Running Part 2

Posted on by Rich Sharples

Just finished week 2 of my 10 week half-marathon training. Despite being away from home most of the week – I managed to exceed my mileage goal again – but didn’t make much progress on my pace. I have goal of finishing under 1hr 50m so need to be aiming for 8 minute miles; currently I’m barely hitting 10 min. miles consistently. With the warmer weather in the Triangle It was great to be running outside for the last couple of days (I find the treadmill desperately boring) and good to hit some small hills which should help bring my pace up.

Next week I’m hoping to squeeze in 16-18 miles and it looks like it will be warm enough to do most of those outside.

For what its worth, here’s my 10 week plan, it’s a variation of one I found here.

5 Reasons to submit a paper for JBoss World 2010

Posted on by Rich Sharples

Screen shot 2010-01-13 at 3.56.35 PM.png

There are only 9 days left to submit your talks for JBoss World 2010, in case you need them, here are some good reasons :

  1. It’s in Boston, In June. It’s a great city and the snow and ice will probably be mostly gone by June.
  2. You get a free conference pass, good for all Red Hat Summit / JBoss World sessions, keynotes, events, meals and parties
  3. You get one free night accommodation (in a hotel)
  4. It’s very likely IMHO that there won’t be a Java One this year – if you are looking for an opportunity to talk about what you’re doing with JBoss technology then this is *the* best place to do it.
  5. If you want to get into the weeds with highly technical content – then there’s a new track for that.

Call for Papers end in just 9 days !

Running

Posted on by Rich Sharples

I’ve never been much of a runner but always found running to be a pretty decent way to keep fit. It requires very little in the way of skill or technique; you don’t need any equipment; there’s nothing to set up and you can do it pretty much anywhere. If you’re busy with kids and travel and a job then you’ll find it pretty decent from a time investment point of view.

The only time I’ve really done any regular running was over a decade ago (notably before kids) – I ran the Bristol (UK) Half Marathon 3 times (98, 99 and 2000) as well as a few other shorter runs here and there (most recently the Los Gatos Dammit Run). But I’ve really never been much of a runner and find it pretty boring (more so on a treadmill) – I find cycling much more engaging and a much easier way to ‘turn off’; but cycling needs a lot more investment.

Over the Christmas break I signed up for the Tobacco Road Half Marathon and put together a 10 week training plan. I finished the first week this morning and am slightly ahead of my target. That’s fortunate because my plan (and the time available) has absolutely no contingency for injury or travel. And you guessed it – next week I’m traveling – the hotel has a small poorly equipped gym with exactly one running machine and the temperature in Boston isn’t going to be above freezing until August. If I was a runner – I’d be a fair-weather runner at that.

The Best and Worst of 2009

Posted on by Rich Sharples

s_full-moon

On the eve of the last day of the penultimate year of the first decade of the third millennium and continuing a tradition I started in 2005, here’s a quick summary of 2009 – ignoring everything between the peaks and troughs.

Best Moment

Aside from every 3 months when Red Hat announces another knockout quarter 😉

My eight-year old daughter is absolutely racing through the Harry Potter books. She’s finished the first three and is just over half way through the forth (Harry Potter and the Goblet of Fire). After she’s finished with each book we watch the movie version. I’ve always been a big Sci-fi and Fantasy fan and it’s good to have an excuse to watch the Harry Potter movies and fantastic to see my daughter see the magic of books despite the lure of on-demand cable, movies, video games, the internet, etc.

Biggest Disappointment

This is a tough one – it’s a toss up between the right wing nut cases who maintain that this country’s problems only started the day Obama took office; and the TSA who are still punishing millions of innocent travelers every day with their ill-conceived knee-jerk reactions because they have consistently failed to improve air travel security. I can easily ignore the right wing nut cases – but I have to travel and comply with the TSA’s pointless and ineffective rules. So the TSA wins.

Best Application

My utilitarian ThinkPad semi-failed me over the summer so I used that as an excuse to flip back to using a Mac. I still use the ThinkPad as a desktop in my home office running Fedora but it is no longer portable. I’ve been using multiple machines for years (typically running OS/X and one or more flavours of Linux) and never found a nice simple way to share files until I found Dropbox. I use it all the time and now find it invaluable. [note to self – I should probably post some tips and ideas of how I use it at some point]. So Dropbox gets the top-spot. Runners up are MindNode (mind mapping) and Evernote (lists, notes, etc.). Note to personal productivity software developers – it’s no accident that all these apps. integrate with my iPhone.

I should also add; or repeat, as I’ve said it before – AR is going to be *big* – maybe this year enough people will be carrying a powerful smartphone to make 2010 the year of AR.

Best Book

I had high hopes for “And Another Thing”, Eoin Colfer – Book 6 of the HHGTTG “trilogy” but I think it was a mistake to try and replicate Douglas Adam’s style – that’s too high a bar for any author in my opinion. I’m currently wading through “Too Big to Fail”, Andrew Sorkin – an epic and well researched saga of the financial grey goo but I can’t count that as I won’t be finished with it this year. So I’d have to choose the “Omnivore’s Dilemma : A Natural History of Four Meals by Michael Pollan. The book didn’t change my life in a major way but it has made me a bit more selective about what I am wiling to put in my stomach.

