Raphaël Hertzog: My Free Software Activities in November 2015
My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it s one of the best ways to find volunteers to work with me on projects that matter to me.
Debian LTS
This month I have been paid to work 21.25 hours on Debian LTS. During this time I worked on the following things:
- From November 2nd to November 8th, I was handling the LTS frontdesk, triaging new CVE, filing bugs, and ensuring timely answers on the mailing list. I pushed 26 commits to the security tracker. While investigating CVE-2015-7183 I discovered more embedded copies of nspr (which resulted in #804058). I also commented on the upstream fix for CVE-2015-5602 which looked like insufficient.
- Prepared and released DLA-339-1 on libhtml-scrubber-perl fixing one CVE.
- Prepared and released DLA-350-1 on eglibc with a non-trivial backport fixing one CVE.
- Prepared and released DLA-353-1 on imagemagick fixing two security issues without CVE yet (and marking one as not-affecting squeeze).
- Added a third patch after review by the upstream author on my still pending bouncycastle update. The upstream author asked me to further defer the update as they have some related fixes coming up.
- I did preparatory work for DLA-352-1 by identifying the upstream commits that fixed the security issue.
- I spent some time checking issues that have been assigned for a long time without any visible progress being made in the hope to unblock them (libvncserver, pound, quassel).
Fran ois-R gis Vuillemin, Juliette Belin and Rapha l HertzogI sponsored pylint-plugin-utils_0.2.3-2.dsc for Joseph Herlant to fix a release critical bug. I filed 806237 against lintian. I filed more tickets upstream, related to my Kali packaging work: one against sddm, one against john Other Debian-related work Distro-Tracker. I finally merged the work of Orestis Ioannou on bug #756766 which added the possibility to browse old news of each package. Debian Installer. I implemented two small features that we wanted in Kali: I fixed #647405 to have a way to disable deb-src lines in generated sources.list files. I also filed #805291 to see how to allow kernel command line preseeding to override initrd preseeding the fix is trivial and it works in Kali. I just have to commit it in Debian, I was hoping to get an ack from someone in charge before doing it. Thanks See you next month for a new summary of my activities.

Now you should see all the video sequence editor controls:
Setup the properties for your project
Click the context menu under the strip editor panel and change the panel to a Properties panel:
The video file we are playing with is 720p, so it seems reasonable to use 720p for the output too. Change that here:
The input file is 25fps so we need to use exactly the same frame rate for the output, otherwise you will either observe the video going at the wrong speed or there will be a conversion that is CPU intensive and degrades the quality. Also check that the resolution_percentage setting under the picture dimensions is 100%:
Now specify output to PNG files. Later we will combine them into a WebM file with a script. Specify the directory where the files will be placed and use the # placeholder to specify the number of digits to use to embed the frame number in the filename:
Now your basic rendering properties are set. When you want to generate the output file, come back to this panel and use the Animation button at the top.
Editing the video
Use the context menu to change the properties panel back to the strip view panel:
Add the video file:
and then right click the video strip (the lower strip) to highlight it and then add a transform strip:
Audio waveform
Right click the audio strip to highlight it and then go to the properties on the right hand side and click to show the waveform:
Rendering length
By default, Blender assumes you want to render 250 frames of output. Looking in the properties to the right of the audio or video strip you can see the actual number of frames. Put that value in the box at the bottom of the window where it says 250:
Enable AV-sync
Also at the bottom of the window is a control to enable AV-sync. If your audio and video are not in sync when you preview, you need to set this AV-sync option and also make sure you set the frame rate correctly in the properties:
Add the other sound strip
Now add the other sound file that was recorded using the lapel microphone:
Enable the waveform display for that sound strip too, this will allow you to align the sound strips precisely:
You will need to listen to the strips to make an estimate of the time difference. Use this estimate to set the "start frame" in the properties for your audio strip, it will be a negative value if the audio strip starts before the video. You can then zoom the strip panel to show about 3 to 5 seconds of sound and try to align the peaks. An easy way to do this is to look for applause at the end of the audio strips, the applause generates a large peak that is easily visible.
