Kobojunkie:
Some compilers allow you compile Python to machine code.

Byte-code is different from machine code. The target of a byte-code is of course a virtual machine (VM) which simulates a real processor.

I have no doubt that compilers for Python exist though. Are they mainly JIT (Just-In-Time) like are used in Java?

webdezzi:
what language did i end up using when i write a wrapper for a particular C function, then call the python function, at least it's now a python method?

Can you describe the process of calling a C function in Python (indicating message transfers - functional calls - using arrows) from the the actual function call in Python to the processor invocation of instructions)?

By the way, I read online that Python compiles to byte-code similar to Java (Python users please confirm).

In case some people still don't get it, which is faster:

1. Speaking English directly to candylips.

2. Speaking French, and then having somebody interpret into English for him to understand?

Or maybe both can be just as fast?

Somebody who remembers the basics of programming please correct me, but I think scenario 2 is faster:

1. Program-->Interpreter-->Processor

2. Program-->Compiler-->Processor

Maybe my fundamentals are a bit rusty.

. . .or what is the genesis of this argument sef?

Nobody in his right senses will implement an iterative and computation intensive algorithm interpretively.

Personal edition of monotouch will cost me $399

I think it will be cheaper for me to learn objective-c and use the free xcode IDE that comes with my MAC

LOL!

I know I'm baiting by saying this, but do you really need to "reinvent the wheel"?

Good piece of info IG.

mavenbox:
Oh boy, this Logica guy proud no be small o!

LOL

Absolutely. Now go tell all you know. "Logica is a very proud guy".

Dude you are so lame and it's obvious. Half-baked PHP script-kiddie pounding his chest speaking amongst software programmers/developers.

What kind of script monkey will be trying to make a point with a shopping cart - something that has been coded and recoded in so many ways? Do a search of Google if you can.

Meanwhile, solve the BP algorithm problems. I really dare you. I know it's wicked knowing you only know how to connect a form to a database (and then pound your chest proclaiming yourself a guru).

BTW I solved the problems in Java and Rhino Javascript. I hope that motivates you to go learn the basics of programming. There is more to programming than forms on a web-page and database.

candylips:

It's obvious the guy did not correct the code (did not leave a space between the closing bracket and 'VALUES' keyword, which you fixed, but he apparently missed the correction). Besides, it's been how many months now? 9 months?

If you are still referring to the talk about shopping cart and all those other concepts that have long since become standard since the turn of the century, you must be some sort of dinosaur, and you must find it hard reading like your comrade webddezzi. I will not waste my time creating a shopping cart when there are thousands of free code I can use for that. We Java developers treasure the concept of reuse - APIs and frameworks.

I have given you a link to show-case what you can do, knowing that the problems are not the usual form-post-to-database that people like you are used to. Funny enough, most undergraduate programs in real software development would have delved into such problems but I doubt you know the first thing about path-finding problems/algorithms and such. If you do, feel free to solve the problems and post your solutions.

Must be a post for the April Fool of 2009. Why will anybody respond with any seriousness to this dead thread?

In any case, I MOSTLY ignore posts like these because I believe a programmer should be self-taught. Such trivial issues are stuff you should figure out yourself (either by tasking your brain or doing a search on the Net).

Need I say that the "ML" in HTML stands for "Mark-up Language"? Or what does all the PHP code eventually translate into by the time it arrives in the user's browser? Bragging to know what language? How many problems have you solved other than reinventing the wheel, till the wheel literally falls off, and repeating the mantra of 70% adoption? Please -> -> -> . . .

If you want to demonstrate the power of PHP and your skills, go here and solve the problems:

Afam:
About scalability of PHP my simple question is this - Why do we have over 70% of dynamic applications out there running on PHP?

. . .because those 70% don't do not need the kind of high performance required of most business and high-volume applications. They are trivial. Duh!

It's like arguing that the best way to code any web application is to use static HTML, since static HTML pages were predominant in the early years of the WWW.

Candylips:

Yeah. Most developers I know only use scripted/translated languages for prototyping and not for high-performance stuff. But some, out of laziness after the prototyping phase rather than move to compiled leave the code in the scripted form. And yes, I was pulling out my hair when I used QBasic back in the day for a prototype of a game I developed, where having the same variable misspelled in a reference (e.g 'someVariable' misspelled as 'someVar' will result in another variable called 'someVar' being created).

Oh yeah OfBiz can be very off-putting because of its complexity (tries to answer all questions). But APIs/frameworks handling something as generic as a shopping cart can be easily found in almost any language. No need to reinvent the wheel.

Seun:
You don't need a fast language for ecommerce websites. The database does most of the work.

Well, the example of Twitter mentioned though not an eCommerce website revealed quite a bit. At first glance it's not more than storage and retrieval of messages. Now they are talking about asynchronous messaging (queuing) et cetera due to the high volume. These are things developers of highly scalable applications put in mind from the ground up.

webdezzi:
some how,i have figured out that u just wanna sound tech savvy, well, u sure know why a barell will sound very loud.

my last post was on productivity, same with afam's, u talking about ppl no longer using shopping cart which is complete off topic, well it may be the drive to talk about ofBiz. go ahead.

