Beyond PowerPoint & Keynote: The 20 Best Apps to Create and Share Presentations - The Zapier Blog. From school classrooms to Apple product launches, slideshow presentations have quickly become the standard accompaniment to lectures. You can't give a speech without a slideshow, it seems. And they all feel same. Presentations are dominated by Microsoft PowerPoint and Apple Keynote, apps that are all but omnipresent. There are good reasons they're so popular: PowerPoint and Keynote come packaged with Microsoft Office and new Macs, respectively, and they've been around for a long time. They're also full of valuable features, from dozens of slide templates to a variety of polished transitions.

But knowing how to take advantage of all they offer gets so complicated that there are entire books and courses about them. Making a delightful and well-designed presentation shouldn't be so hard. What Makes a Great Presentation App? There are times that call for a beautifully crafted presentation.

Typepick Myth Gridless. Control your Arduino board with Raspberry Pi and Python. Introduction An Arduino board can communicate with the Raspberry Pi via a serial over USB connection. This creates a virtual serial interface, which it uses like a normal interface, reading and writing to the serial device file. To begin, attach your Arduino board and type: $dmesg | tail [..]usb 1-1.2: Manufacturer: Arduino[..][..]cdc_acm 1-1.2:1.0: ttyACM0: USB ACM device[..]

My Arduino Uno board device is /dev/ttyACM0 and its driver is cdc_acm. Old arduino boards with a FTDI USB-Serial chip are accessed via /dev/ttyUSB*: $ls -l /dev/ttyACM* crw-rw---T 1 root dialout 166, 0 Nov 5 00:09 /dev/ttyACM0 Ok, now you should add your user to the ‘dialout’ group to give the required read/write access, then logout and login again for this to take effect: $sudo usermod -a -G dialout YOURUSERNAME This is important because Nanpy works using this device file. $sudo apt-get install arduino from nanpy import ArduinoArduino.pinMode(13, Arduino.OUTPUT)Arduino.digitalWrite(13, Arduino.HIGH) The external world. Raspberry Pi + Arduino + Tornadoniltoid. Tornado is a great open source, Python based web framework. It is designed to be light-weight, easily scalable, non-blocking and it supports websockets and some other nice features.

What’s more, it runs smooth and quick on the Raspberry Pi. Thus far, my experiments with the Raspberry Pi have involved running Node.js on it to serve web pages and to interact over serial with an Arduino. Here are some posts on how to do that: 1. I wanted to try accomplishing something similar using Python. Tornado Setup First things first, install Tornado on your Raspberry Pi: 1. 2. 3. 4. 5. 6. 7. To make sure everything works, create a file named “server.py” containing the following code (taken from Tornado’s site), and run it from terminal using the command “python server.py” Now on a separate computer on the same network, navigate your browser to (or use the IP address for example 192.168.1.7:8080).

Adding Websockets Adding websockets to your Tornado app is easy. 1. Tutorial: Raspberry Pi GPIO Pins and Python. The GPIO pins on a Raspberry Pi are a great way to interface physical devices like buttons and LEDs with the little Linux processor. If you’re a Python developer, there’s a sweet library called RPi.GPIO that handles interfacing with the pins. In just three lines of code, you can get an LED blinking on one of the GPIO pins. Not sure if Raspberry Pi is right for you? Make:’s interactive Board Guide lets you dial into the field to find the best board for your needs. Installation The newest version of Raspbian has the RPi.GPIO library pre-installed. Using the RPi.GPIO Library Now that you’ve got the package installed and updated, let’s take a look at some of the functions that come with it.

Sudo python myInputSketch.py All of the following code can be added to this same file. To add the GPIO library to a Python sketch, you must first import it: import RPi.GPIO as GPIO Then we need to declare the type of numbering system we’re going to use for our pins: from Meltwater’s Raspberry Pi Hardware.

Raspberry Pi | The lost outpost. Before you dismiss this as TL;DR – it’s a subject dear to my heart, and I believe that there’s some cool content as well as some storytelling – do give it a chance! A sad state of affairs I believe that we have lived through the best period to teach and learn about computers and technology, and that over the past few years we have been creating a void, a vacuum, in which progress may be diminished. Google’s Eric Schmidt recently called out the British education system as holding back or dismissing our technology heritage. According to a ZDNet article on his speech in Edinburgh: Schmidt said the UK’s approach to technology in education — not making IT compulsory as a subject at the GSCE-level and not providing enough support for science students at colleges — meant the country was “throwing away” its computing heritage.

