This is really sad news. I used to look at the Grooveshark interfaces with awe. You guys were always on top of your usability and design, right down to the 400 error pages.

I really love the goal you guys had when you started on this journey, and I admire that you were forging a new path. Before all of these music services came out, you were the only reliable option for listening to music the way I wanted to.

Josh, thank you for taking time to share your story with me when I was in college writing Startups Open Sourced. I admire your enthusiasm and persistence, and you seem like an awesome person to work with in any capacity.

I wish everyone at Grooveshark the best.
I don't know enough about how the patent system works. Wikipedia says Grooveshark is a service of Escape Media Group Inc. A few results show up in Google's patent search for Escape Media Group Inc.

That line interested me as well but for a different reason. Do schools in San Francisco not have an obligation to transport the children that are assigned to them?

Actually, I just looked it up the SFUSD page and it appears they do, and they offer school buses as I suspected. So the rationale for homeschooling by this person seems, well, irrational. Why would she need to hire six cars when buses would come get the kids?
I definitely think you're in the minority.

I don't remember the last time I bought an album or song, but I use streaming music services all the time. Same goes for anyone I know. Admittedly anecdotal but then again so is your assertion.

It might be. The significant return to individuals should come when they can participate in "ancillary services". These are classes of power contribution or absorption that meet short-term, urgent grid management needs.

For one example among many: if grid frequency drops below its nominal 60Hz, that indicates electricity demand exceeds supply, and the kilotons of spinning iron and copper in the generators that supply the grid are slowing down as they contribute rotational kinetic energy to meet demand. Grid management options for this type of demand/supply mismatch include calling for increased output from generators that aren't already at their max, engaging idle-output (but phase synchronized) spinning reserve generators, and buying power from contiguous grids.

Power sold under these circumstances can be priced at large multiples of base rates (like net metering rates) because of its high value in stabilizing the grid.

Smart grid infrastructure (communications, controllers, bidirectional inverters, etc) will allow grid managers (or localized intelligent algorithms) to draw on residential energy storage for ancillary services. These services should bring residential participants much higher returns than existing simple and not very lucrative net metering schedules. However, I imagine there will be significant legal combat before resident owners of distributed storage are allowed to recover market rates for their ancillary service contributions.
Serious question: Can anybody who's familiar with the energy storage field explain the nature and magnitude of the innovation here. Is this just a large lithium ion battery with some electronics added for charge/discharge control or is it a bigger deal than that? Perhaps the innovation is in packaging and productizing it for the various market segments?

It's no bug. I'm sitting here at the event, reading Hacker News because nothing is happening yet.
Does anyone have any experience with the pricing here and could elaborate a bit wether or not this is a good deal? This does seem enticing at first glance, but I am unfamiliar with any hidden costs there might be in going with a solar + backup system such as this.

There are two reliable ways to do it. First, you cross your arms over your chest and put your hands on the opposite shoulders. A brawny accomplice then stands behind you and picks you up by your elbows. Your spine is stretched by your own body weight and your accomplice's chest. That is truly satisfying, but I haven't had it done in many years.

Second method, you put your back against a hard, flat surface and push yourself into it. This one may only pop one or two at a time. And you might break your furniture.
The innovation is all in the price.

You are generalizing too much. Panic big 10 years ago? Coda came out in 2007, and it was pretty big for a while. So omnigroup is no longer a thing? They are alive and kicking. I agree that they both had faced problems with the Apple Sandboxing scheme, but I guess they'll overcome those issues (even by being out of the App Store).

What about Sketch, AgileBits, Alfred?

I know many long time devs who are still doing it and haven't sold their products to others to maintain... And I also happen know -lots- of new Mac/iOS devs.

Nothing to say about the 30%, it's just a pathetic argument, people have pointed it out already.

