Mon, 27 Feb 2017 22:51:54 +0000

Technology has never been as important as today in politics. Everything is related to numeric data. If we only analyze news around US elections in 2016, it was mostly about email hacks, fake news in daily news feed, or online surveys. Concerned about French elections 2017, I wanted to be a bit more active and do something related the last one: to online surveys.

Six months of Android development

Wed, 25 Jan 2017 14:25:53 +0000

In my current role at Qudini, I started as an iOS developer. My main task was to create and improve our mobile products for iOS devices based on what was already done on Android.

Continuous integration and continuous delivery is something I wanted to do a while ago, specially since Apple accelerated its approval process to publish new apps on its mobile store. It can now takes less than a day to have an update available for your mobile users: continuous integration and continuous delivery makes more sense than ever on mobile apps.

How can a developer do marketing?

Sun, 07 Aug 2016 02:44:17 +0000

Working as a mobile developer, I created multiple apps during last couple years for companies I worked for, and eventually for personal projects. At the beginning, I though the goal for any developer was the release itself: shipping code and moving on, but I quickly found out that it was more frustrating than everything to stop here. That’s how I started thinking about what should be the next step and if a developer can actually do marketing and how.

Retour sur ces 54h de travail acharné.

Les difficultés autour des objets connectés

Sun, 02 Nov 2014 19:27:34 +0000

Ces temps ci, il y a beaucoup de bruits autour des objets connectés. Tous les jours, on découvre de nouveaux articles sur des objets connectés annoncés sur le marché ou financés sur des plateformes de “crowdfunding”. On a bien moins d’informations sur toutes les difficultés liées autour de ces projets innovants. Voici mes conclusions sur les recherches que j’ai faites à ce sujet.

Moto360 ou Withings Activité

Mon, 07 Jul 2014 09:29:37 +0000

De plus en plus de montres connectées font leur apparition, mais d’après moi, la plupart passe à côté de l’essentiel: la montre reste l’un des seuls accessoires masculin, il faut donc la rendre élégante en respectant sa forme historique. C’est pourquoi, je m’intéresse dans cet article principalement aux montres “habillées” et en attendant la sortie de celle d’Apple, je vous propose un comparatif entre la montre connectée de Motorola et celle de Withings, fraichement annoncée.

Mes premiers pas vers le Lean Startup

Sun, 01 Jun 2014 19:44:32 +0000

Ne voulant pas me limiter à mon background technique, j’essaie de plus en plus de développer des notions d’entrepreneuriat dans l’idée d’être plus utile dans mon analyse technique et de continuer la reflexion autour de différents développement d’applications dans une start-up. L’idée est de ne pas se limiter au développement demandé, mais d’essayer d’appréhender toute la chaine de réflexion, à savoir du besoin de clients jusqu’à l’utilisation d’un nouveau service/produit développé et de voir comment celui-ci est utilisé et ce qu’il faut améliorer.

Pour cela, et avec les conseils avisés d’un ami , Maxime Salomon, j’ai commencé à lire The Lean Startup de Eric Ries. Ce livre aborde de nombreux sujets autour de l’entrepreneuriat, du marketing ainsi que de développement de produit à proprement parlé. L’idée est de proposer un cycle itératif de développement pouvant permettre de mesurer rapidement différents paramètres pour faire évoluer un produit en fonction de nouvelles données.

Etant d’un formation plus scientifique, j’ai ce besoin de mettre en pratique ce dont il est question pour mieux comprendre la solution proposée, j’ai aussi un besoin de me documenter sur les différents termes employés pour ne pas passer à côté du sujet, c’est pourquoi je prends mon temps pour lire ce livre, mais je vous propose mon retour d’expérience sur mes premiers acquis et comment j’essaie de les mettre en pratique.

Introduction à Soundcloud

Tue, 22 Apr 2014 22:33:20 +0000

Soundcloud est une des plus grosses plateformes de musique indépendante, c’est plus de 200 millions d’utilisateurs pour ce réseau sociale basé sur le partage musicale. Certains artistes ne publient leurs musiques que sur cette plateforme. C’est aussi la place pour des novices qui veulent essayer leurs titres et se faire connaitre. Vous pouvez aussi y retrouver des discours, des podcasts et tout autres types de contenu audio.

