Top 7 Agile Tips I learnt as a Product Manager 
Benjamin Mitchell (@benjaminm)

Many people have experienced using Agile approaches within teams to deliver more working software, but what can be learnt from combing these approaches with Product Development? This talk will cover the top seven hard-earned tips I learnt from several years spent as a Senior Product Manger for BBC Worldwide. Ever wondered how you could influence the product you were building? How can you use Agile approaches to learn about what the right product to build is? How do you overcome defensiveness? How can you design experiments that challenge assumptions and encourage change? This talk will provide some answers, combining ideas from organisational learning, psychology and negotiation.

Britain’s Biggest Technology Company Sells Out To Japanese Tech Firm


If there was any concern that Brexit would have a negative impact on foreign investment in the UK, the doubts were somewhat quashed this week when ARM Holdings announced a takeover by Japanese tech giant, Softbank, in a deal worth a staggering £24bn.

ARM Holdings is Britain’s biggest and most successful tech firm. Founded by entrepreneur, Hermann Hauser in 1990, the company made its mark with the vintage Acorn Archimedes and BBC micro:bit.

Today, the ARM microchip powers practically every digital device imaginable, including computers, iPhones and Samsung’s range of mobile products. Last year, the company sold 15 million microchips – more than its US rival Intel has sold in its 48-year history.

The ARM microchip is seen as the next-generation for microprocessor architecture, and whilst Britons have a right to be proud, we can’t help but feel it’s a shame the company is being sold to overseas investors.

We’re also curious how the likes of Apple and Google feel knowing their industry “allies” have handed over the new-generation microchip to a Japanese firm.

The sell-out also raises questions about the impact such a massive acquisition will have on the British economy. New PM, Theresa May has already voiced her determination to put an end to foreign takeovers that do not favour national interest.

However, on this occasion the UK government has been quick to respond with a positive message. “This is good news for British workers, it’s good news for the British economy,” a spokesman said. Given Softbank has already stated its intention to double the 3000-strong workforce of ARM Holding, we can’t argue with this.

Furthermore, in Softbank, the British tech giant is being adopted by a faithful parent. In recent years, the Japanese firm has already acquired Vodafone and Sprint together with a French robotics company, Aldebaran. Founder of Softbank, Masayoshi Son has said that ARM Holdings is one of the pillars of the company’s growth strategy.

The ARM microchip is used in numerous household items such as smartphones and tablets, computers, TV’s, Smart home technology, Smart cars and wearable tech. The microchip also powers smart cities and drones. It seems the Japanese tech giant has acquired ARM with a view to progressing the next-generation of “The Internet of Things” (IoT).

IoT is the proposed idea that by interconnecting digital devices our lives become much easier and more convenient. Possible scenarios include fridges that add food to the shopping list on your mobile phone when you are almost out, and kettles that tell you it’s time for cuppa.

We are experiencing a rapid development in mobile technology and in the very near future we will practically be able to manage our lives from our smartphones. To many people this may be a scary proposition, but it is almost guaranteed that most will embrace the convenience IoT technology offers. And a certain Japanese-owned British company will be central to making our future lives possible.

Immune to the EU referendum?


I actively avoid posting about politics on social media. To me it’s a personal thing. I’ve also been avoiding posting about the European Referendum. I have a view, in fact I’ve already voted, but it’s personal.

There are a lot of businesses who are encouraging their employees to vote one way or the other, notably BMW and JCB. I’ve considered the referendum form a Naked Element point of view and, as things stand, I cannot see clearly how either outcome would affect us. Our current clients are continuing to invest in the software we’re writing for them and don’t appear to be putting off any decisions until after the referendum. New enquiries are still flowing in at the same rate.

We have a client for whom we recently finished a web application. They asked us to bill them for the hosting every month. Following the first invoice they asked if they could be billed for the next twelve months instead. We use Digital Ocean for hosting and they charge in dollars. Normally this wouldn't be a problem, we'd calculate the cost of the hosting for the most recent month, multiply it by twelve and just absorb any, likely minor, fluctuations in the exchange rate.

One of the most frequently reported likely consequences of leaving the European Union is a significant drop in the value of sterling compared to other currencies, such as the dollar. This could significantly increase the cost of Digital Ocean hosting to Naked Element. Is it enough to worry me about the possibility of exit or to ask Naked Element employees and associates to vote in? No, of course not. If we do leave and the exchange rate does drop, it’s just something our business, like many others, will have to deal with. The worst case scenario is that we have to find ourselves a UK provider or one who charges a reasonable rate in GBP.

So far this is the only potential effect of the referendum I am aware of for Naked Element. I am sure time will tell, but Naked Element appears otherwise immune. Once we explained the situation, our client was happy to wait until after the referendum for their twelve month hosting invoice.

In the meantime I'm looking forward with interest to this week’s result and to see how the country votes and the immediate and long term effects of the decision.

Hot Gossip: Microsoft Buy Linkedin for $26.2 bn


There’s been another tech buyout. Microsoft has announced the purchase of Linkedin for a cool $26.2 bn. Even for the titans of software, that’s more than pocket change.

