You are absolutely right. You odnt' have to stop using OO. Point is, you'll start mixing theologies. You'll have objects calling a mess of procedures.
But back to the macro bit. You are right, anything can be made to create a mess... but lemme attack it from the other end. With OOP, an object has its methods on what it can do. If a method calls another objects methods, it's ok. It's straight forward etc... since each object effectively becomes a mini library.
With procedural programming, which what macros are kinda like, code written in place with no object ties, though I know it is inline text replacements, you can have macros call other macros, call objects, call other macros to a very large mess.
Macros do one thing really well.. it allows you to write clean looking code.. in an inline way. But it's easier to write spaghetti code, everything calling everything else with procedural programming. You can effectively create this mess with macro programming.
But you see, that uncertainty, that new language I need to read, is what java develoeprs shouldn't have to deal with. It's like Java and SQL. EJB solves a lot of that, "I need to know SQL to get stuff from the DB." The exception is when you have to define finder functions in your configuration. Point is, it doesn't change how java looks. No syntax changes.
That's prolly what java doesn't want. Syntax changes done by something like macros, or from what you've pointed out.
Yeah, but when you stop using OO and start using Macros, you create a C mess. Procedural programming. If it's done lightly, everything works for the better. If you use it too much.. ewr. It'd require due dilligence of a group of programmers OR a very small grou of programmers doing "the right thing".
I think you ran into the same problem that a lot of Java purists may have. They want java to look like java and not have a language inside the code which does neat syntatical stuff. Not that it's bad intrinsically, after all what is?:)
Lemme also take a segment from what your link has.
(define-syntax (while stx) (syntax-case stx () [(_ test body) #'(letrec ((loop (lambda () (if test (begin body (loop)))))) (loop))] [else (raise-syntax-error 'while "Illegal syntax in while loop" stx)]))
Notice in that code fragment how obvious it is what's happening, even if you don't know Scheme
It's not obvious to us all. I'm slightly confused on what exactly is happening. It looks recusive... though it prolly isn't.
Macros have nothing to do with programming methodology (OOP, procedural, functional, etc).
I understand that macros are an inline replace. But that's what the broad sense of a function is. When you get to this point, perform some functionality. I *know* that a function in c has to deal with throwing stuff on the stack, where as a macro is inline text-replacement.
They look like called procedures.. THAT is my point. they are treated as such by the programmer though the compiler does something totally different, like inline functions.
The problem with macros, is they sorta defeat Java's OOP. Think of it. Defining a symbol, just to be replaced in thousands of other places where it's written, tied only to the global space.
Sounds awfully like a procedure/function to me.
If you tied macros to objects, they'd just be inline methods. So there really is no point.
That depends. If you are working salary, you aren't necessarily being paid to be ther efrom 9-5 or whatever.
It's a culture thing usually. I.e. for sysadmin's, usally it means carrying around a pager or cell, being called on weekends etc, and usually getting compensated.
For developers, sometimes, there is no compensation for donig more hours than doing less hours in the week when work is slow.
So becareful how you decide to work to the letter. It can bite you in strange ways if you dont' read your employee handbook and contract.
It's a plugin that uses XSL and XML for the display layer in struts. IMHO, it forces the MVC (model, view, control) pattern a bit more than JSP (java server pages), since you can embed java IN JSP. Extending XSLT with heavy duty business logic is really REALLY hard.
Problem is, PKWare is prolly a lot smaller than winzip. It's certainly less popular now-a-days. If pkware is much smaller, then why help out winzip? PKware isn't winzip's R&D dept. PKware needs to look out for its best interest, itself.
Cursive is good for one very good reason. You can't have a typing device everywhere you go. Cursive/script is great for writing a little faster than manuscript. Especially for writing notes in class, or in meetings. Typing while in a meeting situation can be considered rude in some places, though not all.
It does not solve writing script TOO fast and making garbage of what should look like script.
It doesn't solve the problem for those who write manuscript faster than script.

FreeBSD 5.1 Released
·
· Score: 3, Insightful
Note: you typically install/upgrade freebsd via either
1. cvs (cvsup). It only gets the newer files. 2. The tarball packages. (i.e. bin.aa.gz or something like that)
ISO's don't usually get made every waking moment. It's more FBSD culture to use cvs..., so bittorrent wouldn't excel here, unless someone tarballed the distrib..
I've never had a problem with light not.. lighting the screen when a lamp is on it. The problem is either it's not bright enough, i.e. for the first castlevania game or glare. Not many games are that dark.. and as for glare, tilt the gameboy or yourself a different direction.
If every company wrote their own web server, that'd be stupid. But when a solution needs to be written due to a technical requirement or a business requirement, that will be more likely unique.
Lets take, something like.. the Java API. CPAN is quite huge and has all the tools that perl has. But someone came along and said, "We need a business language, that we can make money off of [ 2) ???? ] and fulfill a bunhc of things, like OOP and such." Thus, java was born.
Now you ahve two tools that can do the same thing, near line-by-line if you want them to. Yes, there are things you can do in one language, and not in others, but it can be done.
Now I want to start a company that sells ERP software. It's been done before, but I think I can provide something that other people can't. THAT is what is unique and why the wheel is reinvented. My software does something better, or at all, fulfilling a requirement.
Problem is, you can't strip out my "better stuff" and paste it on. That'd be like, using word for some things, wordperfect for others, and finally, use abiword for finishing touches. It'd either be economically stupid or impossible.
Ok, so you're a super-parent then. Day and night there's never 2 seconds you're away from you child protecting them from the dangers of the world. Will to sacrifice EVERY bit of life you have to make sure they aren't subjected to deadly television radiation. Man, that kid is going to be sooooo messed up as an adult.
You just described the extreme alternative. What (s)he was trying to say is, instead of letting a kid use games etc.. instead of social interaction all the time, take time out of your day and the child's and interact with them.
Doesn't have to be 90% of the day. Hell, even one or two hours.

Ok, I'll bite. How do you tie = or == to an object syntatically?
:)
this->==(something) ? this->equals(something) already exists
Just to clarify further why macro's are bad.

Yeah, but you also have to worry about "noise", unwanted junk on the channel.

Yes you can.
Update your cvsup source tree to 5.1. Before doing a "make world" etc.. look for files such as README, UPDATING etc.. they are in all caps.
They should tell you things like, binary incompatabilities.

You'll live.
Get some rechargable batteries and a lamp. Use it. You'll live.
Or use your m4d h4XX0r1ng skilz and get an afterburner lighting kit for it.
Obviously, you named ReiserFS after yourself. Why after yourself? Were there any runner-ups? What will happen when you create another great project? :)
I totally agree to some degree. :)
