h2. Discussion results
152 129 Denis 'GNUtoo' Carikli
153 158 Denis 'GNUtoo' Carikli
h3.  Do we care about supporting devices with non-removable batteries? 
154
155
Points that were mentioned or discussed:
156
* This impacts the design decisions as supporting new devices through upstream code takes longer than hacking together the vendor code not to require nonfree libraries.
157
158
* Because of that either users, repair shops or Replicant device vendors will need to have a viable way to change the non-removable battery.
159
160
* If this is not the case it would force the Replicant project to race to try to support a device while it's still being sold new. If not users buying devices would have a battery that doesn't last enough when bought second hand.
161
162
* It's too hard, even for vendors like Technoethical which have some expertise in that area to upgrade non-removable batteries when the case is sealed. Practically speaking that could be done but the end result would not be as good as the new device, like the sealing would not be as good, making users damage the phone as they would expect the sealing to work.
163
164 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
165
* The cost for Replicant would be too high, so participant thought that not caring about devices without non-removable batteries and prioritize to support devices in Replicant through upstream project was better
166 158 Denis 'GNUtoo' Carikli
167 160 Denis 'GNUtoo' Carikli
h3. Do we require free software bootloaders ?
168 158 Denis 'GNUtoo' Carikli
169
Points that were mentioned or discussed:
170
* The Pinephone should be released in the next months (3 months?) but it's not released yet.
171 1 Denis 'GNUtoo' Carikli
* Some other devices with free software bootloaders are not released yet either
172
* Some concerns were raised on the fact that the Librem5 bootloader might contain nonfree software, which Replicant doesn't want to redistribute. A link to "Purism's plans":https://puri.sm/posts/librem5-solving-the-first-fsf-ryf-hurdle/ was also mentioned. Paul also mentioned that it might be possible that replacing the nonfree part was doable and that it would solve the issue
173
174 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
175
* Too early to do that: Replicant 9 is not out yet and it will work on devices with nonfree bootloader at first, but the work could be reused later by devices with free software bootloaders
176 160 Denis 'GNUtoo' Carikli
177
h3. Do we require isolated modems ?
178
179
Points that were mentioned or discussed:
180
* On one hand it would make it easier for users to understand the freedom privacy and security they are getting with Replicant. The information is often distorted up to the point where some users think that Puri.sm laptops are running only free software (while in reality there are non-free software involved in the boot such as the FSP, and a minimal Management Engine firmware). 
181
* On the other hand some users might already have devices that were supported by Replicant before and that don't have an isolated modem. This would leave such users with old versions of Replicant.
182
183
Consensus in that meeting:
184
* The devices with non-isolated modems might not be easy to support in Replicant 9 anyway, so we could drop them
185
* This will need to be announced for the Replicant 9 release as this way the information would propagate more efficiently to people.
186 158 Denis 'GNUtoo' Carikli
187
h3. How to handle the various keys used to sign releases, and other related things and should the recovery check signatures 
188
189
Points that were mentioned or discussed:
190
* The installation instructions need to be as simple as possible => If users have to check the signatures only once it's better. So now users check the recovery only, which then checks the rest.
191 1 Denis 'GNUtoo' Carikli
* The people involved in local Replicant install parties (in Paris) will help local Replicant users to update the recovery
192 158 Denis 'GNUtoo' Carikli
* Technoethical previously stated that the users having bought devices already running Replicant through them are either able to install new recoveries or that they are able to help them do it 
193
194
Consensus in that meeting:
195
* Keys usage in the short term: Developers sign with their keys
196 1 Denis 'GNUtoo' Carikli
