  1. What do want to get out of it? on What's the Point of IT Certifications? · · Score: 1

    It boils down to why you want to get the certification. Is it a respected/valued certification in the industry? What do you expect from it?

    A while back I got the SCJP basically for the hell of it, so I didn't have great expectations riding on it. Much to my suprise, it translated into a small promotion, pay raise, and a nice little bonus. But that says more about my employer and director than anything, I think.

    A colleague of mine also attempted the SCJP exam and failed badly. He commented that "passing the test doesn't mean you're a good programmer", and while I agree, a good programmer would certainly be able to pass the test.

    The SCJP only really attempts to be able to validate the exam taker posseses the minimum baseline competencies in the language. I presume the same is true for many other of the technical certifications out there. If you want to take one for the hell of it, or if it's seen in the market as desireable, then take it. Just see it for what it is.

  3. Re:Write code like someone else will maintain it on Comments are More Important than Code · · Score: 1

    Amen to that.

    I typically am working on at least three different projects at any time, and once I realized that I was spending a fair bit of time re-reading the code and trying to remember what I was doing and where I left off last time, I got kinda religious about writing good comments that explained, for instance, what the method does, but also the assumptions and failure states, etc.

    Since then, I've found that the modest amount of time it takes to write good comments pays off with dividends next time I pick up the code again. I also think that verbalizing what you are doing in code forces you to think about it in a different way and not infrequently, the resultant code benefits.

  4. The design is the code on Comments are More Important than Code · · Score: 1

    I recently read the Jack Reeves article What is Software Design?. His thesis, really, is that the code is the design. I didn't really want to accept this at first, but I do see that there are some benefits to looking at it this way. In fact, I think that if one were to take this to heart while coding, the result will be better, more intelligible and maintainable code.

    Quality comments are one aspect of this (and I think that javadoc, for instance is a great tool). But just as the code isn't static, the comments need to also get updated, and it's fairly easy to refactor a method and forget to update/redo the comments.

    Another thing I don't usually see enough is coding to actually check whether input parameters are valid, or otherwise enforcing the "contract" between a class/method and it's caller. Simple, basic stuff, but I know what happens when fatigue set in and people are hurrying to meet deadlines.

  5. Re:It's about the symmetry on "Mozart Effect" Has A Molecular Basis · · Score: 2, Interesting

    It's too bad you posted AC, as this could have been an interesting discussion. Never-the-less...

    You quoted all but my last sentance, in which I state that the relationship between mathematics and music are that a) music and math use a symbolic notation, and b) you can describe anything using math. Note that I am making a distinction here between describing music mathematically and the way a composer actually conceives of music.

    You mention that since one finds symmetry in Mozarts phrasing, he must have conceived of his musical ideas in mathematical terms. This is nonesence. If that's the basis of asserting the relationship between music and math, why don't people commonly insist on the same link between math and the visual arts? Classicism was keen on symmetry in all the arts, not just music. This hardly means, however, that artists conceived of their subjects in mathematical terms.

    Music and mathematics were in many ways the same field for a while

    I assume you are refering to the ancient Greeks and their discovery of the ratios that describe the natural harmonic series.Yes we are aware of the theoretical contribution, but this hardly consitutes classical Greek musical practice. In fact, what's left of the fragments of Greek music hardly suggests that it was mathematically obsessed or conceived.

    ...many of us now do appreciate and compose with a tangle of aesthetic sensibilities, very much including mathematical elegance / precision.

    Well good for you and Stockhausen. The problem with the vast majority of that kind of music, is that it's very interesting theoretically, but it's not terribly musical and usually rather uninteresting to *listen* to. Don't get me wrong, this kind of stuff interests me a great deal, but I find that with most of these kinds of works, they are better appreciated in the abstract, rather than their implementation. An example of the contrary would be Ligeti's piano etudes -- there is certainly an abstract basis underpining the etudes, perhaps mathematically conceived in terms of the mechanism he wanted to compose out, but the etudes themselves are consumately musical, and once the *framework* was conceived, the rest was purely musical.

  6. It's about the symmetry on "Mozart Effect" Has A Molecular Basis · · Score: 3, Interesting
    Remember that he [Mozart] started writing in the Baroque period, where mathematical precision and principles were being explored in music. See Bach for instance.

    This statement is misinformed.

    While Mozart was born in the same year that Bach died, there was no stylistic relationship between them. It wasn't until much later in his life that Mozart even discovered the works of Bach. Even in his day, Bach was considered old fashioned, and was very much "out of style".

    While Bach looked back to the old contrapunctal methods of structuring a piece of music, Mozart (and his contemporaries) were involved with largely homophonic music written in the Sonata form. In terms of texture, music from the classical common practice (including Mozart) consists of a melodic subject, and an accompaniment, whereas textures in Bach's music relies heavily on imitative counterpoint.

    My thinking has always been that if the "Mozart effect" actually has any basis, it's in the structure of the melodic phrasing: antecedent consequent.

    In classical common practice, melodic phrasing usually followed the convention of an Antecedant phrase (often moving harmonically from the region of tonic to dominant), followed by a Consequent phrase (often harmonically moving from dominant to tonic). This creates a very strong sence of symmetry. To pick a tune probably everyone here is familiar with, think of the opening phrases (or any other for that matter) from Eine Kleine Nachtmusik.

