CalipeL: a benchmarking tool for Smalltalk/X and Pharo
Hi there, After more than 2 years of (time-to-time) development and about that much time of use, I'd like to announce CalipeL, a tool for benchmarking and monitoring performance regressions. The basic ideas that drove the development: * Benchmarking and (especially) interpreting benchmark results is always a monkey business. The tool should produce raw numbers, letting the user to use whichever statistics she need to make up (desired) results. * Benchmark results should be kept and managed at a single place so one can view and retrieve all past benchmark results pretty much the same way as one can view and retrieve past versions of the software from a source code management tool. Features: - simple - creating a benchmark is as simple as writing a method in a class - flexible - a special set-up and/or warm-up routines could be specified at benchmark-level as well as set of parameters to allow fine-grained measurements under different conditions - batch runner - contains a batch runner allowing one to run benchmarks from a command line or at CI servers such as Jenkins. - web - comes with simple web interface to gather and process benchmark results. However, the web application would deserve some more work. Repository: https://bitbucket.org/janvrany/jv-calipel http://smalltalkhub.com/#!/~JanVrany/CalipeL-S (read-only export from the above and Pharo-specific code) More information: https://bitbucket.org/janvrany/jv-calipel/wiki/Home I have been using CalipeL for benchmarking and keeping track of performance of Smalltalk/X VM, STX:LIBJAVA, a PetitParser compiler and other code I was working over the time. Finally, I'd like to thank to Marcel Hlopko for his work on the web application and Jan Kurs for his comments. I hope some of you may find it useful. If you have any comments or questions, do not hesitate and let me know! Regards, Jan

New Brick Preview
Hi
A small technical Brick preview 🙂
What is new:
– Refactored and improved layouts. Now they also work with views
– Text editor widget
– List performance improvements
– Many new examples
– Rewrote tests.
They are visual and displayed as examples in browser.
– Improved example browser.
Examples are categorised in expandable tree list.
Added example hints.
– Many small improvements and bug fixes
Gofer itsmalltalkhubUser: ‘Pharo’ project: ‘Brick’;configurationOf: ‘Brick’;loadDevelopment.
Please note, it is impossible to load brick in Pharo for a moment because of upcoming integration of GT. (Brick uses new GT stuff which is not in pharo yet). Please use Moose 6.
I also added brick examples entry to world menu.

HTTPS proxying using HTTP CONNECT
Hi, Yesterday I did a first implementation of HTTPS proxying using HTTP CONNECT tunneling for Zn+Zdc, this should now be tested by a wider audience. With this new feature it should now be possible to access HTTPS Urls from behind an HTTP proxy. This is for all OS platforms. Thanks Nicolai for finding the spec reference and Torsten for the push.

A warm testimony
Hello Offray,
My apologies for the delay in reply. I have been on holiday.
Thanks for the suggestions. I am pretty much wanting to stick with Pharo solutions. I want to use and contribute to the Pharo ecosystem.
I believe the more we use our own tools and contribute toward the ecosystem the better our tools and the ecosystem will be. In Pharo I can possibly offer an occasional bug fix, contribute to documentation or tests.
And yes, the other solutions do offer that as well as they are open source. But the bar is much higher. I now have to understand their ecosystems, languages, and development cultures of a variety of tools.
In Pharo I have Pharo/Smalltalk. Even a simple user can often contribute in simple ways. Even as a simple user of a Pharo tool. I can submit issues, fix simple issues, improve method or class comments, etc. As I learn the Pharo tools and ecosystem I continually improve my ability to take care of myself and also contribute to the community. I think Pharo is the most user empowering environment I have found. Sure I can find lots and lots of other quality tools in other languages. But each is their own island. And depending on how broadly I spread the net. Different languages, different cultures, different licenses, all independent of each other.
I much prefer the Pharo ecosystem and culture. It is home.
I know others who like the other tools, and multiplicity of choice. And they feel comfortable there.
Choice is nice. Pharo is mine.
Thanks again for suggestions and for a view on how others approach problems and their solutions. That is always available as inspiration even within Pharo. I take a look at your stuff.
Jimmie
