Google Glass, Android Wear, and Apple Watch

I have both the Google Glass and Android Wear (Samsung Gear Live, Moto 360), and often times I wear them together.  People always come up with a question:  “How do you compare Google Glass and Android watches?”.  Let me address couple of the view points here.  I would like to talk about Apple Watch, but since it has not been officially released yet, lets say that shape-wise it is square and (more...)

Glorious Data Visualizations for Your Friday

If you’ve read here for more than a hot minute, you’ll know that I love me some data visualization.

This love affair dates back to when Paul (@ppedrazzi) pointed me to Hans Rosling’s (@hansrosling) first TED talk. I’m sure Hans has inspired an enormous city of people by now, judging by the 8 million plus views his TED talk has garnered. Sure, those aren’t unique view, but even so.

There’s an interesting (more...)

Memory Improvement

Oracle 12c (version 12.1.0.2) offers the option of using in-memory processing to speed things along. Called the In-memory option it’s installed when you install the 12.1.0.2 software. Using it can make a considerable difference in processing speed, provided you have sufficient resources (RAM) available. Let’s revisit an older example, on Bloom filters, and see if Oracle processes things any faster in-memory.

Looking again at the Bloom filter example using (more...)

Mind Control?

Editor’s note: Hey look, a new author. Here’s the first post from Raymond Xie, who joined us nearly a year ago. You may remember him from such concept demos as geo-fencing or Pebble watchface. Raymond has been busy at work and wants to share the work he did with telekinesis. Or something, you decide. Enjoy.

You put on a headband, stare at a ball, tilt your head back-forth and left-right . . . the ball navigates through a (more...)

Here We Grow Again

Cheesy title aside, the AppsLab (@theappslab) is growing again, and this time, we’re branching out into new territory.

As part of the Oracle Applications User Experience (@usableapps) team, we regularly work with interaction designers, information architects and researchers, all of whom are pivotal to ensuring that what we build is what users want.

Makes sense, right?

So, we’re joining forces with the Emerging Interactions team within OAUX to formalize a (more...)

Did You See Our Work in Steve Miranda’s Keynote?

Last week at OpenWorld, a few of our projects were featured in Steve Miranda’s (@stevenrmiranda) keynote session.

Jeremy (@jrwashley) tweeted the evidence.

Debra (@debralilley) noticed too. I wasn’t able to attend the keynote, so I found out thanks to the Usable Apps (@usableapps) Storify, which chronicled “Our OpenWorld 2014 Journey.”

And today, I finally got to see the video, produced by Friend of the (more...)

Teaching an old dog to Fish

Inspired by the recent furore around Shellshock I decided that it was time to try an alternative to bash. By the very grown up process of shutting my eyes and poking my finger at the results of a search for “shell” I ended up at fish shell, described by the project as “a command line shell for the 90s”. I’m presuming that this means the 1990s and is not a minimum age requirement.

ESP8266 – Cheap WiFi for your IoT

About a month ago, hackaday.com broke the news of a new Wifi chip called ESP8266 that costs about $5. This wireless system on a chip (SoC) took all the IoT heads (including me) by surprise. Until now if you wanted to integrate wifi to any DIY project you had to use more expensive solutions. To put this into perspective, my first wifi Arduino shield was about $99!

First-timer tips for Oracle Open World

Last week I had the great pleasure to attend Oracle Open World (OOW) for the first time, presenting No Silver Bullets – OBIEE Performance in the Real World at one of the ODTUG user group sessions on the Sunday. It was a blast, as the saying goes, but the week before OOW I was more nervous about the event itself than my presentation. Despite having been to smaller conferences before, OOW is vast in its (more...)

To Skip, Or Not To Skip

An interesting issue presented itself just recently with a logical standby database I manage. The database is used for generating reports and the client wanted to skip all DML activity for a given schema as it wasn’t necessary for reporting purposes. I had done this in version 10.2.0.x; it was a simple procedure on a low-traffic database:


alter database stop logical standby apply;
exec dbms_logstdby.skip('DML','','%')
alter database start logical standby apply;

iBeacons or The Physical Web?

For the past year at the AppsLab we have been exploring the possibilities of advanced user interactions using BLE beacons. A couple days ago, Google (unofficially) announced that one of their Chrome teams is working on what I’m calling the gBeacon. They are calling it the Physical Web (http://google.github.io/physical-web/).
This is how they describe it:

“The Physical Web is an approach to unleash the core superpower of the web: interaction on demand. People (more...)

Map Reading

Consider the following concept: When you are born you are issued a map showing the direction your life will take. Along the way people will come into your life and help you make sense of parts of that map. You may not know these people at the time but they will be important in establishing where you are to be headed and possibly what you should be doing. Eventually you can read the entire map (more...)

“ID, Please”

In a forum I frequent the following question was raised:

We see some sqls that have been running for a long time in our prod DB, 11.2. when we check the v$session, i see null sql ids for them.
The sql_address shows up as 00. I would like to know what these sqls are doing because they correspond to processes that are burning up
the CPU and driving the usage to > 85%.

Oracle OpenWorld and JavaOne 2014 Cometh

This time next week, we’ll be in the thick of the Oracle super-conference, the combination of Oracle OpenWorld and JavaOne.

This year, our team and our larger organization, Oracle Applications User Experience, will have precisely a metric ton of activities during the week.

For the first time, our team will be doing stuff at JavaOne too. Anthony (@anthonyslai) will be talking about the IFTTPi workshop we built for the Java team for MakerFaire back in May (more...)

eSP

eSPEnkitec’s Sizing and Provisioning (eSP) is a new internal tool designed and developed with Oracle Engineered Systems in mind. Thanks to the experience and insights from Randy Johnson, Karl Arao and Frits Hoogland, what began as a pet project for some of us, over time became an actual robust APEX/PLSQL application, developed by Christoph Ruepprich and myself, and ready to debut at Oracle Open World 2014.

This posting is about eSP, what it does, and (more...)

Our Very Own Wearable

Autonomous Quadcopters Playing Some Catch

Tony went to a talk by Salim Ismail (@salimismail), the Founding Executive Director of Singularity University recently. He may/may not post his thoughts on the talk, which sounds fascinating, but this video is worth sharing either way, and not just because we have quadcopter fever.

Yeah, that’s autonomous flight, So refer to the list of horrifying things that should not be allowed.Possibly Related Posts:

Wearables Should be Stylish

To no one’s surprise, Apple announced the Apple Watch today.

Very apropos because I just read Sandra Lee’s (@SandraLee0415) post over on VoX about fashionable tech, one of Ultan’s (@ultan) main talking points about wearables.

Ultan, our wearables whisperer, has style and flair; if you’ve ever met him, you know this. His (and Sandra’s) point about wearable tech needing to be stylish is one that Apple has made, again, to (more...)

Blooms

In Oracle releases 10.2.0.x and later join processing can be made more efficient by the use of Bloom filters, primarily to reduce traffic between parallel query slaves. What is a Bloom filter? Named after Burton Howard Bloom, who came up with the concept in the 1970s, it’s an efficient data structure used to quickly determine if an element has a high probability of being a member of a given set. It’s based (more...)
