Continuing in my series on professional development – see the previous article on documentation here (ok so there has been a bit of a pause and I am stretching things to call this a series – I had intended to post this some time ago!). This post concentrates on the benefits of using an Issue / Task / Bug Tracking Tool…

Keeping track of development tasks and issues in a centralised system helps enormously. Living without task tracking for your issues is a lot like not having having source control for your code. A good task tracking system – such as Fogbugz or Countersoft Gemini helps keep track of what the team needs to do, allows issues to be delegated / reallocated to more appropriate team members and enables multiple lines of support (eg 1st line, 2nd line etc). It also allows transparency on tasks (allowing Jane who requested a new developer to check the issue tracker for progress rather than interupting the technical team) and (particularly for those of us that need to follow ISO9001 type standards) provides an Audit trail if used properly.

Of course its not just about standing up an issue tracking tool – you need to agree on things like

- what defines an High Severity issue over a medium severity one? What Service Level agreements do we have and how does the issue track tie to those (eg does selecting medium mean response within a day as opposed to high which requires a response within 1 hour for arguments sake).

- What is the process from issue inception through to resolution (does a new change request issue go to Bob -or better Bob’s role “Change Manager” – who allocates it to someone to estimate and changes the status to pending estimation).

- What level of documentation are you looking for in the comments associated with a case – is just referencing a source control commit enough (which is ok if your source control commits are verbose) or do you want a short explaination of what was done?

Clearly if done right this can allow your team to scale and stop your developers getting bogged down with admin (make sure there is someone overseeing the issue tracker). It can also make it easier to seperate support work from new big development work (the former you can give to junior colleagues to help them get up to speed with support from more senior ones – preventing senior guys/girls from getting bored with smaller stuff).

One other observation on this is that whilst you do need to be strict in order to implement these tools (eg ensuring that folks always use the tracker rather than continuing to email you all the time) you need to make sure they don’t become a barrier to communication between the technical team and its customers. One thing I like to do when involved in an operational issue is to cc the issue tracker in on an more detailed email explaining an issue – the customer gets a personalised response and the issue tracker captures the commentary (preventing time wasted by copying and pasting).

Would love to hear others thoughts on their use of issue tracking systems and the pros / cons.

We (those of us in the IT profession – or Information Management as one colleage recently suggested as an alternative*) don’t do ourselves many favours when it comes to using complex terminology and also expecting business people to understand and embrace IT best practises…

Whilst adopting concepts/practises such as Enterprise Architecture (EA), Data Governance, Information Management (IM), Knowledge Management (KM) are all well and good, the sheer number of buzz phrases and concepts must be bewildering for most  non techies. I will admit that sometimes I struggle with the difference for example with Master Data Management vs Master Reference Data without resorting to Google or Wikipedia.

Of course some will argue that is what the Architect or Analyst roles are all about – to match business requirements to IT solutions. But if we ever want colleagues or clients or stakeholders to truely embrace the concepts of Knowledge Management or Data Management / Governance we need to break down these barriers.

Its all too easy to get DM/IM/KM confused if its not the way you think. Generally / at a high level its accepted that Data can be converted into useful Information and that humans (eg employees) walk around with a lot of Knowledge that often needs to be managed (and shared) more effectively. But often we don’t take the time to even explain these concepts – we just jump into enterprise IT lingo and expect others to know what we are on about (or why it makes business sense). Sometimes colleagues can get confused by products such as Sharepoint and what they do – as they can think they are the solution to Knowledge Management – when actually they are just the product or underlying tool that can enable Knowledge Management – its embracing the core concepts of KM that is key.

If we are not careful we will go start to regress back to the bad old days of IT where the IT guy was locked in the cupboard as no one understood him…. Ok maybe thats going too far but you know what I mean!

Or maybe I am being unfair? After all every different business area I have worked in seems to have its own Acronyms (finance is a nightmare with IPOs, CFA, Swaps, Deratives etc etc etc) – is it now accepted practise to just Google terms you don’t understand and be proactive about learning these things? Unfortunately in my experience some people aren’t prepared to do that (unless its in their area of expertise) – and you just switch them off or loose them before you can sell them the juicy or beneficial part of the story.

* Information Management was selected as to not confuse people with “plain old Information Technology” – the physical desktop PCs, laptops etc and kit that every business needs. Information Management it was argued is different as it is the leveraging of IT capability (where IM people are part of the core business team) to improve the way Information is managed (or processes are operated) and used as an Asset rather than something just delegated to IT to “sort out”.

Here are some notes / interesting products/thoughts that were mentioned (apologies this is more of a set of notes for me than a proper blog post – if I get time I will refine this!)