* Keys usage in the longer term (requires time to implement it): use a keyring with the public key of several Replicant developers, like it is done in Parabola with the parabola-keyring package 
197 158 Denis 'GNUtoo' Carikli
* Keep checking signatures by default in the recovery
198
199
h3. Improve information for current and potential Replicant users
200
201
Points that were mentioned or discussed:
202
* Fil Bergamo plans to work on an unified table that has various information on devices supported by Replicant:
203 1 Denis 'GNUtoo' Carikli
* He plans to add in information about what hardware feature are supported or not
204 178 dl lud
* He plans to add information about how likely are the devices to be supported in the next Replicant 6 and 9 releases
205 158 Denis 'GNUtoo' Carikli
* A "device getting guide" was also mentioned, to help users find which supported devices are the best for them
206
207
h3. Improving the Replicant website
208
209 1 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
210 161 Denis 'GNUtoo' Carikli
* It would be nice to make information for users more accessible on the main page (https://replicant.us)
211 1 Denis 'GNUtoo' Carikli
212 159 Denis 'GNUtoo' Carikli
Consensus in that meeting:
213
* Also enable translations in other languages than English in the wiki, but warn readers that the information might be outdated when it's translated.
214
215 1 Denis 'GNUtoo' Carikli
h3. Making it easier for anyone to contribute to Replicant
216
217 159 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
218
* A question was raised about making a welcome page for new Replicant contributors. That page is supposed to already exist in the wiki => Find it and look at it.
219
220
Consensus in that meeting:
221
* Create working groups on various part of Replicant (such as the documentation, f-droid issues, etc) and split the Redmine instance in sub-project accordingly. It would also enable to have different settings for the subgroups.
222
* Modify the [[People]] page to enable any contributor or potential contributors to add themselves in that page with the topic they would want to work on and the skills they have. The Replicant front page (https://replicant.us) would be modified to make sure that this is visible to potential contributors.
223
* Add pointers to C courses and to where to get the skills required to contribute to the Replicant system source code.
224
* Try to find a way to make a *simple* presentation on Replicant, that would give a simple overview how how Replicant and the hardware works.
225 158 Denis 'GNUtoo' Carikli
226
h3. Funding work on f-droid
227
228 163 Denis 'GNUtoo' Carikli
Consensus in that meeting:
229
* Enabling Fil Bergamo to work on making F-Droid FSDG compliant through NlNet funding
230 1 Denis 'GNUtoo' Carikli
231 163 Denis 'GNUtoo' Carikli
h3. Using oFono RIL
232 1 Denis 'GNUtoo' Carikli
233 163 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
234
* Enabling Fil Bergamo to work on making that through NlNet funding
235
236
Consensus in that meeting:
237
* Using oFono RIL is a good idea, even if it's unmaintained. Replicant would then become its maintainer
238 158 Denis 'GNUtoo' Carikli
239
h3. FSDG compliance and How to moderate the forums 
240
241
Points that were mentioned or discussed:
242
* One of the main issue was the fact that people might have legitimate interest in linking to post from XDA which would contain both very valuable technical information, while not respecting the FSDG guidelines at all and pushing users to run nonfree software.
243
* Legal issues were raised as well when linking to external material and such.
244
* Some examples were given on how to handle some common issues:
245
** Link to a book chapter advocating for DRM on the FSF website:
246 124 Denis 'GNUtoo' Carikli
  *URL:* https://www.fsf.org/blogs/sysadmin/the-management-engine-an-attack-on-computer-users-freedom
247
  <pre>
248
  For more information about Digital Restrictions Management and the Management Engine,
249
  see from page 191 [...].
250
  This chapter tries to justify the usage of Digital Restrictions Management (DRM).
251 1 Denis 'GNUtoo' Carikli
  DRM is totally unacceptable as it requires the users not to be in control of their
252 124 Denis 'GNUtoo' Carikli
  computers to effectively prevent them from exercising their legal rights (such as fair
253
  use, or being able to copy published works). That chapter clearly shows the link between
254
  preventing users from controlling their hardware and effective DRM.

