Our next goal is to represent GPS coordinate and cities. We will then
probably try to show some visually interesting data (e.g., flights, tweets).
Having this run at the top of Roassal @ Amber will come for free. Stay tuned!

Athens more into Roassal.
There are free shapefile maps in sites like this

It is rendered with Athens, although it should certainly work without, I haven't tried. I haven't used bitmap, which means you should be able to zoom in and out as you wish.

On Nov 25, 2013, at 1:46 PM, Clément Bera bera.clem...@gmail.com wrote: Hello, To answer your question, V8 definitely supports memory segments. I don't know about papers but in the code each segment is an instance of Heap (see heap.cc and heap.h in the source). The 2 young spaces are in another contiguous segment of 8Mb. Each segment of V8 are one of this kind (all instances of Heap): * NewSpace: New object allocations go here. Capacity is 8MB. It's divided into two contiguous semispaces, and periodically collected using Cheney's algorithm. Uses bump-allocation. * OldSpaces: These allocate memory in 64-128KB chunks of 8KB pages. They come in the following flavors: * MapSpace: Exclusively for Maps (similar to js::Shape), and Maps *always* go here. * CodeSpace:Exclusively for Code. * DataSpace:For flat strings and numbers; can't reference objects, except for maps. * PointerSpace: For anything not a Map or Code that can reference other objects. * CellSpace:Seems to store global properties or something. * LOSpace: For large objects, where large means it needs more than ~8KB of storage. I have no proof for hotspot (their code is too complex) but I'm sure they have it too. For the other question (adding elements to OrderedCollection), Eliot will answer it in more details, but the main idea is that you have the heap chopped into segments of a fixed size (1Mb in Cog, and 64-128KB chunks in V8), therefore for object bigger than a segment, you need to handle specifically the object, i.e. having a segment of the size of the object. If you add 30 000 elements to an OrderedCollection, the object will still be under 1MB so it is ok, now if you a 3 million of elements to this OrderedCollection, you need to handle specifically, Therefore you have performance loss for object of more than 1Mb but there are not common so you will not notice it (you can hardly have thousands of objects bigger than 1Mb allocated and deallocated regularly, and you need this amount to notice the performance loss). An interesting point in V8 is that the data and pointers are not in the same spaces. It would mean in Cog, if I understand correctly, that byte and word objects are not in the same space as other objects. I guess this simplifies the GC logic. I don't know if they did that in VW. 2013/11/25 Alexandre Bergel alexandre.ber...@me.com Hi Eliot, I have a question still on segmented memory. Consider an object “c := OrderedCollection new”.

Do you feel this may be a problem? I am thinking about a long jump between c and array. Long jumps cost more than short jumps right? I don't think it'll be an issue because statistically it'll affect a minority of collections. No, its not necessarily the case that there may be a higher cost. This depends on how the processor's memory hierarchy works. Further, performance may be more affected by how clustered the elements of the collection are than the collection itself. Ah okay. What do you mean by how the elements are clustered? Do you feel there are some suboptimal situation with this situation? I think it's way too early to worry about this kind of thing. The system needs to work and be tuned. There's plenty of time to address clustering, etc. I am not sure to understand what clustering means here. Thanks again for taking the time to answer questions.

