My OpenWorld!

Just a couple of weeks away, and my oh my, I am going to be busy at OpenWorld this year!

Of course, first cab off the block will be the OpenWorld swim! It it September and marvellously warm in San Fran, so what better year to come along and meet new friends, and get free coffee and donuts! Just grab a towel from the hotel and head down to the marina!

AUSOUG Connect 2019


Australian Oracle User Group (AUSOUG) is holding their annual conference series in Perth & Melbourne this year, again this year, and I'm lucky enough to be at both events.

If you can, hold these days aside for Connect 2019, meet an interesting mix of people, and talk with them about your experiences. Seeing & hearing what other people are up to can be invaluable.

  • Monday 14th October – Rendezvous Hotel In Melbourne
  • Wednesday 16th October (more...)

APEX Connect – A Slightly Different Conference

I wanted to do a write-up for the APEX Connect conference that happened in Bonn, Germany, a few days ago, as it was a slightly different conference than I normally go to and a slightly different experience for me.

I really don’t like DBMS_OUTPUT!

APEX Connect is a German event (put on by DOAG) that is focused on APEX, SQL & PL/SQL, and JavaScript. So more of a developers’ conference. It was an unusual conference (more...)

My Kscope19 Sessions

The #Kscope19 session list is out!

I've scored two sessions in the Oracle Application Express (APEX) track.

APEX for Forms Developers

My APEX experience has now surpassed a reasonable run developing Oracle Forms, I think I offer something to help the vast amount of Forms developers make the transition.

Managing Multiple Applications

A lot of my APEX work has involved developing applications in modules of a whole, in part because of steady transition from Forms (more...)

A dozen things to do with Oracle APEX

For this year's Australian Oracle User Group conference I decided to consolidate some of my favourite things to do with 3 of my favourite APEX features.

I considered this a bit of a 'lazy' decision, as it didn't really require any new research - but I think sometimes that can produce some good content, since I'm consolidating years of experience into a session.

It did give me a little leverage for one of my Kscope19 (more...)

POUG18

So that was POUG18 – the Polish Pint with Oracle User Group. This is the 3rd annual conference (and the 4th event) I have attended. IMG_4748A new location, many new speakers but the same vibe, energy and level of fun. Taking place in Sopot on the Baltic Sea, it was simply excellent and has to be the most fun Oracle conference in Europe. Its just a good size. Not too big, not too small.

We (more...)

Swiss pgday 2018

The cool thing about zooming out… is that your world appears to get bigger.
Being personally now no longer bound to Oracle, having the opportunity to work with PostgreSQL, also gives the opportunity to go new places and explore new possibilities. One of the cooler things is: participating in Postgres conferences.

Conference vibe

Where Oracle conferences, although having some deep technical aspects, tend to lean towards the business aspects of technology, especially today with Cloud (more...)

Speaking @ Rocky Mountain Oracle Users Group training days

I’m going to present outside EMEA for the first time – in RMOUG training days 2018 Denver, Colorado.
Can’t wait!

RMOUG Training Days

PGConf.EU, Postgres Rocks!!

On a rainy Tuesday morning we set off on a Polish Airlines flight to Warsaw.
Our target: PGConf.EU with some of the biggest crew EnterpriseDB ever sent off.
Our goal: spread the love of EDB within the PostgreSQL community, where EDB is such an intrinsic part of.

The evening before the conference promises to be an interesting one. We have rented off the Hard rock Cafe in Downtown Warsaw for the kickoff of our (more...)

Upcoming conferences – end of 2017

I’ve been accepted to the following upcoming conferences:

UKOUG Tech 2016 – Super Sunday

UKOUG 2016 is underway. This year I'm staying at the Jury's Inn hotel, one of a clutch of hotels within a stone's throw of the ICC. Proximity is the greatest luxury. My room is on the thirteenth floor, so I have a great view across Birmingham; a view, which in the words of Telly Savalas "almost takes your breath away".

Although the conference proper - with keynotes, exhibition hall and so on - opens today, (more...)

UKOUG Conference 2016 coming up fast

The weather has turned cold, the lights are twinkling in windows and Starbucks is selling pumpkin lattes. Yes, it's starting to look a lot like Christmas. But first there's the wonder-filled advent calendar that is the UKOUG Annual Conference in Birmingham, UK. So many doors to choose from!

The Conference is the premier event for Oracle users in the UK (and beyond). This year has another cracker of an agenda: check it out.

The session (more...)

Tech15

Last December I presented at Tech15, the largest Oracle conference in the Europe. Many thanks to the organizing team of this great conference. Here is my presentation about contemporary latches and mutexes in Oracle 12.1.0.2. It includes several post-conference additions concerning experiments with latch priorities and Windows time granularity.

    UKOUG Tech 14 in Liverpool

    I’ll be going to the UKOUG Tech 14 conference in Liverpool in December to give one of my favorite presentations: “APEX or ADF? From Requirements to Tool Choice”. I’m also leading the Development Tools roundtable, which is always lively at the UKOUG conference. If you want to discuss your options as a developer in the Oracle world, UKOUG Tech 14 is the place to be.

    G+ Public Hangout Fail

    tl;dr:Do not use public Google+ Hangouts under any circumstances, because people suck.

    Before the PyCon 2014 CFP came due, PyLadies hosted several G+ hangouts for talk proposal brainstorming. Potential speakers could talk over and flesh out their ideas with each other, producing better talk proposals. More importantly, it was a nice psychological stepping stone on the way to filling out that big, scary CFP form all alone. I thought they went great.

    I wanted (more...)

    Collaborate 14 and Vegas

    Collaborate 14 is coming soon and i can tell you that it is an excellent content learning and networking opportunity.  I have been going to collaborate for a while and have found it to be not only a place to learn but also to network with my peers .  We built the team to write the Practical Oracle Database Appliance  which is available here at Collaborate 13 and were able to deliver a book  with authors (more...)
