If I have to keep track of every method name, and its parameters then I am definitely wasting time on stuff that does not need thinking about.
You are making an implicit statement that with an IDE you don't have to do that, and without an IDE you do. The latter is not the case. When coding a class that calls other classes, you have the other classes or their documentation on screen (rotating through buffers if you are using several in rapid sequence), and they (or their documentation) is cleanly structured so you can find the calls that fit your context quickly.
It is definitely a different way of doing things than using the IDE to autocomplete, but it means you have the target code on screen. That makes it faster to verify fine points of the target functionality when you are not sure what it should be doing and gives an opportunity to catch bugs or mismatches in intent. It essentially inlines code review into the standard workflow, with the most often-used code getting reviewed most often.
I'm not saying it is objectively better for everyone and every context than using an IDE. It's a tradeoff, but it is a valid one with upside that is worthy of consideration.
If you say, "oh but wait you should be able to keep track of the methods." I reply, "yeah please write some professional code!"
Well, I don't think you should keep every method in your head, but to address the latter part of your statement: The system I'm working on at the moment is written in Java, Javascript, Python, Perl, SQL, and some shell scripting, has custom coded EC2 cluster management, does load testing at up to a million calls per second using our standard in-house ten slave cluster, has been run with one hundred of Amazon's largest nodes, and aggregates the results into a central database where they are accessed and charted as they happen.
The fact that you prefer to do it a different way and can write a dandy appeal to ridicule is hardly a compelling argument.
How come JetBrains makes money from providing IDE's that do exactly what the article author is bad?

Well that's bullshit. The biggest problem with development these days is not the language itself, but the 100s of 3rd party mostly-open-source libraries that you have to use. Or else go reinventing the wheel which is worse.

And IDE helps you see the reference for these libraries much easier, using autocomplete and automated documentation lookup. On top of that, navigating your own code is much much easier. Add debuggers and profilers, granted, somewhat less useful in server-side environment but still useful. Semi-automated refactoring though is great, and eclipse does that quite well.

I've done my share of development using nothing more than a text editor. But I prefer to use IDE when I can- they make me much more productive. Of course I still make sure code can be built & deployed using plain command line tools- for Java Maven is great.

An IDE won't make a good programmer write bad code. And it won't make a bad programmer write good code. Unfortunately, a lot of manager types assume that if they buy some expensive tools, their programmers will automatically program gold from straw.

A text editor that does the job IS an IDE by Alkonaut · 2012-10-29 21:58 · Score: 5, Insightful

Most bizarre conclusion I have ever seen. Of course you can have highlighting and other editing tricks (autocomplete, etc.) in a text editor. But once you add things like unit test integration, deployment, and most importantly an interactive debugger where you can step through your code, you have a proper development environment. Running tests can be done at a shell prompt, but debugging not so much. And if your text editor ticks all these boxes, including interactive debugging (I'm sure emacs can for example), then your text editor IS A FREAKING IDE ALREADY. I'd like to make the inverse conclusion of TFA: since we have proper IDE:s we can now allow the code in modern languages to be structured an way we want. A good IDE should never have you worrying about files, just code.

Eclipse failed because projects have to be small.

Curious. My Eclipse project is the Linux Kernel. Works fine.

Tip for young players: Eclipse runs on the JVM, the important bit is the last two letters "VM" - "Virtual Machine". The out of the box configuration gives Eclipse ~128MB of memory.... how many VMs do you run with that much memory? Change the default values to something sane (ie 2GB) and suddenly Eclipse is fast, responsive and useful. Remember VM = Virtual Machine.

TL;DR - Let's all ditch IDEs and go back to Notepad/vi/emacs/edlin.

Code generation in Eclipse is a breeze, it easily creates framework classes where you can plug in your code. Directly jump to classes, view javadoc when you mouseover any element, jump between occurrences of text within a file, seamlessly integrate with the version control system of your choice - it has everything to properly work with a modern software project that can have hundreds or thousands of classes and files.
And the same goes for Netbeans or Visual Studio or any other IDE of choice.

Finally, tell me how many real world projects use Haskell, Clojure or Scala as compared to ones using Java/C/C++/Python/Ruby/PHP/Perl. I don't exactly see dozens of job openings for the former on various job boards. You work with what you've got, unless you're an ivory tower academic who's only concerned with the design of a language as opposed to its real world usage.