Re: [Pharo-dev] Understanding Roassal
Hi! So I took your advice and gave a good look to Roassal to learn more about how to use Athens. First I want to congratulate the coders, I was expecting a simple visualisation library for object graphs and what I see is a full blown graphics library that can be used for many diffirent kinds of graphical illustrations. Thanks for your nice words :-) I still however trying to understand the end goal of Roassal , is there an end goal or is it generally code visualisation ? The goal of Roassal is getting broader with the time. The main objective of Roassal is to be a platform for data visualisation. So, as soon as you have a bunch of data (e.g., plenty of numbers or any arbitrary objects), then Roassal should give you the tools to visualize and interact with your data. Roassal is slowly moving from a tool for end-user to a platform on which domain specific languages can be created. This is an important point when reusing visualizations (e.g., ROTreeMapBuilder, ROMapBuilder, ROMondrianViewBuilder are all compelling examples). Roassal is currently being ported to Amber, which will probably broaden the vision behind Roassal. Early examples may be found on: http://pestefo.github.io/roamber/# Also I wanted to ask if Roassal can do visual coding. By that I mean visualize not only objects but messages inside methods so the users with drag and drop code in a visual way. Yes, Roassal is made for that. If there is something that Roassal does not allow you to do, then let us know, we are a whole team ready to polish Roassal. I took a look at the examples but I see nowhere the use of bezier curves , why is that ? There is a few. Try: -=-=-=-=-=-=-=-=-=-=-=-= Source code: ROMondrianExamplebezierCurveOn: Preambule. It includes the initialization. | view rawView | rawView := ROView new. view := ROMondrianViewBuilder view: rawView. - - view shape circle size: 10. view nodes: (Collection withAllSubclasses). view shape bezierLine. view edgesFrom: #superclass. view radialTreeLayout. view center. - - Below is the initiation of the menu and opening the visualization ROEaselMorphic new populateMenuOn: view. view open -=-=-=-=-=-=-=-=-=-=-=-= Have a look at the class ROSplineExample It does not contains many examples, but you get enough to build appealing visualization (e.g., https://www.facebook.com/media/set/?set=a.511442275609041.1073741827.340543479365589type=3 ) More screenshots are available on: https://www.facebook.com/ObjectProfile Cheers, Alexandre

After the addition the array will be very very big. Which means that it may be in a different segment memory than the one that contains “c”. Do you feel this may be a problem? I am thinking about a long jump between c and array. Long jumps cost more than short jumps right? I don't think it'll be an issue because statistically it'll affect a minority of collections. No, its not necessarily the case that there may be a higher cost. This depends on how the processor's memory hierarchy works. Further, performance may be more affected by how clustered the elements of the collection are than the collection itself. Ah okay. What do you mean by how the elements are clustered? Do you feel there are some suboptimal situation with this situation? I think it's way too early to worry about this kind of thing. The system needs to work and be tuned. There's plenty of time to address clustering, etc. I am not sure to understand what clustering means here. Basically it means how close an elements of collection in memory - the closer, the better. Of course it only will have effect if you using collection for iterating over it (like do: etc).. But if you using it for random access, there's not much CPU hardware can do in order to optimize access to it, especially when speaking about very large collections with millions of entries.

In particular making the VM support fragmented memory. If I understand correctly, this will relieve the VM from having a continuous block of memory to hold the whole image. Really cool! A better term is segmented memory. fragmentation in memory management means free space getting divided into too small pieces to be useful. I have a general question regarding VM. Are you aware of other Virtual machines supporting this? Does the Java VM support fragmented memory? .Net? V8? Any VM that uses the train algorithm supports segmented memory. Any VM that uses pools or regions uses segmented memory. VisualWorks' VM supports segments. I'm pretty sure that V8 .Net HotSpot provide segmented memory. I would like to mention this in a research paper I am working on.

Re: [Pharo-dev] Understanding Roassal
Yes I am interested in Amber Roassal and also Roassal3d. Mostly on Amber Roassal because I want to target tablets and phones and since I have no desire to go through the App stores, javascript is my best option.

Hi! Is your team open to external contributions as well ? Yes, absolutely. Roassal already contains many contributions. I am still exploring 2 options a) to use Roassal as a way to learn Athens b) to use Roassal as a basis for my project I did not expect that you would take such a generic approach to graphics , but from what I see I cant find a reason why I should not be using Roassal. For the time being my whole focus is to create a Vector graphics editor, as you can imagine this means a designer for vector graphics which it could create a set of classes that could find their way back to Roassal. I dont want to reinvent the wheel and I really lke to coordinate effort with people with similar goals. Let us know how we can help...

Re: [Pharo-dev] Red Box of Doom when changing the Roassal Canvas of the Easle to Athens
ok i got the moose 5 image via pharolauncher and that solves the problem. However I see when I try bezierCurve example and try to move its elements around, morphic version is at least 4 times faster while the athens version is very slow. Why is that ? You are putting your finger on one big problem of Roassal. Roassal only loosely uses Athens. For example, the bezier line is composed of many small lines. With Morphic, I suspect that drawing 1000 times 1 line is as fast as drawing 1 times 1000 lines. In Athens, triggering a drawing takes times (since you need to define a path, and I guess the drawing is done by the graphic card). So, in Athens, drawing 1000 times 1 line, as it is done now with Bezier curve, is not really efficient. However, the good news is that I have a pretty good idea on how to fix this. Currently, Roassal does too much. It should not do the rendering loop. We soon plan to add a layer between Roassal and Athens to do the rendering loop. Thanks to this layer, all the good thing of Athens will be available in Roassal. In December I will lock myself in Igor office to extract all the juice of Athens.

