By
Norfolk Developers are extremely lucky to have Phil Trelford returning for both the evening event and a workshop the following day. Details are below. Please sign-up now.

What: Functional Hands on Workshop with Phil Trelford

When: Thursday, January 8, 2015 @ 9:00 AM to 5:00 PM

Where: The King's Centre, King Street, Norwich, NR1 1PH

How much: £20.00

Sign-up

Prerequisites: A laptop with F# installed.

Ham or Spam

In this session, we'll learn about the Naive Bayes classifier, and take a classic Machine Learning problem, recognizing Spam from Ham.

Hands On FParsec

FParsec is a parser combinator library for F# that let's you quickly build a recursive-descent text parser.

This session will introduce parsing domain-specific and general purpose languages using FParsec. Along the way we'll also cover creating a simple Abstract Syntax Tree (AST) with discriminated unions, and interpreting or compiling the language using pattern matching.



What: Write your own compiler in 24 hours with Phil Trelford

When: Wednesday, January 7, 2015 @ 6:30

Where: The King's Centre, King Street, Norwich, NR1 1PH

Sign-up

Write your own compiler in 24 hours
Phil Trelford (@ptrelford)

Compiler writers are often seen as the stuff of myth and legend.

In this session we'll step behind the proverbial curtain and reveal how compilers actually work.

Expect plenty of live code samples, primarily in F#, covering language design and parsing, all-the-way through to emitting code. This session is aimed as a primer for those interested in writing an external DSL, general purpose language or just understanding how these things work.

Catalina-Ant for Tomcat 7

By
I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th...

Write Your Own Load Balancer: A worked Example

By
I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

AWS Summit London 2025

By
It felt good to be back at the AWS Summit . I got a lot out of last year and this year was interesting too. I attended some sessions on interesting topics and some which reassured me I’m doing the right things.  It was good to catch up with some old friends, see my colleagues in person and chat with some of our suppliers at their stands. For an event which boasts 24,000 attendees, most things run extremely smoothly. My only real gripes are not being able to get into some sessions as they were full and the length of time it takes to get a cuppa! Keynote I skipped the keynote last year as I was keen to get on with some hands on labs. This year I thought I’d find out what it was all about. It took place in the 4000 capacity auditorium, but that was full, so I watched in one of the many smaller theatres.  The theatres aren’t exactly small, each one holds more people than the entire nor(DEV):con conference in Norwich. Each is separated by only a curtain and headphones are provided...
