  6. Is this really an issue? on The Hidden Engineering Gender Gap · · Score: 3, Insightful

    Interesting article, but I remain unconvinced that any extra effort should be expended encouraging young women into engineering/science than young men. Granted, both fields have exhibited either overt or covert sexism over the years, no argument. However, if I look at my own generation (I graduated high school in 1989 and university in the mid 1990's) and the girls I went to school with, none of them were told that they couldn't or shouldn't pursue a career in the sciences or engineering disciplines. I believe that the current generation of girls will have just as many career choices as boys and that this will continue. There were at least as many girls as boys winning the prizes in maths, physics, chemistry etc, so it's not a matter of gender differences in aptitude. Girls can clearly do this stuff as well as boys.

    Yet, many of the girls chose to do a humanities subject at university. Why is that? Could it be that they are more interested in those subjects than mechanical engineering or have they been socially programmed to shy away from the hard sciences? The flip side is that there is a disproportionately high group of females now studying Law and Medicine. In fact, apparently in some Western countries (like Australia, my home), more women than men study these disciplines and there could be a time when they outnumber men in the profession itself. Once again is this a problem and that we should be encouraging more guys to take up law or med? I don't think so...

    One thing that was interesting to observe in my time as a HS and then undergrad student was that there were far more Asian girls doing engineering than westerners. In fact of the female population in my eng/sci courses, 95% of them were Malaysian/Sinagporean/Indonesian Chinese (I studied in Australia). Even now, I work in an engineering company and most of the female engineers are of Chinese or Indian origin (we have about 20% female engineer population). The exception are the Scandinavian countries, where there there appears to be a higher proportion of female engineers than in other Western countries. The female engineers I've worked with are no more or less competent than the guys, so once again it's not a matter of aptitude.

    I think like any job or vocation, to be any good at it, you have to want to do it and do the hard work associated with it. This applies equally to pursuing a qualification or teaching yourself. If you don't have the passion for it, then you aren't going to have the single minded and borderline anti-social drive to be the best at it you can possibly be. Guys seem to do this more in the technical disciplines, particularly in the after work or school hours. Maybe girls and woman don't have the same passion for it and that their interests lie elsewhere? Should we be coercising girls into be interested in stuff like this? Hell no, in my opinion. If they are interested, they'll gravitate towards it just like some boys do.

    At the end of the day, this all starts from early childhood. In modern times, how many rational parents are going to stop girls from playing with trucks or LEGO etc if that's what they like? I'm a parent of a girl and boy (both the same age) and it doesn't worry me in the slightest. If my daughter grows up and becomes an engineer or physicist I'll be just as happy as if she pursues a career in law. She's a smart kid and will most probably be good at either.

    Chris Anderson of Wired magazine describes this as the "Long Tail Effect", where the availability of search engines and easy means to get at obscure material, be it music, books or whatever, opens up previously unavailable markets. He's even written a book about it. It just baffles me why the RIAA and MPAA have pursued the policies they have in terms of very aggressive enforcement against end users, when the technologies these people use have actually led to independent and obscure artists getting more exposure! I am 100% in favour of the artists getting paid for their work, but perhaps it's time for the old media companies to address their business models and move with the times?

    If they want go after someone, go after the pirated media industry in Asia. I live in SE Asia and I can tell you that it's harder to get a legal copy of a DVD or CD than it is an illegal one. That's arse backwards. They could start by making iTunes and their competitors available here. That might make a difference.

    All of that is true, *but* if I wanted proper enterprise class file serving, I wouldn't be using software RAID.

    There's a great way to test everyone's theories about how much executives actually do: form your own company. That way, you never have to bitch about how much the CEO makes, because you'll be paying yourself. While there is an old boys network when it comes to the executive jobs to a certain degree, plenty of people have risen to positions of power without it. The tech companies are classic examples of this. It really depends on whether or not you have an entrepneurial/risk taking mind set or nor.

    I used to think managers did bugger all until I became one. That was an eye opening experience. A lot of those F500 executives earn every cent in my opinion. I wouldn't have most of their jobs for double what they get paid.

    Seymour Cray would be the person you would be thinking of. I also agree about a large number of small machines, versus a small number of large machines.

