  1. Re:What does AJAX have to do with Java? on Thank God Java EE Is Not Like Ajax · · Score: 3, Informative

    Reflection.

    The Java runtime can handle dynamic discovery and execution of procedures in any old Java class file, passing around Method objects and such. This falls short of first class functions and very short of closures, but that's how it's done.

  2. Re:Old News on Professor Sells Lectures Online · · Score: 1

    A (as far as I know) complete set of notes (sometimes going back many years in the archives) exists at http://inst.eecs.berkeley.edu/

    Web casts are made available based on what room the course is scheduled in. As you may expect, the general trend is that larger rooms (which are given to larger classes) have web casting equipment.

    But I have found lecture notes in general to be very detailed anyway and in some ways advantageous to audio in the ability to skip back and forth.

    The point of your statement seems to be perspicuously absent.

  4. Re:Memory leaks on 611 Defects, 71 Vulnerabilities Found In Firefox · · Score: 2, Interesting

    Except this isn't a memory leak, but is in fact intended behavior. A memory leak is a fairly specific and (and in this case) a non-applicable bit of terminology, unless there is more to that article and comments linked to that I'm not seeing. You could instead argue that the behavior is not a good one unless you point to a reference that shows that this memory usage is, in fact, caused by a leak.

    On one side of the fence are those who say ram is cheap and we shouldn't care, but when "big" becomes "too big" is a point that is of some subjective judgment. I for one never have swapping problems with my workload and have firefox open for days, so I'm not inclined to care.

  5. Re:misleading headline on Personal Firewalls Mostly Useless, Says Mail & Guardian · · Score: 2, Insightful

    Except that the Linksys (Broadcom based, really) NAT boxes consume less power and can perform all of the above in similar. Keep in mind that these devices have a 200mhz ARM processor and 16 MB of RAM, and so are better than many computers that at one time ran BSD, consume less power, and have smaller footprint.

    If you insist on having more storage to install programs, one can always use a network mount.

    In any case, there's nothing to sneer at about these little devices.

  6. The Sun Micro guys got it mostly right on What's Spreading "the AJAX Wildfire"? · · Score: 1

    What I find terrifying about this whole AJAX thing is that now modern web development is entirely hinged on the implementation of an interpreter for a language in different browsers. The Mochikit Javascript library says this best: "Mochikit Makes JavaScript suck less"

    What if I don't want to write in Javascript? What if I feel that, for whatever reason, that I'd rather write my browing control applications in some other language of my choosing? And wouldn't it be slightly easier to standardize on a bytecode format (eg, what Java may have supposed to been for the web) rather than the rules of a language in all its gory detail?

  7. Re:Getting Away with Murder on Would Vendor Liability for Bugs Kill OSS? · · Score: 1

    hmm. each? Each is a lot of cables. I imagine you'd need something smaller than an inch to stay below the 0.8kg limit.

    But you probably have seen more than this amount of change from oxidation alone. Some things are always going to be more vulnerable than others, of course. The problem is that computer programs are akin to huge clocks where any failure in any computation will eventually cause unpredictable results. You can guard yourself with error handing, but I surmise that until this becomes more automatic (we've already seen some of this, for example, array bounds checking) the state of things will remain more or less constant.

    "Computing is the only profession in which a single
    mind is obliged to span the distance from a bit to a
    few hundred megabytes, or nine orders of
    magnitude."

                    Steve McConnel, "Code Complete"

    To compare software to bridge building given this ballpark assumption, the Golden Gate Bridge would fail if 0.8047 kg of a 804,700,000 kg bridge was somehow altered or removed. There is certainly room for improvement in accuracy, but this gruff "just stop whining and get it right if you want some respect" attitude falls between foolhardy and moronic. The margin of error and complete complexity of a reasonably sized computer program is less forgiving and more complicated than any wrought construction that happens in our physical world. It is an intractable problem, even in the rigorous sense of computational complexity as well as the more handwavy sense to fully prove the correctness of non-trivially sized programs.

