Re: [Qgis-user] Announce - migrate our mailing lists to Discourse

[David Strip via QGIS-User]

  
  
I've never used Discourse so I'm not in a position to compare it's
usefulness to the existing email format. I can add one more voice
expressing satisfaction with the email approach and how it
encourages readers to view everything rather than narrowing focus to
topics of interest. It also strikes me that we will inevitably lose
some people in the transition because of the friction required to
move focus to a new format, regardless of whether you like or hate
Discourse.

[Michael Shand via QGIS-User]

Another great mapping list bites the dust.
I used CartoSOC for over 20 years which was great for info and connecting with 
like minded cartographers, after a merger it became a Forum and died a slow 
death.

Régis and everyone else,

My apologies; I try not to top post but my response is more an overall reaction 
to your announcement rather than a point by point response.

I was a member (??) over at opensource.com's Discourse 
instance until RedHat decided to shut down support for 
opensource.com, so I have some experience with that 
Discourse configuration, also plenty of experience with mailing lists.  Also 
familiarity with the Ubuntu Forums, Stack Exchange etc.

In my experience, Discourse "out of the box" doesn't offer any net benefit to 
its users.

It's quite possible that people interested in, and willing to invest time and 
effort into customizing their usage profile would benefit more from Discourse 
than from a mailing list.  I have no experience with that.

You may be correct when you say that we will attract more new users by offering 
them Discourse than by maintaining a mailing list.  I guess the question that 
begs to be asked is, will those new users thereby turn into contributors, or 
will the biggest Discourse channel be "how do I install QGIS on my new Mac"?

I suppose, perhaps wrongly, that most of us on this (and other) mailing lists 
are here because the list provides a sense of community, an opportunity to pay 
back by offering a bit of help, an opportunity to stumble on something new and 
useful from time to time... what else?  I'm pretty sure none of us participate 
in this list to learn how to participate effectively in lists.  Moreover, we 
don't really have the tools to "only pay attention to topics X, Y and Z".  So 
all of us get to see the beginner questions, and the responses, and sometimes 
we find ourselves in the situation of starting fresh with something that, 
because of this broad familiarity, is not a total blank.

In contrast, in my experience, moving to Discourse, or any other similar 
forum-type structure, allows or even encourages us to stick to certain topics 
that we think may be of interest and avoid all others.

I would argue that we thereby cheapen and diminish our contribution back to the 
forum, simply because we miss real opportunities to help while we avoid reading 
certain topics; and by doing so, we reduce the sense of community we get by 
belonging to the list.  I would further argue that we run the risk of not 
learning many new things because by streaming topics into tens or hundreds of 
specialist channels, we inevitably miss things that might benefit us.

Finally, we have the "opportunity" to spend more of our limited time learning 
about configuring our participation in this mechanism, rather than just 
participating.  Your example of learning how to treat Discourse like a mailing 
list by following the Mozilla tutorial addresses this situation precisely - 
instead of helping a person with their configuration issues, or learning more 
about how to structure the queries used in QGIS, we are tweaking the Discourse 
knobs and levers to get the "optimum" experience.

I guess you can tell that I'm negative on this concept.  I don't feel that the 
mailing list is a be-all and end-all.  But I am pretty sure, again based on my 
experience, that the lovely community we have here on 
qgis-user@lists.osgeo.org will not be the 
same collection of good things once migrated to Discourse.  I do hope that I am 
wrong!

Re: [Qgis-user] Moving many project files - bulk updating paths to tables?

[Tony Shepherd (FarmMaps NZ) via QGIS-User]

Thanks Jorge

 

Yes, I toyed with that, but somewhat painful with thousands to process.

 

Has anybody scripted or coded something for this?

Hi Tony,

You can unzip the qgz file and change the text in the qgs files. qgs are text 
files. Afterwards, you can create the zip again with the qgz extension or open 
the qgs file directly.

I hope it helps,

Essentially, I am shifting my entire collection of GIS work to a shared

In my old MapInfo days, I would simply do a bulk search and replace over the 
workspace files (text-based so this is easy) and change the paths that need 
changing and all would be ok.

 

As qgz files are not easily modified through a text editor, are there any tools 
out there to enable bulk changing of file paths in those files? 

 

Any other approaches?