Indeed, it’s the tech company’s largest acquisition ever, so it’s safe to say that plans for future growth are floating on a cloud of optimism. But will this partnership have the whereabouts to satisfy professionals of the business world?

Let’s face it, neither Linkedin nor Microsoft have the best track record for performance or a reputation that fills end-users with confidence.

Microsoft products are often described as “useless” and their customer service is a shambles. Linkedin is not without its user critics either and attacks by cybercriminals have dented the credentials of social media platforms.

However, let’s give innovation a chance here and float on that same silver-lined cloud the companies CEO’s are sky-surfing on. Maybe between them, Microsoft and Linkedin can cover themselves in glory.

Increase Productivity

In an email to staff, Microsoft CEO noted how similar the culture of Linkedin is with the software company. Both firms have ambitions to reinvent productivity and business processes and “seek to empower every person and organisation on the planet.”

The intention behind this common pursuit is to help “people find jobs, build skills, sell, market and get work done.” So they are covering all the bases. And the tools are there, or almost there, to make it work.

Usability is an issue for Linkedin users. It can sometimes feel like a service you are obligated to do rather than a tool you want to use. It’s not all that effective for networking either.

In the last few years, Linkedin has moved to address user issues. The capacity to share content, leave comments, add images and publish posts has bought the platform in line with other leading networks such as Facebook. It’s helps with brand visibility at least.

Last year, the professional network purchased Lynda.com with a view to providing effective tools that aid training and learning. That’s all very well and good for job seekers, but what about professionals hoping to win contracts or partner with other firms?

Linkedin Profinder

Launched earlier this year, Profinder is an old idea wrapped in new packaging. The service gives companies a platform to promote their projects and find freelancers with skills to pull it off.

The service essentially mimics freelance for hire sites like People per Hour and Fiverr. For the time being, Profinder is free to use for both companies and freelancers, and creates another potential revenue stream for skilled professionals.

The benefit for businesses is you can find trustworthy and reliable professionals to complete your projects. There is an argument that professionals on Linkedin have more credibility.

However, the problem for freelancers is, winning work becomes a bidding war against other service providers. Rarely will you earn what you are worth and may have to pay transaction fees on top.

It will be a tidy income screen for the merger. Microsoft will help program the interface to make it user-friendly.

But where else does Microsoft fit into the bigger picture? Other than rescuing Linkedin from financial disaster after shelling out £1.5 bn for Lynda, it’s not easy to see how the software company can improve the business model. A few tweaks to the interface does not justify the £26.2 bn spend.

It will be interesting to see how this adventure pans out. After all Microsoft hardly have the best track record when it comes to collaboration. Last month, the tech company broke ties with Nokia and wrote off a $7.2 bn investment that lasted just two years.

And the companies previous venture into social media was disastrous. Have you heard of the chat service Yammer? No, not many other people have either because nobody uses it. Probably because Microsoft tried to tie Office 365 with it! Something Linkedin professionals might have to cope with.

The partnership between Microsoft and Linkedin could prove to be pretty exciting, but given Microsoft’s track record, the network is likely to get worse before it gets better. Watch this space!

NorDev Event: Fast-paced multiplayer & Stories of British-based Robotics Start-ups

What: Fast-paced multiplayer & Stories of British-based Robotics Start-ups

When: Wednesday, July 6, 2016 @ 6:30pm

Fast-paced multiplayer: an introduction to client-side prediction and server reconciliation. 
Gabriel Gambetta (@gabrielgambetta)

Creating multiplayer games is hard. One of the reasons is that networks are unreliable and laggy. In this talk we'll discuss several techniques to give players a smooth experience even under suboptimal conditions.

Gabriel Gambetta 

Gabriel was a senior software engineer at Improbable for a year because turning into its Head of Marketing for some reason. Before Improbable he had spent four years as a software engineer at Google, and nine years running Mystery Studio, a small indie dev studio, where he started researching networking techniques for multiplayer games after making yet another match-three stopped being challenging.




Transforming the Status Quo: Stories of British-based Robotics Start-ups 
Dominic Keen (@dominickeen)

Autonomous robots open up amazing possibilities for highly productive one-to-many modes of human-machine operation.  Rather than needing to push your vacuum cleaner around the house, you’ll soon just get it started and tell it whether it has done a good job at the once it has cleaned up all the dust. These new types of autonomous machines will allow us to reclaim much lost time and will usher in new paradigm of hyper-performance that entirely transforms the status quo for both the users and creators of technology. Through telling the stories of the foremost British-based robotics start-ups, Dominic will demonstrate the breadth of robotic invention and the hope it gives us all for the future.

Dominic Keen 

Dominic Keen started Britbots to helping British robotics start-ups flourish by providing access to capital and opening up new commercial opportunities.  He brings a wealth of experience to rapidly growing early-stage businesses, having previously floated the software business he created on the London Stock Exchange. Dominic has been a member of the Great Britain judo team and graduated in Engineering from Cambridge University. He is a passionate advocate of the societal and economic benefits of widespread robotisation.

