  1. Your knowledge of GC is 10 years out of date on Xcode Update Gives Objective-C Garbage Collection · · Score: 3, Insightful

    Modern GC is *faster* than hand-coded free calls in 90% of situations.

    "A major reason for this is that the garbage collector allows the runtime system to amortize allocation and deallocation operations in a potentially advantageous fashion." -- http://en.wikipedia.org/wiki/Garbage_collection_(c omputer_science)

    Let's see... 100 minus 26... carry the 9... that leaves 74% share left for Intel, right? I'm going to have to go with "No, doesn't look like lights out."

    Please, quit it with the retarded questions at the end of the article summaries.

  4. "not many companies allow ... 3rd party libraries" on Java Regular Expressions · · Score: 1

    Somebody hasn't worked for "many companies." _Every_ company I've worked for allowed 3rd party libraries. (Sure, there are processes to make sure you don't do something stupid like ship a GPL library with a closed-source product, but that's just common sense.)

  6. BSD does NOT "have this advertising clause" on Google Announces Open Source Repository · · Score: 2, Informative

    This changed over seven years ago. To be unambiguous, Google (and others) refer to the updated license as the "new BSD license."

  8. Edge magazine on Gaming Mags Worth Their Ink · · Score: 1

    http://www.edge-online.co.uk/

    I'm addicted. It's a gaming magazine that doesn't make me feel stupider for having read it... unlike the trying-too-hard-to-be-cool US mags (*cough* EGM *cough*). Even the binding feels high-quality, like a soft-bound coffee table book.

    Too bad a subscription mailed to the USA costs *more* than the newstand price. ($130 for 13 issues at current exchange rates vs $8 an issue on the stand.)

  9. Setting the bar too high? on Tepid Results from Google's New Product Process · · Score: 5, Insightful

      Case in point: Google Maps, which trails only MapQuest in mapping-site traffic thanks to such innovations as aerial views and "click-and-drag" maps to make navigation easier. The product has become so popular that other outfits build new businesses or services around it, creating "mash-ups" that show things like real-estate listings or crime statistics on top of Google's maps. And four-year-old Google News offers top stories in 40 different countries and languages. That has spurred a jump of over 600% in international usage in the past year, making it the second-most-trafficked news aggregation site.


    A strong #2 doesn't sound like miserable failure to me.

    Does he really mean, "All the mainline FF games?" Or did he leave off the word "odd?"

    (Honestly curious; I've just played FFVII, which was ATB, and FFX, which was not, as I understand the term. So odd-numbered would fit my two data points.)

  12. Article author not very clued on Second Life Looks At Scaling Problems · · Score: 2, Insightful

    [uses] an unusual configuration that dedicates each server to a sliver of virtual real estate


    Er, no, that's not really very unusual at all, for MMOs, and dates way, way back. (Well, as much as anything in MMOs goes "way back...")

    It has a number of advantages and disadvantages over other architectures; it's generally thought to be more complex in terms of synchronization w/ "neighboring" servers, for instance, but this isn't something that would make someone who knows what he's doing go "WTF?" It certainly doesn't have inherent scaling problems.


    (x86 is the processor architecture used by most AMD and Intel chips)


    I think this is representative of the author's tech clue.

    "Learn some history"

    "I have a feeling that this same upper management is going to severely harm what was once a pretty sweet console."

    How could it once have been a pretty sweet console? It's still months away from release!

    Seriously, it's easy to sound "pretty sweet" when your product is still vapor. Making the tradeoffs needed as you get close to actually launching is the hard part.

  17. From someone who has taught intro CS courses on Should Students Be Taught With or Without an IDE? · · Score: 0, Flamebait
    Short answer: Go with the IDE.

    Long answer: the goal of an intro course can be one (or both) of two things:

    1. provide "enough to get by" instruction in an area
    2. excite students about the area enough that they take more in-depth courses

    Neither one of these goals is served by teaching the details of what goes on under the hood in an IDE. That can come later, for students in category 2.

  18. Great way to kill any interest in your course on Should Students Be Taught With or Without an IDE? · · Score: 4, Insightful
    Remember, submitter is planning to teach _intro_ courses to Java and Python.

    One of the most important things when you are starting out (and, actually, when you are experienced as well, but that's less obvious) is to get feedback on what you are doing wrong as quickly as possible. Don't throw this away lightly.

    It's quite easy for students to work very long and hard doing something _completely and utterly wrong._ This does _not_ make them better programmers than if they got immediate feedback on what was wrong; it just frustrates them.

    (I spent over a year teaching 100-300 level CS classes, and we actually started with paper-based flowcharting in one intro class, so I'm not speaking hypothetically here.)

  19. scaling rails on What's the Secret Sauce in Ruby on Rails? · · Score: 0, Flamebait

    "This means it already overcame the greatest hurdle of any web-development framework from day one"

    You give Rails far too much credit.

    First, among popular development environments, anecdotal evidence strongly suggests that Rails is _hardest_ to scale in the sense of "serving lots of pages really fast," mostly due to Ruby itself being pretty damn slow. I'm not a J2EE snob trolling here: it really is. For small sites this doesn't matter because your glue language is much less of a factor than hitting your database, but as you start caching appropriately and so forth Ruby really does become a liability.

    Now, Rails does make it easy to scale in the sense of "if I throw more hardware at the problem, throughput improves." But this is not a difficult problem. Arguing that "[m]ost Scheme/Lisp frameworks, for instance, still haven't achieved [that] level of scalabilty" is silly and probably false, but I'm not enough of a Lisp weenie to know. I _do_ know that Python, PHP, Java, TCL, .NET, hell, even Objective-C frameworks manage it. It's a solved problem; bragging about it just makes you look clueless.
