JavaOne 2017 – Tuesday

It’s nice to be back in Moscone even it wears out more shoe leather.

The conference started on Sunday with a range of User Group meetings.  I unfortantely spent most of that day trying unsucessfully to revive my PiShark demo for my first talk.:  Java, Pi’s, and Flying Sharks: Or How to Create a Java Airship in <127 Grams   After a frantic rewrite I mostly saved the talk!

I’m torn now wether to finish of the project or abandon it. Talking it on the road is complicated due to its fragility and the perchance for conferences to balk at someone bring an ‘airship’  At Devoxx UK I ended up tethering the shark to the table. Which defeated the whole point of the project.

After a long day at JavaOne… Time to ESCAPE and have some fun.

IBM is hosting a party @ J1.  Where there will be men in dark suits trying to sell you a mainframe…  Only kidding.  Actually this should be fun.    All the details are here IBMJ1Party2017    Signup here

The new blue?

Well what an interesting couple of days.  My team open sources both the J9 JVM and Liberty core.

In one week we’ve made available the core parts of the IBM Java platform.  Stuff that’s been happily running customer applications for years (with all that implies in terms of quality, performance and  scalability ) is now available free and for gratis under EPL

You can get Open Liberty here   while binaries for OpenJDK with OpenJ9 can be found  at AdoptOpenJDK  while the main project is here

I  love the tag line @OpenJ9 : Give your Java application a thrill
Run it on OpenJDK with Eclipse OpenJ9

Now all it needs is a good OpenJ9 logo…

Found in the attic

Found a ‘meet the expert‘  interview page with me talkng about Java.  Strangly I have no recollection of ever doing this.  Pretty bland statements so maybe thats why I can remember the interview!

Devoxx UK 2017

Ah Devoxx.  This year it was bigger than ever.  Taking over the main hall for the exhibitors and using the old space for talks was inspired.  Loved it.

IBM hosted another Mad Scientist zone which, in my opinion,  was by far the best stand there.  We had  a dozen or so IBMers presenting their wares.  Some were full on commercial (but still totally awesome ) while others were completely wacky and existed simply ‘because’.

I brought my autonomous PiShark  (Thats an Air Swimmer run by a raspberry pi w) but had to have it tethered and strapped down for health and safety reasons. Apparently it was classed as an AirShip!

My colleague Laura Cowen blogged about her exhibit too

As well as being a Mad Scientist I also got to talk about Java.  Or in this case  Java Vulnerabilities.   The video for the talk is here  while the deck is here   This talk is a follow-on to my talks about Cybercrime.  Although I wont ever detail an actual vulnerability this talk has examples of the sort of code that ends up being exploited.

Progscon 2017

A refreshing 1 day conference in London at SkillsMatter

I talked about Cybercrime  (slides here )  Sometimes after doing this talk I feel a little guilty in not being able to give people a “just do this” solution. However, the situation right now is going to get a lot worse  and  the sooner we (as developers) understand our responsibilities the quicker “worse” turns into “better”

Jax Devops London 2017

I gave a talk at Jax DevOps in London yesterday.

The talk was entitled “Succeeding in the Cloud – the guidebook of Fail”  Slides are here    The talk originated in a conversation with Daniel Bryant  at a previous conference.  Daniel and I have done a few talks together around DevOps or Docker and it seemed the time to start to build the checklist of ‘things to do and not do’  So  this talk was the first go at building that list.  I don’t normally do checklist style talks as you can end up just reading the slides to your audience (boring)

I got reasonable feedback from attendees but I do wonder if its worth pursing. asis Ways to fail (and succeed)  in deploying to the cloud is a big topic and it might be worth taking one or two of the lists and focusing on them individually