Started the day on a conference call back to the office so had to miss the keynote which was a shame as it was by quite an eccentric guy who Microsoft have hired (as a UX Architect Evangelist) largely about keeping thing simple and usability from what I gathered of the end of the talk.

Day was very tough as a I had a late night catching up on various things to allow me to free up the Friday – its difficult sitting through talks when really tired!

Met with several former colleagues from my last company (and former colleagues from my current company) so was a bit of a blast from the past at times.

There appear to be a lot of development and interest around NoSQL / document based databases at the moment – definitely something to keep an eye on as it matures as a technology.

RDBMS in the social networks age
by Lorenzo Alberton

Database Graph Structures via advanced features of SQL, using SQL-99 and SQL-2003 functionality that certainly MySQL doesn’t have any many other DBs won’t have the 2003 extensions. Obviously using this kind of advanced functionality will have an impact on Database server load.

This talk felt a bit like it was flying in the wind of most new thinking at the moment (although to be fair – this is partly what Lorenzo has now put on his website below) which is to keep your database tier minimally loaded as it’s the part that has most issues with vertical and horzontal scalability (keep most of the CPU load in the web app tier as its easier to add more nodes there).

Legacy Code Talk by Ibuildings
doxygen – code documentation for any language not just PHP

ctags.sourceforge.net

BOUML bouml.free.fr (reverse engineering capabilities)

phpcs – Codesniffer (part of PhpUnderControl)

Thoughts for tackling older PHP4 based projects and code bases – get them in Source Control, start to apply Continous Integration type approaches.

Suggestions made around
Full isolation (separate server)
Using wrapper classes
Possible code rewriting routes for legacy code:
Going from random mix of PHP business logic and HTML outputting to neater procedural based code
Procedural to OO
OO to full OO

CouchDB
Early sight of the possible future of web application data persistance and replication. Interesting that CouchDB makes uses of HTTP as the connecting protocol. Might be possible (but probably not desirable apart from specific cases) in the future to create web applications that are JS direct to CouchDB in certain cases?

Web and mobile application monetisation models / Paypal X

Paypal appear to be launching a new platform / API

• Adaptive Payments
• Pay multiple recipients at once
• Partnership
• Chained payments (e.g. commission based payments)

Bit disappointed by this one as it was about PayPal’s API (https://www.x.com) rather than strategies for monetisation which is what the title lead me to believe.

Web Services Best Practise
At the beginning lots of stuff about basic HTTP (eg HTTP headers, Verbs) that ever developer should know about.

Lorna (also from iBuildings) who gave this talk seems to have a bit of a sarcastic talking down to you type tone I found slightly annoying – maybe she gives training to newbies all the time or something. Or maybe I was just tired. She had some interesting things to say about Web Services design particularly towards the end of her talk. The talk was caveated as being a bit of “a rant” and it was exactly that in places – felt like she was having a go at everyone a lot of the time!

Beers at the end sponsored by Facebook were a nice touch though, although I only had time to grab a quick one whilst chatting to Mark Schaschke from iBuildings and a couple of guys from my previous company. Think next year I will sit this one out to allow more developers to attend as think they will get more value out of it.

Some Recent Tech Discoveries I thought I’d share:

The Good:

Windows 7 RC – writing the blog post from it – excellent OS (and that says a lot coming from me!)

Ubuntu 9.04 -What can I say – wow – is the OS market hotting up or what? Right when they said the Browser will be the O/S – we’ll we aren’t there yet (well not until Google’s Chrome OS anyway…)

Spotify – sure lots of people know about this one now but great streaming music service. Kind of like a commercial radio station where you get to choose the playlist. But native version for Linux would be nice (netbooks will make this kind of porting happen organically now I suspect??)

Bitly – specifically the Bit.ly Sidebar for your browser – very clever. You’ll notice I’m starting to use more bit.ly links in my blog posts but for Twitter they are essential.

The Bad:

ebox – Not a good move to just try and install this on a Ubuntu box (tried this at home) screwed lots of stuff up. Nice idea but if you want to try it out use a seperate box. It looks good and the concept is a great idea but I think its a bit too flawed for me right now (sorry ebox devs).

Denyhosts (prevents brute force attacks on SSH by adding IP addresses that repeatedly fail to login to a black list – in /etc/hosts.deny)  silently stopped working some time ago on my Ubuntu server (due to an upgrade of Python by the looks of things). Following the fix on this forum thread sorted the problem although I found the file you need to change is:  /usr/share/denyhosts/daemon-control-dist rather than the one mentioned.

The Ugly:

HMG Info Sec standards (or rather the OTT implementation of) - I probably can’t say any more or I’ll get burned in acid (its a long and painful story…!)