The first one with the square/cube I couldn’t get the camera viewpoint to move to where I could see it was a cube. That worked much better with the later examples.

[Pharo-dev] About Athens and Cairo
Hi! I have some random questions about the Cairo binding supported by Athens. - the rendering is done by the graphic card isn’t it? - Once rendered, is the produced bitmap copied by the CPU in Pharo?

Re: [Pharo-dev] About Athens and Cairo
Thanks Kilon for the explanation. Alexandre On Dec 14, 2013, at 10:56 AM, kilon alios kilon.al...@gmail.com wrote: No cairo is not GPU accelerated , rendering is done by your CPU , but of course the graphic card is the one that display things. here is a detailed explanation - http://lists.cairographics.org/archives/cairo/2012-October/023609.html please note that even in the case of opengl backend I very much disagree that this is true hardware acceleration. What the opengl backend is doing is to render cairo surfaces as opengl textures. So even though the texture themselves are hardware accelerated and will even use the the memory of the GPU the process of rendering to the texture will happen solely on the CPU. So its more like a CPU library trying to be hardware accelerated. But even using the OS backends like Quartz is not quite the same. Because you still call C code and C code is executed by your CPU and that C code suppose to call GPU functions. Opengl speed is for the very reason of shaders meaning that it compiles programs that are run solely on the gpu hence true GPU acceleration. Saying that you should not be experiencing slow downs unless you were doing something really intense. I have seen benchmarks of Cairo and they are blazing fast. Usually slow down are primarily because of bad code. I have seen animation in athens take out 50% of my dual core and others only a 5%. Cant say I am sure what happens under the surface maybe Igor may offer a more detailed look into this. I do feel however that slow speed are 99% to be blamed on Pharo way of rendering things. Something similar happens for browsers, SVG is GPU accelerated, Javascript is super fast but it only takes the slowness of DOM (HTML) itself to bring the whole system on its knees. It only take one slow part to ruin the experience. I think a solution to this would be to bypass pharo rendering completely, create a new window and render directly to that window running Pharo headless.

Re: [Pharo-dev] Similarity Matrix
The SimilarityMatrix is meant to work with one set of elements, which is the same in column and horizontal. Instead of having one class, SimilarityMatrix, we should have a framework to easily build matrixes. In your case, you simply want a matrix with a smart way of coloring. I am interesting in having such matrix. How do we proceed? Are you ready for a pair programming session these next days? I am now in Lille by the way, where are you?

Once (or even more times) we thought with Martin 2 things: 1) Reify the traversal in Fuel so that we could plug a different one. 2) Use Fuel only for traversing and allowing user a hook to plug the what to do with each node. 3) Use the same traversal of 2) for deepCopying 4) Use the same traversal of 2) to get an approximate memory consumption of the transitive closure of an object But as always happened we run out of time.

Re: [Pharo-dev] Transparent colors with NBOpenGL?
Thanks Ronie for these explanation Alexandre On Dec 26, 2013, at 7:52 AM, Ronie Salgado ronies...@gmail.com wrote: Alex, libSDL and libSDL2 are low-level multi-media libraries designed for games. Those libraries are best suited for basic pixel blitting, some lines and rect in a cross platform way. Both libraries allows you to use a custom software rendering or create a window in a cross-platform way. As for Cairo, that's a full featured vector graphics library, practically designed for SVG rendering. So, those two libraries cannot be compared, but I think that Cairo can be used to render into a texture and then use SDL to display it on screen. Actually, I don't have any experience with Cairo. As for the VM, I was looking at his Unix platform module, suspecting that the tearing and flickering was caused by using just XLib for blitting the main pharo window after Milton told that those issues aren't seen in Windows. If we add to the mix some always buggy AMD drivers, it seems that the solution goes by rewriting the display to uses OpenGL for blitting the main window, with VSync enabled, or using a separate native window for OpenGL graphics. By the way, what I found most strange about display VM code is that there's support for creating an OpenGL context already in place, with an accompanying -glxdebug flag, for verbose output. When I tried that option, I didn't get any output, so I could assume that these is not used for fast blitting under Linux. As for SDL2, it provides all the required facilities for a VM display module, without having to deal with X11 or platform specifics. Window creation, multiple OpenGL context creation, clipboard handling, input support, multi-threading, sound support, drag and drop. That version of SDL had a strong contribution by Valve, they needed something to start pushing heavily Linux, even the latest versions of Steam uses it. Anyway, I am planning to discuss this matter with Igor, during my stay at Lille. Greetings, Ronie Salgado 2013/12/26 Alexandre Bergel alexandre.ber...@me.com Ronie, You mention libSDL.