  15. Re:Serious Requst - Want to biuld SQL cluster on High-Performance Linux Clustering · · Score: 1

    It depends on which database you are using. With Oracle, you generally use RAC (Real Application Cluster), which is termed "shared everything". That is, the database storage and connects are shared between the compute nodes of the database. Message passing happens between the nodes to maintain consitency of the database, particularly in the event of one or more machines going down for maintenance or a hard crash. This used to be called Oracle Parallel Server (OPS) and necessitated the use of raw devices, rather than filesystems and was pretty ugly to manage. It worked bloody well though. However, you could lose all bar one of your nodes and have the database still completely available.

    DB2 and SQLSERVER use a "shared nothing" approach, where the database storage and computing power are partitioned among the various nodes, so each system stores a different part of the database (Oracle can also do this via the use of a master node and DB links). However, you could theoretically lose part of your database if one of the nodes goes down (somebody correct me if I'm wrong here). The benefit is very good scalability, however, as you distributed the load over many nodes.

    MySQL offers a clustering option that appears to rely on replication to maintain consistency and redundancy. They say that you can lose a node and keep going. How many transactions are lost between replication intervals is unknown to me.

    So the question is: what application are you running and what database are you going to run it on? You basic requirements above are eminently doable on a number of products, but it depends on your performance and failover needs. You need to consider also the admin complexity of any solution. If you have to monitor partitioning and replication logs and don't have good tools to manage it, you can spend a lot of time managing that! I personally prefer the shared disk and a small number of large machines to distribute load and provide fault tolerance at the same time. Added to that, I want the database to handle all of it and abstract it away from the O/S and hardware, so I don't have to worry about it. YMMV though....

  17. Yeah, not enterprise class like Apache isn't... on SSH Claims Draw Open Source Ire · · Score: 2, Insightful

    This is just stupid. There are open source products out there that are clearly good enough to be used in "enterprise" settings and OpenSSH is one of them (Apache, Perl, Linux being some others). I've looked at what commercial SSH vs OpenSSH offers and I honestly can't think of a reason to use the commercial product. I agree (for once) with Theo and ask if it's not "enterprise class", why would O/S vendors include it in their products (Sun, Redhat etc)? For the record, all of my Solaris systems run OpenSSH supplied by Blastwave and the Linux machines have it already. It's all about the right tool for the job and open vs commercial is a secondary consideration (IMHO) over utility. In this case, the open source offering is at least as good as the commercial product.

    What extra features do you need out of SSH anyway? I ask not to be a smart arse, but as a genuine inquiry.

They get dusty, scratches etc. This makes it harder to enjoy the sound, particularly if you are used to listening to CDs.

  19. Re:To me.. on Calculating the True Worth of Software · · Score: 3, Insightful

    When talking about stuff like this, you get into the world of cost-plus versus value based pricing. The cost-plus pricing, as you alluded to, is based on the question: "how much does it cost me to engineer this widget, plus the cost of supporting it over time?". You calculate that cost and add markup to it to calculate the price you will charge. In a competitve market place, you will be under pressure to lower prices to win business, which eats into your margin. So you are then left with either reducing your engineering costs or accepting lower margins. That is, unless you are cheaper than your competition and then you get to preserve your margins.

    The other way to do it is to work out how much value this widget creates for the customer. You ask yourself the question: "how much will this widget do one of: lower operational cost, increase productivity, enable new opportunities or reduce risk?". If the numbers are substantial, you charge a proportion of that value as your price (you better be able to demonstrate that, otherwise noone will buy it). In my experience, value based pricing is higher than cost-plus.

    Which way you go depends on how much of a commodity your product is. For stuff that anyone can make, you have little chance of using the value based model, given a high rate of competition. For highly specialised areas, the opportunity is greater. However, most widgets become commodities in the end. Engineering practices become more efficient and the market widens for all but the most specialised of products (thereby increasing the volume but often lowering the price). You also have other players moving into the market and spotting an inefficiency they can exploit by being more efficient etc (Dell are the classic example of this).

    The firm I work for wrestles with this choice daily. Our tools are very specialised and often create enormous value for the customer (last week, one tool saved the customer over USD 1M, but we charged a fraction of that and still made excellent money). At the same time, the market is competitve, preventing massive price hikes.

    In terms of your question: I don't think there is an ethical paradox here. You simply decide which of the models you can use and charge accordingly. Assuming you are not in a monopoly situation, the free market will tell you if you are right or wrong with the pricing. I do, however, think that in a monopoly situation, the potential for market distortion and underhand dealings by suppliers becomes almost a certainty.
