of radiation. Palladium is sometimes sourced from refined nuclear waste. It's refined extremely well, it's perfectly safe. But it has just enough residual radiation to cause very strange data for the experimenters: One batch of palladium works great, the next batch doesn't work at all, and they can't figure out what's different.

I'm sad that people voted you down for saying that.

Yes, I work pretty close to 40 hours each week. Honestly, I tend to come in too early, and leave a little early from the schedule I told them I'd work. In the end, it probably is more like 41 hours.
Depending on what Apple's vision is for SmartTV functionality the A5 or A6 platform can last the life-time of 1080P HDTVs. It will be more like gaming consoles than phones/tablets/computers that are more open ended in their functionality. A SmartTV is a less versatile device. All you really need is the horse power to playback video & games at 1080P and the ability to do other interactive features. That won't change radically over the lifetime of the device. I guess the next big jump would be to 4K displays with an A14 (or whatever) platform to go with it. I could also see the add-on Apple TV continuing as a separate product for various reasons. (I don't see Apple making a projector so... I hope so at least)
Call to Action Button Verbs
Our e-commerce app lets users "Pre-Order" items in the store by filling in an email and clicking the "Pre-Order" button.

Check out http://madlov.com/qa

My co-founder and I are contemplating using other verbs such as:
"Get yours"
"Get one"
"Request one"
etc...

Does anyone have any suggestions for an enticing verb that we could use on our Action button?

In that case, why do Indians/Chinese "fit a pattern that appeals to them" and Blacks do not?

I focused on "like them" because that's a lower entropy theory than "fit a pattern" - it's a claim that VC's thought process is x -> cultural_distance(self, x).

"Fit a pattern" is basically just an assertion that VC's have a table of values in their mind, { "asian" : +1, "white" : 0, "black" : -1 } without explaining either where it came from or how we even know it exists. It's certainly very difficult to disprove, but only because it tells us very little.

Ask a black guy when the last time that happened.

Well, I'm a white guy, and the last time it happened to me was Tues. This happens to me fairly frequently when I'm in the US.

@protomyth I worked with the Dept. of Indian Affairs so I really don't need a lecture or directions on what to look up from you. The situation of Native Americans is heartbreaking. It was most certainly genocide and disgusting. Again, it is not about who had it worse it is just that there are distinct differences. The number of Native Americans in the valley is inherently going to be smaller because of the genocide that took place and the fact that unlike African slaves they didn't have anywhere to go to get more once they worked them to death. But native americans were not enslaved in the same way that Africans were--if that was the case there would be no reservations and no trail of tears.
A couple other things:

-XX:+UseCompressedOops converts many 64-bit references into 32-bit, trading a bit of CPU for a lot of memory

If you use a lot of threads, lower your stack size (-Xss) (no real method here, just drive some trucks over the bridge until it breaks, and that's your weight limit :P )

You don't want to swap! A good rule of thumb is to make your max heap (-Xmx) about 60% of total RAM if you only have 1 JVM running

Adaptive GC tuning algorithms can become unstable in long-running processes. I like to use -XX:GCTimeRatio for the throughput collector which effectively turns off the adaptive stuff. CMSInitiatingOccupancyFraction/UseCMSInitiatingOccupancyOnlydoes the same thing for the concurrent mark-sweep colletor. Keep the ice pick handy :P

But Spotify has very much upped the "scam" factor recently, by first cutting from 20 to 10 free hours per month, and now not even showing how many hours are remaining till you run out. Also, not until you find and read the long terms and conditions do you find out the first "6 months" (which already seem to be up for me) are a trial of premium, after that you get 10 hours a month free, but they won't tell you till you have 0 minutes left.
I'd also add that Airplay really eliminates the need to update your TV hardware.

The number of accounts compromised (or really, the number of times an account is compromised) has to be put in context. The context is the number of logins per unit time. So, I think they're both important.

And I don't think anyone is saying that any number of compromised accounts is a good thing. I question how much control Facebook has, though, given that many people will inevitably have passwords such as "abcd1234."
The ATT iPhone costs I think 80$ a month. If you get a Virgin Mobile phone with the same plan, it costs 35$ per month. And the Virgin Mobile plan is a little better.

I was also basing this off of the Sprint iPhone costing roughly the same as the ATT iPhone, and Virgin Mobile supposedly using the Sprint network.

Best example of UX for a financial news web app
Hello Guys,

I am new here so please be gentle. I am starting a financial news app i have so far based my prototype on bootcamp css but its looking messy.

i want a clean UX that follows web 2.0 companies such as dropbox,yelp,twitter but in a financial news portal sense.

Why Google Reader is the best social network created so far
I've been using Pandora since before they went public and just love the service. Prefer the old Flash version better than the current one but it is good none-the-less. I noticed Spotify on Facebook and became interested in trying it. Evidently I knew very little about Spotify because I thought it was a web app. Long story short never did try Spotify because I didn't want to download client on every machine that I work on. Pandora is still the best solution to the 1 playlist anywhere problem for me.

His response: lack of market validation
four people isn't validation. Even in stealth, you need to get a number of people
using your product. You need a revenue model, you need people using the service
to tell you what needs to be improved. Your idea may not be easily marketable and
clients are going to give feedback on what works better for them.

His question: why a start up would want to remain in stealth mode
Your response: I began to get slightly agitated

Regardless of your opinion of what he knows, he's the one with the money that you're trying to get. Telling the guy with the money that he doesn't know what he's doing isn't going to get him to write that check.

Refine your pitch, adjust your attitude, get some market validation and paying customers and approach other funds or bootstrap until someone notices you.

Let me offend some people.

