Completing, he also tries to make as clear as possible the importance of managing your memory usage (using GC or not), and how Javascript goes completely against this idea.
Good question. My educated guess is that the first problem would be security, after all you would be running a complete application simply by accessing the page. The second problem would be that as each one have a favorite language, in deciding what would be the "lingua franca" of the Web we would have a Digital World War
Debuggers are usefull. But if the developer does not know what and where to look inside the data provided by the debugger, it will not help anything. (And oh yes, the debugger does not replace the need for the developer actually know what they are doing)
Scripted languages have enormous advantage of being much easier to bugfix than native apps.
PFFFF Hahahahaha! Damn you, my desk is now a coffe mess!:-) Have you ever tried to debug something made in Javascript? With breakpoints, value inspection and etc? (If now there is a magical tool that could let me know because I need urgently)
The problem is not the bank fee itself. The problem is that you need to pay a lot in fees to make a transfer (And detail that is now done electronically, so the costs are insignificant to the bank). Think 100% in fees to a small transfer (or even more).
But thinking again, if both sides have Paypal accounts then becomes possible to send money, at least in the desired small amounts. Until banks do not sabotage it too.
You did not catch the subtlety of the problem. With this flat rate the bank make prohibitive for the average citizen to send money, while making it cheaper for the rich sending money. Who do you think makes banks act so instead of charging a fairer fee and proportional to the amount shipped?
I think you do not understand what I meant. I found the idea interesting in the sense of not having to pay a high rate for a bank, just because you are sending money abroad rather than somewhere within your country. Here, you need to pay more than $ 50 to send, say, $ 100 for a son who is doing study abroad. Roughly, here banks try to prevent you from sending money abroad or receiving, through extortionate rates.
Obs: It is interesting to mention that the "1%" here does not have any complications to send out millions, the difficulties and extorsive taxes are only for ordinary people.
Generic functions is a good thing when is well implemented and reasonable fast, two points where most "javascript libs" fails. As example, I experimented using the jQuery to do Ajax calls, but the way to do this is... atrocious. Works? Works, but what a cost?
And, when your code is only one in many, all competing for the CPU time, the execution time counts.
Sorry, Javascript IS slow. Libraries goes a bit more slow (you cannot load only part of then, and the functions are generic), JQuery is slow AND bad developed. Using a lib is not the problem, the problem is using a bad one and without a better reason than "I use then because is more easy".
If all applications decide that all system memory is for your personal use, the whole system collapses.
This does not happen on the desktop because most applications - yet - respect the fact that they need to share resources with other applications (and the desktop pc have a lot more resources than a mobile). But try putting in the same system several applications that do not respect that, and you quickly will have an unsustainable situation.
Not utterly, but is inefficient. At best, you need to load more code to do "X" with a framework than you can do with a specialized (and smaller) code. The gain may seem small, but in many cases makes all the difference
I'm not talking about price in dollars, I'm talking in terms of finite resource that must be shared by multiple applications beyond your application. If all applications decide that all system memory is for your personal use, the whole system collapses.
What he meant is the waste of memory that frameworks cause. And if you really knows what you are doing, is better to do your own specialized code than using a generic-framework one.
The very first mistake is try to make a complete GUI application in a shitty language like Javascript.
The second mistake, when you cannot avoid the first one, is to forget that computing resources are finite and therefore must be used as efficiently as possible. This include using bloated frameworks when you CAN make smaller code to do the same job, and rely on the "silver bullet" GC.
English is not my native language, and Google Translator is shit to translate portuguese-brazilian (my language) to english. As for the meaning, means more or less than here the "average guy" drinks like a sponge, do not have education, only speak about sports and treats women like garbage or object.
The "game" is rigged, sir. If you are not rich and/or good looking (cinema actor like), you already lost. How you will "play" the game, if you are not even allowed to take part in it?

Where is my mod points when... Well, you got it :-) Very well said.

It's funny seeing how people are rediscovering the importance of programming as a result of these phones
Very, very well said, sir.
Ajax is useful. The problem is that few know how to use it efficiently

without paying high international bank transfer fees
This is VERY interesting. In my country banks work hard to steal every penny from anyone who needs to send or receive money from abroad

Do not try to argue with fanatics.
Reread what I wrote ...

Really? My "Ajax" implementation is much more simple than jQuery, and works well.
Wrong. Memory on mobile is NOT cheap. Memory in a server is really not cheap (your application is only one in a many applications running, uh oh).

Fucking true.