Re: [Pharo-dev] Thank you for Pharo
Hi Volkert, 2011 i gave me a push to learn Pharo and last year i decided to do a small research prototype with it. The goal is a tool to analyze and visualize application landscapes. I have implemented a small repository model for the different architecture levels, some data analytic rules on top the model, and some model visualizations. For visualization i use Roassal/Mondrian. For Data-In/-Export i use simply NeoCSV. Next year i plan to add more data analytic rules, to add model transformation operations to simulate landscape transformations (projects), and to use 3D visualizations with Roassal3D (City Metaphor). If all works fine, we see what 2015 brings … Do you have any screenshot you would like to share? Work in progress is fine. We will push Roassal 3d very very hard over the coming months. If you have some particular requests, feel free to tell us Pharo is really a productivity boost for me. If you are able to play around with the objects in an interactive environment life is getting so much easier. That is very true - Roassal3D (Roassal is so col, one of the killer frameworks for Pharo). Thanks for your nice words! Best wishes!

Re: [Pharo-dev] Glamour vs Spec (was: towards moose in the pharo ide (gtinspector / gtdebugger))
, but it can be very concise for expressing browsers. The way this works is via this component model. Essentially, a browser can be described as a set of components that can pass data to each other. Glamour lets you model that. It so happens that the inspector and the debugger are browsers and can be expressed at that level. It also so happens that most user interfaces that programmers use can be expressed as browsers, too. And Glamour was actually validated for hundreds of various browsers (literally), so it seems it can support a large set of use cases.

Re: [Pharo-dev] stroke width in Athens
to make stroke width unaffected by scale, you obviously will need to scale it down by same factor as you scaled geometry i.e.: canvas pathTransform scaleBy: factor. strokePaint width: myWidth/factor. Thanks Igor! This works like a charm. I have been intensively working with Athens for a bit more than 3 weeks. I enjoy it very very much. Thanks Igor for all this excellent work!

Roassal2 is a complete revamp of Roassal1: Athens based, faster, viva animation model, framework to build domain specific languages Roassal 3d is a complete different beast, although the idea is similar.

