Getting Started in Programming & Scripting

[Bibby]

Hi, I'm interested in getting started in the programming world. I've dabbled
in C, C++ and VB6. Which would be the best language to focus my attention to
regarding the following considerations:

Hireability
Portability
Flexibility

The likely candidates seem to be Java, VB.Net, C, C++, C#.

Also, what would be the best scripting language to get started in? Maybe
something that's a subset of an above language? Maybe scripting is a good
way to get started in general?

Thanks,

PA

Flexibility will lead to the other two. Abject pursuit of hireability will
not bring happiness. You can't buy love (but you can often rent it).

Every language in that list, and in your list of newsgroups, sucks.

You need to learn to learn languages. Nobody should say "I'm a VB
programmer", like they would "I'm a Mormon" or "I'm a Vegan". Linguistic
monogamy is a dead end.

(Also, Java is no relation to JavaScript.)

You need to research two general categories: Open Source, and TDD. Get with
GNU, Linux, and SourceForge, download their projects, and futz with them.
See if you can get one to compile (an herculean effort), then tweak it to
add features. You will confront some of the toughest problems in
programming - both logical problems within the code, and logistic problems
deploying that code.

Next, observe that many projects typically don't have unit tests. The most
popular implementation technique today is debugging, and it is slow,
fragile, and the source of many bugs and delays. If you instead learn
Test-Driven Development, you can trade long hours of debugging for short
minutes writing tests. Many TDD projects simply never use the debugger, and
never need to. This will put you in the forefront of modern programming, and
boost your hireability.

In order, personal preference:

Tcl/Tk (script language)
Perl (script language)
Visual Studio (VB, VC, J#)
Java

I started Tcl/Tk, because I needed an easy scripting language, that
would also do GUI interfaces. Then moved up to Perl, and integrated
that with the ktinit for Tcl/Tk, for more advanced, GUI scripts. Wrote
several applications, of various sizes and complexity in VB and .NET,
and now I'm working with Java, in concert with Oracle and MySql databases.

Your mileage of course may vary.

I'd recommend getting to grips with Java first. The design of the language
is very clean and you will not need to worry about pointer exceptions (no
pointers) or memory management (automatic garbage collection). Excellent
development environments such as Eclipse and NetBeans are also available for
Java.

C++, however, is very messy and has a much steeper learning curve owing to
its more complex facilities such as multiple inheritance; plus the hassle of
manual memory management and those pesky pointer exceptions.

Python and Ruby are two modern scripting languages, again with very clean
designs and fully object-oriented. If you want to do scripting for web
sites, PHP is still a popular and perfectly acceptable choice.

I'd like to second the suggestion for Ruby. It's really a fantastic
language, and the concepts map well to those in "grown-up" languages
like Java and C# well (at least superficially).

What sort of programming? You've said the equivalent of "I want to learn a
trade." Any idea what?
Consider these areas of the "programming world":

Animated Movies
Digital Signal Processing
Server Database Systems
Commercial Web Sites
Excel Macros
Artificial Intelligence
Anti-Spyware Programs
3D Internet Games
Server Management Tools
Device Drivers
Enterprise Resource Management
Streaming Video Players

Obviously there are many more. Which languages, platforms, and environments you
look into depends on what sort of programming you want to do.

I concur re C++ (ol C dog here) I use python and rebol for most web
programming. Rebol runs rings around python in terms of rebol code being
more productive than python code - but python has more libraries and a
larger user base that tends to thoroughly test the libraries and (from
my experience) scales better than rebol for large projects. Python is
very thoughtfully designed Object-wise. And there is a market for python
programmers, if you must seek employment.

But the main thing is to be adaptable. For instance, I use elisp to
customize my editor (emacs), use my editor to write rebol code that when
executed, produces python code, which when executed produces javascript
and mysql code.

My apologies to other "ol C dogs" - my unbiased opinion. Those header
files with object defs in them can be a real pain in the rear.

Java is a good choice for first language.
Really it comes down to the question of whether pointers or object
orientation is more confusing for the beginner. My own view is that even
experienced programmers often get into a mess trying to do object-oriented
design, and effecive use of objects cannot be taught in a few days.
Pointers, on the other hand, can be grasped in a few days, but only if the
beginner has the right mindset.

The other advantage of Java is that the GUI is standard. Whilst basically a
good thing, this does have the disadvantage from the learner's point of view
that it is easy to get too ambitious too soon.

So my recommendation would be C. However I'm posting from comp.lang.c

I wish it were that simple. A great deal of bad C has been written by
those who learnt Pascal as their first language. There is a lot to be
said for NOT protecting students from the consequences of lack of
understanding.

