Will the future start to happen ...
There is a new webcast presentation available on Croquet technology build in Squeak Smalltalk. I'm not sure which impact this technology will have on computing in the next years but I think it would be wise for many companies to have a look at it before their competitors do...

Today's (Smalltalk) IDE's Part II
The discussion about the power of Smalltalk IDE's continues. Some comments again:
Looks like Talios only accepts an IDE as powerfull if it supports auto completion. Dolphin Smalltalk may have some problems here. But why generalize then?
The eCompletion (Eclipse style completion) package from Squeak works quite nicely and only shows the appropriate selectors:
But there are cases where auto completion is not able to quess the type of an object (for instance when you play with reflection).
I dont claim Smalltalk IDE's to be the holy grail, but compared to other IDE's they are flexible and open. If it doesnt work in Dolphin you can change the auto completion very easily. Ever tried to change the auto completion of VisualStudio? ;)

Today's (Smalltalk) IDE's
I'm not sure why Cedric Beust (whoever this guy is) should be one of the forward thinkers in the Java community when he says something like this in an interview:
"A lot of veteran developers point out that Smalltalk showed that it was possible to have such an IDE in a dynamic language, but they are only partially right. Today's IDE's are doing much more than anything Smalltalk's environment ever did, so the problem is still wide open (and maybe impossible to solve)."
I used/use both: Smalltalk IDE's and Eclipse/VisualStudio like IDE's - also wrote plugins/goodies/tools for both (including an own standalone IDE). So I know what I'm talking about and have to disagree:
Today's IDE's are doing nothing more than Smalltalk IDE's in the past and present and will never be able to do more than a Smalltalk IDE in the future!
You ask why? Here is my answer:
One can easily build tools in a Smalltalk IDE without spending much time or relying on a predefined plugin architecture. That's why so many features in 'modern' IDE's have their history in Smalltalk. You can also modify the predefined Smalltalk tools to suit your needs since they come with full source code and are easily changeable.
(Ever tried to fix a bug in an Eclipse core package or plugin and you know what I'm talking about)
If there is no predefined Smalltalk tool for your task you can also write a simple script and run it. An example? Let's delete all (S)Unit test cases currently implemented using a single line of code:
Or maybe you need some statistics for your boss: let's count the number of SUnit test case classes in the system:
You can easily access the compiler:
or directly evalute your code in a workspace.
Another example: you want to know how long a particular action or piece of code will take, so just write a profiler script or add the profiler into the particular method:
Next example: we want to watch an object. So just send
to open an inspector showing the object and it's structure. We can also open a browser on the object's class by sending
browsing the behavior and send new messages after that.
Try to do all this in VisualStudio or Eclipse. Even with additional script support added by the vendor/community you will never get the flexibilty of a Smalltalk IDE where you can access anything, including your projects, packages, classes, methods, files and not to forget the language itself. Other scriptable IDE's are mostly limited to predefined objects exposed by the IDE.
And you dont need to know a different scripting language with a different syntax. In a Smalltalk IDE you can use one simple and powerfull language to develop your program, enhance the IDE with tools, build your program and packages and deploy it, ...
So additional stuff like plugin architectures, build systems based on XML (Ant), setup managers, ... are not necessary in Smalltalk. Just use Smalltalk.
In a Smalltalk system there is also no difference between the IDE and the developed application. Typically you throw the IDE out of the image (where any object lives in) before delivering the application. Sometimes an IDE tool is also usefull for the end user of your application so you just leave it there. If you want you can leave the debugger or the whole IDE tools in the deployed application. So you can track problems happening only on the customer side, directly fix them in the debugger and continue running the application...
To transform this example into the java world: try to build and deliver an Eclipse RCP application with the java debugger included, fixing a bug and continue without restarting ...
This is mostly the problem developers from traditionall IDE's face when working with a Smalltalk IDE for the first time. They are too much bound to code in files, IDE tools like a compiler or a debugger as separate application, ...
Maybe some of the Smalltalk IDE's have to catch up with a better look or provide some newbee wizards and templates found in other commercial IDE's. Maybe then people like Cedric Beust will accept to work with them and learn about the power of Smalltalk.
Cees also wonders why anyone is wasting time interviewing this Cedric Beust.

