Weight, Energy density. and cost are what's most important for general Electric car energy storage. So if this cost's more or weights significantly more it's next to useless for that. However, they might have some use as part of a more efficient regenerative breaking system.

PS: As to faster charging, issues are going to Limit that. A 99% efficient battery charging 100x as fast as Li-Ion is going to dump a lot of heat vary quickly. Duping heat is not really an issue for small battery's but scale this up into the 50+kwh range for an electric car or even just a cellphone battery and you will have significant issues.

You find a typo on the website. Instead of pull, switch the "i" to an "o", commit, push which takes 30 seconds you have:

1.) Open web browser
2.) go to your JIRA url
3.) enter your username/password
4.) enter your password again because you mis-typed it
5.) find the project page for that particular project and wait for it to load
6.) find the place where you add new tickets and wait for that to load
7.) type in a bunch of bullshit on a long form and submit that
8.) Hopefully you get to assign the bug to yourself. God forbid you have to have a PM do the actual assignment!
9.) pull, make the change, push
10.) go back into jira and open the ticket
11.) write a description of how you fixed the "bug"
12.) close the ticket

Ok, so that's the worst case, but the only real work you should /need/ to do is #9. The whole process of creating/assigning/closing the ticket probably only takes a minute or two, but it's probably unnecessary in most software systems and, over time, adds a ton of frustration where none is needed.
I think you're stretching, and I think we do know why Eich supported it. It was not for any legitimate or strategic reason.

There's no one universally best way, but there are lots of available ways that are good, and you need to try some out and find which is best for you (self-study from books; traditional classes offered via, e.g., local community colleges; MOOCs like EdX, Coursera, Udacity, etc.; non-MOOC online interactive-learning tutorials like those offered by CodeAcademy, etc.; etc.) -- and there is no reason to limit yourself to one of these approaches. Try more than one, and keep doing more than one if you find they work together for you.

Whatever basic approach(es) you use, the most important thing is to take whatever you are getting through it and find ways of applying to problems that interest you -- that is, the most important thing to learning to programming is to practice programming.

Personally, I think the mix of convenience, structure, and cost (free) of the MOOCs is hard to beat; the self-scheduled nature of Udacity makes it the easiest of the big 3 MOOC providers to jump into an intro programming class since you can do it whenever you want. So, I'd probably recommend that as the first thing to try if you want to start learning right now. But the introductory programming offerings from other MOOC providers (particularly EdX's MITx 6.00x class) are also worth exploring, as are other approaches.

True. But lutusp was shitting all over the submitter for dropping the almighty "design" word from the title and then claimed this is not an article about a battery but only about a design for one. That claim is wrong. It is more than a design... it is an actual battery. Maybe there is only one unit that exists. But that is still one more than a design. And if the tech proves sound but too labor intensive, your next thing to tackle is to make it easier to build. Isn't that how bleeding-edge innovation works?
Well... it's tricky. If you assume that current electric cars have the performance of that A123 battery from the graph, and then pick something in the middle of the spread of the colourful dots, you get a roughly 1 order decrease in energy density, and a 1 order increase in power density. So, taking the Model S as an example, you have a 300 mile range, and a charge time of like 45 minutes at a super charger.

So... now you end up with like a 30-60 mile range range, and can charge up fully in like 3-5 minutes. So we've brought charge times into the realm of filly up gas, but you're doing it waaay more often.

If this is a useful advancement or not depends completely on what type of infrastructure we want to envision. I would certainly love a world where this was possible/feasible, but it's certainly not a grand slam.
> asserting that Eich might have supported Prop 8 because he really does support gay marriage through some complicated nonsense.

This is a really weird, silly rationalization. Don't you think he would have said something to this effect when this blew up on Twitter? You think he's just sitting there on his hands going "Jeez, I wish there was something I could do to convince people that I'm not actually a horrible bigot, but instead have complex and inscrutable plans for a massive Supreme Court precedent in five years. Oh well!"

> by choosing not to work at the company (which doesn't take the same position) your actions put you at risk of committing the same sins that a hiring manager might make of choosing not to hire someone because of a difference of opinion.

You can't seriously be asserting that it's a "sin" for me to consider not working for someone who doesn't respect my or my peers' rights, let alone one on equal footing to employment discrimination. That's complete and utter bullshit. It's my right to vote with my feet, just as much as it would be a bigot's right to not work for me.

This is a classic case of removing purchase friction. There is a market that wants to hire cleaners. There are cleaners who want to be hired. The traditional way of hiring a cleaner or finding a cleaning job requires a lot of effort on both parties. myclean.com goes ahead and reduces that friction with a website. They allow both parties to meet without issue. No wonder they are doing well.

Now, can you do this too? Yes. Yes, you can. Go and research markets where there is a lot of interest in a service or product, but there is a lot of friction is purchase. Remove that friction and allow people to interact easily. No need to do much else, but market it directly (which is rather simple). You can even launch this without writing any code.

Though, Abe, the current Prime Minister of Japan a very conservative fellow, he surprised (at least) me the other day by announcing that he's interested in creating a culture of entrepreneurs and startups.

The most shocking quote in a recent piece in the WSJ[1] might be Abe, referring to Rakuten.com's Mikitani, saying "I ask Mr. Mikitani to not be afraid of being labeled a trouble maker and to speak his mind to his heart's content." You really can stir up some trouble in Japan by suggesting changes to the status quo (something foreigners do with regularity), so it's very interesting to see a guy like Abe say this. Maybe I misjudged the guy.

I think Japan needs to move away from the big electronics companies and focus on creating an environment more conducive to creating young interesting companies.