Re: [Pharo-dev] Roassal Visualization for control flow graph issues
Hi Clément, Thanks for your nice words. Layouts provided by Roassal are well known generic algorithm. Creating a new layout is not complicated at all. Just subclass ROLayout and override the hook methods. Creating a layout for your need is not easy. Have you tried to google for a layout? If you find one, it should be rather easy to implement it. Alexandre On Jan 14, 2014, at 12:50 PM, Clément Bera bera.clem...@gmail.com wrote: Hello Roassal developers, A few time ago Usman Bhatti showed me Roassal. Today I decided to use it for my daily work on a project that aims to optimize Pharo's methods. Firstly I am quite impressed by the quality of Roassal, I am currently using the Roassal + Mondrian builder and I have a visual representation which is very close to what I want after 1 hour of work with the help of Usman. Good job guys. Here are 2 examples of what I use: exampleIfTrueIfFalse2 | a b | a := true. a ifTrue: [ false ifTrue: [ ^ b := 1 ] ifFalse: [ b := 2 ] ] ifFalse: [ true ifTrue: [ b := 4 ] ifFalse: [ b := 5 ] ]. ^ b Screen Shot 2014-01-14 at 4.14.49 PM.png Here there's one rectangle for each basic block, entrance/exits are basic blocks with bigger borders, and borders in red represents the hot path, which the path the execution flow most frequently uses (based on native code counters added at some spots in the method by Cogit). Another example: exampleToDo 1 to: 10 do: [ :i | self kick: i ] Screen Shot 2014-01-14 at 4.36.47 PM.png Now I have a few issues with the layout. I am currently using the narrowTreeLayout which seems to be the best for my visualisation. issue 1: When branches merges, which is in a tree when a node has 2 or more parents, or when I have a #ifTrue:ifFalse:, the child is not well aligned horizontally. Here in the first visualisation I showed, BasicBlock 5 is below but not in the middle of Basic block 8,7 and 4 (horizontally). I put a minimal width for each basic block to make it better but it's still not perfect. issue 2: (most important issue) I cannot display back jumps because then all the graph is missdrawn, therefore I need to remember where they are instead of visualizing them all the time (I cannot display the back jump from basic block 3 to basic block 2 in the second representation. In addition, the back jump edge, when well displayed, overlaps the basic blocks visualizations. Here is an example of what I would like for the edges and basic block positions: Screen Shot 2014-01-14 at 4.27.32 PM.png As you can see, here exit is in the middle of B2 and B5 horizontally, which is not the case in my roassal visualization. In addition, there's a back jump from B6 to B4 that I cannot display (or all the visual representation goes nuts). The edge for the back jump does not overlap with the basic blocks. In this graph, arrows follow a grid. I don't care that arrows are diagonals instead of a mix of horizontal and vertical lines but I would like to be able to see nicely the back jumps as in this graph. Do you have an idea on what layout/view options I could use with Roassal +Mondrian to have a better result ? I tried to create my own layout but after 2 hours I understood this cost too much time for my planning (or perhaps I'm just too dumb to do it fast :-( ). Anyway, the representation I have now is good enough for me to use it. But a better one would be better, especially for back jumps :-). Thanks for any help.

When I saw the use of intrinsics in the source code, I started to suspect a bit of the alignment of some stuff and when Igor, found the segmentation fault causing instruction movdqa (Move double-quadword aligned), it was clear that it was a stack alignment issue. Checking the Intel manual confirmed this and I asked about whose responsible for aligning the stack, suspecting it was a problem with the library not conforming to the ABI. Then, Igor remembered how to change the stack alignment in native boost and it worked. This is why having people with such knowledge around is key to let us (the smart cosy smalltalkers) having fun with our cool language.

Re: [Pharo-dev] ConfigurationOfGetText broken?
What GetText is all about?
http://smalltalkhub.com/#!/~PharoExtras/Gettext does not help much

Hello,
It seems that some recent changes in the ConfigurationOfText have broken the
loading in the Pharo 3.0.
I'm loading GetText with the following script in my config.
spec
project: 'GetText'
with: [
spec
className: 'ConfigurationOfGettext';
file: 'ConfigurationOfGettext';
loads: #('Core' );
version: '1.3'; tried #development too
repository:
'http://smalltalkhub.com/mc/PharoExtras/Gettext/main'].
I get this error whatever version I put.
'The version ''1.3'' is not defined in ConfigurationOfGettext for the current
platform, because an exception occurred while creating the version:. Error:
The imported version:''1.1-baseline'' for version: 1.3 referenced from the
method: #version13: in configuration ConfigurationOfGettext has not been
defined.. Evaluate the following to see the error: ''[ConfigurationOfGettext
project ]
on: MetacelloErrorInProjectConstructionNotification
do: [:ex | ex resume: true ].''
Possible versions include: #(#bleedingEdge #development #stable
''1.0-baseline'' ''1.0'' ''1.1'' ''1.2'')'
I tried to debug and compared with the changes from the previous version but
didn't find any workable solution.

Re: [Pharo-dev] [ANN] MessageTally in GTInspector
Currently we do not have a proper support of sparklines. But this is in our roadmap.

You can simply inspect a MessageTally and you get several useful views that help you identify performance problems. You can read a more detailed description here: http://www.humane-assessment.com/blog/assessing-pharo-performance-with-gtinspector/ As an appetizer, I attached a screenshot with a Graph-ET chart (thank you Daniel Aviv for developing this engine). Very nice… using visualisation everywhere in the IDE could be extremely interesting… Does graphET already have support for Sparklines? http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0001ORtopic_id=1 This could be interesting to embed small visuals like that everywhere (not just for time related things…). Of course I have no idea for what for real… ;-) Marcus -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