SqueakSource Server image
I managed to build a working SqueakSource server image using the instructions from http://source.squeakfoundation.org.
With this predefined image you are able to run an own local SqueakSource repository server very easily.
Cees De Groot will host the image and put a download link onto the project page tomorrow. Here is a short preview of the image and the server running on localhost:
Many thanks to Doug Way for the instructions, the SqueakSource authors for this nice piece of Software, Cees for hosting and others who helped to make it available.

Techo with Shout
Found a nice tool on SqueakMap today. It is called "Techo" - something like
a multi notepad. Many thanks to Takashi Yamamiya for implementing this little tool.
Since I want to use it as a workspace script manager I created a "Shout" and "eCompletion"
aware version of it to support Smalltalk syntax highlighting.
To install in Squeak 3.8#6665 using the SM Package loader:
- install "Shout" version 4 (may already be installed)
- install "ShoutWorkspace" version 2
- install "eCompletion" version 2.0b2
- install "TechoShout" version 1
Open Techo using 'open' in the world menu or evaluate "Techo open".
Now you can create workspace scripts. Note that Techo used the first line
as the name for the script - so I typically write the scripts using a first line comment:
a multi notepad. Many thanks to Takashi Yamamiya for implementing this little tool.

Reimplementing Eclipse?
If they really want to bring more Smalltalk experience into Eclipse I would vote for reimplementing it using a pure and dynamic OO language. ;)
Maybe they should have a look at Squeak - it's open source, not controlled by vendors and it's community is growing fast.

Seaside in O'Reilly article
Seaside (the Smalltalk web framework based on Squeak) is mentioned in an O'Reilly article:
"Web programming is an absolute disaster. After ten years of Java programming, we still haven't built a framework to get the Back button right. Web applications are stateless, so web applications scale better. But stateless applications are hard to build, and our frameworks do not give us much help. With most Java web frameworks, you basically build many unrelated pieces of the application using servlets or JSP, and then wire them together by manually saving objects that you need in temporary storage objects called sessions."
...
"Continuation-based web frameworks generally make web development much easier by simulating a stateful application."
...
"The best continuation-based frameworks are developed in dynamic languages. By far, the most robust is Seaside. It's a framework based on Squeak, a Smalltalk dialect. Seaside features fantastic debugging support--you can actually inspect, debug, and change your code from a browser"
I also like the Conclusion:
"In Beyond Java, I make the case that Java's not dead yet, but for the first time in nearly a decade, we're seeing compelling innovation happen beyond the borders of Java. These four technologies will play an important role in the near future. Watch them closely."
But I would not totally agree: in Smalltalk innovation happens all the time!

Yet another frustrated developer...
Currently Java (especially J2EE) is getting too complex and this will frustrate more and more developers.
It is true that compared to Java you are much more productive - but Smalltalk is still the winner for developer productivity. It is also much easier to use - if you are willing to think in plain objects and messages. So leave the curly braces behind you and start by reading one of the free Smalltalk books.

Writing customized UI's using Morphic
Had a little bit time this evening. Not enough to do anything serious with Smalltalk - but enough to answer a question on the Squeak mailing list by writing a simplified "Handy Simulator". It's only behavior is to switch the screen on and off by using the power button.
It's a nice example of using morphic to build a customized user interface. The package is registered on SqueakSource and can directly be loaded into squeak using the SqueakMap package browser.

