… or look at this great Chris Beams post: http://chris.beams.io/posts/git-commit/
Everything started ’cause I requested a colleage about stop ending the messages with a period. And then, I realised that my messages starting with “adding”, “fixing” and other continous pasts doesn’t has any sense. So, I started writing in imperative.
Thanks Chris :·)
Hi @channel!
Last weeks I worked with Vibbo‘s Android team. Changing from one team to another one is great to learn new things. You know everything about moving outside of the comfort zone so I will not talk about it… :·)
This article tries to list all the times that git rebase broke my heart. I know that there’s a hot conversation about merging from develop to your branch or rebasing on develop. I always merged to fix conflicts, and some members of the Vibbo crew asked me to rebase over merge, so I went forward with rebasing. In addition, I tried to spread the word to another team… and well, I regret it.
The broken heart facts:
– When you rebase on another branch, you are requested to resolve every conflict it happened, commit by commit. So, if the branches are not too small, you will be asked several times. If you resolve conflicts on ten different files, it’s ok. But, if you have to resolve conflicts ten times in the same file… madness.
– If you missed a conflict and you screwed the whole code (’cause you are not perfect, my friend), you don’t have a “merge commit” where you can find your mistake. You have rebased. No merge commit. Good luck!
– Push force will be your new friend but HEY. git push origin –force pushes your branch to origin, right? Well, yes, but only partially. In Windows (at least, the version I had) it pushes ALL your branches. So, if you had an old version of develop, you will push it and screw all your friends. There’s a –force-with-lease version in the latest versions of git but hey, it’s not the standard –force.
– The Pull Request conversation gets disordered. A common Pull Request seems a Twitter timeline. Two commits, one comment, one commit, three comments. Then, you push force your just rebased branch, and all the messages are moved to the start of the conversation and all the comments after them. Goodbye, timeline!
Conclusion: if you are alone in a project or you work with a very committed team that loves living at risk, rebase could be a good option for you. But if you are in a real-world, you are an average git user or you work with average git users… don’t rebase.
You heard about Jenkins and you want to try it. Good news: it’s so simple to do it in a production environment. So, skip trying it at your localhost and then installing it again in your production environment. The steps are these:
1. Get a production server. We use to get it at gandi.net. To build Android apps you’ll need 2GB of memory. About the number of cores: it will work with only one core, but if you can afford a machine with more cores, gradle will use them. Fewlaps’ Jenkins has two cores and it performs great.
2. Install Java 8. You can also use Java 7 but… well. At some time, someone, will write a lambda, and you will need to update to Java 8 :·)
su root echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" > /etc/apt/sources.list.d/webupd8team-java.list echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" >> /etc/apt/sources.list.d/webupd8team-java.list apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886 apt-get update apt-get install oracle-java8-installer java -version exit
3. Install Jenkins: https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins
4. http://yourserver:8080 it works! (note that it’s not too fast starting the daemon)
5. Install git, mercurial… All the things that Jenkins will need to pull your projects from your repos. You know:
apt-get install git apt-get install mercurial
… and so on
Important: before creating any Job, check your security configuration. Create an user for you, another one for every colleague, and grant them the needed permissions. Also check that “anonymous” doesn’t have any permission, and that the “users can register to the environment” box is not checked.

Wep! More info! Your Android SDK will be downloaded at /var/lib/jenkins/tools/android-sdk/
Wep! More info! If you have issues starting an emulator, apt-get install libglu1-mesa

Bones!
Aquest dimecres 17 de febrer he fet una xerrada introductòria de testing, CI i CD sobre Android als Betabeers. Ha estat al Mobile World Centre, al C/ Fontanella 2 de Barcelona. És a dir: a la cosa aquella de Telefònica al costat de Plaça Catalunya.
Vet aquí el video de la xerrada:
El briefing era aquest:
Hola! Soy Roc Boronat, desarrollador Android en Fewlaps. Hace un año y medio creía que testing y CI eran cosas de pijos, así que este último año he escuchado mucho para aprender por qué los grandes lo promueven. En esta charla compartiré mi experiencia sobre testing en Android, TDD, y CI, aplicado a varios proyectos reales. Y todo, desde el punto de vista del que no se lo creía demasiado.
Espero que us sembli interessant! I per suposat, qualsevol feedback és benvingut!
“Es para mi un motivo de orgullo y satisfacción” haver pogut ensenyar la feina què hem fet al Mini Maker Faire 2016, una fira de makers que es fa al CaixaForum, i on crec que el què vam presentar va entusiasmar a més d’un, de deu i de cent.
Bones!
Entre ahir i avui, el meu Flone ha fet avenços genials.
Ahir, vaig quedar amb en Natxo, un entusiasta dels drones i del Flone en concret, que em va ajudar a entendre com funcionava la part elèctrica del Flone, i a soldar la PDB als quatre ESC.
Avui, he conegut en persona a en Víctor, un noi que em va contactar a través d’Instagram, a arrel de que va veure el vídeo de la talladora làser fent tres Flones. Ell ha fet el seu amb la seva impressora 3D! UAU!
La part trista és que tinc el Flone casi casi però no, i en Víctor, tres quarts del mateix. A mi em falla un ESC (o un motor…) i a ell, sembla que la placa.
I direu… i a mi què m’expliques? Doncs t’explico que d’aquest post en pots treure la configuració de la placa MultiWii preparada per a que el Flone funcioni via Bluetooth! Per alguna raó, la placa del Víctor no enviava ni rebia dades via Bluetooth, i al flashejar la placa amb la meva versió sí que ho feia… de manera que hem decidit que el millor seria compartir la meva configuració amb l’univers.
Així que aquí ho teniu! MultiWii 2.3 adaptat al Flone per a connectar via Bluetooth
A quick thought I just had: Good brands are written with left hand. I realized it after writting “tre” at Chrome to open trello.com
Bones!
Després d’unes vacances genials, he tornat a la càrrega fent algunes cosetes al QuitNow!, que teniem acumulades. I per primera vegada he fet un live coding. Si ets desenvolupador i no n’has fet mai cap, atreveix-te! És la versió Badoo i Tinder dels desenvolupadors. I a més a més, tampoc quedes amb ningú. És clavat!
No, en sèrio: es tracta d’un lloc on ensenyar com desenvolupes quelcom en temps real. Apareix el teu pantallot, la teva careta, i un xat. I apa! Jo em pensava que no li interessaria a ningú, però mira. 10 ànimes han arribat a estar alhora mirant com teclejava amb cert sentit… que boig que s’està tornant tot.
Bé, un link al meu perfil, a veure si m’hi enganxeu!
