Using the Parallel Computing capabilities in MATLAB allows you to take advantage of additional hardware resources that may be available either locally on your desktop or on clusters and clouds. By using more hardware, you can reduce the cycle time for your workflow and solve computationally- and data-intensive problems faster.
In this seminar, we will discuss a range of workflows available to scale MATLAB applications with minimal changes to your MATLAB code and without needing to learn any shell or scheduler programming syntax.
This is an introduction to programming in modern C++, based on the book "'Programming: Principles and Practice using C++"' (2nd ed.) by Bjarne Stroustrup. The aim is to teach participants how to write non trivial, practical programs that are comprehensible and portable. Participants should also be able to understand and modify most well-written C++ applications, though not necessarily every aspect of them.
C++ is a large and complicated language, which is reflected in the length of this course. The creator of C++, Prof. Stroustrup, estimates that newcomers to programming will have to devote in excess of 200 hours' of work to learn how to program in C++ properly. Please bear that in mind if signing up for the course. It would also be of help (though not essential) if attendees have some prior programming experience in another language, e.g. Python.

CCNA Routing and Switching provides a comprehensive overview of networking concepts and skills, from network applications to the protocols and services provided to those applications by the lower layers of the network, with an emphasis on practical application, work-force readiness, and soft-skills development. You will progress from basic networking to more complex enterprise and theoretical networking models later in the curriculum.
There are four modules in the recommended sequence:
We offer this program as instructor led with online access to the curriculum with the support of interactive media and an online networks laboratory called NETLAB. There is a mix of lecture, demonstrations and a heavy emphasis on practical activities using live lab equipment and a simulation package.
Introduction to Networks is the first module of four modules in CCNA. Please book onto this first module to reserve your place for the whole programme.
This module introduces the architecture, structure, functions, components, and models of the Internet and computer networks. The principles of IP addressing and fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the curriculum. By the end of the course, you will be able to build simple LANs, perform basic configurations for routers and switches, and implement IP addressing schemes.
This is the third module of the CCNA series, should you wish to book on the series please book on Module 1 Introduction to Networks.
This course describes the architecture, components, and operations of routers and switches in a large and complex network. You will learn how to configure routers and switches for advanced functionality. By the end of this course, you will be able to configure and troubleshoot routers and switches and resolve common issues with OSPF, EIGRP, STP, and VTP in both IPv4 and IPv6 networks. You will also develop the knowledge and skills needed to implement DHCP and DNS operations in a network.
This is the fourth module of the CCNA series, should you wish to book on the series please book on Module 1 Introduction to Networks.
This course discusses the WAN technologies and network services required by converged applications in a complex network. The course enables you to understand the selection criteria of network devices and WAN technologies to meet network requirements. You will learn how to configure and troubleshoot network devices and resolve common issues with data link protocols.

This PHP introduction course explores the basic elements of PHP script programming. PHP allows web developers to write dynamic web pages, for instance by simplifying ways to collect data through a web form, and to process and include data, by placing small scripts directly into HTML files.
Session 1 will provide background, tools and exercises for writing and editing PHP in HTML files, uploading them to a web server, and making them available online. There will also be an introduction to programming in PHP, to help enable you to later adapt the examples to address your more advanced examples and projects.
Session 2 will extend the simpler exercises in Session 1, adding more options and capabilities, as well as providing new and more advanced examples. Using the tools and techniques from Session 1, there will be opportunities to adjust and partly customise the examples, and if time permits potentially begin a small exercise of your own.
This course is part of the Scientific Computing series.
This course is aimed at those new to programming, or who have never been formally taught the principles and basic concepts of programming. It provides an introduction to the basic concepts common to most high level languages (including Python, Java, Fortran, C, C++, Visual Basic). The aim of the course is to equip attendees with the background knowledge and confidence necessary to tackle many on-line and printed programming tutorials. It may also help attendees in deciding which programming language is suitable for their programming task.
Knowledge of the concepts presented in this course is a pre-requisite for many of the other courses in the Scientific Computing series of courses (although not for the "Python for Absolute Beginners" course).
This course is part of the Scientific Computing series and is suitable for people who have Python experience equivalent to either of the introductory courses: Introduction for Absolute Beginners or Introduction for Programmers
These sessions consist of a selection of self-paced mini-courses, each taking at most a half-day. Python expert(s) from the UCS will be present to answer questions or address difficulties with these. Attendees can select from the available topics to most closely meet their individual needs. Attendees are welcome to attend more than one session to work through multiple topics. If an attendee finishes a topic with time to spare they may select another, and so on.
This course is part of the Scientific Computing series.
This course is aimed at those new to programming and provides an introduction to programming using Python, focussing on scientific programming. This course is probably unsuitable for those with programming experience, even if it is just in shell scripting or Matlab-like programs. By the end of this course, attendees should be able to write simple Python programs and to understand more complex Python programs written by others.
As this course is part of the Scientific Computing series, the examples chosen are of most relevance to scientific programming.
This course is part of the Scientific Computing series.
This full-day course introduces the Python programming language to those who are already familiar with another high level programing language such as C/C++, Fortran, Java, Perl or Visual Basic. The aim of this course is to give such programmers sufficient familiarity with Python that they can attend any of the more advanced Python courses organised by the Computing service and easily follow any of the widely available Python tutorials on the more complex aspects of the language.
This course covers all the material contained in the "Programming: Python for Absolute Beginners" course, but in a more abbreviated fashion suitable for those who already have significant programming experience. This course does NOT cover the more complex aspects of the language (for such topics see the other Computing Service Python courses), nor is there much explicit discussion of the object oriented features of Python.
If you are an accomplished and experienced programmer you may find this course too slow, you may prefer to self-teach the course rather than attend in person, the full set of notes can be downloaded.
This course gives a simple introduction to organizing your data in a relational database. It aims to explain the arranging of your data. It does not deal with specific relational databases systems such as Access, Oracle or SQL Server, or the technical tools that you would or could use to set up your database. The course aims to provide you with enough information to sit down and design your database, regardless of the database product that you intend to use. Exercises will be done on paper, without using computers.

Handling the large volume of spam, ransomware and other malware delivered via email to often indignant users has become quite a large part of standard IT duties over the past few years. Along with the increasing complexity of the tricks and techniques used by hacker groups for spearphishing and delivering malware, it is clearly apparent that there is only so much that professional IT staff can expect from their users in terms of determining what is, and is not, malware or phishing.
Yet the pressure on often relatively junior administrative and financial staff has not decreased and the time taken to try and work out what is genuine and what is not does not make for smooth time management. Most important of all, IT practitioners must not indulge in the blame culture when an incident happens, simply because the person blamed will probably never "own up" to making a possible mistake again. A positive culture - even admitting "Yes, it has happened to me" - is essential to encourage users to be open about mistakes.
This seminar will attempt to show some of the more common of the latest spammer tricks, and introduce some tools which (hopefully) will make your life easier.
