The main effect Facebook and LinkedIn had on my online behavior is that I’m not posting on my blog anymore. It’s also true that I don’t have the time anymore for long articles, but I am really loving my blog (now 6 years old… school boy) and will continue to publish here things that are too technical for Facebook and not business enough for LinkedIn.

Meanwhile, since the last post, I studied a lot on Oracle Data Integrator (ran 5+ workshops across EMEA), Oracle GoldenGate (very hot on my plate, built a machine we’re using for exercises and the corresponding lab book very appreciated on our workshops), Oracle Database Firewall, got GoldenGate Certified Implementation Specialist certification, was traveling a lot to various places in Europe, including a series of 7 weeks in a row, now chilling out a bit and making time for CISSP certification.

Certification status as of May 2011

What’s common to the 3 technologies above? Anybody? Yes, I’m trying to get heterogeneous, they are all dealing with other database systems as well.

Keep in touch.

P.S. Yes, I do hate as well Ubuntu 11.04, can’t wait for 11.10

Apex is a great tool for rapid web applications based on Oracle Database. It’s free, and if you’re happy with Oracle XE’s limitations, then it’s perfect, you have the database free as well. I’ve been following APEX for long time ago, since it was called HTML DB, and wrote 2+ years ago a guide how to install APEX on XE.

Now APEX 4.0.1 is GA and most of the people would like to upgrade. It’s very simple.

1. Download APEX from OTN

After I saw quite some interest on installing Webmin on Ubuntu 9.04 and 9.10, I decided to go ahead and do the same for 10.04 and 10.10. I also strongly believe Ubuntu is doing wrong by not including Webmin into their repository Webmin is doing a mistake by using a deprecated library and not leave everybody to take benefit of their great product.
For those unfamiliar with Webmin, it is a web interface for configuring your linux box without X server.

LATER EDIT: As Joe Cooper from Virtualmin (the guys making webmin) said in the comments, there’s no need anymore for libmd5-perl for webmin starting with 1.520. I tested and it’s true, now the whole installation can be done in 3 simple steps. Thanks Joe, now’s much better!

Having said these, let’s to the job: Read the rest of this entry »

I’ve been tasked to add some features (subversion is one of them) under a Virtual Private Server (cPanel WHM) on a Hosting site.

First I downloaded and unarchived subversion:

Since the last versions are requiring SQLite, I had to download and copy one file from sqlite folder to subversion folder: Read the rest of this entry »

I am a big fan of Ubuntu Server. It’s exactly what you need for a server, no fancy UI, just services.
Dealing with all the text configuration files can be a time consuming task and there is something that can help a lot. It’s called Webmin and it is a web interface for configuring your linux box.

You need to install first some perl-related libraries required by webmin:

Hey, Ubuntu 9.10 (Karmic Koala) is out of beta and is now available for download here.

To see what’s new just check the release notes. From my feeling after testing the beta, It’s pretty similar to 9.04 (Jaunty Jackalope) but with some package updates and improvements.

Don’t wait, go and take it.
