Regular expressions training course description Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Python and MySQL. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them. What will you learn Use Regular Expressions. Troubleshoot Regular Expressions. Compare RE features among different versions. Explain how the regular expression engine works. Optimize REs. Match what you want, not what you don't want. Regular expressions training course details Who will benefit: Anyone looking to use regular expressions. Prerequisites: None. Duration 1 day Regular expressions training course contents Introduction to Regular Expressions Solving real problems, REs as a language, the filename analogy, language analogy, RE frame of mind, searching text files: egrep, egrep metacharacters, start and end of the line, character classes, matching any character with dot, alternation, ignoring differences in capitalization, word boundaries, optional items, other quantifiers: repetition, parentheses and backreferences, the great escape, expanding the foundation, linguistic diversification, the goal of a RE, more examples, RE nomenclature, Improving on the status quo. Extended introductory examples A short introduction to Perl, matching text with regular expressions, toward a more real-world example, side effects of a successful match, Intertwined regular expression, intermission, modifying text with regular expressions, example: form letter, example: prettifying a stock price, automated editing, a small mail utility, adding commas to a number with lookaround, text-to-HTML conversion, that doubled-word thing. Regular expression features and flavours The regex landscape, origins of REs, care and handling of REs, Integrated handling, procedural and object-oriented handling, search-and-replace example. strings character encodings and modes, strings as REs, character-encoding issues, unicode, regex modes and match modes, common metacharacters and features, character representations, character classes and class-like constructs, anchors and other 'zero-width assertions', comments and mode modifiers, grouping capturing conditionals and control. The mechanics of expression processing Two kinds of engines, new standards, regex engine types, from the department of redundancy department, testing the engine type, match basics, about the examples, rule 1: the match that begins earliest wins, engine pieces and parts, rule 2: the standard quantifiers are greedy, regex-directed versus text-directed, NFA engine: regex-directed, DFA engine: text-directed, first thoughts: NFA and DFA in comparison, backtracking, two important points on backtracking, saved states, backtracking and greediness, more about greediness and backtracking, problems of greediness, multi-character 'quotes', lazy quantifiers, greediness and laziness, laziness and backtracking, possessive quantifiers and atomic grouping, possessive quantifiers ?, +, *+, ++ and {m,n}+, the backtracking of lookaround, is alternation greedy? taking advantage of ordered alternation, NFA DFA and posix, the longest-leftmost', posix and the longest-leftmost rule, speed and efficiency. Practical regex techniques Continuation lines, matching an IP address, working with filenames, matching balanced sets of parentheses, watching out for unwanted matches, matching delimited text, knowing your data and making assumptions, stripping leading and trailing whitespace, matching and HTML tag, matching an HTML link, examining an HTTP URL, validating a hostname, plucking a hostname, plucking a URL, parsing CSV files. Crafting an efficient expression Efficiency vs. correctness, localizing greediness, global view of backtracking, more work for POSIX NFA, work required during a non-match, being more specific, alternation can be expensive, benchmarking, know what you re measuring, benchmarking with Python, common optimisations, the mechanics of regex application, pre-application optimizations, optimizations with the transmission, optimization of the regex itself, techniques for faster expressions, common sense techniques, expose literal text, expose anchors, lazy versus greedy: be specific, split into multiple REs, mimic initial-character discrimination, use atomic grouping and possessive quantifiers, lead the engine to a match, unrolling the loop, observations, using atomic grouping and possessive quantifiers, short unrolling examples, unrolling C comments, the free flowing regex, a helping hand to guide the match, a well-guided regex is a fast regex.

Masterclasses? Refreshers? Introductions? It depends what you're looking for and where you want to pitch them, but here are six tried-and-tested highly focused sessions that organisations can take individually or as a series, to help develop their teams' project management capabilities one topic at a time. Objectives for each individual session are set out below, as part of the session outlines. Taken together, as a series, however, these modules are an ideal opportunity to develop your team's levels of project management capability maturity, whether that's by introducing them to the basic principles, refreshing them on best practice, or giving them the opportunity to really drill down into a specific area of challenge in your particular operating environment. Session outlines 1 Stakeholder management Session objectives This session will help participants: Understand why stakeholders matter to projects Be able to identify and engage stakeholders Be able to categorise stakeholders by their significance 1 Key principles What does 'stakeholder' mean - in theory? What does this mean in practice? Why stakeholders matter Consequences of missing stakeholders The stakeholder management process:IdentifyAssessPlanEngage 2 Identifying stakeholders Rapid listing CPIG analysis PESTLE analysis Drawing on the knowledge and experience of others Other ways to identify stakeholders 3 Assessing stakeholders Which stakeholders are significant? Stakeholder radar Power-interest maps Power-attitude maps 4 Planning The adoption curve Dealing with obstacles Who should engage which stakeholder?

