Find Us at Oracle Code

Oracle Code (@oracledevs) begins tomorrow in San Francisco, and we’ll be there.

What is Oracle Code? Check out the video, which includes our Gadget Lab at HQ, robot arm demo, VR egg chair and Tony O giving a tour.

Specifically, Raymond (@yuhuaxie) and Mark (@mvilrokx) will be hosting IoT Workshops like they did during JavaOne and OpenWorld 2016. Also, Raymond’s Pac-Man on a String will be one of the (more...)

Art of Making

Art of Making

I caught up the making virus from our engineers, and, jointly with a fellow parent, volunteered to teach an “Art of Making” seminar at my daughter’s school (my friend’s son came up with the title). Our hope was to bring STEM, art, and design thinking together. (I am supposed to represent art and design thinking, but secretly dream of learning some STEM along the way).

There are about thirty different seminars that (more...)

RIP Oracle Connect

Blogging and long-form content seem so tedious to me nowadays, but if you’ve read here for a while, you’ll recall that I used to post several times a week.

One of the reasons I’ve kept this blog running in the era of ever-shorter content is that it keeps a historical record of this team’s work and our thoughts. As an emerging technologies team, we know that not all our thinking will make it to daylight, so we (more...)

Oracle DBSAT first experience

“Back It Up!!!”


“Expectations is the place you must always go to before you get to where you're going.” 
― Norton Juster, The Phantom Tollbooth   

In a recent post in the Oracle General database forum the following question was asked:


Hi,

I have 3 schema's of almost equal sizes, off which only two are creating the backup's (Hot backup). One of the schema's is not creating any backup, by not creating I mean, the backup file that  (more...)

What new?

Interesting news about the coming Oracle 12 Release.

Some Video of Our Exploits

Lots going on here at the ‘Lab as always, and now, I have video to prove it.

First, a large of our daily routines now involve showing off our demos to visitor to the User Experience Cloud Labs at Oracle HQ. Our demos live in a space we affectionately call the Gadget Lab, and during last year’s OpenWorld, Gozel (@gozelaamoth) had a film crew take some video.

Now you can get a sense (more...)

An Oracle Partner Cloud Integration Hackathon in Sydney

At the end of November, Laurie’s (@lsptahoe) Apps UX Innovation Events team organized another fabulous hackathon, this time in collaboration with the Oracle Sydney Office.  The goal of the hackathon was to integrate several Oracle Cloud Services and hack together an application built on top of those Cloud Services, using a toy or other device. The AppsLab was prominently represented by Jake, Noel, Raymond and myself as we were invited mentors for the various teams (more...)

Holiday Project, A DIY CNC Adventure

This past holiday break, I have mostly stayed in the garage – setting up a CNC machine and cutting all the things that I deemed cuttable by it.

Raymond is busy on CNC jobs

Owning a CNC machine has been on my list for a long time, it is just out of my price range for a high quality professional grade machine, or maybe not useful enough for a “toy” level DIY one. But every time I built (more...)

#Oracle cutting in inspiration and new business?

Over the many years Oracle has been leading the database world, I guess they are now taking something of a wrong turn.
Let me briefly fill you in on my thoughts.

Basically I see two “minor” shifts that are significantly indicative of this:

  1. Oracle Standard Edition 2
  2. Oracle ACE Program

Okay, so you might think I am crazy, but let me try to explain.

Oracle Standard Edition 2

Sometime last year, the long expected, (more...)

Google Home Notifier

Working in an emerging technologies team has a lot of perks. One of them is to kick the tires of technologies that are about to become mainstream. It also has the somewhat fun privilege to gain interwebz bragging rights or the equivalent of the emblematic/annoying “first” comment that plagued the web forums just a few years ago.

Among my list of “first”* (afaik) are the following:

Emotion Recognition at Oracle Maker Faire

Emotibot, an emotion sensing robot.


A few weeks before the first ever Oracle sponsored Maker Faire, I was experimenting with some of the cognitive (vision) recognition APIs available. Google Vision API, Watson Visual Recognition and Microsoft Computer Vision API are some of the biggest players in this field right now.

After testing all of them I found the idea of Microsoft’s CaptionBot really compelling: Upload an image to the CaptionBot and it will try to come (more...)

“Do You Have A Key?”


“Don't you know anything at all about numbers?"
"Well, I don't think they're very important," snapped Milo, too embarrassed to admit the truth.
"NOT IMPORTANT!" roared the Dodecahedron, turning red with fury. "Could you have tea for two without the two — or three blind mice 
without the three? Would there be four corners of the earth if there weren't a four? And how would you sail the seven seas without a seven? (more...)

Password validation takes a while, how cool is that!!

You log in to your favorite web app and it takes a little while to get your login validated, or your password consumed, depending on your take on things,
or
You log in to your favorite APEX application, and after every 3rd shot, it takes a bit longer to retry

You are sure what you are doing and you are surely not drunk, but just mistyped the ****-password.

It is annoying, but is it?

UKOUG Tech16 Presentation Slides, Apex & Oracle Cloud

My presentation for UKOUG Tech 16 can be seen by following the link – Introduction to SOA CS. or see below   It was a tremendous 4 days (if you include the Tech stream’s Super Sunday).  If you are a UKOUG member and didn’t make it to the conference I’d look out for the material to be become available.

Whilst I’m not a big Apex fan (stitching business logic into the persistence layer feels wrong (more...)

Color Workshop at the Oracle Maker Faire

Workshop preparations

For the last 6 years, each Friday, I have been bringing a mobile painting studio to my kids’ school. Among other things, we work on what I call “color studies” – a set of formal exercises aimed to sharpen one’s sense of color and develop painting skill, just like musical scales, chords and arrpedgios sharpen one’s sense of harmony and develop performance skills. I was originally inspired to offer such level of formalism (more...)

Pac-Man on a String

Oracle hosted the first-ever company co-sponsored Maker Faire event on November 17, 2016.

When I heard of the event, I had something in my mind that I would encourage a group of middle-schoolers to make a game for the event. I have been teaching them occasionally on Arduino, NodeMCU and MQTT concept over some weekends, and this is the perfect opportunity to put them together in a build.

After some brain-storming, we came up with (more...)

Oracle Exadata Statement of Direction

There is a very interesting paper about the way of direction of the Exadata Database Machine.

Thanks a lot Günther Stürner.


Exadata GI Upgrade 11.2.0.4 to 12.1.0.2 + PSU Jul2016

giupg

Recently I did a upgrade to Grid Infrastructure 12.1.0.2 on a few Exadata Clusters

Here my summary of the installation

Before you start please read the following MOS note 1681467.1. This note is very helpful and describes the whole procedure in a Exadata environment

It’s not only the Upgrade to 12.1.0.2. In the same „session“ I also install the GI PSU Jul 2016 and the Oneoff Patch (more...)

Trip to Black (W)holes

imagination

Last week my kids’ school went on a field trip to the University of Santa Cruz to observe a black hole multimedia exhibition. We were invited there by Enrico Ramirez-Ruiz, the astrophysicist and the fellow parent at the school. When Enrico is not busy pushing the frontiers of science (he is impartial to violent explosions), he teaches astrophysics to children age 4 to 12.

The exhibition combined the visualized data from recent Extreme Mass (more...)