JavaScript seems to be an ideal beginner language. Virtually everyone
has a JS 'IDE' (notepad) and a JS interpreter (browser) installed.
Combined with HTML as your GUI you can learn to program 'Internet
applications' in very short time.

In California, at least, .NET is the way to go. I typically see at least
10-15 .NET jobs listed for each PHP job I see. They're pretty evenly split

As one who has nevery done any web programming, I can speak as only a hard core
unix programmer. Learning just language should NEVER be your goal.
A person I workd for for @ 17 years, told me "When you don't know where to
start, just start until you figure out where you need to start".

So if you interested in programming in one of the languages above, flip a coin?

Hey Guys, I really appreciate everyones input - it's really helping me out.
I haven't fully decided where to go yet but I'm leaning towards Javascript

journey and I can't wait for the day when I'll have some helpful advice for
another newbie.

Those 2 languages, JavaScript and VB, are the only 2 i would discourage a
newbie to delve into. Specially VB, which in my opinion is not a language
but a mind-corrupting scripting system.

Of course, the other way to look at it is that it'll make you appreciate

Concentrate on concepts of recurssion and closure and the like. Its a

The problem is not that it isn't a great language but that there are
pitiful good teachers of it. Most think procedurally and then try to
translate that into Lisp. The result is rather worse than Japanese
English (and I mean no insult to the Japanese, their English is a heck
of a sight better than my Japanese, but then the average Lisp
programmer's use of a procedural language is ...)

Yes. For example, FORTRAN 77 had no pointers. It also had no
structures, which often resulted in "parallel arrays" where what C
would call structure[i].member ended up being written as member(i),
member2(i), member3(i), etc. You could even sorta do "linked lists"
(where the array subscript substituted for a pointer). And you
could screw up with out-of-range subscripts almost as badly as with
pointers.

Is it possible to code anything without the concept of pointers?

Yes. Several programming languages have no concept of pointer that's
visible to the programmer. For example Lisp, Java and Perl have no
pointers. Perl has references which refer, somehow, to another perl
object - effectively equivalent to a pointer.

Lisp's don't have pointers per se. Each name in a lisp program and
almost everything else is "bound" to a piece of data of some type, and
can be freely rebound. Some of these data types can store sequences of
values. So, altogether there is no need for visible pointers.

(There are naturally tons of pointers in actual implementation, but
they're invisible to the programmer).
Like it or CPU's works with memory which means working with
pointers, any when things go wrong it will usually means a
pointer has gone astray.
Often yes, but not always, and not in languages where they can't go
astray. There remain plenty of things to go wrong without them though.
So like it or not I think a basic understanding of pointers
is essential when it comes to programming.

Yes, because it's how real machines work.

According to the Java Language Specification, it has objects and
references, and non-null references are pointers to objects:

"4.3.1 Objects
An object is a class instance or an array.

The reference values (often just references) are pointers to these
objects, and a special null reference, which refers to no object."

Is it possible to code anything without the concept of pointers?

Most certainly, in some languages. IIRC, Java has no pointers.

Well actually it does (it just calls them references)

I didn't know it called them anything other than "objects"...

It's remarkable, given the number of newsgroup to which this
discussion is inappropriately cross-posted, that Java isn't topical in
*any* of them.

It doesn't *just* call them references. It strongly restricts what
you can do with them. C pointers have an important feature that makes
them very different from the references that Java and most other
languages have: they let the programmer perform address-like
arithmetic on them. You can't use a Java reference to step through an
array, or take the difference between two references.

(Not to mention the unportable but almost universal ability to
convert them to and from integers.)

Just shows that you know nothing about COBOL
- I was surprized to find out what a full instruction set it had

I do not consider the use of SQL to be programming

Yes. Pointers did not even appear in high-level languages until the
mid-60's, except to the extent that they are implied in LISP. A good
many COBOL-turned-to-PL/I programmers don't even know anything to do
with pointers except to subvert the type system.

Even as late as the mid-80's, the designers of Ada felt the need to
justify including pointers in the language, experiences with PL/I and
ALGOL 68 having been bad. (PL/I has been improved since then.)

Well, IBM mainframe COBOL has long included some semi-documented pointer
functions intended for use with CICS.

COBOL 2003 includes OO, and, consequently, references.

But as Pascal is a "safe" language you can't write bad Pascal.... the

There are still far to many people who think that with some languages if

I agree that protecting students with a "safe" language makes matters a

It catches type errors at compile time (for compiled languages), but
it can also be a hinderance at times. I have taken advantage of the
lax typing of JavaScript many times.

Not the same thing at all. Also in many cases you turn OFF the airbags
and don't use seat belts. Though you always want working breaks.

Agreed. I use PC-lint
