Great Xmas Stocking Stuffer: Lego-Like Electronics IoT Kit

| Dec 19, 2014
Do you know a little kid (or big kid) who would like playing with IoT electronics on Christmas Day? Well, here's a great stocking stuffer. It's the SAM Lego-Like Modular Electronics Kit for building IoT projects.

See:

Lego-Like Electronics IoT Kit

Here's a quote:

 The developer reckons that SAM 
 can be used to create remote-control 
 toy cars, phone-connected doorbells, 
 and intruder alarms.

 Pressure, proximity, and light-
 sensor building blocks can be used 
 to create Tweeting  (more...)

DNS Bind Server configuration on Solaris 11.2

The subject of this blog is "DNS Bind Server configuration on Solaris 11.2", but you will need to scroll half way down before getting to the meaty part.


Motivation:

This blogs provides additional details about the setup and subnets in the system which previously discussed in my blog entry SPARC T5-4 LDoms for RAC and WebLogic Clusters.

Here is a brief description of the hardware that was available for the test:

PeopleTools 8.54 Feature: Support for Oracle Database Materialized Views

One of the new features of PeopleTools 8.54 is the support of Oracle Database Materialized Views. In a nutshell, Materialized Views can be seen as a snapshot of a given view. When you query a Materialized View, the data is not necessarily accessed online, but instead it is retrieved from the latest snapshot. This can greatly contribute to improve query performance, particularly for complex SQLs or Pivot Grids.

Integrating Cloud Providers into NetBeans IDE (Part 3)

| Dec 19, 2014

Now that we (1) can register new Cloud providers under the Cloud node and (2) automatically enable the resources made available by our Cloud provider to be displayed under the Servers node, let's take the next logical step in the development of our generic Cloud provider plugin for NetBeans IDE.

And what is the next logical step? Well, when the user creates a new Java web application, whether Ant-based or Maven-based, they need to be (more...)

Introducing Oracle Learning Exchange

Setting up the ABV Sample with Agile 9.3.3

Hello all,

As we wrap up things towards the end of the year, I wanted to talk a little bit about how you can set up our Augmented Business Visualization sample PX with Agile 9.3.3.   If you are running Agile 9.3.3, and are using Agile EC to manage your 3D CAD data, it is quite simple to set it up so that users can create new ECRs or ECOs directly (more...)

Do You Really Need a Content Delivery Network (CDN)?

When I first heard about Amazon's offering called CloudFront I really didn't understand what it offered and who would want to use it.  I don't think they initially called it a content delivery network (CDN), but I could be wrong about that.  Maybe it was just something I didn't think I needed at that time.

Amazon states it well today (as you might expect).  The offering "gives developers and businesses an easy way to distribute (more...)

“Innovation in Managing the Chaos of Everyday Project Management” is now on YouTube

Reading Oracle memory dumps

Every DBA working with the Oracle database must have seen memory dumps in tracefiles. It is present in ORA-600 (internal error) ORA-7445 (operating system error), system state dumps, process state dumps and a lot of other dumps.

This is how it looks likes:

Dump of memory from 0x00007F06BF9A9E00 to 0x00007F06BF9ADE00

excerpted from The Twelve Days of NoSQL (http://iggyfernandez.wordpress.com/)

NoSQL and Big Data are “disruptive innovations” in the sense used by Harvard professor Clayton M. Christensen. In The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail, Christensen defines disruptive innovations and explains how they eventually lead to the failure of the established players who ignored them:

“Generally, disruptive innovations were technologically (more...)

Do You Know It All?

Last week’s Technology That Fits newsletter (sign up here) stimulated some interesting discussions. I showed the following graphic:

Doomed Projects

Everybody agreed that projects that choose good tools for good reasons are good, and projects that choose bad tools for bad reasons are bad. But some disagreed on Learning and Lucky categories above.

I call projects that choose good tools for bad reasons “lucky”. They are CMMI level 1 – sometimes they succeed, sometimes they fail, and they (more...)

Friday Philosophy – my Funniest “PC Support” Call in Years

Those of us who work in IT often find ourselves being called by friends and relatives to help with issues they have with their home computer. No matter what branch of IT we work in, it’s IT {they figure} so of course we can fix their PC problems. It’s like any scientist can probably explain what the Higgs Boson really is and reverse the polarity of the neutron flow.

Mothers and other elderly relatives are (more...)

OBIEE Enterprise Security

The Rittman Mead Global Services team have recently been involved in a number of security architecture implementations and produced a security model which meets a diverse set of requirements.  Using our experience and standards we have been able to deliver a robust model that addresses the common questions we routinely receive around security, such as :

“Whats considerations do I need to make when exposing Oracle BI to the outside world?”

or

“How can I make a flexible security (more...)

Re-establishing reference from Vagrant to VirtualBox VM

Stress in the middle to demo preparation: Vagrant refused to bring up my suspended VMs. The message is wrote:

D:GitHubbiemond-orawls-vagrant-12.1.3-infra-soa>vagrant resume soa2admin2
==> soa2admin2: VM not created. Moving on…

After some Googling I discovered that the link between Vagrant and my VM consists of a the file called “id” in the subfolder

This file contains nothing but UUID used by VirtualBox to identify the VM.

Unfortunately, this file was missing (not sure why).

Begin! Transformatie begint met irritatie, verwondering en …ACTIE!

Als je echt iets wilt veranderen, moet je last ondervinden of onderkennen. Vlucht je in gelatenheid en acceptatie of kies je voor creatief overwinnen? Vind motivatie, overwin tegenslag en kom verder. Op wat voor manier dan ook…

Regelmatig erger ik me aan kleine dingen. Nieuwe medewerkers of klanten verwijzen wel eens verwonderd naar zaken die eigenlijk niet goed (genoeg) zijn, maar wel ingesleten en geaccepteerd… Er zijn dan work-arounds beschikbaar, dus de last is net (more...)

The importance of backups and disaster recovery plans

Having tweeted, “When was the last time you practised the recovery of each of your production databases?”, a few days before, I was presented with a very real DR situation for my website.

On Wednesday my website went down while I was at my office Christmas lunch. I restarted it from my phone and it was all up, but I got a message saying one of the RAID1 disks was dead. I do nightly file system and (more...)

DATE row generator with DBMS_SCHEDULER

A recent question on the Oracle-L mailing list was about generating dates in a given period. If you had a string like 'MWF', all Mondays, Wednesdays and Fridays between the from- and to-dates should be generated.

That reminded me of a quiz on plsqlchallenge.com I did on using DBMS_SCHEDULER.EVALUATE_CALENDAR_STRING. I had created a table function to test calendar expressions - that might be useful for something similar to what was asked on the (more...)

Fun : Endorse my “new” skills…

For a bit of fun I’ve added the following “new” skills to my LinkedIn profile.

  • Crocodile Wrestling
  • Plate Spinning
  • Fragile Methodologies
  • Laundry

It would be really cool if we could get them to the top 4 in the list of my endorsed skills. Please make it a happy holiday by endorsing these. :)

Remember, this only works if you actively don’t endorse the other things!

Cheers

Tim…

PS. I’ve written before about how I think LinkedIn (more...)

Christmas – A time to give

It's Christmas time... It's a time for giving... It's a time for warm-hearted feelings...

But there are people battling for their lives against cancer, who may not have much energy left to enjoy the holidays. Almost everybody has family or friends whose life has been impacted by cancer. Let us all reach out however we can, help wherever we can, and let good thoughts go out to the victims.

All cancer is terrible - but (more...)
