Changes (by annakrat):

 * status:  new => closed
 * resolution:   => fixed


Comment:

 There has been many more fixes for wxPython 4 in 7.8, so I would recommend
 switching to that.

[GRASS-dev] Presentation at Geospatial Devroom at FOSDEM 2020: Sunday 2 Feb in Brussels

2020-01-31 Thread Markus Neteler 
Hi all,

Quick reminder about the upcoming Geospatial Devroom at FOSDEM 2020 in
Brussels this weekend.
"The Geospatial devroom is the place to talk about the state of the
art of open, geo-related data, free and open source geospatial
software and its ecosystem. This includes standards and tools, e.g.
spatial databases, online mapping tools, geospatial services, used for
collecting, storing, delivering, analysing, and visualizing geodata."

The full schedule: https://fosdem.org/2020/schedule/track/geospatial/

Important: FOSDEM is free to attend. There is no registration. Just turn up!

FOSDEM takes place at the ULB Solbosch Campus in Brussels, Belgium:
https://fosdem.org/2020/practical/

See you there!

Markus

PS: I'll present "actinia: geoprocessing in the cloud":

[GRASS-dev] Fwd: [OSGeo-Discuss] Reminder GSoC 2020 - Call for ideas and mentors

Please consider this, mentors and ideas wanted!

Dear OSGeo community,

It is time for *GSoC* [1] this year, so this is our starting
information to get involved!

If you are willing to act as a mentor [2], fill in this form:

< https://forms.gle/LACjb4x2DTCHvngK6 >

If you want to participate proposing ideas, you just need
to send us (admins:  ) the URL for your project's
ideas page.

Remember that every idea should indicate:

• A title
• A description
• 2 mentors
• A test for the students to submit to your evaluation. The test
aims at evaluating if the student is capable for the project, so
please design the test having in mind the skills required to complete
the project.

Time is short, we need to collect all URLs by Feb 3. After that date,
Google's admins will start evaluating the organisations based on the
submitted ideas pages and decide which orgs will be accepted for this
edition.

Thanks for your cooperation!

Kind regards
OSGeo GSoC admins
