That's not what the paper is about. They still provide Consensus (i.e., total ordering).

lepacheco | 9 years ago | on: Say No to Paxos Overhead: Replacing Consensus with Network Ordering

Yep, I also think it's kind of a misleading name. It's still Consensus but with stronger assumptions on the network (kind of, it depends on an external master for correctness, which could itself use something like classic Paxos). Simplifying it a bit, they use a single sequencer that every packet must go through to get "ordered". As the authors suggest, that could be implemented in a programmable switch. Given that abstraction, they can simplify the consensus protocol itself.

From what I understand, there are three stages:

- interpreted

- If run 'enough' times, the code is JIT compiled (fast compilation)

- If run 'enough' times again, it is JIT compiled with the most optimizing compiler (slow compilation)

He was being sarcastic =P From my experience with a galaxy s2, most of the software from Samsung is not that great (and can't be removed without installing something like cyanogen... quite annoying).

I agree. finding smart, expert people who are willing to talk to you is left as an exercise for the reader ;)

lepacheco | 13 years ago | on: Are You Doing Research?

Paper reading is one of the ways of learning what else is out there. You can substitute that with talking to other people. Which Feynman did a lot, judging from the stories in his books.

Actually, now that I'm thinking about it, it seems to actually be MUCH more efficient (if you have smart people to talk to): trying to find the good papers in the middle of the sea of publications/noise is a very time consuming task.

going on preferences->appearance and changing the theme from GTK to classic made it much better for me (will look just like previous version). Also, in classic mode, the UI fonts are integrated with the window manager so you can change them, make them smaller, etc...

I also have some anxiety problems and from time to time my sinusitis shows up. What do you mean you just had a chronic sinus infection (instead of anxiety/depression)? What kind of symptoms are you talking about? This might be relevant to me...

Hollywood must be paying handsomely

Curitiba here

lepacheco | 14 years ago | on: How to seem good at everything: Stop doing stupid shit

People do stupid shit because most of the time they don't know "what" is the stupid shit in whatever they are doing. It is hard and only looks easy on hindsight. This is the part were a mentor or good teacher can make a HUGE difference.

lepacheco | 14 years ago | on: Crazy, Heretical, and Awesome: The Way I Write Rails Apps

My thoughts exactly... and by shoving domain logic into a bunch of EntityFooServices you might end up with code that is more procedural than OO. But maybe it's just the example that was too simplistic.

Really? Less than 1k/month here in Brazil? Where do you live? Or do you mean per month?