Is Eclipse the next computer revolution ...
James Governor blogs about Eclipse and he is so excited about it that he calls it
the next computer revolution.
I dont think Eclipse is a revolution - it only assembles good ideas mixed with good marketing. Nothing really new. It also helps Java developers finding more acceptance for their applications by providing a native look.
Even with nice plugins Eclipse is still not the most powerfull tool since it's weakest point is IMHO Java. That wont change - even with the money of respected IT vendors.
Any Smalltalk IDE is much more flexible as a system since it is based on pure objects not on files, static typing and static languages. Some questions you should ask yourself:
Can I fix a bug in Eclipse itself while it is running without restarting or debugging from another eclipse session? Can I add a feature to the debugger even when there is no extension point defined - just since I have to fix it or want to include a tool I need for faster development?
Can I save the complete object environment (Object memory) in an image while debugging and continue debugging at exactly the same point the next day or on a different computer?
Can I add a new control structure to the underlying language while the IDE is running and without changing the parser/scanner/compiler?
Can I script the whole Eclipse environment like I can change any Smalltalk IDE using the Smalltalk language. In Smalltalk I can write:
TestCase allSubclasses do:
[:each each removeFromSystem]
to get rid of all unit tests in the IDE for example? I also use the same language to build and deploy my applications. There is no need for a different technology like Ant and remembering xml-tags/ant tasks. Anything is open, accessible and changeable. Even the language itself is just assembled from objects.
I agree that Eclipse does a good job in providing a nice platform for RC applications, frameworks and tools. Nothing else. But people should have a look at more dynamic environments since our world is constantly changing and so should our tools.
Just download a Smalltalk system like Squeak or VisualWorks and try it for yourself. Or have a look at: http://www.opencroquet.org. Download and try it. I would call Croquet a revolution, but not Eclipse.
But as Alan Kay says:
"The Computer "Revolution" Hasn't Happened Yet!" (see http://en.wikipedia.org/wiki/Alan_Kay)
the next computer revolution.
I dont think Eclipse is a revolution - it only assembles good ideas mixed with good marketing. Nothing really new. It also helps Java developers finding more acceptance for their applications by providing a native look.
Even with nice plugins Eclipse is still not the most powerfull tool since it's weakest point is IMHO Java. That wont change - even with the money of respected IT vendors.
Any Smalltalk IDE is much more flexible as a system since it is based on pure objects not on files, static typing and static languages. Some questions you should ask yourself:
Can I fix a bug in Eclipse itself while it is running without restarting or debugging from another eclipse session? Can I add a feature to the debugger even when there is no extension point defined - just since I have to fix it or want to include a tool I need for faster development?
Can I save the complete object environment (Object memory) in an image while debugging and continue debugging at exactly the same point the next day or on a different computer?
Can I add a new control structure to the underlying language while the IDE is running and without changing the parser/scanner/compiler?
Can I script the whole Eclipse environment like I can change any Smalltalk IDE using the Smalltalk language. In Smalltalk I can write:
TestCase allSubclasses do:
[:each each removeFromSystem]
to get rid of all unit tests in the IDE for example? I also use the same language to build and deploy my applications. There is no need for a different technology like Ant and remembering xml-tags/ant tasks. Anything is open, accessible and changeable. Even the language itself is just assembled from objects.
I agree that Eclipse does a good job in providing a nice platform for RC applications, frameworks and tools. Nothing else. But people should have a look at more dynamic environments since our world is constantly changing and so should our tools.
Just download a Smalltalk system like Squeak or VisualWorks and try it for yourself. Or have a look at: http://www.opencroquet.org. Download and try it. I would call Croquet a revolution, but not Eclipse.
But as Alan Kay says:
"The Computer "Revolution" Hasn't Happened Yet!" (see http://en.wikipedia.org/wiki/Alan_Kay)
Squeak on Google Video
There are now two Squeaky videos on Google Video:

(a short Seaside Demo by Stefan Ducasse and a half-hour demo from Marcus Denker at EuroKo03. Nothing great, this was more for testing. More to come.

TOPLAP and Squeak
TOPLAP - an informally-organized group collective of software artists and musicians interested in the performative nature of algorithms met in Berlin. Craig Latta (Squeaker and music composer) took part on this event. There is a first video available giving you an impression on how to create music performances using Squeak and other live coding environments.

Another frustrated Java developer...
Instead of being frustrated and running in circles on the Java islands
more people should have a walk on the seaside and have a Smalltalk. See:

Bitwise Magazine and Smalltalk
The Bitwise (www.bitwisemag.com) magazine, which launched online last week, has a two part beginners' tutorial to Smalltalk. Based around Squeak, this is very much intended for complete newcomers to the language. However, they also plan to review the forthcoming Dolphin Smalltalk v 6.0, and to have a feature on Cincom Smalltalk some time in the next few months.

Some news from OSVM
The OO VM (now known as OSVM) from Lars Bak is getting more attention. It's a smalltalk VM with some restrictions for blocks. Read more here. If it is possible to build Smalltalk VM's in 32kB why not build a small, full functional and portable Smalltalk VM for plugging into web servers and other applications?

Hopefully they will stop trying to give me money when they read my answer:
Dear Mr. Howard,
unfortunately I have to decline your offer since I dont think
it is worth the effort. I earn more money in my daily job -
which is sending stupid emails to other people and making them
believe they could esily get rich. I typically use free mail
accounts to send these messages around telling people that
I represent a company searching for reliable representatives.
Unfortunately my job get's harder these days since it is not
a new idea and most people dont want to get rich - typically
they send me an answer that they do the same job as I do and
have to decline my offer...
Very Respectfully,
Mr. John Massmailer