How will communication happen? 5 Engaging Seven principles of stakeholder engagement 2 Requirements and prioritisation Session objectives This session will help participants: Understand how clarity of requirements contributes to project success Use different techniques for prioritising requirements Agree requirements with stakeholders Manage changes to requirements 1 Understanding and managing stakeholder needs and expectations What are 'requirements'? What is 'requirements management'? Sources of requirements - and the role of stakeholders Are stakeholders sufficiently expert to specify their needs? Do they understand the detail of what they want, or do they need help to tease that out? What do stakeholders want to achieve? Working within constraints Prioritising requirements - three techniques 2 MoSCoW prioritisation 'Must have', should have', 'could have, 'won't have this time' When to use MoSCoW 3 The Kano Model Customer satisfaction - 'attractive' and 'must-be' qualities When to use Kano 4 Value-based prioritisation Understanding risk v value Using risk v value to prioritise features and schedules 5 Agreeing requirements Perfect v 'good enough' Establishing acceptance criteria Requirements traceability Agreeing project scope 6 Changing requirements Why requirements change Why change control matters Impact on projects A formal change control process Paying for change - managing change for different types of project 3 Estimating Session objectives This session will help participants: Understand the different purposes estimates satisfy Be able to use different estimating techniques Understand how to achieve different levels of accuracy 1 Key principles What's an estimate? Informed guesswork What needs to be estimated? Costs, resources, effort, duration Tolerances Precision v accuracy 2 Estimating through the lifecycle Start Plan Do 3 Early estimates Comparative ('analogous') estimating Parametric estimating Using multiple estimating techniques 4 Bottom-up estimating Bottom-up ('analytical') estimating Pros Cons 5 Three-point estimating Three-point ('PERT': Programme Evaluation and Review Technique) estimating Uncertainty and the range of estimates Calculating a weighted average Three-point with bottom-up 4 Scheduling Session objectives This session will help participants: Understand how to create a viable schedule Be able to use different forms of schedule Understand the concept of the critical path 1 Key principles The planning horizon Rolling wave planning Release planning 2 Viable scheduling Creating a viable schedule Define the scope Sequence the work Identify the risks and build in mitigations Identify the resources Estimate the effort and durations Check resource availability Refine until a workable schedule is produced 3 Critical path analysis The critical path Network diagrams Sequence logic Practical application:Network diagram with estimated durationsThe 'forward pass'The 'backward pass'Calculating total floatIdentifying the critical pathCalculating free float Gantt charts 5 Risk and issue management Session objectives This session will help participants: Understand the difference between risks and issues Be able to identify and assess risks Understand ways of mitigating risks Manage issues 1 Key principles Understanding risk Threats and opportunities The risk management processPreparation - proactive risk managementThe process - identify, assess, plan, implementStakeholder communication Roles and responsibilities Risk management strategy The risk register Risk appetite 2 Risk identification Brainstorming Interviews Assumption analysis Checklists 3 Risk assessment and prioritisation Probability, impact and proximity Triggers Qualitative risk assessment Qualitative impact assessment Qualitative probability assessment Probability / impact grid Bubble charts Risk tolerance 4 Planning countermeasures To mitigate or not to mitigate?

Tolerances Issues and tolerances The PRINCE2 view of issues Ownership of issues An issue management process Issue register 6 Budgeting and cost control Session objectives This session will help participants: Understand what to include in a budget - and why Choose - and use - the appropriate estimating technique Align the budget with the schedule Understand how to monitor spend and control costs Trouble-shoot effectively to get projects back within budget Session format Flexible. The session can be tailored to the participants' average level of project management maturity - a 60-minute session (delivered virtually) is an effective introduction. A 90-minute session allows for more in-depth treatment. A half-day session (face-to-face or virtual) gives time for a more challenging workshop, particularly to discuss specific cost control issues with any of the participants' current projects. 1 Where is the money coming from? Can we pay from revenue? Do we need to borrow? How long will the project take to pay back? The lifecycle of the budget Through-life costs Stakeholder involvement 2 Estimating costs Reminder: the relationship between estimates Reminder: possible estimating techniques What do we need to estimate?PeopleEquipmentMaterialsFacilities and operating costsWork package estimateEstimated project costs Estimating agile projects 3 Aligning budget and schedule Scheduling and financial periods Spreading the budget 4 Reserves and agreeing the budget Contingency reserve Management reserve Agreeing the budget 5 Cost control Planned spend over time Actual spend over time Work completed over time Evaluating different scenarios: delivery v spend 6 Trouble-shooting Why are we where we are? What has caused the project to spend at the rate it is? Why is it delivering at the rate it is? What are the root causes? What can we do about it?
