Conservatism, progressive and regressive change – framing in #OpenStreetMap politics
▻http://blog.imagico.de/conservatism-progressive-and-regressive-change-framing-in-openstreetmap
A bit more than half a year ago i analyzed the political structure of the OpenStreetMap Foundation in the aftermath of the previous board elections. I identified two main factions within the OSMF membership – the craft mapping supporters and the corporate and professional interest faction. In terms of power balance these dominate the OSMF membership about 2:1. That is not representative for the OSM community obviously and as i pointed out back in the election analysis there are likely distinct other factions within the overall OSM community that are not adequately represented in the OSMF membership. Still, these two large factions are also present in the OSM community overall and their diverging views manifest frequently in policy related and other discussions.
I also pointed out that the craft mapping supporters are largely defined by a common set of values while the corporate and professional interest faction is defined through common interests. That is something to keep in mind in the following.
The reason why i revisit this topic now is that a new narrative has come up and is being communicated in the past months in OSMF politics – that is the need for change for OpenStreetMap and of conservative opposition from craft mappers against it. This narrative is largely coming out of the corporate interest faction and is framing the craft mapping supporters as conservative and opposed to any kind of change in principle and themselves as being the advocates of urgently necessary change. An OSMF board member has in public communication recently indicated to being inclined to adopt this narrative. I will get to that in more detail later.
What i did not discuss in my election analysis was how the factions i identified came into being historically. To get a realistic impression on the nature and the motivation of the different political movements in OpenStreetMap understanding the history of the project is paramount.
TL;DR: The framing of craft mapping supporters in OpenStreetMap as conservatives opposed to change is inappropriate given the historic context and present day work of craft mappers all over the world towards progressive change. It has been created by regressive, revisionist interests that would like to roll back the ongoing democratization of geographic knowledge and its collection OpenStreetMap stands for in pursuit of short sighted economic goals.
Et #gouvernance donc, ce qui semble aussi poser problème chez #ubuntu cf :
Dans les forums d’Ubuntu, le patron de Canonical a pris la parole. Le fait est rare et témoigne d’une situation tendue, en écho aux inquiétudes de la communauté.
Elle évoque notamment la baisse croissante de ses interactions avec Canonical, l’absence de vraie liaison, la propre absence de Shuttleworth dans ces rapports, ou encore le désengagement progressif de l’entreprise des Ubuntu Community Team et Ubuntu Community Council. Dans une longue réponse, Shuttleworth cherche à rassurer : il n’a jamais été aussi impliqué. Les dernières années ont été consacrées à assurer une vraie stabilité dans le temps à Ubuntu, lui prenant tout son temps.
Il dit partager les inquiétudes de la communauté et s’estime frustré lui aussi de l’absence d’une figure de proue au sein de Canonical pour gérer la liaison avec la communauté. Il reconnaît également que la mission du Community Council – notamment régler les conflits entre membres – est souvent très délicate.

Katie Bouman - Insolite : la 1ère photo d’un trou noir s’est affichée sur un MacBook Pro
▻https://www.mac4ever.com/actu/142719_insolite-la-1ere-photo-d-un-trou-noir-s-est-affichee-sur-un-macbook
Hier, la première photographie d’un trou noir était dévoilée sur le net, créant le buzz très rapidement. En effet, le cliché est présenté comme une avancée scientifique majeure, dépassant le seul domaine de l’astronomie. Longtemps considérée comme impossible à réaliser, l’opération a demandé des années de préparations, huit radiotelescopes coordonnés à travers le monde et un soupçon de bonnes conditions.
Au-delà du projet Event Horizon Telescope, des 200 chercheurs mobilisés et des moyens techniques mis en œuvre, c’est un simple MacBook Pro d’une jeune diplômée du MIT, qui a affiché en tout premier cette image du trou noir super massif, situé dans la galaxie M87, à 55 millions d’années lumière de la Terre.
Image Katie Bouman
Embauchée il y deux ans, Katie Bouman a mis au point un algorithme qui a permis de combiner tous les clichés pris -en avril 2017- en un seul. Finalement, la photo ci-dessus a pu être prise lorsque l’image définitive du trou noir est enfin apparue sur l’écran de son MacBook Pro.
Pour la petite histoire, ce sont 5 pétaoctets de données enregistrées par les huit observatoires, qui ont été nécessaires pour dévoiler ce trou noir. Cette masse de données a été impossible à transférer numériquement vers le laboratoire où travaillait Katie Bouman et a du faire l’objet d’un transport spécial, pour acheminer les quelques 500Kg de disques durs.
Elle utilise quoi comme ordi ? J’arrive pas à voir sur la photo et j’ai pas trouvé dans l’article. :)
Tant qu’à faire :
The breathtaking image from the #EventHorizon telescope is a real achievement for science, and a nice demo of the power of collaboration. Also nice to see (in a behind-the-scenes video shared on the bird site) some laptops involved were running #Ubuntu!

