Not necessarily true. One could put a coal power plant in the middle of a desert where it presumably doesn't affect the environment & population as much as it would have otherwise.

You use a previous version of Scala to compile the trunk version. It's turtles all the way down! Just kidding. The initial Scala compiler was written in Java. After that was working, they rewrote it in Scala using their initial Java compile

With an application using garbage collection it's quite easy to have hundreds of megabytes just sitting around, so I think it could be a good idea in some cases.

RMS is an idealist, not a pragmatist. He must believe this is the ideal solution. Or maybe he's had a change in opinion recently. I have to say, this is the only cogent, practical argument I've heard out of him over the last few years. I re

My eyesight isn't that great. My contacts don't completely fix my astigmatism. I can't tell the difference between the displays, just that the colors seem a bit brighter on one than the other. A retina display seems like a waste for me. I s

The standard machine learning approach for doing exactly what you describe is to use a conditional random field. I don't think wikipedia has a great page on it , but check out http://en.wikipedia.org/wiki/Conditional_random_field for a ju

Yelp has looked at using collaborative filtering to improve recommendation accuracy (this technology could handle the spaghetti case you mentioned), and it looks like someone (probably an intern) published a paper on it. http://cs229.stanf

I also scored 22/25. I also agree that I will not be able to replicate that score, except for maybe on the last test. I find it interesting that I generally got lower scores on questions I didn't even have to think about at all, because I d

I met Phil at Scaladays in 2011. He was such a nice guy. I remember having some ideas about how to improve the efficiency of hash array trie maps for certain cases and types of data and I remember how encouraging our conversation was. He'll

Systems actually come standard with 48 gigs :) As it turns out, that's really useful for the part of my job requiring data modeling. Somebody suggested LinkedIn is one large application, which is absolutely false. It's composed of many smal

I'm not sure whether I'm happy to see this or not. + I'm glad craigslist has improved their product, but I wish it weren't a straight clone of a feature from another site. - I wish they weren't so sleazy when dealing with Padmapper - I wish

Take a look at Rypple too, they're a social performance tool Salesforce bought with a lot of ideas that were neat. You might be able to go pretty far with badging and achievements here. I'd think trying to "replace" a report card might work

Also - what do your monetization plans look like? I don't think this is something to take lightly. You'll never be able to charge teachers much for the service. Maybe enough for a lifestyle business though, if that's what you're interested

There are a lot of metrics we look at. The most straightforward are engagement numbers, particularly the social variety (like, comment, reshare, etc), normalized by various measures like impressions or sessions. LinkedIn does a fair bit of

LinkedIn's mission is to connect the world's professionals to make them more productive and successful. In that light, there are a few things that I consider the goal to be: 1. Keep you informed of relevant news, articles, and changes in yo

That's obviously NOT ideal. I'm not sure myself but I know who to ask. Will try to let you know more soon.

So he's complaining that YC startups won't get the guidance they need from VCs, and hence won't be successful. But isn't that part of the model? That they now have access to a YC network that could give them guidance and insight? Possibly i

It's both possible and necessary. Think about it - even a centralized service like twitter or facebook will have many distributed & disparate services that need to work together to provide a feed. Hence, there probably already is some k

I think you're wrong for one simple reason: business logic. Business logic is complicated and rarely defined by a developer but by a product manager. Often you can understand what's being done in the code, but the WHY is necessary to unders

Not to be mean, but how was any of this hard? True, I work on server-side development and I'm not a neckbeard, but this is part of my day-to-day job and I think the approach is pretty straightforward. Step 1. Design a test performance data

Im going to assume this is sarcasm since Facebook is built entirely on sharded MySQL. Don't want anyone else to get confused in case it doesn't come through for them.

Your boss should be fighting to make you recognized. That's a big part of his job. If he isn't making that effort, and if he isn't helping you find opportunities to be noticed, then you should look for a new boss who will. If course, if you

In his first example, implementing a header file/interface is only CMD-I in IntellJ. Everything else is done automatically. I can understand why text editing is a big deal, but having an editor that actually understands your code is a power
