It is designed to get customers up and running quickly and describes how to compile and run a DPDK application in a FreeBSD application (bsdapp) environment, without going deeply into detail. For a comprehensive guide to installing and using FreeBSD, the following handbook is available from the FreeBSD Documentation Project: FreeBSD Handbook. Note: The DPDK is now available as part of the FreeBSD ports collection. Installing via the ports collection infrastructure is now the recommended way to install the DPDK on FreeBSD, and is documented in the next chapter, Installing DPDK from the Ports Collection. -

It helps me to remember what I have gone through while finding new games. The biggest reason to read or at least skim this document is because how can you search for something you do not know exists? I will show you ways to play games, what free and non-free games are available, and give links to help you get started on downloading them. -

Introduction to Unix
Introduction to Unix AfNOG 2007 Workshop April 22, 2007 - Abuja, Nigeria Hervey Allen Phil Regnauld What©s Our Goal? ● To introduce basic UNIX concepts ● To present FreeBSD, a UNIX flavor ● To practice some of the concepts with exercises. ● To give you the fundamental concepts and practice needed in UNIX to be able to concentrate on what©s being taught during the week. Some Practical Matters ● Please do not change the root password. ● Please do ask questions! Lots of questions! Really -we mean this. ● If you don©t understand something be sure you ask for help! This is how you learn. ● Questions? Simplified Unix family tree (Look at the wall... :-)) AT&T 4.4BSD System V BSDI $ Solaris $ Linux Red Hat (rpm) $ NetBSD mandrake FreeBSD SuSE OpenBSD yellowdog etc debian (apt) gentoo (portage) others... General Concepts The Kernel ● Either monolithic or microkernel ● Takes care of managing resources and running processes in a fair way as well as enforcing rights and privileges ● Multiple programs (processes) can run concurrently thanks to the kernel ● Resource management includes: peripherals, memory, disk, network, CPU ● RAM + disk = virtual memory ± kernel oversees memory access The Filesystem ● The file system is a tree. Objects include files, directories (folders), links, devices ● In UNIX, Everything Is A File! (well, almost) ● Files can be accessed via an explicit path, from the root, to the file: ● /usr/local/bin/bash -> this is an ABSOLUTE path ● ... or in relation to where one is located: ● ../../etc/passwd -> this is a RELATIVE path -

Hassling with the IDE - for Haskell
Hassling with the IDE - for Haskell This guide is for students that are new to the Haskell language and are in need for a proper Integrated Development Environment (IDE) to work on the projects of the course. This guide is intended for Windows users. It may work similarly on Linux and iOS. For more information, see: - https://www.haskell.org/platform/mac.html for iOS - https://www.haskell.org/downloads/linux/ for Linux For any errors, please contact me at [email protected]. Changelog 04/09/2019 Initial version 24/08/2020 Updated contents for the year 2020 / 2021, thanks to Bernadet for pointing it out 1. Installing Visual Studio Code Visual Studio Code (VSC) is a lightweight, but rather extensive, code editor. We’ll talk about its features throughout this guide. You can download VSC at: https://code.visualstudio.com/download Once installed, take note of the sidebar on the left. From top to bottom, it contains: - Explorer (Ctrl + Shift + E) - Search (Ctrl + Shift + F) - Source control (Ctrl + Shift + G) - Debug (Ctrl + Shift + D) - Extensions (Ctrl + Shift + X) The bold options are important to remember. They will be mentioned throughout this document. 2. Installing GHC (and stack / cabal) on Windows Download the Glasgow Haskell Compiler (GHC). This compiler is used throughout this course and any other course that uses Haskell. You can find its download instructions at: https://www.haskell.org/platform/windows.html The download link recommends you to use Chocolatey. Chocolatey is an open source project that provides developers and admins alike a better way to manage Windows software. -

Bulk Ports Management with Poudriere
1 of 3 Bulk Ports Management with Poudriere BY DREW GURKOWSKI Step 1: Using the Ports Collection to Install Poudriere All commands in this section should be run as root; using the su(1) command will work. To download a compressed snapshot of the Ports Collection into /var/db/portsnap: # portsnap fetch When running portsnap for the first time, extract the snapshot into/usr/ports : # portsnap extract Next, build and install Poudriere from the Ports Collection using: # cd /usr/ports/ports-mgmt/poudriere # make install clean Prompts will appear throughout the installation process, stick with the default settings and in- stall the port. Step 2: Configuring Poudriere Poudriere is an extremely powerful tool designed for package production, but it can also be used to bulk manage ports. In order to do so, a few small tweaks will need to be made to the configuration before moving forward. First, copy and move the configuration file to the correct location with: # cd /usr/local/etc # cp poudriere.conf.sample poudriere conf Then use the ee(1) text editor to edit the copied configuration file: # ee poudriere.conf Arrow keys can be used to navigate down to the line: FREEBSD_HOST=_PROTO_://_CHANGE_THIS_ Edit the above line, so it instead looks like this: (backspace to delete text) FREEBSD_HOST=ftp://ftp.freebsd.org Type ESCAPE and then ENTER twice to exit and save changes to the configuration file. FreeBSD Journal • May/June 2020 35 2 of 3 Step 3: Set Up a Poudriere Jail Before continuing, Poudriere will need to fetch and extract its own version of the FreeBSD Ports Collection.