You ARE a slowpoke, you copy? You are also probably suffering from dyslexia or one of it's variants judging from the part of your quote I put in bold. Even an idiot knows I didn't say that, so where does that leave you?

Without even trying to sound techie, as in even in my sleep, you couldn't comprehend things I play with. Run along boy.

LOL!

Shopping cart? Who still codes those these days? That's so '97. How many Java-based free open-source frameworks with shopping cart functionality are out there? Literally hundreds, but I'll mention 1 - OfBiz.

@logica

Thanks the book looks like a new book. Can't seem to find any reviews yet for it

He he, no reviews because not a whole lot of people have shifted to coding for the iPhone. Those who have been coding for the iPhone typically already have much knowledge of Xcode, Objective-C and Cocoa. So you are going to have to be a guinea-pig. You may be the first to put up a review of the book if you purchase it.

webdezzi:
if i dont  know, i'll ask. this includes asking google.

. . . then why the condescending reference to Google?

webdezzi:
I am not some kiddie who google up to fill threads like (well, u know how u do your thing). if I don't know i'll ask.

While I don't think you are worth arguing with, I'll side-step your rants and ask; who do you think is smarter? The kid that uses Google to find answers, or you that ask questions that you can find more accurate answers on Google but choose to get answers that may not be accurate (by asking here on Nairaland)?

@Candylips,

If the iPhone featuring a stripped down version of the OS X (iPhone OS) can become a gaming platform competing with the PSP (and even considered more powerful), I don't think the OS X could have faired any worse.

BTW, I received an advert on this book in my box:
The Professional Programmer's Deitel® Guide to iPhone App Development Using iPhone SDK 3.x, Xcode®, Objective-C® and Cocoa®

OK. Maybe they got a patent on mobile phones, but they didn't even invent it! I suppose they bought it somehow. Yeah it's called multi-touch (a feature they partly simulate on the Mac as well using the "pinch" mouse gesture).

Yeah, App Store was good. Now everybody and their mama are coming up with their own versions. But it seems the iPhone innovations has been piggy-backing off the work done by the haxxers (Dev Team and friends), after all what can qualify as the first iPhone application store came up as Installer. With Android, I don't get that part about infringing on the touch-screen technology by Apple. It shares the same kernel as iPhone OS (BSD), therefore if somehow those features are already in the kernel it's none of Apple's biz.

candylips:
@Logica

I know you are an IPhone guy. Do you know the best book on IPhone app development?  Am just about getting started learning Objective-C and can't seem to find any Objective C book with a decent review

I have been using Apple's online manuals and they are crap

No I don't have any books. I rely on what ever I can glean from the Internet. BTW, don't you think Apple are making similar mistakes they made with the Mac with the way they are handling the iPhone? As far as development goes, I find the Android platform even more interesting.

Beaf:
It was a low blow I never responded to.
You did it because you've got nothing to say about java (apart from spewing worn out religious trash), so you resort to personal insults.

candylips has solidly defended Java, but you don't even seem capable.

Don't take it personally, just make your own credible points about c#'s superiority over java.

It was no low blow, and with the above post you have taken C# fan-boyism to the zenith. The response you had to my demonstration of the advantage of a verbose use of the import directive is a case in point. You have no clear understanding of what you tout, and that is what fan-boyism is all about.

candylips:
Am sure this was ment to be a joke 

There's a reason I called him a fan-boy.

Kobojunkie:
There are so many examples but I chose to use the pseudocode below to explain myself

Since there are so many, surely you can do better than pseudo-code?

" It is merely to point out that verbosity has its benefits, and there is usually a rationale behind it."

". . . a moderately verbose approach"

Where in those quotes of mine above did I say "Verbose is ALWAYS acceptable" or "Verbose always lead to BETTER readability" (inverting your assertions)?

I demonstrated using an example the usefulness of verbosity in Java. You should demonstrate where verbosity is not useful, using examples.

Kobojunkie:
Is it possible you could not make sense of the code because your python skills may not be as good as your java skills?
I am as we speak working on converting Java code to C# for a Networking project I have been working on. I can definitely tell you it is not taking me thousands of hours to come up with one line codes to replace every other 10 lines of Java I have seen today alone, and I don’t have 20 years of experience in this.

All kinds of failed analogies in your post from comparing converting a terse Python code (Python known for its strength in string manipulation) to Java and from Java to C#. Isn't Java & C# similar enough?

Then you compare the verbosity of a PROGRAMMING LANGUAGE to English?

candylips:
, DON'T TRUST MICROSOFT because I have had my hands burnt before ( Visual basic 4 , 6) and will not want to experience it again.

Ha ha, I started coding Java using MS J++ back in 98 (I found it pretty convenient, and I am very lazy). Then I had to switch when I found my applets don't work on Solaris. They only worked on Windows. So yeah, I was right in the middle of the Microsoft/Sun debacle, and I knew what the issue was about first hand. I later found Visual Age, then WSAD (now RAD), and then Eclipse and I never looked back.

Beaf:
I see where youre going with this, in c# you cannot do something like;

import java.util.*;

This is not a matter of what Java can do and C# cannot do. It is merely to point out that verbosity has its benefits, and there is usually a rationale behind it.
