On Disney Parks, Data Science, Drones and Wearables

As the parent of a toddler, I have no choice but to pay attention to Disney and its myriad of products and services.

Case in point, this Summer we took our daughter to Disneyland for the first time, which was a whole thing. Pause to h/t Disneyland expert, Friend of the ‘Lab and colleague Kathy for all her park and travel protips.

Being who I am, I found myself wandering around Disneyland and California Adventure thinking (more...)

Behold: The Simplified UI Rapid Development Kit

Editor’s note: The recent release of the Oracle Applications Cloud Simplified User Interface Rapid Development Kit represents the culmination of a lot of hard work from a lot of people. The kit was built, in large part, by Friend of the ‘Lab, Rafa Belloni (@rafabelloni), and although I tried to get him to write up some firsthand commentary on the ADF-fu he did to build the kit, he politely declined. 

We’re developers (more...)

Context in UX – What it is, what it isn’t, and why it’s important

Our location is relentlessly tracked by our mobile devices. Our online transactions – both business and social – are recorded and stored in the cloud. And reams of biometric data will soon be collected by wearables.  Mining this contextual data offers a significant opportunity to enhance the state of human computer interaction. But this begs the question: what exactly is ‘context’ ?

Consider the following sentence:8594672237_09fb6c89b3_z

Personal Assistant or Creepy Stalker? The Rise of the Cognitive Computing

I just got back to my hotel room after attending the first of a two day Cognitive Computing Forum, a conference running in parallel to the Semantic Technology (SemTech) Business Conference and the NoSQL Conference here in San Jose. Although the forum attracts less attendees and has only a single track, I cannot remember attending a symposium where so many stimulating ideas and projects were presented.

What is cognitive computing? It refers to computational systems that (more...)

More First World Problems

I’ve been traveling a lot lately, which is bad. I’ve been consuming a lot of in-flight wifi, which is good, because there really should be no place on Earth where I’m unable to work.

Plus, it’s internets at 35,000 feet. How cool is that?

Today, I found myself in the throes of a decidedly first world problem. Of the many devices I carry, I couldn’t decide which one to use for the airplane wifi, which is, (more...)

Quadcopters and the Internet of Things

Editor’s note: Hey a new author! Here’s the first one, of many I hope, from Bill Kraus, who joined us back in February. Enjoy.

One of the best aspects of working in the emerging technologies team here in Oracle’s UX Apps group is that we have the opportunity to ‘play’ with new technology. This isn’t just idle dawdling, but rather play with a (more...)

“You’re A Real ACE”

Recently I was declared, for want of a better word, an Oracle ACE. I was nominated by someone I respect and admire; just the nomination itself was enough, really, to make my day. When I received notification that I had been selected I was truly surprised. I immediately thanked my nominator, who told me:


"Still, it is just a nomination form, and you did all the work that
made it so impressive. Congratulations!"

Honestly, (more...)

The Secret Project Emerges

Noel (@noelportugal) and Raymond have been working on a secret project. Here’s the latest:

OTN Latin America Tour 2014 – Mexico

keynote1

The OTN network is designed to help Oracle users with community generated resources. Every year the OTN team organizes worldwide tours that allow local users to learn from subject matter experts in all things Oracle. For the past few years the UX team has been participating in the OTN Latin America Tour as well as other regions.  This year I was happy to accept their invitation to deliver the opening keynote for the Mexico City tour stop.

That’s … Huge!

Recently I’ve noticed the occasional thread in Oracle newsgroups and lists asking about hugepages support in Linux, including ‘best practices’ for hugepages configuration. This information is out on that ‘world-wide web’ in various places; I’d rather put a lot of that information in this article to provide an easier way to get to it. I’ll cover what hugepages are, what they do, what they can’t do and how best to allocate them for your particular (more...)

It Pays To Be Smart

Exadata is a powerful system, able to provide exceptional performance. Much of this peformance is due to Smart Scans, Exadata’s mechanism for shifting the workload to the storage cells and having them filter and reduce the amount of data the database servers must process. Not every Smart Scan that starts ends up completing, though. Oracle may decide that a different path, one that doesn’t include a Smart Scan, may be more efficient. Certain conditions must (more...)

SQL Developer can’t start because MSVCR71.dll is missing (On Windows)

I have installed SQL Developer (with JDK) on Windows many times before, and almost all the time I receive the system error bellow when trying to execute it by the first time. Due to this, I decided to publish the

What A Performance!

Performance is one of the big watchwords in tht IT industry; nowhere is it more often used than in the database arena, and it’s usually not a good sign. End users know nothing, really, of the inner workings of the database yet they are the first to point the ‘finger of blame’ at the database when the processing speed slows or queries take longer than they would like to return data. [For end users performance (more...)

“A Ponderous Chain”

Chained and migrated rows in an Oracle database can seriously impact I/O performance, especially with Exadata. In a ‘normal’ Oracle database [read that as "non-Exadata, non-ASM" database] chained rows, in small numbers where that usually means 1% or less of the total rows in a table, are generally a nuisance. The performance hit they generate in such a situation is small and may not even be noticed by the end users. Add more chained/migrated rows (more...)

The next time anyone asks me what I do for a living I’m just going to point them to this YouTube video.

Problems when doing a V2V or P2V of a windows server to Oracle VM

Some time ago, I received the request to migrate some Windows 2008 Servers to my Oracle VM farm and after complete the P2V migration the newly create VM would not start. It would crash on boot with blue screen and error: STOP: 0x0000007B (0xXXXXXXXX,0xXXXXXXXX,0×00000000,0×00000000) This issue is related to the storage drivers needed for the guest […]