  The following analysis was conducted using the libsec-ril.so binary file
269
   (the incriminated proprietary software) as extracted from the CyanogenMod 10.1.3
270
   system zip for the Galaxy S 3 (I9300), from location system/lib/libsec-ril.so.

People in this discussion realized that the forum is relatively small so it's doable to have it moderated.
287 158 Denis 'GNUtoo' Carikli
288 1 Denis 'GNUtoo' Carikli
Plan of action:
289 158 Denis 'GNUtoo' Carikli
* Describe what should is acceptable or not for the forums, wiki, etc
290
** "Please do not distribute, recommend, or support non-free software here"
291
** Also describe the above examples there if possible to help people linking to information in the right way.
292
* How to handle violations of the policy
293
** On case by case basis. Help educate people on the matter and how to deal with it, especially on how to link to external information. |

h3. Do we ship some external applications in Replicant
297
298
Points that were mentioned or discussed:
299
* Yes, but how does the selection process would look like?
300 152 Denis 'GNUtoo' Carikli
* Which browser we should add => One that works and that doesn't have freedom privacy or security issues 
301 158 Denis 'GNUtoo' Carikli
* Firefox Lite was mentioned but it was dismissed due to very concerning privacy issues with its privacy policy
302
303
h3. Using wayland for the graphic stack?
304 1 Denis 'GNUtoo' Carikli
305 164 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
306
* Using "wayland":https://www.collabora.com/news-and-blog/blog/2019/04/01/running-android-next-to-wayland/ for the graphics backend
307
* Might loose some performance due to the fact that Wayland plug in Android too low in the stack
308
* No performances test were performed with Wayland.

h3. AOSP vs LineageOS
311
312
Points that were mentioned or discussed:
313
* Using LineageOS repos makes less sense due to consensus about supporting devices with removable batteries.
314 111 Denis 'GNUtoo' Carikli
* AOSP has stable/tagged releases whereas LineageOS lacks that 
315 147 Denis 'GNUtoo' Carikli
* AOSP is also better documented
316 113 Denis 'GNUtoo' Carikli
Since:
317 117 Denis 'GNUtoo' Carikli
* LineageOS uses many repositories from AOSP already (Implicit at the time of the talk, not explicited)
318 1 Denis 'GNUtoo' Carikli
* we still want some of the features from LineageOS (like root)
319
We will need to look into more details which repositories to use from LineageOS and from AOSP 
320 158 Denis 'GNUtoo' Carikli
321 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
322
* Getting closer to AOSP
323 117 Denis 'GNUtoo' Carikli
324 165 Denis 'GNUtoo' Carikli
h3. Android upstream vs GNU/Linux upstream
325
326
Consensus in that meeting:
327
* Getting closer to GNU/Linux upstream (for hardware support like modems, etc)

h2. Video encoding
331 113 Denis 'GNUtoo' Carikli
332
h3. Sound
333
334
The microphone was mono, with only a channel from the left. So we need to create mono audio files from the videos.
335
336
To make the sound go in both channel, do the following in Audacity:
337
338
* Create a new project with File -> New
339
* Import the video file with File -> Open
340
* Click on the audio channel -> Split Stereo to Mono
341
* Delete the second channel
342
* File -> Export -> Export as WAV
343
344 114 Denis 'GNUtoo' Carikli
h3. Video 
345
346
The videos were recorded with some equipement that was lent to us:
347
* A camera that outputed mp4 files on an SD card
348
* One wireless microphone
349
350
=> Next time ask if they have a second microphone available for questions.
351
352
* The videos are splitted in several mp4 files
353 115 Denis 'GNUtoo' Carikli
* The part before the presentation has to be removed
354
355
Kdenlive is being used for that.
356
357
Using kdenlive with Nouveau (with default settings), xfce4 under Parabola manage to freeze the screen (there are some messages like "nouveau: kernel rejected pushbuf: Cannot allocate memory" that can be observed when launching kdenlive through SSH).
358
359 116 Denis 'GNUtoo' Carikli
To workaround that the following was used:
360
* gnome3 (probably under wayland)
361 1 Denis 'GNUtoo' Carikli
* pushbuffer enabled in the module parameters for nouveau
362
363
=> It's still slow while zomming in the timeline but it manage not to freeze the whole graphics stack.
364
365
To edit a video with kdenlive:
366
* create a project, and select the right resolution (720p 25fps here)
367
* Import the videos files to use with project->Add clip
368
* Also import the mono audio files that you just converted with audacious
369
* Import the clips from the Project bin into the timeline with drag and drop
370
* Right click on the imported click in the timeline and select Ungroup
371
* Right click on the audio below, and select remove
372
* Import the mono audio file from the Project bin in the timeline with drag and drop
373
374
Once that is done you can remove the part before the presentation this way:
375
* In the timeline you can zoom at the maximum level 
376
* Use the cisors to divide the zone in two, you only need to click once with the left click to separate two zones
377
* Select the arow again (on the left of the cisors) and right click on the zone to remove, and select remove
378
* Do that for both the video and the audio tracks, then move both to the left to remove the gap done by the removal if there is one.
