Moose 5.1 image getting really sluggish after graphing a bigger dataset

by Manfred Kröhnert

Hi everyone, after having access to a machine running OS X 10.10.2 I started to give Moose 5.1 a try for some initial data analysis. I used Pharo Launcher (build #24) and downloaded the Moose image with buildnumber 304. The task is to read a CSV log file containing around 130000 entries, each containing a timestamp, a cpu usage number, and some other information. Everything works as expected, but the responsiveness of the image drops dramatically after executing the script in Playground with Cmd+Shift+g. After evaluating the script it takes several seconds to get a response to any action such as opening the world menu or switching tabs in the playground. Is this because I am doing something very inefficient (most probably) or does this problem occur more often? Here is the script I am using: cpuReader := NeoCSVReader on: (cpuFile readStream). cpuReader separator: $|. cpuHeader := cpuReader readHeader. cpuData := cpuReader upToEnd. g := RTGrapher new. g extent: 300@200. ds := RTDataSet new. ds points: (cpuData collect: [ :each | | timestamp cpuUsage | timestamp := (each at: 1) asNumber. cpuUsage := (each at: 4) asNumber. Array braceWith: timestamp with: cpuUsage]). ds x: #first. ds y: #second. ds connectColor: Color blue. g add: ds. g addDecorator: RTHorizontalTickLineDecorator new. g addDecorator: RTVerticalTickLineDecorator new. g build. g view canvas. I also noticed that the 'Meta' representation of an object looks very crammed since it does not use the full size available in the tab. Should issues like this be reported somewhere else? Thanks for taking a look at this, Manfred

500 000 elements in Roassal [we made it :-) ]

by Alexandre Bergel

Hi! Just to share our latest feature. We have implemented a simple mechanism in Roassal to prevent the environment to be sluggish with many elements. The class RTCache has the effect to remove the elements from a view, create a bitmap from them, and add the bitmap to the view. Simple and effective. Consider the following script: -=-=—=-=-=—=-=-=—=-=-=—=-=-=—= v := RTView new. v @ RTDraggableView. colors := ColorPalette qualitative colors: 8 scheme:'Set1'. elements := (RTEllipse new color: [ :aValue | colors atRandom alpha: 0.01 ]; size: #yourself) elementsOn: ((1 to: 500000) collect: [ :vv | 10 atRandom + 5 ]). elements do: [ :e | e translateTo: 500 atRandom @ 500 atRandom ]. v addAll: elements. RTCache new cacheView: v. v -=-=—=-=-=—=-=-=—=-=-=—=-=-=—= Without the line "RTCache new cacheView: v.” Pharo would be completely unresponsive. 500 000 elements is quite a lot. The drawback is that all interaction with the elements are lost. I have some idea on how to add them back. We will work on this in future work.

Tag cloud around an avatar

by Offray Vladimir Luna Cárdenas

Hi, I would like to create a tag cloud around an avatar taken from the public profile of a social network (twitter). For that I would like to know if is possible to make 3 things in Roassal: 1. Put a tag cloud with some layout/form (for example around an object). 2. Put a raster image (the avatar) in the center of that tag cloud. 3. Exclude some words from the tag cloud. I will be making my explorations tonight and tomorrow morning, but any pointer in the right direction will be greatly appreciated. Cheers, Offray

spotter scenario

by Alexandre Bergel

Hi! I am facing a scenario that spotter does not seem to help. Consider the following scenario: - Consider the Moose Panel menu: - I would like to know how to add a new entry in that menu. Best is to look for existing example. So, I would like to see the class behind the entry “import hismo model from MSE files”. I highly suspect that the class contains the word “Hismo” and “Import” in it. Well, let’s see what spotter gives me. - I open Spotter and enter: hismo import Instead, I open Nautilus, typed Importer, and found it: It is MooseHismoImporter. Well, from this class, I end up in MPImportHismoCommand, which is exactly what I am looking for Did I miss anything obvious in my reasoning?

Hi Again :-) So, I compiled a fraction of the BBC News JavaScript application. And I started to visualize their JavaScript application.

Google code will close!

by stepharo

Begin forwarded message: From: google-code-noreply(a)google.com Subject: Google Code shutting down Date: 13 Mar 2015 02:11:08 GMT+1 To: stephane.ducasse(a)gmail.com Reply-To: google-code-noreply(a)google.com Google Code Hello, Earlier today, Google announced we will be turning down Google Code Project Hosting. The service started in 2006 with the goal of providing a scalable and reliable way of hosting open source projects. Since that time, millions of people have contributed to open source projects hosted on the site. But a lot has changed since 2006. In the past nine years, many other options for hosting open source projects have popped up, along with vibrant communities of developers. It’s time to recognize that Google Code’s mission to provide open source projects a home has been accomplished by others, such as GitHub and Bitbucket. We will be shutting down Google Code over the coming months. Starting today, the site will no longer accept new projects, but will remain functionally unchanged until August 2015. After that, project data will be read-only. Early next year, the site will shut down, but project data will be available for download in an archive format. As the owner of the following projects, you have several options for migrating your data. pier google-summer-of-code-2008-squeak google-summer-of-code-2007-squeak bluecoral seasidexul moose-technology The simplest option would be to use the Google Code Exporter, a new tool that will allow you to export your projects directly to GitHub. Alternatively, we have documentation on how to migrate to other services — GitHub, Bitbucket, and SourceForge — manually. For more information, please see the Google Open Source blog or contact google-code-shutdown(a)google.com. -The Google Code team Google Inc. 1600 Amphitheatre Parkway, Mountain View, CA 94043 You have received this mandatory email service announcement to update you about important changes to Google Code Project Hosting.
