Lengthy operations block UI
by Andrei Stebakov Jan. 26, 2018

Jan. 26, 2018

I have written some code that has a deep nested loop of calling ZnClient>>get. In the loop I also execute Transcript>>show but I can only see the transcript output after a few seconds when the loop is finished. During all that time while the loop is busy the UI is also unresponsive. Is there a way to execute code in some sort of asynchronous way?

How to declare a do:[] loop for a matrix to read and acces its elements?
by Photon Jan. 26, 2018

Jan. 26, 2018

Hello folks, I am trying since yesterday to make a game of life implemenation work. It looks all ok so far but in can`t figure out the final steps. I think I get the logic I have to use and if I imagine the code in C++ for example it would be pretty much straight forward. But with pharo I got trouble telling the machine what I want. In short I`m trying to make this method work: I wrote a test wich looks like this: I want to go trough each element of the matrix(cells), check its surounding cells if they are alive, and set its counter if there are any living neighbours. It should move like this through the whole matrix to set the neighbour counter for each element. In this method i just tried the implement the topLeft check yet but I think you get the idea. You can look at the comment in the top section it shows where the neighbour indexes are. I tried so many things by now, did research read methods of the superclasses but I can`t make it work. I woud be really glad if someone gave me a little hint. What is wrong here? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

[ANN] Reed Solomon and Forward Error Correction
by henry Jan. 25, 2018

Jan. 25, 2018

I spent time straightening out Foward Error Correction, using Reed Solomon encoding with Galois Fields. I mostly have it working for some algorithms, but still have an issue with AZTEC_DATA_10, and perhaps AZTEC_DATA_12. AZTEC_PARAM, AZTEC_DATA_6 and AZTEC_DATA_10 ar working, as well as DATA_MATRIX_FIELD_256 and QR_CODE_FIELD_256. I do not know if it is pluganizable, that would be super if code split into image and plugin, naturally. I have more testing to do to get those couple of algorithms working, then I will turn to QRCode and get that working. Thank you. Here is the code... http://www.squeaksource.com/Cryptography/fec-HenryHouse.7.mcz - HH

Hi all, I just released PharoLauncher 1.1. There are now 64-bits versions for Mac and Linux. Jenkins build is now managed through a Jenkins file. Here is the changelog (details on https://github.com/pharo-project/pharo-launcher/issues) New features: #66 new command: import an image into the launcher default image folder #65 new command: remove a template from "Downloaded templates" #64 new command: create a local template from an image and remove the image #57 new option: run an image from a login shell to inherit from shell startup scripts to set up environment variables. #54 It is now possible to run an image anywhere on your file system if you click "launch" and no image is selected #23 Pharo Launcher now has an "about" box giving its description, version and a link to the bug tracker. Improvements: #62 Pharo Launcher should not load default Pharo settings #51 Pharo Launcher now sets the current directory to the directory containing the image (was the VM directory). Avoid confusions in Pharo 7 images. Bux fixes: #60 hardReset option causes troubles to PharoLauncher #56 #, was sent to nil #55 Display name of Pharo 7 images unusable #52 Cannot open a Pharo 2 image #47 Cannot run pharo 50 pre-Spur images You can get platform bundles from files.pharo.org <http://files.pharo.org/>: http://files.pharo.org/pharo-launcher/1.1/ Regards, Christophe.

Positive experience report porting from StHub to GitHub
by HernÃ¡n Morales Durand Jan. 25, 2018

Jan. 25, 2018

Hi guys, I just want to report that I started to migrate some of my projects from to GitHub (for example https://github.com/hernanmd/ApplicationSecurity and https://github.com/hernanmd/StringExtensions) in Pharo 6.x Basically the steps are: 1) Install the Peter Uhnak git-migration package: Metacello new baseline: 'GitMigration'; repository: 'github://peteruhnak/git-migration/repository'; load 2) From (GitBash) command-line: cd /c/Users/{your_git_project_directory} git log --oneline -n 1 3) Execute this script: | migration | migration := GitMigration on: '{your_sthub_user}/{project_name}'. migration cacheAllVersions. migration authors: { 'Your_Name' -> #('Your_Name' '<your_mail(a)mail.com>')}. migration fastImportCodeToDirectory: 'repository' initialCommit: '....' " copy/paste the id from the git log command in step 2)" to: 'import.txt' 4) git fast-import < /.../import.txt git reset --hard master git add * git commit -m "fast-import from SmalltalkHub" git push {project_name} or git push Let me know if there's something you would add to the workflow. Cheers, HernÃ¡n

[JOB] Engineer 1 year: Pharo IoT platform
by Marcus Denker Jan. 24, 2018

Jan. 24, 2018

Inria RMoD are looking for a full-time engineer for helping with developing Pharo in the context of IoT. The focus of this job is "Pharo on embedded and mobile devices for the internet of things" With Pharo, we have developed over the last two years an interactive, remote development environment. It allows embedded, headless software running on typical raspberry pi class hardware to be developed and debugged in an interactive way. It allows programmers to explore and change running headless embedded programs from their desktop development machine. The next step will be to extend this infrastructure to cover the use case of industrial use: Deployment. We want to build a middle-ware to manage, authenticate and script deployed Pharo embedded installations. The engineer will help to develop the Pharo IoT infrastructure, especially with a focus on industrial use: â¢ Improve Pharo for a platform with an industrial focus. â¢ Work on a middleware to manage deployed Pharo instances. â¢ Realize two small demos: First, as an industrial IoT example, a demo deployed on 20+ devices. Demo 2: Pharo deployed on multiple mobile autonomous robots. â¢ Help with creating a website for PharoIOT. We are looking for a candidate with some prior experience with Pharo. In addition: â¢ Knowledge in Dynamic Languages (Pharo is a plus but not required) â¢ Experience with embedded development is a plus but not required â¢ English Work in a research lab, but no paper writing, no teaching, no administration. In addition: â¢ Centrally located (one hour from Paris, 1h20 from London, 35 min from Brussels) â¢ Try a lot of good beer (our office is just 10km from the border to Belgium) â¢ Program with Pharo all day! â¢ Lille is an active city but not expensive (lot of students...), centrally located with good connections by train to everywhere (including CDG and Brussels airports). â¢ Duration: 12 Month â¢ Starting date: As soon as possible (Spring 2018) â¢ Salary: 2600-3200 euros brut / month, depending on experience â¢ Explanation Salary: french brutto = money after social charges (and base health insurance) before income tax, which is max one month income payed yearly, depending on family situation (can be 0 for a family with kids) â¢ Location: Lille (no remote job possible)) More about â¢ Pharo: http://www.pharo.org â¢ PharoThings: https://github.com/pharo-iot/PharoThings â¢ INRIA RMOD: http://rmod.lille.inria.fr â¢ INRIA Lille: http://www.inria.fr/lille â¢ INRIA in General: http://www.inria.fr â¢ Lille: â¢ http://en.wikipedia.org/wiki/Lille â¢ http://wikitravel.org/en/Lille Do not hesitate to contact us for more information.

Trying to test Phantom / aspects in Pharo
by Steven Costiou Jan. 23, 2018

Jan. 23, 2018

Hi, i am trying to test PHANtom but so far i can't get it to work. I found an image here https://pleiad.cl/research/software/phantom and i made it run on a vm from 2013. But the examples crashes (PhantomDemo), and i cannot make my own examples work either (simple object interception). Which vm should i use ? Is the image available in the link above still ok ? By any chance, is there a version for Pharo 6 ? Steven.
