JavaScripting across the universe

Image
By
I’ve been using JavaScript reluctantly on and off for years. I’m currently working on a project that is highly dependant on JQuery based, handwritten JavaScript. Just as Rupert described in this workshop, I am one of the world’s copy-and-paste JavaScripters, so I thought it was about time I looked at it more closely to see what I was missing. I recently took on an apprentice who also needed to learn JavaScript, so a Norfolk Developers workshop was ideal for us.

We all know there’s a software development skills shortage nationally and very much so locally and this is something Norfolk Developers is trying to do something about by introducing a series of introductory workshops aimed at those with little or no experience. Initially Norfolk Developers will be concentrating on web development skills such as HTML & CSS, JavaScript and JQuery. There are also plans for introductory workshops for iOS and Android mobile development. The group will also continue to cater for the more experienced developers with their regular series of intermediate and advanced workshops.

We all know JavaScript is evil, right? Yes, but it’s a necessary evil and there are reasons it’s evil. This was very well explained by Rupert Redington at Norfolk Developers’ JavaScript Starter Kit, beginners full day workshop. It was created in two weeks and suffered a little because of that, but we are where we are.


What was really great about the workshop for me was that I was able to learn and understand the details of the language I had missed before, such as the different ways things are compared for equality in the language.

After an interesting and in depth introduction to the language Rupert introduced us to NodeSchool, which is a series of tasks designed to help you learn and write JavaScript one step at a time in a rewarding way. You write the code to solve a problem, run the test and it tells you whether you have it right or not. I could have done that for hours!

In the afternoon we brought together a lot of what we had learnt in the morning to write a simple one page web application which used our browser’s API (Application Programming Interface) to find our current location and an external API to look up where the nearest public toilets were to us. It was fantastic to see what we’d learnt solving a real world problem.

Rupert will be back in the summer running an updated beginners JavaScript workshop.

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...

Remember to Delegate: The Triangle of Trust

By
So you think you can lead a team? I’ve been talking and writing a lot about leading a software engineering team in 2025. I started thinking about it more deeply the year before when I decided to give a colleague, who was moving into team leading, some advice: 'Doing the work' isn't the only way to add value Remember to delegate Pick your battles Talk to your team every day Out of this came a talk, “So you think you can lead a team?” which I gave at work, at meetups and at conferences in various different formats during the first quarter of 2025. Here I am looking at Remember to Delegate and an idea which came out of discussion around the talk, The Triangle of Trust, in more detail. Delegate Delegation is a crucial skill for any team lead, yet it is often one of the most challenging aspects of leadership to master. Many leaders, particularly those who have risen through the ranks as individual contributors, struggle to let go of tasks, fearing a loss of control or a dip in ...

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...
