  2. I think people forget what each is for on US Air Force Buys iPads To Replace Flight Bags · · Score: 2

    sure, the ipad is a great way to replace paper. but clearly someone's forgotten what the flight bags are for. there are a few beautiful things about paper -- it's always there, it has zero dependencies, laminated it can withstand more than the human using it, and absolutely nothing can go wrong with it. it just can't break.

    so since these things are consulted when the plane breaks, two engines die, and the power is out, it's nice to have the redundancy be a completely different technology.

    so when the ipad hangs, is there tech support mid-flight? remember, paper has zero tech support requirements.

  3. Re:the trick is... on Ask Slashdot: Making JavaScript Tolerable For a Dyed-in-the-Wool C/C++/Java Guy? · · Score: 1

    it's not about being-able-to it's about the entire concept based around it.

    in perl, for example, that one line would actually auto-vivify the entire structure. Think about how much code would be required in C to create that kind of structure, let alone test it for various truths.

  4. you developed a style for those other languages. and you based that style on the strengths of the language -- I hope.

    the only thing that you need to do is to see what javascript does that your other languages can't feasibly do at all. And here's the example:

    window.parent.self.document.body.frames['headerFrame'].contentWindow.parent.document.body.getElementById("eNavBar-26s-t").offsetParent.children[7].style.top = "35.4cm";

    it's all about the most efficient way to develop using the DOM. forget about processor efficiency, it's about developer speed. forget about the ability to create complex structures, they are already there. the DOM is as complicated as the above, and moreso. There is already an API to an application (the browser itself) and you've got huge structures tto play with, and they matter in real time.

    the above snippet navigates from virtually no where through window placement and size through child and parent windows and embedded browsers, both into and out of embedded browsers, to a specific element then to related elements then to an unrelated element, then moves it to a location that may or may not be relative to other locations.

    so in that above case, you're going through the presentation layer (the web page html), the network layer (tcp/ip), the window layer (the tab and chrome and buttons), and the content layer (your actual content between html tags). and you can set anything along any one of them, and it just changes, magically.

    it's data-centric programming. you aren't calling functions and issuing commands. you're just changing data structures, that's it. something else (the browser), is monitoring those changes and acting of its own free will.

    cool or not, it's wildly different than instructing a computer to do things. you're not. you're just manipulating one huge data structure -- and it's nested, and hyper linked, and looped.

    c and java aren't very good at playing with unbalanced crazy data structures. perl is (see auto-vivification), and javascript is.

    now, the fun stuff that you'll get to in javascript is the world of polymorphism. if you wanted to use javascript for non-web stuff, you'd go ape shit over the ways in which javascript can do really cool things with prototyping and inheritance. and the fact that it all becomes visual too is really fancy compared to the java or c equivalents. but most web programming doesn't use that sort of thing, so you won't be quite that happy most of the time.

    think about linked lists without have to handle them yourself, then think about hyperlinking in data structures the way the web hyperlinks urls. it's not about programming the way you're used to. it's not the same. they call it programming, it's not. it's not even scripting, because you're doing nothing more than changing an existing data structure. everything's a utility function that you write to change the existing data structure.

    it's not programming, and it's not scripting. it's scripted mark-up, which is exactly what it is. it's taking html markup, and describing the way it should change dynamically. it's dumb-fk stupid, and it's really basic simple, quite frankly, LOGO was more effortful to code, but because you have so much output and control over levels of interaction with living users, it's fun.

    but it's not interesting at the programming level. it's not about that.

    so how should you do it? have a browser window open at all times. change one line, hit refresh, see the change. it's not about the code. the code isn't cool. the output is cool. look at the output, not at the code. you should refresh about 100 times per hour of coding. you should make yourself small output consoles to watch variables and track output as you need it. you should be staring at the output, not at the code.

    look, you're missing the point. at 4k per month, you can hire ten students to drive your car around the block until you're done your work day.

    but again, I want you to pay 25 per hour, because it benefits me when you pay the city.

    why would you ever assume that 25/hour is 4000/month? haven't you ever compared renting to leasing to financing to owning?
    you're clearly not that stupid.

    and 500 per month isn't more expensive than most cars. that's 6k per year, given a typical 30k car, you're at 40k after taxes. typical family buys one every 5 years. that's 8k per year. that's more than parking.

    not to mention that the 8k per year is the car, not running the car. 2k gas, 2k insurrance, and 2k maintenance. so the car is really 6k more than its cost per year.

    you also have a garage or driveway dedicated to the car. that's property cost, and property tax, together mine amount to about 3k per year. maybe you clean your car, I get mine cleaned occccasionally, that's another 1k per year.

    I also go on long driving trips, costing another 2k in gas and 2k in maintenance each year.

    I'd say that a typical car owner spends about 20k per year on the car and its ilk. so parking isn't anything to be concerned about. especially since parking usually gets rolled into another task, like a meeting, or a birthday, or a dinner, or a show.

    anyone who thinks that they spend less than 20k on their car every year, either forgets about things like the garage, or doesn't actually use their car much.

    You won't understand how, because you've never tried.

    You don't know how to do things that matter. And that's fine. You don't know when your actions are a benefit to others, and that's also fine. You don't know when those same others will gladly do things for you, that too is fine. What's not fine is that you don't know when those things cost those others zero dollars and zero effort.

    That's not fine because you're not taking advantage of what someone else actually wants to do for you. That means that everyone loses out, because you just don't know.

    So go find out. Or, you could ask me, and I could tell you, and then you'd know. But then, you'd be listening to what I have to say.