Eureka! by Kookus · 2012-10-30 00:06 · Score: 3, Interesting

I think the eureka moment should be when you realize that any language can fall into the trap that you describe. There's reasons for the complexity. Whether they are for compilation/parsing performance, or for some type of design pattern to elegantly solve a problem.

I've got a buddy down the hall who grew up ASP and VB. He uses notepad for development, and complains about not having pointers in Java. Syntax highlighting/completion aside, it takes him forever to write even some of the most basic classes. It's a constant game of finding something to copy and paste. What clicks off in my head is that when you're copying and pasting so much, someone probably already wrote a library for what you were trying to do. Hence additional files, includes, whatever it is... it's more of that whole lots and lots of small files that are mentioned as a downer in the op.

If you're complaining about OO patterns, that's not language specific. Heck, even SAP has an OO equivalent.OO is a byproduct of merging human conceptualization and computer language. It becomes more "natural", arguably, for a developer to understand. Is that a problem of the language? No. I can write just as much spaghetti code as OO in Java, well, pretty much any language for that matter.

Now for your humorous AbstractSingletonProxyFactoryBean. If you're writing a webpage with some fancy graphics on the front and not much user interaction, then you'll probably come across this class and think wtf would anyone ever use it?
If you come from the data processing world with many systems working on the same data, you pretty much don't live without it.

This is equivalent to growing up in Mexico, never even hearing of the word snow, and then see someone walk by with a pair of snowshoes in hand. Do you point and laugh first, or do you try to understand why they have snowshoes?

Snowshoes are obviously everything that is wrong with footwear.

The place where something finally called a method on a null is not necessary place where the bug is. The question is why that variable has a null value at that moment. You will not find it in the stack trace.

If your logic is so complicated that you can't tell where a variable should have been assigned, your code is already an unmanageable mess. Add preconditions on the arguments to your methods and enforce them by throwing an informative exception if they are not satisfied; that helps hugely. If it doesn't, it's time to also do postconditions and invariants. If you don't understand what those preconditions and postconditions should be, that's a much more important problem than where your code is throwing a NullPointerException...

IDEs aren't pure benefit by dbrueck · 2012-10-30 02:46 · Score: 3, Interesting

Modern IDEs can be great, but using them does come at a cost, so I think people end up using them in situations where there is a net benefit (and the opposite is true - people don't use them where there is a net cost to using an IDE). Personally, using a full-fledge IDE often leaves me with a feeling of it getting in the way, but I tolerate it because with some languages or platforms the IDE is still a net win.

This is nothing but an anecdote, but we have several non-trivial projects (100kLOC+ each) in C/C++, C#, ObjC, Java, and Python worked on by about 10 people (so not huge by any means, but not so trivial as to be meaningless) and:

* Everybody uses an IDE for the ObjC, C#, and Java projects
* About half use an IDE for the C/C++ projects (rest use vim)
* Nobody uses an IDE for the Python projects (most use vim)

What's interesting to me is that as far as I know everyone has /tried/ not using an IDE for Java/ObjC/C#, and everyone has tried using an IDE for Python, and there has never been any sort of mandate to go one way or another, and so the present situation is the result of everyone sort of landing where it feels most natural and where they are the most productive, and that we have the same results regardless of proficiency in a particular language (i.e. the C# experts and C# noobs end up with the same development environment, as do the Python experts and the Python noobs). The same also appears to be true regardless of language affinity - lovers and haters of Java use the same environment, lovers and haters of Python do as well, etc.

I do wonder if there is some sort of correlation between environment and the language. I know this is pretty subjective, but for me languages like Python feel like they rarely get in your way, and so it's interesting that when people in our company use Python, they gravitate towards development environments that are similarly lightweight. And conversely, for me a language like Java tends to feel like it gets in the way a lot (as in, you have to do lots of things that are satisfying the demands of the language that aren't directly tied to the problem you're trying to solve), and an IDE is indispensable because the IDE helps shoulder some of that burden.

I'm thinking you've never worked on a multi-threaded application with millions of lines of code. With a debugger, set an exception breakpoint and you can usually see exactly why something bad happened with almost no time wasted on "analysis". If I can reproduce a problem in a debugger I can usually fic it about 10x faster and more reliably than if all I have is a stack trace.
