Data structures for Text Editors: Hakim Cassimally @osfameron Lambda Lounge Manchester, Mon 16th Jan 2017 There are some notes in the tab below on SlideShare. Alternatively, you can download a PDF with full notes from https://www.dropbox.com/s/gxi2zbb861f82vw/text-editors-with-notes.pdf?dl=0 I don't normally draw slides, but this time I started to get grumpy about drawing boxes in Keynote and decided it would actually be easier to use pen and paper. I'm not sure if the result looks good, but it kept me amused and was mostly fun (taking photos of the resulting thing was a bit of a faff.) LambdaLounge is a meetup for functional programmers, and this talk has a focus on immutable data-structures. There are few code examples (it turns out that one (dis?)advantage of drawing slides is that you don't really feel like writing out large chunks of source code) but what little there is is in Clojure.

From session at http://www.lambdalounge.org.uk/ on 18th April 2016. Here's the original blurb: So, Haskell is "an advanced purely-functional programming language" which supports writing "declarative, statically typed code". It may be optimized for academic buzzwords you've never heard of but... is it any good for writing code in the way that you'd write Perl, Python, or Ruby? What are strong types, and why are we so frightened of them anyway? Can you develop interactively in Haskell, the way you would in a dynamic language? Does Haskell have "whipuptitude" (being able to get things done quickly) as well as "manipulexity" (being able to manipulate complex things)? And perhaps most importantly, can writing Haskell be *fun*? Haskell is founded on decades of the finest mathematical and computer science research. Perl, quite demonstrably isn't... but why do so many Perl programmers also love Haskell? Audrey Tang wrote the first prototype for Perl 6, Pugs, in Haskell, and coined the phrase "lambdacamel" for the substantial crossover between the languages. What does a Perl programmer make of Haskell? What are the lessons that can be learned (in either direction). And do the languages have more in common than you might have thought?

Is Haskell an acceptable Perl?

My proposal for northwestengland.pm's Hackday. Oyster will be an opensource set of tools and modules to enable easy provisioning and deployment of Perl web-apps to the cloud. Oyster was selected as the main application for the Hackday on 20th December. During the day we'll also be working on Iain's "Hackday in a Box" application (which will be the first test application for Oyster!); triaging Perl bugs; and adding features to last year's project Ironman. Why Aim So Low indeed!

Unix has always had a philosophy of composable tools, where one tool outputs to the next in a pipeline. But the technique of piping a *textual* stream of data, and having to extract data out of it is looking a bit long in the tooth. Microsoft (not historically an innovator in its shell environment :-) has stolen a march with its Powershell. Can we do better in Perl? With composable streams of objects? Written in a modern OO framework (Moose)? You bet we can! This talk was given at the London Perl Workshop 2009, http://conferences.yapceurope.org/lpw2009/talk/2456

People like to claim Perl is line noise, with its sigils and regular expressions. But a lot of the features that make it possible to write, yes, truly awful, unreadable Perl, also let you write clean, maintainable code too. * those $%&* sigils! * there\'s More Than One Way To Do It * strings and data structures * map, grep, first class functions * metaprogramming and the CPAN * modern Object Oriented programming with Moose

Dubai, known for its towering skyscrapers, luxurious lifestyle, and relentless pursuit of innovation, often finds itself in the global spotlight. However, amidst the glitz and glamour, the emirate faces its own set of challenges, including the occasional threat of flooding. In recent years, Dubai has experienced sporadic but significant floods, disrupting normalcy and posing unique challenges to its infrastructure. Among the critical nodes in this bustling metropolis is the Dubai International Airport, a vital hub connecting the world. This article delves into the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system. About authorWith two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