Don't you mean a charge in 24-30 seconds? Otherwise your example is just that of a 10x smaller A123 battery.
A few years ago I (briefly) worked for a defense contractor maintaining Jovial and assembly language code for an embedded system using 286 processors and running iRMX.

Work was in progress to create the next generation using more modern hardware and software, but the old system had to be kept up and enhanced until the new version was finished and deployed to all of the remote sites. The biggest impetus for change was the difficulty in finding replacement parts for such obsolete hardware.

Unfortunately, an emulator just wasn't an option. Being a real time system, the timing constraints were too strict. Think of the old DOS games that became insanely fast on more modern hardware, but with more significant consequences. For better or worse, I saw sections of code where there would be, say 16 no-op instructions, and a comment like "The following 16 no-ops give the bit-sync just enough time to finish adjusting before the real signal arrives". Tracking down all the timing dependencies and verifying they still worked on an emulator would have been a nightmare, and probably more difficult than creating a new system from scratch on modern hardware.

All of the dev tools were hosted on a VAX system. Fortunately, this one was able to use an emulator, and it actually ran significantly faster than the real system, and increased compile time dramatically. They still kept the real VAX around in the data center, but at some point the replacement parts and system maintenance costs became too expensive.
Thank you. Our Canadian developer is working on fixing now!

Great stuff, thanks! I just want to point out that ember-data wasn't used in any of the tutorials and that's a good thing—please keep it that way. Or at least keep ember-data out of the picture until it's more stable.

The official guides are focused on ember-data with little information on how to use an alternative approach until it's stable for production use. This was very confusing for me (I'm in the process of rewriting an application at work in ember).
You should understand that does not apply here. That quote doesn't extend to defending intolerance, because it is wholly incompatible with it.

This isn't surprising, but context is often lost with that quote. Think about it for a second, how can you advocate that you would defend one's freedom to limit one's freedom?
The problem I think is that the bitcoin address to send money to looks like its part of the table header description. So you naturally gloss over it and focus your attention on the table data.

I remember being completely blown away back in the 90s when I installed BeOS on a Pentium - on Windows 9X the machine struggled to play a single RealPlayer video, whereas under BeOS I could run 30 or 40 videos simultaneously with each window bouncing around automatically - and the sound had zero glitches(must have been some kind of demo?) Also you could put up to 6 live videos on the faces of a rotating cube, which was even more amazing at the time.
Excellent post and breakdown, especially, of the process and tools - thanks for sharing.

What was the bump / attribution of users to that single post?

When a company I was involved in years back was a Featured App in the App store that led to literally something like 10% of the user base, and the incredible PR / long term results from that made the company (out of eventually 10m+ downloads).

Sounds like the "luck" part of you getting featured was showing up in the community, building a great product? Or did you reach out / push on that?

Please stop using the term UUID when you mean 'random alphanumeric string'. Because UUIDs have a standardized format (it's not just a random string): http://en.wikipedia.org/wiki/Universally_unique_identifier
In my humble opinion, security through obscurity via UUIDS rather than sequential integers is not great advice. It merely masks the real problem.

Making Donations Social
What would happen if donations were made social?

I've been thinking about a crowdfunding music site based on this principal.

-Artists would post their music for free
-Anytime a User downloaded/streamed music it would get tracked on their profile
-Users would be able to donate money to an Artist and donations would be tracked on their profile
-Users would have the ability to enable/disable advertisements. The revenue from advertisements would count towards Artist donations
-Users would be awarded "badges" based on donations
-Users would have a direct line of communication with the Artist via some social community
-Venues would be able to see which Artists in their area were receiving the most donations and contract the Artists for shows.

There's a sense of "discovering" an artist that I think would be amplified because Users would have a record of who contributed to Artists before they became famous.
Users would have more of an impact on which direction the music they like moved in.

It's a really rough brain sketch.
Thoughts?
Hum, is Twilio more for integrating voice servies with an app? I'm looking for something stand-alone.
UUID v4 is, in fact, random and "alphanumeric" in the sense that it's hex.

That being said, I have a few other issues with their wording as well. They should just say "we have a custom HMAC-based authentication scheme for our REST API". Also, it took me about 3 days to realize HMAC over SSL/TLS is about as secure and easy as you can get for most any language -- If you can send HTTP requests, you can probably do HMAC. You can add further safety by making expiring private keys for HMAC and other things, although my use cases are based on long running (weeklong+) batch computations, and not end users. (i.e. initial distribution of an expiring private key for HMAC over SSL, reauthentication schemes, etc...

Founder of Mailbox app discussing "Disrupting Markets By Design"

In the same situation here. A couple of things that made a huge difference on the food and grocery front for us were:

- Ordering regular organic vegetable and meat boxes (we get a vegetable box once a week and meat once a fortnight). Find who does that in your area and give it a try. We use http://www.riverford.co.uk/ and I can't say enough good things about them.

- Online groceries. For the longest time, I thought people shopping for groceries online were weird. Now I understand. Give it a try - it will save you so much time and energy. The first shop is a bit of a pain but the subsequent ones are really quick as you can just go through what you bought previously and pick what you're running out of. In the UK, we tried ASDA (messed up every delivery - awful customer service), Tesco (can't remember why we don't use them anymore. Think they were neither really good nor really bad) and Ocado (absolutely wonderful in every respect. And, just as they say, not more expensive than ASDA or Tesco).
To this I say--hooray for pervasive video surveillance. The surveillance (sousveillance?) state is here.

Imagine the deterrent that continuous, complete video surveillance would have to all crimes in public (and private) spaces. Simply use cameras to track the suspect all the way to their current location, and arrest them there.