Anyway, enjoy the Blue Moon tonight and have a healthy, prosperous and happy New Year.

The Evolution of Enterprise Java

Posted on by Rich Sharples

400px-Human_evolution_scheme.png

Zallinger’s “March of Progress” from wikipedia.

I’ve been part of the Java ecosystem for long enough to see and be part of every Java EE / J2EE release to date. I still have a Forte SynerJ box-set somewhere – we claimed it as the first fully integrated J2EE 1.2 App Server and IDE – that was around 1999 and I was part of Sun for every subsequent release up to Java EE 5.

With the final votes in for Java EE 6 and with the year and decade coming to an end – it seems a fitting time to look back and see how far the Java EE platform has evolved :

  • J2EE 1.2 (1999) – announced just short of 10 years ago was the first attempt to create an umberalla specification to cover some existing web-tier, messaging and data access technologies (JDBC, Servlets, JTA, etc.) as well as the new middle tier technology – EJBs.
  • J2EE 1.3 (2001) – was from my recollection the first broadly adopted and deployed version, it added Connectors (a standard way to connect to back-end ‘legacy’ systems), some rudimentary support for XML Web Services and a pluggable security layer. EJBs got a major overhaul.
  • J2EE 1.4 (2003) – added JMX, a gaggle of specs. to support Web Services (JAXR, JAX-RPC). I think around this time – everyone had written their first App. using EJB’s and had learned that combined with CMP (Container Managed Persistence) they weren’t exactly getting the productivity boost they were hoping for. I think J2EE 1.4 was the “Vista” of Enterprise Java – over-engineered and ultimately underwhelming.
  • Java EE 5 (2006) – A name change and some new hope – mandatory XML deployment descriptors gave way to annotations, persistence took a lesson from the de-facto ORM solution – Hibernate. There was an alternative to, ahem, RPC-style Web Services with the inclusion of JAX-WS.
  • Java EE 6 (2009) – It’s been a while in the making and had a bad start but after ten years I think we now really see the start of a cohesive platform with a common programming model via CDI (JSR-299) and many of the criticisms leveled at the platform have been answered.

Java EE 6 also defines the new Web Profile – this is essentially a slimmed-down EE focussed on web applications. I think it’s much more than that – I think it’s an opportunity to really redefine the Enterprise Java platform and shed some of the legacy APIs. While the backward compatibility that EE dictates has been good – it’s also contributed to some bloat in the platform.

It’s interesting to see how the size of the Java EE spec. has changed over the years (assuming size of the spec. is a reasonable indicator of complexity)

  • J2EE 1.2 weighed in at just 140 pages;
  • J2EE 1.3 added about another 25% (174 pages);
  • J2EE 1.4 increased it by almost 40% (246 pages)
  • Java EE 5 actually bought the page count down by 10%;
  • and the last draft of the Java EE 6 spec. I read only added about 6% (236 pages) – despite some pretty major enhancements.

Despite several rounds of consolidation and various acquisitions – vendor support has remained impressive. There were 18 J2EE 1.2 certified servers, and even seven years later there were still 13 (for Java EE 5). I’d be surprised if there weren’t at least 10 vendors supporting Java EE 6 at some point – even after Oracle has assimilated BEA and Sun.

Despite its huge adoption, Java EE and the process by which it is defined (the JCP) has drawn a lot of criticism. Releases have often fallen short of expectations, been perceived as overly complex or taken too long to deliver; but despite the criticisms nobody can deny that Java EE has been a huge success. Java EE is not just a specification – its grown into an entire category of the software industry. I can think of no other technology that has bought so many competing vendors together to define such a broad and widely use platform.

I’m sure the JCP isn’t perfect and I’m sure vendor politics gets in the way of progress from time to time and Sun’s stewardship of Java hasn’t been flawless but step back and try to imagine what our industry would be like without an open and collaborative Java ecosystem. It will be interesting to see whether Oracle take a different approach (as they’ve suggested in the past) when they become the new stewards of Java. Let’s hope hey continue to encourage collaboration and diversity.

The various expert groups that define the Java platform is not, as many suggest, completely controlled by big vendors. My own company Red Hat is not an industry behemoth, there are divisions and offices within companies like IBM and Oracle that are bigger than Red Hat and JBoss, the middleware business unit of Red Hat is only a part of the entire company. Despite that – Red Hat has demonstrated yet again it’s willingness to punch way above it’s weight and has had an influence on Java EE disproportionate to it’s size. Congratulations to Gavin King, Pete Muir, Sacha Labourey. Emmanuel Bernard, etc for tirelessly pushing for simplicity in the EE platform.

JBoss AS 6 Milestone 1 is out and includes some of the key Java EE 6 features. Releases seem to be coming pretty frequently so you’ll see more EE 6 feature appearing over time.