Olis2cents - Arch Linux as a Webserver. In this tutorial, I briefly explain how to set up a webserver using nginx, openssl and uwsgi on Arch Linux. The tutorial is applicable to other Linux distributions and goes through the required configuration step by step. It is, I believe, beginner friendly. Arch Linux is an amazing Linux distribution. Among other great things, it is extremely lightweight, ships with pacman, the best package manager I have seen so far, and has a great wiki with all you need to know to get it up and running. After having used Arch on my laptop and desktop machine at work for a couple of years now, I decided to give it a try running on my webserver.

Although written for Arch, this tutorial is in general applicable to any Linux distribution. 1.1 Attention! One important thing must be said first. In the (almost) ten months that I have been running Arch as a server, I experienced only a few critical problems and all of them could be fixed quickly. 1.2 Non-Arch distributions on Arch, but you would need to run.

MarkWiki - Home. Raspberry Pi. Port mirroring sous Linux avec iptables | Application (Linux) I. Introduction Dans ce tutoriel, nous allons voir comment mettre en place un port mirroring sous Linux en utilisant l’outil de gestion du pare-feu netfilter : iptables. Pour ma part, j’effectue ce tutoriel sur une Debian 7 avec la version 1.4.14 d’iptables. II. Pour bien comprendre la procédure que nous allons effectuer, il est important de comprendre ce qu’est le port mirroring et comment il fonctionne. Note : il ne faut pas confondre redirection et port mirroring, la redirection va changer le destinataire final du paquet alors que le port mirroring va dupliquer le trafic pour qu’il soit reçu par d’autres hôtes et non pas que par le destinataire initial. Pour illustrer le fonctionne du port mirroring, prenons ce schéma : Ici, le port 2 du switch sur lequel est le PC 2 est appelé le “port mirroré”, cela signifie que tout ce qui arrive ou sort de ce port (donc qui va vers ou vient du PC 2) sera dupliqué vers le port 3 du switch donc vers le PC 3.

III. IV. 32 static website generators for your site, blog or wiki. Select a Language. Help What is repl.it? It is an online environment for interactively exploring programming languages. The name comes from the read-eval-print loop, the interactive toplevel used by languages like Lisp and Python. How do I start? Once you have selected a language, start by typing an expression into the console on the right side of the screen and pressing Enter. Can I use variables or other state? Yes! Can I save my session?

Pancake. Using Django and MongoDB to Build a Blog. This article shows how to create a simple blog site using the MongoDB Document Database and the Django Web framework. Mongo Basics MongoDB is an open-source document-oriented database, not a traditional relational database, written in C++ by Dwight Merriman and Eliot Horowitz. Being a document database does not mean storing Microsoft Word documents, but rather it means storing semi-structured data. You can input arbitrary binary JSON objects (BSON) into a MongoDB database. It runs on UNIX machines as well as Windows and supports replication and sharding.

Your Linux distribution probably includes a MongoDB package, so go ahead an install it if you have not done so already. On a Debian 7 system, you can install MongoDB with the following command: # apt-get install mongodb After installing MongoDB, start the MongoDB server process with: # service mongodb start Similarly, you can stop the running MongoDB server with: # service mongodb stop The configuration file for MongoDB is /etc/mongodb.conf. Getting Started with Bootstrap 3. Despite labeling myself a backend developer, I’ve been dabbling more and more with front-end design, namely because JavaScript has blurred the lines between the two. On my last project I hacked a bit with HTML and CSS to develop responsive styles – which can be a pain. Thankfully, frameworks such as Bootstrap (formerly known as Twitter Bootstrap) make such design requests fairly simple – and even simpler with the new release of Bootstrap 3. Let’s take a look. This is a 3-part series.

In the first part, we’ll only be looking at Bootstrap 3 and how to customize it using HTML and CSS. In the second part, we’ll look at how to set up an effective sales landing page. Check it out here. You can grab the final styles/pages from this repo. Create a minimal layout Start by downloading Bootstrap from the official site. Add an index.html file with the following content: Add a nav bar (which is now ALWAYS responsive), a container, Jumbotron, some ipsum text, and a button: Grid System Test that out. Good?

Securing your Raspberry PI with SSL and Simple Authentication | PRATERMADE. Many of the home automation projects that I’ll be talking about on this blog will be controllable with a web browser. Most of the projects will, in fact, be controlled with simple HTTP GET requests. I do this to make it as easy as possible to control with as many methods as possible. In future postings, you will see that I will be able to control things with actions as simple as visiting a book mark, executing a Tasker task, accessing an Android Applications, or even using a nice Ajax’y web dashboard.

The problem with using this internet accessible approach is that is is inherently insecure. Prerequisites These instructions assume that you have a Raspberry Pi with the Raspbian, Nginx, Flask, and uWSGI installed and working. Internal network You were advised to only do the garage door opener project with the Raspberry Pi on an internal secure network.

Considering all of that, and if you want to access your controls from external networks, you should take some additional steps. Using SSL. Personnalisez votre shell.