    And of course, "you do realize" that this notion of "the unit price must be above the cost of production" has been meaningless for Sony and Microsoft for some time? I know not if Nintendo makes money on its hardware. There is a term for this:

    This is probably true unless you want to play a little semantics game and call the revenue ultimitely derived from game sales as part of the "unit price," which would be an interpretation tenuously connected to reality by most standards.

  12. Re:It's the immigration, stupid on Is Silicon Valley Reproducible? · · Score: 1

    This is false.

    No I mean seriously. It just is. I am fairly certain of this because I get my mail there. There are a number of immigrants, but to say "most" would be most generously called a stretch. Perhaps it is different in semiconductors, but this is coming from someone who does software stuff.

  13. Re:Key elements of Silicon Valley on Is Silicon Valley Reproducible? · · Score: 1

    One would be hard pressed to argue that Berkeley does not _feed_ Silicon Valley though. Heavy recruiting is done out of Berkeley for Silicon Valley companies.

    I'm one example, for instance.

  14. Re:wrong, there's cultural element on Is Silicon Valley Reproducible? · · Score: 1

    This might be a forgone conclusion, but....did you RTFA?

    "Conversely, a town that gets praised for being "solid" or representing "traditional values" may be a fine place to live, but it's never going to succeed as a startup hub. The 2004 presidential election, though a disaster in other respects, conveniently supplied us with a county-by-county map of such places. [6]"

    Paul Graham consistently talks about attracting young, smart people. While he doesn't spell out "risk takers," I believe that this is somewhat of an implication considering he gives the anti-environment for such places: traditional, "levelheaded", "solid" regions are not what one wants.

    "It's the young nerds who start startups, so it's those specifically the city has to appeal to. The startup hubs in the US are all young-feeling towns. This doesn't mean they have to be new. Cambridge has the oldest town plan in America, but it feels young because it's full of students."

    So I think your point is addressed. Those who can afford to take risk are generally young, so by attracting a lot of young, smart people you have a better shot at making businesses. (Provided there are some gullible rich people, too)

    There are a couple of bundles of lecture notes (#41 and #42 at http://www-inst.eecs.berkeley.edu/~cs164/sp05/lect ures/index.html) about proof checking in programs. Simply put, solvers can't handle programs of normal size in industry. Proof CHECKING, on the other hand, is quite fast, but that means the programmer has to provide a proof, which the slides show can get quite tedious for even small examples.

    The scaling has made the questionable leveling system inherited from previous Elder Scrolls downright oppressive. Now it is quite common to try and suppress one's level gain by using "reverse builds" where skills that one does not intend to use are selected as major skills.

  19. Re:Useless on Automating Future Aircraft Carriers · · Score: 1

    That sounds like a big problem. If the target is as juicy as an aircraft carrier, I don't think any serious opposition force would have a problem fielding both missile types and launching until the target is destroyed.

    sudo -i is the root-like shell.

    sudo -s starts a root shell, maintaining most of your environment (this is the most commonly used, I'd think)

    Breaking two passwords? Are you insane? With sudo, at least your list of sudo-able users is generally only readable by root (afaik) and sudo attempts on non-sudo enabled users are logged, whereas with the usual root accou setup anyone who breaks any user account can take a look at the user groups, find the root group (if any), and on many systems be able to su from any compromised user account by default!

    I would say your argument is fairly tenuous in substance, at best.

    I'm inclined to agree with you; generally, given any subject, some people are going to want to censor it, no matter how small the group (anyone remember the "Operation Clambake" on Google fiasco?). However, to say that we should only be concentrating on the issues and not suffering any discourse on pinning down an offending assocation of promoting censorship is somewhere between correctness and naivity. In the best case you are right, but in the moderate case it seems to me that you are somewhat unrealistic. How do you propose to cause change without considering very real and powerful things such as parties?
