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.

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?"

“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...)

Assertions in a future Oracle release

I just found this link on OTN to vote for including assertions in a future release of the Oracle database.

A great idea – please vote for it.

One of the most important votes this month…well, I do live in England! Smile

“Unstructured Data” – No such thing!

I keep hearing this term lately and I dislike it.

There is no such thing as Unstructured Data. All data has structure. If it didn’t have structure we wouldn’t be able to use it.

What about free text? Well, that’s just a single column value (stored in a CLOB in Oracle, for example) and the free text is, more often than not, on a row with other columns, such as identifiers and timestamps, i.e. (more...)

The Future of Work: What does a Smart Office look like today?

Editor’s note: We just returned from Holland last week where we attended AMIS 25, which was a wonderful show. One of the demos we showed was the Smart Office; Noel (@noelportugal) also gave a presentation on it.

We’ve been showing the Smart Office since OOW last year, and it remains one of our most popular demos because it uses off-the-shelf components that are available today, e.g. Amazon Echo, Leap Motion, Philips (more...)

“It’s … MUTATING!!!!”


“The most important reason for going from one place to another is to see what's in between.” 
― Norton Juster, The Phantom Tollbooth   

The mutating table error (ORA-04091) thrown by Oracle can be a familiar sight throughout a DBA’s career, along with the usual question of ‘Why?’. The error itself is not difficult to understand nor is it hazardous to the table data. Let’s look at why the error is thrown, why it’s (more...)

Maker Faire 2016

Another year, another amazing at the Maker Faire.

I’ve attended my fair share of Maker Faires these years, so the pyrotechnic sculptures, 3D printing masterpieces, and handmade artisan marketplaces were of no particular surprise. But somehow, every time I come around to the San Mateo fairgrounds, the Faire can’t help but be so aggressively fresh, crazy, and novel. This year, a host of new and intriguing trends kept me on my toes as I ventured through (more...)

Oracle’s Fashion Technology Makers: Soldering, Sewing, and Storytelling

Photo 18-05-2016, 11 14 39

Many hands make light (emitting diodes) work. Oracle Applications User Experience (OAUX) gets down to designing fashion technology (#fashtech) solutions in a fun maker event with a serious research and learning intent. OAUX Senior Director and resident part-time fashion blogger, Ultan “Gucci Translated” O’Broin (@ultan), reports from the Redwood City runway.

The Digital Hotel Key

Generally, I’m not in favor of consolidating important stuff onto my phone, e.g. credit cards, etc. because if I lose my phone, I’ll lose all that stuff too.

However, I’ve been waiting to try out a digital hotel key, i.e. using my phone to unlock my hotel room. Only a few hotels and hotel chains have this technology in place, and recently, I finally stayed at one that does, the Hilton San Jose.

#DBADev (Ops), who knows what is going on…

I have been considering writing this article for quite some time now.
APEX Connect 2016 in Germany’s capital Berlin and the DOAG Database days have finally persuaded me to talk more about #DBADev, let me explain why…

Whenever in the stone age…

During my career as DBA, I was always working closely together with Oracle Forms & Reports developers. In retrospect, the cooperation in that time was remarkable.
These Forms & Reports developers had always (more...)

Repeat After Me


“every time you decide something without having a good reason, you jump to Conclusions whether you like it or not.” 
-- Norton Juster, The Phantom Tollbooth

In an Oracle forum recently the following question was posted:


I have a request for 3 indices as shown below. Does the 1st index suffice for 2 and 3?  Do I need all 3?
 
    CREATE INDEX IDX_ATM_EM_EFF_VER_CURRENT_DEL ON ATM_xxx_SALARY
    (EMPLOYEE_KEY, EFFECTIVE_DT, SALARY_VERSION_NUMBER, IS_CURRENT, IS_DELETED);

    CREATE INDEX IDX_ATM_EM_VER_CURRENT ON  (more...)

“That Ain’t Right”


"Is everyone who lives in Ignorance like you?" asked Milo.
"Much worse," he said longingly. "But I don't live here. I'm from a place very far away called Context." 
-- Norton Juster, The Phantom Tollbooth 

Dates are, well, dates. They are not strings, they are not numbers, they are dates and to handle them properly the correct data type needs to be used. I can’t count how many times I’ve seen dates stored (more...)

Why GUI sucks…

Of course we all know GUI stands for Graphical User Interface, just as CLI stands for Command Line Interface, right!
Or, rather, a GUI is this nice, flashy screen where you can easily roam with your mouse, comparable to a multiple choice quiz, where the right answer is there for the picking.
A CLI on the other hand is this dark, mysterious blinking cursor… Nothing happens unless you know more or less what (more...)

Sangam 15

This was my 6th year at Sangam and as always was good fun. We were a group of 4 people who were traveling from Delhi and we reached Hyderabad on Friday morning. Just wanted to keep a day for visiting Ramoji Film City and also wanted to avoid the rush that morning travel on the conference’s starting day brings. So after dropping the luggage at the hotel we hired a taxi and reached Ramoji Film City. (more...)
