I agree. I think that github is such a good tool to interact with git repos that if they made a version that can work locally (the main difference is explicitly dealing with the index and the current tree) I'd use it to manage git projects

Actually, google translate is the best academic system there is. They never lost a single nist evaluation (for an example see http://www.itl.nist.gov/iad/mig//tests/mt/2005/doc/mt05eval_... ), as far as I know, and they consistently publi

It is surprisingly easy to forget about poverty if you live shielded from it. You see a lot of this in brazillian urban upper-middle class, specially in the south.

At least here in brazil, where punctuality is generally disregarded, classes start on time (at most 5min tolerance) and people arriving 45min late to a scheduled appointment shouldn't expect to find anything waiting for them. At the same ti

By voting patterns, what do you mean? Features like how many times the user has voted in this thread/hour/day? How many times the comment has been voted, the replies have been voted, and the story has been voted? I didn't try those; maybe t

They can do something HBGary-style and hack sony's servers to gather confidential information that would embarass the company and bring the stock price down. That would hit where it hurts, can be doable with some social engineering, and any

The problem is that word features are not really that good predictors of quality. I have done some research on this (unpublished), and I got a really good performance on predicting hacker news votes by just counting how many new words (not

How about penalizing submissions by how often the title keywords and domain have been posted in the last week or so? This should push a lot of repetitive content down, and encourage the discussion to continue on the older submission. Whenev

Except with sufficiently snarky/provocative comments trying to shame the commenter might look from the outside like something very similar to petty disagreement. I think some people here are learning that hugely self-confident, strongly opi

Also, the bird's eye view in bing maps always makes me go back to it, it's great to see what a neighborhood look like and how it would feel to actually follow a route. Google street view is just too zoomed in and too painful to navigate in

I think it came with the economic boom, but I'm at a loss at explaining how or why. Also, part of my perception can be because I moved from a less to a more "civilized" place in Brazil (from Salvador to São Paulo). I have anecdotal reports,

Except bribes undermine social fairness significantly. Notice that as the clerk presumably knows how much money he should give you for your tax returns there is a strong incentive for him to ask for a bribe that covers a significant share o

I'm in the same situation, but unhiding friends to recover sense is just not practical, with all the app-spam going around facebook these days. I might be the only one in here who can't stand viral-app-spam, but in my social circle there's

It's not about never quitting, though. It's about quitting when you close the last document, or something similar, and breaking the distinction between closing and quitting. Heavy-duty apps should quit in the background after you close what

Actually I've created custom styles by modifying existing ones, and it isn't nearly as hard as it seems. Indeed, most academic styles are not more than a few hundred lines of code.

The issue is that generic machine learning algorithms work ok enough as black boxes, but to squeeze top performance out of them you need to do feature engineering, architecture/model structure futzing, method selection, etc, and in practice

The fact that transit visas are something you need to apply for, pay fees, and risk being refused (and that going into a permanent record) makes no sense for me.

UML brings back good memories from OS classes. We had to patch ext3 to add some triviality, and I did it first in UML so I could more easily test and make sure it was working correctly. It felt a lot faster and easier to setup than virtualb