If you use Python it should be fairly simple to enumerate all layers, test to 
see if they're file based and then use pattern matching to alter the file paths

Re: [Qgis-user] Announce - migrate our mailing lists to Discourse

[chris hermansen via QGIS-User]

Régis and everyone else,

My apologies; I try not to top post but my response is more an overall
reaction to your announcement rather than a point by point response.

I was a member (??) over at opensource.com's Discourse instance until
RedHat decided to shut down support for opensource.com, so I have some
experience with that Discourse configuration, also plenty of experience
with mailing lists.  Also familiarity with the Ubuntu Forums, Stack
Exchange etc.

In my experience, Discourse "out of the box" doesn't offer any net benefit
to its users.

It's quite possible that people interested in, and willing to invest time
and effort into customizing their usage profile would benefit more from
Discourse than from a mailing list.  I have no experience with that.

You may be correct when you say that we will attract more new users by
offering them Discourse than by maintaining a mailing list.  I guess the
question that begs to be asked is, will those new users thereby turn into
contributors, or will the biggest Discourse channel be "how do I install
QGIS on my new Mac"?

I suppose, perhaps wrongly, that most of us on this (and other) mailing
lists are here because the list provides a sense of community, an
opportunity to pay back by offering a bit of help, an opportunity to
stumble on something new and useful from time to time... what else?  I'm
pretty sure none of us participate in this list to learn how to participate
effectively in lists.  Moreover, we don't really have the tools to "only

[Qgis-user] Calculate intersecting area of two layers in a virtual field. Context of @geometry in overlay_intersects()

[Klaus Affeldt via QGIS-User]

Hello Bruno,

try it the other way around:

coalesce(
  area(
intersection(
  @geometry, 
  collect_geometries(
overlay_intersects(
  'forest',
  @geometry
)
  )
)
  ),
  0
)

In addition you can use the inner part in the geometry generator.
So you have a visual help to compare your results:

intersection(
  @geometry, 
  collect_geometries(
overlay_intersects(
  'forest',
  @geometry
)
  )
)

[Qgis-user] Plugin using Pythonnet fails to start during installation

[Lars I. Nielsen via QGIS-User]

Hi all.

We've developed a QGIS plugin, that utilizes Pythonnet to communicate with C# 
on Windows.

Pythonnet is not part of the chosen distribution for Python in QGIS (as of 
3.34), so we do a separate installation of this module into %APPDATA%/Python, 
which is used by all Python distributions on the PC.

But even after Pythonnet has been installed correctly, we get an error when the 
QGIS plugin installer tries to start the plugin.

However, the plugin has been installed correctly, and it starts just fine when 
one manually activates it in the plugin window list.


Why can't the plugin start when activated by the QGIS plugin installer ?
Is it running in some kind of restricted environment, that excludes use of the 
APPDATA location ?

Cheers.


Ps!
Yes, we are aware of different versions of Pythonnet in Python 3.7 vs 3.9. We 
install both.

Re: [Qgis-user] Announce - migrate our mailing lists to Discourse

[Tony Bazeley via QGIS-User]

Hi Régis,

It seems the "end of life" refers to the Mailman 2, and there's no desire to 
migrate to 
Mailman3, which in my view is a pity as the archives[1] at least look like a 
nice piece of 
work.

I'm currently considering migrating a small list from mailman2 to mailman3 and 
wonder 
if you would mind explaining a little further those "not conclusive" tests.

Can you advise when it's proposed to close the qgis-user list?

And what will happen to the archives which to my mind represent the collective 
work of 
many contributors and a valuable piece of knowledge? 

Thanks
Tony

[Qgis-user] restrict QGIS user interface (project & layer properties and other dialogs)

[Felix Deutsch via QGIS-User]

Hi,

using 3.34.5 LTR version.

I want to lock down QGIS user interface as much as possible (for the casual 
user, I know that a determined user will always be able to reset settings).
In addition to using UI Customization (and then disabling this menu entry), I 
managed to customize context menus like in the LayerTree by implementing a 
custom QgsLayerTreeViewMenuProvider via startup.py.

What is missing is locking down project & layer properties, the latter of which 
is still reachable via doubleclick on the layer tree and also via hotkey. How 
can I accomplish this?

I first thought that disabling those widgets in the screenshot below would do 
the trick, but no.