There is a reason to charge a $99 fee. There's also a reason to force a user to put a credit card to create an App Store Account, there's a reason to request a CC to create an Amazon account too. And $99 bucks is literally nothing, check MSDN and Visual Studio (https://www.visualstudio.com/en-us/products/how-to-buy-vs.as...).

About 'Apple Centric Skill-set' not being transferable to other platforms? Sorry, but... are you f'ing kidding me?

If you learn -any- framework, made by anyone at all, in-depth (not just copy pasting code here and there), you'll get skills that are transferable to other development environments. I've learned a ton of C/C++ and even some Assembly by doing iOS, I've also dealt with several scripting languages in the process.

If you're a real Engineer, and you really learn and understand a framework (Apple's or not) it should contribute to your growth.

Cheers.
You're not really disputing what I said: Mercurial is much, much slower than Git. Facebook forked it and managed to make it faster but they never released their fork so nobody can actually use it.

The bottom line is that a program written in C will always be orders of magnitude faster than a program written in Python. This is not news.

1. I believe the premise this question is based on is flawed. As other commenters have said, Functional vs. Imperative is not a binary state, but rather a sliding scale. Imperative is much closer to how the hardware works than Functional, so your style will need to be more "Imperative" if it needs to deal with lower level stuff.

2. Computer Science is very new and different styles move in and out of vogue as new tools and techniques are discovered. In this case "hype" is merely another term for "yesterday's cool approach". Just as "make everything an object" came and went, leaving its mark on every language, "make everything a function" will probably be less emphasized, but still an important approach that leaves its mark in most CS.
Any word on why not?
Yeah, looks like it keeps track of songs added to your collection in JSON format under the key "library<some big number>". Thanks for the heads-up.

As incontrovertibly illegal and probably unethical as this website was, I'm going to miss it. It was a great way to discover new music and I've become a fan of many artists that I found through it. There really is nothing like throwing a bunch of songs in the queue and saying "give me more music like this" using its radio service.
Does the same sort of thing, but is not nearly as good.
"Can anybody who's familiar with the energy storage field explain the nature and magnitude of the innovation here."

-Not me but clearly this is v1.0 and likely v3.0 is where you will have huge impacts. Similar to a Tesla costing 35k for their v3.0. The giga factory will probably play an even bigger part here as batteries should scale better than cars. So battery v3.0 should be >>> than electric car v3.0.
I've known some homeschooling families that were flat out poor. Plenty that were lower middle class-ish. Only a few that seemed wealthy.

I'd be surprised if there were many people who really wanted to homeschool but felt they could not because of finances. Some, I'm sure. *

Not wanting to homeschool in the first place is the bigger barrier.

* Homeschooling as a single parent, is, of course, tough. Some single parents do manage it.

On further reflection, I remember creating that account with no connections while investigating what was going on. I tried to log in from the email address that was receiving the emails but couldn't and assumed that the account had been cancelled for inactivity. I "reopened" the account (in reality creating a new one) on accident. So I retract any statements about them accidentally creating accounts, this was a while back and I had forgotten that portion.

But to be clear, that wohle scenario happened because LinkedIn started sending info to that (unaffiliated) email address unexpectedly, and I assumed if I was getting LinkedIn email there, that must be my account email...

It is just far easier to use a monospaced font than to implement a whole tabbing system in every editor you'd want to use. And the alignment needs can vary by language and application.

That's why it is so nice to work in a grid: you can align things however you like for any purpose. You don't have to rewrite someone else's parser or build a plugin to properly format an ad-hoc table in a comment.

31c was a pretty good idea
I switched to Rdio a few years ago, but before that I was a huge Grooveshark fan. Other commenters have mentioned this as well, but I think Grooveshark was waaaay ahead of their time with their HTML5 interface. I remember being absolutely floored by their big first redesign.

I interned at a quasi-competitor whose deal was to allow you to upload your own music (pre-Google Music) and I remember one of the founders constantly talking about how Grooveshark wouldn't last long with all the lawsuits. That was ~6 years ago, and honestly I'm astonished it took this long.