When I see a white rapper I usually am already biased against them. Sorry, I have associated rap with black people. However the color test doesn't go past 10 seconds into listening to a record. Life isn't easier for a black rapper who sucks. Being shot 10 times won't help either.

So is it hard to be a white rapper? Maybe. But remember, Eminem is one of the greatest rapper to ever touch the mic, and Mac Miller, though a bit childish, is going to be great.
The JVM is very good if you are able to handle or avoid the GC pauses.

Unless you are running Azul's Zing JVM, some tuning is usually required for non-trivial systems. We have tuned our system to be very fast with low latency most of the time, and handle timeouts by using a load balancer in front of a few servers. The chance that all servers are having a GC pause at the same time can be made sufficiently small.
Channels suck right, so is this supposed to be good news?
I see what you're saying--if (and it seems likely) women really aren't at greater risk, we don't want to go around saying that they are. But, that's what I meant by "this is about emotions". For the purposes of this issue, it doesn't matter what the actual risk level is--the most relevant fact is that, for most women, it feels (emotionally) like they are constantly at risk. In the same way that a PR problem is still a problem, a perceived danger is still something that needs to be addressed. This is why perspective is important: because we don't perceive the danger, it's hard for us to empathize (or even sympathize), and you get comments like "just get over it".

Also, my focus on the terms "beaten, killed or raped" may have been more distracting than necessary, because we are talking about more than just physical oppression; there is also shaming, ostracism, objectification, and a host of other emotional attacks.

> What's up with the jaw thing? Women don't have especially fragile jaws. I guess you are saying that women have especially fragile emotions?

Other way around. It's a bit of a tortured metaphor, but it's not about women being weaker. Men are emotionally insulated by their privilege--it's an extra layer of resilience (the metal jaws) that we take for granted which makes it difficult for us to understand why people without it are having problems.

This discussion about what's the best approach to speeding up the web stack is getting old and browsers haven't gotten much faster since it began.

Ok so JS in its current form can barely render playback at 30 fps. What about video editing? The question is how much faster can JS get and there are no clear answers. V8 team at Google I/O 2011 said they're at about the limit, Dart VM would have been their next step but Dart the language/syntax got a poor reception.

I wouldn't discount shiny new improvements like Dart VM and NaCl yet. The problem is browsers don't need much new improvements to remain a dominant platform, because today's popular web apps don't require performance and we can make more popular apps that don't require performance. But if we had performance we could make apps that depended on it and they could be popular too.
I agree that it's not the approach for everyone. Worth making people aware of the capability though.
"People who hate their jobs often work 40 hours weeks, why be one of them?"

The quote smacks of truisim. Most people work roughly 40 hour weeks, so it sounds to me like saying "Most people who hate their jobs have jobs. Ergo, don't have a job".
no. Look at the binding energy curve. Even incremental increase of the size of nuclei for nuclei beyond iron (actually Ni-62, ie. still left of Cu which is supposed to be the result of fusion here) is generally energy consuming process.

I'd argue what you're saying and what he's saying are different arguments.

Your arguments almost all apply to poor people in general (and I believe them to be absolutely true). In fact I'd argue it's more true than people know. When hearing the legend of Microsoft rarely do people include the fact that his Mom was on the United Way Board with the CEO of IBM and it was she who pointed IBM in Microsoft's direction.

But that's different from the argument he's making. You're making the point that it's hard to get to the startup level he's arguing that once you get there you're at a disadvantage because the Valley has a subconscious racism in it. That I honestly don't believe.

He says...

"To be clear, I am not saying any VC says at a partner meeting, “you know I really like this company’s product but did you notice he’s a negro?” Never Happens"

The problem with that logic is I've been in meetings where the exact opposite is true. Where people have said "I'm not completely sold on the company but I'd really like to see more minorities in our investment portfolio". So in my experience I've seen the color of someone's skin actually help people a lot.

So while there's certainly some subconscious discrimination there's also some very conscious actions being taken to seek out minorities and I don't think anyone can say how frequently either of these phenomenons are happening.

I rarely see a VC or incubator read the entire statement or much less click through to a beta. They care about numbers. You could have the next Google or FB but if you can't show that people will (or are) using it then what's the point? For me, I had to do an alpha test w/75 users and I have hundreds in my private beta and have tons of articles and market research to show traction and I still get questions about "enough traction". Just think about it from the VC perspective: "How much am I going to get back on my return" That's ALL they care about. That's all they should care about. Plus, its not up to them to give you feedback. You need to get people on your product and ask them for feedback, iterate based on their feedback and then start shopping it around to people in your space and get their feedback. After that, you go to investors.

This is directed to tech co-founders. How much activity do you put into your business outside of coding? Do you actively recruit users? Do you take part in the pitch decks?

To me, a tech co-founder should be much more than a coder but I'd like to have some input on this.

Do you have any plans to support automatically backing up music between devices? Current solutions seem to solve either the "play anywhere" or "keep your music safe" problems, but not both.

Ideally, I'd like something with the following characteristics:

* Syncs music like Dropbox, except does it peer to peer between my own devices so I don't have to pay for space. My wife and I both buy music on both our computers and both our iPhones, and keeping a canonical repository of it for backup and safekeeping is a huge pain.

* Lets me choose which artists/albums to sync on to constrained space devices, for offline play. It should take me 2 seconds to say "I want Iron Maiden and Blind Guardian on my iPhone while I'm camping this weekend." Lets me do this from any of my devices.

* Lets me stream music without syncing it (like Audiogalaxy currently does).

* Lets me make tracks/playlists available to my friends for streaming (licensing issues around this one are tricky, but of Spotify can do it, it should be possible.)

I would LOVE something like this.