Once you have synced the audio, you can play the track and you should not be able to hear any echo. You can then silence the audio track from the camera by right clicking it, look in the properties to the right and change volume to 0.
Make any transforms you require
For example, to zoom in on the speaker, right click the transform strip (3rd from the bottom) and then in the panel on the right, click to enable "Uniform Scale" and then set the scale factor as required:
Render the video output to PNG
Click the context menu under the Curves panel and choose Properties again.
Click the Animation button to generate a sequence of PNG files for each frame.
Render the audio output
On the Properties panel, click the Audio button near the top. Choose a filename for the generated audio file.
Look on the bottom left-hand side of the window for the audio file settings, change it to the ogg container and Vorbis codec:
Ensure the filename has a .ogg extension
Now look at the top right-hand corner of the window for the Mixdown button. Click it and wait for Blender to generate the audio file.
Combine the PNG files and audio file into a WebM video file
You will need to have a few command line tools installed for manipulating the files from scripts. Install them using the package manager, for example, on a Debian or Ubuntu system:

sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don t get centurylink easter eggs in my search results when I use this interface.
eth9 is the local gigabit transceiver. Attached directly to a SIP phone which bridges to a gigabit switch, on which the Ubiquity equipment participates.
lo is the local loopback interface, of course. Good old 127/8
usb1 is the 100Mbit USB NIC to which the WRT54G with ssid colliertech.org is attached. The vast majority of the traffic originates on this interface.
My friend Ross Mayhew and I enjoyed a perfect Autumn afternoon yesterday, full of colours on the Bluff Trail. Not all of these photos do justice to the splendour and intricate detail I had hoped to capture, but I hope you enjoy them all the same. Click the photo to start the slideshow.
The definition of thick-skinned in different dictionaries ranges from not easily offended to largely unaffected by the needs and feelings of other people; insensitive , going through able to ignore personal criticism , ability to withstand criticism and show no signs of any criticism you may receive getting to you , an insensitive nature or impervious to criticism . It essentially describes an emotionally detached attitude regarding one s social environment, the capacity or ignoring or minimizing the effects of others criticism and the priorization of the protection of one s current state over the capacity of empathizing and taking into account what others may say that don t conform to one s current way of thinking. It is essentially setting up barriers against whatever others may do that might provoke any kind of crisis or change in you.
There are a few underlying assumptions in the use of this term as a something good to have, when it comes to interactions with your own community:
In the first place, it assumes that your own community is essentially hostile to you, and you will have to be constantly in guard against them. It assumes that it is better to set up barriers against the influence of others within your own comunity, because in fact your own peers are out there essentially to hurt you. Or, at least, they do not care a damn about you.
In second place, it assumes that changes are wrong, that personal evolution is wrong, and that the more insensitive you are to your peer s opinions, the best, because they really have nothing to contribute to help you grow as a person. I m smart; you re dumb. I m big; you re little. I m right; you re wrong; And there s nothing you can do about it. (from the film 
When the main recommendation when the level of aggressiveness within a community is that someone has to make their skin thicker, they are assuming that a bullying environment will help the results. This is nothing new. It s the same theoretical base that you can see in hazing and in other activities involving harassment, abuse or humiliation in college, when initiating a person into some groups. 
Debian was not generally seen as a bleeding-edge distribution, but it offered a perfect combination of stability and up-to-date software in our field when we chose the platform for our signature verification project. Having an active Debian Developer in the team also helped ensuring that packages which we use were in good shape when the freeze, then the release came and we can still rely on Jessie images with only a few extra packages to run our software stack.
Not having to worry about the platform, we could concentrate on the core project and I m proud to announce that 
I would like to thank you all, who helped making Debian an awesome universal operating system and hope we can keep making every release better and better!
