New house, new life…
Ok, it’s not a new house, because i will stay here just for a few months, but is certainly a start of a new life! Next monday i will start on my new job, and the first impressions of São Paulo are very good.

I have created an album where i will upload SP’s pictures, so you are invited to look it!
Now i need to sleep…
peace.

Ok, now i can work…
Yesterday i did receive my personal computer, and now i can work again (the home desktop i cannot even touch… kids ;). I have my personal projects to work, and i believe now i will have more time for it.
So, now i need to download virtualbox, because i can’t wait for install the Solaris OS here!
peace.

A few minutes ago i did this post on OHAC community to hear what other people think about the idea. I guess would be nice to have a logo to our community, because that helps to promote the software and the community in general. Imagine that we could have logos on servers that are cluster members… would be nice, don’t you think? Something like: “This server is protected against failure”!

Please, give your feedback here on the comments section, or directly on OHAC discussion forum.
peace.

Hello all…

That is not my quote, but i agree a hundred per cent with it!
I’m going to a new challenge in my career, the company i will work for uses this slogan, and i will enjoy to persue that motto!
I think the best solutions are simple, and if there is complexity, it is there to fix “something” that was not so well implemented (we could not find a better solution), or to bring “today” something that “should” be here “tomorrow” (what normally needs a lot of complexity… among other things).

But what is simple?
For me, is something you can explain quickly (does not require a Ph.D to understand), cheap, clean, and easy to implement. But the real problem is figure out the simple solution. Actually, is the harder task…

Keep IT Simple is not easy at all.
For my friends that i leave in my last job (and city, because i’m moving to São Paulo), i have many thanks to distribute, and say that i will miss them a lot! I need to say that was not a simple decision too. For my blog readers, stay tuned for updates, i think we will talk a lot more about: Solaris, OpenSolaris, ZFS, NFS, AVS, iSCSI, HA, etc…

For now, it’s all i can say. Ok, i need to pack some stuff…
peace.

Sometime ago i was watching a television show (interviews), where the guest was a writer here in Brazil (and i think he is known world wide): Ziraldo. The show was: RodaViva, and the nice thing about it is the “format”. I don’t know what would be the better translation for it, but something like “alive circle”, “alive wheel”, or something… the guest stays in the center, with many reporters, columnists, surrounding him, making questions. The guest needs to spin from one side to the other for answer the questions.
What made me remember that show, was an article i was reading these days about changing habits, and more precisely, the traditional books for digital ones. The author was talking about the real evolution this kind of literature has reached, and give some examples like “we tell stories“, Amazon’s Kindle, iphone, and etc. So, two things came to my mind: one was my difficult to read a book or a more extensive article on the computer… i simply can’t. I’m old, and i’m sure is just my fault, but i need paper. ;-) The second was that Ziraldo interview. As you can see here, the interview date is 07/19/1999, almost ten years ago, and when asked about the digital books, he said:

Last night i was watching my daughter reading a history for her son, but was a well known history, and i did ask her why she was holding the book. She told me that She did want to show her son that the nice history he was listening was coming from that *thing*”.

I think that time we did not had anything like kindle for she use like today, but the interviewer were more depth in this topic and asked him why he did not like the digital books. He said: “I like to mark the text, to turn pages with my fingers..”. But another reporter told him that he could do that with some applications, you can mark the pages, turn it up, etc. And the answer was: “But i like mobility, take my book here and there…”. Ok, you can use a laptop. “Even to bathroom”? (did ask Ziraldo)… Why not? (said the interviewer) So he ends the question with:
“But if there is not toilet paper in the room, i can use the laptop too”?
;-)

Seems like my project proposal was approved on OHAC community, and now we need to wait for the setup of the project home page (thanks to Nicholas Solter, OHAC facilitator), and so on… but the work can not wait. So, i did post the first issue i think we need to discuss before the coding. Go to the OpenSolaris OHAC forum and give your insight about the topic. But you can help any time, with suggestions and critics about any feature we would like on this project. You can participate directly on the project site (when it’s ready ;-), sending me messages, or here on the blog as a comment (prefered way for now, so we can create a discussion around the topic).
peace.

As you know (or not ;), i have a little project to help handle LDAP authentication in GNU/Linux systems (somebody wants to help port it to OpenSolaris?), and a co-worker (Ernani), did a patch to adapt the code for the new ldap routines (ldap_init/initialize, etc). He give me his email (ernaniaz@gmail.com), if you have any questions. Many thanks to Ernani, and please give us feedback if you encounter any bugs.
PS.: This module (pam_hostscheck), works like a requisite in pam stack. Using a attribute (host) in the LDAP server, it checks if that user can “try” to authenticate on the machine/server. It’s one more level for security and access control.

I was talking with my friend Tirthankar (from OHAC community), and did want to hear from him how he was after the incidents that happened in his city (Bangalore bomb blasts). Thankfully not many people were hurt, and i could read on his blog, that people are not afraid and are going on with their normal lives. So, i did remember the movie “I am legend“, and the Bob Marley’s attitude cited by Dr. Neville (Will Smith):

“He had this idea. It was kind of a virologist idea.
He believed that you could cure racism and hate, literally cure it
by injecting music and love into people’s lives.
When he was scheduled to perform at a peace rally, a gunman
came to his house and shot him down. Two days later he walked out
on that stage and sang. When they asked him why - He said:
The people, who were trying to make this world worse… are not taking a day off.
How can I?
Light up the darkness.”

Peace.

Ok, sometime ago i did this post about globo.com using open source softwares, and the phrase “We are moving from Oracle to MySQL“, did create some comments on my blog like this. Now i did update that post with the presentation’s video (FULL), so you can watch the whole presentation!
You can watch and download the video directly on the linuxpark site.
ps.: Brazilian portuguese.
