update LILO GRUB2

But

Les serveurs OVH sont installés avec LILO par défaut, je souhaite installer GRUB2 à la place.
Je suis sous Ubuntu Karmic.

Prérequis

Il faut au prealable installer GRUB1
 apt-get install grub 
et le configurer:
 grub-install /dev/sda 

Recette

Installer GRUB2, et les package ne s'appelle pas "GRUB2":
 apt-get install grub-pc 
Catte installation va mettre en place une étape de transition GRUB1 -> GRUB2. Modifier:
 nano -w /etc/default/grub 
Enlever l'étape de transition par GRUB1
 upgrade-from-grub-legacy 
Vérifier que tout s'est bien passé
 nano -w /boot/grub/grub.cfg  
Supprimer LILO
 apt-get remove lilo 
Rebooter
 reboot

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&

dockerfile multiline to file

Outputing a multiline string from Dockerfile I motsly use a Dockerfile by sourcing from a base ditribution: CentOS or Debian. But I also have a local mirror and would like to use it for packages installation. Espacially on CentOS it is about many lines to write to the /etc/yum.repos.d/CentOS-Base.repo file. Easiest way: one RUN per line The first method that comes in mind is to issue one RUN per line to write. Here you are: RUN echo "[base] " > /etc/yum.repos.d/CentOS-Base.repo RUN echo "name=CentOS-$releasever - Base " >> /etc/yum.repos.d/CentOS-Base.repo RUN echo "baseurl=ftp://packages-infra.mg.rktmb.org/pub/centos/7/base-reposync-7 " >> /etc/yum.repos.d/CentOS-Base.repo RUN echo "gpgcheck=0 &quo

Emacs TypeScript Development

Emacs Configuration for Typescript In order to comfortably develop on Node, React or Angular projects with Emacs, TIDE is a good solution. We have TypeScript code highlight (that is the minimum!) and code completion based on the codebase (not only on locally defined and builtins) In order to achieve that: Install Emacs (24+) Install Node Install Typescript (which will provide "tsserver") Install TIDE and some usefull dependencies Configure Emacs to use all those Node is then installed in " /home/mihamina/Apps/node-v12.18.0-linux-x64/bin ": you should add it to your PATH. Installing Typescript is done with: npm install --save typescript @types/browserify After that, "tsserver" will be in " /home/mihamina/node_modules/.bin " Then comes the installation of TIDE: With the Emacs package manager, M-x package-install , install "tide". Do the same for "web-mode", "flycheck", "company" "js2-mode" and "
