  3. I'd buy this on 100% Free Software Compatible PC Launches · · Score: 2

    As everyone's being so negative about this, I thought I'd throw in my 2c.

    I quite like this idea, in fact I may well buy one. I'd never heard of it before today.

    Reasons I'd buy it:

    1. Form factor is neat and a sensible design (I'm tired of my big old clunky PC box taking up a lot of space).

    2. I only use Linux, and the fact that someone's gone to the effort of ensuring everything will work for me is great. No hassle searching the net trying to work out which hardware to buy. I'm busy and this saves me time.

    3. The price point is good. Macs might offer you a better price/performance ratio - but I don't care. I want something that is sufficient at a low price. This is 190 euros cheaper than a Mac Mini, so that is 190 euros saved. I don't care if it could have been more powerful for just a bit more cash. I also know exactly what hardware is in it, and it's been chosen by people thinking about more than margins (unlike Apple, who anecdotally at least seem to be very good at choosing hardware that breaks frequently).

    4. I like the idea of the project and the fact that it gives money to the open source community.

    My main criticism is that the hard disk size is a little small.

  6. Re:Mainframe or Server? on IBM's Newest Mainframe Is All Linux · · Score: 1

    I used to work on IBM mainframes four years ago and even then we were having trouble finding people with the right skillsets. Unbelievably, the vast majority of development was done in assembly and we used to train a group of graduates every year to keep the department ticking over on the programming side.

    As you'd expect, the company ended up relying on a small group of people who knew the systems inside out, who had skills that were in short supply and we ended up contracting them on very high salaries whilst most of the code monkeys were paid poorly relative to a typical developer's salary.

    At the time, I did suggest modernising to a Linux platform and using a high-level language but the vested interest was too great. You could see the skills shortage coming though, and there was one (disastrous) attempt to rewrite a large part of the system in Java - the team just ran out of RAM and processing power.

    IBM's kit was incredible though. It was so reliable that when the company moved headquarters we had to call in consultants from IBM to make sure it was ok to shutdown. That is, *it had been so long since the mainframes had been rebooted - many years - that we had no idea if the programs in RAM were even stored on disk anywhere!*. Kudos to the IBM guys and our techies, they did get the system moved without a hitch.

    > Just to be pedantic for a second: Genetic Programming (GP) is a specific application of Genetic Algorithms (GA) where the solution space you are working with is executable programs (or algorithms). So GP is a subset of GA, the two are not interchangeable.

    If we're going to be pedantic, then GP is not necessarily a subset of GAs. It depends on how you define a GA: usually a GA is an algorithm that operates on binary strings, and GP is an algorithm that most often operates on expression trees. However, in truth the definition of both is so vague that trying to draw distinctions between them is meaningless. Often the GA crowd will claim GP is a specialised variant of a GA, and the GP people will claim they can simulate any GA with a tree, so GAs are a subset of GP.

    They both share much in common, originating in related research communities and major conferences such as GECCO, CEC, etc. incorporate work on both.

    > To answer your question, GA is not more popular because for most real-world problems it's difficult to come up with a good solution representation (one that lends itself well to "breeding"). Though they have been used successfully for a long time in several different niches.

    The truth is, GAs _are_ popular, but indeed for niche applications. Academic research on evolutionary algorithms is still quite intensive, but industrial applications usually lag behind and a lot of work isn't "headline grabbing". This work for instance, is quite a simple and effective application of an interactive GA, but it could have been implemented in the 1970s from an EC point of view (apologies to my friend, who works on one of these projects :-D).

    You find most applications in the area of operations research. Slashdotters short on cash might be interested to know that a lot of time and money has been spent investigating EC for financial investment strategies, and indeed these are applied and used to make money. Any such application is going to be kept quiet, though :).

    Incidentally, if you're interested in GAs check out Estimation of Distribution Algorithms, which are a very elegant idea indeed.

I think this might be the next step up for genetic programming, because the high-value children would be better performers across multiple groups, not just alone, and it would eventually develop into a system that creates highly specialized individual components, and might discover new truths inside the approach.

    Sounds like you're trying to design emergent behaviour amongst agents. A very well-established field, and a difficult thing to do. One approach is indeed to using evolutionary computation (Genetic Algorithms, Genetic Programming, Evolutionary Strategies etc.) to program the agents.

  15. My Koalas are Performing Well on Some Early Adopters Stung By Ubuntu's Karmic Koala · · Score: 1

    I've been using Karmic since release on my laptop and desktop. Both work wonderfully - all hardware works perfectly (compare this to Windows 7 on my laptop: no audio, no accelerated graphics and no wireless). Only gripe so far is that I had to download proprietary stuff for my desktop wireless card, but I have to do that for each release and at least this time it was a painless experience (but did require using a shell).

    The biggest thing of note is how much more responsive everything is. I don't know what changes have been made to the kernel, but the scheduling seems exactly right. The things I'm doing take precedence, as do those applications that need regularly CPU time, such as CD reading and audio.

    Talking of which, the audio is completely fixed from my pov. Previously, I've had problems with stuttering under load, which was been blamed on poor configuration of Pulse Audio, but this seems to be eliminated now. The new audio settings app works great for me too, nicely sorting out my two sound cards, giving them sensible defaults and removing the clutter.

    Boot time is much faster, as is shutting down. My laptop suspends correctly. All in all, I have no complaints. The O/S seems so polished now that I'm beginning to find myself criticising the applications more. It seems that Canonical are going to have to get involved at an individual application level if they are to take things further, as the desktop is looking great and prior to GNOME 3 I can't see how it can majorly improve.

    Kudos to the Canonical team, I actually found 9.04 a bit disappointing, but they have clearly responded to feedback on Pulse etc. and delivered something great.

  16. Re:Seriously! Pay really is the issue!!! on Study Says US Needs Fewer Science Students · · Score: 1

    This is a reply to the comments complaining about pay in academia. I'm familiar only with the UK system, so perhaps this doesn't apply to the US.

    Yes, academic jobs aren't paid as well as industry. Yes, you can survive on academic pay, and quite comfortably. Yes, stipends for PhDs in Computer Science are plentiful in the UK and more than sufficient to live comfortably on (assuming you're not supporting a family, though I know people who are doing PhDs and have kids).

    When I finish my PhD, I think I will be disappointed with my financial reward if I get an academic research position. The salary will likely be about 29 000 UKP and I'd expect a lot more in industry. Having done 7 years of full-time education to get there, it won't have been financially beneficial to do so, and I don't feel "valued" by society for the skills I have learnt and the dedication I have shown.

    Lots of talented people do go to industry, or more likely merchant banking, for the money.

    However, I don't think we lose much by these people making that choice. In academia, you have to be self-motivated, have a passion for learning and prioritise academic integrity, creativity, freedom and the ideals of aiding progress and contributing to society in a long-term and abstract way over making money. I'm not saying making money is inferior to research: but academia is not about money. I'm quite happy for people to go chasing large amounts of cash in stressful and (in my opinion) less fulfilling careers - they free up space for me in academia.

    Please, don't make excuses about not being able to live on academic salaries (at least in the UK). A professor might earn 60-80 000 UKP and that is plenty to bring up a family. Consulting can bring much more.

    Academic life has many benefits other than your wage - flexibility, increased holiday, freedom, prestige etc. They count for a huge amount.

    Working in academia can be a greatly rewarding experience, the money is sufficient, and this if reflected by the continuous stream of talented individuals applying for PhDs and research positions. If you want higher salaries, then please make that choice without complaining that academia should pay more to tempt you away from other options.
