On An Average Day


"There are other advantages," continued the child. "For instance, if one rat were cornered by nine cats,
on the average, each cat would be ten percent rat and the rat would be ninety percent cat. If you happened
to be a rat, you can see how much nicer it would make things."
-- Norton Juster, The Phantom Tollbooth

Recently an interesting question appeared on “Ask Tom” with regard to the ‘average’ between two dates. (more...)

BIAC Connected Communities, Connected Lives Hackathon

A couple weeks ago Noel (@noelportugal) and I were invited by the Oracle Apps UX Innovation Labs team to collaborate as technical mentors and judges in BIAC Connected Communities, Connected Lives hackathon.

What would be the best place to hold a hackathon? Cancún. Beautiful weather, beautiful beach, Mexican food, what else could I ask for?

This hackathon was organized around the 2016 Organisation for Economic Co-operation and Development’s (OECD) Ministerial Meeting on the Digital Economy (more...)

The Appslab’s Latest Inter-state Adventure: A Site Visit to Micros

 

Probably the best way to get to know your users is to watch them work, in their typical environment. That, and getting to talk to them right after observing them. It’s from that perspective that you can really see what works, what doesn’t, and what people don’t like. And this is exactly what we want to learn about in our quest to improve our users’ experience using Oracle software.

That said, we’ve been eager (more...)

Blast from the Past: Gesture-Controlled Robot Arm

Hard to believe it’s been nearly three years since we debuted the Leap Motion-controlled robot arm. Since then, it’s been a mainstay demo for us, combining a bit of fun with the still-emergent interaction mechanism, gesture.

Anthony (@anthonyslai) remains the master of the robot arm, and since we lost access to the original video, Noel (@noelportugal) shot a new one in the Gadget Lab at HQ where the robot arm continues (more...)

The Nextbit Robin

For a couple of months, I’ve been using as my main phone the Nextbit Robin. A $299 Android phone that started as a campaign in Kickstarter, and it got 3,611 backers including Jake (@jkuramot).

I previously had my Nexus 5, but over the time, Bluetooth stopped working and that was a good excuse to try this phone.

Also I was so excited because at SXSW I had a long talk with the Nextbit (@ (more...)

Size Does Matter


"You see, to tall men I'm a midget, and to short men I'm a giant;
to the skinny ones I'm a fat man, and to the fat ones I'm a thin man."
-- Norton Juster, The Phantom Tollbooth

Someone in one of the Oracle forums asked the following question:


How to estimate datafile size of tablespace when it is almost full? Could someone please explain?

which is ambiguous to say the least, since no (more...)

Ultra Subjective Space

Architects design space. A building is just a way to create spaces. Information architects at Oracle design relationships with abstract concepts. So far the main way we have to create visible spaces for our users is by projecting pixels onto glass screens.

This may change someday. If the promise of virtual reality is ever achieved, we may be able to sculpt entirely new realities and change the very way that people experience space.

From BI to AI: Whose Intelligence is Better?

Numbers are a property of the universe. Once Earthians figured that out, there was no stopping them. They went as far as the Moon.

We use numbers in business and life. We measure, we look for oddities, we plan. We think of ourselves as rational.

I, for one, like to look at the thermometer before deciding if I shall go out in flip-flops or uggs. But I cannot convince my daughter to do the same. She (more...)

He’s Making A List


"But I suppose there's a lot to see everywhere, if only you keep your eyes open."
-- Norton Juster, The Phantom Tollbooth

Recently a tweet by Chris Saxon (@chrisrsaxon) with respect to SQL, the language and implementation, started a list of contributions which should cause people to think a bit differently about how the language works and how queries should be structured. The list, found here, is by no stretch of the imagination (more...)

ODTUG Kscope16

Just like last year, a few members (@jkuramot, @noelportugal, @YuhuaXie, Tony and myself) of @theappslab attended Kscope16 to run a Scavenger Hunt, speak and enjoy one of the premier events for Oracle developers. It was held in Chicago this time around, and here are my impressions.

Since our Scavenger Hunt was quite a success the previous year, we were asked to run it again to spice up the conference a (more...)

Ask Today for Training/Conferencing Tomorrow

It’s that time of year again. You’re jealous from hearing all about that fabulous conference your co-worker or Facebook buddy just got back from. You could NEVER make it a conference. Your company just doesn’t do that. If you want to go to a top-tier Oracle user group or industry conference next year,... [Read More]

Examining The Remains


"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?"

Bump Your Fonts Up Already

I try to keep my fonts ‘big’ – for folks reading my posts and for folks attending my sessions. I do lots and lots of live demo’s, and there’s a lot of code on the screen to keep track of. But I’ve generally not followed my own advice when working in a cmd shell. Oops! (adsbygo... [Read More]

A Two-Wheel Self-Balancing Robot: JBalancePI

Create a two-wheeled, self-balancing robot using Raspberry Pi 2 Model B with GPIO and I2C interfaces and Java 8 in part I of this new series by Jose Cruz. To control the robot's movement and balance, he uses three modules: a sensor that contains a three-axis gyroscope and an accelerometer, a pulse width modulation (PWM) servo driver, and a motor driver. These modules create a feedback control loop that balances the robot and automatically corrects (more...)

Why You Should Use Consultants

As you probably know by now, I’m a consultant. By consultant I don’t mean a person who sits in meetings and talks all day (even though I like to talk), I mean a professional services guy who can do DBA tasks and can design and execute projects. In many cases companies prefer to hire someone […]

Kscope16 Scavenger Hunt

Kscope16_1024_500

Our first scavenger hunt took place last year at Kscope15. After that we replicated the experience for OOW15 and then for UKOUG15. We have had great (more...)

“It Doesn’t Work”


“Since you got here by not thinking, it seems reasonable to expect that, in order to get out, you must start thinking.”
— Norton Juster, The Phantom Tollbooth

The Devil is in the details, however, in support forums and newsgroups, the Devil is just as present when the details are either sketchy or non-existent. Volunteers in such forums and newsgroups quite often hear the dreaded words “it doesn’t work”, followed by … nothing. No (more...)

Twilio Signal Conference – $Bash night

Twilio Signal Conference ended with an after-party called the $Bash night.  Twilio set up booths with geeky games like programming, program debugging, computer building etc..  They also had a foosball table for 16 people.  I think it is one of the nicest parties for geeks I attended so far.  It was a fun night with music, drinks, food and games, tuned for developers.

During that morning’s keynote, Jeff Lawson (Twilio Founder) had a virtual (more...)

Twilio Signal Conference – Sessions

Lets dive to the Twilio sessions.

The sessions are generally divided in the following 4 tracks:

  • Learn
    See the latest progress in software and cloud communications, talk shop with Twilio engineers who developed them, and get in to the details on how to use the software.
  • Inspire
    Hear from industry experts shaping the future of tech with the latest software.
  • Equip
    Get details on hurdles tricks and solution from Twilio customers on building communications with (more...)

Twilio Signal Conference – All about Twilio

This year I attended the Twilio Signal Conference.  Same as its first year, it was held in Pier 27, San Francisco.  It was a 2-day action-packed conference with a keynote session in the morning and sessions after till 6 pm.

The developer experience provided by the conference is superb comparing to a lot of other developer conferences nowadays.  Chartered buses with wifi were provided for commuters using different transits.  Snacks served all day.  6 30-minutes sessions for (more...)
