Installing and running Node Solid Server
The primary implementation offered of Solid is written in Javascript based on Node.js. It should run on versions later than version 8. It is being developed on Github and is released with the liberal MIT license to NPM. To give it a spin, you can download Node.js, including npm, and get it running quickly. We have an extensive module README that provides an overview of the many options of the server and is very useful a development environment. For a simple single-user production installation, we provide an example for Debian systems:
Example install: Solid Server on Debian GNU/Linux
Following these instructions, we install Node.js and npm like this
$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
$ sudo apt-get install -y nodejs build-essential
As root, you can now install the server globally:
$ npm install -g solid-server
Now, you need to decide what is going to be your hostname, we will use your.host.example.org in the following. You should also decide where you want to keep the files the server needs to run. The configuration, data, and supporting metadata database can be kept separate if you want, but we’ll keep them together.
Since everything going on with a Solid server is encrypted, you will need a SSL key and certificate. This can be obtained from e.g. Let’s Encrypt. The easiest way to do this is to use certbot, to do this on Debian Stable, you need a backported package. To obtain that, add this line to your /etc/apt/sources.list:
$ deb http://ftp.debian.org/debian stretch-backports main
Then, certbot can be installed with:
$ apt-get update
$ apt-get -t stretch-backports install certbot
Then, request and install the certificate using:
$ certbot certonly --authenticator standalone -d your.host.example.org
Then, go,
$ solid init
You will be prompted for several things, it could look like this:
? Path to the folder you want to serve. Default is /var/www/your.host.example.org/data
? SSL port to run on. Default is 8443 443
? Solid server uri (with protocol, hostname and port) https://your.host.example.org
? Enable WebID authentication Yes
? Serve Solid on URL path /
? Path to the config directory (for example: /etc/solid-server) /var/www/your.host.example.org/config
? Path to the config file (for example: ./config.json) /var/www/your.host.example.org/config.json
? Path to the server metadata db directory (for users/apps etc) /var/www/your.host.example.org/.db
? Path to the SSL private key in PEM format /etc/letsencrypt/live/your.host.example.org/privkey.pem
? Path to the SSL certificate key in PEM format /etc/letsencrypt/live/your.host.example.org/fullchain.pem
? Enable multi-user mode No
? Do you want to have a CORS proxy endpoint? Yes
? Serve the CORS proxy on this path /proxy
? Do you want to set up an email service? No
config created on /root/config.json
Then, you need to create the paths that you entered. You would also need to copy the config.json file to where you indicated it should be.
You should be able to start the server now with:
$ solid start
However, we recommend that you use e.g. systemd to automatically start and stop the server.
Since it is a security risk to run the server as root, you should create a user for it, with e.g.
$ adduser --system --ingroup www-data --no-create-home solid
Then, create a file /lib/systemd/system/solid.service containing
[Unit]
Description=solid - Social Linked Data
Documentation=https://solid.inrupt.com/docs/
After=network.target
[Service]
Type=simple
User=solid
WorkingDirectory=/var/www/your.host.example.org
ExecStart=/usr/bin/solid start -v
Restart=on-failure
[Install]
WantedBy=multi-user.target
Then, symlink that:
$ ln -s /lib/systemd/system/solid.service /etc/systemd/system/multi-user.target.wants/
Now, make the directories owned by the user:
$ cd /var/www/your.host.example.org/
$ chown solid:www-data config/ data/ .db/
You may also need to make the config.json file readable to the unprivileged user.
Now, starting the server should be done by:
$ systemctl start solid.service
You should now also have the other facilities provided by systemd available, and it should start automatically after the machine is booted.
The certificate needs to be renewed every few months, and you should modify your Let’s Encrypt setup to use the webroot plugin, which is better to use when the server is running. To do so, modify the file /etc/letsencrypt/renewal/your.host.example.org.conf . Make sure the authenticator line reads:
authenticator = webroot
Also set:
webroot_path = /var/www/your.host.example.org/data
[[webroot_map]]
your.host.example.org = /var/www/your.host.example.org/data
Then, create a cron job by creating a file in /etc/cron.daily/ that contains:
#!/bin/bash
certbot renew -w /var/www/your.host.example.org/data/Now, you should have a working Solid server! Enjoy!

iOS and Keyboard Shortcuts
Most of the keyboard shortcuts you’re used to using on your Mac will work on your iPad Pro, iPad, and iPhone. Some apps have specific keyboard shortcuts. You might want to check any official manuals for third-party apps not mentioned here to further speed up your workflow.
If you’re using the iPad Pro with Smart Keyboard, or an iPad and wireless Apple keyboard, you’re all set to go. If your Bluetooth keyboard is aimed at Windows use, you’ll need to get used to substituting particular keys.
The two most common substitutions are Ctrl in place of Apple’s Cmd, and Alt in place of Option. The layout may also be different, depending on your localization. Apple keyboards place the @ symbol on Shift + 2, for example. This is different than the standard UK layout.
Some of these shortcuts may not work, or may only work on the iPad Pro. In particular, the iPad Pro has a useful shortcut where holding down the Cmd key shows all available shortcuts for a given app. Try it in Safari, on the Home screen, or even in a third-party app like Slack.

Le Guide Ultime de la Batterie Lipo
Qu’est-ce qu’une batterie Lipo ?
La batterie Lipo, pour « Lithium Polymer Batterie », est un outil devenant de plus en plus courants sur les tournages, en réalité cette technologie est présente partout sous différentes formes, comme par exemple dans les Smartphones, les Ordinateurs portables et les tablettes.
Ce guide est à destination des opérateurs ou assistants caméras souhaitant s’informer sur les origines de la technologie de batterie Lipo et comment en prendre le meilleur soin.
Il existe différents types de batteries comme nos bonnes vieilles batteries V-Lock et batteries DV (NPF, LP-E6 et plus encore), mais depuis l’arrivée des drones et des nacelles, dérivés des utilisations des hobbyists, sont apparus les Batteries Lithium Polymer ou Lipos, Leur gros avantage provient de leur construction légère ainsi que de leur haute puissance. Toutes les capacités existent, de la batterie 100mAh avec une seule cellule, Jusqu’aux batteries 6 cellules 22000 mah que l’on peut trouver sur les gros drones.
Ces batteries nécessitent cependant un entretien particulier afin d’en assurer la durée de vie la plus longue, ou plus simplement éviter une catastrophe dûe à un mauvais entretien. On parle içi de batterie pouvant prendre feu et littéralement endommager votre matériel ou pire…. VOTRE LOCAL !
Ce guide couvre la technologie au stade où elle se trouve aujourd’hui, la batterie Lipo s’étant considérablement amélioré avec le temps, nous ne sommes pas à l’abri d’avoir dans le futur des batteries Lipos aussi robuste que nos batterie V-Locks (A ce propos, vous vous souvenez les chargeurs de batteries V-Locks qui prenaient feu dans le temps ?)