More posts to come. Enjoy the summer everyone. I intend to on a ride around Litchfield tomorrow – embedded Google Map to follow no doubt…!

2009 has been pretty busy so far – as you can see from the lack of activity on here! Its almost 3 months in ‘09 and this is my first post!

For those of you interested in what I’ve been up to…

At work – we are in our busy end of FY period, I’ve been going to Brussels quite a bit for a project for the European Commission. Experienced a first – a meeting/workshop with (almost all) the EU Member state countries which was really interesting.

Lots of other exciting projects kicking off at the moment – looks like I will continue to be busy well into the next FY, which is good. Fingers crossed the economic downturn isn’t used as an excuse/ is a cause for cutting back on environmental and climate change projects.

On a personal level (also linked to work) Kat and I signed up to participate in trials for a new type of improved home thermostat (‘chrono-proportional’) for the EST (its a project that work are running).  It involves putting a few temperature sensors up indoors (and one outside) and we submit weekly gas/elec meter readings. These will monitor the effectiveness of our current thermostat – then later in the year we will have a new type of thermostat fitted and we’ll do the monitoring again.

The improved weather means I’m out on the bike alot more now which is good news, have also combined the riding with my new toy (which I got for Christmas) a Digital SLR camera – I’ll probably post up some photos soon.

Recent/Interesting Web Links:

Came across www.goodguide.com which is a product comparision site which lists how ethically produced,/green/healthy products are. Bit US specific at the moment but worth keeping an eye on.

An article on The Guardian’s (Free) Open Content API and DataStore. In fact the whole http://infosthetics.com website is worth a look at.

I’ve started playing around a bit with Twitter – have to say I was (and still am a bit) skeptical of this – so we’ll see how long I use it for. So far I have linked it with my Facebook status messages. Perhaps there’s a way of linking Wordpress to it so it can announce new posts?

Thats it for now – hopefully it won’t be as long until my next post!

Some sites that I found interesting recently…

I’ve been looking at quite a lot of Green IT/Business type issues recently www.climatechangecorp.com is a good site (even if it does heavily promote its events on the content).

Carbon Calculators article: http://www.climatechangecorp.com/content.asp?ContentID=5119 Its disappointing it mentions AEA only in the context of providing the emissions factors – we actually do a whole lot more including building online carbon/emissions data platforms (and calculators) ourselves.

Great article from Adobe on Web 2.0, SOA etc – gives a great overview: http://www.adobe.com/devnet/articles/web_end.html

Sun Microsystems came into to talk to us about their Java CAPS recently and it looks really interesting. We’ve already started to look at NetBeans IDE more closely (particularly the PHP plugin and its SOA/Business Process (BPEL) diagram/visualisation to BPEL XML code features…

See http://www.sun.com/software/javaenterprisesystem/javacaps/index.jsp

Dashboards, Flex with PHP etc:

One of my current projects is update our (data) visualisation and dashboard piece of our offering – as such we’ve been researching whats out there that we could use to enhance our technology stack:

Flex and PHP http://devzone.zend.com/article/3580-Building-Dashboards-With-PHP-and-Flex

Zend Framework/Adobe Media Remoting – http://corlan.org/2008/11/13/flex-and-php-remoting-with-zend-amf/

Interestingly Microsoft seem to be about to launch a new Dynamics AX product which is focused at Environmental data management – interesting to see the main IT vendors start to move into the space that we’ve been in for some time. This is really good news as it will give more deployment and integration options moving forward (eg for customers already using Dynamics).

Today we put live the new Intranet at AEA which has been Kat’s major project (should get to spend more time with her now its launched!) with some support from me and impressive efforts from the dev team.

Previously we had a static HTML Intranet which wasn’t really serving the needs of the business as well as it could. The new site is based on the AEA Framework – which I’ve blogged about a bit before. Essentially an extension of the Zend Framework glueing Silverstripe and other 3rd party components together with a single sign on approach (in this case we are also using LDAP to do logins from our current Novell infrastructure). We built on our HTML content crawler tool to hoover in the static HTML into the Content Management System.

Over time we will leverage the framework to create more efficient web 2.0 style business processes and work with PPC to combine it with other off the shelf tools that they specialise in; and hopefully push it globally across the group…

I’ve also had some exciting news this week which I will share when I can.

All exciting stuff!

Really impressed with the work my colleagues have done on the new AEA website (http://www.aeat.co.uk). This also includes the ecopath website which will be vastly expanded in due course.

I can’t claim to have been hugely involved (other than some bits and pieces behind the scenes) although this is partly because they kicked off the project whilst I was in Paris (talk about quick turn around!). The plan is to move it to the Silverstripe CMS in due course which will make management and updates easier.