"I am a successful British entrepreneur. Having previously floated the software business that I founded on the London Stock Exchange, I now help exciting ventures to maximise their growth potential. My fascination with all things robotic drives an impassioned evangelism of the field."

A little piece of code

I’d like to introduce you to a little piece of code. If, as an experienced developer, you’ve had an interview with me, the chances are you’ve been asked to evaluate this piece of code in one form or another:
public static void main(String[] args)
{
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
final Connection con =
DriverManager.getConnection(conectionString);
final Statement stmt = con.createStatement();
final ResultSet rs = stmt.executeQuery("...");
while(rs.next())
{
System.out.println(rs.getString("id") + ": " +
rs.getString("message"));
}
rs.close();
stmt.close();
con.close();
}
catch(Exception e)
{
}

Assuming nothing goes wrong, this piece of code is just fine. However, if there is an exception there is a resource leak.

In 2000 I worked on my first commercial  project, a Windows desktop application. There was a certain amount of graphical manipulation and every so often the application would grind to a halt and and then eventually crash. A few people I spoke to suggested that there might be a resource leak. I was fresh out of university and I couldn’t believe that C++ for Win32 wouldn’t clean-up after itself. How wrong was I? It was a resource leak. After I got a handle to and used a Win32 resource, I wasn’t releasing it. As soon as I wrote a guard class to manage and automatically release the resource the problem went away.

I’ve been fanatical about memory and resource leaks ever since.

In 2013 I worked on a Java project with a large number of integration tests which executed a few scripts against the test database once each for many tests. All the tests ran just fine individually in my IDE, but sometimes when running all the tests at the command line, it would just hang. I don’t remember how I worked it out, but I realised I was running out of database connections as upping the maximum number available to the tests fixed the problem. Every time I encountered the problem I upped the number of connections in the pool. This of course can only go so far and I was very uncomfortable about it as I didn’t understand why the connections weren’t being released after the tests.

I’m using the same piece of boilerplate Java test code in a current project and a couple of times the problem came back. Then I reached the limit of the number of connections I could create in the pool, so I had to find the leak. This time it didn’t take too long and the problem was here:
try
{
   ScriptUtils.executeSqlScript(dataSource.getConnection(), resource);
}
catch (SQLException e)
{
   // ...
}

Calling getConnection on the data source returns an unmanaged connection object.  As you would expect, executeSqlScript doesn’t and doesn’t expect to have to manage the connection, so every time it executed a sql script it got a connection from the pool and never put it back. No wonder, when this piece of code is being run a few hundred times it was running out of connections and just hanging.

As I said, I've been fanatical about resource management since my early professional career, but even I get caught out sometimes. This was one of those times and it reminds me not to give other developers such a hard time for obvious mistakes.

Security: It's A Cloud Thing 
Steve Love

Cloud Computing brings a multitude of benefits to businesses of all kinds, whether in the tech sector or otherwise. It is not without risk, however. Some of the risk is new, and some of it all too familiar. In this talk, Steve Love looks at why cyber security still matters in The Cloud.

Steve Love

Steve Love is an eclectic programmer who is fascinated by the applications of technology and its consequences. He is the founder of PerfectCobalt Cyber Security and can be contacted at steve.love@perfectcobalt.com


My last ever null check  
Anthony Ragu

Modern software development projects are littered with cross-cutting concerns (think logging or verification). Aspect oriented programming enables increased modularity through the implementation of interceptors and code weaving.

Not only does this simplify your code base but also ensures that, as a developer, you can focus on the actual task at hand.

Here, we will explore how to use AOP and Unity IOC Interceptors in a .NET Project to check for nulls between method calls.

Engaging children in technology – the micro:bit satellite inventors kit

The original BBC Micro enabled and inspired many of us to start programming and pursue a technical further education and career. With the BBC microbit, the BBC are trying to inspire the current generation of young people to get creative with technology. The microbit is a ‘thing’ in the Internet of Things era. This breakfast meeting will introduce you to the microbit, enable you to get hands on programming (if you want to bring your laptop), and present the ambitious plans behind the Satellite Inventors Kit for microbit which brings science and technology together with an exciting Space context.

Although schools can obtain microbits for free, and there has been tremendous effort producing lesson plans for teachers, the fundamental state of our education system requires the support of the skilled technical community. We need to step up and support our teachers, schools and pupils by helping to deliver technical materials. It would be a fantastic outcome of this meeting if we could start a movement in Norfolk to do this, your input on how is most welcome!

Paul Foster

Since joining Microsoft in 1994, Paul Foster has worked across a wide range of sectors and with a wide range of customers, providing a mix of technical and strategic guidance around the creative use of technology in relation to their business needs.

As an established public speaker across Europe and having spent a considerable amount of time working on the cutting edge of technology providing leadership and inspiration on topics like Smart Devices, Cloud Computing, Education and App Development, Paul is currently working as a Principal Technical Evangelist for Microsoft UK’s Developer Experience Group, focusing on the building of next generation sensor webs which automate the gathering of data from disparate sources, and how to enable the creative analysis of this data to start a new era of perception.

For a short time Paul was a member of a high-wire flying trapeze circus troupe, and is a keen roboticist.