[Qgis-user] Calculate intersecting area of two layers in a virtual field. Context of @geometry in overlay_intersects()

[Bruno Streit via QGIS-User]

Dear list

Great, how powerful expressions are in QGIS!
I have two polygon layers, one with parcels and one with forests. In a virtual 
field of the layer parcels I'm trying to calculate the area covered with 
forest. I can sum the area of intersecting forests in a virtual field with the 
follwing expression:

coalesce( 
  array_sum( 
overlay_intersects(
  layer:= 'forest', 
  expression:= area(@geometry)
)
  )
, 0)

But @geometry doesen't return the intersecting area. It returns the whole 
polygons, that partly intersect the parcel. So I could add an additional 
intersection():

coalesce( 
  array_sum( 
overlay_intersects(
  layer:= 'forest', 
  expression:= area(
intersection(
  @geometry, geometry(get_feature_by_id()
)
  )
)
  )
, 0)

@geometry is calculated in the context of the layer forests. How could I access 
the geometry of the parcel inside of overlay_intersects()? get_feature_by_id() 
doesn't seem to help, since I don't see a way to get the actual ID of the 
parcel. 
It is not possible to return @geometry as expression in overlay_intersects and 
do the intersection outside.

Does any one have an idea, how I could get the intersected area?
Thank you. Bruno

Re: [Qgis-user] 1. Announce - migrate our mailing lists to Discourse (R?gis Haubourg)

[Régis Haubourg via QGIS-User]

Thanks for your feedback Raúl !

At this stage, just spreading the word of creating an account in 
discourse.osgeo.org via LDAP OSGEO should be enough. There is already a 
bunch of interesting to follow there.


Cheers

Re: [Qgis-user] Announce - migrate our mailing lists to Discourse

[Régis Haubourg via QGIS-User]

Hi Tony,

we know about mailman3 rewrite. from the tests of SAC and other 
projects, it was not conclusive.


About keeping both system, this is the best way to fragment a bit more 
our community, which already is dispersed through too many channels. 
This is the problem we want to fix here.   This is a hard requirement in 
this move, ie stay DRY.


Gnome, Mozilla and Ubuntu are all fighting against the same issue. We 
try to clarify which should be the official channels, and still want to 
offer communication means that are really used. From my perspective, I 
use Discourse mainly by mail, and have the additionnal possibility of 
using the web UI to write markdown , add images and color syntaxed code. 
I woud not see the benefit of having to "also" keep monitoring other 
mailing lists.



Cheers

Re: [Qgis-user] Announce - migrate our mailing lists to Discourse

[Julien Moura (Oslandia) via QGIS-User]

Hi Régis and PSC,

Great news and exciting evolution for QGIS community! Thanks for the 
underlying work along with the OSGeo tech team.


On my side, I think it's a good evolution to make the project more 
reachable for classic end-users and an honest trade-off for long-live 
dev/tech users since Discourse can behave as a a mailing list too.


I hope that will help to reduce QGIS communication channels and look 
forward to see every related event and discussions live on Discourse.


Regards,
Julien

Hi Greg,
Of course you are free to react !
I'm interested in understanding why you feel this would reduce 
engagement.
I've been testing Discourse a lot in the past years. From french 
spaces around open data and numeric commons, to a first test with QGIS 
french user lists.

What I have observed is :
- new users jump in more easily than with our obscure mailing list habits.
- I just don't see any usage difference once I changed my settings 
from the default digest setting to "one mail per interaction"
- it is a lot easier to subscribe to a category than to subscribe in 
mailman to a new mailing list.
- finding topics via search engine is so much more normal. Remember we 
needed Nabble to offer this and it was not an easy experience. And 
Nabble died.
- as a list administror, mailman backoffice interface does not make it 
easy. It has been designed in the early stages of the web. This is so 
hard to understand, read and maintain. And don't try on a phone.


On the downsides, I just had to explore notification settings and 
understand how categories work a bit more than I would have expected. 
But a lot less time than the numerous hours struggling with mailman 
admin interfaces.


So if you have tangible ideas or facts we are really interested.  
Discourse is open source and really full of features, settings or 
plugins to tune it to our needs.


Cheers
Régis

I'm unhappy about this, as I suspect are others who have been in the
Free Software world a long time.  I expect that this will lead to
reduced engagement by the longer-term-FS people.  Part of this is that
tools that encourage post-and-only-see-answers lead to a help desk
feeling that than a community.

I don't expect to be listened to in any serious way, but you said
"feel