Dans cette optique de toujours avoir de la bonne musique, Soundcloud est disponible sur toutes les plateformes (web et mobile) et l’écoute est gratuite. Pour une utilisation encore plus variée de leur service, SoundCloud propose une API ainsi que de nombreux SDK (Javascript, Ruby, Python, PHP, Cocoa et Java). Nous allons voir ensemble comment intégrer SoundCloud dans une application mobile iPhone.

Comment réussir son premier entretien

Tue, 18 Feb 2014 08:00:48 +0000

Passer un entretien pour un poste est toujours un peu stressant. Suivant comment ce stress est géré, la personne peut donner une image de quelqu’un qui n’est pas sûre de soi par ses gestes (tremblement, bafouillement, se frotter les mains) ou par ses mots (ne pas finir ses phrases, phrases à rallonge trop complexe, etc). Difficile dans ces cas là de donner la meilleure image de soi pour montrer qu’on est travailleur, motivé et prêt à l’emploi.

Je vous propose par mon retour d’experience quelques conseils simples.

Spotify et ses outils d'intégration

Sat, 08 Feb 2014 14:46:43 +0000

Après avoir travaillé avec les technologies Deezer, nous allons voir quels outils sont proposés par Spotify pour une intégration web ou mobile. Spotify proposant une écoute gratuite sur son client ordinateur et depuis peu sur mobile (parsemé de publicité), il se démarque de Deezer qui nécessite d’avoir un compte Premium pour une utilisation sur smartphone. L’intégration pour les développeurs est aussi différente, mais à quelle mesure? C’est ce que nous allons voir.

Hackathon: ma maison connectėe

Wed, 11 Dec 2013 14:16:38 +0000

Les objets connectės sont de plus en plus présents chez nous. On y retrouve des produits comme des ampoules, des enceintes audio ainsi que des prises intelligentes. On y retrouve aussi des produits plus innovants comme le pèse personne de Withings, la balle de Sphero, la lampe connectée “holî” ou encore le capteur pour plante de Parrot.

C’est dans cette optique là que l’entreprise Direct Energie a organisée un hackathon autour des objets connectés pour présenter différentes solutions autour de la maîtrise d’énergie et des objets intelligents.

C’est en tant que support technique sur le produit “holî” et son SDK que j’y ai participé, afin d’aider les développeurs à se familiariser avec l’outil. Ayant fait un hackathon du côté développeur, c’est un nouveau retour d’expérience cette fois ci du côté partenaire.

SpriteKit, un framework iOS7 pour jeu video

Sat, 23 Nov 2013 12:56:53 +0000

Au jour d’aujourd’hui, les jeux vidéos sont de plus en plus présent. Avec l’univers du smartphone, il est de plus en plus facile d’embarquer des jeux vidéos avec nous et ce partout.

Plusieurs jeux ont eu un tel succès qu’il reste difficile d’ignorer cet utilisation de nos téléphones en tant que console. A n’en citer que quelques-uns: DoodleJump, AngryBird ou encore le fameux CandyCrush.

Depuis la sortie d’iOS7, Apple a rajouté un framework de jeu vidéo 2D directement dans son SDK: SpriteKit. Nous allons voir ensemble comment l’utiliser.

Fhacktory, un hackathon nouvelle génération

Fri, 04 Oct 2013 20:40:32 +0000

Un hackathon est l’équivalent d’un marathon sur le domaine du développement informatique. Bien connu sous le système de “Startup Weekend”, ce principe a été adapté dans l’informatique au développement de projet en un temps donné. Le but est de monter en un weekend une équipe qui évoluera autour d’une idée et proposera une solution à un problème. J’ai récemment participé à l’un d’entre eux, le Fhactory: un hackathon se définissant “100% hack, 0% bullshit” et voici mon retour d’expérience.

À la découverte des outils de Deezer

Mon, 16 Sep 2013 08:00:03 +0000

Nous allons voir ensemble, comment les utiliser, à quelles fins et quelles en sont les limites. Pour le SDK, je ne m’intéresserai qu’à celui pour iOS.

iJump, une application iPhone pour les parachutistes

Fri, 26 Jul 2013 10:04:34 +0000

En lançant le portail web de météo Weather, mon idée était d’en faire un support pour une version mobile.

