In 2023, Varia hosted a [PrePostPrint Local Meetup](https://varia.zone/en/PrePostPrint-local-meetup.html), where a Netherlands-based group was formed. The PPP NL group is a local satellite of the wider PPP community. While free/libre open source practices seem to be more widely discussed in the context of France and Belgium, we are missing spaces for exchange and converse in the local context of The Netherlands. |
|||
|
|||
**Date:** Monday 14th October, 2024 <br> |
|||
**Time:** 19:30 - 21:30 <br> |
|||
**Entrance:** Free <br> |
|||
**Location:** Varia (Gouwstraat 3, Rotterdam) |
|||
|
|||
So, in September and October 2024, two more PPP Local Meetups will be held at Varia, within a new, experimental format. These meetups will be combined with Calm Coding, which are low-key social hangouts for those who like to write computer programs in the company of other people. For these PPP Local Meetups, there will be no set agenda. Instead, the idea is to have some informal moments to meet, hang out and spend some time together working on design and publishing experiments at Varia. As usual with Calm Coding, there will be a check-in at the beginning of the evening, and a check-out summary at the end. These meetups are free and open to the public. No registration, nor expertise is required. |

summary: Gebruikers van F/LOSS-publicatietools, verenigt u! Als je nieuwsgierig bent naar Free/Libre en Open Source Software (F/LOSS) om publicaties en lay-outs mee te maken, of als je al met deze tools hebt gewerkt en je bent op zoek naar manieren om met anderen ideeën uit te wisselen, doe dan mee! |

In 2023 organiseerde Varia een [PrePostPrint Local Meetup](https://varia.zone/en/PrePostPrint-local-meetup.html), waar een Nederlandse satteliet-groep werd gevormd. Hoewel free/libre open source-praktijken breder besproken lijken te worden in de context van Frankrijk en België, missen we ruimte voor uitwisseling en conversatie in de lokale, Nederlandse context. |
|||
|
|||
Daarom vinden er in september en oktober 2024 nog twee PPP Local Meetups plaats bij Varia, binnen een nieuw, experimenteel format. Deze bijeenkomsten worden gecombineerd met Calm Coding, rustige sociale bijeenkomsten voor degenen die graag computerprogramma's schrijven in het gezelschap van andere mensen. Voor deze PPP Local Meetups is er geen vaste agenda. In plaats daarvan is het de bedoeling om informele momenten te hebben om elkaar te ontmoeten, rond te hangen en wat tijd samen door te brengen bij het ontwerpen en publiceren van experimenten bij Varia. Zoals gebruikelijk bij Calm Coding is er aan het begin van de avond een check-in en aan het einde een uitcheckoverzicht. Deze bijeenkomsten zijn gratis en openbaar. Registratie, noch expertise is vereist. |

.Synopsis |
|||
Activate a Python virtual environment for the current PowerShell session. |
|||
|
|||
.Description |
|||
Pushes the python executable for a virtual environment to the front of the |
|||
$Env:PATH environment variable and sets the prompt to signify that you are |
|||
in a Python virtual environment. Makes use of the command line switches as |
|||
well as the `pyvenv.cfg` file values present in the virtual environment. |
|||
|
|||
.Parameter VenvDir |
|||
Path to the directory that contains the virtual environment to activate. The |
|||
default value for this is the parent of the directory that the Activate.ps1 |
|||
script is located within. |
|||
|
|||
.Parameter Prompt |
|||
The prompt prefix to display when this virtual environment is activated. By |
|||
default, this prompt is the name of the virtual environment folder (VenvDir) |
|||
surrounded by parentheses and followed by a single space (ie. '(.venv) '). |
|||
|
|||
.Example |
|||
Activate.ps1 |
|||
Activates the Python virtual environment that contains the Activate.ps1 script. |
|||
|
|||
.Example |
|||
Activate.ps1 -Verbose |
|||
Activates the Python virtual environment that contains the Activate.ps1 script, |
|||
and shows extra information about the activation as it executes. |
|||
|
|||
.Example |
|||
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv |
|||
Activates the Python virtual environment located in the specified location. |
|||
|
|||
.Example |
|||
Activate.ps1 -Prompt "MyPython" |
|||
Activates the Python virtual environment that contains the Activate.ps1 script, |
|||
and prefixes the current prompt with the specified string (surrounded in |
|||
parentheses) while the virtual environment is active. |
|||
|
|||
.Notes |
|||
On Windows, it may be required to enable this Activate.ps1 script by setting the |
|||
execution policy for the user. You can do this by issuing the following PowerShell |
|||
command: |
|||
|
|||
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser |
|||
|
|||

.Synopsis |
|||
Remove all shell session elements added by the Activate script, including the |

addition of the virtual environment's Python executable from the beginning of |

session. |

.Description |
|||
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the |
|||
given folder, and returns them in a map. |
|||
|
|||
For each line in the pyvenv.cfg file, if that line can be parsed into exactly |
|||
two strings separated by `=` (with any amount of whitespace surrounding the =) |
|||
then it is considered a `key = value` line. The left hand string is the key, |
|||
the right hand is the value. |
|||
|
|||
If the value starts with a `'` or a `"` then the first and last character is |
|||
stripped from the value before being captured. |
|||

pip - The Python Package Installer |
|||
================================== |
|||
|
|||
.. image:: https://img.shields.io/pypi/v/pip.svg |

:target: https://pypi.org/project/pip/ |

|||
:target: https://pip.pypa.io/en/latest |
|||
|
|||
pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes. |
|||
|
|||
Please take a look at our documentation for how to install and use pip: |
|||
|
|||
* `Installation`_ |
|||
* `Usage`_ |
|||
|
|||
We release updates regularly, with a new version every 3 months. Find more details in our documentation: |
|||
|
|||
* `Release notes`_ |
|||
* `Release process`_ |
|||
|
|||
In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right. |
|||
|
|||
**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3. |
|||
|
|||
If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms: |
|||
|
|||
* `Issue tracking`_ |
|||
* `Discourse channel`_ |
|||
* `User IRC`_ |
|||
|
|||
If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms: |
|||
|
|||
* `GitHub page`_ |
|||
* `Development documentation`_ |
|||
* `Development IRC`_ |

This is used in the resolver to check whether two URL-specified requirements |

(e.g. "a=1&b=2" vs "b=2&a=1") and produce conflicts unexpecting to users. |

Currently this does three things: |

1. Drop the basic auth part. This is technically wrong since a server can |

serve different content based on auth, but if it does that, it is even |

impossible to guarantee two URLs without auth are equivalent, since |
|||
the user can input different auth information when prompted. So the |
|||
practical solution is to assume the auth doesn't affect the response. |
|||
2. Parse the query to avoid the ordering issue. Note that ordering under the |
|||
same key in the query are NOT cleaned; i.e. "a=1&a=2" and "a=2&a=1" are |
|||
still considered different. |
|||
3. Explicitly drop most of the fragment part, except ``subdirectory=`` and |
|||
hash values, since it should have no impact the downloaded content. Note |
|||
that this drops the "egg=" part historically used to denote the requested |

conflicts, so we choose to also ignore them. |
