10 Tips for More Effective PowerPoint Presentations

“Oh no! Not another boring PowerPoint presentation! My eyes, my eyes…!!!” How much does it suck to be in the audience for yet another drawn-out, boring, lifeless slideshow? Worse yet, how much does it such to be the one giving it? The truth is, bad PowerPoint happens to good people, and quite often the person giving the presentation is just as much a victim as the poor sods listening to her or him. Here are ten tips to help you add a little zing! 1. A little planning goes a long way. That’s bass-ackwards. And make sure your script follows good storytelling conventions: give it a beginning, middle, and end; have a clear arc that builds towards some sort of climax; make your audience appreciate each slide but be anxious to find out what’s next; and when possible, always leave ‘em wanting more. 2. At any given moment, what should be on the screen is the thing you’re talking about. Plan your presentation so just one new point is displayed at any given moment. 3. Congratulations. 4. 5. 6. 7.

The 10/20/30 Rule of PowerPoint I suffer from something called Ménière’s disease—don’t worry, you cannot get it from reading my blog. The symptoms of Ménière’s include hearing loss, tinnitus (a constant ringing sound), and vertigo. There are many medical theories about its cause: too much salt, caffeine, or alcohol in one’s diet, too much stress, and allergies. Thus, I’ve worked to limit control all these factors. However, I have another theory. As a venture capitalist, I have to listen to hundreds of entrepreneurs pitch their companies. To prevent an epidemic of Ménière’s in the venture capital community, I am evangelizing the 10/20/30 Rule of PowerPoint. Ten slides. So please observe the 10/20/30 Rule of PowerPoint.

PHP - Rediriger sur une autre page (redirection) N'importe quel webmaster réalise un jour qu'un de ses fichiers possède un nom qui ne convient pas ou que l'arborescence des fichiers doit être modifiée. Cependant, s'il est relativement facile de changer les liens sur son site, il est beaucoup plus difficile de faire changer les liens externes sur les autres sites. Par ailleurs, lorsque l'on change les pages de place, les moteurs de recherche risquent d'envoyer les utilisateurs dans le vide ou, pire, réinitialiser tout le référencement de la page. Heureusement, il existe une solution simple : les redirections, permettant de maintenir la cohérence de la navigation (et du référencement) d'un site, même si l'ensemble des fichiers à changé de place. IMPORTANT : Les en-têtes HTTP Les redirections sont des en-têtes HTTP. En d'autre termes, la fonction header() doit impérativement être utilisée avant tout code HTML. Pour plus d'informations, lire cet article : L'erreur "headers already sent by" Redirection simple Chemin relatif / absolu Exemple

The "Lessig Method" of presentation The "Lessig Method" of presentation is not an official method per se, but many people who know about the work of Stanford law professor, Lawrence Lessig, have been inspired by his presentation style and informally refer to his approach as something unique indeed. Those who have seen Lessig present have been talking about his approach for a while. David Hornik at VentureBlog wrote a post entitled Putting the "Power" in Powerpoint over two years ago. In this post he heaps praise on the presentation style of Lessig. James MacLennan may have been the first to put a label on Lessig's presentation style, calling it the "Lessig Method" which he likens to the Takahashi Method in Japan because Lessig's slides often contain just a single word, short quote, or a photo. Here is a good example of the "Lessig Method" of presentation. See Dick present "Lessig Style"There are more videos of Lessig lecturing and presenting here. Hardt's presentation style is not applicable to every case, of course.

Construire un menu arborescent avec une fonction récursive en PHP | Le Coin du Webmaster Par Webmart | juillet 15, 2008 Un sujet assez difficile à comprendre dans le monde de la programmation web pour plusieurs webmasters qui ont appris par eux-mêmes, dont je fais parti, est la technique de récursivité, où une fonction fait appel à elle-même. Cette fonction est dit récursive dans ce cas, et elle peut être nécessaire dans plusieurs situations, telles que la création d’un menu arborescent complexe où le nombre de sous-catégories n’est pas prévisible. Commençons par la structure d’une base de donnée MySQL simple et typique pour ces catégories. ID Parent Nom 1 0 Félins 2 1 Grands Félins 3 2 Panthères 4 2 Lions 5 1 Petits Félins 6 2 Tigres 8 0 Poissons 9 0 Canins 10 8 Saumons 11 8 Requins 12 9 Loups 13 9 Chiens Le champs Parent d’une sous-catégorie fait référence à l’identification ID de la catégorie dont elle fait partie. Pour saisir ces données et l’insérer dans une liste (array en anglais) afin de pouvoir l’organiser avec PHP, on fera appel à la fonction suivante:

Index of / Android Login and Registration with PHP, MySQL and SQLite In my previous article Android Login and Registration Screen Design I explained designing the login and registration interfaces. But it has no real time functionality. In this tutorial I am going to explain how to build complete login and registration system in android using PHP, MySQL and SQLite. Also this tutorial covers how to build simple API using PHP and MySQL. Below are the final outputs of this project. Prerequisites This tutorial is combination of few of my previous articles. 1. 2. API (Application Programming Interface) To interact with MySQL database we need to build a REST API first. ⇒ Accepts requests in GET/POST methods⇒ Interact with database by inserting / fetching data.⇒ Finally will give response back in JSON format 1. Download & Install WAMP server from www.wampserver.com/en/. You can test your server by opening the address in your browser.

Connection between PHP (server) and Android (client) Using HTTP and JSON « Fahmi Rahman The main reason for taking a scripting language like PHP is because of the interaction with databases it can offer. In this tutorial I will show you how to use PHP and the MySQL database to retrieve information from the server. For making connection to PHP script, we will use HTTP protocol from the android system. To implement this tutorial you should have basic knowledge of how to run PHP script and start server. If we talk about client-server architecture, client is Android device and in server side there is a combination of PHP Script and MySQL. Android - PHP - MySQL Scheme We will use JSON (JavaScript Object Notation) format. How json will be used in our application. – When android application will execute, it will connect android device to PHP Script. – PHP Script will fetch data from the database. Here is the implementation detail. We want to retrieve food name from our table FOOD that starts with A. For example we will have this functionality in food.php: – JSON Code: – Class code:
