Last.fm is much better than grooveshark/spotify if you use this chrome extension: https://chrome.google.com/webstore/detail/bbncpldmanoknoahid...

I am listening to all the music through this plugin for last 1 year.




I was going to remark that this thing seems to appear monthly, and you guys just preempted me with illustration. So thank you, I'm glad I'm not the only one noticing repeat posting.


No that there is anything wrong with that. I just spent 20 minutes reading insightful comments from 8 months ago.


Just print this http://www.viemu.com/vi-vim-cheat-sheet.gif out and stick it to your side board.


By what way, do you think it is an imitation of Google Wave? Please elaborate.


My question too. I don't get the comparison to Wave.


At it's core, Wave was trying to attempt the same basic thing: bringing together all your communication into a single pipeline. Facebook is doing that exactly same thing. The difference here is that they are polishing the UI and the backend is incomplete, whereas Wave's backend was fairly complex and the UI (merely the client) was more a technology preview then the actual technology.

Aside: Google's Wave UI really was just a technology preview. It wasn't the product. People are confused by this (and rightly so), but it's not what made Wave awesome. The UI was merely what was added on top of the protocol so they had something they could show to the press.

Google failed Wave in that it made it out to be a different product. People confused Google Wave the UI with Google Wave the protocol.

Basically, Google should have made Wave apart of Gmail like Facebook is doing by making their messaging system apart of the default UI people are already used to.


I don't understand... you're saying Google Wave wasn't Google Wave? Google Wave is actually a product that brings communications together, but Google Wave wasn't Google Wave, Google Wave was just a technology preview?

How exactly did you find out about Google Wave and how it differs so much from Google Wave?


I'm going to assume your not just being purposely obtuse and actually curious.

Google Wave was two things: a protocol and a UI. The UI was merely a way to preview the protocol. The protocol was awesome, the UI not so much. People made the assumption that the UI was what Google was pushing, when the reality was, the UI was merely a way to demonstrate the protocol. Unfortunately, both the UI and the protocol shared the same name.

Hopefully you understand the difference now. =)


I understand the distinction between the protocol and the product, but neither was "bringing together all your communication into a single pipeline". That's your wishful thinking about where they could've taken the product, and something they never showed any intention of doing. All the protocol really does is offer a way to do concurrent realtime editing of documents.


No, it was far more than that. Real time document collaboration was a small part. Real time chatting was another big part. Comment tracking on blogs. Watch the demo again and you'll see. If you think it was just document editing you are mistaken.


"bringing together all your communication into a single pipeline"

Wasn't this by getting everyone to switch to Wave instead of email/GTalk? Facebook seems to have a more realistic approach here.


Yes and no. The beta was to move everyone to the Wave UI. They could have/should have built the Wave protocol into Gmail. In this case, Wave really was beta, and not a working beta like Gmail had been. I think that was the problem. People saw the Wave UI and assumed that was the end product.

Basically, Facebook is doing what Google should have done, baking the new stuff into the existing UI set.


Exactly!


Really painful for eyes too.


Yes they need to buy an office nearby to NYSE, to get fastest feeds(~ us).


Are there no hosting / cloud services for this sort of thing?


The network latency will kill you. You want to be in the same rack, not just the same colo, as the exchange's endpoints.


Are those slots in the same rack auctioned or something? How does having an office in a nearby building help?


Auctioned: I believe so.

I don't do HFT, but with what our company does, I've spoken to a few people who do. So take all of this with a pinch of salt, but as I understand it, your execution and autonomous trading systems live in the same rack as your exchange/dark-pool endpoints. Your slower strategies can be offsite, as is the Big Red Button to close down your positions. Still, faster's invariably going to be better, all else being equal...


Bash can also auto-complete remote paths, if appropriate keys are set.


HN readers are smart guys :)


Smart guys make typos too.
