Shutdown Script for Retropie
Shutdown Script for Retropie Use pin number 5 & 14 for “Shutdown” 1. Update RetroPie: • sudo apt-get update 2. Upgrade RetroPie • sudo apt-get upgrade 3. Install Python • sudo apt-get install python-dev • sudo apt-get install python3-dev • sudo apt-get install gcc • sudo apt-get install python-pip 4. Next you need to get RPi.GPIO: • wget https://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.5.11.tar.gz 5. Extract the packages: • sudo tar -zxvf RPi.GPIO-0.5.11.tar.gz 6. Move into the newly created directory: • cd RPi.GPIO-0.5.11 • 7. Install the module by doing: • sudo python setup.py install • sudo python3 setup.py install 8. Creating a directory to hold your scripts: • mkdir /home/pi/scripts 9. Call our script shutdown.py (it is written in python). Create and edit the script by doing: • sudo nano /home/pi/scripts/shutdown.py The content of the script: Paste it in the blank area #!/usr/bin/python import RPi.GPIO as GPIO import time import subprocess # we will use the pin numbering to match the pins on the Pi, instead of the # GPIO pin outs (makes it easier to keep track of things) GPIO.setmode(GPIO.BOARD) # use the same pin that is used for the reset button (one button to rule them all!) GPIO.setup(5, GPIO.IN, pull_up_down = GPIO.PUD_UP) oldButtonState1 = True while True: #grab the current button state buttonState1 = GPIO.input(5) # check to see if button has been pushed if buttonState1 != oldButtonState1 and buttonState1 == False: subprocess.call("shutdown -h now", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE) oldButtonState1 = buttonState1 time.sleep(.1) Press CRTL X Then Y and Enter 10. -

Top 15 ERP Software Vendors – 2010
Top 15 ERP Software Vendors – 2010 Profiles of the Leading ERP Vendors Find the best ERP system for your company. For more information visit Business-Software.com/ERP. About ERP Software Enterprise resource planning (ERP) is not a new concept. It was introduced more than 40 years ago, when the first ERP system was created to improve inventory control and management at manufacturing firms. Throughout the 70’s and 80’s, as the number of companies deploying ERP increased, its scope expanded quite a bit to include various production and materials management functions, although it was designed primarily for use in manufacturing plants. In the 1990’s, vendors came to realize that other types of business could benefit from ERP, and that in order for a business to achieve true organizational efficiency, it needed to link all its internal business processes in a cohesive and coordinated way. As a result, ERP was transformed into a broad-reaching environment that encompassed all activities across the back office of a company. What is ERP? An ERP system combines methodologies with software and hardware components to integrate numerous critical back-office functions across a company. Made up of a series of “modules”, or applications that are seamlessly linked together through a common database, an ERP system enables various departments or operating units such as Accounting and Finance, Human Resources, Production, and Fulfillment and Distribution to coordinate activities, share information, and collaborate. Key Benefits for Your Company ERP systems are designed to enhance all aspects of key operations across a company’s entire back-office – from planning through execution, management, and control. -

More to do Introduction For a beginner to the world of raspberry pi, there are a number of projects that can become the start of something big. In this article, I discuss such a simple project which is adding a button that can be used to shutdown the raspberry pi using a bit of software tinkering. I wrote a similar article in 2013 at my blog “embeddedcode.wordpress.com” and its got its share of attention since a lot of people starting out with a single board computer, kept looking for a power button. Additionally, those who wanted a headless system, needed a way to shutdown the computer without the mess of connecting to it over the network or attaching a monitor and keyboard to it. In this article, I revisit the tutorial on how to add a shutdown button while trying to explain the workings and perhaps beginners will find it an amusing to add find more things to do with this little recipe. What do you need? Here is a basic bill of materials required for this exercise. -

Shutdown policies with power capping for large scale computing systems Anne Benoit1, Laurent Lef`evre1, Anne-C´ecileOrgerie2, and Issam Ra¨ıs1 1 Univ. Lyon, Inria, CNRS, ENS de Lyon, Univ. Claude-Bernard Lyon 1, LIP 2 CNRS, IRISA, Rennes, France Abstract Large scale distributed systems are expected to consume huge amounts of energy. To solve this issue, shutdown policies constitute an appealing approach able to dynamically adapt the resource set to the actual workload. However, multiple constraints have to be taken into account for such policies to be applied on real infrastructures, in partic- ular the time and energy cost of shutting down and waking up nodes, and power capping to avoid disruption of the system. -

Don't Trust Traceroute (Completely)
Don’t Trust Traceroute (Completely) Pietro Marchetta, Valerio Persico, Ethan Katz-Bassett Antonio Pescapé University of Southern California, CA, USA University of Napoli Federico II, Italy [email protected] {pietro.marchetta,valerio.persico,pescape}@unina.it ABSTRACT In this work, we propose a methodology based on the alias resolu- tion process to demonstrate that the IP level view of the route pro- vided by traceroute may be a poor representation of the real router- level route followed by the traffic. More precisely, we show how the traceroute output can lead one to (i) inaccurately reconstruct the route by overestimating the load balancers along the paths toward the destination and (ii) erroneously infer routing changes. Categories and Subject Descriptors C.2.1 [Computer-communication networks]: Network Architec- ture and Design—Network topology (a) Traceroute reports two addresses at the 8-th hop. The common interpretation is that the 7-th hop is splitting the traffic along two Keywords different forwarding paths (case 1); another explanation is that the 8- th hop is an RFC compliant router using multiple interfaces to reply Internet topology; Traceroute; IP alias resolution; IP to Router to the source (case 2). mapping 1 1. INTRODUCTION 0.8 Operators and researchers rely on traceroute to measure routes and they assume that, if traceroute returns different IPs at a given 0.6 hop, it indicates different paths. However, this is not always the case. Although state-of-the-art implementations of traceroute al- 0.4 low to trace all the paths -
