Beyond Relational Databases
EXPERT ANALYSIS BY MARCOS ALBE, SUPPORT ENGINEER, PERCONA Beyond Relational Databases: A Focus on Redis, MongoDB, and ClickHouse Many of us use and love relational databases… until we try and use them for purposes which aren’t their strong point. Queues, caches, catalogs, unstructured data, counters, and many other use cases, can be solved with relational databases, but are better served by alternative options. In this expert analysis, we examine the goals, pros and cons, and the good and bad use cases of the most popular alternatives on the market, and look into some modern open source implementations. Beyond Relational Databases Developers frequently choose the backend store for the applications they produce. Amidst dozens of options, buzzwords, industry preferences, and vendor offers, it’s not always easy to make the right choice… Even with a map! !# O# d# "# a# `# @R*7-# @94FA6)6 =F(*I-76#A4+)74/*2(:# ( JA$:+49>)# &-)6+16F-# (M#@E61>-#W6e6# &6EH#;)7-6<+# &6EH# J(7)(:X(78+# !"#$%&'( S-76I6)6#'4+)-:-7# A((E-N# ##@E61>-#;E678# ;)762(# .01.%2%+'.('.$%,3( @E61>-#;(F7# D((9F-#=F(*I## =(:c*-:)U@E61>-#W6e6# @F2+16F-# G*/(F-# @Q;# $%&## @R*7-## A6)6S(77-:)U@E61>-#@E-N# K4E-F4:-A%# A6)6E7(1# %49$:+49>)+# @E61>-#'*1-:-# @E61>-#;6<R6# L&H# A6)6#'68-# $%&#@:6F521+#M(7#@E61>-#;E678# .761F-#;)7-6<#LNEF(7-7# S-76I6)6#=F(*I# A6)6/7418+# @ !"#$%&'( ;H=JO# ;(\X67-#@D# M(7#J6I((E# .761F-#%49#A6)6#=F(*I# @ )*&+',"-.%/( S$%=.#;)7-6<%6+-# =F(*I-76# LF6+21+-671># ;G';)7-6<# LF6+21#[(*:I# @E61>-#;"# @E61>-#;)(7<# H618+E61-# *&'+,"#$%&'$#( .761F-#%49#A6)6#@EEF46:1-# -

XAMPP Web Development Stack
XAMPP Web Development Stack Overview @author R.L. Martinez, Ph.D. The steps below outline the processes for installing the XAMPP stack on a local machine. The XAMPP (pronounced Zamp) stack includes the following: Apache HTTP Server, MariaDB (essentially MySQL), Database Server, Perl, and the PHP Interpreter. The “X” in XAMPP is used to signify the cross-platform compatibility of the stack. The Apache HTTP Server and PHP are required to run phpMyAdmin which is a PHP application that is used for database administration tasks such as creating databases and tables, adding users, etc. Alternative to XAMPP If you have experience with MySQL Workbench, you may prefer to install MySQL Server and MySQL Workbench via the MySQL Installer. MySQL Workbench performs the same functions as phpMyAdmin. However, unlike phpMyAdmin which is a web-based application, MySQL Workbench is a locally installed application and therefore does not require an HTTP Server (e.g. Apache) to run. Installing XAMPP Many of the steps listed have several alternatives (such as changing MySQL passwords via a command line) and students are welcomed and encouraged to explore alternatives. 1. Download XAMPP from the URL below and place the installer (.exe) in the location where you want to install XAMPP. Placing the installer (.exe) in the same location as the intended installation is not required but preferred. http://www.apachefriends.org/download.html Page 1 of 17 XAMPP Web Development Stack 2. See the warning which recommends not installing to C:\Program Files (x86) which can be restricted by UAC (User Account Control). In the steps below XAMPP is installed to a USB flash drive for portability. -
Mariadb Presentation
THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it. -
The Role of Social Media in Public Relations Practice – a New Zealand Perspective
The Role of Social Media in Public Relations Practice – a New Zealand Perspective Stefanie Martens A thesis submitted to Auckland University of Technology in partial fulfilment of the requirements for the degree of Master of Communication Studies (MCS) 2020 School of Communications Studies Faculty of Design and Creative Technologies ABSTRACT This study investigates the trends in the use of social media in the practice of New Zealand public relations and sheds light on how New Zealand public relations professionals evaluate the role of social media in their profession. It followed a triangulation approach by combining a document analysis of 148 award- winning communication campaigns and in-depth semi-structured interviews with ten New Zealand public relations practitioners. The findings show that New Zealand public relations practitioners have not significantly changed the ways they have adopted and used social media over the last decade. Practitioners still seem to focus their efforts on established social media platforms and refrain from adopting new ones. Their adoption of new social media platforms appears to follow fashion trends; for example, applications like Instagram and Instagram Stories were adopted quicker than others. In-house practitioners also seem to generally lag when adopting social media platforms due to a control paradigm that is still prevalent within organisations. Return on investment and resource restrictions are identified as important influencing factors on the practitioners’ application of social media platforms. The practitioners appear to concentrate their social media efforts on a selected number of most popular platforms that offer more advantages, such as reach. The results of this study suggest that practitioners are using social media more strategically than in the past. -

Artificial Intelligence for Understanding Large and Complex
Artificial Intelligence for Understanding Large and Complex Datacenters by Pengfei Zheng Department of Computer Science Duke University Date: Approved: Benjamin C. Lee, Advisor Bruce M. Maggs Jeffrey S. Chase Jun Yang Dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the Graduate School of Duke University 2020 Abstract Artificial Intelligence for Understanding Large and Complex Datacenters by Pengfei Zheng Department of Computer Science Duke University Date: Approved: Benjamin C. Lee, Advisor Bruce M. Maggs Jeffrey S. Chase Jun Yang An abstract of a dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the Graduate School of Duke University 2020 Copyright © 2020 by Pengfei Zheng All rights reserved except the rights granted by the Creative Commons Attribution-Noncommercial Licence Abstract As the democratization of global-scale web applications and cloud computing, under- standing the performance of a live production datacenter becomes a prerequisite for making strategic decisions related to datacenter design and optimization. Advances in monitoring, tracing, and profiling large, complex systems provide rich datasets and establish a rigorous foundation for performance understanding and reasoning. But the sheer volume and complexity of collected data challenges existing techniques, which rely heavily on human intervention, expert knowledge, and simple statistics. In this dissertation, we address this challenge using artificial intelligence and make the case for two important problems, datacenter performance diagnosis and datacenter workload characterization. The first thrust of this dissertation is the use of statistical causal inference and Bayesian probabilistic model for datacenter straggler diagnosis. -
