You're probably in a much better position to evaluate than I am! My guess is that more Octave-based classes would translate into more users and more code written for Octave down the line, but I'm not sure how to encourage more use of Octav

I've always been a bit sad about it, but everyone involved is probably a rational actor. Computer science professors probably view a couple hundred dollars per MATLAB network license as a tiny expense on a $1m+ grant (whereas statistics gra

This is a great description of R usage (import, clean, fit models), but I think a slightly erroneous explanation of R history. John Chambers created "S" at Bell Labs. S was a programming language designed for interactive statistical analys

ezl does not seem to have gone all the way down the rabbit hole with the oDesk tracking link. (I work at oDesk, but not on this, so I was really curious.) After about 3 HTTP redirects, the www.dpbolvw.net link seems to turn into some sort

Actually, I thought his comment was quite delicate. I used to think that DB comparisons were bad because of vested interests, like Oracle refusing to allow anyone to benchmark them. But I now think that Antirez's view is much closer to the

I think the most succinct response to this question I've found comes from the Starcraft II casting archon, "Tastosis" during one of those filler periods where nothing is happening in the game: Tasteless: I'm a philosophy major, man. Arto

Is there a way to fix the recursion depth problem with this solution? To me, the memoized version is more clear and should be just as efficient as the iterative version. However, this version of fib_mem dies before fib_mem(1000)! Apparentl

This tutorial was a few months ago, though it was quite good. The slides are here if anyone is curious: http://www.slideshare.net/ipeirotis/managing-crowdsourced-hu...

I know a lot of Daphne's former and current students and she seems to be a great advisor who genuinely cares about producing both excellent research and top quality research talent. Further, in the department, I think she is one of the peop

Is this a CVPR reference, or just an amazingly accurate comment?

by pbh 15y ago
Yes, I think computer vision is a common term for the area (at least, among academics and researchers), and CV is a common abbreviation. Examples include Intel's OpenCV and the CVPR conference. (I actually thought that it was weird that the

I agree with your point, but with an important caveat. You are right that application developers should not be ignorant of databases, and DBAs should not be ignorant of what application developers are doing. All too often, this is the case

Unknown. However, the three classes are intended to match up with Database Systems: The Complete Book (which, in the interests of full disclosure, is written partly by my former advisor). If you want to learn the material from the second c

To answer a few of the database questions that keep popping up in this thread: 1. Is it worth understanding relational algebra? Yes. Definitely. It's not that hard, there's more or less a one-to-one mapping of relational algebra to SQL.

Sure, of course, premature optimization is the root of all evil and all that. I presume you're reacting to a bad experience in the past you had with some young developer not understanding database indexes or memoizing everything unnecessar

I'm not an expert, but this is what I've cobbled together as a fellow Ruby/Rails startup person. Fault Tolerance : Just use Heroku. We've seen maybe an hour of downtime in a few months? Speed (and fault tolerance): Cache everything yo

Nobody seems to have picked up on the "external" spam filter part of the response. My guess is that Y! uses some somewhat dodgy external providers of spam/content filtering. Historically, external providers that block inappropriate sites h

This is really helpful. I will definitely check it out. Also, I'm really amused that apparently the creator of DataMapper is (a) selling me on using Sequel and (b) the testimonial on their front page. (Not that there's anything wrong with

SQLAlchemy (and its excellent documentation) is the reason I switched to using an ORM. (Now that I am in Ruby land though, I am a little sad that arel/ActiveRecord/DataMapper do not seem as on their game.)

What's most interesting to me about this article is that the management of GAE seems to actually be getting worse over time. GAE has always had two main disadvantages. First, there is vendor lock-in because you code specifically to the d

I went through this thought process. I really liked Python and auto-scaling, so GAE seemed really appealing. But the combination of lack of SQL and inflexibility of architecture led me to want to create the sort of combination architectur

Somewhat related, I found Arrington's talk at Startup School '08 to be pretty good for getting an idea of how he views the startup tech press. http://www.youtube.com/watch?v=HbUnatPfSgg

Sorry for the delay! We actually got a bunch of orders, so we're in the process of running brainstorms for all of them. Since the blog post said that most of the iterations were a few days, we originally opted not to have a follow-up email

This is definitely a direction we're considering going in, but we're not quite sure exactly what people want. Are there particular features we should provide, constraints on domains, or other things that we could brainstorm that you have in

I really like the idea of combining AdWords with domain search, though I'm not quite sure what the right implementation is. For example, suppose that there are two domains, "[uniquequery].com" and "[commonquery].com". Do you think people w

Will fix that! At the moment, there's only one option so we'll probably just switch over to having a button, but I haven't had a chance to convert it yet. (PayPal has a habit of blocking your forms if they detect any mismatches between you

The brainstorming and initial reaction points are two points I actually forgot to make in the blog post. Thanks! Regarding brainstorming, I've found that I tend to get locked into one line of thinking when brainstorming domains, and the wo

1) There seem to be two things that impact the number of rounds necessary, your description and how many names are taken in that area. With the same description, usually one or two rounds is sufficient to see how well you're going to do (s
