What needs to be done is to come up with a reviewed, reproducible, easy to use installation process. The steps I used are a) a fresh new Ubuntu 18.04.1 64 bit bionic beaver installation then sudo apt-get update b) python --version Command 'python' not found, but can be installed with: python3 --version Python 3.6.5 b) Instead of anaconda I tried then pip3 approach sudo apt install python3-pip python3 -m pip install jupyter But jupyter notebook did not work. After sudo apt install jupyter-core sudo apt install jupyter-notebook This only downloaded 50MB instead of the 600MB for anaconda The command jupyter-notebook worked. Note the dash, i.e. it is a different command Then sudo apt-get install curl and the Pharo 6.1 64 bit installation curl get.pharo.org/64/61+vm | bash Then the Metacello installation taken from https://github.com/jmari/JupyterTalk. Creation of the kernel.json file as described in https://github.com/jmari/JupyterTalk was not necessary The content of ls /usr/share/jupyter/kernels/ is only python3 Interestingly, no entry for a Pharo kernel. The CLI command jupyter-notebook brings up a working Jupyter dashboard with the Pharo Smalltalk menu entry installed in the 'New' menu. --Hannes On 8/24/18, H.

Re: [Pharo-users] How do I get ZeroMQ working?

by Jesus Mari Aguirre

I see...anaconda installs everything in home directory. ZeroMQ version won't be a problem, probably it is backward compatible. I will include $home/anaconda3/lib in the searching path.

Re: [Pharo-users] How do I get ZeroMQ working?

by H. Hirzel

Thinking about it again: Going for a Python - anaconda distribution related hack is to specific. I am rather interested in a regular ZeroMQ installation for Pharo. I have now created a new Ubuntu 18.04.1 bionic beaver installation and the question is: how do I set ZeroMQ up togehter with Pharo (Juyptertalk) On 8/24/18, H.

Re: [Pharo-users] Dynabook and authentic learning pedagogy

by H. Hirzel

Hello Hilaire Thank you for the short summary what authentic learning is and the conclusions what this means for a Dynabook implementation. You conclude that Dynabook's tools should support using authentic documents. I think that in practice this means that DOCX and ODT documents should be supported in some way. The Dynabook tools should generate DOCX/ODT documents and also read them. [1] The cnx repository (https://cnx.org/) for learning materials allows the author to use DOCX/ODT documents to upload content. There is the requirement that a particular style sheet is used. [2] For Dr. Geo it will probably mean that it can read and write DOCX/ODT documents which follow some conventions. The same might also apply for HTML. I am also doing investigations in JSON based Jupyter notebooks as you can see in another thread. That might be an easier option though only 'authentic' for a more limited though large audience. --Hannes [1] DOCX - the main file format used by Microsoft Word. ODT for LibreOffice. Compatibility is OK if you go for a subset of commonly supported functions. More than sufficient for Dynabook. LibreOffice 6.1 now supports easy production of epub books. [2] Mainly requiring the built in titles styles to be used and then there is a style for code. With this you can achieve a lot.

Re: [Pharo-users] Pharo 6 snap package

by H. Hirzel

Hello Alistair Thank you for the detailed answer. I understand that at the moment going for a Pharo snap package does not seem to be useful. In particular as a Pharo installation may reside in a directory with everything included. So different Pharo installations may reside in different directories. I think where snap still might come is for solutions which require more than a particular Pharo installation. For example I could think of combining a particular Pharo version with a particular Jupyter notebook installation into a snap which could lead to a web based 'Dynabook' solution. I am also looking forward to Guille's answer. Regards Hannes On 8/23/18, Alistair Grant <akgrant0710(a)gmail.com> wrote: > Hi Hannes, > > On Wed, 22 Aug 2018 at 17:20, H.

Re: [Pharo-users] How do I get ZeroMQ working?

by H. Hirzel

Thank you, JesÃºs MarÃ. I reloaded your updated JupyterTalk Pharo Smalltalk package which now looks for more places to find the library ZeroMQ. Unfortunately it still did not find the ZeroMQ library. The following command shows where there is a ZeroMQ library: [1] root@Latitude2:/# find / -name libzmq*.so.* /home/user25/anaconda3/lib/libzmq.so.5 /home/user25/anaconda3/lib/libzmq.so.5.1.5 /home/user25/anaconda3/pkgs/zeromq-4.2.5-h439df22_0/lib/libzmq.so.5 /home/user25/anaconda3/pkgs/zeromq-4.2.5-h439df22_0/lib/libzmq.so.5.1.5 ------ So there is libzmq.so.5 and not libzmq.so.3 which you need for JuypterTalk. So I need to install either libzmq.so.3 library separately or JupyterTalk needs to be changed to also look for libzmq.so.3, libzmq.so.4 or libzmq.so.5 I'll look into your code and try a hack to look for /home/user25/anaconda3/lib/libzmq.so.5 --Hannes ------------------------------------------------------------------------------------------------------------------ [1] Context: ZeroMQ was installed by the Python Anaconda distribution. I t is the recommended way for installing the JupyterNotebook http://jupyter.org/install The idea is that you get everything in one big installation ('a distribution') However it seems that going for opteion 2 (pip installation seems to be easier next time). But as I have a working Jupyter installation now it is left with getting a ZeroMQ installation which JupyterTalk finds.

I've been playing with nteract and surprissently it uses the same kernels than Jupyter, it means all of your kernels published in /use/local/share/jupyter/kernels are usable by nteract.