En intégrant différentes notions associées à la chute libre et avec l’aide de la Fédération Française de Parachutisme, voici iJump: l’application mobile pour les parachutistes.

La formation au développement mobile

Wed, 03 Jul 2013 07:02:42 +0000

Il y a maintenant 6 mois, j’ai commencé une formation afin de devenir enseignant sur les languages Cocoa et Objective-C.

Cette formation a compris plusieurs étapes, chacune finissant par un examen afin de passer à la suivante:

Une partie pédagogique au cours de laquelle nous sommes évalués sur notre capacité à communiquer un message, à faire comprendre une technologie, à la gestion de notre temps de parole ainsi qu’à la tenue une classe.
Une partie technique où l’évaluation se portait exclusivement sur la connaissance des technologies auxquelles je m’étais proposé. Pour ma part, cela m’a permis de revoir les fondements de Cocoa ainsi que de l’historique la société NeXT.

Voici mes différents retours sur ma première experience de formateur.

Réalisation: Weather, un portail météo pour la chute libre

Thu, 29 Nov 2012 17:44:47 +0000

Contexte:

Ayant récemment été initié à la chute libre, cette discipline est largement dépendante de la météo.

Malheureusement, trouver la météo en temps en “temps réel” suivant son centre de saut n’est pas chose aisé. Même à 10km de son centre de saut, la différence météorologique peut être significative quant à la pratique du parachutisme.

C’est pourquoi j’ai décidé de developper un portail web permettant de consulter le dernier relevé météo de n’importe quel centre de saut en France, datant de moins de 12h.

Wed, 25 Jul 2012 11:37:41 +0000

Après avoir fini ma première année d’étude en informatique, j’ai eu l’idée de réaliser un site internet pour une première experience professionnelle à mon compte.

Des idées à l’étude:

Après quelques idées ainsi que des conseils avisés d’un jeune entrepreneur, j’ai décidé de choisir la branche du tourisme et plus précisément le domaine de l’hotellerie de plein air.

En effet, ce domaine est peu exploité sur internet alors que le nombre de réservation de séjour en camping continuait d’augmenter.

Réalisation: iDevWeb - Gestion de projets web

Mon, 14 May 2012 14:48:35 +0000

Quand on est développeur web, il arrive qu’on travaille sur plusieurs projets en même temps et qu’on conserve d’anciens projets sans les supprimer.

En utilisant MAMP sous MAC OS X, il faut accéder à l’url exacte du dossier pour pouvoir accéder au site web, il n’existe pas par défaut une page qui indexe les dossiers contenus dans le dossier de développement.

C’est là que j’ai eu l’idée de développer un petit portail en php qui listerait les dossiers contenus dans mon dossier de développement, cela éviterait de devoir se rappeler du nom du projet ainsi que du chemin exacte pour y accéder.

Réécriture d'urls avec htaccess sous CodeIgniter

Wed, 14 Mar 2012 10:39:03 +0000

Le principe de réécriture d’urls permet de “transformer” les urls pour référencer plus simplement des pages clés d’un site internet. Pour cela on utilise le fichier htaccess, un fichier caché situé à la racine du dossier de l’application.

Nous allons voir comment est géré par défaut les urls dans le framework CodeIgniter et comment les modifier pour éviter de perdre le référencement déjà acquis sur un site web.

CodeIgniter et son modèle MVC

Sun, 04 Mar 2012 18:21:19 +0000

CodeIgniter est un framework php open source basé sur une architecture MVC.

Rappel:

L’architecture MVC (Modèle – Vue – Controller) permet d’organiser plus simplement une application.

Modèle : type de données, objet
Vue: interface avec l’utilisateur
Contrôleur: traitement des données, gestion des évènements.

Un framework est un kit qui permet de créer la base d’une application plus rapidement et avec une structure plus solide.

Présentation:

CodeIgniter a pour avantage d’être libre mais surtout d’être plus léger comparé aux autres frameworks php connus. Il possède un “guide utilisateur” (en ligne sur le site officiel et localement dans le dossier téléchargé) plus que complet qui propose de nombreux exemples d’applications. La mise en place est intuitive et aucune configuration n’est nécessaire pour une utilisation simple.