JBoss : Vision and Execution

Posted on by Rich Sharples

Another nice score card from Gartner puts JBoss Enterprise App. Platform in the leader’s quadrant of the Gartner Magic Quadrant for Enterprise Application Servers. That’s the fourth year in a row, in case you were wondering. Unscientific as it is – comparing with last year I’d say the leaders are widening the gap (cumulative advantage ?) and JBoss specifically has inched up on the Ability to Execute axis.

Interestingly, Salesforce.com were joined by a couple of other PaaS vendors in the MQ this year – it will be interesting to see if there really is a new wave of infrastructure bearing down on the established platforms. The contemporary PaaS offerings I see today under-achieve as general purpose developer platforms and that leaves them competing with IAAS based on more traditional / established technology (Java, .NET) on cost and convenience terms. It will be good to see “Cloud” get beyond the current over-hyped phase so we can see how this will play out.

Releases / Lifecycles and other Product Management Miscellany

Posted on by Rich Sharples

This week we GA’d JBoss EAP 5.0. As you’d expect from a new release there’s a long list of new features, capabilities and APIs and at some point I’ll talk about those some more. But the intention of this post is to give you an idea of some of the other less visible things that have happened with this release. EAP 5.0 marks a key milestone in the evolution of JBoss and demonstrates where we’re heading with the JBoss Platforms.

Performance

We set some pretty aggressive performance targets for this release. By comparison to JBoss EAP 4.3 we see an increase in peak throughput of about 20%, faster response times and more scalable HTTP connection handling. Performance is an ongoing activity and we’re continuing our investment in improving it in future releases. Performance at any cost is interesting to few outside of Formula 1 and Rocket Science and it isn’t a goal – we’re specifically interested in price / performance using a broad range of typical, real-life workloads.

Quality

Popular Open Source technologies (like JBoss AS – on which EAP is based) have always had the benefit of a large community who actively poke and prod. and push the software in different ways; who peer into the design and code and offer improvements.The result is some pretty decent, efficient and well polished code. But with the JBoss platforms we go one (or several steps) further. For EAP we had a long and active Early Access Program. It started back in April and is only now winding down as FCS customers complete their work. The diagram Below illustrates how we connect the AS and EAP lifecycle, the upstream (AS) GA essentially starts our EAP Early access program. This allows enterprise customers to start using a stable (though incomplete) release with the full backing of Red Hat Global Support.

Screen shot 2009-11-06 at 9.50.09 AM.png

Obviously the diagram is a massive oversimplification – EAP is more than AS – it is the integration point for Seam, RESTEasy, the installer, mod_cluster and the Apache Native components.

With every release we also enhance our QE coverage; in the case of this release there was a bigger focus on Performance, Stress and Longevity testing using larger and more complex topologies and a broader range of workloads.

Lifecycle

We’ve also refreshed and restated our product update and support policy for all JBoss platforms – the hope is that it’s more clear, better aligned with other products from Red Hat and puts even more distance between us and our Open Source competitors.

Screen shot 2009-11-06 at 9.54.11 AM.png

Ease of Use

A while back we kicked of an Internal initiative called “Andiamo” – I talked a little about it at JBoss World, and Mark wrote about it recently. While much of what we have planned around Operational and Development Ease of Use is planned for release beyond EAP 5.0, EAP 5.0 does lay the foundation for some of the things we need to achieve. The new Microcontainer provides us a very flexible and powerful toolbox that will allow us to build the middleware platform for the next decade. Specifically around ease of use, and as a taste of things to come we did provide a first cut of the new embedded console (it replaces the old JMX and Web Consoles). It has pretty limited functionality right now but I think it achieves the goal of making simple tasks simple to do.

What’s Next ?

The EAP Springtime Release (nominally EAP 5.1) is well underway and we’ll be pushing for even greater performance gains as well as defining the target platform for an upcoming Common Citeria (EAL 4+) certification.

We’re also underway with the EAP Lancer Release (nominally EAP 6.0) which will be the first major output of the Andiamo work as well as supporting the new Java EE 6 platform.

Onwards and Upwards.

Tab Sweep : JBoss World 2009

Posted on by Rich Sharples

JBoss World 2009

JBoss World 2009 is just under 3 weeks away and it’s still not too late to register. GEICO CIO Jess Reed will be one of the keynotes this year underlining that JBoss World is a great place to come and learn how other organizations just like you have saved money and improved performance and stability by moving to JBoss and Red Hat.

“GEICO is the 3rd largest passenger auto-insurer in the US and provides coverage for 9 million policyholders.”

“Reed will highlight GEICO’s deployment of Red Hat’s JBoss Enterprise Middleware and their use of open source middleware software for mission critical platforms”

You can even save money ($400) on saving money by registering before the event.

I’ll be at Red Hat Summit / JBoss World all week and have a couple of sessions talking about JBoss Enterprise App. Platform both present and future. If you’re around and want to chat – get in touch.