Sur la photo, ça a bien l’air d’un MacBook pas tout jeune, vu la connectique (pas USB-3).
EDIT : ah ben c’est dans le titre…
@simplicissimus oui c’est dans le titre et « MacBook Pro » apparaît 3 fois en tout en 1/4 de page.^_^
Depuis, elle se fait harceler. Tous les journaux ont titré « victime de son succès » genre shaming. Mais elle se fait agresser par des mecs que son succès dérange.
Et Unity, est très bien !!! J’aime pas GNOME non plus (ni KDE, ni mate, ni cinamon, ni lxce...)
Je suis resté deux jours sous Unity, à sa sortie. Ça m’a suffit et depuis je suis sous Xfce avec Xubuntu.
Je suis resté 5 ans sous Unity, et je me demande comment l’installer dans la version communauté qui semble moins stable que du temps d’Ubuntu. Le problème, c’est Mir.

#ubuntu - Why does #mariadb keep dying ? How do I stop it ?
▻https://askubuntu.com/questions/750604/why-does-mariadb-keep-dying-how-do-i-stop-it
I am running MariaDB 10.0.23-0 on Ubuntu 15.10 as a LAMP server. Running sudo /etc/init.d/mysql start results in:
Job for mariadb.service failed because a timeout was exceeded. See “systemctl status mariadb.service” and “journalctl -xe” for details.
Have a closer look at the apparmor="DENIED" messages (if #apparmor is activated on your OS) as this could be an issue during mariadb start.
De mon côté, j’ai du appliquer la solution du post ▻https://askubuntu.com/a/964928 donc sudo aa-disable /usr/sbin/mysqld & reboot.
Ça ne touche que ubuntu ? Car MariaDB est surtout par défaut sur Debian. LAMP lui est relié.
Au départ j’ai cru a dying, genre le projet se meure.
@sandburg je n’ai pas eu le pb sous debian stretch, ni sur une autre install d’ubuntu de même version. Si tu ne vois pas de trace de mysqld dans la sortie de aa-status tu ne devrais pas rencontrer le problème :)

How To Set Up a Network Bridge for LXD Containers
▻https://hackernoon.com/how-to-set-up-a-network-bridge-for-lxd-containers-98e3e7d1f273?source=rs
Most of our web applications run in LXD containers. Not without reason LXD is one of the most important features of #ubuntu Server for me. There are many ways to access a web application in an LXD container from outside. For example, you can use a reverse proxy to control access to the containers. Another possibility is to set up a network bridge so that the containers are in the same network as the container host (the Ubuntu server). In this article I would like to describe how to set up a network bridge for LXD containers.Network Bridge for LXD ContainersTo set up a network bridge under Ubuntu, you need to install the bridge-utils:$ apt install bridge-utilsThen you can set up the network bridge.Ubuntu 16.04Up to Ubuntu 16.04 Ubuntu uses ifupdown to set network connection settings.

Understanding #ufw
▻https://hackernoon.com/understanding-ufw-8d70d5d8f9d2?source=rss----3a8144eabfe3---4
Ubuntu Firewall for humansI have always been scared of IP tables. If you want to know the reason check out the man page for the same. Though I have heard from many people that #iptables are more robust and secure, I have never used them because it has always been daunting. I personally feel that if I am not comfortable with something like IPtables and still use it I might add more #security holes while not leveraging the benefits it provides. So I have stuck to using ufw for now. It is for the same reason that I prerfer Ubuntu over other flavors. Familiarity breeds confidence and I know that I will make less blunders. Donot consider this as a promotion of Ubuntu over other more secure flavors, because it is not. It is just my personal preference.Side note : Did you know that “Ubuntu” is (...)
Latest update to Thunderbird 60.2.1 on 18.04 - Lightning calendar missing - Ask Ubuntu
▻https://askubuntu.com/questions/1084059/latest-update-to-thunderbird-60-2-1-on-18-04-lightning-calendar-missing
After completing an Ubuntu automatic software update (15 Oct 2018) that included Thunderbird 60.2.1 the Lightning calendar is now missing. When I click on Thunderbird’s Add-On tab to see if there’s an update for Lightning I’m told that all the versions of Lightning available there are not compatible with the updated Thunderbird release. All my calendar data is no longer available to me - HELP!!
...
Same here, on (Ubuntu based) Linux Mint 19. It seems to be a thunderbird issue but the update should not have been passed through when it breaks what many regard as core functionality.
A solution is posted on the Linux Mint forums:
I ran into this problem today in Mint 19 when Tbird 60.2.1 was installed through the Update Manager. Removing the Lightning add-on from Tbird and installing the “xul-ext-lightning” package allowed me to recreate my calendar and connect it to Google Calendar.
So the solution is:
remove the lightning add-on in Thunderbird;
exit from Thunderbird;
install xul-ext-lightning package with
sudo apt install xul-ext-lightning
(it will pull more packages in).
restart Thunderbird.
My previous settings had been retained and I did not need to recreate my calendar.

Je partage pour les contrecarrer !
Preuve par l’absurde…
Quand Microsoft utilise des standards (xml + zip pour son format word), produit des standards (Unicode, XPS), ouvre ses outils (vcpkg), s’aligne sur des standards (#Vulkan, odt), fournit des langages (C#, .Net) c’est toujours dans son intérêt économique !!!
Cet objectif n’est pas compatible avec celui du logiciel libre : être un bien collectif, partageable et ouvert.
Donc ne vous laissez pas prendre par le discours de Microsoft.
Et rappelez vous : Microsoft ne libère pas ses codes source et encore moins sous licence libre.
