RUA people can graduate into RIA people if they first learn to dispense with the notion that RUAs _matter_. they don't. really. nobody is interested in how many RUAs you have written when they are looking for people to write RIAs. and I _mean_ nobody. RIA people need to show their ability to deal with complexity by reducing problems by solving the really big problems. RUA people show their ability to create complexity by profilerating tiny solutions. if making something you yourself can use takes 1 unit of time, making something somebody else can use takes 3 units of time, and making a system that somebody else can use to to build something that starts the whole scale all over again, takes 9 units of time. most people are extremely unprepared to build such systems, yet this is what it takes to grow an RIA programmer from an RUA programmer. that's why we need RIAs so people who think they are worth something in this here overheated industry can write RUAs on top of RIAs and make their employers happy -- they should not _ever_ believe that because they are using an RIA to write RUAs, they are somehow equipped to write RIAs. | To really meet their needs, it has to fit not only the better paradigms | but also the ones they already use, even if it doesn't fit them as well | as C++ does. for some reason, everybody realizes that civil engineering is different from building a toy city in a sandbox. you can't become a civil engineer by presenting however many pictures of beautiful sandbox cities. it takes much more than that, different skills, realizing different needs, different attitudes, different time lines, different economies. for one thing, you can't tear up a real city like you can destroy your sandbox city and you can't just start over if you realize that you failed. this is the really big difference between RUAs and RIAs. an RUA can be torn down and replaced on short notice. that's what makes it an RUA. an RIA can't be torn down without jeopardizing really serious investments, such as the entire existence of a company. there is hope for RUA people who are bored of writing small things, but there is no hope at all for RUA people who still think "hello, world" is interesting in any way, shape, or form. RIA people think differently, too -- most of them enjoy discussing large-scale philosophical issues, and are usually very hostile to the really petty issues that most people think are inordinately important in their own lives. RUa people are well suited to deal with their own lives in all its detail. RIA people deal with thousands and millions of lives in some particular respect. | The programmers know they will be working towards something better, but | they need a foundation to stand on while they work, and that means being | able to do what they do now, and advance from there one step at a time. this is almost entirely false. it is true in the sense that people need to make one step at a time to make any serious changes to their lives, but deciding to go from RUA to RIA is like going from playing doctor with the kid next door (while yourself a kid -- we're not talking about Visual Basic, here) to actually putting in the planning and all the effort to _become_ a doctor some fifteen years later, during which time you don't play doctor all that much, I can tell you. deciding to go from RUA to RIA is a _complete_ replacement of your whole mind-set towards what computers can and should do. (e.g., an RUA person may think it's OK for a computer to crash. an RIA person thinks of a dying machine the same way a doctor does about a patient, or a military leader about soldiers: it should not happen without conscious effort to avoid it to the best of one's ability.) | But fear of other tradeoffs, such as a 1000 to 1 ratio of the above test, | might be what keeps them from proceeding. no, what keeps them at bay is fear of insufficiency in becoming an RIA person. trust me on this -- I try every single day to find RIA material among the hundreds and thousands of RUA people I brush against on the Net and in real life. perhaps one in 200 people are suitable, and the best way you can spot them is they are _not_ exicited about trifling news and hyped-up products or stale ideas in new packaging. | Your post of your numbers was appreciated and surprising. I had no idea | ACL could start that fast on any machine. I'm a lot more interested in | the possibility of using it for a future project now than I was before. I'm sort of glad you appreciate it, but to me, the whole point was to get _rid_ of your false concerns, not help you validate them. I regret very much if I did the latter. start-up time is _completely_ irrelevant. as others have pointed out, if you need to perform a certain task often, you investigate scaling issues and find that optimizing for scale is a very different task from optimizing for individual execution. it's somewhat like optimizing for having fun in your sandbox compared to saving a city billions of dollars through excellence in civil engineering. #:Erik