    It is this powerful effect of aural symmetry that I suspect has the most profound effect on our minds. It also typifies classicism in every sence: reason, order, symmetry.

    BTW, I really find no basis for the all-too-common assertion of the link between mathematics and music. Composers (excepting people like Stockhausen perhaps) do not conceptualize music in mathematical terms. There is a relationship in that both music and mathematics have a symbolic notation, and that one can describe anything using mathematics, but that's about it.

  8. Email Fiefdoms on Microsoft Researching Anti-Spam Technique · · Score: 2, Insightful

    Having read the article, I was impressed by how clever their proposed solution was, though since I don't have a CS background, I don't understand how a mathematical computation can be essentially bottlenecked by memory latency -- I'd love it if someone could give an explanation of how that works.I'm guessing that some cryptographic hash needs to be held in memory, such that the nature of the data structure and physical access to it proves a bottleneck. This is probably way off.

    But having read the /. comments, it becomes clearer to me that this solution, and many other proposed solutions face problems insofar as they "break" the assumed contract under which email has worked for so many years. To me, this seems to boil down to a challenge / response system (allbeit one that increases the overhead of the transaction signifigantly). The problem with these systems is that for a time, email will be broken for certain people, or broken when trying to communicate with certain people depending on whether or not one has migrated to the proposed system. I'd worry that this would have the effect of segmenting email users into little fiefdoms determined by which email system they are using.

    I don't think a migration can happen unless there is some "benevolent dictator" who can force everyone to migrate to such-and-such a new email model and system, and frankly, I wouldn't want that forced on us.

    It seems that the challenge to any such spam-reduction system is that migration must be immediate and non-backwards-compatible, and universal, otherwise for a time email users will be segmented into little fiefdoms based on whether they've migrated, and solution to which they've migrated.

    The thing that kills me is that SCO's stock is still around $14 (up from $1 in March but falling the past week) - which means that most investors believe that SCO will be worth more in the future.

    No, I don't think that follows. First of all, you mean investors in SCOX, not all investors. Secondly, it seems much more likely to me that some / most are bying because of the limited downside (you're out what bought in at) and a potentially very large upside. Granted, I think most also realize that the likelihood of the upside being reached is very small; but with risk, reward. The small liklihood of realizing the large upside makes the limited downside attractive.

    This is a really overblown story. The figure they're quoting is only about 2% of insider shares, so it's not like this is a "pump and dump."

    Dunno whi I'm bothering to respond to this -- not like anyone will see this comment, but you need to realize that shares owned by corporate officers are what is called "restricted stock" (rule 144 of the NASD if I recall). You can't simply dump all the shares you have at one time. You must first file a form wtih the NASD or SEC indicating that you intend to sell x number of shares (how do you think Yahoo can report on the shares sold by corp. officers?). There are rules around how many shares you can sell at one time, usually relative to the total shares outstanding.

    The rule was put in place to discourage insider trading and prevent corporate officers from affecting the market for a given security. Imagine if an officer had a controlling interest of shares outstanding. He could just dump all his stock at once, and cause the market for that stock to tank.

    Also imagine if these rules weren't in place. McBride and friends could dump it all at once, fold up, and leave the rest of the investors high and dry.

    Given all this, it's not surprising the seemingly unimpressive figure of 2% of insider shares have only been sold --- yet. The rules were designed to slow this sort of thing down.

    Unclean hands is basically saying you don't deserve to get any relief because you have been bad yourself. Here is dictionary.com's definition:

    "a legal doctrine which is a defense to a complaint, which states that a party who is asking for a judgment cannot have the help of the court if he/she has done anything unethical in relation to the subject of the lawsuit. Thus, if a defendant can show the plaintiff had "unclean hands," the plaintiff's complaint will be dismissed or the plaintiff will be denied judgment. Unclean hands is a common "affirmative defense" pleaded by defendants and must be proved by the defendant. Example: Hank Hardnose sues Grace Goodenough for breach of contract for failure to pay the full amount for construction of an addition to her house. Goodenough proves that Hardnose had shown her faked estimates from subcontractors to justify his original bid to Goodenough."

    This is very true and is, in fact, how it actually works. You have local project managers and analysts who have domain knowledge of the specific industry (or niche), who then simple create a set of requirements which are shipped to India (or wherever else) for build.

    Not that this actually works very well all the time. For instance, I know of a project in my company (we're a financial services industry), which spent about a month trying to debug some strange inconsistancies in an application. It was finally determined that the cause of the defect was result of the Indian developers thinking a dividend was a fee that clients pay rather than money they receive.

    Arguably, you could just as well fault the analyst for failing to anticipate a lack of a basic contextual understanding on the part of the developers (e.g. what a dividend is), but you'd just end up with an even bigger pile of documentation that no one will probably read.

    This type of problem is actually comomnplace, but it's not a factor in the cost/benefit analysis that mangement performed when deciding to "offshore" developemnt work.

    Lastly, I gotta say that I think that the analysts are next in line to play "race to the bottom", even if as the example above suggests, it may not be worth it to business in the long run (costs associated with those type of defects).