It's a shame to see it go. I don't have much faith in this happening, but hopefully some of the code makes it out of all this.

At the time it was a heavy music player with an annoying interface that only worked for mac users and was useless forever if you dropped it and the hard drive broke.

I discovered it a few minutes ago because I had just purchased a Premium Spotify license and opened Grooveshark to export my collections.

All my favorite songs, albums and bands were listed there, and only there. I used Grooveshark for a few years, and enjoyed it. Thank you for that.

But also fuck you.

Throwing away data like that is unforgivable for a service. Imagine Facebook disappearing with your list of friends, or Google Docs with your documents. Since ownership was transferred, I don't expect to see my data again. And this destroys all goodwill I had.

"The writing was on the wall!" Whose wall? Certainly not mine, not with Youtube and its obviously pirated songs still existing.

Thank you for the generous service, Grooveshark, but fuck you for destroying my music collection.

Powerwall – Tesla Motors
I think that the driver behind this is to create synergy across tesla and Solar City. Solar City gets requests for storage, and the financing to distribute it, and the giga-factory has a lot of surplus production.

Meanwhile, in lead acid battery land, a Trojan T-105 is ~$150 for a 6 volt, 225 amp hour battery, which you might comfortably cycle 0.9kWh each day for 5+ years. Use 12 of them to match the 10kWh Powerwall and it only costs $1800, replace them at the end of 5 years and you have about the same cost as the 10 year Powerwall.
Powerwall is several times smaller and lighter and presumably doesn't give off hydrogen gas when you charge it or burst and flood your room with sulphuric acid if you get to freezing temperatures with a discharged battery bank (done that), so there are certainly plusses.

It just isn't the silver bullet I was hoping for. I've been putting off replacing my batteries in a cabin while I wait for this, I suppose I'll nurse them through the Summer and make a decision in the Fall.
I trust that Tor browser will revert this for hidden services.
$3,000 for 7kwh and $3,500 for 10, both sound unbelievable to me. My first thought is there's a missing zero on the end.

Recently had a quote in Australia for >$AUD12,000 for a 5kwh battery set.

This is going to change everything to do with solar installations I think. Currently battery packs are a rarely taken up optional component.
#1 was pretty accurate actually...

>1. Admit it. You're out of the hardware game. Outsource your hardware production, or scrap it entirely

They didnt scrap it entirely, but they did ended up outsourcing production to Foxconn.

>While it may looks negatively in many western worlds, it seems to be working for Singapore.

The things that work in Singapore are as follows:

* Public housing (90% of the country lives in public housing projects and they are all high quality).

* Unapologetic Keynesian macroeconomic management -- when unemployment is edging higher, they might decide to build a new airport terminal. When inflation bumps a little high, they won't. No bullshit about debt ceilings.

* Mercantilist trade policy (similar to Germany, Taiwan, Japan, SK and Germany) - suppression of the value of their currency in order to give their exports a boost. Not used as much any more, but it built their industrial base.

* Intelligent city planning - development policy that is people centric rather than market centric.

Things that don't work:

* Authoritarianism - a culture of authoritarianism it's not just bad for people, it's bad for business. It's particularly bad for the software development process, because it hampers creativity and fosters slavish behavior (it's not just the government that is authoritarian).

* No minimum wage / pathetic levels of unemployment benefits / pension benefits - that's a feature if you own a company. It's a bug if you earn a wage (even a non-minimum wage). You don't see many beggars in Singapore. You do see 85 year old women collecting bottles for recycling and selling tissues.

* Mandatory 2 year military service - doing useless crap for two years won't help the country if Indonesia decides it wants to invade. Again, fosters slavish behavior (possibly a feature if you own the right kind of company).

* Restricted freedom of speech - that's a feature if you run a government, otherwise it's a bug. No, it doesn't help with racial harmony and it never did, despite the government's protestations. Neither does it have any impact on economic growth.
