Comments from Stephane Ducasse This book covers all kinds of issues basic level, design, testing I liked it a lot. The code and the book as a single file containing everything are available. Thank again Lukas Renggli for his effort for converting everything from Word. Not all the publishers are that open-minded.

This book is distributed under the Creative Commons license and it would be nice to translate it in other languages. If you like it, we recommend to buy it, we are proud of this kind of projects.

Sometimes luck intervenes and a meeting with a mentor causes a great advance in one's abilities. However, there are only so many of these rare encounters and thus this opportunity cannot possibly come to everyone. This book is an attempt to remove having luck as a limiting factor for one's professional growth in Smalltalk, by creating an explicit form for the material received over the course of several years of mentoring.

The thorough treatment also describes the method to efficiently develop new skills, and exemplifies valuable lessons learned over more than a decade of experience. Comments from Stephane Ducasse Ivan wrote this book and he gave it to the community. It contains a lot of useful material. Thanks again ivan and continue to write good books. Online Book We are making this book available to you for free. You can soon obtain a printed copy through lulu.

We are looking for additional sponsors. If you are interested, please contact us. If you are a publisher interested in publishing this material, please contact us. Advanced books Books that are oriented in a topic in specific of Smalltalk.

The first part develops hashing and hash functions from first principles. The behavior characteristics required of hash functions are examined in detail. A thorough description of how hash functions are constructed follows, complete with a rich survey of existing hash functions. But often times existing hash functions are inappropriate for the task at hand. To address this problem, the second part shows how to build novel hash functions that are both efficient and of very high quality for many of the types of data that occur in practice.

The book includes over exercises. Together with their answers, provided in an appendix, they further develop the material in often unexpected ways. While the programming language used in this book is Smalltalk, the information provided applies to other programming languages as well.

Comments from Stephane Ducasse A great and small book that everybody should read. Thanks Ed, Suzanne and Dave to give it for free. Note: If you are a long-time user of SqueakSSL, you will want to update both the SqueakSSL packages as well as download the latest plugin since there have been a few changes done for this article. The biggest difference is in handling certificates which is poorly documented by Microsoft and often a guessing game. So before we begin with the actual content we need a brief introduction to working with certificates on Windows:.

Creating Certificates Windows uses mostly. Your CA if you bought a certificate might be able to give you one right away but often you will end up with a. Fortunately, this can be done using the OpenSSL toolchain. For example, when converting mycert. And if you have any other certificates that you need to convert, spend some time with the openssl documentation.

Next, open the explorer and navigate to the. You should make sure that the icon for the file includes a little key in it — what that means is that the certificate includes a private key which is required for the use by SqueakSSL. If the certificate has no private key it will not work. Double-click on the file to import it into the certificate store.

This will open the Certificate Import Wizard. Go through the Wizard all the defaults should be okay and the import should complete successfully. Finding Certificates Once imported you will want to check that the certificate is in the proper location. Unfortunately, Microsoft makes finding certificates amazingly difficult. Inside MMC, you will now see the certificates. You should be able to see your imported certificate like here:. Note that you can import certificates from here as well.

This is important since the friendly name is what will be used by SqueakSSL to select the proper certificate. Using the Certificate Once you have installed the certificate, you can follow the instructions from the previous post with the following adjustments:. Posted in Uncategorized Leave a Comment ». This is the first part of our series about the Cool bits of OpenQwaq. OpenQwaq has a complete integration with Python. What this means is that from OpenQwaq you can call Python code simply via something like here:.

The bridge also allows callbacks from Python into Squeak code. From the Python you can talk back to Squeak like here:. OpenQwaq picks it up via the Python callback process and delivers it the proper receiver. There is lots of fun stuff you can do that way. The best way to experiment with it, is to simply play around and inspect various results of operations. Posted in OpenQwaq Leave a Comment ». Most of you have probably seen the announcement that the OpenQwaq Project is now available.

Posted in OpenQwaq 1 Comment ». Happy everyone! Since I had done this at work before via a plugin interface to support both Windows and Mac transparently I figured it would be straightforward to implement it using the Squeak FFI interface. And indeed it is. A Monticello code repository for Squeak. Others you may find at SqueakMap or the now retired SqueakSource1. Using the Git Browser , you can commit and browse your code and changes in Git and work on projects hosted on platforms like GitHub.

With Monticello you can read and write FileTree and Tonel formatted repositories in any file-based version control system. Square Bracket Associates, You can always take a look at the progress in the latest alpha version. Feel free to participate with commits to the inbox. Alpha versions are not expected to be stable. Make sure to also get the latest VM. Everything is an object. Objects collaborate by exchanging messages to achieve the desired application behavior.

The Smalltalk programming language has a concise syntax and simple execution semantics. The Smalltalk system is implemented in itself: Compiler, debugger, programming tools, and so on are all Smalltalk code the user can read and modify.

Novice programmers can get started easily and experts can engineer elegant solutions at large. All graphical objects are tangible and interactively changeable. This promotes short feedback loops and low-effort application development. Morphic thus leverages the live programming experience of traditional Smalltalk environments from a mainly text-focused domain to a graphical one.

The dynamic Squeak environment provides a variety of tools for browsing, writing, executing, and versioning Smalltalk code. Multiple debugging sessions can be served concurrently. Thanks to Morphic, tool customization can be achieved with reasonable effort. There are several fast Squeak VMs that also support other languages of the Smalltalk family. Meta-tracing, just-in-time compilation, stack-to-register mapping, and aggressive in-line message caching yield efficiency in executing Smalltalk byte code.
