    I was really surprised by the huge number of negative replies in this thread. Actually I found it really depressing. Computers are tools. I don't see any difference between withholding a compo until some arbitrary age and withholding a pencil. You try to introduce them early so that your children have a chance to have a natural ability with the item rather than a forced education in later life.

    My own children however gravitated to the technological devices in the house without any input from my wife or myself. We felt that as long as you can make the item in question safe and can accept the loss of that item then it is appropriate that they investigate.

    To help them along I dug out an old touch screen. The joy on my, then, one year old's face when he realised that *he* could make the ducky appear and go "quack quack" by pressing the big green bush (on the screen) will stay with me for a long time.

    The sad fact is however that much of modern computing isn't fun. Perhaps this is the reason that so many writers here want to shield children from what they see as drudgery and frustration. If you can remember that a compo can still be used to empower and bring a sense of achievement, that it can be a wonderful creative tool and provide pretty much instant feedback then maybe you can understand exactly why it's not a problem if it's a part of a younger child's day. Interestingly the same ideas go a long way to help us to understand where we've gone wrong in Software Engineering. Without any sense of irony I can say that much of what we do would be improved if it were designed to keep a 2 year old happy. Conversely, all of the things that frustrate and delay us in our every day usage of computers are things that a 2 year old simply wouldn't stand for!

    I got 'I can press keys' for my two year old from http://www.icangames.com/ican/games/presskeys.html (I have no association with the author). The program prints up simple full screen animations in response to (almost) any key press. The result? It didn't take long for my kid to associate the M key with the mice - especially if you 'go nuts' every time there are mice all over the screen! I don't know how much intrinsic value this has but it is hard to see how it is harming him as other posts seem to suggest.

    > The prequels are dull, but not because they are backstory.

    Sometime after ROJ a mate told me about GL's vision for 3 prequels. My heart sank. Sci Fi is supposed to be about the future not the past. Years later the prequals did turn out to be shit. Sure, the over-use of cgi removed any soul from the actors performances but I think the OP does have a point. Prequels/backstory may have a place in other genres but *not* in Sci Fi - and certainly not when too many of the same characters are involved.

    SW was successful because it was a grand fantasy. It opened minds and stimulated both adreneline and the imagination. When you tell a story arse-backwards you'd better be Tarrantino with your script if you want the keep the movie interesting. Even if you are that good, Sci-Fi lives and dies on two things (neither of which are special effects):

    1) Interesting ideas per minute.

    2) A glimpse of just how fucking big *our* universe actually is, or could be.

    Prequels destroy both of these: You're contantly having to limit your new ideas to handle the fan's desire for complete consistency; and instead of expanding your universe with a second big bang, all you're doing is running head long into a big crunch: a singular well known end point.

    It is the entire concept of a being a prequel that made 'Enterprise' still-born and the same thing will fuck up the new Star Trek film (and therefore the entire franchise):

    "Oooh, I wonder if baby Spock and baby Kirk will ever get through this???"...

    "Oh yeah, of course they will, ...yawn.".


    The script is hamstrung at the outset so there's nothing left to do but fill the screen with special effects. Really, prequels equals dream-sequence in terms of boring and pissing your audience off. Just imagine for two seconds the new ideas all that CGI could have been used to build!!!

  9. Relevant on Is Assembly Programming Still Relevant, Today? · · Score: 1

    "How relevant or useful is it to learn Assembly programming language in the current era?"

    Pretty amazingly relevant actually.

    Since the point of Assembly is to have a pretty much one to one relationship with the machine code of the target processor and all languages have to produce (or in the case of an interpreted language string together at run time) machine executable code at some point all programmers are essentially writing in assembly already. Compilers, interpreters etc are an intermediate stage designed to save the programmer work.

    There are two points to remember when discussing these intermediate coding stages: firstly you don't get portability, high level coding, object orientation or other benefits at no *cost*. There is always a trade-off between program size, program speed and ease of code generation. The second point to remember is that a lot of us assume that the compiler will do a pretty much perfect job in the conversion to assembly without first having a look at the actual output of our favourite one.

    As a final note, remember that that which looks beautiful, elegant and simple in a high level language can look like a dog when it comes to the assembly output or in execution (think recursive functions).

    To understand these points and make the most appropriate language choice for a given project there is simply no substitute for an understanding of Assembly Language. It's like trying to say you can learn to program without bothing to 'look under the hood' at all that ''Boolean logic'' stuff!


    Btw. 'Learning Assembly' means writing some real projects with it - not just reading about it in the bathroom for a couple of dumps.

    I'm not sure I understand your reticence. Computers are not dangerous 'Krell' educating machines! They are vital part of a modern child's exposure to the world. By their very nature children are attracted to technology of all forms. The number that can fully operate the DVD player by age 2 is amazing and demonstrates an innate interest and attraction. This kinda thing should be encouraged!

    When I look back to my own youth I can see a whole heap of time spent in front of the telly. Part of this amounts to nothing more than the usual, and I believe pretty harmless, squandering of time that all kids do (ie it's a *good* thing that they're not forced to run around the maze with a head full of tasks at such an age). However my own viewing also left me with an amazing amount of knowledge about the world. Tv is always lambasted for it's brain rotting properties but I tend to think that it has produced the most 'tuned in' human population ever.

    The internet is going to be an amazing sink of time and energy for my own kid. He's going to spend unbelievable amounts of time and energy on there. I think that, in the end, his generation will be even more wired in than ours. I think that this will be a good thing.

    The idea that there is any distinction between the world 'in there' and the world outside is kinda bizarre to me. 'Go out and play' is all very well if you're trying to teach your kid that their body requires use to remain healthy, but is kinda missing the point if it assumes that the backyard is going to provide 'better' stimulation than the tv or computer. Of course there's fun and learning to be had outside but it's no better or worse.

    I guess this feeling that computers are brain rotting devices like tv stems from the current trend towards users as consumers rather than producers. I am convinced that this will quickly change as the older tv-fed generation simply dies off. Computers are a stunning tool for production, imagination and raw thought. Their fundamental position at the heart of modern communication places them at a world-changing level of importance.

    I've got a touch monitor lying around the place. My kid can play 'Dora the Explorer' or paint on it even though he hasn't got the required mouse skills. In the future I hope he will use computers to express himself creatively and learn more about the world than I could hope to. If all this makes him more successful at work then great but it's not necessarily my priority. All I want him to have is access to the technology and to end up with a relaxed and natural usage of it.

    Others have commented that their parents, by holding back the tech until the kids were are bursting point, ensured that they appreciated the gifts that much more. I don't know about this. While I find myself to be a soft touch with my own in regard to toys (this'll have to stop, sorry Bob!), computers are simply too important. I think we've past the point where they're a novelty or toy. Holding them back just seems to be taking the kids back in time 30 years for no very good reason. If they have value then the kid will find it.

    I guess I think this way because of my own experience. Home micros arrived when I was about 8 and I just, ..I can't express it. Let's just say we were soulmates! Lol. About 5 years later the ROM blew on my Sinclair Spectrum and my parents didn't get it fixed. I was left writing programs on reams of paper. ("Paper??
